The pair of side wall portions respectively includes a pair of concave portions recessed in a third direction. The pair of protrusion portions is respectively disposed in the pair of concave portions.

A heating cooking apparatus includes a heating cooking chamber (A), a first air sending unit (), and a second air sending unit (). The heating cooking chamber (A) accommodates an object to be heated. The first air sending unit () supplies a first hot air (F) to the heating cooking chamber (A). The second air sending unit () supplies a second hot air (F) to the heating cooking chamber (A) from a direction different from the supply direction of the first hot air (F) supplied by the first air sending unit (). The heating cooking chamber (A) includes an accommodation space () that accommodates an object to be heated.

A heating cooking apparatus includes a heating cooking chamber (A) and an air sending unit (). The heating cooking chamber (A) accommodates an object to be heated. The air sending unit () supplies hot air (F) to the heating cooking chamber (A). The air sending unit () includes a suction hole portion (D) positioned on a predetermined side of the heating cooking chamber (A) and a blow-out hole portion (C) positioned on the predetermined side. The air sending unit () suctions air inside the heating cooking chamber (A) through the suction hole portion (D) and blows air into the heating cooking chamber (A) through the blow-out hole portion (C).

A heating cooking apparatus includes a microwave supply unit, a drawer portion, and a grid body made of metal. The microwave supply unit is configured to supply microwaves to a heating cooking chamber. The drawer portion is drawable with respect to the heating cooking chamber. A heated object is placed on the grid body. The drawer portion includes a moving body made of metal and an engagement portion made of non-metallic material. The moving body is configured to move between an accommodation position inside the heating cooking chamber and a drawn-out position outside the heating cooking chamber. The engagement portion is disposed on the moving body. When the moving body is at the drawn-out position, the grid body is engageable with the engagement portion.

A steam generating container A heated by a heat source includes: a water evaporation chamber into which water is supplied by a water supply device; a leading opening to lead steam from the water evaporation chamber, and ejection openings ejecting steam led through the leading opening into a heating chamber containing food. A buffer chamber connecting through the leading opening and with the ejection openings is provided between the water evaporation chamber and the heating chamber. Even when bumping water enters the buffer chamber through the leading opening, the bumping water having entered flows inside the buffer chamber. Thus, the bumping water is hardly ejected into the heating chamber through the ejection openings.

Cooking device

A heating cooker includes a body casing, a heating chamber, a magnetron that supplies microwaves into the heating chamber, a cooling fan that delivers cooling air flow to the magnetron, an air discharge duct that is for discharging discharge air from inside of the heating chamber to outside, a first guiding channel that guides into the heating chamber a portion of the cooling air flow from the cooling fan which has flowed out to a downstream side after cooling the magnetron, and a second guiding channel that guides toward the air discharge duct another portion of the cooling air flow from the cooling fan which has flowed out to the downstream side after cooling the magnetron.

Heating cooker

A packaging structure for a cooking device is so configured that a packaging material () with trays () packaged therewith is disposed in a heating chamber () with such an inclination that a one-side portion of the packaging material () becomes higher than the other-side portion of the packaging material (). Also, the one-side portion of the packaging material () is placed on a one-side-portion side tray holder (A). Further, a cushioning material () is inserted between an upper portion () of the heating chamber () and the one-side portion of the packaging material (), so that the one-side portion of the packaging material () is pressed against the one-side-portion side tray holder (A) while the other-side portion of the packaging material () is pressed against the other-side-portion side inner side surface () of the chamber.

Packaging structure for cooking device

Cooking device including buffer chamber

A cooker is equipped with a heating chamber having an open part in the front surface and holding an object to be cooked, an opening/closing door having a see-through window and opens and closes the open part, a suction intake opening opened in one of the side walls that faces the heating chamber, an air discharge outlet opened in the other side wall of the heating chamber, and a circulation duct having first and second side surface parts provided outside of the two side walls of the heating chamber and connecting the suction intake opening provided at the first side surface part and the air discharge outlet provided at the second side surface part. The cooker further includes a circulation fan provided inside the circulation duct and drawing in gas inside the heating chamber through the suction intake opening and blows it out through the air discharge outlet.

An open/close adjustment device is connected to the door of a heating chamber of a cooking device, and the open/close adjustment device pulls the door back to its totally closed position. The open/close adjustment device adjusts an operation force when the door is passing a predetermined open angle. The operation force indicates a maximum value when the door is passing the predetermined open angle, and the maximum value is given by two protrusions disposed at front-side and rear-side with distance between them. Each of the protrusions each produces a load when they go over a support member, and a following one of the two protrusions produces a load larger than a load firstly produced by a preceding one of the two protrusions when the door is opened.

A cooking device for performing cooking using a microwave and steam, in which a door of a heating chamber includes, as constituting components, an inner frame, a choke cover, and a gasket. The inner frame is made of metal and has at its periphery a choke structure constructed from a large number of comb teeth. The gasket is installed in the door with a base section of the gasket held between the inner frame and the choke cover. A lip section of the gasket has a bag-like cross-section whose side that faces the inside of the heating chamber is an entrance. The forward end of the lip section is bent to the door side. The comb teeth, except those positioned at the corners of the door, are bent at a larger angle than in a case in which the gasket is not installed.

A heating cooker includes a steam generator for generating steam for heating cooking, a removable water tank for storing water to be supplied to the steam generator, a pumpfor supplying water from the water tank to the steam generator, a drain valvefor draining water within the steam generator into the water tank, a first timer TMwhich starts counting when water is supplied to the steam generator by the pump, and an operation panelincluding a notification section for notifying of draining the water within the water tank. When the first timer TMhas counted over a first specified time, the control unitmakes the operation panelnotify of draining the water within the water tank.

A cooker has an external circulation path outside a heating chamber in which foods are to be placed. A blower sucks in gas inside the heating chamber, and forms, in the external circulation path, a gas flow that makes the sucked gas return to the heating chamber. Downstream of the blower, the external circulation path is provided with an exhaust port, in which a damper is provided. The damper closes the exhaust port during cooking, and opens the exhaust port when a door of the heating chamber is opened. After the damper is changed to a position of opening the exhaust port, the blower continues to operate until a predetermined condition is satisfied.
