A pulse combustor comprises a throttle plate provided in a cylindrical body for dividing the interior of the body into a combustion chamber and a mixture chamber and having a throttle hole, gas suction holes communicating with the combustion chamber, air suction holes communicating with the combustion chamber, igniting plug provided in the combustion chamber for explosing and burning the mixture gas of the air and the fuel gas therein, and valve plate provided in the mixture chamber for shutting off the communication of the gas suction holes and air suction holes with the mixture chamber when the pressure in the mixture chamber becomes positive as the mixture gas is exploded and burnt and enabling the communication when the pressure in the mixture chamber becomes negative.

Pulse combustor

A cooking appliance comprising a heating chamber with a window provided on one side. At least one surface of the window is coated with a film of a reflecting metal oxide, such as indium oxide, to such a thickness that food in the heating chamber can be seen through the window.

Electric oven toaster

A hot water supply system comprises a base of cylindrical shape; a storage tank supported on the base, the tank having an upper end plate and a lower end plate supported on the base and defining, together with an inner face of the base, a soundproofing chamber; and a pulse combustor including a pulse burner attached to the lower end plate, and a tail pipe which communicates with the burner and is arranged inside the storage tank next to the lower end plate, the tail pipe having an ascending portion extending from the pulse burner toward the upper end plate, and a descending portion extending from a top end of the ascending portion toward the lower end plate to guide condensed water condensed inside the tail pipe to outside the storage tank. The system further comprises a blower, a suction muffler, and an exhaust muffler which are arranged inside the soundproofing chamber, the base having a soundproofing layer to shield noise generated in the soundproofing chamber.

Hot water supply system

In a liquid fuel combustion apparatus having a horizontal combustion cylinder including a peripheral wall provided with perforations through which air is supplied in the form of jets. A fuel supplying system includes a fuel reservoir provided at the lowermost portion of the combustion cylinder. Vaporized fuel is mixed with the air jets and is subsequently burnt as it is carried horizontally.

Liquid fuel combustion apparatus

A liquid fuel combustion apparatus comprises a combustion cylinder, a fuel reservoir, a housing, a blower and an electrical ignition heater. The reservoir is disposed inside the cylinder to store a liquid fuel supplied from outside of the cylinder. The housing is disposed outside the cylinder to create a space therebetween and has an end wall opposite to an end wall of the cylinder. The blower is disposed outside, and in a spaced apart relation to, the housing and supply air to the space. The heater is supported by the end walls and ignite liquid fuel stored in the reservoir.

A freezing refrigerator has a freezing chamber for accommodating food to be freezed and a cold chamber for accommodating food kept at low temperature, those chambers being separated by a heat insulative member and provided with doors, respectively. The cold chamber is provided therein a cold chamber cooler for cooling the inside thereof and the freezing chamber is provided therearound with a first freezing chamber cooler for cooling the inside therein. A second freezing chamber cooler is provided close to the rear side of the freezing chamber but is separated from the inner surface of the freezing chamber. The surface temperature of the second cooler is kept lower than that of the first freezing chamber cooler. A shield plate is further provided to blind one from seeing the second cooler when the door for the freezing chamber is open, the shield plate being disposed close to the second cooler.
