A cooktop includes a knob assembly coupled to a control panel and controlling a heating part. The knob assembly includes: a knob body disposed at a front surface of the control panel and rotating around a rotation shaft, a knob ring disposed at a rear side of the knob body and having a diameter greater than a diameter of the knob body, a light diffusing part disposed between the knob body and the knob ring, and a light source part comprising one or more light sources irradiating light. A diameter of the light diffusing part is greater than the diameter of the knob body and less than the diameter of the knob ring, a front surface of the light diffusing part is exposed between the knob body and the knob ring, and one of the light sources irradiates light between the knob body and the knob ring.

Cooktop and knob assembly thereof

A cooktop includes a knob assembly controls a heating part. The knob assembly includes: a knob body disposed at a front surface of a control panel and rotating around a rotation shaft extended in a front-rear direction, a light diffusing part disposed at a rear side of the knob body and diffusing light, and a light source part disposed at a rear side of the light diffusing part and including one or more light sources. The light diffusing part includes a light source corresponding part disposed at a position corresponding to one of the light sources, and a thickness of the light diffusing part along a first straight line that passes from a center of the light diffusing part through the light source corresponding part is greater than a thickness of the light diffusing part along a straight line that does not pass through the light source corresponding part.

A cooktop includes a knob assembly coupled to a control panel and configured to control a heating part. The knob assembly includes: a knob body disposed at a front surface of the control panel and rotating with respect to a rotation shaft extended in a front-rear direction, a knob ring disposed at a rear side of the knob body and having a diameter greater than a diameter of the knob body, and a light source part disposed at the rear side of the knob body and including one or more light sources irradiating light to the rear side of the knob body. A portion of a rear surface of the knob body includes a first reflective surface reflecting light, and a portion of a surface of the knob ring includes a second reflective surface reflecting light, the portion of the surface of the knob ring facing the knob body.

A pump assembly and a cooking appliance having a pump assembly are provided. The pump assembly may include a cavity that defines a cooking cavity; a water supplier installed outside of the cavity; a connection pipe connected to the water supplier; and a pump assembly disposed outside of the cavity and connected to the connection pipe. The pump assembly may includes at least one pump; and a support made of a flexible material and coupling the at least one pump to an upper surface of the cavity.

Pump assembly and cooking appliance with pump assembly

A stacked oven may include a supporter installed between a first oven at a lower portion of the first oven and a second oven above the first oven and fixing the second oven at a position spaced apart upward from the first oven. The supporter may include a first installation member that includes a vertical extending member that contacts a side surface of the first oven, a lateral extending member that extends from an upper portion of the vertical extending member in a direction toward a center of the first oven, and a load support provided between a lower portion of the lateral extending member and the first oven; a second installation member that includes a lower surface support and a side surface support that contact a lower surface and a side surface of the second oven, respectively, and having an angle with respect to each other, and a guide that extends upward and outward from an upper end of the side surface support; and a connection member that vertically connects the lateral extending member and the lower surface support.

Oven

A cooking appliance is provided. The cooking appliance may include a guide that regulates an installation position of a water supply device with respect to a front panel. The guide may include a first guide coupled to the water supply device to align a relative position of a front surface of the water supply device with respect to the front panel, a second guide coupled to a guide protrusion to align a relative position of the guide with respect to an opening; and a fixer that fixes the guide to the cavity.

Cooking appliance

A cooking appliance includes a shaft protruding to an outside of a control panel; a knob installed in a way that encircles an outside of the shaft protruding to the outside of the control panel; a knob ring disposed between the control panel and the knob, and configured to guide a rotation of the knob; a supporter disposed between the knob and the knob ring, and shaft-coupled to the shaft to connect the knob and the shaft; and a support part disposed between the knob ring and the supporter and configured to narrow a gap between the knob ring and the supporter, or disposed between the knob ring and the knob and configured to narrow a gap between the knob ring and the knob.

A cooker device includes a main body that defines a cooking chamber and that defines an opening at a front of the main body, a door configured to open and close at least a portion of the opening, an opening assembly configured to apply force to the door and cause the door to pivot relative to the main body based on the force, a proximity sensor configured to sense a proximity of an object located in front of the cooker device, an input interface configured to receive an opening command based on the proximity of the object sensed by the proximity sensor, a control unit configured to, based on the opening command, control the opening assembly to apply force to the door, and a display that is configured to indicate an operating state of the cooker device.

A steel pipe pile and a steel pipe column is connected using a steel pipe socket. The connection method may include preparing the steel pipe socket including a socket supporting portion that covers an upper end surface of the steel pipe pile, and inserting a plurality of socket insertion portions extended downward from the socket supporting portion and having a plurality of socket grooves at a lower end portion thereof and a plurality of fastening members installed on the socket supporting portion. The method may also include inserting the socket grooves of the steel pipe socket into an upper end portion of the steel pipe pile and mounting the steel pipe column on the socket supporting portion. The method may further include fastening the steel pipe column and the steel pipe pile using the plurality of fastening members of the socket supporting portion.

Steel pipe socket and method of connecting steel pipe pile and steel pipe column using the same

Provided is a strengthening device to increase the strength of a grout layer. In the strengthening device, clamp members are interconnected and clamped to surround a grout layer on a concrete base, on which an upper structure is installed, so as to increase the strength of the grout layer. Connection members are provided to edges of the clamp members to connect the clamp members. Fastening means is fastened between the connection members in order to enable the clamp members to clamp the grout layer. This strengthening device acts as a mold to facilitate easy construction when grout is placed, and surrounds the grout layer to increase the strength of the grout layer after grout is cured, thereby effectively preventing and minimizing failure of the grout layer caused by loads transferred from an upper structure such as a column member or a bridge bearing.
