Benefits of technology

[0007]As the internal space of the case is divided by the barrier, the heat transmission to the control unit is blocked, thereby preventing the control unit from malfunctioning or being damaged.
[0008]Furthermore, since the control unit is cooled by the air flowing by means of the fan, the malfunctioning and damage of the control unit can be further prevented.
[0009]In addition, the barrier blocks the air flowing toward the burner system by the fan so as not to affect the flow of the air to the mixing pipe unit.

Problems solved by technology

Here, the control unit may be easily damaged or malfunction due to the heat generated from the burner system.

first embodiment

[0023]FIG. 1 is a perspective view of a heating cooking appliance according a first embodiment of the present disclosure and FIG. 2 is an exploded perspective view of the heating cooking appliance of FIG. 1.

[0024]Referring to FIGS. 1 and 2, a heating cooking appliance of a first embodiment includes a case 2 defining a lower appearance of the heating cooking appliance and having an opened top, a ceramic plate 1 seating on a top of the case 2, and a top plate 3 covering an edge of the ceramic plate 1.

[0025]The heating cooking appliance an exhaust grill 31 that is formed on a rear portion of the heating cooking appliance to exhaust combusted gas and a switch 29 that is formed on a front portion of the ceramic plate 1 to control an on / off of the gas combustion.

[0026]The locations and structures of the exhaust grill 31 and the switch 29 may be varied. However, it will be understood that an exhaust portion for exhausting the combusted gas and a switch portion for controlling the on / off of...

second embodiment

[0133]A second embodiment is identical to the first embodiment except for a structure of the spark plug. Therefore, like parts will not be described in detail in the second embodiment.

[0134]FIG. 13 is a view of a spark plug according to a second embodiment.

[0135]Referring to FIG. 13, according to a feature of this second embodiment, a heat detecting rod 28 functions as an ignition rod of the spark plug 26.

[0136]In more detail, an ignition rod 27 protrudes toward the burner frame and a thermal detecting rod 27 for detecting a temperature of the glow plate 12 protrudes to a location spaced apart from the ignition rod 26.

[0137]When the current is applied to the ignition rod 27, the spark plug 26 ignites the mixture gas by generating sparks between the thermal detecting rod 28 and the ignition rod 27.

[0138]The thermal ignition rod 28 is inserted in the burner frame 11 and extends to an external side of the burner frame 11. A support 23 supporting a thermostat 24 is installed on an exten...

third embodiment

[0140]A third embodiment is identical to the first embodiment except for a structure of the heating elements. Therefore, like parts will not be described in detail in the third embodiment.

[0141]FIG. 14 is a perspective view of a sub-heating unit according to a third embodiment.

[0142]Referring to FIG. 14, a heating element 356 is formed in a coil shape and coupled to the supporting member 352. The, coil-shaped heating element 356 is coupled to the supporting member 352 while having predetermined elastic force.

[0143]Therefore, after the heating elements 356 are heated, the heating elements 356 is not drooped but horizontally tensioned, thereby not contacting the glow plate 12.

[0144]The heating element is formed in a coil shape to have the elastic force in this embodiment. However, the catching portions of the supporting member, to which the heating elements are coupled, may be designed having elastic force.

Abstract

A heating cooking appliance is provided. The heating cooking appliance includes a case, a plate covering a top of the case, a burner system generating heat by combusting mixture gas in the case, a control unit controlling operation of the burner system, and a temperature increase preventing unit preventing a temperature of the control unit from increasing by the heat generated from the burner system. The temperature increase preventing unit is installed on the case.

Description

TECHNICAL FIELD[0001]The present disclosure relates to a heating cooking appliance.BACKGROUND ART[0002]A heating cooking appliance is a kitchen appliance that can cook food over a heat. Particularly, the present disclosure relates to a gas cooktop that can cook food over heat generated by gas combustion. The cooktop may also be called a hot plate or hob, which has been increasingly used in recent years.[0003]The heating cooking appliance includes a burner system that combusts gas. A plate is heated by the combusted gas to cook the food lying on a top surface thereof. The heating cooking appliance using gas combustion requires improvements in combustion efficiency.[0004]In the burner system, a control unit for, for example, the gas combustion and the like is provided on a side portion of the burner system. Here, the control unit may be easily damaged or malfunction due to the heat generated from the burner system. Therefore, there is a need to prevent damage to the control unit from ...
