Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kitchen furniture equipped with a plug for adjusting the heating power of a gas combustor,
In particular, it relates to the mounting structure of the guide plate for cooling the appliance plug of the built-in kitchen furniture.

[0002]

2. Description of the Related Art In recent years, as one of kitchen equipments, a lot of built-in type kitchen furniture in which a range type oven having a plurality of gas burners at the upper part of the oven is incorporated in a system kitchen has come to be accepted. In such built-in kitchen furniture, when the oven is used, the hot air generated by the oven causes the temperature around the instrument plug that controls the heating power of the gas burner, the supply of fuel gas to the gas burner and the stop of the oven to be controlled without the oven. Compared with a thing, it becomes a high temperature of about 20 ° C to 30 ° C. In this way, when the temperature around the instrument plug becomes high, the specific gravity of the air inside the housing decreases and the weight of the air becomes lighter, and the amount of primary air sucked into the venturi pipe provided near the instrument plug is reduced. Will decrease.
Therefore, there is a problem that the combustion efficiency of the gas burner is reduced.

Therefore, conventionally, in order to prevent a problem due to a temperature rise of the air around the instrument plug and the Venturi tube, cooling air sucked from a ventilation hole formed in the housing of the built-in gas stove is guided to the instrument plug. There is known a built-in type kitchen furniture in which a guide plate for cooling the appliance plug is attached inside the housing.

[0004]

However, in the conventional built-in type kitchen furniture, the guide plate is fixed to the lower part of the housing or the base plate fixed to the lower part by a fixing screw dedicated to fixing the guide plate. Therefore, it becomes difficult to mount the guide plate, and if the fixing screw dedicated to fixing the guide plate is dropped into the bottom surface of the housing during the mounting work, the fixing screw cannot be taken out due to the existence of the functional parts of the housing. Therefore, there is a problem in that the functional component malfunctions due to the interference between the fixing screw and the functional component of the housing. In addition, since the guide plate must be provided with a screw fixing protrusion such as a flange portion, the shape of the guide plate becomes complicated and the material cost of the guide plate becomes expensive, which is a factor of increasing the manufacturing cost. There is a problem of being.

[0005]

It is an object of the present invention to reduce the material cost of the guide plate by simplifying the shape of the guide plate, and to reduce the number of parts by eliminating fixing members such as fixing screws dedicated to fixing the guide plate. In addition, it is to provide a kitchen furniture capable of reducing the manufacturing cost by simplifying the work of attaching the guide plate.
