Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a heating cooker that is incorporated into a kitchen cooking table, or is installed on a gas table or cooking table.
[0002]
[Prior art]
In the conventional cooking device, the display unit for displaying the operation state, the setting contents during operation or the trouble state is a vertical operation panel unit disposed on the front surface of the main body, or a top disposed on the upper surface of the main body. It is arranged on the plate part. The display element is generally an LED display device or a liquid crystal display device.
[0003]
As an example using an LED display device, there is JP-A-11-2412, and as an example using a liquid crystal display device, there is JP-A-07-094267.
[0004]
An example of Japanese Patent Application Laid-Open No. 11-2412 using an LED display device for the top plate will be described with reference to FIG. FIG. 5 is a plan view of this conventional example.
[0005]
The top plate 3 is provided with a left display unit 25, a right display unit 26, a middle display unit 27, and the like as display means in order from the left along the side on the near side. These display parts 25-27 are provided corresponding to each heating part, ie, heating devices 19, 20, and 21, and display thermal power and the like. And the display parts 25-27 are comprised with several LED element, for example, change the number of the LED elements to light, and display according to the stage of an output. Accordingly, when the number of heating units, the number of output stages of the heating unit, and the like are large, the number of LED elements is also large.
[0006]
In the example of Japanese Patent Application Laid-Open No. 07-094267, a liquid crystal display device is used, but in a commercialized product, the position of the liquid crystal display device is not the top plate portion, but a vertical operation panel disposed on the front surface of the main body.

[0008]
In addition, the liquid crystal display device can display characters, figures, etc., and the LED display device can be composed of one or several liquid crystal elements, whereas the LED display device requires a large number of LED elements. It is excellent as an element.
[0009]
In other words, the display unit that displays the operating state and the like is excellent in that the arrangement is a top plate unit and the display element is a liquid crystal display device. However, when trying to realize this, the distance between the liquid crystal display device and the heating device is excellent. Is close.
[0010]
For this reason, if the display part is simply the top plate part, it will be greatly affected by the heat generated by the heating device, etc., resulting in a high temperature atmosphere.
[0011]
However, since the rated temperature of the liquid crystal display device is not high, problems such as short life and low reliability occur in a high-temperature atmosphere, making it difficult to use and disposing the top plate on the display unit.
[0012]
[Problems to be solved by the invention]

[0013]
To solve this problem, first, the atmosphere of the liquid crystal display device is kept at a low temperature. In order to keep the atmosphere of the liquid crystal display device at a low temperature, it is necessary to cool the liquid crystal display device by applying cooling air thereto.
[0014]
However, the place where the product is placed is in the kitchen, and since oily smoke is generated from the cooking ingredients, dust and oily smoke are included in the cooling air, and these are blown to the liquid crystal display device, and the display If it adheres to the surface, the display content becomes difficult to see. Cleaning of the display surface of the liquid crystal display device is sufficient, but the liquid crystal display device is on the lower side of the top plate, so the product must be disassembled to clean it, and the user disassembles the product. Since it is difficult to do so, it is very problematic that dust or oily smoke adheres to the display surface of the liquid crystal display device.
[0015]
The present invention solves the above-mentioned problem, reduces the influence of heat generated by the adjacent heating devices, maintains the atmosphere of the liquid crystal display device at a low temperature, and at the same time, dust, oil smoke, etc. contained in the cooling air An object of the present invention is to realize a cooking device in which the liquid crystal display device is not attached to the display surface of the liquid crystal display device and the liquid crystal display device is arranged on the display portion of the top plate.
[0016]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention has a top plate disposed on the top surface of the main body, and a display unit that displays the operation state and the like is disposed on the top plate, and is placed on the top plate inside the main body. In a heating cooker in which a heating device for heating a load and a cooling fan for cooling the heating device are provided, and the main body includes an intake port and an exhaust port for the cooling fan, a liquid crystal display device is provided below the display unit. The liquid crystal display device is arranged in a cooling air passage between the intake port and the exhaust port, and a gap between the upper periphery of the liquid crystal display device and the lower surface of the top plate is sealed with a display packing, An elastic body that urges the display packing upward is disposed , and a flange that is inclined obliquely outward is provided over the entire circumference of the contact surface with the lower surface of the top plate of the display packing .
[0017]

[0055]
As a result, even if the liquid crystal display device and the heating device are close to each other and the temperature of the atmosphere of the liquid crystal display device increases due to the influence of heat generated by the heating device, the cooling fan is driven and the liquid crystal display device is Since the cooling is performed, the atmosphere of the liquid crystal display device is always kept at a low temperature.
[0056]
At the same time, the display surface of the liquid crystal display device is surely shielded from the cooling air by the display packing, the display support part, the elastic body, etc., so that the cooling air is blown on the display surface of the liquid crystal display device and dust or oily smoke is generated. There is no adhesion and the display content is not difficult to see.
[0057]
Therefore, it is possible to realize a cooking device in which the liquid crystal display device is arranged on the display portion of the top plate.
[0058]
At the same time, an elastic body that urges the display packing upward via the display support portion is disposed, so that the possibility of a gap between the lower surface of the top plate and the display packing due to the dimensional variation of each component is eliminated. . For this reason, the effect that the disassembly cleaning when dust, oil smoke, etc. adhere to the display surface of a liquid crystal display device becomes unnecessary is also acquired.
[0059]
In addition, by providing a flange that is inclined obliquely outward over the entire circumference of the contact surface with the lower surface of the top plate of the display packing, coupled with the action of the elastic body from below, the display packing and the top plate The degree of adhesion with the lower surface can be further ensured. In addition, since the flange is inclined obliquely outward, the gap between the flange and the lower surface of the top plate is not widened even when cooling air is blown. Therefore, the display surface of the liquid crystal display device is more reliably shielded from the cooling air, and dust, oily smoke, and the like are not attached.
