Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a display device for a cooking appliance used in general households.

Conventional technology The conventional display device of this type of cooker was developed in 1973.
The configuration was as shown in Japanese Patent No. 17022, that is, the configuration as shown in FIGS. 4 and 5. In the figure, 1 is a cylindrical container body, 2 is an outer pot attached to the inside of the container 1 via a heat insulating frame 3, 4 is a heating element for cooking rice provided at the bottom of the outer pot 2, and 5 is a heating element for cooking rice. An inner pot 6 is removably placed on the body 4; an inner lid 7 covers the upper opening of the inner pot 5;
8 is a heat-retaining heating element arranged in a meandering manner around the upper side of the outer pot 2; 9 is a heat insulating material interposed between the container body 1 and the outer pot 2; , 10 is a mounting base for control components mounted on the outside of the container body 1, and an electronic circuit unit section 11 is mounted on this mounting base 10. 12 is an operating lever rotatably attached to the mounting base 10;
One end of the rice cooker 2 is connected to an automatic rice cooking switch 13 which is in thermal contact with the bottom of the inner pot 5, and an operation button 14 is attached to the other end. Reference numeral 15 denotes a temperature detecting section that is brought into close contact with the heat-retaining heating element 8, and this temperature detecting section 15 is held on the mounting base 10 via a heat insulating material 16. Reference numeral 17 denotes a box body that covers the control parts attached to the mounting base 10, and this box body 17
The upper part of the fitting part A is linear. On the other hand, the container 1 is formed with a bent portion 18 having an inverted L-shaped cross section so that the box 17 fits inside the container 1, and the contact surface with the box 17 is formed into a straight line. is formed.

Problems to be Solved by the Invention In such a conventional configuration, the box body 17 is
It is necessary to form the bent portion 18 having an inverted L-shaped cross section so as to fit inside the container body 1. In this case, it is difficult to process the bent portion 18, and there is a possibility that the cylindrical portion of the container body 1 may be deformed. Since the upper ends of the mounting portions of the box body 17 and the container body 1 have a small amount of bending, there is a problem in that water infiltrates through these parts, causing insulation deterioration and deterioration of the performance of electrical parts.

The present invention solves these conventional problems. Even if water drips onto the display panel from the top of the main unit, the product can always operate safely without water entering the control circuit. The purpose of the present invention is to provide a display device for a cooker that can be used.

Means for Solving the Problems In order to solve the above conventional problems, the present invention has the following features:
A rib that engages with an insulating cover that covers the wiring surface of the electronic circuit unit is provided on the inner upper part of the approximately box-shaped display board that houses the electronic circuit unit, and the height of this rib is higher than the bottom surface of the insulating cover. , and both ends of the rib are bent downward.

Function According to this configuration, water that has entered from the top of the display board collects on the top of the ribs, and some of the water falls from the bends at both ends, and the rest falls from the rib end faces, but at this time, the insulating cover Because the height of the ribs is higher than the bottom surface of the insulating cover, water either falls without being transmitted to the electronic circuit unit, or flows down the bottom surface of the insulating cover, causing water to enter the electronic circuit unit. Things will go away.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 3. In the figure, 21 is a cylindrical container, 22 is an outer pot attached to the inside of the container 21 via a heat insulating frame 23, 24 is a heating element for cooking provided at the bottom of the outer pot 22, and 25 is a heating element for cooking. An inner pot 25 is removably placed on the body 24, and the inner pot 25 is attached to the outer pot 2.
2, and is made of a material with excellent thermal conductivity. 26 is an inner lid that covers the upper opening of the inner pot 25; 27 is an outer lid that covers the inner lid 26; 28 is a heat-retaining heating element disposed around the entire circumference of the upper side of the outer pot 22; A heat insulating material 30 interposed between the pot 22 and the pot 22 is a substantially box-shaped display board that houses an electronic circuit unit 31 consisting of an operating section and a display section, and is attached to the side surface of the container body 21.
Reference numeral 32 denotes a rib provided on the inner upper part of the display board 30, and both ends of the rib 32 are bent downward. 33 fits into the electronic circuit unit 31,
The insulating cover 33 is an insulating cover that covers the wiring surface of the electronic circuit unit 31. Both shoulder R portions B of the insulating cover 33 engage with the bent portions A of both ends of the rib 32, and the bottom surface C of the insulating cover 33 engages with the bent portions A of the rib 32. It is installed deeply so that it is lower than the height, that is, the upper end D. 34 is a lead wire for transmitting a signal from the electronic circuit unit 31 into the container body 21.

Effects of the Invention As described above, according to the present invention, a rib that engages with the insulating cover that covers the wiring surface of the electronic circuit unit is provided on the inner upper part of the approximately box-shaped display board that houses the electronic circuit unit. The height of the rib is higher than the bottom surface of the insulating cover, and both ends of the rib are bent downward, so water that enters the display board from above the joint of the display board flows over the rib and is The part falls from the bent part at both ends of the rib, and
Since water will fall through the insulating cover and, as a result, water will not infiltrate into the electronic circuit unit, it is possible to prevent performance deterioration and insulation deterioration of the electrical components.
