Description

[Detailed Description of the Invention] The present invention relates to a timer mounting device for an electric cooker, which is most suitable for electric rice cookers, etc., and particularly prevents the timer device from being exposed to high temperatures and ensures electrical insulation.

Conventionally, timer devices used in electric rice cookers and the like are fixed within a mounting frame fixed to a notch provided in a side wall of a frame. However, in order to improve assembly ease, the mounting frame has a support bracket attached with a switch lever for turning on and off the heater, so the space distance between the terminals of the timer device and the support bracket or switch lever is limited. There is a risk of electric shock if the device comes in close contact with the device, and the radiant heat from the heater overheats the timer device, resulting in performance deterioration and thermal deformation of the timer case.

The present invention improves the above-mentioned drawbacks and will be described below with reference to the drawings. Reference numeral 1 denotes a frame having a vertically elongated notch 2 in the side wall, 3 an outer pot provided within the frame, 4 a heater attached to the exposed inner bottom of the outer pot, and 5 fixed to the cutout 2. It is a mounting frame made of a synthetic resin such as ABS resin that is vertically long and relatively easy to mold, and has a space 6 with a closed front on the lower inside, and mounting bosses 7, 7 are integrated on both sides of the space 6. It stands upright and has a through hole 8 bored in the upper part. 9
has an operating shaft 10 on the front and connection terminals 11 on the top.
11 is a timer device, and 12 is a timer cover molded from a relatively high heat-resistant resin mixed with a glass material that covers the rear surface of the timer device 9. Through holes 13 are provided on both sides and ventilation is provided at the bottom. A cutout hole 14 is formed for the purpose. Reference numeral 15 denotes a support fitting located between the heater 4 and the mounting frame 5 via the outer pot 3, and the upper part of which reaches approximately the upper surface of the mounting frame 5, and has a pair of mounting pieces 16 on the left and right sides of the upper part, respectively. An L-shaped heat shield plate 17 provided with a heat shield plate 16 is fixed, and is rotatably pivoted approximately at the center, and a knob 18 is fixed to one end to serve as an operating section.The other end senses the pan temperature and controls mechanical changes. A switch lever 19 connected to a generated heat sensitive body (not shown) and mounting pieces 2 on both sides
It consists of a mounting bracket 21 having a diameter of 0,20. 2
Reference numerals 2 and 23 indicate a timer set indicator lamp and a rice cooking indicator lamp provided in the mounting frame 5, 24 indicates a setting time adjustment dial rotatably provided on the front surface of the mounting frame 5, and 25 indicates a screw for the dial. 26,
26 is a substantially ring-shaped mounting plate rotatably attached; 27 is a rotatable desired time setting dial located in front of the setting time adjustment dial 24 and connected to the operating shaft 10; 28, 28, 29; 29 is a fixing screw, and 30 is a shaped overheating cover.

Next, regarding the assembly order, first, the lamps 22 and 23 are stored in corresponding positions in the mounting frame 5, and the timer device 9 is stored in the empty space 6, with its operating shaft 10 protruding to the front. Fix it with the mounting screws 31, 31. The time setting dial 24 is rotatably mounted on the mounting plate 25, and the desired time setting dial 27 is positioned in front of the time setting dial 24 and connected to the operating shaft 10. After this, place the heat shield cover 30 on the back side of the rice cooking indicator lamp 23 and fix the fixing screw 2.
Mounting pieces 16 and 1 above the heat shield plate 17 at 8 and 28
6 and the mounting frame 5, and place the timer cover 12 on the back side of the timer device 9, and fix the timer cover 12 with the fixing screws 29, 29.
The mounting pieces 20, 20 of the mounting bracket 21 are equally screwed onto the mounting bosses 7, 7 through the through holes 13, 13 of 2, thereby fixing the support bracket 15 and the timer cover 12.

In the present invention, the mounting bracket and the heat shield plate are assembled and integrated using separate parts, but a single metal plate may be appropriately bent and formed into an integral piece.

As described above, the present invention includes a frame having a notch in the side wall, a heater provided in the frame, a synthetic resin mounting frame fixed to the notch and having a space inside, and a A timer device that is housed and operated on the front side of the mounting frame; a timer cover made of synthetic resin that is located on the back side of the mounting frame and covers the rear surface of the timer device; and a timer cover that is located between the heater and the mounting frame and is L-shaped on the top surface. and a support metal fitting having a switch lever for turning on and off the heater and having an operation part facing inside the mounting frame, and the support metal fitting is connected to the cover with the timer cover interposed therebetween. At the same time, since the timer device is screwed and fixed to the mounting frame, the timer device has a double insulation effect with the heat shield plate and the timer cover to block radiant heat from the heater, and the timer cover also protects the connection terminals of the timer device, etc. In order to cover the live parts of the timer device, the timer device is completely surrounded by an insulating material, so there is no risk of metal parts such as support fittings and heat shields coming into contact with the live parts. In addition, since the timer cover is fixed to the mounting frame at the same time as the support metal fittings, assembly becomes extremely easy, and the dimensions of each part such as the switch lever, operating section, mounting frame, and support metal fittings can be easily controlled, making it possible to form one assembly. Parts management can be performed as follows.
