Abstract

The utility model discloses a domestic electric-warming bag, comprising a bag body, a bag cover, a heat conducting disc and an electric heating sheet. The heat conducting disc is in a shape which is the Chinese character 'ji', and the periphery of the heat conducting disc is tightly pressed by a bakelite ring and fixed on the step which is arranged on the inner wall of the bag body. The electric heating sheet is arranged in the heat conducting disc, and the lower surface of a mica electric heating sheet is provided with an asbestos ring which is positioned on the upper surface of a heat radiation hole. The bag cover is provided with a through hole, and the surfaces of the bag body and the bag cover are provided with binding plastic layers. The electric-warming bag is also provided with a mains switch S1, a quick and slow gear switch S2, a quick gear display circuit and a slow gear display circuit. The use of the electric-warming bag is safer and more electricity-saving, and the electric-warming bag is provided with red and green indicator lights to indicate the working conditions of the quick gear and the slow gear.

Description

Bag is warmed up in family's electricity consumption

The utility model relates to a kind of electric kitchenware.

In the prior art, it is CN2210593Y that Patent Office of the People's Republic of China discloses a notification number October 25 nineteen ninety-five, name is called the utility model patent of " slow fire casserole ", it mainly is made up of loam cake, pot body, heat conducting disk, heat-preservation cotton, electrical heating wire, left and right sidesing post, left and right sides gripper shoe, loam cake covers on pot body, electrical heating wire is installed in the heat conducting disk, and heat conducting disk is separately fixed on the gripper shoe of the left and right sides by left and right sidesing post, and left and right sides gripper shoe is fixed on the liner.The shortcoming of this product is: 1. have the gap between heat conducting disk and the left and right sides gripper shoe, in a single day the soup juice in the heated container overflow, and will enter in the heater element in the heat conducting disk, causes open circuit fault; 2. cotton absorption of the easy insulation of the steam in pot caused electric leakage, uses dangerous; 3. long, unattended again because of the time of this product use, lack the user mode indicator lamp so must install.

The purpose of this utility model is: provide the electricity consumption of a kind of family to warm up bag, its more reasonable structure, use safer, speed heating shelves are arranged, and have indicator lamp to indicate its duty.

The technical solution of the utility model is: bag is warmed up in the electricity consumption of a kind of family, comprises that the bottom is provided with heat conducting disk and the electric heating sheets in the inclusion of louvre, the clad above the inclusion, the inclusion; Described heat conducting disk is " several " font, the periphery of heat conducting disk is pressed abd fixed on the set step of the inwall of inclusion by the bakelite circle, described electric heating sheets be equipped with mica insulation sheet up and down, electric heating sheets and mica insulation sheet are arranged in the heat conducting disk, be provided with asbestos ring below the mica insulation sheet, asbestos ring be positioned at louvre above, described clad is provided with air-vent; Described electricity is warmed up bag and also is provided with power switch S1 and control circuit.

The further technical scheme of the utility model is: bag is warmed up in the electricity consumption of a kind of family, comprises that the bottom is provided with heat conducting disk and the electric heating sheets in the inclusion of louvre, the clad above the inclusion, the inclusion; Described heat conducting disk is " several " font, the periphery of heat conducting disk is pressed abd fixed on the set step of the inwall of inclusion by the bakelite circle, described electric heating sheets be equipped with mica insulation sheet up and down, electric heating sheets and mica insulation sheet are arranged in the heat conducting disk, be provided with asbestos ring below the mica insulation sheet, asbestos ring be positioned at louvre above, described clad is provided with air-vent; Described electricity is warmed up bag and also is provided with power switch S1, speed gear switch S2, fast shelves display circuit and slow shelves display circuit; The surface of described inclusion and clad is provided with laminating layer.

The utility model has the advantages that:

1. because heat conducting disk is " several " font, and its periphery is pressed abd fixed on the set step of inclusion inwall by the bakelite circle, so even electricity is warmed up to wrap in when using, being heated container has a small amount of soup juice to overflow, also can not enter in the electric heating sheets and causes and open circuit.

2. this electricity is warmed up and is wrapped in the end and replaced heat-preservation cotton with asbestos ring, greatly reduces its water absorbing properties, also just significantly reduces the possibility of electric leakage, can be safer when it uses.

3. this electricity clad of warming up bag is provided with air-vent, can reduce when using that to warm up the airtight bag internal pressure that causes of bag too high because of electricity, also can reduce the steam in the bag simultaneously.

4. because the utility model is provided with speed gear switch and speed shelves display circuit, make the user can clearly know its duty in use, and can use fast shelves or slow shelves, reach more energy-conservation more purpose of power saving according to required selection.

5. because the surface that this electricity is warmed up bag is provided with laminating layer, make that the surface is cleaner, even and dirty later cleaning also more convenient.

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Wherein: 1. inclusion; 2. clad; 3. heat conducting disk; 4. electric heating sheets; 5. bakelite; 6. step; 7. asbestos ring; 8. louvre; 9. mica insulation sheet; 10. air-vent; 11. power switch S1; 12. speed gear switch S2; 13. laminating layer.

Embodiment: as shown in Figure 1 and Figure 2, bag is warmed up in the electricity consumption of a kind of family, comprises that the bottom is provided with the inclusion [1] of louvre [8], the clad [2] above the inclusion [1], heat conducting disk [3] and the electric heating sheets [4] in the inclusion [1]; Described heat conducting disk [3] is " several " font, the periphery of heat conducting disk [3] is pressed abd fixed on the set step [6] of the inwall of inclusion [1] by bakelite circle [5], described electric heating sheets [4] be equipped with mica insulation sheet [9] up and down, electric heating sheets [4] and mica insulation sheet [9] are arranged in the heat conducting disk [3], be provided with asbestos ring [7] below the mica insulation sheet [9], asbestos ring [7] be positioned at louvre [8] above, described clad [2] is provided with air-vent [10]; Described electricity is warmed up bag and also is provided with power switch S1[11], speed gear switch S2[12], fast shelves display circuit and slow shelves display circuit; The surface of described inclusion [1] and clad [2] is provided with laminating layer [13].During use, closed power switch S1[11], closed again speed gear switch S2[12], the resistance of resistance R 2 is very little, electric current through speed gear switch S2[12 and resistance R 2 to electric heating sheets [4], make electric heating sheets [4] consume maximum power, caloric value is big, promptly so-called fast shelves heated condition, the voltage that be added on the resistance R 2 this moment also is added on the red light emitting diodes V21, indicator lamp is red, and resistance R 1 is because resistance is very big, can be similar to think open-circuit condition; Disconnect speed gear switch S2[12], electric current through diode V1 and resistance R 2 to electric heating sheets [4], because diode V1 is only exchanging the negative half period conducting, so electrical heating elements is only consumed power and heating when negative half period also, promptly so-called slow shelves state, this state power consumption is about half of fast shelves, and energy-saving effect is remarkable, electric current after resistance 1 current limliting is through green LED V22, and indicator lamp is green; Disconnecting power switch S1[11] can make electricity warm up bag to quit work fully.
