Description

Multi-functional electronic thermal-insulating bucket

The utility model relates to daily living article, especially a kind of multifunction electronic heat-preserving container that is used for food heat-insulation.

Present existing various heat-preserving containers (bottle), they all only have single heat insulation function, for example there is not the heat-preserving container (bottle) of electronic-controlled installation only to have the cold-hot heat preservation function of short time, electronic heat-insulating bucket (bottle) then only has 30 ℃ or 70 ℃ of constant temperature functions, and the constant temperature precision is not high.

The purpose of this utility model provides a kind of simple in structure, and is with low cost, can automatic accurate constant temperature when energized in 30 ℃ and 70 ℃, and safety electricity-saving has the multifunction electronic heat-preserving container of cold-hot heat preservation when disconnecting power supply.

Realize that the purpose of this utility model is to be made of loam cake, shell, inner bag, heat-insulation layer, heater, circuit control panel, temperature control thyristor, supply socket, temperature setting switch, the thick foam insulation device of 5-12mm is between inner bag and shell, heater is wrapped on the inner bag sidewall, the temperature control thyristor is close to wall of inner container and is installed in the heating body opening, the circuit control panel device is between shell and heat-insulation layer, and temperature setting switch is installed on the shell.

The utility model is on the basis of existing electronic heat-insulating bucket, the temperature setting switch and the circuit control panel thereof of temperature control thyristor and 30 ℃, 70 ℃ are installed, make it under the energising situation, when temperature setting switch places 30 ℃, 30 ℃ of constant temperature are promptly arranged in the utility model inner bag, when temperature setting switch places 70 ℃, 70 ℃ of constant temperature are promptly arranged in the utility model inner bag, during no power, the foam insulation that 5-12mm is thick makes it to have the function of cold and hot preservation food of long period, and it is simple in structure, and cost of manufacture is low, safe in utilization, power savings is good.

Describe in detail below in conjunction with accompanying drawing.

As Fig. 1, shown in Figure 2, profile of the present utility model is identical with the profile of existing various heat-preserving containers, as cylindrical, elliptical cylinder-shape, side's bodily form etc., between shell 1 and inner bag 3, be provided with the thick non-toxic foam heat-insulation layer 2 of 5-12mm, heater 4 is made around insulation board for heating wire, it is wrapped on the sidewall of inner bag 3 between inner bag 3 and heat-insulation layer 2, shell 1 all can adopt non-toxic plastic to make with inner bag 3, temperature control thyristor 6 is close to inner bag 3 outer walls and is installed in the hole of heater 4, circuit control panel 5 installs the bottom side at shell 1 between shell 1 and heat-insulation layer 2, be separately installed with temperature setting switch 7 on shell 1 lateral wall, supply socket 8, indicator light 9, the thick non-toxic foam heat insulation layer structure of 5-8mm is arranged, it and shell in the loam cake 10, the staving fitted seal snapping that inner bag 3 constitutes; Device has diode D1 on the circuit control panel 5, D3, controllable silicon T, resistance unit R2, R3, R4, R5, the D1 positive pole connects the lead of supply socket 8, negative pole sending and receiving hot body R1, the anode of T connects the other end of R1, the control utmost point of T connects the D3 negative electrode, negative electrode sending and receiving optical diode D2 and the R2 parallel circuits of T, another root lead of another termination supply socket 8 of its parallel circuits, R3 connects the anode of T, the anode of another termination D3 and temperature control thyristor TTS and the public connecting end of temperature setting switch K, " 1 " and " 2 " of K meet R4 and R5, R4 respectively, the control utmost point of another termination TTS of R5, the negative electrode of TTS connects the negative electrode of T.Here K, D2, TTS, R1 are respectively temperature control configuration switch 7, indicator light 9, temperature control thyristor 6, the heater 4 among Fig. 1, Fig. 2.

When the utility model was used for 30 ℃ and 70 ℃ of constant temperature, supply socket 8 was plugged on the AC power, when temperature control configuration switch 7 places " 1 ", 30 ℃ of constant temperature is arranged in the inner bag promptly, and wheaten food and make sour milk, rice wine etc. can be used to ferment; When temperature control configuration switch 7 places " 2 ", be that 70 ℃ of constant temperature are arranged in the inner bag, can be used for long-time insulation such as food and hot water, when temperature in the inner bag is higher than 30 ℃ of design temperatures or 70 ℃, the TTS conducting, the control utmost point of T is in electronegative potential, and T turn-offs, and circuit then stops heating, when temperature in the inner bag is lower than 30 ℃ of design temperatures or 70 ℃, TTS turn-offs, and SCR control is high potential very, the T conducting, circuit then continues heating, thereby making it automatic constant-temperature on 30 ℃ or 70 ℃ of setting, the fluctuation of its temperature is less than or equal to ± and 0.5 ℃, its result of use is splendid.When the utility model was used for the hot and cold insulation of food, its good heat insulation layer structure made it to have the hot and cold heat-insulating property of long period.
