Abstract
The utility model relates to a temperature control electric heating lunch-box which comprises a box body and a box cover, wherein the box body consists of a shell and an inner box, and an insulating layer (8) is arranged between the shell and the inner box. The temperature control electric heating lunch-box is characterized in that the bottom of the inner box (1) is provided with a heating plate (2) which is connected with a power circuit (3) in series by a lead; the power circuit is provided with a manual control switch (4), a temperature control switch (5) and a temperature controller (6), wherein the output end of the temperature controller (6) is connected with the control end of the temperature control switch (5), and the input end of the temperature controller (6) is connected with the output end of a temperature sensor (7) arranged on the heating plate (2). The temperature control electric heating lunch-box is simple in structure and convenient for use, and not only can be used for heating, but also for heat preservation; furthermore, the lunch-box is internally provided with the temperature controller which can be used for controlling a power supply to be automatically cut off when the temperature reaches to a certain range, thus avoiding the potential safety hazard for the people caused by heating for a long time.
Description
Technical field
The utility model relates to tableware, particularly a kind of thermostat galvanothermy lunch box
Background technology
Present many working clans and student can not go home to have a meal because main leaving home is far away noon, and the not only consumption of having a meal outside is high, nor are health very, so just select the own meal of being with.Morning band food to noon just cool, micro-wave oven heating food can be prepared for the office worker by some company, micro-wave oven is not prepared by most of company and school.In order to solve the problem of hot meal, people have developed heatable lunch box.Existing heating lunch box structure is complicated, and does not have attemperating unit, if in hot meal, owing to the time has been forgotten in working and learning, is easy to occur safety problem.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, the heating effective, the thermostat galvanothermy lunch box that security performance is high.
Described thermostat galvanothermy lunch box comprises box body and lid, box body is made up of shell and inner box, between be provided with heat-insulation layer, it is characterized in that: portion is provided with heating plate at inner box, heating plate is connected with power circuit by lead, be provided with manual switch, temperature detect switch (TDS) and temperature controller on power circuit, the output of temperature controller is connected with the control end of temperature detect switch (TDS), and the input of temperature controller is connected with the output of temperature sensor on being located at heating plate.
The temperature of described temperature controller is set to 60 ℃-100 ℃.
The utility model is simple in structure, and is easy to use, not only can heat, but also can be incubated, in be provided with temperature controller, can control temperature and arrive certain scope, with regard to auto power off, avoiding for a long time, heating brings potential safety hazard to people.
Description of drawings
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is a circuit diagram of the present utility model.
Among the figure: 1-inner box, 2-heating plate, 3-power circuit, 4-manual switch, 5-temperature detect switch (TDS), 6-temperature controller, 7-temperature sensor, 8-heat-insulation layer, 9-power interface.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.Among Fig. 1, described thermostat galvanothermy lunch box comprises box body and lid, box body is made up of shell and inner box, between be provided with heat-insulation layer 8, it is characterized in that: be provided with heating plate 2 in inner box 1 bottom, heating plate 2 is connected with power circuit 3 by lead, is provided with manual switch 4, temperature detect switch (TDS) 5 and temperature controller 6 on power circuit, the output of temperature controller 6 is connected with the control end of temperature detect switch (TDS) 5, and the input of temperature controller 6 is connected with the output of temperature sensor 7 on being located at heating plate 2.The temperature of described temperature controller 6 is set to 60 ℃-100 ℃.
Food is contained in the inner box 1, during heating, only power line one need be terminated on the power interface 9 on the lunch box, the other end is inserted on the power supply, presses hand switch 4, and lunch box begins heating.When being heated to 100 ℃, the temperature sensor 7 on the heating plate 2 passes to signal in the temperature controller 6, and the control circuit in the temperature controller 6 makes temperature detect switch (TDS) 5 automatic disconnections, can not bring potential safety hazard because of long-time heating.Heat-insulation layer 8 can be incubated the food in the lunch box, and the food that makes the inside can be not cool in a period of time.If overlong time, when the temperature of food was lower than 60 ℃, temperature sensor 7 was passed to temperature controller 6 with signal, made temperature detect switch (TDS) 5 auto-closings, continued heating.
Claims (2)
