Abstract
A semi-conductive thermostat comprises a main power source, an auxiliary power supply, a display control device, a refrigerating component, a heating component, a temperature sensor, a lighting lamp and a refrigerating/heating switch device, wherein the refrigerating/heating switch device is electrically connected with the refrigerating component and the heating component as well as the main power source and the display control device; and in switching of the refrigerating and the heating, the refrigerating/heating switch device provides varied voltage/current. With the structure, when the heating is switched to the refrigerating, the refrigerating/heating switch device provides voltage that is gradually reduced from 12 V working voltage to the heating component at first, and then provides low voltage, so that the voltage gradually rises till the 12 V working voltage is provided to the refrigerating component, which overcomes the defect that the service life is influenced by varied temperature difference of the refrigerating component; and if the refrigerating is switched to the heating, the voltage variation process is repeated.
Description
Technical field
The utility model relates to a kind of controlled-temperature cabinet, the controlled-temperature cabinet that especially a kind of conductor refrigeration piece is made.
Background technology
Present prior art, a kind of semiconductor thermostatic and temperature case comprise main power source, accessory feed, display control unit, cooling assembly, heat assembly, temperature sensor, cold/hot-swap device and illuminating lamp, and cooling assembly and the operating voltage that heats assembly are 12V.Existing problems are: heat when refrigeration is converted to, the environment that heats assembly is a low temperature, still adopts the starting of 12V operating voltage; Be converted to when refrigeration when heating, the environment of cooling assembly is a low temperature, still adopts the starting of 12V operating voltage; Thereby cause cooling assembly, heat assembly weak point in service life.
Summary of the invention
The purpose of this utility model is: a kind of semiconductor thermostatic and temperature case is provided, and it can provide by low voltage to change voltage to 12V when freezing and heat conversion, until to operating voltage 12V, improves the environment that freezes and heat assembly, has prolonged service life.
The utility model is achieved in that a kind of semiconductor thermostatic and temperature case, comprises main power source, accessory feed, display control unit, cooling assembly, heats assembly, temperature sensor and illuminating lamp, it is characterized in that: also comprise a cold/hot-swap device;
Described cold/hot-swap device and cooling assembly with heat electrical component and be connected;
Cold/hot-swap device is electrically connected with main power source and display control unit;
When refrigerating/heating switched, cold/hot-swap device provided the voltage/current of variation.
A kind of semiconductor thermostatic and temperature case of the utility model, owing to adopt such structure, as switching to when refrigeration by heating, cold/hot-swap device at first provides a voltage the supply system assembly that is reduced gradually by the 12V operating voltage, a low voltage is provided then, and voltage rises gradually, gives cooling assembly until the operating voltage of 12V, overcome cooling assembly like this and changed the temperature difference, influenced the defective in service life; Heat as switching to by refrigeration, cold/hot-swap device provides a voltage that is reduced gradually by the 12V operating voltage to cooling assembly, a low voltage at first is provided then, voltage rises gradually, give until the operating voltage of 12V and to heat assembly, overcome like this and heated the component variations temperature difference, influenced the defective in service life.
Description of drawings
Fig. 1 is the block scheme of circuit of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of semiconductor thermostatic and temperature case comprises main power source, accessory feed, display control unit, cooling assembly, heats assembly, temperature sensor and illuminating lamp,
Display control unit is connected with main power source, accessory feed, temperature sensor and illuminating lamp;
Also comprise a cold/hot-swap device; Described cold/hot-swap device and cooling assembly with heat electrical component and be connected; Cold/hot-swap device is electrically connected with main power source and display control unit.
In use, switched to when heating by refrigeration, cold/hot-swap device provides a voltage that is reduced gradually by the 12V operating voltage for cooling assembly; Cold then/hot-swap device provides a voltage that is raise gradually to the 12V operating voltage by low voltage for heating assembly.
Switch to when refrigeration by heating, cold/hot-swap device provides a voltage that is reduced gradually by the 12V operating voltage for heating assembly; Cold then/hot-swap device provides a voltage that is raise gradually to the 12V operating voltage by low voltage for cooling assembly.
Above-described only is preferential embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the utility model principle, can also make some improvement and modification, this also is considered as protection domain of the present utility model.
