Abstract
The invention discloses a single-chamber hot and cold insulation switching box, which comprises a box body, wherein, the box body is provided with a single high temperature chamber and a single low temperature chamber; the high temperature chamber and the low temperature chamber are respectively provided with a cooling system and a heating system arranged in parallel. The cooling system comprises a cold compressor, a condenser connected in series with the cold compressor, a dry filter and a cooling temperature controller; the heating system consists of a heater, a temperature controller and an overheat protector. As the box body box of the invention is provided with the single high temperature chamber and the single low temperature chamber, and the high temperature chamber and the low temperature chamber are respectively provided with the cooling system and the heating system which are arranged in parallel, therefore, the device has two functions, i.e., low temperature chamber function (assuming 18 DEG C below zero) and high temperature room (assuming 50 to 80 DEG C above zero); the device can be used for multiple purposes, saves fixed-asset investment for enterprises, and the use is convenient.

At present, according to the market demand, cold drink will be sold in summer on the one hand by the trade company that has, and will sell the beverage of heat on the other hand winter, and a kind of in the market product can not satisfy above-mentioned requirements simultaneously, have to buy a refrigeration product, buys one again and heats product.Trade company has just increased the input of fixed assets like this, uses also inconvenient.
Summary of the invention
Purpose of the present invention just is to provide a kind of single chamber cold-hot heat preservation converting box that can possess refrigeration and heat-production functions.
Purpose of the present invention can realize by following measure:
The present invention includes casing, in casing, be provided with single high low temperature chamber, refrigeration system parallel with one another and heating are set respectively in high low temperature chamber.
Refrigeration system is made of refrigeration compressor, the condenser of connecting with refrigeration compressor, device for drying and filtering and refrigeration temperature control device among the present invention; Described heating system is by the heater that is cascaded, and temperature controller and overheat protector constitute.On heating and refrigeration system, be mounted with mechanical switch or electronic switch.Mechanical switch is single-pole double-throw switch (SPDT) or interlock switch.The Men Tiwei circular arc door of casing or plane sliding door or inclined-plane sliding door or folding door.The door body is transparence or opaque shape.The refrigeration temperature control device is mechanical type or electronic type.Electric heater is electromagnetic oven or PTC heating element heater or electrothermal tube or the resistance wire made by alloy material or carbon fibre material.Casing is the low boy cabinet or the vertical cabinet of band heat-insulation layer.
The present invention is provided with refrigeration system parallel with one another and heating respectively owing to be provided with single high low temperature chamber in casing in high low temperature chamber.Thereby can realize two kinds of functions of a device, first kind is low temperature chamber (supposing-18 ℃), and second kind is hot room (supposing 50-80 ℃); Reach a tractor serves several purposes, trade company can save investment in fixed assets and convenient the use.
Description of drawings
Fig. 1 is a system schematic of the present invention;
Fig. 2 is an electrical schematic diagram of the present invention;
The specific embodiment
The present invention does with detailed description below in conjunction with drawings and Examples:
Embodiment 1
As shown in the figure, in Fig. 1 system schematic, A: refrigeration compressor, B: the signal when high low temperature chamber is in low temperature, B ': the signal when high low temperature chamber is in high temperature.C: capillary, D: device for drying and filtering, E: condenser, F: heater.In Fig. 2 electrical schematic diagram, label 1: attaching plug, label 2: power supply indicator; label 3: heater switch; label 4: electric heater unit, label 5: heating temperature control device, label 6: cross thermal cut-off; label 7: burner on light; label 8: refrigeration temperature control device, label 9: refrigerating operaton indicator lamp, label 10: overload protective device; label 11: compressor, label 12: starting relay.The present invention includes casing, in casing, be provided with single high low temperature chamber, refrigeration system parallel with one another and heating are set respectively in high low temperature chamber.
Specifically: the present invention includes refrigeration system and be parallel with single-pole double-throw switch (SPDT) and heater, overtemperature protection and heating temperature control device, power supply indicator, compressor also are housed, the indicator lamp of electric heater unit work in refrigeration system.
