Abstract
The utility model discloses a refrigerated cabinet, which is mainly composed of temperature controllers, an air discharge fan, an air supply fan, an air discharge pipe, an air inlet pipe, an outer case, a cabinet door, etc. The main temperature controller and the subsidiary temperature controller are respectively arranged at the proper positions in the refrigerated cabinet and out of the refrigerated cabinet. The air discharge fan and the air supply fan are respectively arranged on the holes of the two half parts of the cabinet top. The air discharge fan and the air supply fan form a series circuit with the temperature controllers and the power supply after firstly connected in parallel. The main temperature controller and the temperature controller automatically control the switching of the circuit to cause the outer air and the inner air in the cabinet to be exchanged by the switches of the air discharge fan and the air supply of the controllers to maintain the appropriate temperature. The refrigerated cabinet is suitable for the indoor mass vegetable storage of the town household in the winter.
Description
The utility model belongs to a kind of cold storage plant.It is a kind of device of regulating its internal temperature by the operation of refrigerant.
Present family expenses cold storage plant (as refrigerator etc.) be to realize its effect by refrigerant such as consumes energy evaporation freon.It draws two problems: at first, use expensive refrigerant in a large number these people, but a large amount of cold airs in winter is ignored; In addition, be subjected to capacity limitation, refrigerator can not store vegetables (and for the most of town dwellers of China, it is essential storing a large amount of vegetables winter) in a large number.That is to say that people do not try every possible means to utilize the cold air in winter to store vegetables, its reason mainly be winter the air themperature of indoor and outdoor all can not be separately directly in order to store vegetables.
The purpose of this product of the utility model air cooling refrigerator finds a kind of cold air in winter that can utilize very easily to make refrigerant with regard to being, and can store the device of things such as vegetables in a large number.
This product primary structure accompanying drawings is as follows:
Accompanying drawing 1 is the audio-visual picture of this product, accompanying drawing 2 for this product by this product schematical top view of being seen in the cabinet, accompanying drawing 3 is a circuit diagram.
The numeral of marking represents respectively in the accompanying drawing: shell 1, liner 2, air inlet pipe 3, supply fan 4, blast pipe 5, exhaust fan 6, main temperature controller 7, auxiliary temperature controller 8, article rack 9, cabinet door 10, lead 11 etc. Wherein: liner is made by heat-barrier material, with basic partition cabinet Inside and outside exchange heat, infiltration. Row, supply fan and temperature controller also have the 220V power supply to be linked into a loop by lead. Temperature controller is by connecting, disconnect the open and close of the row of control, supply fan to circuit.
This principle of products is as follows: the essential suitable temperature " T " of the storage of vegetables. This product should be placed under the window during use, the row of making, air inlet pipe are stretched out outside the window, temperature controller are transferred to " T " position, close the cabinet door. Because the infiltration of Indoor Thermal air or enter or other when making in-cabinet temperature be higher than " T ", main temperature controller is connected circuit, row, supply fan are opened. At this moment supply fan sucks cold air by outdoor by air inlet pipe in cabinet, exhaust fan by blast pipe by in the cabinet to the turbid air of outdoor discharge heat. Through after a while, when in-cabinet temperature dropped to " T ", main temperature controller disconnected circuit, and row, supply fan are closed, and in-cabinet temperature just no longer descends and keeps the regular hour. If owing to infiltration or cabinet door or other reason of Indoor Thermal air, in-cabinet temperature rises again when exceeding " T " again, main temperature controller makes circuit connect again, and row, supply fan are opened, and temperature also will drop to " T " again. So repeatedly continuous, can make long-term automatically keep " T " in the cabinet. Just can realize indoor large quantities of long term storage vegetables.
When outdoor temperature was higher than " T ", the auxiliary temperature controller just made the cabinet inner looping disconnect, and row, supply fan just can not worked yet.Have only when outdoor temperature is lower than " T ", the auxiliary temperature controller just can make the loop connect.
The advantage of this product is: this product only uses winter outdoor cold air to come refrigeration, and inexhaustible cold air is used, and main is to store vegetables in the winter time in a large number.This product structure is simple, and its function is particularly useful for storing winter vegetables.
The implementation of this product is as follows: 1, set up cuboid shell and cabinet door, its material does not have specific (special) requirements, and volume size preferably can place the window below for good.2, lay liner at shell and cabinet door inwall.3, level is installed several roads article rack that can put arbitrarily, take off in cabinet.4, open two holes at the cuboid top, blast pipe, fan and air inlet pipe, fan are installed respectively on the hole.5, a main temperature controller is installed in cabinet, the auxiliary temperature controller is installed at the mouth of pipe place of stretching out an outdoor end in air inlet pipe.6, make main and auxiliary temperature controller be associated in into a loop with the power supply of row, supply fan and 220V.Like this, the critical piece of entire product just installs.During use, this product is placed under the indoor window, row, air inlet pipe are placed outside the window, mix up temperature controller, the cabinet door that closes gets final product.
In order to prevent that the cold air that has just absorbed from directly being discharged, can between row, supply fan, vertically place the area dividing plate little (perhaps can discharge old gas by exhaust fan earlier, the back is by the new cold air of supply fan inspiration) than the refrigerator sidewall.
This product can not established supply fan yet under the constant situation of other structure.Thereby can drain old air earlier by exhaust fan takes advantage of a situation by air inlet pipe suction cold air to form cabinet inner and outer air pressure difference.
The structure of main and auxiliary temperature controller all can adopt the temperature controller structure in the refrigerator.
Claims (2)
1, a kind of refrigerator, it is characterized in that this refrigerator is mainly by exhaust fan, compositions such as supply fan, main temperature controller, auxilliary temperature controller, blast pipe, air inlet pipe, row, supply fan and main and auxiliary temperature controller and power supply are cascaded, and arrange, air inlet pipe is respectively on the row of being enclosed within, the supply fan.
2,, it is characterized in that mainly forming by exhaust fan, main temperature controller, auxilliary temperature controller, blast pipe, air inlet pipe by the described refrigerator of claim 1.
