Background technology
Existing direct cooling refrigerator has refrigerating chamber and refrigerating chamber, and refrigerating chamber is fit to the temporary transient ready-to-eat food of placing; Freezer temperature is lower, and different from top to bottom intervals exist the bigger temperature difference in it, is used to place long-term no food; Yet, for not needing the non-again instant food of long-term storage, be placed in the refrigerating chamber and can rot, be placed on refrigerating chamber, need thaw after the taking-up, not only lose time and energy, but also can bring nutrition leak.For this reason, people begin to increase temperature-changing chamber and are used to place this based food on refrigerator, the patent No. is that the Chinese utility model patent of 02235998.X discloses a kind of refrigerating chamber that has, refrigerating chamber, the direct cooling refrigerator of temperature-changing chamber, the evaporator end of temperature-changing chamber passes through capillary, device for drying and filtering is connected with a port of export of a two-bit triplet magnetic valve, the entrance point of magnetic valve is connected with the port of export of condenser, the port of export of temperature-changing chamber evaporimeter is connected with the entrance point of freezer evaporator by a three-way pipe, another interface of three-way pipe passes through capillary, device for drying and filtering is connected with another outlet of magnetic valve, the port of export of freezer evaporator passes through liquid reservoir with after the evaporator series of refrigerating chamber is connected, the muffler assembly, the entrance point of compressor and condenser connects and composes closed circuit; Be provided with the temperature sensor that is connected with control device of refrigerator in the temperature-changing chamber, control the magnetic valve action, regulate the heat radiation of evaporimeter by the circulation path that changes cold-producing medium, thereby make the temperature of temperature-changing chamber remain on certain limit by it.The temperature control structure of the refrigerator temperature-changing chamber of this structure is very complicated, and under such low temperature environment the poor reliability of solenoid control, service life is short.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, provides to have the alternating temperature district in a kind of refrigerating chamber, and the alternating temperature district has the direct cooling refrigerator of simple temperature control equipment.
The utility model is achieved in that it comprises refrigerating chamber, and evaporimeter is set in the refrigerating chamber, and the refrigerating chamber bottom is provided with thermal insulation board, and the thermal insulation board below forms the alternating temperature district, and through hole is set on the thermal insulation board, and the through hole is provided with air door.
Above-mentioned air door has control device, and alternating temperature is provided with temperature sensor in the district, and it is connected with the control device of air door; Have in the alternating temperature district or be not with evaporimeter; The corresponding same fan refrigerator doors in alternating temperature district with refrigerating chamber; The refrigerating chamber top is provided with refrigerating chamber, and refrigerating chamber is provided with evaporimeter; Refrigerator evaporator is in parallel with freezing indoor evaporator or connect; The extent of alternating temperature in alternating temperature district is 0 ℃ to-12 ℃.
The utility model is separated out the alternating temperature district in the refrigerating chamber bottom with thermal insulation board, and thermal insulation board has on through hole and the through hole air door is set, and therefore can carry cold air in the alternating temperature district by air door; Because air door has control device, and connected temperature sensor is set in the alternating temperature district, therefore can control the switch of air door by the temperature of sensor, carry cold air to the alternating temperature district off and on, temperature is wherein remained within certain scope; Compared with prior art, the utility model is not that the temperature-changing chamber with evaporimeter and control device thereof is set separately, not to utilize valve regulated pipe for flowing of refrigerant road, adjusting evaporator area to wait the temperature of controlling temperature-changing chamber, but utilize air door and sensing control to control the temperature in alternating temperature district, because refrigerating chamber bottom self-temperature is just approaching with the required temperature of temperature-changing chamber, so the very easy realization of this control, and temperature controlling is simple in structure, the reliability height, long service life.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 along be A shown in Figure 1 to view.
The specific embodiment
The utility model overall structure as shown in Figure 1, it comprises refrigerating chamber 1, and refrigerating evaporator 2 is set in the refrigerating chamber 1, refrigerating chamber 1 bottom is provided with thermal insulation board 3, thermal insulation board 3 belows form alternating temperature district 4, and through hole 5 is set on the thermal insulation board 3, through hole 5 places are provided with air door 6; Air door 6 structures as shown in Figure 2, its setting should make when running through hole 5 that passes through of thermal insulation board 3 tops flow to alternating temperature district 4; Air door 6 has control device, and temperature sensor 7 is set in the alternating temperature district 4, and its control device with air door 6 is connected, no evaporimeter in the alternating temperature district 4 that is separated out; Alternating temperature district 4 and refrigerating chamber 1 corresponding same fan refrigerator doors.
Refrigerating chamber 1 top is provided with refrigerating chamber 8, and refrigerating chamber 8 is provided with refrigeration evaporator; Refrigeration evaporator and refrigerating evaporator 2 are in parallel or connect, and this is a prior art, does not repeat them here.
During actual the use, when the temperature in alternating temperature district 4 is higher than 0 when spending, sensor 7 is transferred to the control device of air door 6 with signal, and control device control air door 6 is opened, the cold air of thermal insulation board 3 tops descends the temperature in alternating temperature district 4 because gravity enters in the alternating temperature district 4 of below by through hole 5; Reach-12 when spending, sensor 7 is transferred to control device with signal, and air door 6 is closed.Because the temperature range of refrigerating chamber 1 bottom is original just approaching with the temperature of alternating temperature district 4 requirements, the therefore very easy realization of this control.
