The beneficial effects of the utility model are: adopt the refrigerator that the utility model provides, the different operation demand of refrigerator can be realized according to the frosting degree information that at least two described pressure sensors feed back, thus more accurately, reliably carry out defrost, affect the operation of refrigerator when avoiding the independent pressure sensor arranged to lose efficacy simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the evaporimeter of the utility model refrigerator.
Detailed description of the invention
Below with reference to embodiment shown in the drawings, the utility model is described in detail.But this embodiment does not limit the utility model, the structure that those of ordinary skill in the art makes according to this embodiment, method or conversion functionally are all included in protection domain of the present utility model.
Be illustrated in figure 1 the evaporation structure schematic diagram of the utility model refrigerator.Described refrigerator comprise evaporimeter 100, for give evaporimeter 100 defrost heater (not shown) and control described refrigerator run master control borad.Described refrigerator also comprises at least two pressure sensors arranged in gap with described evaporimeter 100 surface, and described pressure sensor, heater and master control borad communicate to connect.
Described refrigerator also comprises the supporting construction supporting fixing described evaporimeter 100, described supporting construction comprises longitudinally setting and is positioned at first gripper shoe 201 and second gripper shoe 202 at described evaporimeter 100 two ends, described first gripper shoe 201 and the opposing parallel setting of the second gripper shoe 202.Described evaporimeter 100 comprises the heat exchanger tube 101 and some fins 102 of vertical described heat exchanger tube 101 that horizontal buckling extends, and some described fins 102 to be equally arranged between described first gripper shoe 201 and the second gripper shoe 202 and to be parallel to described first gripper shoe 201 and the second gripper shoe 202.Described heater is located at the below of described evaporimeter 100 and is fixed in described first gripper shoe 201.
In the present embodiment, described refrigerator comprises the first pressure sensor 301 of below and the top being arranged at described evaporimeter 100 respectively and the second pressure sensor 302, first pressure sensor 301 is arranged in diagonal angle with the relative described evaporimeter 100 of the second pressure sensor 302.Particularly, described first pressure sensor 301 is arranged at the below of evaporimeter 100 and is oppositely arranged with the fin 102 closest to described first gripper shoe 201, and described second pressure sensor 302 is arranged at the top of evaporimeter 100 and is oppositely arranged with described second gripper shoe 202.Wherein, the first pressure sensor 301 is not oppositely arranged to damage described first pressure sensor 301 when effectively avoiding heating devices heat defrost with described first gripper shoe 201.
Preset the first clearance D 1 between the fin 102 that described first pressure sensor 301 is arranged corresponding thereto, preset the second clearance D 2 between described second pressure sensor 302 and described second gripper shoe 202, described first clearance D 1 is greater than described second clearance D 2.Notoriously, when refrigeration for refrigerator runs, the air flowed out from room, refrigerator storeroom upwards flows through the surface of evaporimeter 100 from the bottom of described evaporimeter 100, complete heat exchange, then be blown into the room, storeroom of refrigerator from the top of described evaporimeter 100.Make the surperficial frosting of evaporimeter 100 because the air flowing through evaporimeter 100 carries the aqueous vapor of food generation in room, storeroom, significantly, the air humidity below evaporimeter 100 is greater than the air humidity above evaporimeter.Described first pressure sensor 301 correspondence is arranged at the larger primary importance of evaporimeter 100 frosting degree, and sends defrost signal to master control borad when determining the thick D1 of reaching of the frost of the first pressure sensor 301 corresponding thereto between fin 102 of first position; Described second pressure sensor 302 correspondence is arranged at the less second place of evaporimeter 100 frosting degree, and sends defrost signal to master control borad when determining the thick D2 of reaching of frost between the second pressure sensor 302 of second position and the second gripper shoe 202.
For the user demand that refrigerator is different, if the room, storeroom of refrigerator is designed to need good moistening effect, when then master control borad is set to the defrost signal receiving the first pressure sensor 301 or the second pressure sensor 302 feedback, stop refrigeration for refrigerator, and control heater defrost is heated to evaporator surface.If reduce the energy consumption of refrigerator, reduce the defrost frequency, then, when master control borad can be set to the defrost signal simultaneously receiving first pressure sensor 301 or the second pressure sensor 302 feedback, carry out defrost.
Certainly, in other embodiment of the present utility model, described refrigerator is also provided with the sheet metal corresponding with described first pressure sensor 301 and the second pressure sensor 302.The material of described sheet metal and structure consistent with the fin 102 of described evaporimeter 100.By this, the installation of described first pressure sensor 301 and the second pressure sensor 302 arranges and departs from evaporimeter 100 and more convenient.
The beneficial effects of the utility model are: adopt the refrigerator that the utility model provides, the different operation demand of refrigerator can be realized according to the frosting degree information that at least two described pressure sensors feed back, thus more accurately, reliably carry out defrost, affect the operation of refrigerator when avoiding the independent pressure sensor arranged to lose efficacy simultaneously.
Be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present utility model; they are also not used to limit protection domain of the present utility model, all do not depart from the utility model skill equivalent implementations of doing of spirit or change all should be included within protection domain of the present utility model.
