The specific embodiment
Describe the example of the utility model below in detail, the example of said example is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Be exemplary through the example that is described with reference to the drawings below, only be used to explain the utility model, and can not be interpreted as restriction the utility model.
In the description of the utility model; It will be appreciated that; The orientation of indications such as term " " center ", " vertically ", " laterally ", " on ", D score, " preceding ", " back ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", " outward " or position relation are for based on orientation shown in the drawings or position relation; only be to describe with simplifying for the ease of describing the utility model; rather than the device or the element of indication or hint indication must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction to the utility model.
In addition, term " first ", " second " only are used to describe purpose, and can not be interpreted as indication or hint relative importance.
In the description of the utility model, need to prove that only if clear and definite regulation and qualification are arranged in addition, term " installation ", " linking to each other ", " connection " should be done broad understanding, for example, can be to be fixedly connected, connect integratedly, also can be to removably connect; Can be mechanical connection or electrical connection, also can be the connection of two element internals; Can be directly to link to each other, also can link to each other indirectly, for those of ordinary skill in the art, can understand the concrete implication of above-mentioned term as the case may be through intermediary.
At first be described in detail with reference to the attached drawings refrigerator below according to the example of the utility model.
Fig. 1 shows the refrigerator according to an example of the utility model, and said refrigerator comprises: casing 10, refrigerating-chamber door body and refrigerating chamber door body (not shown).
Have refrigerating chamber and refrigerating chamber in the casing 10, said refrigerating-chamber door body and refrigerating chamber door body are pivotably mounted on respectively on the casing 10 opening and closing said refrigerating chamber and refrigerating chamber respectively,
Wherein, Air channel cover plate 20 is installed in the said refrigerating chamber; Air channel cover plate 20 is provided with return air inlet 21 and air outlet 22 between the inner bag 11 of air channel cover plate 20 and said refrigerating chamber, to form the air channel, is provided with liquid storaging device 30 and liquid storaging device 30 tops in the said air channel and is provided with refrigeration fan 40.
Thus, according to the refrigerator of the utility model example, because the liquid storaging device 30 that in refrigerator air duct, is provided with can be collected the defrost water in the refrigerator; And under the effect of refrigeration fan 40, defrost water is become steam along with kind of refrigeration cycle is brought refrigerating chamber into, effectively avoided defrost and the refrigerating chamber water loss that causes, improved moistening effect; Take away cold thereby effectively reduce colder water, strengthen the fresh-keeping effect of refrigerator, reduce the loss of nutrition; Not taint of odour of food between each chamber has improved the heat exchange efficiency of refrigerator, thereby has reduced the thermic load of refrigerating chamber; Effectively save the consumption of electric energy, reduced the energy consumption of refrigerator.
In one example, return air inlet 21 is positioned at air outlet 22 tops, and liquid storaging device 30 is between return air inlet 21 and air outlet 22.Thus; The defrost water that in liquid storaging device 30, stores can quicken evaporation under the air-flow effect of return air inlet 21; And under the effect of refrigeration fan 40; Along with kind of refrigeration cycle gets in the refrigerating chamber from air outlet 22, avoided the refrigerating chamber water loss that causes owing to defrost, improved the humidity of refrigerating chamber.
About liquid storaging device 30, it will be appreciated that the position of liquid storaging device 30 in the air channel do not have particular restriction, as long as between return air inlet 21 and air outlet 22, and can play the effect that stores defrost water and get final product.In one example, liquid storaging device 30 can be located on the inner bag 11 of refrigerating chamber, and advantageously, liquid storaging device 30 is one-body molded with inner bag 11; In one example, liquid storaging device 30 can be located on the air channel cover plate 20 of refrigerating chamber, and advantageously, liquid storaging device 30 is one-body molded with air channel cover plate 20.Thus, under the prerequisite of the water storage effect that does not influence liquid storaging device 30, can improve installation flexibility, and integrated structure can reduce whole preparation cost.
In one example, liquid storaging device 30 is " √ " type baffle plate.Thus, the liquid storaging device 30 of this structure can effectively be stored defrost water, and " √ " type opening has guaranteed that the liquid in the liquid storaging device 30 have bigger evaporation surface, evaporation rate that can accelerating liquid, and " √ " type is simple in structure, and preparation is convenient.
As shown in Figure 2; In one example; Be separately installed with refrigeration evaporator 50 and refrigerating evaporator 60 in said refrigerating chamber and the refrigerating chamber; Be provided with magnetic valve 70 in the said refrigerator, magnetic valve 70 links to each other with the input of refrigeration evaporator 50 and the input of refrigerating evaporator 60 with freezing capillary 72 through refrigeration capillary 71 respectively, and the output of refrigeration evaporator 50 links to each other with the input of refrigerating evaporator 60 and the output of refrigerating evaporator 60 is connected with compressor 80.Thus; Under the effect of magnetic valve 70, cold-producing medium gets into refrigeration evaporator 50 and refrigerating evaporator 60 through refrigeration capillary 71 and freezing capillary 72 respectively behind magnetic valve 70; Magnetic valve 70 can be controlled two switchings capillaceous, and then controls the work of two evaporimeters.When refrigerating chamber need freeze, switch through magnetic valve 70, lead to refrigeration capillary 71 conductings of refrigeration evaporator 50, then refrigerating chamber begins refrigeration; When refrigerating chamber requires to close, switch through magnetic valve 70, the refrigeration capillary 71 that leads to refrigeration evaporator 50 is closed, and then refrigerating chamber stops refrigeration.
As shown in Figure 3, in one example, refrigeration sensor 12 and defrosting sensor 13 are installed in the said refrigerating chamber.Thus, under the effect of refrigeration sensor 12 and defrosting sensor 13,, can realize that the humidity of refrigerating chamber remains on higher level through the switching of dual sensor temperature detection, control magnetic valve 70, the rotating speed of adjustment refrigeration fan 40.When refrigerating chamber freezed, the rotating speed of refrigeration fan 40 was r0, and an indoor air is under the effect of refrigeration fan 40; Carry out heat exchange with refrigeration evaporator 50; In exchange process, a part of steam can condense into frost attached to inside container back, and the humidity of a chamber can reduce; When refrigerating chamber does not freeze,, make that the air in the refrigerating chamber continues circulation through the rotating speed of continuous adjustment refrigeration fan 40; Because the indoor air themperature of refrigerator is between 1~6 ℃; The frosting of inside container back is constantly melted and is become steam before making, and is stored on the liquid storaging device 30, again under the effect of refrigeration fan 40; With the evaporation of the water in the liquid storaging device 30 and bring back in the refrigerating chamber, guarantee the humidity of refrigerating chamber.
