In the description of the present invention, it should be understood that the terms "upper", "lower", "first", "second", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1, in order to solve the problems pointed out in the background art, the technical solution provided by the present invention is that, a freezer adsorption type defrosting apparatus includes a freezer 6, a separator 1 is disposed above the freezer 6, a dryer 2 is disposed between the freezer 6 and the separator 1, a collection box 10 and an air blower 11 are disposed below the freezer 6, and the collection box 10 and the air blower 11 are hermetically connected by a pipeline; the inside of freezer 6 is equipped with adsorber 7, is located adsorber 7 top and is equipped with inlet valve 5, and is located the below of adsorber 7 and is equipped with outlet valve 9, and wherein, all end to end through the pipeline between separator 1, desicator 2, inlet valve 5, adsorber 7, outlet valve 9, the collecting box 10 forms a inclosed circulation passage.

Wherein: the adsorber 7 is composed of a frame and a filter screen, and the inside of the adsorber is filled with allochroic silica gel particles.

Through the technical scheme, the utility model discloses adsorber 7 is installed in freezer 6, can jointly use independent operation with inhaling first fan 8, also can install in the air inlet side of freezer 6 fan coil pipe, when the circulated air in freezer 6 flows through adsorber 7, vapor in the air is adsorbed by chameleon, because chameleon adsorption capacity is stronger, after air passes through adsorber 7, moisture basic silicone adsorbs, the reciprocating cycle, moisture in the air in freezer 6 is all adsorbed by silica gel, the drying system who comprises heater 3 and second fan 4 simultaneously, dry air flows through the evaporimeter of refrigerating system, just can not have frost formation, after chameleon adsorbs moisture, the colour becomes pink, through time control internal control, reach behind the adsorption time, open outlet valve 9, silica gel granule gravity flows to in collection box 10, after all flow out, close outlet valve 9, and (3) opening the inlet valve 5, enabling the regenerated silica gel to flow into the adsorber 7 by gravity, and continuously adsorbing the moisture in the refrigeration house 6.

Under the action of taking silica gel particles as an adsorption carrier, the humidity of air in the refrigeration house 6 is gradually reduced to be lower than the frost condensation temperature of the evaporator, no new frost is generated in the evaporator, the existing frost on the evaporator is gradually evaporated into dry air under the action of circulating air and is adsorbed by the silica gel again to form a mass transfer cycle, and finally, the evaporator is completely free of frost.

For further separation of water and vapor, the separator 1 is a centrifugal separator, silica gel particles flowing into the collector 7 are conveyed into the separator 1 under the action of the wind power of the blower 11, air is separated from the silica gel particles due to the centrifugal action, the wind is discharged from the upper opening of the separator 1, and the silica gel particles flow into the dryer 2 from the lower opening.

Further including being located the heater 3 of separator 1 below, the below of heater 3 still is equipped with first fan 4, and first fan 4 blows the air to heater 3, and hot-blast diffusion in to desicator 2 after the heating, under the hot-blast effect, the adsorbed moisture of silica gel evaporates once more, and the silica gel colour of desorption moisture becomes blue once more, and the silica gel after the dehydration is opened, is closed by the controller control that can control inlet valve 5 and outlet valve 9 and open and close, flows to in the adsorber 7 through inlet valve 5 this moment.

Further, including being located the second fan 8 in freezer 6, second fan 8 with adsorber 7 is on same water flat line, and the wind direction that is convenient for second fan 8 to produce owing to the level sets up and then is directed against adsorber 7 to be convenient for moisture in freezer 6 and adsorber 7 fully contact.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
