Based on same utility model design, this application has still provided a refrigerator, and this refrigerator has adopted purifier, this purifier's specific structure refers to above-mentioned embodiment, because purifier has adopted the whole technical scheme of above-mentioned all embodiments, consequently has all beneficial effects that the technical scheme of above-mentioned embodiment brought at least, and the repeated description is no longer given here.
In some embodiments, the refrigerator includes: a case 100. The purification apparatus is provided in the cabinet 100, and the frame 10 of the purification apparatus is received and supported by the cabinet 100.
Fig. 5 is a schematic structural diagram of the box body of the present embodiment. In some embodiments, with reference to fig. 5, the refrigerator further includes: a drawer 50. The drawer 50 is slidably disposed in the box 100, so that the drawer 50 can enter and exit the box 100, thereby facilitating the placement and taking of food materials.
In some embodiments, the box 100 is opened with an opening and a receiving cavity, and the drawer 50 is inserted into the box 100 and slidably disposed in the receiving cavity, so as to facilitate the access of the drawer 50.
In some embodiments, in order to avoid interference with the movement of the drawer 50 from the inside of the cabinet 100, the frame 10 of the purification apparatus is disposed at the top of the cabinet 100, so that the drawer 50 can move in and out of the cabinet 100 smoothly. Of course, when the length of the drawer 50 is less than that of the box 100, the frame 10 of the purification apparatus can be disposed on the side wall of the box 100 away from the opening without interfering with the movement of the drawer 50.
In some embodiments, in order to facilitate the low-temperature air in the low-temperature compartment 60 to enter the frame 10, the air guide 70 of the purification apparatus is disposed through the sidewall of the box 100 to communicate with the low-temperature compartment 60, so that the low-temperature air in the low-temperature compartment 60 enters the frame 10 to cool the uv lamp assembly 30.
In some embodiments, in order to ensure that the drawer 50 can smoothly enter and exit the cabinet 100, a gap is formed between the top of the drawer 50 and the top of the cabinet 100, the air guide 70 is disposed through the sidewall of the cabinet 100 to communicate with the low-temperature chamber 60 through the gap, and the thickness of the air guide 70 is smaller than the gap, so as to prevent the air guide 70 from interfering with the entering and exiting of the drawer 50 in the cabinet 100.
