[0029] In the description of the present utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium.

[0030] like Figures 1 to 10 As shown, the refrigerator provided by the present invention includes a cabinet body 100 , a frost collecting box 200 and an air inlet pipe 300 .

[0031] The cabinet 100 is provided with a through hole, which penetrates the cabinet 100 to connect the inner and outer spaces of the cabinet 100 , and the air inlet pipe 300 is installed in the through hole.

[0032] The frost collecting box 200 is installed in the cabinet 100 and is used to reduce the humidity of the air entering the cabinet 100, ensure that the air entering the cabinet 100 is dry, and reduce frost therein.

[0033] The frost collecting box 200 includes a frost collecting chamber 201, condensing fins 202 located in the frost collecting chamber 201, and an air outlet 203 connecting the frost collecting chamber 201 and the internal space of the cabinet 100. The air inlet pipe 300 connects the external space of the cabinet 100 and the frost collecting chamber 201. The external air of the cabinet 100 enters the frost collecting chamber 201 from the air inlet pipe 300. The air inlet pipe 300 can be kept open or opened when needed to contact the low-temperature condensing fins 202 in the frost collecting chamber 201. The moisture in the external air condenses on the condensing fins 202 through condensation dehumidification. The dehumidified external air finally flows into the cabinet 100 through the air outlet 203.

[0034] The air outlet 203 is away from the air inlet pipe 300 , so that the air inlet position of the frost collecting chamber 201 is away from the air outlet position, so that the external air entering the frost collecting chamber 201 can fully contact the condensing fins 202 to achieve condensation and dehumidification.

[0035] Furthermore, a plurality of groups of condensing fins 202 are arranged at intervals in the frost collecting chamber 201, and the plurality of groups of condensing fins 202 form a serpentine flow channel in the frost collecting chamber 201, thereby increasing the flow path and flow time of external air in the frost collecting chamber 201, substantially reducing the humidity of air flowing into the cabinet 100, and reducing frost inside the cabinet 100.

[0036] Reference Figure 8 In this embodiment, the condensing fins 202 are arranged in the frost collecting chamber 201 at intervals along the first direction, and the dimension of the condensing fins 202 along the height direction is smaller than the dimension of the frost collecting chamber 201 along the height direction. Of the two adjacent groups of condensing fins 202, one group extends from the top of the frost collecting chamber 201 to the bottom of the frost collecting chamber 201, and the other group extends from the bottom of the frost collecting chamber 201 to the top of the frost collecting chamber 201. The air outlet 203 and the air inlet pipe 300 are located on both sides of the frost collecting box 200 along the first direction.

[0037] There are two adjacent groups of condensing fins 202, one group of which has a gap with the bottom of the frost collecting chamber 201, and the other group of which has a gap with the top of the frost collecting chamber 201. In this way, the external air entering the frost collecting chamber 201 from the air inlet pipe 300 first flows from top to bottom (from bottom to top) along the previous group of condensing fins 202, and then flows to the next group of condensing fins 202 through the gap between the previous group of condensing fins 202 and the bottom (top) of the frost collecting chamber 201, and flows from bottom to top (from top to bottom) along the next group of condensing fins 202, and so on and so forth until it flows into the cabinet 100 from the air outlet 203.

[0038] Preferably, the condensing fins 202 are parallel to each other and vertically arranged in the frost collecting chamber 201 along the height direction. The condensing fins 202 are made of metal materials such as aluminum and copper, preferably aluminum, which is cheap and light, has high heat exchange efficiency, and can effectively condense moisture in the air.

[0039] Of course, in other embodiments, the condensing fins 202 may also be spaced apart along the height direction, and the size of the condensing fins along the first direction is smaller than the size of the frost collecting chamber 201 along the first direction, and the external air entering the frost collecting chamber 201 flows back and forth along the first direction.

[0040] The frost collecting box 200 further includes a frost discharge port and a sealing cover 206 rotatably connected to the frost discharge port. When the main control board issues a defrosting prompt, the frost collecting box 200 located in the cabinet 100 is taken out, the sealing cover 206 is unscrewed, and water is poured into the frost collecting chamber 201 for flushing or poured out after the frost in the frost collecting chamber 201 melts. After defrosting is completed, the frost collecting box 200 is reinstalled in the cabinet 100. Preferably, the frost discharge port is provided at the top of the frost collecting box 200.

[0041] Furthermore, the refrigerator further includes a gravity sensor 400, a controller connected to the gravity sensor 400, and an alarm. The gravity sensor 400 is used to monitor the weight of the frost box 200. The gravity sensor 400 sends a weight signal to the main control board. As the frost increases, the weight of the frost box 200 increases. When the set weight is reached, the alarm issues a defrosting prompt. The gravity sensor 400 can be installed at the bottom of the frost box 200 or the inner bottom of the cabinet 100. The alarm can be a buzzer or a light alarm. In this embodiment, the set weight is 100g, which can be determined depending on the volume of the refrigerator.

The air inlet pipe 300 and the first connecting pipe 204 constitute an air inlet channel, and the air outlet 203 and the second connecting pipe 205 constitute an air outlet channel. The air outside the cabinet 100 enters the frost collecting chamber 201 through the air inlet channel, and the air after condensation and dehumidification flows into the cabinet 100 through the air outlet channel.

[0044] Furthermore, a fixed pipe 101 connected to the second connecting pipe 205 is also provided in the cabinet 100, and the fixed pipe 101 and the air intake pipe 300 have a first docking section extending upward along the height direction, and the first connecting pipe 204 and the second connecting pipe 205 have a second docking section extending downward along the height direction.

[0045] Specifically, the air inlet pipe 300 includes an air inlet section extending from the outside of the cabinet 100 to the inside of the cabinet 100, a first docking section located inside the cabinet 100, and a curved pipe section connecting the air inlet section and the first docking section; the fixed pipe 101 includes a first docking section and a curved pipe section connecting the first docking section and the inner wall of the cabinet 100, the first connecting pipe 204 and the second connecting pipe 205 have the same structure as the fixed pipe 101, the second docking section of the first connecting pipe 204 is inserted into the first docking section of the air inlet pipe 300, and the second docking section of the second connecting pipe 205 is inserted into the first docking section of the fixed pipe 101, thereby fixing the frost collecting box 200. The fixed pipe 101 and the air inlet pipe 300 serve as both a gas flow pipe and a fixing member.

[0046] Furthermore, the inner diameter of the air inlet pipe 300 is the same as the outer diameter of the first connecting pipe 204, and the second connecting section of the first connecting pipe 204 is inserted into the first connecting section of the air inlet pipe 300 to achieve a sealed connection; an exhaust hole is provided on the fixed pipe 101, and the exhaust hole is provided at the curved pipe section of the fixed pipe 101, and the condensed and dehumidified air finally flows into the cabinet 100 through the exhaust hole. In other embodiments, the first connecting section can also be used as an insertion section.

[0047] When installing the frost collecting box 200, the bottom of the frost collecting box 200 is abutted against the inner bottom of the cabinet 100, the insertion section of the first connecting pipe 204 is inserted into the docking section of the air inlet pipe 300, and the insertion section of the second connecting pipe 205 is inserted into the docking section of the fixed pipe 101, and the installation of the frost collecting box 200 is completed; when the frost collecting box 200 needs to be removed, the frost collecting box 200 is directly lifted up to separate the insertion section and the docking section.

[0048] Reference Figure 5 The frost collecting box 200 can also be installed in the cabinet 100 along a second direction perpendicular to the first direction. The frost collecting box 200 is provided with a first connecting pipe 204 and a second connecting pipe 205 on both sides along the second direction, thereby reducing the space occupied in the cabinet 100.
