Description

Technical Field

[0001] The invention belongs to the technical field of kitchen appliances, and in particular relates to an ice maker. Background Art

[0002] An ice maker is a refrigeration mechanical device that generates ice by cooling water through an evaporator with the refrigerant of the refrigeration system. It uses a refrigeration system and water as a carrier to make ice by passing it through a device under power-on state. Current household kitchen appliances include ice makers. When a household kitchen ice maker is used to defrost ice, the high-pressure hot air discharged from the compressor is generally directed to the evaporator through a reversing valve to replace the low-temperature liquid refrigerant. In this way, a layer of water film is formed between the ice cubes and the evaporator. This layer of water film causes the ice cubes to separate from the evaporator and fall freely into the ice storage tank below by gravity. When dirt is attached to the surface of the ice tray, the ice cubes are not easy to fall freely into the ice storage tank below by gravity. This method of defrosting takes a long time, and the ice tray with dirt attached to the surface not only affects the quality of ice making by the ice maker, but the attached dirt also affects the heat conduction, reducing the ice making efficiency of the ice maker.

By providing the hose 13, when the scraper 43 moves, the moving scraper 43 can drive the hose 13 to move synchronously through the second solenoid valve 15, so that the hose 13 can be firmly connected with the moving second solenoid valve 15 and the connecting pipe 12; An ice storage chamber 17 is provided in the ice maker housing 1. A drain valve 18 is connected to one side of the ice maker housing 1. The drain valve 18 is communicated with the collection chamber 73. The ice storage chamber 17 is provided directly below the fixed plate 61. The piston chamber 31 is communicated with a plurality of piston grooves 32. The piston rod 33 is in a T-shape. The bottom of the ice tray 22 is in an inclined shape. By providing the ice tray 22, the bottom of the ice tray 22 is in an inclined shape. The ice tray 22 in the ice tray 22 can slide downwards in an inclined manner. The water supply pipe 62 is connected with a plurality of transverse pipes 63, and the plurality of transverse pipes 63 are connected with a plurality of nozzles 64, and the plurality of nozzles 64 are respectively arranged in front of a plurality of ice trays 22; two limiting grooves 24 are provided on the front of the ice mold body 21, and the movable frame 42 is slidably connected in the limiting grooves 24. By setting the limiting grooves 24 and the movable frame 42, the limiting grooves 24 can limit the movement to the scraper 43 through the movable frame 42, so that the scraper 43 can move along the direction of the limiting grooves 24.

[0020] The working principle and use process of the present invention are as follows: when the ice maker in the household kitchen needs to be used, water is supplied through the water supply pipe 62, and the compressor 8 is controlled to work. The working compressor 8 passes the compressed refrigerant through the drying filter 9, the condenser 10, the expansion valve 11, the connecting pipe 12 and the first solenoid valve 14 into the evaporator 16. Since the evaporator 16 is immersed in the first cavity 23, and the evaporator 16 is provided with a plurality of spiral tubes wound in the first cavity 23, and the plurality of spiral tubes are wound outside each ice grid 22, when the liquid flowing in the water supply pipe 62 is sprayed into the plurality of ice grids 22 from the plurality of nozzles 64 through the plurality of transverse tubes 63, the heat of the water entering the ice grid 22 is conducted to the evaporator 16 through the ice mold body 21, so that the water in the ice grid 22 is gradually frozen; When it is necessary to defrost the ice in the ice tray 22, the four-way solenoid valve 20 is controlled to change the flow direction of the refrigerant, so that the refrigerant flowing through the drying filter 9 can flow into the connecting pipe 12 through the four-way solenoid valve 20 and the expansion valve 11, and part of the refrigerant moving into the connecting pipe 12 enters the evaporator 16 through the first solenoid valve 14, and the other part of the refrigerant enters the second cavity 44 through the hose 13 and the second solenoid valve 15. The heat of the refrigerant entering the evaporator 16 can be transferred to the ice tray 22 through the ice mold body 21. The ice cubes in the ice tray 22 are melted at the contact part with the ice mold body 21, and the cylinder 37 is controlled to extend. The extended cylinder 37 drives the piston plate 36 to move forward in the piston cavity 31, so that a positive pressure is generated in the plurality of piston grooves 32, so that the piston rod 33 in the piston groove 32 pushes the push plate 35 to move in the ice tray 22, so that the melted ice cubes are quickly pushed out of the ice tray 22 under the action of the forward moving push plate 35, and the pushed ice cubes slide onto the surface of the support frame 71 and then move along the surface into the ice storage cavity 17; Because the length of the piston rod 33 is designed according to the depth of the ice tray 22, when the moving piston rod 33 moves the ice cubes out of the ice tray 22 through the push plate 35, the front faces of the plurality of push plates 35 are in the same plane as the front face of the ice mold body 21, and in the process of moving the ice cubes out of the ice tray 22, the push plates 35 overlap with the inner wall of the ice tray 22, so that the push plates 35 can synchronously push out the dirt attached to the inner wall of the ice tray 22, and the pushed out dirt moves into the collection chamber 73 through the through groove 72 in the support frame 71, and controls the two multi-stage pneumatic telescopic rods 41 to contract, so that the contracted two multi-stage pneumatic telescopic rods 4 The scraper 43 is driven to move downward by the movable frame 42. The moving scraper 43 gradually contacts the front faces of the plurality of push plates 35 during the downward movement. The dirt attached to the front faces of the plurality of push plates 35 can be scraped off by the scraper 43 that moves downward and is heated. The scraper 43 is tightly fitted with the front face of the ice mold body 21 under the elastic force of the two second springs 52, so that the moving scraper 43 can be tightly fitted with the push plate 35 and the ice mold body 21, so that the scraper 43 can clean the dirt attached to the front face of the push plate 35 with high quality, and the cleaned dirt falls onto the support frame 71 and moves into the collection chamber 73 through the through slot 72; When the two multi-stage pneumatic telescopic rods 41 are retracted to the bottom, the two multi-stage pneumatic telescopic rods 41 drive the scraper 43 to move upward and automatically move to the initial position. At the same time, the four-way solenoid valve 20 re-introduces the refrigerant in the drying filter 9 into the condenser 10, and at the same time controls the second solenoid valve 15 to close.
