Description

Ice making mechanism and ice making machine Technical Field

[0001] The present invention relates to the technical field of ice making machines, in particular to an ice making mechanism and an ice making machine. Background Art

[0002] Currently, existing water-flowing ice makers on the market, such as Chinese Utility Model Patent Publication No. CN201093815Y, disclose a water-flowing ice maker comprising a housing, within which is mounted a water tank, an ice mold frame, and an ice-making system consisting of a compressor, a condenser, and an evaporator. The evaporator is positioned adjacent to the ice mold frame, and a water spray pipe is positioned above the ice mold frame, connected to a water pump via a water inlet pipe. The perforated ice-making grid in this prior art evaporator is tilted downward. During ice making, water is pumped from the water tank by a water pump through a water pipe to the water spray pipe, and then sprayed onto the ice mold frame. The water flows along the ice mold frame through the evaporator, where it is cooled and frozen. When ice making is complete, the refrigeration system reverses, allowing heat to enter the evaporator, causing the surface of the ice cubes to slightly melt. Gravity causes the ice cubes to slide out of the tilted perforated ice-making grid. However, this prior art can only produce square solid ice cubes, and cannot produce granular ice with holes in the middle that is suitable for chewing; and its water spray pipe is arranged above the ice mold frame, and water flows from the top porous ice making grid to the bottom porous ice making grid in sequence, resulting in low ice making efficiency; and because this prior art does not have an ice pushing structure, the ice removing efficiency is not high, which further leads to low ice making efficiency.

[0003] Therefore, there is still room for improvement and development in the existing technology. Technical Solutions

[0004] In view of the defects in the prior art, the present invention provides an ice-making mechanism and an ice-making machine, which can produce granular ice with a hole in the middle suitable for chewing, and the ice cubes will not be connected, and the ice-making efficiency is high.

[0005] In order to achieve the above object, the technical solutions applied by the present invention are as follows:

[0006] An ice-making mechanism includes an evaporator assembly, the evaporator assembly being provided with a plurality of perforated ice-making grids; a push plate slidably connected to the evaporator assembly, the push plate being provided with a plurality of push platforms, the push platforms being arranged corresponding to the perforated ice-making grids, the push platforms being provided with perforations, and the push plate being driven to move by a drive assembly; and a spray plate, the spray plate being arranged corresponding to the push plate, the spray plate being provided with a plurality of nozzles, the nozzles extending through the perforations in the push platforms into the perforated ice-making grids of the evaporator assembly. The present invention is configured as follows: in an initial state, the push plate is in close contact with the spray plate, the push platforms clearing the ice-making space of the perforated ice-making grids, and the nozzles on the spray plate extending through the perforations in the push platforms into the perforated ice-making grids of the evaporator assembly. During operation, the nozzles deliver water to the ice-making grids. When the refrigeration system is activated and the evaporator assembly is operating, ice produced in the perforated ice-making grids is produced by the nozzles into chewable granular ice with a hole in the middle. More specifically, the nozzles both spray water and form a through-hole in the middle of the ice cubes. When ice making is finished, the hot air valve of the refrigeration system is opened to rush hot air into the evaporator assembly, causing the surface of the ice cubes with holes adhering to the porous ice-making grid to melt slightly. The driving assembly drives the push plate to drive the push platform to extend into the porous ice-making grid to push out the made ice cubes with holes. After being pushed out, the driving assembly drives the push plate to return to the initial position to start the next round of ice making.

[0007] It should be noted that a plurality of porous ice-making grids are provided on the evaporator assembly; a plurality of push platforms corresponding to the plurality of porous ice-making grids are provided on the push plate, and the push platforms are provided with perforations; a plurality of nozzles corresponding to the plurality of push platforms are provided on the spray plate, and the plurality of nozzles can spray water to the plurality of porous ice-making grids respectively, which has higher ice-making efficiency, and after the ice is made, the ice is pushed by the push plate, and the ice-removing efficiency is higher, which can further improve the ice-making efficiency.

[0008] According to the above scheme, the evaporator assembly includes an evaporator, a front bracket, and a rear bracket. The front bracket is fixedly connected to the rear bracket. The evaporator is fixed between the front bracket and the rear bracket, and the two side surfaces of the evaporator are respectively attached to the front bracket and the rear bracket. The evaporator is provided with a plurality of porous ice-making grids. The front bracket is provided with a plurality of through-holes 1, which are arranged corresponding to one end of the porous ice-making grids. The rear bracket is provided with a plurality of through-holes 2, which are arranged corresponding to the other end of the porous ice-making grids. The push plate is slidably connected to the rear bracket, and the nozzles on the spray plate extend through the perforations on the push plate and the through-holes 2 on the rear bracket into the porous ice-making grids of the evaporator. The present invention is configured in this way: the evaporator assembly consists of the evaporator, the front bracket, and the rear bracket. The evaporator is clamped and fixed by the front bracket and the rear bracket. The two side surfaces of the evaporator are respectively attached to the front bracket and the rear bracket to provide heat preservation, reduce energy loss, and thereby improve ice making efficiency.

[0009] According to the above solution, the front bracket is made of a material with poor thermal conductivity. In the prior art, water flows from the top perforated ice tray to the bottom perforated ice tray, causing ice to form on the front surfaces of the ice trays. This results in ice cubes forming linked ice, resulting in poor ice-making performance. This arrangement of the present invention effectively prevents water from freezing on the front surface of the front bracket, preventing ice from forming linked ice between the perforated ice trays.

[0010] In practical applications, the front bracket is preferably made of plastic.

[0011] According to the above scheme, the evaporator is provided with multiple refrigerant channels, and the porous ice-making grid is staggered with the refrigerant channels. The multiple refrigerant channels are arranged symmetrically on two sides of the evaporator, and the multiple refrigerant channels are connected by copper pipes to form a refrigerant pipeline. The refrigerant pipeline has a refrigerant inlet and a refrigerant outlet at both ends. In this arrangement, when the refrigeration system is started and refrigerant flows through the refrigerant pipeline, the porous ice-making grid is staggered with the refrigerant channels, so that the porous ice-making grid is arranged between the multiple refrigerant channels. Compared with traditional bottom-mounted ice-making stations, more energy is transferred to the porous ice-making grid, and ice formation is faster. More specifically, by arranging the porous ice-making grid between the multiple refrigerant channels and designing the evaporator's energy-concentrating structure, the disadvantages of traditional evaporator structures, such as long ice formation time and large energy loss, are effectively improved. Compared with traditional integrated evaporators, the present invention uses less precious metals, has higher energy utilization, and produces more ice per unit time.

[0012] It should be noted that multiple refrigerant channels can be connected through copper tubes to form a refrigerant pipeline, so that a refrigerant inlet and a refrigerant outlet are provided at both ends of the refrigerant pipeline, which makes assembly more convenient.

[0013] According to the above solution, the nozzle extending into the porous ice-making grid has a closed end and a water spray hole on its upper side. This arrangement allows the sprayed water to first reach the upper half of the porous ice-making grid. During ice making, the upper half of the porous ice-making grid freezes some of the sprayed water, leaving unfrozen water flowing to the lower half of the porous ice-making grid to freeze. The unfrozen water then flows out the front of the porous ice-making grid and down along the front support. The perforated ice begins to freeze on the surface of the porous ice-making grid and then accumulates on the frozen surface. Due to the poor thermal conductivity of ice, freezing slows down as the ice thickness increases. Simultaneously, the nozzle continuously sprays water at a temperature higher than the ice temperature. By controlling the ice-making time, the ice does not freeze the nozzle until ice making is complete.

[0014] According to the above solution, the push plate is provided with a plurality of guide post holes, and the rear bracket is provided with a plurality of guide posts, which are slidably connected to the guide post holes. This arrangement of the present invention allows the push plate to move only forward and backward relative to the rear bracket, while ensuring that the plurality of push platforms on the push plate are always arranged in a one-to-one correspondence with the plurality of through holes on the rear bracket.

[0015] According to the above solution, the front bracket is provided with a plurality of studs, and the rear bracket is provided with a plurality of screw holes. The screw holes are arranged corresponding to the studs and are secured by screws. The front side of the front bracket is provided with an ice deflector arranged downwardly, and the ice deflector is provided with a plurality of water guide holes. This arrangement of the present invention facilitates assembly of the evaporator assembly. The ice deflector arranged downwardly on the front side of the front bracket allows ice pushed by the pusher to fall onto the ice deflector, where it is then directed to the ice storage basket, while the remaining water is directed through the water guide holes to the auxiliary water tank.

[0016] According to the above solution, the drive assembly includes a drive motor, a gear, and a rack. The rack is fixedly connected to the push plate. The output end of the drive motor is fixedly connected to the gear, and the gear and rack are meshed. The present invention is configured so that the drive motor drives the gear to rotate forward and reverse, and the gear and rack cooperate to drive the push plate to move forward and backward.

[0017] The above solution also includes a spray plate cover, which is fixedly connected to the spray plate. A water storage chamber is formed between the spray plate cover and the spray plate, and the spray plate cover is provided with a water inlet. The present invention is configured such that during ice making, water enters the water storage chamber through the water inlet and is then delivered to the porous ice making grid through the nozzles on the spray plate. When ice making is complete, the water inlet stops flowing, and the water in the water storage chamber flows back through the water inlet.

[0018] An ice maker comprises a main unit, wherein the main unit is provided with a main water tank, a first water pump, a secondary water tank, a second water pump, a condenser, a compressor, an ice storage basket and the above-mentioned ice making mechanism, and a control panel is provided on the main unit; the first water outlet of the main water tank is connected to the water inlet of the first water pump through a water pipe, the water outlet of the first water pump is connected to the water inlet of the secondary water tank through a water pipe, the second water outlet of the secondary water tank is connected to the water inlet of the second water pump through a water pipe, and the water outlet of the second water pump is connected to the water inlet on the spray plate cover through the water pipe and the pump water port. The present invention is designed as follows: during operation, water pump 1 pumps water from outlet 1 of the main water tank to the water inlet of the auxiliary water tank, where it enters the auxiliary water tank. When the auxiliary water tank is full of water, water pump 2 starts to operate, pumping water from the auxiliary water tank from outlet 2 to the pump inlet. The pump inlet is connected to the water inlet on the spray plate cover through a water pipe, and water enters the water storage chamber. The nozzle of the spray plate transports the water in the water storage chamber to the porous ice making grid to start ice making. During the ice making process, unfrozen water flows along the surface of the front bracket to the ice guide plate, and then flows back to the auxiliary water tank through the water guide holes of the ice guide plate. After ice making is completed, the perforated ice cubes in the porous ice making grid are pushed out by the push plate on the push plate, and the perforated ice cubes slide along the ice guide plate into the ice storage basket. The compressor and condenser are components of the refrigeration system, transporting refrigerant to the refrigerant pipeline. The control panel can control the machine's startup and shutdown.

[0019] It should be noted that the dual water tank and dual water pump structure has a better water storage effect and a longer ice-making endurance. When the main water tank is short of water and needs to be replenished, the auxiliary water tank can still replenish water for the water storage chamber, and the machine will not stop working due to lack of water.

[0020] In actual application, the auxiliary water tank is located directly below the ice-making mechanism, the ice storage basket is located in front and below the ice-making mechanism, and the main water tank is located below the ice storage basket. Beneficial effects

[0021] Beneficial effects of the present invention:

[0022] The present invention is configured such that the nozzle on the spray plate extends through the through-hole on the push platform into the porous ice-making grid of the evaporator assembly. The nozzle not only sprays water, but also forms a through-hole in the middle of the ice cube. As a result, the ice made in the porous ice-making grid is made into granular ice with a hole in the middle that is suitable for chewing under the action of the nozzle. In addition, a plurality of porous ice-making grids are provided on the evaporator assembly, so the ice-making efficiency is higher. After the ice is made, the push plate is used to push the ice, so the ice-removing efficiency is higher, which can further improve the ice-making efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Best Mode for Carrying Out the Invention

[0036] The technical solution of the present invention is described below with reference to the accompanying drawings and embodiments.

[0037] As shown in Figures 1 to 11, an ice-making mechanism described in the present invention includes an evaporator assembly, which is provided with a plurality of porous ice-making grids 101; a push plate 4, which is slidably connected to the evaporator assembly, and is provided with a plurality of push platforms 402, which are arranged corresponding to the porous ice-making grids 101, and are provided with through holes 403. The push plate 4 is driven to move by a driving assembly; a spray plate 5, which is arranged corresponding to the push plate 4, and is provided with a plurality of nozzles 501. The nozzles 501 pass through the through holes 403 on the push platforms 402 and extend into the porous ice-making grids 101 of the evaporator assembly. The present invention is configured as follows: in the initial state, the push plate 4 is in close contact with the spray plate 5, and the push platform 402 avoids the ice-making space of the porous ice-making grid 101. The nozzle 501 on the spray plate 5 passes through the through-hole 403 on the push platform 402 and extends into the porous ice-making grid 101 of the evaporator assembly. During operation, the nozzle 501 delivers water to the ice-making grid 101, the refrigeration system is started, and the evaporator assembly operates. The ice made in the porous ice-making grid 101 is made into chewable granular ice with a hole in the middle (i.e., perforated ice cubes 10) under the action of the nozzle 501. More specifically, the nozzle 501 not only sprays water, but also forms a through hole in the middle of the ice cube. When ice making is finished, the hot air valve of the refrigeration system is opened to rush hot air into the evaporator assembly, so that the surface of the perforated ice cube 10 adhering to the porous ice-making grid 101 is slightly melted, and the driving assembly drives the push plate 4 to drive the push platform 402 to extend into the porous ice-making grid 101 to push out the made perforated ice cube 10. After being pushed out, the driving assembly drives the push plate 4 to return to the initial position to start the next round of ice making.

[0038] It should be noted that a plurality of porous ice-making grids 101 are provided on the evaporator assembly; a plurality of push platforms 402 corresponding one-to-one to the plurality of porous ice-making grids 101 are provided on the push plate 4, and a perforation 403 is provided on the push platform 402; a plurality of nozzles 501 corresponding one-to-one to the plurality of push platforms 402 are provided on the spray plate 5, and the plurality of nozzles 501 can spray water to the plurality of porous ice-making grids 101 respectively, so that the ice-making efficiency is higher, and after the ice is made, the ice is pushed by the push plate 4, and the ice-removing efficiency is higher, which can further improve the ice-making efficiency.

[0039] In this embodiment, the evaporator assembly includes an evaporator 1, a front bracket 2 and a rear bracket 3. The front bracket 2 is fixedly connected to the rear bracket 3. The evaporator 1 is fixed between the front bracket 2 and the rear bracket 3, and the two side surfaces of the evaporator 1 are respectively attached to the front bracket 2 and the rear bracket 3; the evaporator 1 is provided with a plurality of porous ice-making grids 101, and the front bracket 2 is provided with a plurality of through holes 202, and the through holes 202 are corresponding to one end of the porous ice-making grid 101; the rear bracket 3 is provided with a plurality of through holes 302, and the through holes 302 are corresponding to the other end of the porous ice-making grid 101; the push plate 4 is slidably connected to the rear bracket 3, and the nozzle 501 on the spray plate 5 passes through the through hole 403 on the push platform 402 and the through hole 2 302 on the rear bracket 3 and extends into the porous ice-making grid 101 of the evaporator 1. The present invention is configured such that the evaporator assembly consists of an evaporator 1, a front bracket 2 and a rear bracket 3. The evaporator 1 is clamped and fixed by the front bracket 2 and the rear bracket 3, and the two side surfaces of the evaporator 1 are respectively attached to the front bracket 2 and the rear bracket 3 to play a role in heat preservation, reduce energy loss, and thus improve ice making efficiency.

[0040] In this embodiment, the front support 2 is made of a material with poor thermal conductivity. In the prior art, water flows from the top perforated ice tray to the bottom perforated ice tray, causing ice to form on the front surfaces of the ice trays. This results in ice cubes forming a continuous ice layer, resulting in poor ice-making performance. This arrangement of the present invention effectively prevents water from freezing on the front surface of the front support 2, preventing ice from forming a continuous ice layer between the perforated ice cubes 10 produced.

[0041] In practical applications, the front bracket 2 is preferably made of plastic.

[0042] In this embodiment, a plurality of refrigerant channels 102 are provided in the evaporator 1, and the porous ice cube tray 101 is staggered with the refrigerant channels 102; the plurality of refrigerant channels 102 are arranged symmetrically on two sides of the evaporator 1, and the plurality of refrigerant channels 102 are connected by copper tubes to form a refrigerant pipe 103, and a refrigerant inlet and a refrigerant outlet are provided at both ends of the refrigerant pipe 103. The present invention is configured such that when the refrigeration system is started, the refrigerant flows through the refrigerant pipe 103. Since the porous ice-making grid 101 and the refrigerant channel 102 are staggered, the porous ice-making grid 101 is arranged between multiple refrigerant channels 102. Compared with the traditional bottom-mounted ice-making station, more energy is transmitted to the porous ice-making grid 101, and the ice-forming speed is faster; more specifically, by arranging the porous ice-making grid 101 between multiple refrigerant channels 102 and the energy-gathering structure design of the evaporator 1, the disadvantages of the traditional evaporator structure, such as long ice-forming time and large energy loss, are effectively improved. Compared with the traditional integrated evaporator, the amount of precious metal used is less, the energy utilization rate is higher, and the ice-making amount per unit time is more.

[0043] It should be noted that a plurality of refrigerant channels 102 can be connected through copper tubes to form a refrigerant pipe 103 , so that a refrigerant inlet and a refrigerant outlet are provided at both ends of the refrigerant pipe 103 , which makes assembly more convenient.

[0044] In this embodiment, the end of the nozzle 501 extending into the porous ice making tray 101 is closed, and a water spray hole 502 is provided on the upper side thereof. The present invention is configured such that the end of the nozzle 501 is closed and a water spray hole 502 is provided on its upper side, so that the sprayed water can be sprayed to the upper half of the porous ice-making grid 101 first. When making ice, the upper half of the porous ice-making grid 101 will freeze a part of the sprayed water into ice, and the unfrozen water will flow to the lower half of the porous ice-making grid 101 to freeze. At this time, the unfrozen water will flow out from the front of the porous ice-making grid 101 and flow downward along the front bracket 2. The perforated ice cubes 10 first begin to freeze from the surface of the porous ice-making grid 101 and then continue to accumulate on the frozen ice surface. Due to the poor thermal conductivity of ice, the freezing will become slower and slower when the ice thickness increases. At the same time, the nozzle 501 continuously sprays water with a temperature higher than the ice cube temperature. By controlling the ice-making time, the ice cubes will not freeze the nozzle 501 until the ice-making is completed.

[0045] In this embodiment, the push plate 4 is provided with a plurality of guide post holes 401, and the rear bracket 3 is provided with a plurality of guide posts 301, which are slidably connected to the guide post holes 401. This arrangement of the present invention allows the push plate 4 to move only forward and backward relative to the rear bracket 3, while also ensuring that the plurality of push platforms 402 on the push plate 4 are always arranged in a one-to-one correspondence with the plurality of through holes 302 on the rear bracket 3.

[0046] In this embodiment, the front bracket 2 is provided with a plurality of studs 203, and the rear bracket 3 is provided with a plurality of screw holes 303. The screw holes 303 are correspondingly located with the studs 203 and are secured by screws. An ice deflector 201 is provided on the front side of the front bracket 2, which is tilted downward. The ice deflector 201 is provided with a plurality of water guide holes. This arrangement of the present invention facilitates assembly of the evaporator assembly. The tilted downward ice deflector 201 provided on the front side of the front bracket 2 allows the pusher 402 to push ice that falls onto the ice deflector 201 and guides it into the ice storage basket 19. Any remaining water can be directed through the water guide holes into the auxiliary water tank 15.

[0047] In this embodiment, the drive assembly includes a drive motor 7, a gear 8, and a rack 9. The rack 9 is fixedly connected to the push plate 4. The output end of the drive motor 7 is fixedly connected to the gear 8, and the gear 8 is meshed with the rack 9. In the present invention, the drive motor 7 drives the gear 8 to rotate forward and reverse, and the gear 8 and rack 9 cooperate to drive the push plate 4 to move forward and backward.

[0048] This embodiment also includes a spray plate cover 6, which is fixedly connected to the spray plate 5. A water storage chamber 20 is formed between the spray plate cover 6 and the spray plate 5. The spray plate cover 6 is provided with a water inlet 601. During ice making, water enters the water storage chamber 20 through the water inlet 601 and is then delivered to the porous ice making grid 101 through the nozzle 501 on the spray plate 5. When ice making is complete, the water inlet 601 stops flowing, and the water in the water storage chamber 20 flows back through the water inlet 601.

[0049] An ice maker includes a main unit 12, wherein the main unit 12 is provided with a main water tank 13, a water pump 14, an auxiliary water tank 15, a water pump 2 16, a condenser 17, a compressor 18, an ice storage basket 19 and the above-mentioned ice making mechanism, and a control panel 11 is provided on the main unit 12; the water outlet 131 of the main water tank 13 is connected to the water inlet end of the water pump 14 through a water pipe, the water outlet end of the water pump 14 is connected to the water inlet 151 of the auxiliary water tank 15 through a water pipe, the water outlet 2 152 of the auxiliary water tank 15 is connected to the water inlet end of the water pump 2 16 through a water pipe, and the water outlet end of the water pump 2 16 is connected to the water inlet 601 on the spray plate cover 6 through a water pipe and a pumping port 153. The present invention is configured as follows: when working, the water pump 14 pumps water from the outlet 131 of the main water tank 13 to the water inlet 151 of the auxiliary water tank 15, and then the water enters the auxiliary water tank 15. When the auxiliary water tank 15 is full of water, the water pump 2 16 starts working and pumps the water in the auxiliary water tank 15 from the outlet 152 to the pump port 153. The pump port 153 is connected to the water inlet 601 on the spray plate cover 6 through a water pipe, and the water enters the water storage chamber 20. The nozzle 501 of the spray plate 5 delivers water from the water storage chamber 20 to the perforated ice cube tray 101 to begin ice making. During the ice-making process, unfrozen water flows along the surface of the front bracket 2 to the ice guide plate 201, and then flows back into the auxiliary water tank 15 through the water guide holes of the ice guide plate 201. After ice making is completed, the perforated ice cubes 10 in the perforated ice cube tray 101 are pushed out by the pusher 402 on the push plate 4, and the perforated ice cubes 10 slide along the ice guide plate 201 into the ice storage basket 19. The compressor 18 and condenser 17 are components of the refrigeration system, supplying refrigerant to the refrigerant pipe 103. The control panel 11 can control the machine's power on and off.

[0050] It should be noted that the use of a dual water tank and dual water pump structure has a better water storage effect and a longer ice-making endurance. When the main water tank 13 is short of water and needs to be replenished, the auxiliary water tank 15 can still replenish water for the water storage chamber 20, and the machine will not stop working due to lack of water.

[0051] In actual application, the auxiliary water tank 15 is located directly below the ice-making mechanism, the ice storage basket 19 is located in front and below the ice-making mechanism, and the main water tank 13 is located below the ice storage basket 19 .

The above-mentioned specific implementation methods are merely illustrative and not restrictive.
