Description

Technical Field

[0001] This utility model relates to the field of ice-making technology, and specifically to a spray-type bullet ice maker. Background Technology

[0002] In the field of ice makers, ice cubes come in many shapes, including bullet ice, square ice, and round ice. Among them, bullet ice makers are characterized by high efficiency and speed because the evaporator is directly immersed in water to make ice.

[0003] For example, the invention patent with publication number CN103900313B discloses a small ice maker. This prior art uses the method of directly immersing the evaporator in water to make ice. However, this prior art has a complex structure and a large overall size; moreover, the bullet ice produced is milky white and opaque. The milky white part consists of tiny air bubbles. Because a certain amount of air is dissolved in the water, the gas released during the rapid ice-making process does not have time to escape and is frozen inside the ice block. After light refraction, it appears milky white. At the same time, because there are air bubbles inside the bullet ice, the bullet ice has a low density and melts easily.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0005] To address the problems of existing technologies, this utility model proposes a spray-type bullet ice maker that uses spray-type ice making instead of traditional immersion ice making. This results in a simpler and more reasonable structure, smaller overall size, and bullet ice that is transparent, dense, and resistant to melting.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows: A spray-type bullet ice maker includes a housing with a water tank assembly inside, the water tank assembly containing a water tank and a mounting part; a spray assembly fixed within the mounting part, the spray assembly including a spray bracket and a spray top plate, the spray top plate being fixed to the spray bracket, a spray ice-making chamber formed between the spray top plate and the spray bracket, a water outlet pipe on the spray bracket, and nozzles on the water outlet pipe, the nozzles being correspondingly arranged to the inner wall of the spray top plate; an ice-making and de-icing assembly including a bullet-shaped evaporator and an evaporation column, the upper end of the evaporation column being fixed to the bullet-shaped evaporator, and the lower end of the evaporation column passing through the spray top plate and located within the spray ice-making chamber; and a water pump assembly connected to the water tank and the water outlet pipe. This design uses a spray-type ice maker instead of the traditional immersion ice maker, resulting in a simpler and more reasonable structure and a smaller overall size. Specifically, during ice making, the water pump assembly circulates and draws water from the water tank and sends it to the outlet pipe. The water then circulates and sprays through nozzles on the outlet pipe onto the inner wall of the spray top plate. The water then flows down along the evaporation column, making the bullet ice produced transparent, dense, and resistant to melting.

[0007] According to the above scheme, an ice outlet is provided on one side of the spray ice-making chamber, and a curtain is movably installed on the ice outlet. With this configuration, by installing the curtain at the ice outlet, in its initial state, the curtain is vertically set under its own weight, which can be used to block water splashed during ice making, preventing water from splashing into the ice storage basket through the ice outlet and causing the ice in the ice storage basket to melt; when the ice detaches, the curtain can be opened under the weight and inertia of the ice, and it falls into the ice storage basket in the water tank.

[0008] According to the above scheme, the spray support is equipped with inclined ice guides, which are located below the evaporation column. With this configuration, when ice blocks detach, they fall onto the inclined ice guides, slide along them under gravity and inertia, and then fall into the ice storage basket inside the water tank after the curtain is opened.

[0009] According to the above scheme, an inclined water guide plate is provided on the inner wall of the water tank assembly between the water tank and the ice outlet. With this configuration, when water is circulated and sprayed onto the inner wall of the spray top plate through the nozzles on the water outlet pipe, the water that does not freeze (including the water that falls onto the inner wall of the spray top plate and the residual water that flows vertically down the evaporation column) will fall onto the spray support, and then return to the water tank for reuse after passing through the ice outlet and the inclined water guide plate.

[0010] According to the above scheme, a detachable ice storage basket is provided above the opening of the water tank. The ice storage basket has an ice inlet and a drain hole. The drain hole is set to correspond to the opening of the water tank, and the ice inlet is set to correspond to the door curtain. An ice full infrared sensor is provided on the inner wall of the water tank assembly above the ice inlet. With this configuration, when the ice in the ice storage basket melts, the water returns to the water tank through the drain hole for reuse. When the ice in the ice storage basket reaches the position of the ice full infrared sensor, the machine stops working and indicates that the ice is full.

[0011] According to the above scheme, the water tank is equipped with a high water level sensor and a low water level sensor. A drain hole corresponding to the water tank is located on the bottom of the tank, and a drain plug is provided on the drain hole for opening or closing it. With this configuration, when the water level in the tank reaches the low water level sensor position, the machine stops and water is replenished; when the water level in the tank reaches the high water level sensor position, water replenishment stops, and the machine can enter the ice-making state; when drainage is needed, all the water in the tank can be drained by simply pulling out the drain plug.

[0012] According to the above scheme, the water pump assembly includes a water pump and a silicone flexible water hose. The water pump is fixed to the outer wall of the bottom of the water tank, and the water inlet of the water pump is connected to the water tank. The water outlet of the water pump is connected to the silicone flexible water hose, and the silicone flexible water hose is connected to the outlet pipe. The water pump is equipped with a detection module for detecting the water pumping status. With this configuration, the water pump is located on the outer wall of the bottom of the water tank, which can more fully pump water out of the water tank and send it to the outlet pipe through the silicone flexible water hose. The detection module on the water pump will prompt and stop working when the machine is started after it starts pumping water. When the detection module detects that there is no water, it will pump water for ice making normally. That is, when the water pump is insufficient or cannot pump water, the machine stops working.

[0013] According to the above design, an insulating sponge is installed between the water tank assembly and the cabinet. This design serves to insulate the water, improves ice-making efficiency, and slows down ice melting.

[0014] According to the above scheme, the housing is equipped with a control panel, and the housing contains a refrigeration component and a power supply component. The refrigeration component includes a compressor and a condenser. The compressor is connected to the condenser via pipe one, the condenser is connected to the bullet-shaped evaporator via pipe two, and the bullet-shaped evaporator is connected to the compressor via pipe three. A hot gas reversing valve is installed on pipe three. With this configuration, during ice making, the compressor and condenser work together to deliver refrigerant to the bullet-shaped evaporator. The refrigerant absorbs heat, causing the surface temperature of the bullet-shaped evaporator to decrease, and this heat is conducted to the evaporation column, causing the ice flowing through the evaporation column to gradually freeze on the surface of the evaporation column. When the ice blocks have solidified to a preset thickness, the machine control system controls the hot gas reversing valve to open, and the hot gas flows in the opposite direction through the bullet-shaped evaporator for a certain period of time, and is conducted to the evaporation column, causing the ice blocks on the outer surface of the evaporation column to melt and detach due to heat.

[0015] According to the above scheme, the housing includes an upper cover assembly and an outer shell. The upper cover assembly includes a front cover and a rear cover. The rear cover is fixed to the outer shell and is located above the bullet-shaped evaporator. The front cover is movably installed on the rear cover and is located above the water tank. With this configuration, when ice needs to be removed, simply open the front cover for convenient operation.

[0016] The beneficial effects of this utility model are: This invention employs a spray-type ice-making system instead of the traditional immersion-type ice-making system, resulting in a simpler, more rational structure and a smaller overall size. Specifically, during ice-making, the water pump assembly circulates and extracts water from the water tank and sends it to the outlet pipe. The water is then sprayed through nozzles on the outlet pipe onto the inner wall of the spray top plate, and then flows down along the evaporation column, giving the bullet ice the characteristics of being transparent, dense, and not easily melted.

[0019] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 6As shown, the present invention discloses a spray-type bullet ice maker, comprising a housing, wherein a water tank assembly 5 is provided inside the housing, and the water tank assembly 5 contains a water tank 51 and a mounting part 52; and a spray assembly 3, which is fixed inside the mounting part 52. The spray assembly 3 includes a spray bracket 31 and a spray top plate 34, the spray top plate 34 being fixed to the spray bracket 31, and a spray ice-making chamber being formed between the spray top plate 34 and the spray bracket 31. The system includes: 1) a water outlet pipe 32 with nozzles 33 aligned with the inner wall of the spray top plate 34; 2) an ice-making and de-icing assembly 2 comprising a bullet-shaped evaporator 21 and an evaporation column 22, the upper end of which is fixed to the bullet-shaped evaporator 21, and the lower end of which passes through the spray top plate 34 and is located within the spray ice-making chamber; and 3) a water pump assembly 6 connected to the water tank 51 and the water outlet pipe 32. This configuration, using spray-type ice making instead of traditional immersion ice making, results in a simpler, more rational structure and a smaller overall size. Specifically, during ice making, the water pump assembly 6 circulates and pumps water from the water tank 51 to the water outlet pipe 32. The water then circulates through the nozzles 33 on the water outlet pipe 32 and sprays onto the inner wall of the spray top plate 34. The water then flows down the evaporation column 22, resulting in bullet ice that is transparent, dense, and resistant to melting.

[0021] Preferably, the sink assembly 5, the water tank 51 and the mounting part 52 are integrated into one structure. The water tank 51 is located at the bottom of the sink assembly 5, and a detachable ice storage basket is provided above the opening of the water tank 51. The mounting part 52 is located on one side above the water tank 51.

[0022] Preferably, there are multiple evaporation columns 22 arranged side by side, and multiple nozzles 33 arranged side by side, resulting in higher ice-making efficiency; and the nozzles 33 spray out in a spraying manner, so the spraying pressure is not very high, preventing water from splashing everywhere after hitting the spray top plate 34.

[0023] Furthermore, an ice outlet is provided on one side of the spray ice-making chamber, and a curtain 4 is movably installed on the ice outlet. With this arrangement, by setting the curtain 4 at the ice outlet, in its initial state, the curtain 4 is vertically set under its own weight, which can be used to block water splashed during ice making, preventing water from splashing into the ice storage basket through the ice outlet and causing the ice in the ice storage basket to melt; when the ice detaches, the curtain 4 can be opened under the weight and inertia of the ice and fall into the ice storage basket in the water tank 51.

[0024] Preferably, the curtain 4 is hinged to the ice outlet, and the curtain 4 is composed of multiple plastic sheets arranged side by side.

[0025] Furthermore, the spray support 31 is provided with an inclined ice guide 35, which is located below the evaporation column 22. With this configuration, when the ice blocks are detached, they fall onto the inclined ice guide 35, slide out along the inclined ice guide 35 under the influence of gravity and inertia, and fall into the ice storage basket in the water tank 51 after the door curtain 4 is opened.

[0026] Preferably, there are multiple inclined ice guides 35 arranged side by side, and the gap between adjacent inclined ice guides 35 is smaller than the volume of the ice block, so as to prevent the ice block from falling between adjacent inclined ice guides 35.

[0027] Furthermore, an inclined water guide plate 53 is provided on the inner wall of the water tank assembly 5 between the water tank 51 and the ice outlet. With this configuration, when water is circulated and sprayed onto the inner wall of the spray top plate 34 through the nozzles 33 on the water outlet pipe 32, the water that does not freeze (including the water that falls onto the inner wall of the spray top plate 34 and the residual water that flows vertically down along the evaporation column 22) will fall onto the spray support 31, and after passing through the ice outlet and the inclined water guide plate 53, it will return to the water tank 51 for reuse.

[0028] Furthermore, a detachable ice storage basket is provided above the opening of the water tank 51. The ice storage basket has an ice inlet and a drain hole. The drain hole is positioned corresponding to the opening of the water tank 51, and the ice inlet is positioned corresponding to the door curtain 4. An ice full infrared sensor 54 is provided on the inner wall of the water tank assembly 5 above the ice inlet. With this configuration, when the ice in the ice storage basket melts, the water returns to the water tank 51 through the drain hole for reuse. When the ice in the ice storage basket reaches the position of the ice full infrared sensor 54, the machine stops working and indicates that it is full.

[0029] Among them, there are two sets of ice-filled infrared sensing devices 54, which are symmetrically arranged on the inner walls of both sides of the water tank assembly 5.

[0030] Preferably, the machine stops working when the ice is full and can issue an alarm signal to remind the user to remove the ice and clean the ice storage basket.

[0031] Furthermore, the water tank 51 is equipped with a high water level sensor and a low water level sensor. A drain hole corresponding to the water tank 51 is located on the bottom of the tank, and a drain plug 91 is provided on the drain hole for opening or closing it. With this configuration, when the water level in the water tank 51 reaches the low water level sensor position, the machine stops and water is replenished; when the water level in the water tank 51 reaches the high water level sensor position, water replenishment stops, and the machine can enter the ice-making state; when drainage is needed, all the water in the water tank 51 can be drained by pulling out the drain plug 91.

[0032] Furthermore, the water pump assembly 6 includes a water pump 61 and a silicone flexible water pipe 62. The water pump 61 is fixed to the bottom outer wall of the water tank 51, and the inlet end of the water pump 61 is connected to the water tank 51. The outlet end of the water pump 61 is connected to the silicone flexible water pipe 62, and the silicone flexible water pipe 62 is connected to the outlet pipe 32. The water pump 61 is equipped with a detection module for detecting the water pumping status. With this configuration, the water pump 61, located on the bottom outer wall of the water tank 51, can more fully pump water out of the water tank 51 and deliver it to the outlet pipe 32 via the silicone flexible water pipe 62. The detection module on the water pump 61 will start pumping water when the machine is started. When the detection module detects a lack of water, it will prompt and stop working. When the detection module detects that there is water, it will pump water normally for ice making.

[0033] Preferably, the detection module can set a frequency limit for a load state. When the frequency falls below the set limit, the machine will issue a water shortage warning and stop working. That is, when the frequency falls below the set limit, if the water pump 61 cannot pump enough water or cannot pump any water, the machine will stop working.

[0034] Furthermore, an insulating sponge 8 is provided between the water tank assembly 5 and the box body. This arrangement serves to retain heat, resulting in better ice-making performance and slowing down the melting of ice.

[0035] Furthermore, the housing is equipped with a control panel, and the housing contains a refrigeration component 7 and a power supply component. The refrigeration component 7 includes a compressor 71 and a condenser 72. The compressor 71 is connected to the condenser 72 via a first pipe, the condenser 72 is connected to the bullet-shaped evaporator 21 via a second pipe, and the bullet-shaped evaporator 21 is connected to the compressor 71 via a third pipe. A hot gas reversing valve 73 is provided on the third pipe. With this configuration, during ice making, the compressor 71 and the condenser 72 work together to deliver refrigerant to the bullet-shaped evaporator 21. The refrigerant absorbs heat, causing the surface temperature of the bullet-shaped evaporator 21 to decrease, and this heat is conducted to the evaporation column 22, causing the ice flowing through the evaporation column 22 to gradually freeze on its surface. When the ice reaches a preset thickness, the machine control system controls the hot gas reversing valve 73 to open, and the hot gas flows in the opposite direction through the bullet-shaped evaporator 21 for a certain period of time, and is conducted to the evaporation column 22, causing the ice on the outer surface of the evaporation column 22 to melt and detach.

[0036] The control panel has multiple function buttons that can be used to control the water pump components and refrigeration system, making it easy to operate.

[0037] Preferably, a cooling fan is installed on the condenser 72 for better heat dissipation.

[0038] Furthermore, the housing includes an upper cover assembly 1 and an outer shell 9. The upper cover assembly 1 includes a front cover 11 and a rear cover 12. The rear cover 12 is fixed to the outer shell 9 and is located above the bullet-shaped evaporator 21. The front cover 11 is movably mounted on the rear cover 12 and is located above the water tank 51. This configuration allows for convenient operation by simply opening the front cover 11 when ice needs to be removed.

[0039] Preferably, the front cover 11 is hinged to the rear cover 12 in a flip-out manner.
