Description

Technical Field

[0001] This invention relates to the field of ice-making equipment technology, and more particularly to a household ice-making device. Background Technology

[0002] Ice-making equipment is a device used to produce ice cubes. It works by cooling water and freezing it into ice, and is widely used in the catering industry, hotels, supermarkets, seafood markets, and other places. With the popularization of technology, household ice-making equipment is also gradually becoming more popular.

[0003] Current household ice-making equipment still uses the same ice-making principle as medium and large-sized ice makers. These devices typically have a refrigeration system and an ice storage system. The refrigeration system uses a compressor and evaporator to cool water. Once the water reaches a certain temperature, it freezes into ice. The compressor then sprays a high-temperature medium into the evaporator, causing the ice to melt and fall into the ice storage system. The evaporators in current household ice-making equipment are usually trough-shaped structures with continuously distributed ice troughs. The resulting ice is typically a single, monolithic block, with multiple small ice blocks bonded together. Because the evaporators are usually vertically oriented, the ice blocks generally fall vertically as well. This vertical sliding motion usually maintains the integrity of the structure, often requiring manual breaking of the monolithic ice block for easy access. This is inconvenient, therefore, there is a need to improve the way the ice blocks slide down, enhancing ease of use. Summary of the Invention

The ice guide plate protrudes towards the ice baffle plate, and a water guide groove is formed between two adjacent ice guide plates. The outer edge of the support platform is provided with a water guide slope, which slopes downward and communicates with the water guide groove. The middle part of the ice baffle platform is provided with a water outlet, which communicates with the water storage space.

[0010] As an improvement to the above solution, the water circulation assembly further includes a pump, which is located at the bottom of the receiving cavity or the ice-making cavity. The water inlet of the pump is connected to the water storage space, and the water outlet of the pump is connected to the spray pipe. The spray pipe is located above the ice-making plate and spans across both sides of the ice-making plate. The nozzle of the spray pipe faces downward or diagonally downward.

[0011] As an improvement to the above solution, the ice storage basket is provided with a handle hole at the top, the handle hole is provided on both sides of the ice storage basket, and the side wall and bottom of the ice storage basket are provided with multiple baffle holes, the baffle holes are connected to the water storage space.

[0017] Implementing this invention has the following beneficial effects:

[0018] This invention relates to a household ice-making device comprising a housing, an inner liner assembly, a water circulation assembly, a refrigeration assembly, a spray assembly, and an ice-making assembly mounted on the inner liner assembly. The ice-making assembly includes an ice-making plate vertically placed on an ice-making tank. Multiple ice trays are arranged on the side of the ice-making plate near the ice storage basket. During ice making, each ice tray forms a small ice block, and multiple small ice blocks combine to form a large ice block. To increase the impact force when the large ice block falls, an ice guide plate is provided at the bottom of the ice-making tank, with the upper edge of the ice guide plate extending from the ice-making plate. The ice storage basket is tilted downwards to guide the ice block to slide downwards during melting. An ice baffle is installed at the downward angle, with a gap between the ice baffle and the ice guide. When a large ice block slides down, its lower part gets stuck in the gap, making the ice baffle a positioning point for the bottom of the ice block. At this time, the large ice block will roll downwards due to its sliding inertia, which increases the impact force on the large ice block when it falls, improving the ice-breaking effect when the large ice block falls into the ice storage basket, making it easier for users to directly take out small ice blocks.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0024] See Figure 1 This invention discloses a household ice-making device, including a housing 1, an inner liner assembly 2, a water circulation assembly 3, a refrigeration assembly 4, a spray assembly 5, and an ice-making assembly 6 disposed on the inner liner assembly 2. The inner liner assembly 2 is used for storing water and ice. The water circulation assembly 3 is used for driving water circulation. The spray assembly 5 and the ice-making assembly 6 are used for making ice. The housing 1 includes a receiving cavity 11 and an ice-making cavity 12. The ice-making cavity 12 is disposed on the side of the receiving cavity 11. The inner liner assembly 2 is disposed in the receiving cavity 11. The water circulation assembly 3 includes a water tank 31. The water tank 31, the refrigeration assembly 4, and the ice-making assembly 6 are disposed in the ice-making cavity 12.

[0025] The inner liner assembly 2 includes an inner liner box 21 and an ice storage basket 22 disposed within the inner liner box 21. An ice-making trough 23 is provided in the inner liner box 21 near the ice-making chamber 12. The ice-making assembly 6 includes an ice-making plate 61 vertically placed on the ice-making trough 23. The ice-making plate 61 can form ice blocks during heat exchange and cooling. Multiple ice trays 611 are provided in the ice-making plate 61 near the ice storage basket 22, allowing ice blocks to "grow" within the ice trays 611. The spray assembly 5 includes a spray pipe 51. The spray pipe 51 is disposed in… Above the ice-making plate 61, during use, the spray pipe 51 sprays water downwards, causing the water to flow through the opening of the ice tray 611. The ice-making assembly 6 keeps the temperature of the ice-making plate 61 below 0°C, causing the water to freeze at the opening of the ice tray 611. The resulting ice gradually fills the entire ice tray 611, forming small ice blocks. Multiple small ice blocks stick together to form large ice blocks. When the ice-making plate 61 is heated, under the influence of heat, the ice blocks in the ice tray 611 detach from the ice tray 611 and begin to fall into the ice storage basket 22.

[0026] To facilitate the sliding of ice blocks, an ice guide plate 231 is provided at the bottom of the ice-making tank 23. The ice guide plate 231 is vertically arranged, and its upper edge slopes downward from the ice-making plate 61 toward the ice storage basket 22. This way, when a large ice block falls as a whole, its lower part will slide diagonally downward along the upper edge of the ice guide plate 231, ensuring that the large ice block slides precisely to the edge of the ice storage basket 22. At this time, an ice baffle plate 24 is also provided between the ice guide plate 231 and the ice storage basket 22. The ice baffle plate 24 is located diagonally below the upper edge of the ice guide plate 231, and is vertically arranged with an ice-blocking gap 25 between it and the ice guide plate 231. The bottom of the large ice block falls from the upper edge of the ice guide plate 231. After sliding out, the large ice block will reach the ice-blocking gap 25. At this point, the front side of the large ice block will contact the ice-blocking plate 24. Under the obstruction of the ice-blocking plate 24, the large ice block will flip downwards due to inertia, and then fall horizontally into the ice storage basket 22. After falling, the impact force will act on the entire surface of the ice block, so that the small ice blocks in each ice grid 611 will be impacted. Moreover, compared to the large ice block falling vertically, the upper part of the large ice block moves a longer distance (from the upper part of the ice-making plate 61 to the bottom of the ice storage basket 22), so the gravity acts on it for a longer time, and the impact force it receives is greater, resulting in better ice breaking effect. Therefore, it is easier for the large ice block to form more small ice blocks for easy retrieval. In order to enable the large ice block to fall horizontally, the horizontal width of the ice storage basket 22 is greater than the length formed by the same column of ice grids 611 in the vertical direction of the ice-making plate 61.

[0027] The beneficial effects of the embodiments of the present invention are as follows:

[0028] This invention relates to a household ice-making device comprising a housing 1, an inner liner assembly 2, a water circulation assembly 3, a refrigeration assembly 4, a spray assembly 5, and an ice-making assembly 6 mounted on the inner liner assembly 2. The ice-making assembly 6 includes an ice-making plate 61 vertically placed on an ice-making tank 23. Multiple ice trays 611 are provided on the side of the ice-making plate 61 closest to the ice storage basket 22. During ice making, each ice tray 611 forms a small ice cube, and multiple small ice cubes combine to form a large ice cube. To increase the impact force when the large ice cube falls, an ice guide plate 231 is provided at the bottom of the ice-making tank 23. The upper part of the ice guide plate 231... The edge is inclined downward from the ice-making plate 61 toward the ice storage basket 22. When melting ice, it is used to guide the ice block to slide downward at an angle. An ice baffle 24 is provided at the angle downward. The ice baffle 24 is vertically set and there is an ice-blocking gap 25 between it and the ice guide plate 231. When the large ice block slides down, its lower part will be stuck in the ice-blocking gap 25, so that the ice baffle 24 becomes the positioning point of the bottom of the ice block. At this time, the large ice block will generate a downward flipping motion under the inertia of sliding, which can increase the impact force on the large ice block when it falls, improve the ice-breaking effect of the large ice block falling into the ice storage basket 22, and make it easier for users to directly take out small ice blocks.

[0029] Specifically, see Figure 2 and Figure 3 The bottom of the ice-making tank 23 is provided with a support platform 26, and the ice-making plate 61 is placed on the support platform 26. There are multiple ice guide plates 231, which are evenly distributed on the side of the support platform 26 near the ice storage basket 22. In use, the water flowing down from the top of the ice-making plate 61 will pass through the support platform 26 and flow between two adjacent ice guide plates 231 to the bottom of the inner tank 21. The ice guide plates 231 can not only guide large ice blocks to slide down, but also guide water to flow down to the bottom of the inner tank 21. An ice-blocking platform 27 is provided between the ice storage basket 22 and the ice-making plate 61. The bottom of the ice guide plate 231 is fixed on the ice-blocking platform 27. Water will flow from the support platform 26 into the ice-blocking platform 27. The ice-blocking plate 24 is located on the edge of the ice-blocking platform 27 and protrudes upward. The ice guide plate 231 protrudes towards the ice-blocking plate 24, thereby guiding water to the ice-blocking platform 27. An ice-blocking gap 25 is formed between the outer edge of the ice guide plate 231 and the side of the ice-blocking plate 24. When a large ice block slides down, it will temporarily fall into the ice-blocking gap 25 and then flip and fall out of the ice-blocking gap 25.

[0030] See Figure 3The gap between the bottom of the inner tank 21 and the bottom of the ice storage basket 22 is a water storage space 211. Water flows down from the ice-blocking platform 27 and eventually collects in the water storage space 211. The ice guide plate 231 protrudes towards the ice-blocking plate 24, and a water guide groove 232 is formed between two adjacent ice guide plates 231. Water flows from the water guide groove 232 into the ice-blocking platform 27. The outer edge of the support platform 26 is provided with a water guide ramp 261. The water guide ramp 261 slopes downward and communicates with the water guide groove 232 to facilitate the flow of water into the water guide groove 232. Since the ice baffle 24 blocks the direction of water flow, in order to allow water to fall into the water storage space 211, the ice baffle platform 27 is provided with a water outlet 271 in the middle. The water outlet 271 is arranged vertically and is connected to the water storage space 211. After the water flows into the ice baffle platform 27 from the water guide channel 232, it will eventually fall into the water storage space 211 through the water outlet 271.

[0031] To achieve water circulation, the water circulation assembly 3 also includes a pump 32, which is located at the bottom of the receiving cavity 11 or the ice-making cavity 12. The water inlet of the pump 32 is connected to the water storage space 211, and the water outlet of the pump 32 is connected to the spray pipe 51. The pump 32 can pump water from the water storage space 211 to the spray pipe 51. The spray pipe 51 is located above the ice-making plate 61 and spans across both sides of the ice-making plate 61. The nozzle of the spray pipe 51 faces downward or diagonally downward. Under the pressure of the pump 32, water can be sprayed downward from the nozzle of the spray pipe 51, allowing water to flow down from the top of the ice-making plate 61.

[0032] The ice storage basket 22 is provided with a handle hole 221 on the upper part. The handle hole 221 is located on both sides of the ice storage basket 22, and the ice storage basket 22 can be lifted and used by using the handle hole 221. The side wall and bottom of the ice storage basket 22 are provided with multiple baffle holes 222. The baffle holes 222 are connected to the water storage space 211. When a large ice block falls into the ice storage basket 22, it breaks into small ice blocks. The baffle holes 222 can block the small ice blocks from falling into the water storage space 211, and the water formed by the melting of the small ice blocks will enter the water storage space 211 through the baffle holes 222.

[0033] The bottom of the inner tank 21 is provided with a water inlet groove 212. The water inlet groove 212 is recessed downward and communicates with the water inlet end of the pump 32. The recessed water inlet groove 212 ensures that the lowest water level can enter the pump 32. The edge of the water inlet groove 212 is inclined towards the center of the water inlet groove 212 to form a low-lying space to facilitate the flow of water into the water inlet groove 212. The water tank 31 is located above the refrigeration component 4. The bottom of the water tank 31 is connected to the water storage space 211 through a water replenishment valve 33. The water replenishment valve 33 is fixed to the bottom of the inner tank 21. The water tank 31 can provide a water source for the water system and can communicate with an external water source. Through the action of the water replenishment valve 33, the water storage space 211 can be replenished with water in a timely manner to prevent the pump 32 from running dry.

[0034] See Figure 4 The refrigeration assembly 4 includes a compressor 41, a condenser heat exchanger 42, an evaporator heat exchanger tube 43, and a throttling device 44. The exhaust end of the compressor 41 is located near the condenser heat exchanger 42 and communicates with it. The condenser heat exchanger 42 is connected to the evaporator heat exchanger tube 43 through the throttling device 44. The surface of the evaporator heat exchanger tube 43 abuts against the side of the ice-making plate 61 opposite to the ice tray 611. The evaporator heat exchanger tube 43 is connected to the return end of the compressor 41. In a normal refrigeration cycle, the refrigerant is ejected from the compressor 41. The high-temperature, high-pressure refrigerant enters the condenser heat exchanger 42 and condenses into a high-pressure liquid. It then passes through the throttling device 44 for cooling and pressure reduction, becoming a medium-temperature, medium-pressure gas-liquid mixture. It then enters the evaporator heat exchanger tube 43 for evaporation and heat absorption. After absorbing heat, it returns to the compressor 41 to continue the next cycle. When the refrigerant absorbs heat, the evaporation heat exchange tube 43 absorbs heat through the ice-making plate 61. At this time, water flows down from the ice-making plate 61 and gradually freezes when it encounters the cooled ice-making plate 61. Ice crystals are generated in each ice grid 611 and form a large ice block with multiple small ice blocks connected together.

[0035] To facilitate the removal of large ice blocks, the refrigeration assembly 4 also includes a one-way valve 45, which is located above the condenser heat exchanger 42. The exhaust end of the compressor 41 is connected to the inlet of the one-way valve 45, and the outlet of the one-way valve 45 is connected to the evaporator heat exchange tube 43. When ice removal is required, the one-way valve 45 is opened, and the high-temperature, high-pressure gas discharged from the compressor 41 directly enters the evaporator heat exchange tube 43 through the one-way valve 45. At this time, the evaporator heat exchange tube 43 generates high temperature, melting the small ice blocks adhering to the ice tray 611, thereby allowing the entire large ice block to detach from the ice-making plate 61 and fall off. The refrigeration component 4 also includes a cooling fan 46, which is located on the side of the condenser heat exchanger 42 away from the compressor 41. The cooling fan 46 is used to dissipate the heat generated by the condenser heat exchanger 42. The airflow of the cooling fan 46 is from the outside of the ice-making chamber 12 to the inside of the ice-making chamber 12. Compared with blowing from the inside of the ice-making chamber 12 to the outside, this direction of airflow has less wind resistance, a larger airflow, and can also dissipate heat and cool the compressor 41.

[0036] See Figure 1 The ice-making chamber 12 is provided with a fixed cover plate 13 above it. The fixed cover plate 13 is provided with a mounting hole 131. The box body 1 also includes an upper cover plate 14. The upper cover plate 14 is provided with a downwardly recessed opening groove 141. The upper cover plate 14 can be detachably inserted into the mounting hole 131. Using the opening groove 141, the upper cover plate 14 can be removed from the mounting hole 131, which facilitates operations such as adding water to the water tank 31. The receiving cavity 11 is provided with a flip cover plate 15 above it. One side of the flip cover plate 15 is hinged to one side of the fixed cover plate 13. The flip cover plate 15 can be flipped open relative to the fixed cover plate 13, which facilitates taking ice from the ice storage basket 22 or taking out the ice storage basket 22.

[0037] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
