Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and more specifically, to an ice-making device, a water purifier, and an ice maker. Background Technology

[0002] Water purifiers are common cooling devices in daily life. By purifying water, they enable people to obtain pure drinking water. In the cooling mode, advanced water purifiers can not only purify water but also make ice and store the ice in an ice chamber. Since the ice chamber itself does not have a cooling function, it will gradually absorb heat from the environment over time, causing the ice to melt. Therefore, existing technologies face the problem of how to ensure that the ice chamber can preserve the ice well and prevent it from melting. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a refrigeration device with better energy utilization.

[0004] To achieve the above objectives, the technical solution provided by an embodiment of this utility model is as follows:

[0005] An ice-making device includes: an ice storage body for storing ice blocks; a refrigeration component including an evaporator, an inlet pipe, a return pipe, and a pump body, wherein the pump body is connected to the inlet end of the evaporator via the inlet pipe, and the return pipe is connected to the outlet end of the evaporator, the refrigeration component being located above the ice storage body and used to prepare ice blocks; and a cooling conduction component disposed on the outer periphery of the ice storage body, at least a portion of which is fixedly connected to the outer surface of the return pipe, the surface of which is in contact with the outer surface of the ice storage body, and used to conduct cold energy in the return pipe to the ice storage body.

[0006] In this application, the gas in the intake pipe of the refrigeration component is depressurized by the expansion valve, resulting in a lower temperature. The cooled gas then passes through the evaporator to produce ice. The produced ice falls into the ice chamber below and is stored. After the gas passes through the evaporator to make ice, its temperature rises above the intake temperature and enters the return pipe for the next cycle. However, at this point, the temperature of the return pipe is still lower than the ambient temperature, meaning some cooling capacity remains unutilized. This application addresses this by installing a cooling conductive component on the outer periphery of the ice chamber and fixing a portion of the component to the return pipe. This allows the cooling conductive component to connect to both the return pipe of the refrigeration component and the ice chamber itself. After the cooling capacity of the refrigeration component is used for ice making, the residual cooling in the return pipe can be conducted to the outer surface of the ice chamber through heat conduction. This effectively lowers the temperature around the outer periphery of the ice chamber, reduces the temperature difference between the inside and outside of the ice chamber, and slows down the rate of temperature rise inside the ice chamber, thus extending the ice storage time. Meanwhile, by connecting the return pipe of the refrigeration component to the cooling conduction component, there is no need to add an additional refrigeration component. The residual cold of the return pipe is used efficiently without increasing costs, resulting in higher energy utilization efficiency and longer storage time of ice in the ice cellar.

[0007] Furthermore, the cooling component includes a vapor chamber plate, one end of which is connected to the return air pipe, and one side surface of the vapor chamber plate is attached to the surface of the ice chamber body. Connecting the return air pipe and the ice chamber body through the vapor chamber plate increases the efficiency of cold energy transfer and the contact area with the ice chamber body.

[0008] Furthermore, the vapor chamber has a refrigerant cavity for containing the refrigerant. Rapid transfer of cooling capacity is achieved through heat transfer via convection within the refrigerant cavity.

[0009] Furthermore, one end of the heat spreader has a curved section that fits against the outer circumferential surface of the return pipe. By setting the curved section to contact the return pipe, the contact area between the heat spreader and the return pipe can be increased. Since the curved section of the heat spreader at least partially fits against the outer circumferential surface of the return pipe, the connection effect between the heat spreader and the return pipe can be improved.

[0010] Furthermore, the cooling component also includes a temperature-conducting plate, at least a portion of which is in contact with the heat spreader, and one side surface of the temperature-conducting plate is attached to the surface of the ice chamber body. The two sides of the temperature-conducting plate connect the ice chamber body and the heat spreader, respectively. As a bridge, the temperature-conducting plate can further improve the cooling effect.

[0011] Furthermore, the heat-conducting plate is a solid metal plate. Heat-conducting plates made from solid metal plates are easy to manufacture and process, and have a simple structure and low cost.

[0012] Furthermore, the temperature guide plate is positioned at the end of the vapor chamber away from the return pipe. By connecting the temperature guide plate and the return pipe to both ends of the vapor chamber, a cold air flow path is formed, enabling the flow of cold air. The temperature guide plate and the vapor chamber can be connected by screws, welding, or bonding.

[0013] Furthermore, the temperature distribution plate and the temperature guide plate are located on the same side of the ice chamber body. This arrangement reduces the connection length between the temperature distribution plate and the temperature guide plate, facilitating connection and maintenance.

[0014] Furthermore, the ice-making device also includes a heat-conducting medium layer, through which the cold-conducting components contact the ice chamber body for heat conduction. By setting up the heat-conducting medium layer, the transfer of cold energy can be accelerated, and the exchange of cold energy between the ice chamber body and the temperature-conducting plate can be achieved more quickly.

[0015] Furthermore, the return air pipe is arranged circumferentially along the body of the ice chamber and is attached to the surface of the ice chamber body. By attaching the return air pipe to the surface of the ice chamber body and arranging it circumferentially, the cooling capacity within the return air pipe can be further utilized.

[0016] This utility model also provides a water purifier, including a shell, a water storage unit, a water purification unit, and the aforementioned ice-making device. The water storage unit, the water purification unit, and the ice-making device are all disposed inside the shell, and the water filtered by the water purification unit is stored in the water storage unit.

[0017] This utility model also provides an ice maker, including a housing, an electrical control component, and the aforementioned ice-making device, wherein the ice-making device and the electrical control component are disposed within the housing.

[0018] This utility model has the following beneficial effects:

[0019] In this application, the gas in the intake pipe of the refrigeration component is depressurized by the expansion valve, resulting in a lower temperature. The cooled gas then passes through the evaporator to produce ice. The produced ice falls into the ice chamber below and is stored. After the gas passes through the evaporator to make ice, its temperature rises above the intake temperature and enters the return pipe for the next cycle. However, at this point, the temperature of the return pipe is still lower than the ambient temperature, meaning some cooling capacity remains unutilized. This application addresses this by installing a cooling conductive component on the outer periphery of the ice chamber and fixing a portion of the component to the return pipe. This allows the cooling conductive component to connect to both the return pipe of the refrigeration component and the ice chamber itself. After the cooling capacity of the refrigeration component is used for ice making, the residual cooling in the return pipe can be conducted to the outer surface of the ice chamber through heat conduction. This effectively lowers the temperature around the outer periphery of the ice chamber, reduces the temperature difference between the inside and outside of the ice chamber, and slows down the rate of temperature rise inside the ice chamber, thus extending the ice storage time. Meanwhile, by connecting the return pipe of the refrigeration component to the cooling component, there is no need to add an additional refrigeration component. The residual cold of the return pipe is used efficiently without increasing the cost, resulting in higher energy utilization efficiency and longer storage time of ice in the ice cellar. This solves the problem of how existing technologies can ensure that the ice cellar can preserve ice well and prevent it from melting easily. Attached Figure Description

[0033] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0034] To address the problem in existing technologies of how to ensure that ice can be well preserved in ice storage and that the ice does not melt easily, this utility model provides an ice-making device, a water purifier, and an ice maker.

[0035] like Figures 1 to 3 As shown, ice-making devices are commonly used in water purifiers or ice makers to achieve simultaneous water purification and ice making, or to perform ice making operations independently. A water purifier, in addition to the ice-making device, includes a housing, a water storage unit, and a water purification unit. These components, along with the ice-making device, are all housed within the housing. Water filtered by the purification unit is stored in the storage unit. During the water purification process, the ice-making device can produce ice, providing users with purified water and ice to meet diverse needs. An ice maker, besides the ice-making device, also includes a housing and electrical control components. Both the ice-making device and the electrical control components are housed within the housing, and ice making is controlled by the electrical control components.

[0036] The ice-making device will now be described in detail.

[0037] like Figures 1 to 3 As shown, the ice-making device includes an ice storage body 10, a refrigeration component 20, and a cold-conducting component 30. The ice storage body 10 is used to store ice cubes. The refrigeration component 20 includes an evaporator 23, an inlet pipe 22, a return pipe 21, and a pump body 24. The pump body 24 is connected to the inlet end of the evaporator 23 via the inlet pipe 22, and the return pipe 21 is connected to the outlet end of the evaporator 23. The refrigeration component 20 is located above the ice storage body 10 and is used to prepare ice cubes. The cold-conducting component 30 is disposed on the outer periphery of the ice storage body 10, and at least a portion of the cold-conducting component 30 is connected to the return pipe 21. The cold-conducting component 30 is used to conduct the cold energy in the return pipe 21 to the ice storage body 10.

[0038] In this application, the gas in the inlet pipe 22 of the refrigeration component 20 is depressurized by the expansion valve and its temperature drops. The gas with the lower temperature passes through the evaporator 23 to make ice. The prepared ice falls into the ice chamber body 10 below and is stored. After the gas passes through the evaporator 23 to make ice, its temperature rises above the inlet temperature and enters the return pipe 21 for the next cycle. However, at this time, the temperature of the return pipe 21 is still lower than the ambient temperature, and some of the cooling capacity is not utilized. This application provides a cooling-conducting component 30 on the outer periphery of the ice storage unit 10, and a portion of the cooling-conducting component 30 is fixedly connected to the return air pipe 21. This allows the cooling-conducting component 30 to be connected to both the return air pipe 21 of the refrigeration component 20 and the ice storage unit 10. After the cooling capacity of the refrigeration component is used for ice making, the residual cold from the return air pipe 21 can be conducted to the outer surface of the ice storage unit 10 via heat conduction. This effectively reduces the temperature around the outer periphery of the ice storage unit 10, decreases the temperature difference between the inside and outside of the ice storage unit 10, and slows the rate of temperature rise inside the ice storage unit 10, thus extending the ice storage time inside the ice storage unit 10. Furthermore, by connecting the return air pipe 21 of the refrigeration component 20 to the cooling-conducting component 30, there is no need to add an additional refrigeration component 20. This efficiently utilizes the residual cold from the return air pipe 21 without increasing costs, resulting in higher energy efficiency and a longer ice storage time in the ice storage unit 10.

[0039] Since existing water purifiers or other refrigeration equipment use evaporation and heat absorption as their operating principle during ice making, a large amount of cold energy is generated during the ice making process. This cold energy flows out along the return pipe 21 and cannot be utilized. The main purpose of this utility model is to find a way to utilize this portion of the cold energy.

[0040] In this embodiment, to better utilize the cooling capacity generated by the refrigeration component 20, the surface of the cooling guide component 30 is arranged in contact with the outer surface of the ice chamber body 10. Through the contact between the cooling guide component 30 and the outer surface of the ice chamber body 10, cooling capacity can be transferred from the return air pipe 21 through the cooling guide component 30 to the ice chamber body 10. Compared to the return air pipe 21 directly contacting the ice chamber body 10, the cooling guide component 30 increases the speed of cooling capacity transfer and improves the contact area between the cooling capacity and the ice chamber body 10.

[0041] Specifically, the return air pipe 21 is located on one side of the ice chamber body 10, and the two ends of the cooling guide component 30 are connected to the return air pipe 21 and the ice chamber body 10 respectively. When the cold energy passes through the return air pipe 21, it enters the ice chamber body 10 through the cooling guide component 30, realizing the secondary utilization of the cold energy. Compared with the traditional technology, this utility model can better utilize the cold energy, and this method can also ensure that the ice chamber body 10 is at a lower temperature, avoiding the phenomenon of ice melting due to the temperature drop of the ice chamber body 10 after ice making, thus improving the user experience.

[0042] It is understandable that, in addition to providing the cold-conducting component 30 to facilitate the transfer of cold energy between the return air pipe 21 and the ice chamber body 10, in order to further utilize the cold energy of the return air pipe 21, in an embodiment of this invention (not shown), the return air pipe 21 is partially arranged along the circumference of the ice chamber body 10 and adheres to the surface of the ice chamber body 10. By adhering the return air pipe 21 to the surface of the ice chamber body 10 and arranging it circumferentially, the cold energy within the return air pipe 21 can be further utilized.

[0043] Specifically, a portion of the return air pipe 21 is connected to the cooling conductor 30, and the other portion is wrapped around the ice chamber body 10 at intervals. Of course, the wrapped portion should not be too large, for example, only one turn, to avoid most of the cold energy on the return air pipe 21 being transferred to the ice chamber body 10 through the cooling conductor 30, resulting in insufficient cold energy on the return air pipe 21. That is, the temperature of the return air pipe 21 should be higher than the temperature of the ice chamber body 10, to prevent cold energy from transferring from the ice chamber body 10 to the return air pipe 21.

[0044] like Figures 1 to 3 As shown, the cooling conduit assembly 30 includes a heat spreader 31, one end of which is connected to the return air pipe 21, and one side surface of the heat spreader 31 is attached to the surface of the ice chamber body 10. Connecting the return air pipe 21 and the ice chamber body 10 through the heat spreader 31 can increase the efficiency of cold energy transfer and the contact area with the ice chamber body 10.

[0045] Specifically, the heat spreader 31 and the return air pipe 21 can be bonded or snapped together to improve the connection effect. The return air pipe 21 abuts against one side of the heat spreader 31, and the other side of the heat spreader 31 abuts against the surface of the ice chamber body 10; that is, the return air pipe 21 and the ice chamber body 10 are located on opposite sides of the heat spreader 31. Alternatively, the return air pipe 21 and the ice chamber body 10 can be located on the same side of the heat spreader 31.

[0046] In another embodiment of this invention (not shown), the temperature distribution plate 31 has a refrigerant cavity for containing refrigerant. Rapid transfer of cooling capacity is achieved through heat transfer via convection within the refrigerant cavity.

[0047] Specifically, refrigerant is placed inside the temperature distribution plate 31, and the transfer of cooling capacity is achieved by utilizing the property of refrigerant to flow or undergo phase change when heated. For example, a partition is set in the refrigerant cavity, which divides the refrigerant cavity into upper and lower chambers. The refrigerant connects to the refrigerant cavity through both ends of the partition, and after the cooling capacity arrives, it undergoes a phase change and moves towards the ice chamber body 10 to complete the transfer of cooling capacity. Propane or ammonia can be used as the refrigerant.

[0048] It is understandable that the larger the contact area between the heat spreader 31 and the return pipe 21, the better the connection effect, and the more stable the cold energy transfer will be. Therefore, the connection method can be considered.

[0049] like Figures 2 to 3 As shown, to improve the connection effect and contact area between the heat spreader 31 and the return pipe 21, one end of the heat spreader 31 has a bent section 311, which is attached to the outer peripheral surface of the return pipe 21. By setting the bent section 311 to contact the return pipe 21, the contact area between the heat spreader 31 and the return pipe 21 can be increased. Since the bent section 311 of the heat spreader 31 is at least partially attached to the outer peripheral surface of the return pipe 21, the connection effect between the heat spreader 31 and the return pipe 21 can be improved.

[0050] Specifically, the cross-section of the curved section 311 is approximately S-shaped, and the end of the curved section 311 can have an arc-shaped groove that is compatible with the return air pipe 21. The return air pipe 21 can be snapped into the arc-shaped groove. This method of connection is stable and simple, and is easy to assemble and maintain.

[0051] In another embodiment of this utility model (not shown), the temperature distribution plate 31 is a straight plate section, and the return air pipe 21 is bonded to the temperature distribution plate 31 or connected by a limiting clamp.

[0052] In order to further increase the cooling capacity that the icebox body 10 can obtain, such as Figures 1 to 3 As shown, the cooling component 30 also includes a temperature-conducting plate 32, at least a portion of which is in contact with the temperature-equalizing plate 31, and one side surface of the temperature-conducting plate 32 is attached to the surface of the ice chamber body 10. The two sides of the temperature-conducting plate 32 are respectively connected to the ice chamber body 10 and the temperature-equalizing plate 31. The temperature-conducting plate 32 acts as a bridge, which can further improve the cooling effect.

[0053] Specifically, the two ends of the temperature distribution plate 31 are connected to the temperature conduction plate 32 and the return air pipe 21, respectively. The middle part of the temperature distribution plate 31 is in contact with the ice chamber body 10. Through the cooperation between the temperature distribution plate 31 and the temperature conduction plate 32, the ice chamber body 10 can obtain more cooling capacity, which ultimately enables the ice chamber body 10 to achieve a good "heat preservation effect", preventing the temperature of the ice chamber body 10 from dropping, and thus preventing the ice from melting.

[0054] In this embodiment, the temperature-conducting plate 32 has a first plate segment 321 and a second plate segment 322, which are connected sequentially. The first plate segment 321 and the second plate segment 322 have a bending angle. After the temperature-conducting plate 32 is installed, one side of the temperature-equalizing plate 31 adheres to the ice chamber body 10, and the other side is connected to the side of the first plate segment 321 facing the ice chamber body 10. That is, the first plate segment 321 adheres to the temperature-equalizing plate 31, and the second plate segment 322 adheres to the ice chamber body 10.

[0055] In this embodiment, the end of the heat spreader 31 near the heat conductor 32 is an approximately rectangular plate, the end of the heat conductor 32 near the heat spreader 31 has the same length and width as the heat spreader 31, and the end of the heat conductor 32 away from the heat spreader 31 has a greater length and width than the heat spreader 31. This arrangement allows for a larger cold energy transfer area between the heat conductor 32 and the ice chamber body 10.

[0056] In this embodiment, the temperature guide plate 32 is disposed at the end of the heat spreader 31 away from the return pipe 21. By connecting the temperature guide plate 32 and the return pipe 21 to both ends of the heat spreader 31, a cold flow path is formed to realize the flow of cold energy. The temperature guide plate 32 and the heat spreader 31 can be connected by screws, welding or bonding.

[0057] In this embodiment, the temperature distribution plate 31 and the temperature guiding plate 32 are located on the same side of the ice chamber body 10. By arranging the temperature distribution plate 31 and the temperature guiding plate 32 on the same side of the ice chamber body 10, the connection length between the temperature distribution plate 31 and the temperature guiding plate 32 can be reduced, which facilitates connection and maintenance.

[0058] Specifically, the first section 321 of the heat spreader 31 and the heat conductor 32 are at the same height.

[0059] Since this utility model includes a temperature-conducting plate 32 to further utilize the cooling capacity in the return gas pipe 21, it has multiple embodiments, and the material and structure of the temperature-conducting plate 32 will be described.

[0060] In this embodiment, the temperature-conducting plate 32 is a solid metal plate. The temperature-conducting plate 32 made of a solid metal plate is easy to manufacture and has a simple structure and low cost.

[0061] Specifically, solid metal plates are less expensive, have a certain degree of ductility for easy processing, and possess good thermal conductivity, facilitating rapid transfer of cold energy. The plate-like metal material also ensures uniform cold energy transfer to the ice chamber body 10, resulting in more uniform ice quality and better overall ice distribution within the ice chamber body 10.

[0062] Meanwhile, for users, in addition to conducting heat, the heat conduction plate 32 also needs to have a long enough service life. Frequent replacement reduces the user experience. Solid metal plates have a longer service life and can reduce replacement and maintenance costs.

[0063] To improve the conduction of cold energy, the ice-making device also includes a heat-conducting medium layer, through which the cold-conducting component 30 contacts the ice chamber body 10 for heat conduction.

[0064] Specifically, a heat-conducting medium layer is disposed between the temperature-equalizing plate 31 and the ice chamber body 10, and between the second plate segment 322 and the ice chamber body 10. This heat-conducting medium layer improves the heat transfer efficiency between the cooling component 30 and the ice chamber body 10, ensuring that cold energy can be quickly and evenly transferred to the interior of the ice chamber body 10. This results in a more stable internal temperature for the ice chamber body 10 and a longer storage time for the ice.

[0065] In this embodiment, the thermally conductive medium layer is one of the following: thermally conductive grease, thermally conductive pad, thermally conductive adhesive, metal foil, and phase change material.

[0066] In this embodiment, to ensure thermal conductivity and connection, the thermally conductive medium layer is a thermally conductive adhesive.

[0067] like Figures 1 to 2 As shown, the ice-making device also includes an isolator 40 and a capillary tube 50. One end of the isolator 40 is connected to the refrigerant storage tank, and the other end is connected to the air inlet pipe 22 through the capillary tube 50. The isolator 40 is equipped with a desiccant to dry the refrigerant. This utility model has the following beneficial effects: by setting the refrigeration component 20 to refrigerate the ice chamber body 10, the temperature of the ice chamber body 10 is reduced, causing the water temperature in the ice chamber body 10 to decrease and transform into "ice water", or directly form ice, thereby meeting the user's refrigeration or ice-making needs. The cold conduction component 30 connects the return air pipe 21 of the refrigeration component 20 and the ice chamber body 10, completing the secondary cooling of the ice chamber body 10 by the cold energy on the return air pipe 21, thereby ensuring that the ice chamber body 10 is always at a low temperature, and making use of the cold energy generated by the refrigeration of the refrigeration component 20 again, avoiding the loss of this part of the cold energy directly through the return air pipe 21.

[0068] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0069] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
