Description

Technical Field

[0001] This application relates to the field of water dispenser technology, and more particularly to an ice-making water dispenser. Background Technology

[0002] Water dispensers, as an economical household appliance, are widely popular; ice makers, also an economical appliance, have gradually entered homes after being primarily owned by hotels, restaurants, entertainment venues, and canteens. In recent years, considering factors such as saving consumers money, facilitating daily use and maintenance, and competing in the market, household appliance manufacturers have launched ice-making water dispensers, combining the functions of a water dispenser and an ice maker into one unit.

[0003] Generally speaking, since ice-making water dispensers integrate at least the functions of drinking water and making ice, their structure will include at least a water storage tank, a refrigerator body, an ice-making component, and some piping components. The ice-making component includes structures such as a compressor, evaporator, and condenser, which can complete the transformation process of liquid water in the refrigerator body into solid ice.

[0004] In related technologies, ice-making water dispensers generally dissipate heat by opening ventilation holes on the surface of the casing. This heat dissipation method requires the ice-making water dispenser to be placed in a relatively open environment to prevent the external environment from blocking the ventilation holes and affecting its heat dissipation effect. Therefore, the existing heat dissipation method of ice-making water dispensers cannot well meet the heat dissipation requirements of the usage scenario where the ice-making water dispenser is placed against the wall. Utility Model Content

[0005] In view of this, this application provides an ice-making water dispenser to solve the technical problem that the heat dissipation method of existing ice-making water dispensers cannot adequately meet the heat dissipation requirements of ice-making water dispensers placed against a wall.

The cold water tank is also connected to the buffer water tank through the second part of the main pipeline assembly. The cold water tank is also circulated through the ice-making body through the third part of the main pipeline assembly. At least one of the second part of the pipeline and the third part of the pipeline is partially disposed on the side wall of the chassis housing with heat dissipation holes.

[0007] Optionally, in some embodiments of this application, the ice-making water dispenser further includes a heating pipe assembly, which is disposed in the casing. The heating pipeline assembly includes a first pipeline, a heater, and a second pipeline. The water inlet of the heater is connected to the water outlet of the buffer water tank and the first water outlet of the cold water tank through the first pipeline. The water outlet of the heater is connected to a second water outlet provided on the surface of the casing through the second pipeline. In the first pipeline, the branch connecting the first water outlet of the cold water tank and the water inlet of the heater is at least partially provided on the side wall of the casing with heat dissipation holes.

[0008] Optionally, in some embodiments of this application, the first pipeline includes a first branch, a second branch, a third branch, and a first switching valve. One end of the third branch is connected to the water inlet of the heater, and the other end of the third branch is connected to the first branch and the second branch respectively through the first switching valve. The first branch is connected to the water outlet of the buffer water tank, and the second branch is connected to the first water outlet of the cold water tank. The second branch is disposed on the side wall of the chassis housing with heat dissipation holes, and / or the third branch is disposed on the side wall of the chassis housing with heat dissipation holes.

[0009] Optionally, in some embodiments of this application, at least some of the pipes disposed on the side wall of the chassis housing with heat dissipation holes are arranged in a curved and extended layout.

[0010] Optionally, in some embodiments of this application, the location of the heat dissipation hole is adjacent to the pipe disposed on the same side wall.

[0011] Optionally, in some embodiments of this application, the ice-making assembly includes the evaporator, compressor, de-icing valve, and condenser module; The refrigerant outlet of the evaporator is sequentially connected to the compressor, the de-icing valve, the condenser module, and the first refrigerant inlet of the evaporator to form an ice-making refrigerant circulation path; The de-icing valve is also connected to the second refrigerant inlet of the evaporator to form a de-icing refrigerant passage.

[0012] Optionally, in some embodiments of this application, the condenser module includes a condenser and a cooling fan, wherein the cooling fan is disposed between the condenser and a side wall of the chassis housing having heat dissipation holes.

[0013] Optionally, in some embodiments of this application, a heat-conducting structure is provided between the compressor and the side wall of the chassis housing with heat dissipation holes.

[0014] Optionally, in some embodiments of this application, the first portion of the pipeline includes a third pipeline having a second pump body, and the second water outlet of the cold water tank is connected to the first water outlet through the third pipeline; and / or, The second part of the pipeline includes a fourth pipeline with a third pump body, wherein the water inlet of the cold water tank is connected to the water outlet of the buffer tank through the fourth pipeline; and / or, The third part of the pipeline includes a fifth pipeline and a sixth pipeline with a fourth pump body.

[0016] The ice-making water dispenser provided in this application embodiment, through the above-described structural arrangement, has at least one of the second part of the pipeline and the third part of the pipeline in its main pipeline assembly partially disposed on the side wall of the casing housing with heat dissipation holes. Therefore, the water flowing in its main pipeline assembly can at least partially flow through the side wall of the casing housing with heat dissipation holes to carry away the heat near the heat dissipation holes. This means that these heat dissipation holes can dissipate heat not only by air but also by water flow, thereby greatly improving the heat dissipation capacity of these heat dissipation holes. This ensures that the ice-making water dispenser has good heat dissipation performance and can well meet the heat dissipation requirements of the ice-making water dispenser when placed against a wall.

[0024] To better understand and implement this application, the technical solutions in this application will be clearly and completely described below with reference to the accompanying drawings.

[0025] In the description of this application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0027] In one embodiment, see Figures 1 to 4 This application provides an ice-making water dispenser 1, which mainly includes a casing 10 and a buffer water tank 20, a refrigerator body 30, a cold water tank 40, an ice-making component 50, and a main pipeline assembly 60, all disposed within the casing 10. The evaporator 51 of the ice-making component 50 is located within the refrigerator body 30, which is connected to an ice outlet 11 on the surface of the casing 10. The cold water tank 40 is connected to a first water outlet 12 on the surface of the casing 10 via a first portion of the main pipeline assembly 60. The cold water tank 40 is also connected to the buffer water tank 20 via a second portion of the main pipeline assembly 60, and is also circulatedly connected to the refrigerator body 30 via a third portion of the main pipeline assembly 60. At least one of the second and third portions of the pipeline is partially disposed on the side wall of the casing 10 with heat dissipation holes 13.

[0028] It should be noted that the ice-making water dispenser 1 in this application embodiment mainly refers to a device that has both the functions of a conventional water dispenser and a conventional ice maker. That is, when the first water outlet 12 is opened, it can provide room temperature water or cold water for users to drink, and when the ice outlet 11 is opened, it can provide ice cubes for users to use. Generally speaking, the buffer water tank 20 mentioned above, as the water supply source for the entire ice-making water dispenser 1, is connected to the cold water tank 40 through the second part of the main pipeline assembly 60. The water in the cold water tank 40 can be led to the first water outlet 12 through the first part of the main pipeline assembly 60 to provide drinking water for users, and can also be led to the ice-making body 30 through the third part of the main pipeline assembly 60, where it is converted into solid ice by the evaporator 51 of the ice-making assembly 50 to provide ice cubes for users to use.

[0029] In this way, the ice-making water dispenser 1 of this application embodiment, through the above-described structural arrangement, since at least one of the second part of the pipeline and the third part of the pipeline in its main pipeline assembly 60 is partially disposed on the side wall of the casing 10 with heat dissipation holes 13, the water flowing in its main pipeline assembly 60 can at least partially flow through the side wall of the casing 10 with heat dissipation holes 13 to carry away the heat near the heat dissipation holes 13. This means that these heat dissipation holes 13 can dissipate heat not only by air but also by water flow, thereby greatly improving the heat dissipation capacity of these heat dissipation holes 13. This ensures that the ice-making water dispenser 1 has good heat dissipation performance and can well meet the heat dissipation requirements of the ice-making water dispenser 1 when placed against a wall.

[0030] In some examples, such as Figure 3 , Figure 4 and Figure 5 As shown, the ice-making water dispenser 1 also includes a heating pipe assembly 70, which is disposed within the casing 10. The heating pipe assembly 70 includes a first pipe 71, a heater 72, and a second pipe 73. The water inlet of the heater 72 is connected via the first pipe 71 to the water outlet of the buffer water tank 20 and the first water outlet of the cold water tank 40, respectively. The water outlet of the heater 72 is connected via the second pipe 73 to a second water outlet 14 disposed on the surface of the casing 10. In the first pipe 71, a branch connecting the first water outlet of the cold water tank 40 and the water inlet of the heater 72 is at least partially disposed on the side wall of the casing 10 with the heat dissipation holes 13. Thus, with the above structural arrangement, by adding the heating pipe assembly 70, the ice-making water dispenser 1 also has a hot water preparation function, providing hot water for the user when the second water outlet 14 is opened. Alternatively, by also installing some of the pipes in the added heating pipe assembly 70 on the side wall of the casing 10 with the heat dissipation holes 13, the cooler water in the cold water tank 40, as it flows towards the water inlet of the heater 72, also flows through the side wall of the casing 10 with the heat dissipation holes 13, thus carrying away heat from the vicinity of the heat dissipation holes 13 and further enhancing their heat dissipation capacity. Furthermore, since the water flow carries away heat from the vicinity of the heat dissipation holes 13 while simultaneously absorbing this heat, causing the water temperature to rise, the heater 72 can then heat this warmer water to the preset temperature with less power and in a shorter time.

[0031] In some examples, such as Figure 4 and Figure 5As shown, the first pipeline 71 includes a first branch 711, a second branch 712, a third branch 713, and a first switching valve 714. One end of the third branch 713 is connected to the water inlet of the heater 72, and the other end of the third branch 713 is connected to the first branch 711 and the second branch 712 respectively through the first switching valve 714. The first branch 711 is connected to the water outlet of the buffer water tank 20, and the second branch 712 is connected to the first water outlet of the cold water tank 40. The second branch 712 is located on the side wall of the casing 10 with the heat dissipation holes 13, and / or the third branch 713 is located on the side wall of the casing 10 with the heat dissipation holes 13. Thus, with the above structural arrangement, the water inlet of the heater 72 can be switched between the water outlet of the buffer water tank 20 and the first water outlet of the cold water tank 40 through the first switching valve 714. At the same time, the branch connecting the first water outlet of the cold water tank 40 and the water inlet of the heater 72 in the first pipe 71 can be well arranged, at least partially, on the side wall of the casing 10 with the heat dissipation hole 13, through the second branch 712 and / or the structural arrangement.

[0032] It should be noted that the heating pipe assembly 70 in the above example also includes a first pump body 715, a first temperature sensor 716, and a second temperature sensor 731. Specifically, the first pump body 715 can be disposed in the third branch 713 to increase the water flow rate in the third branch 713 when needed, allowing the water to flow into the heater 72 more quickly. Additionally, the first temperature sensor 716 can also be disposed in the third branch 713 to detect the water temperature in the first pipe 71 in real time, i.e., the temperature of the water before entering the heater 72. The second temperature sensor 731 can be disposed in the second pipe 73 to detect the water temperature in the second pipe 73 in real time, i.e., the temperature of the water after exiting the heater 72. The heater 72 in this example can specifically be a heating structure used in conventional water dispensers.

[0033] In some examples, such as Figure 5 As shown, at least some of the pipes installed on the side wall of the chassis housing 10 with the heat dissipation holes 13 are arranged in a curved and extended layout. In this way, the contact area between these pipes and the corresponding side wall can be effectively extended through the above-described structural arrangement, thereby further improving their heat dissipation capacity.

[0034] In some examples, such as Figure 5 As shown, the heat dissipation holes 13 are positioned adjacent to the pipes located on the same side wall. This structural arrangement allows the heat from the heat dissipation holes 13 to have greater contact with the corresponding pipes during the heat dissipation process, thereby further enhancing the heat dissipation capacity of these holes 13.

[0035] In some examples, such as Figure 1 and Figure 2 As shown, the casing 10 has a cuboid structure, including a first side wall, a second side wall, a third side wall, and a fourth side wall connected end to end. The first side wall has an ice outlet 11, a first water outlet 12, and a second water outlet 14. The buffer water tank 20 is located adjacent to the second side wall. The lower half of the second side wall and the third side wall both have ventilation holes 13 for heat dissipation. The aforementioned pipes on the side walls can be located inside the second side wall and / or the third side wall. Generally, when the ice-making water dispenser 1 is placed against a wall, the third side wall is usually against the wall. Therefore, several abutment blocks 15 protrude from the outer side of the third side wall to ensure that the third side wall is not completely against the wall when the ice-making water dispenser 1 is placed against the wall, thus ensuring the heat dissipation capacity of the ventilation holes 13 on the third side wall.

[0036] In some examples, such as Figure 3 and Figure 5 As shown, the ice-making assembly 50 includes an evaporator 51, a compressor 52, a defrost valve 53, and a condenser module 54. The refrigerant outlet of the evaporator 51 is sequentially connected to the compressor 52, the defrost valve 53, the condenser module 54, and the first refrigerant inlet of the evaporator 51 to form an ice-making refrigerant circulation path. The defrost valve 53 is also connected to the second refrigerant inlet of the evaporator 51 to form a defrost refrigerant path. Thus, with the above structural configuration, when ice making is required, the compressor 52, the de-icing valve 53, the condenser module 54, and the evaporator 51 are combined to form an ice-making refrigerant passage. Heat is absorbed and cooled at the evaporator 51, causing the water temperature in the refrigerator body 30 to drop below the freezing point, thereby completing the corresponding ice-making operation. After ice making is completed, the surface temperature of the evaporator 51 is extremely low (approximately -10°C to -20°C), and the ice will adhere tightly to the mold. At this time, the de-icing valve 53 can be used to switch to the de-icing refrigerant passage, allowing the refrigerant with a higher temperature to flow briefly to the evaporator 51 to heat the surface of the evaporator 51, causing the edges of the ice to melt slightly, thereby loosening the ice and causing it to fall into the ice-making box 31. The ice-making box 31 is then flipped over and poured into the ice storage box 32.

[0037] It should be noted that the refrigerator body 30 in this example includes an ice-making box 31 and an ice storage box 32. The ice-making box 31 is placed in the ice storage box 32 and is located in the upper half of the ice storage box 32. During ice making, heat is absorbed and cooled at the evaporator 51, which can cause most of the liquid water in the ice-making box 31 to be converted into solid ice. After ice making is completed, the ice-making box 31 can be flipped over so that the unsolidified liquid water can be poured into the ice storage box 32 and then flow back into the cold water tank 40. Then, after the ice cubes loosen and fall into the ice-making box 31, the ice-making box 31 can be flipped over again so that the ice cubes can be poured into the ice storage box 32. After being stirred by the stirring and ice-dispensing device 33 in the ice storage box 32, and when necessary, the ice cubes are conveyed to the ice outlet 11 to complete the corresponding ice dispensing operation.

[0038] In some examples, such as Figure 3 As shown, the condenser module 54 includes a condenser 541 and a cooling fan 542. The cooling fan 542 is disposed between the condenser 541 and the side wall of the chassis 10 with the heat dissipation holes 13 (preferably the second side wall mentioned above). Thus, through this structural arrangement, the heat generated by the condenser 541 during operation can be quickly blown by the cooling fan 542 to the side wall of the chassis 10 with the heat dissipation holes 13, thereby achieving the corresponding heat dissipation treatment.

[0039] In some examples, such as Figure 3 As shown, a heat-conducting structure is provided between the compressor 52 and the side wall of the casing 10 with the heat dissipation holes 13 (specifically, preferably the third side wall mentioned above). Thus, through this structural arrangement, the heat generated by the compressor 52 during operation can be quickly directed to the side wall of the casing 10 with the heat dissipation holes 13 via the heat-conducting structure, thereby achieving the corresponding heat dissipation treatment.

[0040] It should be noted that the heat-conducting structure in this example can be a metal heat-conducting block or a metal heat-conducting pipe, or other structures with excellent heat conduction capabilities.

[0041] In some examples, such as Figure 3 and Figure 5 As shown, the first part of the pipeline includes a third pipeline 61 with a second pump body 611. The second water outlet of the cold water tank 40 is connected to the first water outlet 12 through the third pipeline 61. Thus, with the above structural arrangement, when the first water outlet 12 is opened, water from the cold water tank 40 can be drawn out of the first water outlet 12 through the third pipeline 61 to provide room temperature or cold water for drinking. Simultaneously, the second pump body 611 increases the flow rate of water in the third pipeline 61, allowing the water to flow out of the first water outlet 12 more quickly.

[0042] In some examples, such as Figure 3 and Figure 5As shown, the second part of the pipeline includes a fourth pipeline 62 with a third pump body 621. The water inlet of the cold water tank 40 is connected to the water outlet of the buffer tank 20 through the fourth pipeline 62. Thus, with the above structural arrangement, when the cold water tank 40 needs to be replenished, water from the buffer tank 20 can be diverted to the cold water tank 40 through the fourth pipeline 62. Simultaneously, the third pump body 621 can increase the flow velocity of the water in the fourth pipeline 62, allowing the water to flow into the cold water tank 40 more quickly through the fourth pipeline 62.

[0043] In some examples, such as Figure 3 and Figure 5 As shown, the third part of the piping includes a fifth pipe 63 and a sixth pipe 64 with a fourth pump body 641. The return port of the cold water tank 40 is connected to the water outlet of the refrigerator body 30 through the fifth pipe 63, and the third water outlet of the cold water tank 40 is connected to the water inlet of the refrigerator body 30 through the sixth pipe 64. Thus, through the above structural arrangement, on the one hand, the fifth pipe 63 allows the remaining cold water during the ice-making process of the refrigerator body 30 to be returned to the cold water tank, ensuring that the cold water in the cold water tank 40 is always kept at a low temperature (generally about 5°C to 10°C). On the other hand, the sixth pipe 64 allows the refrigerator body 30 to replenish the cold water required for ice making in a timely manner through the water flow in the cold water tank 40, thereby achieving a rapid ice-making process. Simultaneously, the fourth pump body 641 can increase the flow rate of water in the sixth pipe 64, allowing water to flow into the refrigerator body 30 more quickly through the sixth pipe 64.

[0044] In some examples, such as Figure 3 and Figure 5 As shown, the main pipeline assembly 60 also includes a water inlet pipe 65 with a control valve 651, and the water inlet of the buffer tank 20 is connected to an external water supply device through the water inlet pipe 65. Thus, with the above structural arrangement, when this ice-making water dispenser 1 is placed horizontally against the wall along its long side in the kitchen, it can be used through the water inlet pipe 65 connected to an external water supply device.

[0045] It should be noted that the water supply device in this example is preferably an RO machine (Reverse Osmosis Water Purifier) ​​to ensure that the water in the buffer tank 20 is purer and free of impurities, making it more suitable for drinking. In some examples, such as Figure 3 and Figure 5 As shown, the buffer water tank 20 includes a water tank body 21 with a water tank opening and a water tank cover 22 that movably covers the water tank opening. Thus, with the above structural arrangement, the water tank cover 22 of the buffer water tank 20 can be directly opened for manual water dispensing. In this case, the ice-making water dispenser 1 can be placed in locations such as living rooms or bedrooms where it is inconvenient to connect a water supply device.

[0046] The technical means disclosed in this application are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
