Description

Technical Field

[0001] This utility model belongs to the field of cooling equipment technology and relates to a water cooling device. Background Technology

[0002] Household water purifiers are mainly used to purify tap water in the home so that it can be drunk directly. Among them, under-sink water purifiers are increasingly used by families because they can be directly connected to the tap water pipe. However, existing under-sink water purifiers are mainly used to provide room temperature drinking water. When users want to drink ice water, they can only put the room temperature drinking water in the refrigerator to cool it down, which is inconvenient.

[0003] To address the aforementioned shortcomings, Chinese patent literature discloses a cooling water tank, a water purifier equipped with the cooling water tank, and a method for manufacturing the cooling water tank (application number: 202080084137.3). The cooling water tank may include a tank body, a foaming shell, and a foaming insulation component. The tank body has a water-containing space inside. A cover assembly is located on the upper part of the tank body. The cover assembly may include: a tank cover, which is combined with the tank body; a cold water pipe, which is combined with the tank cover; an evaporation pipe; and a stirring unit.

[0004] The above-mentioned cooling water tank has the following shortcomings during use: the cold water pipe and evaporator pipe of the cooling water tank are both cylindrical structures, and the evaporator pipe is located inside the cold water pipe. When the main body of the water tank is rectangular or especially flat, due to the limited installation space, the coiling diameter of both the cylindrical cooling pipe and evaporator pipe is small, and the coiling diameter of the evaporator pipe located inside is even smaller, resulting in low cooling efficiency of the cooling water tank. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a cooling water device. The technical problem this invention aims to solve is how to provide a cooling water device with high cooling efficiency.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A water cooling device includes a housing, a water cooling pipe and a refrigeration device disposed within the housing, the refrigeration device including a refrigeration unit, characterized in that the refrigeration unit is formed by bending a refrigeration tube back and forth to form a sheet-like structure, the water cooling pipe is wound into a square cylindrical structure by spiraling, the housing has a liquid storage tank matching the shape of the water cooling pipe, the water cooling pipe and the refrigeration unit are both disposed within the liquid storage tank, and the refrigeration unit is inserted into the inner side of the water cooling pipe.

[0008] The chilled water pipes of this chilled water device are spirally wound into a square cylindrical structure, making the liquid storage tank, which matches the shape of the chilled water pipes, flat. This requires less installation space and facilitates the miniaturization of the entire chilled water device. At the same time, the refrigeration unit uses refrigeration tubes that are bent back and forth to form a sheet-like structure, which can increase the extension range of the refrigeration unit in a flat and narrow space. This maximizes the refrigeration area of ​​the refrigeration unit within the flat and narrow space, thereby providing a chilled water device with high cooling efficiency.

[0009] In the aforementioned water cooling device, the refrigeration unit has a wave-like structure. Both sides of the refrigeration unit are positioned adjacent to the inner wall of the cold water pipe. The crests of the refrigeration unit extend upwards from the cold water pipe, while the troughs are positioned adjacent to the inner bottom wall of the liquid storage tank. This design makes the shape of the refrigeration unit more regular, facilitating manufacturing. Furthermore, it increases the extension range of the refrigeration unit within a flat, elongated space, thereby increasing the cooling area and providing a water cooling device with high cooling efficiency.

[0010] In the aforementioned water cooling device, the crests and troughs of the refrigeration unit are both elongated U-shaped. This further expands the vertical extension range of the refrigeration unit and increases its horizontal density, thereby increasing the cooling area of ​​the refrigeration unit and providing a water cooling device with high cooling efficiency.

[0011] In the aforementioned cooling water device, an agitator is installed on the inner bottom wall of the storage tank, located inside the cooling water pipe, and the agitator is vertically adjacent to the trough section of the refrigeration unit. The agitator ensures a uniform temperature of the coolant contained in the storage tank, preventing the coolant at the bottom from freezing. After the agitator stirs the coolant, the cylindrical cooling water pipe facilitates uniform rotation of the coolant. Simultaneously, the vertical proximity of the agitator to the trough section of the refrigeration unit ensures that the coolant makes uniform contact with the refrigeration unit during rotation, thereby better maintaining a uniform temperature of the coolant contained in the storage tank.

[0012] In the aforementioned water cooling device, both the housing and the liquid storage tank are rectangular and flat. This makes the shapes of the housing and the liquid storage tank more regular, reduces the installation space required for the entire device, and facilitates the miniaturization of the entire water cooling device.

[0013] In the aforementioned water cooling device, the refrigeration unit further includes a compressor and a condenser equipped with a fan, both housed within and connected to the casing. The inlet and outlet of the refrigeration unit extend beyond the storage tank and are connected to the condenser and compressor, respectively. A partition is vertically connected to the bottom of the casing. The condenser and compressor are located on one side of the partition, and the storage tank is located on the other side. The bottom of the casing has several raised blocks, and the bottom and side walls of the casing have several heat dissipation holes. The partition isolates the compressor and condenser from the storage tank. Simultaneously, the fan, raised blocks, and heat dissipation holes ensure that the heat generated by the compressor and condenser is dissipated outside the casing in a timely manner, minimizing any impact on the storage tank located on the other side of the partition. This allows for better insulation of the cold water in the storage tank's cooling water pipes.

[0014] In the aforementioned chilled water device, a compressor controller is mounted on the partition, and a temperature control box is mounted on the housing. The temperature control box, compressor controller, and compressor are arranged vertically in sequence. The condenser is adjacent to the compressor controller, and the fan is located between the condenser and the compressor controller. A temperature control probe is inserted into the liquid storage tank and electrically connected to the temperature control box. The partition serves two purposes: firstly, it allows for the installation of components such as the compressor controller; secondly, the vertical arrangement of the temperature control box, compressor controller, and compressor, with the condenser adjacent to the compressor controller and the fan located between them, results in a compact overall structure, small size, and minimal installation space required. Thirdly, the partition isolates the compressor and condenser from the liquid storage tank, allowing for better insulation of the chilled water in the tank's chilled water pipes. The temperature control probe monitors the water temperature in the tank in real time. Through the coordination of the temperature control box, compressor controller, compressor, condenser, fan, and refrigeration unit, the water temperature in the tank's chilled water pipes is effectively maintained within a preset range.

[0015] In the aforementioned cold water device, the casing has an inlet and an outlet. The inlet and outlet of the cold water pipe extend out of the storage tank and are connected to the inlet and outlet respectively. The refrigeration unit and the cold water pipe are arranged adjacent to each other at their protruding portions from the storage tank. This ensures that the portion of the water path exposed in the storage tank—the inlet and outlet of the cold water pipe—can still be cooled, allowing room-temperature drinking water to be pre-cooled before entering the storage tank. This facilitates the subsequent cooling of the cold water pipe within the storage tank and prevents the cold water from heating up due to the large temperature difference between the inside and outside of the storage tank after flowing out and before being collected by the user, thus affecting the drinking taste.

[0016] In the aforementioned water chiller, there are two refrigeration units, whose refrigeration pipes are welded or integrally formed and connected, and the two refrigeration units are stacked sequentially with intervals between them. This allows for maximizing the cooling area of ​​the refrigeration units within a flat, elongated space, thereby providing a water chiller with high cooling efficiency.

[0017] Compared with existing technologies, the advantages of this chilled water device are as follows: the chilled water pipes of this chilled water device are wound into a square cylindrical structure in a spiral manner, so that the liquid storage tank that matches the shape of the chilled water pipes is flat as a whole, requiring less installation space, which is conducive to the miniaturization of the entire chilled water device. At the same time, the refrigeration unit adopts a refrigeration tube that is bent back and forth to form a sheet-like structure, which can increase the extension range of the refrigeration unit in a flat and narrow space, thereby maximizing the refrigeration area of ​​the refrigeration unit in a flat and narrow space, thus providing a chilled water device with high cooling efficiency.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] Example 1

[0027] A water cooling device, as described above Figure 1-5 The device includes a housing 1, a cold water pipe 2, and a refrigeration device 3 disposed within the housing 1. The refrigeration device 3 includes a refrigeration unit. The refrigeration unit is formed by bending a refrigeration pipe 3a back and forth to form a sheet-like structure. The cold water pipe 2 is wound into a square cylindrical structure by spiraling. The housing 1 has a liquid storage tank 1a that matches the shape of the cold water pipe 2. In this embodiment, it is preferred that both the housing 1 and the liquid storage tank 1a are rectangular and flat. The cold water pipe 2 and the refrigeration unit are both disposed within the liquid storage tank 1a, and the refrigeration unit is inserted into the inner side of the cold water pipe 2.

[0028] Reference Figure 3 , Figure 4 and Figure 5 Specifically, the refrigeration unit has a wave-like structure, with both sides of the refrigeration unit adjacent to the inner wall of the cold water pipe 2. The crest 3a1 of the refrigeration unit extends upward from the cold water pipe 2, and the trough 3a2 of the refrigeration unit is adjacent to the inner bottom wall of the liquid storage tank 1a. In this embodiment, preferably, both the crest 3a1 and the trough 3a2 of the refrigeration unit are elongated U-shaped.

[0029] Reference Figure 3 , Figure 4 and Figure 5 Furthermore, an agitator 4 is installed on the inner bottom wall of the liquid storage tank 1a, located inside the cold water pipe 2, and the agitator 4 is arranged vertically adjacent to the trough portion 3a2 of the refrigeration unit.

[0030] Reference Figure 1 More specifically, the refrigeration device 3 further includes a compressor 3b disposed inside and connected to the housing 1 and a condenser 3c with a fan 3c1. The liquid inlet 3a3 and liquid outlet 3a4 of the refrigeration unit extend out of the liquid storage tank 1a and are respectively connected to the condenser 3c and the compressor 3b. A partition 7 is vertically connected to the bottom of the housing 1. The condenser 3c and the compressor 3b are disposed on one side of the partition 7, and the liquid storage tank 1a is disposed on the other side of the partition 7. The bottom of the housing 1 has several raised blocks 8, and the bottom wall and side wall of the housing 1 have several heat dissipation holes 1d.

[0031] Reference Figure 1Furthermore, a compressor controller 3d is installed on the partition 7, and a temperature control box 5 is installed on the housing 1. The temperature control box 5, the compressor controller 3d, and the compressor 3b are arranged sequentially, one above the other. The condenser 3c is arranged adjacent to the compressor controller 3d, and the fan 3c 1 is located between the condenser 3c and the compressor controller 3d. A temperature control probe 6 is inserted into the liquid storage tank 1a and electrically connected to the temperature control box 5.

[0032] Reference Figure 1 More specifically, the housing has a water inlet 1b and a water outlet 1c. The water inlet 2a and the water outlet 2b of the cold water pipe 2 extend out of the liquid storage tank 1a and are connected to the water inlet 1b and the water outlet 1c respectively. The refrigeration unit and the cold water pipe 2 are arranged adjacent to each other at the parts that extend out of the liquid storage tank 1a.

[0033] The working principle of this cooling water device is explained below:

[0034] In use, this cold water device is installed in the cabinet under the kitchen sink. The inlet 1b of the device's housing 1 is connected to a household water purifier also located in the cabinet under the kitchen sink. The outlet 1c of the housing 1 is connected to a cold water faucet, allowing the household water purifier to connect to the cold water faucet via the cold water pipe 2. The storage tank 1a contains coolant. The refrigeration unit located inside the cold water pipe 2 cools the coolant in the storage tank 1a and the drinking water in the cold water pipe 2, thus obtaining cold water at a suitable temperature, which is then stored in the cold water pipe 2. The coolant helps to keep the cold water stored in the cold water pipe 2 warm. When the user needs to drink cold water, they simply turn on the cold water faucet, and the cold water in the cold water pipe 2 flows into the user's drinking cup.

[0035] When the user stops drawing cold water, some of the cold water in cold water pipe 2 is consumed. The household water purifier will continue to supply room temperature drinking water to cold water pipe 2. At this time, the temperature control probe 6 detects that the temperature of the coolant in the liquid storage tank 1a has risen. Then, the compressor controller 3d controls the compressor 3b to work, and the condenser 3c and fan 3c1 start. Finally, the refrigeration unit continues to cool the coolant in the liquid storage tank 1a and the drinking water in cold water pipe 2, and then obtains cold water at a suitable temperature and continues to store it in cold water pipe 2. At this time, the temperature control probe detects that the temperature of the coolant in the liquid storage tank 1a has reached the preset temperature, and the compressor 3b, condenser 3c and fan 3c1 stop working. This cycle continues, so that there is always a certain amount of cold water at a suitable temperature in cold water pipe 2 available for drinking. The chilled water pipe 2 of this chilled water device is wound into a square cylindrical structure by a spiral, so that the liquid storage tank 1a, which matches the shape of the chilled water pipe 2, is flat. This requires less installation space and is conducive to the miniaturization of the entire chilled water device. At the same time, the refrigeration unit is bent back and forth to form a sheet-like structure, which can increase the extension range of the refrigeration unit in the flat and narrow space. This maximizes the refrigeration area of ​​the refrigeration unit in the flat and narrow space, thereby providing a chilled water device with high cooling efficiency.

[0036] It should be noted that this cold water device can not only be installed in the cabinet under the kitchen sink and connected to a household water purifier and a cold water tap, but it can also be used directly to cool various beverages in equipment such as beer vending machines and beverage machines.
