Description

Technical Field

[0001] This utility model belongs to the field of cooling equipment technology and relates to a rapid ice-making water machine. 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 an under-sink water purifier (application number: CN106629876A), comprising a water purification component and an ice tank. The water purification component has a water inlet, a room temperature water end, and a cold water end. The water inlet of the water purification component is connected to a tap water pipe. The ice tank has a water inlet, a water outlet, and a one-way valve. The water inlet is connected to the cold water end via the one-way valve, and the one-way valve is located at the water inlet of the ice tank. The water outlet is equipped with a water valve.

[0004] The above-mentioned under-sink air purifier has the following shortcomings during use: In order to ensure sufficient cold water volume, the ice tank of the under-sink air purifier has a large volume. In addition, the ice tank obtains cold water by heat conduction, that is, by the cooling end of the semiconductor being attached to the outer wall of the ice tank to cool the pure water inside the ice tank, resulting in a slow cooling speed of the ice tank. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a rapid ice-water maker. The technical problem this invention aims to solve is how to improve the cooling efficiency of the ice-water maker.

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

[0007] A rapid ice-making water machine includes a housing and a cold water tank and a refrigeration device respectively disposed within the housing. The cold water tank has an inlet and an outlet. The refrigeration device includes a refrigeration tube, which is spirally wound to form a double-layered spiral tube structure. The inner spiral tube is located inside the cold water tank, and the outer spiral tube is spirally coiled on the outer wall of the cold water tank.

[0008] The inner spiral tube of this rapid ice-making water refrigeration pipe is located inside the cold water tank, while the outer spiral tube is spirally coiled on the outer wall of the cold water tank. The inner spiral tube directly cools the room-temperature drinking water in the cold water tank from the inside, while the outer spiral tube cools the side wall of the cold water tank from the outside and indirectly cools the room-temperature drinking water in the cold water tank through heat conduction. This significantly increases the cooling area of ​​the refrigeration pipe and achieves simultaneous internal and external cooling of the room-temperature drinking water in the cold water tank, thereby improving the refrigeration efficiency of the ice-making water refrigeration machine.

[0009] In the aforementioned rapid ice-making water machine, the inner spiral tube of the refrigeration pipe includes a spiral section and a vertical section connected in sequence. The spiral section spirals upwards along the length of the vertical section and coils around the outside of the vertical section. The upper end of the vertical section extends out of the cold water tank and connects to the outer spiral tube of the refrigeration pipe. This design facilitates the processing and manufacturing of the refrigeration pipe and also increases the refrigeration area, thereby improving refrigeration efficiency and effect.

[0010] In the aforementioned rapid ice-making water machine, the spiral section of the inner spiral tube and the outer spiral tube are coaxial and arranged side-by-side, with the spiral directions of the inner spiral tube and the outer spiral tube being opposite. This design maximizes the cooling area of ​​the refrigeration tube itself, facilitates the installation and removal of the refrigeration tube within the cold water tank for synchronized zone cooling, streamlines the manufacturing process of the refrigeration tube, and allows the refrigerant to flow within the refrigeration tube for a period of time under the influence of gravity, thus minimizing flow resistance.

[0011] In the aforementioned rapid ice water maker, the cold water tank has a vertically arranged partition tube. This partition tube is cylindrical and divides the cold water tank into an inner cooling chamber with an inlet and an outer cooling chamber with an outlet. One end of the partition tube is connected to the inner wall of one side of the cold water tank, and the other end of the partition tube is spaced apart from the inner wall of the other side of the cold water tank. The inner spiral tube of the refrigeration pipe is located within the inner cooling chamber, and the outer spiral tube of the refrigeration pipe is spirally coiled around the outer wall of the outer cooling chamber. By setting the partition tube, the cold water tank forms a double-layered cooling chamber with internal and external connections only at one end of the partition tube. This allows the inner spiral tube to directly cool the room-temperature drinking water inside the cold water tank, while the outer spiral tube cools the side wall of the cold water tank from the outside and indirectly cools the room-temperature drinking water inside the cold water tank through heat conduction. This effectively breaks down a large cold water tank into smaller, synchronized cooling zones, thereby further improving the refrigeration efficiency of the ice water maker. In addition, the inlet and outlet of the cold water tank are located on the inner cooling chamber and the outer cooling chamber, respectively. This means that the room temperature drinking water entering the cold water tank needs to be cooled by the inner spiral tube and the outer spiral tube of the refrigeration pipe (i.e., secondary refrigeration) before it can flow out of the cold water tank, resulting in a good cooling effect.

[0012] In the aforementioned rapid ice-making water machine, an insulating shell is provided inside the housing to enclose the cold water tank. The housing has an inlet and an outlet. The inlet pipe of the inlet and the outlet pipe of the outlet both pass through the insulating shell and are connected to the inlet and outlet of the cold water tank, respectively. The insulating shell serves two purposes: firstly, it insulates the cold water tank located inside the insulating shell; secondly, it isolates the cold water tank from the outside environment, minimizing or preventing condensation caused by temperature differences, thereby extending the service life of the cold water tank and the rapid cooling ice-making water machine.

[0013] In the aforementioned rapid ice maker, the refrigeration unit further includes a compressor and a condenser with a fan, both housed within and connected to the casing. 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 cold water 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 ventilation holes. The partition separates the compressor and condenser from the cold water tank. By raising the bottom of the casing with the raised blocks, and through the combined effect of the fan and the ventilation holes on the bottom and side walls, the heat generated by the compressor and condenser can be dissipated more quickly to the outside of the casing, minimizing impact on the cold water tank located on the other side of the partition, thus better preserving the temperature of the cold water in the tank.

[0014] In the aforementioned rapid ice-making water machine, a compressor controller is installed on the partition, a temperature control box is installed on the housing, the temperature control box, the compressor controller, and the compressor are arranged sequentially, the condenser is arranged 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 cold water tank and electrically connected to the temperature control box. The partition serves two purposes. First, it allows for the installation of components such as the compressor controller. The temperature control box, compressor controller, and compressor are arranged sequentially, with the condenser adjacent to the compressor controller and the fan positioned between them. This design makes the overall structure of the rapid-cooling chiller compact, with a small overall size and minimal installation space required. Second, the partition separates the compressor and condenser from the liquid storage tank, allowing for better insulation of the chilled water in the tank's cold water pipes. The temperature control probe monitors the water temperature in the cold water tank in real time. Through the coordination of the temperature control box, compressor controller, compressor, condenser, fan, and refrigeration pipes, the water temperature in the cold water pipes of the liquid storage tank can be better maintained within a preset range.

[0015] Compared with existing technologies, the advantages of this rapid ice water maker are as follows: The inner spiral tube of the refrigeration pipe of this rapid ice water maker is located inside the cold water tank, and its outer spiral tube is spirally coiled on the outer wall of the cold water tank. The inner spiral tube directly cools the room temperature drinking water in the cold water tank from the inside, while the outer spiral tube cools the side wall of the cold water tank from the outside and indirectly cools the room temperature drinking water in the cold water tank through heat conduction. This greatly increases the cooling area of ​​the refrigeration pipe and realizes simultaneous internal and external cooling of the room temperature drinking water in the cold water tank, thereby improving the cooling efficiency of the ice water maker.

[0022] 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.

[0023] Example 1

[0024] A rapid ice water maker, as described in the following text Figure 1-4 The device includes a housing 1, a cold water tank 2 and a refrigeration device 3 respectively disposed within the housing 1. The cold water tank 2 has an inlet 2a and an outlet 2b. The refrigeration device 3 includes a refrigeration tube 3a. The refrigeration tube 3a is wound in a spiral manner to form a double-layered spiral tube structure. The inner spiral tube 3a1 of the refrigeration tube 3a is located inside the cold water tank 2, and the outer spiral tube 3a2 of the refrigeration tube 3a is spirally coiled on the outer side wall of the cold water tank 2.

[0025] Reference Figure 4 Specifically, the inner spiral tube 3a1 of the refrigeration tube 3a includes a spiral section 3a11 and a vertical section 3a12 connected in sequence.

[0026] In this embodiment, the spiral segment 3a11 of the inner spiral tube 3a1 and the outer spiral tube 3a2 are coaxial and arranged side by side, and the spiral directions of the spiral segment 3a11 of the inner spiral tube 3a1 and the outer spiral tube 3a2 are opposite.

[0027] Reference Figure 4Furthermore, the cold water tank 2 has a vertically arranged partition tube 2c. The partition tube 2c is cylindrical and divides the cold water tank 2 into an inner cooling chamber 2d with the water inlet 2a and an outer cooling chamber 2e with the water outlet 2b.

The inner spiral tube 3a1 of the refrigeration tube 3a is located in the inner cooling chamber 2d, and the outer spiral tube 3a2 of the refrigeration tube 3a is spirally coiled on the outer wall of the outer cooling chamber 2e.

[0028] Reference Figure 4 In this embodiment, the baffle 2c is preferably integrally formed on the inner top wall of the cold water tank 2. The side wall of the baffle 2c is adjacent to the side wall of the cold water tank 2, and there is a gap between the lower end of the baffle 2c and the inner bottom wall of the cold water tank 2. The inlet 2a and the outlet 2b are both respectively located on the top wall of the cold water tank 2. It should be noted that the positions of the inlet 2a and the outlet 2b can be interchanged. That is, the inlet 2a can be located on the inner cooling chamber 2d, and the outlet 2b can be located on the outer cooling chamber 2e; or the inlet 2a can be located on the outer cooling chamber 2e, and the outlet 2b can be located on the inner cooling chamber 2d. Alternatively, the baffle 2c can also be integrally formed on the inner bottom wall of the cold water tank 2. In this case, the inlet 2a and the outlet 2b are both respectively located on the bottom wall of the cold water tank 2.

[0029] Reference Figure 2 Furthermore, the housing 1 is provided with an insulation shell 4 that wraps around the outside of the cold water tank 2. The housing 1 has a water inlet 1a and a water outlet 1b. The water inlet pipe 1a1 on the water inlet 1a and the water outlet pipe 1b1 on the water outlet 1b both pass through the insulation shell 4 and are respectively connected to the water inlet 2a and the water outlet 2b on the cold water tank 2.

[0030] Reference Figure 2 and Figure 3 Specifically, the refrigeration device 3 also includes a compressor 3b and a condenser 3c with a fan 3c1, both disposed inside and connected to the housing 1. A partition 5 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 5, and the cold water tank 2 is disposed on the other side of the partition 5. The bottom of the housing 1 has several raised blocks 1c, and the bottom wall and side wall of the housing 1 have several heat dissipation holes 1d.

[0031] Reference Figure 2 and Figure 3More specifically, a compressor controller 3d is installed on the partition 5, a temperature control box 3e is installed on the housing 1, the temperature control box 3e, the compressor controller 3d and the compressor 3b are arranged vertically in sequence, the condenser 3c is arranged adjacent to the compressor controller 3d, and the fan 3c1 is located between the condenser 3c and the compressor controller 3d. A temperature control probe 3f is inserted into the cold water tank 2 and is electrically connected to the temperature control box 3e.

[0032] The working principle of this rapid ice maker is explained below:

[0033] When in use, install this rapid ice water maker in the cabinet under the kitchen sink. Connect the water inlet 1a on the casing 1 of this rapid ice water maker to the household water purifier, which is also located in the cabinet under the kitchen sink. Connect the water outlet 1b on the casing 1 to the cold water drinking faucet. The room temperature drinking water provided by the household water purifier is stored in the cold water tank 2. The refrigeration device 3 cools the room temperature drinking water in the cold water tank 2 to obtain cold water at a suitable temperature and continues to store it in the cold water tank 2. The insulation shell 4 keeps the cold water in the cold water tank 2 warm.

[0034] When a user needs to drink cold water, the user only needs to turn on the cold water tap, and the cold water in the cold water tank 2 will flow into the user's drinking cup through the cold water tap;

[0035] When the user stops drawing cold water, some of the cold water in the cold water tank 2 is consumed. The household water purifier will continue to supply room temperature drinking water to the cold water tank 2. At this time, the temperature control probe 3f detects that the water temperature in the cold water tank 2 has risen. Then, the compressor controller 3d controls the compressor 3b to work, the condenser 3c and the fan 3c1 start. Finally, the refrigeration pipe 3a cools the newly added room temperature drinking water in the cold water tank 2 to obtain cold water at a suitable temperature and continues to store it in the cold water tank 2. When the temperature control probe 3f detects that the water temperature in the cold water tank 2 has reached the preset temperature, the compressor 3b, condenser 3c and fan 3c1 stop working. The insulation shell 4 keeps the cold water in the cold water tank 2 warm for the user's next use. This cycle continues, which not only stores and provides a sufficient amount of cold water for the user's current drinking, but also provides sufficient time for the refrigeration device 3 to cool the newly added room temperature drinking water in the cold water tank 2. This ensures that the rapid ice maker always has a sufficient amount of cold water at a preset temperature, thus providing a rapid ice maker.
