Description

Technical Field

[0001] This utility model belongs to the field of cooling equipment technology and relates to a chiller for rapid cooling. 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: 201610854424.3), comprising a water purification component and an ice tank. The water purification component has an inlet, a room temperature water end, and a cold water end. The inlet of the water purification component is connected to a tap water pipe. The ice tank has an inlet, an outlet, and a one-way valve. The inlet is connected to the cold water end via the one-way valve, and the one-way valve is located at the inlet of the ice tank. The 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-cooling chiller. The technical problem this invention aims to solve is how to improve the cooling efficiency of the chiller.

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

[0007] A rapid-cooling chiller includes a housing and a cold water tank and a refrigeration device respectively disposed within the housing. The cold water tank has a vertically arranged partition tube, which 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 refrigeration device includes a refrigeration pipe disposed within the cold water tank. The refrigeration pipe is spirally wound to form a double-layered spiral tube structure, with the inner spiral tube located within the inner cooling chamber and the outer spiral tube located within the outer cooling chamber.

[0008] This rapid-cooling chiller's cold water tank utilizes a partition tube to create a double-layered cooling chamber, with the inner and outer chambers connected only at one end. Simultaneously, the refrigeration pipes within the tank feature a double-layered spiral tube structure, significantly increasing the cooling area. The inner spiral tube cools the ambient temperature drinking water in the inner cooling chamber, while the outer spiral tube cools the ambient temperature drinking water in the outer cooling chamber. This effectively breaks down a large cold water tank into smaller, synchronized cooling zones, thus improving the chiller's cooling efficiency. Furthermore, the inlet and outlet of the cold water tank are located in the inner and outer cooling chambers respectively, requiring ambient temperature drinking water entering the tank to undergo secondary cooling (i.e., cooling through both the inner and outer spiral tubes) before exiting, resulting in superior cooling performance.

[0009] In the aforementioned rapid cooling chiller, the inner and outer spiral tubes of the refrigeration pipe are coaxial and arranged side-by-side. This maximizes the cooling area of ​​the refrigeration pipe and facilitates its installation and removal within the chilled water tank, enabling synchronized cooling in different zones.

[0010] In the aforementioned rapid cooling chiller, the inner and outer spiral tubes of the refrigeration pipe have opposite spiral directions, and both ends of the refrigeration pipe are located on the same side of the cold water tank. This facilitates the processing and manufacturing of the refrigeration pipe and allows the refrigerant to flow within the refrigeration pipe for a period of time under the influence of gravity, thus reducing excessive flow resistance.

[0011] In the aforementioned rapid cooling chiller, 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 encloses the cold water tank and isolates it 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 chiller.

[0012] In the aforementioned rapid cooling chiller, the refrigeration unit further includes a compressor and a condenser equipped 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 chilled water tank is located on the other side. The casing has several ventilation holes. The partition isolates the compressor and condenser from the chilled water tank. Simultaneously, the fan and ventilation holes ensure that the heat generated by the compressor and condenser is dissipated from the casing in a timely manner, minimizing any impact on the chilled water tank located on the other side of the partition, thereby better preserving the temperature of the chilled water in the tank.

[0013] In the above-mentioned rapid cooling chiller, 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 is 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.

[0014] In the aforementioned rapid cooling chiller, the bottom of the housing has several raised blocks, and several heat dissipation holes are distributed on the bottom and side walls of the housing. By setting the raised blocks, the bottom of the housing is raised, and the heat dissipation holes on the bottom and side walls of the housing allow the heat generated by the compressor and condenser to be dissipated to the outside of the housing more promptly, minimizing the impact on the chilled water tank inside the housing, thereby better preserving the temperature of the chilled water in the tank.

[0015] Compared with existing technologies, the advantages of this rapid cooling chiller are as follows: The chilled water tank of this rapid cooling chiller is configured with a partition tube, which forms a double-layered cooling chamber with an inner and outer layer connected only at one end of the partition tube. At the same time, the refrigeration pipes set in the chilled water tank are double-layered spiral tubes with an inner and outer layer structure that matches the structure of the chilled water tank. This greatly increases the cooling area of ​​the refrigeration pipes, and allows the inner spiral tubes of the refrigeration pipes to cool the room temperature drinking water in the inner cooling chamber, while the outer spiral tubes of the refrigeration pipes can cool the room temperature drinking water in the outer cooling chamber. This realizes the division of a large chilled water tank into smaller parts, with synchronous cooling in different areas, thereby improving the cooling efficiency of the chiller.

[0016] 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.

Detailed Implementation

[0023] 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.

[0024] A rapid-cooling chilled water machine, as described above. Figure 1-5 The device includes a housing 1, a cold water tank 2, and a refrigeration device 3, both disposed within the housing 1. The cold water tank 2 has a vertically arranged partition tube 2a. The partition tube 2a is cylindrical and divides the cold water tank 2 into an inner cooling chamber 2b with an inlet 2d and an outer cooling chamber 2c with an outlet 2e.

The inner spiral tube 3a1 of the refrigeration tube 3a is located in the inner cooling chamber 2b, and the outer spiral tube 3a2 of the refrigeration tube 3a is located in the outer cooling chamber 2c.

[0025] Reference Figure 4 In this embodiment, the baffle 2a is preferably integrally formed on the inner top wall of the cold water tank 2, and there is a gap between the lower end of the baffle 2a and the inner bottom wall of the cold water tank 2. The inlet 2d and the outlet 2e are both respectively located on the top wall of the cold water tank 2. It should be noted that the positions of the inlet 2d and the outlet 2e can be interchanged. That is, the inlet 2d can be located on the inner cooling chamber 2b, and the outlet 2e can be located on the outer cooling chamber 2c; or the inlet 2d can be located on the outer cooling chamber 2c, and the outlet 2e can be located on the inner cooling chamber 2b. Alternatively, the baffle 2a can also be integrally formed on the inner bottom wall of the cold water tank 2, in which case the inlet 2d and the outlet 2e are both respectively located on the bottom wall of the cold water tank 2.

[0026] In this embodiment, the inner spiral tube 3a1 and the outer spiral tube 3a2 of the refrigeration tube 3a are preferably coaxial and arranged side by side. Further, the inner spiral tube 3a1 and the outer spiral tube 3a2 of the refrigeration tube 3a have opposite spiral directions, and both ends of the refrigeration tube 3a are located on the same side of the cold water tank 2.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 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 2d and the water outlet 2e on the cold water tank 2.

[0028] Reference Figure 2 and Figure 3Specifically, the refrigeration device 3 further includes a compressor 3b and a condenser 3c with a fan 3c1, both disposed within and connected to the housing 1. A partition 6 is vertically connected to the bottom of the housing 1. The condenser 3c and compressor 3b are disposed on one side of the partition 6, and the cold water tank 2 is disposed on the other side of the partition 6. The housing 1 has a plurality of heat dissipation holes 1d. In this embodiment, preferably, the bottom of the housing 1 has a plurality of raised blocks 1c, and the plurality of heat dissipation holes 1d are distributed on the bottom wall and side wall of the housing 1.

[0029] Reference Figure 2 and Figure 3 More specifically, a compressor controller 3d is installed on the partition 6, 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 5 is inserted into the cold water tank 2 and is electrically connected to the temperature control box 3e.

[0030] The working principle of this rapid cooling chiller is explained below:

[0031] When in use, install this fast-cooling ice water machine in the cabinet under the kitchen sink. At the same time, connect the water inlet 1a on the shell 1 of this fast-cooling ice water machine to the household water purifier, which is also located in the cabinet under the kitchen sink. Connect the water outlet 1b on the shell 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 room temperature drinking water in the cold water tank 2 is cooled by the refrigeration device 3 to obtain cold water at a suitable temperature and is stored in the cold water tank 2. The insulation shell 4 keeps the cold water in the cold water tank 2 warm.

[0032] 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;

[0033] 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 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 to 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 detects that the water temperature in the cold water tank 2 has reached the preset temperature, the compressor 3b, the condenser 3c and the 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 chilled water machine always has a sufficient amount of cold water at a preset temperature, thus providing a fast-cooling chilled water machine.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
