Description

Technical Field

[0001] This utility model relates to the field of drinking water treatment technology, and specifically discloses a quick-cooling water dispenser. Background Technology

[0002] Instant cooling devices for drinking water belong to the field of household appliance technology, and specifically relate to a rapid cooling device capable of providing low-temperature drinking water. Currently, in homes, offices, and public places, meeting users' immediate need for low-temperature drinking water is mainly achieved in two ways: First, by using traditional refrigerators, freezers, or other equipment to pre-cool bottled or jug-sized water. This method utilizes the low-temperature environment inside the refrigerator to cool the water as a whole, requiring several hours to reach drinking temperature. Second, some instant hot water dispensers integrate a cooling function, typically using a built-in semiconductor cooling chip or a small compressor cooling system to directly cool the drinking water stored in the built-in water tank.

[0003] However, the aforementioned existing technologies have significant limitations in practical applications. First, pre-refrigeration cannot achieve "instant cooling," requiring users to wait passively and failing to meet the immediate need for readily available water. Furthermore, the refrigeration time and temperature are difficult to control precisely, posing a risk of over-freezing leading to water freezing and packaging breakage. Second, most existing water dispensers with cooling functions use a method of cooling the entire water storage container. The initial cooling time is long, and after continuous water dispensing, the water temperature fluctuates significantly after the cold water level decreases and is replenished with room-temperature purified water, making it difficult to continuously and stably supply low-temperature drinking water at a constant temperature. Simultaneously, this method results in frequent start-stop cycles, low energy efficiency, and uneven temperature distribution. Utility Model Content

[0004] This utility model proposes a rapid-cooling water dispenser that eliminates user waiting time, provides precise temperature control, effectively avoids the risk of water freezing, ensures the reliability and safety of equipment operation, and can continuously and stably supply cold water at a constant temperature, overcoming the shortcomings of traditional equipment with large water temperature fluctuations.

[0005] This utility model is implemented as follows: a quick-cooling water dispenser includes:

[0006] A refrigeration system, comprising a compressor, a condenser, and a refrigeration coil connected in sequence by pipes to form a loop;

[0007] A constant temperature medium tank is used to contain liquid water medium, and the refrigeration coil is immersed in the water medium;

[0008] The temperature control system includes a thermostat installed in the constant temperature medium chamber. The thermostat is electrically connected to the compressor and is used to detect the water medium temperature and control the start and stop of the compressor to maintain the water medium temperature within a preset low temperature range.

[0009] The heat exchange output system includes a drinking water coil immersed in the water medium in the constant temperature medium tank. The inlet of the drinking water coil is used to connect to room temperature drinking water, and its outlet is used to output low temperature drinking water cooled by heat exchange.

[0010] A stirring mechanism is provided inside the constant temperature medium tank to stir the water medium to make its temperature uniform.

[0011] In a preferred embodiment of this invention, the cooling coil of a water dispenser is made of a heat-conducting metal tube and is coiled and distributed inside the constant temperature medium box.

[0013] In a preferred embodiment of this invention, a quick-cooling water dispenser is described, wherein the stirring mechanism is an electric stirrer with blades extending into the interior of the constant-temperature medium tank.

[0014] As a preferred embodiment of the quick-cooling water dispenser of this utility model, the preset low temperature range of the temperature control system is 2℃ to 10℃.

[0015] In a preferred embodiment of this invention, the water medium in the constant temperature medium tank is pure water.

Precise temperature control effectively avoids the risk of water freezing, ensuring the reliability and safety of equipment operation. The simple overall structure not only reduces manufacturing costs and failure rates but also improves system energy efficiency through efficient cold storage and heat exchange. Furthermore, it provides a continuous and stable supply of cold water at a constant temperature, overcoming the shortcomings of traditional equipment with large water temperature fluctuations and significantly enhancing the user experience.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-3 A quick-cooling water dispenser, comprising:

[0025] The refrigeration system includes a compressor 1, a condenser 2, and a refrigeration coil 6 connected in sequence by pipes to form a loop;

[0026] Thermostatic medium tank 4 is used to contain liquid water medium, and the cooling coil 6 is immersed in the water medium;

[0027] The temperature control system includes a temperature controller 3 installed in the constant temperature medium box 4. The temperature controller 3 is electrically connected to the compressor 1 and is used to detect the water medium temperature and control the start and stop of the compressor 1 to maintain the water medium temperature within a preset low temperature range.

[0028] The heat exchange output system includes a drinking water coil 7 immersed in a water medium in a constant temperature medium box 4. The inlet of the drinking water coil 7 is used to connect to room temperature drinking water, and its outlet is used to output low temperature drinking water cooled by heat exchange.

[0029] And a stirring mechanism 5, which is set in a constant temperature medium box 4, is used to stir the water medium to make its temperature uniform.

[0030] In this embodiment: First, the refrigeration system, consisting of compressor 1, condenser 2, and refrigeration coil 6, operates continuously. The refrigerant evaporates in the refrigeration coil 6, which is immersed in the water medium in the constant temperature medium tank 4, directly and extensively absorbing heat from the water medium, thus creating a constant low-temperature environment. Simultaneously, the thermostat 3 monitors the water medium temperature in real time and controls the start and stop of compressor 1, precisely maintaining the water temperature within a preset range (e.g., 2-10℃). The stirring mechanism 5 continuously agitates the water medium, effectively eliminating temperature differences within the tank and ensuring uniform distribution of cooling capacity, which forms the basis for stable cooling. When a user needs cold water, room-temperature drinking water is introduced into the drinking water coil 7, which is also immersed in the constant temperature medium tank 4. The instant it flows within the coil, it completes efficient heat exchange with the external low-temperature water medium, thereby achieving an instant cooling effect without waiting, solving the problems of slow response and large temperature fluctuations in traditional methods.

[0031] As a technical optimization of this utility model, the cooling coil 6 is made of a heat-conducting metal tube and is coiled and distributed inside the constant temperature medium box 4.

[0032] In this embodiment, the cooling coil 6 is made of heat-conducting metal tubes and is coiled and distributed, which increases the contact area between the cooling coil 6 and the water medium. This allows the cooling capacity generated by the cooling system to be transferred to the water medium in the entire constant temperature medium box 4 more quickly and evenly, thereby improving the cooling efficiency of the system, shortening the initial cooling time, and further ensuring the uniformity of the temperature field inside the box.

[0033] As a technical optimization of this utility model, the drinking water coil 7 is made of a heat-conducting metal tube and is coiled into a spiral coil structure.

[0034] In this embodiment, the drinking water coil 7 is made of a heat-conducting metal tube and coiled into a spiral structure. This extends the flow path and residence time of drinking water in the low-temperature water medium, ensuring that the flowing drinking water can fully exchange heat with the refrigerant, thereby guaranteeing that the outlet water temperature can stably reach the preset low-temperature requirement and avoiding temperature failure due to insufficient heat exchange.

[0035] As a technical optimization of this utility model, the stirring mechanism 5 is an electric stirrer, whose blades extend into the interior of the constant temperature medium box 4.

[0036] In this embodiment, the stirring mechanism 5 is an electric stirrer, and the blades extend directly into the water inside the constant temperature medium tank 4. Through the mechanical rotation of the blades, the water medium is forced to flow, which can eliminate the problem of uneven water temperature between the upper and lower layers caused by the difference in density between hot and cold.

[0037] As a technical optimization of this utility model, the preset low temperature range of the temperature control system is 2℃ to 10℃.

[0038] In this embodiment, by limiting the preset low temperature range of the temperature control system to 2°C to 10°C, the risk of ice forming inside the water dispensing coil 7 is avoided. This satisfies the user's demand for a cool drinking experience while preventing pipe blockage or damage caused by icing, thus improving the reliability and safety of the equipment.

[0039] As a technical optimization of this utility model, the water medium in the constant temperature medium box 4 is pure water.

[0040] In this embodiment: Pure water has a high specific heat capacity, making it an excellent heat (cold) storage medium. It is also non-toxic, harmless, and inexpensive, enabling the constant temperature medium box 4 to store a large amount of cold energy, which can play an energy buffering role. Even under conditions of frequent water intake, it can effectively reduce the number of times the compressor 1 starts and stops, thereby improving energy efficiency and equipment lifespan.

[0041] The working principle and usage process of this utility model are as follows: After the equipment is powered on and started, the compressor 1 begins to work, compressing the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas and discharging it into the condenser 2. Inside the condenser 2, the refrigerant dissipates heat to the outside air and condenses into a medium-temperature, high-pressure liquid. Subsequently, this liquid refrigerant flows into the refrigeration coil 6, which is completely immersed in the water medium in the constant-temperature medium tank 4. Inside the refrigeration coil 6, the pressure and temperature of the refrigerant further decrease and it begins to evaporate, absorbing a large amount of heat from the surrounding water medium, causing its temperature to drop. The thermostat 3, located inside the constant-temperature medium tank 4, monitors the water medium temperature in real time. When the temperature is below the set lower limit, the compressor 1 is controlled to stop running. When the temperature rises back to the set upper limit, the compressor 1 is restarted. This cycle is repeated to precisely control the temperature of the water medium within the preset range. During this process, the stirring mechanism 5 continues to operate, stirring the water medium to keep the temperature of each point uniform. When the user takes water, room temperature drinking water enters the drinking water coil 7, which is also immersed in the low temperature water medium, from the inlet. During the flow through the coil, the drinking water undergoes sufficient heat exchange with the external low temperature water medium through the pipe wall and is rapidly cooled. Finally, the low temperature drinking water with a suitable temperature flows out from the outlet.
