Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to a drinking water device. Background Technology

[0002] Boiled water, cooled to a suitable temperature after boiling, is preferred by most people. Existing ordinary water dispensers only provide cold and hot water. However, as user demands increase, the requirements for water dispensers are also rising. Some water dispensers now offer warm water, which typically heats room temperature water to different temperatures. This warm water is not boiled and is not boiled water, thus failing to meet people's needs.

[0003] While conventional water dispensers already provide hot water, some can also cool the hot water to produce cooled boiled water. This is achieved by drawing hot water from a hot water tank through a pipe, which is then cooled in the pipe. One method involves directing the pipe into a cold water tank, allowing the hot water in the pipe to exchange heat with the cold water in the cold tank to produce cooled boiled water. This method involves cooling the hot water in the pipe, but it's an immediate heat exchange; as cooled boiled water is used, the hot water in the pipe is replenished, preventing sufficient contact between the hot and cold water in the tank and limiting the production of large quantities of cooled boiled water in a short time. Another method uses a cooling assembly to cool the pipe, also an immediate heat exchange, but this cooling assembly is more energy-intensive. Utility Model Content

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] See Figures 1 to 7This embodiment provides a drinking water device, including a hot water tank assembly 10 and a warm water tank assembly 20. The hot water tank assembly 10 includes a hot water tank body 11 and a heating assembly. The hot water tank body 11 has a first water inlet 111 and a first hot water outlet 112. The heating assembly is used to heat the water in the hot water tank body 11 to form hot water. The warm water tank assembly 20 includes a warm water tank body 21 and a first cooling assembly 22. The warm water tank body 21 has a second water inlet 211 and a second water outlet 212. The second water inlet 211 is connected to the first hot water outlet 112. The first hot water outlet 112 is used to provide hot water to the second water inlet 211. The first cooling assembly 22 is used to cool the water in the warm water tank body 21.

[0036] By supplying hot water from the hot water tank 11 to the warm water tank 21, and using the first cooling component 22 to cool the water in the warm water tank 21, the hot water is cooled, thus producing cooled boiled water. The warm water tank 21 can store cooled boiled water, ensuring a stable temperature and allowing users to quickly obtain a large amount of cooled boiled water, reducing energy consumption. By using the first cooling component 22 to cool the warm water tank 21, there is no need to install excessively long pipelines, reducing costs.

[0037] In this embodiment, the first cooling component 22 includes a cooling fan, which is disposed on at least one side of the warm water tank 21 and blows air towards the outer surface of the warm water tank 21. The cooling fan cools the warm water tank 21, allowing the water inside to reach the desired temperature, thus reducing cost and energy consumption. In other embodiments, the first cooling component 22 includes a compressor refrigeration system or a semiconductor refrigeration chip. The first cooling component 22 can be disposed on the outside or inside of the warm water tank 21, depending on its structure; no limitation is made here.

[0038] The principle of a cooling fan is that a motor drives the fan blades to rotate, generating airflow. This airflow blows across the surface of a heated object, accelerating heat exchange (convective heat transfer), blowing away the hot air, and introducing cooler air, thereby lowering the temperature of the object and its surrounding environment. The cooling fan itself does not cool; it merely accelerates airflow and promotes the dissipation of existing heat. Therefore, compared to existing compressor refrigeration systems or thermoelectric coolers, it has lower cost and energy consumption.

[0039] The warm water tank assembly 20 also includes a first temperature sensor 23, which is disposed inside the warm water tank 21 and is communicatively connected to the first cooling assembly 22. The first cooling assembly 22 turns on or off based on the temperature value obtained by the first temperature sensor 23. For example, the first cooling assembly 22 includes a cooling fan; the cooling fan turns on when the temperature value obtained by the first temperature sensor 23 is greater than or equal to a first temperature setpoint, and turns off when the temperature value obtained by the first temperature sensor 23 is less than the first temperature setpoint. The first temperature setpoint can be set according to actual needs. For example, the cooling fan turns on when the temperature value obtained by the first temperature sensor 23 is greater than or equal to 25°C, and turns off when the temperature value obtained by the first temperature sensor 23 is less than 25°C.

[0040] For a warm water tank 21, one, two, or more cooling fans can be installed. For example, one cooling fan is installed and located on one side of the warm water tank 21. Alternatively, two cooling fans are installed and located on adjacent sides of the warm water tank 21, such that the air outlet directions of the two cooling fans are perpendicular, thereby promoting airflow over a wide area and enhancing heat dissipation.

[0041] In this embodiment, the cooling fan exhausts air along a first direction. In a first plane perpendicular to the first direction, the projection of the warm water tank 21 onto the first plane lies within the projection of the cooling fan onto the first plane. The cooling fan is large enough to completely cover the warm water tank 21, facilitating heat dissipation from all sides, improving heat dissipation efficiency, and accelerating the cooling rate of the water inside the warm water tank 21. Figure 3 The first direction is indicated by arrow O1.

[0042] The warm water tank assembly 20 also includes a first water outlet pipe 24 and a switch valve 25. The first water outlet pipe 24 is located on the outside of the warm water tank body 21 and communicates with the second water outlet 212. The switch valve 25 is located on the first water outlet pipe 24. The first water outlet pipe 24 is used to guide the water inside the warm water tank body 21 to flow out. When the switch valve 25 is open, the water inside the warm water tank body 21 can flow out. When the switch valve 25 is closed, the water inside the warm water tank body 21 cannot flow out.

[0043] In some embodiments, the switching valve 25 is a mechanical valve, which can be manually opened or closed by the user. In some embodiments, the switching valve 25 is an electrically controlled valve, and the warming tank assembly 20 further includes a second temperature sensor 26, which is disposed on the first water outlet pipe 24 and is communicatively connected to the switching valve 25. The switching valve 25 opens or closes according to the temperature value obtained by the second temperature sensor 26. For example, if the temperature value obtained by the second temperature sensor 26 is greater than or equal to a second temperature setting value, the switching valve 25 is closed, and even if the user presses the button to obtain cooled boiled water, the switching valve 25 will be forcibly closed to prevent the user from being scalded by excessively hot water. If the temperature value obtained by the second temperature sensor 26 is less than the second temperature setting value, the switching valve 25 can open. The second temperature setting value can be set according to actual needs. For example, if the temperature value obtained by the second temperature sensor 26 is greater than or equal to 45°C, the switching valve 25 is closed and cannot be opened; if the temperature value obtained by the second temperature sensor 26 is less than 45°C, the switching valve 25 can open.

[0044] The hot water tank assembly 10 also includes a first connecting water pipe 12. One end of the first connecting water pipe 12 is connected to the first hot water outlet 112 of the hot water tank 11, and the other end of the first connecting water pipe 12 is connected to the second water inlet 211 of the warm water tank 21. This allows the second water inlet 211 to supply hot water to the warm water tank 21, and the second water outlet 212 to guide the water out of the warm water tank 21. The hot water tank 11 also has a second hot water outlet 113 for supplying hot water to the user. The heating element can be an existing heating wire.

[0045] The hot water supplied by the hot water tank 11 to the second inlet 211 is at a higher temperature, while the water stored inside the warm water tank 21 is at a lower temperature due to the action of the first cooling component 22. To prevent the newly entering hot water from impacting the water inside the warm water tank 21, for example, a first water guide pipe 27 and a second water guide pipe 28 are arranged vertically inside the warm water tank 21. The second inlet 211 is located at the bottom of the warm water tank 21 and is connected to the first water guide pipe 27, and the second outlet 212 is located at the top of the warm water tank 21 and is connected to the second water guide pipe 28. By setting the first water guide pipe 27 and the second water guide pipe 28, the hot water entering through the second inlet 211 is guided to the top of the warm water tank 21, and the second water guide pipe 28 guides the water at the bottom of the warm water tank 21 to flow outward, achieving hot water on top and cold water on the bottom, thus preventing the hot water from impacting the cold water.

[0046] For example, the first water guide pipe 27 is located between the second water guide pipe 28 and the cooling fan, so that the first water guide pipe 27 is closer to the cooling fan. The hot water guided into the warm water tank 21 from the second water inlet 211 by the first water guide pipe 27 is closer to the cooling fan, thereby improving the heat dissipation efficiency.

[0047] The shape of the warm water tank 21 can be set according to actual needs. For example, the warm water tank 21 is a cylinder or a cuboid.

[0048] A portion of the outer surface of the warm water tank 21 is concave to form a cavity, and the cavities on opposite sides of the warm water tank 21 are interconnected to form a hollow region 213 penetrating the warm water tank 21. By setting the cavity, the surface area of ​​the outer surface of the warm water tank 21 is increased, improving the heat dissipation effect; by interconnecting the cavities on opposite sides of the warm water tank 21 to form a hollow region 213 penetrating the warm water tank 21, airflow can pass through, ensuring the heat dissipation effect.

[0049] The shape of the hollow region 213 can be set according to actual needs. For example, the hollow region 213 can be cylindrical, cuboid, or cross-shaped. The number of hollow regions 213 can be set according to actual needs. For example, multiple hollow regions 213 are spaced apart. For example, the hollow region 213 is cuboid. When multiple hollow regions 213 are provided, the shapes of the multiple hollow regions 213 can be the same or different, and there is no limitation here.

[0050] In this embodiment, the cooling fan blows air in a first direction, which is the direction in which the hollow region 213 penetrates the warm water tank 21, so that the air blown out by the cooling fan can flow fully through the hollow region 213 and make full contact with the outer surface of the warm water tank 21, thereby improving the heat dissipation effect.

[0051] The drinking water device also includes a cold tank assembly 30, which comprises a cold water tank 31 and a second cooling assembly 32. The cold water tank 31 has a third inlet and a third outlet 311, with the third outlet 311 connected to the first inlet 111. The second cooling assembly 32 is located on the outside of the cold water tank 31 to cool the water inside. The cold water tank 31 can supply water to the hot water tank 11, i.e., the cold water tank 31, the hot water tank 11, and the warm water tank 21 are connected in sequence. The third inlet is used to replenish the cold water tank 31 with room temperature water.

[0052] The cold water tank assembly 30 also includes a second connecting water pipe 33. One end of the second connecting water pipe 33 is connected to the first water inlet 111 of the hot water tank 11, and the other end of the second connecting water pipe 33 is connected to the third water outlet 311 of the cold water tank 31, so that the third water outlet 311 supplies water to the hot water tank 11.

[0053] The second cooling assembly 32 can employ an existing compressor refrigeration system or a semiconductor refrigeration chip. Exemplarily, the second cooling assembly 32 is a compressor refrigeration system, which includes an evaporator disposed around the outer periphery of the cold water tank 31. The principle of the compressor refrigeration system is as follows: the compressor compresses the refrigerant into high-temperature, high-pressure vapor, which is then condensed and released heat in the condenser, and then passes through a capillary tube to form a low-temperature, low-pressure gas-liquid mixture. This mixture is then evaporated by the evaporator, absorbing heat to form low-temperature, low-pressure refrigerant vapor. Therefore, the evaporator absorbs heat, causing the cold water tank 31 to cool down, forming cold water.

[0054] For example, the outer peripheral surface of the cold water tank 31 is recessed with a groove, and the evaporator is embedded in the groove, which increases the contact area between the evaporator and the cold water tank 31 and improves the cooling effect.

[0055] The cold water tank 31 also has a room temperature water outlet 312 and a cold water outlet 313. The room temperature water outlet 312 is located on the upper part of the side wall of the cold water tank 31 and is used to discharge room temperature water. The cold water outlet 313 is located at the bottom of the cold water tank 31 and is used to discharge cold water.

[0056] For example, a third water inlet is located at the top of the cold water tank 31 to supply room temperature water to the cold water tank 31. The water inside the cold water tank 31 is cooled by the second cooling assembly 32, and its temperature is lower than that of room temperature water. The cold tank assembly 30 also includes a water distribution plate 34, which is disposed inside the cold water tank 31. The water distribution plate 34 is an existing structure designed to slow down the mixing rate of room temperature water and cold water, thereby reducing the rate of temperature rise of the cold water caused by the mixing with room temperature water.

[0057] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
