Description

Technical Field

[0002] As an economical electrical appliance, water dispensers are generally popular among people. Currently, they are mainly used in places such as families, offices, and schools. Existing water dispensers usually can only provide drinking water at two temperatures: normal temperature cooked water and boiling water. Moreover, the boiling water provided is often directly supplied outward after being heated to boiling, with a high water temperature and cannot be directly drunk. Generally, it needs to be placed for a period of time to become cool boiled water before it can be drunk. There are also some water dispensers that can provide warm raw water or normal temperature raw water, such as pipeline machines. However, the normal temperature water provided by existing pipeline machines is directly filtered and unheated water flowing out through the water outlet for drinking, and the warm water provided is directly filtered and unheated water mixed with boiling water inside, or the filtered water is heated to a specified temperature (such as 45 °C, 50 °C, or 60 °C) and then flows out through the water outlet for drinking.

Specific embodiments

[0025] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model is given.

[0026] As Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides a fully-cooked water-cooled heat exchange system 100, which includes: a boiling water tank 110, a first cooling module 120, and a second cooling module 130. A first water inlet 112 and a first water outlet 114 are provided on the boiling water tank 110. The first water outlet 114 is connected to the first cooling module 120, and the first cooling module 120 is connected to the second cooling module 130. The fully-cooked water-cooled heat exchange system 100 further includes a boiling water outlet 116, a warm water outlet 127, and a normal temperature cooked water outlet 135. Among them, the first water inlet 112 is used to inject water into the boiling water tank 110. The boiling water outlet 116 is connected to the boiling water tank 110, the warm water outlet 127 is connected to the first cooling module 120, and the normal temperature cooked water outlet 135 is connected to the second cooling module 130.

[0027] Specifically, the boiling water in the boiling water tank 110 can be cooled into warm water under the action of the first cooling module 120. The first cooling module 120 is connected to the second cooling module 130, and the cooled warm water can be further cooled into normal temperature cooked water. When different temperatures of water are needed for drinking, just connect to the boiling water outlet 116 connected to the boiling water tank 110 to get boiling water, or connect to the warm water outlet 127 connected to the first cooling module 120 to get warm water, or connect to the normal temperature cooked water outlet 135 connected to the second cooling module 130 to get normal temperature cooked water. Among them, the first cooling module 120 and the second cooling module 130 can adopt a refrigerator or cool the boiling water in the form of a heat exchanger.

[0028] The fully-cooked water-cooled heat exchange system 100 provided by the embodiments of the present application can make the boiling water in the boiling water tank 110 flow into the first cooling module 120 through the first water outlet 114 provided on the boiling water tank 110, and the first water outlet 114 is connected to the first cooling module 120. In addition, the boiling water outlet 116 is connected to the boiling water tank 110, so that the boiling water in the boiling water tank 110 can be directly used. After the boiling water in the boiling water tank 110 flows into the first cooling module 120 through the first water outlet 114, it is cooled by the first cooling module 120 to form warm boiled water. Through the warm boiled water outlet 127 connected to the first cooling module 120, the warm boiled water formed by cooling by the first cooling module 120 can be directly used. After the warm boiled water at the first cooling module 120 flows into the second cooling module 130, it is cooled by the second cooling module 130 to form normal-temperature cooked water, and through the normal-temperature cooked water outlet 135 connected to the second cooling module 130, the normal-temperature cooked water formed by cooling by the second cooling module 130 can be directly used. In the above form, the water finally used by the user has been boiled and sterilized in the boiling water tank 110 to form fully-cooked water throughout the line, avoiding the user from drinking raw water that has not been boiled. Through the mutual cooperation of the first cooling module 120 and the second cooling module 130, while ensuring fully-cooked water in the full temperature range, more selectable temperatures can be achieved, so as to solve the problems in the prior art that the form of the water outlet is single, which is not conducive to meeting the use requirements of different people for cooked water at different temperatures, and is not conducive to ensuring drinking health.

[0029] As Figure 1 and Figure 3 shown, the first cooling module 120 includes a warm boiled water tank 121, a conduction pipe 126 connected to the warm boiled water tank 121, and a first water inlet pipe 123 connected to the first water inlet 112. The warm boiled water tank 121 is provided with a second water inlet 122 and a second water outlet 124. A first lead-out pipe 115 is connected to the first water outlet 114. The first lead-out pipe 115 is connected to the second water inlet 122 through the conduction pipe 126. A second lead-out pipe 125 is connected to the second water outlet 124. The second lead-out pipe 125 is connected to the second cooling module 130. Part of the first water inlet pipe 123 is sleeved on the conduction pipe 126. A first water inlet flow channel is formed between the first water inlet pipe 123 and the conduction pipe 126. The boiling water outlet 116 is located on the boiling water tank 110 or the first lead-out pipe 115. The warm boiled water outlet 127 is located on the warm boiled water tank 121 or the second lead-out pipe 125.

[0030] Specifically, the boiling water tank 110 is used to store boiling water at 90°C to 100°C, and the warm water tank 121 is used to store warm water at 40°C to 60°C. When in use, after the water in the boiling water tank 110 is heated to 100°C, 100°C boiling water can be directly taken from the boiling water outlet 116 for use (there may be a situation where the temperature is lower than 100°C after being placed for a while), warm water can also be taken from the warm water outlet 127 for use, and normal temperature cooked water (i.e., cooled boiled water) can be taken from the normal temperature cooked water outlet 135 for use.

[0031] Through the first outlet 114 provided on the boiling water tank 110 and the second inlet 122 provided on the warm water tank 121, after the first lead-out pipe 115 and the conduction pipe 126 that are connected communicate the first outlet 114 and the second inlet 122, the boiling water in the boiling water tank 110 can flow into the warm water tank 121. In addition, a boiling water outlet 116 is also provided on the boiling water tank 110 or the first lead-out pipe 115, so that the boiling water in the boiling water tank 110 can be directly used. The warm water tank 121 is used to store warm water, and the warm water is formed by the cooling of the boiling water in the boiling water tank 110 during the process of flowing into the warm water tank 121. A warm water outlet 127 is also provided on the warm water tank 121 or the second lead-out pipe 125, so that the warm water in the warm water tank 121 can be directly used.

[0032] As Figure 1 and Figure 4 shown, the second cooling module 130 includes a second inlet pipe 132 and an outlet pipe 134. The second inlet pipe 132 is sleeved on the outlet pipe 134. A second inlet water flow channel is formed between the second inlet pipe 132 and the outlet pipe 134, and the first inlet water flow channel and the second inlet water flow channel are connected. The normal temperature cooked water outlet 135 is located on the outlet pipe 134.

[0033] Specifically, by sleeving a part of the first water inlet pipe 123 on the conduction pipe 126, a first water inlet flow channel is formed between the first water inlet pipe 123 and the conduction pipe 126. When the potable pure water flows in the first water inlet pipe 123 and flows into the boiling water tank 110, the incoming pure water first flows into the second water inlet flow channel, then into the first water inlet flow channel, and finally flows into the boiling water tank 110. Among them, the first water inlet flow channel is formed between the inner wall of the first water inlet pipe 123 and the outer wall of the conduction pipe 126, and the second water inlet flow channel is formed between the inner wall of the second water inlet pipe 132 and the outer wall of the water outlet pipe 134. During the process of the pure water flowing into the boiling water tank 110 through the first water inlet pipe 123, and during the process of the boiling water in the boiling water tank 110 flowing into the warm water tank 121 through the conduction pipe 126, a heat exchange can be formed with the first water inlet pipe 123, so that the pure water in the first water inlet pipe 123 is heated, reducing the power consumption during heating, and at the same time, the boiling water can be cooled to meet the usage requirements of different cooked water temperatures. In actual applications, the pure water first flows into the second water inlet flow channel and exchanges heat with the warm water in the water outlet pipe 134. While heating the pure water, the warm water in the water outlet pipe 134 can be quickly cooled, so that the normal temperature cooked water (cooled boiled water) that can be directly drunk finally flows out of the water outlet pipe 134. After the heat exchange at the second water inlet flow channel, although the pure water rises to a certain temperature, the temperature difference from the boiling water is still far. At the first water inlet flow channel, it can continue to exchange heat with the boiling water in the conduction pipe 126, so that the water flowing into the warm water tank 121 from the conduction pipe 126 is reduced to about 45°C, and the temperature of the pure water flowing into the first water inlet pipe 123 is raised to about 80°C. Among them, the flowing direction of the pure water in the second water inlet flow channel is opposite to the flowing direction of the warm water in the water outlet pipe 134, and the flowing direction of the pure water in the first water inlet flow channel is opposite to the flowing direction of the boiling water in the conduction pipe 126, which is beneficial to improving the heat exchange efficiency and quickly cooling the temperature to the required temperature.

[0034] As Figure 2 shown, a first heating component 118 is arranged in the boiling water tank 110 for heating the water in the boiling water tank 110 to the boiling state; a second heating component 128 is arranged in the warm water tank 121 for keeping the water in the warm water tank 121 at the warm water state.

[0035] Specifically, the first heating component 118 in the boiling water tank 110 is used to boil the water in the boiling water tank 110, which is the basis for achieving fully heated water at all temperature ranges. The second heating component 128 in the warm water tank 121 mainly plays a role in keeping warm. After the boiled water in the boiling water tank 110 flows into the warm water tank 121, if the water in the warm water tank 121 is not used for a long time, it is necessary to keep the water warm to the required temperature through the second heating component 128. It can be understood that after the water in the boiling water tank 110 is heated to 100 °C, if it is not used in time, there will be heat dissipation. Therefore, the temperature of the boiling water in the boiling water tank 110 is generally set between 90 °C and 100 °C. Similarly, the temperature of the warm water in the warm water tank 121 generally remains between 40 °C and 60 °C. Among them, a first temperature sensor is provided in the boiling water tank 110, and a second temperature sensor is provided in the warm water tank 121 to better obtain the temperature of the water in the boiling water tank 110 and the warm water tank 121. In order to ensure that the water in the boiling water tank 110 and the warm water tank 121 meets the set temperature, heat insulation layers can be respectively provided on the outer sides of the boiling water tank 110 and the warm water tank 121 to prevent the heat in the boiling water tank 110 and the warm water tank 121 from dissipating too quickly, which is beneficial to ensuring the stability of the water temperature in the boiling water tank 110 and the warm water tank 121, and thus reducing the heating frequency.

[0036] Please refer to Figure 1 and Figure 2 , the first water inlet pipe 123 includes a first connecting pipe 1232 and a second connecting pipe 1234. The first connecting pipe 1232 is connected between the first water inlet 112 and the second connecting pipe 1234, and the second connecting pipe 1234 is sleeved on the conduction pipe 126; the second water inlet pipe 132 includes a third connecting pipe 1322 and a fourth connecting pipe 1324. The fourth connecting pipe 1324 is sleeved on the water outlet pipe 134, and a pure water inlet 1326 is also connected to the fourth connecting pipe 1324. The third connecting pipe 1322 is connected between the fourth connecting pipe 1324 and the second connecting pipe 1234.

[0037] Specifically, by setting the first water inlet pipe 123 in a segmented connection form, the assembly can be made simpler and more convenient, which is conducive to improving the assembly efficiency and reducing the maintenance cost. During use, by connecting the pure water inlet 1326 to the fourth connecting pipe 1324, pure water can flow into the fourth connecting pipe 1324 through the pure water inlet 1326. Since the fourth connecting pipe 1324 is sleeved on the water outlet pipe 134, the pure water finally flows into the first water inlet channel to perform heat exchange on the warm boiled water flowing out of the warm water tank 121. Then it flows into the second connecting pipe 1234 through the third connecting pipe 1322. Since the second connecting pipe 1234 is sleeved on the conduction pipe 126, the pure water finally flows into the second water inlet channel to perform heat exchange on the boiling water flowing out of the boiling water tank 110. The pure water that has undergone two heat exchanges finally flows into the boiling water tank 110 through the first connecting pipe 1232, and the temperature of the pure water that has undergone two heat exchanges can reach about 80 °C, which is conducive to reducing the electric energy required to heat the water to boiling.

[0038] As Figure 1 and Figure 2 shown, the conduction pipe 126 includes a first communication section 1262 and a second communication section 1264 connected in sequence. The first communication section 1326 is connected to the first lead-out pipe 115, the second communication section 1264 is connected to the second water inlet 122, and the second connecting pipe 1234 is sleeved on the first communication section 1262.

[0039] Specifically, when the boiling water in the boiling water tank 110 flows into the warm water tank 121 through the conduction pipe 126, it passes through the first lead-out pipe 115, the first communication section 1262, and the second communication section 1264 in sequence. Among them, since the second connecting pipe 1234 is sleeved on the first communication section 1262, the heat exchange mainly occurs in the first communication section 1262 to ensure the required heat exchange effect.

[0040] Please refer to Figure 1 , Figure 2 and Figure 3 , the opposite ends of the second connecting pipe 1234 are respectively connected with a first three-way pipe 140 and a second three-way pipe 150; the second connecting pipe 1234 and the first connecting pipe 1232 are respectively connected and communicated through two adjacent interfaces of the first three-way pipe 140, and one end of the first communication section 1262 passes through two of the interfaces of the first three-way pipe 140 and is connected and communicated with the first lead-out pipe 115; the third connecting pipe 1322 and the second connecting pipe 1234 are respectively connected and communicated through two adjacent interfaces of the second three-way pipe 150, and the other end of the first communication section 1262 passes through two of the interfaces of the second three-way pipe 150 and is connected and communicated with the second communication section 1264.

[0041] Specifically, by connecting the first three-way pipe 140 and the second three-way pipe 150 to both ends of the second connecting pipe 1234 respectively, when connecting, one end of the second connecting pipe 1234 is connected to the first connecting pipe 1232 through the first three-way pipe 140, and the other end of the second connecting pipe 1234 is connected to the third connecting pipe 1322 through the second three-way pipe 150. At the same time, one end of the first communication section 1262 passes through two of the interfaces of the first three-way pipe 140 to communicate with the first lead-out pipe 115. Please refer to Figure 5 , taking the connection at the first three-way pipe 140 as an example for detailed description. The first three-way pipe 140 is set as a T-shaped structure. To ensure the sealing performance of the connection, the second connecting pipe 1234 is connected to the first interface of the first three-way pipe 140, and the first connecting pipe 1232 is connected to the second interface of the first three-way pipe 140, and the above-mentioned first interface and second interface are at positions perpendicular to each other in the T-shaped structure. One end of the first communication section 1262 passes through the second connecting pipe 1234 and extends linearly to the third interface. The first interface and the third interface are located at both ends of the straight section of the T-shaped structure, and the third interface is hermetically connected to the second connecting pipe 1234 and is in communication with the first communication section 1262. The first lead-out pipe 115 is connected to the third interface to form a communication relationship with the first communication section 1262. The connection form at the second three-way pipe 150 is similar to that at the first three-way pipe 140, and will not be elaborated here.

[0042] Please continue to refer to Figure 1 and Figure 2 , the opposite ends of the fourth connecting pipe 1324 are respectively connected with a third three-way pipe 160 and a fourth three-way pipe 170; the fourth connecting pipe 1324 and the third connecting pipe 1322 are respectively communicated through two adjacent interfaces of the third three-way pipe 160, and one end of the water outlet pipe 134 passes through two of the interfaces of the third three-way pipe 160 to communicate with the second lead-out pipe 125; the fourth connecting pipe 1324 and the pure water inlet 1326 are respectively communicated through two adjacent interfaces of the fourth three-way pipe 170, and the other end of the water outlet pipe 134 passes through two of the interfaces of the fourth three-way pipe 170 to communicate with the normal temperature cooked water outlet 135.

[0043] Specifically, by connecting the third three-way pipe 160 and the fourth three-way pipe 170 to both ends of the fourth connecting pipe 1324 respectively, when connecting, one end of the fourth connecting pipe 1324 is connected to the third connecting pipe 1322 through the third three-way pipe 160. At the same time, one end of the water outlet pipe 134 passes through two of the interfaces of the third three-way pipe 160 to communicate with the second lead-out pipe 125. Similarly, the connection form at the fourth three-way pipe 170 is similar to that at the third three-way pipe 160, and will not be elaborated here. Adopting the above form is beneficial to simplifying the connection form, improving the convenience during connection, and reducing the operation difficulty.

[0044] In an alternative embodiment of the present application, the first connecting section 1262 and the water outlet pipe 134 are respectively in a meandering and coiled structure.

[0045] Specifically, in actual applications, the first connecting section 1262 and the water outlet pipe 134 can be connected in an S-shaped end-to-end manner or in a disk-winding form. By adopting the above forms, the heat transfer path of the first connecting section 1262 and the water outlet pipe 134 can be lengthened, the heat transfer effect can be improved, and the space occupied by the first connecting section 1262 and the water outlet pipe 134 can be reduced.

[0046] The present utility model also discloses a water dispenser, which includes the fully cooked water-cooled heat exchange system 100 in the foregoing embodiment. This water dispenser has the same structure and beneficial effects as the fully cooked water-cooled heat exchange system 100 in the foregoing embodiment. The structure and beneficial effects of the fully cooked water-cooled heat exchange system 100 have been described in detail in the foregoing embodiment and will not be elaborated herein.

Those skilled in the art can modify the technical solutions described in the above embodiments or perform equivalent replacements for some of the technical features; and all such modifications and replacements should fall within the protection scope of the appended claims of the present utility model.
