[0034] See also Figure 1-Figure 4 An embodiment of the utility model provides a heat storage device 100 including: a shell 110 and a heat exchange component 120 .

[0035] A heat storage chamber 111 is provided in the housing 110, and a heat exchange component 120 is provided in the heat storage chamber 111. A heat storage medium is filled between the heat exchange component 120 and the inner wall of the heat storage chamber 111. The heat storage medium may be a phase change material of water, paraffin or inorganic salts. Since the enthalpy change of the phase change material during phase change is higher than the enthalpy change during temperature change, for example, the heat released when water condenses into ice at 0°C is roughly equal to the heat released when water is heated from 0°C to 80°C, the phase change material has a high energy density and a small volume. The phase change material is used for heat storage, and the heat storage effect is better, and the structure volume of the heat storage device 100 is small.

[0036] For further information, see Figure 1 , the heat exchange assembly 120 includes at least one heat exchange tube 121, and the heat exchange tube 121 is bent along the thickness direction of the shell 110 to form multiple sections to form a heat exchange flow channel that is bent and connected. It should be noted that the arrangement design of the heat exchange tube in the traditional technology is relatively unreasonable, and the space of the heat storage chamber 111 cannot be fully utilized, resulting in the problem of low heat exchange efficiency. In the technical solution provided by the utility model, the heat exchange tube 121 is bent along the thickness direction of the shell 110, so that the heat exchange tube 121 has a curved and connected heat exchange flow channel, which can fully utilize the space of the heat storage chamber 111 and make the arrangement of the heat exchange tube 121 more compact. In this way, under the same volume of the heat storage chamber 111, more lengths of heat exchange tubes 121 can be set to increase the heat exchange area, thereby significantly improving the heat exchange efficiency of the heat exchange assembly 120. Specifically, the heat exchange tube 121 is provided with a clean water inlet 122 and a clean water outlet 123, and the clean water inlet 122 and the clean water outlet 123 are connected to the heat exchange flow channel. Taking the application of the heat storage device 100 to drinking water equipment as an example, when the purified water flows in the heat exchange flow channel, it can absorb heat from the heat storage medium to increase the temperature, which is convenient for the subsequent instant heating of the heating component. Due to the improved heat exchange efficiency, the purified water has a higher temperature when entering the heating component for heating, and the heating component does not need to use a large power to heat the purified water, which can effectively reduce energy consumption. It should be noted that, please refer to Figure 1 In the figure, the X-axis direction is the length direction of the shell 110, the Y-axis direction is the thickness direction of the shell 110, and the Z-axis direction is the height direction of the shell 110.

[0037] In an alternative embodiment, see Figure 2 , the heat exchange tube 121 includes at least two heat exchange branch tubes 1211 arranged in sequence along the thickness direction of the shell 110, and two adjacent heat exchange branch tubes 1211 are connected end to end through the first reversing elbow 1212. Specifically, in an optional embodiment, the heat exchange tube 121 is bent once to form two heat exchange branch tubes 1211, that is, the heat exchange tube 121 is U-shaped when viewed from above; in another optional embodiment, the heat exchange tube 121 is bent twice to form three heat exchange branch tubes 1211, and the heat exchange tube 121 is N-shaped when viewed from above; in another optional embodiment, the heat exchange tube 121 is bent three times to form four heat exchange branch tubes 1211, and the heat exchange tube 121 is M-shaped when viewed from above. It should be noted that the heat exchange tube 121 is preferably bent in the same plane, so that each heat exchange branch tube 1211 is arranged in parallel, so that the utilization efficiency of the heat storage chamber 111 is also higher. In order to reduce the resistance to the flow of clean water, adjacent heat exchange branch pipes 1211 are connected at their ends through a first reversing elbow 1212, and the first reversing elbow 1212 extends along a horizontal plane. In other embodiments, straight pipes or other shapes of pipes may also be used for connection, and the utility model does not limit this.

[0038] It should also be noted that the heat exchange tube 121 can be integrally formed, and multiple bends are used to form the heat exchange branch tube 1211 and the first reversing bend 1212. In other optional embodiments, the heat exchange tube 121 can also include multiple sections of pipelines, which are connected in sequence according to the design to form a preset shape.

[0039] Furthermore, the heat exchange assembly 120 includes a plurality of heat exchange tubes 121, and each heat exchange tube 121 is stacked in sequence along the height direction of the shell 110. It can be understood that the heat exchange assembly 120 includes a plurality of heat exchange tubes 121 stacked along the height direction of the shell 110, which can improve the utilization efficiency of the space in the height direction of the shell 110, make the arrangement of the heat exchange tubes 121 more compact, and further improve the heat exchange efficiency. It should be noted that two adjacent heat exchange tubes 121 in the height direction of the shell 110 can be arranged in parallel or at a certain inclination angle, but in the case of parallel arrangement, the space loss between the two heat exchange tubes 121 is small, and more heat exchange tubes 121 can be arranged. Preferably, the spacing between each two adjacent heat exchange tubes 121 is equal, so that the distribution of the heat exchange tubes 121 is more uniform, and the heat exchange effect is also more uniform.

[0040] It should be noted that the heat exchange tubes 121 arranged in sequence in the height direction of the shell 110 can be arranged at intervals, and the heat exchange channels of each heat exchange tube 121 are not connected to each other, that is, each heat exchange tube 121 has a clean water inlet 122 and a clean water outlet 123, so that when the heat storage device 120 is applied to a water dispenser, the water output of the water dispenser can be increased. In another optional embodiment, two adjacent heat exchange tubes 121 in the height direction of the shell 110 are connected, so that the heat exchange channels of each heat exchange tube 121 are connected in sequence, that is, the heat exchange component 120 has a clean water inlet 122 and a clean water outlet 123. Such an arrangement can improve the heat exchange effect of the clean water in the heat exchange component 120, so that the clean water has a higher initial temperature. Specifically, two adjacent heat exchange branch pipes 1211 in the height direction of the shell 110 are connected end to end through a second reversing bend 1213, and the second reversing bend 1213 extends along the height direction of the shell 110. In other embodiments, straight pipes or other shapes of pipes can also be used for connection, and the utility model does not limit this.

[0041] As mentioned above, the heat exchange tube 121 can be formed in one piece and then bent according to the design requirements. In the technical solution provided by the present utility model, each heat exchange tube 121 can be formed separately and then connected. Each heat exchange tube 121 can also be formed in one piece and formed into a complete heat exchange assembly 120 by bending. Specifically, a heat exchange tube 121 with a sufficient length at one end can be used, so that it can be bent in sequence along the height direction of the shell 110 to form a plurality of branch tubes arranged in layers, and the entire heat exchange tube 121 can be further bent in sequence along the thickness direction of the shell 110 for multiple times to form a U-shaped, N-shaped or M-shaped pipeline, etc. In this embodiment, there is no need to go through multiple pipeline connections, and the manufacturing process of the heat exchange assembly 120 is simpler.

[0042] Furthermore, the heat storage device 100 further includes a heater 130 disposed in the heat storage chamber 111. It is understood that the heater 130 is disposed in the heat storage chamber 111, and the heater 130 is in contact with the heat storage medium to store heat for the heat storage medium. Figure 1 The heater 130 can be placed at the bottom of the heat exchange assembly 120 and set to the same shape as the heat exchange tube 121. For example, the heat exchange tube 121 is M-shaped when viewed from above, and the heater 130 is also set to be an M-shaped tube. In order to improve the heating efficiency, in another embodiment, the heater 130 includes multiple heating parts. Please refer to Figure 4 In one embodiment of the present invention, the heater 130 includes a first heating part 131 and a second heating part 132 connected to each other, the first heating part 131 and the second heating part 132 are arranged at an angle to each other, the first heating part 131 is located below the heat exchange component 120120, and the second heating part 132 is located on the side of the heat exchange component 120. That is, the angle between the first heating part 131 and the second heating part 132 can be 90°, 75°, 60°, 45°, 40°, 30°, etc., as long as the angle between the first heating part 131 and the second heating part 132 is not zero, that is, the first heating part 131 and the second heating part 132 are not parallel or collinear. Preferably, the angle between the first heating part 131 and the second heating part 132 is greater than or equal to 30°, and less than or equal to 90°.

[0043] In an optional embodiment, the angle between the first heating part 131 and the second heating part 132 is 90°. With this arrangement, not only can the heat storage medium below the heat exchange component 120 be heated, but also the heat storage medium on the side of the heat exchange component 120 can be heated along the height of the heat exchange component 120, resulting in a better heating effect, which is beneficial for the temperature of the heat storage medium to be uniform. In addition, since the first heating part 131 is arranged below the heat exchange component 120 and the second heating part 132 is arranged on the side of the heat exchange component 120 according to the internal space of the heat storage device 100, the space occupied by the heater 130 in the heat storage device 100 can be reduced while ensuring the heating effect, thereby reducing the volume of the heat storage device 100.

[0044] It should be noted that the heater 130 can be a heating wire or a constant temperature PTC, etc. The heater 130 is arranged in the heat storage chamber 111, and the two sides of the heater 130 are respectively in contact with the heat storage medium. When the heater 130 is turned on, it stores heat for the phase change material. After the phase change material is heated to a specified temperature, the phase change material is kept warm.

[0045] In the conventional technology, the heat storage device 100 of the instant hot water inlet machine has the problems of complex manufacturing process, high cost, and inconvenient installation and disassembly. Furthermore, an opening communicating with the heat storage chamber 111 is provided on one side of the shell 110, and a cover plate 112 is provided at the opening, and the cover plate 112 is detachably connected to the shell 110. By providing an opening on one side of the shell 110 and detachably connecting the cover plate 112 to the shell 110, on the one hand, the manufacturing process of the shell 110 can be simplified and the cost can be reduced, and on the other hand, the installation and maintenance of the heat storage device 100 can be facilitated.

[0046] There are many ways to connect the cover plate 112 to the shell 110. The cover plate 112 can be connected to the shell 110 by detachable connectors such as buckles, screws or bolts. In order to improve the convenience of disassembly of the cover plate 112, in an optional embodiment, please refer to 3, a boss 1121 is provided on one side of the cover plate 112, and the boss 1121 is used to be inserted into the heat storage chamber 111 to connect the cover body and the shell 110. Specifically, when the cover plate 112 is set at the opening, the boss 1121 extends into the heat storage chamber 111 and abuts against the inner wall surface of the heat storage chamber 111. It can be understood that the boss 1121 is equivalent to the longitudinal extension of the cover plate 112. When installing the cover plate 112, it is only necessary to align the boss 1121 with the edge of the opening and insert it so that one side of the boss 1121 abuts against the inner wall surface of the heat storage chamber 111; when removing the cover plate 112, it is only necessary to lightly push the edge of the cover plate 112 so that the boss 1121 is separated from the heat storage chamber 111, and installation and removal are simpler and faster.

[0047] It should be noted that there are many ways to set the boss 1121. In an optional embodiment, the boss 1121 is arranged in sections along the circumference of the cover plate 112. The boss 1121 can be arranged in a strip shape and arranged at intervals along the circumference of the cover plate 112. For example, one or more bosses 1121 are arranged on each side of the cover plate 112. The bosses 1121 arranged in sections make it easier to disassemble the cover plate 112. In another optional embodiment, the boss 1121 is arranged around the circumference of the cover plate 112. The shape of the boss 1121 matches the shape of the cover plate 112. If the cover plate 112 is arranged in a rectangular shape, the boss 1121 is square. If the cover plate 112 is arranged in a circular shape, the boss 1121 is annular. The boss 1121 arranged in an integrated manner can further improve the sealing of the cover plate 112 to the housing 110.

[0048] In order to further improve the sealing performance of the cover plate 112 to the housing 110, in an optional embodiment, a sealing member is provided on one side of the boss 1121. When the cover plate 112 is provided at the opening, the sealing member is located between the boss 1121 and the inner wall surface of the heat storage chamber 111. The sealing member can be made of elastic material or sealing colloid, etc., and is used to fill the gap between the boss 1121 and the housing 110 to prevent internal corrosion of the heat storage device 100. In an embodiment provided by the utility model, when the boss 1121 is integrally provided, the sealing member includes a rubber sealing ring. A mounting groove can be provided on one side of the boss 1121, and the rubber sealing ring can be interference-fitted with the mounting groove, or the rubber sealing ring can be directly sleeved on the outer periphery of the boss 1121. The rubber sealing ring can increase the friction between the boss 1121 and the inner wall of the shell 110, making the connection between the two more stable. The rubber sealing ring can also seal the gap between the boss 1121 and the inner wall of the shell 110 to ensure the sealing of the heat storage chamber 111, thereby increasing the service life of other installation structures in the heat storage chamber 111.

[0049] Furthermore, in order to improve the strength of the cover plate 112 and prevent the cover plate 112 from deforming, a reinforcing rib 1122 is provided on the cover plate 112. The reinforcing rib 1122 may be provided as one or more, and the plurality of reinforcing ribs 1122 are generally staggered and may be horizontally spaced or vertically spaced. In an optional embodiment, in order to improve the strength of the cover plate 112 in all directions, the reinforcing ribs 1122 are radially distributed, so that the overall strength of the cover plate 112 can be improved.

[0050] In the technical solution provided by the utility model, an opening is provided on one side of the housing 110, and a cover plate 112 is provided at the opening. The opening can be provided at the end or the side of the housing 110. In order to further simplify the manufacturing process of the housing 110, the housing 110 is a stamped integral part.

[0051] In some embodiments of the utility model, the side wall of the housing 110 is provided with a first opening 118 corresponding to the position of the clean water inlet 122, and the side wall of the housing 110 is provided with a second opening 119 corresponding to the position of the clean water outlet 123. The clean water inlet 122 is provided through the first opening 118 and extends out of the outside of the housing 110, and the clean water outlet 123 is provided through the second opening 119 and extends out of the housing 110. This arrangement enables the clean water inlet 122 and the clean water outlet 123 to be directly connected to the external water supply component, avoiding the clean water inlet 122 and the clean water outlet 123 from being indirectly connected to the external water supply component through the housing 110, which can simplify the installation process and improve the installation efficiency. It should be noted that the first opening 118 and the second opening 119 can be holes opened on the housing 110, or can be a tubular structure extending from the housing 110.

[0052] In addition, a heat storage medium supply port 113 and an air outlet 114 are also provided through the top of the shell 110. The heat storage medium supply port 113 is used to supply the heat storage medium to the heat storage chamber 111. The heat storage medium supply port 113 can be a hole opened on the shell 110, or a tubular structure provided on the shell 110. The air outlet 114 is used to discharge the gas from the heat storage chamber 111. Similarly, the air outlet 114 can be a hole opened on the shell 110, or a tubular structure provided on the shell 110. In addition, a liquid level detection component 115 is provided on the top of the shell 110. The liquid level detection component 115 is used to monitor the liquid level of the heat storage medium in the heat storage chamber 111, so as to determine the supply amount of the heat storage medium. The liquid level detection component 115 can be a structure such as a water level probe. It should be noted that the embodiment of the utility model is illustrated by taking water as the heat storage medium. When the heat storage medium is other phase change materials such as paraffin, the heat storage medium supply port 113, the air outlet 114 and the liquid level detection component 115 may not be provided on the top of the shell 110.

[0053] In addition, a temperature measuring component 116 and a temperature control protection component 117 are also provided on the shell 110. The temperature measuring component 116 is a thermocouple temperature measuring tube for detecting the temperature of the heat storage medium in the shell 110. The temperature control protection component 117 can be a thermostat, which can generate a conduction or disconnection action according to the temperature change of the temperature measuring component 116 to play a protective role.

[0054] Based on the above-mentioned heat storage device 100, the utility model also provides a drinking water device, which also includes a water source component, a heating component and any one of the above-mentioned heat storage devices 100, the water source component is connected to the water inlet end of the heat storage device 100, and the heating component is connected to the water outlet end of the heat storage device 100.

[0055] The water source assembly includes a water supply component and a water pump, the water supply component is connected to the heat storage device 100 through a pipeline, and the water pump is connected to the pipeline between the water supply component and the heat storage device 100, and is used to pump the incoming water in the water supply component to the heat storage device 100. The water supply component is directly supplied with water by a water treatment system such as a water purifier, which saves the space occupied by the water tank and makes the structure of the drinking water device more compact.

[0056] When the drinking water equipment is powered on, it first enters the heat storage mode, and the heater 130 is turned on to store heat for the heat storage medium, and the heat storage medium is heated to a specified temperature and then kept warm. When the working mode of the drinking water equipment is the heat storage mode, it means that the pre-stored heat in the heat storage medium has been completely or partially dissipated or used, and it is necessary to start the heater 130 to store heat for the heat storage medium. When the user takes water, the drinking water equipment enters the water outlet mode, and the water pump pumps the clean water of the water supply component to the heat storage device 100 to be preheated to a certain temperature, and then the preheated clean water enters the heating component to be heated to a specified temperature. Since the water has been preheated to a certain temperature before entering the heating pipe, the clean water can be instantly heated after passing through the heating component, meeting the use requirements of quick water extraction.

[0057] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not deviate from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
