[0034] See below Figure 1-Figure 5 The drinking water equipment provided by the embodiment of the utility model is described.

[0035] See also Figure 1 The embodiment of the utility model provides a drinking water device, which includes a water supply component 200, a heat storage device 100 and a heating component 300. The water supply component 200 is connected to the water inlet end of the heat storage device 100, and is used to supply clean water to the heat storage device 100. The heat storage device 100 can preheat the clean water flowing through it to a certain temperature. The heating component 300 is connected to the water outlet end of the heat storage device 100, and is used to heat the clean water flowing through it to a required temperature and supply it to a water use component connected to the tail end of the heating component 300. The water use component can be a hot water faucet of an instant hot water dispenser.

[0036] Among them, the heat storage device 100 includes a shell 110, a heat exchange component 120 and a heater 130. A heat storage chamber 111 is provided in the shell 110. 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. 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. In the technical solution provided by the utility model, an opening is provided on one side of the shell 110, and a cover plate 112 is provided to seal the opening. On the one hand, the manufacturing process of the shell 110 can be simplified and the cost can be reduced. On the other hand, the installation and maintenance of the heat storage device 100 can also be facilitated. It should be noted that in order to facilitate observation, Figure 1 and Figure 2 The cover plate 112 is omitted. It should also be noted that, please refer to Figure 3 and Figure 5 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] The heat exchange component 120 is arranged in the heat storage chamber 111, and the 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 can be a phase change material of water, paraffin or inorganic salt. 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 degrees Celsius, the phase change material has high energy density and small volume. The phase change material is used to store heat, the heat storage effect is better, and the structure volume of the heat storage device 100 is small. The heat exchange component 120 includes a heat exchange flow channel, and a clean water inlet 123 and a clean water outlet 124 are provided on the heat exchange component 120, and the clean water inlet 123 and the clean water outlet 124 are connected to the heat exchange flow channel. When the clean 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 300.

[0038] The heater 130 is disposed in the heat storage chamber 111 and is used to store heat for the heat storage medium. It is understandable that the heater 130 is disposed in the heat storage chamber 111, and the heater 130 is in contact with the heat storage medium and is used to store heat for the heat storage medium. The heater 130 may include one or more heating parts, and the present invention does not limit this.

[0039] There are many ways to connect the cover plate 112 to the housing 110. The cover plate 112 can be connected to the housing 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 Figure 3 and Figure 4, 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 arranged 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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 an integral stamping part.

[0044] In order to improve the heating effect of the heater 130, in an optional embodiment, 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 120, and the second heating part 132 is located on the side of the heat exchange component 120. 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°.

[0045] 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 120, and the second heating part 132 is located on the side of the heat exchange component 120. It can not only heat the heat storage medium below the heat exchange component 120, but also heat the heat storage medium on the side of the heat exchange component 120 along the height of the heat exchange component 120, so the heating effect is better, which is conducive to achieving uniform temperature of the heat storage medium. 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. 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.

[0046] Further, according to an embodiment of the utility model, the heat exchange component 120 includes at least two heat exchange tubes 121 arranged in the heat storage chamber 111, each heat exchange tube 121 is provided with a heat exchange flow channel, and the clean water inlet 123 and the clean water outlet 124 are respectively connected to each heat exchange flow channel. By providing at least two heat exchange tubes 121, the flow area of ​​the heat exchange flow channel can be effectively increased, and the flow resistance of the clean water in the heat exchange flow channel can be reduced. Of course, in other embodiments, three groups of heat exchange flow channels, four groups of heat exchange flow channels, etc. can be arranged in parallel, and the number of heat exchange flow channels can be determined according to actual use requirements. With such a configuration, since the flow area of ​​the heat exchange flow channel in the heat exchange component 120 is increased, the flow resistance of the clean water in the heat exchange flow channel is reduced, and the water outlet flow rate of the instant hot water dispenser can be increased accordingly, shortening the water collection time of the user during use, and the user experience effect is better.

[0047] See also Figure 5 In another embodiment of the utility model, the heat exchange assembly 120 includes a heat exchange plate 122 disposed in the heat storage chamber 111, and at least one heat exchange channel is disposed on the heat exchange plate 122, and the clean water inlet 123 and the clean water outlet 124 are respectively connected to the heat exchange channel. The heat exchange plate 122 can be a double-layer structure, and the heat exchange channel can be stamped on the heat exchange plate 122. Compared with the heat exchange tube 121, the heat exchange plate 122 can further reduce the volume of the heat exchange assembly 120 on the basis of ensuring the heat exchange effect. It should be noted that a plurality of heat exchange channels can also be arranged on the heat exchange plate 122, so that each heat exchange channel is arranged in series or in parallel, and a plurality of heat exchange plates 122 can also be arranged in the heat storage chamber 111 at the same time, so that each heat exchange plate 122 is arranged in parallel and spaced apart.

[0048] In some embodiments of the present invention, please refer to Figure 3 The side wall of the shell 110 is provided with a first opening 118 corresponding to the position of the clean water inlet 123, and is also provided with a second opening 119 corresponding to the position of the clean water outlet 124. The clean water inlet 123 is penetrated through the first opening 118 and extends out of the outside of the shell 110, and the clean water outlet 124 is penetrated through the second opening 119 and extends out of the shell 110. This arrangement enables the clean water inlet 123 and the clean water outlet 124 to be directly connected to the external water supply component 200, avoiding the clean water inlet 123 and the clean water outlet 124 from being indirectly connected to the external water supply component 200 through the shell 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 shell 110, or can be a tubular structure extending from the shell 110.

[0049] 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.

[0050] 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.

[0051] It should be noted that the water supply assembly 200 includes a water supply component 210 and a water pump 220. The water supply component 210 is connected to the heat storage device 100 through a pipeline. The water pump 220 is connected to the pipeline between the water supply component 210 and the heat storage device 100, and is used to pump the purified water in the water supply component 210 to the heat storage device 100. Among them, the water supply component 210 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.

[0052] When the drinking water equipment is powered on, it first enters the heat storage mode, and the heater 130 in the heat storage device 100 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 220 sends the clean water pump 220 of the water supply component 210 to the heat storage device 100 to preheat to a certain temperature, and then the preheated clean water enters the heating component 300 to be heated to a specified temperature. Since the water has been preheated to a certain temperature before entering the heating component 300, the clean water can be instantly heated after passing through the heating component 300, meeting the use requirements of quick water extraction.

[0053] See also Figure 2In some embodiments of the present invention, the drinking water device further includes a reversing valve 400, which is arranged on the outlet pipe of the heating component 300, and a self-circulating pipe is connected to the pipe between the reversing valve 400 and the water inlet end of the water pump 220. The drinking water device can charge the heat storage medium by self-circulation, that is, the heating component 300 heats the water to a certain temperature and then inputs the water into the self-circulating pipe. The high-temperature water passes through the self-circulating pipe and transfers energy to the heat storage medium during the flow in the heat exchange component 120. After the water temperature drops, it flows into the heating component 300 for circulation heating. This arrangement can expand the use scenarios of the drinking water device. For example, when the water temperature required by the water component is high, the water pump 220 pumps the clean water of the water supply component 210 to the heat storage device 100, and the heater 130 in the heat storage device 100 is turned on to store heat for the heat storage medium, preheating the heat storage medium to a certain temperature, and then the preheated clean water enters the heating component 300 and is heated to a specified temperature. Since the water has been preheated to a certain temperature before entering the heating component 300, the clean water can be heated instantly after passing through the heating component 300, meeting the requirement of quick water extraction. When the water temperature required by the water-using component does not need to be too high, the drinking water equipment can charge the heat storage medium through self-circulation. It should be noted that when a reversing valve 400 and a self-circulating pipeline are provided, the heater 130 in the heat storage device 100 can be omitted, simplifying the structure of the system and reducing production costs.

[0054] See also Figure 1 and Figure 2 In some embodiments of the utility model, the drinking water equipment also includes a first temperature detection component 500 and a second temperature detection component 600; the first temperature detection component 500 is arranged at the water inlet end of the heating component 300, and is used to detect the water inlet end temperature T1 of the heating component 300, and the second temperature detection component 600 is arranged at the water outlet end of the heating component 300, and is used to detect the water outlet end temperature T2 of the heating component 300.

[0055] Since the heating component 300 is arranged in series at the water outlet end of the heat storage device 100, and the first temperature detection component 500 is arranged at the water inlet end of the heating component 300, it is equivalent to that the first temperature detection component 500 is arranged at the water outlet end of the heat storage device 100. The water temperature detected by the first temperature detection component 500 is both the water outlet temperature of the heat storage device 100 and the water inlet temperature T1 of the heating component 300. Therefore, when the clean water passes through the heat storage device 100, the heat storage device 100 preheats the clean water to a certain temperature T1.

[0056] When the heater 130 in the heat storage device 100 is working, the power P corresponding to the heater 130 is known, the power P is the rated power, the specific heat capacity C of water is constant, and the water inlet temperature T1 of the heating component 300 is detected by the first temperature detection component 500, and the water inlet temperature T1 of the heating component 300 is increased. The water output flow of the drinking water equipment will be increased, which can shorten the water collection time and improve the user experience.
