In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0040] like Figure 3 and Figure 4As shown, a plurality of flow channel units 148 are arranged at intervals inside the heat exchange plate 140. The plurality of flow channel units 148 are connected end to end in sequence to form a flow channel 141 for flowing pure water. A connecting portion 142 connected to the flow channel unit 148 is formed between two adjacent flow channel units 148. The connecting portion 142 is suitable for increasing the heat exchange area of ​​the flow channel unit 148.

[0041] According to the heat exchange plate 140 of the embodiment of the utility model, a plurality of flow channel units 148 are arranged at intervals inside the heat exchange plate 140, and a connecting portion 142 connected to the flow channel unit 148 is formed between two adjacent flow channel units 148. The connecting portion 142 serves as a fin of the flow channel unit 148, thereby increasing the heat exchange area of ​​the flow channel unit 148, increasing the heat exchange coefficient of the flow channel 141, and improving the heat exchange performance of the heat exchange plate 140.

[0042] It is understandable that if Figure 3 and Figure 4 As shown, a plurality of connection parts 142 are arranged at intervals along the length direction of the heat exchange plate 140 . The connection parts 142 are arranged at intervals so as to be in full contact with the heat exchange medium, thereby enhancing the heat exchange effect.

[0043] It is understandable that if Figure 3 and Figure 4 As shown, the connection part 142 extends along the width direction of the heat exchange plate 140, that is, the connection part 142 extends in the horizontal direction, and the distance between two adjacent connection parts 142 is equal. The distance between the two connection parts 142 is the width of the flow channel unit 148, and the width of the connection part 142 is specifically determined according to the width of the flow channel unit 148. Of course, the distance between adjacent connection parts 142 may also be unequal, for example, the distance between adjacent connection parts 142 located at the upper part is larger, and the distance between adjacent connection parts 142 located at the lower part is smaller. The width of the connection part 142 is 1-10 mm, and the specific width of the connection part 142 is determined according to the width of the flow channel unit 148.

[0044] It is understandable that if Figure 3 and Figure 4 As shown, the widths of two adjacent connection parts 142 are equal. Of course, the widths of two adjacent connection parts 142 may also be unequal, for example, the width of the connection part 142 located at the upper part is smaller, and the width of the connection part 142 located at the lower part is larger.

[0045] It is understandable that if Figure 3 and Figure 4 As shown, the side wall of the flow channel unit 148 is provided with a transition slope, and the transition slope is connected to the connecting portion 142 .

[0046] It is understandable that at least one connection portion 142 extends to the edge of the heat exchange plate 140. Extending the connection portion 142 to the edge of the heat exchange plate 140 allows the edge of the heat exchange plate 140 to also serve as a part of the heat exchange fins of the flow channel 141, further enhancing the heat exchange performance of the heat exchange plate 140. Specifically, Figure 3 and Figure 4 As shown, the upper connection portion 142 extends to the left side of the heat exchange plate 140 , and the lower connection portion 142 extends to the right side of the heat exchange plate 140 .

[0047] like Figure 6 and Figure 7 As shown, the heat exchange plate 140 is provided with a clean water outlet 123 and a clean water inlet 122, and a flow channel 141 for pure water to flow is provided inside the heat exchange plate 140, one end of the flow channel 141 is connected to the clean water inlet 122, and the other end of the flow channel 141 is connected to the clean water outlet 123; the inner wall of the flow channel 141 is provided with a protrusion 145, and the protrusion 145 is suitable for increasing the heat exchange area between the inner wall of the flow channel 141 and the pure water.

[0048] According to the heat exchange plate 140 of the embodiment of the utility model, by setting a protrusion 145 on the inner wall of the flow channel 141, the protrusion 145 increases the heat exchange area between the inner wall of the flow channel 141 and the pure water, increases the heat exchange coefficient of the flow channel, and improves the heat exchange performance of the heat exchange plate 140.

[0049] It can be understood that the protrusion 145 protrudes inward relative to the inner wall of the flow channel 141, and the protrusion 145 is integrally formed with the inner wall of the flow channel 141. Specifically, the protrusion 145 is formed by punching the inside of the flow channel 141 inward. According to the heat exchange plate 140 of the embodiment of the utility model, by providing the protrusion 145 on the inner wall of the flow channel 141, the protrusion 145 increases the heat exchange area between the inner wall of the flow channel 141 and the pure water, increases the heat exchange coefficient of the flow channel 141, and improves the heat exchange performance of the heat exchange plate 140.

[0050] It should be noted here that the protrusion 145 is provided on the inner wall of the flow channel 141 . The protrusion 145 may be provided on each flow channel unit 148 , or may be provided on only some of the flow channel units 148 .

[0051] It is understandable that if Figure 3 and Figure 4 As shown, the inner wall of the flow channel 141 is provided with a plurality of protrusions 145, and the plurality of protrusions 145 are arranged at intervals. The plurality of protrusions 145 are arranged at intervals so that the heat storage medium in each area can fully exchange heat with the pure water in the flow channel 141, thereby further improving the heat exchange efficiency of the heat exchange plate 140.

[0052] It can be understood that the plurality of protrusions 145 are arranged in at least one row along the length direction of the flow channel 141 , and the distance between two adjacent protrusions 145 in each row is equal.

[0053] It should be noted here that the distance between two adjacent protrusions 145 is specifically determined according to the length of the flow channel unit 148 and the size of the protrusion 145. Of course, the distance between two adjacent protrusions 145 may also be unequal, for example, more protrusions 145 are set in the lower flow channel unit 148, and fewer protrusions 145 are set in the upper flow channel unit 148.

[0054] It is understandable that the cross-sectional width of the protrusion 145 gradually increases or first increases and then decreases along the flow direction of the pure water, which can reduce the resistance of the protrusion 145 to the pure water and reduce the output pressure requirement of the pump body.

[0055] like Figure 3 As shown, in one embodiment, the protrusion 145 is hemispherical, and the cross-sectional width of the protrusion 145 first increases and then decreases along the flow direction of the pure water. A plurality of protrusions 145 are arranged in a plurality of rows along the length direction of the flow channel 141, and a plurality of protrusions 145 are arranged in each row. The distance between two adjacent protrusions 145 in the same row is equal.

[0056] like Figure 5 As shown, in one embodiment, the protrusion 145 is hemispherical, and the cross-sectional width of the protrusion first increases and then decreases along the flow direction of the pure water. A plurality of protrusions 145 are arranged in a row along the length direction of the flow channel 141, and a plurality of protrusions 145 are arranged in each row. The distance between two adjacent protrusions 145 in the same row is equal.

[0057] In another embodiment, Figure 4 As shown, the protrusion 145 is V-shaped, with the end of the V-shaped protrusion with a smaller width facing the direction of pure water approaching, and the end of the V-shaped protrusion with a larger width facing the direction of pure water moving away. The setting can reduce the resistance of the V-shaped protrusion to the pure water.

[0058] It is understandable that if Figure 6 and Figure 7 As shown, the heat exchange plate 140 is provided with a first guide channel 146 and a second guide channel 147 inside. The clean water inlet 122 is connected to one end of the flow channel 141 through the first guide channel 146. The first guide channel 146 is suitable for guiding the pure water input into the clean water inlet 122 into the flow channel 141. The clean water outlet 123 is connected to the other end of the flow channel 141 through the second guide channel 147. The second guide channel 147 is suitable for guiding the pure water after the heat exchange in the flow channel 141 into the clean water outlet 123.

[0059] It should be noted here that the first guide channel 146 and the second guide channel 147 are grooves formed by stamping, and the first guide channel 146, the second guide channel 147 and the flow channel unit 148 are stamped in the same manner.

[0060] It is understandable that if Figure 6 and Figure 7 As shown, the cross-sectional area of ​​the first flow guide channel 146 gradually increases along the flow direction of the pure water, that is, the cross-sectional area of ​​the first flow guide channel 146 gradually increases from left to right, and the cross-sectional area of ​​the right end of the first flow guide channel 146 is the largest and is the same as the cross-sectional area of ​​the flow channel unit 148. After the pure water enters the first flow guide channel 146 through the clean water inlet 122, the cross-sectional area of ​​the first flow guide channel 146 gradually increases from left to right, which effectively reduces the resistance of the pure water. The cross-sectional area of ​​the second flow guide channel 147 gradually decreases along the flow direction of the pure water, that is, the cross-sectional area of ​​the second flow guide channel 147 gradually decreases from right to left. After the heat exchange of the pure water in the flow channel 141 is completed, the pure water enters the second guide channel 147, and enters the clean water outlet 123 under the guiding effect of the second guide channel 147. Since the cross-sectional area of ​​the second guide channel 147 gradually decreases along the flow direction of the pure water, the second guide channel 147 can gather and guide the pure water, thereby reducing the resistance of the pure water when it flows out.

[0061] like Figure 3 and Figure 4 As shown, a plurality of flow channel units 148 are arranged at intervals inside the heat exchange plate 140, and the plurality of flow channel units 148 are connected end to end in sequence to form a flow channel 141 for pure water to flow, one end of the flow channel 141 is connected to the clean water inlet 122, and the other end of the flow channel 141 is connected to the clean water outlet 123.

[0062] According to the heat storage device of the embodiment of the utility model, a plurality of flow channel units 148 arranged at intervals are arranged inside the heat exchange plate 140, and the plurality of flow channel units 148 are connected end to end in sequence to form a flow channel 141 for pure water to flow. Since the distance between the flow channel units 148 is not affected by the bending radius, the distance between two adjacent flow channel units 148 can be set very small, which effectively reduces the volume of the heat storage device. In addition, as the distance between two adjacent flow channel units 148 decreases, more flow channel units 148 can be arranged within a unit area, thereby improving the heat exchange efficiency of the heat storage device.

[0063] It should be noted here that Figure 3 As shown, in two adjacent flow channel units 148, the head end of one flow channel unit 148 is located on one side of the heat exchange plate 140, and the head end of the other flow channel unit 148 is located on the other side of the heat exchange plate 140, as shown in FIG. Figure 3As shown, from the bottom to the top, the head end of the first flow channel unit 148 is located on the left side of the heat exchange plate 140, and the tail end is located on the right side of the heat exchange plate 140; the head end of the second flow channel unit 148 is located on the right side of the heat exchange plate 140, and the tail end is located on the left side of the heat exchange plate 140. When connecting, it is only necessary to connect the tail end of the first flow channel unit 148 with the head end of the second flow channel unit 148. Similarly, the connection method of other flow channel units 148 is the same as the above method, which will not be described in detail here.

[0064] It is understandable that if Figure 1 As shown, the shell 110 includes a shell body 111 and an end cover 112. The shell body 111 is a rectangular parallelepiped. An opening is provided on one side of the shell 110. The end cover 112 is provided in the opening and connected to the shell body 111. The end cover 112 cooperates with the shell body 111 to form a heat storage chamber 1111.

[0065] It is understandable that if Figure 1 As shown, the heat exchange plate 140 is a rectangular plate. Of course, the shape of the heat exchange plate 140 is not limited thereto, and may also be circular, trapezoidal or other shapes. The specific shape of the heat exchange plate 140 is determined according to the shape of the shell 110 .

[0066] It should be noted that the heat exchange plate 140 in this embodiment is a flat plate structure. Of course, the heat exchange plate 140 can also be an arc-shaped plate structure, which is specifically determined according to the shape of the shell 110. The sizes of the heat exchange plates 140 can be equal or unequal. Preferably, the shapes and sizes of the heat exchange plates 140 are equal, so that different heat exchange plates 140 can be interchangeable during the assembly process, which is convenient for mass production and reduces production costs.

[0067] It is understandable that if Figure 2 As shown, the heat storage device includes a plurality of heat exchange plates 140. In this embodiment, the number of the heat exchange plates 140 is three. Of course, the number of the heat exchange plates 140 is not limited thereto, and the number of the heat exchange plates 140 is specifically determined according to the size of the shell 110. When the shell 110 is vertically arranged, the heat exchange plates 140 are arranged in the heat storage cavity 1111 along the height direction of the shell. The heat exchange plates 140 may be parallel to the side wall of the shell 110, or the heat exchange plates 140 may form an acute angle with the side wall of the shell 110; preferably, the heat exchange plates 140 are arranged parallel to the side wall of the shell 110.

[0068] The plurality of heat exchange plates 140 are arranged at intervals along the thickness direction of the shell 110. The plurality of heat exchange plates 140 are arranged at intervals, which can increase the heat exchange area between the heat exchange plates 140 and the heat storage medium, and improve the heat exchange efficiency of the heat exchange plates 140. The larger the distance between two adjacent heat exchange plates 140, the more heat storage medium can be used for heat exchange between the two heat exchange plates 140, and the larger the volume of the heat storage device; the smaller the distance between two adjacent heat exchange plates 140, the less heat storage medium between the two heat exchange plates 140, and the smaller the volume of the heat storage device. Therefore, the distance between two adjacent heat exchange plates 140 needs to be determined by comprehensively considering the amount of the heat storage medium and the volume of the shell 110.

[0069] Furthermore, the heat exchange plate 140 close to the side wall of the shell 110 is spaced a certain distance from the side wall of the shell 110, so that a certain amount of heat storage medium is filled between the heat exchange plate 140 close to the side wall of the shell 110 and the side wall of the shell 110. The heat storage medium between the side wall of the shell 110 and the heat exchange plate 140 can be used to fully heat the pure water in the flow channel, thereby further improving the heat exchange efficiency of the heat exchange plate 140.

[0070] It should be noted that the thickness direction of the housing 110 is Figure 1 In the direction indicated by the arrow X, the width direction of the housing 110 is Figure 1 In the direction indicated by the arrow Y, the height direction of the housing 110 is Figure 1 The direction indicated by the arrow Z.

[0071] It is understandable that if Figure 2 As shown, the distance between two adjacent heat exchange plates 140 is equal, which can ensure that the amount of heat storage medium between each heat exchange plate 140 is equal, and the heat received by each heat exchange plate 40 is roughly equal, ensuring that the water temperature output by the heat storage device is stable, thereby enhancing the user experience.

[0072] It is understandable that if Figures 3 to 5 As shown, the plurality of flow channel units 148 are arranged at intervals along the length direction of the heat exchange plate 140, that is, along Figure 3 Two adjacent flow channel units 148 are parallel to each other, so that more flow channels 141 can be arranged on the heat exchange plate 140 to further enhance the heat exchange efficiency of the heat exchange plate 140.

[0073] It is understandable that if Figures 3 to 5As shown, the flow channel unit 148 extends along the width direction of the heat exchange plate 140, that is, the flow channel unit 148 extends in the horizontal direction. Of course, the flow channel unit 148 can also form an acute angle with the horizontal plane, that is, the flow channel unit 148 is inclined. The distance between two adjacent flow channel units 148 is equal, which can ensure that the pure water in the flow channel unit 148 is evenly distributed on the heat exchange plate 140, so that the pure water and the heat storage medium can fully exchange heat, thereby improving the heat exchange efficiency.

[0074] It is understandable that if Figures 3 to 5 As shown, the widths of two adjacent flow channel units 148 are equal. Of course, the width of the flow channel unit 148 close to the heater 130 may be larger, and the width of the flow channel unit 148 far from the heater 130 may be smaller. In this embodiment, the distance between two adjacent flow channel units 148 is 1-10 mm.

[0075] It is understandable that if Figures 3 to 5 As shown, the clean water inlet 122 and the clean water outlet 123 are located on the same side of the heat exchange plate 140, and the clean water inlet 122 and the clean water outlet 123 extend to the outside of the shell 110, and the clean water inlet 122 is located below the clean water outlet 123. Specifically, a plurality of first through holes are provided at the upper portion of the end cover 112, and the positions of the first through holes correspond to the positions of the clean water outlet 123 one by one, and the clean water outlet 123 extends to the outside of the shell 110 through the first through holes, and the edges of the first through holes are sealed with the clean water outlet 123. Similarly, a plurality of second through holes are provided at the lower portion of the end cover 112, and the positions of the second through holes correspond to the positions of the clean water inlet 122 one by one, and the clean water inlet 122 extends to the outside of the shell 110 through the second through holes, and the edges of the second through holes are sealed with the clean water inlet 122. The clean water inlet 122 and the clean water outlet 123 are arranged on the same side of the heat exchange plate 140 , so that the clean water inlet 122 and the clean water outlet 123 can be conveniently connected to the pipeline system, thereby improving assembly efficiency.

[0076] It is understandable that if Figure 2 As shown, the heat storage device further includes a heater 130, which is disposed in the heat storage chamber 1111 and is used to heat the heat storage medium. The heater 130 is an electric heater 130, and of course, it can also be other types of heaters 130.

[0077] It is understandable that if Figure 2 As shown, the heater 130 is located below the heat exchange plate 140. Since the heat generated by the heater 130 moves upward, the heater 130 is arranged below the heat exchange plate 140. The heat generated by the heater 130 moves upward and is fully exchanged with the heat exchange plate 140, thereby effectively improving the heat exchange efficiency of the heat exchange plate 140.

[0078] It is understandable that if Figure 1 As shown, the upper part of the housing 110 is provided with an air outlet 114 in communication with the heat storage chamber 1111. The air outlet 114 is used to discharge the gas in the heat storage chamber 1111 to prevent the internal pressure of the housing 110 from being too high, which may lead to a dangerous situation. Preferably, the air outlet 114 is located at the top of the housing 110. Since the air in the heat storage chamber 1111 is often located at the top of the housing 110, the air outlet 114 is arranged at the top of the housing 110 to allow more air to be discharged.

[0079] It is understandable that if Figure 8 As shown, the heat exchange plate 140 includes a first plate body 143 and a second plate body 144. The first plate body 143 and the second plate body 144 are both made of metal. The plate body of the metal material has good ductility and can be conveniently stamped. The second plate body 144 is arranged on one side of the first plate body 143. A flow channel 141 for pure water to flow is formed between the first plate body 143 and the second plate body 144. The side edge of the first plate body 143 is stamped and connected with the corresponding side edge of the second plate body 144, so that the first plate body 143 and the second plate body 144 are sealed and matched.

[0080] It should be noted here that there are many ways to stamp and connect the side of the first plate body 143 with the corresponding side of the second plate body 144, for example: the side of the first plate body 143 is aligned with the side of the second plate body 144, and the side of the first plate body 143 and the side of the second plate body 144 are directly stamped so that the side of the first plate body 143 and the side of the second plate body 144 are connected together; or, the side of the first plate body 143 and the side of the second plate body 144 are bent to the same side, and the side of the first plate body 143 and the side of the second plate body 144 are connected together by stamping the bent part; or, one of the side of the first plate body 143 and the side of the second plate body 144 has a protruding convex edge relative to the other, and the convex edge is bent to one side of the other and then stamped, and the side of the first plate body 143 and the side of the second plate body 144 can also be stamped together.

[0081] According to the heat exchange plate 140 of the embodiment of the utility model, by bending the side edge of the first plate body 143 and the corresponding side edge of the second plate body 144 to the same side and punching them together, a sealed fit between the first plate body 143 and the second plate body 144 is achieved without changing the properties of the metal, avoiding rust at the connection between the first plate body 143 and the second plate body 144, and not affecting the quality of pure water.

[0082] It can be understood that the first plate body 143 and the second plate body 144 are equal in shape and size, and the first plate body 143 and the second plate body 144 are symmetrically arranged, which can facilitate mass production and effectively reduce production costs.

[0083] It is understandable that the heat exchange plate 140 further includes a sealing ring (not shown), which is made of a flexible material such as rubber or silicone. The sealing ring is disposed at the edge of the first plate body 143 facing the second plate body 144 or the edge of the second plate body 144 facing the first plate body 143. After the side edge of the first plate body 143 and the side edge of the second plate body 144 are connected by stamping, the first plate body 143 and the second plate body 144 squeeze the sealing ring, thereby achieving a sealing fit between the sealing ring and the first plate body 143 and the second plate body 144.

[0084] It is understandable that if Figure 8 As shown, the flow channel unit 148 is formed on the side of the first plate 143 facing the second plate 144 and the side of the second plate 144 facing the first plate 143. In this case, the flow channel unit 148 includes a groove provided on the side of the first plate 143 facing the second plate 144 and a groove provided on the side of the second plate 144 facing the first plate 143. The position of the groove of the first plate 143 corresponds to the position of the groove of the first plate 143. The groove of the first plate 143 and the groove of the first plate 143 are buckled together to form the flow channel unit 148. The flow channel unit 148 can also be formed on the side of the first plate 143 facing the second plate 144. In this case, the flow channel unit 148 includes a groove provided on the side of the first plate 143 facing the second plate 144, and the side of the second plate 144 facing the first plate 143 is not provided with a groove; the flow channel unit 148 can be formed on the side of the second plate 144 facing the first plate 143. At this time, the flow channel unit 148 includes a groove disposed on a side of the second plate body 144 facing the first plate body 143 , and no groove is disposed on a side of the first plate body 143 facing the second plate body 144 .

[0085] It is understandable that if Figure 3 and Figure 4 As shown, there is a connecting portion 142 between two adjacent flow channel units 148 , and the connecting portion 142 extends along the width direction of the heat exchange plate 140 . The connecting portion 142 of the first plate body 143 is sealed with the connecting portion 142 of the second plate body 144 to separate the two adjacent flow channel units 148 .

[0086] It is understandable that a sealing strip is provided between the connection portion 142 of the first plate 143 and the connection portion 142 of the second plate 144, and the sealing strip is sealed with the connection portion 142 of the first plate 143 and the connection portion 142 of the second plate 144. The material of the sealing strip is the same as that of the sealing ring, and further, the sealing strip and the sealing ring are integrally formed.

[0087] By stamping the edge of the first plate body 143 and the edge of the second plate body 144, the connection part 142 of the first plate body 143 and the connection part 142 of the second plate body 144 can be fitted, thereby achieving a sealed fit between the connection part 142 of the first plate body 143 and the connection part 142 of the second plate body 144. However, when the connection part 142 of the first plate body 143 and the connection part 142 of the second plate body 144 are not flat, there is a gap between the connection part 142 of the first plate body 143 and the connection part 142 of the second plate body 144 after stamping, which easily leads to sealing failure. By providing a sealing strip between the connection part 142 of the first plate body 143 and the connection part 142 of the second plate body 144, the sealing strip is used to seal with the connection part 142 of the first plate body 143 and the connection part 142 of the second plate body 144, thereby effectively improving the sealing performance of the heat exchange plate 140.

[0088] It can be understood that the outer surface of the connection part 142 is provided with a plurality of protrusions (not shown), the plurality of protrusions are arranged at intervals, and the protrusions are suitable for increasing the heat exchange area between the connection part 142 and the heat storage medium.

[0089] It can be understood that a plurality of convex portions (not shown) are arranged at intervals on the side of the connection portion 142 of the first plate body 143 away from the second plate body 144, and the plurality of convex portions are arranged at equal intervals, and the convex portions protrude relative to the surface of the heat exchange plate 140, thereby increasing the heat exchange area between the connection portion 142 and the heat storage medium, transferring more heat to the pure water in the flow channel unit 148, and enhancing the heat exchange effect. Of course, a plurality of convex portions can also be arranged at intervals on the side of the connection portion 142 of the second plate body 144 away from the first plate body 143. The convex portions are formed by stamping the connection portion 142 of the first plate body 143 and the second plate body 144, and the convex portions are hemispherical, drag spherical or regular polygonal, and preferably, the convex portions are hemispherical.

[0090] It is understandable that the side of the first plate body 143 facing away from the second plate body 144 and / or the side of the second plate body 144 facing away from the first plate body 143 is coated with an anti-corrosion coating. Since the first plate body 143 and the second plate body 144 are in the heat storage medium for a long time, when the heat storage medium is water, the heat exchange plate 140 is prone to rust. By coating the anti-corrosion coating on the side of the first plate body 143 facing away from the second plate body 144 and / or the side of the second plate body 144 facing away from the first plate body 143, the heat exchange plate 140 can be prevented from rusting, which effectively extends the service life of the heat exchange plate 140 and enhances the product competitiveness.

[0091] Furthermore, the first plate 143 and the second plate 144 are both made of stainless steel, and the stainless steel heat exchange plate 140 can effectively prevent rust. Preferably, the first plate 143 and the second plate 144 are both made of food-grade stainless steel to improve the safety of the drinking water equipment.

[0092] like Figures 1 to 5 As shown, the heat storage device according to the second embodiment of the utility model includes a shell 110 and the heat exchange plate 140 described in any of the above embodiments, the shell 110 has a heat storage cavity 1111 inside, the heat storage cavity 1111 is filled with a heat storage medium, and the heat exchange plate 140 is arranged in the heat storage cavity 1111.

[0093] It is understandable that a heat storage medium supply port 113 is also provided on the top of the shell 110, and the heat storage medium supply port 113 is used to supply the heat storage medium to the heat storage chamber 1111. 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. Preferably, the heat storage medium supply port 113 is provided on the shell body.

[0094] The housing 110 is provided with a liquid level detection component (not shown), which is used to detect the liquid level of the heat storage medium in the heat storage chamber 1111, so as to determine the replenishment amount of the heat storage medium. The liquid level detection component can be a structure such as a water level probe.

[0095] Furthermore, a temperature measuring component 116 is disposed in the housing 110 , and the temperature measuring component 116 is suitable for detecting the temperature of the heat storage medium. Preferably, the heat storage medium is disposed on the end cover 112 .

[0096] It should be noted that the embodiment of the utility model takes water as the heat storage medium for illustration. 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 may not be provided on the top of the shell 110.

[0097] The drinking water equipment according to the third embodiment of the utility model comprises a heating device and any one of the above heat exchange plates, wherein the water inlet of the heating device is connected to the flow channel.
