[0040] Figure 1 It is a structural schematic diagram of a first embodiment of a heat exchange plate provided in an embodiment of the utility model.

[0041] See also Figure 1 The utility model provides a heat exchange plate 140 , which is suitable for use in a heat storage device 100 . The heat exchange plate 140 has a flow channel body 141 inside. The heat exchange plate 140 is provided with a clean water inlet 122 and a clean water outlet 123 connected to the flow channel body 141 .

[0042] The flow channel body 141 includes a first flow channel unit 142 and a second flow channel unit 143 connected to each other. The first flow channel unit 142 has at least two first flow channels 1421 arranged in parallel, and the second flow channel unit 143 has a single second flow channel 1431. The clean water inlet 122 is connected to the first flow channel 1421 or the second flow channel 1431, and the clean water outlet 123 is connected to the first flow channel 1421 or the second flow channel 1431. The flow channel body 141 can be composed of multiple flow channels and a single flow channel mixed in series, and the positions of the multiple flow channels and the single flow channel can be determined according to actual use needs.

[0043] The flow channel body 141 may also only include a plurality of first flow channel units 142 connected to each other, the first flow channel unit 142 has at least two first flow channels 1421 arranged in parallel inside the structure, and the clean water inlet 122 and the clean water outlet 123 are both connected to the first flow channel 1421. This is equivalent to the flow channel body 141 being composed of multiple flow channels connected in series.

[0044] It should be noted that sheet metal stamping can be used to form two heat exchange bodies with flow channels, and then the two heat exchange bodies are sealed and connected to form a heat exchange plate 140. At this point, a closed flow channel is formed between the two relatively arranged heat exchange bodies, that is, the internal structure of the heat exchange plate 140 is provided with a flow channel body 141, and the heat exchange plate 140 is provided with a clean water inlet 122 and a clean water outlet 123 connected to the flow channel body 141, that is, one end of the flow channel body 141 is connected to the clean water inlet 122, and the other end of the flow channel body 141 is connected to the clean water outlet 123.

[0045] It can be understood that the heat exchange plate 140 provided in the embodiment of the utility model can construct a flow channel body 141 inside the heat exchange plate 140, and the flow channel body 141 can be configured according to the needs of use to include a first flow channel unit 142 and a second flow channel unit 143 connected to each other, the first flow channel unit 142 has an internal structure with at least two first flow channels 1421 arranged in parallel, and the second flow channel unit 143 has an internal structure with a single second flow channel 1431, which is equivalent to the flow channel body 141 being composed of a mixture of multiple flow channels and single flow channels in series; the flow channel body 141 can also be configured according to the needs of use to include a plurality of first flow channel units 142 connected to each other, and the first flow channel unit 142 has an internal structure with at least two first flow channels 1421 arranged in parallel, which is equivalent to the flow channel body 141 being composed of multiple flow channels in series.

[0046] Compared with a single flow channel with the same flow area provided in the heat exchange plate 140, the heat exchange plate 140 provided by the utility model can effectively increase the flow area of ​​the flow channel body 141 and reduce the flow resistance of the purified water in the flow channel body 141. When the heat exchange plate 140 is used in a drinking water device, since the flow area of ​​the flow channel body 141 in the heat exchange plate 140 is increased, the flow resistance of the purified water in the flow channel body 141 is reduced, and the water flow rate of the instant hot drinking water device can be increased accordingly, shortening the water collection time of the user during use, and providing a better user experience.

[0047] Continue reading Figure 1 In some embodiments of the present invention, when the flow channel body 141 includes a first flow channel unit 142 and a second flow channel unit 143 connected to each other, that is, the flow channel body 141 is composed of a mixture of multiple flow channels and a single flow channel in series.

[0048] Along the height direction of the heat exchange plate 140 , the first flow channel units 142 and the second flow channel units 143 are alternately arranged, the first flow channel units 142 and the second flow channel units 143 are connected end to end, and each first flow channel 1421 is connected to the second flow channel 1431 .

[0049] For example, a single second flow channel 1431 is connected to the clean water inlet 122, and the water outlet end of the single second flow channel 1431 is connected to the two first flow channels 1421 arranged in parallel, and the water outlet ends of the two first flow channels 1421 arranged in parallel are connected to the single second flow channel 1431, and the cycle is repeated alternately until the size of the flow channel body 141 meets the heat exchange requirements of the heat storage device 100.

[0050] Since the flow resistance of the purified water in the single second flow channel 1431 is relatively large, the flow time of the purified water in the second flow channel 1431 is increased, which can improve the heat exchange efficiency of the second flow unit. Moreover, since the two first flow channels 1421 arranged in parallel have a larger flow area in the first flow channel 1421 than the single second flow channel 1431, the flow resistance of the purified water is relatively small, and the flow rate is increased. By alternately arranging the second flow channel 1431 and the two first flow channels 1421, the heat exchange plate 140 can be balanced between the heat exchange capacity and the flow resistance, which can improve the heat exchange efficiency of the heat exchange plate 140.

[0051] Continue reading Figure 1 In some embodiments of the present invention, when the flow channel body 141 includes a first flow channel unit 142 and a second flow channel unit 143 connected to each other, it is equivalent to that the flow channel body 141 can be composed of multiple flow channels in series.

[0052] Along the height direction of the heat exchange plate 140 , the plurality of first flow channel units 142 are sequentially connected end to end, and the second flow channel unit 143 is connected to the head end or the tail end of the first flow channel unit 142 .

[0053] For example, a single second flow channel 1431 is connected to the clean water inlet 122, the water outlet of the single second flow channel 1431 is connected to two first flow channels 1421 arranged in parallel, the water outlets of the two first flow channels 1421 arranged in parallel continue to be connected to the two first flow channels 1421 arranged in parallel, and multiple two first flow channels 1421 arranged in parallel are connected in sequence until the size of the flow channel body 141 meets the heat exchange requirements of the heat storage device 100, and the clean water outlet 123 is connected to the two first flow channels 1421 arranged in parallel at the rear end. Through such an arrangement, the flow resistance of the clean water in the flow channel can be reduced as much as possible while ensuring the stability of the water inlet.

[0054] Continue reading Figure 1In some embodiments of the present invention, the clean water inlet 122 is disposed near the bottom of the heat exchange plate 140 , and the clean water outlet 123 is disposed near the top of the heat exchange plate 140 .

[0055] Equivalently, the water flow pattern in the heat exchange plate 140 is designed as a "bottom-in and top-out" pattern, that is, water enters from the bottom of the heat exchange plate 140 and exits from the top of the heat exchange plate 140. This can extend the time that the clean water stays in the flow channel body 141, achieve sufficient heat exchange, and prevent the clean water from quickly flowing out of the clean water outlet 123 due to gravity.

[0056] Figure 2 It is a structural schematic diagram of a second embodiment of a heat exchange plate provided by an embodiment of the utility model; Figure 3 It is a structural schematic diagram of a third embodiment of a heat exchange plate provided in an embodiment of the utility model.

[0057] See also Figure 2 and Figure 3 In some embodiments of the present invention, a heat exchange portion 144 is provided on the inner wall of at least one of the first flow channel 1421 and the second flow channel 1431 , and the heat exchange portion 144 is suitable for increasing the inner wall area of ​​the corresponding flow channel to increase the heat exchange area of ​​the heat exchange plate 140 .

[0058] Since the heat exchange plate 140 is a sheet metal part, different flow channels can be stamped on the heat exchange plate 140 according to actual needs, and the heat exchange parts 144 can be processed on the inner walls of the flow channels. These heat exchange parts 144 can increase the inner wall area of ​​the corresponding flow channels, significantly improve the flow heat transfer coefficient in the corresponding flow channels, and improve the heat exchange performance of the heat exchange plate 140.

[0059] The form of the heat exchange part 144 can be arbitrarily set according to the use requirements. For example, the heat exchange part 144 includes the following two settings.

[0060] The first setting form: continue to refer to Figure 2 The heat exchange portion 144 includes protrusions 1441, which are arranged at intervals on the inner wall of the first flow channel 1421 or the second flow channel 1431. By arranging the protrusions 1441 on the first flow channel 1421 or the second flow channel 1431, the contact area between the inner wall of the first flow channel 1421 or the second flow channel 1431 and the purified water can be increased, thereby increasing the heat exchange area of ​​the first flow channel 1421 or the second flow channel 1431, improving the heat exchange coefficient of the first flow channel 1421 or the second flow channel 1431, and thus improving the heat exchange performance of the heat exchange plate 140.

[0061] It can be understood that the protrusion 1441 protrudes inward relative to the inner wall of the first flow channel 1421 or the second flow channel 1431, and the protrusion 1441 is integrally formed with the inner wall of the first flow channel 1421 or the second flow channel 1431. Specifically, the protrusion 1441 is formed by punching the interior of the first flow channel 1421 or the second flow channel 1431 inward.

[0062] It should be noted that the protrusion 1441 is provided on the inner wall of the first flow channel 1421 or the second flow channel 1431 . The protrusion 1441 may be provided in each flow channel unit or only in some flow channel units.

[0063] Continue reading Figure 2 In some embodiments of the utility model, the inner wall of the first flow channel 1421 or the second flow channel 1431 is provided with a plurality of protrusions 1441, and the plurality of protrusions 1441 are arranged at intervals. By arranging the plurality of protrusions 1441 at intervals, the heat storage medium in each area can fully exchange heat with the clean water in the first flow channel 1421 or the second flow channel 1431, thereby further improving the heat exchange efficiency of the heat exchange plate 140.

[0064] It can be understood that the plurality of protrusions 1441 are arranged in at least one row along the length direction of the first flow channel 1421 or the second flow channel 1431 , and the distance between two adjacent protrusions 1441 in each row is equal.

[0065] It should be noted here that the distance between two adjacent protrusions 1441 is specifically determined according to the length of the flow channel unit and the size of the protrusion 1441. Of course, the distance between two adjacent protrusions 1441 may also be unequal, for example, more protrusions 1441 are set in the lower flow channel unit and fewer protrusions 1441 are set in the upper flow channel unit.

[0066] It is understandable that the cross-sectional width of the protrusion 1441 gradually increases or first increases and then decreases along the flow direction of the clean water, which can reduce the resistance of the protrusion 1441 to the clean water and reduce the output pressure requirement of the pump body.

[0067] In some embodiments of the present invention, the protrusion 1441 is hemispherical, and the cross-sectional width of the protrusion 1441 first increases and then decreases along the flow direction of the clean water. Multiple protrusions 1441 are arranged in multiple rows along the length direction of the first flow channel 1421 or the second flow channel 1431, and each row is provided with multiple protrusions 1441. The distance between two adjacent protrusions 1441 in the same row is equal.

[0068] In some embodiments of the utility model, when the cross-sectional width of the hemispherical protrusion 1441 first increases and then decreases along the flow direction of the clean water, multiple protrusions 1441 are arranged in a row along the length direction of the first flow channel 1421 or the second flow channel 1431, and multiple protrusions 1441 are set in each row, and the distance between two adjacent protrusions 1441 in the same row is equal.

[0069] The second setting form: See Figure 3 The heat exchange part 144 includes inclined ribs 1442, which are arranged in an array along the extension direction of the first flow channel 1421 or the second flow channel 1431. The ribs 1442 are arranged in a "V" shape, with the smaller end of the rib 1442 facing the direction of the clean water approaching, and the larger end of the rib 1442 facing the direction of the clean water moving away. This arrangement can reduce the resistance of the rib 1442 to the clean water.

[0070] Continue reading Figure 1 In some embodiments of the utility model, a first guide channel 145 and a second guide channel 146 are provided inside the heat exchange plate 140, and the clean water inlet 122 is connected with one end of the first flow channel 1421 or the second flow channel 1431 through the first guide channel 145, and the first guide channel 145 is suitable for guiding the clean water input into the clean water inlet 122 into the first flow channel 1421 or the second flow channel 1431.

[0071] The purified water outlet 123 is connected to the other end of the first flow channel 1421 or the second flow channel 1431 through the second guide channel 146 . The second guide channel 146 is suitable for guiding purified water after heat exchange in the first flow channel 1421 or the second flow channel 1431 into the purified water outlet 123 .

[0072] It should be noted here that the first guide channel 145 and the second guide channel 146 are grooves formed by stamping, and the first guide channel 145, the second guide channel 146 and each flow channel unit are stamped in the same manner.

[0073] Continue reading Figure 1 In some embodiments of the present invention, the flow area of ​​the first guide channel 145 gradually increases along the flow direction of the clean water, that is, the flow area of ​​the first guide channel 145 gradually increases from left to right, and the flow area at the right end of the first guide channel 145 is the largest and is the same as the flow area of ​​the flow channel unit.

[0074] After the clean water enters the first guide channel 145 through the clean water inlet 122, the flow area of ​​the first guide channel 145 gradually increases from left to right, which effectively reduces the resistance of the clean water. The flow area of ​​the second guide channel 146 gradually decreases along the flow direction of the clean water, that is, the flow area of ​​the second guide channel 146 gradually decreases from right to left. After the clean water heat exchange in the first flow channel 1421 or the second flow channel 1431 is completed, the clean water enters the second guide channel 146, and enters the clean water outlet 123 under the guidance of the second guide channel 146. Since the flow area of ​​the second guide channel 146 gradually decreases along the flow direction of the clean water, the second guide channel 146 can converge and guide the clean water, reducing the resistance when the clean water flows out.

[0075] Figure 4 It is a structural schematic diagram of a heat storage device provided in an embodiment of the utility model.

[0076] See also Figure 4 The utility model also provides a heat storage device. The heat storage device 100 includes a shell assembly 110 and the above-mentioned heat exchange plate 140.

[0077] The shell component 110 is a rectangular structure, and a heat storage chamber is constructed inside the shell component 110 , which is equivalent to the shell component 110 being a hollow structure, and the hollow cavity of the shell component 110 serves as the heat storage chamber.

[0078] The heat exchange plate 140 is installed in the heat storage chamber, and the gap between the outer wall of the heat exchange plate 140 and the inner wall of the heat storage chamber is filled with a heat storage medium. The heat storage medium can be water, paraffin or inorganic salt phase change material. 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. Therefore, the phase change material has a high energy density and a small volume. The phase change material is used for heat storage, the heat storage effect is better, and the structure volume of the heat storage device 100 is small.

[0079] See also Figure 1 In some embodiments of the present invention, the heat storage device further includes a heater 130, which is disposed in the heat storage chamber. The heater 130 is in contact with the heat storage medium and is used to store heat for the heat storage medium.

[0080] The heater 130 may be a U-shaped tube, and the heater 130 may be disposed below the heat exchange plate 140 , or may be disposed on the side of the heat exchange plate 140 , for storing heat in the heat storage medium.

[0081] Figure 5 It is a structural schematic diagram of a heater in a heat storage device provided in an embodiment of the utility model.

[0082] See also Figure 5 In some embodiments, the heater 130 includes a first heating part 131 and a second heating part 132 which are 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 plate 140, and the second heating part 132 is located on the side of the heat exchange plate 140.

[0083] 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°. The angle between the first heating part 131 and the second heating part 132 can be determined according to the structural space inside the thermal storage device 100.

[0084] When the first heating part 131 and the second heating part 132 are arranged at an angle to each other, a semi-enclosed structure accommodating space is limited between the first heating part 131 and the second heating part 132. It can be understood that the heat exchange plate 140 is located in the accommodating space enclosed by the first heating part 131 and the second heating part 132, and the first heating part 131 and the second heating part 132 are located on two adjacent sides of the heat exchange plate 140.

[0085] It is understandable that by storing heat in the heat storage medium filled between the heat exchange plate 140 and the inner wall of the heat storage chamber through the heater 130, the purified water flowing through the heat exchange plate 140 can reach a certain temperature, which is convenient for the subsequent heating component to heat immediately. Since 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 plate 140, and the second heating part 132 is located on the side of the heat exchange plate 140, it can not only heat the heat storage medium below the heat exchange plate 140, but also heat the heat storage medium on the side of the heat exchange plate 140 along the height of the heat exchange plate 140, so the heating effect is better, which is conducive to the temperature of the heat storage medium to be uniform.

[0086] In addition, since the first heating part 131 is arranged below the heat exchange plate 140 and the second heating part 132 is arranged on the side of the heat exchange plate 140 according to the internal space of the heat storage device 100, compared with the arrangement of the heater 130 in a spiral shape below the heat exchange plate 140, the arrangement of the heater 130 provided in the embodiment of the utility model can reduce the space occupied by the heater 130 in the heat storage device 100 while ensuring the heating effect, thereby reducing the volume of the heat storage device 100.

[0087] Continue reading Figure 5 In some embodiments of the present invention, the first heating part 131 and the second heating part 132 are vertically arranged, that is, the angle between the first heating part 131 and the second heating part 132 is 90°, the first heating part 131 is horizontally located below the heat exchange plate 140, and the second heating part 132 is vertically located on at least one side of the heat exchange plate 140.

[0088] In other words, the heater 130 as a whole is an "L"-shaped structure consisting of the first heating part 131 and the second heating part 132. The heater 130 can be a heating tube or a heating fin similar to the "L" shape. In this way, the structure and shape of the heater 130 are adapted to the overall shape of the thermal storage device 100, and the installation space is saved while meeting the heating requirements.

[0089] Since the structural shape of the heat exchange plate 140 is similar to that of the shell assembly 110, both of which are rectangular structures, the heat exchange plate 140 has four side surfaces that discharge the top surface, and the first heating part 131 is always located below the heat exchange plate 140. The second heating part 132 can be set on any side surface of the heat exchange plate 140, and can also be set on both sides of the heat exchange plate 140 at the same time.

[0090] See also Figure 5 In some embodiments of the utility model, the first heating part 131 includes a first heating pipe segment 1311, a second heating pipe segment 1312 and a connecting pipe segment 1313, one end of the first heating pipe segment 1311 and the second heating pipe segment 1312 are respectively connected to the second heating part 132, and the other ends of the first heating pipe segment 1311 and the second heating pipe segment 1312 are respectively connected to the connecting pipe segment 1313; from the position of the second heating part 132 to the direction of the connecting pipe segment 1313, the gap between the first heating pipe segment 1311 and the second heating pipe segment 1312 gradually increases.

[0091] This is equivalent to the first heating portion 131 being similar to a trapezoidal structure when viewed from above, and the width of the first heating portion 131 gradually increases from the position of the second heating portion 132 toward the direction away from the second heating portion 132. This can extend the size of the first heating portion 131, thereby extending the flow path of the heating medium flowing in the first heating portion 131 and increasing the heating effect of the first heating portion 131.

[0092] Since in the heat storage device 100 of the present invention, the clean water adopts the flow mode of "in from the bottom and out from the top", that is, water enters from the bottom of the heat storage device 100 and water exits from the top of the heat storage device 100. Therefore, during the heating process, the lower heat exchange plate 140 is connected to the clean water inlet, and the initial temperature is relatively low. The heating pipe provided by the present invention can allocate a higher heating power to the lower heat exchange plate 140, and can increase the temperature of the heat storage medium near the lower heat exchange plate 140. Because the temperature of the upper heat storage medium is relatively high, the heating pipe provided by the present invention can allocate a smaller heating power to the upper heat exchange plate 140, which is conducive to making the temperature of the heat storage medium around the heat exchange plate 140 more uniform and having a better heat storage effect.

[0093] It should be noted that, in the embodiment of the utility model, the first heating part 131 can be a single "U"-shaped tube that is integrally arranged, or can be formed by connecting multiple "U"-shaped tubes end to end in sequence. The specific arrangement can be determined according to actual use requirements.

[0094] Continue reading Figure 5 In some embodiments of the present invention, the connecting pipe segment 1313 includes a first curved pipe segment 1314, a second curved pipe segment 1315 and a straight section 1316. The straight section 1316 is located between the first curved pipe segment 1314 and the second curved pipe segment 1315, and is connected to the first curved pipe segment 1314 and the second curved pipe segment 1315 respectively. The first curved pipe segment 1314 is connected to the first heating pipe segment 1311, and the second curved pipe segment 1315 is connected to the second heating pipe segment 1312.

[0095] Equivalently, the connecting pipe section 1313 is composed of three sections, the straight section 1316 is connected to the first heating pipe section 1311 through the first curved pipe section 1314, and the straight section 1316 is connected to the second heating pipe section 1312 through the second curved pipe section 1315. This arrangement can not only meet the processing requirements, but also extend the structural size of the first heating part 131, thereby improving the heating efficiency.

[0096] In addition, if space permits, the connecting pipe section 1313 may also be composed of a plurality of bent pipes connected end to end in sequence, and the structural dimensions of the first heating part 131 may be further extended by reversing the bent pipes, thereby improving the heating efficiency.

[0097] 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.

[0098] 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.

[0099] When the drinking water device is powered on, it first enters the heat storage mode, 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 device 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 the heater 130 needs to be turned on to store heat for the heat storage medium.

[0100] When the user takes water, the drinking water device enters the water outlet mode, and the water pump pumps the purified water from the water supply component to the heat storage device 100 to be preheated to a certain temperature, and then the preheated purified 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 purified water can be instantly heated by the heating component, meeting the requirement of rapid water extraction.

[0101] In addition, in order to save the material cost of the drinking water equipment and omit the setting of the heater 130, the drinking water equipment can also include a reversing valve, which is arranged at the water outlet end of the heating component, and a self-circulating pipeline is connected to the pipeline between the reversing valve and the water outlet end of the water pump.

[0102] The drinking water equipment can use the heating component to charge the heat storage medium in a self-circulating manner, that is, the heating component heats the water to a certain temperature and then inputs it into the self-circulating pipeline. The high-temperature water transfers energy to the heat storage medium during the process of flowing through the heat exchange plate 140 through the self-circulating pipeline. After the water temperature drops, it flows into the heating component for circulation heating.

[0103] 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.
