[0040] Figure 1 It is one of the system schematic diagrams of the drinking water equipment provided in the embodiment of the utility model.

[0041] 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.

[0042] Among them, the heat storage device 100 includes a shell component 110 and a heat exchange component 120 and a heater 130 arranged in the shell component 110. The shell component 110 is a rectangular structure, and a heat storage chamber 1111 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 1111.

[0043] The heat exchange component 120 is installed in the heat storage chamber 1111, and the gap between the outer wall of the heat exchange component 120 and the inner wall of the heat storage chamber 1111 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.

[0044] The heater 130 is disposed in the heat storage chamber 1111, 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 includes a first heating part 131 and a second heating part 132 connected to each other, and 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.

[0045] 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.

[0046] 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 component 120 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 component 120.

[0047] 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 water inlet 220 in the water supply component 210 to the heat storage device 100. 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.

[0048] When the drinking water device 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 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.

[0049] When the user takes water, the drinking water device enters the water outlet mode, and the water pump 220 pumps the purified water of the water supply component 210 to the heat storage device 100 to be preheated to a certain temperature, and then the preheated purified 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 pipe, the purified water can be heated immediately after passing through the heating component 300, meeting the use requirement of rapid water extraction.

[0050] It can be understood that the drinking water equipment provided by the embodiment of the utility model, the heat storage device 100 includes a shell component 110 and a heat exchange component 120 and a heater 130 arranged in the shell component 110. By arranging the heater 130 in the heat storage chamber 1111 of the shell component 110, the heat storage medium filled between the heat exchange component 120 and the inner wall of the heat storage chamber 1111 is stored by the heater 130, so that the purified water flowing through the heat exchange component 120 can reach a certain temperature, which is convenient for the subsequent instant heating by the heating component. Since the heater 130 includes a first heating part 131 and a second heating part 132 that 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 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 a uniform temperature of the heat storage medium.

[0051] 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, compared with the arrangement of the heater 130 in a spiral shape below the heat exchange component 120, the arrangement method 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 drinking water equipment.

[0052] Figure 2 This is the second system schematic diagram of the drinking water equipment provided by the embodiment of the utility model.

[0053] See also Figure 2 In some embodiments of the utility model, the drinking water equipment also includes a reversing valve 400, which is arranged on the water 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.

[0054] The drinking water equipment can charge the heat storage medium in a self-circulating manner, that is, the heating component 300 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 component 120 through the self-circulating pipeline. After the water temperature drops, it flows into the heating component 300 for circulation heating.

[0055] This arrangement can expand the use scenarios of the drinking water equipment. For example, when the water temperature required by the water component is high, the water pump 220 sends the clean water pump 220 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 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 heated instantly after passing through the heating component 300, meeting the use requirements of fast water extraction. When the water temperature required by the water component does not need to be too high, the drinking water equipment can charge the heat storage medium in a self-circulating manner.

[0056] In addition, according to user needs, the heater 130 in the heat storage device 100 can be omitted to simplify the system structure and reduce production costs. The specific settings can be adaptively adjusted according to actual market needs.

[0057] Continue to refer to 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.

[0058] 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.

[0059] After the heater 130 in the heat storage device 100 is selected, 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.

[0060] Continue to refer to 1 and Figure 2 In some embodiments of the present invention, the drinking water device further comprises a third temperature detection component 700, which is disposed on the heating component 300 and is used to detect the temperature of the heating component 300. Thus, the heating efficiency of the heating component 300 can be controlled according to the water outlet temperature T2 of the heating component 300.

[0061] continue Figure 2 In some embodiments of the utility model, the drinking water device further includes a bypass pipe 900, one end of which is connected to the water inlet of the heat storage device 100, and the other end of which is connected to the water outlet of the heat storage device 100. This is equivalent to the bypass pipe 900 being arranged in parallel at both ends of the heat storage device 100, and the purified water provided by the water supply component 200 can be divided into two paths to enter the heating component 300.

[0062] This arrangement can not only meet the requirements of different water temperatures, for example, when the drinking water device does not need high-temperature water, the purified water can directly enter the heating component 300 from the bypass pipe 900, and the purified water can also enter the heating component 300 through the heat storage device 100 and the bypass pipe 900 at the same time; and it can ensure the normal use of the drinking water device while the heat storage device 100 is replaced or repaired. In addition, a control valve is provided on the bypass pipe 900, and the control valve is used to control the bypass pipe 900 to be turned on or off.

[0063] Figure 3 It is a schematic diagram of the structure explosion of the heat storage device provided by the embodiment of the utility model; Figure 4 It is a partial structural schematic diagram of the heat storage device provided by the embodiment of the utility model; Figure 5 It is a side view of the partial structure of the heat storage device provided in an embodiment of the utility model.

[0064] Continue reading Figure 3 and 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 component 120, and the second heating part 132 is vertically located on at least one side of the heat exchange component 120.

[0065] 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.

[0066] Since the structural shape of the heat exchange component 120 is similar to that of the shell component 110, both of which are rectangular structures, the heat exchange component 120 has four side surfaces that discharge the top surface, and the first heating part 131 is always located below the heat exchange component 120. The second heating part 132 can be set on any side surface of the heat exchange component 120, and can also be set on both sides of the heat exchange component 120 at the same time.

[0067] Figure 6 It is a schematic diagram of the structure of the heater 130 in the heat storage device 100 provided in an embodiment of the present utility model.

[0068] See also Figure 6 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.

[0069] 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.

[0070] 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 the bottom of the heat storage device 100 and water exits the top of the heat storage device 100. Therefore, during the heating process, the lower heat exchange component 120 is connected to the clean water inlet 122, and the initial temperature is low. The heating pipe provided by the present invention can allocate higher heating power to the lower heat exchange component 120, and can increase the temperature of the heat storage medium near the lower heat exchange component 120. Because the temperature of the upper heat storage medium is higher, the heating pipe provided by the present invention can allocate smaller heating power to the upper heat exchange component 120, which is conducive to making the temperature of the heat storage medium around the heat exchange component 120 more uniform and the heat storage effect is better.

[0071] 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.

[0072] Continue reading Figure 6In 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.

[0073] 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.

[0074] 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.

[0075] Continue reading Figures 3 to 5 In some embodiments of the utility model, at least two groups of heat exchange pipes are arranged in parallel inside the heat exchange component 120. Compared with a single heat exchange pipe with the same flow area arranged in the heat exchange component 120, the flow area of ​​the heat exchange pipe can be effectively increased, and the flow resistance of the clean water in the heat exchange pipe can be reduced. It is equivalent to that at least two groups of heat exchange pipes are arranged inside the heat exchange component 120, and three groups of heat exchange pipes, four groups of heat exchange pipes, etc. can also be arranged in parallel. The number limit of the heat exchange pipes can be determined according to actual use requirements. The heat exchange component 120 is also 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 respectively connected to each group of heat exchange pipes.

[0076] With this arrangement, when the heat storage device 100 is used in a drinking water device, such as an instant hot water dispenser, the flow area of ​​the heat exchange pipe in the heat exchange component 120 increases, and the flow resistance of the clean water in the heat exchange pipe decreases. This can increase the water flow rate of the instant hot water dispenser accordingly, shorten the time it takes for users to get water during use, and provide a better user experience.

[0077] The heat exchange assembly 120 may be composed of a plurality of heat exchange plates or a plurality of heat exchange tubes 121. When the heat exchange assembly 120 is composed of a plurality of heat exchange tubes 121, mutually independent heat exchange pipes are formed in each heat exchange tube 121, and the plurality of heat exchange tubes 121 may share a clean water inlet 122 and a clean water outlet 123, or the plurality of heat exchange tubes 121 may be independently provided with a clean water inlet 122 and a clean water outlet 123.

[0078] When the plurality of heat exchange tubes 121 can also be independently provided with a clean water inlet 122 and a clean water outlet 123, the clean water inlet 122 and the clean water outlet 123 of each heat exchange tube 121 are provided in the same direction, so that the clean water inlet 122 and the clean water outlet 123 are conveniently connected to other structures of the instant hot water dispenser, wherein the heat exchange tube 121 can be a stainless steel tube. When the heat exchange assembly 120 is composed of a plurality of heat exchange plates, a flow channel can be stamped on each heat exchange plate, and when two heat exchange plates arranged opposite to each other are assembled, a closed heat exchange pipe is formed between the two heat exchange plates.

[0079] It is understandable that the heat storage device 100 provided in the embodiment of the utility model can effectively increase the flow area of ​​the heat exchange pipe and reduce the flow resistance of the clean water in the heat exchange pipe by arranging at least two groups of heat exchange pipes in parallel in the heat exchange component 120, compared with the heat exchange component 120 arranging a single heat exchange pipe with the same flow area, and the heat exchange component 120 is also 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 respectively connected to each group of heat exchange pipes. When the heat storage device 100 is applied to drinking water equipment, such as an instant hot water dispenser, due to the increase in the flow area of ​​the heat exchange pipe in the heat exchange component 120, the flow resistance of the clean water in the heat exchange pipe is reduced, and the water 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.

[0080] Continue reading Figure 3 In some embodiments of the present invention, the heat exchange component 120 includes at least two heat exchange tubes 121 arranged side by side, that is, at least two heat exchange tubes 121 are arranged in the heat exchange component 120, and the two heat exchange tubes 121 are arranged in parallel along the width direction of the heat storage device 100. A flow channel is constructed in each heat exchange tube 121, and the cross-sectional area of ​​each flow channel can be the same. Of course, in some embodiments, the cross-sectional area of ​​each flow channel can also be different.

[0081] With this arrangement, when clean water flows into each heat exchange pipe from the clean water inlet 122 , since the cross-sectional area and water level of each heat exchange pipe are the same, the clean water has a stable flow rate in each heat exchange pipe, which can ensure a better heat exchange effect of the clean water in the heat exchange tube 121 .

[0082] Figure 7 It is a schematic diagram of the structure of the heat exchange tube 121 in the heat storage device 100 provided in an embodiment of the utility model.

[0083] Continue reading Figure 7In some embodiments of the utility model, each heat exchange tube 121 includes a plurality of stacked heat exchange units 1211, and the plurality of heat exchange units 1211 are stacked in sequence along the height direction of the shell assembly 110, and two adjacent heat exchange units 1211 are connected end to end through a reversing elbow 1212. In this way, the water level and flow area of ​​the clean water in the heat exchange units 1211 on the same layer are the same, so that the clean water can have a stable flow rate in each heat exchange pipe, so as to ensure a better heat exchange effect of the clean water in the heat exchange tube 121.

[0084] Among them, the clean water inlet 122 is arranged at the lower heat exchange unit 1211, which is equivalent to the clean water inlet 122 being connected to the heat exchange unit 1211 located at the bottom layer; the clean water outlet 123 is arranged at the upper heat exchange unit 1211, which is equivalent to the clean water outlet 123 being connected to the heat exchange unit 1211 located at the top layer.

[0085] That is, the water flow pattern of each heat exchange tube 121 is designed as a "bottom-in and top-out" pattern, that is, water enters the bottom of the heat storage device 100 and exits the top of the heat storage device 100. The clean water can stay in the heat exchange pipe for a longer time to achieve sufficient heat exchange and avoid the clean water from flowing out of the clean water outlet 123 quickly due to gravity. When the heat storage device 100 is exchanging heat, the average heat transfer temperature difference of the heat exchange tube 121 can be reduced, so that better heat exchange performance can be obtained on the basis of the heat storage device 100 of the same size, and the volume of the heat storage device 100 can be reduced under the same heat exchange performance requirements.

[0086] Continue reading Figure 7 In some embodiments of the present invention, each heat exchange unit 1211 includes a first heat exchange pipe segment 1213, a second heat exchange pipe segment 1214 and a connecting pipe segment 1215. The first heat exchange pipe segment 1213 and the second heat exchange pipe segment 1214 are arranged in parallel, one end of the connecting pipe segment 1215 is connected to the first heat exchange pipe segment 1213, and the other end of the connecting pipe segment 1215 is connected to the second heat exchange pipe segment 1214.

[0087] It is equivalent to that each heat exchange unit 1211 is arranged in a "U" shape, that is, each heat exchange unit 1211 can be a "U" shaped tube, and the "U" shaped tube is arranged in a horizontal direction. In this way, when the clean water inlet 122 is arranged in the heat exchange unit 1211, the clean water entering from the clean water inlet 122 can more smoothly enter the interior of the heat exchange pipe for heat exchange, thereby preventing the clean water from flowing back under the action of gravity.

[0088] Due to such an arrangement, it is equivalent to forming four groups of parallel heat exchange tubes 121 at the same water level in the heat storage chamber 1111 in a heat storage device 100 along the width direction of the heat storage device 100, which can increase the contact area between the heat exchange tubes 121 and the heat storage medium, and improve the heat exchange effect of the heat exchange tubes 121. Moreover, this can reduce the volume of the heat storage device 100. When the heat storage device 100 is applied to an instant hot water dispenser, it occupies less internal space of the instant hot water dispenser, and can also make the instant hot water dispenser tend to be miniature in design.

[0089] It should be noted that in the embodiment of the utility model, the connecting pipe section 1215 is a curved pipe, which mainly plays the role of reversing and diverting. Two adjacent connecting pipe sections 1215 are arranged in parallel, and the connecting pipe section 1215 can be a straight pipe or a "U"-shaped pipe. Each connecting pipe section 1215 can be arranged in a vertical direction, and each connecting pipe section 1215 is arranged in parallel with each other; in addition, two adjacent connecting pipe sections 1215 can also be staggered along the width direction of the heat storage device 100, so that the flow area of ​​the heat exchange tube 121 can be increased, and the volume of the heat storage device 100 can be reduced.

[0090] Continue reading Figures 3 to 5 In some embodiments of the utility model, the heater 130 can also be a heating wire or a constant temperature PTC, etc. The heater 130 is arranged in the heat storage chamber 1111, 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 heat storage medium. After the heat storage medium is heated to a specified temperature, the heat storage medium is kept warm.

[0091] Continue reading Figure 3 In some embodiments of the present invention, the shell assembly 110 includes a shell body 111 and a cover body 112, the cover body 112 is sealed to the shell body 111, and the heat storage chamber 1111 is formed inside the shell body 111. The shell body 111 and the cover body 112 can be made of heat-resistant plastic, stainless steel and other materials.

[0092] In other words, the shell assembly 110 is composed of a shell body 111 and a cover body 112. The shell body 111 can be formed by integral stamping, and the cover body 112 can be connected to the shell body 111 by detachable connectors such as buckles, screws or bolts, and a seal is provided between the shell body 111 and the cover body 112 to seal the heat storage chamber 1111. In addition, the shell body 111 and the cover body 112 can also be fixed by welding.

[0093] Compared with the related art, in which the shell assembly 110 adopts a box body and two cover plates arranged at both ends of the box body, the shell assembly 110 provided by the utility model can simplify the parts arrangement, facilitate processing, facilitate disassembly and installation, and facilitate after-sales maintenance.

[0094] Continue reading Figure 4 In some embodiments of the present invention, the side wall of the shell body 111 is provided with a first opening 1112 corresponding to the position of the clean water inlet 122 , and the side wall of the shell body 111 is provided with a second opening 1113 corresponding to the position of the clean water outlet 123 .

[0095] Since the water flow pattern of each heat exchange tube 121 is designed as "in from the bottom and out from the top", the height of the second opening 1113 is greater than the height of the first opening 1112; wherein the clean water inlet 122 is provided through the first opening 1112 and extends out of the outer side of the shell body 111, and the clean water outlet 123 is provided through the second opening 1113 and extends out of the shell body 111. This arrangement enables the clean water inlet 122 to be directly connected to the external water supply component 200, and enables the clean water outlet 123 to be directly connected to the heating component 300, which can simplify the installation process and improve the installation efficiency.

[0096] It should be noted that the first opening 1112 and the second opening 1113 may be holes opened on the shell body 111 , or may be tubular structures extending from the shell body 111 .

[0097] In addition, a heat storage medium supply port 113 and an air outlet 114 are also provided through the top of the shell body 111. 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 body 111, or a tubular structure provided on the shell body 111. The air outlet 114 is used to discharge the gas from the heat storage chamber 1111. Similarly, the air outlet 114 can be a hole opened on the shell body 111, or a tubular structure provided on the shell body 111.

[0098] In addition, a liquid level detection component 115 is provided on the top of the shell body 111, and the liquid level detection component 115 is used to monitor 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 115 can be a structure such as a water level probe.

[0099] It should be noted that the embodiment of the utility model takes water as the heat storage medium as an example. 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 body 111.

[0100] In addition, a temperature measuring component 116 and a temperature control protection component 117 are provided on the shell body 111. The temperature measuring component 116 is a thermocouple temperature measuring tube for detecting the temperature of the heat storage medium in the shell body 111. 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 heat storage medium to play a protective role.

[0101] 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.
