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.

[0042] In one embodiment of the utility model, a heater and a water dispenser are provided. The heater is provided with a heating tube and a jet assembly. The jet assembly can guide the fluid to flow toward the heating tube, which can enhance the heat exchange effect between the fluid and the heating wall surface, so that the fluid can obtain more heat during the flow process, thereby improving the heat exchange effect. Figures 1 to 9 The heater and water dispenser in this embodiment are further described in the figure.

[0043] Specifically, if Figure 1 , Figure 2 and Figure 3 As shown, the heater in this embodiment includes: a heating tube 10 and a jet component 20.

[0044] The heating tube 10 has a liquid inlet port and a liquid outlet port.

[0045] Exemplarily, the heating tube 10 can be constructed as a hollow cylindrical structure, with openings provided at both ends of the heating tube 10, respectively, and the openings at the two ends are a liquid inlet port and a liquid outlet port, respectively. External fluids such as drinking water can enter the tube cavity of the heating tube 10 through the liquid inlet port. After the heating tube 10 heats the fluid, the heated fluid can leave the tube cavity of the heating tube 10 through the liquid outlet port to be supplied to the outside.

[0046] The heating tube 10 is a functional element capable of heating the fluid. It can heat the fluid by electric heating methods such as thick film heating, quartz tube heating, nanofilm heating, cast aluminum heating, stainless steel wire winding heating, etc., or it can also heat the fluid by heat exchange methods such as steam heating and combustion heating.

[0047] In this embodiment, the heating tube 10 includes: a heating tube body and a heating element, wherein the heating element is disposed on the heating tube body and configured to heat the heating tube body.

[0048] In one embodiment, when electric heating is adopted, the heating tube 10 can be made of metal materials, such as stainless steel, cast aluminum, etc., and the heating element can be a thick film resistor heater, a nano-electronic film heater or a stainless steel heater, etc., and the heating element is fitted on the outside of the heating tube 10. When it is necessary to heat the fluid in the heating tube 10, these heaters can be powered on, and then these heaters can generate high temperature and heat up the heating tube 10. When the fluid flows in the heating tube 10, the fluid can be heated.

[0049] In one embodiment, when heat exchange heating is adopted, the heating tube 10 can be made of metal material, such as stainless steel, and the heating element can be a gas heating device, which is arranged outside the heating tube 10. When it is necessary to heat the fluid in the heating tube 10, gas can be supplied to the gas heating device, and the gas heating device can ignite the gas after obtaining the gas to make it burn, thereby heating the heating tube to increase its temperature. When the fluid flows in the heating tube 10, the fluid can also be heated.

[0050] like Figure 3 As shown, the jet component 20 is arranged in the heating tube 10 and forms a water gap between the jet component 20 and the heating tube 10. The jet component 20 has a jet cavity and a water inlet and a plurality of jet holes 21 connected to the jet cavity. The water inlet faces the liquid inlet port, and the jet direction of the jet hole 21 faces the inner wall of the heating tube 10. The distance L between the outer wall surface of the jet component and the inner wall surface of the heating tube 10 is 1 to 5 mm.

[0051] It can be understood that after the fluid enters the gap between the jet assembly 20 and the heating tube 10, the fluid can form a liquid layer with a certain thickness. On the one hand, the fluid can contact the inner wall of the heating tube 10 to receive heat, and on the other hand, it will flow toward the liquid outlet port. At this time, in order to ensure the water outlet efficiency while taking into account the heating efficiency of the liquid, the thickness of the liquid layer cannot be too large, nor can it be too small.

[0052] For example, when the thickness of the liquid layer between the jet component 20 and the heating tube 10 is too large, the heat in the liquid layer cannot be effectively transferred in its thickness direction, which may cause the temperature of the liquid to fail to meet the use requirements. When the thickness of the liquid layer between the jet component 20 and the heating tube 10 is too small, the flow rate of the liquid in the axial direction M of the heating tube 10 is small, which may cause the external output flow rate of the liquid to be too small.

[0053] Based on this, in this embodiment, through experimental research, combined with the flow rate of the liquid in the heating tube 10, as shown in FIG. Figure 4 As shown, the distance L between the outer wall of the jet assembly 20 and the inner wall of the heating tube 10 can be 1 to 5 mm. It can be understood that the distance L can be 1 mm, 5 mm, or any value between 1 and 5 mm.

[0054] In actual application scenarios, when it is necessary to heat drinking water or other fluids in a water dispenser with the help of the heater in this embodiment, the fluid to be heated can enter the heating tube 10 through the liquid inlet port, and the heating tube 10 can heat the fluid in the heating tube 10. When the fluid flows in the heating tube 10 toward the liquid outlet port, part of the fluid will enter the jet cavity through the water inlet. Under the pressure of the fluid, the fluid in the jet cavity will flow outward in the radial direction of the heating tube 10 and enter the water gap through the jet hole 21. Moreover, the distance L between the jet component 20 and the heating tube 10 is 1 to 5 mm. At this time, the fluid in the heating tube 10 can receive the heat of the heating tube 10 in a liquid layer 1 to 5 mm thick. Finally, these fluids flow out through the liquid outlet port.

[0055] It can be seen that in the embodiment of the utility model, by arranging the jet component 20 in the heating tube 10, the fluid in the heating tube 10 can be guided to spray toward the inner wall of the heating tube 10, so that the fluid can fully exchange heat with the heating tube 10, and by limiting the distance L between the jet component 20 and the heating tube 10 to 1 to 5 mm, a liquid layer with a thickness of 1 to 5 mm can be formed. While ensuring a certain flow rate, all the fluids can fully receive the heat from the heating tube 10, and can take into account both the flow supply demand and the heat acquisition efficiency, thereby ultimately improving the heat exchange effect.

[0056] Furthermore, in this embodiment, the jet assembly 20 includes: a central column 22, a water baffle 23 and a jet tube 24, the water baffle 23 is fixedly sleeved on the central column 22, one end of the jet tube 24 faces the liquid inlet port to form a water inlet, the other end of the jet tube 24 is connected to the water baffle 23, the jet hole 21 is located on the wall of the jet tube 24, and a jet cavity is formed between the inner wall of the jet tube 24 and the outer wall of the central column 22.

[0057] For example, Figure 3 As shown, the central column 22 has a certain length and can be made of metal material, such as stainless steel. The central column 22 is coaxially arranged in the heating tube 10, and the axis of the central column 22 is substantially parallel to the axis of the heating tube 10. Optionally, the central column 22 is coaxially arranged at the axis center position of the heating tube 10.

[0058] Moreover, the central column 22 can be either a hollow tubular structure or a solid columnar structure. In the present embodiment, in order to reduce the overall weight of the heater, the central column 22 is a hollow tubular structure.

[0059] Furthermore, if Figure 3 As shown, a heating chamber 11 is formed between the outer wall of the central column 22 and the inner wall of the heating tube 10, and fluids such as drinking water can flow in the heating chamber 11. For example, the fluid entering the heating chamber 11 through the liquid inlet port can flow from one end of the heating tube 10 to the other end in the heating chamber 11 and leave the heating chamber 11 through the liquid outlet port.

[0060] The central column 22 is mainly used to support the water baffle 23, and the central column 22 can be fixedly arranged in the heating tube 10. In this embodiment, the central column 22 is detachably arranged in the heating tube 10, and both ends of the central column 22 can be fixed by means of a connecting structure. Alternatively, the central column 22 can also be directly fixedly arranged inside the heating tube 10 by means of other structural members.

[0061] The water baffle 23 is roughly constructed as a circular plate structure with a certain thickness. The water baffle 23 is sleeved onto the outer wall of the center column 22 and extends outward in the radial direction of the center column 22. One end of the jet tube 24 is connected to the water baffle 23, and the other end extends toward the liquid inlet port of the heating tube. The jet tube 24 is provided with a jet hole 21.

[0062] The jet tube 24 can force the fluid to flow outward toward the inner wall of the heating tube 10 in the radial direction of the center column 22 during the process of the fluid flowing from one end of the heating tube 10 to the other end, so that the fluid can contact the inner wall of the heating tube 10 and the fluid can obtain heat from the heating tube 10, thereby improving the heat exchange efficiency.

[0063] In this embodiment, in order to allow more fluid to flow outward in the radial direction of the central column 22 toward the inner wall of the heating tube 10, the jet tube 24 is roughly constructed as a hollow cylindrical structure. The jet tube 24 is sleeved on the outer periphery of the central column 22, and one end of the jet tube 24 is connected to the water baffle 23, and the other end extends toward the liquid inlet port.

[0064] In other embodiments, a plurality of jet tubes 24 may also be disposed around the outer circumference of the central column 22 .

[0065] The jet hole 21 is arranged on the jet tube 24 . The jet hole 21 may be a circular hole. The jet hole 21 enables the jet cavity and the water gap to communicate with each other.

[0066] In actual use, in the process of the fluid in the heating chamber 11 flowing from one end to the other end of the heating tube 10, part of the fluid can directly enter the water gap, and the rest of the fluid enters the jet chamber through the water inlet. The water baffle 23 can block these fluids, so that only the jet hole 21 in the radial direction of the center column 22 enters the water gap. The fluid in the water gap can fully obtain the heat of the heating tube 10 to achieve heating.

[0067] Moreover, a sealed connection can be achieved between the water baffle 23 and the center column 22, so that all the fluid in the jet cavity can flow outward in the radial direction of the center column 22 toward the inner wall of the heating tube 10 and enter the water gap.

[0068] In one embodiment, the center column 22, the water baffle 23 and the jet tube 24 are an integrated structure. For example, the center column 22, the water baffle 23 and the jet tube 24 can all be made of metal materials, such as stainless steel. The water baffle 23 can be fixedly connected to the center column 22 by welding or the like, and the jet tube 24 can be integrally formed with the water baffle 23.

[0069] In yet another embodiment, the center column 22, the water baffle plate 23 and the jet tube 24 may be directly fixedly connected by means of bolts or other structures.

[0070] In this embodiment, the heating tube 10 is a tubular structure with a certain length. In order to ensure that the fluid in each part of the heating tube 10 in the axial direction M can contact the inner wall of the heating tube 10 under the guidance of the jet assembly 20 to improve the heat exchange effect, Figure 2 As shown, there are multiple jet assemblies 20, and the multiple jet assemblies 20 are sequentially spaced along the axial direction of the central column 22. It can be understood that Figure 3 As shown, the axial direction of the central column 22 is parallel to the axial direction M of the heating tube 10 .

[0071] For example, Figure 5As shown, multiple jet assemblies 20 can share the same central column 22, that is, in the axial direction of the central column 22, the structure formed by the water baffle 23 and the jet tube 24 can be arranged in sequence along the axial direction M of the heating tube 10, and there is a certain gap between adjacent jet tubes 24.

[0072] In practice, Figure 3 As shown, when the fluid in the heating chamber 11 flows from one end to the other end of the heating tube 10, the fluid will enter the jet chamber of the first jet tube 24, and then flow toward the heating tube 10 through the jet hole 21 of the first jet tube 24 to achieve initial heating. After that, the fluid will enter the jet chamber of the second jet tube 24, and then flow toward the heating tube 10 through the jet hole 21 of the second jet tube 24 to achieve reheating. This reciprocating cycle will eventually achieve overall heating of the fluid in the heating chamber 11.

[0073] In one embodiment, in order to allow the fluid in the heating chamber 11 to fully contact the inner wall of the heating tube 10 and allow the fluid to obtain more heat, Figure 3 As shown, the gap distance between the jet tube 24 and the central column 22 is greater than the gap distance between the jet tube 24 and the heating tube 10 .

[0074] In one embodiment, Figure 6 As shown, the distance L between the outer wall of the jet tube 24 and the inner wall of the heating tube 10 can be 1 mm. At this time, a 1 mm thick liquid layer can be formed between the jet tube 24 and the heating tube 10. The liquid layer is relatively thin, and the fluid in the liquid layer can quickly heat up under the heat transfer of the heating tube 10.

[0075] In one embodiment, Figure 7 As shown, the distance L between the outer wall of the jet tube 24 and the inner wall of the heating tube 10 can be 2 mm. At this time, a 2 mm thick liquid layer can be formed between the jet tube 24 and the heating tube 10. The thickness of the liquid layer is moderate, and the fluid in the liquid layer can quickly heat up under the heat transfer of the heating tube 10, and the fluid has a certain flow rate.

[0076] In one embodiment, Figure 8 As shown, the distance L between the outer wall of the jet tube 24 and the inner wall of the heating tube 10 can be 4 mm. At this time, a 4 mm thick liquid layer can be formed between the jet tube 24 and the heating tube 10. The thickness of the liquid layer is relatively thick, and the fluid in the liquid layer has sufficient flow rate and can be quickly supplied to the outside. Moreover, the fluid can also be quickly heated under the heat transfer of the heating tube 10.

[0077] Moreover, if Figures 6 to 8As shown, the outer periphery of the end of the jet tube 24 away from the water retaining plate 31 is provided with a water retaining wing 25. The water retaining wing 25 can be constructed as an annular flange structure protruding from the outer wall surface of the jet tube 24 and extending along the circumferential direction of the jet tube 24. For example, the water retaining wing 25 can be integrally formed with the jet tube 24.

[0078] In one embodiment, the distance between the outer wall surface of at least a portion of the jet assembly 20 and the inner wall surface of the heating tube 10 is different.

[0079] It can be understood that a plurality of heating tubes 24 are provided in the heating tube 10 , and the distances between the plurality of heating tubes 24 and the inner wall surface of the heating tube 10 are different according to different heating requirements.

[0080] In one embodiment, in the direction from the liquid inlet port toward the liquid outlet port, the distance between the outer wall surface of the jet assembly 20 and the inner wall surface of the heating tube 10 gradually increases.

[0081] It can be understood that in order to allow the fluid to be better heated during the heating process and ensure that the fluid in the water gap can contact the inner wall surface of the heating tube 10 more, a plurality of heating tubes 24 are arranged in the heating tube 10. In the direction from the liquid inlet port to the liquid outlet port, the distance between the outer wall surface of the heating tube 24 and the inner wall surface of the heating tube 10 gradually increases.

[0082] In one embodiment, the distance between the outer wall surface of a single jet assembly 20 and the inner wall surface of the heating tube 10 gradually increases.

[0083] It can be understood that for a single jet tube 24, there is an angle between the outer wall surface of the jet tube 24 and the axial direction M of the heating tube 10, and in the direction from the liquid inlet port toward the liquid outlet port, the distance between the outer wall surface of the jet tube 24 and the axial direction M of the heating tube 10 can gradually increase.

[0084] At this time, the fluid entering the water gap through the jet hole 21 can be better heated.

[0085] In one embodiment, in order to ensure that the fluid in the jet cavity can effectively flow toward the inner wall of the heating tube 10 , the hole axis of the jet hole 21 is perpendicular to the axial direction of the heating tube 10 .

[0086] In one embodiment, in order to allow the fluid in the jet cavity to effectively flow to the heating tube 10, as shown in FIG. Figure 2 and Figure 3 As shown, there are multiple jet holes 21 , wherein the multiple jet holes 21 are sequentially spaced apart along the circumferential direction of the jet tube 24 ; and / or the multiple jet holes 21 are sequentially spaced apart along the axial direction of the jet tube 24 .

[0087] Exemplarily, when a plurality of jet holes 21 are arranged at intervals along the circumferential direction of the jet tube 24, for example, 12 to 22 jet holes 21 are arranged at intervals along the circumferential direction of the jet tube 24, the fluid in the jet chamber can flow from the circumferential side of the jet tube 24 to the heating chamber 11 via the plurality of jet holes 21, so that the fluid can contact the inner wall of the heating tube 10 in the circumferential direction of the jet tube 24 to obtain more heat. When a plurality of jet holes 21 are arranged at intervals along the axial direction of the jet tube 24, for example, 2 to 4 jet holes 21 are arranged at intervals along the axial direction of the jet tube 24, the fluid in the jet chamber can flow to the heating chamber 11 in the axial direction of the jet tube 24 via the plurality of jet holes 21, avoiding excessive accumulation of the fluid inside the jet tube 24, which can improve the flow efficiency of the fluid, and also allow the fluid inside the jet tube 24 to contact the inner wall of the heating tube 10 in advance, which can improve the heat exchange efficiency of the fluid. It can be understood that the axial direction of the jet tube 24 is parallel to the axial direction M of the heating tube 10 .

[0088] Exemplarily, the respective axial lines of the central column 22, the jet tube 24 and the heating tube 10 are substantially collinear with each other, and in the radial direction of the central column 22, the distance between the outer wall of the central column 22 and the inner wall of the jet tube 24 is greater than the distance between the outer wall of the jet tube 24 and the inner wall of the heating tube 10. Optionally, the ratio of the distance between the outer wall of the central column 22 and the inner wall of the jet tube 24 to the distance between the outer wall of the jet tube 24 and the inner wall of the heating tube 10 is 3 to 5.

[0089] Therefore, in practice, when the fluid in the heating chamber 11 flows from one end to the other end of the heating tube 10, more fluid can enter the jet chamber, and these fluids then enter the water gap through the jet holes 21, thereby ensuring that more fluid can flow toward the inner wall of the heating tube 10, achieving more heat exchange, thereby improving the heat exchange efficiency.

[0090] In one embodiment, the heater further includes a water inlet assembly 40 and a water outlet assembly 50 , wherein the water inlet assembly 40 is connected to the liquid inlet port of the heating tube 10 , and the water outlet assembly 50 is connected to the liquid outlet port of the heating tube 10 .

At the same time, the annular abutting flange of the water inlet sealing ring 44 can also simultaneously abut against the ends of the water inlet body 41 and the heating tube 10. Afterwards, after the water inlet body 41 is fixed to the end of the heating tube 10, the water inlet sealing ring 44 can be used to achieve sealing between the water inlet body 41 and the heating tube 10.

[0099] Moreover, in order to improve the sealing effect, a plurality of annular sealing flanges can be further provided on the outer periphery of the water inlet sealing ring 44 .

[0102] It can be understood that, as previously described, the center column 22 in this embodiment is detachably arranged inside the heating tube 10. After the center column 22 is placed inside the heating tube 10, the end of the center column 22 can be fixed and positioned with the help of the first positioning plate 45.

It can be understood that the axial direction of the water inlet body 41 is parallel to the axial direction M of the heating tube 10.

[0107] During actual installation, after the center column 22 is placed in the heating tube 10, the first positioning protrusion on the first positioning sheet 45 can be inserted into the first positioning hole of the center column 22, and then the water inlet sealing ring 44 can be abutted against the multiple first extension plates of the first positioning sheet 45, so as to fix the first positioning sheet 45. Moreover, after the fluid enters the water inlet cavity 43 of the water inlet body 41, the fluid can enter the heating cavity 11 through the gaps between the multiple first extension plates.

[0108] Optionally, the first positioning piece 45 and the water inlet sealing ring 44 can be positioned with the help of a slot structure.

The second end of the water outlet body 51 can be connected to the heating pipe 10, and the water outlet chamber 53 is connected to the heating chamber 11.

[0113] As an implementation method, the water outlet body 51 can be fixedly connected to the end of the heating pipe 10 by means of a flange structure.

[0114] In actual use, the first end of the water outlet body 51 can be connected to the water outlet pipe, and the fluid heated in the heating chamber 11 can enter the water outlet chamber 53 and then enter the water outlet pipe through the water outlet 52 to be supplied to the outside.

[0115] In one embodiment, Figure 3 As shown, the water outlet assembly 50 includes: a water outlet sealing ring 54, which is sleeved on the end of the water outlet body 51 facing the heating pipe 10, and the water outlet sealing ring 54 can form a seal between the water outlet body 51 and the heating pipe 10.

[0116] Similarly, the water outlet sealing ring 54 can be made of a high-temperature resistant rubber material, and the second end of the water outlet body 51 can be partially inserted into the heating pipe 10. The water outlet sealing ring 54 is sleeved on the second end of the water outlet body 51, and a radially outwardly extending annular abutment flange is provided on one side of the water outlet sealing ring 54 close to the water outlet 52.

[0117] During installation, the water outlet sealing ring 54 can be partially inserted into the heating tube 10 along with the second end of the water outlet body 51. The water outlet sealing ring 54 can simultaneously abut against the second end of the water outlet body 51 and the inner wall of the heating tube 10. At the same time, the annular abutting flange of the water outlet sealing ring 54 can also simultaneously abut against the ends of the water outlet body 51 and the heating tube 10. Afterwards, after the water outlet body 51 is fixed to the end of the heating tube 10, the water outlet sealing ring 54 can be used to achieve sealing between the water outlet body 51 and the heating tube 10.

[0118] Moreover, in order to improve the sealing effect, a plurality of annular sealing flanges can be further provided on the outer periphery of the water outlet sealing ring 54 . The plurality of annular sealing flanges are arranged at intervals along the axial direction M of the heating tube 10 , and the plurality of annular sealing flanges can all abut against the inner wall of the heating tube 10 .

[0119] Therefore, by providing a plurality of annular sealing flanges on the outer periphery of the water outlet sealing ring 54 , the sealing effect between the heating tube 10 and the water outlet sealing ring 54 can be further improved.

[0120] In one embodiment, Figure 3 As shown, the water outlet assembly 50 includes: a second positioning plate 55, one side of the second positioning plate 55 is connected to the end of the water outlet body 51 facing the heating tube 10, and the other side of the second positioning plate 55 is connected to the end of the center column 22 facing the water outlet assembly 50.

[0121] It can be understood that, as previously described, the center column 22 in this embodiment is detachably arranged inside the heating tube 10. After the center column 22 is placed inside the heating tube 10, the other end of the center column 22 can be fixed and positioned with the help of the second positioning plate 55.

[0122] As an implementation manner, a second positioning hole is provided at the end of the center column 22 facing the water outlet assembly 50 , and the second positioning piece 55 has a second positioning protrusion, which is adapted to be inserted in the second positioning hole.

Afterwards, the second positioning piece 55 can be fixed by utilizing the fixed connection between the water outlet body 51 and the heating tube 10, thereby positioning and fixing one end of the center column 22.

[0124] Therefore, with the help of the water inlet assembly 40 and the water outlet assembly 50, the center column 22 can be positioned and fixed from both ends of the center column 22, so that the center column 22 can be stably installed inside the heating tube 10.

[0125] In a specific embodiment, the second positioning plate 55 may also include a plurality of second extension plates, which are arranged in sequence along the circumference of the second positioning protrusion, one end of the plurality of second extension plates is connected to the second positioning protrusion, and the other end extends outward along the radial direction of the second positioning protrusion.

[0126] A radially inwardly extending abutment ring is provided on the side of the water outlet sealing ring 54 away from the water outlet 52. After the water outlet sealing ring 54 is sleeved onto the second end of the water outlet body 51, the abutment ring on the water outlet sealing ring 54 can abut against the end of the second end in the axial direction of the water outlet body 51. It can be understood that the axial direction of the water outlet body 51 is parallel to the axial direction M of the heating pipe 10.

Moreover, when the fluid in the heating chamber 11 needs to flow out, the fluid can enter the water outlet chamber 53 of the water outlet body 51 through the gaps between the multiple second extension plates and then flow out.

[0128] Optionally, the second positioning piece 55 and the water outlet sealing ring 54 can be positioned with the help of a slot structure. For example, a slot is provided on the side of the water outlet sealing ring 54 facing the second positioning piece 55, and the second positioning piece 55 can be adapted to be snapped into the slot.

[0129] In one embodiment, Figure 3 As shown, the water outlet assembly 50 includes: a water outlet temperature sensor 56 , which is inserted into the water outlet cavity 53 and is used to sense the temperature in the water outlet cavity 53 .

[0130] For example, a mounting hole connected to the water outlet cavity 53 is provided on the side of the water outlet body 51, and the water outlet temperature sensor 56 can be inserted into the water outlet cavity 53 through the mounting hole. Therefore, by providing the water outlet temperature sensor 56 in the water outlet cavity 53, the temperature in the water outlet cavity 53 can be accurately obtained, so as to effectively control the heating temperature.

[0131] In this embodiment, a water dispenser is also provided. Fig. 9 As shown, the water dispenser includes: a water dispenser body and a heater in this embodiment.

[0132] In one embodiment, the water dispenser further comprises a heat storage device, the liquid inlet port of the heat storage device is used to communicate with the water supply system; the liquid inlet port of the heater is communicated with the liquid outlet port of the heat storage device, and the liquid outlet port of the heater can be selectively communicated with the heat storage device and the water outlet;

[0133] When the liquid outlet port of the heater is connected to the heat storage device, the heat storage device uses the hot water output by the heater to store heat.

[0134] like Fig. 9 As shown, the water dispenser includes: a heat storage module 1 and a heater 2; the liquid inlet port of the heat storage module 1 is used to communicate with the water supply system 5; the liquid inlet port of the heater 2 is communicated with the liquid outlet port of the heat storage module 1, and the liquid outlet port of the heater 2 can be selectively communicated with the heat storage module 1 and the water outlet 6;

[0135] When the liquid outlet port of the heater 2 is connected to the heat storage module 1 , the heat storage module 1 uses the hot water output by the heater 2 to store heat.

[0136] It is understandable that the water supply system 5 can be either a water tank or a water purification system, which can stably supply water to the liquid inlet port of the thermal storage module 1 .

[0137] The heat storage module 1 generally includes a heat exchange element and a heat storage material. A heat exchange channel is formed on the inner side of the heat exchange element. The heat storage material is in contact with the outer side of the heat exchange element. The heat storage material may be a solid-liquid phase change material, cast aluminum, water, etc. The water supply system 5 is connected to the heater 2 through the heat exchange channel.

[0138] The liquid outlet port of the heater 2 can be connected to the liquid inlet port of the heat exchange channel or the middle of the heat exchange channel, so as to supply the hot water output by the heater 2 to the heat exchange channel of the heat storage module 1, and then based on the heat exchange of the wall of the heat exchange channel, the thermal energy of the hot water is stored in the phase change material; the temperature of the phase change material rises after the charging is completed, and the temperature in the heat exchange channel can be maintained within a preset range for a certain period of time, thereby preheating the cold water passing through the heat exchange channel.

[0139] In practical applications, before the user takes water, or during the idle time when the user takes water (no water taking operation), the liquid outlet port of the heater 2 can be connected to the thermal storage module 1, so as to use hot water to store heat and charge the thermal storage module 1. The heater 2 can adaptively adjust the heating power according to the outlet water temperature of the water outlet 6.

[0140] As can be seen from the above, the water dispenser can utilize the hot water output by the heater 2 to store heat in the heat storage module 1 by configuring the heat storage module 1 and the heater 2, without the need to use other additional equipment to provide the thermal energy required for the heat storage of the heat storage module 1, which is not only low-cost but also energy-saving and environmentally friendly. After the heat storage module 1 completes heat storage, the heat storage module 1 can be used to preheat the cold water supplied by the water supply system 5, and then the heater 2 can be used to heat the preheated water. This design is conducive to ensuring the water outlet temperature and flow rate of the water outlet 6. The water dispenser can instantly output a large flow of hot water from the water outlet 6, reducing the user's water connection time, thereby realizing a large flow of hot water supply in an energy-saving and efficient manner.

[0141] In some embodiments, Fig. 9 As shown, the water dispenser further includes a valve control 3, and the valve control 3 has a first state and a second state;

[0142] When the valve control 3 is in the first state, the liquid outlet port of the heater 2 is connected to the water outlet 6 through the valve control 3; when the valve control 3 is in the second state, the liquid outlet port of the heater 2 is connected to the heat storage module 1 through the valve control 3 to form a circulating water circuit based on the heat storage module 1 and the heater 2.

[0143] It is understandable that the valve control unit 3 can be a two-position three-way electromagnetic reversing valve, and the water dispenser is equipped with an operation panel and a control module. The operation panel and the control module are electrically connected, and the control module and the valve control unit 3 are electrically connected.

[0144] The operation panel is used to receive a first operation instruction from the user, for example, the first operation instruction may be a water extraction instruction. The control module responds to the first operation instruction and controls the valve control 3 to be in the first state. At this time, the water dispenser operates in the water outlet mode, and the water supplied by the water supply system 5 passes through the heat storage module 1, the heater 2 and the valve control 3 in sequence, and then is output from the water outlet 6. Since the water has been preheated to a certain temperature before entering the heater 2, the difference between the inlet temperature of the heater 2 and the target temperature is reduced, so that the heater 2 can heat a larger flow of water to a high temperature.

[0145] At the same time, the operation panel is used to receive the user's second operation instruction, which may be a power-on instruction or a heat storage instruction. The control module responds to the second operation instruction and controls the valve control 3 to be in the second state. At this time, the water dispenser operates in the heat storage mode, and the heat storage module 1, heater 2 and valve control 3 are connected in sequence to form a circulating water circuit.

[0146] In the process of storing heat in the heat storage module 1, the heater 2 starts to run. When the hot water output by the heater 2 flows through the heat storage module 1, part of the heat of the hot water is transferred to the heat storage material in the heat storage module 1. After the water temperature drops, it flows into the heater 2 for heating, and this cycle is repeated until the water is heated to the target heating temperature.

[0147] The target heating temperature is greater than the phase change temperature of the heat storage material in the heat storage module 1 to ensure the effect of using hot water to store heat and charge the heat storage module 1 .

[0148] In some embodiments, Fig. 9 As shown, the water dispenser further includes a pumping member 4 ; the pumping member 4 is arranged in the circulating water circuit and is used to drive the water to flow through the heat storage module 1 in a directional manner toward the heater 2 .

[0149] It can be understood that the pumping component 4 is a hot water pump, and the pumping component 4 has a flow control function to control the flow rate of the pumped water; when the water dispenser is in the water outlet mode, the pumping component 4 controls the flow rate of the pumped water, the heat storage module 1 ensures the preheating temperature of the water, and the heater 2 further controls the heating power of the water. These three cooperate with each other to ensure the flow rate and temperature of the water output from the water outlet 6.

[0150] At the same time, the pumping component 4 can be arranged on the pipeline between the liquid inlet port of the heat storage module 1 and the liquid outlet port of the heater 2. This design ensures that the pumping component 4 can take into account the pumping requirements of the water body of the water dispenser in the water outlet mode and the heat storage mode. Regardless of whether the water dispenser is in the water outlet mode or the heat storage mode, the water dispenser can work normally.

[0151] In some embodiments, the water dispenser further includes a first trigger, which is connected to the valve control 3; the first trigger is used to receive a water extraction instruction signal, and the valve control 3 is used to switch to the first state according to the signal fed back by the first trigger.

[0152] It is understandable that the first trigger component is electrically connected to the control module, and the control module is electrically connected to the valve control unit 3. The control module controls the working state of the valve control unit 3 according to the trigger instruction fed back by the first trigger component, so that the water dispenser enters the water outlet mode.

[0153] Optionally, the first trigger member may be a water intake button, which may be disposed on an operation panel and used for receiving a pressing instruction from a user.

[0154] Optionally, the first trigger member may be a trigger switch, which is disposed on a water intake valve located at the water outlet 6 and is triggered when a user opens the water intake valve.

[0155] In some embodiments, the water dispenser also includes a second trigger, which is connected to the valve control 3; the second trigger is used to receive a power-on command signal or a heat storage command signal, and the valve control 3 is used to switch to the second state according to the signal feedback from the second trigger.

[0156] It is understandable that the second trigger component is electrically connected to the control module, and the control module is electrically connected to the valve control unit 3. The control module controls the working state of the valve control unit 3 according to the trigger instruction fed back by the second trigger component, so that the water dispenser enters the heat storage mode.

[0157] Optionally, the second trigger may be a power switch, which may be disposed on an operating panel. When the user presses the power switch to power on the water dispenser, the control module may respond to a power-on command signal fed back from the power switch to control the water dispenser to enter a heat storage mode.

[0158] Optionally, the second trigger may be a heat storage button, which may be disposed on the operating panel. When the user presses the heat storage button, the control module may respond to a heat storage command signal fed back from the heat storage button to control the water dispenser to enter the heat storage mode.

[0159] 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 depart 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.
