Description

Technical Field

[0001] The utility model relates to a water purifier, in particular to an integrated water purification and heating machine. Background Art

[0002] Commercial integrated water purification and heating machines are becoming more and more popular. Currently, most commercial integrated water purification and heating machines on the market generally use a hot water storage tank. However, there are two problems with the water tanks used in the current industry. The first problem is that no matter how good the heat insulation material is, there will be heat loss, and the current heat insulation material has a relatively large heat loss. The second problem is that the electric heaters used are generally tubular, and the contact area with water is limited. Not only is the heating effect poor, but also the water near the heating element has been heated to the set temperature, while the hot water a little farther away from the heater is still warm water, resulting in uneven heating. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the defects of large heat loss of the heat insulation material and uneven electric heating in the integrated water purification and heating machine in the prior art, and provide an integrated water purification and heating machine.

[0004] The utility model solves the above technical problem through the following technical solutions:

[0005] An integrated water purification and heating machine includes a box body, and the interior of the box body is a hot water tank. Its characteristic lies in that it further includes:

[0006] A heating plate, the heating plate is arranged in the hot water tank, and the cross-section of the heating plate along its length direction is in a zigzag shape;

[0007] A heat insulation shell, the heat insulation shell covers the box body, and the heat insulation shell includes a phase change material layer, and the phase change material layer is arranged on the outer side of the heat insulation shell.

[0008] In this solution, adopting the above structure, the heating plate is in a plate shape, which can make its contact area with the hot water in the hot water tank larger. At the same time, the heating plate has a bending structure, which can further increase the heating area and make the heating more uniform. In addition, the outermost layer of the heat insulation shell is a phase change material layer, which uses a phase change material. This material has a large energy storage density and almost constant temperature. It can continue to absorb the remaining heat that penetrates out, and when the temperature of the water tank becomes lower, it can directly release the heat to make up for the heat loss. The above structure can effectively improve the heating efficiency of the hot water tank and reduce the heat loss of the hot water, so as to achieve the purpose of energy conservation.

[0009] Preferably, the heat insulation shell further includes a reflection layer, and the reflection layer is arranged on the inner side of the heat insulation shell.

[0010] In this solution, adopting the above structure, the reflection layer is arranged on the side closest to the hot water tank, which is convenient for effectively reducing heat radiation and reducing heat loss.

[0011] Preferably, the heat insulation shell further includes a heat insulation layer, and the heat insulation layer is disposed between the phase change material layer and the reflective layer.

[0012] In this solution, with the above structure, the heat insulation layer is disposed between the reflective layer and the phase change material layer, which can isolate the thermal radiation that the reflective layer fails to reflect and reduce the internal and external heat exchange.

[0013] Preferably, the heating plate further includes two power terminals, and the two power terminals are disposed on two relatively close sides of the heating plate, and the two power terminals penetrate out of the box body.

[0014] In this solution, with the above structure, arranging the power terminals on the shorter sides is convenient for layout and installation.

[0018] Preferably, the power terminal further includes a limiting plate, the limiting plate is disposed at the end of the threaded portion close to the heating plate, and a sealing ring is disposed between the limiting plate and the box body.

[0019] In this solution, with the above structure, the limiting plate is disposed at the end of the threaded portion and is located inside the hot water tank, and a sealing ring is further disposed between it and the inner wall of the tank. When the heating plate is fixed, the tightening of the threaded portion and the fixing nut will cause the limiting portion to move towards the inner wall of the tank and compress the sealing ring, improving the sealing effect while fixing.

[0020] Preferably, the heating plate is disposed at the bottom of the hot water tank.

[0021] In this solution, with the above structure, disposing the heating plate at the bottom of the hot water tank can ensure that the water in the hot water tank can contact the heating plate and be heated normally in any state.

[0022] Preferably, the heating plate is arranged horizontally.

[0023] In this solution, with the above structure, the overall height is reduced, and the contact area with water can be ensured even at low water levels, thereby increasing the heating efficiency.

[0024] Preferably, a blind hole leading to the box body is further provided on the heat insulation shell, and a temperature sensor is disposed in the blind hole.

[0025] In this solution, adopting the above structure facilitates the detection of the hot water temperature in the hot water tank, and setting it outside can also avoid the problem of liquid tightness.

[0026] Preferably, it further includes an impeller, a motor, and a drive shaft. The motor is arranged outside the box body, the motor is connected to the impeller inside the box body through the drive shaft, and the impeller is arranged at one end of the hot water tank close to the heating plate.

[0027] In this solution, adopting the above structure, when the heating plate heats up, the motor controls the impeller to rotate, which can make the cold and hot water in the water tank mix more evenly, and there will be no phenomenon of heating dead spots.

[0028] Preferably, the heating plate includes a stainless steel outer shell, a heating body is included inside the stainless steel outer shell, and an insulating layer is further arranged between the heating body and the stainless steel outer shell.

[0029] In this solution, adopting the above structure, the heating effect of the heating plate is better and the safety is higher.

The interior of the box body is a hot water tank 101, and it further includes a heating plate 110 and a heat preservation shell 200. The heating plate 110 is arranged in the hot water tank 101, and the cross-section of the heating plate 110 along its length direction is in a broken line shape. The heat preservation shell 200 covers the box body, and the heat preservation shell 200 includes a phase change material layer 201, and the phase change material layer 201 is arranged on the outer side of the heat preservation shell 200. Among them, Figure 2 Cross-sectional view of the combined water and heat purification machine of this embodiment. Figure 3 Cross-sectional view of the box body after removing the heat preservation shell 200 in this embodiment.

[0071] In this embodiment, the heat preservation shell 200 includes at least one layer of phase change material layer 201, and the phase change material layer 201 covers the outside of the entire combined water and heat purification machine. The heat preservation shell 200 is in the shape of an outer shell and completely covers the outside of the box body of the combined water and heat purification machine. The heating plate 110 Figure 5 and Figure 8 shown, the heating plate 110 includes a stainless steel outer shell, and a heating body is included inside the stainless steel outer shell. An insulating layer is also arranged between the heating body and the stainless steel outer shell. The stainless steel outer shell, the heating body and the insulating layer are all in the shape of a bent broken line plate. The phase change material layer 201 of this embodiment can adopt inorganic PCM, organic PCM, composite PCM, FTC self-regulating temperature phase change energy-saving material or other conventional phase change materials in the prior art.

[0072] The heating plate 110 is in a plate shape, which can make the contact area with the hot water in the hot water tank 101 larger. At the same time, the heating plate 110 has a bent structure, which can further increase the heating area and make the heating more uniform. In addition, the outermost layer of the heat preservation shell 200 is the phase change material layer 201, and this layer uses a phase change material, which has a large energy storage density and almost constant temperature. It can continue to absorb the remaining heat that penetrates out, and when the temperature of the water tank becomes lower, it can directly release the heat to make up for the heat loss. The above structure can effectively improve the heating efficiency of the hot water tank 101 and reduce the heat loss of the hot water, so as to achieve the purpose of energy saving.

[0073] The cabinet of the integrated net heat machine in this embodiment is rectangular, and the interior is a hot water tank 101 for heating and containing hot water. A sewage outlet 104, a water inlet 105 and an exhaust outlet 103 are provided at the bottom thereof. Among them, the exhaust outlet 103 is connected to an exhaust pipe, and the exhaust pipe extends from the exhaust port to the top of the hot water tank 101 to facilitate the discharge of gas. The water inlet 105 and the sewage outlet 104 are provided at the bottom of the hot water tank 101. The water outlet 106 is provided on the cabinet wall of the cabinet to facilitate water intake and ensure the water intake quality. At the top of the hot water tank 101, a low water level sensor 131, a middle water level sensor 132 and a high water level sensor 133 are respectively provided. The top of the cabinet has a detachable cover plate 120, and a seal 121 is also provided between the cover plate 120 and other parts of the cabinet. The low water level sensor 131, the middle water level sensor 132 and the high water level sensor 133 are provided on the cover plate 120. The surface of the heat preservation shell 200 has a fixing bracket 300 for fixing.

[0074] As Figure 7 shown, the heat preservation shell 200 further includes a reflective layer 203, and the reflective layer 203 is provided on the inner side of the heat preservation shell 200. In this embodiment, the reflective layer 203 is made of aluminum foil paper, and the aluminum foil paper can effectively reduce heat radiation and reduce heat loss. The reflective layer 203 is arranged on the side closest to the hot water tank 101 to effectively reduce heat radiation and reduce heat loss. In other embodiments, other high-reflection materials, such as mirror materials, can also be selected.

[0075] As Figure 7 shown, the heat preservation shell 200 further includes a heat insulation layer 202, and the heat insulation layer 202 is provided between the phase change material layer 201 and the reflective layer 203. In this embodiment, the heat insulation layer 202 is made of polyurethane heat preservation material, which has good heat preservation effect, low heat loss, corrosion prevention, good insulation performance and long service life. The heat insulation layer 202 is arranged between the reflective layer 203 and the phase change material layer 201, and can isolate the heat radiation not reflected by the reflective layer 203 and reduce the internal and external heat exchange.

[0076] As Figure 5 、 Figure 6 shown, the heating plate 110 further includes two power terminals 111, and the two power terminals 111 are arranged on two relatively close sides of the heating plate 110, and the two power terminals 111 pass through the cabinet. In this embodiment, the power terminals 111 are arranged in the middle of the two long sides of the heating plate 110 and pass through the front and back of the cabinet, so that the lengths of both ends of the power supply are shorter. The power terminals 111 are arranged on the shorter sides to facilitate layout and installation.

[0077] As Figure 4 、 Figure 6As shown, the power supply terminal 111 includes a threaded portion 112 that passes through the box body. An installation hole 210 is provided on the heat preservation shell 200, and a fixing nut 211 is provided in the installation hole 210. The fixing nut 211 is fixed to the threaded portion 112. The threaded portion 112 of the power supply terminal 111 is used to be connected and fixed to the fixing nut 211 outside the box body after passing through the box body. While electrically connecting the heating plate 110, it can also play a role in fixing the heating plate 110, making the structure more compact.

[0078] As Figure 4 shown, the power supply terminal 111 further includes a limiting plate 113. The limiting plate 113 is arranged at the end of the threaded portion 112 close to the heating plate 110. A sealing ring is arranged between the limiting plate 113 and the box body. The limiting plate 113 is arranged at the end of the threaded portion 112 and is located inside the hot water tank 101. A sealing ring is also arranged between it and the inner wall of the box body. When the heating plate 110 is fixed, the tightening of the threaded portion 112 and the fixing nut 211 will cause the limiting portion to move towards the inner wall of the box body and press the sealing ring, improving the sealing effect while fixing.

[0079] As Figure 2 shown, the heating plate 110 is arranged at the bottom of the hot water tank 101. Arranging the heating plate 110 at the bottom of the hot water tank 101 can ensure that the water in the hot water tank 101 can contact the heating plate 110 and be heated normally in any state. The heating plate 110 is arranged horizontally, reducing the overall height and ensuring the contact area with water even at a low water level, thereby increasing the heating efficiency.

[0080] As Figure 1 shown, a blind hole 220 leading to the box body is also provided on the heat preservation shell 200, and a temperature sensor 102 is arranged in the blind hole 220. In this embodiment, the temperature sensor 102 further includes a collection part located inside the box body in the hot water tank 101. The collection part can contact the hot water and conduct heat transfer. It is convenient to detect the temperature of the hot water in the hot water tank 101, and arranging it outside can also avoid the problem of liquid tightness.

[0081] Embodiment 2

[0082] This embodiment is generally the same as the structure of the embodiment, and the difference is that, as Figure 9As shown in the figure, the integrated net heat machine of this embodiment further includes an impeller 403, a motor 401, and a drive shaft 402. The motor 401 is arranged outside the box body. The motor 401 is connected to the impeller 403 inside the box body through the drive shaft 402. The impeller 403 is arranged at one end of the hot water tank close to the heating plate 110. In this embodiment, the motor 401 is arranged on the top of the cover plate 120, and the motor 401 can rotate forward and backward. One end of the drive shaft 402 is connected to the motor 401, and the other end is connected to the impeller 403. There are grooves for installing limit pieces and grooves for pin installation at the other end of the drive shaft 402. For the impeller 403, the impeller 403 is limited by a pin to the drive shaft 402 to generate torque and drive the impeller 403 to rotate together. When the heating plate 110 heats up, the motor 401 controls the impeller 403 to rotate, which can make the cold and hot water in the water tank mix more evenly and prevent the phenomenon of heating dead spots. In this embodiment, the motor is arranged on the cover plate 120 for easy disassembly, while the impeller 403 is arranged close to the heating plate 110 to facilitate the rapid mixing of the hot water near the heating plate 110 with the cold water in other parts.
