Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy storage tanks, in particular to a phase change energy storage tank. BACKGROUND

[0002] At present, basically every family installs a water heater (such as an air energy heat pump) to heat the water in the water tank to produce hot water for bathing. When the water tank is replenished with cold water, the water heater needs to heat the water in the water tank again to meet the bathing demand. However, the heater consumes a lot of electricity to heat the water in the water tank, which not only consumes a lot of electricity, but also causes the user to bear a large economic burden due to the high cost of electricity.

[0003] In order to save electricity, a phase change material is generally placed in the water tank to increase the heat preservation time of hot water in the water tank. At present, a steel pipe with a spiral arrangement is connected (usually threaded) to the water tank to place the phase change material in the steel pipe, so that the phase change material in the steel pipe stores energy for the water in the water tank.

[0004] However, placing the phase change material in the water tank by setting the steel pipe in the water tank will result in a large overall weight of the water tank. Since the water tank is closed, the steel pipe is not easy to disassemble from the water tank, making it difficult to transport the water tank, resulting in difficulty in transporting the water tank and a large transportation cost. In addition, it is difficult to remove the phase change material from the steel pipe, so the phase change material in the steel pipe cannot be replaced as needed, resulting in poor flexibility. Moreover, only one type of phase change material with a phase change temperature can be placed in the steel pipe, and the water filled into the water tank will lose heat during the journey, so the temperature of the water entering the water tank cannot reach the phase change temperature of the phase change material in the steel pipe, resulting in the phase change material being unable to store energy.

[0005] Therefore, how to provide a phase change energy storage tank that is convenient to transport and has good flexibility is a technical problem that those skilled in the art need to solve. SUMMARY

[0006] Therefore, the present application provides a phase change energy storage tank to at least solve some of the above technical problems.

[0007] To achieve the above purpose, the present application adopts the following technical solutions:

[0008] A phase change energy storage tank comprises:

[0009] The box body is a closed hollow cavity structure, and the box body is connected with a water inlet pipe and a water outlet pipe respectively, which are in communication with the inner cavity of the box body. The water inlet pipe is connected with a water pump, and the top end of the box body penetrates an installation opening.

[0010] a phase change energy storage component is located in the inner cavity of the box through the installation port, and the density of the phase change energy storage component is equal to the density of water;

[0011] a sealing cover which is detachably connected with the installation port.

[0012] Preferably, the phase change energy storage component comprises:

[0013] a shell which encapsulates a phase change energy storage material in an inner cavity of the shell;

[0014] a counterweight which is connected to the shell, and the density of the counterweight, the shell and the phase change energy storage material is equal to the density of water.

[0015] Preferably, the shell is a hollow strip-shaped tube with a flat end and a round end, and the counterweight is connected to the round end of the shell.

[0016] Preferably, the shell is a hollow cylindrical tube, and the counterweight is connected to any circular face of the shell.

[0017] Preferably, the shell has an opening which is communicated with the inner cavity of the shell, the inner cavity of the shell is filled with the phase change energy storage material through the opening of the shell, the counterweight is connected to the opening end of the shell and blocks the opening of the shell.

[0018] Preferably, the outer surface of the shell is a threaded surface.

[0019] Preferably, an electric water heater is connected to the water inlet pipe.

[0020] Preferably, a plurality of thermistors are connected to the inner wall of the box, and a controller and a display screen are provided outside the box, and the controller is electrically connected to the display screen and the plurality of thermistors respectively.

[0021] Preferably, the box wall comprises, from inside to outside, a polyurea layer, a thermal insulation layer and a metal layer, and the thermal insulation layer is connected to the polyurea layer and the metal layer respectively.

[0022] According to the above technical solution, compared with the prior art, the phase change energy storage bin provided by the present application can achieve the following technical effects:

[0023] The box and the phase change energy storage component of the present application are in a split structure, so when the present application is transported, the phase change energy storage component can not be placed in the box, but the box and the phase change energy storage component are transported separately, which reduces the weight of the box and facilitates transportation.

[0024] The application can improve the uniformity of heat exchange, because the phase change energy storage component can suspend in the water in the tank and move with the fluctuation of the water, so that the temperature stratification of the water in the tank is not easy to occur, and if the water inlet pipe and / or the water outlet pipe are connected to the middle of the side wall of the tank or the bottom end of the tank, the connection of the tank with the water inlet pipe and the water outlet pipe is not easy to be blocked by the phase change energy storage component.

[0025] When the application is used for a period of time, if the user changes the requirement for the energy storage temperature, the sealing cover can be removed from the installation port, then the phase change energy storage components in the tank are poured out with the water through the installation port, and then other phase change energy storage components with different phase change temperatures are put into the tank to meet the current requirement for the phase change energy storage temperature, so that the application has high flexibility in use.

[0026] A plurality of phase change energy storage components with different phase change temperatures can be placed in the tank through the installation port, for example, if the temperature of the water transported into the water inlet pipe is 50 degrees, phase change energy storage components with phase change temperatures of 40 degrees, 41 degrees, 42 degrees, 43 degrees, 44 degrees, 45 degrees, 46 degrees, 47 degrees, 48 degrees, 40 degrees and 50 degrees can be placed in the tank through the installation port, so that even if there is heat loss during the process of transporting 50-degree water into the tank through the water inlet pipe, since the phase change temperatures of the plurality of phase change energy storage components in the tank are in a ladder form, the water entering the tank is easy to meet the phase change temperature of one of the phase change energy storage components, so that the application can realize multi-stage phase change energy storage.

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0032] The embodiment of the present application discloses a phase change energy storage bin, comprising:

[0033] The box body 1 is a closed hollow cavity structure, and the water inlet pipe 2 and the water outlet pipe 3 which are both communicated with the inner cavity of the box body 1 are connected to the box body 1, and a water pump is connected to the water inlet pipe 2, and the top end of the box body 1 penetrates an installation port 10;

[0034] The phase change energy storage component is located in the inner cavity of the box body 1 through the installation port 10, and the density of the phase change energy storage component is equal to the density of water;

[0035] The sealing cover is detachably connected to the installation port 10.

[0036] The box body 1 and the phase change energy storage component of the present application are in a split structure, so that the phase change energy storage component can not be placed in the box body 1 during transportation, but the box body 1 and the phase change energy storage component are transported separately, thereby reducing the weight of the box body 1 and facilitating transportation.

[0037] When it is necessary to place the phase change energy storage component in the inner cavity of the box body 1, the sealing cover is removed from the installation port 10, and then the phase change energy storage component can be placed in the inner cavity of the box body 1 through the installation port 10, and then the sealing cover is placed in the installation port 10, so that the present application can be normally used at this time;

[0038] For example, when the present application is applied in the field of heat storage, the use principle is that the water inlet pipe 2 is connected to the water outlet end of the heater (air energy heat pump), the water outlet end of the radiator is connected to the inlet end of the heater (air energy heat pump), and the water outlet end of the heater (air energy heat pump) is connected to the water inlet end of the heater (air energy heat pump);

[0039] When the heater (air energy heat pump) works and the water pump is turned on at night (night is the low power consumption period, and the electricity fee is cheap), the hot water generated by the heater (air energy heat pump) is pumped into the inner cavity of the box 1 through the water inlet pipe 2 under the pumping action of the water pump, at this time, the phase change material in the phase change energy storage component in the box 1 is converted from solid to liquid to store heat, and since the density of the phase change energy storage component is equal to the density of water, the phase change energy storage component can be suspended in the water in the box 1 and can move with the fluctuation of the water, so that the water in the box 1 is not prone to temperature stratification, and thus the uniformity of heat exchange of the application can be improved; and if the water inlet pipe 2 and / or the water outlet pipe 3 are connected to the middle of the side wall of the box 1 or the bottom end of the box 1, since the phase change energy storage component can be suspended in the water in the box 1 and can move with the fluctuation of the water, the connection of the box 1 with the water inlet pipe 2 and the water outlet pipe 3 is not prone to being blocked by the phase change energy storage component.

[0040] When the hot water in the box 1 flows into the radiator to be used, the cooled water after releasing heat in the radiator is recirculated into the inner cavity of the box 1 through the heater (air energy heat pump) (at this time, the heater (air energy heat pump) is in a non-heating mode), at this time, the phase change energy storage material in the phase change energy storage component is converted from liquid to solid to release heat, so that the water in the box 1 can be heated, and thus the heating time of the heater (air energy heat pump) can be reduced, and the electric energy can be saved.

[0041] When the application is applied in the heat storage field, the phase change energy storage material in each phase change energy storage component is stearic acid, palmitic acid, myristic acid, lauric acid, n-octadecane, chloride salt, nitrate salt, phosphate salt, mirabilite, calcium chloride hexahydrate, magnesium chloride hexahydrate, or disodium hydrogen phosphate dodecahydrate, and the phase change temperature is -60℃-110℃.

[0042] For example, when the application is applied in the cold storage field: a refrigeration device is connected to the inlet of the air conditioner circulating water tank, and a water return pipe is connected between the outlet of the air conditioner circulating water tank and the refrigeration device (the principle of the refrigeration device and the water circulation of the air conditioner is prior art, which will not be described here);

[0043] The phase change energy storage bin of the application can be used as a circulating water tank of an air conditioner refrigeration device, and at night (night is the low power consumption period, and the electricity fee is cheap), cold water is generated by the air conditioner refrigeration device by consuming electric energy (how to generate cold water is prior art, which will not be described here), and the cold water generated by the air conditioner refrigeration device flows into the box 1 through the water inlet pipe under the pumping action of the water pump, at this time, the phase change material in the phase change energy storage component in the box 1 is converted from liquid to solid to store cold;

[0044] When the temperature of the cold water in the box 1 is increased after being used, the used water in the box 1 is returned to the box 1 through the return water pipe and the air conditioning refrigeration equipment (how to return is the prior art, and will not be described here). At this time, the air conditioning refrigeration equipment can be selected not to consume electric energy to prepare cold water, that is, the air conditioning refrigeration equipment is in a non-refrigeration state, and at this time the phase change energy storage material in the phase change energy storage component of the application changes from solid to liquid to release cold energy, thereby refrigerating the water in the box 1.

[0045] When the application is applied in the field of cold storage, the phase change energy storage material in each phase change energy storage component is stearic acid, palmitic acid, myristic acid, lauric acid, n-octadecane, chloride salt, nitrate salt, phosphate salt, mirabilite, calcium chloride hexahydrate, magnesium chloride hexahydrate or disodium phosphate hydrogen phosphate dodecahydrate, and the phase change temperature is -60℃-110℃.

[0046] When the application is used for a period of time, if the user changes the requirement for the energy storage temperature, the sealing cover can be removed from the installation port 10, and then the phase change energy storage components in the box 1 are poured out with the water through the installation port 10, and then other phase change energy storage components with different phase change temperatures are placed in the box 1 to meet the current requirement for the phase change energy storage temperature, so that the application has high flexibility in use.

[0047] The sealing cover can be inserted into the installation port 10, or it can be in other forms, as long as the sealing cover can block the installation port 10 and can be removed from the installation port 10.

[0048] In order to further optimize the above technical solution, the box 1 is connected to a water supplement pipe.

[0049] The application adopts the above technical solution, and when the application is applied in the field of heat storage, one end of the water supplement pipe is connected to a water faucet, the other end is connected to the water inlet end of the heater (air energy heat pump), and the water inlet pipe 2 is connected to the water outlet end of the heater (air energy heat pump), and the water outlet pipe 3 is connected to the shower spray system (the shower spray system is the prior art and has been basically applied in every household, so the structure of the shower spray system will not be described here).

[0050] When the heater (air energy heat pump) works at night (night is the low power consumption period, and the electricity fee is cheap), the water pump is started, and the hot water generated by the heater (air energy heat pump) is pumped into the inner cavity of the box 1 through the water inlet pipe 2, so that the phase change material in the phase change energy storage component in the box 1 is converted from solid to liquid to store heat, and since the density of the phase change energy storage component is equal to the density of water, the phase change energy storage component can be suspended in the water in the box 1 and can move with the fluctuation of the water, so that the water in the box 1 is not prone to temperature stratification, and thus the uniformity of heat exchange of the application can be improved. In addition, if the water inlet pipe 2 and / or the water outlet pipe 3 are connected to the middle part of the side wall of the box 1 or the bottom end of the box 1, since the phase change energy storage component can be suspended in the water in the box 1 and can move with the fluctuation of the water, the connection of the box 1 with the water inlet pipe 2 and the water outlet pipe 3 is not prone to being blocked by the phase change energy storage component.

[0051] The hot water in the box 1 can flow into the shower spray system for use, the faucet can be started, and the cold water flowing out of the faucet can flow into the box 1 through the water supplement pipe and the heater (air energy heat pump) in turn, at this time, the phase change energy storage material in the phase change energy storage component is converted from liquid to solid to release heat, so that the water in the box 1 can be heated, and thus the heating time of the heater (air energy heat pump) can be reduced, and the electric energy can be saved.

[0052] In order to further optimize the above technical solution, the water supplement pipe, the water inlet pipe 2 and the water outlet pipe 3 are all connected to the top end of the box 1.

[0053] The application adopts the above technical solution, and since the water pump pumps water into the box 1, the pressure in the box 1 increases, and the water supplement pipe, the water inlet pipe 2 and the water outlet pipe 3 are all connected to the top end of the box 1, so that the water in the box 1 is not prone to leaking from the interfaces of the box 1 with the water supplement pipe, the water inlet pipe 2 and the water outlet pipe 3 under the action of the pressure in the box 1.

[0054] In order to further optimize the above technical solution, the phase change energy storage component is multiple, and the multiple phase change energy storage components are all located in the inner cavity of the box 1 through the mounting port 10, and the density of each phase change energy storage component is equal to the density of water.

[0055] The application adopts the technical scheme, and multiple phase change energy storage components with different phase change temperatures can be placed in the box 1 through the installation opening 10. For example, if the temperature of the water delivered to the water inlet pipe 2 is 50 degrees, phase change energy storage components with phase change temperatures of 40 degrees, 41 degrees, 42 degrees, 43 degrees, 44 degrees, 45 degrees, 46 degrees, 47 degrees, 48 degrees, 40 degrees and 50 degrees can be placed in the box 1 through the installation opening 10. Even if the water with a temperature of 50 degrees is delivered to the box 1 through the water inlet pipe 2 and heat is lost in the process, since the phase change temperatures of the multiple phase change energy storage components in the box 1 are in a ladder shape, the water entering the box 1 can easily meet the phase change temperature of one of the phase change energy storage components, so that the application can realize multi-stage phase change energy storage.

[0056] In order to further optimize the above technical scheme, the phase change energy storage component comprises:

[0057] The shell 41 has an inner cavity in which the phase change energy storage material is encapsulated;

[0058] The counterweight 42 is connected to the shell 41, and the densities of the counterweight 42, the shell 41 and the phase change energy storage material are equal to the density of water.

[0059] The application adopts the above technical scheme. Since the densities of the counterweight 42, the shell 41 and the phase change energy storage material are equal to the density of water, when the phase change energy storage component is placed in the box 1, the phase change energy storage component can be suspended in the water and move with the fluctuation of the water, so that: on the one hand, since the phase change energy storage component does not sink, if any one of the water inlet pipe 2, the water outlet pipe 3 and the water supplement pipe is connected to the middle of the side wall of the box 1 or the bottom end of the box 1, the phase change energy storage component is not easy to block the connection of the box 1 (a container for placing the phase change energy storage component and water) and the water inlet pipe 2, the water outlet pipe 3 and the water supplement pipe; on the other hand, since the phase change energy storage component can move with the fluctuation of the water, the water in the box 1 is not easy to have temperature stratification, so that the uniformity of heat exchange can be improved.

[0060] In addition, the phase change energy storage component can be applied in the field of heat storage and cold storage. The corresponding energy can be stored during the low electricity consumption period, and the corresponding energy can be released during the high electricity consumption period, so that the energy saving purpose of "peak load shifting" can be achieved, and the electricity cost can be saved.

[0061] Moreover, if the phase change energy storage component is not placed in the water, since the specific heat capacity of water is 4.2 x 10 3The water has a low energy storage density, and thus a large water pool is generally required to meet the energy storage requirement. However, when the phase change energy storage component is placed in the water, the specific heat capacity of the phase change energy storage material (stearic acid, palmitic acid, myristic acid, lauric acid, n-octadecane, chloride salt, nitrate salt, phosphate salt, mirabilite, calcium chloride hexahydrate, magnesium chloride hexahydrate, and disodium hydrogen phosphate dodecahydrate) in the phase change temperature range (-60°C-110°C) can reach 220-240 J / (kg·℃), and thus the overall structure formed by mixing has a large specific heat capacity, and thus the overall energy storage density is improved.

[0062] When the application is applied in the heat storage field, the phase change energy storage material in each shell 41 is stearic acid, palmitic acid, myristic acid, lauric acid, n-octadecane, chloride salt, nitrate salt, phosphate salt, mirabilite, calcium chloride hexahydrate, magnesium chloride hexahydrate, or disodium hydrogen phosphate dodecahydrate, and the phase change temperature is -60°C-110°C. When the application is applied in the cold storage field, the phase change energy storage material in each shell 41 is stearic acid, palmitic acid, myristic acid, lauric acid, n-octadecane, chloride salt, nitrate salt, phosphate salt, mirabilite, calcium chloride hexahydrate, magnesium chloride hexahydrate, or disodium hydrogen phosphate dodecahydrate, and the phase change temperature is -60°C-110°C.

[0063] To further optimize the above technical solution, the shell 41 is a hollow cylindrical tube with one end being flat and the other end being round, and the counterweight 42 is connected to the round end of the shell 41.

[0064] In the embodiment, the shape of the shell 41 is similar to the shape of a common toothpaste shell in life.

[0065] When the phase change energy storage component is suspended in water, the end of the shell 41 connected to the counterweight 42 faces downward, and the flat end faces upward, so that the multiple phase change energy storage components are not easily crowded and stacked after being placed in the water, that is, a large space can be provided between each two adjacent shells 41 to facilitate water flow, thereby ensuring a high heat exchange efficiency.

[0066] To further optimize the above technical solution, the shell 41 is a hollow cylindrical tube, and the counterweight 42 is connected to any circular face of the shell 41.

[0067] The above technical solution is adopted, and more phase change energy storage materials can be filled in the shell 41, thereby having a stronger energy storage capacity.

[0068] In order to further optimize the above technical solution, the shell 41 has an opening communicating with the inner cavity of the shell 41, and the inner cavity of the shell 41 is filled with a phase change energy storage material through the opening of the shell 41, and the counterweight 42 is connected to the opening end of the shell 41 and blocks the opening of the shell 41.

[0069] When the shell 41 is a hollow strip-shaped tube with one flat end and the other round end, the opening is located at the round end of the shell 41; when the shell 41 is a hollow cylindrical tube, the opening is located at the round face end connected with the counterweight 42.

[0070] The application adopts the above technical solution, and the phase change energy storage material can be filled into the cavity of the shell 41 through the opening of the shell 41, and the counterweight 42 not only has the effect of counterweight, but also has the effect of blocking the opening of the shell 41.

[0071] In order to further optimize the above technical solution, the outer surface of the shell 411 is a threaded surface.

[0072] The application adopts the above technical solution, and the threaded surface can increase the heat exchange surface area of the shell 411, thereby improving the efficiency of heat exchange.

[0073] In order to further optimize the above technical solution, the water inlet pipe 2 is connected with an electric water heater 21.

[0074] The electric water heater 21 is a prior art, and can be an instant water heater.

[0075] The application adopts the above technical solution, and the temperature sensor in the instant water heater can monitor the temperature of the water in the water inlet pipe 2. When the water temperature decreases due to heat loss during transmission, the actual temperature of the water in the water inlet pipe 2 will be monitored by the temperature sensor in the instant water heater and transmitted to the control circuit in the instant water heater. The control circuit in the instant water heater can control the heating module of the instant water heater to start, and when the heating module in the instant water heater heats the water in the water inlet pipe 2 to the preset temperature threshold in the control circuit of the instant water heater, the heating module in the instant water heater will automatically stop heating. Therefore, as long as the temperature threshold in the control circuit of the instant water heater is set to the phase change temperature of the phase change energy storage component, the phase change energy storage component in the box body 1 can be ensured to store energy.

[0076] In order to further optimize the above technical solution, the inner wall of the box body 1 is connected with a plurality of thermistors, and the box body 1 has a controller 6 and a display screen 8 outside, and the controller 6 is electrically connected with the display screen 8 and the plurality of thermistors respectively.

[0077] The application adopts the technical scheme, the temperature information of the water in the box 1 can be monitored by the thermistor, and the monitored temperature information is transmitted to the controller 6, then the controller 6 can analyze the temperature information transmitted by the thermistor (according to the program programmed in the controller 6, for example, the controller 6 can analyze the current water temperature in the box 1 according to the temperature information transmitted by the thermistor, and how much energy can be stored), and the analysis result can be sent to the display screen, so that the result analyzed by the controller 6 can be displayed on the display screen 8, so that the temperature information in the box 1 can be known by the staff, and adaptive work can be done.

[0078] In addition, the inner wall of the box 1 of the application is connected with a plurality of thermistors, and the plurality of thermistors can be respectively arranged at different positions of the inner wall of the box 1, so that the accuracy of the temperature in the box 1 can be improved.

[0079] In order to further optimize the above technical scheme, the box wall of the box 1 comprises a polyurea layer, a heat insulation layer and a metal layer arranged in sequence from inside to outside, and the heat insulation layer is connected with the polyurea layer and the metal layer respectively.

[0080] The application adopts the above technical scheme, the box wall of the box 1 is arranged with a polyurea layer, a heat insulation layer and a metal layer in sequence from inside to outside (from the direction close to the inner cavity of the box 1 to the direction away from the inner cavity of the box 1), so that the box 1 of the application has good water leakage prevention and good heat preservation performance due to the polyurea layer, and the polyurea layer cooperates with the heat insulation layer and the metal layer respectively, so that the water leakage prevention and heat preservation performance of the box 1 can be further improved.

[0081] In the application, the electromagnetic valve is connected to the faucet, and the electromagnetic valve and the water pump are electrically connected with the controller 6, and when the application is applied in the heat storage field, the controller 6 is also electrically connected with the control system of the heating device (such as air energy heat pump) (how the controller 6 is electrically connected with the control system of the heating device (such as air energy heat pump) is known to those skilled in the art, and will not be described here), so that the controller 6 can analyze the temperature information transmitted by the thermistor, and can correspondingly control the electromagnetic valve, the water pump and the heating device (such as air energy heat pump), so as to realize automatic control; when the application is applied in the cold storage field, the controller 6 is electrically connected with the refrigeration device (such as air conditioning refrigeration device), and the controller 6 is not electrically connected with the heating device (such as air energy heat pump), but is electrically connected with the refrigeration device (air conditioning refrigeration device) (the electrical connection between the controller 6 and the refrigeration device (air conditioning refrigeration device) is known to those skilled in the art, and will not be described here), so as to realize automatic control.

[0082] The controller 6 is the control unit of the whole device, which is a prior art and uses PLC for control inside, and the PLC is a prior art, which can be programmed by those skilled in the art according to actual needs, so as to realize the control function described in the embodiment.

[0083] In order to further optimize the above technical solution, the top end of the box body 1 is connected with a plurality of surrounding plates 5 along the circumference of the box body 1, and each adjacent two surrounding plates 5 are connected to define a storage chamber 50 with an open top end through the plurality of surrounding plates 5 and the top end of the box body 1, and a plurality of through holes are respectively formed in any one of the surrounding plates 5.

[0084] The application adopts the above technical solution, so that the controller 6, the water pump and the electric water heater 21 are all placed in the storage chamber 50, thereby the controller 6, the water pump and the electric water heater 21 can be protected through the storage chamber 50, and the water inlet pipe 2 and the water outlet pipe 2 can be led out from the through holes to be connected to the corresponding external equipment, and when the water supplement pipe is connected to the box body 1, the water supplement pipe is also led out from the through hole to be connected to the faucet.

[0085] In order to further optimize the above technical solution, the application further comprises a cover plate 7, which is arranged on the open top end of the storage chamber 50 and detachably connected with the plurality of surrounding plates 5.

[0086] The detachable connection between the cover plate 7 and the plurality of surrounding plates 5 can be achieved by screwing, or a plurality of clamping grooves corresponding to the top ends of the plurality of surrounding plates 5 are formed on the side of the cover plate 7 close to the storage chamber 50, so that the plurality of clamping grooves are clamped with the top ends of the plurality of surrounding plates 5 one by one, or other ways can be used as long as the cover plate 7 can be detachably connected with the plurality of surrounding plates 5.

[0087] The application adopts the above technical solution, which not only can be arranged on the open top end of the storage chamber 50 through the cover plate 7 to provide better protection for the controller 6, the water pump and the electric water heater 21, but also can make the overall structure of the application more tidy, thereby further facilitating transportation.
