Referring to fig. 1-7, embodiments of the present disclosure provide a water heating system, comprising: electrically heated water tank 100, first outlet pipe 200, and water pump 300. The first water outlet pipe 200 is communicated with the electric heating water tank 100, and the communication position is positioned in the upper area of the electric heating water tank 100; the lower end of the water pump 300 is communicated with a second water outlet pipe 400, and the water inlet end of the water pump 300 is communicated with the first water outlet pipe 200, so that the water pump 300 is communicated with the electric heating water tank 100.

By adopting the water heating system provided by the embodiment of the disclosure, water in the electric heating water tank 100 is discharged through the first water outlet pipe 200, and water in the water pump 300 is discharged through the second water outlet pipe 400, and as the communication position of the first water outlet pipe 200 and the electric heating water tank 100 is positioned in the upper area, the water storage state in the electric heating water tank 100 is always kept, and the risk of dry burning of the electric heating water tank 100 is reduced. When the water heating system is in a non-working state, the residual stored water in the water pump 300 can be discharged from the second water outlet pipe 400 at the lower end of the water pump 300, so that the corrosion of the stored water to the internal parts of the water pump 300 is reduced, and the service life of the water pump 300 is prolonged. In the hot water system, the structure of the hot water system can be simplified and the cost can be reduced while the risk of dry heating of the electric heating water tank 100 is reduced only by changing the arrangement of the electric heating water tank 100 and the water pump 300.

Optionally, the hot water system further comprises: a first inlet pipe 500. The first water inlet pipe 500 communicates with the electric heating water tank 100, and the communication position is located in a lower region of the electric heating water tank 100. In this way, the water source is injected into the electric heating water tank 100 through the first water inlet pipe 500, the communication position between the first water inlet pipe 500 and the electric heating water tank 100 is set in the lower area of the electric heating water tank 100, so that the injected water source flows through the electric heating water tank 100 from bottom to top, is heated by the electric heating water tank 100 more fully, and improves the heating effect.

Optionally, the water pump 300 includes: the pump body, the water inlet end and the water outlet end. The water inlet end is positioned at the upper end of the pump body, the water outlet end is positioned at the lower end of the pump body, and the second water outlet pipe 400 is communicated with the water outlet end. The water pump 300 is divided into a pump body, a water inlet end, and a water outlet end, and negative pressure generated in the pump body sucks hot water in the electric heating water tank 100 from the first water outlet pipe 200 through the water inlet end and discharges through the water outlet end for a user. The water outlet end is arranged at the lower end of the pump body, when the water heating system is in a non-working state, stored water in the pump body can be discharged to the second water outlet pipe 400 through the water outlet end and discharged through the second water outlet pipe 400, and the condition that the interior of the pump body is corroded by the stored water is relieved.

Specifically, the hot water system further comprises: a second inlet pipe 600. The water inlet end of the water pump 300 communicates with the first water outlet pipe 200 through the second water inlet pipe 600. Thus, the hot water in the electric heating water tank 100 flows out from the first water outlet pipe 200 into the second water inlet pipe 600, and then flows into the pump body through the second water inlet pipe 600. The second water inlet pipe 600 is provided to facilitate the communication between the water pump 300 and the electric heating water tank 100, so that the two can be reasonably arranged.

Optionally, the hot water system further comprises: a housing 700. The housing 700 defines an installation space inside, and the water pump 300, the electric heating water tank 100, the first water outlet pipe 200, the second water outlet pipe 400, the first water inlet pipe 500, and the second water inlet pipe 600 are all disposed in the installation space. In this way, the water pump 300, the electric heating water tank 100, the first water outlet pipe 200, the second water outlet pipe 400, the first water inlet pipe 500 and the second water inlet pipe 600 of the hot water system are integrally installed inside the housing 700 by providing the housing 700, thereby facilitating the installation and use of the hot water system.

Specifically, the water inlet side end portion of the first water inlet pipe 500 protrudes from the side wall of the housing 700, and the water outlet side end portion of the second water outlet pipe 400 protrudes from the side wall of the housing 700. In this way, in order to smoothly communicate an external water source with the first water inlet pipe 500, the hot water outputted from the second water outlet pipe 400 can be smoothly supplied to the outside, the end of the first water inlet pipe 500 is protruded from the side wall of the housing 700, and the end of the second water outlet pipe 400 is protruded from the side wall of the housing 700, so that the external water source can smoothly flow into the electric heating water tank 100 to supplement the water source, and the heated hot water can also be smoothly supplied to the outside through the second water outlet pipe 400.

Alternatively, as shown in fig. 2, the electrically heated water tank 100 includes: a case 110 and a heating part 120. The tank body 110 is communicated with the first water outlet pipe 200, and the communication position of the first water outlet pipe 200 and the tank body 110 is positioned in the upper area of the side wall of the tank body 110; the heating part 120 is provided in the tank 110, and heats water in the tank 110. In this way, the water source replenished from the outside is stored in the tank 110, the water stored in the tank 110 is heated by the heating unit 120 in the tank 110 to form hot water, and the hot water in the tank 110 flows out to the outside through the first water outlet pipe 200 for use. The first water outlet pipe 200 is communicated with the upper area of the side wall of the box body 110, so that excessive hot water in the box body 110 is prevented from flowing out of the first water outlet pipe 200, relatively more water is always stored in the box body 110, and the risk of dry burning of the heating part 120 is reduced.

Alternatively, the communication position of the first water inlet pipe 500 with the tank 110 is located at a lower region of the sidewall of the tank 110. In this way, since the tank 110 is used for storing water, the heating portion 120 is disposed in the tank 110 to heat the stored water, so that the first water inlet pipe 500 is communicated with the lower region of the sidewall of the tank 110, so that the water flowing in through the first water inlet pipe 500 can circulate inside the tank 110 from bottom to top, and more fully contacts the heating portion 120 in the tank 110 to exchange heat, thereby improving the heating efficiency.

Specifically, the heating part 120 is vertically disposed inside the case 110. In this way, water flowing from bottom to top can be sufficiently brought into contact with the heating portion 120, and the heating efficiency of the heating portion 120 can be further improved.

Specifically, the heating part 120 is composed of a plurality of electrothermal tubes, which are spirally wound together. In this way, the heating efficiency of the electrothermal tube is higher, the cost is lower, the heating part 120 is composed of a plurality of spirally wound electrothermal tubes, and the heating efficiency of the heating part 120 is further improved.

Alternatively, the difference in height between the position of communication of the first water outlet pipe 200 with the electric heating water tank 100 and the bottom of the electric heating water tank 100 in the vertical direction is greater than or equal to two thirds of the height of the electric heating water tank 100. In this way, since the hot water in the electric heating water tank 100 is discharged through the first water outlet pipe 200, the communication position between the first water outlet pipe 200 and the electric heating water tank 100 is set at the position which is two thirds of the height of the electric heating water tank 100 from the bottom of the electric heating water tank 100, so that relatively more water is always stored in the electric heating water tank 100, and the risk of dry burning of the electric heating water tank 100 is further reduced.

Specifically, the difference between the height of the bottom of the electric heating water tank 100 and the position of the first water outlet pipe 200 in communication with the electric heating water tank 100 is equal to two thirds of the height of the electric heating water tank 100.

Specifically, the communication position between the first water outlet pipe 200 and the tank 110 is located at two thirds of the height of the tank 110. Thus, since the electric heating water tank 100 is composed of the tank body 110 and the heating part 120, the first water outlet pipe 200 is communicated with the position of two thirds of the height of the tank body 110, so that the tank body 110 can always store relatively more water.

It will be appreciated that the height of the electric heating water tank 100 is the height of the case 110, and the height of the case 110 refers to the distance from the bottom to the top of the case 110 in the vertical direction.

Alternatively, the upper end of the heating part 120 is lower than a position where the first water outlet pipe 200 communicates with the tank 110 in the vertical direction. Thus, the heating part 120 can be immersed by the water in the box 110, and the risk of dry burning of the heating part 120 is further reduced.

Alternatively, a height difference between the upper end of the heating part 120 and a position where the first water outlet pipe 200 communicates with the tank 110 in the vertical direction is greater than 0 and less than or equal to 10 mm. In this way, in the case where the height difference between the upper end of the heating part 120 and the position where the first water outlet pipe 200 and the tank 110 communicate is equal to 0, the upper end of the heating part 120 may be flush with or protrude from the liquid level in the tank 110 at this time, resulting in a partial dry combustion of the heating part 120. In the case where the difference in height between the upper end of the heating part 120 and the position where the first water outlet pipe 200 and the tank 110 communicate is greater than 10 mm, the height of the heating part 120 is relatively small at this time, and the heating efficiency may be affected. Therefore, the height difference between the upper end of the heating part 120 and the position where the first water outlet pipe 200 is communicated with the tank 110 is set to be greater than 0 and less than or equal to 10 mm, which can not only avoid the phenomenon that the upper end of the heating part 120 is flush with or protrudes from the liquid level in the tank 110, but also ensure the heating efficiency of the heating part 120.

Specifically, the difference in height between the upper end of the heating part 120 and the position where the first water outlet pipe 200 and the tank 110 communicate is equal to 5 mm.

Alternatively, the case 110 has a rectangular structure. Thus, the installation of the tank 110 and the setting of electric heating are facilitated, and the water storage capacity of the tank 110 is improved.

In some embodiments, as shown in fig. 1 and 3, the hot water system further comprises: plate heat exchanger 800. A water flow passage 810 and a refrigerant flow passage 820 are arranged in the plate heat exchanger 800, and the water flow passage 810 is adjacent to the refrigerant flow passage 820; wherein, one end of the water channel 810 is communicated with the first water outlet pipe 200, the other end is communicated with the water inlet end of the water pump 300, one end of the refrigerant channel 820 is communicated with the gaseous refrigerant pipe 830, and the other end is communicated with the liquid refrigerant pipe 840. In this way, water flowing out of the electric heating water tank 100 flows into the water channel 810 in the plate heat exchanger 800, high-temperature and high-pressure gaseous refrigerant in the refrigerating system flows into the refrigerant channel 820 in the plate heat exchanger 800, the water in the water channel 810 and the refrigerant in the refrigerant channel 820 continuously exchange heat, and the water is further heated by the condensation heat released by the condensation of the refrigerant, so that the hot water efficiency in the hot water system is further improved, and the energy consumption is reduced.

Specifically, the other end of the water flow path 810 communicates with the water inlet end of the water pump 300 through the second water inlet pipe 600. Thus, the water having sufficiently exchanged heat flowing through the plate heat exchanger 800 finally flows into the water pump 300 through the second water inlet pipe 600 and flows out to the outside through the second water outlet pipe 400 at the lower end of the water pump 300 for use, and the operation of the water pump 300 provides the pressure at which the water flows from the electric heating water tank 100 to the plate heat exchanger 800 and finally to the outside.

Alternatively, the plate heat exchanger 800 is vertically arranged, the water inlet end of the water channel 810 is located at the upper end, the water outlet end is located at the lower end, the air inlet end of the refrigerant channel 820 is located at the lower end, and the liquid outlet end is located at the upper end. In this way, the water in the water channel 810 flows from top to bottom, the refrigerant in the refrigerant channel 820 flows from bottom to top, the flow direction of the water is opposite to the flow direction of the refrigerant, and the heat exchange efficiency between the water and the refrigerant is further improved.

Specifically, the refrigerant is freon.

Optionally, the gaseous refrigerant pipe 830 is connected to an exhaust pipe of a compressor in the external refrigeration system, and the liquid refrigerant pipe 840 is connected to a liquid inlet of an evaporator in the external refrigeration system. In this way, the condensation heat of the external refrigeration system can be utilized to be introduced into the plate heat exchanger 800 to heat water, and the condensation heat is reused, so that the energy consumption is reduced, and the energy conservation and the environmental protection are realized.

Specifically, the external refrigeration system is a refrigeration system of a refrigerator or an air conditioner. In this way, the condensation heat in the refrigerating system of the refrigerator or the air conditioner can be led into the plate heat exchanger 800 through the gaseous refrigerant pipe 830 to heat the water in the water channel 810, so that the energy consumption is further reduced, the energy is saved, the environment is protected, and the cost of the hot water system is reduced.

Illustratively, when the external refrigeration system is a refrigeration system of a refrigerator, the plate heat exchanger 800 may utilize the heat of condensation to heat water in the water channel 810 at any time; when the external refrigeration system is a refrigeration system of an air conditioner, the condensation heat may be utilized to heat water in the water channel 810 when the air conditioner is operated in a cooling mode.

Optionally, a plurality of water channels 810 and refrigerant channels 820 are provided, and the plurality of water channels 810 and the plurality of refrigerant channels 820 are staggered. In this way, the plurality of water channels 810 and the plurality of refrigerant channels 820 are arranged in a staggered manner, so that the heat exchange area of water and refrigerant is increased, and the heat exchange efficiency is further improved.

Illustratively, the water flowing out from the first water outlet pipe 200 is uniformly distributed into the plurality of water channels 810 for circulation, and the high-temperature and high-pressure gaseous refrigerant flowing out from the refrigeration system is also uniformly distributed into the plurality of refrigerant channels 820 for circulation, so that the heat exchange of the water in the water channels 810 and the refrigerant in the refrigerant channels 820 is more sufficient.

It can be understood how the water in the plurality of water channels 810 is uniformly split at the water inlet end, the refrigerant in the plurality of refrigerant channels 820 is uniformly split at the air inlet end and flows into the liquid refrigerant pipe 840 at the water outlet end, which is not repeated herein.

In some embodiments, the hot water system further comprises: a bracket 900. The bracket 900 is fixedly connected with a wall at one side of the water pump 300, and the water pump 300 is fixed by the bracket 900. Thus, the water pump 300 is fixedly installed through the bracket 900, so that the water pump 300 is suspended, and vibration and noise generated when the water pump 300 works are reduced.

As shown in connection with fig. 4, 5, and 6, in one particular embodiment, the bracket 900 includes: a mounting plate 910 and a clip 920. The mounting plate 910 is fixedly connected with a wall at one side of the water pump 300; both ends of the yoke 920 are connected to the side wall of the mounting plate 910 by screws 930, and the water pump 300 is fixed to the inside of the yoke 920. In this way, the bracket 900 is divided into the mounting plate 910 and the clip 920, the mounting plate 910 is fixedly connected to the wall to provide support, and the clip 920 is used to fix the water pump 300, so that the stability of the water pump 300 can be improved. Both ends of the clamp 920 are connected with the side wall of the mounting plate 910 through screws 930, so that the stability of connection between the clamp 920 and the mounting plate 910 can be improved, and the clamp 920 can be conveniently detached.

Specifically, the mounting plate 910 is provided with a flange 911 extending toward the wall, and the flange 911 is provided with a fixing hole through which the expansion nail passes to be fixedly connected with the wall. In this way, the distance between the mounted water pump 300 and the wall is set, so that the stability of the water pump 300 is improved, and the vibration and noise generated by the operation of the water pump 300 are further reduced.

Specifically, the water inlet end and the water outlet end of the water pump 300 are both in tubular structures, the water inlet end and the water outlet end of the water pump 300 are both fixed through the bracket 900, the water inlet end of the water pump 300 is clamped inside the clamping band 920 of the bracket 900 corresponding to the water inlet end, and the water outlet end is clamped inside the clamping band 920 of the bracket 900 corresponding to the water outlet end. Thus, by arranging two brackets 900 to fix the water inlet end and the water outlet end of the upper end and the lower end of the pump body respectively, the stability of the water pump 300 can be further improved, and the vibration and noise generated in the operation of the water pump 300 can be reduced.

Specifically, sponge pads are respectively arranged between the water inlet end and the water outlet end and the corresponding clamp 920. In this way, wear during transportation can be reduced, and vibration of the water pump 300 can be reduced even when in use.

In another specific embodiment, as shown in connection with fig. 4 and 7, a bracket 900 includes: a mounting plate 910 and a clip 920. The mounting plate 910 is fixedly connected with a wall at one side of the water pump 300; one end of the clamp 920 is connected with the side wall of the mounting plate 910 through a screw 930, the other end is movably connected with the side wall of the mounting plate 910 through a card 921, and the water pump 300 is fixed on the inner side of the clamp 920. In this way, the bracket 900 is divided into the mounting plate 910 and the clip 920, the mounting plate 910 is fixedly connected to the wall to provide support, and the clip 920 is used to fix the water pump 300, so that the stability of the water pump 300 can be improved. One end of the clamp 920 is connected with the side wall of the mounting plate 910 through a screw 930, and the other end is movably connected with the side wall of the mounting plate 910 through a card 921, so that the number of the screws 930 is reduced, and the dismounting efficiency of the clamp 920 is further improved.

Optionally, a card slot 912 is provided on the side wall of the mounting plate 910 corresponding to the position of the card 921, and the card 921 is movably clamped in the card slot 912; when the card 921 is rotated to a position perpendicular to the card slot 912, the card 921 is locked with the card slot 912; when the card 921 is rotated to a position parallel to the card slot 912, the card 921 can be pulled out of the card slot 912. Thus, when the card 921 at the other end of the clip 920 is movably engaged with the card slot 912, and the water pump 300 is required to be fixed by the clip 920, the card 921 is rotated to a position perpendicular to the card slot 912, thereby locking the card 921 to the card slot 912. When the clamp 920 is required to be removed, the card 921 is rotated to a position parallel to the slot 912, and the card 921 is removed from the slot 912. When the clamp 920 needs to be disassembled, only the screw 930 at one end needs to be disassembled, and then the card 921 at the other end of the clamp 920 is rotated to the position parallel to the clamping groove 912, both ends of the clamp 920 can be disassembled, so that the water pump 300 is efficiently disassembled.
