Description

Technical Field

[0001] The invention relates to the technical field of solar water heaters, and in particular to a solar air heat pump integrated water heater. Background Art

[0002] A solar heat pump water heater is a water heating device that combines solar energy and heat pump technology. When there is sunlight, the water is heated by absorbing solar radiation through the solar collector. Specifically, when sunlight shines on the solar collector, the heat absorbing plate in the collector converts solar energy into thermal energy to heat the water or heat transfer medium in the collector. The heated water or heat transfer medium is transported to the water storage tank through a circulation pipeline. When solar energy is insufficient, a heat pump is used for heating. The compressor compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas, and then transports it to the condenser. In the condenser, the high-temperature and high-pressure refrigerant gas exchanges heat with the water in the water storage tank, transfers heat to the water, and raises the temperature of the water. This enables ordinary solar water heaters to be unrestricted by weather conditions.

[0003] However, current solar water heaters generally use two modes, self-circulation and forced circulation, during the heating process using collectors. In the self-circulation mode, the density difference between hot water and cold water is used as a driving force to achieve water circulation until all the water in the water tank is heated. However, in this process, after the hot water heated by the solar collector is added to the water tank, it will first mix with the unheated water in the water tank, thereby causing the water temperature of subsequent cycles to gradually rise, resulting in a gradual decrease in the circulation power in the self-circulation mode, thereby affecting the overall heating efficiency in the self-circulation mode.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] In the process of heating water, the solar water heater mainly heats the water through the solar collector, and finally completes the process of heating the water in the water tank 2. In the process of circulating heating, the water has two states: self-circulation mode and forced circulation mode. In the self-circulation mode, the density difference between hot water and cold water at both ends of the solar collector is used as the power to realize the circulation drive. In the forced circulation mode, an external water pump is used as the power to realize water circulation. However, in the current self-circulation mode, in the process of circulating heating, the water that starts to be heated will mix with the remaining unheated water in the water tank 2, and then enter the circulation process again. In this process. The water temperature in the water tank 2 gradually increases, resulting in a decrease in the density difference between hot water and cold water entering the solar heater, thereby affecting the power of the entire self-circulation mode and reducing it. After the speed of the self-circulation decreases, it will affect the efficiency of the overall self-circulation heating.

[0041] Reference Figure 1-Figure 7 A solar air heat pump integrated water heater includes a support mounting frame 1, on which are mounted: a plate collector 3, a water storage tank 2, a cold water delivery pipe 7, a hot water delivery member 9, a heat pump body 4, a first water pump 5, and a second water pump 6. The plate collector 3 is mounted on the top of the support mounting frame 1. The plate collector 3 and the heat pump body 4 are both used for heating the cold water in the water storage tank 2.

[0042] The water tank 2 is installed on one side of the bottom of the support mounting frame 1, and the support mounting frame 1 is provided with a water tank groove 101 for the water tank 2 to be installed. The inner cavity of the water tank 2 includes a hot water cavity 202 located at the upper end and a cold water cavity 201 located at the lower end. Two conducting partitions 203 are arranged in parallel in the hot water cavity 202. The two conducting partitions 203 divide the hot water cavity 202 into three interconnected water storage chambers, and the upper and lower water storage chambers have the same volume and are larger than the volume of the middle water storage chamber. Among them, the two conducting partitions 203 are respectively provided with a first partition 14 and a second partition 15 for blocking the communication between the water storage chambers, and the first partition 14 and the second partition 15 respectively divide the water storage chamber into three coaxially arranged storage spaces, and the three storage spaces have the same volume and can store hot water at different temperatures as needed to quickly meet the use needs. A driving member 8 for separately driving the first partition 14 and the second partition 15 is installed on the top of the water tank 2.

[0043] In the self-circulation mode, the driving member 8 first controls the first partition member 14 to rotate forward, and the first partition member 14 rotates forward to connect the water storage chambers in the middle layer and the lower layer. Figure 4, start to inject cold water into the bottom of the hot water cavity 202 until the cold water fills the middle layer and the lower layer, and start to heat the cold water by the plate collector 3. The heated hot water flows upward, and a density difference is formed between the hot water and the cold water, thereby driving the cold water in the water storage tank 2 to enter the plate collector 3 through the cold water delivery pipe 7. At the same time, the hot water heated by the plate collector 3 enters the upper end of the hot water cavity 202 of the water storage tank 2 through the hot water delivery member 9, and is finally stored in the water storage chamber of the upper layer. Since the cold water is consumed in the continuous circulation process, at this time, under the action of gravity, the cold water in the middle layer gradually enters the lower layer. Until all the cold water in the middle layer enters the lower layer, the driving member 8 rotates forward again, driving the first partition 14 to rotate again, so that the water storage chambers in the middle and lower layers are separated, and then the driving member 8 flips over, driving the second partition 15 to rotate, so that the water storage chambers in the middle and upper layers are opened and connected, as shown in FIG. Figure 5 The hot water in the upper layer begins to be stored in the middle layer, and the cold water is continuously circulated and heated. During the entire circulation heating process, the temperature of the cold water in the cold water delivery pipe 7 is always kept as constant as possible, so that the density difference between hot water and cold water remains constant, so as to maintain the power of self-circulation and improve the heating efficiency in the overall self-circulation mode.

[0044] At the same time, in order to ensure that the cold water in the hot water chamber 202 is circulated and heated thoroughly, one end of the cold water delivery pipe 7 is installed at the bottom end of the hot water chamber 202 and the other end is connected to the water inlet of the plate collector 3; one end of the hot water delivery member 9 is installed at the water outlet of the plate collector 3, and the other end is installed at the top of the hot water chamber 202 of the water storage chamber and extends to the three storage spaces formed by the second partition 15 respectively, so that water can be discharged from multiple positions during the water circulation process. A temperature control valve 10 is installed on the hot water delivery member 9. The setting of the temperature control valve 10 can be based on a preset temperature threshold. When the temperature is lower than the temperature threshold, the temperature control valve 10 is closed, so that the circulation temperature can be adjusted during the water circulation heating process, and the temperature control valve 10 can be wirelessly connected for remote control.

[0045] When solar energy is insufficient to heat the cold water, the heat pump body 4 is used to assist in heating the cold water to cope with weather conditions such as cloudy and rainy weather.

[0046] Specifically, the heat pump body 4 is installed on the other side of the bottom of the support mounting frame 1, and the water outlet of the heat pump body 4 is unidirectionally connected with the hot water conveying member 9, so that the hot water heated by the heat pump body 4 can flow into the water storage tank 2 through the hot water conveying member 9, and in the normal solar energy working state, the hot water is prevented from flowing back to the heat pump body 4, and the water outlet end of the first water pump 5 is connected with the water inlet of the heat pump body 4, and the water inlet end is connected with the hot water cavity 202 of the water storage tank 2. The first water pump 5 conveys the cold water in the water storage tank 2 to the heat pump body 4, and after being heated by the heat pump body 4, it is stored in the water storage tank 2.

[0047] When the solar energy is sufficient and the cold water in the hot water chamber 202 needs to be heated quickly in a short time, the forced circulation mode is started.

[0048] Specifically, the second water pump 6 is disposed on the top of the support mounting frame 1 and connected to the hot water conveying member 9. When working in the forced circulation mode, the driving member 8 first drives the first partition 14 and the second partition 15 to rotate, so that the upper, middle and lower water storage chambers in the hot water chamber 202 are all in a connected state. Figure 6 As shown, at this time, cold water enters the plate collector 3 through the cold water delivery pipe 7, and the second water pump 6 accelerates the hot water in the plate collector 3 to be transported to the water storage tank 2, so that the speed of the entire water circulation is accelerated, thereby improving the working efficiency of the plate heater.

[0049] Water injection pipes 204 are installed at the lower ends of the hot water chamber 202 and the cold water chamber 201 on the outside of the water storage tank 2 to realize the initial water injection of the cold water chamber 201 and the hot water chamber 202 in the water storage tank 2. An electric control valve is also installed at the end of the water injection pipe 204 to cooperate with the liquid level sensors installed in the hot water chamber 202 and the cold water chamber 201 to intelligently start the water injection process according to the real-time water level status.

[0050] When the hot water in the water storage tank 2 is heated and needs to be used:

[0051] A hot water output pipe 11 is installed on the outside of the water storage tank 2, and a cold water output pipe 12 is installed below the hot water output pipe 11. The cold water output pipe 12 is connected to the bottom of the cold water chamber 201. The hot water output pipe 11 includes a straight pipe and an L-shaped pipe, wherein a three-way valve is connected between the straight pipe and the L-shaped pipe. The three-way valve is a solenoid valve to open the connection state of the straight pipe or the L-shaped pipe as needed. The end of the straight pipe is installed at the bottom of the hot water chamber 202, so that water can be used directly from the bottom of the hot water chamber 202. The top of the L-shaped pipe is forked and connected with three branch pipes and distributed in the three storage spaces formed by the second partition 15. The purpose here is that when the storage spaces separated by the second partition 15 store water at different temperatures respectively, different water temperatures can be used separately according to needs, and when the heat pump body 4 is used to heat the water in the hot water chamber 202, in order to avoid mixing the heated cold water with the hot water, the water heated by the heat pump body 4 is directly stored, so that the water in the entire hot water chamber 202 does not need to be heated, and water can be used quickly in a short time.

[0052] When the driving member 8 drives the first partition member 14 and the second partition member 15 independently:

[0053] Specifically, the driving member 8 includes a driving motor 81 installed on the top of the water tank 2 and a driving shaft 82 connected to the output shaft of the driving motor 81. The driving motor 81 is a servo motor. The driving shaft 82 is respectively connected to the first partition 14 and the second partition 15 in the water tank 2. A one-way bearing is connected between the outer side of the driving shaft 82 and the first partition 14 and the second partition 15, and the two one-way bearings are in opposite directions, so that the driving shaft 82 can drive the first partition 14 or the second partition 15 to rotate on the conductive partition 203 alone. That is, when the driving motor 81 is working, when the driving shaft 82 drives the first partition 14 to rotate forward, under the action of the one-way bearing, the second partition 15 does not move. Similarly, when the driving shaft 82 drives the second partition 15 to flip, the first partition 14 does not move.

[0054] In the process of hot water delivery by the hot water delivery member 9, in order to ensure that the second water pump 6 does not work without affecting the entire pipeline, and at the same time be able to disperse and deliver the hot water to the three storage spaces of the same volume formed by the second partition 15:

[0055] Specifically, the hot water conveying member 9 includes a first conveying pipe 93 connected to the hot water outlet of the plate collector 3, a first three-way valve 92 installed on the first conveying pipe 93, a second conveying pipe 94 connected to the first conveying pipe 93 and a conveying main pipe 91 connected to the second conveying pipe 94. The end of the conveying main pipe 91 away from the second conveying pipe 94 is forked with three branches and respectively inserted into the top of the three storage spaces formed by the second partition 15. A temperature valve can also be installed at the end of each branch to realize separate storage of hot water at different temperatures. The temperature control valve 10 is installed at one end of the conveying main pipe 91 close to the second conveying pipe 94 to prevent hot water without detected temperature from entering the water storage tank 2.

[0056] In the forced circulation mode, the water inlet of the second water pump 6 is connected to a valve port of the first three-way valve 92, and the water outlet of the second water pump 6 is connected to the second delivery pipe 94. Under the control of the first three-way valve 92, the first delivery pipe 93 is in a closed state. The second water pump 6 directly delivers the hot water heated by the plate collector 3 into the second delivery pipe 94 through the first three-way valve 92, and finally delivers it to the water storage tank 2 through the delivery main pipe 91.

[0057] During the auxiliary heating process of the heat pump body 4:

[0058] A heat pump connecting pipe 401 is connected between the bottom water inlet at one end of the heat pump body 4 and the water outlet of the first water pump 5, and a heat pump outlet pipe 402 is connected to the top water outlet at the other end of the heat pump body 4, the top of the heat pump outlet pipe 402 is connected to the end of the delivery main pipe 91, and a one-way valve is installed at the top of the heat pump outlet pipe 402 to prevent liquid reflux, and the water inlet of the first water pump 5 is connected to the first heat pump water inlet pipe 403, the top of the first heat pump water inlet pipe 403 extends to the top of the water storage tank 2 and is forked into three branch pipes and are respectively inserted into the bottom of the three storage spaces formed by the second partition 15, and the middle part of the first heat pump water inlet pipe 403 is connected to the second heat pump water inlet pipe 404 through the second three-way valve, and the top of the second heat pump water inlet pipe 404 is installed on the bottom side of the hot water chamber 202.

[0059] When the heat pump body 4 is working, the cold water entering the heat pump body 4 can be directly pumped from the bottom of the hot water chamber 202, or pumped from the top of the hot water chamber 202, that is, the second partition 15 storage. The difference is that when solar energy is insufficient, but there is still solar energy, the solar collector will still heat the cold water in the hot water chamber 202 in the working state. Although the heating temperature is not enough for use, the heated warm water can be stored in the second partition 15 at this time. The first water inlet pipe 403 of the heat pump extends into the bottom of the second partition 15 to pump the warm water so that the warm water enters the heat pump body 4, thereby increasing the initial temperature difference in the heat pump body 4, thereby improving the heating efficiency of the heat pump body 4 under the same power. When there is no heated hot water in the second partition 15, water is directly pumped from the bottom of the hot water chamber 202 and the heated hot water is stored in the second partition 15, so as to achieve that the heated water of the heat pump body 4 is not mixed with most of the cold water in the hot water chamber 202. When a small amount of hot water is needed for quick use, this mode state can be used.

[0060] When the first partition 14 and the second partition 15 block the material guide baffle in the hot water chamber 202:

[0061] Reference Figure 1-Figure 10Specifically, the two ends of the conducting partition 203 are symmetrically provided with fan-shaped cutouts connecting the upper and lower water storage chambers. The first partition 14 has the same structure as the second partition 15, and only the vertical height is different to meet the needs of the water storage chambers in the middle and upper layers. The first partition 14 includes a coaxially arranged separation outer ring 141, a separation inner ring 142 and a separation bottom plate 144, wherein the radius of the separation bottom plate 144 is the same as that of the conducting partition 203, that is, the side of the separation bottom plate 144 is in contact with the inner wall of the hot water chamber 202. The partition bottom plate 144 is close to each other to achieve stability during rotation. The partition inner ring 142 and the partition outer ring 141 are fixed on the partition bottom plate 144, that is, the partition bottom plate 144 can drive the partition inner ring 142 and the partition outer ring 141 to rotate. The two ends of the partition bottom plate 144 are symmetrically provided with conveying channels 145 that match the fan-shaped cutouts. That is, when the conveying channels 145 correspond vertically to the fan-shaped cutouts, the water storage chamber between the upper and lower parts of the conductive partition 203 is in a connected state, and the connecting opening is open and adjustable.

[0062] Specifically, in order to enable the heated hot water to be quickly mixed with the cold water in the water tank 2 under the forced circulation state, guide plates 13 are provided on the inner wall of the hot water chamber 202, the inner wall of the partition inner ring 142 and the inner wall of the partition outer ring 141. When the first partition 14 and the conveying channel 145 of the second partition 15 correspond vertically, the guide plate 13 rotates from vertical to inclined, that is, the guide plate 13 is rotatably installed on the inner wall of the hot water chamber 202, the inner wall of the partition inner ring 142 and the inner wall of the partition outer ring 141. When the cold water in the water tank 2 is in the self-circulation mode and the forced circulation mode, the state of the guide plate 13 is different to adjust the diversion state. In the process of the guide plate 13 rotating back and forth, the scale on the inner wall of the hot water chamber 202, the inner wall of the partition inner ring 142 and the inner wall of the partition outer ring 141 can also be cleaned to reduce the influence of the scale on the water circulation heating efficiency.

[0063] Furthermore, since the inner wall of the hot water chamber 202, the inner wall of the separating inner ring 142 and the inner wall of the separating outer ring 141 are all arc-shaped, and the guide plate 13 can be adaptively fitted on the inner wall during rotation, the inner wall of the hot water chamber 202, the inner wall of the separating inner ring 142 and the inner wall of the separating outer ring 141 are all provided with mounting holes 143 for installing the guide plate 13. The guide plate 13 includes a rotating motor 132 embedded in the mounting hole 143 and an arc-shaped plate 131 connected to the rotating motor 132. The rotating motor 132 is driven by a wireless connection, and as shown in the figure, the arc-shaped plate 131 can be in a variety of states according to the operation of the rotating motor 132 to adapt to different usage requirements. One side of the arc-shaped plate 131 is fitted on the inner wall of the hot water chamber 202, the inner wall of the separating inner ring 142 and the inner wall of the separating outer ring 141, and the fitting parts at both ends of the arc-shaped plate 131 are elastically arranged. During the rotation of the arc plate 131 , the elastic arrangement of the two ends enables the arc plate 131 to still be in close contact with the inner wall of the hot water chamber 202 , the inner wall of the partition inner ring 142 and the inner wall of the partition outer ring 141 after rotation.
