Description

Technical Field

[0001] The present invention relates to the technical field of heat pump machines, and specifically to an energy-saving dual-source heat pump unit system. Background Art

[0002] In modern times of rapid technological development, all walks of life are undergoing rapid changes, which has led to a huge increase in energy consumption in the fields of production and life of the whole society. Energy has become the most critical social and economic issue of this century. The demand for traditional primary energy is increasing day by day, but the output is limited, so the consumption cost is getting higher and higher. With the development of society and the improvement of people's living standards, the energy consumption for heating, air conditioning, and producing domestic hot water accounts for an increasing proportion of the total energy. Therefore, vigorously developing and effectively using renewable energy has become the priority development strategy of various countries; heat pumps, as an energy-saving technology, have been widely regarded by countries around the world. Among them, air source and water source are the most widely used because these two types of heat pumps are convenient to use and have relatively low installation costs. At the same time, no pollutants are generated during the operation of the system, which is very in line with the trend and policy of energy conservation and environmental protection in China.

[0003] In the process of using a heat pump unit to provide hot water in the prior art, usually the hot water is stored first. Subsequently, during the process of using the hot water, it is necessary to control the amount of hot water discharged according to the position of the switch to adjust the water flow temperature. When not familiar with the water flow switch, directly opening the water flow switch is likely to cause harm to the user. Therefore, in the prior heat pump units, the water is usually heated to a certain temperature for insulation, and the heated water temperature is generally not too high to adapt to people's use at any time and avoid the hot water causing harm to the user during use. The relatively low heated water temperature will reduce the use efficiency of the heat pump unit, and the relatively low water temperature will also lead to an accelerated consumption rate of the hot water, thus making it difficult to meet the long-term use.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. During the operation of the heat pump, the present invention uses the mixing box and the detection box to make the discharged hot water more suitable for people to use. The heat expansion oil enables the second baffle to automatically and continuously adjust the amount of cold water entering the second water inlet according to the temperature of the hot water. Therefore, during the use of hot water, the discharged hot water can be mixed with a part of cold water first, so that the temperature of the discharged hot water is within a range harmless to the human body, avoiding directly discharging hot water, which is likely to cause harm to the user. Moreover, the second water inlet is close to the side of the discharge cylinder, and the hot water flowing in the first water inlet will pass through the second water inlet, preventing the hot water from directly flowing into the discharge cylinder and causing harm to the subsequent human body. During the process of discharging hot water, the detection box can automatically adjust the amount of cold water added according to the temperature of the hot water, ensuring that the discharged hot water is within a certain temperature range. Thus, when heating water, the water can be directly heated to a relatively high temperature. On the one hand, it avoids wasting energy by heating the water to a relatively low temperature and then not heating it anymore. On the other hand, heating the water to a relatively high temperature can increase the total amount of water after mixing the hot water with a higher temperature and cold water during subsequent use, thereby ensuring the long-term use of hot water.

[0017] 2. After the water flow is heated and flows into the water storage bucket, the volume of the heat expansion oil inside the fixed cylinder will increase under the action of the hot water. The heat expansion oil will act on the sliding plate to move upward, and the first sealing plate and the second sealing plate will extend together with the sliding plate. The first sealing plate will seal the opening on the surface of the fixed cylinder, and the second sealing plate will seal the connection port between the connecting cylinder and the water storage bucket, preventing the hot water from entering the connecting cylinder. When the water temperature in the water storage bucket decreases to a certain temperature after a long time of storage, the volume of the heat expansion oil will gradually decrease, and the sliding plate will move downward. The second sealing plate will contract, and the connection port between the communicating cylinder and the water storage bucket will be exposed. The hot water in the storage bucket will enter the water inlet pipe through the connecting cylinder and re-enter the heating outer cylinder together with the water flow in the water inlet pipe for heating. This is beneficial for automatically re-inputting the water inside the storage bucket into the water inlet pipe for reheating when the temperature of the hot water stored in the water storage bucket decreases, ensuring the water temperature when using hot water and avoiding the situation where the water temperature cannot meet the user's demand for hot water after it decreases.

[0018] 3. In the process of using hot water in the present invention, hot water will enter between the first partition plate and the second partition plate through the water outlet cylinder and the first water inlet, and cold water will enter between the first partition plate and the second partition plate through the second water inlet. The rotation of the mixing fan blades will stir the hot water and the cold water, which is conducive to the rapid mixing of the hot water and the cold water, avoiding the hot water from gathering and rushing out and failing to fully mix with the cold water. The hot water will directly flow to the discharge cylinder and cause harm to the human body. BRIEF DESCRIPTION OF THE DRAWINGS

A first partition plate 18 and a second partition plate 19 are fixedly connected inside the mixing box 17. The first partition plate 18 and the second partition plate 19 divide the interior of the mixing box 17 into three parts. The first partition plate 18 is located above the second partition plate 19.

[0035] During the operation of the heat pump, the driving fan blade 11 will guide the air towards the inside of the support frame 6, and the air will flow from the inside of the support frame 6 to the positions of the plurality of fixing plates 7 and the heat absorption pipes 9. The gas medium in the heat absorption pipes 9 will absorb the heat in the air through the heat absorption pipes 9. The gas medium after absorbing the heat will pass through the heat absorption pipes 9 and the connecting pipes 8 and flow to the compressor 4. The compressor 4 will compress the gas medium into a liquid and release heat. The compressed gas medium will be discharged into the condenser pipe 5. The compressed gas medium will release heat during the process of moving in the condenser pipe 5. Subsequently, after the compressed gas medium flows through the condenser pipe 5, it will flow to the expansion valve 10. The gas medium compressed into a liquid will expand back into a gas again. The gas medium will flow back into the heat absorption pipes 9 through the connecting pipes 8 to absorb heat. When heating the water flow, the water flow will enter the mixing box 17 through the water inlet pipe 15. Subsequently, the water flow will pass through the mixing box 17 from below the second partition plate 19 in the mixing box 17 and flow between the heat exchange outer cylinder 13 and the heat exchange inner cylinder 12. The water flow will accumulate between the heat exchange inner cylinder 12 and the heat exchange outer cylinder 13. The water flow will be heated by the heat released by the gas medium in the condenser pipe 5 between the heat exchange inner cylinder 12 and the heat exchange outer cylinder 13. Subsequently, the water flow will flow to the position of the connecting pipe 8 and then flow to the bottom of the adjacent heat exchange outer cylinder 13 through the connecting pipe 14. After the water flow passes through the inside of the plurality of heat exchange outer cylinders 13, the water flow will be heated. Subsequently, the water flow will flow to the position of the water outlet pipe 1501. The heated water flow will flow into the water storage bucket 3 through the water outlet pipe 1501 for heat preservation storage. The hot water in the water storage bucket 3 will enter the mixing box 17 through the water outlet cylinder 16. Subsequently, when hot water is needed, after opening the hot water switch, the driving plate 22 will act on the first baffle plate 23 to move it out above the first water inlet 21, and the first water inlet 21 will be exposed. The hot water in the water storage bucket 3 will enter between the first partition plate 18 and the second partition plate 19 through the first water inlet 21. When the hot water flows to the position of the detection box 25, the volume of the thermal expansion oil inside the detection box 25 will change under the action of the hot water, and the push plate 26 and the second baffle plate 27 will move under the action of the thermal expansion oil, and the second water inlet 24 will be exposed. The water in the water inlet pipe 15 will enter between the first partition plate 18 and the second partition through the second water inlet 24 for mixing, making the discharged hot water more suitable for people to use. Using the thermal expansion oil enables the second baffle plate 27 to automatically and continuously adjust the amount of cold water entering through the second water inlet 24 according to the temperature of the hot water. Thus, it is beneficial that during the use of hot water, the discharged hot water can be mixed with a part of cold water first, so that the temperature of the discharged hot water is within a range harmless to the human body, avoiding directly discharging hot water, which is likely to cause harm to the user. And the second water inlet 24 is close to the discharge cylinder 20 side, and the hot water flowing in the first water inlet 21 will pass through the second water inlet 24, avoiding the hot water flowing directly into the discharge cylinder 20 and causing harm to the subsequent human body. During the process of discharging hot water, the detection box 25 can automatically adjust the amount of cold water added according to the temperature of the hot water.Ensure that the discharged hot water is within a certain temperature range, so that when heating water, the water can be directly heated to a relatively high temperature. On the one hand, it avoids wasting energy by heating the water to a relatively low temperature and then not heating it anymore. On the other hand, heating the water to a relatively high temperature can increase the total amount of water when the hot water is mixed with cold water during subsequent use, thus ensuring the long-term use of hot water. Subsequently, after the hot water with a suitable temperature is normally discharged, when it is necessary to adjust the temperature of the hot water during use according to one's own needs, the blocking range of the third baffle 28 for the second water inlet 24 is adjusted by the handle 30, so as to adjust the cold water passing through the second water inlet 24, and the addition amount of cold water during the mixing process can be manually adjusted to adapt to the different use temperatures that the hot water can be adjusted to according to needs during use. During the process of moving and adjusting the third baffle 28, the positioning rod 29 will move together. When the end of the third baffle 28 moves to the position below the second baffle 27 and seals the second water inlet 24, the positioning rod 29 will be clamped between the second baffle 27 and the third baffle 28 to position the maximum adjustment range of the third baffle 28, avoiding useless adjustment after the third baffle 28 and the second baffle 27 block the second water inlet 24.

[0036] After the water flow is heated and stored for a long time, the water temperature in the water storage bucket 3 will decrease. As a further solution of the present invention, the water inlet pipe 15 and the water storage bucket 3 are communicated through a connecting cylinder 31. The connecting cylinder 31 is located between the mixing box 17 and the heat exchange outer cylinder 13. A fixed cylinder 32 is fixedly connected to the bottom of the inner wall of the water storage bucket 3. The fixed cylinder 32 is located at the middle position of the water storage bucket 3. The fixed cylinder 32 stores thermal expansion oil inside. A sliding plate 33 is slidably and sealingly connected inside the fixed cylinder 32. The sliding plate 33 penetrates through the fixed cylinder 32 and extends to the end position of the fixed cylinder 32 on the inner wall surface of the water storage bucket 3. A telescopic first sealing plate 34 is connected between the surface of the sliding plate 33 and the bottom of the inner wall of the fixed cylinder 32. The first sealing plate 34 is slidably and sealingly connected to the inner wall of the fixed cylinder 32. A telescopic second sealing plate 35 is fixedly connected between the surface of the sliding plate 33 and the bottom of the inner wall of the water storage bucket 3. The second sealing plate 35 is slidably and sealingly connected to the inner wall surface of the water storage bucket 3. The second sealing plate 35 is located at the end position of the connecting cylinder 31;

[0037] After the water flow is heated and flows into the water storage bucket 3, the volume of the thermal expansion oil inside the fixed cylinder 32 will increase under the action of the hot water. The thermal expansion oil will act on the sliding plate 33 to move upward. The first sealing plate 34 and the second sealing plate 35 will extend together with the sliding plate 33. The first sealing plate 34 will seal the opening on the surface of the fixed cylinder 32, and the second sealing plate 35 will seal the connection port between the connecting cylinder 31 and the water storage bucket 3, so that the hot water will not enter the connecting cylinder 31. When the water temperature in the water storage bucket 3 drops to a certain temperature after being stored for a long time, the volume of the thermal expansion oil will gradually decrease, the sliding plate 33 will move downward, the second sealing plate 35 will contract, and the connection port between the communicating cylinder and the water storage bucket 3 will be exposed. The hot water in the storage bucket will enter the water inlet pipe 15 through the connecting cylinder 31 and the water flow in the water inlet pipe 15 will re-enter the inside of the heating outer cylinder for heating. This is beneficial to automatically input the water inside the storage bucket back into the water inlet pipe 15 for reheating when the temperature of the hot water stored inside the water storage bucket 3 drops, ensuring the water temperature when using hot water and avoiding the situation that the water temperature cannot meet the user's demand for hot water after it drops.

[0038] During the process of using hot water, the hot water cannot be fully mixed with cold water. As a further solution of the present invention, a mixing fan blade 36 is fixedly installed on the bottom surface of the first partition plate 18;

[0039] During the process of using hot water, the hot water will enter between the first partition plate 18 and the second partition plate 19 through the water outlet cylinder 16 and the first water inlet 21, and the cold water will enter between the first partition plate 18 and the second partition plate 19 through the second water inlet 24. The rotation of the mixing fan blade 36 will stir the hot water and the cold water, which is beneficial to quickly mix the hot water and the cold water, avoiding the situation that the hot water will gather and rush out, cannot be fully mixed with the cold water, and the hot water will directly flow to the discharge cylinder 20 to cause harm to the human body.

[0040] When there is more water stored in the water storage bucket 3, the water flow will overflow. As a further solution of the present invention, a floating block 37 is slidably connected to the inner wall surface of the water storage bucket 3, and the floating block 37 is located at the position of the water outlet pipe 1501;

[0041] When there is more water in the water storage bucket 3, the floating block 37 will move upward along with the water storage liquid level in the water storage bucket 3. When the floating block 37 moves to the position of the water outlet pipe 1501, the floating block 37 will block the end of the water outlet, avoiding too much water in the water storage bucket 3.

[0042] After the hot water enters the water storage bucket 3, the sliding plate 33 will drive the second sealing plate 35 to move to seal the end of the connecting cylinder 31. When the water flow drops, it will impact the sliding plate 33, resulting in the connecting cylinder 31 not being sealed by the second sealing plate 35. As a further solution of the present invention, a fourth blocking plate 38 is fixedly connected to the surface of the sliding plate 33, and the fourth blocking plate 38 slides on the inner wall surface of the water storage bucket 3;

[0043] After hot water enters the water storage bucket 3, the sliding plate 33 drives the second sealing plate 35 to extend. The second sealing plate 35 seals the end of the connecting cylinder 31, and the fourth baffle plate 38 blocks the upper part of the sliding plate 33. When the water flow falls and impacts the sliding plate 33, the fourth baffle plate 38 can block the upper part of the sliding plate 33, preventing the sliding plate 33 from shaking due to the impact of the water flow, so that the connecting cylinder 31 cannot be completely sealed by the second sealing plate 35, and the water flow in the connecting cylinder 31 enters the water storage bucket 3, affecting the water temperature in the water storage bucket 3.
