Description

Technical Field

[0002] A heat pump water heater is a device that uses heat pump technology to heat water; the working principle of a heat pump water heater is to absorb low-temperature heat energy from an environmental heat source (such as water, air) through components such as a compressor, an evaporator, a heat exchanger, a heat preservation water tank, and an electronic automatic controller, and then convert it into high-temperature heat energy and release it into a circulating medium (such as water, air) to become a high-temperature heat source output.

[0003] The heat pump water heater of the related technology includes a vertical water tank, and a water inlet pipe and a water outlet pipe are connected to the vertical water tank. When the heat pump water heater heats the vertical water tank, since the density of water changes with temperature, the density of cold water is greater than that of hot water. When heating, the hot water will flow towards the top of the vertical water tank, and the cold water will flow towards the bottom of the vertical water tank, resulting in a temperature stratification phenomenon in the water tank.

[0004] When the user discharges water through the water outlet pipe, the temperature stratification phenomenon in the vertical water tank will cause uneven water outlet temperature of the water outlet pipe, which is not convenient for the user to judge the water outlet temperature of the water outlet pipe. Summary of the Utility Model

Detailed description of the specific embodiments

[0032] The heat pump water heater in the related art includes a vertical water tank, and an inlet and an outlet are connected to the vertical water tank and communicate with the vertical water tank. When the heat pump water heater heats the vertical water tank, since the density of water changes with temperature, the density of cold water is greater than that of hot water. When heating, the hot water will flow towards the top of the vertical water tank, and the cold water will flow towards the bottom of the vertical water tank, resulting in a temperature stratification phenomenon in the water tank.

[0033] When the user discharges water through the outlet, the temperature stratification phenomenon in the vertical water tank will cause uneven water outlet temperature at the outlet, which is not convenient for the user to judge the water outlet temperature at the outlet.

[0034] To solve the above technical problems, the present application provides a water tank of a water heater and a heat pump water heater. By arranging the outlet at the top of the box body, the hot water gathered at the top of the box body can be discharged along the outlet, preventing uneven water outlet temperature at the outlet; a first temperature probe is arranged at the outlet, and the first temperature probe can detect the water outlet temperature at the outlet in real time and display the water outlet temperature on the display board of the heat pump water heater in real time, so as to facilitate the user to judge the water outlet temperature at the outlet and indirectly improve the safety of the user when discharging water for use; by using a second temperature probe to detect the water use temperature of the inner wall of the box body, it is convenient to start and stop the heat pump unit according to the water use temperature in the box body, so that there is more hot water meeting the requirements in the box body, and further prevent uneven water outlet temperature at the outlet.

[0035] Embodiment 1

[0036] As Figure 1As shown in the figure, a water tank of a water heater includes a box body 100 and a first detection mechanism 200. The box body 100 is provided with a water inlet 110 and a water outlet 120. The water inlet 110 is arranged at the top or bottom of the box body 100, and the water outlet 120 is arranged at the top or bottom of the box body 100. The first detection mechanism 200 is arranged inside the water outlet 120 or on the outer wall of the water outlet 120. The first detection mechanism 200 is configured to detect the water temperature of the water outlet 120 and display the water temperature on the display board of the heat pump water heater.

[0037] In this embodiment, the cross-section of the box body 100 is circular. The water inlet 110 is arranged at the top of the side wall of the box body 100, and the water outlet 120 is arranged at the bottom of the side wall of the box body 100. The water inlet 110 and the water outlet 120 are arranged on the same side of the box body 100. The first detection mechanism 200 can be arranged inside the water outlet 120 or outside the water outlet 120. The water inlet 110 is used to communicate with the water supply end, and the water outlet 120 is used to communicate with the water using end. In other embodiments, the shape of the box body 100 can be adjusted adaptively according to needs. For example, the shape of the box body 100 can be set to be rectangular. The positions of the water inlet 110 and the water outlet 120 can be adjusted adaptively according to needs. The position of the first detection mechanism 200 can be adjusted adaptively according to needs.

[0038] By adopting the above technical solution, by arranging the water inlet 110 at the bottom of the box body 100 and the water outlet 120 at the top of the box body 100, since the density of water changes with temperature, the density of cold water is greater than that of hot water. When heating, the hot water will flow towards the top of the box body 100, and the cold water will flow towards the bottom of the box body 100. The hot water can gather at the top of the box body 100 and flow out along the water outlet 120, thereby preventing the phenomenon of uneven temperature at the water outlet 120. By adopting the arrangement of the first detection mechanism 200, the first detection mechanism 200 can detect the water temperature of the water outlet 120 and display the water temperature on the display board of the heat pump water heater, so as to facilitate the user to judge the water temperature of the water outlet 120 and indirectly improve the safety of the user when discharging water for use.

[0039] As Figure 1 shown, the first detection mechanism 200 includes a first temperature probe 210.

[0040] By adopting the above technical solution, the first temperature probe 210 can monitor the water outlet temperature of the water outlet 120 in real time, ensuring the stability and reliability of hot water supply. By precisely controlling the water outlet temperature, the energy utilization efficiency of the heat pump water heater can be effectively improved, and energy waste can be reduced; the use of the first temperature probe 210 helps prevent the heat pump water heater from operating under abnormal conditions, such as overheating that may cause equipment damage or safety accidents, and these risks can be effectively avoided through real-time monitoring; by adopting the setting of the first temperature probe 210, it can work stably under different environmental conditions, including extreme temperatures or harsh environments, ensuring that the heat pump water heater can operate stably under various working conditions.

[0041] In other embodiments, the first temperature probe 210 can be replaced with a semiconductor temperature sensor: such as an NTC thermistor. The NTC thermistor uses the characteristic that the resistance of semiconductor materials changes with temperature to detect temperature, and has the advantages of fast response speed, small volume, and low cost; the first temperature probe 210 can also be replaced with a thermocouple. The thermocouple measures temperature by generating a potential difference at the junction of two different metals at different temperatures and is suitable for high-temperature measurements; the first temperature probe 210 can also be replaced with a platinum resistance sensor. The platinum resistance sensor is based on the characteristic that the resistance of metals increases with temperature rise, with accurate measurement and good stability.

[0042] As Figure 1 shown, the water tank of the water heater further includes a second detection mechanism 300. The second detection mechanism 300 is disposed inside the box body 100 or on the outer wall of the box body 100. The second detection mechanism 300 is configured to detect the water usage temperature of the water in the box body 100, and when the water usage temperature is greater than or equal to the preset temperature, control the heat pump unit 600 of the heat pump water heater to stop operating; when the water usage temperature is less than the preset temperature, control the heat pump unit 600 to start operating.

[0043] In this embodiment, the second detection mechanism 300 is disposed inside the box body 100; when the water in the box body 100 is used as general domestic water, the preset temperature can be set to 40°C to 45°C, and when the water in the box body 100 is used for bathing, the preset temperature can be set to 37°C to 40°C; if it is for children's bathing, the preset temperature can be set lower, and if it is for washing dishes, the preset temperature can be set higher; in other embodiments, the second detection mechanism 300 can be disposed on the outer wall of the box body 100; the preset temperature can be adjusted adaptively according to needs.

[0044] By adopting the above technical solution, with the arrangement of the second detection mechanism 300, the water temperature inside the box body 100 can be detected. By comparing the water temperature with the preset temperature, the start and stop of the heat pump unit 600 can be realized; detecting the water temperature inside the box body 100 helps to maintain the stability of hot water supply, ensuring that users can obtain hot water at a suitable temperature at any time and improving the user experience; and through the detection of the water temperature, the operation of the heat pump unit 600 can be reasonably controlled, avoiding equipment wear caused by frequent start and stop or long-term operation, and helping to extend the service life of the heat pump water heater.

[0045] As Figure 1 shown, the second detection mechanism 300 includes a second temperature probe 310.

[0046] By adopting the above technical solution, the second temperature probe 310 can monitor the water temperature inside the box body 100 in real time, ensuring the stability and reliability of hot water supply. By precisely controlling the water temperature, the energy utilization efficiency of the heat pump water heater can be effectively improved, reducing energy waste; the use of the second temperature probe 310 helps to prevent the heat pump water heater from working under abnormal conditions. For example, overheating may cause equipment damage or safety accidents, and these risks can be effectively avoided through real-time monitoring; by adopting the arrangement of the second temperature probe 310, it can work stably under different environmental conditions, including extreme temperatures or harsh environments, ensuring that the heat pump water heater can operate stably under various working conditions.

[0047] In other embodiments, the second temperature probe 310 can be replaced with a semiconductor temperature sensor: such as an NTC thermistor. The NTC thermistor uses the characteristic that the resistance of semiconductor materials changes with temperature to detect temperature, and has the advantages of fast response speed, small volume, and low cost; the second temperature probe 310 can also be replaced with a thermocouple. The thermocouple measures temperature by generating a potential difference at the junction of two different metals at different temperatures and is suitable for high-temperature measurement; the second temperature probe 310 can also be replaced with a platinum resistance sensor. The platinum resistance sensor measures accurately and has good stability based on the characteristic that the resistance of metals increases with temperature rise.

[0048] As Figure 1 shown, the water tank of the water heater further includes a connector 400. The connector 400 is arranged inside the box body 100, and the connector 400 is used to fixedly arrange the second temperature probe 310 in the middle of the box body 100.

[0049] By adopting the above technical solution, since hot water will flow towards the top of the box body 100 during heating and cold water will flow towards the bottom of the box body 100, by fixedly arranging the second temperature probe 310 in the middle of the box body 100, the second temperature probe 310 can detect the water temperature for use in the middle of the box body 100. The water temperature detected by the second temperature probe 310 is neither too high nor too low, enabling the heat pump unit 600 to further heat the water in the box body 100, thereby indirectly making the box body 100 have more hot water meeting the requirements and increasing the hot water output of the box body 100; by adopting the arrangement of the connecting member 400, the second temperature probe 310 can be fixed in the middle of the box body 100, improving the fixing strength of the second temperature probe 310 in the box body 100 and preventing the second temperature probe 310 from falling off due to the water flow in the box body 100.

[0050] As Figure 1 shown, the connecting member 400 includes a connecting rod 410. One end of the connecting rod 410 is connected to the inner top wall of the box body 100, and the other end extends to the middle of the box body 100. The second temperature probe 310 is arranged at the end of the connecting rod 410 located in the middle of the box body 100.

[0051] In this embodiment, the connecting rod 410 is arranged along the axial direction of the box body 100. One end of the connecting rod 410 can be connected to the inner top wall of the box body 100 by means of bolt connection or welding; the second temperature probe 310 can be detachably connected to the other end of the connecting rod 410 by means of bolt connection; in other embodiments, the connecting rod 410 can be set as a telescopic rod. By setting the telescopic rod, the second temperature probe 310 can be driven to move in the box body 100 along the height direction of the box body 100, so as to facilitate adjusting the position of the second temperature probe 310 in the box body 100, enabling the same second temperature probe 310 to detect the water temperature at different positions in the box body 100; the end of the telescopic rod close to the inner top wall of the box body 100 can also be hinged inside the box body 100, so that the telescopic rod can rotate horizontally inside the box body 100, further adjusting the position of the second temperature probe 310 and enabling the second temperature probe 310 to further detect the water temperature at different positions in the box body 100.

[0052] By adopting the above technical solution, by adopting the arrangement of the connecting rod 410, its structure is simple, convenient for production and manufacturing, reducing the production and manufacturing cost of the connecting member 400; and adopting the arrangement of the connecting rod 410 is convenient for installers to install the second temperature probe 310, improving the convenience during the installation of the second temperature probe 310.

[0053] Embodiment Two

[0054] The difference between this embodiment and Embodiment One is that:

[0055] AsFigure 2 As shown, the second detection mechanism 300 includes a plurality of third temperature probes 320, and the plurality of third temperature probes 320 are evenly distributed along the height direction of the box body 100.

[0056] In this embodiment, three third temperature probes 320 are provided. The three third temperature probes 320 are all located inside the box body 100, and the three third temperature probes 320 are respectively arranged at the top, middle and bottom of the box body 100. By arranging a mounting rod 500 along the height direction of the box body 100 inside the box body 100, one end of the mounting rod 500 is connected to the inner top wall of the box body 100, and the other end of the mounting rod 500 is connected to the inner bottom wall of the box body 100. By detachably connecting the three third temperature probes 320 to the top, middle and bottom ends of the mounting rod 500 with bolts, the three third temperature probes 320 are arranged at the top, middle and bottom of the box body 100.

[0057] By adopting the above scheme, by arranging a plurality of third temperature probes 320, the plurality of third temperature probes 320 can detect the temperature of water at different positions in the box body 100, thereby improving the accuracy of the temperature detection of the water in the box body 100, and facilitating the second detection mechanism 300 to accurately control the start and stop of the heat pump unit 600 through the temperature of the water in the box body 100; and the third temperature probe 320 can monitor the water temperature in the box body 100 in real time, ensuring the stability and reliability of the hot water supply. By accurately controlling the water temperature, the energy utilization efficiency of the heat pump water heater can be effectively improved, and energy waste can be reduced; the use of the third temperature probe 320 helps to prevent the heat pump water heater from working under abnormal conditions, such as overheating may cause equipment damage or safety accidents, and these risks can be effectively avoided through real-time monitoring; by adopting the arrangement of the third temperature probe 320, it can work stably under different environmental conditions, including extreme temperatures or harsh environments, ensuring that the heat pump water heater can operate stably under various working conditions.

[0058] In other embodiments, the third temperature probe 320 can be replaced with a semiconductor temperature sensor: such as an NTC thermistor. The NTC thermistor uses the characteristic that the resistance of semiconductor materials changes with temperature to detect temperature, and has the advantages of fast response speed, small volume and low cost; the third temperature probe 320 can also be replaced with a thermocouple. The thermocouple measures temperature by generating a potential difference at the junction of two different metals at different temperatures and is suitable for high-temperature measurement; the third temperature probe 320 can also be replaced with a platinum resistance sensor. The platinum resistance sensor is based on the characteristic that the resistance of metals increases with the increase of temperature, and has accurate measurement and good stability.

[0059] Such as Figure 2As shown, a plurality of third temperature probes 320 are configured to detect the water usage temperature at the positions where each third temperature probe 320 is located in the box body 100, calculate the average temperature of the plurality of water usage temperatures, and when the average temperature is greater than or equal to the preset temperature, control the heat pump unit 600 of the heat pump water heater to stop operating; when the average temperature is less than the preset temperature, control the heat pump unit 600 to start operating.

[0060] By adopting the above technical solution, through the setting of the plurality of third temperature probes 320, the temperature of the water at different positions in the height direction of the box body 100 can be detected, so as to obtain the water usage temperature of the water at different positions in the box body 100. By calculating the average temperature of the plurality of water usage temperatures and comparing the average temperature with the preset temperature, the start and stop of the heat pump unit 600 are realized, further improving the accuracy of the start and stop of the heat pump unit 600, so that there is more hot water vertically, further increasing the water output of the box body 100, helping to maintain the stability of the hot water supply, ensuring that users can obtain hot water at a suitable temperature at any time, and improving the use experience; and it can avoid equipment loss caused by frequent start and stop or long-term operation, helping to extend the service life of the heat pump water heater.

[0061] As Figure 3 shown, the embodiment of the present application further provides a heat pump water heater, including a heat pump unit 600 and the water tank of the water heater according to any one of the above embodiments provided on the heat pump unit 600.

The first detection mechanism 200 is provided outside or inside the outlet pipe 121, and the first detection mechanism 200 is provided on the water outlet 120 through the outlet pipe 121; in this embodiment, an inlet pipe 111 is provided on the box body 100 at the position where the water inlet 110 is located; the first detection mechanism 200 is provided on the inner wall of the outlet pipe 121, so as to improve the accuracy of the first detection mechanism 200 for detecting the water temperature in the outlet pipe 121.

[0064] As Figure 3 shown, the heat pump unit 600 includes an evaporator 610, a compressor 620, a condenser 630 and a water-saving mechanism 640. The evaporator 610 is used for heat exchange with the environment to evaporate the refrigerant into a gas. The compressor 620 is used to compress the gas to form a high-temperature and high-pressure gas. The condenser 630 is used to heat the box body 100 by using the high-temperature and high-pressure gas. The water-saving mechanism 640 is used to adjust the flow rate of the refrigerant.

[0065] In this embodiment, the condenser 630 can be arranged as a microchannel wound around the outer wall of the box body 100; the high-temperature and high-pressure gas compressed by the compressor 620 can enter the microchannel, thereby heating the box body 100; the throttling mechanism can adopt an electronic expansion valve, a thermostatic expansion valve or a capillary tube.

[0066] By adopting the above technical solution, the heat pump water heater composed of the evaporator 610, the compressor 620, the condenser 630, the water-saving mechanism 640 and the box body 100 uses the heat pump principle, drives the compressor 620 to work with a small amount of electric energy, absorbs free heat energy from the air, and has a thermal efficiency much higher than that of traditional electric water heaters; due to the high thermal efficiency, using the heat pump water heater can reduce the power consumption, thereby reducing carbon emissions and being beneficial to environmental protection; the heat pump water heater is not affected by the external climate and can stably supply hot water whether it is rainy or at night; the heat pump water heater has no combustion process, avoiding the risks of gas leakage or carbon monoxide poisoning and being safer to use; the equipped water-saving mechanism 640 can adjust the refrigerant flow rate, reduce water resource waste, improve water use efficiency, and conform to the concept of energy conservation and emission reduction.
