[0068] Those skilled in the art can understand that the system platform architecture 1000 can be applied to 5G communication network systems and subsequent evolved mobile communication network systems, etc. The present embodiment does not make specific limitations on this.

[0069] Those skilled in the art can understand that Figure 1 the system platform architecture 1000 shown in

[0070] Reference Figure 2 , Figure 2 FIG. 1 is a schematic structural diagram of an integrated heat pump water heater provided by an embodiment of the present invention. The integrated heat pump water heater includes:

[0071] A water storage module 200 for storing water;

[0072] A main unit module 400 for heating the water in the water storage module 200 through a heat pump cycle; the main unit module 400 and the water storage module 200 are integrally arranged in a water heater housing 100. The main unit module 400 is located at a first end inside the water heater housing 100, and the water storage module 200 is located at a second end inside the water heater housing 100. The main unit module 400 is connected to the water storage module 200 through a detachable connection structure;

[0073] An auxiliary heating module 300 is arranged on the water outlet path of the main unit module 400 for auxiliary heating of the water outlet of the main unit module 400;

[0074] A temperature detection module for detecting a first water temperature value before heating by the auxiliary heating module 300 and a second water temperature value after heating;

[0075] A control module for controlling a first working mode of the main unit module 400 and the auxiliary heating module 300 according to the first water temperature value and the second water temperature value.

[0076] It should be noted that the integrated setting of the water storage module 200 and the main unit module 400 of the present application can set the water storage module 200 above the main unit module 400, or arrange the water storage module 200 and the main unit module 400 side by side, etc. This embodiment does not make specific limitations on it, and can be adaptively set according to actual needs.

[0077] It should be noted that the water storage module 200 is a component specifically for storing water, and its interior is made of food-grade stainless steel material or other materials that meet the drinking water safety standards to ensure the quality of the stored water and avoid secondary pollution. Its shape and capacity can be diversely designed according to the overall design of the water heater and market demands, such as cylindrical, cuboid, etc., and the capacity ranges from dozens of liters to hundreds of liters to adapt to different scenarios such as home and commercial use. The specific capacity and shape are not limited in this embodiment.

[0078] It should be noted that the host module 400 uses heat pump technology to heat the water in the water storage module 200. The heat pump cycle is mainly composed of four core components: a compressor, a condenser, an evaporator, and an expansion valve. The compressor is like the "heart" of the entire system. It compresses the gaseous refrigerant into a high-temperature and high-pressure state. At this time, the refrigerant carries a large amount of heat energy; then, the high-temperature and high-pressure refrigerant enters the condenser, which is usually tightly fitted with the water storage module 200 or connected through a heat exchange pipe. The refrigerant releases heat to the water in the water storage module 200 in the condenser, raising the water temperature, and the refrigerant itself condenses into a liquid state; the liquid refrigerant then passes through the expansion valve, which plays a role in throttling and reducing pressure, causing the refrigerant pressure and temperature to drop sharply, becoming a low-temperature and low-pressure liquid and entering the evaporator; in the evaporator, the refrigerant absorbs the heat of the external environment (this embodiment uses geothermal heat) and evaporates and vaporizes, turning into a gaseous state again to prepare for the next cycle. This cycle is repeated, and the heat in the environment is continuously transported to the water to achieve water heating.

[0079] Integrated and detachable connection design: The main unit module 400 and the water storage module 200 are integrated in the water heater housing 100. This integrated design makes the entire water heater structure more compact, reduces the connection gaps and exposed parts between components, and is not only beautiful, but also reduces heat loss and reduces the risk of failure. The main unit module 400 is located at the first end of the water heater housing 100, and the water storage module 200 is located at the second end. The two are connected by a detachable connection structure. The detachable connection structure facilitates the maintenance, inspection and replacement of components of the equipment. For example, when a heat pump component of the main unit module 400 fails, there is no need to disassemble the entire water heater. The main unit module 400 can be taken out separately for repair by simply disassembling the connection structure, which greatly improves the efficiency of after-sales maintenance. Common detachable connection structures include snap-on type and magnetic type. The snap-on connection structure uses cleverly designed plastic or metal snaps to tightly fix the main unit and the water storage module 200. During disassembly, only pressing or flicking a specific snap can separate them. The magnetic connection uses the adsorption characteristics of a strong magnet to make the connection process more convenient and quick, and can ensure a certain connection stability.

[0080] The temperature detection module is responsible for accurately detecting the first water temperature value before heating and the second water temperature value after heating of the auxiliary heating module 300, and providing corresponding temperature data for the intelligent control of the entire water heater. The temperature detection module is composed of high-precision temperature sensors, and the specific temperature sensor types include thermistor type, thermocouple type, etc., which are not specifically limited. The temperature sensors are installed at the water inlet and outlet of the auxiliary heating module 300 respectively, which can sense the temperature changes of the water flow at different stages in real time and accurately, and transmit the detected temperature signals to the control module in the form of electrical signals.

[0081] Based on the first water temperature value and the second water temperature value transmitted by the temperature detection module, the control module uses the built-in intelligent control strategy and algorithm to precisely control the first working mode of the host module 400 and the auxiliary heating module 300. The control logic is as follows:

[0082] When the first water temperature value is close to the target water temperature (the target water temperature depends on different water usage scenarios set by the user or preset by the water heater, such as the bathing water temperature is generally between 38 - 42 °C), and the second water temperature value has reached the target water temperature, it indicates that the current hot water supply state is good. The control module will instruct the host module 400 to operate at low power to maintain the stability of the water temperature in the water storage module 200, and at the same time turn off the auxiliary heating module 300 to achieve the purpose of energy saving. For example, in spring and autumn seasons when the ambient temperature is relatively suitable and the heat pump heating efficiency of the host module 400 is high, when the detected first water temperature value is 39 °C, the second water temperature value is 40 °C, and the user-set bathing water temperature is 40 °C, the host module 400 will reduce the operating frequency of the compressor and continuously operate at low power, and the auxiliary heating module 300 stops working.

[0083] If the first water temperature value is lower than the target water temperature, but the second water temperature value has reached the target water temperature, this indicates that the auxiliary heating module 300 effectively makes up for the insufficient heating of the host module 400. At this time, the control module will appropriately increase the power of the host module 400 to make the host module 400 speed up the heating speed of the water in the water storage module 200, and at the same time reduce the power of the auxiliary heating module 300 to reduce its energy consumption, making the two work together more efficiently and energy-saving. For example, in the colder winter weather, the first water temperature value after the initial heating of the host module 400 is 32 °C, and the second water temperature value reaches 40 °C after being increased by the auxiliary heating module 300. The control module will increase the compressor power of the host module 400 and at the same time reduce the resistance wire heating power of the auxiliary heating module 300.

[0084] When both the first water temperature value and the second water temperature value are lower than the target water temperature, it means that the water temperature of the current hot water supply is seriously insufficient and needs to be quickly heated up. The control module will immediately increase the power of the host module 400 and the auxiliary heating module 300, so that the host module 400 fully absorbs heat from the environment through the heat pump cycle, and the auxiliary heating module 300 also operates at the maximum power to quickly raise the water temperature to the target value. For example, on a cold winter morning, the user urgently needs a large amount of hot water for bathing, and the initially detected first water temperature value is only 25 °C and the second water temperature value is 30 °C. The control module will simultaneously increase the power supply of the compressor of the host module 400 and the resistance wire of the auxiliary heating module 300 to produce hot water at the fastest speed.

[0085] If the first water temperature value is higher than the target water temperature, the control module will reduce the power of the main unit module 400 to prevent the water temperature from rising further. If the second water temperature value is too high at this time, even exceeding the safe or comfortable water temperature range, the control module will also control the auxiliary heating module 300 to stop working, or start the corresponding cooling device (if equipped) to cool the water flow to ensure that the outlet water temperature is appropriate. For example, in summer, when the ambient temperature is high, the heat pump heating of the main unit module 400 may cause the water temperature to be too high. When the first water temperature value is detected to be 45°C and the second water temperature value is 50°C, while the user-set washing water temperature is 35°C, the control module will reduce the operating frequency of the compressor of the main unit module 400 and stop the auxiliary heating module 300 from working. If the water temperature still cannot be lowered, the control module can also reverse the running direction of the refrigerant by starting the compressor of the main unit module 400 to dissipate heat and cool the outlet water.

[0086] The control module continuously monitors the changes in the first water temperature value and the second water temperature value, and dynamically adjusts parameters such as the power and operating time of the main unit module 400 and the auxiliary heating module 300 according to the real-time fluctuations of the water temperature. It can adapt to the changes in the ambient temperature, the fluctuations in the user's water flow, and the demand differences in different water usage periods, and always provide the user with hot water at a stable and appropriate temperature. For example, during the water usage process, if cold water suddenly mixes into the water storage module 200, resulting in a decrease in the first water temperature value, the control module will quickly detect this change and timely adjust the working states of the main unit module 400 and the auxiliary heating module 300 according to the difference between the current and target water temperatures to ensure that the outlet water temperature is not greatly affected.

[0087] Through the coordinated work of the above-mentioned modules, the integrated heat pump water heater can efficiently and intelligently meet the user's hot water needs in different environments and usage scenarios, ensuring both the timeliness and stability of hot water supply, and taking into account the requirements of energy conservation and intelligent control.

[0088] In some alternative embodiments, the detachable connection structure includes: a slide rail provided on the inner wall of the water heater housing 100; a slider provided on the main unit module 400, and the slider is adapted to the slide rail; a locking device provided on the water heater housing 100 for locking the main unit module 400 in the water heater housing 100; an unlocking device for unlocking the locking of the locking device.

[0089] It should be noted that the sliding rail is arranged on the inner wall of the water heater housing 100 and is an orbital structure with specific shapes and specifications. The sliding rail is usually made of high-strength and wear-resistant metal materials (such as stainless steel) to ensure that it can bear the weight of the main engine module 400 and the friction during daily use. The shape of the sliding rail can be linear, which is convenient for the installation and disassembly operations of the main engine module 400 along a specific direction. Its surface is smooth-treated to reduce the resistance when the slider slides on it, making the installation and disassembly processes smoother.

[0090] The slider is installed on the main engine module 400 and is adapted to the sliding rail. The material of the slider is also usually selected as wear-resistant and low-friction coefficient materials, such as engineering plastics or metals with special surface treatments. The shape of the slider fits the grooves or protrusions of the sliding rail and can be tightly embedded in the sliding rail to ensure that there is no deviation or shaking during the sliding process. When installing the main engine module 400, just align the slider with the sliding rail and then push the main engine module 400 along the sliding rail to smoothly install it into the water heater housing 100; conversely, when disassembling, slide the main engine module 400 in the reverse direction along the sliding rail.

[0091] The locking device is arranged on the water heater housing 100 and is used to lock the main engine module 400 inside the water heater housing 100. Common locking devices can be snap-type, bolt-nut type or magnetic attraction type, etc., and are not specifically limited here. For example, the snap-type locking device consists of a hook fixed on the water heater housing 100 and a slot arranged at the corresponding position of the main engine module 400; when the main engine module 400 slides to the appropriate position through the sliding rail, the hook will automatically be embedded in the slot to achieve the locking of the main engine module 400. The bolt-nut type locking device is to fasten the two together by using bolts and nuts through the installation holes reserved on the water heater housing 100 and the main engine module 400. The magnetic attraction type locking device uses the attraction of the magnet to firmly fix the main engine module 400 inside the water heater housing 100. The main function of the locking device is to ensure that the main engine module 400 will not be displaced or loosened due to factors such as vibration and external forces during the operation of the water heater. It can ensure the connection stability between the main engine module 400 and the water storage module 200, as well as the relative position relationship between each component, thus ensuring the normal operation and stable performance of the water heater.

[0092] The unlocking device is used to release the lock of the locking device. For different types of locking devices, the working methods of the unlocking device are also different. For the snap - type locking device, the unlocking device can be a button or a toggle. When the button is pressed or the toggle is toggled, the hook will disengage from the slot, thus releasing the lock. For the bolt - nut type locking device, the unlocking device can be a tool such as a screwdriver, which is used to loosen the bolts to achieve the disassembly of the host module 400. For the magnetic - attraction type locking device, the unlocking device can be an electromagnetic switch. When powered on, it generates a magnetic field opposite to the original magnetic force, cancels the attraction of the magnet, and enables the host module 400 to be easily disassembled.

[0093] Installation process: First, align the slider on the host module 400 with the slide rail on the inner wall of the water heater housing 100. Then, slowly push the host module 400 along the slide rail so that it gradually enters the water heater housing 100. When the host module 400 reaches the predetermined position, use the locking device to lock it in the water heater housing 100. For example, if it is a snap - type locking device, the hook will automatically engage in the slot; if it is a bolt - nut type locking device, use a screwdriver to tighten the bolts.

[0094] Disassembly process: Operate the unlocking device to release the lock of the locking device on the host module 400. For example, press the unlocking button of the snap - type locking device, or use a screwdriver to loosen the bolts of the bolt - nut type locking device. Slide the host module 400 in the reverse direction along the slide rail and take it out of the water heater housing 100.

[0095] The detachable connection structure has the advantages of convenient installation and disassembly, low maintenance cost, and firm connection. It greatly improves the maintainability and upgradability of the water heater, reduces the difficulty and cost of after - sales maintenance. At the same time, due to the firm connection, it can ensure the performance stability of the water heater during long - term use.

[0096] In some alternative embodiments, a locking mechanism is provided on the slider, and the locking mechanism is used to lock the host module 400 on the slider.

[0097] It should be noted that setting the locking mechanism on the slider further enhances the firmness and reliability of the connection between the host module 400 and the slider. The host module 400 will generate certain vibrations during operation, especially when the compressor in the heat pump circulation system is running, the vibration is more obvious. If the connection between the host module 400 and the slider is not firm enough, long - term vibration may cause loosening, displacement, etc. between the host module 400 and the slider, which will affect the normal operation of the entire water heater and may even cause damage to the connecting components. The locking mechanism can effectively prevent this situation from occurring, ensure the fixed position of the host module 400 on the slider, and guarantee the stable performance of the water heater.

[0098] In some embodiments, with reference to Figure 3 , the auxiliary heating module 300 includes: an instant heating pipe 320 for heating the water flowing through the auxiliary heating pipe 310, and the instant heating pipe is arranged inside the auxiliary heating pipe 310; a flow sensor for detecting the water flow information of the water flowing through the auxiliary heating pipe 310; and the control module is further configured to control the working mode of the instant heating pipe 320 after receiving the water flow information of the flow sensor.

[0099] It should be noted that multiple instant heating pipes are provided in the present application, and the heating power of one or more instant heating pipes can be controlled according to specific heating requirements, so as to meet the heating requirements in various situations.

[0100] The instant heating pipe 320 can instantaneously heat the water flow. A high-power resistance wire is used as the heating element. When an electric current passes through the resistance wire, the resistance wire will quickly generate heat, efficiently convert electrical energy into heat energy, and transfer the heat to the water flowing through the auxiliary heating pipe 310 through heat conduction, so that the water flow can be heated up in a very short time to meet the user's demand for quickly obtaining hot water. Arranging the instant heating pipe 320 inside the auxiliary heating pipe 310 can ensure that the heat is directly and efficiently transferred to the water flow. This closely fitting layout reduces heat loss, making almost all of the heat energy absorbed by the water, further improving the heating efficiency. At the same time, the material of the auxiliary heating pipe 310 is selected as a metal material with good thermal conductivity, such as stainless steel or copper pipe, which can quickly and evenly disperse the heat generated by the instant heating pipe 320 into the water flow to ensure a uniform increase in water temperature.

[0101] The flow sensor is responsible for accurately detecting the water flow information of the water flowing through the auxiliary heating pipe 310. The flow detection is realized by using the electromagnetic induction principle, the turbine measurement principle, etc. Taking the electromagnetic induction principle as an example, when the water flow passes through the magnetic field inside the sensor, an induced electromotive force will be generated, and the magnitude of the electromotive force is proportional to the water flow. The flow sensor can accurately calculate the magnitude of the water flow by detecting this electromotive force. The turbine flow sensor uses the water flow to drive the internal turbine to rotate and calculates the water flow by detecting the rotation speed of the turbine. The specific flow sensor is not limited here. Different water flows mean that the amount of water to be heated per unit time is different, which in turn affects the heating power requirement of the instant heating pipe 320. For example, when the user opens the hot water faucet and the water flow is large, the instant heating pipe 320 needs to quickly provide more heat to ensure that the water flowing out reaches the set temperature; when the water flow is small, the power of the heating pipe is correspondingly reduced to avoid energy waste.

[0102] When the control module receives the information of a large water flow from the water flow sensor, it will immediately control the instant heating pipe 320 to increase its working power through a control instruction. Since a large flow of water needs to absorb more heat in a short time to reach the target temperature, the control module will increase the supply current to the heating pipe, so that its heating power increases. For example, when the user turns on multiple hot water outlets at the same time, such as when the kitchen sink and the bathroom shower are discharging water simultaneously, the water flow sensor detects a large flow, and the control module will drive the instant heating pipe 320 to operate at a high power to ensure that the water flowing out everywhere can maintain an appropriate temperature. On the contrary, when the water flow is small, the control module will reduce the working power of the instant heating pipe 320, which can not only meet the heating requirements of small-flow water, but also avoid problems such as energy waste caused by overheating and too high water temperature. For example, when the user only turns on the faucet in the bathroom sink and the water flow is small, the instant heating pipe 320 only needs to operate at a low power to heat the water to a suitable temperature.

[0103] The control module not only controls the instant heating pipe 320 based on the water flow, but also comprehensively considers the water temperature information transmitted by the temperature detection module. If the water flow is large and the water temperature before auxiliary heating is low, in addition to increasing the power of the heating pipe, the control module will also extend the heating time and / or increase the power of the compressor in the host module 400 to ensure that the water flowing out reaches the set temperature.

[0104] Through the coordinated work of the instant heating pipe 320, the water flow sensor and the control module, the auxiliary heating module 300 can quickly provide hot water at an appropriate temperature in various water usage scenarios. Whether the user urgently needs a large amount of hot water for bathing or only needs a small amount of hot water for washing hands, the system can accurately adjust according to the actual water flow and water temperature conditions to ensure that the hot water is available immediately, greatly improving the user experience.

[0105] Dynamically adjusting the power of the instant heating pipe 320 according to the water flow avoids unnecessary energy consumption. Reducing the power when the water flow is small or the water temperature is close to the target temperature, and increasing the power when the water flow is large and the water temperature is low, enables the water heater to save electricity to the greatest extent while meeting the user's hot water demand, achieving a perfect combination of high energy efficiency and precise temperature control.

[0106] The water usage habits of different users vary greatly at different times. Some families may often use multiple hot water outlets simultaneously, while others mainly use a small amount of water for a single person. This intelligent control strategy based on water flow information enables the auxiliary heating module 300 to flexibly adapt to various diverse water usage requirements and provide stable and comfortable hot water services for users.

[0107] In some alternative embodiments, refer to Figure 4, the host module 400 includes a first heat exchange component 410, a second heat exchange component 420, and a compressor component 430. The first heat exchange component 410 is respectively connected to a geothermal water inlet pipe 411, a geothermal water outlet pipe 412, a first refrigerant input pipe 414, and a first refrigerant output pipe 413. The second heat exchange component 420 is respectively connected to a heating water inlet pipe 422, a heating water outlet pipe 421, a second refrigerant input pipe 423, and a second refrigerant output pipe 424;

[0108] The geothermal water inlet pipe 411 is used to transport the geothermal water heated by the earth into the first heat exchange component 410. The compressor component 430 is used to transport the first refrigerant from the first refrigerant input pipe 414 into the first heat exchange component 410, so that the geothermal water heats the first refrigerant to obtain a second refrigerant. The geothermal water outlet pipe 412 is used to transport the cooled geothermal water in the first heat exchange component 410 back to the earth for heating;

[0109] The first refrigerant output pipe 413 is used to transport the second refrigerant to the second refrigerant input pipe 423, and the second refrigerant input pipe 423 is used to transport the second refrigerant into the second heat exchange component 420. The heating water inlet pipe 422 is used to transport the water to be heated into the second heat exchange component 420, so that the water to be heated is heated to obtain once-heated water during the phase change of the second refrigerant into the first refrigerant. The heating water outlet pipe 421 is used to transport the once-heated water to the auxiliary heating module 300. The second refrigerant output pipe 424 is used to transport the first refrigerant in the second heat exchange component 420 to the first refrigerant input pipe 414.

[0110] It should be noted that the first heat exchange component 410, as the front-end heat exchange unit of the entire heat pump cycle system, is respectively connected to the geothermal water inlet pipe 411, the geothermal water outlet pipe 412, the first refrigerant input pipe 414, and the first refrigerant output pipe 413. The geothermal water inlet pipe 411 introduces the geothermal water heated by the earth deep in the earth into the first heat exchange component 410, providing a stable high-temperature heat source for subsequent heat exchange. The geothermal water outlet pipe 412 is responsible for transporting the geothermal water that has completed heat exchange with the refrigerant and has a reduced temperature in the first heat exchange component 410 back to the earth so that it can be heated by the geothermal energy again, forming a sustainable geothermal water recycling system.

[0111] Heat exchange principle: When high-temperature geothermal water flows through the first heat exchange component 410, at the same time, the compressor component 430 drives the first refrigerant to enter the component from the first refrigerant input pipe 414. Since the geothermal water temperature is higher than the initial temperature of the refrigerant, according to the heat transfer principle, the heat will be spontaneously transferred from the geothermal water to the refrigerant, so that the refrigerant absorbs the heat and undergoes a phase change, from a low-temperature and low-pressure state to a high-temperature and high-pressure second refrigerant. In this process, the temperature of the geothermal water gradually decreases, and the refrigerant is effectively heated.

[0112] The second heat exchange component 420 is similar to the first heat exchange component 410 in terms of the pipe connection method. It is respectively connected to the heating water inlet pipe 422, the heating water outlet pipe 421, the second refrigerant input pipe 423 and the second refrigerant output pipe 424. The heating water inlet pipe 422 introduces the water to be heated from the water storage module 200 or other water sources into the second heat exchange component 420, where the water to be heated will become the receptor for receiving thermal energy. The second refrigerant input pipe 423 receives the high-temperature and high-pressure second refrigerant output from the first heat exchange component 410. When the second refrigerant enters the second heat exchange component 420, the heat is transferred again because its temperature is higher than the water to be heated.

[0113] Realize secondary heat exchange: In the second heat exchange component 420, the second refrigerant gradually changes into the low-temperature and low-pressure first refrigerant in the process of releasing heat to the water to be heated. This phase change process is accompanied by the release of a large amount of heat, which can efficiently heat the water to be heated and convert it into primary heating water. The heating water outlet pipe 421 then transports the primary heating water to the auxiliary heating module 300. If the temperature of the primary heating water meets the use requirements, the auxiliary heating module 300 can choose not to work or make fine adjustments according to the actual situation; if the water temperature still does not meet the standard, the auxiliary heating module 300 will further increase the water temperature. Finally, the second refrigerant output pipe 424 will return the refrigerant that has completed the heat exchange task and has been converted back to the first refrigerant to the first refrigerant input pipe 414, and re-enter the heat pump cycle.

[0114] Initial heat exchange between geothermal water and refrigerant: As a huge natural heat source, the earth contains abundant geothermal energy. The geothermal water inlet pipe 411 continuously transports relatively high-temperature geothermal water to the first heat exchange component 410. At the same time, the compressor component 430 drives the first refrigerant into the same component. Inside the first heat exchange component 410, geothermal water and refrigerant transfer heat through the special heat exchange pipe wall. Since the temperature of geothermal water is usually tens of degrees Celsius, which is much higher than the initial refrigerant temperature, the refrigerant quickly absorbs heat, the temperature rises and phase changes, forming a high-temperature and high-pressure second refrigerant. The geothermal water cools down after releasing heat, and flows back to the earth through the geothermal water outlet pipe 412 to be reheated.

[0115] Generation and transportation of primary heated water: The high-temperature and high-pressure secondary refrigerant obtained from the initial heat exchange is transported to the second heat exchange component 420 through the first refrigerant output pipeline 413 and the second refrigerant input pipeline 423. At this time, the water to be heated from the water storage module 200 enters the second heat exchange component 420 through the heated water inlet pipeline 422, forming a temperature difference with the secondary refrigerant, and the heat is transferred from the refrigerant to the water to be heated again. In this process, the secondary refrigerant gradually loses heat and phase-changes back to the low-temperature and low-pressure primary refrigerant, while the water to be heated absorbs heat and is heated to become primary heated water with a slightly increased temperature. The heated water outlet pipeline 421 transports the primary heated water to the auxiliary heating module 300, and the auxiliary heating module 300 decides whether to further heat the primary heated water according to the instructions of the control module, considering factors such as the current water temperature, flow rate, and user requirements.

[0116] After completing the heat exchange in the second heat exchange component 420 and phase-changing back to the primary refrigerant, it is sent back to the first refrigerant input pipeline 414 through the second refrigerant output pipeline 424, waiting to be compressed again by the compressor component 430, thus forming a complete and continuous refrigerant circulation loop. Throughout the process, heat is extracted from the geothermal water in the ground, undergoes two heat exchanges, and finally is transferred to the water to be heated, meeting the user's demand for hot water, with significant energy-saving and environmental protection advantages.

[0117] In some embodiments, referring to Figure 5 , the heated water inlet pipeline 422 includes a first branch pipe, a second branch pipe, and a first main pipe. The first branch pipe is used to transport the externally connected water to be heated to the first end of the first main pipe, the second branch pipe is used to transport the water to be heated from the water storage module 200 to the first end of the first main pipe, and the second end of the first main pipe is used to transport the water to be heated to the second heat exchange component 420; a hot water transportation pipeline 311 is provided between the auxiliary heating module 300 and the water storage module 200, and the hot water transportation pipeline 311 is used to transport the secondary heated water heated by the auxiliary heating module 300 to the water storage module 200 and / or the externally connected water pipeline.

[0118] Specifically, the heated water inlet pipeline 422 is composed of a first branch pipe, a second branch pipe, and a first main pipe. The first branch pipe is connected to an external water source, such as a municipal water supply pipeline, and it can transport the externally connected normal-temperature water to be heated to the first end of the first main pipe. The second branch pipe is connected to the water storage module 200, and the water storage module 200 stores water that has been partially treated or preliminarily heated before. Similarly, it can be transported to the first end of the first main pipe through the second branch pipe, so as to re-transport the water in the water storage module 200 to the second heat exchange component 420 and the auxiliary heating module 300 for re-heating.

[0119] In some embodiments, at the first end of the first main pipe, the water to be heated from the external water source and the water storage module 200 is mixed, and the initial temperature and the amount of the water to be heated entering the second heat exchange component 420 can be flexibly adjusted according to the actual situation. For example, when the temperature of the external water source is relatively low and there is excess water in the water storage module 200, the amount of water introduced from the water storage module 200 can be appropriately increased to raise the initial temperature of the water to be heated after mixing, thereby reducing the energy consumption in the subsequent heating process. The water to be heated after mixing is conveyed to the second heat exchange component 420 through the second end of the first main pipe, and heat exchange is performed with the high-temperature refrigerant in the second heat exchange component 420 to achieve preliminary heating, and secondary heating is performed through the auxiliary heating module 300, so as to meet the water usage requirements.

[0120] Referring to Figure 5 , the hot water delivery pipe 311 provided between the auxiliary heating module 300 and the water storage module 200 plays a role in hot water circulation and supply. After the auxiliary heating module 300 further heats the primary heated water from the second heat exchange component 420, the secondary heated water with a higher temperature is obtained. The secondary heated water has two flow directions after passing through the hot water delivery pipe 311: on the one hand, part of the secondary heated water can be conveyed back to the water storage module 200, which helps to increase the overall temperature of the water in the water storage module 200, enabling the water storage module 200 to store more hot water to meet the subsequent water usage requirements. For example, during the low water usage period, the heated hot water is sent back to the water storage module 200 for storage for use during the peak period. On the other hand, the secondary heated water can also be directly conveyed to the external water use pipe through the hot water delivery pipe 311 to provide instant hot water supply to users. Specifically, the multi-way valve 312 on the hot water delivery pipe 311 controls the delivery of the secondary hot water to the external water use pipe and the water storage module 200. Through the flexible delivery method, it can be adjusted according to the actual water usage situation. Whether it is a scenario where a large amount of hot water is needed in a short time or a scenario with special requirements for the hot water temperature, the user's needs can be met in a timely manner. For example, when a user needs to take a hot bath, the secondary heated water can be directly conveyed to the bathroom through the external water use pipe to ensure the instant supply and appropriate temperature of the hot water.

[0121] The combination of the multi-source introduction of the heating water inlet pipe 422 and the flexible delivery method of the hot water delivery pipe 311 enables the entire hot water machine system to be flexibly adjusted according to different working conditions and user requirements. By reasonably adjusting the water inflow of the first branch pipe and the second branch pipe, the initial state of the water to be heated can be optimized, and unnecessary energy consumption can be reduced. At the same time, the hot water circulation and direct supply functions can ensure that hot water with an appropriate temperature and amount can be efficiently provided at any time, improving the energy utilization efficiency and the user experience.

[0122] The control module can precisely control the valve openings of the first branch pipe and the second branch pipe based on the water temperature information detected by the temperature detection module, the water flow information detected by the flow sensor, and the water usage requirements set by the user, so as to achieve the optimal mixing ratio of the water to be heated. At the same time, the control module can also decide whether to transport the secondary heated water back to the water storage module 200 or directly supply it to the external water usage pipeline according to the water level and water temperature conditions in the water storage module 200, further optimizing the operation efficiency of the system.

[0123] By continuously monitoring and analyzing the operation data of the system, the control module can continuously optimize the entire hot water machine system. For example, according to the external environmental temperature and water usage patterns in different seasons and different time periods, automatically adjust the heating strategy and hot water delivery method to achieve the best energy-saving effect and user satisfaction.

[0124] In some alternative embodiments, the heat pump water heater further includes an interaction module, and the interaction module is used to obtain water usage type information, environmental temperature information, and water usage preference information;

[0125] The control module is further used for:

[0126] Determine a first target water temperature according to the water usage type information and the environmental temperature information;

[0127] Obtain a second target water temperature after correcting the first target water temperature according to the water usage preference;

[0128] Control the second working modes of the main machine module 400 and the auxiliary heating module 300 according to the second target water temperature, the first water temperature value, and the second water temperature value.

[0129] It should be noted that the interaction module can collect water usage type information in various ways. For example, through the intuitive buttons set on the operation panel of the water heater, before using hot water, the user can press the corresponding buttons such as "showering", "washing face", "kitchen water use" according to actual needs, accurately informing the water heater of the water usage scenario, or obtain the voice information of the user through a voice acquisition device, and then identify the corresponding water usage requirements to obtain the corresponding water usage type information. For the environmental temperature information, the interaction module can be equipped with a high-precision temperature sensor built-in or set on the shell to sense the temperature of the surrounding environment where the water heater is located in real time. The water usage preference information can be obtained through the touch slider, star rating on the operation panel, or simple text description options (such as "prefer hotter", "moderate temperature", "like slightly warm", etc.), or extracted from the user's historical water usage information to obtain the corresponding water usage preference.

[0130] Through diversified information collection methods, the user experience has been greatly improved. On the one hand, users can quickly convey their needs to the water heater without complex operations or professional knowledge. On the other hand, the hot water service provided by the water heater based on this accurate information better meets the user's wishes.

[0131] The control module determines the first target water temperature based on the pre-stored big data model, combined with the water usage type information input by the user through the interaction module and the ambient temperature information collected in real time. Taking bathing water as an example, in the cold winter, when the ambient temperature is low, the human body dissipates heat quickly. To ensure a comfortable bathing experience, the control module sets the first target water temperature in a relatively high range, such as 40-42°C, according to empirical data. In the hot summer, the ambient temperature is high, and the required water temperature for the human body relatively decreases. At this time, the first target water temperature will be set at 37-39°C. For kitchen water, since it is mainly used for washing dishes, the water temperature generally does not need to be too high, and the first target water temperature usually stabilizes at 30-35°C.

[0132] After determining the first target water temperature, the control module further fine-tunes the water temperature considering the user's water usage preference information. If the user selects "prefer hotter", the control module will appropriately increase the temperature by 1-3°C based on the first target water temperature. If the user prefers "moderate temperature", the first target water temperature will basically remain unchanged. If the user likes "lukewarm", the water temperature will be correspondingly decreased by 1-2°C to obtain the second target water temperature that precisely meets the user's personalized needs. Or, based on the user's historical water usage data, the user's water usage preference is determined, and then the first target water temperature is fine-tuned to obtain the second target water temperature. This hierarchical and dynamic water temperature determination mechanism fully considers the individual differences of users and makes the hot water supply more user-friendly.

[0133] The control module uses corresponding algorithms to precisely regulate the second working modes of the main unit module 400 and the auxiliary heating module 300 according to the determined second target water temperature, as well as the first water temperature value before heating and the second water temperature value after heating feedback by the temperature detection module for the auxiliary heating module 300. When the first water temperature value is close to the second target water temperature and the second water temperature value has reached or is slightly higher than the second target water temperature, it indicates that the current hot water supply state is good. The control module will instruct the main unit module 400 to maintain operation at a low power to ensure the water temperature is stable, and at the same time turn off the auxiliary heating module 300 to avoid energy waste. For example, in spring and autumn, the ambient temperature is suitable, and the heat pump heating efficiency of the main unit module 400 is high. If it is detected that the first water temperature value is 39°C, the second water temperature value is 40°C, and the second target water temperature set by the user for bathing is 40°C, the main unit module 400 will reduce the operating frequency of the compressor, and the auxiliary heating module 300 will stop working.

[0134] If the first water temperature value is lower than the second target water temperature, but the second water temperature value reaches the second target water temperature, this means that the auxiliary heating module 300 effectively makes up for the deficiency of the main engine module 400 in heating. At this time, the control module will appropriately increase the power of the main engine module 400 to accelerate the heating speed of the water in the water storage module 200, and at the same time reduce the power of the auxiliary heating module 300 to optimize the energy efficiency of their collaborative work. For example, in relatively cold winter weather, the first water temperature value after the initial heating of the main engine module 400 is 32 °C, and the second water temperature value reaches 40 °C after being increased by the auxiliary heating module 300. The second target water temperature for bathing set by the user is 40 °C. The control module will increase the compressor power of the main engine module 400 and at the same time reduce the resistance wire heating power of the auxiliary heating module 300.

[0135] When both the first water temperature value and the second water temperature value are lower than the second target water temperature, it means that the water temperature of the current hot water supply is seriously insufficient and needs to be quickly heated up. The control module will immediately increase the power of the main engine module 400 and the auxiliary heating module 300, so that the main engine module 400 fully absorbs heat from the environment through the heat pump cycle, and the auxiliary heating module 300 also operates at the maximum power to quickly raise the water temperature to the second target value. For example, on a cold winter morning, the user urgently needs a large amount of hot water for bathing. The initially detected first water temperature value is only 25 °C, the second water temperature value is 30 °C, and the second target water temperature for bathing set by the user is 40 °C. The control module will simultaneously increase the power supply of the compressor of the main engine module 400 and the resistance wire of the auxiliary heating module 300 to produce hot water at the fastest speed.

[0136] On the contrary, if the first water temperature value is higher than the second target water temperature, the control module will reduce the power of the main engine module 400 to prevent the water temperature from rising further. If the second water temperature value is too high at this time, exceeding the safe or comfortable water temperature range, the control module will also control the auxiliary heating module 300 to stop working, or start the compressor of the compression component to reverse the conveying direction of the refrigerant to cool the water flow to ensure that the outlet water temperature is appropriate; specifically, the compressor controls the conveying direction through the refrigerant diversion valve 431.

[0137] Through the close cooperation of the interaction module, the control module and other related components, the heat pump water heater can intelligently adapt to various complex water use scenarios and user needs, while ensuring the supply of comfortable hot water, achieving high efficiency and energy saving, and bringing a good user experience to users.

[0138] In some alternative embodiments, the interaction module includes a human-computer interaction unit, an environmental temperature detection unit, and a historical data unit. The human-computer interaction unit is used to obtain the water use type information, the environmental temperature detection unit is used to obtain the environmental temperature information, and the historical data unit is used to store the water use preference information.

[0139] Specifically, through the human-machine interaction unit, users can directly interact with the heat pump water heater. The human-machine interaction unit is equipped with an intuitive operation interface, such as a touch screen, physical buttons, or a voice interaction system, etc. Taking the touch screen as an example, before using hot water, users can select different water usage types, such as "bathing", "washing", "kitchen water use", "laundry", etc., by touching the icons or text options on the screen. For the design of physical buttons, dedicated function buttons will be set, and users can input water usage type information by pressing the corresponding buttons. The voice interaction system is even more convenient. Users only need to say instructions such as "I want to take a bath" or "Prepare hot water for washing dishes", and the system can accurately obtain the user's water usage type requirements through voice recognition technology.

[0140] The diverse interaction methods greatly enhance the user experience and meet the operation habits and needs of different users. Whether it is young users familiar with smart devices or elderly users accustomed to traditional operation methods, they can easily interact with the water heater, accurately convey their water usage intentions, enabling the water heater to provide appropriate hot water services according to different water usage types.

[0141] The ambient temperature detection unit is mainly composed of high-precision temperature sensors, such as thermistor temperature sensors or thermocouple temperature sensors. It can perceive the temperature changes in the environment where the water heater is located in real time and accurately. The control module will reasonably adjust the working modes and parameters of the main unit module 400 and the auxiliary heating module 300 according to the data provided by the ambient temperature detection unit, combined with the water usage type information. For example, in the cold winter, the ambient temperature is low, and the control module will appropriately increase the heating power of the main unit module 400 and start the auxiliary heating module 300 in advance to ensure that hot water with sufficient temperature can be provided quickly; while in the hot summer, the ambient temperature is high, and the control module will correspondingly reduce the heating power to avoid energy waste and excessive water temperature.

[0142] The historical data unit is a module dedicated to storing water usage preference information, usually using non-volatile memory, such as flash memory, etc. It can record the water usage preference settings of users in different time periods and different water usage scenarios, such as the water temperature preferences selected by users each time ("prefer hotter", "moderate temperature", "like slightly warm", or specific adjusted water temperature values, etc.), water usage time habits, water usage frequencies, etc. These data will be stored classified and corresponding indexes will be established so that the control module can quickly and accurately retrieve and call them.

[0143] By analyzing and learning the historical data, the control module can gradually understand the user's water usage habits and preferences, and achieve a more personalized hot water supply service. For example, according to the user's long-term bathing water usage preferences, when the user selects the "bathing" water usage type each time, the control module can automatically adjust the water temperature to the user's preferred temperature range without the user having to reset it each time, greatly improving the user's convenience and comfort of use.

[0144] The water usage type information obtained by the human - machine interaction unit, the ambient temperature information obtained by the ambient temperature detection unit, and the water usage preference information stored in the historical data unit are all transmitted to the control module in real - time. As the core control center of the entire water heater, the control module integrates and analyzes this information. According to the preset algorithms and logics, it determines the optimal hot - water supply strategy, including the adjustment of parameters such as the working modes, heating powers, and running times of the main machine module 400 and the auxiliary heating module 300.

[0145] During the operation of the water heater, information interaction and feedback continuously occur among the various units. For example, when the user's water usage preference changes, the human - machine interaction unit obtains the new preference information and transmits it to the historical data unit for updated storage. At the same time, the control module also adjusts the hot - water supply strategy according to the new preference information. The ambient temperature detection unit continuously monitors the change of the ambient temperature. Once the temperature fluctuates greatly, it promptly transmits the information to the control module, and the control module will dynamically optimize the operation of the main machine module 400 and the auxiliary heating module 300 accordingly to adapt to different environmental conditions and user demands.

[0146] Through the close collaborative work of the human - machine interaction unit, the ambient temperature detection unit, and the historical data unit, the interaction module provides rich and accurate information support for the heat - pump water heater, enabling the water heater to achieve intelligent and personalized hot - water supply, improving the user's usage experience and the operation efficiency of the water heater.

[0147] In some alternative embodiments, the historical data unit also stores the water usage preference information of different users. The voice acquisition unit acquires the user's voice information, obtains the identified user based on the voice information, and obtains the water usage preference of the identified user according to the voice information and / or other types of human - machine interaction information; when the voice acquisition unit acquires the water usage demand information of the identified user, the second target water temperature is adjusted according to the water usage preference of the identified user. Thus, it is possible to set appropriate water usage preferences for different users, avoiding the mutual influence of the water usage preferences of different users on the usage experience.

[0148] In some alternative embodiments, a water - level sensor and a water bucket are also arranged in the water storage module 200. The water bucket is used to store water, the water - level sensor is used to detect the water level in the water bucket, and the control module is also used to receive the signal of the water - level sensor and turn off the main machine module 400 when the water level is lower than the preset value.

[0149] Refer to Figure 6 , Figure 6 is a flowchart of the control method for an integrated heat - pump water heater provided by an embodiment of the present invention, which is applied to the integrated heat - pump water heater. Refer to Figure 2 - 5, the integrated heat pump water heater water storage module 200 includes a water storage module 200, a host module 400, an auxiliary heating module 300, a temperature detection module, and a control module. The host module 400 and the water storage module 200 are integrally arranged in the water heater housing 100. The host module 400 is located at the first end inside the water heater housing 100, and the water storage module 200 is located at the second end inside the water heater housing 100. The host module 400 is connected to the water storage module 200 through a detachable connection structure. The auxiliary heating module 300 is arranged on the water outlet path of the host module 400. The heat pump water heater further includes an interaction module. The control method of the integrated heat pump water heater according to the embodiments of the present invention may include, but is not limited to, steps S100, S200, S300, S400, S500, S600, S700, and S800.

[0150] Step S100, controlling, through the control module, the host module 400 to heat the water to be heated flowing into the water storage module 200 to obtain the first heated water.

[0151] Step S200, detecting, through the temperature detection module, the first water temperature value of the first heated water before being heated by the auxiliary heating module 300;

[0152] Step S300, obtaining, through the control module, a second water temperature value, where the second water temperature value represents the desired water temperature value after being heated by the auxiliary heating module 300;

[0153] Step S400, the control module controlling the first working modes of the auxiliary heating module 300 and the host module 400 according to the first water temperature value and the second water temperature value;

[0154] Step S500, obtaining, through the interaction module, water usage type information, environmental temperature information, and water usage preference information;

[0155] Step S600, the control module determining a first target water temperature according to the water usage type information and the environmental temperature information;

[0156] Step S700, the control module correcting the first target water temperature according to the water usage preference to obtain a second target water temperature;

[0157] Step S800, the control module correcting the first working modes of the host module 400 and the auxiliary heating module 300 according to the second target water temperature, the first water temperature value, and the second water temperature value to obtain a second working mode.

[0158] Specifically, the control module issues instructions to control the host module 400 to heat the water to be heated flowing into the water storage module 200. The host module 400 realizes heating through its internal heat pump cycle system. Specifically, the compressor assembly 430 first compresses the refrigerant with low temperature and low pressure into a gas with high temperature and high pressure. Then, the refrigerant with high temperature and high pressure enters the second heat exchange assembly 420, where the refrigerant with high temperature and high pressure is transformed into a refrigerant with low temperature and low pressure through the second heat exchange assembly 420, while heating the water to be heated, and the refrigerant with low temperature and low pressure is transported to the first heat exchange assembly 410 to exchange heat with the geothermal water flowing in from the geothermal water inlet pipe 411, absorbing the heat of the geothermal water. After that, the refrigerant with high temperature and high pressure enters the second heat exchange assembly 420 again, releasing the heat to the water to be heated, causing the water to be heated to rise in temperature and become the primary heated water. By utilizing geothermal energy and heat pump technology, an efficient and energy-saving heating method is achieved.

[0159] The temperature detection module detects the first water temperature value of the primary heated water before the auxiliary heating module 300 heats it. The temperature detection module is usually composed of high-precision temperature sensors, which can sense the change of water temperature in real time and accurately, and convert the detected temperature signal into an electrical signal and transmit it to the control module. The control module obtains the second water temperature value, which represents the desired water temperature value after the auxiliary heating module 300 heats. The determination of the second water temperature value is based on the preset parameters of the water heater system and the comprehensive consideration of different water usage scenarios and user requirements. For example, for bathing water, the preset desired water temperature is between 38°C and 42°C; for washing water, the desired water temperature is between 30°C and 35°C. The control module sets an appropriate second water temperature value according to different water usage types and other relevant factors, which is not specifically limited here.

[0160] The control module controls the first working mode of the auxiliary heating module 300 and the host module 400 according to the first water temperature value and the second water temperature value. Specifically, if the first water temperature value is close to the second water temperature value, it indicates that the preliminary heating effect of the host module 400 is good. At this time, the control module will reduce the power of the auxiliary heating module 300 or stop it from working, and at the same time maintain the host module 400 to operate at a low power to keep the water temperature stable and achieve the purpose of energy conservation. On the contrary, if the difference between the first water temperature value and the second water temperature value is large, the control module will increase the power of the auxiliary heating module 300 and at the same time adjust the working state of the host module 400 to accelerate the heating speed of the water to ensure that the desired water temperature can be quickly reached. The control method based on the water temperature value enables the water heater to flexibly adjust the working mode of the host module 400 and the auxiliary heating module 300 according to the actual water temperature situation, realizes precise temperature control, improves the efficiency and quality of hot water supply, and avoids waste of energy at the same time.

[0161] The interaction module is used to obtain water usage type information, environmental temperature information, and water usage preference information. The human-machine interaction unit obtains the water usage type information through the user's operations. For example, the user selects options such as "showering" or "washing" on the operation panel. The environmental temperature detection unit monitors the environmental temperature in real time and provides accurate environmental temperature data for the system. The historical data unit stores the user's water usage preference information, such as the preferred water temperature that the user is accustomed to.

[0162] The water usage type information determines the required temperature range of the hot water. Different water usage types have different requirements for the water temperature. The environmental temperature information affects the heating efficiency and energy consumption of the host module 400, as well as the water temperature range for use. For example, in a cold environment, the host module 400 needs to consume more energy to heat the water, and the water usage temperature needs to be increased accordingly. The water usage preference information reflects the user's personalized needs. The control module can fine-tune the water temperature according to the preference information to provide a more personalized hot water service.

[0163] The control module determines the first target water temperature based on the water usage type information and the environmental temperature information. The control module internally presets water temperature reference data under different water usage types and environmental temperatures. Through the analysis and calculation of these data, combined with the current actual situation, a suitable first target water temperature is determined. For example, in winter when the environmental temperature is low, the first target water temperature for showering water will be set higher; while in summer when the environmental temperature is high, the first target water temperature will be correspondingly reduced. Then, the control module corrects the first target water temperature according to the water usage preference information to obtain the second target water temperature. If the user prefers hotter water, the control module will appropriately increase the temperature based on the first target water temperature; if the user prefers cooler water, the temperature will be reduced.

[0164] The control module corrects the first working mode of the host module 400 and the auxiliary heating module 300 according to the second target water temperature, the first water temperature value, and the second water temperature value to obtain the second working mode. The control module will compare and analyze the second target water temperature with the first water temperature value and the second water temperature value, and adjust the working parameters of the host module 400 and the auxiliary heating module 300 according to the comparison results, such as the heating power and the running time. For example, if the second target water temperature is higher than the first water temperature value and the second water temperature value, the control module will increase the power of the host module 400 and the auxiliary heating module 300 to increase the water temperature; if the second target water temperature is lower than the current water temperature, the control module will reduce the heating power or stop heating to avoid the water temperature being too high.

[0165] Through the above control steps, the heat pump water heater can intelligently adjust the working modes of the host module 400 and the auxiliary heating module 300 according to different water usage scenarios, environmental conditions, and user preferences, realizing efficient, energy-saving, and personalized hot water supply, and enhancing the user's usage experience and satisfaction.

[0166] In some alternative embodiments, the control method further includes: establishing a first data table, a second data table, and a third data table through the control module; the control module looking up a water use temperature value in the first data table according to the water use type information, where the first data table indicates the correspondence between the water use type and the water use temperature; the control module looking up a first adjustment temperature value in the second data table according to the ambient temperature information, where the second data table indicates the correspondence between the first adjustment temperature values of different water use types and the ambient temperature; the control module looking up a second adjustment temperature value in the third data table according to the water use preference information, where the third data table indicates the correspondence between the second adjustment temperature values of different water use types and the water use preference; the control module adjusting the water use temperature value according to the first adjustment temperature value and the second adjustment temperature value to obtain the second target water temperature.

[0167] Specifically, the control module establishes a first data table, a second data table, and a third data table for storing and managing the correspondence between different factors to achieve precise control of the operation of the water heater.

[0168] First data table: It records the correspondence between the water use type and the water use temperature. For example, the water use temperature corresponding to "showering" is 40°C, the water use temperature corresponding to "washing face and brushing teeth" is 35°C, the water use temperature corresponding to "kitchen water use" is 30°C, etc. The specific water use types and water use temperatures are set according to actual needs and are not limited here. The base temperature value of the first data table is preset according to factors such as common water use needs and human comfort.

[0169] Second data table: Indicates the correspondence between the first adjustment temperature values of different water use types and the ambient temperature. For different water use types at different ambient temperatures, the required hot water temperature needs to be adjusted. For example, when the ambient temperature is low in winter, the first adjustment temperature value for "showering" water is +5°C to ensure that users can obtain warmer hot water; while when the ambient temperature is high in summer, the first adjustment temperature value for "showering" water is -6°C. The specific first adjustment temperature values are not limited here.

[0170] Third data table: Records the correspondence between the second adjustment temperature values of different water use types and the water use preference. Each user has different preferences for hot water. Some users like hotter water, and some users like moderate water temperature. If the user selects "prefer hotter", for "showering" water, the second adjustment temperature value is +3°C; if the user selects "moderate temperature", the second adjustment temperature value is 0°C, etc. The specific second adjustment temperature values are not limited here.

[0171] Finding the water usage temperature value: The control module looks up the corresponding water usage temperature value in the first data table according to the water usage type information obtained from the interaction module. For example, when the user selects the "showering" water usage type, the control module finds the water usage temperature value corresponding to "showering" in the first data table, which is assumed to be 40 °C.

[0172] Finding the first adjusted temperature value: Next, the control module looks up the first adjusted temperature value corresponding to this water usage type in the second data table according to the ambient temperature information obtained by the ambient temperature detection unit. If the current ambient temperature is in the low temperature range in winter, for the "showering" water usage, the first adjusted temperature value found from the second data table is +5 °C.

[0173] Finding the second adjusted temperature value: Finally, the control module looks up the second adjusted temperature value corresponding to this water usage type in the third data table according to the user's water usage preference information. If the user's water usage preference is "preferring hotter", for the "showering" water usage, the second adjusted temperature value found from the third data table is +3 °C.

[0174] The control module adjusts the water usage temperature value according to the found first adjusted temperature value and second adjusted temperature value, so as to obtain the second target water temperature. Taking the "showering" water usage as an example, the water usage temperature value is 40 °C, the first adjusted temperature value is +5 °C, and the second adjusted temperature value is +3 °C. Then the second target water temperature is 40 °C + 5 °C + 3 °C = 48 °C.

[0175] The method of determining the second target water temperature by establishing a data table and looking up the corresponding values enables the heat pump water heater to comprehensively consider various factors such as water usage type, ambient temperature, and user preference, and provide more accurate and personalized hot water services for users. At the same time, the data table method facilitates data management and update. If it is necessary to adjust parameters according to factors such as usage habits in different regions or seasonal changes, only the corresponding values in the data table need to be modified, which improves the flexibility and maintainability of the system.
