[0053] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," "in contact," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0054] When bathing in a low or high temperature environment, the temperature in the bathroom will be relatively high or low, which makes the comfort level poor. Users need to adjust the warm air or cold air to change the temperature in the bathroom during bathing. Therefore, they need to wait in the bathroom for a certain period of time before bathing, which is quite inconvenient.

[0055] Based on this, the following embodiments are proposed.

[0056] Example 1:

[0057] like Figure 1 As shown, this embodiment provides a water heater system for a bathroom, comprising:

[0058] The water tank 1 is provided with a through cavity 14 communicating with the bathroom;

[0059] The outlet pipe section 2 and the inlet pipe section 3 are connected to the water tank 1, and the outlet pipe section 2 is provided with an outlet valve 4, and the inlet pipe section 3 is connected to the water tank 1, and the inlet pipe section 3 is provided with an inlet valve 5;

[0060] The output pipe section 13 is connected to the water outlet pipe section 2;

[0061] The air supply pipe section 6 has a first air supply end 601 and a second air supply end 602 , wherein the first air supply end 601 is connected to the output pipe section 13 , and the second air supply end 602 is connected to the through cavity 14 ;

[0062] The heat pump unit 9 is used to provide hot air or cold air to the gas supply pipe section 6;

[0063] The heat pump section 9, the air supply pipe section 6, and the output pipe section 13 are designed as follows:

[0064] In the heating state, the heat pump unit 9 can provide hot air to the air supply pipe section 6. The hot air is discharged from the bathroom through the first air supply end 601 and the output pipe section 13, and is discharged from the bathroom through the second air supply end 602 and the through cavity 14.

[0065] In the cooling state, the heat pump unit 9 can provide cold air to the air supply pipe section 6 , and the cold air is discharged from the bathroom through the first air supply end 601 and the output pipe section 13 without passing through the through cavity 14 .

[0066] In this embodiment, the water heater system combines the water outlet pipe section 2 and the gas supply pipe section 6, and is designed to have a common output pipe section 13, so that the overall structure of the water heater system is compact and simple. The design of the gas and water co-pipe also saves installation space accordingly, and there is no need to install an exhaust vent in the bathroom.

[0067] The water tank 1 and the heat pump unit 9 are combined in the water heater system to realize advance temperature control of the bathroom before bathing. As a result, the user can be in a more comfortable temperature range when entering the bathroom, without having to wait in the bathroom for a certain period of time before bathing, thereby improving the practicality and convenience of the water heater system.

[0068] When the user needs to schedule the temperature control of the bathroom, he can click on the "Schedule Temperature Control" mode through the wired controller or APP interface to achieve it.

[0069] The water heater system responds to the scheduled temperature control mode start instruction and enters the scheduled temperature control mode;

[0070] The temperature value in the bathroom is obtained by a temperature sensor or a temperature sensing package, and the controller 10 determines whether the temperature value is within a preset temperature value range;

[0071] If the temperature value is within the preset temperature value range, then in response to the scheduled temperature control mode end instruction, the temperature value in the bathroom is within the user's preset temperature value range, then there is no need to perform temperature control work, and the water heater system can continue to maintain the energy-saving mode;

[0072] If the temperature value is outside the preset temperature value range and the temperature value is greater than the maximum value in the preset temperature value range, it enters the cooling state; in the cooling state, the heat pump unit 9 can provide cold air for the air supply pipe section 6, and the cold air is discharged from the bathroom through the first air supply end 601 and the output pipe section 13, and does not pass through the through cavity 14. The cold air cools the bathroom and makes the bathroom reach the preset temperature range, thereby meeting the user's needs for the preset temperature and allowing the user to get a more comfortable bathing environment before bathing.

[0073] If the temperature value is outside the preset temperature range and is less than the minimum value within the preset temperature range, the system enters a heating state. In this state, the heat pump unit 9 can provide hot air to the air supply pipe section 6. The hot air is discharged from the bathroom through the first air supply end 601 and the output pipe section 13, and then discharged from the bathroom through the second air supply end 602 and the through cavity 14. In this state, the hot air heats the bathroom, bringing the bathroom temperature to within the preset temperature range, thereby meeting the user's desired preset temperature and providing the user with a more comfortable bathing environment before bathing. It is designed that part of the hot air is discharged from the bathroom through the second air supply end 602 and the cavity 14. The water tank 1 itself keeps the water inside it heated or insulated. When the hot air passes through the cavity 14, it will exchange heat with the hot water temperature of the water tank 1, and the hot air temperature will be further increased, so that the heat pump part 9 can achieve rapid heating and heating in the bathroom at a lower power. When the temperature of the water tank 1 is not high, the hot air will have an insulation effect on the water tank 1, thereby realizing the mutual transfer and mutual compensation effect between the water tank 1 and the heat pump part 9, so that the water heater system as a whole is energy-saving and has a higher heating efficiency.

[0074] This water heater system can act as a water heater as well as heating and cooling. When the scheduled temperature control function is used, the bathroom can be heated or cooled before bathing to maintain the temperature in the bathroom, ensuring that the user has a comfortable environment for bathing before bathing.

[0075] Preferably, an auxiliary heater 12 is provided on the water inlet pipe section 3 to assist the water tank 1 in quickly preheating the water flow before entering the water tank 1, thereby further improving the heating speed of the water.

[0076] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0077] The water heater system also includes:

[0078] The water return portion 11 is provided on the water outlet pipe section 2;

[0079] The water return portion 11 is designed to pump water in the water outlet pipe section 2 back into the water tank 1 .

[0080] In this embodiment, before the temperature rises, the water outlet valve 4 is controlled to open, the water inlet valve 5 is controlled to close, and the water return portion 11 is controlled to pump the water in the water outlet pipe section 2 back into the water tank 1;

[0081] The return water section 11 returns the remaining water in the outlet pipe section 2 to the water tank 1, where it is kept warm. This prevents the water remaining in each outlet pipe section 2 from being affected by the ambient temperature, which could affect the initial outlet water temperature during bathing. For example, when the ambient temperature is low, the water remaining in the outlet pipe section 2 may be affected by the ambient temperature and remain cold, resulting in a low outlet water temperature at the beginning of the bath, which could lead to a poor user experience. When pre-setting the bathroom temperature, the water in the outlet pipe section 2 can be pumped back to the water tank 1 in advance for heat preservation, thus avoiding the low outlet water temperature.

[0082] When bathing in winter, the temperature in the bathroom is relatively low. When entering the bathroom to adjust the temperature, you need to wait for a certain period of time to reach a comfortable temperature. The water heater heat exchange system can adjust the temperature in the bathroom in advance according to the settings, while keeping the water outlet pipe section 2 free of retained water to avoid the spraying of low-temperature rainwater.

[0083] Regarding the working principle of the return water part 11: the return water part 11 can adopt a reciprocating pump. The piston in the reciprocating pump reciprocates in the pump cylinder, so that the volume on one side of the piston in the pump cylinder alternately increases and decreases. When the volume increases, a water suction force is generated, and the remaining water in the water outlet pipe section 2 is first sucked into the pump cylinder through the one-way inlet valve. When the volume decreases, a pushing force is generated, and the water sucked in the pump cylinder is pushed out to the water tank 1 through the one-way discharge valve. This is repeated to pump the water in the water outlet pipe section 2 back into the water tank 1.

[0084] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0085] The first air supply end 601 is provided with a first valve 7, which is used to connect the first air supply end 601 with the output pipe section 13 and block the water outlet pipe section 2 and the output pipe section 13, or connect the water outlet pipe section 2 and the output pipe section 13 and block the first air supply end 601 and the output pipe section 13;

[0086] The second gas supply end 602 is provided with a second valve 8 , which is used to connect or block the second gas supply end 602 and the through cavity 14 .

[0087] In this embodiment, the first valve 7 is a reversing valve. In the heating state, the heat pump unit 9 can provide hot air to the air supply pipe section 6. The hot air is discharged from the bathroom through the first air supply end 601 and the output pipe section 13, and then discharged from the bathroom through the second air supply end 602 and the through cavity 14. The first valve 7 is configured to cooperate with the heat pump unit 9. In the heating state, the first valve 7 connects the first air supply end 601 and the output pipe section 13, and blocks the water outlet pipe section 2 and the output pipe section 13, so that the output pipe section 13 provides hot air to the bathroom. At the same time, the second valve 8 connects the second air supply end 602 and the through cavity 14, thereby generating heat exchange between the hot air and the hot water in the water tank 1.

[0088] Before the temperature rises, the first valve 7 connects the outlet pipe section 2 and the output pipe section 13, and blocks the first air supply end 601 from the output pipe section 13. This controls the outlet valve 4 to open, the inlet valve 5 to close, and the return water section 11 to pump the water in the outlet pipe section 2 back into the water tank 1.

[0089] In the cooling state, the first valve 7 connects the first air supply end 601 and the output pipe section 13, and blocks the water outlet pipe section 2 and the output pipe section 13, so that the output pipe section 13 provides cold air to the bathroom. The second valve 8 blocks the second air supply end 602 and the through cavity 14, so that the heat pump unit 9 can provide cold air to the air supply pipe section 6. The cold air is discharged from the bathroom through the first air supply end 601 and the output pipe section 13, and does not pass through the through cavity 14.

[0090] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0091] The water heater system further includes: a controller 10;

[0092] The water tank 1, the water outlet valve 4, the water inlet valve 5, the first valve 7, the second valve 8, the heat pump unit 9 and the water return unit 11 are all electrically connected to the controller 10;

[0093] The controller 10 is designed to:

[0094] Before the temperature rises, the water outlet valve 4 is controlled to open, the water inlet valve 5 is controlled to close, and the water return part 11 is controlled to pump the water in the water outlet pipe section 2 back into the water tank 1;

[0095] In the heating state, the heat pump unit 9 is controlled to provide hot gas to the gas supply pipe section 6, and the first valve 7 is controlled to connect the first gas supply end 601 and the output pipe section 13, and block the water outlet pipe section 2 and the output pipe section 13;

[0096] Control the second valve 8 to connect the second gas supply end 602 and the through cavity 14;

[0097] In the cooling state, the heat pump unit 9 is controlled to provide cold air to the air supply pipe section 6, and the first valve 7 is controlled to connect the first air supply end 601 and the output pipe section 13, and to block the water outlet pipe section 2 and the output pipe section 13;

[0098] The second valve 8 is controlled to block the second gas supply end 602 and the through cavity 14 .

[0099] In this embodiment, the controller 10 is configured to facilitate controlling the water heater system in different states. Before the heating state, the water outlet valve 4 is controlled to open, the water inlet valve 5 is controlled to close, and the water return unit 11 is controlled to pump the water in the water outlet pipe section 2 back into the water tank 1. This prevents the water remaining in each water outlet pipe section 2 from being affected by the external ambient temperature and affecting the initial water outlet temperature during bathing.

[0100] In the heating state, the heat pump unit 9 is controlled to provide hot gas to the gas supply pipe section 6, and the first valve 7 is controlled to connect the first gas supply end 601 and the output pipe section 13, and block the water outlet pipe section 2 and the output pipe section 13;

[0101] The second valve 8 is controlled to connect the second air supply port 602 and the through cavity 14. In the heating state, the hot air heats the bathroom, bringing it to a preset temperature range, thereby satisfying the user's desired preset temperature and providing a more comfortable bathing environment before bathing. A portion of the hot air is designed to be discharged from the bathroom via the second air supply port 602 and the through cavity 14. The water tank 1 itself heats or insulates the water within it. When the hot air passes through the through cavity 14, it exchanges heat with the hot water in the water tank 1, further raising the hot air temperature. This allows the heat pump unit 9 to quickly heat the bathroom at a lower power. When the water tank 1 is not at a high temperature, the hot air passing through it will insulate the water tank 1, thereby achieving a mutual heat transfer and complementary effect between the water tank 1 and the heat pump unit 9, making the water heater system energy-efficient and achieving higher heating efficiency.

[0102] In the cooling state, the heat pump unit 9 is controlled to provide cold air to the air supply pipe section 6, and the first valve 7 is controlled to connect the first air supply end 601 and the output pipe section 13, and to block the water outlet pipe section 2 and the output pipe section 13;

[0103] The second valve 8 is controlled to block the second air supply end 602 and the through cavity 14; the cold air cools the bathroom so that the bathroom reaches a preset temperature range, thereby meeting the user's need for the preset temperature and allowing the user to get a more comfortable bathing environment before bathing.

[0104] After the temperature control is completed, by controlling the water outlet valve 4 and the water inlet valve 5 to be opened, the first valve 7 connects the water outlet pipe section 2 and the output pipe section 13, and the water is controlled to enter the water tank 1 through the water inlet pipe section 3 and output from the water tank 1 through the water outlet pipe section 2, so that bathing can be carried out.

[0105] Example 2

[0106] like Figure 2 As shown, a water heater control method is provided for controlling the above water heater system, and the water heater control method includes:

[0107] In the preset temperature control mode, obtain the temperature value in the bathroom and determine whether the temperature value is within the preset temperature range;

[0108] If the temperature value is within the preset temperature range, the scheduled temperature control mode ends;

[0109] If the temperature value is outside the preset temperature range and the temperature value is greater than the maximum value in the preset temperature range, the system enters the cooling state;

[0110] If the temperature value is outside the preset temperature range and is less than the minimum value in the preset temperature range, the temperature rise state is entered.

[0111] In this embodiment, when the user needs to schedule the temperature control of the bathroom, he can click on the "schedule temperature control" mode through the wired controller or APP interface to achieve it.

[0112] The water heater system responds to the scheduled temperature control mode start instruction and enters the scheduled temperature control mode;

[0113] The temperature value in the bathroom is obtained by a temperature sensor or a temperature sensing package, and the controller 10 determines whether the temperature value is within a preset temperature value range;

[0114] If the temperature value is within the preset temperature value range, then in response to the scheduled temperature control mode end instruction, the temperature value in the bathroom is within the user's preset temperature value range, then there is no need to perform temperature control work, and the water heater system can continue to maintain the energy-saving mode;

[0115] If the temperature value is outside the preset temperature value range and the temperature value is greater than the maximum value in the preset temperature value range, it enters the cooling state; in the cooling state, the heat pump unit 9 can provide cold air for the air supply pipe section 6, and the cold air is discharged from the bathroom through the first air supply end 601 and the output pipe section 13, and does not pass through the through cavity 14. The cold air cools the bathroom and makes the bathroom reach the preset temperature range, thereby meeting the user's needs for the preset temperature and allowing the user to get a more comfortable bathing environment before bathing.

[0116] If the temperature value is outside the preset temperature range and is less than the minimum value within the preset temperature range, the system enters a heating state. In this state, the heat pump unit 9 can provide hot air to the air supply pipe section 6. The hot air is discharged from the bathroom through the first air supply end 601 and the output pipe section 13, and then discharged from the bathroom through the second air supply end 602 and the through cavity 14. In this state, the hot air heats the bathroom, bringing the bathroom temperature to within the preset temperature range, thereby meeting the user's desired preset temperature and providing the user with a more comfortable bathing environment before bathing. It is designed that part of the hot air is discharged from the bathroom through the second air supply end 602 and the cavity 14. The water tank 1 itself keeps the water inside it heated or insulated. When the hot air passes through the cavity 14, it will exchange heat with the hot water temperature of the water tank 1, and the hot air temperature will be further increased, so that the heat pump part 9 can achieve rapid heating and heating in the bathroom at a lower power. When the temperature of the water tank 1 is not high, the hot air will have an insulation effect on the water tank 1, thereby realizing the mutual transfer and mutual compensation effect between the water tank 1 and the heat pump part 9, so that the water heater system as a whole is energy-saving and has a higher heating efficiency.

[0117] This water heater system can act as a water heater as well as heating and cooling. When the scheduled temperature control function is used, the bathroom can be heated or cooled before bathing to maintain the temperature in the bathroom, ensuring that the user has a comfortable environment for bathing before bathing.

[0118] Example 3

[0119] like Figure 3 As shown, the difference from the second embodiment is that the water heater control method provided in the third embodiment enters the return water state and then the heating state if the temperature value is outside the preset temperature value range and the temperature value is less than the minimum value in the preset temperature value range;

[0120] The water return state includes: controlling the water outlet valve 4 to open, controlling the water inlet valve 5 to close, and controlling the water return part 11 to pump the water in the water outlet pipe section 2 back into the water tank 1 .

[0121] In this embodiment, before the temperature rises, the water outlet valve 4 is controlled to open, the water inlet valve 5 is controlled to close, and the water return portion 11 is controlled to pump the water in the water outlet pipe section 2 back into the water tank 1; the water return portion 11 returns the remaining water in the water outlet pipe section 2 to the water tank 1 to enter the heat preservation state, thereby preventing the water remaining in each water outlet pipe section 2 from being affected by the external ambient temperature and affecting the initial water outlet temperature during bathing.

[0122] Furthermore, in the process of controlling the return water part 11 to pump the water in the outlet pipe section 2 back into the water tank 1, the water flow in the outlet pipe section 2 is obtained. When the water flow is equal to zero, the return water part 11 is controlled to stop working and the outlet valve 4 is controlled to be closed.

[0123] By obtaining the water flow in the outlet pipe section 2, if the water flow is equal to zero, it indicates that there is no residual water in the current outlet pipe section 2, then the return water unit 11 is controlled to stop working and the outlet valve 4 is controlled to close. The return water unit 11 is designed to continuously pump back the water flow in each pipe section when the water flow in the outlet pipe section 2 is not zero, so as to minimize the residual water in each pipe section and prevent the water remaining in each pipe section from being affected by the external ambient temperature and affecting the initial water temperature during bathing.

[0124] Optionally, in one implementation of this embodiment,

[0125] The preset temperature value range includes a first preset temperature value range, a second preset temperature value range and a third preset temperature value range;

[0126] The first preset temperature range is 16°C to 24°C, the second preset temperature range is 25°C to 26°C, and the third preset temperature range is 27°C to 29°C.

[0127] In this embodiment, the first preset temperature value range is 16℃~24℃, corresponding to cold comfort, the second preset temperature value range is 25℃~26℃, corresponding to warm comfort, and the third preset temperature value range is 27℃~29℃, corresponding to hot comfort. The three preset temperature value ranges can meet the user's diverse needs for bathroom temperature.

[0128] Optionally, in one implementation of this embodiment,

[0129] In the scheduled temperature control mode, after the heating state or the cooling state, if the temperature value is within the preset temperature value range, the remaining time before bathing is obtained. When the remaining time is equal to the preset time, the heating state or the cooling state is ended, and the water outlet valve 4 and the water inlet valve 5 are controlled to be open.

[0130] In this embodiment, preferably, the preset time can be 1 minute. At this time, the remaining time before bathing is short, and the bathroom has achieved a comfortable temperature environment, achieving the temperature control purpose. The water outlet valve 4 and the water inlet valve 5 are adjusted to open, waiting for the user to enter the bathroom for bathing, and the water heater system can discharge water smoothly.

[0131] Example 4

[0132] This embodiment provides an electronic device, including:

[0133] a memory for storing one or more computer-executable instructions;

[0134] The processor is used to call and execute computer executable instructions in the processor, thereby implementing the control method in the second or third embodiment.

[0135] In this embodiment, before the temperature rises, the water outlet valve 4 is controlled to open, the water inlet valve 5 is controlled to close, and the water return portion 11 is controlled to pump the water in the water outlet pipe section 2 back into the water tank 1. This can prevent the water remaining in each water outlet pipe section 2 from being affected by the external ambient temperature and affecting the initial water outlet temperature during bathing.

[0136] In the heating state, the heat pump unit 9 is controlled to provide hot gas to the gas supply pipe section 6, and the first valve 7 is controlled to connect the first gas supply end 601 and the output pipe section 13, and block the water outlet pipe section 2 and the output pipe section 13;

[0137] The second valve 8 is controlled to connect the second air supply port 602 and the through cavity 14. In the heating state, the hot air heats the bathroom, bringing it to a preset temperature range, thereby satisfying the user's desired preset temperature and providing a more comfortable bathing environment before bathing. A portion of the hot air is designed to be discharged from the bathroom via the second air supply port 602 and the through cavity 14. The water tank 1 itself heats or insulates the water within it. When the hot air passes through the through cavity 14, it exchanges heat with the hot water in the water tank 1, further raising the hot air temperature. This allows the heat pump unit 9 to quickly heat the bathroom at a lower power. When the water tank 1 is not at a high temperature, the hot air passing through it will insulate the water tank 1, thereby achieving a mutual heat transfer and complementary effect between the water tank 1 and the heat pump unit 9, making the water heater system energy-efficient and achieving higher heating efficiency.

[0138] In the cooling state, the heat pump unit 9 is controlled to provide cold air to the air supply pipe section 6, and the first valve 7 is controlled to connect the first air supply end 601 and the output pipe section 13, and to block the water outlet pipe section 2 and the output pipe section 13;

[0139] The second valve 8 is controlled to block the second air supply end 602 and the through cavity 14; the cold air cools the bathroom so that the bathroom reaches a preset temperature range, thereby meeting the user's need for the preset temperature and allowing the user to get a more comfortable bathing environment before bathing.

[0140] After the temperature control is completed, by controlling the water outlet valve 4 and the water inlet valve 5 to be opened, the first valve 7 connects the water outlet pipe section 2 and the output pipe section 13, and the water is controlled to enter the water tank 1 through the water inlet pipe section 3 and output from the water tank 1 through the water outlet pipe section 2, so that bathing can be carried out.

[0141] The water heater control method can heat or cool the bathroom before bathing to maintain the temperature in the bathroom, ensuring that the user has a comfortable environment for bathing before bathing.

[0142] Especially when bathing in winter, the temperature in the bathroom is relatively low. When entering the bathroom to adjust the temperature, you need to wait for a certain period of time before reaching a comfortable temperature. This control method can adjust the temperature in the bathroom in advance according to the settings, while keeping each pipe section free of residue and insulated to avoid the spraying of low-temperature rainwater.

[0143] In summary, the ingenious design of the water heater system lies in:

[0144] First, the water heater system integrates the water outlet and gas supply pipes into a common output section, making the overall structure compact and simple. The shared gas and water piping also saves installation space, eliminating the need for a separate exhaust vent in the bathroom. Furthermore, the integrated water tank and heat pump design within the water heater system allows for pre-conditioning of the bathroom temperature before showering. This ensures users are within a comfortable temperature range upon entering the shower room, eliminating the need to wait in the bathroom for an extended period before showering, enhancing the system's practicality and ease of use. It is designed that part of the hot air is discharged from the bathroom through the second air supply end and the cavity. The water tank itself keeps the water inside it heated or insulated. When the hot air passes through the cavity, it will exchange heat with the hot water temperature in the water tank, and the hot air temperature will be further increased, so that the heat pump unit can achieve rapid heating and heating in the bathroom at a lower power. When the temperature of the water tank is not high, the hot air will have an insulation effect on the water tank, thereby realizing the mutual transfer and compensation effect between the water tank and the heat pump unit, making the water heater system energy-saving as a whole and having higher heating efficiency.

[0145] Second, before the temperature rises, the water outlet valve is controlled to open, the water inlet valve is controlled to close, and the return water part is controlled to pump the water in the outlet pipe section back into the water tank; the return water part returns the remaining water in the outlet pipe section to the water tank and enters the heat preservation state, thereby preventing the water retained in each outlet pipe section from being affected by the external ambient temperature and affecting the initial water outlet temperature during bathing.
