For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] When bathing in a low temperature environment or a high temperature environment, the temperature in the bathroom will be relatively high or relatively low, and the comfort level is 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 they can bathe, which is inconvenient.

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

[0056] Embodiment 1:

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

[0058] A water tank 1, wherein the water tank 1 is provided with a through cavity 13 communicating with the bathroom;

[0059] A water outlet pipe section 2 and a water inlet pipe section 3, the water outlet pipe section 2 is connected to the water tank 1, and a water outlet valve 4 is provided on the water outlet pipe section 2, and the water inlet pipe section 3 is connected to the water tank 1, and a water inlet valve 5 is provided on the water inlet pipe section 3;

[0060] An output pipe section 13, 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, 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 13;

[0062] A heat pump unit 9, the heat pump unit 9 is used to provide hot air or cold air to the air 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, and 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 13;

[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 and does not pass through the through cavity 13 .

[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 with 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-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 achieve 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 enters the scheduled temperature control mode in response to the scheduled temperature control mode start instruction;

[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 13. 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 in the preset temperature range, the temperature rise state is entered. In the temperature rise state, the heat pump unit 9 can provide hot air to the air supply pipe section 6, and 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 13. In the temperature rise state, the hot air heats the bathroom to a preset temperature range, thereby satisfying the user's need for the preset temperature, so that the user can get a more comfortable bathing environment before bathing. It is designed that part of the hot air is discharged from the bathroom via the second air supply end 602 and the cavity 13. The water tank 1 itself keeps the water inside it heated or insulated. When the hot air passes through the cavity 13, heat exchange occurs with the hot water temperature of the water tank 1. The hot air temperature is further increased, so that the heat pump unit 9 can achieve rapid heating and heating in the bathroom at a relatively low power. When the temperature of the water tank 1 is not high, the hot air passing through will have an insulation effect on the water tank 1, thereby achieving the mutual transfer and mutual compensation effect between the water tank 1 and the heat pump unit 9, so that the water heater system is energy-saving as a whole 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 arranged on the water outlet pipe section 2;

[0079] The water return portion 11 is designed to pump the 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 be opened, the water inlet valve 5 is controlled to be closed, 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;

[0081] The water return section 11 returns the remaining water in the water outlet pipe section 2 to the water tank 1 to keep warm, thereby preventing the water in each water outlet pipe section 2 from being affected by the external ambient temperature and affecting the initial water outlet temperature during bathing. For example, when the external ambient temperature is low, the water in the water outlet pipe section 2 is affected by the external ambient temperature and is in a cold state, resulting in a low water outlet temperature at the beginning of bathing and a poor user experience. When the bathroom temperature is scheduled for temperature control, the water in the water outlet pipe section 2 can be pumped back to the water tank 1 in advance for heat preservation, thereby avoiding the situation where the water outlet temperature is low.

[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 get 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 rain water.

[0083] Regarding the working principle of the water return part 11: the water return 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 increases and decreases alternately. 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 push 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 achieve the goal of pumping 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 gas supply end 601 is provided with a first valve 7, and the first valve 7 is used to connect the first gas 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 gas supply end 601 and the output pipe section 13;

[0086] The second gas supply end 602 is provided with a second valve 8 , and the second valve 8 is used for connecting or blocking the second gas supply end 602 and the through cavity 13 .

[0087] In this embodiment, the first valve 7 is a reversing valve; in the temperature rising state, the heat pump unit 9 can provide hot air for the air supply pipe section 6, and 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 13; the setting of the first valve 7 can cooperate with the heat pump unit 9 to work. In the temperature rising 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 for the bathroom, and at the same time, the second valve 8 connects the second air supply end 602 and the through cavity 13, so that heat exchange occurs 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 and the output pipe section 13, cooperates to control the outlet valve 4 to open, controls the inlet valve 5 to close, and controls the return water part 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 for the bathroom. The second valve 8 blocks the second air supply end 602 and the through cavity 13, so that the heat pump unit 9 can provide cold air for the air supply pipe section 6. The cold air is discharged from the bathroom via the first air supply end 601 and the output pipe section 13, and does not pass through the through cavity 13.

[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 be opened, the water inlet valve 5 is controlled to be closed, 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 temperature rising state, the heat pump unit 9 is controlled to provide hot 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;

[0096] Control the second valve 8 to connect the second gas supply end 602 and the through cavity 13;

[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 13 .

[0099] In this embodiment, the controller 10 is arranged to facilitate controlling the water heater system in different states. 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, thereby preventing the water remaining in each water outlet pipe section 2 from being affected by the external environment temperature and affecting the initial water outlet temperature during bathing;

[0100] In the temperature rising state, the heat pump unit 9 is controlled to provide hot 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;

[0101] The second valve 8 is controlled to conduct the second air supply end 602 and the through cavity 13; in the heating state, the hot air heats up the bathroom, so that the bathroom reaches a preset temperature range, thereby satisfying the user's need for the preset temperature, so that the user can get a more comfortable bathing environment before bathing. And part of the hot air is designed to be discharged from the bathroom through the second air supply end 602 and the through cavity 13, and the water tank 1 itself keeps the water inside it heated or insulated. When the hot air passes through the through cavity 13, 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 unit 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 of heat between the water tank 1 and the heat pump unit 9, and the effect of mutual compensation, so that the water heater system is energy-saving as a whole and has a 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 13; 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, the water outlet valve 4 and the water inlet valve 5 are both 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 from 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] Embodiment 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 value range;

[0108] If the temperature value is within the preset temperature value 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 cooling state is entered;

[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 wire controller or APP interface to achieve it.

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

[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 13. 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 in the preset temperature range, the temperature rise state is entered. In the temperature rise state, the heat pump unit 9 can provide hot air to the air supply pipe section 6, and 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 13. In the temperature rise state, the hot air heats the bathroom to a preset temperature range, thereby satisfying the user's need for the preset temperature, so that the user can get a more comfortable bathing environment before bathing. It is designed that part of the hot air is discharged from the bathroom via the second air supply end 602 and the cavity 13. The water tank 1 itself keeps the water inside it heated or insulated. When the hot air passes through the cavity 13, heat exchange occurs with the hot water temperature of the water tank 1. The hot air temperature is further increased, so that the heat pump unit 9 can achieve rapid heating and heating in the bathroom at a relatively low power. When the temperature of the water tank 1 is not high, the hot air passing through will have an insulation effect on the water tank 1, thereby achieving the mutual transfer and mutual compensation effect between the water tank 1 and the heat pump unit 9, so that the water heater system is energy-saving as a whole 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] Embodiment 3

[0119] like Figure 3 As shown, the difference from the second embodiment is that, in the water heater control method provided in the third embodiment, 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, the water return state is entered, and then the temperature rise state is entered;

[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 be opened, the water inlet valve 5 is controlled to be closed, 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 retained 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 water return part 11 to pump the water in the water outlet pipe section 2 back into the water tank 1, the water flow in the water outlet pipe section 2 is obtained. When the water flow is equal to zero, the water return part 11 is controlled to stop working and the water outlet valve 4 is controlled to be closed.

[0123] By obtaining the water flow in the outlet pipe section 2, when 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 retained in each pipe section from being affected by the external ambient temperature and affecting the initial outlet water temperature during bathing.

[0124] Optionally, in an 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 value range is 16°C to 24°C, the second preset temperature value range is 25°C to 26°C, and the third preset temperature value 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 an 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 to achieve the temperature control purpose. The water outlet valve 4 and the water inlet valve 5 are adjusted to open to wait for the user to enter the bathroom for bathing, and the water heater system can discharge water smoothly.

[0131] Embodiment 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, so as to implement 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 be opened, the water inlet valve 5 is controlled to be closed, 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, thereby preventing the water remaining in each water outlet pipe section 2 from being affected by the external environment temperature and affecting the initial water outlet temperature during bathing;

[0136] In the temperature rising state, the heat pump unit 9 is controlled to provide hot 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;

[0137] The second valve 8 is controlled to conduct the second air supply end 602 and the through cavity 13; in the heating state, the hot air heats up the bathroom, so that the bathroom reaches a preset temperature range, thereby satisfying the user's need for the preset temperature, so that the user can get a more comfortable bathing environment before bathing. And part of the hot air is designed to be discharged from the bathroom through the second air supply end 602 and the through cavity 13, and the water tank 1 itself keeps the water inside it heated or insulated. When the hot air passes through the through cavity 13, 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 unit 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 of heat between the water tank 1 and the heat pump unit 9, and the effect of mutual compensation, so that the water heater system is energy-saving as a whole and has a 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 13; 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, the water outlet valve 4 and the water inlet valve 5 are both 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 from 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 to get 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 rain water.

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

[0144] First, the water heater system combines the water outlet pipe section and the gas supply pipe section, and is designed with a common output pipe section, making the overall structure of the water heater system 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. In addition, the water tank and the heat pump are combined in the water heater system to achieve advance temperature control of the bathroom before bathing. As a result, when the user enters the bathing room, he or she can be in a more comfortable temperature range, and there is no need to wait in the bathroom for a certain period of time before bathing, which improves the practicality and convenience of the water heater system. It is designed that part of the hot air is discharged from the bathroom through the second air supply end and the through cavity. The water tank itself keeps the water inside it heated or insulated. When the hot air passes through the through cavity, it will exchange heat with the hot water temperature in the water tank. The hot air temperature is 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 achieving the effect of mutual transfer and mutual compensation between the water tank and the heat pump unit, making the water heater system energy-saving as a whole and having a 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 water return part is controlled to pump the water in the water outlet pipe section back into the water tank; the water return part returns the remaining water in the water outlet pipe section to the water tank and enters the heat preservation state, thereby preventing the water retained in each water outlet pipe section from being affected by the external ambient temperature and affecting the initial water outlet temperature during bathing.

[0146] It is further understood that in the present disclosure, "plurality" refers to two or more than two, and other quantifiers are similar thereto. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. The singular forms "a", "the" and "the" are also intended to include plural forms, unless the context clearly indicates other meanings.
