The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0028] In the following description, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0030] The embodiment of the present application provides a control method for a water heater, referring to Figure 1 As shown, the method comprises the following steps:

[0031] Step 101: Obtain first reference information.

[0032] In the embodiment of the present application, the first reference information includes but is not limited to at least one of the following reference information: the working state of the heat exchange device, reference information of the environment in which the water heater is located, input instructions, and time reference information.

[0033] The heat exchange device includes but is not limited to a heat pump. When a heat pump is selected as the heat exchange device, an air source heat pump may be further selected to realize heat exchange.

[0034] The time reference information includes but is not limited to the current time at the heat exchange device. The reference information of the environment in which the water heater is located includes but is not limited to the temperature of the environment in which the water heater is located and / or the humidity of the environment in which the water heater is located. The working state of the heat exchange device includes but is not limited to the hot water making state and the non-hot water making state. Here, the non-hot water making state includes a working state different from the hot water making state, such as a heat preservation state.

[0035] In a first achievable scenario (the first scenario uses the first mode of the water heater), the first reference information includes but is not limited to the input command, the working state of the heat exchange device, and the first temperature of the environment in which the water heater is located; at this time, the first reference information is used to determine the target air inlet and target air outlet of the heat exchange device of the water heater in the first scenario. In practical applications, the first scenario can be regarded as the first fresh air scenario, in which the water heater can realize the functions corresponding to the indoor circulation purification mode and the outdoor fresh air introduction mode.

[0036] In a realizable second scenario (the second scenario uses the second mode of the water heater), the first reference information includes but is not limited to the first preset time period, the current time, and the second temperature of the environment in which the water heater is located; at this time, the second reference information is used to determine the target air inlet and target air outlet of the heat exchange device of the water heater in the second scenario. In practical applications, the second scenario can be regarded as the second fresh air scenario, in which the water heater can not only realize the functions corresponding to the indoor circulation purification mode and the outdoor fresh air introduction mode, but also can pre-start the fresh air and hot water at a specific time, thereby pre-providing a suitable environment. The second fresh air scenario is also called the holiday fresh air scenario.

[0037] The execution subject of this embodiment may be a water heater, which has functions such as data processing, data communication, and program operation. Generally, the operation of each component in the water heater can be driven by a core controller / processor, so the execution subject of this embodiment may also be the controller / processor in the water heater.

[0038] Step 102: Determine a target air inlet and a target air outlet of a heat exchange device of the water heater according to the first reference information.

[0039] In an embodiment of the present application, when the first reference information is obtained, the target air inlet and target air outlet corresponding to the first reference information can be flexibly determined, that is, the air can be introduced from the outdoor air inlet of the heat exchange device and discharged from the indoor air outlet of the heat exchange device or the outdoor air outlet of the heat exchange device; or the air can be introduced from the indoor air inlet of the heat exchange device and discharged from the indoor air outlet of the heat exchange device.

[0040] Step 103: Control air to be introduced from the target air inlet and discharged from the target air outlet.

[0041] The target air inlet includes an outdoor air inlet of the heat exchange device or an indoor air inlet of the heat exchange device, and the target air outlet includes an outdoor air outlet of the heat exchange device or an indoor air outlet of the heat exchange device.

[0042] In the embodiment of the present application, the air is controlled to be introduced from the outdoor air inlet of the heat exchange device and discharged from the indoor air outlet of the heat exchange device or discharged from the outdoor air outlet of the heat exchange device, so as to realize the function of introducing fresh air and improve the indoor air quality; wherein, the air is introduced from the outdoor air inlet of the heat exchange device and discharged from the indoor air outlet of the heat exchange device, and the cold air can be recovered while the fresh air is introduced, so as to improve the indoor air quality and reduce the indoor temperature. The air is controlled to be introduced from the indoor air inlet of the heat exchange device and discharged from the indoor air outlet of the heat exchange device, so as to realize the function of internal circulation purification and improve the indoor air quality.

[0043] That is to say, the water heater of the present application has two air inlets and two air outlets, and the selection of the air inlets and the air outlets can be determined according to the first reference information, or can be considered to be determined according to the mode corresponding to the first reference information.

[0044] The control method of the water heater provided in the embodiment of the present application obtains first reference information; according to the first reference information, flexibly selects the target air inlet of the heat exchange device of the water heater and the target air outlet of the heat exchange device; thereby controlling the air to be introduced from the target air inlet and discharged from the target air outlet, so as to meet the demand for fresh air introduction in different scenarios, and realize intelligent ventilation control with the help of the water heater; wherein, the target air inlet includes one of the outdoor air inlet of the heat exchange device and the indoor air inlet of the heat exchange device, and the target air outlet includes one of the outdoor air outlet of the heat exchange device and the indoor air outlet of the heat exchange device.

[0045] In some embodiments of the present application, the first reference information includes an input instruction and / or a working state of the heat exchange device. Step 102 determines the target air inlet and the target air outlet of the heat exchange device of the water heater according to the first reference information, which can be achieved by the following steps:

[0046] If the input command is the first command and / or the working state is a non-heating water state, the target air inlet of the heat exchange device of the water heater is determined to be the outdoor air inlet, and the target air outlet of the heat exchange device is determined to be the indoor air outlet.

[0047] The first instruction is used to start the outdoor fresh air introduction mode. Here, when the water heater determines that the input instruction is the first instruction and / or the working state is not the hot water production state, it further determines to introduce outdoor air from the outdoor air inlet and exhaust it from the indoor air outlet to improve the indoor air quality.

[0048] In some embodiments of the present application, the first reference information includes an input instruction, and step 102 determines the target air inlet and the target air outlet of the heat exchange device of the water heater according to the first reference information, which can be achieved by the following steps:

[0049] If the input instruction is the second instruction, the target air inlet of the heat exchange device of the water heater is determined to be the indoor air inlet, and the target air outlet of the heat exchange device is determined to be the indoor air outlet.

[0050] The second instruction is used to start the indoor circulation purification mode. Here, when the water heater determines that the input instruction is the second instruction, it further determines to introduce outdoor air from the indoor air inlet and discharge it from the indoor air outlet to achieve indoor circulation and improve indoor air quality.

[0051] In some embodiments of the present application, the first reference information includes an input instruction and / or a working state of the heat exchange device. Step 102 determines the target air inlet and the target air outlet of the heat exchange device of the water heater according to the first reference information, which can be achieved by the following steps:

[0052] If the input command is the first command and the working state is the hot water making state, obtaining the first temperature of the environment where the water heater is located and / or the input command;

[0053] According to the first temperature and / or the input instruction, a target air inlet and a target air outlet are determined.

[0054] In the embodiment of the present application, when the outdoor fresh air introduction mode is started and the working state is the hot water making state, further, the air inlet and outlet can be selected more accurately in combination with the first temperature of the environment in which the water heater is located and / or the input instruction to achieve precise ventilation control.

[0055] Furthermore, the above-mentioned determination of the target air inlet and the target air outlet according to the first temperature and / or the input instruction can be implemented by the following steps:

[0056] If the first temperature satisfies the cold recovery condition and / or the input instruction indicates cold recovery, the target air inlet of the heat exchange device of the water heater is determined to be the outdoor air inlet, and the target air outlet of the heat exchange device is determined to be the indoor air outlet.

[0057] Here, the first temperature satisfies the cold recovery condition, including: the first temperature is less than or equal to a temperature threshold, or the first temperature is within a preset temperature range.

[0058] In the state of making hot water, the first temperature satisfies the cold recovery condition, for example, the first temperature is greater than the temperature threshold, and the hot water machine can automatically select cold air recycling. Alternatively, in the state of making hot water, the first temperature satisfies the cold recovery condition, and further, cold air recycling is selected when the input instruction indicates cold recovery, so that cold air can be introduced into the room according to the actual cold air recycling demand to achieve the purpose of cooling.

[0059] It can be seen that the present application adds a judgment condition for cold recovery in the first mode, which can not only produce hot water during the high temperature in summer, but also reduce the indoor temperature to a certain extent, improve the comfort of the indoor environment, and achieve the effect of energy saving and cooling.

[0060] In some embodiments of the present application, the above-mentioned determination of the target air inlet and the target air outlet according to the first temperature and / or the input instruction can be achieved by the following steps:

[0061] If the first temperature does not satisfy the cold recovery condition and / or the input instruction indicates not to perform cold recovery, the target air inlet of the heat exchange device of the water heater is determined to be the outdoor air inlet, and the target air outlet of the heat exchange device is determined to be the outdoor air outlet.

[0062] The first temperature does not meet the cold recovery condition, including: the first temperature is less than the temperature threshold, or the first temperature is not within a preset temperature range.

[0063] In the hot water making state, the first temperature does not meet the cold recovery condition, for example, the first temperature is less than the temperature threshold, or the input instruction indicates not to perform cold recovery, that is, not to select cold air reuse, then the cold air generated by the water heater in the hot water making state will be discharged first.

[0064] Further, after controlling the air to be introduced from the outdoor air inlet and discharged from the outdoor air outlet, the method further includes:

[0065] If the working state of the heat exchange device is switched from the hot water making state to the non-hot water making state, the air is controlled to be introduced from the outdoor air inlet and discharged from the indoor air outlet.

[0066] Here, if the working state of the heat exchange device switches from the hot water making state to the non-hot water making state, indicating that the water heater exits the hot water making state, at this time, fresh air can be introduced. This reasonable way of introducing fresh air can not only improve the indoor air quality, but also can introduce fresh air according to actual needs.

[0067] In some embodiments of the present application, the first reference information further includes a first preset time period, a current time, and a second temperature of the environment in which the water heater is located. Step 102 determines the target air inlet and the target air outlet of the heat exchange device of the water heater according to the first reference information, which can be achieved by the following steps:

[0068] If a first relationship is satisfied between the current time and the first preset time period, and the second temperature does not satisfy the cold recovery condition, the target air inlet is determined to be an outdoor air inlet, and the target air outlet is determined to be an outdoor air outlet.

[0069] Here, if the current time satisfies the first relationship with the first preset time period, and the second temperature does not satisfy the cold recovery condition, for example, during a non-summer high temperature holiday, the fan assembly can be started to perform ventilation for a certain period of time.

[0070] The first preset time period may be a pre-set time period, including the current time advancing with time, and determining the time advancement progress of the current time in the first preset time period based on the first preset time period.

[0071] The first relationship may be that the time progress in the first preset period at the current time reaches 80% of the first preset period. The first preset period may also be that the current time is a specific day in the first preset period.

[0072] Here, the first relationship between the current time and the first preset period includes: the current time is a certain time within the first preset period and / or the current time progress reaches the preset progress of the first preset period. The preset progress can be set according to actual needs, for example, 80%.

[0073] That is to say, the present application adds a fresh air introduction function in the second mode, that is, the holiday fresh air scene, to prepare a better air quality environment for users and provide comfortable and healthy hot water.

[0074] In some embodiments of the present application, if a first relationship is satisfied between the current time and the first preset time period, and the second temperature does not satisfy the cold recovery condition, the heating module corresponding to the indoor air outlet is controlled to be turned on, and the target air inlet is determined to be the outdoor air inlet, and the target air outlet is determined to be the indoor air outlet.

[0075] Here, if the current time satisfies the first relationship with the first preset time period, and the second temperature does not meet the cold recovery condition, for example, during non-summer high temperature holidays, when the indoor valve is selected to open, the air introduced into the room can be heated, thereby achieving the adjustment of the indoor temperature.

[0076] In some embodiments of the present application, if the current time satisfies the first relationship with the first preset time period, and the second temperature satisfies the cold recovery condition, the target air inlet is determined to be the outdoor air inlet, and the target air outlet is determined to be the indoor air outlet. In this way, cold air can be reused to achieve the purpose of lowering the indoor temperature.

[0077] Further, controlling the air to be introduced from the target air inlet and discharged from the target air outlet includes: controlling the water heater to enter the sterilization mode, and during the sterilization process, controlling the fan assembly of the water heater to turn on, introducing air from the outdoor air inlet, and discharging it from the indoor air outlet. It can be seen that when the application discharges the air to the indoor air outlet, the air can be sterilized and the air quality can be improved.

[0078] It can be seen that the present application can not only utilize the cold air generated by hot water to cool the room during the high temperature in summer, but also improve the comfort of the environment by setting a holiday mode with a cold recovery function when the user goes out on vacation in summer.

[0079] From the above content, it can be seen that this application adds ventilation function and cold recovery judgment in the holiday mode, so that users can have not only healthy hot water but also better air quality when they return home after the holiday. At the same time, during the high temperatures in summer, the cold recovery function can help users have a better physical experience when entering the house.

[0080] In some embodiments of the present application, if the target air outlet is an indoor air outlet, step 103 controls the air to be introduced from the target air inlet and discharged from the target air outlet, which can be achieved by the following steps: control the sterilization module corresponding to the indoor air outlet to open, and control the air to be introduced from the target air inlet and discharged from the indoor air outlet.

[0081] Among them, the sterilization module can be an ultraviolet lamp (UV), a negative ion module, etc.

[0082] From the above content, it can be seen that the present application adds a fresh air function to the water heater, which can make full use of the components of the water heater and meet the user's fresh air needs without adding equipment; at the same time, the fresh air function can not only introduce fresh air from the outside, but also perform internal circulation sterilization and purification of indoor air.

[0083] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

When the second control valve 320 is located at the B1 position, the indoor air outlet 3024 is opened, and the air outlet of the water heater is discharged into the room through the indoor air outlet 3024 of the heat exchange device; when the second control valve 320 is located at the B2 position, the outdoor air outlet 3023 is opened, and the air outlet of the water heater is discharged to the outside through the outdoor air outlet 3023 of the heat exchange device;

[0116] The heat exchange device 302 is used to heat the water in the water tank of the water heater;

[0117] Memory 303, used to store executable instructions;

[0118] The processor 304 is used to execute the executable instructions stored in the memory to implement the aforementioned water heater control method.

[0119] Below, taking the control method of the water heater provided by the present application in the first scenario as an example, the control method of the water heater with fresh air function provided by the present application is described:

[0120] See also Figure 5 As shown, when the user turns on the fresh air mode, the user can choose between the indoor circulation purification mode and the indoor fresh air introduction mode.

[0121] Combination Figure 4 and Figure 5When the user turns on the fresh air mode, the indoor circulation purification mode and the indoor fresh air introduction mode can be selected. When the indoor circulation purification mode is selected, the first control valve 310 at the air inlet of the heat pump is set to the A1 position, that is, the wind at the air inlet of the heat pump comes from the room; when the outdoor fresh air introduction mode is selected, the first control valve 310 at the air inlet of the heat pump is set to the A2 position, that is, the wind at the air inlet of the heat pump comes from the outside. Then, it is judged whether the heat pump is in the working state of making hot water. When it is not in the working state of making hot water, the second control valve 320 at the indoor air outlet is set to the B1 position. At the same time, the indoor air outlet sterilization module 3025 at the indoor air outlet is turned on, and the heat pump fan is turned on to introduce fresh air into the user's room.

[0122] When the heat pump is in the hot water production state, it is necessary to determine whether it is the high temperature stage in summer. When it is in the high temperature stage in summer, it is up to the user to decide whether to reuse the heat pump cold air. When the heat pump cold air is reused, the second control valve 320 at the indoor air outlet is set to the B1 position, and at the same time, the indoor air outlet sterilization module 3025 at the indoor air outlet is turned on, and the heat pump fan is turned on to introduce fresh air into the user's room; when it is not in the high temperature stage in summer, or the user does not choose to reuse the heat pump cold air, the second control valve 320 at the indoor air outlet is set to the B2 position, and after the heat pump hot water production work is completed, the fresh air is introduced, that is, the second control valve 320 at the indoor air outlet is opened again and set to the B1 position, and at the same time, the indoor air outlet sterilization module 3025 at the indoor air outlet is turned on, and the heat pump fan is turned on to introduce fresh air into the user's room.

[0123] Below, taking the control method of the water heater provided by the present application in the second scenario as an example, the control method of the water heater with fresh air function provided by the present application is described:

[0124] See also Figure 6As shown, the user starts the holiday mode and sets the number of holiday days Dv and the water temperature Tva during the holiday. Exemplarily, Tva defaults to 15°C and can be set between the temperature range of 15-20°C; the setting range of Dv is 1-365 days. The water heater defaults to the fresh air and hot water mode one day before the end of the holiday Dv, so that the user can have a fresh air environment and a suitable hot water temperature after returning home. First, determine whether to start the cold recovery mode based on the ambient temperature Tam of the environment in which the water heater is located. If Tam≤Test, that is, during the non-summer high temperature period, the water heater starts the fan first, enters the fresh air mode to introduce fresh air, the outdoor valve is opened, and the fresh air introduction time t defaults to tH, that is, the fan is running in a high position, and at the same time, the sterilization module of the indoor air outlet is turned on. Among them, tH can be set according to actual needs. When the fresh air introduction time is reached, the indoor valve is closed, the fresh air introduction ends, the water heater enters the mixed mode for sterilization, and after the sterilization is completed, it returns to the temperature setting state before the holiday. If Tam>Test, that is, when Tam shows that it is in the high temperature period in summer, the indoor valve is opened, and the water heater starts the mixed mode for sterilization. At this time, the heat pump is in working state, and the exhaust is cold air, which can enter the room through the indoor air outlet, lowering the indoor ambient temperature, which is conducive to the user having a better temperature experience after returning home. At the same time, the sterilization module of the indoor air outlet is turned on. After the water heater's mixed mode sterilization is completed, it returns to the temperature setting state before the end of the holiday.
