[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0053] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0054] The present application provides a control method for a multifunctional water heater and a multifunctional water heater. Before describing the technical solution provided by the present application, the piping structure of the multifunctional water heater to which the control method for a multifunctional water heater provided by the present application can be applied is first roughly described.

[0055] Figure 1A schematic diagram of a multifunctional water heater pipeline to which a control method for a multifunctional water heater provided by the present application can be applied, referring to Figure 1 In this application, the multifunctional water heater includes at least a plurality of working modules and peripheral devices. Figure 1 As shown, the peripheral equipment of the multifunctional water heater includes a fan coil, a floor heating coil and a hot water tank, wherein the fan coil is used to realize the cooling function, the floor heating coil is used to realize the heating function, and the hot water tank is used to realize the hot water making function.

[0056] Each working module is connected to the peripheral equipment through a three-way valve and a two-way valve. The working module is used to circulate refrigerant for these peripheral equipment so that the peripheral equipment can realize its corresponding function. In some practical application scenarios, the working module may specifically include compressors, radiators, condensers and other equipment for heat exchange.

[0057] like Figure 1 As shown, by controlling the connection direction of the three-way valve, it is possible to control whether the current working module provides circulating refrigerant for the hot water tank, and further control whether the working module is used to realize the hot water function of the multi-function water heater. By controlling the connection direction of the three-way valve and the switch state of the two-way valve, it is possible to control whether the current working module provides circulating refrigerant for the fan coil or for the floor heating coil, and further control whether the working module is used to realize the cooling function of the multi-function water heater or the heating function of the multi-function water heater.

[0058] It can be understood that the number of working modules currently providing circulating refrigerant for a certain peripheral device determines the working conditions of the corresponding functions of the peripheral device. If the number of working modules providing circulating refrigerant for the peripheral device is more, the operating efficiency of the corresponding functions of the peripheral device will be higher. Conversely, if the number of working modules providing circulating refrigerant for the peripheral device is smaller, the operating efficiency of the corresponding functions of the peripheral device will be lower.

[0059] In actual application, when the user control settings are as above Figure 1 When a multifunctional water heater with the pipeline shown in the figure is used, if the user controls the multifunctional water heater to give priority to a certain function, it is necessary to control the multiple working modules in the multifunctional water heater, reasonably allocate the number of working modules that provide circulating refrigerant for different peripheral devices, give priority to meeting the user's needs, and ensure that other needs other than the user's needs can be met. For this reason, a control method for a multifunctional water heater is needed to achieve a reasonable allocation of multiple working modules, on the premise of giving priority to meeting the user's needs, while ensuring that other needs other than the user's needs can be better met.

[0060] Figure 2 A flow chart of a control method for a multifunctional water heater provided in an embodiment of the present application, referring to Figure 2 The control method of a multifunctional water heater provided in the embodiment of the present application specifically includes the following steps:

[0061] S1: In response to a mode selection operation, determining a current operation mode of the multi-function water heater and determining a priority operation function in the current operation mode; wherein the current operation mode is an operation mode in which a hot water making function and a heating function are operated simultaneously or an operation mode in which a hot water making function and a cooling function are operated simultaneously, and the priority operation function is used to describe a function that a user desires to operate preferentially in the current operation mode;

[0062] Specifically, when the user controls the multifunctional water heater, a mode selection operation is performed, and based on the user's mode selection operation, the current operation mode of the multifunctional water heater is determined, and the priority operation function in the current operation mode is determined.

[0063] In a feasible embodiment of the present application, the mode selection operation can be performed on the wire controller of the multi-function water heater, that is, the user can determine the current operating mode of the multi-function water heater by selecting the corresponding mode button on the wire controller, and determine a certain operating function of the multi-function water heater that is expected to be implemented in the current operating mode in priority (that is, determine the priority operating function).

[0064] The current operation mode may be an operation mode in which the hot water making function and the heating function are operated simultaneously. In this operation mode, the working module of the multifunctional water heater provides circulating refrigerant for the hot water tank and the floor heating coil. The current operation mode may also be an operation mode in which the hot water making function and the cooling function are operated simultaneously. In this operation mode, the working module of the multifunctional water heater provides circulating refrigerant for the hot water tank and the fan coil. It is understandable that the multifunctional water heater cannot realize the operation mode in which the heating function and the cooling function are operated simultaneously. On the one hand, the operation mode in which the heating function and the cooling function are operated simultaneously is meaningless in actual application scenarios. On the other hand, based on Figure 1 The piping schematic diagram provided shows that since the switch state of the two-way valve can only be open or closed, the working module can only provide circulating refrigerant for any one peripheral device in the floor heating coil or fan coil.

[0065] The priority operation function is used to describe the function that the user expects to run first in the current operation mode. When the multi-function water heater runs two operation functions at the same time, the user can set one of the operation functions to be satisfied first, and the operation function that needs to be satisfied first is the priority operation function. For example, the current operation mode is the operation mode in which the hot water making function and the cooling function are running at the same time. If the user wants to take a hot bath, the hot water making function can be set as the priority operation function.

[0066] S2: Acquire a first working temperature and a second working temperature; wherein the first working temperature is used to describe the working condition of the hot water function, and the second working temperature is used to describe the working condition of the heating function / cooling function;

[0067] Specifically, after determining the current operating mode and the priority operating function under the current operating mode, the first working temperature and the second working temperature are obtained, the first working temperature is used to describe the working condition of the hot water making function, and the second working temperature is used to describe the working condition of the heating function / cooling function.

[0068] In a feasible embodiment of the present application, the first working temperature may be the outlet water temperature of the hot water tank, and the second working temperature may be the outlet water temperature of the floor heating coil or the outlet water temperature of the fan coil. It is understandable that when the second working temperature is the outlet water temperature of the floor heating coil, the working condition of the heating function can be described, and when the second working temperature is the outlet water temperature of the fan coil, the working condition of the cooling function can be described.

[0069] Therefore, when the current operating mode of the multi-function water heater is a mode in which both the hot water making function and the heating function are operated simultaneously, the second operating temperature is the water outlet temperature of the floor heating coil; when the current operating mode of the multi-function water heater is a mode in which both the hot water making function and the cooling function are operated simultaneously, the second operating temperature is the water outlet temperature of the fan coil.

[0070] S3: Allocating a first quantity to all the working modules according to the current operating mode, the priority operating function under the current operating mode, the first operating temperature, and the second operating temperature, so that the working modules preferentially satisfy the priority operating function;

[0071] Specifically, since the priority operation function describes the function that the user expects to run first in the current operation mode, the first working temperature describes the working condition of the hot water making function, and the second working temperature is used to describe the working condition of the heating function / cooling function, all working modules are allocated according to the current operation mode, the priority operation function in the current operation mode, the first working temperature and the second working temperature. In fact, all working modules are allocated based on user needs and actual operation conditions.

[0072] In a feasible embodiment of the present application, when the priority operation function is the hot water production function, a first quantity allocation is performed on all the working modules according to the current operation mode, the priority operation function under the current operation mode, the first working temperature and the second working temperature, including:

[0073] Calculating a first temperature difference between a first operating temperature and a first target temperature, and calculating a second temperature difference between a second operating temperature and a second target temperature; wherein the first target temperature is a target temperature of a hot water function, and the second target temperature is a target temperature of a heating function or a cooling function;

[0074] The number of working modules that currently meet the priority operation function is calculated by the first allocation formula; wherein the first allocation formula is:

[0075]

[0076] Among them, N1 is the number of working modules that currently meet the priority operation function calculated by the first allocation formula, N2 is the number of working modules that currently meet other operation functions calculated by the first allocation formula, N is the number of all working modules, Δt1 is the first temperature difference, Δt2 is the second temperature difference, K1 is the set first proportional coefficient, and f() is the rounding up function.

[0077] Specifically, the target temperature is the target value that needs to be achieved when running the function. The target temperature is set by the user. The target temperature includes a first target temperature and a second target temperature. The first target temperature is the target temperature of the hot water making function, which may be the water temperature to which the user expects the hot water to be heated. The second target temperature is the target temperature of the heating function or the cooling function, which may be the room temperature to which the user expects the environment to be adjusted.

[0078] Calculate the first temperature difference between the first working temperature and the first target temperature, and calculate the second temperature difference between the second working temperature and the second target temperature, substitute the first temperature difference and the second temperature difference into the first allocation formula, and determine the number of working modules that currently meet the priority operation function and the number of working modules that currently meet other operation functions.

[0079] The first temperature difference can be understood as the distance that the priority operation function is away from meeting user expectations. For the priority operation function, in order to better meet user needs, more working modules need to be set up to provide circulating refrigerant for the peripheral equipment corresponding to the priority operation function. Therefore, the first allocation formula can be understood as first allocating more working modules to provide circulating refrigerant for the peripheral equipment corresponding to the priority operation function. After allocating the working modules that provide circulating refrigerant for the peripheral equipment corresponding to the priority operation function, consider allocating the remaining working modules to provide circulating refrigerant for the peripheral equipment corresponding to other operation functions.

[0080] In the above embodiment, the priority operation function is the hot water making function, and the number of working modules initially allocated to the current hot water making function is calculated based on the first allocation formula, for example, a working modules satisfy the hot water making function, and the number of working modules initially allocated to the current cooling function / heating function is calculated, for example, b working modules satisfy the hot water making function. At this time, a working modules provide circulating refrigerant for the hot water tank, and b working modules provide circulating refrigerant for the floor heating coil or fan coil.

[0081] As the multifunctional water heater operates, the first temperature difference and the second temperature difference change, and the distance that the multifunctional water heater reaches the user's expectation also changes. In order to better balance the number of working modules that currently meet the priority operation function and the number of working modules that currently meet other operation functions during the operation of the multifunctional water heater, in a feasible embodiment of the present application, after calculating the number of working modules that currently meet the priority operation function by the first allocation formula, the method further includes:

[0082] When the current operation mode is a mode of simultaneously operating the hot water production function and the heating function, N1 and N2 are recalculated by the first allocation formula every time a preset time node is reached until the first operating temperature or the second operating temperature is greater than or equal to the temperature threshold.

[0083] Specifically, when the current operation mode is an operation mode in which both the hot water making function and the heating function are operated simultaneously, it can be known based on the above embodiments that the current priority operation function is the hot water making function, and the other operation function is the heating function. At this time, whenever the preset time node is reached, N1 and N2 can continue to be recalculated according to the first allocation formula, and the number of working modules that meet the hot water making function and the number of working modules that meet the heating function are reallocated through the calculated new values ​​of N1 and N2. By reallocating at the preset time node, the number of working modules that meet the hot water making function and the number of working modules that meet the heating function can be allocated in combination with the real-time operation of the multi-function water heater (reflected in the change of the first temperature difference and the second temperature difference).

[0084] In a feasible embodiment of the present application, reallocation may be performed every 30 minutes.

[0085] Since it is more difficult to assign the working module from the peripheral equipment corresponding to the hot water making function to the peripheral equipment corresponding to the cooling function than to assign the working module from the peripheral equipment corresponding to the hot water making function to the peripheral equipment corresponding to the heating function, when the current operating mode of the multi-function water heater is to simultaneously operate the hot water making function and the cooling function, it is necessary to consider the switching cost.

[0086] In a feasible embodiment of the present application, after calculating the number of working modules that currently meet the priority operation function by the first allocation formula, the method further includes:

[0087] In the case where the current operation mode is an operation mode in which the hot water production function and the cooling function are operated simultaneously, the number of working modules that currently meet the priority operation function and the number of working modules that currently meet other operation functions are calculated by the second allocation formula every time a preset time node is reached until the first operating temperature or the second operating temperature is greater than or equal to the temperature threshold; wherein the second allocation formula is:

[0088]

[0089] Among them, N1′ is the number of working modules that currently meet the priority operation function calculated by the second allocation formula, N2′ is the number of working modules that currently meet other operation functions calculated by the second allocation formula, and K2 is the set second proportional coefficient.

[0090] Specifically, the first proportional coefficient is used to describe the difficulty of switching between the hot water making function and the heating function, and the difficulty of switching between the hot water making function and the heating function is negatively correlated with the first proportional coefficient; the second proportional coefficient is used to describe the difficulty of switching between the hot water making function and the cooling function, and the difficulty of switching between the hot water making function and the cooling function is negatively correlated with the second proportional coefficient; the first proportional coefficient is smaller than the second proportional coefficient.

[0091] It can be seen that if the current operating mode is an operating mode in which the hot water making function and the cooling function are run simultaneously, then each time the preset time node is reached, the working module will not be allocated so frequently from the peripheral device corresponding to the hot water making function to the peripheral device corresponding to the cooling function.

[0092] Based on all the above embodiments, when the priority operation function is the hot water production function, the number of working modules that initially meet the hot water production function is first determined based on the first allocation formula, and the remaining working modules are used to meet other operation functions. After reaching the preset time node, the working modules are allocated again based on the current operation mode. It can be understood that the reallocation of the working modules can include multiple times, for example, a reallocation is performed every 30 minutes.

[0093] In a feasible embodiment of the present application, when the priority operation function is the cooling function or the heating function, a first quantity allocation is performed on all the working modules according to the current operation mode, the priority operation function under the current operation mode, the first working temperature and the second working temperature, including:

[0094] determining a first temperature difference and a second temperature difference;

[0095] The number of working modules that currently meet the priority operation function is calculated by the third allocation formula; wherein the third allocation formula is:

[0096]

[0097] Among them, N3 is the number of working modules that currently meet the priority operation function calculated by the third allocation formula, and N4 is the number of working modules that currently meet other operation functions calculated by the third allocation formula.

[0098] Specifically, when the priority operation function is the cooling function or the heating function, the majority of working modules are preferentially allocated to satisfy the cooling function or the heating function. The basic structure of the third allocation formula is similar to that of the first allocation formula, and the basic principle of the third allocation formula is similar to that of the first allocation formula, except that the positions of the first temperature difference and the second temperature difference in the formula are interchanged, so that the current priority is given to allocating working modules to provide circulating refrigerant for peripheral devices corresponding to the heating function or peripheral devices corresponding to the cooling function.

[0099] In a feasible embodiment of the present application, after calculating the number of working modules that currently meet the priority operation function by the third allocation formula, the method further includes:

[0100] When the priority operation function is the heating function, N3 and N4 are recalculated by the third allocation formula every time a preset time node is reached until the first operating temperature or the second operating temperature is greater than or equal to the temperature threshold.

[0101] Specifically, when the priority operating function is the heating function, the current operating mode is an operating mode in which the hot water making function and the heating function are simultaneously operated. Based on the same reallocation process as the above-mentioned embodiment in which the priority operating function is the hot water making function and the current operating mode is an operating mode in which the hot water making function and the heating function are simultaneously operated, N3 and N4 are recalculated when the preset time node is reached.

[0102] In a feasible embodiment of the present application, after calculating the number of working modules that currently meet the priority operation function by the third allocation formula, the method further includes:

[0103] When the priority operation function is the cooling function, the number of working modules that currently meet the priority operation function and the number of working modules that currently meet other operation functions are calculated by the fourth allocation formula every time a preset time node is reached until the first operating temperature or the second operating temperature is greater than or equal to the temperature threshold; wherein the fourth allocation formula is:

[0104]

[0105] Among them, N3′ is the number of working modules that currently meet the priority operation function calculated by the fourth allocation formula, and N4′ is the number of working modules that currently meet other operation functions calculated by the fourth allocation formula.

[0106] Specifically, when the priority operating function is the cooling function, the current operating mode is an operating mode in which both the hot water making function and the cooling function are simultaneously operated. Based on the same reallocation process as the above-mentioned embodiment in which the priority operating function is the hot water making function and the current operating mode is an operating mode in which both the hot water making function and the cooling function are simultaneously operated, considering the difficulty of switching between the hot water making mode and the cooling mode, the number of working modules that currently meet the hot water making function and the number of working modules that currently meet the cooling function are recalculated through the fourth allocation formula when the preset time node is reached.

[0107] S4: When the first operating temperature or the second operating temperature is greater than or equal to a preset temperature threshold, a second number allocation is performed on all the operating modules according to the current operating mode, the priority operating function under the current operating mode, the first operating temperature, and the second operating temperature, so that the operating modules simultaneously meet the priority operating function and other operating functions under the current operating mode;

[0108] Specifically, in the aforementioned steps, more working modules are allocated to peripheral devices corresponding to the priority operation functions, so that the user needs are fully met in the above operation stage. When the first operating temperature or the second operating temperature is greater than or equal to the preset temperature threshold, more working modules need to be allocated to meet other user needs, so that the multi-functional water heater can operate more evenly.

[0109] In a feasible embodiment of the present application, the preset temperature threshold can be set as P% of the first target temperature, or P% of the second target temperature. In some practical applications, P is 10. It can be understood that if the first operating temperature is used as the basis for judging whether the second quantity allocation is required, the preset temperature threshold is P% of the first target temperature. If the second operating temperature is used as the basis for judging whether the second quantity allocation is required, the preset temperature threshold is P% of the second target temperature.

[0110] In a feasible embodiment of the present application, a second quantity allocation is performed on all working modules according to the current operating mode, the priority operating function in the current operating mode, the first operating temperature, and the second operating temperature, including:

[0111] The first operating time is determined according to the number of working modules that currently meet the hot water function, and the second operating time is determined according to the number of working modules that currently meet the heating function / cooling function; wherein the first operating time is the time required for the first operating temperature to reach the first target temperature, and the second operating time is the time required for the second operating temperature to reach the second target temperature;

[0112] The number of working modules that meet the hot water function is recalculated by the fifth allocation formula, and the number of working modules that meet the heating function / cooling function is calculated; wherein the fifth allocation formula is:

[0113]

[0114] Among them, N5 is the number of working modules that meet the hot water function recalculated by the fifth allocation formula, and N6 is the number of working modules that meet the heating function / cooling function recalculated by the third allocation formula.

[0115] Specifically, the first operating time is the time required for the first working temperature to reach the first target temperature, and the second operating time is the time required for the second working temperature to reach the second target temperature. The first operating time is determined according to the number of working modules that currently meet the hot water making function, and the second operating time is determined according to the number of working modules that currently meet the heating function / cooling function.

[0116] In this embodiment, it can be determined how long it will take to reach the target temperature if the current allocation method is maintained, and the working modules are reallocated by the first operating time and the second operating time, so that the multi-functional water heater can operate in a more balanced manner after meeting user needs.

[0117] Through the technical solution provided by the embodiment of the present application, the user needs are described with the current operating mode and the priority operating function under the current operating mode, and the actual operating conditions of each operating function are described with the first operating temperature and the second operating temperature. The first quantity is allocated to all working modules with reference to the current operating mode, the priority operating function under the current operating mode, the first operating temperature and the second operating temperature, while considering the user needs and the actual operating conditions of each operating function, and giving priority to meeting the user needs. When the first operating temperature or the second operating temperature is greater than or equal to the preset temperature threshold, it means that the current user needs are basically met, and the second quantity is allocated to all working modules according to the current operating mode, the priority operating function under the current operating mode, the first operating temperature and the second operating temperature, and the working modules are allocated more evenly, while meeting the user needs and other needs.

[0118] Through the technical solution provided in the embodiment of the present application, a reasonable allocation of multiple working modules is achieved, and on the premise of giving priority to meeting user needs, it is ensured that other needs except user needs can be better met.
