[0048] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0049] A water circuit system with a hot water tank, such as an air source heat pump water heater, a solar water heater, etc. The hot water tank plays a role in storage. Compared with water heaters without a storage tank, the inlet and outlet of the hot water tank have no direct relationship in terms of pressure and flow. A water heater without a storage tank can increase the pressure of the outlet water only by a circulation pump or water supply pressure installed at the inlet position, while a hot water tank requires a booster pump at the outlet to achieve pressure increase. In order to avoid too long waiting time for hot water and achieve the effect of "zero cold water", a circulation pump is also required at the inlet of the hot water tank. This can simultaneously achieve the functions of hot water pressure increase and hot water circulation, as Figure 1 shown.

[0050] However, this implementation method has problems of high cost and high installation space requirements, is not suitable for household use, and the booster pump and the circulation pump are two independent devices, and the two cannot work together and may even affect each other.

[0051] This application provides a control method for a circulation and boosting integrated pump, which can be applied to the hot water tank scenario and use a single pump to achieve boosting and circulation operations based on user control.

[0052] In one embodiment, the circulation and boosting integrated pump 11 is installed as Figure 2 shown. The hot water tank can perform temperature control based on its own control program. The hot water tank and the hot water circulation pipeline 12 form a water circuit circulation. A water user is provided on the hot water circulation pipeline 12. Taking the connection point of the water user as the boundary, the part between the water user and the outlet of the hot water tank is used as the hot water section 121 of the hot water circulation pipeline 12, and the part between the water user and the inlet of the hot water tank is used as the return water section 122 of the hot water circulation pipeline 12. The hot water tank and the water user can also be connected to a cold water pipeline for water supply, and a check valve is provided on the return water section 122.

[0053] The circulation and boosting integrated pump 11 (hereinafter referred to as the integrated pump) is arranged on the hot water section 121, and a controller 13 is arranged for mode control. The integrated pump is connected to the controller 13 as Figure 3 shown. The mode control includes a circulation mode and a boosting mode. The control instructions corresponding to each mode can be pre-stored in the memory 14. In the circulation mode, the controller 13 controls the operation of the integrated pump based on temperature induction. In the boosting mode, the controller 13 controls the operation of the integrated pump based on pressure induction.

[0054] In this embodiment, the control method is as Figure 4 shown and includes the following steps:

[0055] Step 201, in the shutdown state of the circulation and boosting integrated pump 11, based on the increase in the flow rate in the hot water circulation pipeline 12, determine the first water use of the water user and record the first water use duration.

[0056] In this embodiment, the "water usage" refers to the use of hot water in the hot water circulation pipeline 12.

[0057] The water flow rate in the hot water circulation pipeline 12 is sensed by a flow monitoring unit such as a water flow sensor 15. And the flow monitoring unit is arranged in the hot water section 121 of the hot water circulation pipeline 12. In the state where the integrated pump is stopped, the flow in the hot water section 121 is affected by the opening and closing of the water using device. When an increase in flow is detected, it indicates that there is a water usage behavior, and the water usage duration starts to be recorded. In this embodiment, the start time of the user's first water usage is the moment when the flow increase is detected, and the end time is when the flow returns to the value of 0 again.

[0058] Step 202, when the first water usage duration reaches the first duration threshold, execute the pressurization instruction; otherwise, delay and wait, and the delay waiting duration is the second duration threshold.

[0059] When it is determined that the user has turned on the water using device, if the water usage duration reaches the first duration threshold, such as 3 s, it can be considered that this water usage is a long - time water usage, and then the preset pressurization instruction can be executed to control the integrated pump to start, and by controlling the rotational speed of the integrated pump, the water pressure in the hot water circulation pipeline 12 is adjusted until the set pressurization pressure is reached and maintained. A corresponding water pressure monitoring unit, such as a pressure sensor 16, can be arranged at the outlet of the integrated pump.

[0060] If the water flow exists for a short time but disappears before 3 s, it enters the delay waiting process and waits for the second duration threshold, such as 3 s, for the purpose of confirming whether the user has a second water usage.

[0061] Step 203, based on the flow monitoring during the delay waiting period, determine whether there is a second water usage. If there is, start recording the second water usage duration. Similarly, the start time of the second water usage is still the moment when the flow increase is detected, and the end time is when the flow is monitored to return to the value of 0.

[0062] Step 204, judge the second water usage duration.

[0063] When the second water usage duration reaches the third duration threshold, it is still considered that the user expects to have a long - time water usage, and then the pressurization mode can be started. The third duration threshold can be the same as the first duration threshold, such as 3 s. If the second water usage does not last for 3 s, it is judged that the user starts the hot water circulation through the water control method, and the controller 13 responds to this water control action and executes the circulation instruction.

[0064] In the circulation mode, the controller 13 controls the integrated pump to operate at the maximum working rotational speed, completes the hot water circulation in the shortest time, quickly discharges the cold water in the hot water circulation pipeline 12, and monitors the temperature through the temperature sensor 17 arranged on the return water section 122. When the temperature value reaches the set target temperature, the operation can be stopped.

[0065] In the above embodiments, based on flow monitoring, it is determined whether the user has a water usage behavior, and in response to different water usage behaviors of the user, a single pump is used to perform corresponding boosting control or circulation control, flexibly meeting various needs of the user (such as scenarios where the user hopes for direct boosting or direct hot water circulation).

[0066] As Figure 5 shown in the process schematic diagram, it shows the process of determining whether to enter the boosting mode or the circulation mode based on duration in one embodiment.

[0067] In one embodiment, the switching process of switching from the circulation mode to the boosting mode is also disclosed.

[0068] Specifically, as Figure 6 shown, in the circulation mode, if the opening of the water using device is detected, it is switched to the boosting mode. In one implementation, the real-time water flow rate after executing the circulation instruction is obtained through the flow sensor 15, and a threshold judgment is performed. The mode switching flow rate can be set as the judgment benchmark in the controller 13. The mode switching flow rate is, for example, 1.1 times the normal circulation flow rate. If the real-time water flow rate reaches or exceeds this mode switching flow rate, the integrated pump is switched to the boosting mode to execute the boosting instruction.

[0069] In the above embodiments, the exit processes of the circulation mode and the boosting mode are also disclosed, as Figure 6 shown.

[0070] Specifically, the circulation mode exits based on temperature judgment. For example, as described above, the water temperature is monitored through the temperature sensor 17 in the return water section 122. When the water temperature reaches the preset circulation shutdown temperature, the integrated pump can be controlled to stop.

[0071] The exit conditions of the boosting mode are different based on different entry conditions. Exemplarily as follows:

[0072] 1. If directly entering the boosting mode due to the duration of the first water usage or the second water usage reaching the corresponding threshold, it is necessary to sample and obtain the first flow rate value F1 before boosting. After boosting, sample again to obtain the second flow rate value F2 when the water pressure reaches the set boosting pressure. Judge the real-time water flow rate after boosting. If the real-time water flow rate after boosting becomes F2 - F1, it is considered that the user has closed the water using device, and then the boosting mode is exited, and the integrated pump is controlled to stop.

[0073] 2. If first entering the circulation mode and then switching to the boosting mode through the aforementioned switching process, it is necessary to obtain the first pump speed n1 when executing the circulation instruction. In this implementation, the first pump speed is the maximum working speed. At the same time, sample and obtain the third flow rate value F3 when executing the circulation instruction;

[0074] After entering the pressurization mode, when the set pressurization pressure is reached, the rotational speed n2 of the second pump is sampled, and then the proportional threshold p = n2 / n1 is obtained.

[0075] After switching to the pressurization mode, the real-time water flow rate in the pressurization mode is obtained. When the real-time water flow rate becomes p*F3, it can be considered that the user has turned off the water appliance, and then the integrated pump is controlled to stop.

[0076] In the above embodiment, corresponding exit conditions are set for different modes, and the exit control is more accurate.

[0077] In one embodiment, a process for automatically starting the circulation mode is further provided, which can ensure that the user does not need to manually start the circulation mode anymore, but can directly use hot water.

[0078] Exemplarily, each time the circulation mode is entered, the start time of executing the circulation instruction is obtained, and all the start times within a certain period, such as 10 days, are counted to determine the general time points when the user commonly uses hot water, which are defined as the circulation execution times. Every day when the current time reaches the circulation execution time, the circulation instruction is automatically executed.

[0079] The statistical method is, for example, to divide each day into multiple time intervals, and separately count the total number of times the circulation mode is started within each time interval in 10 days. The interval with the total number reaching a certain number threshold is determined as the target interval, and the front-end value of the target interval is determined as the circulation execution time.

[0080] It should be understood that although Figure 4 the steps in the flowchart are shown in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise clearly stated in this article, there is no strict order limit for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 4 at least a part of the steps in

[0081] In one embodiment, as Figure 7 shown, a control device for a circulation pressurization integrated pump is provided, which is applied to a hot water circulation pipeline connected to a hot water tank. Among them, a water appliance is provided on the hot water circulation pipeline, the hot water section of the hot water circulation pipeline is connected to the water outlet of the hot water tank, and the return water section is connected to the water inlet of the hot water tank; the circulation pressurization integrated pump is arranged on the hot water section, and a check valve is arranged on the return water section;

[0082] The device includes: a flow rate monitoring module 301, a timing module 302, a judgment module 303, and an execution module 304, where:

[0083] The flow rate monitoring module 301, such as a flow sensor, is used to obtain the water flow rate in the hot water section;

[0084] The timing module 302 is used to, when the circulating booster integrated pump is in a stopped state, determine the first water use of the water appliance based on the flow rate change in the hot water circulation pipeline, record the duration of the first water use; and when the duration of the first water use is less than the first duration threshold, delay and wait, and the delay waiting duration is the second duration threshold. If there is a second water use of the water appliance during the delay waiting period, record the duration of the second water use;

[0085] The judgment module 303 is used for duration judgment, including judging whether the duration of the first water use reaches the first duration threshold and whether the duration of the second water use reaches the third duration threshold;

[0086] The execution module 304 is used to, when the duration of the first water use reaches the first duration threshold, or when the duration of the second water use reaches the third duration threshold, execute a boosting instruction, or when the duration of the second water use does not reach the third duration threshold, execute a circulation instruction, such as controlling the circulating booster integrated pump to operate at the maximum working speed.

[0087] The above control device, in the stopped state of the integrated pump, relies on the flow monitoring result to judge whether there is user water use; at the first water use, if the duration reaches the first duration threshold and it is judged that the user needs long-term water use, then execute a boosting instruction to provide the user with boosting ability; if the duration does not reach the first duration threshold, then there is no need to start, but make a delay judgment to judge whether the user is performing a specific water control start action, that is, short-time second water use after short-time first water use. If there is a water control start action, then execute a circulation instruction to make the water circulate in the circulation pipeline to drain the cold water; by using the control device of the present application, the boosting and circulation functions of the hot water tank can be realized by using one pump device.

[0088] The control device further includes a water pressure monitoring module 305, such as a pressure sensor, which is used to obtain the water pressure data during the execution of the boosting instruction, and the execution module 304 of the controller controls the increase and decrease of the rotation speed of the circulating booster integrated pump to make the water pressure reach the set boosting pressure.

[0089] The flow rate monitoring module 301 also obtains the first flow rate value before boosting for the first water use or the second water use, and obtains the second flow rate value after boosting when the water pressure reaches the set boosting pressure. The judgment module 303 then judges whether the real-time water flow rate after boosting is the difference between the second flow rate value and the first flow rate value. If so, the execution module 304 controls the circulating booster integrated pump to stop.

[0090] The flow monitoring module 301 also obtains the real-time water flow after executing the circulation instruction, and the judgment module 303 judges whether the real-time water flow after executing the circulation instruction is greater than or equal to the mode switching flow. If so, the execution module 304 controls the integrated pump to switch from executing the circulation instruction to executing the pressurization instruction.

[0091] The device further includes a rotation speed acquisition module 306 that acquires the first pump rotation speed when executing the circulation instruction and the second pump rotation speed when executing the pressurization instruction.

[0092] The flow monitoring module 301 obtains the corresponding third flow value at the first pump rotation speed.

[0093] The execution module 304 determines a proportional threshold according to the ratio of the second pump rotation speed to the first pump rotation speed. When the value of the real-time water flow after the instruction switch is equal to the product of the third flow value and the proportional threshold, it controls the circulation and pressurization integrated pump to stop.

[0094] The timing module 302 also obtains the start time of executing the circulation instruction, and determines the circulation execution time according to the statistics of the start time within the statistical period. The execution module 304 then executes the circulation instruction when the current time reaches the circulation execution time.

[0095] For the specific limitations of the control device of the circulation and pressurization integrated pump, reference can be made to the limitations of the control method of the circulation and pressurization integrated pump in the above text, which will not be elaborated here. Each module in the above control device of the circulation and pressurization integrated pump can be implemented in whole or in part by software, hardware, and their combination. The above modules can be embedded in the processor in the computer device in the form of hardware or be independent of it, or can be stored in the memory in the computer device in the form of software, so as to facilitate the processor to call and execute the operations corresponding to the above modules.
