Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments herein without making any creative effort, shall fall within the scope of protection.

It should be noted that the terms "first," "second," and the like in the description and claims herein and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments herein described are capable of operation in sequences other than those illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, apparatus, article, or device that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or device.

The control system of the water outlet equipment in the embodiment of the specification can be applied to water outlet equipment such as top shower, shower head and faucet. It should be noted that, in the embodiments of the present specification, the water outlet apparatus with top spraying is described as an example, but those skilled in the art can understand that the water outlet apparatus with top spraying is merely exemplary; the control system and the control method of the water outlet device can also be applied to other water outlet devices such as a shower head, a faucet, the water outlet device on a bathtub, the water outlet device on a toilet bowl and the like, and the control system and the control method are not limited in this specification and can be selected according to needs.

In view of the fact that the distance between the top spray and the top spray shunt valve of the existing water outlet equipment with the top spray is long, residual water can be formed in a pipeline between the top spray and the top spray shunt valve after each shower, and low-temperature residual water can be easily and directly sprayed to a user when the user uses the top spray shower next time; and the pipeline between the heat source and the water outlet device is longer, after each shower, residual water is formed in the pipeline between the heat source and the water mixing valve of the water outlet device and the pipeline between the water mixing valve and the water diversion valve, the temperature of the residual water is lower, and the time for heating and mixing the water is required, so that a user needs to wait for several minutes before showering to discharge the residual water, and the problems of poor user experience and inconvenience in use exist.

As shown in fig. 1, the structure of the water outlet apparatus is schematically illustrated, and the water outlet apparatus includes a water mixing pipeline 10, a water mixing and draining pipeline 20, a residual water pipeline 30 and a control system as shown in fig. 4; one end of the residual water pipeline 30 is connected with a top spray 31 (namely a water using end), the other end is connected with the water mixing pipeline 10 through a top spray shunt valve 11 (namely a water using end shunt valve corresponding to the top spray), a top spray drain valve 32 is arranged on the residual water pipeline 30, and the top spray drain valve 32 is arranged between the top spray 31 and the top spray shunt valve 11. The mixing water pipeline 10 is connected with the mixing water drainage pipeline 20 through a mixing water drainage valve 21. The control system comprises the top-spraying water diversion valve 11, the top-spraying water drainage valve 32, the water mixing water drainage valve 21 and a controller 70 electrically connected with the above components.

When a top spray water command is received, the controller 70 of the control system can control the top spray drain valve 32 to open to drain the residual water in the residual water line 30; and judging whether the temperature of the mixed water reaches a set water temperature, wherein when the temperature of the mixed water does not reach the set water temperature, the controller 70 is used for closing the top spray water dividing valve 11 and controlling the water mixing and draining valve 21 to be opened so as to drain the mixed water in the mixed water draining pipeline 20; when the mixed water temperature reaches the set water temperature, the controller 70 can control the mixed water drain valve 21 and the top spray drain valve 32 to be closed and control the top spray water diversion valve 11 to be opened for top spray shower, so that the user experience is improved. And, for the artifical water mixing's of judging the temperature and discharging residual water and not reaching the settlement temperature that traditional water outlet device adopted mode, the control system of water outlet device that this application specification embodiment provided can be when the temperature reaches the user and sets for automatic water, and is more convenient, high-efficient and accurate.

It should be noted that, in this specification, the order between the step of discharging the residual water and the step of discharging the mixed water that does not reach the set water temperature is not limited, and the residual water may be discharged first and then the mixed water that does not reach the set water temperature may be discharged; or may be performed simultaneously. In addition, in an actual use scenario, since the pipe between the top spray water dividing valve 11 and the top spray 31 is relatively short, it can be considered that the amount of residual water in the residual water pipe 30 is less than the amount of mixed water in the mixed water pipe 10 that does not reach the set water temperature, and therefore, when the mixed water temperature reaches the set water temperature, that is, when the mixed water that does not reach the set water temperature is discharged, it can be considered that the residual water is also discharged. And when the residual water is completely discharged and the temperature of the mixed water reaches the set water temperature, controlling the mixed water drain valve and the top-spraying drain valve to be closed and controlling the top-spraying water-splitting valve to be opened so as to carry out top-spraying shower. In the embodiment, when the top spray water discharge valve 32 is opened, the residual water in the residual water line 30 can be discharged by its own weight.

In the embodiments of the present disclosure, the controller 70 may be a single chip, a Microprocessor (MCU), a Digital Signal Processor (DSP), or a control board integrated with the controller. The electrical connection may be a wired electrical connection implemented by a control line, a data line, or the like, or may be a wireless communication connection established between the two parties by a wireless communication technique.

The "electrical connection" appearing in other parts of the specification may refer to this explanation and will not be described in detail. As shown in fig. 1 to 4, the water outlet apparatus further includes a water mixing device 40, a cold water inlet pipeline 50 and a hot water inlet pipeline, the water mixing device 40 is electrically connected to the controller 70, and the water mixing device 40 can mix water under the control of the controller 70. The water mixing device 40 comprises a cold water inlet end connected to the cold water inlet pipeline 50 and a hot water inlet end connected to the hot water inlet pipeline 60, and the water outlet end of the water mixing device 40 is connected to the water mixing pipeline 10. The mixing device 40 is capable of mixing cold water and hot water, so that mixed water with a water temperature lower than the hot water temperature and higher than the cold water temperature is formed and is delivered into the mixing pipeline 10. In some possible embodiments, the water mixing device 40 may be a water mixing motor or an electric water mixing valve, etc.

In the embodiments of the present disclosure, the cold water may be water from a tap water pipeline, that is, the cold water inlet pipeline 50 may be in communication with the tap water pipeline; hot water is water (typically at a higher temperature than cold water) heated by a heat source and delivered through the hot water inlet line 60. Wherein, the heat source can be electric water heater, gas heater, solar water heater etc. facility equipment.

The cold water inlet pipeline 50 is also provided with a cold water temperature sensor 51 which is used for collecting the temperature of cold water in the cold water inlet pipeline 50; the hot water inlet pipeline 60 is also provided with a hot water temperature sensor 61 which is used for collecting the temperature of the hot water in the hot water inlet pipeline 60; the controller 70 is also electrically connected to the cold water temperature sensor 51 and the hot water temperature sensor 61, so as to send a temperature control signal to the water mixing device 40 according to the cold water temperature and the hot water temperature, so as to enable the mixed water temperature to reach the set water temperature.

In some embodiments, the controller 70 sends a temperature control signal to the water mixing device 40 according to the cold water temperature and the hot water temperature to make the mixed water temperature reach the set water temperature, which may be:

the controller 70 determines a cold-hot water flow rate ratio required for making the mixed water temperature reach the set water temperature according to the cold water temperature and the hot water temperature; i.e. the mixing ratio of hot water to cold water at the mixing device 40.

And sending a flow regulating signal to the water mixing device 40 according to the cold-hot water flow ratio.

The mixed water temperature is in a direct proportion relation with the hot water flow and the hot water temperature, the mixed water temperature is higher when the hot water flow is higher under a certain condition of the hot water temperature, and the mixed water temperature is higher when the hot water temperature is higher under a certain condition of the hot water flow; in contrast, the temperature of the mixed water is inversely proportional to the flow rate of the cold water and the temperature of the cold water. Therefore, when the device is in actual use, hot water and cold water can be mixed in different proportions according to the determined temperature of the hot water and the determined temperature of the cold water, so as to obtain mixed water with different temperatures. According to the principle, a mapping relation curve between the mixing proportion and the mixed water temperature under any combination of hot water temperature and cold water temperature can be generated in advance. Therefore, the cold-hot water flow ratio for enabling the mixed water temperature to reach the water temperature set by the user can be matched according to the hot water temperature, the cold water temperature and the mapping relation curve measured in real time, and the corresponding flow regulation and control signal is sent to the water mixing device 40, so that the mixed water temperature can be quickly and accurately regulated.

In some embodiments, the sending of the flow control signal to the water mixing device 40 according to the cold-hot water flow ratio may be implemented based on a PID (proportional Integral Differential) algorithm adjustment. Taking the water mixing motor as an example, when the control system is powered on for initialization, the controller 70 controls the water mixing motor to reset to an initial position (for example, the water mixing motor in the initial position can make the cold water flow and the hot water flow equal), so as to regulate the step number of the water mixing motor based on the PID algorithm based on the water mixing water temperature, the cold water temperature and the hot water temperature collected in real time or at regular time, and adjust the flow ratio of the cold water and the hot water at the water mixing motor. If the collected water mixing temperature is higher than the set water temperature, calculating the difference value of the collected water mixing temperature and the set water temperature to obtain the first step number of the water mixing motor so as to increase the cold water flow; if the water mixing temperature is lower than the set water temperature, calculating a second step number (the rotation direction of the second step number is opposite to that of the first step number) of the water mixing motor to increase the hot water flow; if the temperature of the mixed water is equal to the set water temperature, the difference value of the mixed water and the set water temperature is calculated to be 0, namely the water mixing motor is kept at the current position.

In the embodiments of the present description, the phrase "the mixed water temperature is equal to the set water temperature" and "the mixed water temperature reaches the set water temperature" means that the mixed water temperature is the same as or substantially the same as the set water temperature; the basically same means that the difference between the mixed water temperature and the set water temperature is less than or equal to a preset allowable range (for example, less than or equal to 1 ℃).

In order to realize accurate control of the temperature of the mixed water and improve the user experience, in some preferred embodiments, the control system of the water outlet apparatus further includes:

an ambient temperature sensor 80 for acquiring an ambient temperature of an environment in which the water mixing pipeline 10 is located;

the controller 70 is electrically connected to the ambient temperature sensor 80, and the controller 70 is further configured to send a temperature control signal to the water mixing device 40 according to the ambient temperature, the cold water temperature, and the hot water temperature, so that the mixed water temperature reaches the set water temperature.

Because water admixing device 40 and top spout and may have a certain distance between the 31, water admixing device 40 department mixes water through muddy water pipeline 10 circulation to the top spout 31 when locating the play water, because there is heat conduction phenomenon to make its temperature probably reduce to some extent, be unfavorable for user's use to experience. Therefore, in the present specification, it is preferable to compensate the set water temperature based on the ambient temperature so that the outlet water temperature at the top nozzle 31 is the set water temperature of the user.

In some specific embodiments, the controller sends a temperature control signal to the water mixing device according to the ambient temperature, the cold water temperature and the hot water temperature, so as to enable the mixed water temperature to reach the set water temperature, and may be:

calculating a compensation temperature according to the environment temperature, wherein the compensation temperature is inversely related to the environment temperature; that is, the lower the ambient temperature, the higher the compensation for the set water temperature.

Determining the actual water mixing temperature of the water mixing device according to the compensation temperature and the set water temperature; the actual mixed water temperature, that is, the outlet water temperature obtained by the user side, may be the sum of the set water temperature and the compensation temperature.

In some feasible embodiments, a compensation relation table of the ambient temperature to the set water temperature may be generated in advance, so that in actual use, the compensation temperature can be matched quickly and accurately according to the ambient temperature obtained in real time or at regular time and the compensation relation table, and further the cold-hot water flow ratio of the water mixing device is adjusted.

As shown in table 1 below, a first corresponding relationship table of the ambient temperature and the compensation temperature is provided for the embodiments of the present specification.

TABLE 1

Ambient temperature (Ta)	Compensating for temperature	Actual water temperature (T) _inctr )
			Ta≤0℃	△t ₁₁	T _in +△t ₁₁
0℃<Ta≤10℃	△t ₂₁	T _in +△t ₂₁
			10℃<Ta≤25℃	△t ₃₁	T _in +△t ₃₁
25℃<Ta≤32℃	△t ₄₁	T _in +△t ₄₁
			Ta>32℃	△t ₅₁	T _in +△t ₅₁

In Table 1, T _in To set the water temperature, T _inctr For an actual mixed water temperature, the relationship between the two may be: t is _inctr ＝T _in +△t _i1 Wherein i is the interval of the ith in which the ambient temperature (Ta) is present, Δ t _i1 That is, the compensation temperature corresponding to the interval in which the ambient temperature is located in table 1. Each compensation temperature corresponding to each environmental temperature interval has the following constraint relation:

△t ₁₁ >△t ₂₁ >△t ₃₁ >△t ₄₁ >△t ₅₁ ，

and Δ t ₅₁ ≥0℃。

It can be seen that the compensation temperature is higher as the ambient temperature is lower. Illustratively, if the currently detected ambient temperature is 8 ℃, then the current ambient temperature falls to 0 ℃ as can be seen from the first correspondence table shown in table 1<Within the interval of Ta less than or equal to 10 ℃, the compensation temperature delta t corresponding to the environment temperature of 8 ℃ can be matched ₂₁ If the actual mixed water temperature is T _in +△t ₂₁ 。

This specification embodiment carries out temperature compensation through the temperature of setting for to water admixing device department, has compensatied the calorific loss of mixing water in the circulation in-process for the play water in user side reaches user's the temperature of setting for as far as, has improved user's use and has experienced.

In another possible embodiment, the controller may also calculate the compensation temperature according to the set water temperature, so as to obtain the actual mixed water temperature. As shown in table 2, is a second corresponding relationship table of the set water temperature and the compensation temperature.

TABLE 2

Set water temperature (T) _in )	Compensating for temperature	Actual water temperature (T) _inctr )
			T _in >50℃	△t ₁₂	T _in +△t ₁₂
47℃<T _in ≤50℃	△t ₂₂	T _in +△t ₂₂
			42℃<T _in ≤47℃	△t ₃₂	T _in +△t ₃₂
36℃<T _in ≤42℃	△t ₄₂	T _in +△t ₄₂
			T _in ≤36℃	△t ₅₂	T _in +△t ₅₂

In table 2, the relationship between the actual mixed water temperature and the set water temperature may be: t is _inctr ＝T _in +△t _i2 Wherein Δ t _i2 The compensation temperature corresponding to the interval in which the water temperature is set in table 2. The compensation temperatures corresponding to the set water temperature intervals have the following constraint relationship:

△t ₁₂ >△t ₂₂ >△t ₃₂ >△t ₄₂ >△t ₅₂ ，

and Δ t ₅₂ ≥0℃。

According to the constraint relation, the following steps are carried out: the higher the set water temperature, the greater the compensation temperature for the set water temperature. The reason is that the temperature difference between the set water temperature and the ambient temperature is larger when the ambient temperature is fixed, so that the heat conduction phenomenon is more obvious, and the heat loss of the mixed water is serious.

Therefore, in another possible embodiment, the controller may also calculate the compensation temperature according to the difference between the set water temperature and the ambient temperature, so as to more accurately regulate and control the actual mixed water temperature and improve the user experience.

As shown in fig. 2, the control system of the water outlet apparatus may further include a mixing temperature sensor 14, the mixing temperature sensor 14 is electrically connected to the controller 70, and the mixing temperature sensor 14 is configured to collect a mixing water temperature of the mixing pipeline.

Preferably, the mixed water temperature sensor 14 can be arranged on the side of the mixed water pipeline 10 close to the top jet 31 (i.e. close to the user), so that the mixed water temperature and the set water temperature can be controlled more accurately when the water outlet end is controlled to be water outlet, and finally the water temperature of the water outlet at the top jet 31 is closer to or even equal to the set water temperature of the user, which is beneficial to improving the user experience.

Furthermore, the water outlet device may further include a thermostatic valve core (not shown in the figure), the thermostatic valve core is provided with a temperature sensing component, and when the water in the water mixing pipeline does not reach the set water temperature, the temperature sensing component shrinks the thermostatic valve core to be in a normally closed state, so that the water in the water mixing pipeline which does not reach the set water temperature is discharged from the water mixing water generating valve; when the temperature of the mixed water reaches the set temperature, the temperature sensing part is heated to expand so that the mixed water pipeline is in an open state, and the mixed water reaching the set temperature flows out from the water using end or the water outlet end to meet the water using requirement of a user. The temperature sensing component can be a shape memory alloy spring, so that the shape memory alloy spring is used as a temperature sensing element and has the function of pushing the piston to adjust the mixing ratio of cold water and hot water, and the mixed water can also pass through the spring, so that the structure of the thermostatic valve core becomes more compact. Further, the thermostatic valve core can be arranged at a water using end and/or a water outlet end, namely, the top shower 31 and/or the handheld shower head.

In the embodiment shown in fig. 2, the water outlet apparatus further includes a water outlet shunt valve 12 connected to the mixing pipeline 10, and the water outlet shunt valve 12 connects the mixing pipeline 10 and the water outlet 13 to control the water outlet at the water outlet 13.

A water tap (not shown) in a kitchen, a toilet, etc. may be further included to satisfy various water demands of the user. The outlet shunt valve 12 may include a hand-held shower shunt valve 121 and a lower outlet shunt valve 122, respectively, and may also include a faucet shunt valve (not shown). While the above is merely an exemplary classification, in some other embodiments, the top spray 31 may be generalized within the outlet end 13 and the top spray diverter valve 11 may be generalized within the outlet end diverter valve 12.

Thereby avoiding the water which does not reach the set water temperature from splashing to the user to cause poor user experience.

Referring to fig. 11 and 12, wherein fig. 11 shows a schematic diagram of a change of an outlet water temperature of a water outlet apparatus in the prior art; FIG. 12 is a schematic diagram illustrating a variation of an outlet water temperature of a water outlet apparatus provided in an embodiment of the present disclosure; the water outlet temperature refers to the water temperature of water discharged from the top shower, the handheld shower head, the lower water outlet and the faucet. As can be seen from comparing fig. 11 and 12, based on the control device of the water outlet apparatus provided in the embodiment of the present disclosure and the compensation logic for the set water temperature, the outlet water temperature of the water outlet apparatus can be more stably maintained near the set water temperature, which is beneficial to improving the user experience.

In some possible embodiments, as shown in fig. 3, to save piping costs for a simplified construction, the mixing and draining piping 20 is connected to the lower outlet 132 in the outlet end, so that mixed water that does not reach the set water temperature can be discharged from the lower outlet 132. It will be appreciated by those skilled in the art that this is only one possible embodiment and in other embodiments, the mixing drain line 20 may be provided with a separate drain opening, as desired.

In other embodiments, the mixed water discharging pipeline 20 may be further connected to the cold water inlet pipeline 50, so as to recycle water that does not reach the set water temperature, which is beneficial to saving water resources.

In some preferred embodiments, the controller may be a low power controller that is in a sleep state during periods when not in use by a user to reduce power consumption.

Correspondingly, the control system may further include an open/close detection element (not shown in the figure), which is disposed on the top spray water diversion valve 11 and the water outlet end water diversion valve 12, and is used for detecting the open/close states of the top spray 31 and the water outlet end 13; the controller 70 is electrically connected to the open/close detection element, and when the top spray is received and/or the water outlet end is opened, the controller 70 is switched from a dormant state to a working state. And then the water mixing device is controlled to work according to the set water temperature and the mixed water temperature.

So, can make water outlet device only under the condition that the user needs the water, just discharge not reach under setting for the muddy water of temperature (need the top to spout under the condition of shower, still control the top and spout that the drain valve is opened with the residual water in the residual water pipeline of discharging) to can avoid wasting the water resource. That is, when the control device of the water outlet apparatus is powered on and initialized, the water mixing and draining valve 21, the top spraying and draining valve 32, the top spraying and water dividing valve 11 and the water outlet end water dividing valve 12 are all closed, so as to avoid the water drainage error.

The fault detection of the water outlet device can be performed according to the flow rate of the mixed water, for example, for indirectly and additionally detecting whether the water mixing device 40, each water dividing valve and the water mixing and draining valve 21 are damaged or not.

For example, in the case of normal water supply, if the flow sensor 15 detects that the water mixing flow is zero (or almost zero) within a specified time period after the top-spraying water dividing valve or the water outlet end water dividing valve is opened, the controller 70 may determine that the water mixing device 40 and/or the water dividing valve and/or the water mixing and draining valve 21 may have a fault, and the controller 70 may generate a fault alarm (for example, output a fault alarm such as a character or an icon through a display module of the water outlet apparatus) to remind a user of maintenance.

The power supply module can be a flyback isolation power supply or a lithium battery, so that the circuit structure of the control system can be simplified, and the cost is reduced. The lithium battery can be a lithium battery with a wireless charging function, so that charging is convenient, and the electricity utilization safety in wet environments such as kitchens, toilets and shower rooms is improved.

The specification also provides a control method applicable to the control system of the water outlet equipment, and particularly, the control method can be applied to the controller side of the control system of the water outlet equipment. The steps of the method for controlling a water outlet device as shown in fig. 5 are schematic diagrams, and the present specification provides the method operation steps as described in the embodiment or the flowchart, but more or less operation steps can be included based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution.

In some practical scenarios, it can be considered that when the mixed water that does not reach the set water temperature is discharged (when the mixed water temperature reaches the set water temperature), the residual water is also discharged, so that the determination step is simplified.

The steps of the control method for the water outlet device provided in the embodiments of the present specification are only one of the execution sequences of the steps, and do not represent a unique execution sequence. In actual execution, after the top spray of the water outlet device is used by a user each time (i.e., a signal indicating that the water outlet device is used is obtained), and on the premise of waiting for a period of time (e.g., 30 minutes), the top spray water drain valve and the water mixing water drain valve are kept closed, the top spray water drain valve is controlled to be opened (i.e., a closing signal is sent to the top spray water drain valve and a closing signal is sent to the top spray water drain valve), so as to drain residual water in a residual water pipeline. Make when the user uses the top of water outlet equipment next time to spout, only need discharge and mix the muddy water that does not reach the settlement temperature in the water pipe way, avoid the lower residual water of temperature to splash on the user body.

s640: and when the temperature of the mixed water reaches the set water temperature, sending a closing signal to the mixed water drain valve and sending an opening signal to the water outlet end water diversion valve so as to discharge water from the water outlet end.

When the control device of the water outlet equipment is electrified and initialized, the water mixing drain valve 21, the top spraying drain valve 32, the top spraying shunt valve 11 and the water outlet end shunt valve 12 are controlled to be in a closed state, so that the water is prevented from being discharged by mistake.

As shown in fig. 7, in the embodiment of the present specification, in step S520 and step S620: before judging whether the water temperature of mixed water reaches the set water temperature, the method comprises the following steps:

s710: acquiring the temperature of cold water in a cold water inlet pipeline and the temperature of hot water in a hot water inlet pipeline;

the cold water temperature of the cold water pipeline can be obtained by receiving an electric signal (which can be a voltage signal, a current signal or an electromagnetic wave signal and the like) which is sent by a cold water temperature sensor and used for representing the cold water temperature; the obtaining of the hot water temperature of the hot water inlet line may be receiving an electrical signal sent by the hot water temperature sensor to characterize the hot water temperature.

S720: and sending a temperature control signal to a water mixing device according to the cold water temperature and the hot water temperature so as to enable the mixed water temperature to reach the set water temperature.

Compared with the existing mode of adjusting the mixing ratio of cold water and hot water by rotating and adjusting the position of the mechanical water mixing valve, the control method provided by the embodiment of the specification can more accurately adjust the flow ratio of the cold water and the hot water, so that the water temperature of mixed water can be more accurately adjusted.

As shown in fig. 8, in order to compensate for the decrease of the user-side water temperature caused by heat loss during the circulation of the mixed water, in an embodiment of the present disclosure, it is preferable that before determining whether the mixed water temperature reaches the set water temperature, the method further includes:

s810: acquiring the environmental temperature of the environment where the water mixing pipeline is located; for example, an electrical signal indicative of the ambient temperature of the environment in which the mixing line is located may be received from an ambient temperature sensor.

S820: and sending a temperature control signal to the water mixing device according to the environment temperature, the cold water temperature and the hot water temperature so as to enable the mixed water temperature to reach the set water temperature.

Specifically, step S820: according to the ambient temperature, the cold water temperature and the hot water temperature, sending a temperature control signal to the water mixing device to enable the mixed water temperature to reach the set water temperature includes:

s910: calculating a compensation temperature according to the environment temperature, wherein the compensation temperature is inversely related to the environment temperature;

the method for calculating the compensated temperature according to the ambient temperature can be seen from the previous description of the control system of the water outlet device, i.e. the method shown in table 1.

S920: determining the actual mixed water temperature of the water mixing device according to the compensation temperature and the set water temperature;

s930: determining a cold-hot water flow ratio required for enabling the mixed water temperature to reach the actual mixed water temperature according to the cold water temperature and the hot water temperature;

s940: and sending a flow regulation and control signal to the water mixing device according to the cold-hot water flow ratio.

In addition to the calculation of the compensation temperature according to the ambient temperature, the compensation temperature can be calculated by referring to the method shown in table 2, i.e., the compensation temperature is calculated according to the set water temperature. Based on the compensation method for the set water temperature, the defect that the outlet water temperature of the user side is actually lower than the set water temperature of the user due to heat loss of mixed water in the process of circulating to the user side can be overcome, so that the outlet water temperature of the water outlet equipment can be kept near the set water temperature more stably, and the use experience of the user can be improved.

In an embodiment of this specification, the method may further include:

and when the opening state of the top spray and/or the water outlet end is received, the state is converted into a working state from a dormant state.

That is, the controller is normally in a sleep state to reduce power consumption; when receiving the wake-up signal sent by the switching detection element, the control unit is switched from the dormant state to the working state. So, can make water outlet apparatus only need carry out under the condition of user at the user, just discharge and not reach the muddy water that sets for the temperature (and when the play water mode is top blowout water, still including the residual water in the residual water pipeline of discharging) to can avoid extravagant water resource.
