The "electrical connection" appearing in other parts of the specification may refer to the explanation, and will not be described in detail.
In the embodiments of the present specification, cold water refers to normal temperature water (e.g., normal temperature tap water), and hot water refers to water (e.g., water having a temperature of 45 ℃, 50 ℃, 60 ℃, etc.) which is supplied from a heat source (i.e., hot water supply device) through the hot water inlet line 12 and has a temperature higher than that of the normal temperature water. The heat source may be, for example, an electric water heater, a gas water heater, a wall-mounted gas boiler, or an air-source water heater.
The water outlet end of the water mixing pipeline 1 is connected with the water outlet pipeline 4 of the handheld shower head. A hand-held shower water distribution valve 7 is arranged on the hand-held shower water outlet pipeline 4; the hand-held shower water distribution valve 7 is used for realizing the connection and disconnection between the water mixing pipeline 1 and the hand-held shower water outlet pipeline 4; the hand-held shower diversion valve 7 is electrically connected with the control unit 16, so that the hand-held shower diversion valve 7 can be opened or closed under the control of the control unit 16. In some embodiments, the handheld shower diversion valve 7 may be a controllable valve such as a solenoid valve.

A mixed water drain valve 5 is arranged on the mixed water discharge pipeline 3; the mixed water drain valve 5 is used for realizing the connection and disconnection between the mixed water pipeline 1 and the mixed water draining pipeline 3; the mixing and draining valve 5 is electrically connected to the control unit 16, so that the mixing and draining valve 5 can be opened or closed under the control of the control unit 16. In some embodiments, the mixing and draining valve 5 may be a controllable valve such as a solenoid valve.
In other embodiments, as shown in connection with fig. 2, the shower device may further comprise a lower water outlet line 2 (typically for a bath). The water outlet end of the water mixing pipeline 1 can also be connected with the lower water outlet pipeline 2. The lower water outlet pipeline 2 is provided with a lower water outlet shunt valve 14; the lower water outlet shunt valve 14 is used for realizing the connection and disconnection between the water mixing pipeline 1 and the lower water outlet pipeline 2; the lower effluent diverter valve 14 is electrically connected to the control unit 16, so that the lower effluent diverter valve 14 can also perform an opening or closing action under the control of the control unit 16. In some embodiments, the lower effluent diverter valve 14 may also be a controllable valve such as a solenoid valve.
In order to simplify the structure, the lower water outlet pipeline 2 can be connected with the water mixing and discharging pipeline 3, so that the lower water outlet of the lower water outlet pipeline 2 can be used as a water mixing and discharging port of the water mixing and discharging pipeline 3. Those skilled in the art will appreciate that this is merely an exemplary illustration, and in other embodiments, the mixing and water discharging pipeline 3 may be provided with a separate mixing and water discharging port according to the requirement; in other embodiments, the mixed water discharging pipeline 3 can be connected with the cold water inlet pipeline 11, so as to recycle the water which does not reach the set water temperature, thereby being beneficial to saving water resources.
The control unit 16 may include a controller or a control board integrated with the controller, or the like. The controller may include, but is not limited to, a single chip, a Microprocessor (MCU), a Digital Signal Processor (DSP), and the like.
The mixed water pipeline 1 is provided with a mixed water temperature sensor 6, and the mixed water temperature sensor 6 is electrically connected with the control unit 16. The mixed water temperature sensor 6 may be configured to collect a mixed water temperature of the mixed water pipeline 1, and output the mixed water temperature to the control unit 16 in the form of an electrical signal. In some embodiments, the control system of the hand-held shower may include a control unit 16, a hand-held shower diversion valve 7, a mixing drain valve 5, and a mixing temperature sensor 6.
When the control unit 16 receives an electrical signal indicative of the temperature of the mixed water, it may compare this electrical signal with a reference signal indicative of the set temperature; when the temperature of the mixed water does not reach the set water temperature, the control unit 16 sends an opening control signal to the mixed water drain valve 5 to control the mixed water drain valve 5 to open so as to drain the mixed water in the mixed water pipeline 1 through the mixed water draining pipeline 3; when the mixed water temperature reaches the set water temperature, an opening control signal is sent to the handheld shower head shunt valve 7 to control the handheld shower head shunt valve 7 to be opened so as to facilitate handheld shower.
It should be noted that in the embodiments of the present specification, the phrase "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; wherein, substantially the same means: the difference value between the mixed water temperature and the set water temperature is not more than a set allowable range (for example, not more than 1 ℃ and the like).
Further, in order to prevent the mixed water reaching the set water temperature from being discharged through the mixed water discharging pipeline 3, when the mixed water temperature reaches the set water temperature, a closing control signal may be sent to the mixed water discharging valve 5. Obviously, it can be seen from the above description that, during the process of performing the power-on initialization by the control system of the handheld shower, the mixed water drain valve 5, the handheld shower diversion valve 7 and the lower water diversion valve 14 are all closed, that is, the mixed water drain valve 5, the handheld shower diversion valve 7 and the lower water diversion valve 14 are all in a closed state when the power-on initialization is completed, so as to avoid mistaken drainage.
In some embodiments, the control system may further include a thermostatic cartridge (not shown) disposed on the mixing line 1. The thermostatic valve core automatically adjusts the mixing proportion of cold water and hot water, so that the temperature of mixed water can be automatically kept at a set temperature; the thermostatic valve core is in a closed state in a normal state, so that the water mixing pipeline 1 is in a closed state; when the temperature of the mixed water reaches the set temperature, the thermostatic valve core is opened, so that the mixed water pipeline 1 is in an open state. In one embodiment, the thermostatic valve core can adopt a shape memory alloy spring as a temperature sensing element, so that the shape memory alloy spring is used as the temperature sensing element and also has the function of pushing the piston to adjust the mixing of cold water and hot water, and the mixed water can also pass through the spring, thereby saving the space and enabling the structure of the thermostatic valve core to become more compact.
With continued reference to fig. 1-3, in some embodiments, the control system of the handheld showerhead may further include a cold water temperature sensor 9 and a hot water temperature sensor 10; the cold water temperature sensor 9 is arranged on a cold water inlet pipeline 11, and the hot water temperature sensor 10 is arranged on a hot water inlet pipeline 12; the cold water temperature sensor 9 and the hot water temperature sensor 10 are respectively electrically connected with the control unit 16. The cold water temperature sensor 9 can be used for collecting the temperature of cold water in the cold water inlet pipeline 11 and outputting the temperature of the cold water to the control unit 16 in the form of an electric signal; the hot water temperature sensor 10 can be used for collecting the temperature of the hot water in the hot water inlet pipeline 12 and outputting the temperature of the hot water to the control unit 16 in the form of an electric signal; in this way, the control unit 16 can output a control signal to the electrically controlled water mixing part 8 according to the cold water temperature and the hot water temperature, so that the mixed water temperature reaches the set water temperature. Wherein, according to cold water temperature and hot water temperature, to automatically controlled water mixing component 8 output make the control signal who mixes water temperature and reach the settlement temperature, can include: determining a cold-hot water flow ratio required for enabling the mixed water temperature to reach a set water temperature according to the cold water temperature and the hot water temperature; and outputting a valve opening control signal to the electric control water mixing part 8 according to the cold-hot water flow ratio. The cold-hot water flow ratio refers to a mixing ratio of the hot water flow and the cold water flow of the electric control water mixing component 8.
Because the hot water flow of the electric control water mixing component 8 is in a direct proportion relation with the water temperature of the mixed water, for the hot water with different temperatures, the direct proportion relation curve of the hot water flow and the water temperature of the mixed water is different; similarly, the cold water flow rate of the electric control water mixing component 8 and the water temperature of the mixed water are in an inverse proportion relation, and for the cold water with different temperatures, the inverse proportion relation curve of the cold water flow rate and the water temperature of the mixed water is also different. Therefore, on the premise that the hot water temperature and the cold water temperature are determined, the hot water flow and the cold water flow are mixed in different proportions, and the mixed water temperatures are different. 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. The mixing proportion can be realized by adjusting the opening degree of a water inlet valve of the electric control water mixing component 8. Therefore, when the cold water temperature and the hot water temperature are determined, the corresponding mapping relation curve can be matched according to the combination of the cold water temperature and the hot water temperature, then the mixing proportion corresponding to the set water temperature can be found from the matched mapping relation curve, the valve opening control signal is generated according to the mixing proportion, and the corresponding valve opening control signal is output to the electric control water mixing component 8, so that the purpose of adjusting the water mixing temperature is achieved.
In some embodiments, the above-mentioned control of generating the valve opening control signal according to the mixing ratio and outputting the corresponding valve opening control signal to the electrically controlled water mixing component 8 may be implemented based on pid (proportion integration differential) regulation. For example, in an exemplary embodiment, taking the electrically controlled water mixing component 8 as an example, when the control system of the handheld shower head is electrically initialized, the control unit 16 controls the water mixing motor to reset to the initial position, so as to control the number of steps of the water mixing motor based on the real-time acquired water mixing temperature PID adjustment, that is, control the valve opening of the water mixing motor by using PID adjustment.
With continued reference to fig. 3, the change of the ambient temperature may affect the temperature of the mixed water, and in order to achieve precise control of the temperature of the mixed water, in another embodiment, the control system of the handheld shower head may further include an ambient temperature sensor 18; the ambient temperature sensor 18 may be used to collect the ambient temperature of the water mixing pipeline 1; correspondingly, the control unit 16 may also output a control signal to the electrically controlled water mixing component 8 according to the cold water temperature, the hot water temperature, and the ambient temperature, so that the mixed water temperature reaches the set water temperature. Wherein, according to cold water temperature, hot water temperature and ambient temperature, export the control signal who makes muddy water temperature reach the settlement temperature to automatically controlled muddy water part, can include: performing temperature compensation on the set water temperature according to the environment temperature to generate a second set water temperature; determining a cold-hot water flow ratio required for enabling the mixed water temperature to reach a second set water temperature according to the cold water temperature and the hot water temperature; and outputting a valve opening control signal to the electric control water mixing component according to the cold-hot water flow ratio.
In some embodiments, the temperature compensating the set water temperature according to the ambient temperature to generate the second set water temperature may include: matching temperature compensation logics corresponding to the ambient temperature from a corresponding relation table between a preset ambient temperature interval and the temperature compensation logics; and generating a second set water temperature according to the temperature compensation logic and the set water temperature. In the above correspondence table, the ith temperature compensation logic can be represented as Ti incrl＝Tin+ΔTiWherein, Ti incrlA second set water temperature, T, corresponding to the ith ambient temperature intervalinTo set the temperature, Δ TiCompensation temperature (Delta T) corresponding to ith environment temperature intervaliNot less than 0). For example, in the correspondence table shown in fig. 4, five temperature compensation logics are provided in one-to-one correspondence with five ambient temperature sections. If the currently detected ambient temperature is 8 ℃, according to the corresponding relationship table shown in fig. 4, since 8 ℃ falls within the ambient temperature interval of 0 < TaWithin the range of less than or equal to 10 ℃, the temperature compensation logic T corresponding to 8 ℃ can be matchedin+Δt2。
In the above correspondence table, the compensation temperature in each temperature compensation logic may be preset according to the following rule: each compensation temperature in the corresponding relation table is inversely related to the corresponding environment temperature interval; i.e. the lower the ambient temperature, the larger the compensation temperature. For example, in an exemplary embodiment, taking the correspondence table shown in fig. 4 as an example, according to such a setting rule, Δ t1 > Δ t2 > Δ t3 > Δ t 4.
Referring to fig. 5 and fig. 6, fig. 5 is a schematic diagram illustrating the change of the outlet water temperature of the hand-held shower head in the prior art; FIG. 6 is a schematic diagram illustrating the change of the outlet water temperature of the handheld shower in an exemplary embodiment of the present disclosure; in fig. 5 and 6, the ordinate represents the mixed water temperature of the handheld shower head. As can be seen by comparing fig. 5 and fig. 6, based on the control system of the handheld shower head of the embodiment of the present specification, the mixed water temperature of the handheld shower head is more stable.
In some embodiments, the control unit 16 may be a low power consumption control unit that is normally (i.e., not used by the user in a shower) in a sleep state to reduce power consumption. Accordingly, referring to fig. 1 to 3, the control system of the hand shower may further include an open/close detection element 17; the opening/closing detection element 17 is provided on or near the hand-held shower opening/closing valve 13. Wherein, handheld gondola water faucet ooff valve 13 is the operation object of the handheld gondola water faucet switch of user control, can manually open handheld gondola water faucet ooff valve 13 when the user needs to take a shower, when the user accomplishes the shower or need not take a shower temporarily, can manually close handheld gondola water faucet ooff valve 13. The on-off detection element 17 can be used for detecting the on-off state of the handheld shower switch valve 13 and determining whether to output a wake-up signal to the control unit 16 according to the detected on-off state; when the opening state of the handheld shower switch valve 13 is detected, a wake-up signal can be output to the control unit 16 to wake up the control unit 16; upon receiving the wake-up signal transmitted from the open/close detection element 17, the control unit 16 switches from the sleep state to the operation state. So, can make shower equipment only need shower (being in the on-state promptly at handheld gondola water faucet ooff valve 13) down at the user, just arrange the muddy water (including the surplus water) that does not reach the settlement temperature to can avoid extravagant water resource.
In some embodiments, the open/close detection element 17 may be a contact type position sensor or a proximity type position sensor or the like. The contact position sensor may be, for example, a travel switch; the proximity position sensor may be, for example, an electromagnetic position sensor, an optoelectronic position sensor, a reed switch, a hall sensor, or the like.
Referring to fig. 1-3, the control system of the handheld showerhead may further include a flow sensor 15; the flow sensor 15 is disposed on the water mixing pipeline 1 and electrically connected to the control unit 16. The flow sensor 15 may be configured to collect a mixed water flow of the mixing pipeline 1 and output the mixed water flow to the control unit 16 in the form of an electrical signal. In some embodiments, the control unit 16 may generate water usage statistics based on the mixed water flow and may display the statistics in real time via the display module to alert the user to conserve water. In other embodiments, the control unit 16 may also perform a shower device malfunction detection based on the amount of mixing water (e.g., to indirectly assist in detecting whether the electrically controlled mixing element 8, the respective diverter valve, and the mixing and draining valve 5 are damaged, etc.). If within a specified time after the user opens the handheld shower head switch valve 13, the mixed water flow detected by the flow sensor 15 is zero (or almost zero), then the control unit 16 can determine that the electric control water mixing component 8, each water dividing valve or the water mixing drain valve 5 may have faults, and the control unit 16 can output a fault alarm (for example, output a fault alarm text message through the display module) so as to remind the user of overhauling.
Referring to fig. 3, the control system of the handheld shower may further include a human-machine interface 19, and the human-machine interface 19 may be electrically connected to the control unit 16 for outputting a control signal for water temperature setting or function control (e.g., on-off control, bath mode selection, etc.) to the control unit 16 according to a user input. In some embodiments, the human machine interface 19 may be a mechanical or touch-control electronic control board mounted on the shower device. In other embodiments, the human machine interface 19 may be a wireless remote control, which may communicate wirelessly with the control unit 16. In other embodiments, the human machine interface 19 may also be a client (APP), which may communicate with the control unit 16 via a communication link. Therefore, the water temperature setting or function control can be remotely (or off-site) carried out by the user through the client. Further, the control unit 16 may memorize and store the set water temperature set by the user, so that it is not necessary to perform the water temperature setting operation every time a shower is taken.
Referring to fig. 3, the control system of the handheld showerhead may further include a power supply module 20; the power module 20 may be used to power the control system of the hand shower. In some embodiments, the power supply module 20 may be a flyback isolation power supply or a lithium battery, which may be beneficial to simplifying a circuit structure of a control system of the handheld shower head and reducing implementation cost.
