Description

Technical Field

[0001] This utility model relates to the technical field of automated temperature control systems for faucets, and more particularly to a single-motor intelligent water circuit controller for water inlet. Background Technology

[0002] Traditional shower products mostly use mechanical switches to control the inlet and outlet water volume, water temperature, and selection of water outlets. This operation method is inconvenient and the adjustment is not accurate enough. If the user applies too much force to the mechanical switch, it will cause excessive changes in flow or temperature, thus failing to achieve the purpose of precise adjustment. Therefore, electronic intelligent water circuit controllers have emerged on the market. They use a control box to adjust the water temperature and flow, and then connect the various outlets of the control box to multiple water outlets, so that the shower product can make the water flow from the outlets according to the user's needs.

[0003] Currently, existing intelligent water circuit controllers, such as the Chinese utility model "Thermostat for Controlling Water Temperature" with patent application number CN202420856672.1 (authorization announcement number CN222229538U), have a valve seat with a first flow regulating valve core and a second flow regulating valve core respectively installed on the cold water inlet channel and the hot water inlet channel. The first and second flow regulating valve cores are controlled by a first motor and a second motor respectively. The first and second flow regulating valve cores are used to regulate the flow rates of cold water and hot water respectively to achieve water temperature and flow control. The valve seat also has a balancing valve core. By moving the piston in the balancing valve core, the flow rates of cold water and hot water are regulated to ensure that the two can be mixed according to a preset ratio, avoiding the problem of sudden changes in water temperature.

[0004] The two flow control valves in the aforementioned controller require separate motors for control. This not only complicates the controller's structure but also risks preventing simultaneous opening and closing of the two valves. The potential time lag in the motors' responses could lead to overheating or undercooling of the outlet water, negatively impacting the user experience. Furthermore, existing controllers often place the balancing valve after the temperature control valve. However, water pressure instability typically occurs at the inlet, requiring both motors of the flow control valves to react rapidly and simultaneously, placing high demands on program control. Additionally, the integrated temperature control, balancing, water distribution, and emergency switch modules on a single valve seat complicate valve seat manufacturing. If customers require only a few modules, the valve seat must be redesigned and remanufactured, preventing modular separation. Therefore, further improvements to the intelligent water circuit controller are necessary. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a single-motor intelligent water circuit controller with a reasonable structure that can be switched on and off simultaneously and has a better effect on balancing hot and cold water pressure, in light of the above-mentioned existing technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: This single-motor intelligent water circuit controller is characterized by: including a valve seat, which has a cold water inlet channel, a hot water inlet channel, a first mounting cavity, a second mounting cavity, and a mixing cavity; a flow regulating valve core installed in the first mounting cavity, which is driven by a first motor to simultaneously regulate the flow rates of cold water and hot water; a temperature regulating valve core installed in the mixing cavity, which is driven by a second motor to regulate the mixing ratio of cold water and hot water; and a balancing valve core installed in the second mounting cavity, wherein the cold water inlet end of the balancing valve core is directly or indirectly connected to the cold water inlet channel, the hot water inlet end of the balancing valve core is directly or indirectly connected to the hot water inlet channel, and the cold water outlet end and the hot water outlet end of the balancing valve core are directly or indirectly connected to the two inlets of the temperature regulating valve core, respectively.

[0007] Furthermore, the bottom of the flow regulating valve core has four connection holes, which are respectively used for cold water inlet, cold water outlet, hot water inlet, and hot water outlet. The flow regulating valve core includes a fixed valve plate and a movable valve plate. The fixed valve plate has water passage holes corresponding to the four connection holes, and the movable valve plate has two adjusting grooves. The first motor drives the movable valve plate to rotate around its own axis to simultaneously adjust the overlapping area of ​​the two adjusting grooves with the cold water inlet connection holes and the hot water inlet connection holes. This flow regulating valve core structure has the function of simultaneously opening and closing and simultaneously regulating the flow of cold water and hot water. When the adjusting grooves are misaligned with the cold water inlet connection holes and the hot water inlet connection holes, the flow regulating valve core is closed. When the adjusting grooves overlap with the cold water inlet connection holes and the hot water inlet connection holes, the flow regulating valve core is open. The larger the overlapping area of ​​the adjusting grooves with the cold water inlet connection holes and the hot water inlet connection holes, the greater the flow of cold water and hot water caused by the flow regulating valve core.

[0008] Furthermore, the valve seat also has a cold water outlet channel and a hot water outlet channel. The two connection holes of the flow-regulating valve core for cold water inlet and hot water inlet are respectively connected to the cold water inlet channel and the hot water inlet channel. The two connection holes of the flow-regulating valve core for cold water outlet and hot water outlet are respectively connected to the cold water outlet channel and the hot water outlet channel. The cold water inlet end of the balancing valve core is connected to the cold water outlet channel, and the hot water inlet end of the balancing valve core is connected to the hot water outlet channel. The cold water outlet end and the hot water outlet end of the balancing valve core are directly connected to the two inlets of the temperature-regulating valve core. The cold water and hot water flowing into the valve seat are first controlled by the flow-regulating valve core, thereby adjusting the flow rate of cold water and hot water to control the flow rate of mixed water flowing out of the valve seat. Furthermore, the balancing valve core is positioned between the flow-regulating valve core and the temperature-regulating valve core, stabilizing the water pressure of the cold water and hot water flowing into the temperature-regulating valve core, and simplifying the control programs of the first and second motors. In addition, placing the flow-regulating valve core before the balancing valve core prevents backflow of water within the balancing valve core.

[0009] Furthermore, the inlet cold water end and the inlet hot water end of the balancing valve core are directly connected to the inlet cold water channel and the inlet hot water channel, respectively. The outlet cold water end and the outlet hot water end of the balancing valve core are connected to the two connection holes of the flow regulating valve core for inlet cold water and inlet hot water, respectively. The valve seat has an outlet cold water channel and an outlet hot water channel. The two connection holes of the flow regulating valve core for outlet cold water and outlet hot water are connected to the outlet cold water channel and outlet hot water channel, respectively. The outlet cold water channel and outlet hot water channel are also connected to the two inlets of the temperature regulating valve core, respectively. This balancing valve core is installed before the flow regulating valve core in the intelligent water circuit controller, so that the water pressure of the cold and hot water flowing into the flow regulating valve core and the temperature regulating valve core is constant, and the control program of the first motor and the second motor is simpler.

[0010] Furthermore, both the cold water inlet channel and the hot water inlet channel are equipped with one-way valves. The one-way valves can prevent backflow of the balance valve core from affecting the water intake effect of the cold water inlet channel and the hot water inlet channel.

[0011] Furthermore, it also includes a water distribution valve core. The valve seat has a third mounting cavity, a mixing channel, and multiple mixing outlet channels. The water distribution valve core is installed in the third mounting cavity. The outlet of the temperature regulating valve core is connected to the mixing channel, the inlet of the water distribution valve core is connected to the mixing channel, and each outlet of the water distribution valve core is connected to a corresponding mixing outlet channel. The mixing water, mixed in a certain proportion by the temperature regulating valve core, flows into the water distribution valve core through the mixing channel. The water distribution valve core is controlled to select the terminal from which the mixing water flows out.

[0012] Furthermore, the valve seat includes a first valve housing and a second valve housing that can be sealed together. The first valve housing has a hot water inlet channel, a first mounting cavity, a second mounting cavity, and a mixing cavity. The second valve housing has a third mounting cavity. Both the first and second valve housings also have multiple flow channels. When the first and second valve housings are sealed together, the multiple flow channels can form a cold water inlet channel, a mixing channel, and a mixing outlet channel. The valve seat is divided into two valve housings, which can be equipped with several modules, including a temperature control module, a balancing module, a flow rate control module, a water distribution module, and an emergency switch module. This allows customers to easily assemble the valve housings based on the required modules if only a few modules are needed, without redesigning the valve seat. This modular design simplifies the manufacturing of the intelligent water circuit controller.

[0013] Furthermore, the valve seat also has a fourth mounting cavity, which communicates with the mixing water channel. An emergency switch valve core is installed in the fourth mounting cavity. This emergency switch valve core is used to manually control whether the mixing water in the mixing water channel can flow. Equipping the intelligent water circuit controller with an emergency switch valve core allows for manual shut-off of the main water supply in the event of motor failure, making it more user-friendly.

[0014] Furthermore, the mixing channel is divided into a first mixing channel and a second mixing channel. One end of the first mixing channel is connected to the outlet of the temperature regulating valve core, and the other end is connected to the inlet mixing end of the emergency switch valve core. One end of the second mixing channel is connected to the outlet mixing end of the emergency switch valve core, and the other end is connected to the inlet mixing port of the water distribution valve core. The emergency switch valve core includes a valve stem exposed on the valve seat. Manually swinging the valve stem can control whether the inlet mixing end and the outlet mixing end are connected. The inlet mixing end and the outlet mixing end of the emergency switch valve core are connected to the first mixing channel and the second mixing channel, respectively. Manually swinging the valve stem connects or disconnects the cavity inside the emergency switch valve core, thereby controlling whether the inlet mixing end and the outlet mixing end are connected, and thus controlling whether the intelligent water circuit controller can dispense water.

[0015] Furthermore, at least one temperature sensor for detecting the temperature of the mixed water is provided in the mixing channel. The temperature sensor can detect the temperature of the mixed water, and the information module of the intelligent water circuit controller compares the detected temperature with the temperature required by the user and feeds this information back to the second motor control module, so that the temperature regulating valve core can mix water at the temperature required by the user.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] (1) The balance valve core of the intelligent water circuit controller is set before the temperature regulating valve core, that is, the balance valve core is set at the water inlet end of the water circuit. The balance valve core can control the cold water and hot water pressure entering the intelligent water circuit controller to be constant. Furthermore, since the balance valve core is set before the temperature regulating valve core, the requirement for the second motor used to control the temperature regulating valve core to respond to water pressure stability is reduced. Therefore, the intelligent water circuit controller can better control the temperature of the mixed water, so that the water flow from the intelligent water circuit controller can not only meet the user's water temperature requirements, but also ensure a constant water temperature.

[0018] (2) The temperature control valve core of the intelligent water circuit controller is a valve that opens and closes at the same time, that is, the temperature control valve core can simultaneously adjust the cold water and hot water switches and the flow rate, which not only makes the structure of the intelligent water circuit controller simpler, but also improves the performance of the intelligent water circuit controller.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1-14 The figure shown is Embodiment 1 of this utility model.

[0035] The single-motor intelligent water circuit controller for water inlet in this embodiment includes a valve seat 1, a flow regulating valve core 2, a temperature regulating valve core 4, a balancing valve core 5, a water distribution valve core 6, an emergency switch valve core 7, and a temperature sensor 8.

[0036] In this embodiment, the valve seat 1 has a cold water inlet channel 1a, a hot water inlet channel 1b, a first mounting cavity 1c, a second mounting cavity 1d, a mixing cavity 1e, a cold water outlet channel 1f, a hot water outlet channel 1g, a third mounting cavity 1h, a mixing channel 1i, a fourth mounting cavity 1k, and multiple mixing outlet channels 1j. Furthermore, the valve seat 1 in this embodiment includes a first valve shell 11 and a second valve shell 12 that can be sealed together. The first valve shell 11 has a hot water inlet channel 1b, a first mounting cavity 1c, a second mounting cavity 1d, and a mixing cavity 1e. The second valve shell 12 has a third mounting cavity 1h. Both the first and second valve shells also have multiple channels. When the first and second valve shells are in a sealed connection, the multiple channels can form the cold water inlet channel 1a, the mixing channel 1i, and the mixing outlet channel 1j. The first and second valve shells 11 can be tightly connected together by screws.

[0037] In this embodiment, the flow control valve core 2 is installed in the first mounting cavity 1c. The flow control valve core 2 is driven by the first motor 3a to simultaneously regulate the flow rates of cold water and hot water. The bottom of the flow control valve core 2 has four connection holes 21, which are respectively used for cold water inlet, cold water outlet, hot water inlet, and hot water outlet. The flow control valve core 2 includes a fixed valve plate 22 and a movable valve plate 23. The fixed valve plate 22 has water passage holes 221 corresponding to the four connection holes 21. The movable valve plate 23 has two adjusting grooves 231. The first motor 3a drives the movable valve plate 23 to rotate around its own axis to simultaneously adjust the overlapping area of ​​the two adjusting grooves 231 with the cold water inlet connection holes 21 and the hot water inlet connection holes 21. Furthermore, the two connection holes 21 for cold water inlet and hot water outlet of the flow control valve core 2 in this embodiment are respectively connected to the cold water inlet channel 1a and the hot water inlet channel 1b, and the two connection holes 21 for cold water outlet and hot water outlet of the flow control valve core 2 are respectively connected to the cold water outlet channel 1f and the hot water outlet channel 1g. The flow control valve core 2 simultaneously regulates the flow rates of both cold and hot water, and the water flow rate can be adjusted at the inlet end of the valve seat 1.

[0038] In this embodiment, the temperature regulating valve core 4 is installed in the mixing chamber 1e. The temperature regulating valve core 4 is driven by the second motor 3b to adjust the mixing ratio of cold water and hot water. In this embodiment, the balancing valve core 5 is installed in the second mounting chamber 1d. The cold water inlet 51 of the balancing valve core 5 is connected to the cold water outlet channel 1f, and the hot water inlet 52 of the balancing valve core 5 is connected to the hot water outlet channel 1g. The cold water outlet 53 and the hot water outlet 54 of the balancing valve core 5 are directly connected to the two inlets 41 of the temperature regulating valve core 4, respectively. The outlet 42 of the temperature regulating valve core 4 is connected to the mixing channel 1i. The balancing valve core 5 is positioned between the flow regulating valve core 2 and the temperature regulating valve core 4 to stabilize the water pressure of the cold and hot water flowing into the temperature regulating valve core 4. This simplifies the control program of the first motor 3a and the second motor 3b. Furthermore, positioning the flow regulating valve core 2 before the balancing valve core 5 prevents backflow of water within the balancing valve core 5.

[0039] In this embodiment, the water distribution valve core 6 is installed in the third mounting cavity 1h. The inlet 61 of the water distribution valve core 6 is connected to the mixing channel 1i, and the three outlets 62 of the water distribution valve core 6 are respectively connected to the corresponding mixing outflow channels 1j. That is, the mixed water mixed by the temperature regulating valve core 4 according to a certain ratio flows into the water distribution valve core 6 through the mixing channel 1i. The terminal of the mixed water outflow is selected by controlling the water distribution valve core 6. In this embodiment, the emergency switch valve core 7 is installed in the fourth mounting cavity 1k, which is connected to the mixing channel 1i. The emergency switch valve core 7 is used to manually control whether the mixed water in the mixing channel 1i can flow. In this embodiment, the mixing channel 1i is divided into a first mixing channel 1i1 and a second mixing channel 1i2. One end of the first mixing channel 1i1 is connected to the outlet 42 of the temperature regulating valve core 4, and the other end is connected to the inlet mixing end 71 of the emergency switch valve core 7. One end of the second mixing channel 1i2 is connected to the outlet mixing end 72 of the emergency switch valve core 7, and the other end is connected to the inlet mixing end 61 of the water distribution valve core 6. The emergency switch valve core 7 includes a valve stem 73 exposed on the valve seat 1. Manually swinging the valve stem 73 can control whether the inlet mixing end 71 and the outlet mixing end 72 are connected. In addition, the mixing channel 1i in this embodiment is equipped with a temperature sensor 8 for detecting the temperature of the mixed water. In the intelligent water circuit controller of this embodiment, the information module compares the temperature detected by the temperature sensor 8 with the temperature required by the user and feeds the information back to the control module of the second motor 3b, so that the temperature regulating valve core 4 can mix water that meets the user's required temperature.

[0040] The workflow of this embodiment is as follows:

[0041] A. Cold water flows into the flow regulating valve core 2 through the cold water inlet channel 1a, and hot water flows into the flow regulating valve core 2 through the hot water inlet channel 1b. The first motor 3a drives and controls the moving valve plate 23 of the flow regulating valve core 2 to rotate, adjusting the overlapping area of ​​the regulating groove 231 with the cold water inlet connection hole 21 and the hot water inlet connection hole 21, thereby simultaneously regulating the flow rates of cold water and hot water.

[0042] B. The cold water and hot water flowing out of the flow regulating valve core 2 flow out through the cold water outlet channel 1f and the hot water outlet channel 1g respectively and then flow into the balance valve core 5. The balance valve core 5 keeps the water pressure of the cold water and hot water constant by means of the movement of the balance component. The cold water and hot water flowing out of the balance valve core 5 flow into the temperature regulating valve core 4 through the two channels.

[0043] C. The second motor 3b drives the temperature regulating valve core 4 to mix cold water and hot water in a certain proportion to form mixed water at the required temperature. The mixed water flowing out of the temperature regulating valve core 4 flows into the emergency switch valve core 7 through the first mixed water flow channel 1i1. The inlet mixed water end 71 and the outlet mixed water end 72 of the emergency switch valve core 7 are connected. The mixed water flowing out of the emergency switch valve core 7 flows into the water distribution valve core 6 through the second mixed water flow channel 1i2. The water distribution valve core 6 selects one or two mixed water outflow channels 1j to make the mixed water flow out of the valve seat 1.

Furthermore, in this embodiment, both the cold water inlet channel 1a and the hot water inlet channel 1b are equipped with one-way valves.
