Description

Technical Field

[0001] This utility model relates to the technical field of automated temperature control systems for faucets, and more particularly to an intelligent water temperature adjustment module, which is especially suitable for upgrading and transforming intelligent shower systems, countertops, and existing shower systems. Background Technology

[0002] Therefore, the applicant has applied for and filed a Chinese utility model patent with patent number CN202420856672.1 (publication number CN222229538U), disclosing a thermostat for controlling water temperature. The thermostat includes a valve seat having a cold water inlet channel, a hot water inlet channel, a first valve core mounting cavity, a second valve core mounting cavity, a cold water outlet channel, a hot water outlet channel, a mixing chamber, a third valve core mounting cavity, and a mixed water outlet channel. The mixing chamber is connected to the mixed water outlet channel. A first flow regulating valve core is installed in the first valve core mounting cavity. The cold water inlet channel is connected to the first inlet end of the first flow regulating valve core, and the first outlet end of the first flow regulating valve core is connected to... The cold water outlet channel is connected, and the first moving valve plate of the first flow regulating valve core is driven to rotate by the first motor to regulate the cold water flow. The second flow regulating valve core is installed in the second valve core mounting cavity. The hot water inlet channel is connected to the second inlet end of the second flow regulating valve core, and the second outlet end of the second flow regulating valve core is connected to the hot water outlet channel. The second moving valve plate of the second flow regulating valve core is driven to rotate by the second motor to regulate the hot water flow. The balancing valve core is installed in the third valve core mounting cavity. The cold water outlet channel is connected to the cold water inlet of the balancing valve core, and the hot water outlet channel is connected to the hot water inlet of the balancing valve core. Both the cold water outlet and the hot water outlet of the balancing valve core are connected to the mixing chamber.

[0003] The aforementioned controller lacks a suitable location for installing the control circuit board, necessitating its relocation to another location. The two flow control valves, which regulate both the outflow water volume and the mixing ratio, complicate the control process. The balancing valve, located at the outlet, causes fluctuations in water temperature, requiring simultaneous responses from the first motor, second motor, and balancing valve. This places high demands on the program control, resulting in a less than ideal user experience in actual use.

[0004] Therefore, the existing automatic temperature control modules for faucets still need further improvement. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a smart water temperature regulation module with a reasonable structure and convenient circuit board installation, which is convenient to be selected and combined with other regulation modules in view of the current situation of the prior art.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an intelligent water temperature regulation module, including a valve seat, the valve seat having a cold water inlet channel, a hot water inlet channel, a first valve core mounting cavity, a second valve core mounting cavity, a mixing cavity, and a mixed water outlet channel; characterized in that: a first valve core is installed in the first valve core mounting cavity, the cold water inlet channel is connected to the inlet end of the first valve core, the outlet end of the first valve core is connected to the mixing cavity, and the movable valve plate of the first valve core is driven to rotate by a first motor to regulate the flow rate of cold water flowing into the mixing cavity per unit time; a second valve core is installed in the second valve core mounting cavity, the hot water inlet channel is connected to the inlet end of the second valve core, the outlet end of the second valve core is connected to the mixing cavity, and the movable valve plate of the second valve core is driven to rotate by a second motor to regulate the flow rate of hot water flowing into the mixing cavity per unit time; the mixing ratio of cold water and hot water flowing into the mixing cavity is adjusted through the combined action of the first valve core and the second valve core, and the mixing cavity is connected to the mixed water outlet channel; a receiving cavity for accommodating the control circuit board is provided on the outer surface of the valve seat.

[0007] To facilitate fixing the circuit board inside the accommodating cavity, as an improvement, the accommodating cavity is provided with a protruding mounting post, which has a threaded hole. The circuit board is fixed to the mounting post by screws.

[0008] To further improve the automatic adjustment of the outlet water temperature quickly and accurately, a mixing water temperature sensor is also included. The sensor's sensing head extends into the mixed water outlet channel. The water temperature signal measured by the mixing water temperature sensor is compared with the set temperature. The information control module sends a final signal to the two motor control modules, allowing the moving valve plates of the two valve cores to quickly rotate to the correct angle. Due to its very fast response speed, the problem of fluctuating temperatures in the mixed water outlet is significantly improved.

[0009] Further improvements include cold water temperature sensors and hot water temperature sensors. The sensing head of the cold water temperature sensor extends into the third cold water inlet channel, and the sensing head of the hot water temperature sensor extends into the third hot water inlet channel. The two temperature sensors measure the temperatures of the cold and hot water respectively, and send the detected water temperature data to the information control module. The information control module, based on a model (which clearly defines the flow rates of hot and cold water to be mixed, thus obtaining the corresponding flow rate and temperature of the mixed water), roughly determines the required rotation angle range for the moving valve plates of the two valve cores used for temperature adjustment, so that the mixed water reaches the set temperature and flow rate. At this point, the moving valve plates of the two valve cores will rotate to an angle in advance, an angle that is already close to the final required rotation angle for the set temperature.

[0010] As an improvement, a water flow generator is also installed inside the mixing chamber. A water flow generator is a structure that uses water flow to generate electricity; this is existing technology. In this solution, the water flow generator is placed inside the mixing chamber, and the water flowing in from both sides jointly drives the impeller of the water flow generator to rotate, resulting in higher power generation efficiency. The electrical energy generated by the water flow generator can supply the display screen, or it can supply the battery or other electrical components.

[0011] To ensure a rational layout of the flow channels, as a preferred arrangement, the first and second valve core mounting cavities are coaxially connected, with plugs at both ends of the valve seat for sealing, facilitating the molding of the two valve core mounting cavities. The openings of both cavities face upwards, allowing the valve core to be inserted into them from top to bottom, simplifying assembly. Furthermore, the first valve core mounting cavity and the cold water inlet channel are longitudinally coaxial, as are the second valve core mounting cavity and the hot water inlet channel, and the mixing chamber and the mixed water outlet channel are longitudinally coaxial. This vertically connected design facilitates product molding and makes core extraction during manufacturing easier.

[0012] To facilitate connection of this water temperature regulation module with other modules (such as pressure balancing module and flow regulation module), the valve seat has three downwardly extending connecting posts, and the cold water inlet channel, hot water inlet channel and mixed water outlet channel respectively pass through the connecting posts.

[0013] To achieve automatic water distribution, an improvement includes a diversion module. This module includes a diversion valve seat with a mixed water inflow channel, a diversion valve core mounting cavity, and multiple outlet channels. A diversion valve core, controlled by a third motor, is installed in the diversion valve core mounting cavity. The mixed water outflow channel is connected to the mixed water inflow channel, which is also connected to the inlet end of the diversion valve core. The multiple outlet ends of the diversion valve core are correspondingly connected to each of the outlet channels. The movable valve plate of the diversion valve core is driven to rotate by the third motor, allowing water to selectively flow through a specific outlet end and outlet channel. This water distribution function is particularly suitable for shower systems.

[0014] To ensure a rational layout of the flow channels, as another preferred arrangement, the first and second valve core mounting cavities are coaxially connected, facilitating the molding of two valve core mounting cavities. The valve core can be laterally inserted into these cavities. The cold water inlet channel and hot water inlet channel are vertically oriented downwards, while the mixed water outlet channel is vertically oriented upwards, located between the cold water inlet channel and the hot water inlet channel. This vertically connected arrangement facilitates product molding and makes core extraction during manufacturing easier.

[0015] To facilitate fixing the entire adjustment module to the mounting wall, the valve seat is provided with mounting ears, and the mounting ears are provided with mounting holes.

[0016] Compared with the prior art, the advantages of this utility model are: 1. This water temperature adjustment method uses a dual-valve core structure to adjust the water temperature. Because there are two motors to adjust the ratio of hot and cold water to the corresponding valve cores, the overall control of water temperature adjustment is simpler, the program requirements are lower, and the adjustment is more precise. Water temperature adjustment can be completed by adjusting the flow rate of cold water and hot water flowing into the mixing chamber accordingly. In addition, the valve plate group of a single valve core is also simpler, and the most traditional adjustable flow valve plate group can be used.

[0017] 2. This module is only used to adjust the water temperature. It is convenient to select and use with other modules (such as pressure balance module and flow regulation module), making it more versatile. Each module has an independent function, which can effectively reduce the difficulty of control and manufacturing, and greatly improve the control accuracy of the outlet water temperature.

[0018] 3. The outer surface of the valve seat is provided with a cavity for accommodating the control circuit board, providing a suitable installation position for the circuit board, eliminating the need for separate control components and achieving higher integration. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-5 The image shown is the first embodiment of this utility model.

[0022] A smart water temperature regulation module includes a valve seat 1, which has a cold water inlet channel 1a, a hot water inlet channel 1b, a first valve core mounting cavity 1e, a second valve core mounting cavity 1f, a mixing cavity 1c, and a mixed water outlet channel 1d; the valve seat 1 is provided with a mounting ear 13, and the mounting ear 13 is provided with a mounting hole 131.

[0023] A first valve core 2a is installed in the first valve core mounting cavity 1e. The cold water inlet channel 1a is connected to the water inlet end of the first valve core 2a, and the water outlet end of the first valve core 2a is connected to the mixing chamber 1c. The moving valve plate of the first valve core 2a is driven to rotate by the first motor 3a to adjust the flow rate of cold water flowing into the mixing chamber 1c per unit time. The second valve core 2b is installed in the second valve core mounting cavity 1f. The hot water inlet channel 1b is connected to the water inlet end of the second valve core 2b, and the water outlet end of the second valve core 2b is connected to the mixing chamber 1c. The moving valve plate of the second valve core 2b is driven to rotate by the second motor 3b to adjust the flow rate of hot water flowing into the mixing chamber 1c per unit time. The first valve core 2a and the second valve core 2b are actually the same valve plates as the flow regulating valve core, and play the role of regulating water volume. Through the combined action of the first valve core 2a and the second valve core 2b, the mixing ratio of cold water and hot water flowing into the mixing chamber 1c is adjusted. The mixing chamber 1c is connected to the mixed water outflow channel 1d. The outer surface of the valve seat 1 is provided with a receiving cavity 11 for accommodating the control circuit board 8. The receiving cavity 11 is provided with a protruding mounting post 111, and the mounting post 111 is provided with a threaded hole 112. The circuit board 8 is fixed to the mounting post 111 by screws.

[0024] It also includes a mixing water temperature sensor 6c, a cold water temperature sensor 6a, and a hot water temperature sensor 6b. The sensing head of the mixing water temperature sensor 6c extends into the mixing water outlet channel 1d. The sensing head of the cold water temperature sensor 6a extends into the cold water inlet channel 1a, and the sensing head of the hot water temperature sensor 6b extends into the hot water inlet channel 1b. The mixing water temperature sensor 6c, cold water temperature sensor 6a, and hot water temperature sensor 6b are electrically connected to the circuit board 8, which is also electrically connected to the information control module. The circuit board 8 is also equipped with touch buttons for setting the outlet water temperature and starting or stopping the circuit.

[0025] A water flow generator 4 is also installed inside the mixing chamber 1c. The water flow generator 4 is a structure that uses water flow to generate electricity. It is an existing technology. The water flowing in from both sides jointly drives the impeller of the water flow generator 4 to rotate, resulting in higher power generation efficiency. The electrical energy generated by the water flow generator 4 can supply the display screen, or it can supply the battery or other electrical components.

[0026] The first valve core mounting cavity 1e and the second valve core mounting cavity 1f are coaxially connected. Both ends of the valve seat 1 are sealed with plugs 7. The openings of the first valve core mounting cavity 1e and the second valve core mounting cavity 1f face upwards. The first valve core mounting cavity 1e and the cold water inlet channel 1a are longitudinally coaxially connected, the second valve core mounting cavity 1f and the hot water inlet channel 1b are longitudinally coaxially connected, and the mixing chamber 1c and the mixed water outlet channel 1d are longitudinally coaxially connected. The valve seat 1 has three downwardly extending connecting posts 12, through which the cold water inlet channel 1a, the hot water inlet channel 1b, and the mixed water outlet channel 1d respectively pass.

[0027] Of course, the directions of entry for cold and hot water can be interchanged. That is, hot water can also enter through cold water channel 1a, and cold water can also enter through hot water channel 1b.

[0028] 1. This water temperature adjustment method uses a dual-valve core structure to adjust the water temperature. The moving valve plate of the first valve core 2a is driven to rotate by the first motor 3a to adjust the flow rate of cold water flowing into the mixing chamber 1c per unit time; the moving valve plate of the second valve core 2b is driven to rotate by the second motor 3b to adjust the flow rate of hot water flowing into the mixing chamber 1c per unit time. The ratio of cold and hot water entering the mixing chamber 1c is adjusted according to the set water temperature. The overall control of water temperature adjustment is simpler, the program requirements are lower, and the adjustment is more precise. Water temperature adjustment can be completed by adjusting the flow rates of cold and hot water flowing into the mixing chamber 1c accordingly. Moreover, the valve plate group of a single valve core is also simpler, and the most traditional adjustable flow valve plate group can be used.

[0029] 2. This module is only used to adjust the water temperature. It is convenient to select and use with other modules (such as pressure balance module and flow regulation module), making it more versatile. Each module has an independent function, which can effectively reduce the difficulty of control and manufacturing, and greatly improve the control accuracy of the outlet water temperature.

[0030] 3. The outer surface of the valve seat 1 is provided with a receiving cavity 11 for accommodating the control circuit board 8, providing a suitable installation position for the circuit board 8, eliminating the need for separate control components and achieving higher integration.

[0031] like Figure 6 The following is a second embodiment of the present invention.

[0032] The difference between this embodiment and the second embodiment is that: the first valve core mounting cavity 1e and the second valve core mounting cavity 1f are coaxially connected, the opening ends of the first valve core mounting cavity 1e and the second valve core mounting cavity 1f face upwards, the cold water inlet channel 1a and the hot water inlet channel 1b are arranged vertically downwards, the mixed water outlet channel 1d is arranged vertically upwards, and the mixed water outlet channel 1d is located between the cold water inlet channel 1a and the hot water inlet channel 1b.

[0033] It also includes a diversion module 5, which includes a diversion valve seat 51. The diversion valve seat 51 has a mixed water inflow channel 5a, a diversion valve core mounting cavity 5b, and multiple outlet channels 5c. A diversion valve core 52 controlled by a third motor 3c is installed in the diversion valve core mounting cavity 5b. The mixed water outflow channel 3d is connected to the mixed water inflow channel 5a. The mixed water inflow channel 5a is connected to the inlet end of the diversion valve core 52. The multiple outlet ends of the diversion valve core 52 are connected to each of the outlet channels 5c. The moving valve plate of the diversion valve core 52 is driven to rotate by the third motor 3c, so that the water flows out through a corresponding outlet end and a corresponding outlet channel 5c. The valve plate assembly of the diversion valve core 52 is similar to that of conventional diversion valve cores on the market.

[0034] The diversion module 5 can also use a water pipe to connect the mixed water outflow channel 3d with the mixed water inflow channel 5a.
