Description

Constant temperature shower controller, shower control method and constant temperature shower device Technical Field

[0001] The present invention relates to the technical field of constant temperature shower devices, and in particular to a constant temperature shower controller, a shower control method and a constant temperature shower device. Background Art

[0002] At present, constant temperature shower devices on the market generally have several common problems, such as hot and cold water jumping and poor user experience under low temperature conditions.

[0003] Regarding the issue of water leakage, when using public pipe network water supply systems, the phenomenon of cold and hot water mixing when the product is not in use seriously disrupts the normal operation of the water pipe network. The existing method of installing a one-way check valve as a switch device to prevent water leakage occurs. However, the one-way check valve itself has defects, which can easily increase water resistance and resistance, resulting in fluctuating water temperature, which may lead to many technical risks.

[0004] Especially in terms of user experience, in the hot summer, the cold water supply temperature is higher, and the constant temperature shower device can quickly output constant temperature water, so you don't have to wait too long to use the desired constant temperature water. In the cold winter, the cold water supply temperature is lower, and the constant temperature shower device has poor controllability and adjustability of the input flow, which affects the output temperature of the mixed water, resulting in a slower constant temperature water output speed and a longer wait time before the constant temperature water can be used. The long wait seriously affects the product experience, so a feasible solution is urgently needed.

[0005] Summary of the Invention

[0006] In view of this, an object of the present invention is to provide a constant temperature shower controller to solve the above problems.

[0007] The present invention adopts the following scheme:

[0008] The present application provides a constant temperature shower controller, comprising a main body provided with a constant temperature valve core, wherein the main body is provided with a cold water channel, a hot water channel and a water outlet channel; the cold water channel and the hot water channel are mixed in a mixing chamber of the constant temperature valve core and then water is discharged from the water outlet channel; the cold water channel is provided with a regulating mechanism for regulating the amount of cold water entering the mixing chamber to regulate the amount of cold water input into the mixing chamber from the cold water channel, so that after the water outlet channel is opened, the cold water remaining in the hot water channel is preferentially discharged, thereby allowing the mixing chamber to quickly provide constant temperature water to the water outlet channel at a preset temperature.

[0009] Furthermore, the regulating mechanism is a flow regulating valve with an opening and closing function, and the thermostatic valve core is arranged on a path close to the hot water channel and is located at the connection between the hot water channel and the cold water channel and the water outlet channel.

[0010] Furthermore, after the shower controller drains the residual water therein, the regulating mechanism is adapted to be opened to allow the cold water in the cold water channel to begin to flow into the mixing chamber so that the mixed water reaches a preset temperature.

[0011] Furthermore, the regulating mechanism has a closed state and an open state with multiple regulating gears, and the amount of cold water input into the mixing chamber can be flexibly controlled by adjusting the opening sizes of different gears.

[0012] Furthermore, one end side of the main body is connected to the cold water channel to access the cold water inlet, and the other end side of the main body is connected to the hot water channel to access the hot water inlet; and the water outlet channel is divided into multiple water passages along the water outlet direction, and the main body is provided with a water outlet joint connected to the water passage, and a valve core component for independently controlling the water outlet of each water passage to the corresponding water outlet joint.

[0013] Furthermore, an anti-freeze cracking mechanism is correspondingly provided in the water outlet channel, and the anti-freeze cracking mechanism is configured to adaptively absorb the water pressure in the water outlet channel.

[0014] Furthermore, filtering mechanisms are provided on the paths of the cold water channel and the hot water channel.

[0015] The present invention also provides a shower control method, using any one of the above-mentioned constant temperature shower controllers, wherein the constant temperature shower controller presets the water outlet temperature, and in an initial state, after the regulating mechanism is closed, the cold water channel is disconnected to prevent cold water from entering the mixing chamber. When entering the use state, the steps are as follows:

[0016] The first step is to open the water outlet channel to discharge the cold water in the hot water channel that is lower than the set temperature, so that the outlet water temperature in the mixing chamber quickly reaches the set temperature;

[0017] In the second step, the amount of cold water in the cold water channel entering the mixing chamber is controlled by the regulating mechanism so that the mixed water in the mixing chamber reaches a preset temperature.

[0018] Furthermore, after the above second step is completed, the following two steps are also included:

[0019] The water outlet channel and the regulating mechanism are closed to enter the initial state.

[0020] The present invention further provides a constant temperature shower device, comprising any one of the above-mentioned constant temperature shower controllers.

[0021] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0022] 1. The thermostatic shower controller of the present application is provided with an adjustment mechanism on the main body, which flexibly regulates the amount of cold water or hot water entering the mixing chamber of the thermostatic valve core through the adjustment mechanism, so that the mixed water in the mixing chamber can quickly reach the preset temperature, providing constant temperature water for users to shower more conveniently and efficiently. In addition, the water volume through the cold water channel and the hot water channel is input into the mixing chamber of the thermostatic valve core, which can effectively prevent the occurrence of cold water and hot water mixing.

[0023] 2. By inletting cold water and hot water at opposite ends, the water inlets of the cold water channel and the hot water channel are set away from each other, and the flow regulating valve provided on the cold water channel path can open and close the cold water channel in real time. The water inlet of the cold water channel is closed when not in use, thereby avoiding the problem of mutual cross-talk between cold and hot water. The flow rate of cold water entering the water outlet channel can be further adjusted. The input of the cold water inlet flow rate can be adjusted at any time according to different needs to achieve a more suitable temperature use effect.

[0024] 3. Both the cold water channel and the hot water channel are equipped with filtering mechanisms, which can greatly reduce the impact of impurities in the water on the water inlet of the shower and enhance the user's shower experience. The operating part of the filtering mechanism allows the user to directly tighten the screw part on the threaded hole of the main body, which is convenient for disassembly, replacement and maintenance. The filter element is inserted into the cross bar in the cold water channel or the hot water channel, and its filtering effect is particularly good.

[0025] 4. An anti-freeze cracking mechanism is installed in the water outlet channel. The anti-freeze cracking mechanism can adaptively absorb or release the water pressure in the water outlet channel to avoid the water in the pipe freezing and bursting the water outlet channel in the main body in a cold environment, causing potential risks such as freezing and cracking of the main body and product leakage, thereby reducing unnecessary economic losses.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] With reference to Figures 1 to 10, this embodiment provides a thermostatic shower controller, comprising a main body 1 equipped with a thermostatic valve core 8. The main body 1 is provided with a cold water channel 3, a hot water channel 2, and a water outlet channel 4. The cold water channel 3 and the hot water channel 2 are mixed in a mixing chamber 81 of the thermostatic valve core 8, and then discharged from the water outlet channel 4. The main body 1 is also provided with a regulating mechanism for adjusting the amount of cold water or hot water entering the mixing chamber 81, thereby quickly ensuring that the mixed water in the mixing chamber 81 reaches the preset temperature of the thermostatic valve core 8.

[0040] In the above, the regulating mechanism is provided on the main body 1, and the amount of cold water or hot water entering the mixing chamber 81 of the thermostatic valve core 8 is flexibly regulated by the regulating mechanism, so that the mixed water in the mixing chamber 81 can quickly reach the preset temperature, and provide constant temperature water for users to shower more conveniently and efficiently. The water volume through the cold water channel 3 and the hot water channel 2 is input into the mixing chamber 81 of the thermostatic valve core 8, which can effectively avoid the occurrence of cold water and hot water mixing.

[0041] In this embodiment, the regulating mechanism is provided in one of the cold water channel 3 or the hot water channel 2, and the regulating mechanism is configured to be suitable for inputting more hot water or less cold water into the mixing chamber 81, so that the mixing chamber 81 can quickly provide constant temperature water to the water outlet channel 4 at a preset temperature.

[0042] In one embodiment, the regulating mechanism is provided on the cold water channel 3 and is used to adjust the amount of cold water entering the mixing chamber 81 so that the mixed water quickly reaches the preset temperature of the thermostatic valve core 8. Thus, the regulating mechanism provided on the cold water channel 3 directly controls the total amount of cold water input into the mixing chamber 81. Especially in cold winter weather, regulating and controlling a smaller amount of cold water to enter the mixing chamber 81 can increase the proportion of hot water, allowing the mixed water in the mixing chamber 81 to quickly reach the preset temperature.

[0043] It should be noted that in other embodiments, the hot water channel 2 may also be provided with the aforementioned regulating mechanism to regulate the amount of hot water entering the mixing chamber 81, thereby increasing the proportion of hot water. Alternatively, regulating mechanisms may be provided separately on the cold water channel 3 and the hot water channel 2 to control the amount of water outputted by their respective channels, both of which fall within the scope of protection of this application.

[0044] Furthermore, the regulating mechanism is a flow regulating valve 7 with an on / off function. In one embodiment, the flow regulating valve 7 has only a closed state and an open state. When closed, the flow regulating valve 7 directly blocks water from flowing into the mixing chamber 81, thereby shutting off the water supply. When opened, the flow regulating valve 7 directly allows water to flow into the mixing chamber 81, thereby opening the water supply.

[0045] In another embodiment, the flow regulating valve 7 has a closed state and an open state with multiple adjustment gears. The amount of water input into the mixing chamber 81 can be more flexibly controlled by adjusting the opening size of different gears.

[0046] As shown in Figures 6 and 7, in this embodiment, the thermostatic valve core 8 is positioned near the hot water channel 2, at the junction of the hot water channel 2, the cold water channel 3, and the water outlet channel 4. A flow control valve 7 is only provided in the cold water channel 3. When the flow control valve 7 is closed, the thermostatic valve core 8 only allows hot water to flow out at a constant temperature, while residual water is discharged from the mixing chamber 81 and the water outlet channel 4. Therefore, after draining the residual water, the shower controller activates the regulating mechanism to allow cold water to enter the mixing chamber 81, quickly bringing the mixed water to the preset temperature.

[0047] As shown in Figures 7 and 8, in this embodiment, one end of the main body 1 is connected to the cold water channel 3 to receive the cold water inlet, and the other end of the main body 1 is connected to the hot water channel 2 to receive the hot water inlet. In addition, the water outlet channel 4 is divided into multiple water channels along the water outlet direction. The main body 1 is provided with a water outlet connector 9 connected to the water channels, and a valve core 10 for independently controlling the water outlet of each water channel to the corresponding water outlet connector 9.

[0048] Thus, by carrying out cold water inlet and hot water inlet at opposite ends, the water inlets of the cold water channel 3 and the hot water channel 2 are set away from each other, and the flow regulating valve 7 is used to open and close the cold water channel 3 for real-time water inlet. The water inlet of the cold water channel 3 is closed when not in use, thereby avoiding the problem of mutual cross-talk between cold and hot water. The flow rate of cold water entering the water outlet channel 4 can be further adjusted, and the input of the cold water inlet flow rate can be adjusted at any time according to different needs to achieve a more suitable temperature use effect.

[0049] In this embodiment, the water outlet channel 4 is arranged transversely within the main body 1, with the cold water channel 3 and hot water channel 2 positioned to the left and right of the water outlet channel 4, correspondingly along the water inlet direction. On one hand, the cold water channel 3 and hot water channel 2 on the left and right sides ultimately connect to the water outlet channel 4, ensuring constant temperature control of the showerhead under the regulation and control of their respective valve cores. On the other hand, the cold water channel 3 is positioned as far away from the hot water channel 2 as possible, significantly reducing the possibility of crosstalk between cold and hot water.

[0050] The flow control valve 7 is located in the cold water channel 3, and the thermostatic valve core 8 is located between the hot water channel 2 and the water outlet channel 4. The thermostatic valve core 8 automatically adjusts the mixing ratio of hot and cold water after the regulating mechanism controls the input water volume, automatically maintaining the temperature of the mixed water at a preset temperature. Obviously, the flow control valve 7, the thermostatic valve core 8, and the valve core member 10 all have existing valve core structures that can be adjusted in opening and controlled in the water channel, and will not be described in detail here.

[0051] In this embodiment, the cold water channel 3 is connected to the cold water end of the thermostatic valve core 8 by a branch 12. The hot water channel 2 is directly connected to the hot water end of the thermostatic valve core 8. The water outlet of the thermostatic valve core 8 is connected to the water outlet channel 4. This configuration allows cold water to be fed to the hot water side of the thermostatic valve core 8 over a longer distance. The thermostatic valve core 8 controls the opening of the cold and hot water sides accordingly, providing water at the desired temperature to the user at its outlet. The water outlet of the thermostatic valve core 8 is closer to the water outlet channel 4 than the water outlet of the flow control valve 7.

[0052] It's worth noting that when the cold water channel 3 is closed, the shower controller implements an energy-saving, optimized "zero cold water" discharge mode. Utilizing the constant temperature characteristics of the thermostatic valve core 8, the cold water in the hot water channel 2 is discharged with absolute priority, achieving a pre-set outlet temperature. When the outlet water temperature reaches the set temperature, the thermistor of the thermostatic valve core 8 automatically closes the hot water channel 2. Once the cold water in the hot water channel 2 has been drained, the flow control valve 7 correspondingly opens the cold water passage, and the thermostatic valve core 8 automatically adjusts the ratio of cold and hot water inflow to output mixed water at the corresponding set temperature. This feature not only reduces temperature adjustment time for consumers but also eliminates the waste of cold water output from the cold water line during initial temperature adjustment, making thermostatic shower systems more time-saving and energy-efficient.

[0053] As shown in Figures 7 and 8, in this embodiment, an anti-freeze cracking mechanism 11 is correspondingly provided in the water outlet channel 4. The anti-freeze cracking mechanism 11 is configured to adaptively absorb or release the water pressure in the water outlet channel 4. Among them, multiple anti-freeze cracking mechanisms 11 are respectively provided along at least the transverse and longitudinal directions of the water outlet channel 4. Anti-freeze cracking mechanisms 11 are correspondingly provided in multiple transverse and longitudinal directions in the water outlet channel 4. The anti-freeze cracking mechanism 11 can adaptively absorb or release the water pressure in the water outlet channel 4, so as to avoid the water in the pipe freezing in a cold environment and bursting the water outlet channel 4 in the main body, causing potential risks such as freezing and cracking of the main body and water leakage of the product, thereby reducing unnecessary economic losses.

[0054] In this embodiment, the anti-freeze crack mechanism 11 includes a fastener 13 docked on one end of the water outlet channel 4, a plug 14 that blocks and faces the water outlet channel 4, and an elastic member 15 connected between the fastener 13 and the plug 14. The elastic member 15 is used to provide an elastic force for the plug 14 to move telescopically. Specifically, by arranging the fastener 13 detachably on the main body, the plug 14 is sealed in the water outlet channel 4. Under the action of the elastic member 15, the plug 14 can press the plug 14 to compress the elastic member 15 when the water pressure in the water outlet channel 4 increases. At this time, energy is stored to absorb the increased water pressure and prevent the pipe from bursting. When the water pressure in the water outlet channel 4 decreases, the elastic member 15 releases the stored energy to reach the initial state, thereby realizing the anti-crack design of the shower pipe.

[0055] Furthermore, the snap fastener 13 is detachably arranged on the side of the main body 1, and the elastic member 15 is configured as an elastic rubber abutting between the snap fastener 13 and the plug 14. The plug 14 can be movably arranged in the water outlet channel 4, and a sealing ring 16 is provided on the plug 14. The elastic rubber has a smaller deformation amplitude and is more suitable for absorbing and releasing water pressure in the pipeline. On the one hand, the seal serves the purpose of watertight sealing, and on the other hand, it also provides resistance to the movement of the plug 14 in the channel. When the plug 14 is squeezed by the expansion of the water volume when the water freezes (or when the external pressure is greater than 0.6Mpa), the corresponding built-in elastic rubber is compressed and the corresponding compressed volume is fully released, thereby reducing the pressure applied to the pipeline due to the expansion of the water volume when the water freezes, preventing damage or bursting of the pipeline. When the ice melts (or is subjected to an external pressure less than 0.6Mpa), the built-in elastic rubber returns to its initial state, thereby ensuring the permanence and applicability of its function.

[0056] The anti-freeze crack mechanism 11 is disposed on the end of the water outlet channel 4 near the water outlet end of the thermostatic valve core 8. Thus, the anti-freeze crack mechanism 11 is disposed in the water inlet direction of the water outlet channel 4, further improving the effectiveness of absorbing and releasing water pressure in the channel.

[0057] As shown in Figures 8 to 10, in this embodiment, a filter mechanism 17 is further provided along the path of the cold water channel 3 and the hot water channel 2. The filter mechanism 17 is detachably mounted on the main body 1 and is located at the cross section of the cold water channel 3 or the hot water channel 2. Thus, the provision of the filter mechanism 17 in both the cold water channel 3 and the hot water channel 2 significantly reduces the impact of impurities in the water on the showerhead's water supply, thereby enhancing the user's showering experience.

[0058] Furthermore, the filter mechanism 17 includes a filter element 18, a threaded connection 19, and an operating portion 20. The main body 1 is provided with a corresponding threaded hole 21 that mates with the threaded connection 19. The operating portion 20 is used to screw the threaded connection 19 into the threaded hole 21, thereby inserting the filter element 18 into the associated channel. The operating portion 20 of the filter mechanism 17 allows the user to directly screw the threaded connection 19 into the threaded hole 21 of the main body 1, facilitating disassembly, replacement, and maintenance. The filter element 18 is inserted into the cold water channel 3 or the hot water channel 2, achieving particularly effective filtering.

[0059] The filter mechanisms 17 are located at the water inlet front ends of the cold water channel 3 and the hot water channel 2 of the shower body 1. Specifically, the filter mechanisms 17 are positioned within the channels near their respective valve cores and on the back of the shower body 1. On the one hand, the proximity of the filter mechanisms 17 to the valve cores lengthens the filtration path. On the other hand, their placement on the back of the showerhead maintains the overall appearance and allows for easy concealment, preventing contamination and damage.

[0060] As shown in Figures 2 to 7, in this embodiment, the flow regulating valve 7 is vertically arranged on the front end side of the main body, the thermostatic valve core 8 is horizontally arranged on the side of the main body, and the cold water inlet connector 5 and the hot water inlet connector 6 are respectively vertically arranged on the rear end side of the main body.

[0061] Among them, multiple valve core members 10 are arranged in parallel on the same side as the flow control valve 7, and multiple water outlet joints 9 are correspondingly arranged on the upper and lower end surfaces of the main body for respectively performing different water outlet functions. Specifically, a water outlet joint 9 is provided on the upper end surface of the main body, and one valve core member 10 is used to control the water outlet joint 9 to discharge water for overhead use. Two water outlet joints 9 are provided on the lower end surface of the shower body, one valve core member 10 is used to control the water outlet joint 9 to discharge water for use in the shower head, and the other valve core member 10 is used to control the water outlet joint 9 to discharge water for use in the faucet.

[0062] Preferably, the cold water inlet connector 5 and the hot water inlet connector 6 are configured as filtered curved pipe fittings, and the water outlet connector 9 is configured as a straight pipe fitting. Obviously, curved pipe fittings are more suitable for compact external connection to the cold and hot water pipes, while straight pipe fittings facilitate directing water out of the shower to the user for daily use.

[0063] In this embodiment, the main body 1 is a flat structure that is connected to an external water system. The main body 1 is applicable to various types of water outlet devices, and such a structural shape is more conducive to the assembly and maintenance of the structural parts, greatly enhancing the core competitiveness of the product.

[0064] Example 2

[0065] This embodiment provides a shower control method, using the above-mentioned constant temperature shower controller, wherein the water outlet temperature is preset by the constant temperature shower controller, and the regulating mechanism is closed in the initial state to disconnect the cold water channel 3 to prevent cold water from entering the mixing chamber 81;

[0066] When entering the use state, the steps are as follows:

[0067] The first step is to open the water outlet channel 4 to discharge the cold water in the hot water channel 2 that is lower than the set temperature, so that the outlet water temperature in the mixing chamber 81 quickly reaches the set temperature;

[0068] In the second step, the amount of cold water in the cold water channel 3 entering the mixing chamber 81 is controlled by the regulating mechanism so that the mixed water in the mixing chamber 81 reaches a preset temperature.

[0069] After the second step is completed, the following two steps are also included:

[0070] The water outlet channel 4 and the regulating mechanism are closed to enter the initial state.

[0071] In this embodiment, after the user has finished use, the water outlet channel 4 and the regulating mechanism can be closed in any order, or closed at the same time to restore them to their initial state, so that when the water outlet channel 4 is opened again, the regulating mechanism can be ensured to close the cold water channel 3.

[0072] Through the above steps, the cold water in the hot water channel 2 can be discharged with absolute priority, achieving a "zero cold water" water outlet effect. At the same time, by controlling the regulating mechanism, the amount of cold water entering the mixing chamber 81 can be adjusted according to the external temperature conditions, so that the mixed water in the mixing chamber 81 can be quickly discharged at a preset temperature.
