Technical Field

[0001] This invention relates to the field of gas water heater technology, and in particular to a dual-function health bath device, a gas water heater and its control method. Background Technology

[0002] With societal development, healthy bathing has become a key consideration for consumers when choosing water heaters. Currently, some water heaters on the market incorporate a skin-beautifying water purification tank within the unit's water circuit. This tank uses aromatherapy essential oils, vitamin C gel, and other skin-beautifying and water-purifying materials to enhance the bathing experience. However, long-term use of such devices may lead to water quality deterioration, contradicting the original intention of healthy bathing. Therefore, there is an urgent need for a gas water heater with a dual-function healthy bathing module and its control method. Summary of the Invention

[0003] Therefore, it is necessary to provide a dual-function health bath device, a gas water heater, and a control method thereof to address the aforementioned technical problems.

[0004] Firstly, a dual-function health bath device is provided, comprising:

[0005] A flow channel module, comprising a housing, an inlet flow channel cavity and an outlet flow channel cavity located inside the housing, wherein the inlet flow channel cavity and the outlet flow channel cavity are not connected;

[0006] A water circuit solenoid valve, wherein the water circuit solenoid valve is inserted into the water outlet flow channel cavity and fixed to the inner side of the housing;

[0009] When the water circuit solenoid valve is in the closed state, the fluid flows out of the dual-function health bath valve core through the first filter media chamber. When the water circuit solenoid valve is in the open state, part of the fluid flows out of the dual-function health bath valve core through the first filter media chamber, and the other part flows through the first filter media chamber and the second filter media chamber in sequence before flowing out of the dual-function health bath valve core.

[0010] As an optional implementation, the dual-function health bath valve core further includes:

[0011] The valve core body includes an outer shell, an inner shell, and a connecting ring band connecting the outer shell and the inner shell. The outer shell and the connecting ring band surround to form a first filter media cavity, and the inner shell and the connecting ring band surround to form a second filter media cavity. A through hole is opened at the lower part of the outer shell, and the inner shell is located at the upper inner side of the valve core body.

[0034] Thirdly, a control method for a gas water heater as described in the second aspect is provided, the method comprising:

[0035] Get the current water flow rate and the current total water consumption;

[0036] If the current water flow rate is greater than the preset water flow rate threshold and the current total water consumption is less than the preset total water consumption threshold, then the health bath function of the dual-function health bath device is determined to be available, and the water circuit solenoid valve of the dual-function health bath device is opened when the user's health bath start command is received.

[0037] If the current water flow rate is less than or equal to the preset water flow rate threshold, the health bath function is determined to be unavailable, and a blockage alarm is output.

[0038] If the current total water consumption is greater than or equal to the preset total water consumption threshold, the health bath function is determined to be in an unavailable state, and a filter replacement alarm is output.

[0056] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the accompanying drawings. Figures 1 to 8 This application will be described in further detail below. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0057] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0058] The dual-function health bath device of this invention includes: a flow channel module 1, a water circuit solenoid valve 2, a water cup 3, and a dual-function health bath valve core 4. The dual-function health bath valve core 4 includes a first filter media chamber 41 and a second filter media chamber 42 that are interconnected. When the water circuit solenoid valve 2 is closed, fluid flows out of the dual-function health bath valve core 4 through the first filter media chamber 41. When the water circuit solenoid valve 2 is open, part of the fluid flows out of the dual-function health bath valve core 4 through the first filter media chamber 41, and the other part flows sequentially through the first filter media chamber 41 and the second filter media chamber 42 before exiting the dual-function health bath valve core 4.

[0059] Figure 1 This is a schematic diagram of the structure of a dual-function health bath device provided in an embodiment of this application, as shown below. Figure 1As shown, the dual-function health bath device includes a flow channel module 1, a water circuit solenoid valve 2, a water cup 3, and a dual-function health bath valve core 4. The water circuit solenoid valve 2 is inserted into the water outlet flow channel cavity 13 and fixed to the inner side of the housing 11 of the flow channel module 1 (see details). Figure 3 The water cup 3 can be connected to the bottom of the housing 11. Specifically, the lower part of the housing 11 is provided with an internal thread, and the upper part of the water cup 3 is provided with an external thread. The water cup 3 and the housing 11 are connected by a threaded rotation. After the water cup 3 and the housing 11 are connected, a cavity is formed. The dual-function health bath valve core 4 is set in the cavity formed by the housing 11 and the water cup 3. Since the water cup 3 is detachable, the user can replace the dual-function health bath valve core 4 by removing the water cup 3, which is very convenient.

[0060] Figure 2 This is a bottom view of the flow channel module structure provided in the embodiments of this application, as shown below. Figure 2 As shown, the flow channel module 1 includes a housing 11, an inlet flow channel cavity 12 and an outlet flow channel cavity 13 located inside the housing 11, an inlet 14, and an outlet 15. The inlet flow channel cavity 12 and the outlet flow channel cavity 13 can be designed as double-layered structures that are not interconnected. The inlet 14 is located on the housing 11 and connects to the inlet flow channel cavity 12. The outlet 15 is also located on the housing 11 and connects to the outlet flow channel cavity 13. Figure 2 As shown by the dashed arrow, water flows from the inlet 14 into the inlet channel cavity 12 along the direction of the arrow, and then flows downward into the dual-function health bath valve core 4 (see details of the flow method into the dual-function health bath valve core 4). Figure 6 Water flowing from the dual-function health bath valve core 4 flows upward into the water outlet cavity 13 and flows out of the outlet 15 along the direction of the dotted arrow.

[0061] Figure 3 A side sectional view (cut along the direction of water outlet 15) of the water circuit solenoid valve and flow channel module provided in the embodiments of this application, as shown. Figure 3 As shown, the lower part of the solenoid valve body 21 of the water circuit solenoid valve 2 is provided with a closing member 22, and first connecting members 23 are provided on both sides of the closing member 22. Screw holes (or other connection methods) can be provided on the connecting members. The upper part of the housing 11 of the flow channel module 1 is provided with a second connecting member 16, which has a housing through hole 111 communicating with the water outlet flow channel cavity 13. Screw holes can also be provided on the second connecting member 16 so that when the water circuit solenoid valve 2 is inserted into the flow channel module 1, the water circuit solenoid valve 2 and the flow channel module 1 can be fixed together by screws.

[0062] Figure 7 This is a schematic diagram of the on / off state of the water circuit solenoid valve provided in the embodiments of this application (the side section in the figure is cut along the direction of water outlet 15), as shown. Figure 7As shown in Figure 7a, the water circuit solenoid valve 2 is in the closed state, and the closing element 22 blocks the through hole 441. After the fluid flows into the second filter media chamber 42, it cannot pass through the through hole 441, thereby preventing the fluid from flowing out of the second filter media chamber 42 from the dual-function health bath valve core 4. Figure 7 As shown in Figure 7b, the water circuit solenoid valve 2 is in the open state, and the valve body 21 of the solenoid valve drives the closing member 22 to lift, so that the second filter media chamber 42 is connected to the water outlet flow channel chamber 13.

[0063] Figure 4 This is a schematic diagram of the structure of the dual-function health bath valve core provided in the embodiments of this application, as shown below. Figure 4 As shown, the dual-function health bath valve core 4 includes a first filter media chamber 41, a second filter media chamber 42, a valve core body 43, a valve body cover 44, a valve body base 45, and a filter screen 46. The valve core body 43 is a cylindrical body with an L-shaped groove at its lower part. The valve body base 45 has the same cross-sectional area as the valve core body 43, and a protrusion at its upper part. When the valve body base 45 is fastened to the bottom of the valve core body 43, the protrusion at the upper part of the valve body base 45 enters the L-shaped groove at the lower part of the valve core body 43. Rotating the valve body base 45 along the direction of the L-shaped groove allows it to engage with the valve core body 43. The valve core body 43 includes an outer shell 431, an inner shell 432, and a connecting ring 433 connecting the outer shell 431 and the inner shell 432. Both the outer shell 431 and the inner shell 432 are cylindrical. The cross-sectional diameter of the inner shell 432 is smaller than that of the outer shell 431, and the height of the inner shell 432 is approximately half that of the outer shell 431. The connecting ring 433 is a slightly concave disc-shaped object with a groove around its inner wall to hold the edge of the connecting ring 433 in place. The outer shell 431 and the connecting ring 433 surround each other to form the first filter media chamber 41, and the inner shell 432 and the connecting ring 433 surround each other to form the second filter media chamber 42. The lower part of the outer shell 431 has 12 evenly arranged rectangular through holes 4311. The inner shell 432 is located on the upper inner side of the valve core body 43. The valve body cover 44 is detachably connected to the upper part of the inner shell 432 to close the upper part of the second filter media chamber 42. The filter screen 46 is disposed on the lower inner side of the outer shell 431 and covers the through holes 4311. The connecting ring band 433 includes a water passage groove 4331 and a water passage hole 4332. The water passage groove 4331 is located on the connecting ring band 433 between the outer shell 431 and the inner shell 432, and the water passage hole 4332 is located on the connecting ring band 433 inside the inner shell 432. The water passage hole 4332 is used to prevent the functional substances in the second filter media chamber 42 from coming into contact with the first filter media chamber 41 without affecting the fluid flow. This application achieves the function of one core with two chambers through the innovative structural design of the dual-function health bath valve core, which can meet the simultaneous placement of two types of filter media.

[0064] Figure 5 This is a schematic diagram of the structure of the valve body cover provided in an embodiment of this application, as shown below. Figure 5 As shown, the valve body cover 44 includes a through hole 441 and a cover filter 442. The through hole 441 is located in the middle of the valve body cover 44, and the cover filter 442 is located on the lower side of the valve body cover 44 and covers the through hole 441.

[0065] Figure 6 This is a side sectional view of the dual-function health bath device provided in the embodiments of this application (cut along the direction of the water inlet 14), as shown. Figure 6 As shown, the outer wall of the outer shell 431, the inner wall of the shell 11, and the inner wall of the water cup 3 form a water inlet channel 5. The inner wall of the outer shell 431 and the outer wall of the inner shell 432 form a water outlet channel 6. Fluid sequentially enters the first filter media chamber 41 through the inlet 14, the inlet channel 12, the inlet channel 5, and the filter screen 46. After being descaled in the first filter media chamber 41, part of the fluid flows through the water passage 4331 and the outlet channel 6 into the outlet channel 13 and exits from the outlet 15. The other part enters the second filter media chamber 42 through the water passage hole 4332. After being enriched with strontium in the second filter media chamber 42, the fluid flows through the upper cover filter screen 442 and the through hole 441 into the outlet channel 13 and exits from the outlet 15. Figure 6 (Not shown in the image; from the current perspective, outlet 15 is located on the opposite side of the viewer) from which water flows out.

[0066] Optional, such as Figure 1-7 As shown, to ensure sealing, the water cup 3 has a groove, and a sealing rubber ring is installed in the groove. The valve body cover 44 has a groove, and a sealing rubber ring is installed in the groove. The water circuit solenoid valve 2 has a groove, and a sealing rubber ring is installed in the groove. The outer casing 431 has a groove, and a sealing rubber ring is installed in the groove.

[0067] Figure 8 This is a schematic diagram of the structure of a gas water heater provided in an embodiment of this application, as shown below. Figure 8As shown, the gas water heater includes a gas water heater body 810 and a dual-function health bath device 820 as described in any one of claims 1 to 8. The inlet pipe 811 of the gas water heater body is connected to the outlet 821 (same as outlet 15 above) of the dual-function health bath device, and the inlet 822 (same as inlet 14 above) of the dual-function health bath device is connected to a tap water pipe 830. The controller 812 in the gas water heater body is electrically connected to the water circuit solenoid valve 823 (same as water circuit solenoid valve 2 above) of the dual-function health bath device. The controller 812 is used to control the on / off state of the water circuit solenoid valve 823 to switch the health bath function of the dual-function health bath device 820 between available and unavailable states.

[0068] Figure 9 A flowchart of a control method for a gas water heater provided in this application embodiment is shown below. Figure 9 As shown, the specific steps are as follows:

[0069] Step 901: Obtain the current water flow rate and the current total water consumption.

[0070] During implementation, after the system is powered on, such as Figure 8 As shown, the gas water heater obtains the current water flow rate L1 and the current total water consumption in real time through the water flow sensor 813. Among them, the current total water consumption V1 is the total water flow rate accumulated by the gas water heater during a single water flow using a clock timing scheme and the total water flow rate recorded by the internal storage chip since the water heater was used.

[0071] Step 902: Determine whether the current water flow rate is greater than the preset water flow rate threshold.

[0072] If the gas water heater determines that the current water flow is greater than the preset water flow threshold, then proceed to step 904; otherwise, proceed to step 903.

[0073] Step 903: Determine that the health bath function is in an unavailable state and output a blockage alarm prompt.

[0074] In practice, the gas water heater stores the water flow rate L when the user first uses the water heater. 首 Gas water heaters are based on water flow rate L 首 The difference ΔL between the current water flow rate L1 and the current water flow rate L1 can be determined, and it can be stipulated that ΔL ≥ 1 / 2 * L 首 When the gas water heater's output pipe is blocked, an alarm will sound, and the "Health Bath" function will be unavailable. This can be understood as △L ≥ 1 / 2 * L. 首 That is, 1 / 2 * L 首 ≥L1 indicates that the current water flow rate L1 is less than or equal to the water flow rate L when the user first uses the water heater. 首If half the flow rate is insufficient, there will inevitably be a blockage in the pipes. To ensure smooth water supply for users, the gas water heater controller disables the "health bath" function of the dual-function health bath device, allowing users to use only the regular shower function. The gas water heater can also output a blockage alarm to remind users to repair the pipes promptly. Technicians can determine the water flow rate (L) when the user first uses the water heater. 首 Half of the water flow rate is set as a preset water flow threshold and stored in the gas water heater.

[0075] Step 904: Determine whether the current total water consumption is less than the preset total water consumption threshold.

[0076] If the gas water heater determines that the current total water consumption is less than the preset total water consumption threshold, then proceed to step 906; otherwise, proceed to step 905.

[0077] Step 905: Determine that the health bath function is set to an unavailable state and output a filter replacement alarm prompt.

[0078] In practice, since the dual-function health bath valve core has a service life, technicians have pre-stored a total water consumption threshold in the gas water heater. If the gas water heater determines that the current total water consumption is greater than or equal to the preset total water consumption threshold, the gas water heater determines that the health bath function is set to an unavailable state and outputs a core replacement alarm prompt to remind the user to replace the core in time.

[0079] Step 906: Determine whether the user's health bath start command has been received.

[0080] If the gas water heater receives the user's "Health Bath" activation command, proceed to step 908; otherwise, proceed to step 907.

[0081] Step 907, Normal Shower Mode.

[0082] Step 908: Open the water circuit solenoid valve of the dual-function health bath device to enter the health bath mode.

[0083] In practice, if the gas water heater determines that the current water flow is greater than the preset water flow threshold and the current total water consumption is less than the preset total water consumption threshold, when the gas water heater receives the user's health bath activation command, the gas water heater controller controls the water circuit solenoid valve of the dual-function health bath device to open, so that the health bath substance enters the user's water to achieve the effect of health care.
