[0028] The realization of the purpose, functional features and advantages of the present utility model will be further described with reference to the accompanying drawings in combination with the embodiments. Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0030] There are mainly two ways to adjust the outlet water temperature of a gas water heater: the first is water heater load adjustment, which realizes the regulation of the outlet water temperature by controlling the gas supply amount of the water heater combustion; the second is water heater water flow adjustment, which realizes the regulation of the outlet water temperature by controlling the water flow of the water heater.

[0031] Existing gas water heaters generally have three structures designed: the first structure realizes the control of the water inlet flow of the water heater by setting a single gas proportional valve. Although this adjustment method has cost advantages, there are certain deficiencies in the adjustment performance. In most cases, it cannot provide the maximum hot water volume for users, and there will also be a situation where the outlet water temperature is too low; the second structure realizes the adjustment of the outlet water temperature by setting a gas proportional valve and an electric water regulating valve. However, during the start and stop process of the water heater, there is still a certain fluctuation in the outlet water temperature, and the outlet water of the water heater will go through a process of cold water, high-temperature hot water, and cold water heating up, affecting the comfort of users using hot water; the third structure realizes the adjustment of the outlet water temperature by setting a gas proportional valve and two electric water regulating valves. Among them, the two electric water regulating valves are respectively used for the water flow adjustment of the main flow channel and the bypass flow channel of the water heater. The coordinated action of the two can improve the comfort of users using hot water, but using one gas proportional valve and two electric water regulating valves will make the volume of the water heater larger and the product cost higher.

[0032] Based on this, the present utility model provides a water regulating valve 10, aiming to achieve the adjustment of the outlet water temperature of the water heater 100, while reducing the volume of the water heater 100 and lowering the product cost.

[0033] Please refer to Figure 1 and Figure 5 , in an embodiment of the present utility model, the water regulating valve 10 includes a valve body 11, a first control component 12 and a second control component 13. The valve body 11 has a water inlet portion 111, and a first water outlet portion 112 and a second water outlet portion 113 that are respectively communicated with the water inlet portion 111; the first control component 12 is disposed on the valve body 11, and the first control component 12 is used for restricting the flow rate of the water flowing through the first water outlet portion 112; the second control component 13 is disposed on the valve body 11, and the second control component 13 is used for adjusting the flow rate of the water flowing through the second water outlet portion 113.

[0034] The water regulating valve 10 includes a valve body 11. The valve body 11 has a water inlet portion 111, a first water outlet portion 112 and a second water outlet portion 113. The water inlet portion 111 and the first water outlet portion 112 are communicated to form the main water path channel of the water regulating valve 10, and the water inlet portion 111 and the second water outlet portion 113 are communicated to form the bypass water path channel of the water regulating valve 10. When applied to the water heater 100, the valve body 11 can be installed on the water inlet pipe 40 of the water heater 100. The water inlet portion 111 is communicated with the water inlet 41 of the water heater 100, the first water outlet portion 112 is communicated with the water inlet end of the heat exchanger 20 of the water heater 100, and the second water outlet portion 113 is communicated with the water inlet end of the bypass pipe 30 of the water heater 100. In this way, a part of the cold water entering from the water inlet 41 of the water heater 100 can be transported to the heat exchanger 20 of the water heater 100 through the main water path channel, and another part of the cold water entering from the water inlet 41 of the water heater 100 can also be transported to the water outlet pipe 50 of the water heater 100 through the bypass water path channel to achieve the bypass mixing function.

[0035] To control the cold water flow rate into the main water passage and the bypass water passage and achieve the adjustment of the outlet water temperature, the valve body 11 is provided with a first control component 12 and a second control component 13. The first control component 12 and the second control component 13 can be arranged outside the valve body 11 or inside the valve body 11. In order to make the water regulating valve 10 form an integrated structure and be more convenient for it to be installed on the water heater 100, in this embodiment, the first control component 12 and the second control component 13 are respectively arranged inside the valve body 11. The first control component 12 is used to limit the flow rate of the water flowing through the first water outlet part 112, that is, the cold water flow rate delivered to the heat exchanger 20 can be limited through the first control component 12, so as to limit the hot water flow rate of the water outlet pipe 50 delivered to the water heater 100. The second control component 13 is used to adjust the flow rate of the water flowing through the second water outlet part 113, that is, the cold water flow rate delivered to the bypass pipe 30 can be adjusted through the second control component 13, so as to adjust the cold water flow rate of the water outlet pipe 50 delivered to the water heater 100. The synergistic effect of the first control component 12 and the second control component 13 enables the mixing amount of hot water and cold water in the water outlet pipe 50 to be changed, so as to achieve the adjustment of the outlet water temperature of the water heater 100 and improve the comfort of users using hot water.

[0036] The technical solution of the present utility model is that the valve body 11 has a water inlet part 111, a first water outlet part 112 and a second water outlet part 113. The water inlet part 111 is communicated with the first water outlet part 112 to form the main water passage of the water regulating valve 10, and the water inlet part 111 is communicated with the second water outlet part 113 to form the bypass water passage of the water regulating valve 10. When applied to the water heater 100, the first water outlet part 112 can be communicated with the water inlet end of the heat exchanger 20 of the water heater 100, and the second water outlet part 113 can be communicated with the water inlet end of the bypass pipe 30 of the water heater 100. In this way, a part of cold water can be delivered to the heat exchanger 20 through the main water passage, and at the same time, another part of cold water can also be delivered to the water outlet pipe 50 of the water heater 100 through the bypass water passage to achieve the bypass mixing function; not only that, by using the first control component 12 to limit the flow rate of the water flowing through the first water outlet part 112 and the second control component 13 to adjust the flow rate of the water flowing through the second water outlet part 113, through the synergistic effect of the two, the outlet water temperature of the water heater 100 can be effectively regulated, and the use comfort of users can be improved. Moreover, in the present utility model, by integrating the first control component 12 and the second control component 13 on a valve body 11 and realizing the regulation of the outlet water temperature through the integrated valve body 11 structure, the overall structure of the water regulating valve 10 is made simpler and more compact, the volume of the water regulating valve 10 is effectively reduced, and it is convenient for its overall installation on the water heater 100.

[0037] There are many implementation forms of the second control component 13, such as Figure 1As shown, in one embodiment, the second control component 13 includes a valve core 131 disposed within the valve body 11. The valve core 131 is provided with a water flow channel 131a and a water passing groove 131b communicating with the water flow channel 131a. The water inlet portion 111 communicates with the second water outlet portion 113 via the water passing groove 131b and the water flow channel 131a. The valve core 131 is movable relative to the valve body 11 to adjust the opening degree of the water passing groove 131b.

[0038] In this embodiment, the valve core 131 is installed within the valve body 11 and is disposed toward the second water outlet portion 113. The valve core 131 extends along a first direction, where the first direction is the height direction of the valve body 11. The valve body 11 is provided with a water flow channel 131a that extends along the first direction. An annular water passing groove 131b is provided on the outer peripheral wall of the valve core 131. The water passing groove 131b communicates with the water flow channel 131a. The water inlet portion 111 communicates with the second water outlet portion 113 via the water passing groove 131b and the water flow channel 131a.

[0039] In practical applications, the valve core 131 can be connected to a mechanical rotating member. Before the mechanical rotating member rotates, the entire notch of the water passing groove 131b faces the water inlet portion 111. When the mechanical rotating member is rotated clockwise manually, the valve core 131 can be driven to rotate clockwise within the valve body 11, such that a part of the notch of the water passing groove 131b is covered by the inner peripheral wall of the valve body 11, that is, the opening degree of the water passing groove 131b becomes smaller, and the cold water flow rate entering the water flow channel 131a from the water inlet portion 111 can be reduced, thereby reducing the cold water flow rate delivered from the second water outlet portion 113 to the bypass pipe 30 and realizing the adjustment of the outlet water temperature. Based on the above-mentioned clockwise rotation situation, when the mechanical rotating member is rotated counterclockwise manually, the valve core 131 can be driven to rotate counterclockwise within the valve body 11, such that the part of the notch covered by the inner peripheral wall of the valve body 11 is exposed and faces the water inlet portion 111, that is, the opening degree of the water passing groove 131b becomes larger, and the cold water flow rate entering the water flow channel 131a from the water inlet portion 111 can be increased, thereby increasing the cold water flow rate delivered from the second water outlet portion 113 to the bypass pipe 30 and realizing the adjustment of the outlet water temperature.

[0040] As Figure 1 As shown, in one embodiment, the second control component 13 further includes a driving assembly 132. The driving assembly 132 is drivingly connected to the valve core 131 to drive the valve core 131 to rotate within the valve body 11, avoiding manual rotation of the valve core 131 and improving the intelligent level of the water regulating valve 10. Optionally, the driving assembly 132 can be implemented by a motor or a cylinder. Among them, the motor can accurately control the speed and position of the movement, can achieve micro-movement, and improve the adjustment accuracy of the outlet water temperature.

[0041] In the case of adding a driving component 132, in order not to excessively increase the volume of the water regulating valve 10, as Figure 1 shown, in one embodiment, the valve body 11 is provided with an installation opening 11a. The valve core 131 has opposite first end 1311 and second end 1312. The first end 1311 is arranged inside the valve body 11 and is in butt communication with the second water outlet part 113, and the second end 1312 passes through the valve body 11 via the installation opening 11a and is in driving connection with the driving component 132.

[0042] In this embodiment, the valve body 11 is provided with an installation opening 11a, and the installation opening 11a is arranged facing the second water outlet part 113. The valve core 131 has opposite first end 1311 and second end 1312 along a first direction. The first end 1311 is arranged inside the valve body 11 and is in butt communication with the second water outlet part 113, and the second end 1312 passes through the valve body 11 via the installation opening 11a and is in driving connection with the driving component 132. In this way, the connection between the valve core 131 and the driving component 132 can be easily realized, and the driving component 132 is installed outside the valve body 11, avoiding the driving component 132 occupying the installation space inside the valve body 11, and at the same time reducing the influence of the water flow inside the valve body 11 on the driving component 132, and improving the service life of the driving component 132. Optionally, the size and shape of the installation opening 11a are generally not limited, mainly for matching installation with the driving component 132.

[0043] As Figure 1 shown, in one embodiment, the first control component 12 further includes a first seal 133. The first seal 133 is arranged between the outer peripheral wall of the first end 1311 and the inner peripheral wall of the valve body 11, and is used for sealing the gap between the first end 1311 and the valve body 11, so as to avoid the uncontrolled change of the water flow rate caused by the uneven gap between the valve core 131 and the valve body 11 during the rotation of the valve core 131, thereby realizing more accurate control of the opening degree of the valve core 131.

[0044] Optionally, the first seal 133 can be realized by using a sealing ring. The sealing ring can be at least one of a V-shaped sealing ring, a U-shaped ring, an O-shaped sealing ring, a rectangular sealing ring, a Y-shaped sealing ring, a YX-shaped hole sealing ring for holes, a YX-shaped retaining ring for holes, a YX-shaped shaft sealing ring, a YX-shaped retaining ring for shafts, an O-shaped rubber sealing ring, an O-shaped sealing ring retaining ring, a J-shaped non-skeleton dust-proof ring. Of course, the type of the sealing ring is not limited to the above types, and it can also be other types of sealing rings, which will not be elaborated one by one here.

[0045] As Figure 1As shown, in one embodiment, the first control component 12 further includes a second seal 134 disposed between the outer peripheral wall of the valve core 131 and the inner peripheral wall of the mounting port 11a for sealing the gap between the valve core 131 and the valve body 11, preventing water flow from leaking from the gap between the valve core 131 and the valve body 11 to the drive assembly 132, thereby reducing the impact of water flow on the drive assembly 132 and achieving protection for the drive assembly 132.

[0046] Optionally, the second seal 134 can also be implemented using a sealing ring. The types of sealing rings have been shown in the above embodiments and will not be repeated here.

[0047] To limit the rotation range of the valve core 131, as Figures 1 to 3 shown, in one embodiment, the second control component 13 further includes a limiting member 135 and a positioning member 136. The limiting member 135 is disposed on the valve body 11 and has a first limiting portion 1351 and a second limiting portion 1352. The positioning member 136 is disposed on the valve core 131. When the valve core 131 rotates, it drives the positioning member 136 to switch between the first limiting portion 1351 and the second limiting portion 1352.

[0048] In this embodiment, the limiting member 135 is implemented using a limiting pressing plate, and the positioning member 136 is implemented using a positioning pin. The limiting member 135 is disposed outside the valve body 11 and faces the mounting port 11a. The limiting member 135 is mainly used to limit the valve core 131 within the valve body 11 to ensure the installation of the valve core 131. The limiting member 135 has a first limiting portion 1351 and a second limiting portion 1352. The positioning member 136 is installed on the valve core 131, and the installation method between the two can be plugging, welding, etc., which is not specifically limited here. In practical applications, when the valve core 131 rotates, the valve core 131 can drive the positioning member 136 to switch between the first limiting portion 1351 and the second limiting portion 1352. For example, when the positioning member 136 switches to the first limiting portion 1351, the valve core 131 rotates to the first position, and the water passing groove 131b on it is completely covered by the inner peripheral wall of the valve body 11, and the bypass water passage of the water regulating valve 10 is in a fully closed state, and the water flow rate of the bypass water passage can reach the minimum; when the positioning member 136 switches to the second limiting portion 1352, the valve core 131 rotates to the second position, and the water passing groove 131b on it is completely exposed and faces the water inlet portion 111, and the bypass water passage of the water regulating valve 10 is in a fully open state, and the water flow rate of the bypass water passage can reach the maximum. That is to say, by setting the limiting member 135 and the positioning member 136, on the one hand, the rotation stroke of the valve core 131 can be limited, and on the other hand, according to the position of the positioning member 136, the rotation position of the valve core 131 and the flow channel characteristics corresponding to this rotation position can be accurately grasped.

[0049] There are many ways to assemble the limiting member 135 and the positioning member 136. For example, Figures 1 to 3 As shown, in an embodiment, the limiting member 135 is provided with a limiting hole 135a for the valve core 131 to pass through. The limiting hole 135a has a first hole wall and a second hole wall. The first limiting portion 1351 is provided on the first hole wall, and the second limiting portion 1352 is provided on the second hole wall. The valve core 131 is provided with a mounting groove 131c. One end of the positioning member 136 is inserted into the mounting groove 131c, and the other end of the positioning member 136 extends into the limiting hole 135a and is used for limiting cooperation with the first limiting portion 1351 or the second limiting portion 1352.

[0050] In this embodiment, a limiting hole 135a for the second end 1312 of the valve core 131 to pass through is provided on one side of the limiting member 135 facing the mounting port 11a. The limiting hole 135a has a first hole wall and a second hole wall that are connected to each other. The first hole wall and the second hole wall are symmetrically arranged along the third direction, where the third direction is the width direction of the limiting member 135. The first hole wall has a first arc segment, and the first arc segment forms the first limiting portion 1351. The second hole wall has a second arc segment, and the second arc segment forms the second limiting portion 1352. The first arc segment and the second arc segment are also symmetrically arranged along the third direction. An outer peripheral wall of the second end 1312 of the valve core 131 is provided with a mounting groove 131c. One end of the positioning member 136 is inserted into the mounting groove 131c to fix the positioning member 136 on the valve core 131. The other end of the positioning member 136 extends into the limiting hole 135a and is used for limiting cooperation with the first arc segment or the second arc segment. In practical applications, when the positioning member 136 is in limiting cooperation with the first arc segment, the valve core 131 rotates to the first position, and the water passing groove 131b on it is completely covered by the inner peripheral wall of the valve body 11, and the bypass water passage of the water regulating valve 10 is in a fully closed state, and the water flow rate of the bypass water passage can reach the minimum; when the positioning member 136 is in limiting cooperation with the second arc segment, the valve core 131 rotates to the second position, and the water passing groove 131b on it is completely exposed and faces the water inlet portion 111, and the bypass water passage of the water regulating valve 10 is in a fully open state, and the water flow rate of the bypass water passage can reach the maximum.

[0051] Such as Figure 1 、 Figure 4 and Figure 5As shown, in one embodiment, the drive assembly 132 is a stepper motor; the water regulating valve 10 further includes a water flow detection assembly 137 for detecting the water inlet flow rate of the water inlet portion 111; the water flow detection assembly 137 and the stepper motor are respectively used for electrically connecting to an electric control assembly 138, and the electric control assembly 138 is used for adjusting the opening degree of the valve core 131 according to the number of steps of rotation of the stepper motor and the water inlet flow rate detected by the water flow detection assembly 137.

[0052] In this embodiment, compared with other types of motors, such as servo motors, etc., the stepper motor can achieve precise position and speed control by controlling the number and frequency of current pulses. Specifically, by controlling the number of steps of rotation of the stepper motor, the rotation angle of the valve core 131 can be precisely controlled, and then the opening degree of the valve core 131 can be precisely controlled to achieve precise control of the outlet water temperature. To achieve the precise control proposed above, the water regulating valve 10 further includes a water flow detection assembly 137. The water flow detection assembly 137 can be implemented by a water flow sensor, and the model and source of the water flow sensor are not limited here. The water flow detection assembly 137 is used for detecting the water inlet flow rate passing through the water inlet portion 111. Among them, the water inlet flow rate passing through the water inlet portion 111 is the total water volume of the water heater 100, mainly including the sum of the hot water flow rate passing through the heat exchanger 20 of the water heater 100 and the cold water flow rate passing through the bypass pipe 30 of the water heater 100.

[0053] It should be noted that the water flow detection assembly 137 and the stepper motor can be used to electrically connect to the electric control assembly 138. Among them, the electric control assembly 138 can be the control center of the water regulating valve 10 or the control center of the water heater 100. In this embodiment, taking the electric control assembly 138 as the control center of the water heater 100 as an example, the electric control assembly 138 can be implemented by at least one of a controller, a control chip, and a PCB board. The electric control assembly 138 is electrically connected to the water flow detection assembly 137 and the stepper motor respectively. The electric control assembly 138 can accurately know the rotation position of the valve core 131 through the number of steps of rotation of the stepper motor, and then know the cold water flow rate delivered to the bypass pipe 30 of the water heater 100. That is to say, as long as the total water volume of the water heater 100 and the rotation position of the valve core 131 are known, the cold water flow rate passing through the bypass pipe 30 and the hot water flow rate passing through the heat exchanger 20 can be judged, which is convenient for the electric control assembly 138 to precisely control the outlet water temperature of the water heater 100.

[0054] In addition, the electronic control component 138 can also determine that when the outlet water temperature of the heat exchanger 20 is too high based on the hot water flow rate through the heat exchanger 20 and the total water volume of the water heater 100. By adjusting the rotation position of the valve core 131, the opening degree of the water passing trough 131b can be reduced, so that more cold water is delivered to the heat exchanger 20 through the first water outlet part 112, thereby reducing the outlet water temperature of the heat exchanger 20 and ensuring the service life and reliability of the heat exchanger 20.

[0055] As Figure 1 shown, in an embodiment, the first control component 12 is a flow limiting ring, and the flow limiting ring is arranged on the first water outlet part 112 and is used to limit the water flow rate delivered from the first water outlet part 112 to the heat exchanger 20 of the water heater 100 under different water pressures, and indirectly adjust the outlet water temperature of the water heater 100.

[0056] As Figure 5 shown, the present utility model also provides a water heater 100. The water heater 100 includes a water mixing valve 10. The specific structure of the water mixing valve 10 refers to the above embodiments. Since the water heater 100 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one.

[0057] Among them, the water heater 100 further includes a gas proportional valve, a heat exchanger 20, and a bypass pipe 30. The water heater 100 has a water inlet 41 and a water outlet 51. The water inlet part 111 of the water mixing valve 10 is communicated with the water inlet 41. The first water outlet part 112 of the water mixing valve 10 is communicated with the water inlet end of the heat exchanger 20. The second water outlet part 113 of the water mixing valve 10 is communicated with the water inlet end of the bypass pipe 30. The water outlet end of the bypass pipe 30 and the water outlet end of the heat exchanger 20 are respectively communicated with the water outlet 51. The water heater 100 further includes an electric control assembly 138. The second control component 13 can be electrically connected to the electric control assembly 138, and the electric control assembly 138 is used to control the second control component 13 to automatically adjust the water flow rate of the second water outlet part 113. For example, the second control component 13 includes a driving assembly 132 and a valve core 131. The electric control assembly 138 is electrically connected to the driving assembly 132. Thus, when the water heater 100 is first turned on, the electric control assembly 138 can control the driving assembly 132 to drive the valve core 131 to rotate to the first position, and the water passing groove 131b thereon is completely covered by the inner peripheral wall of the valve body 11. The bypass water channel of the water mixing valve 10 is in a fully closed state, and the external cold water is directly transported to the first water outlet part 112 through the water inlet part 111 and then transported to the heat exchanger 20 through the first water outlet part 112, so that the water heater 100 can quickly supply hot water. When the water outlet temperature of the water heater 100 is stable, if the gas proportional valve of the water heater 100 does not reach the maximum gas supply volume, the electric control assembly 138 can control the driving assembly 132 to drive the valve core 131 to gradually rotate from the first position to the second position, so as to ensure the maximum water consumption of the user. When the water heater 100 stops in the middle and is turned on again in a short time, by adjusting the opening degree of the valve core 131 and means such as quick ignition of the water heater 100, the water outlet temperature of the water heater 100 can be maintained in a stable state, thereby improving the comfort of the user using hot water.

[0058] As Figure 5 shown, in an embodiment, the water heater 100 further includes a water inlet pipe 40 and a water outlet pipe 50. The water inlet pipe 40 includes a first water outlet end and a second water outlet end. The water mixing valve 10 is installed on the water inlet pipe 40. The water outlet pipe 50 includes a first water inlet end and a second water inlet end. The first water outlet end is communicated with the water inlet end of the heat exchanger 20. The first water inlet end is communicated with the water outlet end of the heat exchanger 20. The bypass pipe 30 communicates the second water outlet end and the second water inlet end.

[0059] As Figure 5 shown, in an embodiment, the water heater 100 further includes a temperature detection component 60, and the temperature detection component 60 can be implemented by a temperature sensor. The temperature detection component 60 is installed on the water outlet pipe 50, mainly used to detect the water outlet temperature passing through the water outlet pipe 50 and feedback it to the electric control assembly 138, so that the electric control assembly 138 adjusts the rotation position of the valve core 131 according to the detected water outlet temperature, so as to limit the water outlet temperature of the water heater 100 within a certain range and ensure the comfort of the user using hot water.

[0060] The above are only some embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
