Description

Technical Field

[0001] This invention relates to the field of valve technology, and in particular to a water outlet valve and water circuit component system. Background Technology

[0002] The water circuit component system is a type of water heater that uses natural gas as its energy source. It has a powerful central heating function for the home, which can meet the heating needs of multiple rooms, and can also provide domestic hot water for use in places such as bathing and kitchen.

[0003] The water circuit system in related technologies typically includes a combustion chamber, a heat exchange structure, an inlet valve, and an outlet valve. The combustion chamber is usually installed on the indoor wall. The inlet valve supplies water to the combustion chamber. The heat exchange structure includes a heat exchange channel and a water supply channel that are compatible with each other. The outlet valve includes a three-way valve section and a second valve section that are connected to each other. One end of the three-way valve section has a heating water outlet port, and the inlet valve has a heating water inlet port. The heating water inlet port is connected to the combustion chamber through a water pump. Part of the water coming out of the combustion chamber enters the heat exchange channel of the heat exchange structure through the outlet valve, and the other part of the water enters the outlet valve and flows out from the heating water outlet port of the outlet valve to provide hot water for heating to users. The cooled heating water enters the heating water inlet port of the inlet valve and then flows back to the combustion chamber through a water pump. In addition, the inlet valve also includes a domestic water inlet, which connects to an external water source to supply water to the water supply channel of the heat exchange structure. After heat exchange with the heat exchange channel, the water flows into the outlet valve and out from the domestic water outlet to provide hot water for users in their homes, such as for bathing and kitchens. However, in related technologies, the temperature of the water flowing out of the domestic water outlet can only be regulated by the heat exchange efficiency of the heat exchange structure and the initial temperature of the water flowing into the water supply channel of the heat exchange structure. This results in the water flowing out of the domestic water outlet being at a relatively high temperature, affecting the user's water experience.

[0004] Therefore, there is an urgent need to propose a water outlet valve to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a water outlet valve and water circuit component system that can adjust the temperature of hot water flowing from the water outlet valve for use in home bathing, kitchens, and other places, so as to improve the user's water experience.

[0016] The valve body is also provided with a sealing port that connects the cold water flow channel and the mixing chamber, and the adjusting member can adjust the opening degree of the sealing port by moving relative to the valve body.

[0017] As a preferred embodiment of the water outlet valve provided by the present invention, the axial direction of the mixing chamber is set at an angle to the axial direction of the bathroom channel.

[0018] As a preferred embodiment of the water outlet valve provided by the present invention, the angle α between the axial direction of the mixing chamber and the axial direction of the bathroom channel is 5° to 45°.

[0019] As a preferred embodiment of the outlet valve provided by the present invention, the mixing chamber is arranged in an arc shape facing the inner wall of the cold water flow channel; and / or

[0020] The mixing chamber is arranged in an arc shape facing the inner wall of the heat exchange outlet channel.

[0021] As a preferred embodiment of the outlet valve provided by the present invention, the adjusting component is a rotating valve core rotatably disposed in the cold water flow channel.

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0051] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0054] Figure 1 A schematic diagram of the water outlet valve provided by the present invention is shown from one perspective. (See diagram.) Figure 1 As shown, the present invention provides a water circuit component system, which includes a combustion chamber (not shown), a heat exchange structure (not shown), an inlet valve (not shown), and an outlet valve. The heat exchange structure includes a heat exchange channel and a water supply channel that cooperate in heat exchange. The outlet valve includes a valve body 1, which has a non-connected heating channel 10 and a bathroom channel 20. The inlet of the heating channel 10 is connected to the combustion chamber. The valve body 1 also has a heat exchange inlet channel 121 connected to the heating channel 10 and a heat exchange outlet channel 131 connected to the bathroom channel 20. The heat exchange inlet channel 121 is connected to the inlet of the heat exchange channel of the heat exchange structure, and the outlet of the heat exchange channel is connected to the combustion chamber through the inlet valve. The inlet valve can also supply water to the water supply channel, and the outlet of the water supply channel is connected to the heat exchange outlet channel 131. In other words, the hot water heated by the combustion chamber can enter the heat exchange channel of the heat exchange structure through the heating channel 10, and after exchanging heat with the water in the water supply channel, it can flow into the combustion chamber through the inlet valve to form a heat exchange circulation loop; the hot water formed after the water in the water supply channel of the heat exchange structure enters through the inlet valve and exchanges heat with the water in the heat exchange channel can flow into the bathroom channel 20 through the heat exchange outlet channel 131, and the water flowing out from the outlet of the bathroom channel 20 can supply the user's domestic water needs.

[0055] However, in existing technologies, the water temperature flowing out of the bathroom channel outlet can only be adjusted by the heat exchange efficiency of the heat exchange structure and the initial temperature of the water flowing into the water supply channel of the heat exchange structure. This results in a relatively high water temperature flowing out of the bathroom channel outlet valve, affecting the user's water usage experience. To solve the above problems, the present invention also provides a water outlet valve that can adjust the temperature of hot water flowing out of the bathroom channel 20 for use in household bathing, kitchens, and other places, thereby improving the user's water usage experience. The specific structure of the water outlet valve provided by the present invention will be described below through several embodiments.

[0056] Example 1

[0057] Figure 2 A cross-sectional schematic diagram of the water outlet valve provided in this embodiment is shown. Figure 2 and combined Figure 1 As shown, the outlet valve includes a valve body 1 and an adjusting assembly 2. The valve body 1 has a bathroom passage 20 and a heat exchange outlet water passage 131 and a cold water passage 132, both connected to the bathroom passage 20. The heat exchange outlet water passage 131 is connected to the hot water outlet of the heat exchange structure, and the cold water passage 132 is connected to an external water source. The cold water flowing into the cold water passage 132 and the hot water flowing into the heat exchange outlet water passage 131 can mix and flow out from the outlet of the bathroom passage 20. The adjusting assembly 2 includes an adjusting member 21 movably disposed within the valve body 1. By adjusting the relative position of the adjusting member 21 and the valve body 1, the flow rate of the cold water in the cold water passage 132 can be adjusted. It should be noted that the hot water outlet of the heat exchange structure is the outlet of the aforementioned water supply passage.

[0058] The water outlet valve provided in this embodiment has a cold water flow channel 132 connected to the bathroom channel 20 on the valve body 1. Cold water from an external water source can enter the valve body 1 through the cold water flow channel 132 and mix with the hot water flowing into the heat exchange outlet channel 131 before flowing out from the outlet of the bathroom channel 20. This allows for the adjustment of the temperature of the hot water flowing out of the bathroom channel 20 for use in the user's home for bathing, kitchen, and other purposes. An adjusting member 21 that can move relative to the valve body 1 can be installed in the valve body 1. When the adjusting member 21 moves relative to the valve body 1, the flow rate of cold water flowing into the cold water flow channel 132 can be adjusted to regulate the temperature of the hot water flowing out of the bathroom channel 20 for use in the user's home for bathing, kitchen, and other purposes to a set comfortable temperature. The above-mentioned structure is simple, easy to adjust, and improves the user's water experience.

[0059] In this embodiment, the adjusting component 21 is a rotating valve core rotatably disposed within the cold water channel 132. Rotating the rotating valve core adjusts the flow diameter between the cold water channel 132 and the bathroom passage 20, ensuring that cold water and hot water are mixed in a suitable ratio, thereby guaranteeing that the domestic water flowing out of the bathroom passage 20 has a suitable temperature. It should be explained that the flow diameter between the cold water channel 132 and the bathroom passage 20 refers to the channel through which cold water flows between the two channels. The larger the flow diameter, the greater the flow rate of cold water into the cold water channel 132.

[0060] Optionally, the rotary valve core is cylindrical or semi-cylindrical to facilitate its rotation within the valve body 1 and to ensure that its arc-shaped surface remains in contact with the inner wall of the cold water channel 132 near the bathroom channel 20 during rotation, so as to prevent the cold water flowing into the cold water channel 132 from flowing out directly from the outlet of the bathroom channel 20 without mixing with the hot water.

[0061] To achieve the rotation of the rotary valve core, the regulating assembly 2 further includes a regulating drive 22, which is mounted on the valve body 1. The output end of the regulating drive 22 is connected to the rotary valve core to drive it to rotate. In this embodiment, the regulating drive 22 is a servo motor, meaning the regulating assembly 2 is a servo regulating valve, and the valve core of the servo regulating valve forms the aforementioned regulating component 21. Servo regulating valves are a relatively mature technology in the prior art, and the specific structure of the servo regulating valve will not be described in detail in this embodiment.

[0062] Figure 3 A schematic diagram of the outlet valve provided in this embodiment is shown from another perspective. (See diagram below.) Figure 3 and combined Figure 2 As shown, to achieve precise regulation of the water temperature of domestic water flowing out of the bathroom channel 20, the outlet valve also includes a first temperature detection element 31. The first temperature detection element 31 is disposed inside the bathroom channel 20 and is used to detect the temperature of the mixed water in the bathroom channel 20. The first temperature detection element 31 is electrically connected to the regulating component 2. With this arrangement, the regulating component 2 can adjust the relative position of the regulating component 21 with respect to the valve body 1 according to the mixed water temperature detected by the first temperature detection element 31, that is, adjust the flow rate of cold water flowing into the cold water channel 132, thereby achieving precise regulation of the water temperature of the mixed water in the bathroom channel 20. In this embodiment, the first temperature detection element 31 is a thermistor (NTC). Of course, in other embodiments, the first temperature detection element 31 can also be other temperature sensors such as thermocouples or resistance temperature detectors.

[0063] It should be noted that, in this embodiment, the cold water flowing into the valve body 1 through the cold water channel 132 and the hot water flowing into the valve body 1 through the heat exchange outlet channel 131 come into contact at the inlet of the bathroom channel 20 and are fully mixed during the flow in the bathroom channel 20 before flowing out from the outlet of the bathroom channel 20. To ensure the accuracy of the water temperature value of the mixed water obtained by the first temperature sensor 31, the first temperature sensor 31 is set near the outlet of the bathroom channel 20 so that the first temperature sensor 31 obtains the water temperature of the mixed water after the cold water and hot water are fully mixed. This embodiment does not limit the specific location of the first temperature sensor 31 in the bathroom channel 20, and the designer can adjust its location according to the actual situation.

[0064] To further achieve precise regulation of the water temperature of domestic water flowing out of the bathroom channel 20, the outlet valve also includes a second temperature sensor 32. The second temperature sensor 32 is disposed in the heat exchange outlet channel 131 and is used to detect the temperature of the hot water in the heat exchange outlet channel 131. The second temperature sensor 32 is electrically connected to the regulating component 2. By setting the second temperature sensor 32, the temperature of the hot water flowing into the heat exchange outlet channel 131 can be detected. The regulating component 2 can combine the detection results of the first temperature sensor 31 and the second temperature sensor 32 to adjust the relative position of the regulating component 21 relative to the valve body 1, that is, to adjust the flow rate of cold water flowing into the cold water channel 132, further improving the accuracy of water temperature regulation of the mixed water in the bathroom channel 20. In this embodiment, the second temperature sensor 32 is a thermistor (NTC). Of course, in other embodiments, the second temperature sensor 32 can also be other temperature sensors such as thermocouples or resistance temperature detectors (RTDs).

[0065] like Figure 1 and Figure 2 As shown, the axial direction of the heat exchange outlet channel 131 is set at an angle to the axial direction of the cold water channel 132. This arrangement allows the cold water flowing from the cold water channel 132 into the bathroom passage 20 to impact the hot water in the bathroom passage 20 from one side of the axial direction of the heat exchange outlet channel 131, thus achieving a better water mixing effect. In this embodiment, the angle between the axial direction of the heat exchange outlet channel 131 and the axial direction of the cold water channel 132 is 90°. This design maximizes the impact of the cold water on the hot water in the bathroom passage 20, achieving the best water mixing effect. Of course, in other embodiments, the angle between the axial direction of the heat exchange outlet channel 131 and the axial direction of the cold water channel 132 can also be set to 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc.

[0066] To improve the mixing effect of cold and hot water in the bathroom channel 20, in this embodiment, the inner wall of the bathroom channel 20 facing the cold water channel 132 is arc-shaped. When cold water in the cold water channel 132 flows into the bathroom channel 20, it can rotate within the arc-shaped inner wall of the bathroom channel 20, playing a mixing and stirring role, thereby achieving the effect of thorough mixing of cold and hot water.

[0067] Continue as Figures 1-2 As shown, the valve body 1 includes a three-way valve section 11, a first valve section 12, and a second valve section 13. Both the first valve section 12 and the second valve section 13 are formed on one side of the three-way valve section 11 and are spaced apart along the axial direction of the three-way valve section 11. A heat exchange inlet water channel 121 is formed on the first valve section 12. A heating channel 10 is formed within the three-way valve section 11 and the first valve section 12, and the inlet of the heating channel 10 is connected to the burner. A bathroom channel 20 is formed within the second valve section 13, and the aforementioned cold water channel 132 and heat exchange outlet water channel 131 are provided on the side wall of the second valve section 13. Placing the first valve section 12 and the second valve section 13 on the same side of the three-way valve section 11 facilitates the installation of the heat exchange structure.

[0068] Figure 4 A schematic diagram of the outlet valve provided in this embodiment is shown from another perspective. (See diagram below.) Figure 4 and combined Figure 1 and Figure 2 As shown, the heating channel 10 includes a valve chamber 101 located within a three-way valve section 11 and a hot water outlet channel 102 located within a first valve section 12. The three-way valve section 11 also has an inlet port 111 and a heating water outlet port 112. The inlet port 111 communicates with the valve chamber 101 and is connected to the combustion chamber. The heating water outlet port 112 supplies water from the valve chamber 101 to the domestic heating system. The inlet port 111 is positioned opposite to both the heat exchange inlet channel 121 and the heat exchange outlet channel 131 to ensure that the inlet port 111 is not obstructed by the heat exchange structure when connected to the combustion chamber via piping. It should be noted that the inlet of the heating channel 10 is the inlet port 111.

[0069] Figure 5 A schematic diagram of the valve core assembly 4 provided in this embodiment is shown. Figure 5 and combined Figure 2As shown, the outlet valve also includes a valve core assembly 4, which is disposed in the valve cavity 101. The valve cavity 101 is provided with a partition sleeve 113. The valve core assembly 4 cooperates with the partition sleeve 113 to divide the valve cavity 101 into a first cavity 1011, a second cavity 1012, and a heating cavity 1013. The first cavity 1011 is connected to the inlet port 111, the second cavity 1012 is connected to the hot water outlet channel 102, and the heating cavity 1013 is connected to the heating outlet port 112. The valve core assembly 4 can cooperate with the partition sleeve 113 to selectively block the gap between the second cavity 1012 and the first cavity 1011 or the gap between the first cavity 1011 and the heating cavity 1013.

[0070] Specifically, the valve core assembly 4 includes a valve stem 41, a first sealing seat 42, and a second sealing seat 43. The separator sleeve 113 includes a first part 1131 and a second part 1132. The first part 1131 and the second part 1132 are respectively sealed to the inner wall of the valve cavity 101. The first part 1131 is located between the first cavity 1011 and the second cavity 1012, and the second part 1132 is located between the first cavity 1011 and the heating cavity 1013. The first sealing seat 42 can block the first part 1131, and the second sealing seat 43 can block the second part 1132. The valve stem 41 passes through the first sealing seat 42 and the second sealing seat 43 in sequence. The valve stem 41 can move axially along the three-way valve part 11, thereby driving the first sealing seat 42 and the second sealing seat 43 to move axially along the three-way valve part 11. When the valve stem 41 moves upward, the first sealing seat 42 blocks the first part 1131, and the second sealing seat 43 is spaced apart from the second part 1132. At this time, the inlet port 111, the first chamber 1011, the heating chamber 1013, and the heating outlet port 112 are connected. When the valve stem 41 moves downward, the second sealing seat 43 blocks the second part 1132, and the first sealing seat 42 is spaced apart from the first part 1131. At this time, the inlet port 111, the first chamber 1011, the second chamber 1012, the hot water outlet channel 102, and the heat exchange inlet channel 121 are connected, thereby realizing the three-way switching.

[0071] Optionally, the outlet valve further includes a drive mechanism 5, which is located outside the three-way valve section 11 and connected to the valve stem 41. The drive mechanism 5 can drive the valve core assembly 4 to reciprocate up and down. A first elastic element 61 is provided between the first part 1131 and the drive mechanism 5, and a second elastic element 62 is provided between the second part 1132 and the first part 1131. Both the first elastic element 61 and the second elastic element 62 are sleeved outside the valve stem 41 for resetting the valve core assembly 4. In this embodiment, the drive mechanism 5 is a synchronous motor. Of course, in other embodiments, depending on the different designs of the valve core assembly 4, the drive mechanism 5 may also be a stepper motor or other drive modules.

[0072] Example 2

[0073] This embodiment provides a water outlet valve, the structure of which is roughly the same as that of the water outlet valve in Embodiment 1, the difference being that the structure of the valve body 1 is different.

[0074] Figure 6 The diagram shows a schematic of the outlet valve provided in this embodiment from one perspective. Figure 7 A cross-sectional schematic diagram of the water outlet valve provided in this embodiment is shown. Specifically, as... Figures 6-7 As shown, the valve body 1 also includes a mixing chamber 30, which is located between and connected to the heat exchange outlet channel 131 and the cold water channel 132. The outlet of the mixing chamber 30 is connected to the bathroom passage 20. The cold water flowing into the cold water channel 132 and the hot water flowing into the heat exchange outlet channel 131 can be mixed in the mixing chamber 30. The valve body 1 also has a sealing port 133 that connects the cold water channel 132 and the mixing chamber 30. The adjusting member 21 can adjust the opening degree of the sealing port 133 by moving relative to the valve body 1. By providing a mixing chamber 30 in the valve body 1, the cold water flowing into the cold water channel 132 and the hot water flowing into the heat exchange outlet channel 131 can be mixed in the mixing chamber 30, thereby increasing the mixing space for cold and hot water, ensuring that the cold and hot water can be fully mixed before flowing out from the outlet of the bathroom passage 20, and improving the uniformity of the mixing of cold and hot water.

[0075] It should be noted that in this embodiment, both the cold water flowing into the cold water channel 132 and the hot water flowing into the heat exchange outlet channel 131 first flow into the mixing chamber 30 for mixing. To improve the mixing effect, the inner wall of the mixing chamber 30 facing the cold water channel 132 is arc-shaped. When the cold water in the cold water channel 132 flows into the mixing chamber 30, it can rotate within the arc-shaped inner wall of the mixing chamber 30, thus achieving a mixing and stirring effect, and achieving a thorough mixing of the cold and hot water. Of course, in other embodiments, the inner wall of the mixing chamber 30 facing the heat exchange outlet channel 131 can also be arc-shaped to achieve the same effect.

[0076] Optionally, in this embodiment, the distance between the first temperature sensor 31 and the mixing chamber 30 in the bathroom channel 20 is greater than 5mm, so as to ensure that the first temperature sensor 31 obtains the water temperature of the mixed water after the cold water and hot water are fully mixed, thereby improving the accuracy of the detection results obtained by the first temperature sensor 31.

[0077] Figure 8 A schematic diagram of the outlet valve provided in this embodiment is shown from another perspective. Figure 9 It shows Figure 8 Sectional view at AA. (See example) Figures 8-9As shown, in this embodiment, the adjusting member 21 is rotatably disposed at the sealing port 133. When the adjusting drive member 22 is started, it can drive the adjusting member 21 to rotate, so as to adjust the opening degree of the sealing port 133.

[0078] Continue as Figure 7 As shown, the axis of the mixing chamber 30 is set at an angle to the axis of the bathroom channel 20. This design allows the axis of the mixing chamber 30 to be tilted relative to the horizontal plane, thereby increasing the flow path of the mixed water into the bathroom channel 20 and increasing the mixing time of cold and hot water, further ensuring that the two are fully mixed. Optionally, the angle α between the axis of the mixing chamber 30 and the axis of the bathroom channel 20 is 5° to 45°. For example, the angle α between the axis of the mixing chamber 30 and the axis of the bathroom channel 20 can be set to 10°, 12°, 15°, 18°, 20°, 25°, 28°, 30°, 32°, 35°, 38°, 40°, 42°, etc., and designers can adjust the specific value of α according to actual needs.

[0079] Example 3

[0080] This embodiment provides a water outlet valve, the structure of which is roughly the same as that of the water outlet valve in Embodiment 2, the difference being that the structure of the regulating component 2 is different.

[0081] Figure 10 A schematic diagram of the water outlet valve provided in this embodiment is shown. Figure 11 It shows Figure 10 A cross-sectional view at BB. Specifically, as shown... Figures 10-11 and combined Figure 7 As shown, in this embodiment, the adjustment component 2 further includes an adjustment drive component 22 disposed on the valve body 1. The adjustment component 21 includes an adjustment rod 211 and an adjustment valve core 212 sleeved on the adjustment rod 211. One end of the adjustment rod 211 is threaded to the valve body 1, and the other end passes through the valve body 1 and is connected to the output end of the adjustment drive component 22. It can rotate under the driving action of the adjustment drive component 22 so that the adjustment valve core 212 is close to or away from the sealing port 133. The structure is simple and easy to assemble and adjust.

[0082] Optionally, the adjusting rod 211 and the adjusting valve core 212 are integrated into one piece, eliminating the need for assembly of multiple parts, saving assembly time and improving assembly efficiency.

[0083] In this embodiment, a sealing element is also fitted on the regulating valve core 212. The sealing element also has the function of blocking the sealing port 133, so as to stop supplying cold water to the cold water channel 132 when the hot water temperature in the heat exchange outlet channel 131 is low, thereby further improving the user's experience.

[0084] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
