Description

TECHNICAL FIELD

[0001] The utility model relates to a valve technical field, concretely relates to a water inlet and outlet valve group. BACKGROUND

[0002] The wall-hanging stove water system is a water heater taking natural gas as energy, which has a powerful home central heating function, can satisfy the heating demand of multiple rooms, and can provide domestic water for household bathing, kitchen and other places. The water inlet valve and the water outlet valve are both indispensable structures in the wall-hanging stove water system. The main function of the water inlet valve is to regulate the water flow entering the wall-hanging stove, ensure the normal operation of the wall-hanging stove, and automatically start when the water in the wall-hanging stove is insufficient to add water to the wall-hanging stove, thereby ensuring the continuity of hot water supply. The main function of the water outlet valve is to control the opening and closing of the water inlet and outlet, shunt and control the direction of water flow, thereby ensuring the uniform delivery of hot water in the pipeline and the normal heating of the heating panel.

[0003] In the related art, the bypass flow channel of the water outlet valve is used to selectively communicate the heating channel and the heat exchange inlet channel to supplement water in time when the heating waterway is short of water. However, when the bypass flow channel is opened, the water in the heating channel will flow to the heat exchange plate through the heat exchange inlet channel, and then flow to the combustion chamber from the water pump interface of the water inlet valve to complete the water supplement operation. In this water supplement process, on the one hand, the water flowing into the heat exchange plate will exchange heat with the bath water therein, resulting in heat loss. When the heat-exchanged water flows into the combustion chamber to be reheated, the heating time is relatively long, which will cause resource waste. On the other hand, the water flowing from the heating channel to the heat exchange plate has a high temperature. When the temperature of the bath water in the heat exchange plate is low, the sealing element at the connection between the water outlet valve and the heat exchange plate will be rapidly heated, causing rapid expansion of the sealing element, which has a risk of leakage.

[0004] Therefore, there is an urgent need for a water inlet and outlet valve group to solve the above problems. UTILITY MODEL CONTENT

Figure 2 A second view of the wall-hanging stove waterway system provided by the present embodiment is shown. Figures 1-2 As shown, the present embodiment provides a wall-hanging stove waterway system, which comprises a heat exchange structure 200 and an inlet and outlet water valve group 100.

The three-way valve part 11 is located between the heat exchange valve part 12 and the inlet water valve part 13. The heat exchange valve part 12 and the inlet water valve part 13 are used to connect the heat exchange structure 200.

[0051] It should be particularly noted that, as shown, Figure 1 The height direction of the inlet and outlet water valve group 100 after actual installation is defined as the up-down direction. The side of the inlet and outlet water valve group 100 close to the combustion chamber is defined as the upper side, the side of the inlet and outlet water valve group 100 away from the combustion chamber is defined as the lower side, the side of the inlet and outlet water valve group 100 close to the heat exchange structure 200 is defined as the back side, and the side of the inlet and outlet water valve group 100 away from the heat exchange structure 200 is defined as the front side. When the user stands facing the front of the inlet and outlet water valve group 100, the side of the inlet and outlet water valve group 100 facing the user's right hand is defined as the right side, and the side of the inlet and outlet water valve group 100 facing the user's left hand is defined as the left side. In the present embodiment, the height direction of the inlet and outlet water valve group 100 is the up-down direction, the width direction of the inlet and outlet water valve group 100 is the left-right direction, and the thickness direction of the inlet and outlet water valve group 100 is the front-back direction.

[0052] The wall-hanging stove water system provided by the embodiment has the valve body 1 of the inlet and outlet valve group 100 in an integrated structure, so that only one set of mold needs to be designed and processed during processing, the processing process is simplified, the processing efficiency is improved, the assembly process of the heat exchange structure 200 and the inlet and outlet valve group 100 is simplified, and the assembly efficiency is improved; the three-way valve part 11 is arranged between the heat exchange valve part 12 and the water inlet valve part 13, so that the arrangement space between the heat exchange valve part 12 and the water inlet valve part 13 can be fully utilized, compared with the prior art, the size of the inlet and outlet valve group 100 exceeding the heat exchange structure 200 in the width direction is greatly reduced, so that the size of the entire wall-hanging stove water system in the width direction is reduced, and the miniaturization requirement of the wall-hanging stove water system is met.

[0053] Figure 3 The structure diagram of the heat exchange structure 200 provided by the embodiment is shown. Figure 4 The first view of the inlet and outlet valve group 100 provided by the embodiment is shown. Figures 3-4 And combined with Figure 2 As shown in the figure, the heat exchange structure 200 includes heat exchange channels (not shown in the figure) and water supply channels (not shown in the figure) matched with each other, the three-way valve part 11 has a hot water inlet 111 and a heating channel 112, the heat exchange valve part 12 has a first heat exchange inlet flow channel 121, a first heat exchange outlet flow channel 122 and a bathroom channel 123, the hot water inlet 111 is connected with a hot water outlet of a combustion chamber, and the hot water inlet 111 can selectively communicate with the heating channel 112 or the first heat exchange inlet flow channel 121, the first heat exchange inlet flow channel 121 and the first heat exchange outlet flow channel 122 are connected with a heat exchange inlet 2011 of the heat exchange channel and a water supply outlet 2022 of the water supply channel respectively, and the first heat exchange outlet flow channel 122 is connected with the bathroom channel 123; the water inlet valve part 13 has a water inlet interface 131, a second heat exchange inlet flow channel 133, a second heat exchange outlet flow channel 134 and a water pump interface 132, the water inlet interface 131 is connected with an external water source, the second heat exchange outlet flow channel 134 is connected with the water pump interface 132, the second heat exchange inlet flow channel 133 is connected with the water inlet interface 131, and the second heat exchange inlet flow channel 133 and the second heat exchange outlet flow channel 134 are connected with a water supply inlet 2021 of the water supply channel and a heat exchange outlet 2012 of the heat exchange channel respectively, and the water pump interface 132 is connected with a cold water inlet of the combustion chamber through a water supply pump (not shown in the figure).

[0054] In working, when the hot water inlet 111 is communicated with the heating passage 112, the hot water heated by the combustion chamber can flow to the heating system in sequence through the hot water inlet 111 and the heating passage 112, so as to provide the heating requirement for the user. The water in the heating system which is heat-exchanged with the outside can flow to the combustion chamber through the water inlet valve part 13 to be heated again, so as to form a heating water circulation loop. When the hot water inlet 111 is communicated with the first heat-exchange inlet channel 121, the hot water heated by the combustion chamber can flow to the heat-exchange passage of the heat-exchange structure 200 in sequence through the hot water inlet 111 and the first heat-exchange inlet channel 121. After being heat-exchanged with the water in the water supply channel, the hot water flows to the second heat-exchange outlet channel 134 of the water inlet valve part 13, and then flows back to the combustion chamber through the water pump interface 132 to be heated again, so as to form a heat-exchange circulation loop. The water in the external water source can flow into the water supply channel of the heat-exchange structure 200 through the water inlet interface 131 and the second heat-exchange inlet channel 133. After being heat-exchanged with the water in the heat-exchange passage, the water flows to the bathroom system in sequence through the first heat-exchange outlet channel 122 of the heat-exchange valve part 12 and the bathroom passage 123, so as to provide the user with the domestic water.

[0055] It should be explained that the heating system specifically refers to the terminal heat dissipation components such as heating radiators, floor heating pipes or fan coil units. The water heated in the combustion chamber can be pumped to the above-mentioned terminal heat dissipation components through the water inlet and outlet valve group 100, and the heat is dissipated to the indoor air through heat dissipation, so as to improve the indoor environment temperature and meet the heating requirement of the user. The bathroom system specifically refers to the water device for the user to perform shower, washing and other operations. Therefore, the heating system and the bathroom system are both relatively mature technologies in the field, and the specific structure of the heating system and the bathroom system will not be described herein.

[0056] It should be explained that the combustion chamber is a relatively mature technology in the field, and the specific structure of the combustion chamber will not be described herein.

[0057] In order to ensure the sealing performance of the water connection between the heat-exchange valve part 12 and the heat-exchange structure 200 and between the water inlet valve part 13 and the heat-exchange structure 200, the sealing members are arranged between the outlet of the first heat-exchange inlet channel 121 and the heat-exchange inlet 2011, between the inlet of the first heat-exchange outlet channel 122 and the water supply outlet 2022, between the outlet of the second heat-exchange inlet channel 133 and the water supply inlet 2021, and between the inlet of the second heat-exchange outlet channel 134 and the heat-exchange outlet 2012, so as to avoid leakage at each connection position and affect the use safety of the entire wall-mounted stove water system. Optionally, the sealing member can be an O-ring or a star-shaped ring. The specific number of the sealing members at each connection position is not limited in the embodiment, and the designer can adjust the specific number of the sealing members according to the actual requirement.

[0058] Figure 5 A first sectional view of the water inlet and outlet valve group 100 provided in the embodiment is shown. As shown in FIG. 1, the water inlet and outlet valve group 100 comprises a heat-exchange valve part 12 and a water inlet valve part 13. Figure 5And combined Figure 4 As shown in the figure, the three-way valve part 11 also has a three-way valve cavity 110, which includes a first cavity 1102, a main valve cavity 1101 and a second cavity 1103 in turn communicated along the axial direction, the main valve cavity 1101 is communicated with the hot water inlet 111, and the main valve cavity 1101 can selectively communicate the first cavity 1102 or the second cavity 1103; the heating channel 112 is communicated with the first cavity 1102, and the first heat exchange inlet flow channel 121 is communicated with the second cavity 1103. When the main valve cavity 1101 is communicated with the first cavity 1102, the hot water in the combustion chamber can circulate in the heating water circulation loop; when the main valve cavity 1101 is communicated with the second cavity 1103, the hot water in the combustion chamber can circulate in the heat exchange circulation loop.

[0059] Optionally, the water inlet and outlet valve group 100 also includes a switching mechanism 2, which is movably arranged in the three-way valve cavity 110, so as to selectively communicate the heating channel 112 or the first heat exchange inlet flow channel 121 with the three-way valve cavity 110. That is, by moving the switching mechanism 2 in the three-way valve cavity 110, the passage between the main valve cavity 1101 and the first cavity 1102 or the passage between the main valve cavity 1101 and the second cavity 1103 can be selectively opened, so as to realize three-way switching. The specific structure and working principle of the switching mechanism 2 are not described again in this embodiment, and the switching mechanism that can be applied to the water inlet and outlet valve group to realize three-way switching in the three-way valve cavity in the related art is within the protection scope of this embodiment.

[0060] Further, the water inlet and outlet valve group 100 also includes a driving mechanism (not shown in the figure), and the output end of the driving mechanism is connected with the switching mechanism 2 to drive the switching mechanism 2 to move in the three-way valve cavity 110. In this embodiment, the driving mechanism can adopt a synchronous motor, a stepping motor, a servo motor or other driving devices.

[0061] Figure 6 A second sectional view of the water inlet and outlet valve group 100 provided by this embodiment is shown. To solve the above problems, as shown in the figure, Figure 6 And combined Figure 1 、 Figure 2As shown, the valve body 1 further comprises a bypass valve part 14, two ends of the bypass valve part 14 are connected with the three-way valve part 11 and the water inlet valve part 13 respectively, and a bypass flow channel 141 is arranged in the bypass valve part 14, the bypass flow channel 141 is selectively connected with the heating channel 112 and the second heat exchange outlet channel 134. By arranging the bypass valve part 14, when the main valve cavity 1101 is connected with the heating channel 112, the bypass flow channel 141 is connected with the heating channel 112 and the second heat exchange outlet channel 134, so that the water in the heating channel 112 flows through the bypass flow channel 141 and then flows to the combustion chamber through the second heat exchange outlet channel 134 and the water pump interface 132 in sequence, thereby stabilizing the water pressure balance of the whole wall-mounted stove water system, and further ensuring the safe use of the wall-mounted stove water system. In addition, the water in the heating channel 112 does not need to pass through the heat exchange structure 200 for heat exchange, which can shorten the time required for the combustion chamber to reheat the water, reduce resource loss, and avoid the rapid expansion of the sealing element caused by the heat exchange between the water with high temperature in the heating channel 112 and the water with low temperature in the heat exchange structure 200, thereby ensuring the safety of the wall-mounted stove water system.

[0062] Figure 7 A structure diagram of the one-way assembly 5 is shown. Figure 8 A structure diagram of the one-way assembly 5 is shown. Figures 7-8 And in combination with Figure 6 As shown, the water inlet and outlet valve group 100 further comprises a one-way assembly 5, the one-way assembly 5 comprises a one-way valve 51 and a bypass plug 52, the one-way valve 51 is adjustably installed in the bypass flow channel 141 to allow the water in the heating channel 112 to flow to the water pump interface 132 only; the bypass valve part 14 is provided with a bypass opening connected with the bypass flow channel 141, and the bypass plug 52 is sealed and plugged in the bypass opening. By arranging the one-way valve 51, the water in the water inlet valve part 13 can be prevented from flowing back to the three-way valve part 11, which affects the water quality of the bathroom water; the bypass opening can facilitate the operator to process the bypass flow channel 141 on the bypass valve part 14, thereby simplifying the processing technology and reducing the processing difficulty; the bypass plug 52 can prevent the water in the bypass flow channel 141 from leaking from the bypass opening.

[0063] Specifically, the one-way valve 51 comprises a valve seat 511, a valve core 512 and a spring 513, the valve seat 511 is sealingly installed in the bypass flow channel 141, the valve seat 511 has a valve port 5111 therein, the valve core 512 is movably arranged in the valve seat 511, the spring 513 is connected to the valve seat 511 and the valve core 512 at two ends respectively, and the valve core 512 can block the valve port 5111 under the elastic action of the spring 513. Optionally, the side of the valve core 512 facing the valve port 5111 is further provided with a sealing gasket 514 to improve the good sealing performance of the valve core 512 in the sealing position. Among them, the one-way valve is a commonly used valve structure in the prior art, and the working principle of the one-way valve 51 will not be described in detail in this embodiment.

[0064] In this embodiment, since the bypass valve part 14 is used to connect the three-way valve part 11 and the water inlet valve part 13, the bypass flow channel 141 in the bypass valve part 14 is relatively long, which makes the installation of the one-way valve 51 inconvenient. To solve this problem, in this embodiment, the one-way assembly 5 further comprises a connecting rib 53, and the two ends of the connecting rib 53 are connected to the valve seat 511 and the bypass plug 52 respectively. That is, the operator only needs to hold the bypass plug 52 and insert the one-way valve 51 into the bypass flow channel 141 by aligning the bypass plug 52 with the bypass port, and the installation process is relatively simple and can realize the rapid installation of the one-way valve 51.

[0065] Optionally, the bypass plug 52, the connecting rib 53 and the valve seat 511 are an integral structure, which saves the connecting structure between the bypass plug 52, the connecting rib 53 and the valve seat 511, reduces the number of parts, simplifies the assembly process, is easy to install, and is also conducive to improving the overall strength of the one-way assembly 5. In other embodiments, the bypass plug 52 and the connecting rib 53 and the connecting rib 53 and the valve seat 511 can also be connected by fasteners, which can also achieve the above effects.

[0066] As shown in Figure 7 In this embodiment, the number of connecting ribs 53 is two, and the two connecting ribs 53 are symmetrically arranged on both sides of the bypass plug 52, and the gap between the two connecting ribs 53 can allow water in the bypass flow channel 141 to pass through. This arrangement can improve the stability of the connection between the bypass plug 52 and the valve seat 511 without affecting the water flow in the bypass flow channel 141. Of course, in other embodiments, the number of connecting ribs 53 can also be adjusted according to actual conditions, which is not limited in this embodiment.

[0067] Figure 9 A second view of the water inlet and outlet valve assembly 100 provided by this embodiment is shown. As Figure 9 and in combination with Figure 5As shown, the water inlet valve group 100 further comprises a water flow sensor 3, and the water inlet valve part 13 further has a water inlet channel 130, an inlet of the water inlet channel 130 forms the water inlet interface 131, and the water flow sensor 3 is configured to detect the water flow in the water inlet channel 130, so as to accurately control the water flow, thereby ensuring that the water in the bathroom channel 123 flows out at a suitable temperature and meets the user's water demand.

[0068] In the embodiment, the water flow sensor 3 comprises a magnetic rotor 31 and a Hall element 32, the magnetic rotor 31 is installed in the water inlet channel 130 and can rotate under the impact of the water flow flowing into the water inlet channel 130, and the Hall element 32 is arranged on the water inlet valve part 13 and is signal-connected with the magnetic rotor 31. When the water flow at the water inlet interface 131 flows into the water inlet channel 130, the water flow impacts the magnetic rotor 31 to make it rotate, thereby generating a periodically changing magnetic field, and the Hall element 32 generates a pulse signal by detecting the change of the magnetic field, and the current water flow can be obtained by calculating the pulse frequency, which is simple in structure and can ensure the accuracy of the detection result.

[0069] Figure 10 A third sectional view of the water inlet and outlet valve group 100 provided by the embodiment is shown.
