Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and in particular to a water mixing valve and a water outlet device. Background Art

[0002] The water outlet device on the market usually has a normal temperature water branch and a hot water branch. The normal temperature water branch is equipped with a normal temperature water pump, and the hot water branch is equipped with a hot water pump and heated by a hot tank. The water outlet device controls the power of the normal temperature water pump and the hot water pump, and then controls the ratio of normal temperature water and hot water to achieve control of the outlet water temperature.

[0003] Among them, normal temperature water and hot water will flow into the mixing valve together. The mixing valve usually includes two water inlet pipes, one water inlet pipe is connected to normal temperature water, and the other water inlet pipe is connected to hot water. Normal temperature water and hot water are mixed in the mixing chamber of the mixing valve and flow out through the outlet pipe of the mixing valve. The temperature sensor detects the temperature of the mixed water in the mixing valve, and controls the power of the normal temperature water pump and the hot water pump according to the water temperature data obtained.

[0004] However, the mixing of normal temperature water and hot water in the existing water mixing valve is relatively uneven, resulting in the water temperature in the water mixing valve fluctuating, affecting the accuracy of the control program of the water outlet device. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the utility model, a water mixing valve is provided. The water mixing valve comprises a water outlet pipe, a water mixing part and at least two water inlet pipes, the water outlet pipe and the at least two water inlet pipes are both connected to the water mixing part, at least one of the at least two water inlet pipes is provided with a flow guide, the flow guide has a first side surface facing the water mixing part and a second side surface away from the water mixing part, and the extension direction of at least one of the first side surface and the second side surface forms an angle with the axis of the corresponding water inlet pipe.

[0006] The water mixing valve provided by the present application, through the setting of the guide member, makes the water flow in the corresponding water inlet pipe have a certain degree of offset and rotation relative to the axis of the water inlet pipe. In this way, the water entering the water mixing part can be more fully mixed and flow out from the water outlet pipe. When hot water and normal temperature water are respectively connected to different water inlet pipes of the water mixing valve, the normal temperature water and the hot water are fully mixed in the water mixing part, so that the water temperature in the water mixing valve is more stable. When applied to the water outlet device, the water temperature in the water mixing valve is more stable, and the water outlet device can better control the power of the normal temperature water pump and the hot water pump according to the water temperature data to ensure the accuracy of the outlet water temperature of the water outlet device.

[0007] Exemplarily, the guide member is arranged on the inner wall of the corresponding water inlet pipe. In this way, the guide member is arranged on the inner wall of the corresponding water inlet pipe, that is, the outer periphery of the guide member is connected to the inner wall of the water inlet pipe, and the position of the guide member can be more stable.

[0008] For example, the guide member extends in a spiral shape along the axial direction of the corresponding water inlet pipe. In this way, the water entering the water inlet pipe flows in a spiral shape and enters the water mixing part, the water flows more smoothly, the flow efficiency of the water flows is higher, and the water mixing effect in the water mixing part is better.

[0009] For example, on a predetermined plane perpendicular to the axis of the corresponding water inlet pipe, the projection of the guide member covers the projection of the inner cavity of the corresponding water inlet pipe. In this way, the water flow entering the corresponding water inlet pipe needs to contact the guide member, and the guide member has a better guiding effect.

[0010] For example, the first side surface and the second side surface meet the parallel condition. In this way, the overall thickness of the flow guide member remains unchanged, the structure is simpler, and the flow rate of the water flowing therein can be more stable.

[0011] Exemplarily, the water mixing part has a first end and a second end opposite to each other, at least two water inlet pipes are arranged at the first end, and the water outlet pipe is arranged at the second end. In this way, the water flow can be more fully mixed before flowing into the second end, and the internal space of the water mixing part can be more fully utilized.

[0012] For example, a mixing chamber is formed in the mixing part, and the cross-sectional area of ​​the mixing chamber gradually decreases from the first end to the second end. In this way, the water flowing out of the water inlet pipe needs to pass through the gradually decreasing flow channel together, which can further ensure the mixing degree of the water flow.

[0013] Exemplarily, a temperature sensor is provided on the water mixing part, and the sensing end of the temperature sensor extends into the water mixing chamber. In this way, the water temperature in the water mixing chamber can be known more timely, ensuring the controllability of the water outlet temperature of the water outlet device provided with the water mixing valve.

[0014] Exemplarily, the sensing end is closer to the first end than the second end. In the water mixing chamber, the closer the position is to the first end, the closer it is to the outlet water temperature. The temperature sensor arranged in this way can better measure the outlet water temperature of the water mixing valve.

[0015] Exemplarily, the water mixing part includes a main body and a cover plate disposed on the main body, the main body and the cover plate enclose a water mixing chamber, a mounting boss is disposed on the side of the cover plate away from the water mixing chamber, and the temperature sensor extends into the water mixing chamber through the mounting boss and the cover plate. The provision of the mounting boss makes the installation of the temperature sensor more stable and the overall structure of the water mixing valve is simpler.

[0016] According to another aspect of the utility model, a water outlet device is also provided, which includes a device body and any of the above water mixing valves, wherein the water mixing valve is installed on the device body and the water outlet pipe is connected to the water inlet of the device body.

DETAILED DESCRIPTION

[0031] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0032] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.

[0033] The utility model provides a water mixing valve in the embodiment. Figure 2 , 48, the water mixing valve 100 may include a water outlet pipe 110, a water mixing part 120 and at least two water inlet pipes 130. In the illustrated embodiment, there are two water inlet pipes 130, one of which can be connected to hot water and the other can be connected to normal temperature water. The water outlet pipe 110 and the at least two water inlet pipes 130 are both connected to the water mixing part 120, and at least one of the at least two water inlet pipes 130 is provided with a guide member 1310, and the guide member 1310 has a first side surface 1311 facing the water mixing part 120 and a second side surface 1312 away from the water mixing part 120, and the extension direction of at least one of the first side surface 1311 and the second side surface 1312 has an angle with the axis of the corresponding water inlet pipe 130. It can be understood that the corresponding water inlet pipe 130 is the water inlet pipe 130 provided with the guide member 1310. Take the case where there are two water inlet pipes 130 (hereinafter referred to as the first water inlet pipe 1301 and the second water inlet pipe 1302): when the guide member 1310 is only arranged in the first water inlet pipe 1301, the corresponding water inlet pipe 130 is the first water inlet pipe 1301; when the guide member 1310 is only arranged in the second water inlet pipe 1302, the corresponding water inlet pipe 130 is the second water inlet pipe 1302; when the guide member is arranged in the first water inlet pipe 1301 and the second water inlet pipe 1302, that is, the guide member 1310 also includes a first guide member arranged in the first water inlet pipe 1301 and a second guide member arranged in the second water inlet pipe 1302, when describing the first guide member, the corresponding water inlet pipe 130 is the first water inlet pipe 1301, and when describing the second guide member, the corresponding water inlet pipe 130 is the second water inlet pipe 1302.

[0034] Taking the embodiment in which the extension direction of the first side surface 1311 and the axis of the corresponding water inlet pipe 130 have an angle as an example, when the water flows through the first side surface 1311, the first side surface 1311 can guide the water flow to change the flow direction of the water flow, and the changed flow direction of the water flow has a certain degree of offset and rotation relative to the axial direction. The water flow in the water inlet pipe 130 flows into the mixing part 120 and is mixed and flows out through the water outlet pipe 110. Among them, the water flow flowing out of at least one water inlet pipe 130 has rotation, which can make the water flow in the mixing part 120 better mixed. Similarly, the extension direction of the second side surface 1312 and the axis of the corresponding water inlet pipe 130 have an angle, which can also make the water flow in the mixing part 120 better mixed. Preferably, the extension direction of the first side surface 1311 and the extension direction of the second side surface 1312 can both have an angle with the axis of the corresponding water inlet pipe 130. Among them, the extension direction can be a straight line direction or can extend along a trend. The guide member 1310 can be arranged in one or more of at least two water inlet pipes 130. Preferably, a guide member 1310 can be arranged in each water inlet pipe 130 so that the water flow out of each water inlet pipe 130 can rotate, further improving the degree of mixing of the water flow in the mixing part 120.

[0035] The water mixing valve 100 provided in the present application, through the setting of the guide member 1310, makes the water flow in the corresponding water inlet pipe 130 have a certain degree of offset and rotation relative to the axis of the water inlet pipe 130. In this way, the water entering the water mixing part 120 can be more fully mixed and flow out from the water outlet pipe 110. When hot water and normal temperature water are respectively connected to different water inlet pipes 130 of the water mixing valve 100, the normal temperature water and the hot water are fully mixed in the water mixing part 120, so that the water temperature in the water mixing valve 100 is more stable. When applied to the water outlet device, the water temperature in the water mixing valve 100 is more stable, and the water outlet device can better control the power of the normal temperature water pump and the hot water pump according to the water temperature data to ensure the accuracy of the outlet water temperature of the water outlet device.

[0036] For example, in conjunction with reference Figure 4 and 8 , the guide member 1310 can be arranged on the inner wall of the corresponding water inlet pipe 130. The guide member 1310 can extend from one side of the inner wall to the other side. Exemplarily, there can be a gap between the guide member 1310 and the inner wall of the other side, and the water flows through the gap, and the gap limits the direction of the flow of the water to a certain extent. The flow of the water is further limited by the gap, and the internal space of the water inlet pipe 130 is more fully utilized, and the structure is simpler. In this way, the guide member 1310 is arranged on the inner wall of the corresponding water inlet pipe 130, that is, the outer periphery of the guide member 1310 is connected to the inner wall of the water inlet pipe 130, and the position of the guide member 1310 can be more stable. In other embodiments, the guide member can be arranged in the water inlet pipe in any other structure. For example, a fixed rib can be arranged in the water inlet pipe along the axial direction, and a guide rib is arranged extending outward from the fixed rib, and the outer periphery of the guide rib is always spaced apart from the outer wall of the water inlet pipe.

[0037] For example, continue to combine with reference Figure 4 and 8 , the guide member 1310 can extend in a spiral shape along the axial direction of the corresponding water inlet pipe 130. In this way, the water flow entering the water inlet pipe 130 flows in a spiral shape and enters the water mixing part 120, the water flow flows more smoothly, the flow efficiency of the water flow is higher, and the water mixing effect in the water mixing part 120 is better. In an embodiment not shown, the guide member can be a plurality of protrusions arranged on the inner wall of the corresponding water inlet pipe and spaced apart along the axial direction.

[0038] For example, refer to Figure 4, on a predetermined plane perpendicular to the axis of the corresponding water inlet pipe 130, the projection of the guide member 1310 can cover the projection of the inner cavity of the corresponding water inlet pipe 130. Among them, the projection of the guide member 1310 on the predetermined plane is the projection formed by the guide member 1310 as a whole. It can be understood that, on the cross section of the water inlet pipe 130, there is a gap between the guide member 1310 and the inner wall of the water inlet pipe 130 to facilitate the passage of water, and the projection of the guide member 1310 on the predetermined plane covers the projection of the inner cavity of the corresponding water inlet pipe 130, that is, the gap on each cross section is covered by the guide member 1310 on other cross sections. In this way, the water flow entering the corresponding water inlet pipe 130 needs to contact the guide member 1310, and the guide member 1310 has a better diversion effect. Of course, in other embodiments, on a predetermined plane perpendicular to the axis of the corresponding water inlet pipe, the projection of the guide member may only occupy a portion of the projection of the corresponding water inlet pipe inner cavity. For example, the projection of the guide member may be annular and located within the projection of the water inlet pipe inner cavity.

[0039] For example, refer to Figure 8 , the first side surface 1311 and the second side surface 1312 can meet the parallel condition. In this way, the overall thickness of the flow guide 1310 remains unchanged, and the structure is simpler. The flow rate of the water flowing therein can be more stable. In an embodiment not shown, there can be an angle between the first side surface and the second side surface.

[0040] For example, in conjunction with reference Figure 2 , 3 8, the water mixing part 120 has a first end 1210 and a second end 1220 opposite to each other, at least two water inlet pipes 130 can be arranged at the first end 1210, and the water outlet pipe 110 can be arranged at the second end 1220. That is, the water inlet pipe 130 and the water outlet pipe 110 are respectively located at opposite ends. The water in the water inlet pipe 130 enters the water mixing part 120 from the first end 1210, and flows to the second end 1220, that is, to the water outlet pipe 110 after mixing. In this way, the water flow can be more fully mixed before flowing into the second end 1220, and the internal space of the water mixing part 120 can be more fully utilized.

[0041] Exemplarily, the outer periphery of the end of the water inlet pipe 130 away from the water mixing part 120 may be provided with an undercut structure 1320. Specifically, a pagoda-shaped undercut structure 1320 may be provided to facilitate the connection and fixation of the water inlet pipe 130 with the external silicone pipe to avoid falling off or water leakage.

[0042] For example, in conjunction with reference Figure 7 and 8A mixing chamber 1201 may be formed in the mixing portion 120, and the cross-sectional area of ​​the mixing chamber 1201 may gradually decrease from the first end 1210 to the second end 1220. At least two water inlet pipes 130 and the water outlet pipe 110 are both connected to the mixing chamber 1201. Specifically, the mixing chamber 1201 may be triangular, with the second end 1220 located at one of the corners, and the first end 1210 being the end of the side opposite to the corner. In this way, the water flowing out of the water inlet pipe 130 needs to pass through the gradually decreasing flow channel together, which can further ensure the mixing degree of the water flow. In an embodiment not shown, the cross-sectional area of ​​the mixing chamber may remain unchanged from the first end to the second end.

[0043] For example, in conjunction with reference Figure 2 and 5 The water mixing part 120 is provided with a temperature sensor 140, and the sensing end 1410 of the temperature sensor 140 can extend into the water mixing chamber 1201. The temperature sensor 140 can sense the water temperature in the water mixing chamber 1201. In this way, the water temperature in the water mixing chamber 1201 can be known more timely, ensuring the controllability of the water outlet temperature of the water outlet device provided with the water mixing valve 100.

[0044] For example, in conjunction with reference Figure 3 and 6 , the sensing end 1410 can be closer to the first end 1210 than the second end 1220. In the water mixing chamber 1201, the position closer to the first end 1210 is closer to the outlet water temperature. The temperature sensor 140 arranged in this way can better measure the outlet water temperature of the water mixing valve 100.

[0045] For example, in conjunction with reference Figure 6 and 7 , the water mixing part 120 may include a main body 1230 and a cover plate 1240 disposed on the main body 1230. The main body 1230 and the cover plate 1240 may enclose a water mixing chamber 1201, and a mounting boss 1241 may be disposed on the side of the cover plate 1240 away from the water mixing chamber 1201, and the temperature sensor 140 may extend into the water mixing chamber 1201 through the mounting boss 1241 and the cover plate 1240. An installation cavity may be formed inside the mounting boss 1241, and the temperature sensor 140 may be partially installed in the installation cavity. A sealing ring 1260 may also be disposed between the mounting boss 1241 and the temperature sensor 140. The provision of the mounting boss 1241 makes the installation of the temperature sensor 140 more stable, and the overall structural provision of the water mixing valve 100 is simpler. In an embodiment not shown, the temperature sensor may be disposed at other locations. For example, the temperature sensor may be disposed on the outlet pipe. Exemplarily, the temperature sensor 140 may be connected to the mounting boss 1241 via a fixing member 1250 .

[0046] According to another aspect of the utility model, a water outlet device is also provided. The water outlet device may include a device body 200 and any one of the above-mentioned water mixing valves 100. The water mixing valve 100 is installed on the device body 200 and the water outlet pipe 110 is connected to the water inlet of the device body 200. Since the present water mixing valve 100 adopts the technical solution of any of the above-mentioned embodiments, the water outlet device at least has the beneficial effects brought by the technical solution of the above-mentioned embodiments, which will not be repeated here. In addition, the water outlet device may also include a control component, a heating element 220, etc. The control component and the heating element 220 may have various structures that exist or may appear in the future, which do not constitute a limitation on the protection scope of the utility model. The water outlet device may be a water dispenser, a water purifier, a water heater, etc.

[0047] For example, refer to Fig. 9 , which schematically shows a water circuit diagram of a water outlet device. The water source can be divided into two branches, one branch is connected to a heating element 220 and flows to a water inlet pipe 130 of the mixing valve 100, and the other branch is connected to another water inlet pipe 130 of the mixing valve 100. The two branches can respectively introduce hot water and normal temperature water into the mixing valve 100, and the hot and cold water are mixed and flow out through the mixing valve 100. Exemplarily, the mixing valve 100 can also be connected to a flow meter 210 to monitor the water flow there. A quick-connect plug can be provided at one end of the water outlet pipe 110 away from the mixing part 120 to connect with the quick connector of the flow meter 210.
