DETAILED DESCRIPTION

[0013] The present application describes multiple embodiments, but the description is exemplary rather than restrictive, and it is obvious to those skilled in the art that there may be more embodiments and implementations within the scope of the embodiments described in the present application. Although many possible feature combinations are shown in the drawings and discussed in the specific embodiments, many other combinations of the disclosed features are also possible. Unless specifically limited, any feature or element of any embodiment may be used in combination with any other feature or element in any other embodiment, or may replace any other feature or element in any other embodiment.

[0014] It should be understood that any feature shown and / or discussed in this application can be implemented individually or in any suitable combination. Therefore, except for the limitations made according to the attached claims and their equivalents, the embodiments are not subject to other restrictions. In addition, various modifications and changes can be made within the scope of protection of the attached claims.

[0015] The embodiment of the present application provides a mixing device, which is provided with a mixing chamber connected to a hot water supply unit and a human body cleaning device on a toilet. The mixing device of the present application can be configured to be used only for mixing water, and another independently configured hot water supply unit is provided with a heating chamber. The water heated in the heating chamber has the problem of water temperature stratification and water temperature inconsistency, and then flows into the mixing chamber of the mixing device of the present application so that the water flow is further mixed, and then flows into the human body cleaning device of the toilet for use by the user.

[0016] The mixing chamber of the mixing device of the present application can also be integrated with the heating chamber on the same body, thereby forming a heating device with both the function of heating water and mixing water. Figure 1 To Attachment Fig.18 The schematic diagram of the structure of the heating device of the exemplary embodiment of the present application is shown in FIG. Figure 1 As shown, the heating device of this embodiment is provided with a shell 1, in which a heating chamber 11 and a mixing chamber 12 are provided, a connecting flow path 13 is provided between the mixing chamber 12 and the heating chamber 11, the heating chamber 11 is provided with a first water inlet 111, and the mixing chamber 12 is provided with a first water outlet 121. Water flows into the heating chamber 11 from the first water inlet 111 and is heated, then flows into the mixing chamber 12 through the flow path 13, and finally flows out from the first water outlet 121.

[0017] The following takes the mixing device having only a water mixing function as an example to introduce in detail the structural features and advantages of the mixing chamber of the mixing device of the embodiment of the present application. The embodiment of the present application provides a mixing device, including an outer wall, a mixing chamber is provided in the outer wall, the mixing chamber is connected to a hot water supply unit and a human body cleaning device on a toilet, a connecting flow path is provided between the mixing device and the hot water supply unit, the mixing chamber includes a first chamber and a second chamber, the first chamber is provided with a first connecting port connected to the second chamber, the flow area of ​​at least one first connecting port is smaller than the flow area of ​​the connecting flow path, and the first connecting port is provided at an upper position of the first chamber to split the bubbles entering the first chamber with the water flow and then transport them to the second chamber.

[0018] Specifically, the mixing device of the prior art is provided with a mixing chamber connecting the hot water supply unit and the human body cleaning device on the toilet. The water is heated in the hot water supply unit and enters the mixing chamber to quickly mix and discharge the water flow. In the process of heating the water, the hot water supply unit will gasify part of the water flow to generate bubbles. The bubbles enter the mixing chamber with the water flow. The bubbles mixed in the water flow in the mixing chamber will affect the water temperature mixing consistency of the mixing chamber. The bubbles may gather in the mixing chamber to form large-volume bubbles. The bubbles are discharged from the mixing chamber with the water flow and enter the human body cleaning device. When the large-volume and high-temperature bubbles come into contact with the human body, they will give the user a burning sensation, thereby affecting the user experience.

[0019] The mixing device provided in the embodiment of the present application has a connecting flow path provided between the mixing device and the hot water supply unit, and the mixing chamber includes a first chamber and a second chamber, and the first chamber is provided with a first connecting port connected to the second chamber, and the flow area of ​​the first connecting port is smaller than the flow area of ​​the connecting flow path, and the first connecting port is located at the upper part of the first chamber. Since the density of bubbles is smaller than the density of water, bubbles tend to float up as the water flows, and the bubbles mixed with the water in the first chamber entering the mixing chamber from the hot water supply unit will float to the upper part of the first chamber and flow into the upper part of the side wall of the first chamber or the first connecting port of the top wall of the first chamber. Since the flow area of ​​the first connecting port is smaller than the flow area of ​​the connecting flow path between the mixing chamber and the hot water supply unit, the large bubbles that can flow through the connecting flow path are squeezed and divided and the volume is reduced when passing through the first connecting port, so that the large bubbles mixed in the water flow passing through the first connecting port become small bubbles, so that the volume of the bubbles entering the mixing chamber is reduced, which is conducive to the uniform mixing of the water temperature in the mixing chamber. The volume of bubbles in the mixing chamber is reduced, and the volume of bubbles in the water flow from the mixing chamber to the human body cleaning device on the toilet is smaller. When the tiny bubbles flush the human body with the water flow, the contact area of ​​the tiny bubbles when in contact with the human body is small, and will not cause a high temperature burning sensation, which is beneficial to improving the user experience.

[0020] Moreover, the smaller the flow area of ​​the first connecting port, the faster the water flow speed through the first connecting port, and the fast-flowing water flow can more easily carry away the bubbles, preventing the bubbles from gathering and increasing in volume, so that the bubbles passing through the first connecting port are more strongly impacted by the water flow, accelerating the reduction of the divided volume of the bubbles.

[0021] The technical solution of the mixing device of the present application is now explained with the embodiments shown in the accompanying drawings. For example, Figures 7 to 9 In the embodiment of the mixing device shown in the figure, the hot water supply unit enters the mixing chamber 12 through the connecting flow path 13, and the mixing chamber 12 includes a first chamber 122 and a third chamber 124. The first chamber 122 is connected to the hot water supply unit, and the third chamber 124 is connected to the human body washing device. The first chamber 122 is the first chamber described above, and the third chamber 124 is the second chamber described above. The first chamber 122 and the third chamber 124 are connected through a fourth connecting channel 154. The inlet end of the fourth connecting channel 154 is the first connecting port described above. The first connecting port is located in the first chamber 122. 22, and the flow area of ​​the first connecting port is smaller than the flow area of ​​the connecting flow path 13, so that as the water flows through the large bubbles in the connecting flow path 13, they enter the first chamber 122, the bubbles float up in the first chamber 122 and enter the fourth connecting channel 154 located at the upper part of the first chamber 122, and when passing through the inlet end of the fourth connecting channel 154 with a smaller flow area, the large bubbles are squeezed and divided and their volume is reduced, so that the volume of the bubbles mixed in the water entering the third chamber 124 from the fourth connecting channel 154 is reduced, so that the volume of the bubbles in the mixing chamber 12 is reduced.

[0022] For example, Figures 7 to 9 In the embodiment of the mixing device shown, the hot water supply unit enters the mixing chamber 12 through the connecting flow path 13, and the mixing chamber 12 includes a second chamber 123 and a third chamber 124. The second chamber 123 is a sub-chamber located in the middle of all sub-chambers, and the third chamber 124 is a sub-chamber directly connected to the human body washing device. The second chamber 123 is the above-mentioned first chamber, and the third chamber 124 is the above-mentioned second chamber. The second chamber 123 and the third chamber 124 are connected through a third connecting channel 153, and the inlet end of the third connecting channel 153 is the above-mentioned first connecting port. The flow area at the inlet end of the third connecting channel 153 is smaller than the flow area of ​​the connecting flow path. As the water flows through the large bubbles in the connecting flow path 13, they enter the second chamber 123. The bubbles float up in the second chamber 123 and enter the third connecting channel 153 located at the upper part of the second chamber 123. When passing through the inlet end of the third connecting channel 153 with a smaller flow area, the large bubbles are squeezed and divided and their volume is reduced. In this way, the volume of the bubbles mixed in the water entering the third chamber 124 from the third connecting channel 153 is reduced, so that the volume of the bubbles in the mixing chamber 12 is reduced.

[0023] In the embodiment of the present application, an upstream sub-chamber is connected to a downstream sub-chamber, and the inlet end of the water channel connecting the two sub-chambers is located at the upper part of the upstream sub-chamber, and the flow area of ​​the inlet end of the water channel is smaller than the flow area of ​​the connecting flow path, so that when the bubbles mixed in the water of the upstream sub-chamber enter the inlet end of the connecting flow path, they can be squeezed and divided and the volume is reduced, so that the volume of the bubbles in the water entering the downstream sub-chamber becomes smaller. The volume of the bubbles in the mixing chamber is reduced, and the volume of the bubbles in the water flow flowing from the mixing chamber into the human body cleaning device of the toilet is smaller. When the tiny bubbles are flushed with the water flow, the contact area of ​​the tiny bubbles when they contact the human body is smaller, which will not cause a high temperature burning sensation, which is conducive to improving the user experience.

[0024] It is understood that the number of sub-chambers of the mixing chamber of the mixing device of the present application is not limited to Figures 7 to 9 The three sub-chambers shown in the embodiment may be two, four or more sub-chambers. The first chamber and the second chamber are not limited to the sub-chambers directly connected to the hot water supply unit or the human body cleaning device. The number of the first connecting ports may be multiple, all within the protection scope of the present application.

[0025] In an exemplary embodiment, the first chamber is a head chamber directly connected to a hot water supply unit, and the second chamber is a terminal chamber directly connected to a human body washing device, and the head chamber is connected to the terminal chamber through at least two water channels; the at least two water channels include a first water channel and a second water channel, the first water channel has a first connecting port, the second water channel has a second connecting port, and the second connecting port is arranged in the first chamber.

[0026] Specifically, when the head end chamber is connected with the terminal chamber through multiple water channels, the water entering the mixing chamber from the hot water supply unit is divided into water flowing along multiple water channels in the mixing chamber and finally converges in the terminal chamber. There are multiple streams of water flowing and converging in the terminal chamber, the water flows in the terminal chamber collide violently, the water temperature is mixed more evenly, and the bubbles mixed in the water flow are easily broken up and reduced in volume.

[0027] Instructions attached Figures 7 to 9 The embodiment of the mixing device shown explains the technical solution of the present application. Figures 7 to 9As shown, the first chamber 122 is the head chamber, and the third chamber 124 is the end chamber. The first chamber 122 is directly connected to the hot water supply unit through the connecting flow path 13, and the third chamber 124 is directly connected to the human body washing device. There are multiple water channels between the first chamber 122 and the third chamber 124, specifically including: the fourth connecting channel 154, the first connecting channel 151 through the second chamber 123 and then through the third connecting channel 153, and the second connecting channel 152 through the second chamber 123 and then through the third connecting channel 153. The fourth connecting channel 154 is the above-mentioned first water channel, the first connecting channel 151 through the second chamber 123 and then through the third connecting channel 153 is the above-mentioned second water channel, the inlet end of the fourth connecting channel 154 is the above-mentioned first connecting port, and the inlet end of the second water channel is the inlet end of the first connecting channel 151, that is, the above-mentioned second connecting port. The above-mentioned first connecting port and second connecting port are both arranged on the cavity wall of the first chamber 122. The inlet end of the fourth communication channel 154 is located at the upper portion of the first chamber 122 , and the flow area of ​​the inlet end of the fourth communication channel 154 is smaller than the flow area of ​​the communication flow path 13 .

[0028] For example, Figures 7 to 9 As shown, the first chamber 122 is the head chamber, and the third chamber 124 is the end chamber. The first chamber 122 is directly connected to the hot water supply unit through the connecting flow path 13, and the third chamber 124 is directly connected to the human body washing device. There are multiple water channels between the first chamber 122 and the third chamber 124, specifically including: the fourth connecting channel 154, the first connecting channel 151 through the second chamber 123 and then through the third connecting channel 153, and the second connecting channel 152 through the second chamber 123 and then through the third connecting channel 153. The first connecting channel 151 through the second chamber 123 and then through the third connecting channel 153 is the above-mentioned first water channel, and the second connecting channel 152 through the second chamber 123 and then through the third connecting channel 153 is the above-mentioned second water channel. The inlet end of the first connecting channel 151 of the first water channel is the above-mentioned first connecting port, and the inlet end of the second connecting channel 152 of the second water channel is the above-mentioned second connecting port. The first and second communication ports are both disposed on the cavity wall of the first cavity 122 , and the inlet end of the first communication channel 151 is located at the upper portion of the first cavity 122 . The flow area of ​​the first communication channel 151 is smaller than the flow area of ​​the communication flow path 13 .

[0029] It can be understood that the head end chamber and the tail end chamber of the embodiment of the present application can be connected by three or more water channels, not limited to two water channels; the sub-chambers of the mixing chamber of the embodiment of the present application are not limited to three, and can be two, four or more sub-chambers, all within the protection scope of the present application.

[0030] In an exemplary embodiment, the first communication port is located higher than the second communication port.

[0031] Specifically, the first connecting port is located higher than the second connecting port, and the density of bubbles is lower than that of water, so the bubbles in the water of the upstream sub-chamber tend to float to the upper part of the upstream sub-chamber, and then the bubbles will preferentially enter the downstream sub-chamber through the first connecting port located at a high position, which is conducive to the bubbles in the water of the upstream sub-chamber to flow into the downstream sub-chamber faster. The high-temperature water in the upstream sub-chamber has a tendency to float and preferentially enters the downstream sub-chamber through the first connecting port located at a high position, while the low-temperature water in the upstream sub-chamber has a tendency to sink and preferentially enters the downstream sub-chamber through the second connecting port located at a low position. The downstream sub-chamber has a high-temperature multi-layer water flow collision and mixing situation, which is also conducive to more uniform water temperature mixing in the mixing chamber.

[0032] by Figures 7 to 9 The embodiment of the heating device shown in the figure is used as an example to explain the technical solution of the present application. For example, the first chamber 122 is the head end chamber, the third chamber 124 is the end chamber, the first chamber 122 is directly connected to the hot water supply unit through the connecting flow path 13, and the third chamber 124 is directly connected to the human body washing device. The first connecting channel 151 is the above-mentioned first water channel via the second chamber 123 and then via the third connecting channel 153, and the second connecting channel 152 is the above-mentioned second water channel via the second chamber 123 and then via the third connecting channel 153. The position of the inlet end of the first connecting channel 151 of the first water channel is higher than the position of the inlet end of the second connecting channel 152 of the second water channel. The inlet end of the first connecting channel 151 is set as the above-mentioned first connecting port, and the inlet end of the second connecting channel 152 is set as the above-mentioned second connecting port, and the first connecting port is higher than the second connecting port. The bubbles mixed in the water in the first chamber 122 float to the upper part of the first chamber 122, and will preferentially enter the second chamber 123 on the downstream side through the first connecting channel 151. The high-temperature water in the first chamber 122 will preferentially enter the second chamber 123 through the first connecting channel 151 located at a high position, while the low-temperature water in the first chamber 122 will preferentially enter the second chamber 123 through the second connecting channel 152 located at a low position. There is a situation in which two layers of high and low temperature water flows collide and mix in the second chamber 123, and the water temperature in the second chamber 123 is mixed more evenly.

[0033] For another example, Figures 7 to 9As shown, the first chamber 122 is the head chamber, the third chamber 124 is the end chamber, the fourth connecting channel 154 is the first water channel mentioned above, and the second connecting channel 152 is the second water channel mentioned above via the second chamber 123 and then the third connecting channel 153. The inlet end of the fourth connecting channel 154 of the first water channel is higher than the inlet end of the second connecting channel 152 of the second water channel. The inlet end of the fourth connecting channel 154 is set as the first connecting port mentioned above, and the inlet end of the second connecting channel 152 is set as the second connecting port mentioned above, and the first connecting port is higher than the second connecting port. The bubbles mixed in the water in the first chamber 122 float to the upper part of the first chamber 122 and will preferentially enter the end chamber through the fourth connecting channel 154. The high-temperature water in the first chamber 122 will also enter the third chamber 124 through the fourth connecting channel 154, while the low-temperature water in the first chamber 122 will preferentially enter the third chamber 124 through the second connecting channel 152 and then through the second chamber 123. In this way, there are multiple water flows with different water temperatures colliding and mixing in the third chamber 124, and the water temperature in the third chamber 124 is mixed more evenly.

[0034] In an exemplary embodiment, a flow area of ​​the second communication port is greater than a flow area of ​​the first communication port.

[0035] Specifically, the position of the first communication port is higher than that of the second communication port, the flow area of ​​the second communication port is larger than that of the first communication port, the density of bubbles is lower than that of water, and after the bubbles float to the upper part of the water, they pass through the first communication port with a smaller flow area located at a higher position, and the large bubbles will be divided and squeezed to reduce their volume. In addition, the small flow area of ​​the first communication port means a fast flow rate, which is conducive to the rapid flow of bubbles and the breaking up of bubbles with the water flow to reduce their volume. After the low-temperature water sinks to the lower part, it passes through the second communication port with a larger flow area located at a lower position, which is conducive to a large amount of low-temperature water flowing into the downstream sub-chamber.

[0036] Instructions attached Figures 7 to 9The technical solution of the present application is explained as an example. In one embodiment, the first chamber 122 is the head chamber, the second chamber 123 is the end chamber, and the first chamber 122 and the second chamber 123 are connected by two water channels, the first connecting channel 151 and the second connecting channel 152. The inlet end of the first connecting channel 151 is the first connecting port of the present application, and the inlet end of the second connecting channel 152 is the second connecting port of the present application. The inlet end of the first connecting channel 151 is higher than the inlet end of the second connecting channel 152, and the flow area of ​​the inlet end of the first connecting channel 151 is smaller than the flow area of ​​the inlet end of the second connecting channel 152. Therefore, the bubbles in the water of the first chamber 122 will be squeezed and divided into small bubbles and enter the second chamber 123 preferentially through the first connecting channel 151 with a smaller flow area. The high-temperature water in the first chamber 122 enters the second chamber 123 through the first connecting channel 151, and a large amount of low-temperature water in the first chamber 122 will enter the second chamber 123 through the second connecting channel 152 with a larger flow area, which is conducive to a large amount of low-temperature water in the first chamber 122 flowing into the downstream sub-chamber for water temperature mixing.

[0037] For another example, the first chamber 122 is the head chamber, the third chamber 124 is the end chamber, the fourth communication channel 154 is the first waterway channel, the inlet end of the fourth communication channel 154 is the first communication port of the present application, the second communication channel 152 passes through the second chamber 123 and then through the third communication channel 153 to become the second waterway channel, the inlet end of the second communication channel 152 is the second communication port of the present application, the inlet end of the fourth communication channel 154 is higher than the inlet end of the second communication channel 152, and the flow area of ​​the inlet end of the fourth communication channel 154 is smaller than the flow area of ​​the inlet end of the second communication channel 152. Therefore, the bubbles in the water of the first chamber 122 will be squeezed and divided into small bubbles and enter the third chamber 124 preferentially through the fourth communication channel 154 with a smaller flow area located at a high position, and the low-temperature water of the first chamber 122 will preferentially enter the second chamber 123 and then enter the third chamber 124 through the second communication channel 152.

[0038] It is understood that the sub-chambers of the mixing chamber of the embodiment of the present application are not limited to Figures 7 to 9 The three sub-chambers shown in the figure are not limited to the water channels of the present application. Figures 7 to 9 The three specific waterway channels are shown, and other embodiments that conform to the technical solution of this application are also within the protection scope of this application.

[0039] In an exemplary embodiment, the head end chamber and the tail end chamber have a common chamber wall, and the first communication port is located on the common chamber wall.

[0040] The first communication port is located on the common cavity wall of the head end cavity and the tail end cavity, and the first communication port is located at the upper part of the head end cavity. Since the first communication port is located at the upper part of the first cavity, the bubbles mixed in the water of the first cavity will preferentially enter the tail end cavity through the first communication port, which is conducive to the rapid discharge of the bubbles in the mixing cavity and avoids the bubbles in the water of the mixing cavity from frequently flowing between multiple sub-cavities. In addition, the bubbles stay in the mixing cavity for a short time, and the bubbles will not gather in the mixing cavity and increase in volume.

[0041] by Figures 7 to 9 The embodiment shown in the figure is used as an example to explain the technical solution of the present application. The first cavity 122 is the head end cavity mentioned above, and the third cavity 124 is the end cavity mentioned above. There is a common cavity wall between the first cavity 122 and the third cavity 124. Figure 8 The first plate 31 in the first chamber 122 is connected to the third chamber 124 by the fourth connecting channel 154, and the inlet end of the fourth connecting channel 154 is located on the common chamber wall, i.e., the first plate 31. The inlet end of the fourth connecting channel 154 is the first connecting port mentioned above. In this way, the bubbles mixed in the water of the first chamber 122 preferentially enter the third chamber 124 through the fourth connecting channel 154, which is conducive to the rapid discharge of the bubbles in the mixing chamber out of the mixing chamber.

[0042] It can be understood that the mixing chamber of the embodiment of the present application can be two sub-chambers, and the two sub-chambers are the head end chamber and the end chamber. The mixing chamber of the embodiment of the present application can be three or more sub-chambers, the head end chamber and the end chamber have a common cavity wall, and the bubbles in the head end chamber can flow directly and quickly into the end chamber. The above embodiments are all within the protection scope of the present application.

[0043] In an exemplary embodiment, the mixing chamber is provided with at least three sub-chambers including a first chamber and a second chamber, the second water channel flows through the other sub-chambers except the first chamber and the second chamber, and the second communication port is located lower than the first communication port.

[0044] Specifically, the first chamber is the head chamber, the second chamber is the end chamber, the first water channel directly connects the head chamber and the end chamber, and the second water channel enters the end chamber from the head chamber through other sub-chambers. Since the first connecting port is located higher than the second connecting port, the bubbles in the water of the head chamber will preferentially enter the end chamber directly through the first connecting port located at a higher position, which is conducive to the rapid discharge of bubbles in the mixing chamber.

[0045] For example, the instruction manual Figures 7 to 9The middle mixing chamber includes three sub-chambers, the head end chamber is the first chamber 122, the end chamber is the third chamber 124, the second chamber 123 is the other sub-chambers, the first waterway channel is the fourth connecting channel 154, and the second waterway channel is a plurality of waterway channels from the first chamber 122 through the other sub-chambers, namely the second chamber 123, and then into the third chamber 124.

[0046] It is understood that the embodiments of the present application are not limited to Figures 7 to 9 The specific structure shown.

[0047] In an exemplary embodiment, the mixing chamber is provided with at least three sub-chambers including a first chamber and a second chamber; a sub-chamber is provided between the head end chamber and the tail end chamber, and the first water channel flows through the sub-chamber.

[0048] Specifically, the mixing chamber of the embodiment of the present application includes three or more sub-chambers, the first water channel flows through the head end chamber and then enters the other sub-chambers and finally enters the end chamber, so that the water in the head end chamber enters the first water channel and passes through multiple sub-chambers before entering the end chamber. The first water channel flows through multiple sub-chambers, and the water in the first water channel is mixed more evenly and fully. At the same time, this approach can expand the types and application scope of the mixing device of the embodiment of the present application.

[0049] In an exemplary embodiment, Figure 2 , Figures 5 to 9 As shown, a splitter plate 3 is provided in the mixing chamber 12, and the splitter plate 12 divides the mixing chamber 12 into a plurality of sub-chambers, and the splitter plate 3 and the outer wall are both separate structures.

[0050] Specifically, Figure 2 As shown, the splitter plate 3 and the outer wall of the mixing chamber 12 are separated structures, and the splitter plate 3 is inserted into the mixing chamber 12 to divide the mixing chamber 12 into a plurality of sub-chambers. This method is conducive to the manufacture and assembly of the splitter plate 3 and the outer wall of the mixing chamber 12.

[0051] It is understandable that the splitter plate 3 and the outer wall of the mixing chamber 12 may also be integrally formed, which is within the protection scope of the present application.

[0052] In an exemplary embodiment, Figure 7 and Fig. 9 As shown, the first communication port and / or the second communication port is located at the connection position between the diverter plate 3 and the outer wall.

[0053] Specifically, Figure 7 and Fig. 9As shown, one of the inlet end of the fourth communication channel 154, the inlet end of the first communication channel 151, and the inlet end of the second communication channel 152 is the first communication port or the second communication port. The inlet end of the fourth communication channel 154, the inlet end of the first communication channel 151, and the inlet end of the second communication channel 152 are all located at the connection position between the diverter plate 3 and the outer wall. In this way, the first communication port or the second communication port can be formed by machining a groove on the outer surface of the diverter plate 3 or the outer wall. This method simplifies the processing technology of the mixing device.

[0054] In an exemplary embodiment, the first communication port and / or the second communication port is located on the diverter plate.

[0055] Specifically, the first connecting port and / or the second connecting port is located on the diverter plate, and the first connecting port or the second connecting port is processed inside the wall of the diverter plate. This approach can expand the types of mixing chambers in the embodiments of the present application. By changing the position of the first connecting port or the second connecting port in the mixing chamber, the specific path of the water channel can be changed, and the bubble exhaust effect of the mixing chamber can be adjusted.

[0056] In an exemplary embodiment, Figure 3 and Figure 7 As shown, the outer wall is provided with a first opening, and the splitter plate 3 is configured to be placed into the mixing chamber 12 through the first opening.

[0057] Specifically, Figure 3 and Figure 7 In the embodiment of the mixing chamber 12 and the outer wall shown, the outer wall is provided with a first opening, so that the splitter plate 3 can be inserted into the mixing chamber 12 through the first opening. This approach facilitates the assembly and disassembly operations of the mixing device.

[0058] In an exemplary embodiment, the mixing chamber is provided with a plurality of sub-chambers, including two sub-chambers sharing a common chamber wall, the chamber wall is provided with a plurality of connecting ports connecting the two sub-chambers, and along the water flow direction of the plurality of connecting ports, the extension direction of the plurality of connecting ports tends to converge.

[0059] Specifically, along the direction of water flow, multiple connecting ports connecting two adjacent sub-chambers along the direction of water flow tend to converge, so that the water in the upstream sub-chamber is divided into multiple streams by the multiple connecting ports. When the multiple streams of water flow into the sub-chamber located on the downstream side of the water flow of the multiple connecting ports, the multiple streams of water converge and collide violently, the flow velocity increases, and the bubbles mixed in the water flow are also violently impacted and collided, and the volume of the bubbles is reduced.

[0060] For example, in Figures 7 to 9 In the embodiment shown, the second chamber 123 and the third chamber 124 are connected through the third connecting passage 153. Figure 8The third communication channel 153 is divided into two sub-communication ports, which are directed from the second cavity 123 to the third cavity 124, and the extension directions of the multiple sub-communication ports tend to converge. In this way, the water flow in the second cavity 123 is divided into two streams and enters the third cavity 124. The two streams entering the third cavity 124 converge and collide violently, and the flow rate in the third cavity 124 increases, so that the bubbles mixed in the water entering the third cavity 124 through the third communication channel 153 accelerate the collision and break up, and the volume of the bubbles decreases.

[0061] In an exemplary embodiment, Figures 7 to 9 As shown, the mixing chamber 12 of an embodiment of the present application includes three sub-chambers, which are connected together through a connecting port. The three sub-chambers include a first chamber 122, a second chamber 123 and a third chamber 124. The first chamber 122 is directly connected to the hot water supply unit, and the third chamber 124 is directly connected to the human body washing device. The mixing chamber 12 is provided with a first water outlet 121 for water to discharge from the mixing chamber 12, and the third chamber 124 is provided with a first water outlet 121; the connecting port 15 includes a first connecting channel 151, a second connecting channel 152, a third connecting channel 153 and a fourth connecting channel 154.

[0062] The first cavity 122 is connected to the second cavity 123 through the first communication channel 151 and the second communication channel 152 , the second cavity 123 is connected to the third cavity 124 through the third communication channel 153 ; the first cavity 122 is connected to the third cavity 124 through the fourth communication channel 154 .

[0063] Among them, Figure 7 As shown, the height of the fourth communication channel 154 is higher than the heights of the first communication channel 151 and the second communication channel 152; Figure 7 and Fig. 9 As shown, the flow area of ​​the first communication channel 151 is smaller than the flow area of ​​the second communication channel 152, and the height of the first communication channel 151 is higher than the height of the second communication channel 152. Figure 8 As shown, there are multiple third communication channels 153 , and along the direction from the second cavity 123 to the third cavity 124 , the central axes of the multiple third communication channels 153 extend obliquely toward each other.

[0064] Specifically, Fig. 9 The arrows in the figure indicate the flow direction of the water in the mixing chamber 12 in each sub-chamber. Fig. 9The circles in the figure represent bubbles in each sub-chamber. The bubbles in the third chamber 124 are small in volume, while the bubbles in the first chamber 122 are large in volume. In the mixing device of the embodiment of the present application, the fourth connecting channel 154 is located higher than the first connecting channel 151 and the second connecting channel 152, so that most of the bubbles mixed in the water flow entering the first chamber 122 can smoothly pass through the fourth connecting channel 154 to enter the third chamber 124 at the downstream end and be discharged from the mixing chamber 12 after floating to the upper position of the first chamber 122, thereby preventing the bubbles mixed in the water flow of the first chamber 122 from passing through the first connecting channel 151 and the second connecting channel 152 to enter the second chamber 123 in the middle of the water flow path of the mixing chamber 12. This structural design is conducive to most of the bubbles in the first chamber 122 quickly entering the third chamber 124 and being discharged from the mixing chamber 12.

[0065] In the mixing device of the embodiment of the present application, the flow area of ​​the first connecting channel 151 is smaller than the flow area of ​​the second connecting channel 152, and the height of the first connecting channel 151 is higher than the height of the second connecting channel 152. The low-temperature water flows downward, and the high-temperature water flows upward. The bubbles, which have a lower density than water, also float upward, so that most of the low-temperature water in the first chamber 122 enters the second chamber 123 through the second connecting channel 152 with a larger flow area, and a small amount of high-temperature water carries a small amount of bubbles through the first connecting channel 151 with a smaller flow area and enters the second chamber 123. The flow area of ​​the first connecting channel 151 is small, so the flow rate of water passing through the first connecting channel 151 is fast, which is conducive to the bubbles mixed in the water flow passing through the first connecting channel 151 being squeezed and divided to form bubbles with smaller volumes, so that the bubbles entering the second chamber 123 are smaller in volume and are easily discharged from the second chamber 123.

[0066] It can be understood that the first connecting channel 151 is higher than the second connecting channel 152, and the low-temperature water flows downward, while the high-temperature water flows upward, so that the low-temperature water in the first chamber 122 enters the second chamber 123 through the second connecting channel 152, and the high-temperature water in the first chamber 122 enters the second chamber 123 through the first connecting channel 151, so that the water in the second chamber 123 flows in layers with different water temperatures and the water temperature mixing is more uniform.

[0067] In the mixing device of the embodiment of the present application, there are multiple third connecting channels 153, and the multiple third connecting channels 153 tend to converge near one end of the third chamber 124, so that after the water flows through the third connecting channels 153 and enters the third chamber 124, the mixing and collision are more intense, so that the bubbles mixed in the multiple water flows flowing out of the multiple third connecting channels 153 can accelerate the impact and collision and reduce their volume, thereby reducing the volume of the bubbles entering the third chamber 124, which is beneficial to the discharge of the bubbles in the mixing chamber 12.

[0068] In an exemplary embodiment, Figure 7As shown, the third communication channel 153 is located higher than the first communication channel 151 .

[0069] Specifically, the third communication channel 153 is higher than the first communication channel 151, so that the bubbles mixed with the water flow in the second chamber 123 float to the upper position of the second chamber 123 and smoothly pass through the third communication channel 153 into the third chamber 124. It can be understood that the position of the third communication channel 153 is higher than the first communication channel 151, which is also conducive to the high-temperature part of the water flow mixed in the second chamber 123 entering the third chamber 124 through the third communication channel 153.

[0070] In an exemplary embodiment, Figure 4 As shown, the bottom wall of the mixing chamber 12 includes a protrusion 125 protruding toward the inside of the mixing chamber 12. Figure 5 and Figure 6 As shown, the splitter plate 3 includes a first plate 31 and a second plate 32 connected to each other. Figure 7 and Figure 8 As shown, the first plate 31 is configured to extend along the length direction of the protrusion 125, and the lower end of the first plate 31 is connected to the top of the protrusion 125, and the upper end of the first plate 31 is connected to the top wall of the mixing chamber 12, so that the space on one side of the width direction of the protrusion 125 forms a third chamber 124.

[0071] like Figure 7 , Figure 8 and Fig. 9 As shown, the second plate 32 is located on one side of the first plate 31 and is connected to the middle of the side wall of the first plate 31, and the lower end of the second plate 32 is connected to the side wall of the protrusion 125 and the bottom wall of the mixing chamber 12, and the upper end of the second plate 32 is connected to the top wall of the mixing chamber 12, so that the space on the other side of the protrusion 125 in the width direction forms the first chamber 122 and the second chamber 123.

[0072] Specifically, a ridge 125 is provided on the bottom wall of the mixing chamber 12, the first plate 31 of the diverter plate 3 is connected to the top of the ridge 125, and the second plate 32 of the diverter plate 3 is connected to the ridge 125 and the bottom wall of the mixing chamber 12, so that the mixing chamber 12 is divided into a first chamber 122, a second chamber 123 and a third chamber 124. The structure is simple in design and easy to process and assemble. When the water in the first chamber 122 and the second chamber 123 flows toward the top of the ridge 125, the flow area of ​​the water flow is reduced and the flow rate of the water flow is increased. Therefore, when the water in the first chamber 122 enters the third chamber 124 through the fourth connecting channel 154, and when the water in the second chamber 123 enters the third chamber 124 through the third connecting channel 153, the flow rate will increase, which is conducive to the bubbles being washed into small bubbles along with the fast-flowing water flow, thereby facilitating the discharge of bubbles from the mixing chamber 12.

[0073] The external shape and structure of the flow divider 3 in the mixing device of the present application is not limited to that in the appendix of the specification. Figure 5 and Figure 6 The T-shape shown may also be other shapes, as long as the diverter plate 3 can divide the mixing chamber 12 into a plurality of sub-chambers, all of which are within the protection scope of the present application.

[0074] In an exemplary embodiment, Figure 7 As shown, the first connecting channel 151 is arranged at the connection between the second plate 32 and the raised portion 125, the second connecting channel 152 is arranged between the lower end of the second plate 32 and the bottom wall of the mixing chamber 12, and the fourth connecting channel 154 and the third connecting channel 153 are arranged at the connection between the first plate 31 and the raised portion 125.

[0075] Specifically, Figure 6 As shown, the diverter plate 3 is provided with a first connecting groove 33, a second connecting groove 34, an exhaust groove 36, and a third connecting groove 35. The exhaust groove 36 and the top wall of the raised portion 125 enclose a fourth connecting channel 154. The first connecting groove 33 and the side wall of the raised portion 125 enclose a first connecting channel 151. The second connecting groove 34 and the bottom wall of the mixing chamber 12 enclose a second connecting channel 152. The third connecting groove 35 and the top wall of the raised portion 125 enclose a third connecting channel 153. A plurality of grooves are arranged on the bottom outer surface of the diverter plate 3, and the bottom wall of the mixing chamber 12 and the raised portion 125 enclose a connecting port. The grooves on the bottom outer surface of the diverter plate 3 are easy to process and shape, and the size of the grooves can be modified according to user needs.

[0076] The following is a detailed introduction Fig. 9 The water flow path and bubble flow of the mixing device of one embodiment of the present application are shown. Fig. 9The arrow in the figure indicates the direction of water flow in the mixing chamber 12, and the circle represents bubbles. The water flow path of the mixing device of the embodiment of the present application is as follows: the water flows into the first chamber 122, most of the bubbles in the water of the first chamber 122 float to the upper part of the first chamber 122, the high-temperature part of the water flow in the first chamber 122 enters the third chamber 124 through the fourth connecting channel 154, and the bubbles located at the upper part of the first chamber 122 follow the water flow through the fourth connecting channel 154 and enter the third chamber 124. The low-temperature water flow of the first chamber 122 enters the second chamber 123 through the second connecting channel 152, and a part of the high-temperature water flow and a small amount of bubbles in the first chamber 122 enter the second chamber 123 through the first connecting channel 151. The low-temperature water flow and the high-temperature water flow entering the second chamber 123 flow in layers and mix together, and then enter the third chamber 124 through the third connecting channel 153. The bubbles in the second chamber 123 float to the upper part of the second chamber 123 and enter the third chamber 124 through the third connecting channel 153. The bubbles entering the third chamber 124 are further reduced in volume under the mixed impact of the multiple water flows and float to the upper part of the third chamber 124 , and finally discharged from the mixing chamber 12 .

[0077] The present application embodiment provides a heating device, such as Figure 2 and Fig. 9 As shown, it includes a hot water supply unit and a mixing device as described in any one of the above exemplary embodiments, the hot water supply unit includes a shell 1 and a heating element 2, the shell 1 is provided with a heating chamber 11, the heating element 2 is arranged in the heating chamber 11, the heating element 2 is used to heat the water in the heating chamber 11, and the heating chamber 11 is connected to the mixing chamber 12 of the mixing device.

[0078] Specifically, the heating chamber 11 of the hot water supply unit and the mixing chamber 12 of the mixing device of the embodiment of the present application can be integrated on the same body, such as Figure 2 and Fig. 9 In the embodiment shown, the heating chamber 11 and the mixing chamber 12 are integrated in one body. The heating chamber 11 of the hot water supply unit and the mixing chamber 12 of the mixing device of the embodiment of the present application can be distributed on different bodies to form two independent devices. All of them are within the protection scope of the present application.

[0079] The heating device of the embodiment of the present application includes the mixing device of the above exemplary embodiment, and therefore has the structural features and advantages of the mixing device of the above exemplary embodiment, which will not be described in detail here.

[0080] The heating element 2 is used to heat the water in the heating chamber 11. Part of the water in the heating chamber 11 will vaporize to form bubbles. The water temperature in the heating chamber 11 is uneven and there is a stratification phenomenon in the water temperature in the heating chamber 11. The bubbles in the heating chamber 11 flow out of the heating chamber 11 along with the water and enter the mixing chamber 12. The mixing chamber 12 can make the water temperature mix more uniformly, and the mixing chamber 12 of the embodiment of the present application can reduce the volume of the bubbles, thereby improving the user experience.

[0081] In an exemplary embodiment, Figure 2 , Figure 3 , Figure 7 and Fig. 9 As shown, the housing 1 and the outer wall of the mixing device are formed in one piece.

[0082] Specifically, the shell 1 and the outer wall of the mixing device are integrally formed, so that the heating device integrates the functions of heating water and mixing water. This approach can simplify the structural design of the heating device and reduce the space occupied by the equipment.

[0083] In an exemplary embodiment, Figure 4 , Figure 7 and Fig.14 As shown, the housing 1 comprises a second opening, the heating element 2 is placed into the heating chamber 11 via the second opening, and the first opening and the second opening are oriented in the same direction.

[0084] Specifically, the housing 1 is provided with a second opening, which facilitates the assembly and disassembly of the heating element 2. The first opening and the second opening are oriented in the same direction, such as Figure 2-Figure 4 As shown, a mounting seat 6 is provided to block the first opening and the second opening at the same time.

[0085] An embodiment of the heating device shown in the accompanying drawings will now be described in detail, which has the functions of heating water and mixing water. Figure 1-Figure 3 This is a schematic diagram of the structure of a heating device according to an embodiment of the present application. Fig.14 This is a schematic diagram of the assembly of the heating device of this embodiment. Fig.14 The arrows in the middle indicate the assembly movement direction of each component. Fig.17 This is a schematic diagram of the exploded structure of a heating device according to another embodiment of the present application. The heating device provided in the embodiment of the present application includes a housing 1 and a heating element 2. The housing 1 is provided with a heating chamber 11 and a mixing chamber 12, a connecting flow path 13 is provided between the heating chamber 11 and the mixing chamber 12, the heating chamber 11 is provided with a first water inlet 111, and the mixing chamber 12 is provided with a first water outlet 121. The heating element 2 is provided in the heating chamber 11, and is used to heat and raise the temperature of the water in the heating chamber 11. The mixing chamber 12 is the mixing chamber 12 of the mixing device described in any one of the above exemplary embodiments.

[0086] Specifically, the heating device provided in the embodiment of the present application has the functions of heating water and mixing water. The housing 1 is provided with a connected heating chamber 11 and a mixing chamber 12. The heating chamber 11 is used to heat water, and the mixing chamber 12 makes the water temperature mix more uniformly. After the water enters the heating chamber 11 from the first water inlet 111 and is heated by the heating element 2, it enters the mixing chamber 12 through the circulation flow path 13. The water temperature is mixed more uniformly in the mixing chamber 12, and finally discharged from the first water outlet 121.

[0087] In an exemplary embodiment, Figure 7 As shown, the heating chamber 11 is provided with a drainage port 112 connected to the input end of the connecting flow path 13, and the drainage port 112 is located at the upper part of the heating chamber 11; the first water outlet 121 is provided at the upper part of the sub-chamber directly connected to the human body cleaning device.

[0088] Specifically, when the heating element 2 heats the water flow in the heating chamber 11, the surface temperature of the heating element 2 is relatively high. When the water flow contacts the surface of the heating element 2, bubbles are generated. Compared with water, the density of bubbles is lower than that of water and they tend to float upward. The bubbles mixed in the water flow in the heating chamber 11 will float to the upper space of the heating chamber 11. A drainage port 112 is provided at the upper position of the heating chamber 11, which is conducive to the bubbles in the heating chamber 11 to float up and smoothly enter the mixing chamber 12 through the drainage port 112, thereby preventing a large number of bubbles from accumulating in the heating chamber 11 and being unable to be eliminated.

[0089] Optionally, the mixing chamber 12 may include a plurality of sub-chambers, and the bubbles in the sub-chamber at the end of the water flow path of the mixing chamber 12 will also float to the upper position of the sub-chamber at the end of the water flow path, and the sub-chamber is connected to the first water outlet 121, and the first water outlet 121 is arranged at the upper part of the sub-chamber, which is conducive to the bubbles floating to the upper part of the sub-chamber being discharged to the outside of the shell 1 through the first water outlet 121.

[0090] In an exemplary embodiment, Figures 9 to 13 As shown, the heating device also includes a guide member 4; the guide member 4 is arranged in the heating chamber 11, and together with the shell 1 and the heating member 2, encloses a heating channel 16; the heating channel 16 is connected to the first water inlet 111, and is connected to the head end chamber of the mixing chamber through the connecting flow path 13.

[0091] The heating element 2 is a heating rod 21 . A first gap 161 is defined between the heating rod 21 and the housing 1 . A second gap 162 is defined between the heating rod 21 and the guide element 4 .

[0092] Specifically, a flow guide 4 is arranged in the heating chamber 11, and the flow guide 4, the shell 1 and the heating element 2 enclose a heating flow channel 16. A first gap 161 is provided between the heating rod 21 and the shell 1, and a second gap 162 is provided between the heating rod 21 and the flow guide 4, so that the water in the heating flow channel 16 surrounds the outer surface of the heating element 2, increasing the contact area between the water and the outer surface of the heating element 2, thereby improving the heating efficiency of the heating device. In addition, the flow guide 4 allows the water in the heating chamber 11 to flow along a set water flow path, thereby increasing the drainage speed of the heating chamber 11 and preventing a large number of bubbles from accumulating in the heating chamber 11.

[0093] In an exemplary embodiment, Fig.15 and Fig.16As shown, a spiral partition rib 5 is provided in the heating channel 16. The partition rib 5 is sleeved and connected to the outer wall of the heating rod 21 and is connected to the outer cavity wall of the heating channel 16. The partition rib 5, the heating rod 21, the shell 1 and the guide member 4 enclose a spiral channel 163.

[0094] Specifically, the length of the water flow path of the spiral flow channel 163 is longer and the flow path cross-section is smaller, so the flow rate is faster. When water flows along the spiral flow channel 163, the water flow is in a turbulent state, and the inner layer of water in contact with the side wall of the heating rod 21 is always in a state of replacement with the outer layer of water in the flow path cross-section, so the water has a mixing effect during the flow process. The water on the surface of the heating rod 21 is quickly replaced, thereby reducing the probability that the water temperature outside the side wall of the heating rod 21 rises to the boiling point, thereby reducing the generation of bubbles. In addition, the water flow rate of the spiral flow channel 163 is faster, which reduces the probability of bubbles gathering and becoming larger, and is also conducive to the water flow to carry away the bubbles.

[0095] Fig.15 is a schematic diagram of the cross-sectional structure of a heating device having a spiral flow channel 163, Fig.16 It is a schematic diagram of the structure in which the partition rib 5 is wrapped around the outer side wall of the heating rod 21 .

[0096] In an exemplary embodiment, Fig.17 and Fig.18 As shown, the guide member 4 is also provided with a drainage channel 41 , the input end of the drainage channel 41 is connected to the heating channel 16 , the output end of the drainage channel 41 is connected to the connecting flow path 13 , and the input end of the drainage channel 41 is located at the top of the heating channel 16 .

[0097] Specifically, Fig.17 and Fig.18 In the embodiment of the heating device shown, the diverter plate 3 is not shown in the mixing chamber 12. Fig.18 As shown, since the bubbles in the heating channel 16 will float to the upper part of the heating channel 16, the input end of the drainage channel 41 is set at the top of the heating channel 16, which is beneficial for the bubbles located in the upper part of the heating channel 16 to flow into the connecting flow path 13 and the mixing chamber 12 through the drainage channel 41.

[0098] In an exemplary embodiment, Fig.14 As shown, one end of the housing 1 is provided with an opening 17, and the heating device further comprises a mounting seat 6, which is connected to the housing 1 and covers the opening 17; the heating element 2 is connected to the mounting seat 6. The opening 17 comprises the first opening and the second opening mentioned above.

[0099] like Fig.10 and Fig.11 As shown, the guide member 4 is provided with a first guide channel 411 communicating with the heating channel 16 and a second guide channel 412 communicating with the connecting channel 13. Fig.12As shown, the end of the guide member 4 facing the mounting seat 6 and the mounting seat 6 enclose a temperature measurement cavity 42, and the temperature measurement cavity 42 connects the first guide channel 411 and the second guide channel 412; the guide channel 41 includes the first guide channel 411, the temperature measurement cavity 44 and the second guide channel 412. Fig.12 As shown, the temperature measuring cavity 42 is distributed in a spiral shape, the water flow input end 421 of the temperature measuring cavity 42 is located at the center of the spiral, the water flow output end 422 of the temperature measuring cavity 42 is located radially outside the spiral, and the water flow output end 422 is higher than the water flow input end 421.

[0100] Specifically, Fig.14 As shown, the heating element 2 of the present application is connected to the mounting seat 6, the guide member 4 is inserted into the avoidance space enclosed by the heating element 2 and the mounting seat 6, and then the heating element 2 and the guide member 4 are inserted into the heating chamber 11 together to heat the water in the heating chamber 11.

[0101] Figures 11 to 13 The direction of the arrows indicates the water flow path. The water flow path of the heating device of the embodiment of the present application is: water enters the first flow guide channel 411 from the heating flow channel 16, and then enters the temperature measurement cavity 42 from the beam input port 421, and then flows along the heating flow channel 16. Fig.12 The water flows in the path indicated by the arrow, enters the second flow guide channel 412 from the water flow output end 422 , and then flows into the connecting flow path 13 and the mixing chamber 12 .

[0102] The temperature measuring cavity 42 is distributed in a spiral shape, and the depth of the temperature measuring cavity 42 along the axial direction of the heating element 2 is as small as possible, so as to reduce the flow area of ​​the temperature measuring cavity 42, increase the flow rate of the temperature measuring cavity 42, and make the bubbles entering the temperature measuring cavity 42 flow into the mixing cavity along with the accelerated flow of the water. The bubbles tend to float upward, and the water flow output end 422 is higher than the water flow input end 421, which is conducive to the bubbles mixed with the water flow entering the temperature measuring cavity 42 to float upward and leave the temperature measuring cavity 42.

[0103] In an exemplary embodiment, Figure 8 , Fig.14 and Fig.17 As shown, the temperature control switch assembly 7 is installed on the mounting seat 6 , and the temperature control switch assembly 7 is arranged opposite to the temperature measuring cavity 42 .

[0104] Specifically, the temperature control switch assembly 7 is mounted on the mounting seat 6, and the temperature control switch assembly 7 is arranged opposite to the temperature measuring chamber 42. The water is heated in the heating channel 16 and then enters the temperature measuring chamber 42. The water temperature in the temperature measuring chamber 42 can be transmitted to the temperature control switch assembly 7 through the mounting seat 6. Since the temperature measuring chamber 42 is located between the heating channel 16 and the mixing chamber 12 along the water flow direction, the water temperature of the water heated in the heating channel 16 can be fed back to the temperature control switch assembly 7 in a timely manner. Compared with the method of using the temperature control switch assembly to measure the water temperature in the mixing chamber in the prior art, the temperature control switch assembly 7 of the present application is more sensitive to detect the water temperature fluctuation in the heating channel 16.

[0105] In an exemplary embodiment, Fig. 9 , Fig.11 , Fig.13 and Fig.18 As shown, an air cavity 43 with an opening facing downward is provided in the flow guide 4 , and the air cavity 43 is communicated with the heating flow channel 16 .

[0106] Specifically, the air cavity 43 is connected to the heating channel 16 through a connecting gap, and gas is stored in the air cavity 43. The gas in the air cavity 43 can balance the water flow pressure in the heating channel 16 to prevent water pressure fluctuations in the heating channel 16. When the water pressure in the heating channel 16 increases, the water in the heating channel 16 flows to one side of the air cavity 43 through the connecting gap, so that the volume of the air cavity 43 decreases and the air pressure increases. The increase in air pressure in the air cavity 43 balances the water flow pressure in the heating channel 16. When the water pressure in the heating channel 16 decreases, the gas in the air cavity 43 enters the heating channel 16 through the connecting gap, the volume of the gas in the air cavity 43 increases, and the air pressure decreases, thereby balancing the water flow pressure fluctuations in the heating channel 16.

[0107] It is understood that a small amount of bubbles contained in the water flow in the heating flow channel 16 will enter the air cavity 43 through the connecting gap. The gas in the air cavity 43 and the water flow in the heating flow channel 16 will also exchange heat, and the gas in the air cavity 43 can balance the water temperature fluctuation in the heating flow channel 16.
