Description

Technical Field

[0001] The present application relates to heating equipment technology, in particular to a mixing device, a heating device and a toilet. Background Art

[0002] A heating device is usually provided in a smart toilet, and the heating device includes a hot water supply unit, which heats water to obtain hot water for use in the human body cleaning device of the toilet.

[0003] Instructions attached Figure 1 It is a schematic diagram of the cross-sectional structure of a heating device in the prior art. Specifically, a heating element 2 is provided in the heating chamber 11 of the housing 1, and cold water is injected into the heating chamber 11 to take out the hot water in the heating chamber 11. The injected cold water causes the water temperature in the heating chamber 11 to drop, and the hot water in the heating chamber 11 flows upward, and the cold water in the heating chamber 11 flows downward. The water flow in the heating chamber 11 is chaotic and disorganized, resulting in uneven distribution of water temperature at different positions of the heating chamber 11, poor consistency of water temperature in the heating chamber 11, and poor stability of the water temperature of the water flow discharged from the housing 1. When the hot water discharged from the heating chamber 11 is used in a human body cleaning device on a toilet, the hot water temperature obtained by the human body cleaning device has poor consistency, and the user experience is poor.

[0004] At present, some heating devices include, in addition to a hot water supply unit provided with a heating chamber, a mixing device for mixing water. A heating element is provided in the heating chamber, and the water in the heating chamber is heated by the heating element to increase its temperature. Due to the fast flow rate of the water in the heating chamber and the stratification of the water flow based on the different water temperatures, the water temperature distribution in the heating chamber is uneven. Water flows from the heating chamber into the mixing device so that the water temperature of the water flow is further mixed. At present, the water flow path in the mixing device is chaotic and irregular, and the water flows rapidly in the inner cavity of the mixing device and is directly discharged from the water outlet of the mixing device. Due to the poor consistency of the water temperature in the heating chamber, the current mixing device cannot make the water temperature mix evenly when the water flow rate is fast. Therefore, the water temperature mixing effect of the mixing device in the prior art is poor, and the consistency of the water temperature discharged from the mixing device is poor. Summary of the invention

[0005] In order to solve the above-mentioned problems, the present application provides a mixing device, a heating device and a toilet. The mixing device is provided with at least two water flow channels, and the at least two water flow channels can divide the water flowing into the mixing device from the hot water supply unit so that the water flow is divided into at least two water flows. In this way, the mixing chamber located on the downstream side of the at least two water flow channels can mix the multiple water flows that flow in the branches more evenly, so that the water temperature stability of the water discharged from the mixing device is good.

[0006] The specific technical solutions of the embodiments of this application are as follows: A mixing device, which connects a hot water supply unit and a human body washing device on a toilet, and is used to provide washing water for the human body washing device; the mixing device is provided with an outer wall, a mixing chamber and at least two water flow channels, and the mixing chamber and the at least two water flow channels are both arranged in a cavity enclosed by the outer wall; the mixing chamber is connected to the human body washing device; the at least two water flow channels can divide the water flowing from the hot water supply unit into the mixing device so that the water flow is divided into at least two water flows; the mixing chamber is arranged on the downstream side of the at least two water flow channels so as to mix the divided water flows.

[0007] A heating device comprises a hot water supply unit and a mixing device as described in the above embodiment, wherein the hot water supply unit comprises a shell and a heating element, the shell is provided with a heating chamber, the heating element is arranged in the heating chamber, the heating element is used to heat water in the heating chamber, and the heating chamber is connected to a cavity enclosed by an outer wall of the mixing device.

[0008] A toilet comprises a human body cleaning device and the heating device as described in the above embodiment.

[0009] The technical effects of the mixing device in the embodiment of the present application are as follows: The mixing device of the embodiment of the present application is provided with at least two water flow channels in the cavity enclosed by the outer wall, and the at least two water flow channels can divide the water entering the mixing device into at least two water flows. The at least two water flows flow into the mixing chamber located on the downstream side of the water flow channels and converge and collide together in the mixing chamber. In this way, there is a mixed flow mode in which multiple water flows intersect and converge in the mixing chamber, so that the water flows in the mixing chamber are mixed more evenly and the water outlet temperature of the mixing chamber is more consistent.

[0010] Specifically, for example, the cavity enclosed by the outer wall includes a plurality of sub-chambers, and the water in at least one sub-chamber on the upstream side flows into at least one sub-chamber on the downstream side in the form of split-flow of water flow, so that the sub-chamber on the downstream side can form a situation of multiple flows of water flow and intense convection heat exchange, so that the water temperature mixing in the cavity of the mixing device is more uniform. Among them, the specific form of the split-flow of water flow includes at least two situations: one situation is that the water flow flows in high and low layers according to different water temperatures, and the other situation is that the water flow is divided into multiple streams of the same height. When the water flow forms a situation of stratified flow according to different temperatures in at least one sub-chamber on the downstream side, the high-temperature part of the water flow generally floats on the upper layer, and the low-temperature part of the water flow sinks to the lower layer. The stratified flow of water temperature in the sub-chamber makes the contact area between the laminar flows large and the heat exchange is sufficient, and the contact collision and heat exchange are relatively intense, so that the water temperature mixing in the sub-chamber is more uniform. When water in multiple sub-chambers flows to a sub-chamber on the downstream side, multiple water flows converge together in the sub-chamber on the downstream side. The convergence and collision of the multiple water flows are more intense, so that the water temperature mixing consistency in the chamber of the mixing device is better.

Other advantages of the present application can be realized and obtained by the schemes described in the description and the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] 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.

[0015] A smart toilet usually includes a hot water supply unit with a heating chamber, a mixing device for mixing water, and a human body washing device. It is understandable that the heating chamber and the mixing water chamber can be set on different bodies, thereby forming two independently distributed devices with heating water function and mixing water function respectively. The heating chamber and the mixing water chamber can also be integrated into the same body in an integrated design, thereby forming a multifunctional heating device with both heating water and mixing water functions. Among them, a heating element is usually set in the heating chamber to heat the water in the heating chamber; the function of the mixing device is to make the water temperature of the water flowing from the heating chamber into the inner cavity of the mixing device more evenly mixed.

[0016] Figure 3 and Figure 4 In the embodiment of the heating device shown, the heating chamber and the chamber for mixing water are integrated in the same body by an integrated design. The heating device has both heating and mixing functions. The heating device is provided with a housing 1, and the heating chamber 11 and the chamber for mixing water 12 are integrated in the housing 1. The heating chamber 11 is provided with a first water inlet 111, and the chamber for mixing water 12 is provided with a first water outlet 121. The chamber for mixing water 12 and the heating chamber 11 are connected through a connecting flow path 13, and a heating element 2 is provided in the heating chamber 11. Water flows into the heating chamber 11 from the first water inlet 111, and after being heated by the heating element 2, it enters the chamber for mixing water 12 through the connecting flow path 13, and finally flows out from the first water outlet 121.

[0017] Now, a specific embodiment of the mixing device with the water temperature mixing function is described in detail. Figures 8 to 10 As shown, an embodiment of the present application provides a mixing device, which is connected to a hot water supply unit and a human body cleaning device on a toilet, and is used to provide cleaning water for the human body cleaning device; the mixing device is provided with an outer wall, a mixing chamber and at least two water flow channels, and the mixing chamber and the at least two water flow channels are both arranged in a cavity enclosed by the outer wall; the mixing chamber is connected to the human body cleaning device; the at least two water flow channels can divide the water flowing into the mixing device from the hot water supply unit so that the water flow is divided into at least two water flows; the mixing chamber is arranged on the downstream side of the at least two water flow channels so as to mix the divided water flows.

[0018] The mixing device of the embodiment of the present application is provided with at least two water flow channels in the cavity enclosed by the outer wall, and the at least two water flow channels can divide the water entering the inner cavity of the mixing device into at least two water flows. The at least two water flows flow into the mixing chamber located on the downstream side of the water flow channels and converge and collide together in the mixing chamber. In this way, there is a mixed flow mode in which multiple water flows intersect and converge in the mixing chamber, so that the water flows in the mixing device of the present application are mixed more evenly and the water outlet temperature of the mixing device is more consistent.

[0019] The cavity enclosed by the outer wall may include a plurality of sub-chambers, and the mixing chamber mentioned above may refer to one of the sub-chambers, in which multiple streams of water flow and mix. Two adjacent sub-chambers have a common wall surface, and the water flow channel may include a connecting port located on the common wall surface, that is, the water flow channel may connect two adjacent sub-chambers. The water flow channel may also include a water flow channel connecting two non-adjacent sub-chambers, that is, the water flow channel flows through certain sub-chambers. For example, Fig. 9 As shown, the third communication port 127 includes two sub-communication ports, and the two sub-communication ports of the third communication port 127 are the two water flow channels described in the present application, and the two water flow channels can divide the water in the second chamber 123 into two streams and flow into the third chamber 124, and the third chamber 124 is a mixing chamber located at the downstream side of the two water flow channels. For another example, Figure 8 and Fig. 9 In the embodiment, the water in the first chamber 122 is divided into multiple water flows, one of which first enters the second chamber 123 through the first communication port 125 and then enters the third chamber 124 through the third communication port 127; the water in the first chamber 122 is divided into another water flow, which first enters the second chamber 123 through the second communication port 126 and then enters the third chamber 124 through the third communication port 127. Therefore, starting from the first communication port 125 through the second chamber 123 and entering the third communication port 127 is one water flow channel of the present application, and starting from the second communication port 126 through the second chamber 123 and entering the third communication port 127 is another water flow channel of the present application. The two water flow channels can divide the water in the first chamber 122 into two water flows.

[0020] The cavity enclosed by the outer wall may include a plurality of sub-chambers. The mixing chamber may be a sub-chamber directly connected to the human body washing device; the mixing chamber may not be directly connected to the human body washing device. The mixing chamber is one or more sub-chambers located on the downstream side of at least two water flow channels, and multiple water flows converge and flow into the mixing chamber to mix the water temperature evenly.

[0021] Specifically, in some embodiments, the cavity enclosed by the outer wall may include a plurality of sub-chambers, and the water in at least one sub-chamber on the upstream side flows into at least one sub-chamber on the downstream side in the form of split-flow of water flow, so that the sub-chamber on the downstream side can form a situation of multiple flows of water flow and intense convection heat exchange, so that the water temperature mixing in the inner cavity of the mixing device is more uniform. Among them, the specific form of the split-flow of water flow includes at least two situations: one situation is that the water flow flows in high and low layers according to different water temperatures, and the other situation is that the water flow is divided into multiple streams of the same height. When the water flow forms a situation of stratified flow according to different temperatures in at least one sub-chamber on the downstream side, the high-temperature part of the water flow generally floats on the upper layer, and the low-temperature part of the water flow sinks to the lower layer. The stratified flow of water temperature in the sub-chamber makes the contact area between the laminar flows large and the heat exchange is sufficient, and the contact collision and heat exchange are relatively strong, so that the water temperature mixing in the sub-chamber forming the stratified flow of water temperature is more uniform. When there are multiple water flows in a sub-chamber on the downstream side, but the multiple water flows have the same height and the same water temperature, the multiple water flows converge, collide and mix together, which also makes the water temperature of the downstream sub-chamber mixed more evenly.

[0022] In some embodiments, the cavity enclosed by the outer wall may include multiple sub-chambers, water in some of the sub-chambers flows to a sub-chamber on the downstream side (the sub-chamber is a mixing chamber), and multiple water flows converge together in the sub-chamber on the downstream side. The convergence and collision of the multiple water flows are more intense, so that the water temperature mixing consistency in the chamber of the mixing device is better.

[0023] In some embodiments, the cavity enclosed by the outer wall may also include a plurality of sub-chambers, one of which is directly connected to the hot water supply unit, and the sub-chamber is a hot water receiving chamber. When the water flowing out of the hot water receiving chamber passes through at least two water flow channels, the water is divided into at least two water flows that flow in the inner cavity of the heating device and then converge in the mixing chamber. In some embodiments, the cavity enclosed by the outer wall may also include at least three sub-chambers, at least two of which are directly connected to the hot water supply unit, and the at least two sub-chambers are hot water receiving chambers. The water flowing out of the multiple hot water receiving chambers flows into a mixing chamber, thus forming a flow mode in which multiple water flows flow to the mixing chamber. The mixing device also has at least two water flow channels.

[0024] The above specific embodiments are all within the protection scope of the technical solution of this application.

[0025] In an exemplary embodiment, a water outlet port is provided at the end of the water flow direction of the water flow channel; the water outlet ports of at least two water flow channels do not overlap and are directly connected to a mixing chamber, and the water outlet directions of the water outlet ports of the at least two water flow channels intersect in the mixing chamber.

[0026] Specifically, the water outlet directions of the water outlet ports of at least two water flow channels intersect in the mixing chamber, so that at least two water flows converge and intersect in the mixing chamber. The water flows in the mixing chamber collide more violently, so that the mixed water temperature of the mixing device of the present application is consistent.

[0027] As Fig. 9 Taking the embodiment of the mixing device shown as an example, the third communication port 127 includes two sub-communication ports, which are two water flow channels of the present application. The two water flow channels divide the water in the second chamber 123 into two water flows, and both water flows flow into the third chamber 124 to converge and mix in the third chamber 124, and the water outlet directions of the two sub-communication ports of the third communication port 127 intersect in the third chamber 124. The water flow flowing from the second chamber 123 into the third chamber 124 flows in separate streams and then intersects and converges together, so that the mixing and collision of multiple water flows in the third chamber 124, i.e., the mixing chamber, is more intense, and the water temperature in the third chamber 124 is mixed more evenly.

[0028] In an exemplary embodiment, a plurality of sub-chambers are provided in the cavity enclosed by the outer wall, the plurality of sub-chambers include a mixing chamber, a water inlet port is provided at the starting end of the water flow direction of the water flow channel, at least two water inlet ports of the water flow channels are directly connected to a sub-chamber, and the water inlet ports of the at least two water flow channels have different heights.

[0029] Specifically, one sub-chamber is connected to at least two water flow channels with different water inlet ports, and the two water inlet ports are at different heights, so that the water in the one sub-chamber is divided into at least two water flows, which flow into at least two water inlet ports at different heights respectively. The high-temperature water flow in the one sub-chamber flows upward, and the low-temperature water flow in the one sub-chamber flows downward, so that the water in the one sub-chamber is divided into multiple water flows according to different water temperatures, so that multiple water flows are formed in the inner cavity of the heating device to flow in layers according to different water temperatures, so that the contact area between the multiple layers of multiple water flows including the high-temperature and low-temperature water flows is increased, the heat exchange is fast, and the water temperature is evenly mixed.

[0030] As Figure 8 and Fig.10 Taking the embodiment of the mixing device shown as an example, the first communication port 125 and the second communication port 126 are two water flow channels connecting the first chamber 122 and the second chamber 123. The first communication port 125 and the second communication port 126 are at different heights. The high-temperature water in the first chamber 122 enters the second chamber 123 through the first communication port 125, and the low-temperature water in the first chamber 122 enters the second chamber 123, i.e., the mixing chamber, through the second communication port 126. In this way, two streams of high-temperature and low-temperature water flow into the second chamber 123. When the two streams of high-temperature and low-temperature water flow just enter the second chamber 123, they flow in layers. In this way, the contact area of ​​the high and low-temperature water flows is large, the collision of the multi-layer water flows is sufficiently strong, and the heat exchange is fast and sufficient.

[0031] For example, in Figure 8 In the embodiment of the mixing device shown, the first chamber 122 is connected to the third chamber 124 through the fourth connecting port 128, and the first chamber 122 is connected to the second chamber 123 and then to the third chamber 124 through the first connecting port 125 and the second connecting port 126 respectively. The water inlet port of the fourth connecting port 128 on the first chamber 122 is one water inlet port, and the water inlet ports of the first connecting port 125 and the second connecting port 126 on the first chamber 122 are two water inlet ports. The three water inlet ports have different heights, so that the water in the first chamber 122 is divided into three streams of water flowing out according to different water temperatures, which is conducive to the formation of multiple streams of water in the mixing chamber on the downstream side that flow in layers according to different water temperatures, so that the water temperature in the mixing chamber is fully and evenly mixed, and the discharge water temperature of the mixing device is consistent.

[0032] In an exemplary embodiment, at least two water inlet ports are directly connected to one sub-chamber, wherein a flow area of ​​a higher-positioned water inlet port is smaller than a flow area of ​​a lower-positioned water inlet port.

[0033] Specifically, a water inlet port at a higher position has a smaller flow area, so the water flow rate entering the higher water inlet port is small. A water inlet port at a lower position has a larger flow area, so the water flow rate entering the lower water inlet port is larger, which is conducive to forming a situation where the amount of high-temperature water is small and the amount of low-temperature water is large in the sub-chamber on the downstream side, so that the large amount of low-temperature water flowing from the hot water supply unit into the mixing device has a large number of mixed flows.

[0034] In an exemplary embodiment, a hot water receiving chamber directly connected to a hot water supply unit is provided in a cavity enclosed by the outer wall, one of the multiple sub-chambers is the hot water receiving chamber, and a water inlet port is provided on the cavity wall of the hot water receiving chamber.

[0035] Specifically, Figure 8 In the embodiment of the heating device shown, the shell 1 includes a heating chamber 11 and a mixed water chamber 12, and the heating chamber 11 and the mixed water chamber 12 are connected together through a connecting flow path 13. The mixed water chamber 12 is divided into a first chamber 122, a second chamber 123 and a third chamber 124. The first chamber 122 is a hot water receiving chamber, and the first chamber 122 is directly connected to the heating chamber 11. A plurality of water inlet ports connecting a plurality of water flow channels are provided on the cavity wall of the first chamber 122.

[0036] In an exemplary embodiment, the number of the plurality of sub-chambers is at least three, and the plurality of sub-chambers includes a hot water receiving chamber, a mixing chamber, and at least one other sub-chamber communicating with the hot water receiving chamber and the mixing chamber.

[0037] by Fig. 9 and Fig.10 Taking the embodiment of the mixing device shown as an example, the mixing device includes three sub-chambers, namely the first chamber 122, the second chamber 123 and the third chamber 124, wherein the first chamber 122 is a hot water receiving chamber, the third chamber 122 is a mixing chamber, and the second chamber 123 is another sub-chamber. It can be understood that the number of sub-chambers of the mixing device of the embodiment of the present application is not limited to three, and can also be four or more, all within the protection scope of the present application.

[0038] In an exemplary embodiment, at least one sub-chamber is connected to the hot water receiving chamber through a plurality of water inlet ports at different heights.

[0039] Specifically, in some embodiments, a sub-chamber is connected to a hot water receiving chamber through multiple water inlet ports of different heights, such that a sub-chamber is connected to a hot water receiving chamber through multiple water flow channels, and the water in the hot water receiving chamber is divided into multiple streams by the multiple water flow channels and finally converges into the sub-chamber. In some embodiments, a hot water receiving chamber is connected to multiple sub-chambers through multiple water flow channels, such that the water in the hot water receiving chamber is divided into multiple streams by the multiple water flow channels and flows to different sub-chambers.

[0040] In an exemplary embodiment, a hot water receiving chamber directly connected to a hot water supply unit is provided in a cavity enclosed by an outer wall, and the hot water receiving chamber and the mixing chamber have a common wall surface, and a water flow channel connecting the hot water receiving chamber and the mixing chamber is provided on the common wall surface; except for the hot water receiving chamber and the mixing chamber, other sub-chambers are connected to the hot water receiving chamber and the mixing chamber.

[0041] Specifically, between 8 and Fig.10 In the embodiment of the mixing device shown, the first chamber 122 is a hot water receiving chamber, the third chamber 124 is a mixing chamber, and the second chamber 123 is another sub-chamber. The first chamber 122 and the third chamber 124 have a common wall surface 31, and a fourth communication port 128, i.e., a water flow channel, is provided on the common wall surface 31. The fourth communication port 128 allows the water in the first chamber 122 to flow directly into the third chamber 124. Figure 8 As shown, the second cavity 123 is connected to the first cavity 122 , and the second cavity 123 is also connected to the third cavity 124 , thereby forming a water flow channel starting from the first cavity 122 , flowing through the second cavity 123 and finally entering the third cavity 124 .

[0042] The structural features of the mixing device and the water mixing chamber 12 of the present application are described in detail below based on the embodiments shown in the drawings of the specification of the present application as an example.

[0043] In an exemplary embodiment, Figures 8 to 10As shown, the mixing device includes a plurality of sub-chambers, the plurality of sub-chambers include a first chamber 122, a second chamber 123 and a third chamber 124, the first chamber 122 is a hot water receiving chamber, and the third chamber 124 is a mixing chamber; the plurality of sub-chambers are connected together through connecting ports, the plurality of connecting ports include a first connecting port 125, a second connecting port 126, a third connecting port 127 and a fourth connecting port 128.

[0044] The first cavity 122 is communicated with the second cavity 123 through the first communication port 125 and the second communication port 126 , and the second cavity 123 is communicated with the third cavity 124 through the third communication port 127 .

[0045] The first chamber 122 and the third chamber 124 are communicated with each other through the fourth communication port 128 .

[0046] The first communication port 125 is located higher than the second communication port 126 .

[0047] Specifically, the first chamber 122 is connected to the second chamber 123 through the first connecting port 125 and the second connecting port 126, and the position of the first connecting port 125 is higher than the second connecting port 126. Since the high-temperature water flow floats upward and the low-temperature water flow sinks, the low-temperature water flow in the first chamber 122 mainly flows into the second chamber 123 from the second connecting port 126, and the high-temperature water flow in the first chamber 122 mainly flows into the second chamber 123 from the first flow port 125, so that multiple streams of water flowing according to water temperature stratification are formed in the second chamber 123. The contact, collision and heat exchange of the two or more streams with high and low water temperatures in the second chamber 123 are relatively sufficient and intense, so that the water temperature in the second chamber 123 is mixed more evenly.

[0048] It can be understood that the number of the first communication port 125 and the second communication port 126 can be set to one or more, all within the protection scope of the present application.

[0049] The first chamber 122 and the third chamber 124 are connected through the fourth connecting port 128, and the second chamber 123 and the third chamber 124 are connected through the third connecting port 127, so that water from the first chamber 122 and the second chamber 123 flows into the third chamber 124 and intersects and mixes in the third chamber 124, and at least two water flows are formed in the third chamber 124 that intersect, collide and mix together, thereby increasing the water temperature mixing intensity in the third chamber 124 and making the water temperature mixing in the third chamber 124 more uniform.

[0050] In an exemplary embodiment, a flow area of ​​the first communication port 125 is smaller than a flow area of ​​the second communication port 126 .

[0051] Specifically, the flow area of ​​the second connecting port 126 is larger than the flow area of ​​the first connecting port 125, so as to control more low-temperature water in the first chamber 122 to flow into the second chamber 123 from the lower second connecting port 126, and control less high-temperature water in the first chamber 122 to flow into the second chamber 123 from the higher first connecting port 125, so that a large amount of low-temperature water in the first chamber 122 enters the second chamber 123 for water flow mixing, which is beneficial to improving the water temperature mixing consistency of the mixing device.

[0052] In addition, bubbles are mixed in the water flow entering the first cavity 122 from the connecting flow path 13, and some of the bubbles will float up and flow toward the first connecting port 125 at a higher position, so that the flow area of ​​the first connecting port 125 is controlled to be smaller than that of the second connecting port 126 at a lower position, thereby reducing the probability of bubbles passing through the first connecting port 125, thereby preventing more bubbles in the first cavity 122 from flowing into the second cavity 123.

[0053] In an exemplary embodiment, Figure 8 As shown, the third communication port 127 is located higher than the first communication port 125 .

[0054] Specifically, the third communication port 127 is higher than the first communication port 125, so that more high-temperature water in the mixed water flow entering the second chamber 123 flows into the third chamber 124 through the third communication port 127, which is conducive to the discharge of high-temperature water from the mixing chamber 12. In addition, the position of the third communication port 127 is higher than the first communication port 125, so that more bubbles in the second chamber 123 can flow into the third chamber 124 through the third communication port 127 and then be discharged through the first water outlet 121, which is conducive to the discharge of bubbles in the chamber of the mixing device.

[0055] It can be understood that the number of the third communication ports 127 can be set to one or more, all within the protection scope of the present application.

[0056] In an exemplary embodiment, Fig. 9 As shown, there are multiple third communication ports 127 , and along the direction from the second cavity 123 to the third cavity 124 , the water flow directions of the multiple third communication ports 127 tend to converge.

[0057] Specifically, along the direction from the second cavity 123 to the third cavity 124, the water flow directions of the plurality of third connecting ports 127 have a tendency to converge, so that the multiple streams of water flowing into the third cavity 124 from the plurality of third connecting ports 127 converge and impact together, thereby enhancing the mixing force of the water flow flowing from the second cavity 123 to the third cavity 124, and making the water flow in the third cavity 124 more evenly mixed.

[0058] In an exemplary embodiment, Figure 8 and Fig. 9As shown, the fourth communication port 128 is higher than the first communication port 125 , and the water inlet port of the fourth communication port 128 is located at the upper part of the first cavity 122 .

[0059] Specifically, since the high-temperature water in the first chamber 122 tends to float upward and the low-temperature water tends to settle downward, the fourth connecting port 128 is higher than the first connecting port 125, so that the high-temperature water flow in the first chamber 122 can enter the third chamber 124 through the fourth connecting port 128 located at a high position. Since the third chamber 124 is directly connected to the human body's cleaning device, this method ensures that the water discharged from the third chamber 124 is hot water.

[0060] Furthermore, the bubbles in the water flow in the first chamber 122 also float upward, so that most of the bubbles smoothly enter the third chamber 124 along the fourth connecting port 128 located at a high position, which is beneficial to the discharge of the bubbles in the mixing chamber 12 .

[0061] Alternatively, if Fig.10 As shown, the mixing device is connected to the water heat supply unit through the connecting flow path 13, and the flow area of ​​the fourth connecting port 128 is smaller than the flow area of ​​the connecting flow path 13, so that the bubbles entering the first chamber 122 from the hot water supply unit through the connecting flow path 13 can be squeezed and divided into more small bubbles when passing through the fourth connecting port 128 with a smaller flow area, so that the volume of the bubbles entering the third chamber 124 is smaller, which is conducive to the discharge of the bubbles from the first water outlet 121.

[0062] Optionally, the first water outlet 121 is located at the upper portion of the third cavity 124 so that bubbles floating on the upper portion of the third cavity 124 can be discharged smoothly.

[0063] In an exemplary embodiment, the mixing device is further provided with a diverter plate, which is located in the cavity surrounded by the outer wall, and the diverter plate is separate from the outer wall, and the diverter plate divides the cavity surrounded by the outer wall into a plurality of sub-chambers.

[0064] Specifically, due to the complex structure of the multiple sub-chambers, if the processing technology of integrally forming the diverter plate and the outer wall is complicated, the diverter plate and the outer wall are arranged as split types, which is conducive to simplifying the processing and manufacturing process of the mixing device. It can be understood that the diverter plate and the outer wall of the present application can also be integrally formed, which is within the scope of protection of the present application.

[0065] In an exemplary embodiment, a water outlet port is provided at the end of the water flow direction of the water flow channel, and a water inlet port is provided at the starting end of the water flow direction of the water flow channel. The water inlet port and / or the water outlet port are located at the connection position between the diverter plate and the outer wall.

[0066] Specifically, in the case of a split-type design of the diverter plate and the outer wall, the water inlet port and / or the water outlet port are located at the connection position between the diverter plate and the outer wall, so that when processing the diverter plate or the outer wall, a groove can be processed on the wall surface of the diverter plate or the outer wall to form a water flow channel. This method has a simple structural design and is easy to process and form.

[0067] In an exemplary embodiment, the water inlet port and / or the water outlet port are located on the diverter plate.

[0068] Specifically, the diverter plate and the outer wall adopt a split design. When processing the diverter plate, a water flow channel is processed in the middle of the wall of the diverter plate, which can also achieve the mixing water effect of the mixing device of the present application. This practice is within the protection scope of the present application.

[0069] It can be understood that the diverter plate and the outer wall are integrally formed, and the water inlet port and / or the water outlet port can also be located on the diverter plate.

[0070] In an exemplary embodiment, Figures 4 to 10 As shown, the outer wall encloses a chamber 12 for mixing water, the bottom wall of the chamber 12 for mixing water includes a protrusion 129 protruding into the interior of the chamber 12 for mixing water, and the mixing device also includes a diverter plate 3, the diverter plate 3 includes a first plate 31 and a second plate 32 connected to each other, the length direction of the first plate 31 is set to be the same as the length extension direction of the protrusion 129, and the lower end of the first plate 31 is connected to the top of the protrusion 129, and the upper end of the first plate 31 is connected to the top wall of the chamber 12 for mixing water, so that the space on one side of the width direction of the protrusion 129 forms a third chamber 124.

[0071] The second plate 32 is located on one side of the first plate 31 and is connected to 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 raised portion 129 and the bottom wall of the mixed water chamber 12, and the upper end of the second plate 32 is connected to the top wall of the mixed water chamber 12, so that the space on the other side of the raised portion 129 in the width direction forms the first cavity 122 and the second cavity 123.

[0072] The first communication port 125 is provided at the connection between the second plate 32 and the raised portion 129 , the second communication port 126 is provided at the lower end of the second plate 32 , and the third communication port 127 is provided at the connection between the first plate 31 and the raised portion 129 .

[0073] Specifically, Figure 6 and Figure 7As shown, a third connecting groove 1271 and a fourth connecting groove 1281 are provided on a plate surface of the first plate 31 of the diverter plate 3, and the third connecting groove 1271 includes a plurality of grooves with a convergence tendency. A first connecting groove 1251 and a second connecting groove 1261 are provided on a plate surface of the second plate 32. Along the water flow direction, the flow cross-sectional area of ​​the second connecting groove 1261 is greater than the flow cross-sectional area of ​​the first connecting groove 1251, the number of the second connecting grooves 1261 is set to be multiple, and the flow cross-sectional area of ​​the fourth connecting groove 1281 is smaller. The grooves on the plate surfaces of the first plate 31 and the second plate 32 of the diverter plate 3 and the upper wall surface of the protrusion 129 together form the respective connecting ports. It can be understood that the grooves are provided on the outer wall surface of the diverter plate 3 to facilitate the processing of the grooves and the adjustment of the size of the grooves.

[0074] In the specification of this application Figures 8 to 10 In the illustrated embodiment, the water flow mixing process in the mixed water chamber 12 is as follows: the water entering the first chamber 122 from the heating chamber 11, its high-temperature water flow and most of the bubbles will flow upward along the wall surface of the raised portion 129, enter the fourth connecting port 128, and then enter the third chamber 124; the low-temperature water flow in the first chamber 122 sinks to the bottom wall surface of the first chamber 122, and enters the second chamber 123 through the second connecting port 126; the medium-temperature water flow in the first chamber 122 will float a path along the wall surface of the raised portion 129 and enter the second chamber 123 through the first connecting port 125. The multiple water flows entering the second chamber 123 flow in layers according to different water temperatures, further mix and collide, and float along the wall of the raised portion 129 into the third connecting port 127. The water flows flowing along the multiple third connecting ports 127 tend to converge when entering the third chamber 124, and further collide and mix in the third chamber 124; the water flows entering the third chamber 124 from the third connecting port 127 and the water flows entering the third chamber 124 from the fourth connecting port 128 converge and collide again, so that the multiple water flows in the third chamber 124 are fully mixed and the water temperature is more consistent.

[0075] It can be understood that a raised portion 129 is provided on the bottom wall of the mixing water chamber 12, so that in the process of water entering the third chamber 124 from the first chamber 122 and in the process of water entering the third chamber 124 from the second chamber 123, the flow area of ​​the water flow is suddenly reduced, so that the water flow velocity is accelerated, which is beneficial to enhancing the mixing force of the water flow in the third chamber 124.

[0076] Fig.10 The arrows in the figure indicate the direction of water flow.

[0077] In an exemplary embodiment, the outer wall includes a first opening, and the splitter plate is configured to be placed into a cavity enclosed by the outer wall through the first opening.

[0078] Specifically, in Figure 8 In the illustrated embodiment, the mixed water chamber 12 is provided with an opening, which is a first opening, so that the diverter plate 3 can be installed in the cavity surrounded by the outer wall through the first opening, which facilitates the assembly and disassembly of the diverter plate.

[0079] Please refer to the instruction manual Figures 2 to 20 The present invention provides a heating device according to an embodiment of the present invention. Figures 4 to 9 As shown, it includes a hot water supply unit and a mixing device as described in the above exemplary embodiment, 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 cavity enclosed by the outer wall of the mixing device.

[0080] Specifically, the heating device of the embodiment of the present application includes the mixing device described in any one of the above exemplary embodiments, and thus has the structural features and advantages of the mixing device described in any one of the above exemplary embodiments, which will not be described in detail here.

[0081] The cavity enclosed by the outer wall of the mixing device is a mixing water chamber 12, and the heating chamber 11 is connected to the mixing water chamber 12, so that the water heated by the heating element 2 in the heating chamber 11 can enter the mixing water chamber 12, so that the water temperature is mixed more evenly.

[0082] It is understandable that the heating chamber 11 and the water mixing chamber 12 can be integrated into one body; the heating chamber 11 and the water mixing chamber 12 can also be designed as split parts, formed on two independent devices, all of which are within the protection scope of this application.

[0083] In an exemplary embodiment, Figures 3 to 10 As shown, the housing 1 and the outer wall of the mixing device are formed in one piece.

[0084] Specifically, the housing 1 and the outer wall of the mixing device are integrally formed, so that the heating chamber 11 provided with the heating element 2 and the mixing device for mixing water are integrated into one body, which can save the space occupied by the entire device.

[0085] In an exemplary embodiment, Figure 4 , Figure 5 and Figure 8 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.

[0086] 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 and Figure 3As shown, a mounting seat 8 is provided to block the first opening and the second opening at the same time.

[0087] In an exemplary embodiment, Figures 3 to 11 As shown, the heating device comprises a housing 1, a heating element 2 and a diverter plate 3. The housing 1 is provided with a heating chamber 11 and a chamber 12 for mixing water, a connecting flow path 13 is provided between the chamber 12 for mixing water and the heating chamber 11, the heating chamber 11 is provided with a first water inlet 111, and the chamber 12 for mixing water is provided with a first water outlet 121; the chamber 12 for mixing water is divided into a plurality of sub-chambers by the diverter plate 3, one of the sub-chambers is a hot water receiving chamber, which is directly connected to the connecting flow path 13, and one of the sub-chambers is a mixing chamber, which is directly connected to the first water outlet 121.

[0088] The heating device of the embodiment of the present application integrates the heating chamber 11 and the mixing water chamber 12 on a housing 1, so that the heating device of the embodiment of the present application has the functions of heating water and mixing water. Water flows into the heating chamber 11 from the first water inlet 111, and after being heated by the heating element 2, it enters the mixing water chamber 12 through the connecting flow path 13, and finally flows out from the first water outlet 121. The water temperature distribution in the heating chamber 11 is uneven. The water flow in the heating chamber 11 enters the mixing water chamber 12, making the water temperature mixing more uniform, and the water flow with a stable water temperature discharged from the mixing water chamber 12 flows into the human body cleaning device of the toilet, which improves the user experience.

[0089] In an exemplary embodiment, Fig.11 As shown, the heating device further comprises a temperature sensor 4, which is connected to the housing 1, and a probe of the temperature sensor 4 is inserted into the hot water receiving chamber.

[0090] Specifically, the temperature sensor 4 is used to collect the water flow temperature in the mixed water chamber 12. The probe of the temperature sensor 4 is inserted into the hot water receiving chamber so that the temperature sensor 4 can collect the water temperature rise data in the heating chamber 11 in time.

[0091] Alternatively, if Fig.11 As shown, the temperature sensor 4 is arranged near the communicating flow path 13, the top wall of the mixed water chamber 12 of the housing 1 is provided with a mounting portion 12-10, and one end of the temperature sensor 4 away from the probe 4 is connected to the mounting portion 12-10.

[0092] In an exemplary embodiment, Fig.12 and Figure 16-Figure 18 As shown, the heating device also includes a guide member 5; the guide member 5 is arranged in the heating chamber 11, and together with the shell 1 and the heating element 2, encloses a heating channel 112; the heating channel 112 is connected to the first water inlet 111, and is connected to the hot water receiving chamber through the connecting flow path 13.

[0093] Specifically, Fig.16 As shown, the guide member 5, the inner cavity wall of the shell 1 and the heating element 2 enclose a heating channel 112, so that the heating channel 112 surrounds the side wall surface of the heating element 2 and extends along the length extension direction of the heating element 2, so that the water in the heating channel 112 can fully contact the heating element 2, the contact area between the water and the heating element 2 is large, and the heating efficiency is high.

[0094] When water flows in the heating channel 112 and is heated by the heating element 2, stratification will occur. The high-temperature water is located above the heating channel 112, and the low-temperature water is located below the heating channel 112. The water temperature close to the outer wall of the heating element 2 is high, and the water temperature far from the outer wall of the heating element is low, which makes the water temperature distribution in the heating chamber 11 uneven. When the water in the heating channel 112 is heated by the heating element 2, bubbles will be generated. Finally, the water with uneven water temperature and the bubbles flow into the mixing water chamber 12 of the mixing device.

[0095] Optionally, in Fig.16 In the illustrated embodiment, the heating element 2 is U-shaped, and the heating channel 112 also extends in a U-shape.

[0096] In an exemplary embodiment, Figure 3 , Figures 12 to 15 As shown, the heating device of the present application further includes a temperature control switch assembly 7 and a mounting seat 8, the heating element 2 is connected to the mounting seat 8, the heating element 2 and the mounting seat 8 surround an escape space, and the guide member 5 is inserted into the escape space of the heating element 2. Fig.13 and Fig.14 As shown, Fig.13 The arrow in the figure indicates the moving direction of the guide member 5. The lower contour of the guide member 5 is smaller than the avoidance space, and the upper contour of the guide member 5 is larger than the avoidance space. In this way, the guide member 5 moves downward from the upper position of the heating element 2, so that the lower contour of the guide member 5 passes through the avoidance space, and the upper contour of the guide member 5 is located at the upper part of the avoidance space, forming Fig.14 The schematic diagram of the assembly structure of the heating element 2, the flow guide 5 and the mounting seat 8 is shown. Fig.15 As shown, Fig.15 The directions of the arrows in the figure respectively indicate the moving directions of the temperature control switch assembly 7 and the heating element 2. The ends of the heating element 2 and the guide member 5 facing away from the mounting seat 8 are inserted into the heating chamber 11. The mounting seat 8 covers the opening of the shell 1, and the temperature control switch assembly 7 is installed to the side of the mounting seat 8 facing away from the heating chamber 11.

[0097] like Fig.12 As shown, a temperature measuring groove is provided at one end of the flow guide 5 close to the mounting seat 8. The temperature measuring groove is a spiral groove 51. Fig.18As shown, the wall of the temperature measuring tank and the mounting seat 8 enclose a temperature measuring chamber 14, and the temperature measuring chamber 14 is connected to the heating flow channel 112 and the mixed water chamber 12. The temperature control switch assembly 7 is arranged opposite to the temperature measuring chamber 14. The water flow temperature in the temperature measuring chamber 14 can be transmitted to the temperature control switch assembly 7 so that the temperature control switch assembly 7 can be operated.

[0098] like Fig.12 and Fig.18 As shown, a snap-fitting portion 52 is provided on both sides of the guide member 5, and a snap-fitting portion 15 is provided on the cavity wall of the heating cavity 11 of the shell 1. The snap-fitting portion 52 and the snap-fitting portion 15 are snap-fitted to form a sealed connection structure to ensure that the water flow in the heating channel 112 flows along the set path and does not penetrate into the connection position between the shell 1 and the guide member 5.

[0099] Fig.18 The arrow in the figure shows the water flow path of the temperature measuring chamber 14. A water outlet is provided at the center of the spiral groove 51, and a water inlet is provided at the radial end of the spiral groove 51. The water in the heating flow channel 112 flows into the temperature measuring chamber 14 from the center of the spiral groove 51, and then flows along the Fig.18 The water flows in the direction of the arrow shown, and then flows out from the radial end of the spiral groove 51, and flows into the connecting flow path 13 and the chamber 12 of the mixed water.

[0100] In an exemplary embodiment, Figure 2 , Fig.19 and Fig. 20 As shown, the heating device further comprises a pump 6, which is provided with a water inlet 62 and a water outlet 61, the water outlet 61 is communicated with the first water inlet 111, and the water inlet 62 is communicated with a water storage member (not shown in the figure).

[0101] Specifically, the pump 6 is used to provide hydraulic power for the heating device, the purpose of which is to stabilize the water flow rate of the heating device. A stable water flow rate is conducive to controlling the heating power of the heating element 2.

[0102] The water flow path of the heating device of one embodiment of the present application is as follows: the water source of the water storage component enters the pump 6 through the water inlet 62, then flows out from the water outlet 61 of the pump 6, flows into the first water inlet 111 of the shell 1, enters the heating flow channel 112, flows along the heating flow channel 112, is heated by the heating component 2, enters the temperature measuring chamber 14, and then passes through the connecting flow path 13, enters the hot water receiving chamber of the mixing water chamber 12, passes through multiple sub-chambers of the mixing device, is divided into multiple water flows by multiple water flow channels, and finally enters the mixing chamber directly connected to the human body cleaning device, and flows out from the first water outlet 121.

[0103] The practice in the prior art of using a pressure stabilizing system and a flow meter to control the discharge volume of the heating device is limited by passive water pressure. When the water pressure of the water supply source drops suddenly, the water pressure of the water supply source directly causes the water flow in the heating chamber to decrease. The flow meter can detect the decrease in the water flow in the heating chamber, but there is a lag in the system's adjustment of the heating power of the heating element, resulting in a mismatch between the power of the heating element and the flow in the heating chamber, causing the discharge water temperature of the heating device to fluctuate, reducing the user experience.

[0104] The heating device of the embodiment of the present application uses the pump 6 to provide hydraulic power, which can avoid the water pressure change of the water supply source causing the change of the water flow in the heating chamber, stabilize the water output of the heating device, and simplify the power adjustment action of the heating device. In addition, the pump 6 can actively adjust the water flow in the heating chamber to ensure the stability of the drainage water temperature of the heating device, thereby improving the customer experience.

[0105] In an exemplary embodiment, Fig.19 As shown, the outer wall of the shell 1 is provided with a radial limiting portion and an axial limiting portion, the radial limiting portion includes a bracket 16, the pump 6 is placed on the bracket 16, and a first buffer is provided between the pump 6 and the bracket 16; a clamping portion is provided at one axial end of the pump 6, and a clamping fitting portion is provided on the outer wall of the shell 1, the clamping portions and the clamping fitting portions are clamped together, a second buffer is provided between the clamping portions and the clamping fitting portions, and the axial limiting portion includes a clamping fitting portion.

[0106] Specifically, foam may be provided in at least one of the pump 6 and the bracket 16 as a first buffer.

[0107] It can be understood that the pumping and drainage action of the pump 6 generates vibration, which is transmitted to the housing 1 and causes resonance of the housing 1. Buffers are provided between the housing 1 and the radial limiting portion and the axial limiting portion of the pump 6 to reduce the vibration noise of the isolation pump 6 and ensure the normal operation of the heating device.

[0108] In an exemplary embodiment, Figure 4 As shown, the axial limiting portion includes a hanger 17 located on the outer wall of the housing 1, and the hanger 17 is provided with a hanger hole 171. Fig.19 As shown, a connecting column 63 and a flexible protrusion 64 are provided at one end of the pump 6 axially away from the water inlet 62. The connecting column 63 is inserted into the hanging hole 171, and the flexible protrusion 64 is squeezed and deformed by the hanging hole 171 and passes through the hanging hole 171. The flexible protrusion 64 passing through the hanging hole 171 recovers its deformation again to prevent the connecting column 63 from being separated from the hanging hole 171. It can be understood that the flexible protrusion 64 has the function of buffering and reducing vibration.

[0109] In an exemplary embodiment, the water outlet 61 of the pump 6 is connected to the first water inlet 111 by a flexible pipe, and the water inlet 62 of the pump 6 is connected to the water storage member by a flexible pipe.

[0110] Specifically, Fig.19 As shown, the water outlet 61 of the pump 6 and the first water inlet 111 can be connected by a pipeline 9 made of soft rubber material, and the water inlet 62 of the pump 6 and the water storage member can also be connected by a pipeline made of soft rubber material.

[0111] Specifically, the flexible pipe not only has the function of guiding water flow and connecting pipelines, but also has the function of buffering and reducing vibration.
