Description

Technical Field

[0001] The present invention relates to the technical field of heating equipment, and in particular to a heating device and a toilet. Background Art

[0002] Smart toilets are usually equipped with a heating device, which is used to obtain warm water for use in the toilet's human body cleaning device. The heating device of the prior art is usually set as a heat storage heating method. Fig.18 A schematic diagram of the cross-sectional structure of a heat storage heating device of the prior art is shown. Specifically, the heating device is provided with a shell 1, in which a heating chamber 11 is provided, and a heating element 4 is placed in the heating chamber 11 to heat the water in the heating chamber 11. The power source for discharging the warm water is to inject cold water into the heating chamber 11 through a water inlet connected to the heating chamber 11. When providing hot water for the human body washing device, it is necessary to wait until the water in the heating chamber 11 is completely heated to a predetermined temperature before it can be used. In order to satisfy the user's ability to use suitable warm water in a timely manner, the water in the heating chamber 11 needs to be kept warm, and this method consumes a lot of energy. Summary of the invention

[0003] Based on the above problems, the inventor of the present application proposed a heating device, in which a flow guide and a heating element are inserted into a heating chamber, so that the wall surface of the heating chamber, the flow guide and the heating element enclose a heating channel surrounding the outer peripheral wall of the heating element, so as to achieve the purpose of instant heating and improving heating efficiency. However, the heating device has the following problems: when the heating element is inserted into the heating chamber, the heating element is skewed relative to the wall surface of the heating chamber or the flow guide, resulting in an uneven gap between the outer peripheral wall of the heating element and the cavity wall of the heating chamber, resulting in uneven heating of the water in the heating channel and poor consistency of water temperature in the heating channel.

[0004] In order to solve the above problems, an embodiment of the present application provides a heating device and a toilet, in which a limiting structure is arranged in the heating chamber of the heating device to cooperate with the limiting structure of the outer peripheral wall of the heating element. The limiting portion can limit the swinging of the heating element relative to the shell in the direction of the limiting portion, thereby ensuring that when the heating element is inserted into the heating chamber, the swing direction of the heating element relative to the guide member and the wall of the heating chamber is predictable. The predictable swing direction facilitates the control of the gap value of the heating channel, thereby solving the problem that the gap value of the heating channel does not meet the expected value.

[0005] The specific technical solutions of the embodiments of this application are as follows: A heating device, comprising: A housing is provided with a heating chamber, wherein the heating chamber is provided with a first opening; A mounting seat, covering the first opening and connected to the housing; A heating element, supported on the mounting seat, the heating element comprising a heating portion inserted into the heating cavity; a flow guide, supported by the mounting seat and / or the heating element, the flow guide being inserted into the heating chamber; the housing, the flow guide and the heating part enclose a heating flow channel surrounding the outer peripheral wall of the heating part; and A limiting structure is arranged in the heating chamber, the limiting structure is supported by the guide member or the mounting seat, and the limiting structure includes a limiting portion, which is arranged on the outside of the outer peripheral wall of the heating portion to limit the heating member from swinging relative to the shell toward the limiting portion.

[0006] A toilet comprises a human body washing device for providing washing water to a user and a heating device as described in the above embodiment, wherein the heating device is used to heat water and provide the water to the human body washing device.

[0007] The technical effects of the heating device in the embodiment of the present application are as follows: The heating device provided in the embodiment of the present application has a limiting structure arranged in the heating chamber, the limiting structure is supported on the flow guide or the mounting seat, and the limiting structure includes a limiting portion, the limiting portion is arranged close to the outer peripheral wall of the heating portion, and a limiting matching relationship is formed between the limiting portion and the outer peripheral wall of the heating portion. In this way, during the assembly process of the heating portion being inserted into the heating chamber, the limiting portion can prevent the heating portion from deflecting in the direction of the limiting portion, thereby ensuring that the deflection direction of the heating portion relative to the flow guide and the wall of the heating chamber is predictable during and after the heating portion is inserted into the heating chamber. The predictable deflection direction facilitates the control of the gap value of the heating channel, thereby solving the problem that the gap value of the heating channel does not meet the expected value.

[0008] The heating device of the present application can ensure that the gap value of the flow cross-section of the heating flow channel is uniform, the water at different positions in the heating flow channel is heated evenly, the water in the heating flow channel is heated and the temperature rise is consistent, thereby ensuring the heating efficiency of the heating device.

DETAILED DESCRIPTION

[0012] 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.

[0013] Please refer to the instruction manual Figures 1 to 17 The structural schematic diagram of the heating device of an embodiment of the present application is shown. Figure 6 , Fig.13 and Fig.17 The direction of the arrow in the figure indicates the direction in which the parts move during assembly. Figures 1 to 7 As shown, an embodiment of the present application provides a heating device, including a shell 1, a mounting seat 2, a flow guide 3, a heating element 4 and a limiting structure 5. The shell 1 is provided with a heating chamber 11, and the heating chamber 11 is provided with a first opening 111. The mounting seat 2 is covered with the first opening 111 and connected to the shell 1; the heating element 4 is supported on the mounting seat 2, and the heating element 4 includes a heating part inserted into the heating chamber 11. The flow guide 3 is supported on the mounting seat 2 and / or the heating element 4, and the flow guide 3 is inserted into the heating chamber 11; the shell 1, the flow guide 3 and the heating part enclose a heating flow channel 13 surrounding the outer peripheral wall of the heating part; the limiting structure 5 is provided in the heating chamber 11, the limiting structure 5 is supported on the flow guide 3 or the mounting seat 2, and the limiting structure 5 includes a limiting part, and the limiting part is arranged on the outer side of the outer peripheral wall of the heating part to limit the heating element 4 from swinging relative to the shell 1 in the direction of the limiting part.

[0014] Specifically, Figure 2 In the embodiment shown, the limiting structure 5 and the guide member 2 are integrally formed. It is understood that the limiting structure 5 and the guide member 3 of the present application can also be designed as two parts in a split manner. The limiting structure 5 of the heating device of the present application can be supported on the guide member 3 or the mounting seat 2, and the limiting structure 5 can also be fixed to the base of the heating device other than the heating member 4. Figure 6 As shown, the guide member 3 is supported on the heating member 4. In some embodiments, the guide member 3 may also be supported on the mounting base 2, or the guide member 3 may also be supported on the mounting base 2 and the heating member 4. The above connection methods are all within the protection scope of this application.

[0015] like Figure 3As shown, in the heating device of the embodiment of the present application, the guide member 3 is inserted into the heating chamber 11 of the shell 1, so that the guide member 3 and the wall surface of the heating chamber 11 enclose a heating space 12, and then the heating part of the heating element 4 is inserted into the heating space 12, so that the heating part, the shell 1 and the guide member 3 enclose a heating channel 13, and the heating channel 13 surrounds the outer wall of the heating part, and the extension direction of the heating channel 13 is the same as the extension direction of the heating part of the heating element 4. As a result, the contact area between the water flow in the heating channel 13 of the present application and the heating element 4 is large, and the water in the heating channel 13 is fully heated and absorbs heat and heats up quickly, so that the heating efficiency of the heating device is high. The heating device of the present application is an instant heating device.

[0016] During the assembly process of the heating device, the heating element 4 is connected to the mounting seat 2, and then the heating part of the heating element 4 is inserted into the heating cavity 11 of the shell 1. The heating element 4 is usually a slender structure, and the connection contact area between the heating element 4 and the mounting seat 2 is small. When the heating element 4 is installed on the mounting seat 2, the heating element 4 may be deflected relative to the mounting seat 2. The heating element 4 is a slender member, so that the deflection between the end of the heating element 4 away from the mounting seat 2 and the inner wall of the heating cavity 11 and the guide member 3 is large, resulting in uneven gaps in the heating flow channel 13, so that the water in the heating flow channel 13 is heated unevenly, thereby affecting the heating efficiency of the heating device. The gap value of the heating flow channel 13 of the heating device has a gap value range set in the initial design. After the heating part of the heating element 4 is inserted into the heating space 12, the deflection of the heating part of the heating element 4 relative to the shell 1 may cause the gap value set in the initial design to be unable to be guaranteed.

[0017] In order to solve the above problems, the heating device provided in the embodiment of the present application is as follows: Figure 6 As shown, a limiting structure 5 is provided in the heating chamber 11, and the limiting structure 5 is connected to the flow guide 3 or the mounting seat 2. The limiting portion of the limiting structure 5 is arranged relative to the outer peripheral wall of the heating portion, and a limiting matching relationship is formed between the limiting portion and the outer peripheral wall of the heating portion. In this way, during the assembly process of the heating portion of the heating element 4 being inserted into the heating chamber 11, the limiting portion can prevent the heating portion from deflecting in the direction of the limiting portion, ensuring that the relative position relationship between the heating portion and the wall surface of the heating chamber 11 and the flow guide 3 meets the set requirements, and preventing the portion of the heating element 4 inserted into the heating space 12 from deflecting toward the wall surface of the heating chamber 11 or the wall surface of the flow guide 3. The heating device of the present application can ensure that the gap of the heating channel 13 is uniform, so that the water at different positions of the heating channel 13 is heated evenly, and the water in the heating channel 13 absorbs heat and heats up consistently, ensuring the heating efficiency of the heating device.

[0018] It can be understood that the limiting structure 5 of the present application is not limited to Figure 2 and Figure 6The specific structure shown in . In some embodiments of the heating device, the limiting structure 5 of the present application can be configured to have one end connected to the shell 1 or the mounting seat 2, and the limiting portion at the other end extends to the peripheral wall of the heating portion of the heating element 4. In some exemplary embodiments, the limiting structure 5 of the present application can be configured to include an elastic member, one end of the elastic member is fixed to the base of the heating device, and the other end of the elastic member abuts against the peripheral wall of the heating portion of the heating element 4. In some exemplary embodiments, the limiting structure 5 of the present application can be configured to be an annular member, which is sleeved on the peripheral wall of the heating portion of the heating element 4, and the annular member is also fixedly connected to the base of the heating device. The above embodiments can all achieve the purpose of the limiting portion of the limiting structure 5 being arranged relative to the peripheral wall of the heating portion of the heating element 4, preventing the heating portion of the heating element 4 from swinging in the direction of the limiting portion. The above embodiments are all within the protection scope of the present application.

[0019] In an exemplary embodiment, Figure 6 , Fig.13 and Fig.14 As shown, the heating portion includes a heating area 43 and a non-heating area 42 . The non-heating area 42 is arranged close to the first opening 111 , and the limiting portion is arranged outside the outer peripheral wall of the non-heating area 42 .

[0020] Specifically, the non-heating area 42 does not generate heat, and the heating area 43 of the heating element 4 is used to generate heat to heat the water in the heating channel 13 to increase its temperature.

[0021] The non-heating zone 42 and the limiting portion of the embodiment of the present application can be arranged close to one side of the mounting seat 2, so that the limiting portion located on the outer side of the outer peripheral wall of the non-heating zone 42 can prevent the portion of the heating element 4 close to the first opening 111 from being tilted relative to the mounting seat 2, so that the installation orientation of the heating element 4 relative to the connecting structure of the mounting seat 2 is accurate, ensuring that the gap of the flow cross section of the heating channel 13 is uniform.

[0022] A water flow channel connected to the heating flow channel 13 may be formed between the non-heating area 42 and the limiting portion.

[0023] In an exemplary embodiment, the limiting portion is located in at least one direction of above, below, left and right of the outer peripheral wall of the heating portion.

[0024] Specifically, Fig.12 Specific directions of the upper, lower, left, and right sides of the outer peripheral wall of the heating portion are shown in FIG.

[0025] For example, when the limiting portion is located above the peripheral wall of the heating portion, the limiting portion can prevent the heating portion from deflecting upward relative to the housing 1. The limiting portion can also be located in two, three or four directions of the upper, lower, left and right sides of the peripheral wall of the heating portion. The more limiting directions the limiting portion has for the peripheral wall of the heating portion, the more stable the limiting relationship between the heating portion and the limiting structure 5. The specific limiting direction of the limiting portion for the heating portion can be selected according to actual needs.

[0026] In an exemplary embodiment, the limiting portion is located in at least two directions of the upper, lower, left and right sides of the outer peripheral wall of the heating portion, and one of the at least two directions is not opposite to the other direction.

[0027] For example, the limiting portion may be located above and to the left of the outer peripheral wall of the heating portion, with the above and the below being opposite directions, and the above and the left being non-opposite directions.

[0028] exist Fig.12 In the illustrated embodiment of the heating device, the two sets of limit portions are respectively located in three directions: left, right and top of the corresponding heating portion, wherein top and left are non-opposite directions, and top and right are non-opposite directions.

[0029] The heating device of the embodiment of the present application is provided with a limit portion located in two non-opposite directions of the outer peripheral wall of the heating portion. In this way, the limit portion can limit the heating portion from two non-opposite directions, and form a semi-enclosed limit for the heating portion from at least two non-opposite directions, so that the heating portion is not prone to large deflection after being inserted into the heating cavity 11, which is conducive to ensuring that the gap value of the heating flow channel 13 meets the set gap value range.

[0030] In an exemplary embodiment, Figure 6 , Fig. 9 , Figures 11 to 13 As shown, the heating part includes a cylindrical structure, the limiting part includes an arched part 51 , the arched part 51 includes an arcuate concave surface 511 adapted to the cylindrical structure, and the arched part 51 can limit the heating part from swinging in the direction of the arcuate concave surface 511 .

[0031] Specifically, the arched portion 51 is used to limit the outer wall of the heating portion. The structure is simple in design and easy to process, design and assemble. It can be understood that the heating element 4 of the embodiment of the present application can be constructed as follows: Fig.13 The U-shaped heating rod shown may also be constructed into other external structures, all of which are within the protection scope of the present application.

[0032] The connection and cooperation mode between the heating part and the limiting part of the present application can also be set to various connection forms such as snap-fit, elastic part limiting, plug-in, etc., which are all within the protection scope of the present application.

[0033] In an exemplary embodiment, Figure 3 As shown, a first gap 131 is provided between the cavity wall of the heating cavity 11 and the heating part, and a second gap 132 is provided between the flow guide 3 and the heating part. The first gap 131 and the second gap 132 together form a heating flow channel 13 surrounding the outer peripheral wall of the heating part.

[0034] like Fig.12 As shown, the limiting portion includes a first gap control portion, and the first gap control portion is located on one side of the first gap 131 of the heating portion.

[0035] Specifically, the limiting part includes a first gap control part, and the first gap control part is located on one side of the first gap 131 of the heating part, so that the limiting part can ensure that the heating part does not deflect toward the first gap 131, and ensure that the gap value of the first gap 131 is uniform. Since the first gap 131 and the second gap 132 jointly form the heating flow channel 13, the heating part is located between the first gap 131 and the second gap 132, by adjusting the gap value of the first gap 131 to be uniform, the gap value of the second gap 132 can be indirectly ensured to be uniform. Fig.12 In the illustrated embodiment of the heating device, both sides of the first gap 131 and the second gap 132 are provided with partial structures of limiting parts, and the limiting parts can simultaneously ensure that the first gap 131 and the second gap 132 are within the set value range.

[0036] In an exemplary embodiment, Figures 4 to 6 and Fig.16 As shown, the heating device also includes a gap retainer 6, which includes a first end and a second end. The first end is arranged on the shell 1 or the guide member 3, and the second end is supported between the wall surface of the heating chamber 11 and the heating element 4.

[0037] The limiting structure 5 is disposed close to the first opening 111, and the gap retaining member 6 is located at an end of the heating chamber 11 away from the first opening 111; The limiting portion is located in a first direction of the outer peripheral wall of the heating portion, and the second end is located in a second direction of the outer peripheral wall of the heating portion, wherein the second direction at least includes a direction opposite to the first direction, so as to control the gap of the heating channel 13 to be uniform.

[0038] Specifically, Figure 4 and Figure 6 As shown, the gap retaining member 6 and the limiting structure 5 are located at the two ends of the heating part, and the two ends of the heating part are respectively limited and constrained by the limiting structure 5 and the gap retaining member 6 to prevent the heating part from being skewed relative to the shell 1 and the guide member 3 after being inserted into the heating chamber 11, thereby ensuring that the gap of the heating channel 13 is uniform and that the gap value of the heating channel 13 is within the set gap value range.

[0039] Figure 6In the illustrated heating device embodiment, after the flow guide 3, the heating element 4 and the mounting seat 2 are mounted together, the limiting structure 5 is mounted to the end of the heating element 4 close to the mounting seat 2, the gap retaining member 6 is clamped to the ends of the heating element 4 and the flow guide 3 away from the mounting seat 2, and then the flow guide 3 and the heating element 4 are inserted into the heating chamber 11 together, and the mounting seat 2 blocks the first opening 111 of the shell 1. Since the limiting structure 5 and the gap retaining member 6 respectively limit the two ends of the heating element 4, even if the heating part is deflected relative to the shell 1, the limiting structure 5 and the gap retaining member 6 can make correction adjustments to the heating part, so the relative position of the heating part relative to the inner wall of the shell 1 and the flow guide 3 meets the set requirements, and the gap of the heating channel 13 is uniform.

[0040] Among them, the limiting portion is located in the first direction of the outer peripheral wall of the heating portion, and the second end is located in the second direction of the outer peripheral wall of the heating portion, and the second direction at least includes a direction opposite to the first direction, so that the outer peripheral walls of the heating portion at one end close to the first opening 111 and the one end away from the first opening 111 are respectively constrained by forces in opposite directions, which is beneficial to ensuring the stable position of the heating portion relative to the inner wall of the shell 1, and to ensuring the uniformity of the gap value of the heating channel 13.

[0041] In some embodiments, the gap retainer 6 is configured to be made of a bent elastic filament. In this way, the relative positions of the heating part, the housing 1 and the flow guide 3 can be adjusted through the elastic deformation of the gap retainer 6 to ensure that the gap of the heating channel 13 is uniform.

[0042] In an exemplary embodiment, Figure 8 , Fig. 9 and Figures 11 to 14 As shown, the heating element 4 is arranged to be bent and extended, the number of the non-heating zones 42 is two, the number of the arched portions 51 is two, and the two arched portions 51 correspond one to one to the two non-heating zones 42.

[0043] Specifically, the two arched portions 51 are respectively surrounded on the outer peripheral wall of the corresponding non-heating zone 42, so that the arched portion 51 can limit the non-heating zone 42. The structure is simple in design and easy to process and assemble. In addition, the two arched portions 51 are used to limit the two non-heating zones 42 respectively, so that both ends of the heating portion are limited, and the position of the heating element 4 in the heating chamber 11 is stable and not prone to deflection.

[0044] It can be understood that the cross section of the heating element 4 perpendicular to its length direction can be set to various shapes such as circular, rectangular, polygonal, etc., all of which are within the protection scope of the present application.

[0045] In an exemplary embodiment, Figure 7 and Fig. 9As shown, a clamping portion 19 is provided on the side wall of the heating chamber 11 , and a clamping fitting portion 514 is provided on the side of the arched portion 51 away from the flow guide 3 , and the clamping portion 19 and the clamping fitting portion 514 are clamped together.

[0046] Specifically, a snap-fit ​​connection structure is used to support the limiting portion on the housing 1 , which makes it easy to disassemble and assemble the limiting structure 5 .

[0047] In an exemplary embodiment, Fig.12 As shown, there is a gap between the arc-shaped concave surface 511 and the outer peripheral wall of the heating portion.

[0048] Specifically, a gap is provided between the arc-shaped concave surface 511 and the outer peripheral wall of the heating part, so that when the heating part is inserted into the heating chamber 11, even if the connection structure between the heating part and the mounting seat 2 is skewed, the connection orientation between the heating part and the mounting seat 2 can be adjusted to a certain extent. In this way, the relative position of the heating part relative to the wall surface of the heating chamber 11 and the wall surface of the flow guide 3 can be adjusted to ensure that the gap value of the heating flow channel 13 meets the set value range.

[0049] In an exemplary embodiment, Figures 9 to 12 As shown, the two arched portions 51 are respectively recorded as a first arched portion 512 and a second arched portion 513; Figure 7 As shown, the housing 1 is provided with a water inlet 14 and a water outlet 15 which are communicated with the heating chamber 11 .

[0050] The first arched portion 512 is provided with a water inlet channel 5121, the water inlet end of the water inlet channel 5121 is connected to the water inlet 14, and the arc-shaped concave surface 511 of the first arched portion 512 is concavely provided with a first drainage groove 5122 connected to the water outlet end of the water inlet channel 5121, and the first drainage groove 5122 is connected to the heating channel 13.

[0051] The second arched portion 513 is provided with a water outlet channel 5131, the water outlet end of the water outlet channel 5131 is configured to be connected to the water outlet 15, and a second drainage groove 5132 connected to the water inlet end of the water outlet channel 5131 is recessed on the arc-shaped concave surface 511 of the second arched portion 513, and the second drainage groove 5132 is connected to the heating channel 13.

[0052] Specifically, the water flow path of the heating device of the embodiment of the present application is as follows: water flows from the water inlet 14 into the heating chamber 11, first into the water inlet channel 5121, then into the first drainage groove 5122, then into the heating channel 13, flows along the heating channel 13, flows into the second drainage groove 5132, then flows into the water outlet channel 5131, and finally flows out from the water outlet 15. In an exemplary embodiment, as Figure 7As shown, the shell 1 is provided with a heating chamber 11 and a mixing chamber 17. The mixing chamber 17 is connected to the heating chamber 11 through an intermediate flow channel 18. Water flowing into the water outlet channel 5131 first flows into the intermediate flow channel 18, then flows into the mixing chamber 17, and finally flows out from the water outlet 15.

[0053] Among them, Fig.12 As shown, a first drainage groove 5122 and a second drainage groove 5132 are provided on the arch portion 51, so that the flow cross-section area of ​​the water flow channel between the arch portion 51 and the outer peripheral wall of the non-heating area 42 becomes larger, so that the water flow rate and flow velocity between the arch portion 51 and the outer peripheral wall of the heating portion are increased, which is beneficial to improving the heating efficiency of the heating device.

[0054] In an exemplary embodiment, Fig.10 As shown, the water inlet end of the water outlet channel 5131 is located at the upper part of the heating element, and a recessed step 5133 is also recessed on the arc-shaped concave surface 511 of the second arched portion 513 , and the recessed step 5133 is connected to the second drainage groove 5132 .

[0055] Specifically, the step 5133 is used to avoid water flow, so that the water flow rate and flow speed between the arch portion 51 and the outer peripheral wall of the non-heating area 42 are increased.

[0056] When the water in the heating chamber 11 is heated by the heating element 4, bubbles are generated, and the bubbles have a low density and tend to float upward. Fig.10 and Fig.12 As shown, the water inlet ends of the second drainage groove 5132 and the water outlet channel 5131 are both located at the upper part of the heating element 4, so that when the bubbles mixed in the water flow of the heating channel 13 flow to the vicinity of the water outlet channel 5131, the bubbles float to the upper part of the water flow and can be smoothly discharged from the heating chamber 11 through the second drainage groove 5132 and the water outlet channel 5131. This structure is conducive to the bubbles mixed in the water of the heating chamber 11 to be discharged from the heating chamber 11.

[0057] In an exemplary embodiment, Figures 3 to 5 As shown, the guide member 3 is provided with an air cavity 31, which is connected to the heating channel 13 through a flow gap 16; by adjusting the position of the limiting structure 5 relative to the shell 1, the flow cross-section of the heating channel 13 can be changed and the fluid flow in the flow gap 16 can be controlled.

[0058] Specifically, by adjusting the position of the limiting structure 5, the gap of the flow cross section of the heating flow channel 13 can be changed, and the position of the heating part in the heating space 12 can be changed, so that the water pressure in the heating flow channel 13 fluctuates and the capacity of the heating flow channel 13 changes, so that fluid flow is generated between the heating flow channel 13 and the air cavity 31 through the flow gap 16. The flow of fluid in the flow gap 16 (the gas in the air cavity 31 flows to one side of the heating flow channel 13, or the water on one side of the heating flow channel 13 flows to one side of the air cavity 31) can balance the water pressure fluctuation and water temperature fluctuation in the heating flow channel 13.

[0059] The air cavity 31 of the flow guide 3 is filled with gas, and the air cavity 31 is connected to the heating channel 13 through the connecting gap 16. When the water pressure and flow rate in the heating channel 13 increase, the water in the heating channel 13 will flow to the side of the air cavity 31 through the connecting gap 16, thereby compressing the gas in the air cavity 31, so that the gas with increased air pressure in the air cavity 31 has a stabilizing effect on the heating channel 13. When the water pressure and flow rate in the heating channel 13 decrease, the gas in the air cavity 31 will diffuse to the side of the heating channel 13 through the connecting gap 16, and the volume of the gas in the air cavity 31 will increase and the air pressure will decrease, thereby stabilizing the water pressure of the water flow in the heating channel 13, maintaining the water pressure balance in the heating channel 13 and ensuring the stability of the water discharge of the heating device. At the same time, the gas in the air cavity 31 and the water flow in the heating channel 13 also exchange heat through the flow gap 16, thereby stabilizing the water temperature of the water flow in the heating channel 13.

[0060] It is worth noting that since the height of the connecting gap 16 is small and the flow rate of water or gas entering the connecting gap 16 is small, the connecting gap 16 will not affect the main flow rate in the heating channel 13, and a large amount of water in the heating channel 13 will not enter the connecting gap 16 and the air cavity 31.

[0061] In an exemplary embodiment, Figure 7 and Fig.10 As shown, the shell 1 is also provided with a mixing chamber 17, and the water outlet 15 is provided in the mixing chamber 17. The mixing chamber 17 is located on the upper side of the heating chamber 11. The shell 31 is provided with a water outlet end connecting the water outlet channel 5131 and the middle channel 18 of the mixing chamber 17. The water outlet end of the water outlet channel 5131 is connected with the water outlet 15 through the middle channel 18 and the mixing chamber 17.

[0062] Specifically, water is heated in the heating chamber 11, high-temperature water tends to float, and low-temperature water tends to sink. There is a water temperature stratification phenomenon in the heating flow channel 13 of the heating chamber 11, and the water flow temperature in the heating chamber 11 is uneven. The water in the heating chamber 11 flows into the mixing chamber 17 for further mixing, so that the water temperature is mixed more evenly, so that the temperature of the water discharged from the heating device is consistent, and the user experience is good.

[0063] In an exemplary embodiment, Figure 6 and Figures 11 to 14 As shown, the heating element 4 includes two connection ends 41 , the two connection ends 41 are supported on the mounting seat 2 , and the heating portion extends between the two connection ends 41 .

[0064] The limiting structure 5 includes two groups of limiting parts, and the two groups of limiting parts are respectively arranged at two end positions of the heating part close to the wiring end.

[0065] Specifically, the connection end 41 of the heating element 4 is used to connect to the mounting seat 2, and to lead the wire to the outside of the housing 1 to connect the circuit. The two ends of the heating part close to the two connection ends 41 are limited by the two groups of limit parts of the limit structure 5 to prevent the end of the heating element 4 close to the mounting seat 2 from being deflected relative to the housing 1, ensuring that the gap of the flow cross section of the heating flow channel 13 is uniform.

[0066] The two sets of limiting parts of the present application can be used together with the gap retaining member 6 mentioned above to ensure that the gap of the heating flow channel 13 is uniform.

[0067] In an exemplary embodiment, Figures 13 to 15 As shown, the mounting base 2 is provided with a positioning countersunk hole 21, the wiring end 41 is inserted into the positioning countersunk hole 21, and there is a gap 22 between the outer peripheral wall of the wiring end 41 and the side wall of the positioning countersunk hole 21 to allow the heating part to swing relative to the shell 1 during the process of being inserted into the heating chamber 11.

[0068] Specifically, there is a gap 22 between the outer peripheral wall of the terminal end 41 and the side wall of the positioning countersunk hole 21 to allow the heating part to swing relative to the shell 1 during the insertion into the heating chamber 11, so that the angular orientation of the heating element 4 relative to the mounting seat 2 can be adjusted to ensure that after the heating element 4 is inserted into the heating space 12, the heating element 4 is limited and constrained by the gap retaining member 6 and the limiting structure 5 mentioned above, so that the gap value of the flow cross section of the heating channel 13 is uniform. Fig.13 The arrow direction in FIG. 4 indicates the moving direction of the heating element 4 during the assembly process.

[0069] In an exemplary embodiment, Fig.15 As shown, a sealing step 23 is provided at the opening of the positioning counterbore 21 , and the heating device further comprises a sealing member 7 ; the sealing member 7 is limited at the sealing step 23 and is tightly matched with the outer side wall of the wiring end 41 .

[0070] The limiting structure 5 also cooperates with the sealing member 7 and the mounting seat 2 to prevent the sealing member 7 from escaping from the sealing step 23 .

[0071] Specifically, the sealing member 7 is used to ensure the sealing of the heating chamber 11 enclosed by the mounting seat 2 and the shell 1 to prevent water leakage in the heating chamber 11 .

[0072] When the limiting structure 5 is provided with an arched portion 51 , the diameter of the arc-shaped concave surface of the arched portion 51 is smaller than the diameter of the outer ring of the sealing member 7 , so that the limiting structure 5 can prevent the sealing member 7 from escaping from the sealing step 23 .

[0073] In an exemplary embodiment, Figures 8 to 10 and Fig.17 As shown, the limiting structure 5 and the flow guide member 3 are arranged as an integrated structure.

[0074] Specifically, the limiting structure 5 and the guide member 3 are configured as an integrated structure, which can reduce the number of parts of the heating device. It is understandable that the limiting structure 5 and the guide member 3 can also be configured as a split design, or the limiting structure 5 can be located on the mounting seat 2.

[0075] In an exemplary embodiment, Fig.13 and Fig.17 As shown, the heating element 4 is a bent and extended strip structure so that the heating element 4 has an escape space 44, the bottom contour 32 of the guide member 3 is smaller than the escape space 44, and the upper contour 33 is larger than the escape space 44, so that the guide member 3 can move downward from the position above the heating element 4 to be inserted into the escape space 44 and supported by the heating element 4.

[0076] The limiting structure 5 includes an arched portion 51 , a curved concave surface 511 of the arched portion 51 is connected to the upper contour 33 of the flow guide 3 , and an opening of the curved concave surface 511 of the arched portion 51 faces the bottom contour 32 of the flow guide 3 .

[0077] Specifically, Fig.17 The arrow direction in the figure indicates the moving direction of the guide member 3. The guide member 3 moves downward from the upper position of the heating member 4, is inserted into the avoidance space 44 and supported by the heating member 4, so that the guide member 3 can be hung on the heating member 4 through the arched parts 51 on both sides. This structural design enables the heating member 4, the guide member 3 and the limiting structure 5 to achieve quick disassembly and assembly operations.

[0078] The installation process of the heating device of one embodiment of the present application is as follows: Fig.13 As shown, the terminal end 41 of the heating element 4 is inserted into the positioning countersunk hole 21 of the mounting seat 2, and the sealing member 7 is installed in the sealing step 23 at the opening position of the positioning countersunk hole 21 to form Fig.14 The upper contour 33 of the guide member 3 is connected to the two arched portions 51 on both sides, and then Fig.17 As shown in the figure, the guide member 3 is moved downward from the top of the heating member 4 and inserted into the avoidance space 44, and the arc-shaped concave surfaces 511 of the two arched portions 51 respectively surround the outer side wall of the heating member 4, and the two wall surfaces of the two arched portions 51 opposite to the mounting seat 2 respectively abut against the mounting seat 2 and the sealing member 7 to prevent the sealing member 7 from falling out of the sealing step 23, thereby forming Fig.11 Assemblies as shown. Figure 6 As shown, the gap retaining member 6 is arranged on the side of both the heating member 4 and the flow guide member 3 away from the mounting seat 2, so that both the gap retaining member 6 and the limiting structure 5 limit the heating member 4. Figure 6 The arrows indicate the moving directions of the heating part and the guide member 3 when both are inserted into the heating space 12. After both the heating part and the guide member 3 are inserted into the heating space 12, the mounting seat 2 blocks the first opening 111 of the housing 1 to form Figures 3 to 5 If the heating part is deflected relative to the shell 1 and the flow guide 3 during the insertion of the heating part into the heating space 12, both the gap retainer 6 and the limiting structure 5 can limit the heating part and adjust the position of the heating part relative to the inner wall of the shell 1 and the heating element 4 to ensure that the gap value of the flow cross section of the heating flow channel 13 is uniform.
