Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drinking water equipment, in particular to a cover member, a heating element assembly and a drinking water equipment. BACKGROUND

[0002] At present, household drinking water equipment such as water purifying machines and pipeline machines basically adopt instant heating design. When the user takes water, the machine instantly heats through the heating element, and the machine does not need to heat and store hot water for a long time, which reduces energy loss and improves user experience.

[0003] As one of the core components of the whole machine, the main function of the heating element is to convert electrical energy into heat energy, so as to heat water through heat energy. In order to realize large flow of hot water, the current household drinking water equipment basically provides a very high power for the heating pipe, such as 2100W, and directly uses 220V voltage for power supply.

[0004] As a long strip structure component, the heating element is generally vertically installed in the drinking water equipment due to space limitation, and the power supply line is connected in the middle. After long-term use of the household drinking water equipment, the seal at the inlet and outlet of the heating element may fail. If the seal at the outlet or inlet of the top of the heating element fails, the leaked water is easy to drop on the power line terminal, which not only affects the normal use of the drinking water equipment, but also may cause short circuit, leakage and other safety hazards. UTILITY MODEL CONTENT

[0005] Therefore, it is necessary to provide a cover member, a heating element assembly and a drinking water equipment to solve the problem that the leaked water is easy to drop on the power line terminal when the seal at the outlet or inlet of the top of the heating element fails.

[0006] A cover member, comprising:

[0007] a main body structure;

[0008] a pipeline structure protruding in a vertical direction on the main body structure and having a water inlet at one end away from the main body structure;

[0009] wherein the cover member has a water guide opening and a drain opening connected with the water guide opening, the water guide opening is located below the water inlet, the plane where the water guide opening is located intersects with the vertical direction, and at least part of the side wall of the pipeline structure extends from the water inlet to the water guide opening.

[0010] In one of the embodiments, the water guide opening is located on one side of the pipeline structure in a first direction, and the first direction intersects with the vertical direction.

[0011] In one of the embodiments, the cover member further comprises a surrounding structure disposed on the main body structure, the surrounding structure is protruded from the main body structure along the vertical direction,

[0012] The surrounding structure is in a ring shape without head-to-tail connection, the head end and the tail end of the surrounding structure are spaced apart along the second direction and are both connected to the side wall of the pipe structure, and the surrounding structure and the pipe structure jointly form the water guide opening.

[0013] The first direction, the second direction and the vertical direction are intersected with each other and are not coplanar.

[0014] In one of the embodiments, the surrounding structure comprises a surrounding wall and a connecting wall, the surrounding wall comprises two surrounding walls which are spaced apart along the second direction on the main body structure, and each of the surrounding walls is connected to the pipe structure at one end along the first direction and is connected to the connecting wall at the other end along the first direction.

[0015] In one of the embodiments, the main body structure has a plurality of stepped surfaces arranged in a stepped manner along the first direction, all the stepped surfaces are located between the two surrounding walls, and the height of the stepped surfaces gradually decreases in the direction away from the pipe structure, and the drain opening is arranged on the stepped surface at the lowest point.

[0016] In one of the embodiments, the side wall of the pipe structure is provided with a mounting groove, and the mounting groove is arranged around the pipe structure in the circumferential direction.

[0017] In one of the embodiments, the pipe structure is further provided with a temperature measuring hole, and the temperature measuring hole is in communication with the water guide opening.

[0018] In one of the embodiments, the temperature measuring hole is located in the water guide opening.

[0019] A heating body assembly comprising a heating body and a cover member as described in any one of the embodiments, the cover member is arranged on the heating body;

[0020] The heating body has a heating flow channel, and the water guide opening is in communication with the heating flow channel.

[0021] In one of the embodiments, the heating body assembly further comprises a wire structure, and the wire structure is connected to the heating body.

[0022] The water guide opening is located on one side of the pipe structure along the first direction, the first direction intersects with the vertical direction, the wire structure is located on the side of the heating body facing the water guide opening, and the wire structure is located below the drain opening.

[0023] In one embodiment, the heating element assembly further includes a seal that is fitted onto the pipe structure.

[0024] In one embodiment, the pipe structure is further provided with a temperature measuring hole, which is connected to the water inlet;

[0025] The heating element assembly also includes a temperature sensing element, which is disposed at the temperature measuring hole.

The limiting structure is capable of abutting at least one end of the retaining wall in a first direction and / or a second direction, wherein the first direction, the second direction, and the vertical direction intersect each other and are not coplanar.

[0028] In the aforementioned cover component, if the water inlet leaks, the leaking water will flow downwards along the side wall of the pipe structure under the influence of gravity. Since the plane of the guide port is not parallel to the vertical direction and is located below the water inlet, the leaking water, as it moves from the water inlet to the side wall of the guide port, will be guided by the side wall to flow into the guide port and finally discharged through the drain outlet. In this way, the cover component effectively guides the leaking water from the water inlet, allowing it to drain to a designated location. This prevents the leaking water from moving irregularly along the surface of the cover component, thus avoiding dripping onto the internal electrical components of the drinking water equipment. This ensures the normal operation of the drinking water equipment and reduces safety hazards such as short circuits and electrical leaks. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0044] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium.

[0047] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0048] See Figure 1 and Figure 2 , Figure 1 A schematic diagram of a portion of the structure of a drinking water device according to an embodiment of this application is shown. Figure 2A cross-sectional schematic diagram of a drinking water device according to an embodiment of this application is shown. This drinking water device, as provided in this embodiment, can be a water purifier, water dispenser, or other device capable of outputting hot water. The drinking water device includes a water tank 60, a heating element assembly, and a water outlet assembly. The heating element assembly is interconnected with both the water tank 60 and the water outlet assembly, allowing drinking water in the water tank 60 to pass through the heating element assembly into the water outlet assembly, and finally be output to the user through the water outlet assembly to meet the user's drinking water needs.

[0049] The heating element assembly includes a heating element body 50 and a cover 10. The heating element body 50 has a heating channel 58 and an inlet 61 and an outlet 62, both connected to the heating channel 58. The inlet 61 of the heating element body 50 is connected to a water tank 60, allowing drinking water in the water tank 60 to enter the heating channel 58 through the inlet 61. The drinking water in the heating channel 58 is heated by the heating element body 50, thereby raising the temperature to the user's desired temperature.

[0050] Furthermore, the cover 10 is placed over the water outlet 62 of the heating element body 50 to seal the end face of the heating element body 50 with the water outlet 62. The cover 10 also has a water inlet 12, which is connected to the water outlet 62 and can also be connected to the water outlet assembly. Drinking water in the heating channel 58 can flow into the water outlet assembly through the water outlet 62 and the water inlet 12, and finally, the heated water is supplied to the user through the water outlet assembly, thereby meeting the user's need for hot water.

[0051] In actual use, the water inlet 12 can be directly connected to the water outlet assembly, or indirectly connected to the water outlet assembly through water pipes or other connectors. Regardless of whether the water inlet 12 is directly or indirectly connected to the water outlet assembly, if the silicone seal 52 on the heating element assembly fails due to aging from prolonged use or encountering other non-standard usage conditions such as high temperature, high humidity, abnormal water quality, external impact, or misalignment, water leakage may occur at the connection point between the water inlet 12 and other components. The water leaking from the water inlet 12 may drip onto electrical components such as power cord terminal connectors, thus affecting the normal use of the drinking water equipment and potentially causing safety hazards such as short circuits and electrical leakage.

[0052] For this purpose, please refer to Figure 3 and Figure 4The cover component 10 includes a main structure 11 and a pipe structure 20. The main structure 11 is disposed on the end face of the heating element body 50 where the outlet 62 is provided, and the end face of the heating element body 50 is sealed by the main structure 11. Further, the cover component 10 also includes a pipe structure 20, which protrudes vertically from the main structure 11 and has a water inlet 12 at the end away from the main structure 11. When the main structure 11 is sealed on the end face of the heating element body 50, the water inlet 12 is connected to the outlet 62.

[0053] The cover 10 also includes a water inlet 21 and a drain outlet 22 connected to the water inlet 21. The water inlet 21 is located below the water outlet 12, and the plane of the water inlet 21 intersects the vertical direction X. At least a portion of the sidewall 25 of the pipe structure 20 extends from the water outlet 12 to the water inlet 21. In actual use, if the water outlet 12 leaks, the leaking water will flow along the sidewall 25 of the pipe structure 20 and, guided by the sidewall 25, will flow into the water inlet 21 and finally be discharged through the drain outlet 22.

[0054] Specifically, if water inlet 12 leaks, the leaking water will flow downwards along the side wall 25 of the pipe structure 20 under the influence of gravity. Since the plane of the guide port 21 is not parallel to the vertical direction X, and the guide port 21 is located below the water inlet 12, when the water extends from the water inlet 12 to the side wall 25 of the guide port 21, the leaking water will flow into the guide port 21 under the guidance of the side wall 25, and finally be discharged through the drain port 22. In this way, the cover 10 can guide the leaking water from the water inlet 12, allowing the leaking water to be discharged to a designated location through the drain port 22. This prevents the leaking water from moving irregularly along the surface of the cover 10, causing the leaking water to drip onto the internal electrical components of the drinking water equipment, ensuring the normal use of the drinking water equipment, and reducing safety hazards such as short circuits and leakage.

[0055] It is understandable that, in order to ensure that water from the inlet 21 can flow out from the outlet 22, the outlet 22 needs to be located below the inlet 21 in the vertical direction X. Furthermore, in some other embodiments, the cover 10 can also be used to cover the end face of the heating element body having the inlet 61, and in this embodiment, the water inlet 12 on the cover 10 is connected to the inlet 61 of the heating element body.

[0056] The phrase "at least a portion of the sidewall 25 of the pipe structure 20 extends from the inlet 12 to the outlet 21" means that all the sidewalls 25 of the pipe structure 20 can extend to the outlet 21, or only a portion of the sidewalls 25 can extend to the outlet 21. When all the sidewalls 25 of the pipe structure 20 extend to the outlet 21, the outlet 21 is arranged circumferentially around the pipe structure 20, so that most of the water leaking from the inlet 12 can enter the outlet 21 along the sidewalls 25 of the pipe structure 20.

[0057] The circumferential arrangement of the water inlet 21 around the pipe structure 20 would increase the volume of the cover 10, which is not conducive to reducing the volume of the drinking water device. Therefore, in some embodiments of this application, the water inlet 21 is located on one side of the pipe structure 20 in the first direction Y, which intersects the vertical direction X. That is, only one side wall 25 of the pipe structure 20 extends to the water inlet 21, while the other side wall 25 is avoided by the water inlet 21.

[0058] In this way, the electrical components that need to be protected in the drinking water equipment can be placed on the side of the cover 10 with the water inlet 21. The water leaking from the water inlet 12 will move along the side wall 25 of the pipe structure 20 and form two parts. The water on the side wall 25 facing the water inlet 21 will enter the water inlet 21 and finally be discharged from the drain outlet 22, thus preventing it from falling into the electrical components below the water inlet 21.

[0059] Water on the side wall 25 away from the water inlet 21 will drip from the side of the cover 10 away from the water inlet 21. Since the electrical components that the drinking water device needs to protect are all located on the side of the cover 10 facing the water inlet 21, even if water on the side wall 25 away from the water inlet 21 drips from the cover 10, it will not fall on the electrical components and will not cause damage to the electrical components.

[0060] In one specific embodiment, the heating element assembly further includes a wire structure 51, which is connected to the heating element body 50 to enable electrical connection between the heating element body 50 and other electrical devices such as the power supply of the water dispenser. Specifically, the wire structure 51 includes a wire body 56 and a terminal block 57. The wire body 56 is connected to the heating element body 50 through the terminal block 57. The wire body 56 is used to transmit current or electrical signals, and the terminal block 57 is used to enable quick connection between the wire body 56 and the heating element body 50.

[0061] The wire structure 51 is located on the side of the heating element body 50 facing the water inlet 21, and is positioned below the drain outlet 22. Thus, a portion of the water leaking from the water inlet 12 will eventually drain out through the drain outlet 22 via the water inlet 21. Because the wire structure 51 is positioned below the drain outlet 22, water entering the water inlet 21 will not drip onto the wire structure 51. The remaining water that does not enter the water inlet 21 will drip from the side of the cover 10 away from the water inlet 21. Since the wire structure 51 is located on the side of the heating element body 50 facing the water inlet 21, the remaining water will also not drip onto the wire structure 51, ensuring its normal operation.

[0062] In some embodiments of this application, see [reference] Figure 5 and Figure 6 The cover 10 also includes a enclosure structure 30 disposed on the main structure 11. The enclosure structure 30 protrudes from the main structure 11 in the vertical direction X. The enclosure structure 30 is a ring structure with no connection between the beginning and the end. It should be noted that the ring structure is not limited to a circle, but can be a square, hexagon or other irregular shape.

[0063] The first and last ends of the enclosure structure 30 are arranged at intervals along the second direction Z. Both the first and last ends of the enclosure structure 30 are connected to the side wall 25 of the pipe structure 20, so that the enclosure structure 30 and the pipe structure 20 are jointly enclosed to form the water guide 21.

[0064] Thus, the pipe structure 20 is surrounded on one side of the first direction Y by the enclosure structure 30, and since the first and last ends of the enclosure structure 30 are spaced apart along the second direction Z, at least part of the sidewall 25 of the pipe structure 20 is located inside the enclosure structure 30, so that after the pipe structure 20 and the enclosure structure 30 form the water guide 21, part of the inner wall of the pipe structure 20 can extend to the water guide 21.

[0065] Furthermore, the water leaking from the water inlet 12 is guided into the water outlet 21 by the side wall 25, and is blocked by the enclosure structure 30 within the annular structure formed by the enclosure structure 30, preventing water from dripping from the cover 10 and allowing it to flow out from the drain outlet 22, thus achieving the effect of draining the leaked water from the designated location.

[0066] In some specific embodiments, the enclosure structure 30 includes enclosure walls 31 and connecting walls 32 that protrude from the main structure 11 in the vertical direction X. There are two enclosure walls 31, which are arranged at intervals in the second direction Z on the main structure 11. Each enclosure wall 31 is connected to the pipe structure 20 at one end in the first direction Y, and the other end of each enclosure wall 31 in the first direction Y is connected to the connecting wall 32.

[0067] Thus, the enclosure wall 31 and the connecting wall 32 form a ring structure that is not connected end to end. This ring structure is a square structure, which blocks the water flowing into the water inlet 21 through the enclosure wall 31 and the connecting wall 32, thereby preventing water from leaking from the side of the cover 10 with the water inlet 21.

[0068] In some specific embodiments, the main structure 11 has multiple stepped surfaces 13 arranged in a stepped manner along the first direction Y. All stepped surfaces 13 are located between two enclosure walls 31. In the direction away from the pipe structure 20, the height of the stepped surfaces 13 gradually decreases, and a drain outlet 22 is provided on the stepped surface 13 at the lowest point. In this way, the water entering the water inlet 21 is gradually guided by the multiple stepped surfaces 13, so that the water flow finally exits from the drain outlet 22. By setting the main structure 11 in a stepped shape, the overall volume of the cover 10 can be reduced, thereby making the installation of the components inside the drinking water device more compact, and further reducing the volume of the drinking water device.

[0069] Specifically, the main structure 11 includes a first stepped surface 131 and a second stepped surface 132. The first stepped surface 131 is located above the second stepped surface 132. The connecting wall 32 protrudes from the second stepped surface 132, and the height of the connecting wall 32 protruding from the first stepped surface 131 is the same as the height of the panel wall protruding from the first stepped surface 131. That is, the height of the connecting wall 32 does not need to be the same as the height of the panel wall; it only needs to be a certain height higher than the second stepped surface 132, thereby reducing the space occupied by the connecting wall 32 and reducing the overall volume occupied by the cover component 10.

[0070] In one specific embodiment, the drinking water device further includes a limiting structure 55, which can abut against one or both ends of the enclosure wall 31 in the first direction Y, thereby limiting the position of the enclosure wall 31. When the heating element body is installed in the vertical direction X, limiting the position of the enclosure wall 31 can prevent the installation of the heating element body from tilting in the first direction Y. It is understood that in some other embodiments, the limiting structure 55 can abut against one or both ends of the enclosure wall 31 in the second direction Z, thereby preventing the installation of the heating element body from tilting in the second direction Z.

[0071] In some embodiments of this application, the heating element assembly further includes a sealing element 52, which is sleeved on the pipe structure 20 so that when the pipe structure 20 is inserted into the connection hole of other components of the drinking water device, the sealing element 52 can seal the gap between the pipe structure 20 and the inner wall of the connection hole, ensuring that the drinking water in the water inlet 12 can be normally input into the connection hole.

[0072] To facilitate the installation of the seal 52, an installation groove 23 is provided on the side wall 25 of the pipe structure 20. The installation groove 23 is arranged circumferentially around the pipe structure 20. When the seal 52 is fitted into the connection hole, part of the seal 52 is located within the installation groove 23, thereby limiting the installation of the seal 52 and preventing it from being pushed out after installation. When assembling the seal 52, it can be pre-installed on the pipe structure 20 before assembly. During disassembly, the sealing groove ensures that the seal 52 can be removed along with the cover 10, improving disassembly and assembly efficiency.

[0073] In some embodiments of this application, a temperature measuring hole 24 is provided on the pipe structure 20, and the temperature measuring hole 24 is connected to the water inlet 12. The heating element assembly also includes a temperature sensing element 53, which is disposed in the temperature measuring hole 24. In this way, the drinking water flowing out from the heating element body will not only pass through the water inlet 12, but also enter the temperature measuring hole 24 and be measured by the temperature sensing element 53 in the temperature measuring hole 24.

[0074] Specifically, the temperature sensor 53 is fixed to the pipe structure 20 with two screws. The temperature sensor 53 monitors the water temperature at the outlet 62 of the heating element body 50 in real time, allowing the system to adjust the overall power in real time to prevent excessive power from the heating element body 50, which could cause the water to boil inside the pipe and result in abnormal noise. Furthermore, the water temperature measured by the temperature sensor 53 is the temperature of the water fully heated by the heating element body 50, providing a more accurate reference for adjusting the overall heating power. Simultaneously, placing the temperature sensor 53 on the cover 10 avoids the need for openings in the stainless steel pipe of the heating element body 50, reducing production costs. Moreover, since the heating element body is a high-voltage circuit while the temperature sensor 53 is a 5V low-voltage component, the influence of high voltage on low voltage is avoided.

[0075] Furthermore, the temperature measuring hole 24 is located inside the water inlet 21. In this way, when water leaks at the temperature measuring hole 24, the leaked water will also flow out from the drain outlet 22 and will not flow irregularly along the outer wall of the cover 10, thus avoiding affecting the normal operation of electrical equipment such as the wire structure 51.

[0076] In some embodiments of this application, in order to fix the cover 10 to the heating element body 50, a plurality of screw holes 14 are also provided on the cover 10. The heating element assembly includes a plurality of fixing screws 54, and the plurality of fixing screws 54 pass through the screw holes 14 to fix the cover 10 to the heating element body 50.

[0077] The aforementioned cover component 10 has at least the following advantages:

[0078] If water leaks from inlet 12, the leaking water will flow downwards along the side wall 25 of the pipe structure 20 under the influence of gravity. Since the plane of guide port 21 is not parallel to the vertical direction X, and guide port 21 is located below inlet 12, as water moves from inlet 12 to the side wall 25 of guide port 21, the leaking water will be guided by the side wall 25 into guide port 21, and finally discharged through drain port 22. Thus, the cover 10 guides the leaking water from inlet 12, allowing it to drain to a designated location through drain port 22. This prevents the leaking water from moving irregularly along the surface of cover 10, which could cause water droplets to fall onto the internal electrical components of the drinking water equipment, ensuring normal operation and reducing safety hazards such as short circuits and electrical leaks.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
