Description

Technical Field

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

[0002] At present, household drinking water equipment, such as water purifiers and pipeline machines, basically adopts instant heating design. When users take water, the machine heats it instantly through the heating element, and heats it as needed. There is no need to store hot water for long-term heating and heat preservation inside the machine, 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 thermal energy, thereby heating water through thermal energy. In order to achieve a large flow of hot water, current household drinking water purification equipment is basically equipped with extremely high power heating tubes, such as 2100W, and directly powered by 220V voltage.

[0004] As a long strip structural component, the heating element is generally installed vertically in drinking water equipment due to space limitations, with a power cord in the middle. After long-term use of the household drinking water equipment, the seals at the water inlet and outlet of the heating element may fail. If the seal at the water outlet or water inlet on the top of the heating element fails, the leaked water can easily drip onto the power cord terminal connector, which will not only affect the normal use of the drinking water equipment, but may also cause safety hazards such as short circuits and leakage. Summary of the invention

[0005] Based on this, it is necessary to provide a cover body, a heating element assembly and a drinking water device to address the problem that when the seal at the water outlet or water inlet on the top of the heating element fails, the leaked water can easily drip onto the terminal connector of the power cord.

[0017] In one of the embodiments, the cover body also includes a pipeline structure and a temperature measuring hole, and the temperature measuring hole is connected to the water outlet.

[0018] In one embodiment, the temperature measuring hole is located in the water guide port.

[0019] A heating element assembly, comprising a heating element body and a cover element as described in any one of the above items, wherein the cover element is arranged on the heating element body;

[0023] In one of the embodiments, the heating element assembly further includes a sealing member, and the sealing member is sleeved on the pipe structure.

[0048] See also Figure 1 and Figure 2 , Figure 1 A schematic diagram showing a partial structure of a drinking water device in an embodiment of the present application is shown. Figure 2The schematic cross-sectional view of a drinking water device in an embodiment of the present application is shown. The drinking water device provided in an embodiment of the present application can be a device capable of outputting hot water, such as a water purifier and a water dispenser. The drinking water device includes a water tank 60, a heating element assembly and a water outlet assembly. The heating element assembly is respectively connected to the water tank 60 and the water outlet assembly, so that the drinking water in the water tank 60 can pass through the heating element assembly and enter the water outlet assembly, and finally be output to the user through the water outlet assembly, thereby satisfying the user's drinking water needs.

[0049] The heating element assembly includes a heating element body 50 and a cover body 10. A heating channel 58 and a water inlet 61 and a water outlet 62 are formed in the heating element body 50. The water inlet 61 of the heating element body 50 is connected to the water tank 60, so that the drinking water in the water tank 60 can enter the heating channel 58 through the water inlet 61. The drinking water in the heating channel 58 can be heated by the heating element body 50, so that the drinking water is heated to the temperature required by the user.

[0050] Furthermore, the cover member 10 is disposed on the water outlet 62 of the heating body 50, so as to seal the end surface of the heating body 50 having the water outlet 62 through the cover member 10. The cover member 10 also has a water through hole 12, which is connected to the water outlet 62, and the water through hole 12 can also be connected to the water outlet assembly, and the drinking water in the heating flow channel 58 can flow into the water inlet and outlet assembly through the water outlet 62 and the water through hole 12, and finally the heated drinking water is input to the user through the water outlet assembly, thereby satisfying the user's demand for drinking hot water.

[0051] In actual use, the water outlet 12 can be directly connected to the water outlet assembly, or indirectly connected to the water outlet assembly through a water pipe or other connector. Regardless of whether the water outlet 12 is directly or indirectly connected to the water outlet assembly, when the silicone seal 52 on the heating element assembly fails due to aging due to long-term use or encountering other non-standard use conditions such as high temperature, high humidity, abnormal water quality, external impact, skewed assembly, etc., the water outlet 12 may leak at the connection with other components, and the water leaking from the water outlet 12 may drip onto electrical components such as the power cord terminal connector, thereby affecting the normal use of the drinking water equipment and may also cause safety hazards such as short circuit and leakage.

[0052] For this purpose, see Figure 3 and Figure 4The cover member 10 includes a main structure 11 and a pipe structure 20. The main structure 11 is disposed on the end surface of the heating body 50 provided with the water outlet 62, and the end surface of the heating body 50 is sealed by the main structure 11. Further, the cover member 10 also includes a pipe structure 20, which is protruding from the main structure 11 along the vertical direction X, and the pipe structure 20 has a water opening 12 at one end away from the main structure 11. When the main structure 11 is sealed on the end surface of the heating body 50, the water opening 12 is connected to the water outlet 62.

[0053] The cover member 10 further has a water guide port 21 and a drain port 22 connected to the water guide port 21, the water guide port 21 is located below the water through port 12, the plane where the water guide port 21 is located intersects with the vertical direction X, and at least part of the side wall 25 of the pipe structure 20 extends from the water through port 12 to the water guide port 21. In actual use, if the water through port 12 leaks, the water leaked from the water through port 12 will flow along the side wall 25 of the pipe structure 20, and under the guidance of the side wall 25 of the pipe structure 20, the leaked water will flow into the water guide port 21, and finally be discharged through the drain port 22.

[0054] Specifically, if the water outlet 12 leaks, the water leaking from the water outlet 12 will flow downward along the side wall 25 of the pipe structure 20 under the action of gravity. Since the plane where the water outlet 21 is located is not parallel to the vertical direction X, and the water outlet 21 is located below the water outlet 12, when the water moves from the water outlet 12 to the side wall 25 of the water outlet 21, the leaked water will flow into the water outlet 21 under the guidance of the side wall 25, and finally be discharged through the drain 22. In this way, the water leaking from the water outlet 12 can be guided by the above-mentioned cover body 10, so that the leaked water can be discharged to the designated position through the drain 22, avoiding the leaked water from making irregular movements along the surface of the cover body 10, causing the leaked water to drip onto the electrical components inside the drinking water equipment, ensuring the normal use of the drinking water equipment, and reducing safety hazards such as short circuit and leakage.

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

[0056] At least part of the side wall 25 of the pipe structure 20 extends from the water opening 12 to the water guide port 21, which means that all the side walls 25 of the pipe structure 20 can extend to the water guide port 21, or only part of the side walls 25 can extend to the water guide port 21. When all the side walls 25 of the pipe structure 20 extend to the water guide port 21, the water guide port 21 is arranged around the circumference of the pipe structure 20, so that most of the water leaking from the water opening 12 can enter the water guide port 21 along the side walls 25 of the pipe structure 20.

[0057] The circumferential arrangement of the water guide port 21 around the pipeline structure 20 will increase the volume of the cover 10, which is not conducive to reducing the volume of the drinking water device. For this reason, in some embodiments of the present application, the water guide port 21 is located on one side of the pipeline structure 20 in the first direction Y, and the first direction Y intersects with the vertical direction X. That is, only one side wall 25 of the pipeline structure 20 extends the water guide port 21, and the other side wall 25 is not located at the water guide port 21.

[0058] In this way, it is only necessary to set the electrical components that need to be protected in the drinking water equipment on the side of the cover body 10 with the water inlet 21. The water leaking from the water outlet 12 will move along the side wall 25 of the pipe structure 20 to 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 port 22 to avoid 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 body 10 away from the water inlet 21. Since the electrical components that need to be protected in the drinking water equipment are all located on the side of the cover body 10 facing the water inlet 21, even if water on the side wall 25 away from the water inlet 21 drips from the cover body 10, it will not fall on the electrical components and will not cause damage to the electrical components.

[0060] Specifically in one embodiment, the heating element assembly further includes a wire structure 51, which is connected to the heating element body 50 to achieve electrical connection between the heating element body 50 and other electrical devices such as the power supply of the drinking water equipment. Specifically, the wire structure 51 includes a wire body 56 and a wiring terminal 57, the wire body 56 is connected to the heating element body 50 through the wiring terminal 57, the wire body 56 is used to achieve the transmission of current or electrical signals, and the wiring terminal 57 is used to achieve the 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 guide port 21, and the wire structure 51 is hidden below the drain port 22. In this way, part of the water leaking from the water port 12 will be discharged from the drain port 22 through the water guide port 21. Since the wire structure 51 is hidden from the drain port 22, the water entering the water guide port 21 will not drip onto the wire structure 51. The remaining water that does not enter the water guide port 21 will drip from the side of the cover body 10 away from the water guide port 21. Since the wire structure 51 is located on the side of the heating element body 50 facing the water guide port 21, the remaining water will not drip onto the wire structure 51, thereby ensuring the normal operation of the wire structure 51.

[0062] In some embodiments of the present application, refer to Figure 5 and Figure 6 The cover body 10 also includes a retaining structure 30 arranged on the main structure 11. The retaining structure 30 is convexly arranged on the main structure 11 along the vertical direction X. The retaining structure 30 is an annular structure that is not connected at the beginning and the end. It should be noted that the annular structure is not limited to a circle, and can be a square, hexagonal or other irregular shapes.

[0063] Among them, the head end and the tail end of the enclosure structure 30 are arranged at intervals along the second direction Z direction, and the head end and the tail end of the enclosure structure 30 are both connected to the side wall 25 of the pipeline structure 20, so that the enclosure structure 30 and the pipeline structure 20 are jointly enclosed to form a water outlet 21.

[0064] In this way, the pipeline structure 20 is surrounded by the enclosure structure 30 on one side of the first direction Y, and because the head end and the tail end of the enclosure structure 30 are arranged at intervals along the second direction Z, at least part of the side wall 25 of the pipeline structure 20 is located inside the enclosure structure 30, so that after the pipeline structure 20 and the enclosure structure 30 form the water outlet 21, part of the inner wall of the pipeline structure 20 can extend to the water outlet 21.

[0065] Furthermore, after water leaking from the water outlet 12 enters the water guide port 21 under the guidance of the side wall 25, it will be blocked by the enclosure structure 30 within the annular structure formed by the enclosure structure 30, preventing water from dripping from the cover body 10 and only being able to flow out from the drain port 22, thereby achieving the effect of discharging the leaked water from a designated location.

[0066] Specifically in some embodiments, the enclosure structure 30 includes an enclosure wall 31 and a connecting wall 32, both of which protrude from the main structure 11 along the vertical direction X. The enclosure wall 31 includes two enclosure walls 31, and the two enclosure walls 31 are arranged at intervals on the main structure 11 along the second direction Z, and each enclosure wall 31 is connected to the pipeline structure 20 at one end in the first direction Y, and each enclosure wall 31 is connected to the connecting wall 32 at the other end in the first direction Y.

[0067] In this way, the enclosing wall 31 and the connecting wall 32 form an annular structure that is not connected at the head and tail, and the annular structure is a square-like structure, so that the enclosing wall 31 and the connecting wall 32 block the water flowing into the water outlet 21, thereby preventing water from leaking from the side of the cover body 10 having the water outlet 21.

[0068] Specifically in some embodiments, the main structure 11 has a plurality of stepped surfaces 13 arranged in a step-like manner along the first direction Y, all of which are located between two enclosure walls 31, and the height of the stepped surfaces 13 gradually decreases in the direction away from the pipeline structure 20, and a drain port 22 is provided on the stepped surface 13 at the lowest point. In this way, the water entering the water guide port 21 is gradually guided by the plurality of stepped surfaces 13, so that the water flow is finally discharged from the drain port 22. By setting the main structure 11 in a stepped shape, the overall volume of the cover member 10 can be reduced, so that the installation of the components in the drinking water device is more compact, thereby further reducing the volume of the drinking water device.

[0069] Specifically, the main structure 11 includes a first step surface 131 and a second step surface 132, the first step surface 131 is located above the second step surface 132, the connecting wall 32 protrudes from the second step surface 132, and the height of the connecting wall 32 protruding from the first step surface 131 is the same as the height of the panel wall and the protruding first step 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, but only needs to be higher than the second step surface 132 by a certain height, thereby reducing the space occupied by the connecting wall 32 and reducing the volume occupied by the cover member 10 as a whole.

[0070] Specifically in one 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, so that the position of the enclosure wall 31 is limited by the limiting structure 55. When the heating element body is installed along the vertical direction X, by limiting the position of the enclosure wall 31, the installation of the heating element body can be prevented from being tilted in the first direction Y. It is understandable 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, so as to prevent the installation of the heating element body from being tilted in the second direction Z.

[0071] In some embodiments of the present application, the heating body assembly also includes a seal 52, which is sleeved on the pipe structure 20, so that when the pipe structure 20 is inserted into the connecting holes of other components of the drinking water equipment, the seal 52 can seal the gap between the pipe structure 20 and the inner wall of the connecting hole, thereby ensuring that the drinking water in the water outlet 12 can be normally input into the connecting hole.

[0072] In order 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 around the circumference of the pipe structure 20. When the seal 52 is sleeved in the connection hole, the seal 52 is partially located in the installation groove 23, so that the installation of the seal 52 is limited by the installation groove 23 to prevent the seal 52 from being pushed out after installation. When assembling the seal 52, the seal 52 can be pre-installed on the pipe structure 20 before assembly. During disassembly, the sealing groove can ensure that the seal 52 can be removed together with the disassembly of the cover body 10, thereby improving the disassembly efficiency.

[0073] In some embodiments of the present application, a temperature measuring hole 24 is provided on the pipe structure 20, and the temperature measuring hole 24 is connected to the water outlet 12. The heating element assembly further includes a temperature sensing element 53, and the temperature sensing element 53 is provided in the temperature measuring hole 24, so that the drinking water flowing out of the heating element body will not only pass through the water outlet 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 sensing component 53 is fixed to the pipe structure 20 by two screws, and the temperature sensing component 53 is used to monitor the water temperature at the water outlet 62 of the heating element body 50 in real time, so that the system can make real-time corrections to the power of the whole machine to prevent the power of the heating element body 50 from being too high, causing the water to boil in the pipe and abnormal noise of the whole machine. In addition, the water temperature measured by the temperature sensing component 53 is the water temperature of the water that has been completely heated by the heating element body 50, which has a more accurate reference for the correction of the heating power of the whole machine. At the same time, arranging the temperature sensing component 53 on the cover body 10 can avoid opening holes in the stainless steel pipe of the heating element body 50, which is beneficial to reducing the production cost of the heating element. In addition, the heating element body is a high-voltage circuit, and the temperature sensing component 53 is a 5V low-voltage component, which can avoid the influence of high voltage on low voltage.

[0075] Furthermore, the temperature measuring hole 24 is located in the water guide port 21. Thus, when water leakage occurs at the temperature measuring hole 24, the leaked water will also flow out from the drain port 22 and will not flow irregularly along the outer wall of the cover body 10, thereby avoiding affecting the normal operation of electrical equipment such as the conductor structure 51.

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

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

[0078] If there is a water leak at the water port 12, the water leaking from the water port 12 will flow downward along the side wall 25 of the pipe structure 20 under the action of gravity. Since the plane where the water guide port 21 is located is not parallel to the vertical direction X, and the water guide port 21 is located below the water port 12, when the water moves from the water port 12 to the side wall 25 of the water guide port 21, the leaked water will flow into the water guide port 21 under the guidance of the side wall 25, and finally be discharged through the drain port 22. In this way, the water leaking from the water port 12 can be guided by the above-mentioned cover body 10, so that the leaked water can be discharged to the designated position through the drain port 22, avoiding the leaked water from making irregular movements along the surface of the cover body 10, causing the leaked water to drip onto the electrical components inside the drinking water equipment, ensuring the normal use of the drinking water equipment, and reducing safety hazards such as short circuit and leakage.
