Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water purifiers, in particular to a water purifier heating assembly. BACKGROUND

[0002] As a device capable of filtering and purifying tap water, the water purifier is increasingly recognized and favored by consumers, and gradually becomes an indispensable product in life. At present, most water purifiers are equipped with heating function, which can provide users with normal temperature purified water and heated purified water. The water purifier equipped with heating function is provided with a filter element and a heating body. The working principle is that the purified water produced by the filter element after filtering the tap water is directly output or output after being heated by the heating body, so as to realize the functions of outputting normal temperature water or hot water after being connected to the water outlet nozzle or faucet.

[0003] The heating body in some water purifiers is usually in the form of a tank body structure. In order to achieve light and thin design, the heating body is generally vertically arranged in the machine body shell. The water inlet pipe of the heating body is located at the bottom and connected with the upstream water supply structure. The water outlet pipe of the heating body is located at the top and connected with the downstream water outlet structure. Under the action of various factors such as machining error, assembly error and the difficulty of keeping the water pressure in the waterway constant, the connection point between the water outlet pipe of the heating body and the downstream water outlet structure is often a part with a relatively high risk of water leakage. Although some water purifiers are provided with sealing rings between the water outlet pipe and the downstream water outlet structure, which can improve the above problems to a certain extent, the sealing property may be lost due to the failure of the sealing ring, thereby causing water leakage. Some water purifiers connect the water outlet pipe and the downstream waterway structure through a silica gel hose. However, the silica gel hose is easy to deform and loose from the water outlet pipe, thereby causing water leakage. Once water leakage occurs, water flows downward to the heating body, which is easy to cause the water leakage of the wiring terminal of the heating body and even damage the heating body. In addition, the silica gel hose is easy to absorb odor, resulting in odor in the drinking water. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a water purifier heating assembly to solve the technical problem that the connection point between the water outlet pipe of the heating body and the downstream waterway structure in the existing water purifier heating assembly is easy to cause the water leakage of the wiring terminal of the heating body and even damage the heating body.

[0005] The technical scheme adopted by the present application is as follows:

[0006] A water purifier heating assembly, comprising a heating body, wherein the top of the heating body is provided with a water outlet pipe, and the heating body is provided with a wiring terminal. The water purifier heating assembly further comprises a water blocking member, wherein the water blocking member is provided with a water blocking surface, the water blocking surface is provided with a drainage hole and a sleeve hole matched with the water outlet pipe, the water blocking member is sleeved on the water outlet pipe through the sleeve hole, and the projection of the drainage hole on the horizontal plane falls outside the projection of the heating body on the horizontal plane.

[0008] The water blocking component is provided with a water blocking rib surrounding the water blocking surface, and the water blocking rib and the water blocking surface surround a water blocking groove with an upward opening.

[0009] In the technical solution, the water blocking rib and the water blocking surface surround a water blocking groove with an upward opening, on one hand, the water blocking groove is used to collect the water leaked from the connection point of the water outlet pipe and the downstream waterway structure, the water droplets splashed outward when the water flow collides with the water blocking surface are blocked by the water blocking rib to prevent the water droplets from splashing toward the heating body, on the other hand, the space in the water blocking groove can accommodate more water, and the water flow is completely guided to the drain hole to avoid the overflow of the water flow from the water blocking surface due to too much water leakage in a short time.

[0010] The water blocking surface is provided with a flow guiding boss protruding upward, the sleeve hole is arranged on the flow guiding boss, and the flow guiding boss is used to guide the liquid to the drain hole.

[0011] In the technical solution, the flow guiding boss is used to guide the water leaked from the upper end of the water outlet pipe to flow toward the drain hole in an orderly manner, and then quickly flow out through the drain hole to avoid the overflow of the water in the water blocking groove due to too high water level.

[0012] The flow guiding boss is provided with a flow guiding surface, the flow guiding surface is arranged in an arc shape gradually rising from the outer periphery to the center, and the sleeve hole is arranged at the center of the flow guiding surface.

[0014] The water blocking surface is provided with an inclined surface surrounding the flow guiding boss, and the drain hole is arranged at a low position of the inclined surface.

[0015] In the technical solution, the inclined surface has a guiding effect on the water flow, so that the water flow flows from the high position of the inclined surface to the low position, the water flow in the water blocking surface can be fully discharged through the drain hole, and the residual water is avoided.

[0016] The bottom of the water blocking piece is provided with a downwardly extending supporting rib, the supporting rib is arranged around the sleeve hole, and the water blocking piece is abutted against the heating body through the supporting rib.

[0018] An NTC temperature sensor is mounted on the top of the heating body, and the NTC temperature sensor is located in the space surrounded by the supporting rib.

[0019] In the technical solution, the NTC temperature sensor is arranged in the space surrounded by the supporting rib, so that the NTC temperature sensor is protected by the supporting rib, thereby avoiding water splashing on the NTC temperature sensor when the drain hole drains water downward.

[0020] The water blocking piece is arranged in a flexible structure, the inner diameter of the sleeve hole is smaller than the outer diameter of the water outlet pipe, and the sleeve hole is arranged in an interference fit on the water outlet pipe.

[0021] In the technical solution, the water blocking piece is arranged in an interference fit on the water outlet pipe, which improves the mounting firmness of the water blocking piece on the heating body and also makes the inner wall of the sleeve hole tightly fit the water outlet pipe, thereby improving the sealing performance and avoiding water flowing downward between the inner wall of the sleeve hole and the water outlet pipe when the connection point between the water outlet pipe and the downstream waterway structure leaks.

[0022] The water purifier heating assembly further comprises a quick connector and a PE pipe, and the water outlet pipe and the PE pipe are connected through the quick connector.

[0023] In the technical solution, the PE pipe can be used as a pipeline for connecting the water purifier heating assembly and the downstream waterway structure. The PE pipe is connected to the water outlet pipe through the quick connector, which is convenient and fast to install. The PE pipe is made of polyethylene plastic, which has the characteristics of high temperature resistance and high strength. By using the PE pipe to replace the silica gel hose to connect the water outlet pipe and the downstream waterway structure, the waterway is designed without silica gel contact, thereby avoiding the problem that silica gel adsorbs odors and causes drinking water to have an odor.

[0024] The water outlet pipe is arranged as a metal pipe, the heating body comprises a metal upper end cover, and the water outlet pipe is welded to the metal upper end cover.

[0025] In the technical solution, the water outlet pipe and the metal upper end cover are welded as a whole, which avoids the problem of a gap between the water outlet pipe and the metal upper end cover, ensures the sealing performance of the heating body, saves the sealing ring arranged between the water outlet pipe and the metal upper end cover, and simplifies the assembly process and sealing cost of the heating assembly.

The connection point of the water outlet pipe and the downstream waterway structure is located above the water blocking surface. When the connection point leaks, the water flows downward to the water blocking surface and flows toward the drain hole, and finally flows out through the drain hole. Since the drain hole and the wiring terminal are located on opposite sides of the water purifier heating assembly, and the projection of the drain hole on the horizontal plane falls outside the projection of the heating body on the horizontal plane, the water flowing from the drain hole is far away from the wiring terminal of the heating body and cannot flow to the heating body, so that the leaked water flow does not cause the wiring terminal to be wet and short-circuit and damage, and the use safety of the water purifier is improved.

Of course, those skilled in the art can understand that the above structure is only a specific example and illustrative description, and cannot constitute a specific limitation on the technical solutions provided by the present application.

[0045] Referring to Figures 1 to 6 As shown in the drawings, the water purifier heating assembly provided by the present application comprises a heating body 1, the top of the heating body 1 is provided with a water outlet pipe 11, the heating body 1 is provided with a wiring terminal 12, the water purifier heating assembly further comprises a water blocking piece 2, the water blocking piece 2 is provided with a water blocking surface 21, the water blocking surface 21 is provided with a drain hole 22 and a sleeve hole 23 matched with the water outlet pipe 11, the water blocking piece 2 is sleeved on the water outlet pipe 11 through the sleeve hole 23, and the projection of the drain hole 22 on the horizontal plane falls outside the projection of the heating body 1 on the horizontal plane.

[0046] The water purifier heating assembly provided by the present application is provided with a water blocking piece 2, the water blocking surface 21 of the water blocking piece 2 is provided with a drain hole 22 and a sleeve hole 23 matched with the water outlet pipe 11, the water blocking piece 2 is sleeved on the water outlet pipe 11 through the sleeve hole 23, so that the water blocking surface 21 surrounds the water outlet pipe 11 to form a water blocking effect. The connection point of the water outlet pipe 11 and the downstream waterway structure is located above the water blocking surface 21, when the connection point leaks, the water flows downward to the water blocking surface 21 and flows towards the drain hole 22, and finally flows out through the drain hole 22; since the projection of the drain hole 22 on the horizontal plane falls outside the projection of the heating body 1 on the horizontal plane, the water flowing from the drain hole 22 flows away from the wiring terminal 12 of the heating body 1 and does not flow onto the heating body 1, so as to avoid that the leaked water flow causes the wiring terminal 12 to be wet and short-circuit and damaged, and improve the use safety of the water purifier.

[0047] In a preferred embodiment, the drain hole 22 and the terminal 12 can be arranged on opposite sides of the water purifier heating assembly, so as to increase the distance between the drain hole 22 and the terminal 12 as much as possible. In another preferred embodiment, for the water purifier, a water receiving structure can be arranged below the drain hole 22, or a water receiving pipe is connected to the drain hole 22, and the water receiving pipe is connected to the municipal sewer, so that the water flowing out of the drain hole 22 is discharged to a designated position through the water receiving pipe.

[0048] As a preferred embodiment of the present application, as shown in Figure 3 and Figure 5 , the water blocking part 2 is provided with a water blocking rib 24 surrounding the water blocking surface 21, and the water blocking rib 24 and the water blocking surface 21 form a water blocking groove 25 with an upward opening. In the technical solution, by forming the water blocking groove 25 with the water blocking rib 24 and the water blocking surface 21, on the one hand, the water blocking groove 25 is used to collect the water leaking from the connection point of the water outlet pipe 11 and the downstream waterway structure, and the water blocking rib 24 is used to block the water droplets splashing outward when the water flow collides with the water blocking surface 21, preventing the water droplets from splashing toward the heating body 1, on the other hand, the space in the water blocking groove 25 can accommodate more water, and the water flow is completely guided to the drain hole 22, so as to avoid the overflow of the water flow from the water blocking surface 21 caused by too much water leaking in a short time. In specific implementation, under the premise that the water blocking rib 24 does not interfere with other parts in the water purifier, the height of the water blocking rib 24 can be increased as much as possible, so as to increase the accommodation space of the water blocking groove 25, and further improve the water blocking effect.

[0049] As a preferred embodiment of the present application, as shown in Figure 3 and Figure 5 , the water blocking surface 21 is provided with a flow guiding boss 26 protruding upward, the sleeve hole 23 is arranged in the flow guiding boss 26, and the drain hole 22 is arranged outside the flow guiding boss 26, and the flow guiding boss 26 is used to guide the liquid to the drain hole 22. In the technical solution, by arranging the flow guiding boss 26, the flow guiding boss 26 can guide the water leaking from the upper end of the water outlet pipe 11 to flow orderly toward the drain hole 22 and be discharged. Moreover, when the present solution is used in combination with the aforementioned embodiment in which the water blocking part 2 is provided with the water blocking rib 24, the flow guiding boss 26 guides the water flow to flow toward the water blocking groove 25, so as to accelerate the discharge of the water flow to the drain hole 22, and avoid the overflow of the water in the water blocking groove 25 due to the high water level. In addition, since the sleeve hole 23 is arranged in the flow guiding boss 26, the length of the sleeve hole 23 is increased by the protruding effect of the flow guiding boss 26, which helps to improve the reliability of the water blocking part 2 holding the water outlet pipe 11.

[0050] As a preferred embodiment, as shown in Figure 3 and Figure 5As shown, the flow guide boss 26 is provided with a flow guide surface 261, which is an arc surface gradually rising from the outer periphery to the center. Those skilled in the art can understand that when the connection point of the water outlet pipe 11 and the downstream waterway structure leaks, the water flow will probably flow downward along the wall of the water outlet pipe 11, and thus the water flow will first contact the center of the flow guide surface 261. Since the flow guide surface 261 gradually decreases from the center to the outer periphery, the flow guide effect of the flow guide surface 261 causes the water flow to quickly flow downward along the arc surface to the position of the drain hole 22 and be discharged.

[0051] As a preferred embodiment, the water retaining surface 21 is provided with an inclined surface surrounding the flow guide boss 26, and the drain hole 22 is arranged at a low position of the inclined surface. Figure 3 In the embodiment shown in the figure, the inclined surface here refers to the surface between the water retaining rib 24 and the flow guide boss 26, Figure 3 In the figure, the position where the inclined surface is connected with the flow guide boss 26 is a high position, and the position where the inclined surface is connected with the water retaining rib 24 is a low position. This surface is also the bottom of the water retaining groove 25. The leaked water is mainly concentrated here. Therefore, by arranging the surface as an inclined surface and arranging the drain hole 22 at a low position of the inclined surface, the guiding effect of the inclined surface on the water flow contained in the water retaining groove 25 can be utilized to make the water flow flow from the high position of the inclined surface to the low position. The water flow in the water retaining groove 25 can be fully discharged through the drain hole 22, avoiding water remaining. In addition, the discharging speed of the water flow can be accelerated, and the water level in the water retaining groove 25 can be prevented from being too high to overflow.

[0052] As a preferred embodiment of the present application, as shown in Figure 3 and Figure 6 The bottom of the water retaining member 2 is provided with a support rib 27 extending downward, the support rib 27 is arranged around the sleeve hole 23, and the water retaining member 2 is abutted with the heating body 1 through the support rib 27. In this technical solution, on the one hand, the support rib 27 helps to strengthen the structural strength of the water retaining member 2, and on the other hand, the abutment of the heating body 1 and the support rib 27 can support the water retaining member 2, effectively preventing the water retaining member 2 from being deformed to affect the water retaining effect. Since the support rib 27 lifts the water retaining surface 21 upward by a certain height, in a preferred embodiment, the bottom of the water retaining member 2 can be provided with a mounting protrusion 28, the sleeve hole 23 penetrates the mounting protrusion 28, and the bottom surface of the mounting protrusion 28 is abutted with the heating body 1, thereby further improving the reliability of the cooperation between the water retaining member 2 and the water outlet pipe 11 and reducing the risk of deformation of the water retaining member 2.

[0053] In a preferred embodiment, as shown in Figure 2 and Figure 4As shown, the top of the heating body 1 is provided with an NTC temperature sensor 13, which is located in the space surrounded by the support rib 27. The NTC temperature sensor 13 at the top of the heating body 1 is used for detecting the outlet water temperature of the heating body 1, and is close to the connection point between the outlet pipe 11 and the downstream waterway structure, and is also close to the drain hole 22. Therefore, by arranging the NTC temperature sensor 13 in the space surrounded by the support rib 27, the support rib 27 can protect the NTC temperature sensor 13 from being splashed by water flowing downward from the drain hole 22.

[0054] In a preferred embodiment, as shown in Figure 1 and Figure 6 As shown, the support rib 27 is provided with an inspection window 271, and the lower end of the sleeve hole 23 is exposed to the outside view through the inspection window 271. Those skilled in the art can understand that when water leakage detection or maintenance is performed, the contact position of the lower end of the sleeve hole 23 with the heating body 1 and the position where the outlet pipe 11 penetrates out of the heating body 1 also need to be observed for water leakage. However, the support rib 27 surrounds the sleeve hole 23, which will block the view. Therefore, by providing the inspection window 271, when maintenance is performed, the operator can perform maintenance through the inspection window 271 without disassembling the water blocking member 2, thereby improving the convenience of maintenance.

[0055] As a preferred embodiment of the present application, the water blocking member 2 is provided in a flexible structure, and the inner diameter of the sleeve hole 23 is smaller than the outer diameter of the outlet pipe 11, so that the sleeve hole 23 is provided in an interference fit on the outlet pipe 11. In this technical solution, by providing the water blocking member 2 in an interference fit on the outlet pipe 11, the installation firmness of the water blocking member 2 on the heating body 1 is improved, and the inner wall of the sleeve hole 23 is tightly matched with the outlet pipe 11, thereby improving the sealing performance and avoiding water flowing downward between the inner wall of the sleeve hole 23 and the outlet pipe 11 when water leakage occurs. In a preferred embodiment, the water blocking member 2 can be made of flexible silicone rubber material. The silicone rubber material has good high-temperature resistance and can cope with the high-temperature state when hot water flows out of the outlet pipe 11. In addition, the silicone rubber material also has good flexibility and resilience, so that the water blocking member 2 can tightly hold the outlet pipe 11, thereby avoiding the generation of a water leakage gap between the inner wall of the sleeve hole 23 and the outlet pipe 11.

[0056] As a preferred embodiment of the present application, as shown in Figures 1 to 3As shown, the water purifier heating assembly further comprises a quick connector 3 and a PE pipe 4, and the water outlet pipe 11 and the PE pipe 4 are connected through the quick connector 3. The PE pipe 4 can be used as a pipeline for connecting the water purifier heating assembly and the downstream waterway structure. The PE pipe 4 is connected with the water outlet pipe 11 through the quick connector 3, which is convenient and fast to install. The PE pipe 4 is made of polyethylene plastic, which has the characteristics of high temperature resistance and high strength. By using the PE pipe 4 to replace the silica gel hose to connect the water outlet pipe 11 and the downstream waterway structure, the waterway design without silica gel contact is realized, and the problem of peculiar smell caused by silica gel adsorption in drinking water is avoided. Further preferably, the quick connector 3 can be a metal high-temperature-resistant quick connector 3.

[0057] Further, the water outlet pipe 11 is provided as a metal pipe, the heating body 1 comprises a metal upper end cover, and the water outlet pipe 11 is welded with the metal upper end cover. Compared with the existing mode that the end cover of the heating body 1 is inserted with the water outlet pipe 11, the water outlet pipe 11 is welded with the metal upper end cover as a whole in the present application, which avoids the problem of insertion gap between the water outlet pipe 11 and the metal upper end cover, ensures the sealing performance of the heating body 1, saves the sealing ring arranged between the two, simplifies the assembly process and sealing cost of the heating assembly. In addition, the water outlet pipe 11 is a metal pipe, which can specifically adopt a stainless steel pipe, a copper pipe or other suitable structure, and can more stably and reliably support the water blocking piece 2 compared with a plastic pipe.

[0058] The places not described in the present application can be realized by using or referring to the existing technology.

[0059] Each embodiment in the present specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other, and each embodiment mainly describes the difference from other embodiments.

[0060] The above only describes the embodiments of the present application and is not used to limit the present application. The present application can have various changes and modifications for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the scope of claims of the present application.
