These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application for technical users in the field by referring to specific embodiments. DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be described clearly and completely in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technical users in this field without creative work are within the scope of protection of this application.

[0037] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0038] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0039] In the prior art, the water heater is mounted on a mounting wall, and pipe fittings are mounted on the water heater, through which the water heater can be connected to a water pipe at the installation site.

[0040] One end of the pipe is connected to the water heater, and the other end extends into the installation wall and is connected to the water pipe. Therefore, part of the pipe is exposed between the installation wall and the water heater. In order to prevent this part of the pipe from being accidentally touched and improve the overall protection effect of the water heater, a retaining shell is also provided on the water heater. The retaining shell is located on the side of the pipe facing the user and shields this side.

[0041] However, in order to control production and processing costs and facilitate installation and transportation, the baffle shells are usually designed to have the same specifications and sizes. However, due to the differences in the installation locations of the water heaters, the distance between the water heaters and the installation wall after installation is different.

[0042] Therefore, the baffle shell is difficult to adapt to the different intervals between the water heater and the installation wall. Even if the baffle shell is installed, there is still a gap between the baffle shell and the installation wall. Some pipes will still be exposed from the baffle shell in the gap between the baffle shell and the installation wall, and the specific exposed lengths vary. There is a lack of effective shielding protection, resulting in poor shielding effect of the baffle shell on the pipes.

[0043] To solve the above problems, the present application provides a shielding cover and a water heater. By providing a shielding cover with a telescopic part, the length of the shielding cover can be adjusted under the telescopic action of the telescopic part, and it can be flexibly adapted to different intervals between the water heater and the installation wall, thereby improving the shielding effect on the pipes.

[0044] Figure 1 A schematic diagram of the structure of the shielding cover provided in an embodiment of the present application; Figure 2 for Figure 1 A schematic diagram of the structure of the shielding cover when viewed from above; Figure 3 A diagram showing the use status of the shielding cover provided in an embodiment of the present application; Figure 4 for Figure 3 Schematic diagram from top view.

[0045] On the one hand, referring to Figures 1 to 4As shown, the present application provides an embodiment of a shielding cover 200, which is used to shield the pipe 130 of the water heater 100, including a first connecting member 210, a telescopic member 220 and a second connecting member 230 connected in sequence, one of the first connecting member 210 and the second connecting member 230 is used to connect to the water heater 100, and the other is used to connect to the installation wall 300 where the water heater 100 is located, and the telescopic member 220 is used to cover the pipe 130;

[0046] The telescopic member 220 is configured to extend or shorten as the first connecting member 210 and the second connecting member 230 move away from or approach each other.

[0047] The first connector 210, the telescopic member 220 and the second connector 230 are connected in sequence, and a through passage is formed therebetween for the pipe 130 to pass smoothly. The first connector 210 and the second connector 230 serve as ports of the passage, one of which is connected to the water heater 100 and the other is connected to the installation wall 300, so that the telescopic member 220 can cover the pipe 130 and achieve a sight shielding and protective effect on the pipe 130 to prevent users from accidentally touching the pipe 130.

[0048] It is understood that since the pipe 130 is generally Figure 3 It is arranged below the housing 110 of the water heater 100 and extends into the installation wall 300 along the horizontal front-to-back direction. Therefore, the housing 110 of the water heater 100 can shield the top of the pipe 130, and the telescopic member 220 needs to shield at least the left side, right side and bottom side of the pipe 130.

[0049] Thus, the telescopic member 220 can be set as a sleeve-like structure with the upper side, lower side, left side and right side all closed to form a circumferential shielding of the pipe 130, or the telescopic member 220 can be set as a cover-like structure with only the lower side, left side and right side shielding and the upper side open, so that the shielding cover 200 and the lower side of the housing 110 jointly form a circumferential shielding of the pipe 130. This application is not limited to this.

[0050] When the first connecting member 210 and the second connecting member 230 are connected to the water heater 100 and the installation wall 300 respectively, the distance between the first connecting member 210 and the second connecting member 230 will be different due to the different distances between the water heater 100 and the installation wall 300, so that the distance between the first connecting member 210 and the second connecting member 230 will be different. At this time, the telescopic characteristics of the telescopic member 220 can be used to make the telescopic member 220 extend or shorten as the first connecting member 210 and the second connecting member 230 move away from or close to each other, so as to adjust the distance between the shielding cover 200 and the installation wall 300. Figure 1 and Figure 3 The overall length in the front-to-back direction is adapted to the length of the exposed pipe 130, thereby ensuring the shielding effect of the pipe 130.

[0051] Therefore, the shielding cover 200 provided in the present application is provided with a first connecting member 210 , a telescopic member 220 and a second connecting member 230 , so that the telescopic member 220 is extended or shortened as the first connecting member 210 and the second connecting member 230 move away from or close to each other.

[0052] Therefore, when the exposed length of the pipe fitting 130 between the water heater 100 and the installation wall 300 is different and there is a lack of shielding, the shielding cover 200 can be set on the pipe fitting 130, and the distance between the first connecting member 210 and the second connecting member 230 can be flexibly adjusted through the telescopic member 220 to adapt to the exposed length of the pipe fitting 130, and the first connecting member 210 and the second connecting member 230 are respectively connected to the water heater 100 and the installation wall 300 to achieve full shielding of the pipe fitting 130 and avoid exposure of the pipe fitting 130, thereby improving the shielding effect of the pipe fitting 130.

[0053] Furthermore, based on the telescopic characteristics of the telescopic member 220, the shielding cover 200 can be at least partially extended only when in use to match the exposed length of the tube 130, and during transportation and storage after production, it can be kept in a shortened state, making its overall volume smaller, saving space, and facilitating transportation and storage.

[0054] In addition, when the shielding cover 200 has been installed on the water heater 100 and maintenance and inspection operations are required on the pipe 130, the shielding cover 200 can be shortened directly without being completely removed. After the maintenance and inspection is completed, it can be extended and fixed, which is convenient, fast and easy to operate.

[0055] In some embodiments, reference Figure 1 and Figure 2 As shown, the telescopic member 220 includes a plurality of telescopic joints 221, and each telescopic joint 221 is sequentially connected along the first connecting member 210 to the second connecting member 230;

[0056] At least one telescopic section 221 is configured to extend or shorten as the first connecting member 210 and the second connecting member 230 move away from or toward each other, so as to drive the telescopic member 220 to extend or shorten.

[0057] It is understandable that in order to make the telescopic action of the telescopic member 220 more flexible and more convenient to adapt to the exposed pipes 130 of different lengths, a plurality of edges can be provided. Figure 1 and Figure 2 The extension or shortening of the extension joints 221 can be regarded as the extension joints 221 approaching or moving away from each other in the front-to-back direction, or the extension joints 221 themselves folding or unfolding in the front-to-back direction, and can maintain the current position state by themselves without external force, so that the telescopic member 220 can maintain the extension or shortening state.

[0058] Furthermore, when the first connecting member 210 and the second connecting member 230 move away from or closer to each other, at least one of the telescopic joints 221 can move synchronously with one of the first connecting member 210 and the second connecting member 230, or at least one of the telescopic joints 221 can be unfolded or folded accordingly, so as to achieve the overall extension or shortening of the telescopic member 220 through the compensation action of at least one telescopic joint 221.

[0059] The action of any telescopic joint 221 is relatively independent from the action of the adjacent telescopic joint 221 , that is, when the telescopic joint 221 moves, it does not necessarily trigger the action of the adjacent telescopic joint 221 .

[0060] Specifically, the number of telescopic joints 221 may be determined according to the maximum displacement between the two ends of each telescopic joint 221 along the front-to-back direction, or may be determined according to the change in the folding size of the telescopic joint 221 itself along the front-to-back direction, and the present application does not impose any limitation on this.

[0061] Further, in some embodiments, Figure 1 and Figure 2 As shown, the expansion joint 221 is an elastic corrugated ring.

[0062] It can be understood that the elastic corrugated ring is used as the telescopic joint 221, which can be folded or unfolded. The elastic corrugated rings are connected in sequence along the folding direction of their own corrugations to form a bellows structure. Figure 1 and Figure 2 The bellows structure is connected in the front-to-back direction so that the whole structure has elastic wrinkles along the front-to-back direction, which makes the force sensitivity of the bellows structure in the front-to-back direction higher and the structural strength in the up-down-left-to-right direction higher.

[0063] Therefore, by using a bellows structure as the telescopic part 220, the shielding cover 200 can form an accordion-type telescopic structure, reduce the force required when the telescopic part 220 is telescoped in the front-to-back direction, simplify the telescopic operation, and increase the strength of the telescopic part 220 in the up, down, left and right directions, thereby improving the protective effect of the telescopic part 220 on the pipe 130.

[0064] In other embodiments, the telescopic joint 221 may also be Figure 1 and Figure 2 The rings are nested in layers in the front-to-back direction and slidably connected in sequence. The rings can move closer to or farther away from each other to shorten or lengthen the telescopic member 220 as a whole. Similarly, the rings can be extended in the front-to-back direction to form a sleeve, thereby reducing the number of telescopic joints 221 set and simplifying the structure of the telescopic member 220.

[0065] And in some embodiments, such as Figure 3As shown, the side of the telescopic member 220 facing the water heater 100 is configured as a conformal surface 222 adapted to the shape of the housing 110 of the water heater 100 .

[0066] like Figure 3 As shown, the side of the shell 110 of the water heater 100 facing the shielding cover 200 is an arc-shaped surface, and the upper surface of the telescopic member 220 is an arc-shaped structure adapted to the arc-shaped shell 110, thereby forming a conforming surface 222. And because the telescopic member 220 itself can be extended or shortened, when the shielding cover 200 is applied to water heaters 100 of different sizes, while adjusting the length of the telescopic member 220, the curvature of the conforming surface 222 on its upper side also changes with the length of the telescopic member 220, and is always adapted to the shell 110 of the water heater 100 of the corresponding size.

[0067] By setting the side of the telescopic member 220 facing the water heater 100 as a conformal surface 222, the gap between the shielding cover 200 and the water heater 100 can be reduced, and the shielding effect of the shielding cover 200 on the pipe 130 can be improved, making the overall structure of the water heater 100 more compact and beautiful, and providing a better user experience.

[0068] In other embodiments, when the side of the shell 110 of the water heater 100 facing the shielding cover 200 is a horizontal plane or an inclined plane, the conformal surface 222 of the telescopic member 220 can also be arranged to adapt to the side surface of the shell 110. The present application does not impose any specific restrictions on the shape of the conformal surface 222.

[0069] In specific implementation, Figure 3 and Figure 4 As shown, the first connector 210 is used to be plugged into the retaining shell 120 that shields a portion of the pipe 130 on the water heater 100 .

[0070] It is understandable that some water heaters 100 are originally provided with a baffle shell 120 underneath, and the baffle shell 120 partially shields the front, left, right and bottom sides of the pipe fitting 130 from one end of the pipe fitting 130 close to the water heater 100, and part of the pipe fitting 130 is still exposed between the rear side of the baffle shell 120 and the installation wall 300, so that the first connecting piece 210 of the shielding cover 200 can be plugged into the rear side of the baffle shell 120, and the shielding cover 200 can be used to shield this part of the pipe fitting 130.

[0071] Furthermore, the second connecting member 230 includes a supporting portion 231 and a connecting portion 232 . One end of the supporting portion 231 is connected to the telescopic member 220 , and the connecting portion 232 is connected to the other end of the supporting portion 231 . The connecting portion 232 is used to connect to the installation wall 300 .

[0072] It can be understood that the second connecting member 230 is used to connect to the installation wall 300. Specifically, the second connecting member 230 includes a supporting portion 231 and a connecting portion 232 that are connected to each other. The supporting portion 231 is located on the side facing the first connecting member 210 and is connected to the telescopic member 220. The connecting portion 232 is located on the side away from the first connecting member 210 and is connected to the installation wall 300.

[0073] Among them, Figures 1 to 4 As shown, the first connecting member 210 and the supporting portion 231 are both rectangular sleeves, and the connecting portion 232 is a flange disposed at the end of the supporting portion 231 .

[0074] Since a rectangular socket is formed on the rear side of the baffle shell 120, the first connecting member 210 is set as a rectangular sleeve to facilitate the plugging of the first connecting member 210 with the baffle shell 120. Any cross-section of the telescopic member 220 in the plane in the up, down, left and right directions is also rectangular, which is convenient for connection with the first connecting member 210. Furthermore, the support part 231 is also set as a rectangular sleeve, which is convenient for connection with the telescopic member 220 and makes the overall structure of the shielding cover 200 consistent and compact.

[0075] The connection portion 232 is configured as a flange on the outer side of the end of the support portion 231 , which has a simple structure and is convenient for forming a connection plane adapted to the installation wall 300 , thereby improving the reliability of the connection between the shielding cover 200 and the installation wall 300 .

[0076] In other embodiments, if the baffle shell 120 is not provided under the water heater 100, the first connecting member 210 can be extended and bent upward to form a structure similar to the baffle shell 120, and the first connecting member 210 can be directly connected to the water heater 100 to ensure the shielding effect of the pipe 130. The present application does not impose any restrictions on this.

[0077] In addition, the shielding cover 200 provided in the embodiment of the present application also includes at least one fastener (not shown), and the first connecting member 210 and the shielding shell 120, and the connecting part 232 are connected to at least one of the installation walls 300 through fasteners to improve the stability of the installation of the shielding cover 200.

[0078] Specifically, the fasteners may be bolts or screws, so that the first connecting member 210 can be threadedly connected to the baffle housing 120 (or the shell 110 of the water heater 100 ), and the connecting portion 232 of the second connecting member 230 can be threadedly connected to the installation wall 300 .

[0079] The fasteners may also be structures such as adhesives or snaps, and thereby the first connector 210 is bonded or snapped to the baffle 120 (or the water heater 100 housing 110), and the connecting portion 232 of the second connector 230 is bonded or snapped to the mounting wall 300, and the present application does not impose any restrictions on this.

[0080] In addition, when implementing it, refer to Figure 1 and Figure 2 As shown, the first connecting member 210, the telescopic member 220 and the second connecting member 230 are integrally formed.

[0081] In this way, the shielding cover 200 can be an integrally formed part, which has a simple structure and is easy to process, and has higher sealing and shielding properties. Specifically, the shielding cover 200 can be made of plastic or metal, and this application does not limit this.

[0082] Therefore, in some embodiments, the first connecting member 210, the telescopic member 220 and the second connecting member 230 may be processed separately, and the materials of the three members may be adjusted according to the use requirements, and then the three members may be fixedly connected.

[0083] Furthermore, when any one of the first connecting member 210, the telescopic member 220 and the second connecting member 230 in the shielding cover 200 is made of plastic, translucent plastic can also be used to form a physical shielding for the pipe 130 without completely blocking the user's line of sight, making it easier for the user to intuitively observe the external structure of the pipe 130 and improving the user experience.

[0084] On the other hand, the present application provides a water heater 100 , comprising a water heater 100 body and a shielding cover 200 in any of the above embodiments, wherein the shielding cover 200 is connected to the water heater 100 body.

[0085] The shielding cover 200 has been described in detail in the above embodiments and will not be described again herein.

[0086] In summary, the shielding cover 200 and the water heater 100 provided in the present application, the shielding cover 200 is provided with a first connecting member 210, a telescopic member 220 and a second connecting member 230, so that the telescopic member 220 extends or shortens as the first connecting member 210 and the second connecting member 230 move away from or close to each other.

[0087] Therefore, when the exposed length of the pipe fitting 130 between the water heater 100 and the installation wall 300 is different and there is a lack of shielding, the shielding cover 200 can be set on the pipe fitting 130, and the distance between the first connecting member 210 and the second connecting member 230 can be flexibly adjusted through the telescopic member 220 to adapt to the exposed length of the pipe fitting 130, and the first connecting member 210 and the second connecting member 230 are respectively connected to the water heater 100 and the installation wall 300 to achieve full shielding of the pipe fitting 130 and avoid exposure of the pipe fitting 130, thereby improving the shielding effect of the pipe fitting 130.

[0088] So far, the technical solution of the present application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for technical users in the field to understand that the protection scope of the present application is obviously not limited to these specific embodiments. The above embodiments are only used to illustrate the technical solution of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technical users in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solution to deviate from the scope of the technical solutions of the embodiments of the present application.
