Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a gas water heater. Background Technology

[0002] As people's living standards improve, more and more household appliances are being used in their daily lives. Among them, gas water heaters have gained widespread recognition and application due to their fast heating speed, lack of water storage, and instant hot water supply.

[0003] Currently, after gas water heaters are installed, the pipes are often exposed, affecting the overall appearance and shortening the lifespan of the pipes. In some technologies, users use perforated panels to assemble coveres to conceal the exposed pipes. However, the thickness of the water heater casing varies between different models, while the dimensions of the cover along the thickness of the casing are relatively fixed. This results in the cover not fully fitting the casing of some water heaters, hindering both proper pipe concealment and cover installation. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a gas water heater that can effectively solve the problem of mismatch between the size of the shield and the outer shell of the water heater.

[0005] The above-mentioned technical problems are solved by the following technical solutions:

[0006] A gas water heater, comprising:

[0007] Water heater casing;

[0008] A shielding assembly includes a shield and an extension plate. The shield is detachably mounted on the bottom of the water heater casing. The shield includes a main body plate and two side plates connected to the main body plate. The two side plates are located on opposite sides of the width direction of the water heater casing. The extension plate is arranged in a one-to-one correspondence with the side plates and slides along the thickness direction of the water heater casing on the corresponding side plates. A receiving cavity is formed between the shield and the two extension plates, which can accommodate the pipes connected to the gas water heater.

[0009] The gas water heater described in this utility model has the following advantages compared with the prior art:

[0010] For water heater shells of varying thicknesses, an extension plate can be slid along the thickness direction of the shell. This allows the extension plate to protrude from the side panel away from the main body and align with the rear end of the water heater shell (e.g., with the rear edge of the side panel or the back panel). It also aligns the main body with the front end of the shell, enabling the shielding assembly to adapt to water heater shells of different thicknesses. This shielding assembly helps reduce the probability of gaps appearing due to the side panel being too long along the shell's thickness, which could cause misalignment between the main body and the front end of the shell. Furthermore, it improves the coverage of pipes connected to the gas water heater, resulting in a cleaner and more refined appearance.

[0011] In one embodiment, the side panel of the cover is provided with a sliding groove, and the extension plate slides into the sliding groove.

The bottom of the extension plate is slidably engaged with the corresponding second sliding groove.

[0023] In one embodiment, the extension plate is configured as a ferromagnetic plate and is magnetically attracted to the first magnetic attractor.

[0024] In one embodiment, the shield further includes a third support portion, which is disposed on the top of the main body plate and fits against the bottom of the water heater casing;

[0046] Reference Figures 1 to 4 As shown, this embodiment provides a gas water heater, which includes a water heater housing 100 and a shielding assembly.

[0047] The shielding assembly includes a shield 200 and an extension plate 300. The shield 200 is detachably mounted on the bottom of the water heater housing 100. The shield 200 includes a main plate 210 and two side plates 220 connected to the main plate 210. The two side plates 220 are located on both sides of the width direction of the water heater housing 100. The extension plate 300 is arranged in a one-to-one correspondence with the side plates 220. The extension plate 300 is slidably mounted on the corresponding side plate 220 along the thickness direction of the water heater housing 100. A receiving cavity 201 is formed between the shield 200 and the two extension plates 300. In other words, a receiving cavity 201 is formed between the main plate 210, the two side plates 220, and the two extension plates 300. The receiving cavity 201 can accommodate the pipes connected to the gas water heater.

[0048] In this embodiment, for water heater shells 100 of different thicknesses, the extension plate 300 is slidable along the thickness direction of the water heater shell 100. This allows the extension plate 300 to protrude from the side panel 220 away from the main body plate 210 and align with the rear end of the water heater shell 100 (e.g., aligned with the rear edge of the side panel 110 of the water heater shell 100, or aligned with the back panel 120 of the water heater shell 100), and aligns the main body plate 210 with the front end of the water heater shell 100. This allows the shielding assembly to adapt to water heater shells of different thicknesses. The shielding assembly helps reduce the probability of gaps occurring due to the side panel 220 being too long along the thickness direction of the water heater shell 100, causing the main body plate 210 to misalign with the front end of the water heater shell 100. It also helps improve the shielding rate of the gas water heater's connecting pipes, giving the gas water heater a cleaner and more refined appearance.

[0049] For example, the shield 200 can be formed by bending sheet metal.

[0050] For example, the shield 200 may be U-shaped.

[0051] For example, the dimension of the shield 200 along the height direction of the water heater housing 100, that is, the height of the shield 200, can be 160mm-200mm, such as 170mm, 180mm or 190mm, which is beneficial for the shielding component to shield the pipes. Of course, the height of the shield 200 can also be other dimensions, which is not limited in this embodiment.

[0052] For example, the extension plate 300 can be a rectangular plate with rounded corners on all four sides, which effectively reduces the possibility of the main plate 210 cutting the user or damaging items.

[0053] For example, the length of the extension plate 300 protruding from the side panel 220 away from the main body plate 210 can be 60mm-80mm, such as 65mm, 70mm, 72mm or 75mm. Of course, the length of the extension plate 300 protruding from the side panel 220 away from the main body plate 210 can also be other dimensions, which are not limited in this embodiment.

[0054] For example, the included angle α between the main body plate 210 and the side cover plate 220 is ≥90°. When the main body plate 210 and the side cover plate 220 are perpendicular to each other, the gas water heater has a cleaner and more refined appearance, and the installation of the cover components is more convenient.

[0055] In this embodiment, reference is made to Figures 3 to 6 As shown, the side panel 220 is provided with a sliding groove, and the extension plate 300 slides into the sliding groove, which facilitates the assembly of the extension plate 300 onto the side panel 220 and helps to improve the stability of the extension plate 300 sliding relative to the side panel 220.

[0056] In one feasible implementation, the shield 200 further includes a first support portion 250, which is provided in a one-to-one correspondence with the side panel 220 of the shield. The first support portion 250 is located on the top of the corresponding side panel 220 and fits against the bottom of the water heater housing 100, which facilitates the positioning and assembly of the shield 200 on the bottom of the water heater housing 100 and effectively reduces the probability of the shield 200 scratching the water heater housing 100.

[0057] In one feasible implementation, the slide includes a first slide 2501, which is formed between the first support portion 250 and the cover side plate 220. The top of the extension plate 300 slides into the corresponding first slide 2501. In other words, the top of the extension plate 300 is sandwiched between the first support portion 250 and the corresponding cover side plate 220 to limit the top of the extension plate 300 along the width direction of the water heater shell 100. The sliding of the extension plate 300 is guided by the first slide 2501, which helps to improve the stability of the extension plate 300 sliding relative to the cover side plate 220.

[0058] Exemplarily, the first support portion 250 is formed by bending at least twice relative to the side panel 220. In some embodiments, the first support portion 250 includes a first plate portion 251, a second plate portion 252, a third plate portion 253, and a fourth plate portion 254, which are bent sequentially. The first plate portion 251 is connected to the corresponding side panel 220 and fits against the bottom of the water heater housing 100. The fourth plate portion 254 is parallel to the side panel 220 and forms a first groove 2501 between it and the side panel 220. It is understood that the extension plate 300 and the fourth plate portion 254 have a large contact area, which effectively reduces wear and facilitates the sliding of the extension plate 300.

[0059] For example, the first plate portion 251 is perpendicular to the cover side plate 220.

[0060] For example, the first plate portion 251 and the third plate portion 253 are parallel to each other, the second plate portion 252 and the fourth plate portion 254 are parallel to each other, and the first plate portion 251 and the second plate portion 252 are perpendicular to each other, which facilitates molding.

[0061] In one feasible embodiment, the shield 200 further includes a second support portion 260, which is correspondingly disposed with the side panel 220 of the shield. The second support portion 260 is bent at the bottom of the corresponding side panel 220. The sliding groove includes a second sliding groove 261, which is formed between the second support portion 260 and the corresponding side panel 220. The bottom of the extension plate 300 slides into the corresponding second sliding groove 261. The second sliding groove 261 guides the sliding of the extension plate 300, which helps to improve the stability of the sliding of the extension plate 300 relative to the side panel 220 and achieves the limiting of the bottom of the extension plate 300 along the width direction of the water heater shell 100, making it stable and reliable. In addition, the provision of the second support portion 260 can effectively reduce the occurrence of the side panel 220 cutting users or damaging items, and improve the structural strength of the shield 200.

[0062] For example, the shape of the second groove 261 can be set to U-shape.

[0063] For example, the shield 200 includes a first support portion 250 and a second support portion 260, that is, the slide includes a first slide 2501 and a second slide 261. The shield 200, through the arrangement of the first support portion 250 and the second support portion 260, is more conducive to the sliding of the extension plate 300 relative to the side plate 220 along the thickness direction of the water heater shell 100, which is stable and reliable.

[0064] In this embodiment, reference is made to Figure 1 , Figure 4 and Figure 5 As shown, the shield 200 also includes a third support 230, which is bent at the top of the main body plate 210 and fits against the bottom of the water heater shell 100 to facilitate the positioning and assembly of the shield 200, effectively reduce the probability of the shield 200 scratching the water heater shell 100, and improve the structural strength of the shield 200.

[0065] For example, the third support portion 230 may be flat. For example, the third support portion 230 is perpendicular to the main body plate 210.

[0066] For example, both ends of the third support portion 230 have a first inclined edge 231, and the end of the first plate portion 251 facing the main plate 210 has a second inclined edge 2511. The corresponding first inclined edge 231 and second inclined edge 2511 fit together, which is beneficial to maintain a stable relative angle between the main plate 210 and the cover side plate 220 and improve the structural strength of the shield 200.

[0067] In one feasible implementation, the bottom of the main body plate 210 is provided with a first folded edge 240, which bends into the receiving cavity 201, effectively reducing the occurrence of the main body plate 210 cutting the user or damaging the items, and improving the structural strength of the shield 200.

[0068] For example, the included angle β between the first folded edge 240 and the main body plate 210 is ≤90°.

[0069] In one feasible implementation, the extension plate 300 has a second folded edge 310 on the side away from the main body plate 210, and the second folded edge 310 is bent toward the receiving cavity 201. Exemplarily, the second folded edge 310 is perpendicular to the extension plate 300. In this embodiment, the second folded edge 310 can serve as a handle, allowing for easy adjustment of the length of the extension plate 300 protruding from the side panel 220 away from the main body plate 210 by pushing and pulling the extension plate 300. In some embodiments, the second folded edge 310 can be bent toward the outside of the receiving cavity 201.

[0070] In some embodiments, along the thickness direction of the water heater housing 100, the length of the cover side plate 220 is equal to the length of the shell side plate 110 of the water heater housing 100. The extension plate 300 on the cover 200 can be removed, or the extension plate 300 can be slid towards the main body plate 210 to its limit position before the cover 200 is installed on the bottom of the water heater housing 100. For example, as... Figure 7 In the gas water heater shown, the second folded edge 310 abuts against the corresponding first support part 250 and second support part 260.

[0071] In some embodiments, the second folded edge 310 can fit against the wall surface on which the water heater housing 100 is installed, which helps to shield the pipes from the components and gives the gas water heater a neater and more refined appearance.

[0072] In this embodiment, reference is made to Figure 1 , Figures 3 to 5 As shown, the water heater housing 100 and the shield 200 are magnetically or snap-fitted together for easy assembly. Of course, the water heater housing 100 and the shield 200 can also be fixed by bolts or other means, which is not limited in this embodiment.

[0073] In one feasible embodiment, the gas water heater further includes a magnetic component 400, which is disposed on at least one of the water heater housing 100 and the shield 200. The water heater housing 100 and the shield 200 are magnetically fixed by the magnetic component 400, which facilitates disassembly and assembly and is beneficial for the maintenance of the gas water heater and pipelines.

[0074] In some embodiments, both the water heater housing 100 and the shield 200 are provided with magnetic components 400. One of the magnetic components 400 on the water heater housing 100 and the magnetic component 400 on the shield 200 is a permanent magnet, and the other is made of a ferromagnetic material. For example, the magnetic component 400 on the water heater housing 100 is a permanent magnet, and the magnetic component 400 on the shield 200 is made of a ferromagnetic material. Of course, the two can also be interchanged; for example, the magnetic component 400 on the water heater housing 100 can be made of a ferromagnetic material, and the magnetic component 400 on the shield 200 can be a permanent magnet.

[0075] In some embodiments, both the water heater housing 100 and the shield 200 are provided with magnetic elements 400. The magnetic elements 400 on the water heater housing 100 and the magnetic elements 400 on the shield 200 are permanent magnets, and the magnetic elements 400 on the water heater housing 100 and the magnetic elements 400 on the shield 200 have opposite polarities so that they can attract each other.

[0076] In some embodiments, one of the water heater housing 100 and the shield 200 is provided with a magnetic member 400, and the other is made of a ferromagnetic material.

[0077] In some embodiments, the magnetic component 400 provided in the water heater housing 100 and the cover 200 is made of a ferromagnetic material, which is beneficial for the assembly and fixation of the magnetic component 400.

[0078] In the above embodiments, the permanent magnets are specifically common rubidium magnets, tungsten nickel cobalt magnets, ferrite magnets, etc., all of which are permanent magnets with their own magnetism; the ferromagnetic material parts are specifically common iron parts, cobalt parts, nickel parts, cobalt iron alloy parts, etc., all of which are ferromagnetic material parts that do not have their own magnetism but can be attracted by magnets.

[0079] In one feasible implementation, the magnetic member 400 includes a first magnetic member 410. A first support portion 250 is bent and forms a first mounting channel 2502 between itself and the corresponding side panel 220. Alternatively, the first support portion 250 is bent to form the first mounting channel 2502, and the first magnetic member 410 is disposed within the first mounting channel 2502. The shield 200 is magnetically fixed to the water heater housing 100 via the first magnetic member 410. It is understood that the shield 200 has first magnetic members 410 on both sides along the width direction of the water heater housing 100. The shield 200 and the water heater housing 100 are magnetically fixed via the first magnetic members 410, which facilitates a stable and reliable connection between the shield 200 and the water heater housing 100. Furthermore, the first magnetic member 410 being disposed within the first mounting channel 2502 effectively reduces the probability of the magnetic member 400 detaching from the shield 200.

[0080] For example, the first support 250 can not only cooperate with the second support 260 through the slide groove with the extension plate 300 to improve the sliding stability of the extension plate 300 relative to the cover side plate 220 along the thickness direction of the water heater shell 100; it can also serve as the carrier of the first magnetic member 410 through the first installation channel 2502, which is compact and helps to improve the structural strength of the shield 200.

[0081] For example, the first magnetic attractor 410 can be configured as a cuboid.

[0082] For example, taking the first support portion 250 as an example, which includes a first plate portion 251, a second plate portion 252, a third plate portion 253 and a fourth plate portion 254 arranged in sequence, a first installation channel 2502 is formed between the first plate portion 251, the second plate portion 252, the third plate portion 253 and the fourth plate portion 254.

[0083] For example, the first mounting channel 2502 has a rectangular cross-sectional shape to facilitate the insertion and positioning assembly of the first magnetic member 410.

[0084] For example, at least one first magnetic element 410 is provided in the first mounting channel 2502. For instance, two first magnetic elements 410 are arranged side by side in the first mounting channel 2502 along the thickness direction of the water heater housing 100 to improve the stability and reliability of the connection between the shield 200 and the water heater housing 100.

[0085] For example, the extension plate 300 is configured as a ferromagnetic plate and is magnetically attracted to the first magnetic attractor 410, which can effectively reduce the probability of the extension plate 300 detaching from the shield 200. When the extension plate 300 is slidably adjusted, the first magnetic attractor 410 magnetically attracts the extension plate 300, which helps to keep the extension plate 300 in the desired adjusted position.

[0086] In one feasible implementation, the magnetic member 400 includes a second magnetic member 420, which is disposed on the third support portion 230. The shield 200 is magnetically fixed to the shield 200 by the second magnetic member 420, which is beneficial to the fit between the third support portion 230 and the water heater housing 100, and improves the stability and reliability of the connection between the shield 200 and the water heater housing 100.

[0087] In some embodiments, the gas water heater further includes a support strip 500, a second magnetic member 420 embedded in the support strip 500, and two cover side plates 220 clamping and limiting the support strip 500 along the width direction of the water heater housing 100. In other words, the two ends of the support strip 500 abut against the corresponding side plates 220. The support strip 500 and the side of the third support portion 230 away from the water heater housing 100 are attached to each other and magnetically fixed to the cover 200 by the second magnetic member 420. The second magnetic member 420 is assembled onto the third support portion 230 by the support strip 500, which facilitates the positioning and assembly of the second magnetic member 420.

[0088] For example, the support strip 500 is glued to the third support portion 230, or fastened to the third support portion 230 by bolts, or fixed to the third support portion 230 by other connection methods. This embodiment is not limited.

[0089] For example, along the width direction of the water heater housing 100, a plurality of second magnetic elements 420 are embedded in the support strip 500 at intervals to improve the stability and reliability of the connection between the shield 200 and the water heater housing 100.

[0090] For example, the second magnetic member 420 can be configured as a cuboid.

[0091] For example, the support bar 500 has a hollow groove 510 on the side facing the third support portion 230, and the second magnetic member 420 is disposed in the hollow groove 510. It is understood that the hollow groove 510 and the second magnetic member 420 are arranged in a one-to-one correspondence to achieve positioning and assembly of the second magnetic member 420. In this embodiment, the second magnetic member 420 and the hollow groove 510 are interference-fitted to fix it to the support bar 500. Of course, the second magnetic member 420 can also be fixed to the support bar 500 by adhesive or other means; this embodiment does not limit this.

[0092] For example, the first support portion 250 and the main body plate 210 clamp the limiting support strip 500 along the thickness direction of the water heater shell 100, which facilitates the positioning and assembly of the second magnetic suction member 420 and reduces the probability of the support strip 500 disengaging from the third support portion 230. Taking the first support portion 250 as an example, which includes a first plate portion 251, a second plate portion 252, a third plate portion 253, and a fourth plate portion 254 that are bent in sequence, at least one of the second plate portion 252, the third plate portion 253, and the fourth plate portion 254 clamps the limiting support strip 500 with the main body plate 210 along the thickness direction of the water heater shell 100.

[0093] In some other embodiments, the gas water heater may not include the support bar 500, and the third support 230 is bent to form a second mounting channel (not shown), and the second magnetic member 420 is disposed in the second mounting channel.

[0094] For example, the magnetic component 400 includes a first magnetic component 410 and a second magnetic component 420. Both the first magnetic component 410 and the second magnetic component 420 are magnetically attracted to the bottom of the water heater housing 100, which is beneficial to the stability of the fit between the top of the shield 200 and the bottom of the water heater housing 100, and makes the connection between the shield 200 and the water heater housing 100 stable and reliable.

[0095] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0096] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
