Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to a front shell assembly for a water heater and a water heating device. Background Technology

[0002] Water heaters, as a type of household hot water device, are mainly used in kitchens or bathrooms to provide instant hot water, thus solving the problem of cold water when washing dishes, vegetables, or hands in winter. Based on the heating method, water heaters are mainly divided into two types: storage-type and instantaneous-type.

[0003] A water heater consists of an outer shell and an inner tank, with a foaming space between them filled with expanding foam material. Some existing water heaters have a large first mounting surface on the outer wall of the front shell for installing decorative elements such as glass. Because the foaming space corresponding to this first mounting surface within the shell is relatively large, a significant amount of expanding foam material is required. However, as this large amount of foam material cools, it causes significant shrinkage and deformation at the first mounting surface, resulting in sagging. This reduces the flatness of the first mounting surface, ultimately affecting the difficulty of installing decorative elements and the stability after installation. Utility Model Content

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0042] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0044] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0045] This utility model discloses a front shell assembly for a water heater. The front shell assembly is an important component of the outer shell structure of the water heater. A sealed chamber can be formed between the outer shell structure and the inner tank of the water heater. This sealed chamber is a foaming chamber that needs to be filled with foaming material. A partial foaming chamber is formed between the front shell assembly and the inner tank of the water heater.

[0046] like Figures 1 to 4As shown, the front shell assembly of the water heater includes a front shell component 10 and a decorative panel (not shown in the figure). The front shell component 10 includes a front panel 100 and a boss structure 200. The front panel 100 is the panel facing forward after the water heater is installed in place. The front panel 100 includes a first mounting portion 110, and at least a portion of the outer wall surface of the first mounting portion 110 forms a first mounting surface 111. The first mounting surface 111 is used to install the decorative panel. It should be noted that the decorative panel serves a decorative function to improve the appearance of the water heater. Optionally, the decorative panel is a glass panel. The boss structure 200 is connected to the inner wall surface of the first mounting portion 110 or is formed by a portion of the structure of the first mounting portion 110 protruding inward. That is, the boss structure 200 and the front panel 100 can be integrally molded parts or independent structures that are fixed by subsequent connection. The front shell component 10 has an assembled state with the inner tank. In the assembled state, a flow gap is formed between the boss structure 200 and the outer wall surface of the inner tank for the foaming material to flow through. Regarding the flow clearance, it refers to the gap between the boss structure 200 and the outer wall surface of the inner liner in the radial direction.

[0047] The water heater front shell assembly disclosed in this utility model has a boss structure 200 provided on the first mounting part 110 of the front shell 10 for mounting decorative panels. On the one hand, the boss structure 200 is a solid structure, which can reduce the size of the foaming space between the front shell 10 and the inner tank, thereby reducing the amount of foaming material used and thus reducing the degree of deformation of the first mounting surface 111 caused by the cooling of the foaming material. On the other hand, the boss structure 200 can improve the structural strength of the front shell 10 itself, which is also conducive to reducing the degree of deformation of the first mounting surface 111. The combination of the two aspects not only allows the decorative panels to be quickly installed on the first mounting surface 111, but also improves the installation quality of the decorative panels.

[0048] Regarding the specific structure of the front shell 10, please refer to... Figure 2 As shown, in addition to the front panel 100, the front housing 10 also includes side wall panels 300, which protrude along the edge of the front panel 100. In some embodiments, multiple side wall panels 300 are provided and protrude at least circumferentially along the front panel 100. In one specific embodiment, the front panel 100 is a rectangular plate, and three side wall panels 300 are provided: an upper side wall panel, a lower side wall panel, and a left side wall panel. The upper side wall panel is located on the upper side of the front panel 100, the lower side wall panel is located on the lower side of the front panel 100, and the left side wall panel is located on the left or right side of the front panel 100. Of course, in other embodiments, the number of side wall panels 300 can be increased or decreased as needed.

[0049] In addition to the front housing assembly of the water heater, the housing structure also includes a rear housing component for mounting on the rear side of the front housing component 10. In some embodiments, the rear housing component and the front housing component 10 are screwed together. For example, a stud structure 310 with a threaded hole is provided on the side wall plate 300, and a mating structure with a through hole is also provided on the rear housing component of the water heater. Screws pass through the through hole on the mating structure and the threaded hole on the stud structure 310 to achieve the screwing connection between the front housing component 10 and the rear housing component of the water heater. Of course, in other embodiments, the rear housing component and the front housing component 10 can also be connected in other ways, such as snap-fit, or two or more connection methods can be used, such as a combination of snap-fit ​​and screw connection, to improve assembly stability.

[0050] Continue to refer to Figure 2 As shown, the front housing 10 may also have a side opening 400, which can be either a left or right side opening. The water heater front housing assembly also includes a service cover, which is detachably connected to the side opening 400. The detachable connection method includes, but is not limited to, connector connection, snap-fit, and magnetic attraction. Providing a separate and detachably connected service cover makes it easier to perform maintenance on the water heater.

[0051] Continue to refer to Figure 2 As shown, the boss structure 200 includes a plurality of protrusions 210 arranged in rows and columns, with a flow channel 212 formed between adjacent rows and / or adjacent columns of protrusions 210 for the foaming material to flow through. The flow channel 212 ensures that the boss structure 200 does not affect the movement of the foaming material within the foaming cavity, allowing the foaming material to fill the foaming cavity evenly. In one embodiment, the boss structure 200 includes three rows and five columns of protrusions 210; of course, in other embodiments, the number of rows and columns of protrusions 210 can be increased or decreased as needed. In addition, besides being arranged in rows and columns, the protrusions 210 can be arranged in a ring or other arrangements.

[0052] In some embodiments, the boss structure 200 is located at the middle position of the first mounting portion 110 to primarily enhance the structural strength of the middle position of the first mounting portion 110. It should be noted that the middle position of the first mounting surface 111 is also the position most prone to shrinkage deformation. Placing the boss structure 200 at the middle position of the first mounting portion 110 can effectively reduce the probability of deformation at the middle position of the first mounting surface 111.

[0053] In some embodiments, at least a portion of the protrusion 210 has an arc-shaped end face 211 near the inner liner. When the inner liner is a cylindrical structure, setting the end face 211 of the protrusion 210 to an arc-shaped surface makes the end face 211 more compatible with the arc-shaped outer wall surface of the inner liner, and a flow gap with a basically consistent width is formed between the two arc-shaped surfaces, which is more conducive to the smooth and fast passage of the foaming material through the flow gap.

[0054] like Figure 5 and Figure 6 As shown, the water heater front housing assembly also includes a control panel 20, which is mounted on the front panel 100. In some embodiments, for mounting the control panel 20, reference continues to be made to... Figure 1 As shown, the front panel 100 also includes a second mounting portion 120, which is disposed adjacent to the first mounting portion 110. A first mounting groove 121 for mounting the control panel 20 is formed on the second mounting portion 120.

[0055] Compared to related technologies where a dedicated panel mounting structure is used to install the control panel on the water heater, and the panel mounting structure is then assembled with the front shell after the control panel is installed on the panel mounting structure, in this utility model, a second mounting part 120 is provided on the front panel 100, so that the control panel 20 can be directly installed on the front shell 10, which is beneficial to improving the appearance of the water heater and the assembly efficiency.

[0056] In some embodiments, the control panel 20 is placed in the first mounting groove 121 and slidably engaged with the second mounting part 120. Optionally, a plurality of first slot structures 129 with the same opening direction are provided in the circumferential direction of the first mounting groove 121, and a plurality of first protrusion structures 205 with the same protrusion direction are provided in the circumferential direction of the control panel 20. After the control panel 20 is placed in the first mounting groove 121, the first protrusion structures 205 and the first slot structures 129 are first misaligned, and then the control panel 20 is moved horizontally, so that all the first protrusion structures 205 simultaneously enter the corresponding first slot structures 129, and the engagement is completed after moving a certain distance. Of course, the positions of the first slot structures 129 and the first protrusion structures 205 can also be interchanged, that is, the first slot structures 129 are placed on the control panel 20, and the first protrusion structures 205 are placed in the first mounting groove 121.

[0057] In one specific embodiment, the first latching protrusion 205 is generally L-shaped. The vertical portion of the first latching protrusion 205 is connected to the control panel 20, and the horizontal portion of the first latching protrusion 205 is used to insert into the first latching slot structure 129. In another specific embodiment, the front panel 100 is provided with a first latching slot structure 129, which is generally L-shaped. The vertical slot of the first latching slot structure 129 has openings at the top and sides, while the horizontal slot of the first latching slot structure 129 has an opening only at the side. The first latching protrusion 205 can enter through the top opening of the vertical slot and be engaged into the horizontal slot by movement. Of course, in other embodiments, the first latching slot structure 129 can also be a combination of a sliding groove and a latching hole, with the first latching protrusion 205 first entering the sliding groove and then being engaged into the latching hole by movement.

[0058] In some embodiments, in a first direction perpendicular to the sliding insertion direction, the first slot structure 129 has two rows, and the two rows of first slot structures 129 are respectively disposed on both sides of the first mounting groove 121. Correspondingly, the first protrusion structure 205 also has two rows, and the two rows of first protrusion structures 205 are respectively disposed on both sides of the control panel 20. In the sliding insertion direction, the end of the first mounting groove 121 may also be provided with the first slot structure 129, and the end of the control panel 20 may also be provided with the first protrusion structure 205. It should be noted that the sliding insertion direction can be the length direction of the front shell 10 and the control panel 20, then the first direction perpendicular to the sliding insertion direction is the width direction of the front shell 10 and the control panel 20.

[0059] In some embodiments, the second mounting part 120 is provided with a first insertion hole 123 and a first snap-fit ​​rib 124, and the control panel 20 is provided with a first snap-fit ​​member 201 and a limiting member 202 spaced apart. The side of the first snap-fit ​​member 201 facing away from the limiting member 202 forms a limiting slot 2011. The first snap-fit ​​member 201 is inserted into the first insertion hole 123, and the first snap-fit ​​rib 124 is inserted into the limiting slot 2011. The limiting member 202 can be squeezed into the first insertion hole 123 and limit and abut against the inner side of the first insertion hole 123.

[0060] In one specific embodiment, in the sliding insertion direction, the first insertion hole 123 and the first snap-fit ​​rib 124 are provided at one end of the second mounting part 120, and the first insertion hole 123 and the first snap-fit ​​rib 124 are located on the starting end side; the first snap-fit ​​member 201 and the limiting member 202 are provided at the corresponding end of the control panel 20.

[0061] In one specific embodiment, the first insertion hole 123 is a rectangular hole, and the distance between the first snap-fit ​​member 201 and the limiting member 202 is approximately equal to the length of the rectangular hole. In one specific embodiment, the limiting member 202 includes a plurality of spaced-apart limiting ribs; exemplarily, three limiting ribs are provided. The farthest distance between the limiting ribs located at both ends is approximately equal to the width of the first insertion hole 123.

[0062] In some embodiments, the second mounting portion 120 is provided with a second insertion hole 125 and a second snap-fit ​​rib 126, and the control panel 20 is provided with a second snap-fit ​​member 203. The second snap-fit ​​member 203 passes through the second insertion hole 125 and snaps into the second snap-fit ​​rib 126. Optionally, the extension direction of the second snap-fit ​​rib 126 is perpendicular to the extension direction of the first snap-fit ​​rib 124, such that the snap-fit ​​limiting direction of the first snap-fit ​​rib 124 and the first snap-fit ​​member 201 is perpendicular to the snap-fit ​​limiting direction of the second snap-fit ​​rib 126 and the second snap-fit ​​member 203. For example, if one of the snap-fit ​​limiting directions is the length direction of the control panel 20, then the other is the width direction of the control panel 20.

[0063] In some embodiments, the second mounting portion 120 is provided with a third insertion hole 127 and a third snap-fit ​​rib 128, and the control panel 20 is provided with a third snap-fit ​​member 204, which passes through the third insertion hole 127 and snaps into the third snap-fit ​​rib 128. Optionally, the extending direction of the second snap-fit ​​rib 126 is parallel to the extending direction of the third snap-fit ​​rib 128.

[0064] To improve the stability of the inner tank within the outer shell structure, the front shell assembly of the water heater also includes an inner tank support (not shown in the figure). The front shell 10 has an installation space, and the inner tank support is located within the installation space and is used to support the end of the inner tank.

[0065] In some embodiments, the inner liner is cylindrical, and an arc-shaped limiting groove is formed on the inner liner support member. The end of the inner liner is limited in the arc-shaped limiting groove. The arc-shaped support surface of the arc-shaped limiting groove fits more closely with the arc-shaped outer wall surface of the cylindrical inner liner, resulting in better support stability.

[0066] In some embodiments, there are two or more arc-shaped limiting grooves, each of which can support and limit the inner liner. For example, there are two arc-shaped limiting grooves.

[0067] The inner liner support is detachably connected to the front shell 10. In some embodiments, the front shell 10 and the inner liner support are snap-fitted together. For example, the front shell 10 has a second snap-fit ​​protrusion 150, and the inner liner support has a second snap-fit ​​groove structure. The second snap-fit ​​protrusion 150 can snap into the second snap-fit ​​groove structure. Of course, in addition to snap-fitting, other detachable connection methods can also be used, such as magnetic attraction or connector connection.

[0068] In some embodiments, one of the inner wall surface of the front shell 10 and the inner liner support is provided with a limiting groove or a limiting surface, and the other is provided with a limiting protrusion 140. The limiting protrusion 140 is limited in the limiting groove, or the limiting surface is limited and abuts against the limiting protrusion 140.

[0069] To reduce the assembly difficulty of the inner liner support and the front shell 10 and improve assembly efficiency, a combination of snap-fit ​​and limiting fit is used. In some embodiments, multiple second snap-fit ​​structures 150 and multiple limiting protrusions 140 are arranged on the inner wall surface of the front shell to form an annular structure, and the shape of the annular structure is roughly the same as the shape of the inner liner support. The multiple second snap-fit ​​structures 150 can snap a part of the inner liner support, and the multiple limiting protrusions 140 can limit other parts of the inner liner support.

[0070] For example, the inner liner support is generally L-shaped, and the three continuous sides of the inner liner support form a limiting surface. The inner wall of the front shell 10 is provided with limiting protrusions 140 arranged in a general U-shape, and the limiting protrusions 140 abut against the corresponding limiting surface. The other three continuous sides of the inner liner support are provided with second slot structures, and the inner wall of the front shell 10 is provided with second locking protrusion structures 150 arranged in a general U-shape, and the second locking protrusion structures 150 are engaged in the corresponding second slot structures.

[0071] Furthermore, the front shell 10 and the inner liner support are connected via a connector. Optionally, both the front shell 10 and the inner liner support are provided with screw holes 160, and the front shell 10 and the inner liner support are connected by screws passing through the screw holes 160. The front shell 10 and the inner liner support are assembled through three methods: limiting fit, snap-fit, and connector connection, resulting in better stability.

[0072] In some embodiments, two inner liner supports are provided, spaced apart within the front shell 10, and respectively used to support the two ends of the inner liner. Optionally, if there are two or more inner liners, each inner liner support can support at least two inner liners. It should be noted that if there are two or more inner liners, each inner liner support can also support all inner liners located on the same side end.

[0073] If the number of inner tanks is two or more, the front shell assembly of the water heater also includes an inner tank divider. The inner tank divider is disposed within the installation space and is used to divide the installation space into multiple sub-spaces, each sub-space being used to confine one inner tank. In one embodiment, the inner tank divider is approximately figure-eight shaped. In one embodiment, there are two or more inner tank dividers arranged in at least one row.

[0074] Continue to refer to Figure 1 As shown, the front housing 10 also includes a third mounting portion 130, which is formed between the first mounting portion 110 and the second mounting portion 120. A second mounting surface 122 is formed on the third mounting portion 130, which is used to mount a decorative strip, thereby improving the appearance of the water heater front housing assembly. Optionally, a second mounting groove is provided on the third mounting portion 130, which is used to mount the decorative strip.

[0075] Continue to refer to Figure 1 As shown, the front housing 10 is also provided with a microphone hole 500 and a speaker hole 600. Inside the front housing 10, there is a microphone corresponding to the microphone hole 500 and a speaker corresponding to the speaker hole 600. The microphone and speaker work together to enable the water heater to have a voice function.

[0076] This utility model also discloses a hot water device, which includes an outer shell structure and an inner tank. The inner tank is installed inside the outer shell structure, and the outer shell structure includes the aforementioned front shell assembly and rear shell component of the water heater. By using the aforementioned front shell assembly, the appearance and quality of the hot water device are greatly improved, and the probability of decorative panels warping, bulging, or even falling off is reduced.

[0077] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
