Description

Technical Field

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

[0002] Water heaters are common household appliances, and the water tank is a crucial water storage component. The exterior of the water tank is usually fitted with a decorative cover to enhance its aesthetics. However, when the water tank is placed outdoors, external moisture such as rain or snow can easily seep in through the gap between the decorative cover and the outer shell. While some water tanks currently employ simple sealing structures for waterproofing, they still cannot completely prevent water from entering the inside of the decorative cover. This can lead to corrosion or short circuits in the electrical components inside the cover, affecting the tank's functionality. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a decorative cover assembly that can improve the waterproofness of electrical components and meet outdoor waterproofing requirements.

[0049] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0050] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, 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.

[0051] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0052] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0053] This application provides a decorative cover assembly and a water tank using the decorative cover assembly. The water tank is used in a water heater, which can be a floor-standing water heater or a wall-mounted water heater.

[0054] Please refer to Figures 1 to 3 The water tank 10 includes a housing 100 and a decorative cover assembly 200, which is mounted on the outer surface of the housing 100. The decorative cover assembly 200 includes a decorative cover body 210, which can cover some components required by the water tank 10, such as electrical components 220, between the housing 100 and the inner side of the decorative cover body 210, thereby improving the appearance of the water tank 10.

[0055] Since the decorative cover body 210 is connected to the outer shell 100, and the two are not a single piece, there will inevitably be installation gaps between the decorative cover body 210 and the outer shell 100. When the water tank is placed outdoors for use, external moisture such as rainwater and snowmelt can easily enter the containment space through the gaps between the decorative cover body and the outer shell. In related technologies, some water tanks have a sealing structure at the gap between the decorative cover body and the outer shell, such as a waterproof strip. However, the weather resistance of this sealing structure is poor and cannot meet the outdoor waterproof requirements. When the water tank is used in a complex and ever-changing outdoor environment for a long time, it is still difficult to prevent water from entering the inside of the decorative cover body, which can cause corrosion or short circuits to the internal components and affect the use of the water tank.

[0056] To address the above issues, please refer to the embodiments of this application. Figures 4 to 6The decorative cover body 210 includes an inner wall 211 (the inner wall 211 being the side wall of the decorative cover body 210 facing the outer shell 100) and a first water-blocking rib 212 and a second water-blocking rib 213 disposed on the inner wall 211. The first water-blocking rib 212 and the second water-blocking rib 213 are spaced apart, and the second water-blocking rib 213 surrounds at least a portion of the first water-blocking rib 212 along its circumference, that is, the second water-blocking rib 213 is located outside the first water-blocking rib 212. An electrical device 220 is disposed in the receiving space enclosed by the first water-blocking rib 212, and the electrical device 220 can be connected to the inner wall 211 of the decorative cover body 210.

[0057] The decorative cover assembly 200 also includes a rear cover 230, which is connected to the inner wall 211 of the decorative cover body 210 and covers the electrical device 220. The rear cover 230 includes a side peripheral wall 231 that abuts against the inner wall 211, and at least a portion of the side peripheral wall 231 is located between the first water-blocking rib 212 and the second water-blocking rib 213.

[0058] Understandably, the first water-retaining rib 212, the second water-retaining rib 213, and the rear cover 230 form three lines of defense. Specifically, for water entering through the gap between the decorative cover body 210 and the outer shell 100, the second water-retaining rib 213 provides the first layer of waterproofing, preventing water from flowing into the inner side of the rear cover 230; the side wall 231 of the rear cover 230 provides the second layer of waterproofing, preventing water from flowing towards the first water-retaining rib 212; and the first water-retaining rib 212 provides the third layer of waterproofing, preventing water from entering the containment space. Therefore, with the above settings, if water entering the inner side of the decorative cover body 210 wants to enter the containment space, it must overcome the obstruction of the second water-blocking rib 213, the side wall 231 of the rear cover 230, and the first water-blocking rib 212 in sequence. The flow path is long and requires multiple turns, which greatly increases the difficulty for water to enter the containment space and affect the electrical components 220, effectively improving the waterproof effect and meeting the outdoor waterproof requirements.

[0059] The first water-blocking rib 212 and the second water-blocking rib 213 can be connected to the inner wall 211. For example, the first water-blocking rib 212 and the second water-blocking rib 213 can be heat-fused to the inner wall 211. Alternatively, the first water-blocking rib 212 and the second water-blocking rib 213 can also be integrally formed with the inner wall 211.

[0060] The first water-blocking rib 212 can be constructed as a closed ring structure or as an open ring structure.

[0061] In some embodiments, the second water-blocking rib 213 is constructed as a non-closed ring structure with an open bottom end. It is understood that a non-closed ring structure is an open-loop structure. For ease of explanation, refer to... Figure 6As shown, the bottom wall of the side peripheral wall 231 is defined as the first wall 2311, and the other part of the side peripheral wall 231 excluding the first wall 2311 is defined as the remaining wall 2312. The remaining wall 2312 is located between the first water-blocking rib 212 and the second water-blocking rib 213. That is, the second water-blocking rib 213 only surrounds one side of the remaining wall 2312 of the back cover 230. Since the bottom opening of the second water-blocking rib 213 is not closed, the first wall 2311 is not surrounded by the second water-blocking rib 213. That is, the bottom side (lower side) of the first wall 2311 is not blocked by the second water-blocking rib 213. In this way, if some water enters from the gap between the decorative cover body 210 and the outer shell 100 and falls onto the back cover 230, the water can flow down the back cover 230 and drain away under the action of gravity, instead of accumulating at the bottom of the back cover 230. This avoids the subsequent formation of water vapor and its impact, and further improves the waterproof effect.

[0062] In some embodiments, please refer to the reference Figure 4 and Figure 7 The second water-retaining rib 213 includes a second rib 2132 and two first ribs 2131. Both first ribs 2131 extend along a first direction and are respectively disposed on opposite sides of the rear cover 230 along a second direction. The first direction is parallel to the height direction of the decorative cover body 210, and the second direction is parallel to the width direction of the decorative cover body 210. The second rib 2132 connects the two first ribs 2131 and is located on the top side of the rear cover 230.

[0063] The second rib 2132 is provided on the top side (i.e., the upper side) of the rear cover 230, and the two first ribs 2131 are respectively provided on the left and right sides of the rear cover 230. The second rib 2132 blocks and guides the water flowing down from the upper end of the decorative cover body 210, preventing water from entering the inner side of the rear cover 230 through the gap between the rear cover 230 and the inner wall 211. At the same time, it guides the water flow to the first ribs 2131 on the left and right sides. The two first ribs 2131 can block the water flowing from the left and right sides of the rear cover 230 from entering the rear cover 230 and guide the water flow downwards.

[0064] In some embodiments, please refer to the reference Figure 5 and Figure 7 The second rib 2132 includes a first end 2132d and a second end 2132e that are opposite to each other along its length. The first end 2132d and the second end 2132e are respectively connected to two first ribs 2131. The height of the second rib 2132 relative to the electrical device 220 increases and then decreases from the first end 2132d to the second end 2132e.

[0065] As is easily understood, the height of the second rib 2132 relative to the electrical component 220 refers to the vertical distance from various points of the second rib 2132 along the height direction of the water tank 10 to the same horizontal reference plane on the electrical component 220. The height of the second rib 2132 relative to the electrical component 220 first increases and then decreases from the first end 2132d to the second end 2132e. This means that the vertical distance between the two ends of the second rib 2132 and the electrical component 220 is small, while the vertical distance between the middle of the second rib 2132 and the electrical component 220 is large. Furthermore, along the direction from the end of the second rib 2132 to its highest point in the middle, the vertical distance between the second rib 2132 and the electrical component 220 gradually increases. In other words, the middle of the second rib 2132 is high, and the two ends are low. When water flowing down from the top of the decorative cover body 210 reaches the second rib 2132, the water has downward kinetic energy due to gravity, allowing it to flow faster and better to the first ribs 2131 on both sides. In other words, the second rib 2132 can guide the water to drain quickly to both ends, preventing large amounts of water from overflowing from the second rib 2132 and falling onto the back cover 230 due to obstruction. This reduces the risk of water overflowing and intruding between the back cover 230 and the inner wall 211, further improving the waterproof effect. At the same time, the water flowing to the second rib 2132 is easier to drain completely, preventing water from accumulating at the second rib 2132.

[0066] The overall shape of the second rib 2132 can be set as an inverted V-shape, a semi-circle, or a semi-ellipse, as long as it is high in the middle and low at both ends. The accompanying drawings of this application are only illustrative of the first rib 2131 being set as an inverted V-shape, and should not be regarded as a limitation of this application.

[0067] In some embodiments, please refer to Figure 6 At least a portion of the second ribs 2132 are opposite to and spaced apart from the inner wall 211, so that the second ribs 2132 and the inner wall 211 form a first water-blocking groove 2132c.

[0068] In some special environments, such as when it is raining heavily outdoors, the water flowing down from the top of the decorative cover body 210 is accelerated by gravity and has a large flow velocity when it reaches the second rib 2132. Moreover, the water continuously converges as it flows down, and the water volume is large when it reaches the second rib 2132. In this embodiment, at least a portion of the structure of the second rib 2132 is spaced apart from the inner wall 211, so that the second rib 2132 and the inner wall 211 enclose a first water-blocking groove 2132c. When water flows downward to the second rib 2132, the portion of the second rib 2132 opposite to the inner wall 211 can block the water flow, preventing the water from overflowing due to collision at high speed. At the same time, the first water-blocking groove 2132c has a depth, which can temporarily store water for a short time, preventing large water flows from overflowing due to inability to drain in time. Thus, through the above design, this embodiment can effectively avoid the situation where large water flows overflow from the second rib 2132 to the back cover 230, greatly reducing the risk of water intrusion between the back cover 230 and the inner wall 211, and further improving the waterproof effect.

[0069] The structure in which the second rib 2132 and the inner wall 211 form a storage compartment can be varied. For example, the second rib 2132 can be configured such that one end is connected to the inner wall 211 and the other end extends obliquely away from the inner wall 211.

[0070] In one embodiment, please continue to refer to Figure 6 The second rib 2132 includes a first water-blocking plate 2132a and a second water-blocking plate 2132b. The first water-blocking plate 2132a is connected to the inner wall 211, and the second water-blocking plate 2132b is connected to the end of the first water-blocking plate 2132a away from the inner wall 211 and is arranged opposite to the inner wall 211. At this time, the cross section of the second rib 2132 is L-shaped. The second water-blocking plate 2132b, the first water-blocking plate 2132a and the inner wall 211 enclose and form the first water-blocking groove 2132c.

[0071] In other embodiments, to further improve the waterproofing effect, at least some of the first ribs 2131 may also be arranged opposite to and spaced apart from the inner wall 211, so that the first ribs 2131 and the inner wall 211 form a second water-blocking groove, which will not be described in detail here.

[0072] In one embodiment, the electrical device 220 includes a display device 221, which may include a display portion and an electronic control portion connected to the display portion. Please refer to... Figure 2 and Figure 8The decorative cover body 210 has an opening 219 extending along its thickness direction, through which at least a portion of the display device 221 is exposed. The decorative cover assembly 200 also includes a light-transmitting plate 240, which is sealed to the decorative cover body 210 and covers the opening 219. By providing the light-transmitting plate 240 to cover the opening 219 and sealing it to the decorative cover body 210, water on the outer wall 214 of the decorative cover body 210 (i.e., the side wall of the decorative cover body 210 facing away from the outer casing 100) can be prevented from flowing into the decorative cover body 210 through the opening 219, thus avoiding affecting the normal operation of the display device 221. This achieves external waterproofing and further improves the waterproofing effect.

[0073] The light-transmitting plate 240 is made of weather-resistant materials, such as glass.

[0074] In one embodiment, please refer to Figure 6 and Figure 8 The outer wall 214 of the decorative cover body 210 is provided with a mounting groove 215, which communicates with the opening 219. A light-transmitting plate 240 is disposed within the mounting groove 215 and is bonded to the groove wall of the mounting groove 215 with sealant. The mounting groove 215 includes a bottom wall and side walls. The opening 219 penetrates the bottom wall. The sealant can be placed between the light-transmitting plate 240 and the bottom wall, and / or between the light-transmitting plate 240 and the side wall. The sealant can be a waterproof and weather-resistant adhesive.

[0075] In this embodiment, through the above-described configuration, on the one hand, by installing the light-transmitting plate 240 within the mounting groove 215, the light-transmitting plate 240 can be flush with the outer wall 214 surface of the decorative cover body 210, avoiding visual abruptness and further improving the appearance of the decorative cover assembly 200. On the other hand, with the light-transmitting plate 240 installed within the mounting groove 215, if external water wants to enter the decorative cover body 210, it needs to flow through the gap between the light-transmitting plate 240 and the groove wall of the mounting groove 215, increasing the distance the water needs to travel and requiring at least two bends, significantly increasing the difficulty of water entry; moreover, the light-transmitting plate 240 is bonded to the groove wall of the mounting groove 215 with sealant, effectively blocking water from entering through the gap between the light-transmitting plate 240 and the mounting groove 215, ensuring a waterproof effect.

[0076] In some embodiments, the decorative cover body 210 is provided with mounting holes, and the decorative cover body 210 is fixed to the housing 100 by fasteners passing through the mounting holes. To reduce the number of openings in the decorative cover body 210, please refer to... Figure 9The water tank 10 also includes an inner fixing plate 300, which is fixed to the outer shell 100. The decorative cover body 210 is indirectly fixed to the outer shell 100 through the inner fixing plate 300. Specifically, the decorative cover body 210 may be provided with a first buckle (not shown) on the side facing the inner fixing plate 300, and the inner fixing plate 300 is provided with a first slot (not shown). The decorative cover body 210 is snapped onto the inner fixing plate 300 through the first buckle and the first slot. In this way, by snapping the decorative cover body 210 onto the inner fixing plate 300, and using fewer fasteners, the connection between the decorative cover body 210 and the inner fixing plate 300 can be ensured to be firm, thereby reducing the number of openings on the decorative cover body 210 and improving the appearance.

[0077] In one embodiment, please refer to the reference Figure 2 , Figure 10 and Figure 11 The top of the decorative cover body 210 is provided with a mounting hole 216, and the top of the inner fixing plate 300 is provided with a connecting hole 310. The connecting hole 310 corresponds to the mounting hole 216. Fasteners are inserted through the mounting hole 216 and the connecting hole 310. The decorative cover body 210 is fixed to the inner fixing plate 300 by the fasteners, thereby indirectly fixing the decorative cover body 210 to the outer shell 100 through the inner fixing plate 300.

[0078] The mounting hole 216 is constructed as a stepped hole, comprising a first hole 2161, a second hole 2162, and a stepped portion 2163 formed on one side of the first hole 2161. The first hole 2161 communicates with the outside of the decorative cover body 210, and the second hole 2162 penetrates the stepped portion 2163. By setting the mounting hole 216 as a stepped hole, the fastener can be hidden inside the mounting hole 216, making it difficult for the user to directly see the fastener from the outside, thus improving the appearance.

[0079] In one embodiment, the decorative cover body 210 is further provided with a first drainage hole 217, which is located on the periphery of the second hole 2162 and extends through the step portion 2163. By providing the first drainage hole 217, water at the mounting hole 216 can flow into the decorative cover body 210 and flow downward along the inner fixing plate 300, preventing water from accumulating at the mounting hole 216 and causing corrosion damage to the fasteners, and preventing subsequent difficulty in disassembling the fasteners, which would affect the maintenance of the decorative cover assembly 200.

[0080] Please refer to Figure 4The bottom of the decorative cover body 210 is provided with a second drain hole 218 that extends along its thickness direction. Water entering the inside of the decorative cover body 210 will flow downwards under the influence of gravity until it flows to the second drain hole 218 and is discharged. Understandably, the second drain hole 218 is located at the lowest point of the decorative cover body 210, which can achieve rapid drainage and prevent water from accumulating at the bottom of the decorative cover body 210.

[0081] The decorative cover assembly 200 and water tank 10 provided in this application, through the waterproof structure of the above embodiments, greatly improve the waterproof effect. According to the applicant's test, they can meet the outdoor use requirements of IPX4 waterproof rating.

[0082] The water tank 10 of this embodiment includes a shell 100 and a decorative cover assembly 200 mounted on the shell 100. The decorative cover assembly 200 includes a decorative cover body 210, an electrical component 220, and a rear cover 230. The decorative cover body 210 includes an inner wall 211 and a first water-blocking rib 212 and a second water-blocking rib 213 disposed on the inner wall 211. The first water-blocking rib 212 forms an accommodating space, and the first water-blocking rib 212 and the second water-blocking rib 213 are spaced apart. The second water-blocking rib 213 surrounds at least a portion of the first water-blocking rib 212. The electrical component 220 is disposed in the accommodating space. The rear cover 230 is connected to the inner wall 211 of the decorative cover body 210 and covers the electrical component 220. The rear cover 230 includes a side peripheral wall 231 that abuts against the inner surface, and at least a portion of the side peripheral wall 231 is located between the first water-blocking rib 212 and the second water-blocking rib 213. Therefore, for water entering through the gap between the decorative cover body 210 and the outer shell 100, the second water-blocking rib 213 provides the first layer of waterproofing, preventing water from flowing into the inner side of the rear cover 230; the side wall 231 of the rear cover 230 provides the second layer of waterproofing, preventing water from flowing towards the first water-blocking rib 212; and the first water-blocking rib 212 provides the third layer of waterproofing, preventing water from entering the containment space. Through the three layers of blocking action of the second water-blocking rib 213, the side wall 231 of the rear cover 230, and the first water-blocking rib 212, the difficulty of water entering the containment space and affecting the electrical components 220 is significantly increased, effectively improving the waterproofing effect. This meets outdoor waterproofing requirements, can cope with complex outdoor environments, and ensures that the electrical components 220 of the water tank 10 are always in a good waterproof environment, guaranteeing the normal and stable use of the water tank 10.

[0083] This application also provides a water heater, which includes a water tank 10 based on any of the above embodiments.

[0084] Since the water heater adopts all the technical solutions of the water tank 10 in the above embodiments, it has at least all the beneficial effects brought about by the technical solutions in the above embodiments.

[0085] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
