[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0034] With reference to Figs. 1 to 3 The water supply device provided by the embodiment of the present application is convenient to assemble, which comprises a shell 10 and an assembly component arranged in the shell 10. The assembly component comprises a hot pot 20 and a support 30 for fixing the hot pot 20. At least one side of the shell 10 is provided with a mounting plate which can be opened / closed relative to the shell. A sliding fit structure is arranged between the shell 10 and the support 30, so that the support 30 can drive the assembly component to be pushed into or pulled out of the shell 10 from the mounting plate.

[0035] Specifically, in the embodiment, the shell 10 is in the shape of a cuboid box, and specifically is enclosed by a top plate 11, a bottom plate 12, two side plates 13, a front plate 14 and a back plate (not shown in the figure). The heat tank 20 is also in the shape of a cuboid, and thus the shape and size of the shell 10 match those of the heat tank 20, so that the heat tank 20 can be better placed in the shell 10. In the embodiment, the back plate can be opened / closed relative to the shell 10, and when the back plate is opened, the assembly component can be pushed into the shell 10 or pulled out of the shell.

[0036] In the embodiment, the back plate is set to be movable, and can be opened or closed relative to the shell 10, which facilitates the assembly of the heat tank 20 and the support 30 from the back side. The sliding fit structure between the support 30 and the shell 10 enables the heat tank 20 to enter and exit the shell 10 by using the sliding fit structure, so that the entire heat tank 20 does not need to be lifted, and the pushing and pulling are more labor-saving and time-saving. This structure also facilitates the maintenance and detection of the heat tank 20. Of course, other side plates can also be set to be movable and openable / closable.

[0037] Specifically, the sliding fit structure includes a sliding guide rail 121 provided on the bottom plate 12 and a sliding block 31 provided at the bottom of the support 30 and slidable on the sliding guide rail 121. The cooperation of the sliding block 31 and the sliding guide rail 121, on the one hand, makes the movement of the heat tank 20 and the support 30 in the shell 10 more labor-saving, and on the other hand, the sliding block 31 is clamped on the guide rail, which also plays a role in fixing and limiting the support 30 and the heat tank 20, so as to avoid the left and right displacement of the heat tank 20 and the support 30 in the shell 10 during transportation or carrying.

[0038] The structure of the sliding block 31 and the sliding guide rail 121 can be various, and the cross section of the sliding block 31 and the sliding guide rail 121 can be rectangular, V-shaped, circular or dovetail-shaped, etc. Among them, the rectangular sliding block and sliding rail structure are simple, easy to manufacture, detect and maintain. And the rectangular linear guide rail can be made wider, with greater carrying capacity and rigidity. When the sliding guide rail 121 and the sliding block with a rectangular cross section are used, one can be provided at the center of the bottom of the support 30. Of course, two sliding guide rails 121 can also be symmetrically provided on the bottom plate 12 of the shell 10, and correspondingly two sliding blocks 31 are provided at the bottom of the support 30. Of course, in order to make the support 30 more stable when supporting the heat tank 20, four sliding blocks 31 can be provided at the bottom of the support 30. When the support 30 and the heat tank 20 are placed in the shell 10, the four sliding blocks 31 are located at the four corners of the bottom of the heat tank 20, which also plays a role in corner cushioning, so that the heat tank 20 is placed more stably. Of course, the sliding block 31 can be replaced by a rolling element, which can roll on the sliding guide rail 121, and also facilitates the pushing and pulling of the assembly component.

[0039] Of course, the sliding fit structure is not limited to being arranged between the bottom plate 12 and the bottom of the bracket 30, but can also be arranged between the inner walls of the two side plates 13 and the two side walls of the bracket 30. When the bracket 30 is fixed to the outside of the hot tank 20, when the bracket 30 drives the hot tank 20 to enter the shell 10, the two side walls of the bracket 30 are opposite to the two side walls of the shell 10, and the sliding fit structure arranged between the bracket 30 and the side wall can also limit the hot tank 20 and the bracket 30 in the left-right direction, so as to avoid the left-right shaking of the hot tank 20 and the bracket 30, and facilitate the pushing or pulling of the hot tank 20 and the bracket 30 into or out of the shell 10. Specifically, the sliding fit structure can include guide rails arranged on the inner walls of the two side walls of the shell 10, and sliding blocks or rolling members arranged on the two side walls of the bracket 30 and capable of sliding on the two guide rails, respectively.

[0040] Further, since the hot tank 20 is heavy, in order to facilitate the movement thereof and facilitate the entry and exit of the hot tank 20 into the shell 10, a roller 32 is arranged at the bottom of the bracket 30. As described above, when the sliding fit structure is arranged between the bottom plate 12 and the bottom of the bracket 30, the positions of the roller 32 and the sliding block 31 are spaced apart to avoid interference. When the sliding fit structure is arranged between the two side plates 13 and the two side walls of the bracket 30, the roller 32 can be arranged at the bottom of the bracket 30 at will. The number of the rollers 32 is preferably four, i.e., one at each corner. Of course, in order to better support and move, and ensure the balance after being fixed, the number of the rollers 32 can also be arranged to be more, which is generally an even number and is preferably arranged symmetrically at the bottom of the hot tank 20. As described above, when the rolling member is used instead of the sliding block, the roller is not required here.

[0041] Further, in order to avoid the roller 32 from rolling on the bottom plate 12 in the fixed state, the roller 32 is provided with a brake structure (not shown in the figure). That is, the roller 32 can be used to labor-savingly push the hot tank 20 and the bracket 30 into the shell 10, and when reaching the preset position, the brake structure on the roller 32 is opened, so that the roller 32 is limited to rotate, which can ensure that the hot tank 20 does not move in the shell 10 or make noise due to the rolling of the roller 32 during the carrying process.

[0042] Further, after the hot tank 20 and the bracket 30 are pushed into the shell 10, although the back plate is closed and locked, only the limiting of the front plate 14, the back plate and the two side plates 13, and the connection between the sliding guide rail 121 and the sliding block 31 in the sliding fit structure cannot ensure the stable fixation of the hot tank 20 and the bracket 30, therefore, in the embodiment, a locking structure is further arranged between the shell 10 and the bracket 30, or between the sliding fit structures.

[0043] Specifically, the locking structure can adopt a screw connection structure which is easy to disassemble and assemble, i.e. including a mounting hole arranged on the bottom plate 12 and a connecting piece (not shown in the figure) arranged on the bracket 30, the connecting piece is fixedly connected with the mounting hole through a screw. Of course, the connecting piece can also be arranged on the bottom plate 12, and the mounting hole is arranged on the bracket 30. Similarly, the screw connection structure can also be arranged between the two side plates 13 of the shell 10 and the bracket 30.

[0044] Of course, the locking structure can also adopt a clamping structure which is easy to disassemble and assemble, specifically, the clamping structure includes a clamping hole arranged on the bottom plate 12 and a clamping hook (not shown in the figure) arranged on the bracket 30 which can be flipped. The clamping hook is arranged in a flip structure, i.e. during the pushing and pulling process, the clamping hook is in a folded state to avoid affecting the movement of the bracket 30, and when the bracket 30 is moved into place, the clamping hook is flipped out to face the clamping hole, and is clamped into the clamping hole under the action of an external force. Similarly, the positions of the clamping hook and the clamping hole can be interchanged, and the clamping structure of the clamping hook and the clamping hole can also be arranged between the bracket 30 and the two side walls of the shell 10.

[0045] Referring to Figs. 4 to 6 In the embodiment, the bracket 30 has a relatively simple structure, which includes a plurality of protective frames 33 arranged around the heat tank 20, and a connecting piece 40 connected to the bottom of the front and rear protective frames 33. The connecting piece 40 is a heat insulation piece. The sliding fit structure is arranged between the connecting piece 40 and the bottom plate 12 of the shell 10.

[0046] Specifically, as shown in the figure, each protective frame 33 includes a vertical frame body 331 and an upper connecting block 332 and a lower connecting block 333 respectively located at the top and bottom of the frame body 331, the height of the frame body 331 matches the height of the heat tank 20, and is slightly larger than the height of the heat tank 20, so that when the frame body 331 is arranged on the side of the heat tank 20, the upper connecting block 332 can be overlapped on the top of the heat tank 20, and the lower connecting block 333 can be placed on the bottom of the heat tank 20, and the upper connecting block 332 and the lower connecting block 333 are connected with the heat tank 20 through a fixed connection structure. In the present embodiment, the number of protective frames 33 is preferably four, and the heat tank 20 is protected in all directions by the four protective frames 33, so as to ensure that they can be closely surrounded around the heat tank 20 to form a stable bracket 30. During installation, each protective frame 33 is connected with the heat tank 20 through the upper connecting plate and the lower connecting plate, thereby forming a complete support and protection system, which not only provides necessary support and stability for the heat tank 20, but also can reduce the influence of external factors on the heat tank 20 to a certain extent, such as impact, vibration and temperature change.

[0047] In the embodiment, the connecting piece 40 comprises a bottom support plate 41 and two side support plates on both sides of the bottom support plate 41. The bottom support plate 41 is fixedly connected with the lower connecting plate 333 of the protective frame 33 by bolts, and the inner sides of the two side support plates and the bottom support plate 41 are welded and fixed with the bottom of the heat tank 20. The slider 31 is arranged at the bottom of the bottom support plate 41. Since the bracket 30 is in a frame shape in the embodiment, that is, most of the heat tank 20 is exposed at the bracket 30, the rollers 32 can be arranged at the bottom of the lower connecting block 333 of each protective frame 33 or at the bottom of the heat tank 20. As long as the arrangement position of the rollers 32 does not affect the sliding cooperation between the slider 31 and the sliding guide rail 121, the arrangement position of the rollers 32 can be determined. Similarly, the locking structure can be arranged between the protective frame 33 and the two side plates 13 or between the bottom plate 12 and the bottom support plate 41.

[0048] Of course, as described above, when the sliding cooperation structure is arranged between the two side plates 13 of the shell 10 and the two side walls of the bracket 30, the connecting piece 40 can be arranged between the frame bodies 331 of the front and rear protective frames 33, and the slider 31 is arranged on the connecting piece 40. Similarly, the locking structure is arranged on the connecting piece 40.

[0049] In the embodiment, the fixing piece 50 is arranged at the top of the heat tank 20. The fixing piece 50 is fixedly or detachably arranged on the heat tank 20. Specifically, the fixing piece 50 can be detachably arranged on the heat tank 20 in the form of threaded connection, buckle connection or quick release buckle, and the fixing piece 50 can be fixedly arranged on the heat tank 20 in the form of welding. The fixing piece 50 is in the shape of a Chinese character, and the upper connecting plate of the protective frame 33 is overlapped on the fixing piece 50 and is fixedly connected by bolts. The fixing piece 50 is in the shape of a hollow, which can not only reduce the material usage of the fixing piece 50 itself, but also reduce the contact area with the heat tank 20 and improve the heat insulation effect. In the embodiment, the fixing piece 50 is arranged at each of the four corners of the top of the heat tank 20, so as to provide more uniform support and stability.

[0050] As a preferred embodiment, the fixing piece 50 is also a heat insulation piece. As described above, the connecting piece 40 is also a heat insulation piece, and the heat insulation piece comprises one or more of a non-metal heat insulation piece, a metal heat insulation piece and a composite heat insulation piece.

[0051] The non-metal heat insulation member is made of non-metal heat insulation material, such as rubber pad, rubber sleeve, etc. The non-metal heat insulation member is made of materials including ceramic fiber, rock wool, glass wool, expanded perlite and aluminum silicate fiber, etc. These materials have good high-temperature resistance, low thermal conductivity and excellent heat insulation performance. The metal heat insulation member is made of metal heat insulation material, such as aluminized steel plate and stainless steel heat insulation plate, etc. They have the characteristics of heat insulation, corrosion resistance, high temperature resistance, and also have certain strength and rigidity. The composite heat insulation member is made of composite heat insulation material, such as aerogel heat insulation material, vacuum heat insulation plate and multi-layer composite heat insulation material. These materials can have extremely low thermal conductivity and excellent heat insulation performance after processing.

[0052] Of course, in order to further improve the heat insulation effect between the hot tank 20 and the connecting piece 40 and the fixing piece 50, a coating or protective layer with heat insulation effect can also be coated or covered between the hot tank 20 and the connecting piece 40 and the fixing piece 50 to block or reduce heat transfer and maintain the stability of the internal temperature of the hot tank 20.

[0053] Specifically, the end of the sliding guide rail is provided with a buffer. The buffer can be a rubber block, which can avoid impact of the assembly part or the bracket 30 on the shell 10 during installation, and has good safety and reliability.

[0054] Specifically, the guide rail on both sides of the shell 10 is provided with a dovetail groove, and the sliding block is a dovetail sliding block. In this way, the shell 10 can be reliably attached to a bracket with high rigidity, and the overall stability is good.

[0055] In the embodiment, the hot tank 20 includes a hot tank body and two end covers, and the two end covers are respectively arranged at both ends of the hot tank body to form a sealed structure. The hot tank body serves as the main part of the hot tank 20 and is made of high-strength and corrosion-resistant material to ensure that it can withstand high-temperature and high-pressure working environment. The two end covers are respectively arranged at both ends of the hot tank body and are tightly connected with the hot tank body through a sealing structure (such as flange connection, threaded connection, welding, etc.) to form a sealed structure, so as to ensure that the medium (such as water, steam, etc.) in the hot tank 20 will not leak to the external environment, and also prevent external impurities from entering the hot tank 20, thereby ensuring normal operation of the hot tank 20 and purity of the medium.

[0056] As a preferred embodiment, a heating resistance tube is arranged in the hot tank 20. According to the above technical solution, the heating resistance tube in this embodiment is a kind of heating element that generates heat by passing current through resistance material. In the working process, the current passes through the heating resistance tube, causing the resistance material inside to heat up, and then transferring heat to the surrounding medium. Since the heating resistance tube is in direct contact with the medium, it can efficiently transfer heat, causing the medium in the square tank to quickly heat up to the required temperature. By adjusting the power and working time of the heating resistance tube, the heating speed and temperature range of the medium in the hot tank 20 can be flexibly controlled to meet the needs of different application scenarios.

[0057] As a preferred embodiment, the outer side of the hot tank body 21 is sleeved with a heat preservation sleeve 60, which is arranged in the bracket 30. The heat preservation sleeve 60 is through from top to bottom and does not affect the sliding fit structure between the bracket 30 and the shell 10. The main function of the heat preservation sleeve 60 is to reduce the heat loss of the hot tank 20 (especially the hot tank body 21), improve the thermal efficiency, and ensure the stable operation of the medium within the set temperature range. The heat preservation sleeve 60 is tightly sleeved on the outer side of the hot tank body 21 to form a continuous heat preservation layer, which can be made of high thermal resistance materials such as rock wool, aluminum silicate fiber, polyurethane foam, etc. These materials have excellent heat insulation performance and can effectively block the transfer of heat. In the bracket 30, the heat preservation sleeve 60 not only plays a heat preservation and insulation role, but also provides certain protection and support for the hot tank body 21. The heat preservation sleeve 60 can tightly fit the outer wall of the hot tank body 21 to reduce heat loss through air gaps. At the same time, the heat preservation sleeve 60 has certain strength and rigidity, which can ensure that it can withstand the weight and pressure from the hot tank body 21 and its internal medium, preventing safety hazards caused by deformation or damage. In the working process, when the hot tank 20 heats the medium through the heating resistance tube, the heat preservation sleeve 60 can reduce heat loss, so that the medium can quickly reach the required temperature and remain stable. This not only improves the heating efficiency of the drinking water equipment, but also reduces energy consumption and prolongs the service life of the equipment. The structure is compact and practical.

[0058] The above disclosure is only the preferred embodiment of the present application, and of course cannot limit the scope of the rights of the present application, so the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
