Description

Technical Field

[0001] The present application belongs to the technical field of hot water equipment, and specifically relates to an inner tank fixing structure and a double inner tank hot water equipment. Background Art

[0002] The double-tank water heater uses two interconnected tanks for heating, which can effectively increase the heating rate. The two tanks of the double-tank water heater generally need to be arranged in parallel to make the water heater structure more compact and reduce the volume.

[0003] At present, when fixing the two inner tanks of a double-tank water heater, it is generally necessary to clamp the steel hoop on the outside of the two inner tanks, that is, each steel hoop must be tightened on the outside of the two inner tanks at the same time to limit the relative position of the two inner tanks. The steel hoop is also connected to the bracket to support the inner tank through the bracket. In the process of fixing the two inner tanks, the operator needs to use a lot of strength to complete it, and requires the assistance of multiple people, which is time-consuming and laborious. At the same time, when connecting the steel hoop and the bracket, it is mainly positioned manually, which easily causes the bracket to deflect, affecting the installation of the water heater. Utility Model Content

[0004] The present application provides an inner tank fixing structure and a double-tank hot water device to solve the problem that the existing double-tank hot water device is time-consuming and labor-intensive to fix the inner tank, and easily causes the hanging rack to deflect, thus affecting the installation of the hot water device.

[0005] The technical solutions adopted in this application are as follows:

[0006] A first aspect of an embodiment of the present application provides an inner tank fixing structure for fixing the inner tank of a water heater, wherein the water heater comprises two inner tanks, and the inner tank fixing structure comprises a first hanger, a second hanger and at least one connecting member, wherein both ends of the connecting member are detachably connected to the first hanger and the second hanger respectively to limit the relative position of the first hanger and the second hanger, wherein the first hanger is used to connect to one of the inner tanks, and the second hanger is used to connect to the other of the inner tanks to limit the relative position of the two inner tanks.

[0007] In some possible designs, a flange and a heating tube are provided on the top of the inner container;

[0008] The first bracket and the second bracket each include a bracket body, an upper connecting portion and a lower connecting portion, wherein the upper connecting portion and the lower connecting portion are respectively connected to two ends of the bracket body, the upper connecting portion is used to be installed between the flange and the heating tube, and the lower connecting portion is used to be connected to the lower end of the inner tank.

[0009] In some possible designs, the upper connecting part is a first positioning ring, and at least one of a first positioning groove or a positioning hole is provided on the first positioning ring, and the first positioning groove or the positioning hole corresponds to the position of the hole on the flange plate for connecting the heating tube, so that the bolts used to connect the flange plate and the heating tube can pass through the first positioning groove or the positioning hole.

[0010] In some possible designs, a base is provided at the bottom of the inner container, and the lower connecting portion is a second positioning ring, and the second positioning ring is used to be sleeved on the base.

[0011] In some possible designs, the lower connecting portion includes an arc-shaped positioning hoop and two connecting ears, and the two connecting ears are respectively located at both ends of the positioning hoop. The two connecting ears are used to connect the two ends of the positioning hoop when the positioning hoop is sleeved on the outside of the inner liner, so that the positioning hoop clamps the inner liner.

[0012] In some possible designs, two connecting members are arranged side by side, and the extending direction of the connecting member is perpendicular to the extending direction of the bracket body.

[0013] In some possible designs, a positioning protrusion is provided on the bracket body, and second positioning grooves cooperating with the positioning protrusion are provided at both ends of the connecting member, and the positioning protrusion and the second positioning groove are detachably connected.

[0014] In some possible designs, an insulating spacer is further included, and the insulating spacer is located on a side of the connecting member away from the bracket body.

[0015] In some possible designs, the connector is provided with snap-fitting portions on both opposite sides, and the insulating spacer is provided with a hook that cooperates with the snap-fitting portion, so that the insulating spacer is fixed on the connector when the hook is engaged with the snap-fitting portion.

[0016] A second aspect of an embodiment of the present application provides a double-tank water heating device, comprising two tanks, and also comprising a tank fixing structure as described in any one of the first aspects, wherein one of the two tanks is connected to a first bracket of the tank fixing structure, and the other is connected to a second bracket.

[0017] In the inner tank fixing structure and double-tank hot water equipment provided by the present application, the inner tank fixing structure fixes an inner tank respectively through a first hanger and a second hanger, and connects the first hanger and the second hanger through at least one connecting piece, so that the first hanger and the second hanger cannot move relative to each other, thereby preventing the two inner tanks from moving relative to each other, thereby achieving the fixation of the inner tank. Such a fixing method does not require the use of steel hoops to clamp the outer sides of the two inner tanks at the same time, but directly connects the inner tanks to the first hanger and the second hanger separately, making the connection between the fixing structure and the inner tank more convenient, reducing the force required by the operator to fix the inner tank, and at the same time, the number of positioning points that need to be manually found during fixing is also reduced, which can greatly improve the efficiency of fixing the inner tank. In addition, connecting the first hanger and the second hanger through a connecting piece can also prevent the first hanger and the second hanger from being skewed, thereby improving the fixing effect of the inner tank.

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

[0038] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here, for example.

[0040] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0041] At present, when fixing the two inner tanks of a double-tank hot water device, it is generally necessary to clamp the steel hoop on the outside of the two inner tanks, that is, each steel hoop must be tightened on the outside of the two inner tanks at the same time to limit the relative position of the two inner tanks. The steel hoop is also connected to the bracket to support the inner tank through the bracket.

[0042] This fixing method has at least the following problems:

[0043] 1. In the process of fixing the two inner tanks, the operator needs to use a lot of strength to complete it, and needs the assistance of multiple people, which is time-consuming and laborious;

[0044] 2. When connecting the steel hoop and the bracket, the positioning is mainly done by manually finding the positioning points, which can easily cause the bracket to deflect and affect the installation of the hot water equipment;

[0045] 3. After the inner liner is fixed, it needs to be manually checked by hammering, which will further extend the time required to fix the inner liner.

[0046] In order to avoid the above-mentioned problems, the present application provides an inner tank fixing structure and a double inner tank hot water device, which replaces the traditional manual positioning point finding through the structural design of the inner tank fixing structure, and does not require manual force to clamp the tank, thereby greatly reducing the difficulty of fixing the inner tank and improving the fixing efficiency of the inner tank. At the same time, it can also ensure that the first hanging bracket and the second hanging bracket are not skewed during installation, thereby improving the fixing effect of the inner tank.

[0047] The embodiments of the present application are described below with reference to the accompanying drawings.

[0048] See also Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides an inner tank 100 fixing structure for fixing two inner tanks 100 of a double inner tank 100 water heater, which includes a first hanger 200, a second hanger 300 and at least one connector 400.

[0049] The two ends of the connecting piece 400 are detachably connected to the first hanger 200 and the second hanger 300 respectively to limit the relative position of the first hanger 200 and the second hanger 300, that is, the first hanger 200 and the second hanger 300 are pre-arranged with a structure for connecting with the connecting piece 400, and the connecting piece 400 can be directly installed at the corresponding positions of the first hanger 200 and the second hanger 300 without manually finding the positioning points. While improving the processing efficiency, it can also effectively prevent the first hanger 200 and the second hanger 300 from being skewed.

[0050] It is understandable that the connecting member 400 can be connected to the first hanger 200 and the second hanger 300 by a common connection method, as long as it is ensured that the connecting member 400 and the first hanger and the second hanger 300 do not move relative to each other during operation.

[0051] The first bracket 200 is used to connect to one inner liner 100, and the second bracket 300 is used to connect to another inner liner 100. The first bracket 200, the second bracket 300 and the inner liner 100 can be connected by any common method, such as welding, tightening on the outside of the inner liner 100, connecting to the inner liner 100 by fasteners such as bolts, etc., as long as it is ensured that the inner liner 100 and the first bracket 200 and the second bracket 300 do not move relative to each other.

[0052] Specifically, when fixing the inner liner 100, first connect the first hanger 200 to one inner liner 100, connect the second hanger 300 to the other inner liner 100, and then connect the first hanger 200 and the second hanger 300 through the connecting piece 400. No measurement and positioning are required, which greatly improves the convenience of fixing the inner liner 100, thereby effectively improving the efficiency of fixing the inner liner 100. At the same time, when fixing the inner liner 100, the first hanger 200 and the second hanger 300 are each connected to an inner liner 100, which can effectively reduce the difficulty of operation and reduce the workload of the operator.

[0053] During actual use, a flange 120 is provided at one end of the inner tank 100 (for ease of understanding, this application regards this end as the top of the inner tank 100, and the other end opposite thereto is correspondingly regarded as the bottom of the inner tank 100), and the heating tube 110 is fixed to the inner tank 100 through the flange 120, so that the heating tube 110 can extend to the interior of the inner tank 100 to heat the water in the inner tank 100, and the heating tube 110 and the flange 120 are connected by bolts, that is, holes are correspondingly provided at the connecting parts of the flange 120 and the heating tube 110. When installing the heating tube 110, the two can be fixed directly by passing the bolts through the holes on the flange 120 and the heating tube 110.

[0054] In order to maximize the adaptability to the structure of the liner 100 and improve the convenience and fixation effect of the liner 100, in some possible implementations, please refer to Figure 1 and Figure 2 As shown, the first bracket 200 and the second bracket 300 can both include a bracket body 210, an upper connecting portion 220 and a lower connecting portion. The upper connecting portion 220 and the lower connecting portion are respectively connected to the two ends of the bracket body 210. The upper connecting portion 220 is used to be installed between the flange 120 and the heating tube 110 to fix the inner liner 100 from the upper end of the inner liner 100, and the lower connecting portion is used to be connected to the lower end of the inner liner 100 to fix the inner liner 100 from the lower end of the inner liner 100, thereby fixing the inner liner 100 from both the upper and lower ends of the inner liner 100 to improve the fixing effect.

[0055] The bracket body 210 can be of any shape as long as both ends can extend to corresponding positions to connect with the upper connecting part 220 and the lower connecting part to effectively fix the inner liner 100.

[0056] It is understandable that in order to improve the strength of the rack, the upper connecting portion 220, the lower connecting portion and the rack body 210 can be integrally formed. Of course, the upper connecting portion 220, the lower connecting portion and the rack body 210 can also be separately provided and connected in a common connection manner, which is not limited in this embodiment.

[0057] As an implementation of the upper connecting portion 220, see Figure 2 ,, Figure 3 , Figure 4 , Figure 7 and Fig. 9As shown, the upper connecting portion 220 is a first positioning ring 221, and the first positioning ring 221 is connected to one end of the bracket body 210. The first positioning ring 221 is provided with at least one of a first positioning groove 222 or a positioning hole 223, and the first positioning groove 222 or the positioning hole 223 corresponds to the position of the hole on the flange 120 for connecting the heating pipe 110, so that the bolt used to connect the flange 120 and the heating pipe 110 can pass through the first positioning groove 222 or the positioning hole 223, wherein the first The number of the positioning groove 222 and the positioning hole 223 can be one, or can correspond to the number and position of the holes on the flange 120, so that when the heating tube 110 is fixed on the flange 120, the upper connecting part 220 and the inner liner 100 are directly fixed, which effectively reduces the fixing steps of the inner liner 100 and the positioning points required for fixing the inner liner 100, simplifies the fixing operation of the inner liner 100, greatly improves the efficiency of fixing the inner liner 100, and reduces the difficulty of fixing the inner liner 100.

[0058] Specifically, when fixing the inner tank 100, the first positioning ring 221 is placed above the flange 120, and the first positioning groove 222 or the positioning hole 223 on the first positioning ring 221 corresponds to the holes on the flange 120 in sequence, and then the heating tube 110 is placed above the first positioning ring 221, and the hole on the first positioning ring 221 corresponds to the hole on the heating tube 110 for connecting with the flange 120, and then the bolts are passed through the holes on the flange 120, the first positioning groove 222 or the positioning hole 223, and the holes on the heating tube 110 to fix the heating tube 110, the upper connecting part 220 and the flange 120 together.

[0059] Of course, the upper connecting portion 220 can also be in other shapes, as long as it can be located between the flange 120 and the heating tube 110, and the upper connecting portion 220 can be connected to the flange 120 by a common connection method, or it can be set to be annular and directly stuck between the flange 120 and the heating tube 110, and the upper connecting portion 220 is pressed by the heating tube 110 so that the upper connecting portion 220 will not be separated from the inner tank 100. It can be understood that the structure of the upper connecting portion 220 is only for illustration, not for limitation.

[0060] It is understandable that the inner liner 100 is placed horizontally during use. As long as the upper connecting part 220 can bear the weight of the inner liner 100, and the lower connecting part assists in limiting the position of the upper connecting part 220, even if the upper connecting part 220 is directly pressed between the flange 120 and the heating tube 110, it will not affect the heating tube 110.

[0061] To protect the heating tube 110, see Figure 4As shown, a rubber pad 140 is generally added between the heating pipe 110 and the flange 120 to protect the contact surface between the heating pipe 110 and the flange 120, prevent the heating pipe 110 from excessive vibration, and reduce the running noise of the hot water device. When adding the rubber pad 140, the rubber pad 140 can be arranged above the upper connecting portion 220 so that it is located between the upper connecting portion 220 and the heating pipe 110.

[0062] As a first embodiment of the lower connection part, see Figure 2 , Figure 3 , Figure 4 As shown, a base 130 is provided at the bottom of the inner liner 100, and the lower connecting part is a second positioning ring 230, and the second positioning ring 230 is connected to the end of the bracket body 210 away from the first positioning ring 221, and the second positioning ring 230 is used to be sleeved on the base 130, that is, the hole in the middle of the second positioning ring 230 is adapted to the outer diameter of the base 130.

[0063] When fixing the inner tank 100, the first positioning ring 221 is fixed between the flange 120 and the heating tube 110 and cannot shift relative to the inner tank 100, and the second positioning ring 230 is fixed at the other end of the bracket body 210. The bracket body 210, the first positioning ring 221, and the second positioning ring 230 are all rigid structures, so the second positioning ring 230 will not move relative to the inner tank 100.

[0064] Such a setting makes it possible to fix the inner liner 100 without the need for manual positioning, and when the first positioning ring 221 and the second positioning ring 230 are connected to the inner liner 100, there is no need for welding, clamping and other operations, which can not only effectively improve the processing efficiency, but also greatly reduce the operating difficulty. In addition, after the inner liner 100 is fixed, there is no need for manual knocking and verification, which further reduces the operating burden of the operator and improves the processing efficiency.

[0065] In addition, in order to facilitate the connection between the first positioning ring 221 and the second positioning ring 230 and the inner liner 100 and enhance the supporting effect on the inner liner 100, the bracket body 210 can be a steel plate, which includes a rectangular section and arc sections located at both ends of the rectangular section. The rectangular section can be fitted with the side wall of the inner liner 100, and one of the two arc sections is used to extend and transition to the top of the flange 120, and the other is used to extend and transition to the bottom of the inner liner 100.

[0066] As another embodiment of the lower connecting portion, see Figure 5 , Figure 6 , Figure 8 , Fig.11As shown, the lower connecting portion includes an arc-shaped positioning hoop 240 and two connecting ears 241. The two connecting ears 241 are respectively located at the two ends of the positioning hoop 240. The two connecting ears 241 are used to connect the two ends of the positioning hoop 240 when the positioning hoop 240 is sleeved on the outside of the inner liner 100, so that the positioning hoop 240 clamps the inner liner 100 to fix the inner liner 100. Of course, in order to improve the fixing effect of the inner liner 100, the positioning hoop 240 is preferably clamped at the lower end of the inner liner 100, that is, the upper connecting portion 220 and the lower connecting portion are arranged on both sides of the center line of the inner liner 100, so that the hanger fixes the inner liner 100 from the top and the bottom of the inner liner 100.

[0067] It is understandable that the connecting ears 241 can be detachably connected in a conventional manner, such as by connecting or snapping with fasteners such as bolts, etc., as long as the two connecting ears 241 do not automatically separate after the inner liner 100 is fixed, and this embodiment does not limit it.

[0068] In addition, the lower connecting portion may also be arranged in other common ways, as long as the inner liner 100 can be effectively fixed, and this embodiment does not limit it.

[0069] In some possible embodiments, two connecting members 400 are arranged side by side, and the extension direction of the connecting members 400 is perpendicular to the extension direction of the bracket body 210. Of course, the two connecting members 400 are preferably located on both sides of the center line of the inner liner 100, that is, distributed at the upper and lower ends of the inner liner 100, so as to better limit the relative position of the first bracket 200 and the second bracket 300 to prevent the two from shifting during use.

[0070] It is understandable that the number of connecting parts 400 can also be set to other values, such as one, three, etc., which can be selected according to actual conditions. As long as the positions of the first bracket 200 and the second bracket 300 can be effectively restricted, this embodiment does not limit it here.

[0071] For further information, see Figure 6 , Fig.10 , Fig.12 , Fig.13 , Fig.14 As shown, a positioning protrusion 250 is provided on the bracket body 210, and second positioning grooves 410 cooperating with the positioning protrusion 250 are provided at both ends of the connecting member 400, and the positioning protrusion 250 and the second positioning groove 410 are detachably connected.

[0072] Specifically, when connecting the bracket body 210 and the connecting piece 400, the second positioning groove 410 on the connecting piece 400 is engaged with the outer side of the positioning protrusion 250, which can effectively position the installation point of the connecting piece 400 and the bracket body 210 without manually finding the positioning point, further avoiding the first bracket 200 and the second bracket 300 from being skewed during the connection process with the connecting piece 400.

[0073] Exemplarily, holes can be opened in the middle of the positioning protrusion 250 and the second positioning groove 410, so that bolts pass through the holes on both to lock the second positioning groove 410 and the positioning protrusion 250, so that the connecting member 400 and the bracket body 210 are stably connected.

[0074] It is understandable that the positioning protrusion 250 and the second positioning groove 410 may be detachably connected by other common fastening methods, as long as the two can be stably connected, and this embodiment does not limit this.

[0075] As a possible implementation of the positioning protrusion 250, the positioning protrusion 250 can be a steel plate welded to the side of the bracket body 210 away from the inner liner 100, that is, the positioning protrusion 250 can be a U-shaped structure, and the two ends can be perpendicular to the bracket body 210 or at a certain angle. At the same time, the two ends are welded to the bracket body 210 to form a protrusion on the side of the bracket body 210 away from the inner liner 100. Of course, it can be understood that the positioning protrusion 250 can also be other structures, as long as it has a part protruding from the bracket body 210 and can be engaged with the connecting piece 400 to position the connecting piece 400, this embodiment does not limit it here.

[0076] It is understandable that the positioning protrusion 250 can also be connected to the bracket body 210 in other ways, or the positioning protrusion 250 can be directly integrally formed with the bracket body 210, that is, when the bracket body 210 is processed, a protrusion is directly set at the corresponding position of the bracket body 210. As long as the connection between the connecting member 400 and the bracket body 210 can be positioned by the positioning protrusion 250, this embodiment does not limit the setting method of the positioning protrusion 250.

[0077] In addition, the second positioning groove 410 of the connecting member 400 can be set at the end of the connecting member 400, and the second positioning groove 410 can be engaged with a part of the positioning protrusion 250 or the entire positioning protrusion 250. As long as the connection position between the connecting member 400 and the bracket body 210 can be unique and determined through the second positioning groove 410 and the positioning protrusion 250, this embodiment does not limit it here.

[0078] Of course, since the positioning protrusion 250 is fixedly connected to the bracket body 210, the second positioning groove 410 may not be in direct contact with the bracket body 210, but may be in direct contact with the positioning protrusion 250 to limit the position of the bracket body 210. Of course, the second positioning groove 410 close to the side of the inner liner 100 may also abut against the surface of the bracket body 210 to increase the contact surface, which is not limited in this embodiment.

[0079] For some possible implementations, see Figure 6 As shown, the fixing structure of the liner 100 also includes an insulating spacer 500, which is located on the side of the connector 400 away from the bracket body 210, and the insulating spacer 500 protrudes from the side of the connector 400 away from the bracket body 210, mainly playing an insulating protection role.

[0080] In order to ensure that the insulating spacer 500 protrudes from the side of the connector 400 away from the rack body 210 , the insulating spacer 500 may be located at the side of the second positioning groove 410 away from the rack body 210 .

[0081] For further information, see Figure 6 , Fig.15 and Fig.16 As shown, the insulating spacer 500 can be detachably connected to the connector 400 for maintenance.

[0082] Exemplarily, hooks 510 can be provided on opposite sides of the insulating spacer 500, the hooks 510 are located on the side of the insulating spacer 500 facing the connector 400, and a snap-fitting portion 420 cooperating with the hooks 510 is provided on the edge of the second positioning groove 410. After the connector 400 is connected to the bracket body 210, the hooks 510 of the insulating spacer 500 are directly snap-fitted into the snap-fitting portion 420 to connect the insulating spacer 500 to the connector 400.

[0083] When the second positioning groove 410 is connected to the positioning protrusion 250 by bolts, a corresponding hole can be opened on the insulating spacer 500, and the positioning protrusion 250, the second positioning groove 410 and the insulating spacer 500 can be fixed synchronously by one bolt, thereby simplifying the installation steps.

[0084] It is understandable that the insulating spacer 500 and the connector 400 may also be connected in other ways, as long as it is ensured that the two will not be separated from each other during the use of the liner 100, and this embodiment does not limit this.

[0085] The embodiment of the present application also provides a double-tank 100 water heating device, which includes two tanks 100 and the tank 100 fixing structure in the above embodiment.
