Description

Technical Field

[0001] The invention relates to the technical field of electric water heaters, and in particular to an electric water heater that can be installed in an assembled toilet. Background Art

[0002] An electric water heater is a water heater that uses electricity as energy for heating. It is one of the three major water heaters along with gas water heaters and solar water heaters. Electric water heaters are widely used because of their easy installation and relatively constant water temperature.

[0003] The structure of the electric water heater mainly includes a shell, an inner tank, and a bracket. The existing electric water heaters are equipped with brackets for installation on the wall, and the brackets are generally locked on the wall by bolts, such as the electric water heater in the utility model patent with publication number CN 201909449U.

[0004] However, the above-mentioned bracket of the electric water heater is difficult to be fixedly installed on the wall panel of the assembled toilet. Referring to the assembled toilet wall panel system and assembled toilet disclosed in the patent with publication number CN 211447935 U, the reasons why the existing bracket is not suitable for installation on the wall panel are as follows: 1. The wall panel of the assembled toilet is waterproofed. If the bracket is fixed to the wall panel by bolts, it is necessary to drill holes in the wall panel. For wooden wall panels, water is easily infiltrated at the drilled holes and the wall panel is damaged; 2. Many wall panels are composed of a rigid outer frame and an intermediate filling plate. If a hole is drilled in the rigid outer frame to install the water heater, it is easy to be restricted by the ceiling and insufficient space, and the intermediate filling plate cannot bear the weight of the water heater.

[0029] Reference Figures 1 to 9 The present invention proposes an electric water heater that can be installed in an assembled toilet, comprising an upper wall frame and a hanging frame 2 fixed on the water heater body 1, the hanging frame 2 comprising an upper support leg 21 and a lower support leg 22, the upper wall frame comprising a rear frame 31, a front frame 32, and a top frame 33 connected between the upper end of the front frame 32 and the upper end of the rear frame 31, a receiving space for inserting a wall panel 4 is formed between the rear frame 31, the front frame 32 and the top frame 33, a locking mechanism capable of locking the wall panel 4 inserted into the receiving space is provided on the front frame 32, a supporting cross bar 34 and a movable sleeve rod 35 that can move up and down are provided on the front frame 32, a first plug hole 341 for inserting the lower support leg 22 is provided on the supporting cross bar 34, a second plug hole 351 located above the supporting cross bar 34 is provided on the movable sleeve rod 35, and when the lower support leg 22 is inserted into the first plug hole 341, the movable sleeve rod 35 can move downward to allow the upper support leg 21 to be inserted into the second plug hole 351.

[0030] Example 1

[0031] Figures 1 to 6The embodiment 1 of the present invention is shown. In this embodiment, the main bodies of the front frame 32, the rear frame 31, and the top frame 33 are made of alloy steel, which can be processed and formed by bending, welding, etc. The locking mechanism includes a first screw 51 fixed to the rear surface of the front frame 32, and a screw block 52 screwed to the first screw 51. The first screw 51 can be fixed to the front frame 32 by welding, screwing, etc. The water heater body 1 includes an outer shell 11, an inner tank 12 located in the outer shell 11, and an insulation layer 13 arranged between the outer shell 11 and the inner tank 12. The insulation layer 13 can be made of materials such as foamed polyurethane.

[0032] Specifically, the hanger 2 includes two hanging rods, the rear frame 31 is U-shaped, and the two U-shaped ends of the rear frame 31 are integrally connected to the rear ends of the two hanging rods. The front frame 32 also includes two vertical rods, and the upper ends of the two vertical rods are respectively integrally connected to the front ends of the two hanging rods. The support cross bar 34 is fixed between the lower ends of the two vertical rods by welding, screwing, etc. The hanging rod is installed on the shell and fixedly connected to the inner tank by bolts. The upper end of the hanging rod is an upper support leg 21, and the lower end is a lower support leg 22. The two hanging rods are arranged on the water heater body 1 one left and one right. Therefore, the number of the upper support legs 21 is two and the two upper support legs 21 are arranged one left and one right, and the number of the lower support legs 22 is two and the two lower support legs 22 are arranged one left and one right. The number of the first plug holes 341 is two and corresponds to the two lower support legs 22 one by one, and the number of the second plug holes 351 is two and corresponds to the two upper support legs 21 one by one. The number of the first screw rod 51 and the screw block 52 is two.

[0033] In this embodiment, collars are fixed to both ends of the movable sleeve rod 35 , and the two collars are respectively sleeved on two vertical rods of the front frame 32 , so that the movable sleeve rod 35 can move up and down on the front frame 32 .

[0034] In this embodiment, the method of installing the water heater body 1 on the wall panel 4 of the assembled toilet is:

[0035] S1. Hang the upper wall frame on the wall panel 4, so that the rear frame 31 is located at the rear side of the wall panel 4, the front frame 32 is located at the front side of the wall panel 4, and the top frame 33 is supported on the frame at the top of the wall panel 4;

[0036] S2, then rotate the screw block 52 to press the front side of the wall panel 4, and the installation of the upper wall frame is completed;

[0037] S3. Lift the water heater body 1, insert the two lower legs 22 of the bracket 2 into the two first plug holes 341 on the front frame 32 one by one, and align the two upper legs 21 of the bracket 2 with the two second plug holes 351 on the movable sleeve rod 35, then move the movable sleeve rod 35 downward to insert the two upper legs 21 into the corresponding second plug holes 351 respectively, and the installation of the water heater body 1 is completed.

[0038] In some cases, due to the influence of the dimensional accuracy, installation accuracy, dimensional accuracy of the upper wall frame, flatness of the top of the wall panel 4, etc. of the bracket 2, the height difference between the left and right ends of the water heater body 1 after being installed on the upper wall frame will be large. At this time, it is necessary to adjust the upper wall frame or the bracket 2 so that the left and right ends of the water heater body 1 are basically at the same level.

[0039] In order to solve the above problem, the following design is made in this embodiment: the top frame 33 includes two top rods 331 arranged on the left and the right, a support block 61 is arranged under the top rod 331, a transmission structure is arranged between the support block 61 and the top rod 331, and a manual driving mechanism capable of driving the support block 61 to move forward and backward is arranged on the front frame 32. When the support block 61 moves backward, the corresponding top rod 331 is driven to move upward to adjust the height difference between the two top rods 331. Specifically, a thrust member 301 is fixed to the lower surface of the top rod 331, and the transmission structure includes a thrust inclined surface 302 arranged on the thrust member 301, and a push inclined surface 611 arranged on the support block 61 and matched with the thrust inclined surface 302, and the angle between the push inclined surface 611 and the horizontal plane is generally 15-40 degrees, such as 30 degrees and 25 degrees. A nut 62 is fixed on the front frame 32, and the manual drive mechanism includes a second screw rod 64 meshing with the nut 62, a hand wheel 63 is provided at the front end of the second screw rod 64, and the rear end of the second screw rod 64 abuts against the support block 61. Furthermore, a guide groove 303 is provided on the bearing and thrust inclined surface 302, and a protrusion 612 that slidably cooperates with the guide groove 303 is provided on the top thrust inclined surface 611.

[0040] Reference Figure 4 and Figure 5 By turning the hand wheel 63, the support block 61 can be pushed backward, and the corresponding top rod 331 can be lifted to a certain height, which is generally several millimeters to several tens of millimeters. By lifting the corresponding top rod 331, the height difference between the two top rods 331 can be adjusted, and the height difference between the left and right ends of the support cross bar 34 can be adjusted, and finally the left and right ends of the water heater body 1 are at approximately the same height. The use of such a method to adjust the posture of the water heater body 1 after installation has the advantages of simple structure, low cost, and convenient adjustment, and there is no need to set the force-bearing part on the upper wall frame to a retractable structure, so as to ensure that the strength of the upper wall frame can meet the requirements.

[0041] Example 2

[0042] Figure 7 Embodiment 2 of the present invention is shown. This embodiment has a similar structure to Embodiment 1, and the difference lies in the specific shape of the support block 61 and the specific form of the transmission structure between the support block 61 and the push rod 331.

[0043] In this embodiment, the top of the support block 61 is in contact with the push rod 331, and the transmission structure includes two connecting rods 66. The upper end of the connecting rod 66 is hinged to the push rod 331, and the lower end of the connecting rod 66 is hinged to the support block 61. The four hinge points of the two connecting rods 66 constitute the four vertices of the same parallelogram. A nut 62 is fixed on the front frame 32. The manual drive mechanism includes a second screw rod 64 meshing with the nut 62. A hand wheel 63 is provided at the front end of the second screw rod 64. When the hand wheel 63 is turned, the support block 61 is pushed backward by the second screw rod 64. In the initial state, the angle between the two connecting rods 66 and the horizontal plane is generally 50-65 degrees, such as 50 degrees, 60 degrees, etc. After the support block 61 moves backward a certain distance, the angle between the two connecting rods 66 and the horizontal plane becomes larger, such as increasing from 50 degrees to 70 degrees, and the corresponding push rod 331 is lifted a certain distance.

[0044] Further, the top rod 331 is provided with a limit block 305 capable of abutting against the connecting rod 66 to limit the maximum rotation angle of the connecting rod 66. Preferably, the position of the limit block 305 is set in the following manner: when the two connecting rods 66 abut against the corresponding limit block 305, the angle between the two connecting rods 66 and the horizontal plane is 91-100 degrees, such as 95 degrees.

[0045] Compared with the first embodiment, the advantage of the present embodiment is that when the corresponding top rod 331 is lifted to the same height, the support block 61 in the present embodiment needs to move backwards a smaller distance. Figure 4 and Figure 7 The distance between the rear end of the support block 61 in this embodiment and the rear surface of the wall panel 4 can also be designed to be smaller, so that the contact area between the support block 61 and the top frame of the wall panel 4 is larger and the stability is better.

[0046] Example 3

[0047] Figures 8 to 9The third embodiment of the present invention is shown. This embodiment has a similar structure to the first embodiment, except that in this embodiment, a through hole 211 is provided on the upper support leg 21. When the water heater is installed on a common wall, the through hole 211 is used to install a bolt to fix the bracket 2 on the wall. The movable sleeve rod 35 is provided with an elastic clamp 7. The elastic clamp 7 is provided with a clamping portion 701 that can be clamped into the through hole 211 when the upper support leg 21 is inserted into the second insertion hole 351 to prevent the movable sleeve rod 35 from being separated from the upper support leg 21. The elastic clamp 7 is a spring sheet, and the elastic clamp 7 includes a rear spring sheet 71, a front spring sheet 72, and an arc-shaped spring sheet 73 connected between the lower end of the front spring sheet 72 and the lower end of the rear spring sheet 71. The rear spring sheet 71 is fixed to the movable sleeve rod 35, and the front spring sheet 72 is fixed to the rear inner wall of the second socket 351. The clamping portion 701 is a convex portion provided on the front spring sheet 72 and protruding forward. The lower surface of the convex portion is an inclined surface inclined toward the front, and the upper end of the front spring sheet 72 extends out from the upper end of the second socket 351.

[0048] Compared with the first embodiment, the advantages of the present embodiment are: after the upper leg 21 of the rack 2 is inserted into the second insertion hole 351, the locking portion 701 on the elastic clamp 7 can be locked into the through hole 211 on the upper leg 21, locking the rack 2 and the movable sleeve rod 35, and preventing the movable sleeve rod 35 from being separated from the rack 2 when the user accidentally touches the movable sleeve rod 35. When the water heater body 1 needs to be removed, the upper end of the front spring sheet 72 can be pushed backward to elastically deform the elastic clamp 7, so that the locking portion 701 on the front spring sheet 72 can be pulled out of the through hole 211, and then the movable sleeve rod 35 can be pushed upward to make the upper leg 21 disengage from the second insertion hole 351, and finally the water heater body 1 and the rack 2 are lifted upward together, so that the water heater body 1 can be removed, which is convenient and quick.

[0049] In addition, the reason why the front spring piece 72 of the elastic clamp 7 is fixed on the rear inner wall of the second hole 351 is that when the water heater body 1 is installed on the upper wall frame, under the action of the gravity of the water heater body 1, the upper support leg 21 tends to flip clockwise. Therefore, it is mainly the front inner wall of the second hole 351 on the movable sleeve rod 35 that bears the pressure of the upper support leg 21. The elastic clamp 7 adopts such a design, which can not only lock the movable sleeve rod 35 and the upper support leg 21, but also will not affect the supporting strength of the movable sleeve rod 35 on the upper support leg 21.

[0050] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
