Description

Technical Field

[0001] This utility model belongs to the field of electric water heater technology, and in particular relates to an electric water heater that is installed to prevent tipping. Background Technology

[0002] Electric water heaters must be installed correctly according to the instruction manual to function properly. However, in practice, some users, for convenience and to save money, do not hire professional after-sales personnel for installation. Due to limited space or failure to follow the manual's instructions, incorrect installation often occurs. For example, a water heater that should be wall-mounted is often installed horizontally for convenience. Incorrect installation prevents the water heater from filling completely, leaving a large amount of air inside the tank and exposing the heating element. This can lead to problems such as poor water flow, abnormal temperature control, and dry burning of the heating element, rendering the water heater unusable and posing significant safety hazards. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing an electric water heater that prevents tipping during installation, thereby solving the technical problem that electric water heaters are easily installed in the wrong direction, causing them to malfunction.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] An electric water heater designed to prevent tipping, comprising a water heater body, the water heater further comprising:

[0006] The hook includes an outer plate, an inner plate, a connecting block, and gears. The outer plate is fixedly connected to the surface of the electric water heater body. Several gears are rotatably installed between the outer plate and the inner plate. The outer plate and the inner plate are fixedly connected by the connecting block.

[0007] The hanging plate and the hook are designed separately. Several mounting seats are fixed on one side of the hanging plate. The mounting seats have mounting grooves, and the hooks are inserted into the mounting grooves.

[0008] The skateboard has a movable cavity inside the mounting base. The skateboard is slidably installed in the movable cavity. A fixing plate is fixed to the bottom of the movable cavity. The fixing plate is fitted inside the skateboard. An elastic element connects the fixing plate and the skateboard.

[0009] The mounting base has several through holes that connect the mounting groove to the movable cavity. The through holes are elastically rotatably connected to the through holes. The sliding plate has several notches and slots on the side near the ratchet. The ratchet has a protrusion. One notch and one slot are a pair corresponding to one protrusion on the ratchet. The notch corresponding to the ratchet is located above the slot corresponding to the ratchet.

[0010] As a preferred embodiment of the above technical solution, the length of the notch is greater than the length of the slot. When the protrusion moves to the notch, the protrusion rotates at the notch. When the protrusion moves to the slot, the protrusion is locked in the slot.

[0011] As a preferred embodiment of the above technical solution, when the top of the sliding plate abuts against the top of the movable cavity, the protrusion is engaged in the slot.

[0012] As a preferred embodiment of the above technical solution, the electric water heater body is equipped with a power board, a processor, a photoelectric tilting device, an alarm, and a display screen. The power board is connected to the processor, the photoelectric tilting device, the alarm, and the display screen, and the photoelectric tilting device and the alarm are connected to the processor.

[0013] As a preferred embodiment of the above technical solution, an electric heating element is installed on the electric water heater body, and a temperature sensor is installed on the part of the electric heating element located in the inner cavity of the electric water heater body, and the temperature sensor is connected to the processor.

[0014] As a preferred embodiment of the above technical solution, an indicator sign is affixed to the electric water heater body.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, when installing the electric water heater body, the sliding plate can move downwards due to its own weight when it is in a vertical state, which allows the ratchet to rotate and the gear to rotate, so that the hook can be installed into the installation groove. When the sliding plate is in a horizontal state, due to the elasticity of the elastic element, one end of the sliding plate abuts against one end of the movable cavity. At this time, the ratchet is stuck in the slot. If the hook is put into the installation groove at this time, the ratchet cannot rotate because it is stuck, so the gear cannot rotate. Thus, the hook cannot enter the installation groove, and the installation of the electric water heater body cannot be completed. This can effectively prevent users from installing the electric water heater body in the wrong direction and ensure that the electric water heater body can work normally after installation.

[0017] 2. In this utility model, while the ratchet, sliding plate and gear are engaged, the photoelectric tilting device enables the user to determine whether the installation direction of the electric water heater body 1 is correct when the wall is tilted at a certain angle, thereby improving the installation efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-4 As shown, an electric water heater designed to prevent tipping includes a water heater body 1, and the water heater further includes:

[0027] Hook 2, hook 2 includes an outer plate 21, an inner plate 22, a connecting block 23 and gears 24. The outer plate 21 is fixedly connected to the surface of the electric water heater body 1. Several gears 24 are rotatably installed between the outer plate 21 and the inner plate 22. The outer plate 21 and the inner plate 22 are fixedly connected by the connecting block 23.

[0028] The hanging plate 3 and the hook 2 are designed separately. Several mounting seats 4 are fixed on one side of the hanging plate 3. The mounting seats 4 have mounting grooves 41, and the hook 2 is inserted into the mounting grooves 41.

[0029] The sliding plate 6 and the mounting base 4 also have a movable cavity 42. The sliding plate 6 is slidably installed in the movable cavity 42. A fixing plate 61 is fixed at the bottom of the movable cavity 42. The fixing plate 61 is fitted inside the sliding plate 6. An elastic element 62 connects the fixing plate 61 and the sliding plate 6.

[0030] The ratchet 5 has several through holes 43 in the mounting base 4, which connect the mounting groove 41 and the movable cavity 42. The ratchet 5 is elastically rotatably connected at the through holes 43. The slide plate 6 has several notches 63 and slots 64 on the side near the ratchet 5. The ratchet 5 is provided with a protrusion 51. One notch 63 and one slot 64 are a pair corresponding to one protrusion 51 on the ratchet 5. The notch 63 corresponding to the ratchet 5 is located above the slot 64 corresponding to this ratchet 5.

[0031] Furthermore, the length of the notch 63 is greater than the length of the slot 64. When the protrusion 51 moves to the notch 63, the protrusion 51 rotates at the notch 63. When the protrusion 51 moves to the slot 64, the protrusion 51 is locked in the slot 64.

[0032] Furthermore, when the top of the slide plate 6 abuts against the top of the movable cavity 42, the protrusion 51 is engaged in the slot 64.

[0033] In one embodiment, the elastic element 62 can be a spring or other elastically extendable component; the slide plate 6 has a certain weight. When the mounting base 4 is in a vertical state, the slide plate 6 will move down due to its own weight. When the mounting base 4 is in a horizontal state, the slide plate 6 will return to its original position due to the elasticity of the elastic element 62.

[0034] In practical application, before installing the electric water heater body 1, the split mounting plate 3 is first fixed to the wall of the electric water heater body 1 to be installed using bolts and other fixing components. Then, the hook 2 is put into the mounting groove 41 from top to bottom. Before installing the hook 2, due to the weight of the sliding plate 6, the sliding plate 6 moves downward, so that the protrusion 51 on the ratchet 5 is located in the notch 63, so that the ratchet 5 can rotate. When the hook 2 is put into the mounting groove 41, the gear 24 will contact the ratchet 5. Since the ratchet 5 can rotate, the gear 24 can move into the mounting groove 41 without obstruction, that is, it is not obstructed when installing the hook 2. This is the correct method for installing the electric water heater body 1.

[0035] When the user installs the electric water heater body 1 horizontally for convenience or due to limited installation space, the mounting plate 3 and the mounting base 4 are both horizontal. In this horizontal state, due to the rebound ability of the elastic element 62, one end of the sliding plate 6 abuts against one end of the movable cavity 42. At this time, the ratchet 5 is stuck in the slot 64. If the hook 2 is then put into the mounting slot 41, the ratchet 5 will be stuck and unable to rotate, thus preventing the gear 24 from rotating. In this way, the hook 2 cannot enter the mounting slot 41, and the installation of the electric water heater body 1 cannot be completed. This effectively prevents the user from installing the electric water heater body 1 in the wrong direction and ensures that the electric water heater body 1 can work normally after installation.

[0036] like Figure 1 and Figure 5 As shown, the electric water heater body 1 is equipped with a power board 7, a processor 8, a photoelectric tilting device 9, an alarm 10, and a display screen 11. The power board 7 is connected to the processor 8, the photoelectric tilting device 9, the alarm 10, and the display screen 11. The photoelectric tilting device 9 and the alarm 10 are connected to the processor 8.

[0037] It should be noted that the wall on which the electric water heater body 1 is to be installed may not be vertical or may be tilted. If the tilt angle of the wall is small, it may not affect the normal operation of the electric water heater body 1. If the tilt angle of the wall is large, it may affect the normal operation of the electric water heater body 1. Moreover, when the mounting plate 3 is tilted, the sliding plate 6 may still slide along the movable cavity 42, making it impossible for the user to determine whether the installation direction of the electric water heater body 1 is correct during installation.

[0038] In one embodiment, the photoelectric tilting device 9 can be a photoelectric tilting switch. The power board 7, processor 8, photoelectric tilting device 9, alarm 10 and display screen 11 are all prior art. This application does not improve them. Therefore, it is not necessary to disclose their specific mechanical structure and circuit structure, and it does not affect the integrity of this application.

[0039] In practical application, after the electric water heater body 1 is installed, power is supplied to the electric water heater body 1, which in turn powers the power board 7. At this time, the photoelectric tilting device 9 operates. The photoelectric tilting device 9 automatically detects the installation angle of the electric water heater body 1. Generally, when the installation direction of the electric water heater body 1 is at 90°±35° with the horizontal plane, the photoelectric tilting device 9 will send a high-level signal to the processor 8. The processor 8 will then transmit the signal to the display screen 11 for display and enable the display screen 11 to operate normally. At the same time, the alarm 10 will not sound an alarm, thus allowing the user to operate and control the electric water heater body 1 normally. That is, the installation direction of the electric water heater body 1 allows it to tilt normally. When the angle between the installation direction of the electric water heater body 1 and the horizontal plane is not 90°±35°, the photoelectric tilting device 9 will send a low-level signal to the processor 8. The processor 8 will then transmit the signal to the display screen 11 for display and make the display screen 11 unable to operate normally. At the same time, the alarm 10 will sound an alarm bell, thus preventing the user from operating the electric water heater body 1 normally. That is, the installation direction of the electric water heater body 1 cannot enable the electric water heater body 1 to work normally. Through the cooperation of the photoelectric tilting device 9 with the ratchet 5, the sliding plate 6 and the gear 24, the user can determine whether the installation direction of the electric water heater body 1 is correct when the wall is at a certain tilt angle, thereby improving the installation efficiency.

[0040] Furthermore, an electric heating element 12 is installed on the electric water heater body 1, and a temperature sensor 13 is installed on the part of the electric heating element 12 located inside the electric water heater body 1. The temperature sensor 13 is connected to the processor 8.

[0041] In one embodiment, the temperature sensor 13 is existing technology, and this application does not improve upon it. Therefore, it is not necessary to disclose its specific mechanical and circuit structures, and this does not affect the integrity of this application. The heating element 12 is connected to the power board 7 via a connecting wire, and the power board 7 can control the heating element 12 to start or stop working via the processor 8.

[0042] In practical application, after the electric water heater body 1 is installed, if the photoelectric tilting device 9 is damaged, making it impossible for the user to determine whether the installation direction of the electric water heater body 1 is correct when the wall is tilted at a certain angle, water can be added to the electric water heater body 1. When the water level reaches a certain height, the heating element 12 will start working to heat the water. The temperature sensor 13 will detect the temperature of the heating element 12 in real time. If there is an abnormal temperature rise, the processor 8 will transmit a signal to the power board 7 and the alarm 10. The alarm 10 will sound an alarm, and the power board 7 will cut off the power to the heating element 12. This indicates that the installation direction of the electric water heater body 1 is incorrect, and vice versa.

[0043] like Figure 1 As shown, an indicator sign 14 is affixed to the electric water heater body 1.

[0044] In one embodiment, the orientation of the indicator 14 is the same as the orientation of the water inlet pipe of the electric water heater body 1, both facing upwards.

[0045] In practical application, users can initially determine the installation direction of the electric water heater body 1 by observing the direction of the indicator 14, thereby improving the efficiency of subsequent installation and also ensuring that the installation direction of the electric water heater body 1 is correct.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
