DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] The concealed electric water heater of the present invention is as follows Figure 2 As shown, the electric water heater main unit 1 for hiding in the wall 99 and the bracket 3 for fixing in the wall 99, the electric water heater main unit 1 includes a main unit housing 11, the main unit housing 11 can be made of plastic, the main unit housing 11 can play a role in heat insulation, and the main unit housing 11 is slidably arranged on the bracket 3. Figure 2 As shown, the concealed electric water heater of the present invention further includes a driving assembly 6, which includes a motor assembly 61, a screw 62 and a nut 63. The screw 62 is extended in the front-back direction, and the screw 62 is adapted to be connected with the nut 63. The motor assembly 61 drives the screw 62 to rotate. Specifically, the motor assembly 61 is provided with an output shaft, and the output shaft is coaxially arranged with the screw 62. The output shaft and the screw 62 can be connected by a flat key, and the nut 63 is connected to the main housing 11 by screws. Figure 1 and Figure 2 As shown, the concealed electric water heater of the present invention further comprises a cover 2 and a shower head 4. The cover 2 is mounted on the front side of the main housing 11. In other words, the cover 2 can cover the front opening of the main housing 11. The cover 2 can be connected to the front opening edge of the main housing 11 by corresponding screws. A tile receiving frame 21 is formed at the front end of the cover 2. Figure 3As shown, the lower end of the electric water heater main body 1 is provided with a water outlet 1202, and the shower head 4 is connected to the water outlet 1202 through a shower hose 41. The shower hose 41 can be arranged outside the main body housing 11, and the right outer side of the main body housing 11 is provided with an insertion box 15 for inserting the shower head 4 downward, that is, the opening of the insertion box 15 is upward, and the insertion box 15 can be integrated with the main body housing 11, as shown in FIG. Figure 1 Combination Figure 3 As shown, the shower head 4 and the shower hose 41 can be placed on the rear side of the cover 2. In other words, the peripheral portion of the cover 2 protrudes from the main housing 11, so when viewed from the front, the peripheral portion of the cover 2 can cover the shower head 4 and the shower hose 41.

[0024] like Figure 1 As shown, a pit is dug on the wall 99, the bracket 3 is installed at the bottom of the pit, and tiles are arranged in the tile receiving frame 21 of the cover 2. The tiles in the tile receiving frame 21 are the same as the tiles on the wall 99, and the tiles in the tile receiving frame 21 can be flush with the tiles on the wall 99, so the electric water heater of the present invention can be hidden in the wall 99, that is, the front end of the pit is adapted to the shape of the cover 2. The motor assembly 61 drives the screw 62 to rotate, and since the nut 63 is installed and connected to the main housing 11, the screw 62 can drive the main housing 11 to move forward and backward. When the electric water heater needs to be used, the motor assembly 61 drives the electric water heater main body 1 and the cover 2 to move forward, so that the shower head 4 and the shower hose 41 are moved out to the front of the wall 99, and then the shower head 4 is upwardly removed from the plug box 15 with the right hand, and the shower hose 41 is wound (counterclockwise) away from the main body shell 11, and the electric water heater can be used normally; when the electric water heater is finished using, the shower hose 41 is wound clockwise around the outside of the main body shell 11, and the shower head 4 is placed downward into the plug box 15. At this time, the shower head 4 is in an upright state, and the shower head 4 and the shower hose 41 are located at the rear side of the cover 2, so the motor assembly 61 drives the electric water heater main body 1 and the cover 2 to move backward, and the shower head 4 and the shower hose 41 will not touch the wall 99, and the electric water heater is completely hidden. Since the tile accommodating frame 21 is provided with tiles, the position where the electric water heater is hidden on the wall 99 is not easy to be detected as abnormal, so the hidden electric water heater of the present invention can reduce the influence of the electric water heater on the bathroom decoration effect. The electric water heater is switched between the use position and the hidden position by electric driving, which is conducive to the convenient hiding of the electric water heater of the present invention. By arranging the plug box 15 on the right outer side of the main housing 11, the shower head 4 is prevented from flipping or shaking when the main housing 11 moves forward and backward, and the shower head 4 is prevented from hitting the wall 99. It is convenient for right-handed users to use it, and the shower hose 41 can be prevented from being pulled by the shower head 4 due to the shower head 4 being hung for a long time. The present invention can hide both the shower head 4 and the shower hose 41, so the hiding effect is particularly good.

[0025] Furthermore, if Figure 2 and Figure 3 As shown, the main housing 11 is formed with a rear plate 111, as shown in FIG. Figure 3 As shown, a barrel portion 112 is formed in the middle of the rear plate 111. Figure 2 As shown, the bracket 3 includes a mounting plate 31 and a guide post 32. The rear end of the guide post 32 is fixedly connected to the mounting plate 31. The mounting plate 31 and the guide post 32 can be made of stainless steel. The rear end of the guide post 32 is adapted to be plugged into the mounting plate 31. The guide post 32 and the mounting plate 31 can be welded. The barrel 112 is slidably connected to the guide post 32. Specifically, as shown in FIG. Figure 4 As described above, the barrel 112 may be formed with a sliding hole 1121, the guide post 32 is adapted to pass through the corresponding sliding hole 1121, the screw 62 is arranged on the inner side of the barrel 112, the screw 62 is preferably arranged coaxially with the barrel 112, the guide posts 32 are distributed on the outer side of the screw 62, and the guide posts 32 are preferably evenly distributed around the axis of the screw 62, such as Figure 2 As shown, the outer periphery of the nut 63 is connected to the barrel 112. Specifically, the rear portion of the nut 63 is adapted to be disposed in the barrel 112, and a flange structure is formed on the outer periphery of the nut 63. The flange structure is mounted on the front end surface of the barrel 112 by corresponding screws; Figure 2 As shown, the motor assembly 61 is installed on the front side of the mounting plate 31; through the above arrangement, the bracket 3 supports the middle position of the main housing 11, so that the bracket 3 can be set as a single one, that is, it is avoided to configure a plurality of brackets 3 to disperse and support the peripheral part of the main housing 11, which is conducive to simplifying the installation process of the bracket 3 in the above pit, and avoids the electric water heater main body 1 from getting stuck during the forward and backward movement due to unbalanced force. When the electric water heater main body 1 moves forward and backward, the guide column 32 slides relatively forward and backward in the corresponding sliding hole 1121, and a baffle can be installed on the front end surface of the guide column 32, so that the cylinder 112 is limited to travel between the above baffle and the mounting plate 31.

[0026] Furthermore, if Figure 2 and Figure 3 As shown, the electric water heater main unit 1 includes a heating unit 12, and the heating unit 12 is arranged in the main unit housing 11. An avoidance hole 1201 is formed in the middle of the heating unit 12, and the barrel 112 is arranged on the inner side of the avoidance hole 1201. In other words, when viewed from the front, the heating unit 12 is ring-shaped, so that the heating unit 12 can be prevented from being biased to one side, resulting in insufficient available arrangement space for the heating unit 12. It can also be understood that it is beneficial to set the volume of the heating unit 12 larger, and it is also beneficial to make the center of gravity of the electric water heater main unit 1 centered, which is beneficial to balance the support force of the bracket 3 on the electric water heater main unit 1.

[0027] Furthermore, if Figure 5 As shown, the heating unit 12 is provided with a heated water pipe 121. Figure 3As shown, the lower end of the electric water heater main body 1 is provided with a water inlet 1201, the water inlet 1201 is connected to one end of the heated water pipe 121, and the water outlet 1202 is connected to the other end of the heated water pipe 121. Figure 5 As shown, the heated water pipe 121 may be spirally wound around the outer side of the avoidance hole 1201 ( Figure 5 The heated water pipe 121 is only schematically shown by a dotted line. Figure 3 As shown, an electric flow control valve 124 is provided between the water inlet 1201 and the heated water pipe 121. The electric flow control valve 124 belongs to the prior art. For example, the "electric flow control valve" of the Chinese utility model patent publication number CN201636402U can be referred to. Therefore, the tap water input to the water inlet 1201 passes through the electric flow control valve 124 before reaching the heated water pipe 121. The electric flow control valve 124 can adjust the water flow entering the heating unit 12, thereby controlling the water flow of the shower head 4. Figure 3 As shown, the water inlet 1201 is connected to the water pipe through the water inlet hose 13, and the water pipe is buried in the wall 99, so when the electric water heater main unit 1 moves forward and backward, the water inlet hose 13 can move.

[0028] Furthermore, if Figure 5 As shown, a water outlet temperature sensor 126 is provided between the water outlet 1202 and the heated water pipe 121. The heating unit 12 includes an electric heating pipe 122 and an aluminum shell 120. The electric heating pipe 122 and the heated water pipe 121 are provided in the aluminum shell 120. Thus, the water outlet temperature of the electric water heater can be monitored by the water outlet temperature sensor 126. Figure 2 As shown, the aluminum shell 120 can be coated on the heated water pipe 121 and the electric heating pipe 122 through a casting process, and the electric heating pipe 122 is roughly in a circular shape; the heat generated by the electric heating pipe 122 is transferred to the heated water pipe 121 through the aluminum shell 120, thereby heating the water flowing through the heated water pipe 121. The heated water pipe 121 can be wound in two layers, front and back, so that the heated water pipe 121 forms two front and back disc-shaped structures, and the electric heating pipe 122 is located between the two above-mentioned disc-shaped structures, which is conducive to the heated water pipe 121 to fully absorb the heat generated by the electric heating pipe 122.

[0029] Furthermore, if Figure 2As shown, a control circuit board 5 is provided in the main housing 11, and the control circuit board 5 can be installed on the rear side of the cover 2. The control circuit board 5 is electrically connected to the outlet water temperature sensor 126. The control circuit board 5 controls the connection of the electric flow control valve 124, the electric heating pipe 122 and the motor assembly 61. The electric water heater of the present invention also includes a remote controller, and the control circuit board 5 is wirelessly connected to the remote controller. For example, the remote controller can be connected to the control circuit board 5 via Bluetooth; the control circuit board 5 can monitor the outlet water temperature of the electric water heater through the outlet water temperature sensor 126. When the outlet water temperature is higher than the set value, the control circuit board 5 can control the electric heating pipe 122 to cut off the power. When the outlet water temperature is lower than the set value, the control circuit board 5 can control the electric heating pipe 122 to resume work, so that the outlet water temperature is stable. The user can set the control circuit board 5 through the remote controller to control the outlet water temperature of the electric water heater. When the user presses the flow increase button on the remote controller, the control circuit board 5 receives the instruction issued by the remote controller and controls the electric flow control valve 124 to increase the water inlet flow accordingly. Similarly, the user can reduce the outlet water flow of the electric water heater through the remote controller. The motor assembly 61 can be a stepper motor. When the user presses the forward button on the remote control, the control circuit board 5 receives the forward instruction and controls the motor assembly 61 to drive the electric water heater main unit 1 to move forward to the use position. Similarly, the user can control the electric water heater main unit 1 to move backward to the hidden position through the remote control. By setting the remote control, it is convenient for the user to control the electric water heater. Figure 3 As shown, an overheat protection thermostat 127 may be provided on the outside of the aluminum shell 120. The overheat protection thermostat 127 is a prior art. For example, reference may be made to "A large current bipolar overheat protection thermostat" with Chinese utility model patent publication number CN208706538U.

[0030] Furthermore, if Figure 2 and Figure 6 As shown, the surface cover 2 is formed with a front supporting surface 201 for abutting against the back of the tile, and a mesh pattern is formed on the front supporting surface 201, that is, the mesh pattern is a mesh-shaped concave pattern, so that the back of the tile can be coated with glass glue, and then the tile is fitted into the tile receiving frame 21, and then the back of the tile is abutted against the front supporting surface 201. The mesh pattern can enhance the effect of the glass glue adhering to the surface cover 2, and can prevent the tile from falling out of the tile receiving frame 21.

[0031] Furthermore, if Figure 6 As shown, the tile receiving frame 21 is set as a rectangular frame, so it is convenient to cut the tiles straightly to match the shape of the tile receiving frame 21. If the individual area of ​​the original tiles on the wall 99 is small, the tiles can be assembled in the tile receiving frame 21. Since the tile receiving frame 21 is set as a rectangular frame, it is relatively easy to open the above-mentioned pit on the wall 99.

[0032] Furthermore, if Figure 1As shown, a positioning groove 1101 for accommodating the shower hose 41 is formed at the upper end of the main housing 11. Therefore, after the electric water heater is used, when the shower hose 41 is wrapped around the outside of the main housing 11 by hand, the upper part of the shower hose 41 is stuck in the positioning groove 1101, which is conducive to stabilizing the position of the shower hose 41 relative to the main housing 11 and facilitating the electric water heater to be stably reset to the hidden position.
