DETAILED DESCRIPTION

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

[0023] The utility model of the hidden electric water heater, such as Figure 2 As shown, the electric water heater main unit 1 is used to be hidden in the wall 99 and the bracket 3 is used to be fixed 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 and can play a role in heat insulation. The main unit housing 11 is slidable forward and backward on the bracket 3. Figure 2 As shown, the hidden electric water heater of the present invention further includes a drive assembly 6, which includes a motor assembly 61, a screw 62 and a nut 63. The screw 62 extends in the front-to-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, which 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 includes a cover 2 and a shower head 4. The cover 2 is mounted on the front side of the main body housing 11. In other words, the cover 2 can cover the front opening of the main body housing 11. The cover 2 can be connected to the front opening edge of the main body 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 wound around the outside of the main body housing 11. The right outer side of the main body housing 11 is provided with a plug-in box 15 for inserting the shower head 4 downward, that is, the opening of the plug-in box 15 is upward, and the plug-in box 15 can be integrated with the main body housing 11, as shown in FIG. Figure 1 Combine 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 outer periphery of the cover 2 protrudes from the main housing 11. Thus, when viewed from the front, the outer periphery of the cover 2 can shield the shower head 4 and the shower hose 41.

[0024] like Figure 1 As shown, a recess is formed in the wall 99, the bracket 3 is mounted at the bottom of the recess, and tiles are placed in the tile receiving frame 21 of the cover 2. The tiles in the tile receiving frame 21 are the same type as those on the wall 99, and the tiles in the tile receiving frame 21 can be flush with the tiles on the wall 99, so that the electric water heater of the present invention can be hidden in the wall 99. In other words, the front end of the recess is adapted to the shape of the cover 2. The operation of the motor assembly 61 drives the screw 62 to rotate. Since the nut 63 is mounted and connected to the main body housing 11, the screw 62 can drive the main body 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 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) out of the 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 body shell 11, and the shower head 4 is lowered 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 that the motor assembly 61 drives the electric water heater 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 hidden. Since tiles are provided in the tile receiving frame 21, the position where the electric water heater is hidden on the wall 99 is not easy to be noticed. Therefore, the concealed electric water heater of the present invention can reduce the impact of the electric water heater on the bathroom decoration effect. The electric water heater is electrically driven to switch between an operational position and a concealed position, making it convenient for concealment. The insertion box 15 is positioned on the right outer side of the main body housing 11 to prevent the shower head 4 from flipping or shaking when the main body housing 11 is moved back and forth, thereby preventing the shower head 4 from hitting the wall 99. This also makes it easier for right-handed users to use the water heater and prevents the shower hose 41 from being damaged by the shower head 4 due to prolonged hanging. The present invention conceals both the shower head 4 and the shower hose 41, resulting in an exceptionally effective concealment.

[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 cylindrical 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 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 provided on the inner side of the barrel 112, the screw 62 is preferably provided 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, as shown in FIG. 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. The outer periphery of the nut 63 is formed with a flange structure, which is mounted on the front end surface of the barrel 112 by corresponding screws. Figure 2 As shown, the motor assembly 61 is mounted on the front side of the mounting plate 31. By configuring the bracket 3 to support the central portion of the main unit housing 11, the bracket 3 can be provided as a single arrangement, avoiding the need for multiple brackets 3 to dispersely support the peripheral portions of the main unit housing 11. This simplifies the installation process of the bracket 3 within the aforementioned recess and prevents the main unit 1 from becoming stuck during forward and backward movement due to unbalanced force. When the main unit 1 moves forward and backward, the guide post 32 slides relative to the corresponding slide hole 1121. A baffle can be installed on the front face of the guide post 32 to limit the travel of the barrel 112 between the 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, which is arranged in the main unit housing 11. An avoidance hole 1200 is formed in the middle of the heating unit 12, and the barrel 112 is arranged on the inner side of the avoidance hole 1200. In other words, when viewed from the front, the heating unit 12 is annular, so it can avoid the need for the heating unit 12 to be offset to one side, resulting in insufficient available arrangement space for the heating unit 12. It can also be understood that it is beneficial for the volume of the heating unit 12 to be set larger, and it is also beneficial for the center of gravity of the electric water heater main unit 1 to be centered, which is beneficial for the electric water heater main unit 1 to be supported by the bracket 3. Balance the force.

[0027] Furthermore, if Figure 5 As shown, a heated water pipe 121 is provided in the heating unit 12. Figure 3As shown, the lower end of the electric water heater main unit 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 can be spirally wound around the outside of the avoidance hole 1200 ( 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 installed between the water inlet 1201 and the heated water pipe 121. The electric flow control valve 124 belongs to the prior art. For example, please refer to the "Electric Flow Control Valve" of Chinese Utility Model Patent Publication No. CN201636402U. 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 out 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 covered on the outside of the heated water pipe 121 and the electric heating pipe 122 by 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. 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 control. The control circuit board 5 is wirelessly connected to the remote control. For example, the remote control can connect 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 operation so that the outlet water temperature is stable. The user can set the control circuit board 5 through the remote control to control the outlet water temperature of the electric water heater. When the user presses the flow increase button on the remote control, the control circuit board 5 receives the instruction from the remote control and controls the electric flow control valve 124 to increase the water inlet flow. Similarly, the user can reduce the water outlet flow of the electric water heater through the remote control. 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 into the use position. Similarly, the user can control the electric water heater main unit 1 to move backward into the hidden position through the remote control. By setting up a 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" of 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 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 configured as a rectangular frame, which facilitates straight-line cutting of tiles to match the shape of the tile receiving frame 21. If the individual tiles on the wall 99 are relatively small, the tiles can be arranged within the tile receiving frame 21. Since the tile receiving frame 21 is configured as a rectangular frame, it is relatively easy to create the aforementioned recess 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 body housing 11. Therefore, after using the electric water heater, when the shower hose 41 is manually wrapped around the outside of the main body housing 11, the upper portion of the shower hose 41 is locked into the positioning groove 1101, which helps to stabilize the position of the shower hose 41 relative to the main body housing 11 and facilitates the stable reset of the electric water heater to the hidden position.
