Description

Technical Field

[0001] This utility model relates to the field of household appliance technology and discloses an outer casing assembly and an electric water heater. Background Technology

[0002] Some electric water heaters are now equipped with human body sensors. These sensors detect human movement in front of the water heater and control the display screen on or off to reduce the overall energy consumption of the water heater.

[0003] However, in most related technologies, human body sensors are fixed to the water heater casing with screws. When the human body sensor malfunctions, all the screws need to be removed before the human body sensor can be removed from the water heater casing. This makes the disassembly and installation of the human body sensor inconvenient, resulting in relatively low maintenance efficiency and increased labor and time costs. Utility Model Content

When removing the human body sensor from the outer casing, the mounting box can be directly removed, thus completing the disassembly of the human body sensor, effectively improving the disassembly efficiency and facilitating user maintenance and installation. Installing the human body sensor probe within the mounting box and extending beyond it ensures that the probe can normally transmit and receive detection signals, thereby detecting human movement.

[0010] In one embodiment, the outer cover has a mounting surface for mounting a display panel, and the human body sensing probe is mounted in the mounting box facing the mounting surface and tilted downwards.

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] According to embodiments of the present invention, such as Figures 1 to 6 As shown, an outer cover assembly is provided, including: an outer cover 10, the bottom of which is provided with a mounting groove 110 extending from the outer surface of the outer cover 10 to the inside of the outer cover 10; and a human body sensing device 20, including a human body sensing probe 220 and a mounting box 210, the human body sensing probe 220 being installed in the mounting box 210 and extending out of the mounting box 210, the mounting box 210 being snapped into the mounting groove 110.

[0034] In this embodiment, a mounting groove 110 is formed by recessing from the outer surface of the outer cover 10 to the inside of the outer cover 10 at the bottom, providing a receiving space for the human body sensor 20, which can be installed into the mounting groove 110. The human body sensor 20 consists of a mounting housing 210 and a human body sensor probe 220. The mounting housing 210 is detachably snapped into the mounting groove 110 without the need for screws or bolts or other connecting structures. When removing the human body sensor 20 from the outer cover 10, the mounting housing 210 can be directly removed from the outer cover 10, thereby completing the disassembly of the human body sensor 20, effectively improving the disassembly efficiency of the human body sensor 20 and facilitating user maintenance and installation. Installing the human body sensor 220 inside and extending out of the mounting box 210 can protect the human body sensor 220. Extending the human body sensor 220 out of the mounting box 210 also ensures that the human body sensor 220 can normally transmit and receive detection signals, thereby detecting human movement. Optionally, by detecting human movement through the human body sensor 220, and then controlling the opening or closing of the water heater display panel 30 based on the detection signal, the overall energy consumption of the water heater can be effectively reduced.

[0035] like Figures 4 to 6 As shown, in one embodiment, the outer casing 10 has a mounting surface 130 for mounting the display panel 30, and the human body sensor 220 is mounted inside the mounting housing 210 facing the mounting surface 130 and tilted downwards. Further, the tilt angle of the human body sensor 220 is 30°-60°.

[0036] In this embodiment, a mounting surface 130 is provided on the outer cover 10. The mounting surface 130 is located on the side of the outer cover 10 and faces the human activity area. A display panel 30 is provided on the mounting surface 130, which facilitates user operation. By facing the mounting surface 130 and installing it at an angle downwards inside the mounting housing 210, the human body sensing probe 220 has a certain tilt angle, which allows the human body sensing probe 220 to better detect human activity in a specific area, ensuring the signal reception range and signal reception effect of the human body sensing probe 220. For example, when someone passes by in front of the electric water heater, the human body sensing probe 220 can accurately sense the presence of the human body within an effective distance, thereby obtaining a detection signal of human movement. The tilt angle of the human body sensing probe 220 can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc., and can be set according to actual usage needs without specific limitations.

[0037] like Figure 3 , Figure 4As shown, in one embodiment, the mounting groove 110 is provided with a plurality of slots 120, and the mounting box 210 is provided with a plurality of buckles 212. The buckles 212 are configured to correspond one-to-one with the slots 120. The human body sensing device 20 is engaged with the outer cover 10 by the buckles 212 and the slots 120.

[0038] In this embodiment, a plurality of slots 120 are provided on the mounting groove 110, and the slots 120 are all located on the top and side walls of the mounting groove 110. Simultaneously, a plurality of buckles 212 are provided on the mounting box 210, and the buckles 212 are all located on the side walls of the mounting box 210. Each buckle 212 corresponds one-to-one with a slot 120, ensuring that each buckle 212 on the mounting box 210 accurately engages with the corresponding slot 120 on the mounting groove 110. When a buckle 212 is inserted into a slot 120 and fastened, the human body sensor 20 is fixed in the mounting groove 110, thereby achieving engagement with the outer cover 10. The snap-fit ​​connection between the snap-fit ​​212 and the slot 120 improves the ease of installation of the human body sensor 20 and ensures the reliability of the connection, preventing the human body sensor 20 from loosening or falling off during use. When the human body sensor 20 malfunctions and needs to be repaired or replaced, the mounting box 210 can be quickly removed from the outer cover 10, thereby improving the efficiency of disassembling or installing the human body sensor 20.

[0039] In one embodiment, the bottom of the mounting box 210 is provided with an inclined mounting wall 215, and the mounting wall 215 is provided with a first through hole 213, through which the human body sensing probe 220 extends out of the mounting box 210.

[0040] In this embodiment, an inclined mounting wall 215 is provided at the bottom of the mounting box 210, creating an angle between the mounting wall 215 and the vertical direction. When the human body sensor 220 is installed inside the mounting box 210, it better ensures that the human body sensor 220 forms a target angle with the vertical direction, thereby ensuring the signal reception range and signal reception effect of the human body sensor 220. A first through hole 213 is provided on the mounting wall 215. The human body sensor 220 is partially disposed inside the mounting box 210, while its head extends out of the mounting box 210 through the first through hole 213. This allows the detection range of the human body sensor 220 to be unaffected by the mounting box 210, further ensuring that the detection range of the human body sensor 220 can cover the target detection area, such as the human activity area in front of an electric water heater. The shape of the first through hole 213 can be circular, square, or other shapes adapted to the head of the human body sensor 220, and is not specifically limited here.

[0041] like Figures 4 to 6As shown, in one embodiment, the human body sensor 220 has a circuit board 222 at one end located in the mounting groove 110, a limiting step 221 on the outer wall of the human body sensor 220, a limiting protrusion 211 in the mounting box 210, one end of the human body sensor 220 abuts against the mounting wall 215 through the limiting step 221, and the other end abuts against the limiting protrusion 211 through the circuit board 222.

[0042] In this embodiment, a circuit board 222 is provided at one end of the human body sensor probe 220 located in the mounting groove 110 for processing the detection signal and electrically connecting it to the display panel 30 of the electric water heater. A limiting step 221 is provided on the outer wall of the human body sensor probe 220. When the head of the human body sensor probe 220 extends out of the mounting box 210 from the first through hole 213, the limiting step 221 can abut against the mounting wall 215, which can fix the human body sensor probe 220 while preventing the human body sensor probe 220 from extending excessively out of the mounting box 210.

[0043] Limiting protrusions 211 are provided on the inner wall of the mounting box 210, and are respectively located on both sides of the inner wall of the mounting box 210. When the human body sensor 220 is installed in the mounting box 210, one end of the human body sensor 220 can abut against the limiting protrusion 211 on the inner wall of the mounting box 210 through the circuit board 222; the other end can abut against the mounting wall 215 through the limiting step 221, thereby locking the human body sensor 220 on the mounting box 210 and preventing the human body sensor 220 from moving forward or backward; moreover, when it is necessary to replace or repair the human body sensor 220, the human body sensor 220 can be easily removed from the mounting box 210, which facilitates the installation and maintenance of the human body sensor 220.

[0044] In one embodiment, the human body sensing device 20 further includes a sealing ring 240, which is sleeved on the human body sensing probe 220 and abuts against the side wall of the first through hole 213 and the limiting step 221 of the human body sensing probe 220.

[0045] In this embodiment, since electric water heaters are typically installed in bathrooms, the human body sensor 20 is constantly exposed to high humidity, making it susceptible to short circuits due to moisture intrusion. By installing a sealing ring 240 inside the mounting housing 210, and fitting the sealing ring 240 onto the human body sensor probe 220, with the sealing ring 240 abutting between the side wall of the first through hole 213 and the limiting step 221 of the human body sensor probe 220, moisture from the bathroom cannot enter the mounting housing 210 through the first through hole 213. This prevents the wiring of the human body sensor 20 from being exposed to high humidity, reducing the likelihood of short circuits and thus decreasing the frequency of repairs and extending the lifespan of the human body sensor 20.

[0046] like Figures 1 to 3 As shown, in one embodiment, the human body sensing device 20 further includes a sealing plug 230, and the mounting housing 210 has a mounting groove 214, into which the sealing plug 230 is inserted. The outer casing assembly also includes a connecting wire 250, and the sealing plug 230 has a second through hole 231, through which the connecting wire 250 passes and connects to the human body sensing probe 220. Further, the outer casing assembly also includes a display panel 30, which is mounted on the mounting surface 130 and electrically connected to the human body sensing probe 220 via the connecting wire 250.

[0047] In this embodiment, the sealing plug 230 is made of an elastic material, specifically a silicone plug or a rubber plug, which has good sealing properties and deformation recovery ability. A mounting groove 214 is also provided on the mounting box 210, allowing the sealing plug 230 to be inserted into the mounting groove 214 and abut against the inner wall of the mounting groove 214. When the sealing plug 230 is inserted into the mounting groove 214, one end of the sealing plug 230 extends out of the groove 214 from the opening of the groove. When the mounting box 210 is installed into the mounting recess 110, the sealing plug 230 extending from the mounting groove 214 is pressed tightly, thereby abutting against the inner wall of the mounting recess 110, ensuring that the sealing plug 230 is in close contact with both the mounting groove 214 and the inner wall of the mounting recess 110, thus preventing water from entering the interior of the mounting box 210.

[0048] Furthermore, a second through hole 231 is provided on the sealing plug 230, allowing the connecting wire 250 to pass through the second through hole 231 and enter the mounting housing 210, thereby connecting one end of the connecting wire 250 to the circuit board 222 of the human body sensing probe 220. A display panel 30 is also mounted on the mounting surface 130 of the outer cover 10, and the other end of the connecting wire 250 is connected to the display panel 30, thereby realizing the electrical connection between the display panel 30 and the human body sensing probe 220, allowing the user to control the human body sensing function to be turned on or off on the display panel 30.

[0049] In other possible implementations, the human body sensor 220 is connected to the display panel 30 via a mating terminal. The electrical connection between the human body sensor 220 and the display panel 30 is achieved by mating the male and female terminals on the connecting cable 250.

[0050] On the other hand, this utility model also provides an electric water heater, including: an electric water heater body; and an outer cover assembly, the outer cover assembly being installed at the bottom of the electric water heater body. Since the electric water heater includes the aforementioned outer cover assembly and has the same effect as the outer cover assembly, it will not be described in detail here.

[0051] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0052] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
