Description

Technical Field

[0001] This utility model relates to the field of electric water heater technology, and in particular to an adaptive electric water heater. Background Technology

[0002] To adapt to market demands, many electric water heaters now accommodate different installation spaces, operating in either horizontal or vertical configurations. However, the control display screen of these water heaters cannot adjust accordingly to the installation method, leading to inconvenience and a poor user experience. To address these issues, a solution is provided below. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an adaptive electric water heater with an adaptive control display screen, which solves the problem that the installation position of the control display screen needs to be adjusted due to different installation methods of electric water heaters, thereby overcoming the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] An adaptive electric water heater includes a shell, an inner tank, an electric heater, and a control system. The control system includes a power board and a control main board. The control main board is characterized by having an adaptive display screen and an adaptive switch. The adaptive display screen has a matrix display window, and the adaptive switch has a gravity sensor.

[0006] The gravity sensor provides a signal to the chip on the control motherboard, which then sends a drive signal to selectively drive either the horizontal dot matrix display circuit or the vertical matrix display circuit.

[0007] The gravity sensor includes a ball bearing and a photoelectric switch. The ball bearing is located inside the ball bearing cavity. The photoelectric detection channel passes through two coaxial detection ports in the ball bearing cavity. The photoelectric switch is connected to the chip of the control motherboard. When the housing is switched between horizontal and vertical orientation, the ball bearing triggers the photoelectric switch, causing the photoelectric switch to output a high or low level.

[0008] When the housing is upright, the photoelectric switch outputs a high level; when the housing is placed horizontally, the photoelectric switch outputs a low level.

[0009] The above technical solution has the following beneficial effects:

[0010] This invention utilizes a matrix display window on an adaptive display screen with two different display circuits for horizontal and vertical text, ensuring that the display screen presents text or icons that are visually pleasing regardless of whether the electric water heater is installed horizontally or vertically. This improves the user experience. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] See Figures 1-6 As shown, this utility model discloses an adaptive electric water heater, including a shell 1, an inner tank (not shown), an electric heater (not shown), and a control system. One end of the shell 1 is provided with an operation display area 2, which is approximately rectangular, having a long side and a short side, as shown below. Figure 1As shown, when the water heater is laid horizontally, the operation display area 2 is located on the left side of the casing and is in an upright position. Figure 2 As shown, when the electric water heater is placed vertically, the operation display area 2 is horizontally positioned at the bottom of the outer casing 1. The control system includes a power board (not shown) and a control main board 3 installed in the operation display area 2. The control main board 3 is equipped with an adaptive display screen 31 and an adaptive switch 32. The adaptive display screen 31 has a matrix display window 311, and the adaptive switch 32 has a gravity sensor 321. The gravity sensor 321 provides a signal to the chip on the control main board, which then issues a drive signal to selectively drive either the horizontal dot matrix display circuit or the vertical matrix display circuit. The power board supplies power to the control main board 3.

[0021] See Figure 1-2 When the electric water heater is installed horizontally, the gravity sensor inside the adaptive switch automatically connects to the horizontal dot matrix display circuit of the adaptive display screen, at which time the adaptive display screen 31 displays horizontal text or icons. When the electric water heater is installed vertically, it automatically connects to the vertical matrix display circuit of the adaptive display screen, at which time the text or icons displayed on the adaptive display screen 31 rotate with the display screen.

[0022] The gravity sensor 321 includes a ball bearing cavity 101, a ball bearing 103, a photoelectric switch, and a photoelectric detection channel 102. The photoelectric switch is communicatively connected to the chip on the control motherboard. When the photoelectric detection channel 102 is unobstructed, the photoelectric switch detects the photoelectric signal transmitted by the photoelectric detection channel, thereby generating a switching signal. The ball bearing is located inside the ball bearing cavity, which is elliptical in shape. Two coaxial detection ports are provided at both ends of the long axis. The photoelectric detection channel 102 passes through the two coaxial detection ports of the ball bearing cavity. The photoelectric switch can be the BL-1250-45-P photoelectric switch from Dongguan Bailing Electronics Co., Ltd., such as... Figure 5-6 As shown, when the water heater is placed vertically, the long axis of the ball bearing cavity is in a vertical state. Due to its own weight, the ball rolls to the detection port at the bottom of the ball bearing cavity, blocking the detection port and isolating the photoelectric detection channel. The photoelectric switch outputs a high level. When the water heater is placed horizontally, the ball is at the bottom short axis end of the ball bearing cavity, the photoelectric detection channel is unobstructed, and the photoelectric switch outputs a low level. The two placement methods send different signals to the chip on the control board, thereby allowing the display screen to display the display appropriate for the current installation orientation.

[0023] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
