As shown in fig. 1 to 3, an electric water heater with a tilt detection function includes: the electric water heater comprises an electric water heater body, wherein the electric water heater body comprises a circuit board and an operation panel connected with the circuit board, and is characterized in that a sensor for detecting whether the electric water heater inclines or not is arranged on the electric water heater body, the sensor is in communication connection with the circuit board of the electric water heater body, the circuit board is connected with an early warning device, and when the electric water heater body inclines, the circuit board generates an early warning signal to the early warning device.
The sensor is used for detecting an inclination angle value, the circuit board receives the inclination angle value of the sensor in an electric signal mode and compares the inclination angle value with a preset limit value theta, and if the inclination angle value is larger than the preset limit value theta, the circuit board sends an early warning signal to the early warning device. The sensor detects the inclination angle value of the electric water heater body, the sensor sends the inclination angle value to a circuit board of the electric water heater body in an electric signal mode, an MCU of the circuit board processes information in a centralized mode, the MCU compares the actually measured inclination angle value with a preset limit value theta according to a preset algorithm, and if the actually measured inclination angle value is smaller than the preset limit value theta, normal work is continued and the next detection and comparison are waited. If the actually measured inclination angle value is larger than the preset limit value theta, the inclination exceeding the allowable range of the whole machine is represented, the circuit board sends an early warning signal to inform a user of paying attention to safely avoid approaching the installation area of the electric water heater, and the emptying of the water in the inner container is timely reported.
In this embodiment, the sensor is a tilt sensor; in other embodiments, the sensor is a gyroscope, or is one or a combination of a tilt sensor, a gyroscope, a displacement sensor and a vibration sensor, and is not limited to the embodiment. When the mounting frame and the expansion bolt on the wall or the mounting frame and the whole machine inner container are loosened relatively and moved, the whole machine inner container, the mounting frame, the operation panel and the circuit board can generate certain vibration and displacement, and whether the mounted electric water heater body inclines or not can be judged in an auxiliary mode through detection of the vibration and the displacement.
In this embodiment, the sensor is fixed on a circuit board of the electric water heater body, and is fixedly mounted on a control panel of the electric water heater body together with the circuit board; the sensor is connected and communicated with a circuit board of the electric water heater body through a connecting wire. In other embodiments, the sensor may be fixed on the outer shell of the electric water heater body or any position of the electric water heater body as long as the sensor and the electric water heater body are fixed to each other, and the sensor and the circuit board of the electric water heater body are connected through a connecting wire or in wireless communication. Therefore, the sensor can be maintained more conveniently, and the circuit board of the electric water heater body is not required to be replaced or disassembled when the sensor is replaced. The inner container, the mounting rack, the operation panel and the circuit board of the water storage type electric water heater are mutually fixed. When the installation frame and the expansion bolt on the wall or the installation frame and the whole machine inner container are loosened relatively and moved, the whole machine inner container, the installation frame, the operation panel and the circuit board all can incline to a certain degree, so that the direct welding of the sensor on the circuit board has the advantages of optimal cost and simplest installation mode.
The operation panel comprises operation keys and a display screen; the inclination angle value is displayed in the display screen, and an early warning display module is arranged on the display screen.
The early warning signal is used for informing a user that the electric water heater inclines beyond the allowable range, and paying attention to safely avoid approaching the installation area of the electric water heater. The circuit board is connected with an early warning device, and when the circuit board judges that the inclination angle value is larger than a preset limit value theta, the circuit board controls the early warning device to give an alarm. The early warning device is a display screen of the electric water heater or an additional acousto-optic warning device. In other embodiments, a network communication module is disposed on the circuit board; the network communication module can adopt a wireless network communication module or a wired network communication module, the wireless network communication module can be networked through family WiFi, and the wired network communication module needs to be inserted with a network cable for networking. On the basis that the existing electric water heater is provided with a network communication module, the circuit board is connected with a mobile terminal through the network communication module, the mobile terminal is provided with a fault display module, and when the circuit board judges that the inclination angle value is larger than a preset limit value theta, a reminding message is sent to the mobile terminal.
The water outlet valve of the water heater body is an electric valve, the circuit board is connected with the water outlet valve of the electric water heater body, and when the electric water heater body inclines, the water outlet valve is opened to empty the liner water of the electric water heater body.
Further preferably, the sensor can also assist in detecting whether defects such as improper installation, inclined installation and the like exist on the installation circuit board and the operation panel during production of the electric water heater. If the defects exist, the defects are detected only by electrifying in the production line electric detection process, and if the inclination angle value detected by the inclination angle sensor is larger than theta, the mounting defects are represented, and careful inspection is needed to prevent defective products from flowing into the market.
Considering the problem of energy consumption, the tilt angle sensor adopts a working mode of electrifying the user every time and detecting once every hour, thereby better meeting the actual use requirements of the user.
As shown in fig. 1, the tilt sensor is directly mounted on the circuit board, and is fixedly mounted on the operation panel of the electric water heater together with the circuit board. Because the operation panel is mutually fixed with the electric water heater, when the whole machine inclines or displaces, the whole machine, the operation panel, the circuit board and the inclination angle sensor incline to a certain degree. When tilting occurs, a force F is generated, which causes an acceleration in the direction of the force F. Therefore, the inclination angle sensor can sense the generation of an acceleration, namely, the inclination of the whole machine is represented, and the inclination angle sensor sends a signal to the MCU to remind a user of overhauling.
As shown in fig. 3, the operation panels of different types of electric water heaters have certain differences, such as different scheduling and installation positions of curved surfaces. It is necessary to mount the circuit board with the tilt sensor on the final operation panel and set the initial value of the tilt sensor. And then, according to the actual volume and shape of the whole electric water heater, presetting the numerical value of the preset limit value theta of the inclination angle in the MCU. The preset limit value theta represents that after the inclination angle sensor actually detects the inclination angle value, the inclination angle sensor transmits an inclination angle signal to the MCU of the circuit board in real time, the MCU compares the actually-measured inclination angle with the preset limit value theta according to a preset algorithm, and if the actually-measured inclination angle value is smaller than the preset limit value theta, the MCU continues to normally work and waits for the next detection and comparison. If the actually measured inclination angle value is larger than the preset limit value theta, the inclination of the whole machine within the allowable range is represented, a user needs to be informed to safely avoid approaching the installation area of the electric water heater, and the water in the inner container is emptied and reported to be checked in time.
