Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, and in particular to a wall-mounted household appliance with a sensor switch. Background Technology

[0002] Traditional wall-mounted household appliance switches mostly use button or knob control methods, which are relatively cumbersome to operate. In addition, users may find it inconvenient to operate the buttons or knobs due to wet hands, and there may even be certain safety hazards.

[0003] With the development of smart home appliances, there is an urgent need in the market for a more convenient and user-friendly control method to improve the user experience of wall-mounted appliances. Existing sensing control methods often use horizontally positioned signal transceivers, which have limitations in detection range and accuracy. These methods are not well-suited to the usage scenarios of wall-mounted appliances and struggle to accurately detect hand movements below the appliance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wall-mounted household appliance with an induction switch, which can avoid the phenomenon that the signal transceiver device is difficult to accurately detect the user's hand signal located below the wall-mounted household appliance when the signal transceiver device is set horizontally. It can accurately detect the user's hand movements located below the wall-mounted household appliance, thereby realizing convenient and accurate on / off control of the wall-mounted household appliance, thus overcoming the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A wall-mounted household appliance with a sensor switch includes a locator and a PCB board. The PCB board is mounted on the appliance. The locator includes a first locator and a second locator, respectively mounted on opposite sides of the PCB board. Each locator includes a first mounting base and a second mounting base. The first mounting base has a downward-sloping hole for mounting a signal transmitting device, and the second mounting base has a downward-sloping slot for mounting a signal receiving device. A limiting block is provided within the slot. The signal transmitting and receiving devices are soldered onto the PCB board. The signal transmitting and receiving devices are used to send and receive signals downwards, respectively. When the signal transmitting device detects a user's hand movement below the appliance, the signal receiving device receives a feedback signal from the user's hand movement. The central processing unit on the PCB board outputs a power-on or power-off control command based on the order of the user's hand feedback signals received by the first and second locators, causing the wall-mounted appliance to turn on or off.

[0007] The wall-mounted household appliances include range hoods, electric water heaters, or air conditioners.

[0008] The locator is made of plastic and has a buckle at the bottom to fix it to the PCB board.

[0009] The connection between the first mounting base and the second mounting base forms a "V" shaped connection structure. An inclined plate is provided on the first mounting base near the connection point to avoid blocking signal reception.

[0010] The first mounting base has a receiving groove above the oblique hole for the signal transmitting device. Its size matches the shape of the signal transmitting device and is used for embedding and installing the signal transmitting device to stabilize the signal transmitting device.

[0011] The signal transmitting device is an infrared transmitter, and the signal receiving device is an infrared receiver, which are respectively installed in the oblique hole and the slot, so that they are tilted downwards to transmit and receive signals.

[0012] The above technical solution has the following beneficial effects:

[0013] This invention utilizes a unique locator design to enable the signal transceiver to send and receive signals at an angle downwards, accurately detecting hand gestures from users located below wall-mounted home appliances, thereby achieving convenient and accurate on / off control of wall-mounted home appliances.

[0023] 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.

[0024] See Figures 1-6 As shown, this utility model discloses a wall-mounted household appliance with a sensor switch. The wall-mounted household appliance with a sensor switch includes a locator and a PCB board 7. The PCB board 7 is mounted on the wall-mounted household appliance. The locator includes a first locator 8 and a second locator 9, respectively mounted on both sides of the PCB board 7. Each locator includes a first mounting base and a second mounting base. The first mounting base has a downward-sloping oblique hole 1 for mounting a signal transmitting device, and the second mounting base has a downward-sloping slot 2 for mounting a signal receiving device. A limiting block 3 is provided in the slot 2. The signal transmitting device and the signal receiving device are soldered onto the PCB board 7. The signal transmitting device and the signal receiving device are used to send and receive signals downwards, respectively. When the signal transmitting device detects a user's hand movement below the wall-mounted household appliance, the signal receiving device receives a feedback signal from the user's hand movement. The central processing unit on the PCB board 7 outputs a power-on or power-off control command based on the order of the user's hand feedback signals received by the first locator 8 and the second locator 9, causing the wall-mounted household appliance to turn on or off.

[0025] The wall-mounted household appliances include range hoods, electric water heaters, or air conditioners.

[0026] The positioner is made of plastic and has a buckle 4 at the bottom, which is used to fix it to the PCB board 7.

[0027] The connection between the first mounting base and the second mounting base forms a "V" shaped connection structure. An inclined plate 6 is provided on the first mounting base near the connection point. The inclined plate 6 is used to avoid blocking the reception of signals.

[0028] The first mounting base has a receiving groove 5 above the oblique hole 1 for the signal transmitting device. Its size matches the shape of the signal transmitting device and is used for embedding and installing the signal transmitting device to stabilize the signal transmitting device.

[0029] The signal transmitting device is an infrared transmitter, and the signal receiving device is an infrared receiver, which are respectively installed in the oblique hole 1 and the slot 2, so that they are tilted downwards to transmit and receive signals.

[0030] The working principle of this utility model:

[0031] The signal transmitting device on the locator sends signals at an angle downwards. Since the user is typically positioned below the wall-mounted appliance, the transmitting and receiving devices are used to send and receive signals at an angle downwards, respectively. When the transmitting signal detects hand movements by the user below the appliance, the receiving device receives the feedback signal. The central processing unit on PCB board 7 outputs a power-on or power-off control command based on the sequence of the user's hand feedback signals received by the first locator 8 and the second locator 9, causing the wall-mounted appliance to turn on or off. This slot 2 and angled hole 1 design changes the traditional horizontal signal transmission and reception mode of signal transceivers, making the signal detection direction more closely match the actual scenario of the user operating below the water heater, greatly improving the accuracy and reliability of the detection.

[0032] 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.
