Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioner controller technology, specifically a controller for wall-mounted air conditioners. Background Technology
[0002] In current usage, most air conditioners are controlled by users directly operating the buttons on the air conditioner or by operating an infrared remote control at close range. The human body senses the ambient temperature and humidity to regulate the operation of the air conditioner. However, sometimes the air conditioner temperature is set too low or too high, causing the air conditioner to run at high power for a long time.
[0003] For example, the socket-type controller for a split-type air conditioner disclosed in publication number "CN213366861U" receives input signals through a control module and controls the infrared receiving and transmitting module to emit infrared signals. These infrared signals control the operation of the air conditioner, thus achieving automatic control and energy saving. By incorporating an anti-electric shock module on the front panel, both the live and neutral wire sockets are blocked by the module's slider when the socket is not in use, preventing the risk of leakage due to user error. When a three-prong plug is inserted, the slider can only be driven by a grounded three-prong plug, further enhancing the device's safety.
[0004] The device achieves automatic power-off operation via a control module and infrared radiation. However, the control module generates heat during use, increasing the rate at which the internal temperature of the controller rises. Relying solely on the heat dissipation vents has limited effectiveness, especially since the outside temperature is often cold due to air conditioning, making heat dissipation even more difficult. Furthermore, the insertion process requires squeezing the limiting block to slide and rise, increasing the insertion force and affecting the efficiency of insertion and removal. Utility Model Content
[0005] The purpose of this utility model is to provide a dedicated controller for wall-mounted air conditioners. By using this device, the problems of existing control modules, such as increased internal temperature rise, difficulty in heat dissipation, and the need for a large force to insert a limit block to achieve the purpose of raising and lowering, are solved.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a controller for wall-mounted air conditioners, comprising a controller housing, a surface plate connected to the front side of the controller housing, a display panel connected to the center of the surface plate, an insertion port provided at the center of the controller housing, a sensing electrode connected to the inner side of the insertion port, a locking mechanism provided to the inner side of the sensing electrode, a circuit board provided to the inner side of the locking mechanism, a base plate provided to the inner side of the circuit board, a rubber block connected to the top inner surface of the controller housing, a control center connected below the rubber block, and a protective housing connected below the control center.
[0007] Preferably, the locking mechanism includes a locking block, an electromagnetic block, a magnetic block, a connecting rod, a limiting block, and a cleaning brush. The locking block has connecting rods symmetrically distributed on both sides. The two sides of the connecting rods are connected to the inner wall of the controller housing and are connected to the locking block through the connecting rods to ensure the locking block is fixed in place.
[0008] Preferably, the electromagnetic block and the magnetic block are magnetically attracted together, the magnetic block and the limiting block are integrally installed, and the limiting block and the locking block are connected by a sliding connection. The electromagnetic block attracts the magnetic block, thereby ensuring that the limiting block rises automatically.
[0009] Preferably, the size of the limiting block is the same as the size of the insertion port, and a cleaning brush is connected to the bottom center of the limiting block. The cleaning brush is composed of multiple small brushes. The limiting block drives the cleaning brush to rise, thereby automatically cleaning the insertion port and avoiding dust accumulation that could affect the detection sensitivity.
[0010] Preferably, the insertion port is a three-hole socket, and the internal array of the insertion port has sensing electrodes, which are copper foil electrodes. The insertion of the object is sensed by the sensing electrodes, thereby controlling the electromagnetic block to open and close automatically.
[0011] Preferably, an infrared transmitter is connected to the outer side of the circuit board, and a corresponding control module is connected to the inner side of the circuit board. Threaded grooves are provided on both sides of the circuit board. The infrared transmitter and the control module work together to automatically cut off the power.
[0012] Preferably, rubber blocks are symmetrically distributed on the upper part of the outer shell of the control center. The rubber blocks are integrally installed with the controller shell. The rubber blocks are shock-absorbing rubbers, which prevent the fan blades from making noise when rotating, thus affecting the use.
[0013] Preferably, the protective housing and the housing of the control center are installed as an integral unit. The inner side of the protective housing is connected to a miniature fan blade. The protective housing is inclined. The inclined protective housing and the miniature fan blade work together to accelerate the airflow between the inside and outside, thereby quickly dissipating heat and helping to blow away dust inside the insertion port.
[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: 1. High heat dissipation efficiency, avoiding dust accumulation in the insertion port and causing poor circuit contact: By setting inclined micro fan blades to accelerate the circulation of air inside and outside, the cool air from the outside air conditioner is brought into the inside of the controller housing for heat dissipation. The micro fan blades are aligned with the insertion port, allowing air to be exhausted from the insertion port outwards, preventing dust accumulation. 2. Automatic opening and closing, ensuring convenient socket insertion: By setting a sensing electrode at the insertion port, the inserted item is detected. When the electrode matches the socket, the electromagnetic block is energized to attract the magnetic block, causing the limit block to automatically rise, thereby releasing the limitation on the insertion port. Simultaneously, the rise and fall of the limit block drives the cleaning brush to move, thereby cleaning the inside of the insertion port and preventing dust from affecting the sensing electrode.

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.
[0018] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0019] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4A wall-mounted air conditioner controller includes a controller housing 1, a surface plate 3 connected to the front of the controller housing 1, a display panel 5 connected to the center of the surface plate 3, an insertion port 4 provided in the center of the controller housing 1, a sensing electrode 9 connected to the inside of the insertion port 4, a locking mechanism 2 provided inside the sensing electrode 9, a circuit board 6 provided inside the locking mechanism 2, a base plate 7 provided inside the circuit board 6, a rubber block 10 connected to the top inner surface of the controller housing 1, a control center 8 connected below the rubber block 10, and a protective housing 11 connected below the control center 8.
[0020] The present invention will be further described below with reference to the embodiments.
[0021] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The locking mechanism 2 includes a locking block 201, an electromagnetic block 202, a magnetic block 203, a connecting rod 204, a limiting block 205, and a cleaning brush 206. Connecting rods 204 are symmetrically distributed on both sides of the locking block 201. The two sides of the connecting rods 204 are connected to the inner wall of the controller housing 1, connecting the locking block 201 and ensuring its fixed operation. The electromagnetic block 202 and the magnetic block 203 have a magnetic attraction structure, and the magnetic block 203 and the limiting block 205 are integrally installed. The limiting block 205 and the locking block 201 are connected by a sliding connection. The electromagnetic block 202 attracts the magnetic block 203, thereby ensuring that the limiting block 205 rises automatically. The size of the limiting block 205 is the same as the size of the insertion port 4. A cleaning brush 206 is also connected to the bottom center of the limiting block 205. The cleaning brush 206 is composed of multiple small brushes. The limiting block 205 drives the cleaning brush 206 to rise, thereby automatically cleaning the insertion port 4 and preventing dust accumulation from affecting the detection sensitivity.
[0022] Please see Figure 1 , Figure 2 and Figure 4 The insertion port 4 is a three-hole socket. The internal array of the insertion port 4 contains sensing electrodes 9, which are copper foil electrodes. The sensing electrodes 9 sense the inserted object, thereby controlling the electromagnetic block 202 to open and close automatically. Rubber blocks 10 are symmetrically distributed on the top of the outer shell of the control center 8. The rubber blocks 10 are integrated with the controller outer shell 1. The rubber blocks 10 are shock-absorbing rubbers, which prevent noise from the fan blades when they rotate, thus avoiding affecting the use. The protective shell 11 is integrated with the outer shell of the control center 8. The inner side of the protective shell 11 is connected to a miniature fan blade. The protective shell 11 is tilted. The tilted protective shell 11 and the miniature fan blades work together to accelerate the airflow inside and outside, thereby quickly dissipating heat and helping to blow away the dust inside the insertion port 4.
[0023] Please see Figure 2 An infrared transmitter is connected to the outside of the circuit board 6, and a corresponding control module is connected to the inside of the circuit board 6. Threaded grooves are provided on both sides of the circuit board 6. The infrared transmitter and the control module work together to automatically cut off the power.
[0024] Working principle: First, during use, when the plug is moved to the insertion port 4, the plug first contacts the sensing electrode 9. The sensing electrode 9 senses the change in capacitance. The sensing electrode 9 is connected to the control center 8 via a capacitor chip, model FDC2214. The capacitance change sensed by the sensing electrode 9 is converted into a digital signal and transmitted to the control center 8. When the control center 8 recognizes the signal as a plug signal, it energizes the electromagnetic block 202, causing the electromagnetic block 202 to magnetically attract the magnetic block 203. At this time, the magnetic block 203 rises, thereby driving the limit block 205. The locking block 201 slides upward inside, at which point the limiting block 205 drives the cleaning brush 206 to rise, so that the cleaning brush 206 slides inside the insertion port 4 to clean the surface of the sensing electrode 9 and prevent dust accumulation. Then the plug is inserted into the circuit board 6 and power is turned on. After power is turned on and after a period of use, the control center 8 turns on the switch of the micro fan blade inside the protective shell 11, so that the micro fan blade drives the air circulation, so that the inside and outside air circulate, thereby allowing the outside cold air to enter the inside of the controller shell 1 and the hot air to be discharged.
[0025] It is worth noting that the infrared transmitter and its corresponding control module are disclosed in the socket-type controller of a split-type air conditioner, which is published under the publication number "CN213366861U".
