[0035] Figure 1FIG is a schematic structural diagram of a leakage protection system 100 according to an embodiment of the present invention. Figure 1 As shown, and reference Figures 2 to 5 An embodiment of the present invention provides a leakage protection system 100 for an air conditioner, including a leakage protector 110, which is disposed on a power cord 200 of the air conditioner to detect leakage current of the air conditioner and to disconnect the power cord 200 of the air conditioner. The leakage protector 110 is signal-connected to a controller 300 of the air conditioner, so that the controller 300 generates a warning message, a query message inquiring whether to disconnect the leakage protector 110, and a first execution message to disconnect the leakage protector 110 based on the leakage current obtained by the leakage protector 110, and transmits the first execution message to the leakage protector 110.

[0036] The leakage protector 110 can detect the leakage current of the air conditioner and be connected to the signal of the controller 300 of the air conditioner, so that the controller 300 of the air conditioner can generate a warning message to warn the user, or generate an inquiry message to ask the user whether to cut off the power. The leakage protector 110 can also receive the first execution information from the controller 300 to cut off the power, and cut off the power to the power cord 200 of the air conditioner according to the first execution information. Of course, the leakage protector 110 has multiple power-off modes. For example, when the leakage current is greater than the preset value, the leakage protector 110 can also actively cut off the circuit of the air conditioner. The above setting can cut off the power in time to avoid causing harm to the user when it detects that the air conditioner has a leakage, and at the same time can give the user more options. For example, if the leakage current is not large, you can choose not to cut off the power temporarily.

[0037] In other embodiments of the present invention, the controller 300 of the air conditioner generates first execution information for powering off the leakage protector 110 according to the leakage current obtained by the leakage protector 110 , and sends the first execution information to the leakage protector 110 .

[0038] In other embodiments of the present invention, the controller 300 of the air conditioner generates a warning message and an inquiry message for whether to power off the leakage protector 110 according to the leakage current obtained by the leakage protector 110 .

[0039] In some embodiments of the present invention, Figure 1As shown, the leakage protection system 100 also includes a reminder device 120, which is connected to the controller 300 of the air conditioner by signal to receive warning information and issue reminders. When a leakage occurs, the controller 300 of the air conditioner generates a warning message based on the leakage current of the leakage protector 110 and transmits it to the reminder device 120, which then issues a reminder to remind the user of the leakage. In some embodiments, the reminder issued by the reminder device 120 can be a warning sound, or an image or flashing light, etc. The provision of the reminder device 120 facilitates the interaction of information between the leakage protection system 100 of the air conditioner and the user, making it easier for the user to know and pay attention to the leakage situation, thereby preventing the user from causing harm.

[0040] In other embodiments of the present invention, the reminder device 120 can also receive inquiry information. In the event of a power leakage, the air conditioner controller 300 generates an inquiry message based on the leakage current of the leakage protector 110 and transmits it to the reminder device 120. The reminder device 120 then sends an inquiry message to inquire whether the user should turn off the power.

[0041] In other embodiments of the present invention, the reminder device 120 may further send second execution information to the controller 300 to cause the leakage protector 110 to power off. The second execution information here may be power-off execution information to which the user responds after being reminded or inquired.

[0042] Furthermore, in some embodiments of the present invention, the reminder device 120 comprises a household appliance, which is connected to the air conditioner controller 300 via a local area network (LAN). This arrangement facilitates integrated home installation, which involves integrating home products from different brands to ensure a unified overall style and functionality after installation, while also taking into account product characteristics and user needs. The reminder device 120 comprises a household appliance, and the air conditioner and the household appliance can be connected via a LAN, achieving a seamless home experience. In particular, utilizing existing household appliances as the reminder device 120 eliminates the need for adding new electrical equipment, saving costs and achieving two goals at once.

[0043] In other embodiments of the present invention, the household appliance and the controller 300 of the air conditioner may also be connected via Bluetooth signals.

[0044] Furthermore, in some embodiments of the present invention, the household appliance is another air conditioner, a stereo, a television, a smart screen and a computer.

[0045] Furthermore, in some embodiments of the present invention, the household appliance is another air conditioner, a stereo, a television, and a smart screen. In other words, the other air conditioner, the stereo, the television, and the smart screen can all serve as the reminder device 120.

[0046] Furthermore, in some embodiments of the present invention, the household appliance is another air conditioner, a stereo, a television, and a computer. In other words, the other air conditioner, the stereo, the television, and the computer can all serve as the reminder device 120.

[0047] Of course, in other embodiments of the present invention, the reminder device 120 includes a terminal device, which is a mobile phone or a tablet. These terminals, especially mobile phones, can ensure that the reminder information can be obtained by the user in a timely manner, and then pay attention to the leakage problem or provide execution feedback in a timely manner.

[0048] In other embodiments of the present invention, the terminal device is a mobile phone and a tablet.

[0049] In other embodiments of the present invention, the terminal device is a monitoring device. This setting is more effective for some special application scenarios, such as factories, where there are dedicated personnel to observe the monitoring equipment.

[0050] Alternatively, in other embodiments of the present invention, the reminder device 120 includes a reminder device installed on the indoor unit of the air conditioner, and the reminder device is a display screen, a buzzer, and a voice reminder device of the indoor unit. In other words, the reminder device 120 is directly the display screen, the buzzer, and the voice reminder device of the indoor unit 10 of the air conditioner. In this way, when the user needs to operate the air-conditioned room, they can obtain the reminder information in time to avoid electric shock.

[0051] In other embodiments of the present invention, the reminder device may be just a display screen of the indoor unit of the air conditioner.

[0052] In other embodiments of the present invention, the reminder device may be just a buzzer of the indoor unit of the air conditioner.

[0053] In other embodiments of the present invention, the reminder device may be just a voice reminder device of the indoor unit of the air conditioner.

[0054] In some embodiments of the present invention, Figure 1 As shown, the leakage protector 110 includes a circuit board 111, a control unit 112 arranged on the circuit board 111, a leakage detection unit 113 for detecting leakage current, an execution unit 115 for power off, and a signal transmission unit 114 for signal connection, and the signal transmission unit 114 is connected to the controller 300 of the air conditioner by signal.

[0055] The circuit board 111 is connected to the power supply, the control unit 112 receives information and issues control instructions, the leakage detection unit 113 detects the magnitude of the leakage current, the execution unit 115 cuts off the connection between the air conditioner and the power supply according to the control instruction issued by the control unit 112, and the signal transmission unit 114 is connected to the air conditioner controller 300 signal so that the controller 300 issues a warning message or an inquiry message according to the signal transmitted by the signal transmission unit 114, or the signal transmission unit 114 receives the first execution information or the second execution information and transmits it to the control unit 112 to control the execution unit 115 to work.

[0056] Furthermore, in some embodiments of the present invention, Figure 2 As shown, the actuator 115 is a trip device, comprising a frame 1151, with a coil 1155 disposed on the outside of the frame 1151. An iron core 1152 fixedly connected to the frame 1151 is disposed at one end within the frame 1151. The frame 1151 also includes an iron plate 1153 and a push rod 1156 fixedly connected to the iron plate 1153. The push rod 1156 extends through the iron core 1152, and the iron core 1152 is located between the push-out end of the push rod 1156 and the iron plate 1153. The control unit 112 energizes the coil 1155 based on the leakage current or the first execution information or the second execution information obtained by the leakage detection unit 113.

[0057] When the control unit 112 receives the first execution information or the second execution information requiring power off, or the leakage detection unit 113 obtains a leakage current, the coil 1155 is energized, and current flows through the coil 1155. According to the principle of electromagnetic induction, a magnetic field is generated around the coil 1155. The skeleton 1151 is provided with an iron core 1152 connected to the skeleton 1151. The skeleton 1151 is also provided with an iron plate 1153 and a push rod 1156. The iron plate 1153 moves under the action of the magnetic field, which can generate a large force to drive the push end of the push rod 1156 to extend from the end of the iron core 1152 away from the iron plate 1153. This makes the push rod 1156 move with greater force, thereby improving the tripping ability of the release. At the same time, this release has a simple structure and a small size, making it easy to be installed in household appliances.

[0058] Furthermore, in some embodiments of the present invention, the trip unit further includes a magnetizing housing 1157 disposed outside the frame 1151. This housing is spaced apart from the frame 1151 to form a mounting space between the housing 1157 and the frame 1151, within which the coil 1155 is located. The magnetizing housing 1157 exhibits a certain degree of magnetism, which increases the strength of the magnetic field, forming a stronger magnetic field. This allows the ejector 1156 to actuate with greater force, further enhancing the tripping capability of the trip unit.

[0059] In some embodiments of the present invention, an elastic member 1154 is provided between the iron core 1152 and the iron plate 1153, such as Figure 2 As shown, the elastic member 1154 is a compression spring. When the iron plate 1153 approaches the iron core 1152, the compression spring compresses and accumulates elastic potential energy. After the trip is completed, the compression spring releases the elastic potential energy and pushes the iron core 1152 back to its initial position. This arrangement can prevent the iron plate 1153 from failing to return to its initial position and affecting the second leakage tripping of the trip unit.

[0060] In some embodiments of the present invention, Figure 1 As shown, the leakage protection system 100 further includes a distribution box 130, which includes a main line 131, an air conditioning branch line 132, and a short-circuit protector 133. The air conditioning branch line 132 is connected to the main line 131. The short-circuit protector 133 is mounted on the main line 131 and is configured to de-energize the main line 131 and, in turn, the air conditioning branch line 132. The air conditioner power cord 200 is configured to be electrically connected to the air conditioning branch line 132.

[0061] The power cord 200 of the air conditioner is configured to be electrically connected to the air conditioning branch line 132. When a short circuit occurs, the short circuit protector 133 will work, cutting off the main line 131 and then cutting off the air conditioning branch line 132, so that the air conditioner is powered off to protect the safety of the user.

[0062] In some embodiments of the present invention, short-circuit protector 133 is an air switch. An air switch is a switch that automatically disconnects if the current in a circuit exceeds the rated current. It uses the flow of gas to open and close a circuit and typically consists of a control gas source, a piston, and contacts. An air switch can protect circuits or electrical equipment from short circuits, severe overloads, and undervoltages. It can also be used to infrequently activate air conditioners.

[0063] In some embodiments of the present invention, the short circuit protector 133 has pins for inserting into a socket.

[0064] In some embodiments of the present invention, the leakage protector 110 and the short-circuit protector 133 work simultaneously to ensure the safety of the user when a leakage occurs.

[0065] like Figure 3 As shown, during daily power on and off, when the air switch and the leakage protector 110 are powered on, the air conditioner works normally. When either the air switch or the leakage protector 110 is not powered, the air conditioner is powered off.

[0066] like Figure 4As shown, the air conditioner operates normally. When leakage occurs, the leakage protector 110 cuts off the power line 200 of the air conditioner for power-off protection, or when the air switch detects a short circuit, the air switch cuts off the power line 200 of the air conditioner for power-off protection.

[0067] Furthermore, in some embodiments of the present invention, Figure 5 As shown, the air conditioner is operating normally. When a leakage occurs, the leakage protector 110 detects whether the leakage current exceeds a first preset value. If so, the air conditioner controller 300 receives the leakage signal and issues a voice prompt, while also using a mobile phone app to push leakage information, alerting the user to a slight leakage. Furthermore, the leakage protector 110 detects whether the leakage current exceeds a second preset value. If so, the air conditioner controller 300 continues to issue a voice prompt, indicating that the leakage current has increased and reached the leakage standard, advising against approaching. It also recommends performing a power-off check and pushes a message via voice and a mobile phone app asking the user whether to perform a power-off. If the user responds with a request to perform a power-off, the system automatically performs a power-off protection. If the user responds with a request to continue testing the current, the leakage protector 110 continues to detect whether the current continues to increase until it reaches a third preset value. When the current continues to increase to the third preset value, the air conditioner controller 300 intelligently pushes the leakage information to the after-sales service center and controls the landing point protector to perform a power-off protection. Of course, when the leakage protector 110 does not detect leakage or does not perform power-off protection, but the short-circuit protector 133 detects a short circuit, the short-circuit protector 133 can implement active power-off protection.

[0068] In some embodiments of the present invention, the third preset value is greater than the second preset value, and the second preset value is greater than the first preset value. Preselected, the third preset value is 25mA, the second preset value is 10mA, and the first preset value is 5mA. The general safety current for the human body is 10mA, that is, when the leakage current is below 10mA, the leakage current is safe for the human body. Below 10mA, the controller 300 of the air conditioner sends a leakage warning signal to alert the user to the leakage and the user can choose whether to take measures. As the leakage current increases, when the leakage current reaches 25mA or more, it is difficult for the human body to get rid of the leakage electrical appliance. Especially when the leakage current reaches 50mA, the human body is in danger of life and may cause cardiac arrest and respiratory paralysis.

[0069] The present utility model also provides an air conditioner indoor unit 10, such as Figure 6 As shown, it includes an indoor unit and a leakage protection system 100 according to any of the above embodiments. The indoor unit has a power line 200 and a controller 300, and a leakage protector 110 is arranged on the power line 200. The leakage protector 110 is connected to the controller 300 for signal communication.

[0070] The leakage protector 110 can detect the leakage current of the air conditioner and be connected to the signal of the controller 300 of the air conditioner, so that the controller 300 of the air conditioner can generate a warning message to warn the user, or generate an inquiry message to ask the user whether to cut off the power. The leakage protector 110 can also receive the first execution information from the controller 300 to cut off the power, and cut off the power to the power cord 200 of the air conditioner according to the first execution information. Of course, the leakage protector 110 has multiple power-off modes. For example, when the leakage current is greater than the preset value, the leakage protector 110 can also actively cut off the connection of the power cord 200 of the air conditioner. The above setting can cut off the power in time to avoid causing harm to the user when the air conditioner detects a leakage. At the same time, it can give the user more options. For example, if the leakage current is not large, you can choose not to cut off the power temporarily.

The wall-mounted indoor unit includes a wall-mounted indoor unit housing and a laterally extending air outlet provided on the wall-mounted indoor unit housing. The wall-mounted indoor unit housing includes a laterally extending air duct, which is equipped with a laterally mounted crossflow fan and a heat exchanger. The outlet of the air duct serves as the air outlet. The floor-standing indoor unit includes a wall-mounted indoor unit housing and a vertically extending air outlet provided on the wall-mounted indoor unit housing. The wall-mounted indoor unit housing includes a vertically extending air duct, which is equipped with a vertically mounted crossflow fan and a heat exchanger. The outlet of the air duct serves as the air outlet.
