[0020] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the description.

[0021] like Figures 1 to 3 As shown, the present invention discloses an air conditioner, including a fan 10 and a germicidal lamp 30. The fan 10 is arranged in the heat exchange air duct 20 of the air conditioner; the germicidal lamp 30 is arranged in the heat exchange air duct 20, and the irradiation range of the germicidal lamp 30 covers the air outlet of the fan 10. The germicidal lamp 30 is used to sterilize the air outlet of the fan 10. When the air conditioner of the present invention is in use, the germicidal lamp can be turned on, and the ultraviolet rays of the germicidal lamp are irradiated on the air outlet of the fan. Since the irradiation range of the germicidal lamp covers the air outlet of the fan, the air outlet of the fan will be sterilized by ultraviolet rays, thereby achieving the purpose of sterilization. The air conditioner of the present invention can achieve the purpose of sterilizing and disinfecting the air by arranging the germicidal lamp in the heat exchange air duct, fully covering the air outlet position, and improving the sterilization effect.

[0022] It should be noted that since the irradiation range of the germicidal lamp covers the air outlet of the fan, the ultraviolet light can irradiate the inside of the fan. That is to say, not only the air outlet of the fan can be disinfected, but also the inside of the fan and the air inside the fan can be disinfected. Moreover, the irradiation can be carried out while the air is still inside the fan until the air passes through the germicidal lamp. The long irradiation time can improve the sterilization effect.

[0023] Furthermore, the germicidal lamp 30 is detachably disposed in the heat exchange air duct 20. By detachably disposing the germicidal lamp in the heat exchange air duct, the germicidal lamp can be disassembled during maintenance, which is convenient for cleaning and maintenance.

[0024] In existing air conditioners, such as ducted air conditioners, condensed water often forms on the evaporator during the cooling process, which can easily breed bacteria on the surface of the evaporator over time. Although the above scheme can sterilize the air outlet of the fan, the sterilized air will still be contaminated after passing through the bacterial evaporator. Therefore, it is not enough to simply sterilize the air.

[0025] In order to solve the above problems, the air conditioner further includes a heat exchanger 40, which is arranged in the heat exchange air duct 20, and the irradiation range of the germicidal lamp 30 also covers the heat exchanger 40. When in use, the irradiation range of the germicidal lamp can cover the air outlet of the fan and the heat exchanger at the same time, so that not only the outlet air can be sterilized and disinfected, but also the heat exchanger can be sterilized and disinfected, so that the fan outlet air will not be contaminated again by the heat exchanger, which completely improves the air quality and enhances the sterilization effect.

[0026] Furthermore, the germicidal lamp 30 includes a first germicidal lamp 30a and a second germicidal lamp 30b, wherein the first germicidal lamp 30a is arranged between the air outlet of the fan 10 and the heat exchanger 40, and in front of the first germicidal lamp and the air outlet of the fan. The second germicidal lamp 30b is arranged above the heat exchanger 40, and the irradiation range of the second germicidal lamp 30b also covers the airflow path between the air outlet of the fan 10 and the heat exchanger 40. When in use, the first germicidal lamp is arranged in front of the air outlet of the fan, so the ultraviolet light can be irradiated deeply into the interior of the fan volute, and the interior of the volute can be effectively sterilized and disinfected. At the same time, the first germicidal lamp can also irradiate the heat exchanger to sterilize and disinfect the heat exchanger; the second germicidal lamp is arranged above the heat exchanger. Since the heat exchanger is usually arranged at an angle, the second germicidal lamp is arranged above the heat exchanger. The irradiation range of the second germicidal lamp can be increased, and the area from the air outlet to the heat exchanger and the surface of the heat exchanger can be completely covered, thereby cooperating with the first germicidal lamp to form a secondary sterilization and disinfection, which can effectively eliminate bacteria and viruses in the air and greatly improve the air quality.

[0027] Furthermore, the germicidal lamp 30 includes a bracket 31, a mounting block 32 and a lamp tube 33. The bracket 31 is connected to the inner wall of the heat exchange duct 20; the mounting block 32 is detachably arranged on the bracket 31, there are at least two mounting blocks 32, all the mounting blocks 32 are arranged at intervals, and an installation space is formed between two adjacent mounting blocks 32; the lamp tube 33 is arranged in the installation space, and the two ends of the lamp tube 33 are respectively inserted into the corresponding mounting blocks 32.

[0028] When in use, install both ends of the bracket on the inner wall of the heat exchange duct. The bracket and the heat exchange duct can be detachably connected by bolts to facilitate subsequent maintenance, or they can be welded, which is more firm and reliable. The two ends of the lamp tube are respectively inserted into the mounting blocks, and then the mounting blocks are installed on the bracket by bolts, so that the lamp tube is fixed on the bracket, which is convenient for installation and disassembly.

[0029] It should be noted that, usually, multiple volutes are arranged inside the duct air conditioner, the number of lamp tubes can match the number of volutes, multiple lamp tubes are arranged at intervals on the bracket, and the positions of the lamp tubes correspond one by one to the positions of the air outlets of the volutes, so that the air outlet of each volute can be sterilized.

[0030] Furthermore, the irradiation range of the lamp tube 33 is at least 90°, and the bracket 31 is a hollow structure that allows light to pass through. The irradiation range of the lamp tube can be selected between 90° and 360°. If the irradiation range is too small, the air outlet of the fan and the heat exchanger cannot be covered at the same time. Therefore, the irradiation range of the lamp tube is at least 90°. Preferably, the irradiation range of the lamp tube is 270°, which can avoid the waste or leakage of excess ultraviolet lines and ensure that the air outlet and heat exchanger of the fan are fully covered. The design of the building control structure on the bracket can prevent the ultraviolet light from being blocked and improve the sterilization and disinfection effect.

[0031] like Figure 4 As shown, according to a second aspect of the present invention, a control method is disclosed for controlling the above-mentioned air conditioner, the air conditioner also includes a control device, the control device can be used to control the germicidal lamp 30, and the control method includes the following steps:

[0032] Step S10: Obtaining the ambient particle concentration R1 and the preset particle concentration R2;

[0033] Step S20: Controlling the operation mode of the germicidal lamp 30 according to the ambient particle concentration R1 and the preset particle concentration R2.

[0034] It should be noted that there are many ways for the control device to obtain the ambient particle concentration R1. The most basic way is to obtain it from the air quality detection device set in the air conditioner itself. With the development of the Internet of Things and intelligence, the control device also has various ways to obtain the ambient particle concentration R1, such as directly obtaining the ambient air quality through the network, or communicating with indoor air purifiers and other products through the Internet of Things to obtain the air detection data of the air purifier, etc. The connection between the control device and the germicidal lamp can be electrically connected by wires or wirelessly connected.

[0035] Furthermore, step S20 further includes the following steps:

[0036] When R1≥R2, the control device controls the germicidal lamp 30 to turn on;

[0037] When R1<R2, the control device controls the germicidal lamp 30 to be turned off.

[0038] Further, the air conditioner further includes: a heat exchanger 40, the heat exchanger 40 is arranged in the heat exchange air duct 20, and the irradiation range of the germicidal lamp 30 also covers the heat exchanger 40 at the same time; the germicidal lamp 30 includes: a first germicidal lamp 30a and a second germicidal lamp 30b, the first germicidal lamp 30a is arranged between the air outlet of the fan 10 and the heat exchanger 40, the second germicidal lamp 30b is arranged above the heat exchanger 40, and the irradiation range of the second germicidal lamp 30b also covers the air flow path between the air outlet of the fan 10 and the heat exchanger 40, and step S20 further includes the following steps:

[0039] Obtaining a preset particle concentration R3, and controlling the operation modes of the first germicidal lamp 30a and the second germicidal lamp 30b according to the ambient particle concentration R1, the preset particle concentration R2, and the preset particle concentration R3;

[0040] When R3>R1>R2, the control device controls the first germicidal lamp 30a to turn on and the second germicidal lamp 30b to turn off;

[0041] When R1>R3, the control device controls the first germicidal lamp 30a and the second germicidal lamp 30b to be turned on at the same time.

[0042] The control method of the present invention can be adjusted according to the specific conditions of indoor air by installing the first germicidal lamp 30a and the second germicidal lamp 30b, and whether the first germicidal lamp 30a and the second germicidal lamp 30b are in operation or not is determined according to the air quality, thereby achieving the purpose of automatic control and energy saving.

[0043] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here.
