[0040] The term "and / or" is a description of the association relationship between objects, which means that there can be three relationships. For example, A and / or B means that there are three relationships of A or B, or A and B.

[0041] It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0042] As shown in Figures 1 to 7 The embodiments of the present disclosure provide a purification device 20 for an air conditioner and an air conditioner, which can reduce the wind resistance of the catalyst plate 21 while ensuring the purification effect. In this way, the catalyst plate 21 can be avoided to affect the air flow rate in the air duct, and the user's use experience is improved.

[0043] As shown in Figures 1 to 7 The embodiments of the present disclosure provide a purification device 20 for an air conditioner, which includes a shell and a heat exchanger 11, the shell is provided with an air inlet, the heat exchanger 11 is arranged in the shell, and the purification device 20 includes a catalyst plate 21 and an ultraviolet lamp 23. The catalyst plate 21 is arranged between the air inlet and the heat exchanger 11, the catalyst plate 21 is configured in an arc shape, and the catalyst plate 21 is provided with a plurality of air vents 211 corresponding to the air inlet; the ultraviolet lamp 23 is arranged on one side of the catalyst plate 21, and the ultraviolet lamp 23 is configured to emit ultraviolet rays to the catalyst plate 21; wherein the inner side wall surface of the air vent 211 is arranged in a form perpendicular to the catalyst plate 21.

[0044] Specifically, the shell further comprises an air outlet, the air inlet and the air outlet are communicated through an air duct, and the air flow direction of the air duct is defined from the air inlet to the air outlet. The catalyst plate 21 is arranged in the air duct and located between the air inlet and the heat exchanger 11, so that the air flow passes through the catalyst plate 21 and the heat exchanger 11 in sequence. The catalyst plate 21 is provided with a plurality of air vents 211, and the plurality of air vents 211 are uniformly arranged on the catalyst plate 21, so that the air flow can pass through the catalyst plate 21 through the air vents 211 and flow to the heat exchanger 11. The catalyst plate 21 is coated with a photocatalyst, and the ultraviolet lamp 23 is fixedly installed on one side of the catalyst plate 21, and the ultraviolet lamp 23 can emit ultraviolet rays to the catalyst plate 21 to excite the photocatalyst on the catalyst plate 21.

[0045] When the user needs to purify the ambient air, the ultraviolet lamp 23 can be turned on. In this way, when the air flows from the air inlet of the shell into the air duct and flows to the catalyst plate 21, the ultraviolet lamp 23 excites the photocatalyst on the catalyst plate 21 to decompose volatile organic compounds in the air, thereby achieving the effect of purifying the air. The purified air flows to the heat exchanger 11 for heat exchange and then flows out of the shell through the air outlet, thereby improving the quality of the ambient air. As can be seen, since the catalyst plate 21 is configured as an arc-shaped plate structure, and the side walls of the air vents 211 on each part of the catalyst plate 21 are all arranged perpendicular to the catalyst plate 21, therefore, the air flowing to the catalyst plate 21 from all directions in the air duct will not be hindered by the side walls of the air vents 211 when passing through the air vents 211. In this way, the air resistance of the catalyst plate 21 can be reduced while ensuring the purification effect. In this way, the catalyst plate 21 can avoid affecting the air flow rate in the air duct, thereby improving the user's experience.

[0046] In actual application, the volatile organic compounds can be formaldehyde, benzene, toluene, etc. The above-mentioned volatile organic compounds can stimulate the eyes, respiratory tract and skin of human beings, and thus affect the health of human beings. These volatile organic compounds can come from the combustion products of bituminous coal, natural gas, etc., or the smoke generated by smoking, heating, cooking, etc., or the volatilization of building and decoration materials, furniture, household appliances, cleaning agents. Therefore, in the case of people's increasing demand for the quality of life, the treatment of these volatile organic compounds cannot be ignored.

[0047] As Figures 2 to 7As shown, the purification device 20 further comprises a mounting plate 22 fixedly mounted on the shell. The mounting plate 22 comprises a mounting frame 221 and a fixed plate body 222, the fixed plate body 222 is arranged at one edge of the mounting frame 221 and extends to one side of the mounting frame 221. The shape and size of the mounting frame 221 correspond to the catalyst plate 21, so that the catalyst plate 21 can be fixedly mounted on the mounting frame 221 by clamping members such as buckles or fasteners such as bolts. The ultraviolet lamp 23 is fixedly mounted on the fixed plate body 222, and the ultraviolet lamp 23 is located at the side of the fixed plate body 222 corresponding to the catalyst plate 21.

[0048] As shown in Figure 5 and Figure 6 In some embodiments, the air vent 211 is provided with a wind guide surface 212 on the side facing the air inlet, and the wind guide surface 212 is inclined to the direction away from the air vent 211 on the side facing the air inlet.

[0049] Specifically, the air vent 211 is provided with an inclined surface to form a wind guide surface 212 on the side facing the air inlet, and the wind guide surface 212 is inclined to the direction away from the air vent 211 on the side facing the air inlet. In this way, when the air flows from the air inlet to the catalyst plate 21, the wind guide surface 212 can guide the air to the middle of the air vent 211, so as to further avoid the influence of the catalyst plate 21 on the air flow rate in the air duct, and improve the user experience.

[0050] As shown in Figures 2 to 6 In some embodiments, the inner side wall surface of at least one air vent 211 is arranged in parallel to the air inlet direction of the air inlet.

[0051] Specifically, the catalyst plate 21 is arranged at least partially perpendicular to the air inlet direction of the air inlet, and at least one air vent 211 is arranged at this position. At this time, the side wall surface of the air vent 211 is parallel to the air inlet direction of the air inlet. Therefore, the air flow from the air inlet to the catalyst plate 21 can directly pass through the catalyst plate 21 from the above-mentioned air vent 211, so as to further reduce the influence of the catalyst plate 21 on the air flow.

[0052] As shown in Figures 2 to 7 In some embodiments, the two sides of the catalyst plate 21 are curved towards the heat exchanger 11; the ultraviolet lamp 23 is arranged between the catalyst plate 21 and the heat exchanger 11.

[0053] Specifically, after ambient air flows into the duct through the air inlet, the airflow may flow in multiple directions and reach the catalyst plate 21 from multiple directions. Therefore, the catalyst plate 21 is bent towards the heat exchanger 11 on both sides to form an arc-shaped plate structure, allowing the airflow flowing to the catalyst plate 21 from various directions to pass through the vent 211. At the same time, placing the ultraviolet lamp 23 between the catalyst plate 21 and the heat exchanger 11 can avoid areas on the catalyst plate 21 that are not illuminated by the ultraviolet lamp 23, and can also prevent the ultraviolet lamp 23 from blocking the airflow to the catalyst plate 21.

[0054] like Figure 3 As shown, in some embodiments, the position of the ultraviolet lamp 23 corresponds to the center of the catalyst plate 21.

[0055] Specifically, by positioning the ultraviolet lamp 23 in the middle of the catalyst plate 21, it is possible to ensure that the ultraviolet lamp 23 receives sufficient ultraviolet radiation to both the upper and lower halves of the catalyst plate 21, thereby ensuring that the photocatalyst in both the upper and lower halves of the catalyst plate 21 can be activated simultaneously.

[0056] like Figure 5 As shown, in some embodiments, the angle of bending of the two sides of the catalyst plate 21 is greater than or equal to a first preset angle and less than or equal to a second preset angle.

[0057] Specifically, the angle of curvature on both sides of the catalyst plate 21 is greater than or equal to 20° and less than or equal to 70°. For example, the angle of curvature on both sides of the catalyst plate 21 can be 20°, 30°, 40°, 50°, 60°, or 70°. It is understandable that if the angle of curvature on both sides of the catalyst plate 21 is less than 20°, the distance between the two sides of the catalyst plate 21 and the ultraviolet lamp 23 will be too large, which will prevent the ultraviolet lamp 23 from activating the photocatalyst on both sides of the catalyst plate 21; if the angle of curvature on both sides of the catalyst plate 21 is greater than 70°, the angle of curvature on both sides of the catalyst plate 21 will be too large, which will affect the airflow passing through the catalyst plate 21.

[0058] In some embodiments, the ultraviolet lamp 23 is configured as a UVC ultraviolet lamp 23.

[0059] Specifically, the UVC ultraviolet lamp 23 refers to an ultraviolet lamp 23 that emits ultraviolet rays with a wavelength of 200-275nm. When used in conjunction with a photocatalyst, the UVC ultraviolet lamp 23 can decompose volatile organic compounds in the air while simultaneously generating strong oxidants to kill bacteria and viruses, further enhancing the user experience.

[0060] like Figures 1 to 7As shown, the air conditioner provided by the embodiment of the present disclosure also includes a shell, a heat exchanger 11, and the purification device 20 for the air conditioner described above. The shell is provided with an air inlet; the heat exchanger 11 is arranged in the shell; and the purification device 20 for the air conditioner is arranged between the air inlet and the heat exchanger 11.

[0061] Specifically, the shell 10 also includes an air outlet, and the air outlet and the air inlet are communicated through an air duct, so that the air flowing from the air inlet can flow out from the air outlet. The heat exchanger 11 and the purification device 20 for the air conditioner are both arranged in the air duct, and the purification device 20 is located on the side of the heat exchanger 11 close to the air inlet.

[0062] The air conditioner provided by the purification device 20 for the air conditioner of the present application can reduce the wind resistance of the catalyst plate 21 while ensuring the purification effect. In this way, the catalyst plate 21 can avoid affecting the air flow rate in the air duct, thereby improving the user experience.

[0063] As shown in Figure 2 and Figure 3 In some embodiments, the purification device 20 for the air conditioner includes an ultraviolet lamp 23; and the air conditioner further includes a control device 31 and a concentration sensor 32. The control device 31 is electrically connected with the ultraviolet lamp 23, and is used to control the ultraviolet lamp 23 to be turned on or off; the concentration sensor 32 is used to obtain the concentration of volatile organic compounds in the environment, and the concentration sensor 32 is electrically connected with the control device 31 to send a concentration signal to the control device 31; wherein the control device 31 can control the ultraviolet lamp 23 to be turned on or off according to the concentration signal.

[0064] Specifically, the control device 31 includes a touch panel or a remote control device, etc., so that the user can input a concentration threshold signal to the controller of the control device 31. The controller is electrically connected with the ultraviolet lamp 23 to control the ultraviolet lamp 23 to be turned on or off. In the case that the ultraviolet lamp 23 is turned on, the control device 31 can also control the intensity of the ultraviolet lamp 23. The concentration sensor 32 can periodically obtain the concentration of volatile organic compounds in the environment and send a concentration signal to the control device 31.

[0065] When the concentration sensor 32 detects that the concentration of volatile organic compounds in the environment is greater than a first concentration threshold, the concentration sensor 32 sends a high concentration signal to the control device 31. After receiving the high concentration signal, the control device 31 controls the ultraviolet lamp 23 to turn on and controls the ultraviolet lamp 23 to be in a high intensity state to purify the ambient air. When the concentration sensor 32 detects that the concentration of volatile organic compounds in the environment is less than the first concentration threshold and greater than a second concentration threshold, the concentration sensor 32 sends a low concentration signal to the control device 31. After receiving the high concentration signal, the control device 31 controls the ultraviolet lamp 23 to turn on and controls the ultraviolet lamp 23 to be in a low intensity state. When the concentration sensor 32 detects that the concentration of volatile organic compounds in the environment is less than the second concentration threshold, the ultraviolet lamp 23 is controlled to be turned off. Wherein the first concentration threshold is greater than the second concentration threshold.

[0066] In some embodiments, the air conditioner further comprises a human body sensor. The human body sensor is used to obtain personnel information in the environment, and the human body sensor is electrically connected to the control device 31 to send the personnel information to the control device 31; wherein the control device 31 can control the ultraviolet lamp 23 to turn on or off according to the personnel information.

[0067] Specifically, the personnel information includes the number of personnel, and the control device 31 can control the ultraviolet lamp 23 to turn on or off according to the number of personnel.

[0068] Optionally, the air conditioner further comprises a fan, and the fan is arranged in the air duct. The control device 31 is further electrically connected to the fan to control the opening or closing of the fan. In the case that the fan is turned on, the control device 31 can further control the rotating speed of the fan.

[0069] In some practical applications, when the number of personnel is equal to 1, the control device 31 controls the ultraviolet lamp 23 to turn on, and controls the intensity of the ultraviolet lamp 23 to be 4000uw / cm 3 When the number of personnel is greater than or equal to 2 and less than or equal to 3, the control device 31 controls the intensity of the ultraviolet lamp 23 to be 4500uw / cm 3 When the number of personnel is greater than or equal to 4 and less than or equal to 5, the control device 31 controls the intensity of the ultraviolet lamp 23 to be 5000uw / cm 3 When the number of personnel is greater than or equal to 6, the control device 31 controls the intensity of the ultraviolet lamp 23 to be 5500uw / cm 3 At the same time, when the concentration of volatile organic compounds is less than 0.25mg / m 3 , the control device 31 controls the fan to be in a low wind speed state. When the concentration of volatile organic compounds is greater than or equal to 0.25mg / m 3 and less than or equal to 0.4mg / m 3At this time, control device 31 controls the fan to be in medium wind speed mode. When the concentration of volatile organic compounds is greater than 0.4 mg / m³... 3 At that time, the control device 31 controls the fan to be in a high wind speed state.

[0070] In other practical applications, control device 31 can also control the operating time of ultraviolet lamp 23 and fan. This is applicable when the concentration of volatile organic compounds is less than 0.25 mg / m³. 3 During this period, control device 31 controls the ultraviolet lamp 23 and the fan to run for 1 hour. This is when the concentration of volatile organic compounds is greater than or equal to 0.25 mg / m³. 3 And less than or equal to 0.4 mg / m 3 During this period, control device 31 controls the ultraviolet lamp 23 and the fan to run for 1.5 hours. This is when the concentration of volatile organic compounds is greater than 0.4 mg / m³. 3 At that time, the control device 31 controls the ultraviolet lamp 23 and the fan to run for 2 hours.
