Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioner indoor unit. Background Art

[0002] As people pay more attention to indoor air quality, the market demand for health is growing. Air conditioners are household appliances that are frequently used in daily life. They can provide cool air in summer and heating in winter. They are used more and more frequently. However, due to the lack of daily maintenance and cleaning, air conditioners cannot sterilize and breed microorganisms, which can easily cause air-conditioning diseases and skin diseases.

[0003] Air conditioner sterilization technology has received widespread attention. Pulse sterilization uses a pulse of strong white light to flash the inert gas lamp to emit ultraviolet to infrared light that is similar to the solar spectrum but more intense, thereby killing microorganisms on the surface. Existing pulse sterilization air conditioners usually include a separately set sterilization lamp module and a pulse electronic control module, in which the sterilization lamp module is fixedly installed in the evaporator, middle frame or air inlet to sterilize the air that has passed through the heat exchange and the inside of the evaporator. Since the sterilization lamp module is fixed in position, it cannot cover the entire evaporator, resulting in incomplete sterilization and poor user experience.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The problem solved by the present invention is that the position of the sterilization module in the existing air conditioner is not adjustable, and the small coverage area is prone to dead corners, resulting in incomplete sterilization.

[0006] To solve the above problems, the present invention provides an air-conditioning indoor unit, including an air inlet, a fan, and an evaporator. The air inhaled from the air inlet is driven by the fan and then blown out after heat exchange through the evaporator. The air-conditioning indoor unit also includes a pulse sterilization component, and the pulse sterilization component includes a first driving device and a pulse ultraviolet light module. The first driving device is located on the outside of the evaporator and is used to drive the pulse ultraviolet light module to reciprocate on a vertical plane.

[0007] This setting can make full use of the internal space of the air-conditioning indoor unit, can sterilize the evaporator and its upper and lower sides, and the generated pulse wave or light has a wide coverage range, which can thoroughly sterilize the interior of the air conditioner; the entire pulse sterilization component is located on the front side of the evaporator, will not interfere with the flow of the heat exchange airflow, has a reasonable structure, and provides a good user experience. Preferably, the first drive device is arranged in the middle position of the evaporator and can be fixedly assembled on the bottom shell and / or the middle frame. At this time, the pulse ultraviolet light module has the widest sterilization coverage range, and at the same time, the first drive device can support the air-conditioning indoor unit, so that the air-conditioning as a whole has good mechanical strength and occupies little space.

[0008] Preferably, the first driving device includes a first guide rail, a transmission member, and a motor. The first guide rail is arc-shaped and meshingly connected to the transmission member. One side of the transmission member is drive-connected to the motor, and the other side of the transmission member is connected to the pulsed ultraviolet light module.

[0009] This setting can drive the pulsed ultraviolet light module to move along the periphery of the evaporator, and continuously adjust the relative position of the pulsed ultraviolet light module and the evaporator during the sterilization process to make the sterilization inside the evaporator more thorough; setting the first guide rail in an arc shape can make full use of the internal space of the air-conditioning indoor unit, so that the pulsed ultraviolet light module is always close to the evaporator, with good sterilization effect and small wind resistance to the air-conditioning indoor unit.

[0010] Preferably, the first guide rail is provided with teeth, the teeth are arranged along the length direction of the first guide rail, and are used to mesh with the transmission member. A limiting groove is provided on the side away from the teeth, and the motor slides into the limiting groove. This arrangement enables the motor to move synchronously with the pulsed ultraviolet light module in the vertical plane, and the transmission is stable, reliable and easy to implement. Preferably, the limiting groove is located on the side of the teeth away from the support shaft.

[0011] Preferably, the first driving device also includes a connecting plate, a second guide rail, and a support shaft. The connecting plate is arranged along the length direction of the evaporator, and the two ends of the connecting plate are respectively slidably assembled with the first guide rail and the second guide rail, and the support shaft is respectively meshed and connected with the first guide rail and the second guide rail, and the pulsed ultraviolet light module is arranged on the support shaft. This arrangement can make the two ends of the support shaft bear the force evenly, and the transmission is stable and reliable with a long service life. Preferably, the first guide rail and the second guide rail are located at the two ends of the evaporator and are fixedly assembled with the evaporator bracket or the middle frame or the side end cover, and the connecting plate is arranged close to the air inlet. This arrangement can make full use of the internal space of the air conditioner, and at the same time, the overall strength of the air conditioner indoor unit can be strengthened through the first driving device; the structure is symmetrical and the appearance is beautiful.

[0012] Preferably, the pulse sterilization component also includes a second driving device, which includes a magnetic body and an electromagnet. The magnetic body is arranged on one of the pulse ultraviolet light module or the first driving device, and the electromagnet is arranged on the other of the pulse ultraviolet light module or the first driving device. The electromagnet cooperates with the magnetic body to drive the pulse ultraviolet light module to reciprocate along the support shaft.

[0013] This setting generates magnetic force by energizing the electromagnet to drive the pulsed ultraviolet light module to move by adsorbing the magnetic body. The magnetic force can be changed by adjusting the current, thereby controlling the movement speed. This setting has a simple structure and is easy to control. It can achieve surface coverage of the periphery of the evaporator and has a better sterilization effect. Preferably, the magnetic body is arranged on the pulsed ultraviolet light module, and the electromagnet is slidably arranged at the end of the support shaft.

[0014] Preferably, the second driving device further comprises a spring, which is sleeved on the support shaft and one end of which is connected to the pulsed ultraviolet light module. This arrangement allows the pulsed ultraviolet light module to be subjected to magnetic and elastic forces when moving horizontally, and the movement is smooth and easy to control; the first driving device and the second driving device can be operated simultaneously or separately to achieve full coverage in the two-dimensional space of pulse sterilization.

[0015] Preferably, the first driving device and the second driving device are operated separately, so that the pulsed ultraviolet light module first moves on the vertical plane to a position close to the air outlet, and then moves in the horizontal direction through the second driving device. At this time, there is enough space inside the air conditioner indoor unit that will not interfere with the movement of the pulsed ultraviolet light module.

[0016] Preferably, the pulsed ultraviolet light module includes a lamp holder, a sealing plug, a bracket, and a germicidal lamp. The bracket is arranged on the lamp holder near the evaporator, the germicidal lamp is arranged between the lamp holder and the bracket, and sealing plugs are arranged at both ends of the germicidal lamp. This arrangement can take into account both the tightness and convenience of assembly, and facilitates the installation and replacement of the germicidal lamp.

[0017] Preferably, a mounting plate is provided on the side of the lamp holder away from the bracket, the mounting plate is provided with a through hole, a bearing is provided in the through hole, and the bearing sleeve is provided on the outer peripheral side of the support shaft. This arrangement enables the lamp holder to be slidably mounted on the support shaft with low movement resistance; it can ensure that the pulsed ultraviolet light module is always vertically downward under the action of gravity, has low resistance to the heat exchange airflow, is not easy to form condensed water on its surface, and has a high safety factor.

[0018] Preferably, the side of the bracket close to the lamp holder is inwardly recessed to form an installation cavity for accommodating the germicidal lamp, and a third notch is provided on the side of the bracket away from the lamp holder, and the third notch is connected to the installation cavity. This arrangement can ensure that the pulse light waves generated by the germicidal lamp are directed toward the evaporator side, and will not directly irradiate components such as the panel and cause them to age.

[0019] Preferably, the pulsed ultraviolet light module further includes a light-transmitting plate, which can block the third gap. This arrangement places the germicidal lamp in a relatively closed environment, and its operating reliability will not be affected by air quality; the cold energy carried by the evaporator can be used to dissipate heat and cool the germicidal lamp, which is conducive to the continuous operation of the germicidal lamp and further improves the sterilization effect; even if condensed water is generated on the surface of the light-transmitting plate, it will not affect the normal operation of the germicidal lamp, and the safety factor is high.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be noted that the technical features in each embodiment of the present invention can be combined with each other.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] Unless otherwise clearly stipulated and limited, the first feature being "above" or "below" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. The first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is higher in level than the second feature.

The up, down, left, right and other directional definitions in the present invention are the directions recognized when facing the front panel of the air conditioner after the air conditioner is normally installed.

[0034] Indoor air quality is closely related to human health. If there are carriers of respiratory viruses in a poorly ventilated room, there may be a risk of cross-infection, especially in winter when influenza is most prevalent. In order to ensure the heating effect, doors and windows are usually closed for a long time to allow the indoor air to circulate repeatedly, further increasing the probability of cross-infection among people.

[0035] With the advancement of science and technology, people pay more and more attention to their own health, and many indoor air conditioners have added purification modules. However, the common HEPA net and positive and negative ion purification can only adsorb but not completely kill the bacteria in the air, so pulse sterilization air conditioners came into being. Because the pulse ultraviolet light module 21 is usually fixed in position and it is difficult to cover the entire evaporator 1, it does not completely sterilize the inside of the air conditioner indoor unit. After the sterilization is completed, the microorganisms will multiply rapidly and affect the user experience. For this reason, the applicant proposes the following technical solution:

[0036] like Figure 1-4 An air conditioner indoor unit includes an air inlet, a fan 3, and an evaporator 1. The air inhaled from the air inlet is driven by the fan 3 and blown out after heat exchange through the evaporator 1. The air conditioner indoor unit also includes a pulse sterilization component 2. The pulse sterilization component 2 includes a connected first driving device 23 and a pulse ultraviolet light module 21. The first driving device 23 is located on the outside of the evaporator 1 and is used to drive the pulse ultraviolet light module 21 to move on a vertical plane.

[0037] This setting can make full use of the internal space of the air-conditioning indoor unit, and can sterilize the evaporator 1 and its upper and lower sides. The generated pulse wave or light has a wide coverage range; the entire pulse sterilization component 2 is located on the front side of the evaporator 1 and will not interfere with the flow of the heat exchange airflow. It has a reasonable structure and a good user experience.

[0038] The air conditioner indoor unit also includes a panel 5 and an air guide plate 4. The panel 5 is located in front of the evaporator 1. The air guide plate 4 is arranged on the lower side of the panel 5. The specific structure and assembly relationship of the panel 5 and the air guide plate 4 are all prior art and will not be described in detail here. Preferably, the first drive device 23 is located between the panel 5 and the evaporator 1 and is arranged close to the air inlet.

The first guide rail 231 is arc-shaped and meshes with the transmission member 232. One side of the transmission member 232 is drive-connected to the motor 233, and the other side of the transmission member 232 is connected to the pulse ultraviolet light module 21. The structure of the arrangement is simple, and the pulse ultraviolet light module 21 can be driven by the motor 233 to move vertically along the periphery of the evaporator 1; the relative position of the pulse ultraviolet light module 21 and the evaporator 1 can be continuously adjusted during the sterilization process to make the sterilization inside the evaporator 1 more thorough; the first guide rail 231 is arranged in an arc shape to make full use of the internal space of the air conditioner indoor unit, so that the pulse ultraviolet light module 21 is always close to the evaporator 1, the sterilization effect is good, and the wind resistance to the air conditioner indoor unit is small.

[0040] The pulse sterilization component 2 also includes a pulse electric control module 22, which is electrically connected to the pulse ultraviolet light module 21; the pulse electric control module 22 is arranged at the middle frame or the end of the evaporator 1, which can make full use of the internal space of the indoor unit of the air conditioner and has a compact structure.

The supporting shaft 235 is respectively meshed and connected with the first guide rail 231 and the second guide rail 236.

[0042] The connecting plate 237 can be located at the end or the middle of the first guide rail 231. This arrangement allows the first guide rail 231 and the second guide rail 236 to form a whole, which is convenient for installation; at the same time, the connecting plate 237 can also be connected to the middle frame to improve the assembly tightness of the first driving device 23.

The electromagnet 242 is arranged on the other of the pulse ultraviolet light module 21 or the first driving device 23. The electromagnet 242 acts with the magnetic body 2113 to drive the pulse ultraviolet light module 21 to slide along the support shaft 235. This setting generates a magnetic force after the electromagnet 242 is energized to drive the pulse ultraviolet light module 21 to move by adsorbing the magnetic body 2113. The magnetic force can be changed by adjusting the current, thereby controlling the movement speed. This setting has a simple structure and is easy to control. It can achieve surface coverage of the periphery of the evaporator 1, and has a better sterilization effect.

[0044] Preferably, the magnetic body 2113 is disposed on the pulsed ultraviolet light module 21, and the electromagnet 242 is disposed at the end of the support shaft 235, close to the first guide rail 231 or the second guide rail 236.

This arrangement is that the motor 233 is located outside the first guide rail 231, which is convenient for installation and maintenance.

[0047] Preferably, the second drive device 24 also includes a spring 241, which is sleeved on the support shaft 235 and has one end respectively connected to the pulse ultraviolet light module 21, and the other end fixedly connected to the first mounting plate 234 or the second mounting plate 238. This arrangement allows the pulse ultraviolet light module 21 to be subjected to magnetic and elastic forces when moving horizontally, and the movement is smooth and easy to control; the first drive device 23 and the second drive device 24 can act simultaneously or separately. Preferably, the lengths of the spring 241 and the support shaft 235 are A1 and A2, respectively, where A2=2*A1. This arrangement allows the pulse ultraviolet light module 21 to be in the middle position of the evaporator 1 after the spring 241 is reset, and the resistance when moving to both sides is the same, which is easy to control.

[0048] As an example of the present invention, the first driving device 23 further includes a second mounting plate 238, the second mounting plate 238 is located on the side of the second guide rail 236 away from the support shaft 235, a second limit block 2381 is provided on one side of the first mounting plate 234, the second limit block 2381 is slidably assembled to the second guide rail 236, and an electromagnet 242 is provided on the second mounting plate 238. The structure of the arrangement is simple, and the transmission is stable and reliable. It should be noted that the electromagnet 242 and the motor 233 are electrically connected to the complete electronic control module of the air conditioner indoor unit.

[0049] like Figure 5-8 As shown, the pulsed ultraviolet light module 21 includes a lamp holder 211, a sealing plug 212, a bracket 213, and a germicidal lamp 214.

A bearing is provided in the through hole 2112, and the bearing sleeve is provided on the outer peripheral side of the support shaft 235. This arrangement has a simple structure and small sliding resistance. The side wall of the lamp holder 211 is provided with a first notch 2115, a second notch 2116, and a first card slot 2114, and the first notch 2115 and the second notch 2116 are respectively located on the left and right sides of the first card slot 2114. This arrangement facilitates the deformation of the side wall where the first card slot 2114 is located, and facilitates the disassembly and assembly of the bracket 213. Preferably, the sizes of the first notch 2115 and the second notch 2116 may be the same or different.

[0051] As an example of the present invention, the side of the bracket 213 close to the lamp holder 211 is recessed inward to form an installation cavity 2131 for accommodating the germicidal lamp 214.

This arrangement can limit the assembly of the germicidal lamp 214 through the cooperation of the bracket 213 and the lamp holder 211, and has a simple structure and is easy to disassemble and assemble.

[0052] Preferably, the pulsed ultraviolet light module 21 further includes a light-transmitting plate 215, which can block the third notch 2132. This arrangement has a simple structure and does not affect the sterilization effect of the pulsed light; at the same time, it prevents the condensed water generated by the evaporator 1 from contacting the sterilization lamp 214, thereby affecting the safety of use.

[0053] As an example of the present invention, a first buckle 2133 is provided on the outer side of the bracket 213, and a first slot 2114 is provided on the lamp holder 211 at a position corresponding to the first buckle 2133, and the first buckle 2133 can be limitedly assembled in the first slot 2114.
