Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to an indoor unit for an air conditioner. Background Technology

[0002] With people paying increasing attention to indoor air quality, the market demand for health products is growing stronger. Air conditioners, as frequently used household appliances, are ubiquitous due to their ability to provide cool air in summer and heating in winter. However, due to inadequate daily maintenance and cleaning, air conditioners not only fail to kill bacteria but also easily cause air conditioning sickness, skin diseases, and other ailments due to the growth of microorganisms.

[0003] Air conditioner sterilization technology has received widespread attention. Pulse sterilization, in particular, utilizes intense pulsed white light to cause inert gas lamps to emit ultraviolet to infrared light, similar in intensity to the solar spectrum but much stronger, to kill microorganisms on surfaces. Existing pulse sterilization air conditioners typically include a separate sterilization lamp module and a pulse control module. The sterilization lamp module is fixedly mounted on the evaporator, middle frame, or air inlet to sterilize the air after heat exchange and the interior of the evaporator. Because the sterilization lamp module is fixed in position, it cannot cover the entire evaporator, resulting in incomplete sterilization and a poor user experience.

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

[0005] The problem solved by this invention is that the position of the sterilization module in existing air conditioners is not adjustable, which can easily lead to blind spots due to the small coverage area, resulting in incomplete sterilization.

[0006] To address the aforementioned problems, the present invention provides an indoor air conditioning unit, comprising an air inlet, a fan, and an evaporator. Air drawn in from the air inlet is blown out after heat exchange in the evaporator under the drive of the fan. The indoor air conditioning unit further comprises a pulse sterilization component, which includes a first driving device and a pulse ultraviolet light module. The first driving device is located outside the evaporator and is used to drive the pulse ultraviolet light module to reciprocate in a vertical plane.

[0007] This design fully utilizes the internal space of the air conditioner's indoor unit, sterilizing the evaporator and its upper and lower sides. The generated pulse waves or light have a wide coverage area, thoroughly sterilizing the air conditioner's interior. The entire pulse sterilization component is located on the front side of the evaporator, avoiding interference with the heat exchange airflow. Its rational structure and superior user experience are advantages. Preferably, the first drive device is positioned in the middle of the evaporator and can be fixedly mounted on the bottom shell and / or middle frame. In this configuration, the pulsed ultraviolet light module achieves the widest sterilization coverage, while the first drive device provides support for the indoor unit, resulting in excellent mechanical strength and a small footprint.

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

[0009] This setup allows the pulsed ultraviolet light module to move along the periphery of the evaporator, continuously adjusting the relative position of the pulsed ultraviolet light module and the evaporator during the sterilization process to ensure more thorough sterilization inside the evaporator. Setting the first guide rail in an arc shape fully utilizes the internal space of the air conditioner's indoor unit, ensuring that the pulsed ultraviolet light module remains close to the evaporator, resulting in good sterilization effect and low air resistance to the air conditioner's indoor unit.

[0010] Preferably, the first guide rail is provided with teeth arranged along its length for meshing with the transmission component. A limiting groove is provided on the side of the teeth away from the transmission component, and the motor sliding device slides into the limiting groove. This arrangement allows the motor to move synchronously with the pulsed ultraviolet light module in the vertical plane, ensuring stable and reliable transmission and facilitating implementation. Preferably, the limiting groove is located on the side of the teeth away from the support shaft.

[0011] Preferably, the first driving device further includes a connecting plate, a second guide rail, and a support shaft. The connecting plate is arranged along the length of the evaporator, and its two ends are slidably assembled with the first guide rail and the second guide rail, respectively. The support shaft is engaged with the first guide rail and the second guide rail, respectively, and the pulsed ultraviolet light module is mounted on the support shaft. This arrangement ensures uniform force distribution at both ends of the support shaft, resulting in stable and reliable transmission and a long service life. Preferably, the first guide rail and the second guide rail are located at both ends of the evaporator and are fixedly assembled with the evaporator bracket, middle frame, or side end cover, etc., and the connecting plate is located near the air inlet. This arrangement makes full use of the internal space of the air conditioner, and at the same time, the first driving device can enhance the overall strength of the indoor unit of the air conditioner; the structure is symmetrical and the appearance is aesthetically pleasing.

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

[0013] This setup utilizes the magnetic force generated by energizing an electromagnet to attract a magnetic object, thereby driving the pulsed ultraviolet light module. The magnetic force can be adjusted by changing the current, thus controlling the movement speed. This setup is simple in structure, easy to control, and can achieve complete surface coverage of the evaporator, resulting in superior sterilization. Preferably, the magnetic object is located on the pulsed ultraviolet light module, and the electromagnet is slidably positioned at the end of the support shaft.

[0014] Preferably, the second driving device further includes a spring, which is sleeved on the support shaft and one end 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, resulting in smooth and easy-to-control movement. The first and second driving devices can operate simultaneously or separately to achieve full coverage of the two-dimensional space for pulsed sterilization.

[0015] Preferably, the first driving device and the second driving device operate respectively, causing the pulsed ultraviolet light module to first move in the vertical plane to a position close to the air outlet, and then move in the horizontal direction through the second driving device. At this time, there is enough space inside the air conditioner indoor unit to avoid interfering with the movement of the pulsed ultraviolet light module.

[0016] Preferably, the pulsed ultraviolet light module includes a lamp holder, sealing plugs, a bracket, and a germicidal lamp. The bracket is positioned on the side of the lamp holder closest to the evaporator, and the germicidal lamp is positioned between the lamp holder and the bracket. Sealing plugs are provided at both ends of the germicidal lamp. This design balances assembly tightness and convenience, facilitating the installation and replacement of the germicidal lamp.

[0017] Preferably, an assembly plate is provided on the side of the lamp holder away from the bracket. The assembly plate has a through hole, and a bearing is installed in the through hole. The bearing is sleeved on the outer periphery of the support shaft. This arrangement allows the lamp holder to slide on the support shaft with low movement resistance; it ensures that the pulsed ultraviolet light module is always vertically downward under the action of gravity, resulting in low resistance to heat exchange airflow and less condensation on its surface, thus ensuring a high safety factor.

[0018] Preferably, the bracket has an inwardly recessed mounting cavity on the side near the lamp holder to accommodate the germicidal lamp, and a third notch is provided on the side of the bracket away from the lamp holder, the third notch communicating with the mounting cavity. This arrangement ensures that the pulsed light waves generated by the germicidal lamp are directed towards the evaporator side, and do not directly irradiate components such as the panel, causing them to age.

[0019] Preferably, the pulsed ultraviolet light module further includes a light-transmitting plate that can block the third gap. This arrangement keeps the germicidal lamp in a relatively enclosed environment, and its operational reliability is not affected by air quality; the cooling capacity carried by the evaporator can dissipate heat from the germicidal lamp, which is beneficial for continuous operation of the germicidal lamp and further improves the sterilization effect; even if condensation occurs on the surface of the light-transmitting plate, it will not affect the normal operation of the germicidal lamp, resulting in a high safety factor.

[0020] Compared with the prior art, the air conditioner indoor unit of the present invention has the following beneficial effects: 1) The pulsed ultraviolet light module can move around the periphery of the evaporator in different directions, which can sterilize the evaporator and its upper and lower components, and the radiation range is wide; 2) The internal space of the air conditioner indoor unit can be fully utilized, and the existing structure needs little modification; the transmission is stable and reliable through meshing transmission and electromagnetic drive; 3) The structure is simple and easy to manufacture and process.

Detailed Implementation

[0031] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the technical features in the various embodiments 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 construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] Unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that they are in indirect contact through an intermediate medium. "Above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "below" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature. The directional definitions of up, down, left, and right in this invention refer to the orientation perceived when facing the front panel of the air conditioner after normal installation.

[0034] Indoor air quality is closely related to human health. If there are respiratory virus carriers in poorly ventilated indoor spaces, there may be a risk of cross-infection, especially during the winter flu season. In order to ensure heating efficiency, doors and windows are usually closed for a long time, causing indoor air to circulate repeatedly, which further increases the probability of cross-infection among people.

[0035] With the advancement of technology, people are paying more and more attention to their health, and many indoor air conditioners have added purification modules. However, common HEPA filters and positive and negative ion purification can only adsorb but not completely kill bacteria in the air. Therefore, pulse sterilization air conditioners have emerged. Because the pulse ultraviolet light module 21 is usually fixed in position and cannot cover the entire evaporator 1, its sterilization of the indoor unit is incomplete. After sterilization, microorganisms multiply rapidly, affecting the user experience. Therefore, the applicant proposes the following technical solution:

[0036] like Figure 1-4 An indoor air conditioning unit includes an air inlet, a fan 3, and an evaporator 1. Air drawn in from the air inlet is blown out after heat exchange in the evaporator 1 under the drive of the fan 3. The indoor air conditioning unit also includes a pulse sterilization component 2, which includes a first driving device 23 and a pulse ultraviolet light module 21 connected to each other. The first driving device 23 is located outside the evaporator 1 and is used to drive the pulse ultraviolet light module 21 to move in a vertical plane.

[0037] This setup makes full use of the internal space of the air conditioner's indoor unit, and can sterilize the evaporator 1 and its upper and lower sides. The generated pulse waves or light have 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 heat exchange air. The structure is reasonable and provides a good user experience.

[0038] The indoor unit of the air conditioner also includes a panel 5 and an air guide plate 4. The panel 5 is located on the front side of the evaporator 1, and 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 existing technologies and will not be described in detail here. Preferably, the first driving device 23 is located between the panel 5 and the evaporator 1 and is arranged close to the air inlet.

[0039] As an example of the present invention, the first driving device 23 includes a first guide rail 231 and a transmission component 232. The first guide rail 231 is arc-shaped and meshes with the transmission component 232. One side of the transmission component 232 is driven by a motor 233, and the other side of the transmission component 232 is connected to the pulsed ultraviolet light module 21. This configuration is simple in structure. The motor 233 can drive the pulsed ultraviolet light module 21 to move vertically along the periphery of the evaporator 1. It can continuously adjust the relative position of the pulsed ultraviolet light module 21 and the evaporator 1 during the sterilization process to make the sterilization inside the evaporator 1 more thorough. Setting the first guide rail 231 in an arc shape can make full use of the internal space of the air conditioner indoor unit, so that the pulsed ultraviolet light module 21 is always close to the evaporator 1, resulting in good sterilization effect and low wind resistance to the air conditioner indoor unit.

[0040] The pulse sterilization component 2 also includes a pulse electronic control module 22, which is electrically connected to the pulse ultraviolet light module 21. The pulse electronic control module 22 is located at the end of the middle frame or the evaporator 1, which makes full use of the internal space of the air conditioner indoor unit and results in a compact structure. The specific structure of the pulse electronic control module 22 is prior art and will not be described in detail here.

[0041] Preferably, the first driving device 23 further includes a connecting plate 237 and a second guide rail 236. The connecting plate 237 is arranged along the length of the evaporator 1, and the first guide rail 231 and the second guide rail 236 are respectively arranged at both ends of the connecting plate 237. The first guide rail 231 is arranged perpendicular to the connecting plate 237. The first driving device 23 also includes a support shaft 235, which is meshed with the first guide rail 231 and the second guide rail 236 respectively. The pulsed ultraviolet light module 21 is arranged on the support shaft 235. This arrangement has a simple structure and stable and reliable transmission.

[0042] The connecting plate 237 can be located at the end or 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, facilitating 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 drive device 23. The first guide rail 231 and the second guide rail 236 can be assembled onto the middle frame or the evaporator bracket.

[0043] Preferably, the pulse sterilization component 2 further includes a second driving device 24, which includes a magnetic body 2113 and an electromagnet 242. The pulse ultraviolet light module 21 is slidably mounted on the support shaft 235. The magnetic body 2113 is mounted on either the pulse ultraviolet light module 21 or the first driving device 23, and the electromagnet 242 is mounted on the other. The electromagnet 242 drives the pulse ultraviolet light module 21 to slide along the support shaft 235 by interacting with the magnetic body 2113. This arrangement generates a magnetic force by energizing the electromagnet 242, which attracts the magnetic body 2113 to drive the pulse ultraviolet light module 21 to move. The magnetic force can be changed by adjusting the current, thereby controlling the movement speed. This arrangement has a simple structure, is easy to control, and can achieve surface coverage of the evaporator 1, resulting in 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, near the first guide rail 231 or the second guide rail 236. The magnetic body 2113 can be disposed at any position on the pulsed ultraviolet light module 21, such as the end or side.

[0045] As an example of the present invention, the first guide rail 231 is provided with teeth 2312, which are arranged along the length of the first guide rail 231 for meshing with the transmission component 232. A limiting groove 2311 is provided on the side of the teeth 2312 away from the support shaft 235, and the motor 233 slides into the limiting groove 2311. This arrangement has a simple structure, stable and reliable transmission, and occupies little space, making it easy to implement.

[0046] As an example of the present invention, the first driving device 23 further includes a first mounting plate 234, which is located on the side of the first guide rail 231 away from the support shaft 235. A motor 233 and a first limiting block 2341 are mounted on the first mounting plate 234. The first limiting block 2341 and the sliding device are positioned within the limiting groove 2311. The motor 233 is driven by the transmission component 232. This arrangement positions the motor 233 outside the first guide rail 231, facilitating installation and maintenance.

[0047] Preferably, the second driving device 24 further includes a spring 241, which is sleeved on the support shaft 235 and has one end fixedly connected to the pulsed 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 pulsed ultraviolet light module 21 to be subjected to magnetic and elastic forces when moving horizontally, resulting in smooth movement and easy control. The first driving device 23 and the second driving device 24 can operate 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 ensures that the pulsed ultraviolet light module 21, after the spring 241 is reset, is in the middle position of the evaporator 1, and the resistance is the same when moving to both sides, facilitating control.

[0048] As an example of the present invention, the first driving device 23 further includes a second mounting plate 238, which is located on the side of the second guide rail 236 away from the support shaft 235. A second limiting block 2381 is provided on one side of the first mounting plate 234, and the second limiting block 2381 is slidably assembled to the second guide rail 236. An electromagnet 242 is provided on the second mounting plate 238. This configuration has a simple structure and stable and reliable transmission. It should be noted that the electromagnet 242 and the motor 233 are electrically connected to the overall 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. The bracket 213 is set on the side of the lamp holder 211 near the evaporator 1. The germicidal lamp 214 is set between the lamp holder 211 and the bracket 213. Sealing plugs 212 are set at both ends of the germicidal lamp 214. The germicidal lamp 214 is electrically connected to the pulsed electronic control module 22. This configuration is simple and facilitates the assembly and disassembly of the germicidal lamp 214.

[0050] As an example of the present invention, an assembly plate 2111 is provided on the side of the lamp holder 211 away from the bracket 213. The assembly plate 2111 has a through hole 2112, and a bearing is installed in the through hole 2112. The bearing is sleeved on the outer periphery of the support shaft 235. This arrangement has a simple structure and low sliding resistance. The side wall of the lamp holder 211 has a first notch 2115, a second notch 2116, and a first slot 2114. The first notch 2115 and the second notch 2116 are located on the left and right sides of the first slot 2114, respectively. This arrangement facilitates the deformation of the side wall where the first slot 2114 is located under stress and facilitates the assembly and disassembly of the bracket 213. Preferably, the dimensions of the first notch 2115 and the second notch 2116 can be the same or different.

[0051] As an example of the present invention, the bracket 213 is recessed inward on the side near the lamp holder 211 to form a mounting cavity 2131 for accommodating the germicidal lamp 214. A third notch 2132 is provided on the side of the bracket 213 away from the lamp holder 211, and the third notch 2132 communicates with the mounting cavity 2131 to allow pulsed light to pass through. This arrangement, through the cooperation of the bracket 213 and the lamp holder 211, enables the germicidal lamp 214 to be positioned and assembled, resulting in a simple structure that is easy to assemble and disassemble.

[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 avoids the condensate generated by the evaporator 1 from contacting the germicidal 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 corresponding position to the first buckle 2133. The first buckle 2133 can be limited and fitted into the first slot 2114. This arrangement ensures that force applied from the outside of the lamp holder 211 acts on the first buckle 2133, facilitating the quick removal of the bracket 213 from the lamp holder 211; at the same time, the first buckle 2133 fills the fitting groove, making the side wall of the lamp holder 211 flat and improving the overall aesthetics. Preferably, there are four first buckles 2133 symmetrically arranged on the left and right sides of the bracket 213. The structure is simple and aesthetically pleasing.

[0054] Preferably, a fourth notch 2134 is provided at one end of the bracket 213, and the fourth notch 2134 communicates with the mounting cavity 2131. This arrangement has a simple structure and facilitates wiring. Preferably, the germicidal lamp 214 can be a xenon lamp or an ultraviolet lamp; preferably, the germicidal lamp 214 is a xenon lamp, which outputs a high-level pulse of 5ms every 1s, requiring an excitation time of 2 seconds, for a total of 120 pulses. The pulse frequency can be adjusted according to the number of bacteria, for example, by first being fast and then slowing down within each sterilization cycle.

[0055] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
