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 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, which is why pulse sterilization air conditioners have emerged.

[0003] Pulse sterilization utilizes intense flashes of white light to cause inert gas lamps to emit ultraviolet to infrared light, similar in intensity to the solar spectrum, thus killing microorganisms on surfaces. Existing pulse sterilization air conditioners typically include separate sterilization lamp modules and pulse control modules. To fully utilize the internal space of the indoor unit, these modules need to be installed in different locations and connected by wires. This setup requires separate assembly of the sterilization lamp module and pulse control module, involving long wiring, resulting in cumbersome assembly and low efficiency.

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

[0005] The problem solved by this invention is that existing sterilization devices are cumbersome to assemble and have poor operational stability.

[0006] To address the aforementioned problems, this invention provides an indoor air conditioning unit, comprising a fan and an evaporator. Air drawn in is blown out after heat exchange in the evaporator, driven by the fan. The indoor air conditioning unit also includes a pulse sterilization integrated module, comprising a sterilization lamp and an electronic control unit electrically connected to each other. The pulse light emitted by the sterilization lamp illuminates at least the evaporator. The sterilization lamp and the electronic control unit are fixedly assembled via a connecting part, with a horizontal distance between them less than 10 cm; or, the sterilization lamp and the electronic control unit are mounted on the same mounting base.

[0007] This setup allows the germicidal lamp unit and the electrical control unit to be assembled into a pulse sterilization integrated module, which can then be assembled into the air conditioner indoor unit. This simplifies wiring and increases assembly efficiency. At the same time, the connection between the germicidal lamp unit and the electrical control unit is stable and reliable. It makes full use of the existing structure, requires minimal modification to the middle frame, and facilitates disassembly, assembly, and maintenance.

[0008] Preferably, the indoor unit of the air conditioner further includes a middle frame, in which an evaporator is disposed, and the pulse sterilization integrated module is installed on the evaporator, or installed on the middle frame at a distance of less than 10mm from the evaporator.

[0009] This setup utilizes a pulse sterilization integrated module to disinfect the evaporator surface and also irradiates the air ducts for sterilization. If installed on the evaporator bracket or frame and suspended at the front of the evaporator, or mounted on the panel and positioned at the front of the evaporator when the panel is closed, the pulse sterilization integrated module, by being directly opposite the evaporator, can increase the coverage area of ​​the pulse light, resulting in better sterilization and minimal impact on the evaporator's air exchange rate when the sterilization function is not in use. This improves the indoor unit's efficiency and enhances user comfort. Furthermore, this setup fully utilizes the air conditioner's internal structure, is compact, requires minimal modification to the existing air conditioner structure, and is easy to implement.

[0010] Preferably, the germicidal lamp unit includes a first mounting base, and the electrical control unit includes a second mounting base. The first and second mounting bases are integrally formed and arranged sequentially along the length of the evaporator. This arrangement allows the germicidal lamp unit and the electrical control unit to be mounted on the same mounting base, achieving modularization and integration of the sterilization function, resulting in high assembly efficiency and stable and reliable connection.

[0011] Preferably, the germicidal lamp unit further includes a sealing plug, a bracket, and a germicidal lamp. The first mounting base is provided with the bracket on the side near the evaporator. The germicidal lamp is provided between the first mounting base and the bracket. Sealing plugs are provided at both ends of the germicidal lamp. The germicidal lamp is electrically connected to the electrical control unit.

[0012] This setup features a simple structure, stable and reliable connection, and convenient installation and replacement of the germicidal lamp. The germicidal lamp can be a xenon lamp or an ultraviolet lamp; preferably, it is a xenon lamp, outputting a high-level pulse of 5ms every 1 second, requiring a specific excitation time, for a total of 120 pulses. The pulse frequency can be adjusted according to the number of bacteria, for example, by starting fast and then slowing down within each sterilization cycle.

[0013] Preferably, the bracket has an inwardly recessed mounting cavity on the side closest to the first mounting base to accommodate the germicidal lamp, and a third notch is provided on the side of the bracket furthest from the first mounting base, the third notch communicating with the mounting cavity. This design is simple in structure, and the germicidal lamp can be positioned and assembled by the bracket in cooperation with the first mounting base. It is simple in structure and easy to assemble and disassemble.

[0014] Preferably, the germicidal lamp section further includes a light-transmitting plate for sealing the third gap. This arrangement is simple in structure and does not affect the germicidal effect of the pulsed light; at the same time, it prevents condensate from the evaporator from contacting the germicidal lamp, thus avoiding any impact on safety during use.

[0015] Preferably, a first buckle is provided on the outer side of the bracket, and a first slot is provided on the first mounting base at a corresponding position, allowing the first buckle to be fitted into the first slot. This arrangement ensures that force applied from the outside of the first mounting base is applied to the first buckle, facilitating quick removal of the bracket from the first mounting base; simultaneously, the first buckle filling the fitting slot ensures a smooth sidewall of the first mounting base, resulting in a high overall aesthetic appeal. Preferably, four first buckles are symmetrically arranged on the left and right sides of the bracket. The structure is simple and aesthetically pleasing.

[0016] Preferably, the first mounting base is provided with a first notch and a second notch, which are located on the left and right sides of the first slot, respectively. This arrangement facilitates the deformation of the side wall where the first slot is located under stress, and facilitates the assembly and disassembly of the bracket.

[0017] Preferably, a connecting portion is provided between the first mounting base and the second mounting base. The connecting portion is separately provided or integrally formed with the first mounting base and the second mounting base. The middle frame is provided with a vertical support column. The connecting portion is partially recessed to form a groove. The vertical support column can be limited and assembled into the groove.

[0018] This design increases the contact area between the pulse sterilization integrated module and the middle frame. At the same time, the vertical support column and the groove are used to limit the pulse sterilization integrated module, further improving the stability and efficiency of assembly. It also provides support for the middle position of the pulse sterilization integrated module to prevent it from bending and deforming.

[0019] Preferably, the electronic control unit further includes a cover, the opening of the first mounting base faces the evaporator, and the opening of the second mounting base faces away from the evaporator. The second mounting base is detachably connected to the cover. This arrangement prevents condensate from directly entering the second mounting base and affecting the operational safety of the electronic control unit; at the same time, the opening of the second mounting base faces the panel side, facilitating maintenance.

[0020] Compared with the prior art, the air conditioner indoor unit of the present invention has the following beneficial effects: 1) The assembly efficiency and connection stability of the sterilization module can be improved by integrating and modularizing the sterilization lamp part and the electrical control part; 2) The pulse sterilization integrated module can make full use of the internal space of the air conditioner indoor unit by assembling it onto the evaporator or the middle frame, with minimal modification to the existing structure and convenient production; 3) The assembly efficiency can be improved and the overall mechanical strength is good by integrating the first mounting base and the second mounting base.

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, without conflict, the technical features in the 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] Air conditioners regulate indoor temperature by exchanging heat with the air to provide a comfortable environment. Regular cleaning of the air conditioner's interior is necessary to remove microorganisms. A large proliferation of microorganisms inside can cause discomfort and even "air conditioner sickness." Therefore, air conditioners with sterilization functions have emerged, typically consisting of a separate sterilization lamp module and an electrical control box module that powers the lamp. However, this structure is flawed, leading to cumbersome and inefficient assembly. Therefore, the applicant proposes the following technical solution:

[0035] Example 1

[0036] like Figure 1-4 As shown, an indoor air conditioning unit includes an air inlet, a fan 10, 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 10. The indoor air conditioning unit also includes a pulse sterilization integrated module 2 mounted on the middle frame 9. The pulse sterilization integrated module 2 includes a sterilization lamp part 21 and an electronic control part 22 that are electrically connected to each other. The pulse light emitted by the sterilization lamp part 21 illuminates at least the evaporator 1. The sterilization lamp part 21 and the electronic control part 22 are fixedly assembled and the horizontal distance between them is less than 10cm, or the sterilization lamp part 21 and the electronic control part 22 are mounted on the same mounting base.

[0037] This configuration allows the germicidal lamp unit 21 and the electrical control unit 22 to be assembled into a pulse sterilization integrated module 2, which can then be assembled into the air conditioner indoor unit. This simplifies wiring and increases assembly efficiency. At the same time, the connection between the germicidal lamp unit 21 and the electrical control unit 22 is stable and reliable. It makes full use of the existing structure, requires minimal modification to the middle frame 9, and facilitates disassembly, assembly, and maintenance.

[0038] As an example of the present invention, the pulse sterilization integrated module 2 is installed on the middle frame 9 or at a distance of less than 10mm from the evaporator 1. Preferably, a vertical support column (not shown in the figure) is provided on the middle frame 9, and a connecting part 23 is provided between the sterilization lamp part 21 and the electrical control part 22, the connecting part 23 abutting against the vertical support column; the sterilization lamp part 21 is plugged into the middle frame 9, and the electrical control part 22 is screwed into the middle frame 9.

[0039] Preferably, the connecting portion 23 is recessed inward to form a groove 231, and the vertical support column can be positioned and fitted into the groove 231. This arrangement increases the contact area between the pulse sterilization integrated module 2 and the middle frame, and at the same time, the cooperation between the vertical support column and the groove 231 limits the position of the pulse sterilization integrated module 2, further improving the stability and efficiency of the assembly; it also provides support for the middle position of the pulse sterilization integrated module 2, preventing it from bending and deforming.

[0040] As an example of the present invention, the germicidal lamp unit 21 includes a first mounting base 211, and the electronic control unit 22 includes a second mounting base 221. The first mounting base 211 and the second mounting base 221 are integrally formed and arranged sequentially along the length direction of the evaporator 1, and the openings of the first mounting base 211 and the second mounting base 221 face opposite directions. This arrangement has a simple structure and can realize the integration of air conditioning sterilization function.

[0041] Preferably, the opening of the first mounting base 211 faces the evaporator 1, and the opening of the second mounting base 221 faces away from the evaporator 1. This arrangement allows the generated pulse light to be directed towards the evaporator 1, while the electronic control unit 22 faces the air conditioner panel side, facilitating maintenance; at the same time, it prevents the condensate generated by the evaporator 1 from flowing into the electronic control unit 22 and affecting its operational safety and stability.

[0042] As an example of the present invention, a first mounting portion 2111 is provided at the end of the first mounting base 211 away from the connecting portion 23, and a second mounting portion 223 is provided at the end of the second mounting base 221 for detachable connection with the middle frame. Preferably, the first mounting portion 2111 is an insert, and the second mounting portion 223 is a lug with an assembly hole. This configuration allows for the installation of the pulse sterilization integrated module 2 with a single screw, resulting in high assembly efficiency. Preferably, the length of the insert is L1, and the width of the groove 231 is L2, where 1.5 * L1 < L2. This configuration avoids interference between the groove 231 and the assembly of the insert.

[0043] As an example of the present invention, the germicidal lamp unit 21 further includes a sealing plug 212, a bracket 213, and a germicidal lamp 214. The bracket 213 is disposed on the side of the first mounting base 211 near the evaporator 1. The germicidal lamp 214 is disposed between the first mounting base 211 and the bracket 213. Sealing plugs 212 are disposed at both ends of the germicidal lamp 214. The germicidal lamp 214 is electrically connected to the electrical control unit 22. This arrangement has a simple structure and facilitates the assembly and disassembly of the germicidal lamp 214. Preferably, the germicidal lamp unit 21 further includes a light-transmitting plate 215 for sealing the third notch 2132. This arrangement has a simple structure and does not affect the germicidal effect of the pulsed light; at the same time, it prevents the condensate generated by the evaporator 1 from contacting the germicidal lamp 214, thereby affecting the safety of use.

[0044] As an example of the present invention, the bracket 213 is recessed inward on the side near the first mounting base 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 first mounting base 211, and the third notch 2132 communicates with the mounting cavity 2131 to allow pulsed light to pass through. This arrangement has a simple structure, and the germicidal lamp 214 can be positioned and assembled by the cooperation of the bracket 213 and the first mounting base 211. The structure is simple and easy to assemble and disassemble.

[0045] Preferably, the longitudinal height of the third notch 2132 is H1, the height of the bracket 213 is H2, and the height of the first mounting base 211 is H3, where H2-H1=H3. This arrangement ensures that the first mounting base 211 does not obstruct the light generated by the germicidal lamp 214, resulting in good sterilization effect and convenient heat dissipation. As an example of the present invention, the length of the third notch 2132 is L1, and the length of the bracket 213 is L2, where 0.6*L2<L1<0.9*L2. This arrangement can balance the sterilization performance and heat dissipation performance of the germicidal lamp section 21, while also giving it good mechanical strength and a long service life.

[0046] 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 first mounting base 211 at a position corresponding to the first buckle 2133. The first buckle 2133 can be limited and assembled into the first slot 2114. This arrangement ensures that force applied from the outer side of the first mounting base 211 is applied to the first buckle 2133, facilitating the quick removal of the bracket 213 from the first mounting base 211; at the same time, the first buckle 2133 fills the mating groove to make the side wall of the first mounting base 211 flat, resulting in a high overall aesthetic appeal. 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.

[0047] As an example of the present invention, the first mounting base 211 is provided with a first notch 2112 and a second notch 2113, which 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 2112 and the second notch 2113 may be the same or different.

[0048] 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 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.

[0049] As an example of the present invention, the electronic control unit 22 further includes a cover 222 detachably connected to the second mounting base 221, forming a closed cavity between the cover 222 and the second mounting base 221 for accommodating the circuit board. This arrangement prevents condensate from directly entering the second mounting base 221 and affecting the operational safety of the electronic control unit 22.

[0050] Preferably, the second mounting base 221 has a perimeter 2212 near the end of the cover 222, and a second buckle 2213 is provided on the perimeter 2212. A second slot 2221 is provided on the cover 222 at a corresponding position to the second buckle 2213, allowing the second buckle 2213 to be fitted into the second slot 2221. This design is simple and easy to manufacture; it also ensures the integrity of the outer surface of the cover 222, preventing condensate from easily entering through the gap between the cover 222 and the second mounting base 221, resulting in good waterproofing. Preferably, the perimeter 2212 is recessed downwards to form a clearance groove 2211 to allow the power cord to pass through. During assembly, the cover 222 can abut and limit the power cord from above, while simultaneously sealing the clearance groove 2211 to prevent it from moving back and forth, facilitating cable routing and providing good waterproofing.

[0051] During assembly, first install sealing plugs 212 on both ends of the germicidal lamp 214, then assemble it onto the first mounting base 211, and then fasten the bracket 213 onto the first mounting base 211; similarly, install the circuit board onto the second mounting base 221, and then assemble the box cover 222 onto the second mounting base 221, thereby realizing the integration of the sterilization function; then insert and fix one end of the pulse sterilization integrated module 2 to the middle frame 9, and connect and fix the other end to the middle frame 9 with screws, which is efficient and simple in wiring.

[0052] Example 2

[0053] like Figure 5-8As shown, an indoor air conditioning unit includes an air inlet, a fan 10, 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 10. The indoor air conditioning unit also includes a pulse sterilization integrated module 2 installed on the evaporator 1. The pulse sterilization integrated module 2 includes a sterilization lamp part 21 and an electronic control part 22 that are electrically connected to each other. The pulse light emitted by the sterilization lamp part 21 illuminates at least the evaporator 1. The sterilization lamp part 21 and the electronic control part 22 are fixedly assembled by a connecting part 23 and the horizontal distance between them is less than 10cm. Alternatively, the sterilization lamp part 21 and the electronic control part 22 are installed on the same mounting base.

[0054] This configuration allows the germicidal lamp unit 21 and the electronic control unit 22 to be assembled into a pulse sterilization integrated module 2, which is then assembled into the indoor unit of the air conditioner. This simplifies wiring and increases assembly efficiency. At the same time, the connection between the germicidal lamp unit 21 and the electronic control unit 22 is stable and reliable. The pulse sterilization integrated module 2 can be used to sterilize the evaporator 1 and the air duct, minimizing the impact on the normal airflow inside the air conditioner. This results in low energy consumption, good sterilization effect, and excellent user comfort.

[0055] As an example of the present invention, the pulse sterilization integrated module 2 is detachably connected to the middle frame 9 at one end and detachably connected to the evaporator 1 at the other end. As another example, the sterilization lamp unit 21 includes a first mounting base 211, with a first mounting part 2111 at the end of the first mounting base 211 away from the electronic control unit 22, for detachable connection to the middle frame 9. The electronic control unit 22 includes a second mounting base 221, with a second mounting part 223 at the end of the second mounting base 221 away from the sterilization lamp unit 21, for detachable connection to the evaporator 1. This configuration is simple in structure and provides stable and reliable assembly. The pulse sterilization integrated module 2 is constrained and assembled in the first and second directions by the first mounting part 2111 and the second mounting part 223 respectively, improving the reliability and stability of the assembly.

[0056] Preferably, the first mounting base 211 and the second mounting base 221 are integrally formed and arranged sequentially along the length of the evaporator 1. The opening of the first mounting base 211 faces the evaporator 1, and the opening of the second mounting base 221 faces away from the evaporator 1. This arrangement allows the generated pulse light to be directed towards the evaporator 1, while the electronic control unit 22 faces the panel 6 of the indoor unit of the air conditioner. After opening the panel 6, maintenance can be performed. At the same time, it prevents the condensate generated by the evaporator 1 from flowing into the electronic control unit 22, which would affect its operational safety and stability.

[0057] As an example of the present invention, the second mounting part 223 includes a first claw 2231 and a second claw 2232 that are arranged adjacently and extend to one side of the evaporator 1. The first claw 2231 and the second claw 2232 cooperate with each other to form a first limiting part for snap-fit ​​assembly with the evaporator 1.

[0058] Preferably, the first claw 2231 has a recessed portion near the second claw 2232 to form a first limiting groove, which is semi-circular; the second claw 2232 has a recessed portion near the first claw 2231 to form a second limiting groove. Both the first and second limiting grooves are semi-circular and are arranged opposite to each other. This arrangement allows the second mounting part 223 to be fitted into the evaporator 1, effectively preventing it from coming off.

[0059] Preferably, the second mounting portion 223 further includes a third latch 2233 and a fourth latch 2234. The third latch 2233 is located on the side of the first latch 2231 away from the second latch 2232, and the fourth latch 2234 is located on the side of the second latch 2232 away from the first latch 2231. A second limiting portion is formed between the first latch 2231 and the third latch 2233, and a third limiting portion is formed between the second latch 2232 and the fourth latch 2234, for engaging with the evaporator 1. This arrangement allows the second mounting portion 223 to have multiple contact points with the evaporator 1, limiting its position in the vertical plane to prevent rotation relative to the evaporator 1.

[0060] The indoor unit of the air conditioner also includes a complete unit electrical control box 3, an end cover 4, a wall-mounted plate 5, a panel 6, an air guide assembly 7, and a base 8. The wall-mounted plate 5 and the middle frame 9 are respectively installed on both sides of the base 8. The evaporator 1 is installed inside the middle frame 9. The end cover 4 is installed at the side end of the middle frame 9. The complete unit electrical control box 3 is located between the middle frame 9 and the end cover 4. The panel 6 is installed on the front side of the middle frame 9. The air guide assembly 7 is installed on the lower side of the panel 6. The above structure and assembly relationship are all existing technologies and will not be described in detail here.

[0061] During assembly, the pulse sterilization integrated module 2 is assembled first. Then, one end of the pulse sterilization integrated module 2 is snapped into the evaporator 1, and the other end is fixed to the middle frame 9 by means of screws or other methods. Alternatively, it can be fixed to the evaporator bracket. The assembly efficiency is high and the wiring is simple.

[0062] 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.
