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] Indoor air quality is closely related to human health. During flu season, if there are carriers of infectious viruses in poorly ventilated indoor spaces, cross-infection may occur. In winter, to ensure the effectiveness of air conditioning, doors and windows are often closed for extended periods, and the repeated circulation of indoor air further increases the probability of cross-infection.

[0003] Many domestic and foreign manufacturers have proposed the concept of integrating sterilization functions into air conditioners. The main sterilization methods include UVC deep ultraviolet light, nano water ions, plasma, ozone, electrostatic dust collection, self-cleaning + high temperature, etc. Each of these sterilization methods has its own advantages and disadvantages, but they all have some shortcomings, such as the sterilization rate needs to be improved, the user's perception of the sterilization process is weak, and the sterilization process is not very visible.

[0004] A novel sterilization technology, pulsed sterilization, is currently available. It releases energy in the form of full-spectrum white light within an extremely short time through the self-ionization of inert gas and avalanche discharge. The instantaneous photoelectric power can reach 10 million times that of ordinary sunlight, instantly killing various microorganisms without causing significant temperature changes to the object being sterilized. While it has already been applied in water disinfection, food hygiene processing, and medical care, its miniaturization has not yet been widely adopted in the air conditioning industry.

[0005] Pulse sterilization typically uses xenon lamps, and due to the installation structure, it is heavier and larger than traditional UVC modules. Therefore, it requires more space for installation and must have a certain load-bearing capacity. Additionally, pulse sterilization requires a high-voltage pulsed electricity supply, necessitating a large capacitor in the electrical module. Thus, the installation location of the electrical module must also consider load-bearing capacity, space, and wiring. Furthermore, the installation space for indoor air conditioning units, especially wall-mounted units, is often limited. The optimal location for installing the pulse light source module must minimize the increase in overall unit size, save costs, and facilitate assembly. All of these factors must be considered.

[0006] In view of this, the present invention is hereby proposed. Summary of the Invention

[0007] The problem solved by this invention is to optimize the installation position and structure of the pulse light source module, thereby enhancing the user experience of the sterilization function.

[0008] To address the aforementioned problems, the present invention provides an indoor air conditioning unit, comprising a middle frame, a panel disposed on the outer side of the middle frame, an evaporator disposed on the inner side of the middle frame, and a pulse sterilization component fixedly mounted on the middle frame, the pulse sterilization component being located between the evaporator and the panel, the pulse sterilization component comprising a pulse light source module and a pulse electronic control module electrically connected to each other, the pulse light source module and the pulse electronic control module being arranged along the length direction of the middle frame.

[0009] This setup makes full use of the internal space of the air conditioner's indoor unit. At the same time, the pulse sterilization component can be inspected and maintained by opening the panel. It can sterilize the evaporator and the air intake grille located on the upper part of the indoor unit at the same time. The entire pulse sterilization component is located on the upper front side of the evaporator, so it will not interfere with the airflow inside the evaporator. The structure is reasonable and provides a good user experience.

[0010] Preferably, the evaporator includes a first heat exchange section, a second heat exchange section, and a third heat exchange section connected at an angle in sequence, and the pulse sterilization component is located between the second heat exchange section and the panel. This arrangement allows the pulse sterilization component to be directly installed on the upper part of the middle frame, minimizing the obstruction of airflow by the pulse sterilization component when the sterilization function is not activated; at the same time, it allows the pulse waves or light generated to radiate the evaporator as widely as possible, covering a wide range.

[0011] Preferably, the indoor unit of the air conditioner includes a main control box, which is located on one side along the length of the evaporator, and the pulse light source module is located on the side of the pulse electronic control module away from the main control box. This arrangement is simple in structure and facilitates wiring.

[0012] Preferably, the middle frame includes a first vertical support column, a second vertical support column, and a third vertical support column arranged sequentially along its length. The two ends of the pulse light source module are respectively mounted on the first and second vertical support columns. A bracket is integrally formed between the second and third vertical support columns, and the pulse electronic control module is mounted on the bracket. This arrangement, by mounting the pulse light source module and the pulse electronic control module at different positions on the middle frame, helps to distribute the load; it also makes full use of the internal space of the air conditioner and requires minimal modification to the existing structure.

[0013] Preferably, the bracket is detachably connected to the pulse control module. The bracket has a cavity for housing the pulse control module, and the bottom surface of the cavity has a hollow section. This design allows it to be integrally formed, ensuring mechanical strength to meet assembly requirements; simultaneously, the hollow section facilitates heat dissipation of the pulse control module after assembly. The hollow section can be composed of round holes, square holes, or hollow patterns, and its characteristic is that it is connected to the interior of the middle frame, which is beneficial for utilizing the cooling energy generated by the evaporator for heat exchange and cooling.

[0014] Preferably, a second slot is provided on one side of the cavity, and a second insert is provided on the pulse control module at a position corresponding to the second slot. The second insert can be positioned and fitted into the second slot. This arrangement can serve as a pre-positioning function, facilitating the rapid assembly of the pulse control module.

[0015] Preferably, a fixing post is provided on the side of the cavity away from the second slot, and a second connecting plate is provided on the pulse control module at a position corresponding to the fixing post. The second connecting plate has mounting holes, which are detachably connected to the fixing post. This arrangement allows for the fixing of the pulse control module through plug-in or screw connection, resulting in reliable and efficient assembly.

[0016] Preferably, the pulse light source module includes a fixing seat on the middle frame, a bracket on the side of the fixing seat away from the panel, a pulse germicidal lamp between the fixing seat and the bracket, the pulse germicidal lamp being electrically connected to the pulse electronic control module, and sealing plugs being provided at both ends of the pulse germicidal lamp.

[0017] Preferably, the fixing base includes a base plate, and a first side plate and a second side plate are provided on one side of the base plate. There is a gap between the first side plate and the second side plate for limiting the assembly of the bracket.

[0018] Preferably, a first insert is provided at one end of the base plate, and a first connecting plate is provided on the side of the first vertical support column near the second vertical support column. The first connecting plate has a first slot, and the first insert can limit the device to enter the first slot. The first connecting plate serves a pre-positioning function, resulting in high assembly efficiency. Preferably, the first connecting plate is located on the first vertical support column and extends towards the evaporator. This arrangement allows the pulse sterilization module to be positioned close to the evaporator, fully utilizing the internal space of the air conditioner and achieving good sterilization effect.

[0019] Preferably, a connecting plate is provided at the end of the base plate away from the first insert, and a second connecting plate is provided on the side of the second vertical support column near the first vertical support column. The connecting plate and the second connecting plate are detachably connected. This configuration has a simple structure and high assembly efficiency.

[0020] Compared with the prior art, the air conditioner indoor unit of the present invention has the following beneficial effects: 1) The pulse sterilization component can be inspected after the panel of the air conditioner indoor unit is opened. The pulse sterilization component can sterilize the evaporator and the air inlet grille located on the upper part of the indoor unit at the same time, with a wide radiation range; 2) The air conditioner indoor unit can make full use of the internal space of the air conditioner indoor unit with little modification to the existing structure; 3) The structure is simple and easy to manufacture.

Detailed Implementation

[0034] 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, unless otherwise specified, the technical features of the various embodiments of the present invention can be combined with each other.

[0035] 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.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of 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 "under" 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.

[0037] When an air conditioner operates in cooling mode, the indoor evaporator produces condensate, which provides favorable conditions for the growth and proliferation of bacteria and other microorganisms. This can easily lead to discomfort or even "air conditioning sickness" in people. Therefore, air conditioners with sterilization functions have emerged; however, their current structure is complex and unreasonable, resulting in poor overall performance. Therefore, the applicant proposes the following technical solution:

[0038] like Figure 1-7 As shown, an indoor unit of an air conditioner includes a middle frame 9, a panel 6 is arranged on the outer side of the middle frame 9, an evaporator 1 is arranged on the inner side of the middle frame 9, and a pulse sterilization component 2 is fixedly installed on the upper part of the middle frame 9. The pulse sterilization component 2 is located between the middle frame 9 and the panel 6. The pulse sterilization component 2 includes a pulse light source module 21 and a pulse electronic control module 22 that are electrically connected to each other. The pulse light source module 21 and the pulse electronic control module 22 are arranged along the length direction of the middle frame 9.

[0039] This setup makes full use of the internal space of the air conditioner unit. At the same time, the pulse sterilization component 2 can be inspected after opening panel 6. It can sterilize the evaporator 1 and the air intake grille located on the upper part of the indoor unit at the same time. The entire pulse sterilization component 2 is located on the upper front side of the evaporator 1, which will not interfere with the air flow inside the evaporator 1. The structure is reasonable and the user experience is good.

[0040] The air conditioner also includes an electrical control box 3, a right end cover 4, a left end cover 5, an air guide assembly 7, a base 8, and a wall-mounted panel 10. The wall-mounted panel 10 and a middle frame 9 are respectively installed on both sides of the base 8. A cross-flow fan is installed inside the evaporator 1. The left end cover 5 and the electrical control box 3 are respectively installed on both sides of the middle frame 9. The right end cover 4 is installed around the electrical control box 3. A panel 6 is installed on the front side of the middle frame 9, and the air guide assembly 7 is installed on the lower side of the panel 6. The above structures and assembly relationships are all existing technologies and will not be described in detail here. In this invention, no filter is installed on the panel 6, which will not interfere with the assembly of the pulse sterilization assembly 2.

[0041] As an example of the present invention, the evaporator 1 includes a first heat exchange section 11, a second heat exchange section 12 and a third heat exchange section 13 connected in sequence at an angle. The first heat exchange section 11, the second heat exchange section 12 and the third heat exchange section 13 are located around the flow fan blades and the second heat exchange section 12 is located between the first heat exchange section 11 and the third heat exchange section 13. The pulse sterilization component 2 is located between the second heat exchange section 12 and the panel 6.

[0042] This configuration allows the pulse sterilization component 2 to be directly installed on the upper part of the middle frame 9, minimizing the obstruction of airflow by the pulse sterilization component 2 when the sterilization function is not activated; at the same time, it allows the pulse waves or light generated to radiate to the evaporator 9 as much as possible, with a wide coverage area.

[0043] Preferably, a wire-locking buckle is provided on the middle frame 9, located between the pulse light source module 21 and the pulse electronic control module 22, to limit the connection between the pulse electronic control module 22 and the electronic control box 3. This setting can make full use of the existing middle frame 9 structure and facilitates production and processing.

[0044] As an example of the present invention, the middle frame 9 includes a first vertical support column 91, a second vertical support column 92, and a third vertical support column 93 arranged sequentially along its length. The two ends of the pulse light source module 21 are respectively mounted on the first vertical support column 91 and the second vertical support column 92. A bracket 94 is integrally formed between the second vertical support column 92 and the third vertical support column 93, and the pulse electronic control module 22 is mounted on the bracket 94. This arrangement, by mounting the pulse light source module 21 and the pulse electronic control module 22 at different positions on the middle frame 9, facilitates the distribution of load; it also makes full use of the internal space of the air conditioner with minimal modification to the existing structure.

[0045] As an example of the present invention, a first connecting plate 911 is provided on the side of the first vertical support column 91 near the second vertical support column 92. The first vertical connecting plate 911 extends along the length direction of the second vertical support column 92 and is provided with a slot. A second connecting plate 921 is provided on the side of the second vertical support column 92 near the first vertical support column 91. The second connecting plate 921 is perpendicular to the first connecting plate 911 and extends along the length direction of the middle frame 9. The second connecting plate 921 is provided with an assembly hole. The first connecting plate 911 and the second connecting plate 921 are used together for the limiting assembly of the pulse sterilization module 21.

[0046] This configuration positions the pulse sterilization module 21 entirely on the side of the middle frame 9 closest to the evaporator 1, resulting in excellent sterilization of the evaporator 1 and its internal air ducts. It also minimizes the increase in the size of the indoor air conditioning unit, requiring minimal modification to existing air conditioning systems and facilitating implementation. Preferably, the first connecting plate 911 and the first vertical support column 91 are integrally formed. This configuration ensures stable and reliable assembly of the pulse sterilization module 21.

[0047] As an example of the present invention, the bracket 94 is provided with a cavity 941, and the bottom surface of the cavity 941 is provided with a hollow portion 942. Preferably, the cavity 941 is formed by a downward indentation of the bracket 94. This design makes it integrally formed, and the mechanical strength meets the assembly requirements; at the same time, the hollow portion 942 is beneficial for heat dissipation of the pulse electronic control module 22 after assembly. The hollow portion 942 can be composed of round holes, square holes, or hollow patterns, and its characteristic is that it is connected to the interior of the middle frame 2, which is beneficial for utilizing the cold energy generated by the evaporator 1 for heat exchange and cooling.

[0048] Preferably, a second slot 943 is provided on one side of the cavity 941, and a fixing post 944 is provided on the other side of the cavity 941. The second slot 943 and the fixing post 944 cooperate to quickly assemble the pulse control module 22.

[0049] like Figure 8 As shown, the pulse light source module 21 includes a mounting base 211 on the middle frame 9, a bracket 212 on the side of the mounting base 211 away from the panel 6, a pulse germicidal lamp 213 between the mounting base 211 and the bracket 212, and sealing plugs 214 at both ends of the pulse germicidal lamp 213. The pulse germicidal lamp 213 is electrically connected to the pulse electronic control module 22. This arrangement can make full use of the internal space of the air conditioner indoor unit with minimal changes to the existing structure; at the same time, it ensures that the light or pulse emitted by the pulse germicidal lamp 213 is directed towards the air inlet side, that is, the top of the air conditioner, and will not cause harm to the user.

[0050] like Figure 9 As shown, the fixing base 211 includes a base plate 2111. A first side plate 2112 and a second side plate 2113 are provided on one side of the base plate 2111. There is a gap between the first side plate 2112 and the second side plate 2113 for limiting the assembly bracket 212.

[0051] Preferably, a connecting plate 2114 is provided at one end of the base plate 2111 for screwing and fixing to the first connecting plate 911; a first insert 2115 is provided at the end of the base plate 2111 away from the connecting plate 2114 for inserting and fixing to the second connecting plate 921. This configuration is simple in structure, and the pulse light source module 21 can be quickly disassembled and assembled after opening the panel 6, which is convenient for maintenance.

[0052] As an example of the present invention, a baffle 2117 is provided at least one end of the base plate 2111, and the baffle 2117 is provided perpendicular to the base plate 2111. This arrangement can shield the pulse germicidal lamp 213 from both sides to prevent foreign objects from contacting the pulse germicidal lamp 213 and causing damage.

[0053] like Figure 10 As shown, the bracket 212 is recessed inward on the side near the fixed base 211 to form a limiting groove 2121. A first notch 2122 is provided at one end of the limiting groove 2121 for passing through the power cord. A second notch 2124 is provided on the side of the bracket 212 away from the fixed base 211, and the second notch 2124 is connected to the limiting groove 2121.

[0054] Preferably, the longitudinal height of the second notch 2124 is H1, and the height of the bracket 212 is H2, where 0.4*H2 < H1 < 0.8*H1. This arrangement ensures that the fixing base 211 does not obstruct the light generated by the pulse germicidal lamp 213, resulting in good sterilization effect and convenient heat dissipation. As an example of the present invention, the length of the second notch 2124 is L1, and the length of the bracket 212 is L2, where 0.6*L2 < L1 < 0.9*L2. This arrangement improves the sterilization and heat dissipation performance of the pulse light source module 21, while also giving it good mechanical strength and a long service life.

[0055] As an example of the present invention, a buckle 2123 is provided on the outer side of the bracket 212, and a slot 2116 is provided on the fixing seat 211 at a corresponding position to the buckle 2123. The buckle 2123 can be limited and assembled into the slot 2116. This arrangement allows force to be applied to the buckle 2123 from the outside of the fixing seat 211, facilitating quick assembly and disassembly of the bracket 212 and the fixing seat 211; at the same time, the buckle 2123 fills the mating groove to make the side wall of the fixing seat 211 flat, resulting in a high overall aesthetic appearance.

[0056] Preferably, buckles 2123 are provided on both sides of the bracket 212, and slots 2116 are provided on the first side plate 2112 and the second side plate 2113 at positions corresponding to the buckles 2123. The structure is simple and balances assembly sturdiness and ease of use. The pulse germicidal lamp 213 can be a xenon lamp or an ultraviolet lamp; preferably, the pulse germicidal lamp 213 is a xenon lamp, outputting a high-level pulse of 5ms every 1 second, requiring an excitation time of 2 seconds, for a total of 120 pulses. The pulse frequency of the pulse germicidal lamp 213 can be adjusted according to the number of bacteria, for example, by starting fast and then slowing down within each sterilization cycle.

[0057] During assembly, first install sealing plugs 214 on both ends of the pulse germicidal lamp 213, install the pulse germicidal lamp 213 into the limiting groove 2121 of the bracket 212, and then snap the bracket 212 onto the fixing seat 211 to form the pulse light source module 21. After that, assemble the pulse light source module 21 onto the middle frame 9 through the connecting plate 2114 and the first insert 2115. The power cord of the pulse germicidal lamp 213 is connected to the pulse electronic control module 22, and the connecting wire of the pulse electronic control module 22 is routed along the wire clip on the middle frame 9 to the electronic control box 3.

[0058] like Figure 11 As shown, the pulse control module 22 includes a detachably connected cover 221 and a housing 222, with the housing 222 partially embedded within the cover 221. Preferably, a baffle 2222 is provided on the side of the housing 222 near the cover 221, and the outer wall of the baffle 2222 is not in close contact with the inner wall of the cover 221. This arrangement allows the pulse control module 22 to have good sealing performance and good waterproof effect. As an example of the present invention, the baffle 2222 is provided with a clearance groove, and the cover 221 is provided with a mating groove at a corresponding position for passing through the clearance groove, for the power cord.

[0059] Preferably, a second insert 2223 is provided at one end of the box body 222, which can be positioned and fitted into the second slot 943 of the bracket 94; a second connecting plate 2221 is provided at the end of the box body 222 away from the second insert 2223, and a first connecting plate 2211 is provided at the corresponding position of the lid 221 and the second connecting plate 2221. The first connecting plate 2211, the second connecting plate 2221 and the fixing post 944 are connected by screws. This arrangement can fix the box body 222, the lid 221 and the middle frame 9 with a single screw, resulting in high assembly efficiency. During assembly, the lid 221 is aligned with the evaporator 1, one end of the box body 222 is inserted into the middle frame 9, and the other end is screwed to the middle frame 9 for fixation. The structure is simple and the production cost is low.

[0060] 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.
