Description

Technical Field

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

[0002] With the development of the times, air conditioners have become one of the essential household appliances in daily life. During use, external air can carry bacteria into the air conditioner, and due to the condensation caused by the temperature difference between hot and cold inside the air conditioner, each component is sometimes in a humid environment, making it easy for bacteria to breed. The spread of bacteria with the air blown by the air conditioner may affect people's health; for this reason, air conditioners with a sterilization function have emerged.

[0003] The mature sterilization technology used in air conditioners, such as UVC ultraviolet sterilization, requires a long sterilization time. Plastic parts are easily aged when exposed to UVC ultraviolet rays for a long time; UVC ultraviolet leakage is likely to cause harm to the human body and may also generate ozone and other defects.

[0004] As a new type of sterilization technology, pulsed sterilization technology can release energy in the form of full-spectrum white light through the self-ionization and avalanche discharge of inert gases in an extremely short time. The instantaneous light power can reach 10 million times that of ordinary sunlight, which can instantly kill various microorganisms without bringing obvious temperature changes to the sterilized object. It has been applied in water disinfection, food hygiene treatment, and medical and health fields, but its miniaturization has not been promoted in the air conditioner field.

[0005] Pulsed sterilization usually uses a xenon lamp tube, plus the installation structure, which is heavier than the traditional UVC module. Therefore, its installation position requires a certain load-bearing capacity; and the xenon lamp tube is brighter during operation. Since the air conditioner housing is usually made of plastic and has a certain light transmittance, the light transmittance problem of the xenon lamp tube also needs to be considered. For this reason, the Chinese patent with the application number 202210717582.X, as the applicant's prior application, discloses an indoor unit of an air conditioner and an air conditioner, in which the evaporator bracket has a connection bracket opposite to the air outlet, and the connection bracket is provided with a UV sterilization module and the UV irradiation direction is towards the inside of the connection bracket and deviates from the air outlet. This solution can effectively prevent ultraviolet light from emitting from the air outlet, but its contact time with the air flow is short, the sterilization effect is not ideal, and it may emit from the air outlet and cause damage to the user.

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

[0007] The problem solved by the present invention is that the unreasonable structure of the existing indoor unit of the air conditioner leads to an unsatisfactory sterilization effect and easy light leakage, which is not conducive to the health of users.

[0008] To solve the above problems, the present invention provides an air conditioner indoor unit, including an evaporator bracket and a pulsed sterilization assembly. The pulsed sterilization assembly includes a pulsed light source module. The evaporator bracket has a side bracket disposed opposite to the air outlet. An evaporator is provided inside the side bracket. The pulsed light source module is horizontally installed in the side bracket, and one end of the pulsed light source module away from the air outlet is plugged and connected to the evaporator.

[0009] This setting can increase the contact time between the air flow and the light generated by the pulsed light source to improve the sterilization effect. At the same time, only one end of the pulsed light source module is close to the air outlet. Even if some sterilization light penetrates out of the air outlet, its proportion is relatively small; it makes full use of the internal space of the air conditioner cabinet, with a compact structure and small modification. Preferably, the air conditioner indoor unit is an air conditioner cabinet. The evaporator bracket is placed vertically, and the length direction of the pulsed light source module is perpendicular to the length direction of the evaporator bracket.

[0010] Preferably, an outer frame is provided on the side of the side bracket close to the air outlet. The pulsed light source module is fixedly connected to the outer frame. The irradiation direction of the light generated by the pulsed light source module faces the inside of the side bracket and deviates from the air outlet. This setting can ensure that the light generated by the pulsed light source module is not easily penetrated out of the air outlet. The pulsed light source module is located on one side of the air outlet. Since the air velocities on both sides in the width direction of the air inlet of the cabinet air conditioner are about 5 - 65% higher than the air velocity in the middle, the air flow velocity at the position where the pulsed light source module is located is relatively large, further improving the cleanliness of the air flow blown out by the indoor unit to improve the user experience.

[0011] Preferably, the pulsed sterilization assembly further includes a pulsed electronic control module. The pulsed light source module is electrically connected to the pulsed electronic control module. There are multiple pulsed light source modules arranged at intervals along the length direction of the side bracket. This setting can irradiate the air flow in different areas inside the air conditioner indoor unit, shorten the maximum distance between the air flow and the pulsed light source module, and improve the sufficiency of the air flow inside the unit being irradiated by ultraviolet light, thereby improving the sterilization and disinfection effect. Preferably, there are multiple pulsed light source modules arranged at equal intervals along the length direction of the side bracket.

[0012] Preferably, the pulsed light source module includes a fixedly connected base and a bracket. The bracket is located on the side of the base close to the evaporator. A sterilization lamp is provided between the base and the bracket. A light-transmitting hole is provided at a position on the bracket corresponding to the sterilization lamp for the light generated by the sterilization lamp to pass through. This setting has a simple structure, can constrain the irradiation direction of the light generated by the sterilization lamp, and is convenient for the replacement, disassembly and assembly of the sterilization lamp.

[0013] Preferably, a sealing plug is provided at the end of the germicidal lamp, and a rubber protective sleeve is provided on the side of the sealing plug away from the germicidal lamp; the pulse light source module further includes a cover shell made of quartz glass for blocking the light-transmitting hole, and the rubber protective sleeve is sleeved on the end of the cover shell. This setting can seal the area where the germicidal lamp is located, with good waterproof effect and safe and reliable operation.

[0014] Preferably, the fixing base includes a bottom plate, and first side plates and second side plates parallel to each other are respectively provided on the upper and lower sides of the bottom plate. A first inclined plate is provided on the side of the first side plate away from the bottom plate, and a second inclined plate is provided on the side of the second side plate away from the bottom plate. The opening angle formed between the first inclined plate and the second inclined plate is 0-90°. This setting can avoid interfering with the light of the germicidal lamp and increase its coverage; at the same time, the ends of the first inclined plate and the second inclined plate are in contact with the evaporator, which can increase its assembly stability.

[0015] Preferably, a first fixing ear is provided at the end of the second inclined plate away from the bottom plate, and the first fixing ear extends outward along the plane where the bottom plate is located; first end plates and second end plates are respectively provided at the left and right ends of the bottom plate. A plug-in portion is provided on the side of the first end plate away from the bottom plate for detachably connecting with the evaporator, and a second fixing ear is provided on the second end plate, and the second fixing ear is perpendicular to the plug-in portion for abutting or screwing and assembling with the peripheral frame. This setting enables the fixing base to be connected to the peripheral frame through the first fixing ear and the second fixing ear, and is fixedly connected to the evaporator by the plug-in portion. The assembly structure is simple and the connection is firm; the pulse light source module can be installed on both floor-standing air conditioners and wall-mounted air conditioners at the same time, with strong versatility.

[0016] Preferably, the bottom plate is provided with a limit groove for limiting and assembling the germicidal lamp. The distances from the limit groove to the first side plate and the second side plate are A1 and A2 respectively, where A1 > A2.

[0017] This setting can make full use of the existing structure of the indoor unit of the air conditioner with little modification; a sufficient buffer space is formed in the upper part of the fixing base, which is beneficial to heat dissipation, and at the same time, an insulating effect is generated by using this space, effectively avoiding the accumulation of condensed water and having a good waterproof effect; the limit groove is located in the lower part of the fixing base. When the air is blown, even if condensed water is formed, it will directly drip under the action of gravity without affecting the operation of the pulse light source module. At this time, the heat generated by the germicidal lamp can be taken away and has a good heat dissipation effect.

[0018] Preferably, the bracket has a second assembly space, which has a light-transmitting hole and an annular plate. The annular plate is located on the periphery of the light-transmitting hole and extends toward the side of the bracket away from the fixed seat. The periphery of the annular plate is provided with a first reinforcing rib. This setting can strengthen the bracket and at the same time constrain the light passing through the light-transmitting hole to prevent it from passing through the air outlet and causing harm to the user.

[0019] Preferably, a connecting plate in an L shape is arranged on the side part of the bracket along the length direction. A first assembly space is formed between the connecting plate and the bracket. A second reinforcing rib is arranged on the inner side of the connecting plate and extends along the width direction of the bracket. A buckle is arranged on the outer side of the connecting plate. The second reinforcing rib is located at a position corresponding to the buckle in the first assembly space.

[0020] This setting can increase the strength of the buckle and prevent damage caused by uneven force application during the assembly process. At the same time, it can prevent the condensed water generated in the second limiting space from flowing randomly in the length direction of the bracket and avoid the condensed water from gathering towards the germicidal lamp, with good waterproof effect.

[0021] Compared with the prior art, the air conditioner indoor unit of the present invention has the following beneficial effects: 1) increasing the contact time between the air flow and the light generated by the pulsed light source to improve the sterilization effect, and the operation is safer and more reliable; 2) a buffer space is formed on the upper side of the pulsed light source module to facilitate heat dissipation, and at the same time, a heat insulation effect is generated to avoid the generation of condensed water; 3) making full use of the internal space of the existing air conditioner indoor unit, with little modification to the existing structure and stable and reliable assembly.

Detailed implementation manners

[0041] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention is provided with reference to the accompanying drawings. It should be noted that, without conflict, the technical features in various embodiments of the present invention can be combined with each other.

[0042] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0043] In the present invention, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature. The above and below, left and right orientation definitions in the present invention are described after the air conditioner is normally installed and facing the front panel of the air conditioner. For a cabinet machine, it is the orientation recognized by a person facing the air outlet.

[0044] An air conditioner adjusts the indoor temperature by exchanging heat with air to provide a comfortable environment. When it gets dirty and blocked, it is cleaned to effectively remove bacteria and the like inside the air conditioner. However, in the summer cooling mode, the indoor evaporator will generate condensate water, which provides favorable conditions for the growth of bacteria and other microorganisms. A large number of remaining bacteria and other microorganisms will cause discomfort to the human body and even lead to "air conditioner disease". For this reason, air conditioners with bactericidal functions have emerged. However, their current structures are complex and unreasonable, resulting in poor overall performance of the air conditioners. Therefore, the applicant proposes the following technical solutions:

[0045] As Figure 1-7 shown, an indoor unit of an air conditioner includes an evaporator bracket 4 and a pulsed sterilization component 1. The pulsed sterilization component 1 includes a pulsed light source module 2. The evaporator bracket 4 has a side bracket 42 disposed opposite to the air outlet. An evaporator is provided inside the side bracket 42. The side bracket 42 has a peripheral frame 421. The pulsed light source module 2 is horizontally installed on the peripheral frame 421. One end of the pulsed light source module 2 away from the peripheral frame 421 is inserted and connected to the evaporator.

[0046] The air flow entering the indoor unit of the air conditioner is blown out from the air outlet after passing through the evaporator bracket 4. The side bracket 42 is the part of the evaporator bracket 4 disposed opposite to the air outlet of the indoor unit of the air conditioner. In this embodiment, setting the pulsed light source module 2 on the peripheral frame 421 can sterilize the air flow blown out from the air outlet. At the same time, horizontally setting the pulsed light source module 2 can increase the contact time with the outgoing air flow to further improve the sterilization effect. It is ensured that only one end of the pulsed light source module 2 is close to the air outlet. Even if some sterilization light rays penetrate out from the air outlet, their proportion is relatively small. The internal space of the air conditioner cabinet is fully utilized, and the structure is compact with little modification.

[0047] Preferably, the irradiation direction of the light generated by the pulsed light source module 2 is towards the inside of the side bracket 42 and deviates from the air outlet. This setting ensures that the light generated by the pulsed light source module 2 is not easily penetrated out from the air outlet. Tests have shown that the wind speeds on both sides in the width direction of the air inlet of the cabinet air conditioner are about 5 - 65% higher than the wind speed in the middle. The air flow velocity near the peripheral frame 421 is relatively large, which further improves the cleanliness of the air flow blown out by the indoor unit to improve the user experience.

[0048] Preferably, the pulsed light source module 2 can be set to multiple ones, and the pulsed light source modules 2 are arranged at intervals along the length direction of the side bracket 42. This setting can irradiate the air flows in different areas inside the indoor unit of the air conditioner, shorten the maximum distance between the air flow and the pulsed light source module 2, and improve the sufficiency of the air flow inside the unit being irradiated by ultraviolet light. Thus, the sterilization and disinfection effect can be improved.

[0049] The air conditioner indoor unit also includes a detachably connected front panel assembly 7 and a rear panel assembly 6. A top cover 10 is provided on the top of the front panel assembly 7 and the rear panel assembly 6, and a base 9 is provided on the bottom, which together form the appearance of the air conditioner indoor unit. The air conditioner indoor unit also includes a reinforcing strip 8, which is located between the front panel assembly 7 and the rear panel assembly 6 and is vertically arranged. Its structure and assembly relationship are prior art. The evaporator bracket 4 is arranged opposite to the front panel assembly 7 and includes an upper bracket 41, a side bracket 42 and a lower bracket 43 that are connected to each other to form a whole. The side bracket 42 is located between the upper bracket 41 and the lower bracket 43. Preferably, the upper bracket 41 and the lower bracket 43 are connected to the side bracket 42 by a snap-on structure.

[0050] The duct assembly 5 is arranged in the evaporator bracket 4, and the cabinet electric control box 11 is arranged on the top of the duct assembly 5. This arrangement enables the cabinet electric control box 11 to be located above the duct assembly 5, and the condensed water generated will not drip onto the cabinet electric control box 11, and the operation is safe and stable. The duct assembly 5 includes a wind wheel and a motor, and the motor is installed on the upper bracket 41. The motor is connected to the wind wheel to drive the wind wheel to rotate, thereby generating airflow, and sending the heat-exchanged air out of the air conditioner indoor unit through the air outlet.

[0051] Preferably, the side bracket 42 includes a peripheral frame 421, an arc-shaped support rod 422, and a vertical support rod 423. There are multiple arc-shaped support rods 422 and they are arranged in an arc shape. The arc-shaped support rods 422 are connected to the side away from the peripheral frame 421 through the vertical support rod 423. This arrangement makes the side bracket 42 have good mechanical strength and simple structure.

[0052] Preferably, an assembly hole 4211 is provided on the outer frame 421, and the pulse light source module 2 includes a fixing seat 21, and a first fixing ear 2132 is provided at a position corresponding to the fixing seat 21 and the assembly hole 4211, and the first fixing ear 2132 and the assembly hole 4211 are fixed by bolts; the outer frame 421 is provided with a limiting groove 4212 on the side close to the air outlet, and a second fixing ear 2151 is provided at a position corresponding to the fixing seat 21 and the limiting groove 4212, and the second fixing ear 2151 is abutted against the limiting groove 4212 or screwed together.

[0053] like Figure 8 As shown, the pulse light source module 2 includes a fixing seat 21, a bracket 22 is arranged on the side of the fixing seat 21 close to the evaporator, a germicidal lamp 23 is arranged between the fixing seat 21 and the bracket 22, and a light-transmitting hole 224 is arranged on the bracket 22 for light to pass through; a sealing plug 25 is arranged at the end of the germicidal lamp 23, and a rubber protective cover 24 is arranged on the side of the sealing plug 25 away from the germicidal lamp 23, and the germicidal lamp 23 is electrically connected to the pulse electric control module 3. This setting structure is simple and easy to disassemble and assemble. Preferably, the pulse light source module 2 also includes a cover 26, and the material of the cover 26 is quartz glass, which is used to block the light-transmitting hole 224.

[0054] likeFigures 9-11 As shown, the fixed seat 21 includes a bottom plate 211. On both sides of the bottom plate 211, a first side plate 212 and a second side plate 213 perpendicular to the bottom plate 211 are respectively provided. On the side of the first side plate 212 away from the bottom plate 211, a first inclined plate 2122 is provided. On the side of the second side plate 213 away from the bottom plate 211, a second inclined plate 2131 is provided. The opening angle formed between the first inclined plate 2122 and the second inclined plate 2131 is 0 - 90°. The lengths of the first inclined plate 2122 and the second inclined plate 2131 are L1 and L2 respectively, and the lengths of the light-transmitting hole 224 and the fixed seat 21 are L3 and L4 respectively, where L1 = L2 = L3 = (0.6 - 0.8) * L4. This setting can avoid interfering with the light of the germicidal lamp 23 and increase its coverage range.

[0055] Preferably, a first fixing ear 2132 is provided on the side of the second inclined plate 2131 close to and away from the bottom plate 211. The second fixing ear 2132 is in the same plane as the bottom plate 211 and is used for screwing and assembling with the peripheral frame 421. Preferably, there is a height difference between the first fixing ear 2132 and the second fixing ear 2151. This setting can make full use of the structure of the existing peripheral frame 421, so that the entire fixed seat 21 fits the evaporator and is basically not protruded from the peripheral frame 421, and at the same time forms a support for the pulse light source module 2 in the three-dimensional space, with better stability.

[0056] Preferably, a first end plate 214 and a second end plate 215 are respectively provided at the left and right ends of the bottom plate 211. On the side of the first end plate 214 away from the bottom plate 211, a plug-in portion 2141 is provided for detachably connecting with the evaporator. The second end plate 215 is provided with a second fixing ear 2151, and the second fixing ear 2151 is perpendicular to the plug-in portion 2141 and is used for limiting and fixing with the limiting groove 4212. This setting enables the fixed seat 21 to be connected to the peripheral frame 421 through the first fixing ear 2132 and the second fixing ear 2151, and the plug-in portion 2141 is used for plugging and fixing with the evaporator, and the assembly structure is simple and the connection is reliable.

[0057] As an example of the present invention, the plug-in portion 2141 includes a first claw and a second claw arranged adjacent to each other and extending towards the evaporator side. The first claw and the second claw cooperate with each other to form a first limiting portion for clamping and assembling with the evaporation tube of the evaporator.

[0058] A part of the side of the first claw close to the second claw is recessed to form a first limiting groove, and the first limiting groove is in a "semicircular" shape; a part of the side of the second claw close to the first claw is recessed to form a second limiting groove, and the first limiting groove is in a "semicircular" shape and is arranged opposite to the first limiting groove. This setting can limit and assemble the evaporation tube into the first limiting groove and the second limiting groove to prevent it from coming out.

[0059] Preferably, the insertion part 2141 further includes a third claw and a fourth claw. The third claw is located on the side of the first claw away from the second claw, and the fourth claw is located on the side of the second claw away from the first claw. A second limiting part is formed between the first claw and the third claw, and a third limiting part is formed between the second claw and the fourth claw for snap - fitting assembly with the evaporator. This setting enables the insertion part 2141 to be in line contact with the evaporator, and limits it in the vertical plane to prevent it from rotating relative to the evaporator, while the insertion part 2141 can limit the fixing base 21 in the horizontal plane to prevent it from sliding.

[0060] Preferably, the bottom plate 211 is provided with a limiting groove 2111 for limiting and assembling the germicidal lamp 23. The distances from the limiting groove 2111 to the first side plate 212 and the second side plate 213 are A1 and A2 respectively, where A1 > A2. This setting can make full use of the existing structure of the air - conditioner indoor unit with little modification; a sufficient buffer space is formed in the upper part of the fixing base 21, which is beneficial to heat dissipation, and at the same time uses this space to produce a heat - insulation effect, effectively avoiding the accumulation of condensed water and having a good waterproof effect; and the limiting groove 2111 is located in the lower part of the fixing base 21, so that a sufficient buffer space is formed in the upper part of the fixing base 21, and the lower part of the fixing base 21 can be in full contact with the heat - exchange air flow for heat dissipation; when blowing air, even if condensed water is formed, it will directly drip under the action of gravity without affecting the operation of the pulsed light source module 2, and at this time, the heat generated by the germicidal lamp 23 can be taken away and has a good heat - dissipation effect.

[0061] Preferably, the bottom plate 211 is provided with a limiting plate 2112. The limiting plate 2112 is located at the end of the limiting groove 2111 and is connected to the first end plate 214 or the second end plate 215. This setting can increase the mechanical strength of the fixing base 21 and has a long service life.

[0062] Preferably, the first side plate 212 and the second side plate 213 are respectively provided with a card slot 2121, and a buckle 227 is provided at a position on the bracket 22 corresponding to the card slot 2121. The buckle 227 can be limited and assembled into the card slot 2121. This setting makes the bracket 22 and the fixing base 21 detachably connected, which is convenient for disassembly and assembly and has high maintenance efficiency.

[0063] As Figures 12-15 shown, the bracket 22 has a second assembly space 223. A connecting plate 221 in an L - shape is provided on the side of the bracket 22, and the connecting plate 221 forms a first assembly space 222. The second assembly space 223 has a light - transmitting hole 224 and an annular plate 225. The annular plate 225 is located on the periphery of the light - transmitting hole 224 and extends towards the side of the bracket 22 away from the fixing base 21. The periphery of the annular plate 225 is provided with a first reinforcing rib 226. This setting can strengthen the bracket 22 and at the same time constrain the light passing through the light - transmitting hole 224, effectively preventing it from passing through the air outlet and causing harm to users.

[0064] Preferably, the depth of the second assembly space 223 is greater than that of the first assembly space 222. This setting can make full use of the space between the side bracket 42 and the evaporator, with little modification to the existing air conditioner indoor unit, facilitating production and processing and having good assembly stability.

An electric control box body 34 and an electric control box cover 33 are arranged between the explosion-proof box body 32 and the explosion-proof box cover 31. Part of the electric control box body 34 is embedded in the explosion-proof box body 32, and the electric control box body 34 is detachably connected to the electric control box cover 33. This setting can improve the explosion-proof and waterproof performance of the pulsed electric control module 3, and the operation is safer and more stable.

[0068] During assembly, the cover shell 26 is assembled to the light-transmitting hole 224 of the bracket 22. Then, both ends of the germicidal lamp 23 are successively assembled with the sealing plug 25 and the rubber protection sleeve 24 and then installed in the cover shell 26. Then, the fixing seat 21 is snap-connected to the bracket 22 to form the pulsed light source module 2; the pulsed light source module 2 is horizontally assembled to the outer peripheral frame 421 of the side bracket 42 and electrically connected to the pulsed electric control module 3; wherein the bottom plate 211 of the fixing seat 21 is placed vertically, one end of the fixing seat 21 is inserted into the evaporator, the other end of the second fixing ear 2151 abuts against or is screwed to the outer peripheral frame 421, and at the same time, the first fixing ear 2132 on one side of the fixing seat 21 is screwed to the outer peripheral frame 421 for stable and reliable connection; this setting can increase the contact time between the heat exchange air flow and the pulsed sterilization light, improve the sterilization efficiency; at the same time, it can significantly reduce the pulsed sterilization light leaking from the air outlet under the same conditions, with good user experience.

[0069] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
