Description

Technical Field

[0001] This utility model belongs to the field of air conditioning equipment technology, and in particular relates to an indoor air conditioning unit. Background Technology

[0002] The air outlet structure of the indoor unit of an air conditioner consists of a frame, an air guide plate, and a power mechanism that drives the air guide plate. The air guide plate is responsible for the main air guiding function. The air guide plate includes a horizontal air guide plate and a vertical air guide plate. The horizontal air guide plate rotates to change the vertical air supply direction, and the vertical air guide plate rotates to change the horizontal air supply direction.

[0003] When traditional air deflectors guide air, as the rotation angle increases, the airflow passing through the gaps between the deflectors will cause a significant decrease in air volume and an increase in air velocity, resulting in excessively fast airflow into the room and poor air delivery comfort. In addition, when the air deflector rotates at a large angle, the significant temperature difference between the windward and leeward sides of the deflector will cause condensation on one side of the deflector. Utility Model Content

[0004] The purpose of this utility model is to provide an air conditioner indoor unit to solve the problems of poor air supply comfort and condensation on both sides of the air guide plate due to the large temperature difference in the air outlet structure of existing air conditioner indoor units.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution: This utility model proposes an indoor unit for an air conditioner, comprising: an air outlet structure, wherein the air outlet structure includes: The frame has an air outlet formed on it; Multiple air guide plates are movably connected to the air outlet along the height direction of the air outlet. Multiple air guide vertical plates are movably connected to the air outlet along the length direction of the air outlet, and a through air passage is formed on the air guide plate; and / or vortex recesses are formed on both sides of the air guide plate.

[0006] In some embodiments of this application, the air passages are spaced apart along the height direction of the air guide plate, and each air passage includes a central air passage hole and peripheral air passage holes formed in a circular array around the central air passage hole.

[0007] The entire air passage is shaped like a flower, which is aesthetically pleasing.

[0008] In some embodiments of this application, the central air passage is circular, and each of the peripheral air passages is petal-shaped. The relationship between the radius R0 of the central air passage and the thickness D of the air guide plate satisfies: R0 = 0.6D~0.7D.

[0009] In some embodiments of this application, the peripheral air passage includes a first arc-shaped segment close to the central air passage, a second arc-shaped segment away from the central air passage, and a third arc-shaped segment connecting the first and second arc-shaped segments. The radius R1 of the first arc-shaped segment, the radius R2 of the second arc-shaped segment, and the radius R3 of the third arc-shaped segment are related to the thickness D of the air guide vertical plate as follows: R1=0.1D~0.2D, R2=0.2D~0.4D, R3=5.5D~6.5D.

[0010] In some embodiments of this application, the shortest distance A between the center of the peripheral air passage and the center of the intermediate air passage and the radius R0 of the intermediate air passage satisfy: A = 1.6R0 ~ 2R0.

[0011] In some embodiments of this application, the maximum width dimension M of the second arc segment and the radius dimension R0 of the intermediate air passage satisfy: M=1.4R0~4.6R0.

[0012] In some embodiments of this application, the vortex recess is a teardrop shape extending along the length of the air guide vertical plate, including a fourth arc segment and spline segments located on both sides of the fourth arc segment. The relationship between the standard radius dimension R4 of the fourth arc segment and the height G of the air guide vertical plate satisfies: R4 = 0.01G ~ 0.0175G.

[0013] In some embodiments of this application, the standard maximum width B of the vortex recess and the height G of the air guide vertical plate are related as follows: B = 0.02G ~ 0.025G; the standard maximum length C of the vortex recess and the length L of the air guide vertical plate are related as follows: C = 0.12L ~ 0.16L.

[0014] In some embodiments of this application, the relationship between the standard depth h of the vortex recess and the thickness D of the air guide vertical plate satisfies: h = 0.3D ~ 0.38D.

[0015] In some embodiments of this application, the actual size of each vortex recess on the air guide plate is a random scaling of the standard size, with the scaling range being 0.8 to 1.2 times the standard size for each vortex recess.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are: The air conditioner indoor unit involved in this application has a through-flow section formed on the air guide vertical plate of its air outlet structure. The through-flow section is beneficial to improve the air dispersion effect, reduce wind resistance, reduce the air volume attenuation problem caused by the deflection of the air guide vertical plate, and the airflow on the windward side is transported to the leeward side through the through-flow section. It is also beneficial to reduce the temperature difference between the two sides and reduce the generation of condensation. The air guide plate has vortex recesses on both sides. These vortex recesses are used to increase local vortices, making the airflow turbulent and increasing comfort. This makes the airflow output from the air outlet structure more dispersed and uniform, resulting in higher comfort.

[0026] In this application, the air conditioner performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0027] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0028] The expansion valve expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0029] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0030] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0031] refer to Figures 1-3 This utility model proposes an indoor air conditioning unit, which includes an air outlet structure. The air outlet structure includes a frame 100, a plurality of horizontal air guide plates 300 and a plurality of vertical air guide plates 200 disposed on the frame 100.

[0032] Specifically, an air outlet is formed on the frame 100, and the horizontal air guide plate 300 and the vertical air guide plate 200 are movably connected to the air outlet.

[0033] A horizontal guide plate 300 is horizontally arranged on the air outlet. There are multiple horizontal guide plates 300, which are movably connected to the air outlet along the height direction of the air outlet.

[0034] The air guide vertical plate 200 is vertically arranged on the air outlet, and there are multiple air guide vertical plates 200, which are movably connected to the air outlet along the length direction of the air outlet.

[0035] The horizontal air guide plate 300 and the vertical air guide plate 200 are arranged front and back on the air outlet along the output direction of the airflow. In other words, the horizontal air guide plate 300 is located inside the frame 100, and the vertical air guide plate 200 is located at the front of the frame 100.

[0036] The air guide plate has a through-flow section 210 to reduce airflow attenuation and lower the risk of condensation forming on the leeward side of the air guide plate; and / or the air guide plate has vortex recesses 220 on both sides to increase local vortices.

[0037] In some embodiments of this application, the air passages 210 are spaced apart along the height direction of the air guide plate, and each air passage includes a central air passage 211 and peripheral air passages 212 formed in a circular array around the central air passage 211.

[0038] The air passage 210 has a flower-shaped overall design, which is aesthetically pleasing. The smooth arc-shaped lines around the central air passage 211 and the peripheral air passage 212 facilitate smoother airflow and increase local vortices to improve airflow comfort. By increasing the airflow path through the air passage 210, the aim is to reduce airflow attenuation and the risk of condensation.

[0039] refer to Figures 4-7 For ease of understanding, the length of each air guide vertical plate 200 is defined as L, the height as G, and the thickness as D.

[0040] By specifying the structural parameters of the air passage 210, the airflow resistance is reduced and the air volume is increased while ensuring the air guiding effect. At the same time, the airflow on the leeward side of the air guide vertical plate 200 is increased, and condensation is reduced.

[0041] In some embodiments of this application, the central air passage 211 is circular, and each of the peripheral air passages 212 is petal-shaped, so the air passage 210 is flower-shaped as a whole, which is aesthetically pleasing.

[0042] The relationship between the radius R0 of the intermediate air passage 211 and the thickness D of the air guide vertical plate 200 is: R0 = 0.6D ~ 0.7D.

[0043] In some embodiments of this application, the peripheral air passage 212 includes a first arc-shaped segment 2121 close to the intermediate air passage 211, a second arc-shaped segment 2122 away from the intermediate air passage 211, and a third arc-shaped segment 2123 connecting the first arc-shaped segment 2121 and the second arc-shaped segment 2122.

[0044] The first arc segment 2121, the second arc segment 2122, and the third arc segment 2123 are connected by smooth rounded corners.

[0045] The relationship between the radius R1 of the first arc segment 2121, the radius R2 of the second arc segment 2122, and the radius R3 of the third arc segment 2123 and the thickness D of the air guide vertical plate 200 satisfies: R1=0.1D~0.2D, R2=0.2D~0.4D, R3=5.5D~6.5D.

[0046] In some embodiments of this application, the shortest distance A between the center of the peripheral air passage 212 and the center of the intermediate air passage 211 satisfies the following condition with respect to the radius R0 of the intermediate air passage 211: A = 1.6R0 ~ 2R0.

[0047] The shortest distance between the center of the peripheral air passage 212 and the center of the intermediate air passage 211 affects the structural strength of the vertical blade. When the shortest distance between the center of the peripheral air passage 212 and the center of the intermediate air passage 211 is short, the structural strength of the air guide vertical plate 200 is low. Therefore, in principle, the shorter the distance between the center of the peripheral air passage 212 and the center of the intermediate air passage 211 should be as large as possible. However, due to the blade size, the relationship between the shortest distance A between the center of the peripheral air passage 212 and the center of the intermediate air passage 211 and the radius R0 of the intermediate air passage 211 should satisfy: A = 1.6R0 ~ 2R0.

[0048] In some embodiments of this application, the maximum width M of the second arc segment 2122 and the radius R0 of the intermediate air passage 211 satisfy: M = 1.4R0 ~ 4.6R0.

[0049] The dimensions R1, R2, and R3 related to the three arc segments on the petal-shaped peripheral air passage 212 directly affect the size of the peripheral air passage 212.

[0050] When the air guide plate 200 deflects at its maximum angle, if the dimensions of R1, R2, and R3 are relatively small, the corresponding dimensions of the peripheral air passage 212 will be small, reducing the effect of airflow output from the peripheral air passage 212. This results in greater resistance of the air guide plate 200 to the airflow, leading to an increase in the attenuation of the airflow in the outlet structure.

[0051] If the air guide plate 200 has high resistance and the air volume decreases, taking heating as an example, the indoor temperature is low and the air temperature output from the air outlet is high. Therefore, the temperature of the windward side of the air guide plate 200 is high and the temperature of the leeward side is low. When the indoor air comes into contact with the leeward side, condensation is easily formed.

[0052] As the dimensions of R1, R2, and R3 increase, the resistance of the air guide plate 200 decreases, the air volume increases, and the airflow reaching the leeward side of the air guide plate 200 increases, thus reducing condensation.

[0053] However, if these three dimensions are too large, it will result in the circumferential air passage 212 being too large, increasing the airflow, reducing the airflow guided by the air guide vertical plate 200, decreasing the left and right air delivery angle, and failing to achieve the intended air guiding performance.

[0054] The air guide vertical plate 200 on the air outlet structure has a through air passage 210. The air passage 210 helps to improve the air dispersion effect, reduce wind resistance, and reduce the air volume attenuation problem caused by the deflection of the air guide vertical plate 200. The airflow on the windward side is transported to the leeward side through the air passage 210, which also helps to reduce the temperature difference between the two sides and reduce the generation of condensation.

[0055] refer to Figure 8 In some embodiments of this application, the vortex recess 220 is a teardrop shape extending along the length direction of the air guide vertical plate 200. Of course, in other embodiments, the vortex recess 220 may also be a teardrop shape extending along the height direction of the air guide vertical plate 200, or a teardrop shape at any angle to the height direction of the air guide vertical plate 200.

[0056] The dimensions of the vortex recesses 220 can be set to the same size, or, within a certain range, the dimensions of different vortex recesses 220 can be designed to be different.

[0057] Define a set of standard dimensions for the vortex recess 220, the actual dimensions of the vortex recess 220 can be within the range of these standard dimensions.

[0058] In some embodiments of this application, the actual size of each vortex recess 220 on the air guide vertical plate 200 is a random scaling of the standard size, and the scaling range is: the actual size of each vortex recess 220 is 0.8 to 1.2 times the standard size.

[0059] The vortex recess 220 includes a fourth arc segment 221 and spline segments 222 located on both sides of the fourth arc segment 221. The relationship between the standard radius dimension R4 of the fourth arc segment 221 and the height G of the air guide vertical plate 200 satisfies: R4=0.01~0.0175G.

[0060] In some embodiments of this application, the standard maximum width B of the vortex recess 220 and the height G of the air guide vertical plate 200 are related by the following condition: B = 0.02~0.025G; the standard maximum length C of the vortex recess 220 and the length L of the air guide vertical plate 200 are related by the following condition: C = 0.12~0.16L.

[0061] In some embodiments of this application, the relationship between the standard depth h of the vortex recess 220 and the thickness D of the air guide vertical plate 200 satisfies: h = 0.3~0.38D.

[0062] The vortex recess 220 can be formed on the windward side of the air guide vertical plate 200 or on the leeward side of the air guide vertical plate 200. The vortex recess 220 on the windward side and the vortex recess 220 can be arranged symmetrically or asymmetrically.

[0063] Increasing the standard radius R4 of the fourth arc segment 221 of the vortex recess 220, the standard maximum width B of the vortex recess 220, and the standard depth h of the vortex recess 220 will increase the overall size of the vortex recess 220, increase the local turbulence, and improve comfort.

[0064] However, the excessively large standard radius R4 of the fourth arc segment 221 of the vortex recess 220, the standard maximum width B of the vortex recess 220, and the standard depth h of the vortex recess 220 lead to a reduction in the strength of the vertical blade.

[0065] In particular, the standard depth h of the vortex recess 220 should be limited. If the standard depth h of the vortex recess 220 is too large, it may cause the mold to be unable to open.

[0066] In addition, the teardrop-shaped vortex recess 220 exhibits random sizes, i.e., random scaling, with a scaling range of 0.8 to 1.2 times the dimensions defined above.

[0067] The air guide plate has vortex recesses 220 on both sides. The vortex recesses 220 are used to increase local vortices, make the airflow turbulent, increase comfort, and make the airflow output from the air outlet structure more dispersed and uniform, resulting in high comfort.

[0068] The air guide plate 200 can effectively reduce air volume attenuation. In terms of air field distribution, the airflow can clearly reach the leeward side through the air passage 210 on the air guide plate 200, reducing condensation. This is also the reason why it can increase air volume. In terms of air delivery angle and blade vortex, the air delivery angle is slightly smaller, but the vortex on the surface of the air guide plate 200 is significantly increased, especially in the area around the air passage 210 and the vortex recess 220, which will increase the comfort of air delivery.

[0069] In some embodiments of this application, rotating portions 230 are formed at both ends of the air guide vertical plate 200. The rotating portions 230 are cylindrical and are arranged at the upper and lower ends of the air guide vertical plate 200 along the height direction of the air guide vertical plate 200. The air guide vertical plate 200 is movably connected to the inner side of the air outlet of the frame 100 through the rotating portions 230.

[0070] refer to Figure 3 , Figure 9 Specifically, the air outlet of the frame 100 includes a top wall and a bottom wall, with connecting protrusions formed on the top wall and the bottom wall. Connecting recesses are formed at both ends of the air guide vertical plate 200. The connecting protrusions are at least partially inserted into the connecting recesses, and the air guide vertical plate 200 is hinged to the connecting protrusions through the connecting recesses.

[0071] Each air guide vertical plate 200 is also provided with a connecting groove 240, and the transmission beam 400 is connected and fixed to each air guide vertical plate 200 through the connecting groove 240.

[0072] The transmission beam 400 is located on the outside of the air outlet structure, that is, on the side closer to the room.

[0073] The transmission beam 400 drives each air guide vertical plate 200 to rotate synchronously. The connecting groove 240 is located on the side opposite to the rotating part 230. In other words, along the length of the air guide vertical plate 200, the two rotating parts 230 are located at the first end (i.e., the air inlet end) of the air guide vertical plate 200, and the connecting groove 240 is located at the second end (i.e., the air outlet end) of the air guide vertical plate 200.

[0074] The transmission beam 400 extends along the length of the air outlet. Specifically, a control chamber 110 is provided at one end of the frame 100. A first drive unit 500 is provided inside the control chamber 110. The output end of the first drive unit 500 is connected to a connecting rod 510. The transmission beam 400 is hinged to the connecting rod 510.

[0075] When the air guide plate 200 is opened, the first drive unit 500 is activated, driving the connecting rod 510 to rotate. The rotation of the connecting rod 510 drives the transmission beam 400 to move left and right along the length of the air outlet. Since the end of the connecting rod 510 moves in an arc shape, the transmission beam 400 will also move back and forth along the direction of airflow while moving left and right. Correspondingly, it drives the air guide plate 200 to rotate the switch with the rotating part 230 as the rotation center.

[0076] Specifically, along the length of the air outlet, the rotation center of the rotating part 230 and the rotation center of the output end of the first drive part 500 are on the same straight line, and the connection position of the connecting rod part 510 and the transmission beam 400 and the connection position of the transmission beam 400 and the air guide vertical plate 200 are on the same straight line. Therefore, it can be ensured that the movement trajectory of the connecting rod part 510 and the air guide vertical plate 200 is consistent.

[0077] Combination Figure 1 An avoidance portion is formed on the side wall of the control room 110. The linkage portion 510 passes through the avoidance portion and is connected to the first drive portion 500. When the first drive portion 500 is opened, the linkage portion 510 moves within the avoidance portion. The avoidance portion is used to prevent the linkage portion 510 from interfering with the side wall of the control room 110 during its movement.

[0078] Correspondingly, the other end of the connecting rod 510 is also movably connected to the connecting wall 120 on the opposite side of the control room 110. The connecting wall 120 is also provided with a clearance part. The connection and drive between the connecting rod 510 and the first drive part 500 and the air guide vertical plate 200 are existing technologies and are not the focus of this application. They will not be described in detail here.

[0079] refer to Figure 10 In some embodiments of this application, the control room 110 is further provided with a second drive unit 600 for driving the air guide plate 300, and the second drive unit 600 is connected to one end of the air guide plate 300.

[0080] The number of the second drive unit 600 and the number of the air guide plate 300 are in one-to-one correspondence, and they are used to drive the movement of each air guide plate 300.

[0081] A sealing section 320 is provided between two adjacent air guide horizontal plates 300. In the closed state, the air guide horizontal plate 300 above the sealing section 320 rotates downward to connect with the sealing section 320, and the air guide horizontal plate 300 at the bottom is connected to the bottom of the frame 100.

[0082] In some embodiments of this application, a plurality of support plates 130 are also provided at intervals on the air outlet of the frame 100, and a rotating support plate 310 is formed on the air guide plate 300, the rotating support plate 310 being rotatably connected to the support plate 130.

[0083] The support plate 130 provides support for the air guide plate 300, improving the stability of the air guide plate 300's rotation.

[0084] The indoor unit of the air conditioner involved in this application has a through-flow section 210 formed on the air outlet structure of the air guide vertical plate 200. The through-flow section 210 is conducive to improving the air dispersion effect, reducing wind resistance, reducing the air volume attenuation problem caused by the deflection of the air guide vertical plate 200, and the airflow on the windward side is transported to the leeward side through the through-flow section 210. It is also conducive to reducing the temperature difference between the two sides and reducing the generation of condensation.

[0085] The air guide vertical plate 200 has vortex recesses 220 on both sides. The vortex recesses 220 are used to increase local vortices, make the airflow turbulent, increase comfort, and make the airflow output from the air outlet structure more dispersed and uniform, resulting in high comfort.

[0086] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0087] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0088] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
