Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and specifically provides a fresh air air conditioner. Background Technology

[0002] Currently, air conditioners are used by an increasing number of people in their daily lives, and their fresh air function is becoming increasingly sophisticated. However, existing fresh air conditioners rely on motors to control the on / off of the fresh air system, and the fresh air function shuts off when the air conditioner is turned off, nor can it be turned on again when the air conditioner is turned off. There are currently no air conditioners with manual control over the fresh air function. This significantly limits the use of fresh air conditioners and negatively impacts the user experience.

[0003] As people's living standards improve, users have increasingly higher requirements for indoor air quality, thus necessitating the use of fresh air systems to improve indoor air quality. However, the operation of existing fresh air conditioning systems is limited by the start and stop of the air conditioner; the fresh air system can only be activated after the air conditioner is turned on, and cannot be manually controlled independently, leading to energy waste.

[0004] Therefore, there is a need in the field for an air conditioner with manually controllable fresh air volume to solve the above problems. Summary of the Invention

[0010] In the preferred technical solution of the above-mentioned fresh air air conditioner, the connecting shaft includes a bearing seat disposed on the connecting arm and a first engaging structure disposed on the top of the bearing seat, and a second engaging structure is provided at the bottom of the control switch. The control switch and the connecting shaft are engaged and connected through the first engaging structure and the second engaging structure.

[0011] In the preferred technical solution of the above-mentioned fresh air air conditioner, the first engaging structure includes a protrusion formed on the top of the bearing seat, and the second engaging structure includes a groove formed on the bottom of the control switch, wherein the protrusion engages with the groove.

[0012] In the preferred technical solution of the above-mentioned fresh air air conditioner, the connecting rod includes a first part and a second part extending obliquely upward from the first part. The first part is provided with a first sliding groove and a second sliding groove. The connecting end of the fresh air baffle is provided with a second rotating shaft. The second rotating shaft is slidably connected to the second sliding groove, and the connecting rod can rotate around the second rotating shaft. The first rotating shaft is disposed on the inner wall of the end cover of the air conditioner housing. The first rotating shaft is slidably connected to the first sliding groove, and the connecting rod can rotate around the first rotating shaft. The connecting arm is disposed on the second part, and the connecting arm is connected to the second part through the fixed shaft.

[0013] In the preferred technical solution of the above-mentioned fresh air air conditioner, the fresh air baffle includes a third part and a fourth part extending horizontally from the first end of the third part. The third part is located inside the fresh air housing and can extend and retract relative to the fresh air housing to open and close the fresh air mechanism.

[0014] In the preferred technical solution of the above-mentioned fresh air air conditioner, the angle between the extension direction of the first part and the extension direction of the second part is less than 90°; and / or the first part and the second part are integrally formed.

[0015] In the preferred technical solution of the above-mentioned fresh air air conditioner, the length of the second slide groove is greater than the length of the first slide groove.

[0016] In a preferred embodiment of the fresh air conditioner of the present invention, the fresh air conditioner includes an air conditioner housing, a fresh air mechanism, and a control mechanism.

[0017] Furthermore, the fresh air mechanism includes a fresh air housing and a fresh air baffle disposed within the fresh air housing. The fresh air housing has a first through hole, and the connecting end of the fresh air baffle passes through the first through hole and connects to a transmission assembly. The fresh air baffle can extend and retract relative to the fresh air housing to open and close the fresh air mechanism. By controlling the fresh air switch, the fresh air baffle can be extended to different degrees, which not only opens and closes the fresh air mechanism but also obtains different fresh air volumes, making the fresh air volume adjustable to meet different user needs and further enhance the user experience.

Detailed Implementation

[0029] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the specification describes the length of the first sliding groove on the connecting rod of the fresh air conditioner of the present invention as greater than the length of the second sliding groove, the technical solution of the present invention is not limited thereto. The length of the first sliding groove on the connecting rod of the fresh air conditioner of the present invention can obviously be set to be less than or equal to the length of the second sliding groove, as long as the rotation requirements of the connecting rod are met. Such a change does not deviate from the principles and scope of the present invention.

[0030] It should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," "bottom," "top," "outer," and "inner," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "connection" and "configuration" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] As indicated in the background section, the operation of existing fresh air conditioning systems is limited by the start and stop of the fresh air conditioner. The fresh air system can only be activated after the fresh air conditioner is turned on, and cannot be manually controlled independently, leading to energy waste. This invention provides a fresh air conditioner designed to solve the problem of the inability to control the fresh air system independently, enabling the independent activation of the fresh air mechanism and improving the user experience.

[0033] First see Figure 1 The present invention will now describe a fresh air air conditioner. Figure 1 This is a structural diagram of the fresh air air conditioner of the present invention.

[0034] like Figure 1 As shown, the fresh air conditioner of the present invention includes an air conditioner housing 1, a fresh air mechanism 2, and a control mechanism 3. The fresh air mechanism 2 is disposed inside the air conditioner housing 1. The control mechanism 3 includes a control switch 31 and a transmission assembly 32. The control switch 31 is disposed on the air conditioner housing 1 and is connected to the fresh air mechanism 2 through the transmission assembly 32, so that the control switch 31 can open and close the fresh air mechanism 2 under the action of external force. With the above structural configuration, the fresh air mechanism 2 of the fresh air conditioner can be manually opened by controlling the control switch 31, whether the fresh air conditioner is off or on. Especially when the fresh air conditioner is off, the fresh air mechanism 2 can be opened without starting the fresh air conditioner, avoiding energy waste, making operation more flexible and convenient, and improving the user experience.

[0035] Preferably, the control switch 31 is located on the outer wall of the end cover (not shown in the figure) of the air conditioner housing 1. Of course, the control switch 31 can also be located on other parts such as the front panel of the air conditioner housing 1.

[0036] Preferably, the cross-section of the control switch 31 is oblong. Of course, the cross-section of the control switch 31 can also be set to other shapes such as square or arc, which will not be listed here.

[0037] It should be noted that an oblong shape consists of four sides connected end to end, with two opposite sides being straight lines and the other two opposite sides being arcs.

[0038] Preferably, the fresh air mechanism 2 is located on the left side of the air conditioner housing 1 (i.e., Figure 1 (Positioned on the left side of the paper). Of course, in practical applications, the fresh air mechanism 2 can also be placed on the right side of the air conditioner housing 1 (i.e., on the left side of the paper). Figure 1 Alternatively, the fresh air mechanism 2 can be installed on both the left and right sides of the air conditioner housing 1 (located on the right side of the paper). Those skilled in the art can flexibly adjust the location of the fresh air mechanism 2 according to actual product needs.

[0039] The following reference Figures 1 to 3 The fresh air mechanism 2 of the present invention will be described below. Figure 2 This is a structural diagram of the fresh air system of the fresh air air conditioner of the present invention in the closed state; Figure 3 This is a structural diagram of the fresh air system of the fresh air air conditioner of the present invention in the open state.

[0040] like Figures 1 to 3 As shown, the fresh air mechanism 2 includes a fresh air housing 21 and a fresh air baffle 22 disposed inside the fresh air housing 21. The fresh air housing 21 is provided with a first through hole 211, and the connecting end of the fresh air baffle 22 (i.e., Figure 2 The fresh air baffle 22 (located at the right end of the paper) passes through the first through hole 211 and is connected to the transmission assembly 32. The fresh air baffle 22 can extend and retract relative to the fresh air housing 21 to open and close the fresh air mechanism 2. That is, under the action of the transmission assembly 32, the fresh air baffle 22 can extend and retract relative to the fresh air housing 21 to open and close the fresh air mechanism 2. In other words, the fresh air baffle 22 can extend and retract along the length direction of the fresh air baffle 22 (i.e., the end located on the right side of the paper) through the first through hole 211 and connect to the transmission assembly 32. Figure 2 The fresh air baffle 22 can be moved from left to right to different degrees from the fresh air housing 21. This not only opens and closes the fresh air mechanism 2, but also provides different fresh air volumes, making the fresh air volume adjustable to meet different user needs and further enhance the user experience.

[0041] The fresh air housing 21 is provided with a fresh air inlet 212 and a fresh air outlet 213, which are located along the air intake direction of the fresh air housing 21 (i.e., Figure 2 The fresh air baffle 22 (in the direction indicated by the middle arrow) is located at both ends of the fresh air housing 21, and is located in the fresh air duct formed between the fresh air inlet 212 and the fresh air outlet 213.

[0042] Preferably, the fresh air baffle 22 includes a third part 221 and a fourth part 222. The third part 221 is located inside the fresh air duct and can extend and retract relative to the fresh air housing 21 to open and close the fresh air mechanism 2. That is, the third part 221 moves along the length direction of the fresh air baffle 22 under the action of the transmission assembly 32; the fourth part 222 extends from the first end of the third part 221 (i.e., Figure 2 The middle part extends horizontally (i.e., along the length of the third part) from the right end of the paper, and at the top of the first end of the fourth part 222 (i.e., the connecting end of the fresh air baffle 22). Figure 2 The second rotating shaft 223 is located at one end of the fourth part 222 (located on the right side of the paper and facing upwards). The first end of the fourth part 222 passes through the first through hole 211 and is connected to the transmission assembly 32 via the second rotating shaft 223. Alternatively, the second rotating shaft 223 can be located at the bottom of the first end of the fourth part 222 (i.e., the lower end of the first end of the fourth part 222). Figure 2 The position of the second rotating shaft 223 can be flexibly adjusted by those skilled in the art, such as in the part below the paper (the part facing the center).

[0043] like Figure 2 As shown, when the fresh air mechanism 2 is in the closed state, the second end of the third part 221 (i.e. Figure 2 The middle end (located on the left side of the paper) abuts against the inner wall of the fresh air housing 21, thereby closing the fresh air duct and preventing the fresh air entering the fresh air duct from the fresh air inlet 212 from entering the room through the fresh air outlet 213.

[0044] like Figure 3 As shown, when the fresh air mechanism 2 is in the open state, there is a gap between the second end of the third part 221 and the inner wall of the fresh air housing 21. This gap allows the fresh air entering the fresh air duct from the fresh air inlet 212 to enter the room through the fresh air outlet 213. Moreover, the size of the gap determines the size of the fresh air volume, and the two are directly proportional, so that the fresh air volume can be adjusted.

[0045] Furthermore, the third part 221 and the fourth part 222 are integrally formed, and this integral structure facilitates the processing and manufacturing of the mold. Of course, the third part 221 and the fourth part 222 can also be connected to each other.

[0046] Of course, the structure of the fresh air baffle 22 is not limited to the structure listed above. For example, the fresh air baffle 22 may only include the third part 221, the length of the third part 221 is greater than the width of the fresh air duct, and a second rotating shaft 223 is provided at the first end of the third part 221. No matter how it is set, as long as the fresh air baffle 22 can open and close the fresh air mechanism 2 under the action of the control mechanism 3, it is acceptable.

[0047] The following reference Figures 1 to 5The transmission assembly 32 of the present invention will be described below. Figure 4 This is a structural diagram of the control mechanism of the fresh air air conditioner of the present invention; Figure 5 yes Figure 4 A magnified view of a section at point I.

[0048] like Figures 1 to 3 As shown, the transmission assembly 32 includes a connecting rod 321, a connecting arm 322, a fixed shaft 323, a connecting shaft 324, and a first rotating shaft 325, wherein the first end of the connecting rod 321 (i.e., Figure 2 The middle end (located on the left side of the paper) is connected to the first end of the fourth part 222 in a transmission connection, and the connecting arm 322 is located at the second end of the connecting rod 321 (i.e., the end ... Figure 2 The control switch 31 is located at one end on the right side of the paper. The connecting arm 322 and the connecting rod 321 are connected by a fixed shaft 323, and the control switch 31 is connected to the connecting arm 322 by a connecting shaft 324. The first rotating shaft 325 is set on the inner wall of the end cover of the air conditioner housing 1, and the connecting rod 321 is connected to the inner wall of the end cover of the air conditioner housing 1 through the first rotating shaft 325. The transmission assembly 32 uses the connecting rod 321 structure to cleverly connect the control switch 31 and the fresh air baffle 22. By simply rotating the control switch 31, the opening and closing of the fresh air mechanism 2 and the individual adjustment of the fresh air volume can be realized at the same time. The operation is more convenient, avoiding energy waste caused by turning on the air conditioner and further improving the user experience.

[0049] like Figure 1 and Figure 4 As shown, the air conditioner housing 1 has a second through hole (not shown in the figure), and the connecting shaft 324 is mounted on the connecting arm 322. The connecting shaft 324 passes through the second through hole and connects to the control switch 31. Of course, the connecting shaft 324 can also be mounted on the control switch 31, with the connecting shaft 324 passing through the second through hole and connecting to the connecting arm 322. Those skilled in the art can flexibly adjust the position of the connecting shaft 324, as long as the control switch 31 is connected to the connecting arm 322.

[0050] like Figure 4 and Figure 5 As shown, the connecting shaft 324 includes a shaft seat 3241 and a protrusion 3242 (i.e., the first engaging structure) on the top of the shaft seat 3241. The shaft seat 3241 is fixedly mounted on the connecting arm 322. The bottom of the control switch 31 is provided with a groove 311 (i.e., the second engaging structure). The protrusion 3242 engages with the groove 311, thereby realizing the engaging connection between the control switch 31 and the connecting shaft 324. Of course, the first engaging structure 3242 and the second engaging structure 311 can also be a structure of a slot and a hook, or a structure of a claw and a rib. Regardless of the engaging structure adopted, as long as the control switch 31 can be fixed on the connecting arm 322 in an engaging manner, it is acceptable.

[0051] Furthermore, the connection between the control switch 31 and the connecting arm 322 via the connecting shaft 324 is not limited to the snap-fit ​​connection listed above. Alternatively, the first end of the connecting shaft 324 can be fixedly connected to the connecting arm 322, and the second end of the connecting shaft 324 can be threadedly connected to the control switch 31. Or, both ends of the connecting shaft 324 can be threadedly connected to the control switch 31 and the connecting arm 322 respectively. Regardless of the method used, as long as the control switch 31 and the connecting arm 322 can be securely connected and the control switch 31 can drive the connecting arm 322 to rotate together, it is acceptable.

[0052] like Figure 4 As shown, the connecting rod 321 includes a first part 3211 and a second part 3212, the second part 3212 extending from the first end of the first part 3211 (i.e., Figure 4 The part located below the surface of the paper extends obliquely upwards (i.e., Figure 4 Extending upwards and to the right from the center, the first part 3211 is provided with a first sliding groove 32111 and a second sliding groove 32112. A second rotating shaft 223, which is provided on the fourth part 222 of the fresh air baffle 22, is slidably connected to the second sliding groove 32112, and a connecting rod 321 can rotate around the second rotating shaft 223. A first rotating shaft 325, which is provided on the inner wall of the end cover of the air conditioner housing 1, is slidably connected to the first sliding groove 32111, and a connecting rod 321 can rotate around the first rotating shaft 325. A connecting arm 322 is provided on the second part 3212, and the connecting arm 322 is connected to the second part 3212 through a fixed shaft 323. Of course, the second part 3212 can also extend upwards at an angle from the middle part or near the first end of the first part 3211. Those skilled in the art can flexibly adjust the connection part of the first part 3211 and the second part 3212.

[0053] Furthermore, the angle between the extension direction of the first part 3211 and the extension direction of the second part 3212 is less than 90°, for example, 85°, 80°, 75°, or 70° or other angles, which reduces the rotation radius of the connecting rod 321, enabling the connecting rod 321 to rotate within a limited space and allowing the fresh air baffle 22 to be pulled out to different degrees. This not only allows the fresh air mechanism 2 to be opened and closed, but also allows the fresh air volume to be adjusted.

[0054] Furthermore, the first part 3211 and the second part 3212 are integrally formed, and the integrally formed structure facilitates the processing and manufacturing of the mold. Of course, the first part 3211 and the second part 3212 can also be connected to each other.

[0055] Preferably, the first groove 32111 is close to the first end of the first portion 3211, and the second groove 32112 is close to the second end of the first portion 3211 (i.e., Figure 4(The part located above the paper) Since the rotation radius of different parts of the connecting rod 321 is different, the length of the second slide groove 32112 is set to be greater than the length of the first slide groove 32111. Furthermore, the length of the second slide groove 32112 is set to the minimum length that allows the connecting rod 321 to rotate around the second rotating shaft 223 and pull out the third part 221 of the fresh air baffle 22 to a preset degree. The length of the first slide groove 32111 is set to the minimum length that allows the connecting rod 321 to rotate around the second rotating shaft 223 and pull out the fresh air baffle 22 to a preset degree. This allows the connecting rod 321 to rotate around the first rotating shaft 325 and the second rotating shaft 223, pull out the third part 221 of the fresh air baffle 22 to a preset degree, and also plays a positioning role, that is, positioning the closed position and the maximum open position of the fresh air baffle 22. The preset degree can be to completely pull out the third part 221 of the fresh air baffle 22 from the fresh air duct, or pull out 80%, or pull out 70%, or pull out 30%, etc., and the corresponding control switch 31 can rotate 90°, 80°, 70° or 30°, etc.

[0056] Of course, the length of the second slide rail 32112 can also be set to be equal to or less than the length of the first slide rail 32111. In this case, the length of the second slide rail 32112 needs to be set to the minimum length that allows the connecting rod 321 to rotate around the second pivot 223 and pull out the third part 221 of the fresh air baffle 22 to a preset extent, or greater than the minimum length, thus reducing the weight of the connecting rod 321. In other words, those skilled in the art can flexibly adjust the lengths of the first slide rail 32111 and the second slide rail 32112 according to actual product requirements.

[0057] like Figure 5 As shown, the first end of the second part 3212 (i.e. Figure 5 The first connecting hole 32121 is provided at the end above the paper surface, and the second end of the connecting rod 321 is provided at the first end of the connecting arm 322 (i.e., the first end of the connecting arm 322 is provided at the second end of the connecting rod 321). Figure 5 The second part 3212 (located at the end above the paper) is provided with a second connecting hole 3221 that is perpendicular to the first connecting hole 32121. The fixed shaft 323 passes through the first connecting hole 32121 and the second connecting hole 3221 to securely connect the second part 3212 to the connecting arm 322. It should be noted that the second part 3212 and the connecting arm 322 can rotate relative to each other or not.

[0058] like Figure 1 As shown, the fresh air air conditioner also includes a decorative strip 11, which is disposed on the outer wall of the air conditioner housing 1. When the fresh air mechanism 2 is in the closed state, the first end of the decorative strip 11 (i.e., Figure 1 The end located on the left side of the paper) and the first end of the control switch 31 (i.e. Figure 1The control switch 31 located on the right side of the paper is close to each other, so that the control switch 31 on the air conditioner housing 1 does not appear obtrusive, making the appearance of the fresh air air conditioner more beautiful and improving the user's visual effect.

[0059] The following reference Figures 1 to 3 The method of using the fresh air air conditioner of the present invention will be described.

[0060] like Figure 1 and Figure 2 As shown, the fresh air mechanism 2 is currently in the closed state. To open the fresh air mechanism 2, the first end of the control switch 31 is rotated downwards around the first pivot 325, causing the first end of the connecting arm 322 to also rotate downwards. This results in the first end of the connecting arm 322 being subjected to a downward force, which in turn causes the second end of the connecting rod 321 to be subjected to a downward force. Consequently, the second end of the connecting rod 321 rotates around the first pivot 325 located on the inner wall of the end cover of the air conditioner housing 1, and the first pivot 325 slides relative to the first slide groove 32111, making a downward arc motion. Simultaneously, the second end of the connecting rod 321 rotates around the second pivot 223 located at the connecting end of the fresh air baffle 22, and the second pivot 223 slides relative to the second slide groove 32112, thereby pulling the fresh air baffle 22 out to different degrees to open the fresh air mechanism 2. Figure 3 As shown. For example, when the first end of the control switch 31 rotates downward by 90° around the first rotating shaft 325, the fresh air baffle 22 is pulled out to the maximum extent and the fresh air volume is the maximum. The rotation angle of the control switch 31 can be determined according to the required fresh air volume.

[0061] Furthermore, when it is necessary to shut down the fresh air mechanism 2, the first end of the control switch 31 can be rotated upward around the first rotating shaft 325.
