Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning dust removal, and in particular to an air-conditioning unit that is easy to remove dust. Background Art

[0002] Air conditioning, also known as air conditioner, refers to equipment that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. It generally includes several major parts such as cold source / heat source equipment, cold and hot medium distribution system, terminal device and other auxiliary equipment, mainly including refrigeration host, water pump, fan and piping system. The terminal device is responsible for using the distributed cold and heat to specifically process the air state so that the air parameters of the target environment meet the requirements.

[0003] If an air conditioner isn't cleaned for a long time, dust and bacteria will accumulate inside it. When the air conditioner is running, a large number of bacteria will be carried into the room by the air. Living and working in such an environment for a long time can easily lead to dizziness, fatigue, colds, fevers, and other illnesses, which we call "air conditioning sickness." Therefore, it's important to regularly remove dust from the inside of the air conditioner.

[0004] There is a technical solution in the prior art that uses a movable brush rod to clean the filter at the air outlet of the air conditioner, but it is unable to clean the air guide plate at the air outlet of the air conditioner. The air guide plate is the only way for the air flow blown out by the air conditioner. The dust attached to the air guide plate is very likely to be inhaled by people along with the air flow. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an air conditioning unit that is easy to remove dust.

[0006] The object of the present invention is achieved through the following technical solutions:

[0012] Preferably, one driving rod is provided corresponding to one wind deflector, and a torsion spring is connected to the rotating shaft of the wind deflector, so that the driving rod can push the wind deflector to rotate when it is pushed out.

[0013] Preferably, there are two driving rods corresponding to the wind guide plate, and two driving blocks corresponding to the two driving rods are provided on the side wall of the power rod. The two driving inclined surfaces on the two driving blocks are adapted to have opposite inclination directions, and the axial projections of the two driving rods are distributed on both sides of the rotation axis of the wind guide plate.

[0014] Preferably, the cross-section of the clip is fan-shaped, and the center of the clip coincides with the rotation axis of the air guide plate.

[0016] Preferably, an electromagnet is provided on the mounting rod, and the electromagnet can adsorb the driving rod when energized to keep the driving rod relatively fixed; the driving block is also adapted to be elastically set, and the spring coefficient of the spring connected to the driving block is greater than the spring coefficient of the spring connected to the driving rod; when the driving rod is fixed, the power rod can move axially to drive the driving rod to push out the driving block; when the driving rod is not fixed, the power rod can move axially to drive the driving block to push out the driving rod; the cleaning member is also adapted to be elastically set, and the driving block can push the cleaning member to move toward the side of the filter when it is pushed out.

[0017] The beneficial effects of the present invention are:

[0020] 3. The rotation of the air guide plate is achieved by pushing out the driving rod arranged on the mounting rod, which simplifies the driving structure of the air guide plate and makes the internal structure of the air conditioner more compact. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0030] like Figures 1 to 7 As shown, an air conditioning unit with easy dust removal includes an air conditioner body 1. An air outlet 2 is formed at the top of the air conditioner body 1. An air guide plate 4 and a filter 3 are arranged in sequence along the depth direction of the air outlet 2. The filter 3 is used to filter the airflow from the air conditioner. The air guide plate 4 can rotate to direct the airflow in a desired direction. For example, the axis of the air guide plate 4 can extend horizontally, allowing the airflow to change direction vertically. Generally, the air guide plate 4 can be adjusted by manual or electric rotation to achieve the desired direction.

[0031] A mounting rod 5 is movably disposed within the air outlet 2, between the filter 3 and the air deflector 4. For example, the mounting rod 5 can be moved by a screw-type transfer mechanism (not shown). This screw-type transfer mechanism is conventional, and its operating principle and structure are not described in detail in this disclosure. Furthermore, a cleaning member 6 is disposed on the mounting rod 5, facing the side of the filter 3. For example, the cleaning member 6 can abut the filter 3. Thus, during the movement of the mounting rod 5, the cleaning member 6 can clean the filter 3.

[0032] In the present disclosure, the mounting rod 5 is specifically adapted to move along the length of the air deflector 4, meaning that the screw is installed parallel to the air deflector 4. Furthermore, a cleaning sleeve 7 is sleeved onto the air deflector 4 and adapted to be driven by the movement of the mounting rod 5 to move along the air deflector 4, thereby enabling the cleaning sleeve 7 to simultaneously clean the air deflector 4. The driving mechanism between the mounting rod 5 and the cleaning sleeve 7 will be discussed in detail below, in conjunction with several embodiments.

[0033] In some embodiments, the mounting rod 5 and the cleaning cover 7 can be fixedly connected by means of a fixed lock or bolt (not shown), in which case the air deflector 4 can be adapted to have a fixed air guide angle. For example, the cleaning cover 7 and the air deflector 4 can be adapted to be detachable, so that the air deflector 4 can be controlled to change the air guide angle first, and then the cleaning cover 7 can be installed on the air deflector 4.

[0034] In a possible embodiment, the mounting rod 5 and the cleaning sleeve 7 can be connected by magnetic attraction (not shown). As the mounting rod 5 moves along the length of the air deflector 4, the cleaning sleeve 7 can be attracted by the magnetic force and move, seemingly suspended, over the air deflector 4 to clean the area. For example, the generation and disappearance of the magnetic force can be controlled to unlock and reengage the cleaning sleeve 7 and the mounting rod 5. Alternatively, the magnetic force can be optimized to allow the cleaning sleeve 7 to rotate with the air deflector 4 while also being driven by the mounting rod 5 to move along the air deflector 4.

[0035] like Figures 2 to 5 As shown, in other embodiments, a clamping seat 8 is provided on the side wall of the mounting rod 5, and a clip 9 is correspondingly provided on the side wall of the cleaning sleeve 7, and the clip 9 is engaged in the clamping seat 8. It can be understood that when the mounting rod 5 moves, the clamping seat 8 will drive the cleaning sleeve 7 to move synchronously by clamping the clip 9, but the rotational freedom of the clip 9 in the clamping seat 8 is not restricted, thereby allowing the clip 9 to swing in the clamping seat 8 and the air deflector 4 to rotate.

[0036] Although the movement of the mounting rod 5 and the cleaning sleeve 7 and the rotation of the air deflector 4 do not interfere with each other in the present disclosure, if the air deflector 4 is rotated electrically, at least two actuators must be installed in the air outlet 2 of the air conditioner, namely, an actuator for driving the movement of the mounting rod 5 and an actuator for driving the rotation of the air deflector 4. This may ultimately lead to an increase in the size of the air conditioner.

[0037] In order to solve the above technical problems, in the present disclosure, a retractable driving rod 10 is further provided on the side wall of the mounting rod 5 , and the wind deflector 4 is driven to rotate by the retraction and extension of the driving rod 10 .

[0038] like Figure 3 As shown, in some embodiments, a torsion spring (not shown) can be connected to the rotating shaft of the air guide plate 4, so as to drive the air guide plate 4 to always tend to maintain a vertical state, for example. And the driving rod 10 is set to correspond to the air guide plate 4. When the wind guide angle of the air guide plate 4 needs to be changed, the driving rod 10 can be controlled to push the air guide plate 4 to rotate, and the control of the wind guide angle depends on the ejection length of the driving rod 10. For example, the driving rod 10 can also be controlled to perform regular telescopic movements. With the cooperation of the torsion spring, the air guide plate 4 will show periodic swinging, thereby realizing the wind sweeping function of the air conditioner.

[0039] In a possible example, two drive rods 10 may be provided corresponding to the wind deflector rods, with the axial projections of the two drive rods 10 distributed on both sides of the rotation axis of the wind deflector 4. In this example, the rotating shaft on the wind deflector 4 does not need to be connected to a torsion spring, and the forward and reverse rotation of the wind deflector 4 is achieved by respectively extending and retracting the two drive rods 10.

[0040] It is understandable that, for example, Figure 4 As shown in FIG, when the air deflector 4 needs to rotate clockwise, the upper drive rod 10 can be controlled to push out and the lower drive rod 10 can be controlled to retract, thereby driving the air deflector 4 to rotate clockwise; similarly, when the air deflector 4 needs to rotate counterclockwise, the lower drive rod 10 can be controlled to push out and the upper drive rod 10 can be controlled to retract. When both drive rods 10 are in the initial position, the air deflector 4 remains in a vertical position to close the air outlet 2 of the air conditioner.

[0041] like Figure 5 As shown, in other embodiments, the cross-section of the adaptable clip 9 is sector-shaped, and the center of the clip 9 coincides with the rotation axis of the air deflector 4. Furthermore, a gear 17 is rotatably mounted within the clip seat 8, and toothed structures 18 are provided on the sidewalls of the clip 9 and the sidewalls of the drive rod 10. The gear 17 engages with both toothed structures 18 simultaneously.

[0042] It can be imagined that in this example, when the drive rod 10 is pushed out, the drive rod 10 will drive the gear 17 to rotate, and then the gear 17 will drive the clip 9 to rotate, thereby realizing the forward rotation of the air guide plate 4; when the drive rod 10 is retracted, the gear 17 and the two tooth structures 18 will perform reverse transmission, thereby realizing the reverse rotation of the air guide plate 4.

[0043] In any of the above examples, the extension and retraction of the drive rod 10 can be achieved by driving an ejection mechanism such as an electric cylinder, an oil cylinder, or a pneumatic cylinder. However, this does not effectively contribute to the compactness of the air conditioner's internal structure. In this regard, the present disclosure also provides a preferred solution, which will be discussed below.

[0044] See also Figure 6 , a mounting cavity 11 is further provided in the mounting rod 5, and the mounting rod 5 has a first side wall facing the air guide plate 4 and a second side wall facing the filter 3. The driving rod 10 is arranged on the first side wall so as to be elastically movable by a spring. For example, a mounting hole is provided on the first side wall, and the driving rod 10 can extend into the mounting cavity 11 from the mounting hole. In addition, the mounting cavity 11 is open at the end of the mounting rod 5, and a power rod 12 is also arranged in the mounting cavity 11 so as to be elastically movable along the axial direction, and a driving block 13 is provided on the side wall of the power rod 12 facing the driving rod 10. Among them, a driving inclined surface 14 is also provided on the side wall of the driving block 13, and the driving rod 10 abuts against the driving inclined surface 14 under the elastic force of the spring.

[0045] See also Figure 7 A driving plate 15 is further provided on the inner wall of the air outlet 2 , and a wavy driving surface 16 is provided on the side wall of the driving plate 15 . The end of the power rod 12 extending from the mounting rod 5 abuts against the driving surface 16 .

[0046] For example, a roller may be rotatably provided on the end of the mounting rod 5. When the mounting rod 5 moves, the mounting rod 5 is abutted by the driving surface 16 and is pushed back and forth in the axial direction, thereby driving the driving block 13 to continuously push the driving rod 10 to achieve the extension and retraction of the driving rod 10, and finally achieve the reciprocating sweeping of the air deflector 4.

[0047] For example, the driving surface 16 can be formed by connecting a plurality of driving units in sequence, each of which includes a plurality of connected crests and troughs. The following is an exemplary operation process of the present disclosure:

[0048] S1, in the initial state, the driving rod 10 and the power rod 12 are both in the initial position, and the air guide plate 4 remains in the vertical state;

[0049] S2, the mounting rod 5 moves to clean the filter 3; during this period, the end of the power rod 12 moves along the driving surface 16;

[0050] S201, when the power rod 12 moves to face the wave crest, the power rod 12 pushes out into the installation cavity 11, and drives the driving rod 10 to push out, causing the air guide plate 4 to rotate forward;

[0051] S202 , when the power rod 12 moves to be opposite to the trough, the power rod 12 is pushed out away from the side of the installation cavity 11 and drives the driving rod 10 to be retracted, and the air guide plate 4 is reversed.

[0052] In the example where two drive rods 10 are provided corresponding to the air guide plate 4, two drive blocks 13 may be provided on the side wall of the power rod 12, and the two drive blocks 13 correspond to the two drive rods 10 respectively. The difference is that the two drive inclined surfaces 14 on the two drive blocks 13 have opposite inclination directions. It can be imagined that in combination with this example in the above S2, when the power rod 12 is ejected into the installation cavity 11, one of the drive rods 10 will be ejected under the push of the drive block 13, and the other drive rod 10 will be retracted under the action of the elastic force; when the power rod 12 is ejected away from the side of the installation cavity 11, the two drive rods 10 will move in opposite directions again.

[0053] However, continuous air sweeping may not be desirable for users. In some cases, users prefer that the air deflector 4 maintain a constant air guide angle. To address this, the present disclosure further provides an electromagnet 19 on the mounting rod 5. When energized, the electromagnet 19 attracts the drive rod 10, thereby maintaining the relative stability of the drive rod 10. Furthermore, the drive block 13 is also adapted to be resilient, and it is particularly preferred that the spring constant of the spring (not shown) connected to the drive block 13 be greater than the spring constant of the spring connected to the drive rod 10.

[0054] When the user expects the air guide plate 4 to maintain the current air guide angle, the air conditioner controller can be energized by pressing a button on the air conditioner body 1 or using a wireless remote control to control the electromagnet 19. In this way, the drive rod 10 will maintain a constant ejection position to keep the air guide plate 4 in a constant deflection posture. At this time, the power rod 12 will still be ejected reciprocatingly under the drive of the drive surface 16, but because the drive rod 10 is fixed, the contact between the drive rod 10 and the drive block 13 will cause the drive block 13 to be ejected. When the drive rod 10 is not fixed, that is, when the air guide plate 4 is sweeping the air normally, due to the different spring coefficients of the two springs, the axial movement of the power rod 12 will drive the drive block 13 to eject the drive rod 10. This is because the spring on the drive rod 10 is more easily compressed.

[0055] For example, the cleaning member 6 is preferably arranged on the side wall of the power rod 12 away from the driving block 13. When the power rod 12 is reciprocating, the cleaning member 6 can clean the filter screen 3 in a direction different from the moving direction of the mounting rod 5, thereby improving the dust removal effect.

[0056] In a preferred embodiment, the cleaning member 6 is also adapted to be resilient, so that when the driving block 13 is ejected away from the driving rod 10, the driving block 13 pushes the cleaning member 6 further against the filter 3, for example, so that the cleaning member 6 can be inserted into the filter hole to achieve deeper dust removal of the filter 3. The cleaning member 6 can preferably be a bristle mounted on the connecting rod.

[0057] The foregoing description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Rather, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant field. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the appended claims.
