Description

Technical Field

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

[0002] Air conditioning, or air conditioner, refers to equipment that uses artificial means to adjust and control parameters such as temperature, humidity, and flow rate 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 utilizing 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 the air conditioner is not cleaned for a long time, a lot of dust will accumulate inside the air conditioner and breed bacteria. When the air conditioner is working, a large number of bacteria will enter the room with the air conditioning wind. Living and working in such an environment for a long time will easily make you feel dizzy and weak, and cause colds, fevers and other diseases. We call it "air conditioning disease". Therefore, it is necessary to remove the dust inside the air conditioner regularly.

[0004] There is a technical solution in the prior art for cleaning the filter at the air outlet of the air conditioner by using a movable brush rod, but it is impossible 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.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 7 As shown, an air conditioning unit that is easy to remove dust includes an air conditioning body 1, an air outlet 2 is configured on the top of the air conditioning body 1, and an air guide plate 4 and a filter 3 are sequentially arranged in the air outlet 2 along the depth direction. The filter 3 is used to filter the airflow blown out by the air conditioner; the air guide plate 4 can rotate to guide the airflow in the desired direction, for example, the axis of the air guide plate 4 can extend in the horizontal direction, so that the airflow can change the flow direction up and down. Generally speaking, the air guide plate 4 can adjust the guide angle by manual or electric rotation.

[0031] A mounting rod 5 is movably disposed between the filter screen 3 and the air guide plate 4 in the air outlet 2. For example, the mounting rod 5 can be moved by the transfer of a screw transfer mechanism (not shown). The screw transfer mechanism is a prior art, and its working principle and structure are not described in detail in this disclosure. A cleaning member 6 facing the side of the filter screen 3 is disposed on the mounting rod 5. For example, the cleaning member 6 can abut against the filter screen 3. In this way, during the movement of the mounting rod 5, the cleaning member 6 can clean the filter screen 3.

[0032] In the present disclosure, the mounting rod 5 is particularly adapted to move along the length direction of the air guide plate 4, that is, the mounting direction of the lead screw is parallel to the air guide plate 4. In addition, a cleaning sleeve 7 is sleeved on the air guide plate 4, and is adapted to drive the cleaning sleeve 7 to move along the air guide plate 4 through the movement of the mounting rod 5, thereby achieving synchronous cleaning of the air guide plate 4 by the cleaning sleeve 7. The driving method between the mounting rod 5 and the cleaning sleeve 7 will be elaborated in detail below in combination with several embodiments.

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

[0034] In a possible approach, the mounting rod 5 and the cleaning sleeve 7 can also be connected by magnetic attraction (not shown). When the mounting rod 5 moves along the length direction of the air guide plate 4, the cleaning sleeve 7 can move on the air guide plate 4 seemingly suspended under the magnetic attraction to achieve cleaning. For example, the generation and disappearance of the magnetic force can also be controlled to achieve the unlocking and re-engagement of the cleaning sleeve 7 and the mounting rod 5. Alternatively, the magnitude of the magnetic force can be optimized so that the cleaning sleeve 7 can rotate with the rotation of the air guide plate 4 while being driven by the mounting rod 5 to move along the air guide plate 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 guide plate 4 to rotate.

[0036] Although the movement of the mounting rod 5 and the cleaning sleeve 7 and the rotation of the air guide plate 4 do not interfere with each other in the present disclosure, when the air guide plate 4 is rotated by electric means, at least two actuators need to be arranged 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 guide plate 4. This may eventually lead to an increase in the size of the air conditioner.

[0037] In view of the above technical problem, in the present disclosure, a retractable driving rod 10 is further provided on the side wall of the mounting rod 5, and the air guide plate 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. And the driving rod 10 is set to one corresponding 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 out 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 driving rods 10 and two wind guide rods may be provided correspondingly, and the axial projections of the two driving rods 10 are distributed on both sides of the rotation axis of the wind guide plate 4. In this example, the rotating shaft on the wind guide plate 4 does not need to be connected to a torsion spring, and the forward and reverse rotation of the wind guide plate 4 is achieved by respectively pushing out and retracting the two driving rods 10.

[0040] It is understandable that, for example, Figure 4 As shown in FIG, when the air guide plate 4 needs to rotate clockwise, the driving rod 10 at the top can be controlled to be pushed out and the driving rod 10 at the bottom can be retracted, thereby pushing the air guide plate 4 to rotate clockwise; similarly, when the air guide plate 4 needs to rotate counterclockwise, the driving rod 10 at the bottom can be controlled to be pushed out and the driving rod 10 at the top can be retracted. When both driving rods 10 are in the initial position, the air guide plate 4 remains in a vertical state 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 fan-shaped, and the center of the clip 9 coincides with the rotation axis of the air guide plate 4. In addition, a gear 17 is rotatably arranged in the clip seat 8, and a toothed structure 18 is arranged on the side wall of the clip 9 and the side wall of the driving rod 10. The gear 17 is meshed with two toothed structures 18 at the same time.

[0042] It can be imagined that in this example, when the driving rod 10 is pushed out, the driving 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 driving 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 driving rod 10 can be achieved by driving an ejection mechanism such as an electric cylinder, an oil cylinder or a gas cylinder. However, this does not contribute well to the compactness of the internal structure of the air conditioner. In this regard, the present disclosure also provides a preferred solution to be described below.

[0044] See also Figure 6 , a mounting cavity 11 is also 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 screen 3. The driving rod 10 is movably provided on the first side wall 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 movably provided in the axial direction in the mounting cavity 11, 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 also 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 out of 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 will be pushed out reciprocatingly along the axial direction under the contact of the driving surface 16, 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 realize the reciprocating sweeping of the wind guide plate 4.

[0047] For example, the driving surface 16 can be formed by connecting a plurality of driving units in sequence, and each driving unit includes a plurality of connected wave crests and wave 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 a vertical state;

[0049] S2, the installation rod 5 moves to clean the filter screen 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 be opposite to the wave crest, the power rod 12 is pushed out into the installation cavity 11, and drives the driving rod 10 to be pushed out, and the air guide plate 4 rotates 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] Among them, in the example where two drive rods 10 are provided corresponding to the air guide plate 4, two drive blocks 13 may be specifically 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 slopes 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.

[0053] However, continuous wind sweeping may not be desired by the user. In some cases, the user expects the wind deflector 4 to maintain a constant wind deflection angle. In this regard, the present disclosure further provides an electromagnet 19 on the mounting rod 5. When the electromagnet 19 is energized, it can adsorb the drive rod 10, thereby keeping the drive rod 10 relatively fixed. In addition, the drive block 13 is also adapted to be elastically arranged, and it is particularly preferred that the spring coefficient of the spring (not shown) connected to the drive block 13 is greater than the spring coefficient 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 control the electromagnet 19 to energize by pressing a button on the air conditioner body 1 or using a wireless remote control, so that 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 wind normally, due to the different stiffness 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, because the spring on the drive rod 10 is easier to be compressed.

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

[0056] In a preferred example, the cleaning member 6 is also adapted to be elastically arranged, so that when the driving block 13 is ejected away from the side of the driving rod 10, the driving block 13 will eject the cleaning member 6 further against the filter 3, for example, 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 brush installed on the connecting rod.

[0057] The above is only 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 regarded as excluding other embodiments, but 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 the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art shall not deviate from the spirit and scope of the present invention, and shall be within the scope of protection of the claims attached to the present invention.
