Detailed Implementation

[0020] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0022] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0023] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0024] In existing ventilation equipment, a sliding plate is slidably installed at the ventilation opening. When ventilation is needed, the sliding plate is controlled to slide and open the ventilation opening; when ventilation is not needed, the sliding plate is controlled to slide and close the ventilation opening. However, when the ventilation opening is open, the components at the air inlet end of the ventilation opening are easily exposed, which greatly reduces the aesthetics of the ventilation device. In addition, the complex structure and cumbersome control process of the ventilation device make it difficult to open and close the ventilation opening in a timely manner, resulting in a poor user experience.

[0025] This invention creatively provides a ventilation device, including a housing and a baffle plate, which are arranged front to back. The baffle plate is located on the air inlet side of a first air outlet and has a sealing part and a second air outlet. The baffle plate can be controlled to move forward relative to the housing, so that the sealing part and the first air outlet are in a closed contact state, ensuring a tight seal. The baffle plate can also be controlled to move backward relative to the housing, so that the sealing part and the first air outlet are in a separated state with the first air outlet open. Furthermore, the baffle plate can be controlled to rotate relative to the housing, adjusting the flow area of ​​air flowing through the second air outlet and the first air outlet. The ventilation device is aesthetically pleasing, the baffle plate has a short travel distance, it can achieve rapid ventilation, and the user experience is good.

[0026] <Shell and wind deflector> like Figure 1 , Figure 2a and Figure 2b As shown, this embodiment provides a ventilation device, including a housing 1 and a baffle plate 2, which are arranged front to back. The housing 1 has a first air outlet 111, with the air outlet side of the first air outlet 111 being the front side of the housing 1 and the air inlet side of the first air outlet 111 being the rear side of the housing 1. The baffle plate 2 is movably arranged on the air inlet side of the first air outlet 111. The baffle plate 2 has a sealing part 22 and a second air outlet 211, which are spaced apart from each other. The baffle plate 2 can be controlled to move back and forth and rotate relative to the housing 1. like Figure 4a and Figure 4b As shown, the baffle plate 2 can be controlled to move forward relative to the housing 1, so that the sealing part 22 and the first air outlet 111 can be in a contact state that closes the first air outlet 111. like Figure 5a , Figure 5b and Figure 5c As shown, the baffle plate 2 can be controlled to move backward relative to the housing 1, so that the sealing part 22 and the first air outlet 111 can be in a separated state with the first air outlet 111 open; then the baffle plate 2 can be controlled to rotate relative to the housing 1, so that the flow area of ​​air flowing through the second air outlet 211 and the first air outlet 111 can be adjusted. In summary, when the sealing part closes the first air outlet, it provides a tight seal, preventing foreign objects from entering the ventilation device and causing safety hazards. When the second air outlet connects with the first air outlet, ventilation is achieved with a large ventilation volume. The ventilation device is aesthetically pleasing, with a simple structure and control process. The short travel of the baffle plate allows for timely opening and closing of the ventilation openings, enabling rapid ventilation and providing a good user experience. It solves the problems of low aesthetic appeal, complex structure, and untimely opening and closing of ventilation openings in ventilation devices.

[0027] like Figure 3a As shown, to address the issues of poor aesthetics and low ventilation volume in ventilation devices, this embodiment proposes that the housing 1 has a first hollow structure 11, which forms multiple first air outlet holes 111; the baffle plate 2 has a second hollow structure 21, which forms multiple second air outlet holes 211; the number of first air outlet holes 111 is the same as the number of second air outlet holes 211, and the first air outlet holes 111 and second air outlet holes 211 correspond one-to-one; the hollow structure has good aesthetics, and the baffle plate 2 is hidden on the rear side of the housing 1, making it less likely to expose the internal components of the ventilation device; like Figure 5a , Figure 5b and Figure 5c As shown, when the baffle plate 2 moves backward and rotates relative to the housing 1, so that the first air outlet 111 and the second air outlet 211 are connected, the air inside the ventilation device is discharged through the second air outlet 211 and the first air outlet 111 in sequence; when the baffle plate 2 rotates relative to the housing 1, so that the first air outlet 111 and the second air outlet 211 are aligned, the air outlet resistance is small, the air outlet is smooth, and the air outlet volume is maximized.

[0028] Preferably, both the housing 1 and the baffle plate 2 are arc-shaped structures. Multiple rows of first air outlet groups are provided along the width direction of the housing 1, and the first air outlets 111 in each row of the first air outlet groups are spaced apart along the length direction of the housing 1. Multiple rows of second air outlet groups are provided along the width direction of the baffle plate 2, and the second air outlets 211 in each row of the second air outlet groups are spaced apart along the length direction of the baffle plate 2.

[0029] To address the issues of inadequate and untimely sealing when the first air outlet is closed, this embodiment proposes that the second hollow structure 21 be provided with multiple sealing parts 22, the number of sealing parts 22 being the same as the number of the first air outlets, and the sealing parts 22 corresponding one-to-one with the first air outlets 111; the distribution pattern of the sealing parts 22 on the baffle plate 2 is consistent with the distribution pattern of the first air outlets 111 on the housing 1; one sealing part 22 is arranged adjacent to one second air outlet 211; by controlling the baffle plate 2 to move forward relative to the housing 1, the sealing parts 22 promptly approach the first air outlets 111 and close the first air outlets 111.

[0030] Furthermore, the sealing part 22 is a sealing protrusion, which is formed on the side of the wind baffle 2 near the housing 1 and extends away from the wind baffle 2. When the sealing part 22 closes the first air outlet 111, the sealing part 22 is embedded in the corresponding first air outlet 111 and closes the first air outlet 111; the seal is tight, preventing foreign objects from entering the ventilation equipment.

[0031] <Connector> like Figure 3b and Figure 3c As shown, in response to the problem of unstable movement of the wind deflector 2, this embodiment proposes that the ventilation device also includes a connector 31. The wind deflector 2 and the connector 31 are slidably engaged together, and the wind deflector 2 can be controlled to slide relative to the connector 31, so that the wind deflector 2 moves forward relative to the housing 1, thereby sealing the first air outlet 111 with the sealing part 22, or the wind deflector 2 moves backward relative to the housing 1, thereby opening the first air outlet 111 with the sealing part 22. Specifically, the connector 31 has a first groove 311, and the end of the wind deflector 2 is provided with a first sliding member 23. The first sliding member 23 is integrally formed with the wind deflector 2 or detachably connected; the first sliding member 23 is embedded in the first groove 311; the ventilation device also includes a first drive motor 45 and a first transmission mechanism, and the first drive mechanism includes a first gear 41 and a first rack 42. The first gear 41 is mounted on the connector 31, and the first rack 42 is mounted on the first sliding member 23, with the first gear 41 meshing with the first rack 42. The first drive motor 45 is connected to the first gear 41, driving the first gear 41 to rotate. The first gear 41 drives the first rack 42 to move, and the first sliding member 23 slides along the first sliding groove 311, thereby causing the wind deflector 2 to move back and forth relative to the housing 1; or The first gear 41 is disposed on the first sliding member 23, and the first rack 42 is disposed on the connecting member 31. The first gear 41 meshes with the first rack 42. The first gear 41 drives the first rack 42 to move, and the first sliding member 23 slides along the first sliding groove 311, thereby causing the wind deflector 2 to move back and forth relative to the housing 1. Preferably, the first gear 41 is disposed on the connecting member 31, and the first rack 42 is disposed on the first sliding member 23; specifically, the first gear 41 is disposed in the first sliding groove 311, and the first sliding member 23 includes two members, which are spaced apart on both sides of the first gear 41 in the radial direction, and the two members 23 are slidably engaged with the two side walls of the first sliding groove 311 respectively; a clearance space is formed between the two members 23, and the first gear 41 is disposed in the clearance space; the first rack 42 is disposed on one of the first sliding members 23 and is disposed close to the first gear 41. With a simple structure, reliable connection, stable and rapid movement, it achieves rapid ventilation and rapid closure of the first air outlet.

[0032] <Fixed base> like Figure 3b and Figure 3c As shown, to address the issues of limited freedom of movement of the baffle 2 and the inability to adjust the airflow of the ventilation device, this embodiment proposes that the ventilation device further includes a fixed base 32, on which the housing 1 can be fixed; the connecting member 31 is slidably mounted on the fixed base 32, and the connecting member 31 can be controlled to rotate relative to the fixed base 32, thereby causing the baffle 2 to rotate relative to the housing 1, which can make the first air outlet 111 and the second air outlet 211 aligned or staggered; when the first air outlet 111 and the second air outlet 211 are aligned, the airflow is at its maximum. By controlling the staggered distance between the first air outlet 111 and the second air outlet 211, the flow area of ​​air flowing through the second air outlet 211 and the first air outlet 111 can be adjusted, thereby regulating the airflow.

[0033] Furthermore, the fixed base 32 is formed with a second sliding groove 321, and the connecting member 31 is provided with a second sliding member 312, which is embedded in the second sliding groove 321; the ventilation device also includes a second drive motor and a second transmission mechanism, the second transmission mechanism including a second gear 43 and a second rack 44; The second gear 43 is mounted on the fixed base 32, and the second rack 44 is mounted on the connecting member 31. The second gear 43 meshes with the second rack 44. The second drive motor is connected to the second gear 43, driving the second gear 43 to rotate. The second gear 43 drives the second rack 44 to move, and the second sliding member 312 slides along the second sliding groove 321. Consequently, the connecting member 31 and the windshield 2 slide synchronously relative to the fixed base 32. The second gear 43 is mounted on the connector 31, and the second rack 44 is mounted on the fixed seat 32. The second gear 43 meshes with the second rack 44. The second gear 43 drives the second rack 44 to move. The second sliding member 312 slides along the second sliding groove 321. The connector 31 slides relative to the fixed seat 32, and the wind deflector 2 slides relative to the housing 1.

[0034] Preferably, the second gear 43 is mounted on the fixed base 32, and the second rack 44 is mounted on the connecting member 31; the housing 1, the wind baffle 2, the second rack 44, the second slide groove 321, and the second sliding member 312 are all arc-shaped structures; the second gear 43 drives the second rack 44 to move, the second sliding member 312 slides along the second slide groove 321, the connecting member 31 rotates relative to the fixed base 32, and then the wind baffle 2 rotates relative to the housing 1, so that the first air outlet 111 and the second air outlet 211 are aligned or staggered; With a simple structure, reliable connection, stable and rapid movement, the wind deflector 2 has increased degrees of freedom of movement, and the air volume can be adjusted according to the alignment degree of the first air outlet 111 and the second air outlet 211.

[0035] <Air choke strip> To address the issue that excessive airflow can cause user discomfort, this embodiment proposes that a wind-blocking strip 12 be provided on the end face of the housing 1 near the wind baffle 2. The wind-blocking strip 12 is correspondingly provided with the first air outlet 111 and is used to disperse the air flowing from the second air outlet 211 to the first air outlet 111. Combined with the wind baffle 2, it can reduce the wind speed and achieve a gentle breeze. Furthermore, the air baffle 12 can be a long air baffle extending along the length direction of the housing 1, and there are multiple long air baffles, each of which is disposed between two adjacent rows of first air outlet holes 111; or a short air baffle adapted to the size of the first air outlet holes 111, and there are multiple short air baffles, with one short air baffle disposed between every two adjacent first air outlet holes 111 along the width direction of the housing 1.

[0036] <Cabinet-type air conditioner> This embodiment also provides a cabinet air conditioner, which includes an indoor unit and a ventilation device as described in any of the above embodiments. The indoor unit has an air outlet, and the ventilation device is disposed at the air outlet. The sliding door panel with transmission mechanism has been eliminated, and the decorative panel and traditional door panel are integrated into one design with a hollow structure to enhance the overall aesthetics of the cabinet air conditioner.

[0037] Furthermore, the casing 1 forms the decorative panel of the indoor unit, and the decorative panel and the wind deflector 2 extend along the height direction of the cabinet air conditioner.

[0038] In addition, the cabinet air conditioner also includes a detection component 46, a controller, and fan blades; the first drive motor 45 and the second drive motor are both electrically connected to the controller; the detection component 46 is electrically connected to the controller and is used to detect whether there is a person in the direction of the air outlet and transmit the detection signal to the controller. The controller is used to control the first drive motor 45 and the second drive motor to move according to the detection signal, so that the baffle 2 moves relative to the housing 1. By controlling the operation of the first drive motor 45, the baffle 2 moves towards the air inlet side of the first air outlet 111 and moves backward relative to the housing 1, thereby opening the first air outlet 111 with the sealing part 22; then, the second drive motor is controlled to rotate the baffle 2 relative to the housing 1. When the first air outlet 111 and the second air outlet 211 are aligned, the first air outlet 111 is fully open; when there is a person in front of the air outlet of the first air outlet 111, the detection element 46 receives the signal and transmits it to the controller; the controller controls the operation of the second drive motor, so that the first air outlet 111 and the second air outlet 211 are staggered, the baffle 2 begins to block the wind, and when the cold air passes through the baffle 2 and reaches the housing 1, the wind deflector 12 disperses the cold air, and then passes through the first air outlet 111 and blows on the human body, at which time the human body feels the feeling of a gentle breeze. When a person leaves the air outlet side of the first air outlet 111, the detection element 46 receives a signal and transmits it to the controller; the controller controls the second drive motor to run, so that the first air outlet 111 and the second air outlet 211 are aligned, and the first air outlet 111 is in a fully open state.

[0039] Specifically, when the ventilation device of this embodiment is turned on, the first gear 41 drives the first rack 42 to move, causing the baffle 2 to extend and retract relative to the housing 1. After the extension and retraction is completed, the second gear 43 drives the second rack 44 to rotate, causing the baffle 2 to rotate to the left. At this time, the first air outlet 111 is fully open. Then, the fan blades are controlled to rotate and the air is ventilated. It only takes about 8 seconds to shorten the movement stroke of the ventilation device and achieve rapid air ventilation. The second gear 43 drives the second rack 44 to rotate, causing the baffle 2 to rotate to the right, which can block the first air outlet 111 and prevent cold air from blowing directly on the human body.
