Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to an adaptive pressure regulating zero-wind-sensing air guide damper and an air conditioner. Background Technology

[0002] In related technologies, to avoid direct airflow, air conditioners are generally set with a windless mode. In windless mode or zero-wind-feel mode, the entire room is in a windless state.

[0003] Currently, the air duct openings in the zero-wind mode of air conditioners cannot be changed once the design is finalized. However, actual user scenarios are complex, resulting in certain design flaws.

[0004] 1. When users use the high-airflow zero-wind mode, they focus on the cooling effect. If the cross-section of the through hole is too small, it will result in insufficient airflow, leading to a significant reduction in cooling capacity and poor performance.

[0005] 2. When users use the low fan speed setting with zero wind, they focus on the absence of wind. If the cross-section of the through-hole is too large, the cold air will blow directly on people, resulting in a poor user experience. Summary of the Invention

[0006] In view of this, the present invention aims to propose an adaptive pressure-regulating zero-wind-feel air guide damper and air conditioner, which can adaptively adjust the ventilation area of ​​the air guide damper according to the fan speed. When the user uses a low fan speed setting, the air guide damper through hole automatically shrinks, and only the air is blown out through the middle through hole, improving the zero-wind-feel user experience at low fan speeds. When the user uses a high fan speed setting, the air guide damper is subjected to increased wind pressure, opening the auxiliary ventilation hole to increase the air volume passing through and improve the actual working effect of the air conditioner.

[0007] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0008] An adaptive pressure-regulating zero-wind-feel damper includes:

[0009] An air guide plate, wherein a first ventilation hole is provided on the air guide plate;

[0010] A sealing end plate is detachably connected to the air guide plate, and an air outlet groove is provided on the sealing end plate;

[0011] A pressure regulating plate is disposed in the space formed by the air guide plate and the sealing end plate, and a second ventilation hole is provided on the pressure regulating plate;

[0012] The pressure regulating device can drive the pressure regulating plate to move relative to the air guide plate under the action of the air pressure on the air inlet side, thereby adjusting the ventilation area of ​​the second ventilation hole on the pressure regulating plate.

[0013] The adaptive pressure-regulating zero-wind-feel air guide damper of the present invention has a reasonable and ingenious design of the air guide damper structure. Under the action of different wind pressure settings set by the user, the ventilation area of ​​the air guide damper is automatically adjusted. While achieving zero wind feel, the attenuation of heat exchange air force is reduced, thereby improving the cooling comfort.

[0014] Furthermore, the voltage regulating plate includes:

[0015] The second substrate can move along a straight line under the action of the voltage regulating device;

[0016] The second ventilation hole includes:

[0017] A first through hole is disposed on the second substrate and communicates with a first ventilation hole;

[0018] The second through hole is disposed on the second substrate and can be connected to or blocked from the first ventilation hole under the action of the pressure regulating device.

[0019] This configuration allows the pressure regulating plate to move in a straight line under the action of the pressure regulating device. The first through hole is set as a normally open through hole that is always connected to the first ventilation hole, and the second through hole is an auxiliary ventilation hole that is gradually opened after the pressure regulating plate moves. This realizes the change of ventilation area on the pressure regulating plate when it moves, reduces the pressure loss of the air outlet in the high air pressure mode, and ensures the effect of high air volume and no wind feeling when the air is ventilated.

[0020] Furthermore, the diameter of the second through hole is larger than the diameter of the first through hole, and the second through hole includes at least two through holes with different diameters.

[0021] This setting further improves the effect of airflow without a noticeable draft even at high air volume.

[0022] Furthermore, the voltage regulating plate also includes:

[0023] A pressure regulating boss is provided on the surface of the second substrate near the air guide plate. The first through hole passes through the pressure regulating boss. A pressure regulating curved surface is provided on the pressure regulating boss. The pressure regulating curved surface can make sealing contact with the inner surface of the first ventilation hole.

[0024] This setting ensures a windless airflow effect even at low and high airflow rates.

[0025] Furthermore, the voltage regulating device includes:

[0026] The pressure regulating spring has one end fixedly connected to the pressure regulating plate and the other end in contact with the air guide plate and / or the sealing end plate;

[0027] The limiting post can penetrate the pressure regulating plate, and the pressure regulating plate can slide linearly relative to the limiting post.

[0028] This setting allows the zero-wind-feel air deflector to continuously adjust the ventilation surface based on the air volume and speed on the air inlet side during actual use. The ventilation area in zero-wind-feel mode is adaptively adjusted according to the user-set wind speed. It is not manually adjusted, but automatically adjusts the ventilation area of ​​the air deflector, achieving zero wind while reducing the attenuation of working capacity and improving working comfort.

[0029] Furthermore, the pressure regulating spring is disposed between the pressure regulating plate and the sealing end plate, the limiting post is disposed on the sealing end plate, a limiting hole is provided on the pressure regulating plate, and the other end of the limiting post passes through the limiting hole and extends into the positioning hole on the air guide plate.

[0030] This design provides a specific structure for a pressure regulating device, ensuring the reliability of the tight connection between the pressure regulating plate and the air guide plate under low airflow conditions, further improving the effect of windless airflow under low airflow conditions and the effect of windless airflow under adaptive high airflow conditions.

[0031] Furthermore, the first ventilation hole is designed with a gradually increasing cross-section from top to bottom.

[0032] The conical first ventilation hole structure not only achieves a low-volume, windless airflow effect, but also allows the pressure regulating plate to move away from the guide plate as the airflow on the inlet side gradually increases. At this time, the gap between the pressure regulating surface and the inner surface of the first ventilation hole gradually increases, so that the larger airflow passing through the guide plate can gently push the pressure regulating plate to one side, avoiding violent movement of the pressure regulating plate and ensuring a windless airflow effect.

[0033] This setting allows for variable cross-section design of the pressure regulating surface according to air volume requirements, ensuring that the air guide damper adapts to the effect of windless airflow under low and high air volume conditions.

[0034] Furthermore, a second mounting groove is provided on the side of the sealing end plate near the pressure regulating plate, and a first mounting groove is provided on the side of the pressure regulating plate near the sealing end plate. The two ends of the pressure regulating spring are respectively located in the first mounting groove and the second mounting groove.

[0035] Furthermore, the air guide plate includes a first base plate, the first ventilation hole is disposed on the first base plate, a frame plate is disposed around the first base plate, a positioning plate is disposed on the side plates on opposite sides of the frame plate, a slot is disposed on the end plate frame of the sealing end plate, the positioning plate is inserted into the slot, and a rotating shaft is disposed on the positioning plate.

[0036] This setting further improves the reliability and stability of the zero-wind mode ventilation area adaptively adjusting according to the user-set wind speed. By rationally setting the specific structure and position of the pressure regulating device, it can automatically adjust the ventilation area of ​​the air guide, achieving zero wind while reducing the attenuation of working capacity and improving working comfort.

[0037] Compared with existing technologies, the adaptive pressure regulating zero-wind-sensing air guide damper of the present invention has the following advantages:

[0038] (1) The adaptive pressure-regulating zero-wind-feel air guide door of the present invention can adaptively adjust the ventilation area of ​​the air guide door according to the wind speed. When the user uses a low air volume setting, the air outlet area of ​​the air guide door through hole is automatically reduced, and only the first through hole blows out, improving the zero-wind-feel user experience at low air volume. When the user uses a high air volume setting, the air guide door is subjected to increased wind pressure, opening the auxiliary ventilation hole and the second through hole is adaptively opened, increasing the air volume passing through, improving the actual working effect of the air conditioner, and more closely matching the user's actual usage scenario, satisfying the adaptive adjustment in the zero-wind-feel mode under low and high air volume.

[0039] (2) The adaptive pressure regulating zero-wind-feel air guide door of the present invention has a clever structure and does not require an additional drive structure. It automatically adjusts the ventilation area of ​​the air guide door according to the wind speed set by the user, so as to realize the zero-wind-feel mode ventilation area adaptively adjusted according to the wind speed set by the user. It works reliably and improves the user experience.

[0040] Another object of the present invention is to provide an air conditioner, including an indoor unit, wherein an adaptive pressure regulating zero-wind-sensing air guide damper as described above is provided at the air outlet of the indoor unit.

[0041] The advantages of the air conditioner and the aforementioned adaptive pressure regulating zero-wind-feel air guide damper compared to the prior art are the same, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0061] To make the technical means and objectives and effects of the present invention easier to understand, the embodiments of the present invention will be described in detail below with reference to specific illustrations.

[0062] Example 1

[0063] like Figures 1-16 As shown, this invention discloses an adaptive pressure-regulating zero-wind-feel air guide damper, comprising:

[0064] Air guide plate 1, on which a first ventilation hole 7 is provided;

[0065] The sealing end plate 4 is detachably connected to the air guide plate 1, and an air outlet groove 403 is provided on the sealing end plate 4.

[0066] A pressure regulating plate 2 is disposed in the space formed by the air guide plate 1 and the sealing end plate 4, and a second ventilation hole 8 is provided on the pressure regulating plate 2;

[0067] The pressure regulating device 3 can drive the pressure regulating plate 2 to move relative to the air guide plate 1 under the action of the air pressure on the air inlet side, and adjust the ventilation area of ​​the second ventilation hole 8 on the pressure regulating plate 2.

[0068] The adaptive pressure-regulating zero-wind-feel air guide door of the present invention achieves windless airflow from the air conditioner through the first ventilation hole 7 on the air guide plate 1, the second ventilation hole 8 on the pressure regulating plate 2, and the air outlet groove 403 on the sealing end plate 4. In use, the air guide door is placed at the air outlet of the air conditioner, and the air guide plate 1 is the air inlet side of the air guide door. When the air volume and air velocity are low, the pressure on the air inlet side is low. At this time, the user focuses on the windless feeling. The pressure regulating device 3 presses the pressure regulating plate 2 against the air guide plate 1. The first ventilation hole 7 on the air guide plate 1 is connected to some of the second ventilation holes 8 on the pressure regulating plate 2 to achieve windless airflow at low air volume. As the air volume and air velocity increase, the pressure on the air inlet side increases. Under the action of the air pressure and the pressure regulating device 3, the pressure regulating plate 2 can move relative to the air guide plate 1. At this time, more of the second ventilation holes 8 on the pressure regulating plate 2 are opened, increasing the ventilation area on the pressure regulating plate 2, reducing the pressure loss at the air outlet, and achieving windless airflow at high air volume.

[0069] The adaptive pressure-regulating zero-wind-feel air guide damper of the present invention has a reasonable and ingenious design of the air guide damper structure. Under the action of different wind pressure settings set by the user, the ventilation area of ​​the air guide damper is automatically adjusted. While achieving zero wind feel, the attenuation of heat exchange air force is reduced, thereby improving the cooling comfort.

[0070] As a preferred example of the present invention, the pressure regulating plate 2 includes:

[0071] The second substrate 201 can move along a straight line under the action of the voltage regulating device 3;

[0072] The second ventilation hole 8 includes:

[0073] The first through hole 801 is disposed on the second substrate 201 and communicates with the first ventilation hole 7;

[0074] The second through hole 802 is disposed on the second substrate 201, and can be connected to or blocked from the first ventilation hole 7 under the action of the pressure regulating device 3.

[0075] This configuration allows the pressure regulating plate 2 to move in a straight line under the action of the pressure regulating device 3. The first through hole 801 is set as a normally open through hole that is always connected to the first ventilation hole 7, and the second through hole 802 is an auxiliary ventilation hole that is gradually opened after the pressure regulating plate 2 moves. This achieves the change of ventilation area on the pressure regulating plate 2 when it moves, reduces the pressure loss of the air outlet in the high air pressure mode, and ensures the effect of high air volume and no wind feeling when the air is ventilated.

[0076] Preferably, the diameter of the second through hole 802 is larger than the diameter of the first through hole 801, and the second through hole 802 may include at least two through holes with different diameters.

[0077] This setting further improves the effect of airflow without a noticeable draft even at high air volume.

[0078] As a preferred example of the present invention, the pressure regulating plate 2 further includes:

[0079] A pressure regulating boss 9 is disposed on the surface of the second substrate 201 near the air guide plate 1. The first through hole 801 passes through the pressure regulating boss 9. A pressure regulating curved surface 10 is disposed on the pressure regulating boss 9. The pressure regulating curved surface 10 can make sealed contact with the inner surface of the first ventilation hole 7.

[0080] This configuration ensures that when the air volume and velocity are low, the pressure on the inlet side is low, and the pressure regulating device 3 presses the pressure regulating plate 2 against the air guide plate 1. At this time, the second through hole 802 is fully closed, leaving only the first through hole 801 connected to the first ventilation hole 7 for air outlet. Figure 11 As shown, this ensures a windless airflow effect even at low and high air volumes.

[0081] As a preferred example of the present invention, the first ventilation hole 7 is arranged with a gradually increasing cross-section from top to bottom. Preferably, the first ventilation hole 7 has a standard conical structure or an arc-shaped conical structure with a gradually increasing cross-section. This arrangement increases the ventilable cross-sectional area and reduces pressure loss at the air outlet as the air pressure on the air inlet side increases.

[0082] Preferably, as an example of the present invention, the pressure regulating surface 10 is a standard conical surface, or the pressure regulating surface 10 is an arc-shaped conical surface. The inner surface of the first ventilation hole 7 is located on the air guide plate 1 near the inner side of the pressure regulating plate 2, indicating that the inner surface of the first ventilation hole 7 is fitted with the pressure regulating surface 10 to achieve a seal between the pressure regulating surface 10 and the inner surface of the first ventilation hole 7 when the pressure regulating plate 2 is pressed against the air guide plate 1.

[0083] When the pressure regulating device 3 presses the pressure regulating plate 2 against the air guide plate 1, the air volume on the inlet side is relatively small. Through the structure of the cone-shaped first ventilation hole 7, on the one hand, it satisfies the air outlet effect of low air volume without wind. At the same time, as the air volume on the inlet side gradually increases, the pressure regulating plate 2 moves away from the air guide plate 1. At this time, the gap between the pressure regulating curved surface 10 and the inner surface of the first ventilation hole 7 gradually increases, so that the larger air volume passing through the air guide plate 1 can gently push the pressure regulating plate 2 to one side, avoiding violent movement of the pressure regulating plate 2, reducing the pressure loss of the air outlet, and ensuring the air outlet effect without wind.

[0084] This setting allows for variable cross-section design of the pressure regulating surface 10 according to air volume requirements, ensuring that the air guide damper adapts to the effect of windless airflow under low and high air volume conditions.

[0085] As a preferred example of the present invention, the voltage regulating device 3 includes:

[0086] The pressure regulating spring has one end fixedly connected to the pressure regulating plate 2, and the other end in contact with the air guide plate 1 and / or the sealing end plate 4;

[0087] The limiting post 13 can penetrate the pressure regulating plate 2, and the pressure regulating plate 2 can slide linearly relative to the limiting post 13.

[0088] When the air volume and air velocity are low, the pressure on the air inlet side is low. Under the action of the pressure regulating spring, the pressure regulating plate 2 is in close contact with the air guide plate 1. At this time, only the first through hole 801 on the pressure regulating plate 2 provides ventilation, and the air volume is small, which satisfies the requirement of low air volume and no wind sensation when air is supplied. As the air volume gradually increases, the pressure on the air inlet side also gradually increases. The air pressure overcomes the elastic force of the pressure regulating spring, causing the pressure regulating plate 2 to move away from the air guide plate 1. Under the action of the limiting column 13, the pressure regulating plate 2 moves in a straight line. At this time, the second through hole 802 is opened, which is equivalent to opening the auxiliary ventilation hole, increasing the air volume and improving the actual working effect of the air conditioner.

[0089] This setting allows the zero-wind-feel air deflector to continuously adjust the ventilation surface based on the air volume and speed on the air inlet side during actual use. The ventilation area in zero-wind-feel mode is adaptively adjusted according to the user-set wind speed. It is not manually adjusted, but automatically adjusts the ventilation area of ​​the air deflector, achieving zero wind while reducing the attenuation of working capacity and improving working comfort.

[0090] As a specific example of the present invention, the pressure regulating spring is disposed between the pressure regulating plate 2 and the sealing end plate 4, the limiting post 13 is disposed on the sealing end plate 4, the pressure regulating plate 2 is provided with a limiting hole 12, and the other end of the limiting post 13 passes through the limiting hole 12 and extends into the positioning hole 6 on the air guide plate 1.

[0091] This setting provides a specific configuration structure for the pressure regulating device 3, ensuring the reliability of the tight connection between the pressure regulating plate 2 and the air guide plate 1 under low airflow conditions.

[0092] As a specific example of the present invention, a second mounting groove 14 is provided on the side of the sealing end plate 4 near the pressure regulating plate 2, and a first mounting groove 11 is provided on the side of the pressure regulating plate 2 near the sealing end plate 4. The two ends of the pressure regulating spring are respectively located in the first mounting groove 11 and the second mounting groove 14.

[0093] This design ensures the stability and reliability of the pressure regulating spring as it moves along the pressure regulating plate 2.

[0094] Preferably, the limiting post 13 is disposed in the second mounting groove 14, the limiting hole 12 communicates with the first mounting groove 11, and the pressure adjusting spring is sleeved on the limiting post 13.

[0095] As a preferred example of the present invention, the number and position of the pressure regulating springs can be adjusted according to the actual design, and are not limited to the positions and numbers shown in the figure.

[0096] This setting further improves the reliability and stability of the ventilation area in zero-wind mode, which is adaptively adjusted according to the user-set wind speed. The specific structure and position of the pressure regulating device 3 are reasonably set, which can automatically adjust the ventilation area of ​​the air guide door, thereby reducing the attenuation of working capacity and improving working comfort while achieving zero wind.

[0097] As a preferred example of the present invention, the air guide plate 1 includes a first base plate 101, the first ventilation hole 7 is disposed on the first base plate 101, a frame plate 102 is disposed around the first base plate 101, a positioning plate 103 is disposed on the side plates on opposite sides of the frame plate 102, and a slot 402 is disposed on the end plate frame 401 of the sealing end plate 4, and the positioning plate 103 is inserted into the slot 402.

[0098] As a preferred example of the present invention, a rotating shaft 5 is provided on the positioning plate 103. In this embodiment, the zero-wind-sensing air guide damper is installed at the air outlet of the indoor unit via the rotating shaft 5.

[0099] This design allows the integrated zero-wind-feel air deflector and indoor unit to rotate as a unit under the action of the drive device, achieving reliable operation in zero-wind-feel mode.

[0100] In this embodiment, the zero-wind-feel air guide damper with adaptive pressure regulation described in this invention can adaptively adjust the ventilation area of ​​the air guide damper according to the airflow setting. When the user uses a low airflow setting, the air outlet area of ​​the air guide damper through hole automatically shrinks, and air is blown out only through the first through hole 801, improving the zero-wind-feel user experience at low airflow. When the user uses a high airflow setting, the air pressure of the air guide damper increases, opening the auxiliary ventilation hole, and the second through hole 802 is adaptively opened, increasing the airflow and improving the actual working effect of the air conditioner. This is closer to the user's actual usage scenario and meets the adaptive adjustment in zero-wind-feel mode under low and high airflow conditions.

[0101] The adaptive pressure-regulating zero-wind-feel air guide damper of this invention has an ingenious structure that does not require an additional drive structure. It automatically adjusts the ventilation area of ​​the air guide damper according to the wind speed set by the user, so as to achieve the purpose of adaptive adjustment of the ventilation area in zero-wind-feel mode according to the wind speed set by the user. It is reliable in operation and improves the user experience.
