Description

TECHNICAL FIELD

[0001] The present application relates to the air conditioning technical field, and in particular, relates to an air conditioner and a control method thereof. BACKGROUND

[0002] When the air conditioner directly blows air to the user through the air outlet, the speed of the air flow is large, and the cold or hot air directly blows to the user, which easily causes the user to be uncomfortable. Therefore, the traditional air conditioner usually opens air outlet micro-holes on the air deflector or the louver, and uses the air outlet micro-holes to reduce the speed of the air flow. However, the air outlet micro-holes have large resistance to the air flow, which leads to a decrease in the air volume, and further leads to a decrease in the cooling or heating capacity of the air conditioner, so that the air conditioner has poor air outlet comfort in the windless mode. SUMMARY

[0003] The problem solved by the present application is that the existing air outlet micro-holes have large resistance to the air flow, so that the air conditioner has poor air outlet comfort in the windless mode.

[0004] To solve the above problem, in a first aspect, the present application provides an air conditioner, which comprises:

[0005] a shell, which is provided with an air outlet;

[0006] an upper air deflector, which is rotatably installed on the upper edge of the air outlet, and is provided with a first inclined groove, the first inclined groove extends along the length direction of the upper air deflector, and the first inclined groove penetrates through the thickness direction of the upper air deflector;

[0007] a lower air deflector, which is rotatably installed on the lower edge of the air outlet, and is provided with a second inclined groove, the second inclined groove extends along the length direction of the lower air deflector, and the second inclined groove penetrates through the thickness direction of the lower air deflector;

[0008] two air baffles, which are respectively detachably installed on the upper air deflector and the lower air deflector, and are used for respectively shielding the first inclined groove and the second inclined groove.

[0009] The air conditioner provided by the present embodiment has the following beneficial effects:

[0010] 1. By respectively opening the first inclined groove and the second inclined groove on the upper air deflector and the lower air deflector, the resistance of the inclined grooves to the air flow is small, in the case that the air baffles are removed, the air conditioner is controlled to run in the windless blowing mode, and the upper air deflector and the lower air deflector are controlled to close the air outlet, the air flow is blown out through the first inclined groove and the second inclined groove, the air volume is large, and the comfort of the user is improved;

[0011] 2. In the case of the installation of the wind deflector, the air conditioner is controlled to run in the cooling blowing mode, so that the air outlet direction formed by the upper and lower wind deflectors is upward, and the air conditioner is controlled to run in the heating blowing mode, so that the air outlet direction formed by the upper and lower wind deflectors is toward the wall surface, which not only ensures the cooling or heating capacity, but also avoids the direct blowing of cold or hot air to the user, thereby improving the comfort of the user.

[0012] In an optional embodiment, in the case of the closing of the upper wind deflector, the air outlet direction of the first inclined slot is parallel to the horizontal plane or is upwardly inclined relative to the horizontal plane.

[0013] In an optional embodiment, in the case of the closing of the upper wind deflector, the air outlet direction of the first inclined slot is upwardly inclined relative to the horizontal plane by an angle in the range of 0°-30°.

[0014] In this way, in the case of the closing of the upper wind deflector, the air outlet of the first inclined slot is upward, which does not directly blow to the user, thereby improving the comfort of the user.

[0015] In an optional embodiment, in the case of the closing of the lower wind deflector, the air outlet direction of the second inclined slot is parallel to the vertical plane or is wall surface-tilted relative to the vertical plane.

[0016] In an optional embodiment, in the case of the closing of the upper wind deflector, the air outlet direction of the second inclined slot is wall surface-tilted relative to the vertical plane by an angle in the range of 0°-30°.

[0017] In this way, in the case of the closing of the lower wind deflector, the air outlet of the second inclined slot is toward the wall surface, which does not directly blow to the user, thereby improving the comfort of the user.

[0018] In an optional embodiment, the upper wind deflector comprises:

[0019] two oppositely arranged first vertical edge strips;

[0020] a plurality of uniformly spaced first horizontal strips, both ends of each first horizontal strip being connected to the two first vertical edge strips, and a first inclined slot being formed between adjacent two first horizontal strips.

[0021] In an optional embodiment, the lower wind deflector comprises:

[0022] two oppositely arranged second vertical edge strips;

[0023] a plurality of uniformly spaced second horizontal strips, both ends of each second horizontal strip being connected to the two second vertical edge strips, and a second inclined slot being formed between adjacent two second horizontal strips.

[0024] In this way, the upper and lower wind deflectors have a simple structure, and more importantly, the lengths of the first and second inclined slots basically reach the length of the wind deflector, so as to maximize the air outlet amount of the inclined slots.

[0025] In an optional embodiment, the two wind baffles are respectively detachably mounted on the inner sides of the upper and lower air deflectors.

[0026] In this way, when the upper and lower air deflectors are opened, the air blown by the air conditioner directly contacts the wind baffles, is guided by the wind baffles, and does not enter the first and second inclined grooves, so as not to disturb the air outlet and improve the air outlet volume.

[0027] In an optional embodiment, the inner sides of the upper and lower air deflectors are each provided with a clamping groove, and the wind baffles are each provided with a clamping block which is detachably clamped with the clamping groove.

[0028] In this way, the wind baffles are convenient to disassemble and assemble with the upper and lower air deflectors.

[0029] In a second aspect, the application provides a control method of an air conditioner, which is applied to the air conditioner of any one of the preceding embodiments and comprises the following steps:

[0030] In the case that the wind baffles are disassembled, the air conditioner is controlled to run the windless blowing mode, and the upper and lower air deflectors are controlled to close the air outlet.

[0031] In an optional embodiment, the control method of the air conditioner further comprises the following steps:

[0032] In the case that the wind baffles are assembled, the air conditioner is controlled to run the cooling blowing mode, and the air outlet direction formed by the upper and lower air deflectors is controlled to be upwardly inclined relative to the horizontal plane by an angle range of 0°-60°.

[0033] In an optional embodiment, the step of controlling the air outlet direction formed by the upper and lower air deflectors to be upwardly inclined relative to the horizontal plane by an angle range of 0°-60° comprises the following steps:

[0034] The upper air deflector is controlled to be upwardly flipped to a limit position, and the lower air deflector is controlled to be opened by a first preset angle.

[0035] In an optional embodiment, the first preset angle ranges from 0° to 45°.

[0036] In an optional embodiment, the control method of the air conditioner further comprises the following steps:

[0037] In the case that the wind baffles are assembled, the air conditioner is controlled to run the heating blowing mode, and the air outlet direction formed by the upper and lower air deflectors is controlled to be inclined relative to the vertical plane to the wall surface by an angle range of 0°-30°.

[0038] In an optional embodiment, the step of controlling the air outlet direction formed by the upper and lower air deflectors to be inclined relative to the vertical plane to the wall surface by an angle range of 0°-30° comprises the following steps:

[0039] Control the upper air guide plate to open to the second preset angle, and the lower air guide plate to flip downward to the extreme position.

[0040] In an optional implementation, the range of the second preset angle is 0° to 60°.

[0041] The beneficial effects of the air conditioner control method provided in this embodiment include:

[0042] 1. Even with the wind deflector removed and the air outlet closed by the upper and lower air guide plates, the airflow can still be blown out through the first and second inclined slots, resulting in a large air volume without directly blowing on the user, thus improving user comfort.

[0043] 2. When the wind deflector is installed and the air conditioner is running in cooling mode, the air outlet direction formed by the upper and lower air deflectors is upward, which ensures the cooling capacity and avoids cold air blowing directly on the user, thus improving the user's comfort.

[0044] 3. When the baffle is installed and the air conditioner is running in heating mode, the air outlet direction formed by the upper and lower air guide plates can be directed towards the wall, which not only ensures the heating capacity, but also avoids hot air blowing directly on the user, thus improving the user's comfort.

[0045] 4. Removable baffles are provided on the upper and lower air guide plates to prevent airflow from leaking out of the first and second inclined slots when the air conditioner is running in cooling or heating mode, thus ensuring the cooling or heating capacity. Attached Figure Description

DETAILED DESCRIPTION

[0058] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings.

[0059] Please refer to Figures 1 to 3 , the arrow in the drawing represents the air outlet direction, the air conditioner 1 is a wall-mounted type, and the air conditioner 1 comprises a shell 2, an upper air deflector 3 and a lower air deflector 4.

[0060] Among them, the shell 2 is provided with an air outlet 21, the upper air deflector 3 is rotatably installed on the upper edge of the air outlet 21, and the upper air deflector 3 is provided with a first inclined groove 31, the first inclined groove 31 extends along the length direction of the upper air deflector 3, and the first inclined groove 31 penetrates through the thickness direction of the upper air deflector 3.

[0061] Specifically, the upper air deflector 3 comprises first vertical edge strips 32 and first horizontal strips 33, the two first vertical edge strips 32 are oppositely arranged, and the plurality of first horizontal strips 33 are uniformly arranged at intervals, the two ends of the first horizontal strip 33 are connected to the two first vertical edge strips 32 respectively, and the first inclined groove 31 is formed between the adjacent two first horizontal strips 33. In this way, the structure of the upper air deflector 3 is simple, and more importantly, the length of the first inclined groove 31 basically reaches the length of the upper air deflector 3, so as to maximize the air volume of the first inclined groove 31.

[0062] In the case that the upper air deflector 3 is closed, the air outlet direction of the first inclined groove 31 is parallel to the horizontal plane, or is upwardly inclined relative to the horizontal plane, thereby avoiding the straight blowing of the air outlet to the user and improving the comfort of the user.

[0063] Preferably, the first inclined chute 31 is inclined upward at an angle ranging from 0° to 30° with respect to the horizontal plane when the upper air deflector 3 is closed. In this way, the air outlet direction of the first inclined chute 31 is upward when the upper air deflector 3 is closed, so that the air outlet direction is not directly blowing on the user, thereby improving the comfort of the user.

[0064] The lower air deflector 4 is rotatably installed at the lower edge of the air outlet 21, and the second inclined chute 41 is formed in the lower air deflector 4 and extends along the length direction of the lower air deflector 4, and the second inclined chute 41 penetrates through the thickness direction of the lower air deflector 4.

[0065] Specifically, the lower air deflector 4 includes two second vertical edge strips 42 and a plurality of second horizontal strips 43, the two second vertical edge strips 42 are oppositely arranged, and the plurality of second horizontal strips 43 are uniformly arranged, the two ends of each second horizontal strip 43 are connected to the two second vertical edge strips 42 respectively, and the second inclined chute 41 is formed between adjacent two second horizontal strips 43. In this way, the structure of the lower air deflector 4 is simple, and more importantly, the length of the second inclined chute 41 basically reaches the length of the lower air deflector 4, so as to maximize the air outlet amount of the second inclined chute 41.

[0066] When the lower air deflector 4 is closed, the air outlet direction of the second inclined chute 41 is parallel to the vertical plane or is inclined to the wall surface with respect to the vertical plane, thereby avoiding the air outlet directly blowing on the user, and improving the comfort of the user. The wall surface mentioned here is the wall surface on which the air conditioner 1 is installed.

[0067] Preferably, the air outlet direction of the second inclined chute 41 is inclined to the wall surface at an angle ranging from 0° to 30° with respect to the vertical plane when the upper air deflector 3 is closed. In this way, the air outlet direction of the second inclined chute 41 is toward the wall surface when the lower air deflector 4 is closed, so that the air outlet direction is not directly blowing on the user, thereby improving the comfort of the user.

[0068] Please refer to Figure 4 and Figure 5 The air conditioner 1 further includes two air baffle plates 6, and the two air baffle plates 6 are respectively detachably installed on the upper air deflector 3 and the lower air deflector 4, and are used for respectively shielding the first inclined chute 31 and the second inclined chute 41. In this way, when the upper air deflector 3 and the lower air deflector 4 open the air outlet 21, the air outlet direction of the air conditioner 1 will not pass through the first inclined chute 31 and the second inclined chute 41, so that the air outlet direction is strictly according to the air outlet direction formed by the upper air deflector 3 and the lower air deflector 4, thereby ensuring the accurate control of the air outlet direction.

[0069] Preferably, the two air baffle plates 6 are respectively detachably installed on the inner sides of the upper air deflector 3 and the lower air deflector 4. In this way, when the upper air deflector 3 and the lower air deflector 4 are opened, the air blown out by the air conditioner 1 directly contacts the air baffle plates 6 and is guided by the air baffle plates 6, so that the air will not enter the first inclined chute 31 and the second inclined chute 41, thereby avoiding the air outlet being disturbed, and improving the air outlet amount.

[0070] Please refer to Figures 6 to 8 The upper air guide plate 3 and the lower air guide plate 4 both have slots 5 on their inner sides. Each end of the air guide plate (including the upper air guide plate 3 and the lower air guide plate 4) also has slots 5, with multiple slots 5 available at each end. Each baffle plate 6 has locking blocks 7, the number of which is equal to the number of slots 5. The arrangement of the locking blocks 7 is the same as that of the slots 5, and the locking blocks 7 correspond one-to-one with the slots 5 and are detachably engaged. This makes it easy to assemble and disassemble the baffle plate 6 from the upper air guide plate 3 and the lower air guide plate 4.

[0071] In other embodiments, a locking block 7 may be provided on the inner side of the upper air guide plate 3 and the lower air guide plate 4, a slot 5 may be opened on the wind baffle plate 6, or other detachable connection methods may be used, such as using a U-shaped clamp to directly clamp the wind baffle plate 6 and the air guide plate together.

[0072] This embodiment also provides a control method for the air conditioner 1 described above, the method including the following steps:

[0073] S1: Please refer to Figure 3 With the wind deflector 6 removed, control the air conditioner 1 to run in a windless blowing mode, and control the upper air guide plate 3 and the lower air guide plate 4 to close the air outlet 21.

[0074] In this way, by opening the first inclined groove 31 and the second inclined groove 41 on the upper air guide plate 3 and the lower air guide plate 4 respectively, the inclined grooves have less resistance to airflow. When the baffle plate 6 is removed, the air conditioner 1 is controlled to run in the windless blowing mode, and the upper air guide plate 3 and the lower air guide plate 4 are controlled to close the air outlet 21. The airflow is blown out through the first inclined groove 31 and the second inclined groove 41, with a large air volume and no direct blowing to the user, thus improving the user's comfort.

[0075] S2: Please refer to Figure 9 With the wind deflector 6 installed, the air conditioner 1 is controlled to operate in cooling mode, and the angle range of the air outlet direction formed by the upper air guide plate 3 and the lower air guide plate 4 relative to the horizontal plane is controlled to be 0°~60°.

[0076] Specifically, the upper air guide plate 3 is controlled to flip upward to its extreme position, and the lower air guide plate 4 is opened to a first preset angle. The range of the first preset angle is 0° to 45°.

[0077] In this way, the air outlet direction formed by the upper air guide plate 3 and the lower air guide plate 4 is upward, which not only ensures the cooling capacity, but also avoids cold air blowing directly on the user, thus improving the user's comfort.

[0078] S3: Please refer to Figure 10With the baffle plate 6 installed, the air conditioner 1 is controlled to operate in heating and blowing mode, and the angle range of the air outlet direction formed by the upper air guide plate 3 and the lower air guide plate 4 relative to the vertical surface of the wall is controlled to be 0°~30°.

[0079] Specifically, the upper air guide plate 3 is opened to a second preset angle, and the lower air guide plate 4 is flipped downwards to its extreme position. The range of the second preset angle is 0° to 60°.

[0080] In this way, the air outlet direction formed by the upper air guide plate 3 and the lower air guide plate 4 is directed towards the wall, which not only ensures the heating capacity, but also avoids hot air blowing directly on the user, thus improving the user's comfort.

[0081] The beneficial effects of the air conditioner 1 and its control method provided in this embodiment include:

[0082] 1. Even with the wind deflector 6 removed and the air outlet 21 closed by the upper air guide plate 3 and the lower air guide plate 4, the airflow can still be blown out through the first inclined groove 31 and the second inclined groove 41, resulting in a large air volume and preventing direct airflow to the user, thus improving the user's comfort.

[0083] 2. When the wind deflector 6 is installed and the air conditioner 1 is running the cooling air blowing mode, the air outlet direction formed by the upper air guide plate 3 and the lower air guide plate 4 can be directed upward, which ensures the cooling capacity and avoids cold air blowing directly on the user, thus improving the user's comfort.

[0084] 3. When the baffle plate 6 is installed and the air conditioner 1 is running the heating blowing mode, the air outlet direction formed by the upper air guide plate 3 and the lower air guide plate 4 can be directed towards the wall, which not only ensures the heating capacity, but also avoids hot air blowing directly on the user, thus improving the user's comfort.

[0085] 4. A removable baffle plate 6 is provided on the upper air guide plate 3 and the lower air guide plate 4, which can prevent airflow from leaking out from the first inclined groove 31 and the second inclined groove 41 when the air conditioner 1 is running in cooling or heating mode, thus ensuring the cooling or heating capacity.

[0086] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
