Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly, to an air conditioner and an air conditioner control method. Background Art

[0002] With the improvement of people's living standards and the emphasis on health, fresh air air conditioners have become a rapidly growing category of products in the air conditioner industry. While the fresh air function of fresh air air conditioners brings healthy air to consumers, the requirements for the appearance refinement, cost, and comfort of the products are also getting higher and higher.

[0003] Most of the existing fresh air air conditioners adopt two methods for the layout of fresh air outlets:

[0004] The first method is to independently set the fresh air outlet and the main air duct outlet. It is necessary to set related components such as baffles for opening and closing the air outlet and adjusting the wind direction and speed at both the fresh air outlet and the main air duct outlet, that is, it is necessary to set two sets of related components such as baffles for opening and closing the air outlet and adjusting the wind direction and speed; this makes the number of structural components of the product large, the movement mechanism complex, the manufacturing labor intensity high, the manufacturing efficiency low, the manufacturing cost high, and it will also affect the appearance refinement of the product.

[0005] The second method is to borrow the main air duct outlet for the fresh air outlet, that is, the fresh air blown out by the fresh air fan is then inhaled through the main fan air duct and blown out through the air outlet structure of the main fan. When the fresh air function of the product with this layout method is turned on, the main fan system must be turned on, and the air sent out is a mixture of fresh air and indoor recycled air, and the effect of fresh air cannot be directly felt. At the same time, the operation of the two fan systems affects the energy consumption and noise of the product. Summary of the Invention

[0044] Specifically, the inlet of the air inlet passage 21 is communicated with the outside of the air conditioner.

[0045] Specifically, the air conditioning air outlet portion 31 includes at least one air conditioning air outlet 311. When there are multiple air conditioning air outlets 311, the multiple air conditioning air outlets 311 are distributed at intervals.

[0046] Specifically, the fresh air outlet portion 32 includes at least one fresh air outlet 321. When there are multiple fresh air outlets 321, the multiple fresh air outlets 321 are distributed at intervals.

When there are multiple baffles 40, there are multiple preset axes, and the multiple baffles 40 are arranged one by one corresponding to the multiple preset axes; the multiple preset axes are parallel; the multiple baffles 40 are sequentially distributed along a direction perpendicular to the extension direction of the preset axes, so that the multiple baffles 40 cover the preset opening 33 together, or at least part of the multiple baffles 40 rotate.

[0048] In this embodiment, the baffle 40 has a first end and a second end that are arranged opposite to each other; the distribution direction of the first end and the second end of the baffle 40 is perpendicular to the extension direction of the preset axis, and the distribution direction of the first end and the second end of the baffle 40 is perpendicular to the plate thickness direction of the baffle 40. Along the distribution direction of the first end and the second end of the baffle 40, the preset axis is located at the first end of the baffle 40, or the preset axis is located between the first end and the second end of the baffle 40.

[0049] Optionally, when there are multiple baffles 40, the multiple preset axes are all located at the first end of the corresponding baffle 40; or, the multiple preset axes are all located between the first end and the second end of the corresponding baffle 40.

[0052] Specifically, along the strip extension direction of the baffle 40, connecting shafts are provided at both ends of the baffle 40, and the central axes of the two connecting shafts both coincide with the preset axis; two connecting holes are provided on the housing 30, and the two connecting shafts are rotatably arranged in the two connecting holes in a one-to-one correspondence.

[0053] The present invention also provides an air conditioner control method, which is applicable to the above-mentioned air conditioner. The air conditioner has three operating modes, which are a conventional mode without the fresh air function, a fresh air mode with the independent operation of the fresh air function, and a linkage mode of the conventional and fresh air. That is, when the air conditioner operates in the conventional mode, only the air outlet part 31 of the air conditioner blows air; when the air conditioner operates in the fresh air mode, only the fresh air outlet part 32 blows air; when the air conditioner operates in the linkage mode, both the air outlet part 31 of the air conditioner and the fresh air outlet part 32 blow air.

[0054] Regardless of whether the air conditioner operates in the conventional mode, or the fresh air mode, or the linkage mode, the baffle 40 is used to achieve rectifying air sweeping, expanding the air supply range or achieving directional air supply.

[0055] For the case where the air conditioner includes only one baffle 40, when the baffle 40 of the air conditioner is in the initial position, this one baffle 40 blocks the preset opening 33, so that the preset opening 33 of the air conditioner is in the closed state. For the case where the air conditioner includes multiple baffles 40, when the multiple baffles 40 of the air conditioner are all in the initial position, the multiple baffles 40 jointly block the preset opening 33, so that the preset opening 33 of the air conditioner is in the closed state.

[0057] When the air conditioner operates in the conventional mode, the air-conditioning control method includes: Step S11: Rotate the baffle 40 from the initial position by a first angle to open the preset opening 33; wherein, for the case where the air conditioner includes a plurality of baffles 40, this means that each baffle 40 rotates from its respective initial position by the first angle to open the preset opening 33. Step S12: Turn on the main fan 11 and increase the speed of the main fan 11 to Q1 for operation; do not start the fresh air fan 22 and do not operate the shielding portion 25.

[0058] Specifically, in step S12, the shielding portion 25 is kept at its initial position.

[0059] When the air conditioner operates in the fresh air mode, the air-conditioning control method includes: Step S21: Rotate the baffle 40 and the shielding portion 25 simultaneously, so that the baffle 40 rotates from the initial position by a first angle to open the preset opening 33; and rotate the shielding portion 25 from the initial position by a second angle to put the air inlet channel 21 in a communicating state; wherein, for the case where the air conditioner includes a plurality of baffles 40, this means that the plurality of baffles 40 and the shielding portion 25 rotate simultaneously, so that the plurality of baffles 40 all rotate from their respective initial positions by the first angle to open the preset opening 33. Step S22: Turn on the fresh air fan 22 and increase the speed of the fresh air fan 22 to Q2 for operation; do not start the main fan 11.

[0060] When the air conditioner operates in the linkage mode, the air-conditioning control method includes: Step S31: Rotate the baffle 40 and the shielding portion 25 simultaneously from their respective initial positions; wherein, for the case where the air conditioner includes a plurality of baffles 40, this means that the plurality of baffles 40 and the shielding portion 25 rotate simultaneously from their respective initial positions. Step S32: When the baffle 40 rotates from the initial position by a first angle to open the preset opening 33, turn on the main fan 11 and increase the speed of the main fan 11 to Q3 for operation; when the baffle 40 rotates from the initial position by a first angle to open the preset opening 33, and when the shielding portion 25 rotates from the initial position by a second angle to put the air inlet channel 21 in a communicating state, turn on the fresh air fan 22 and increase the speed of the fresh air fan 22 to Q4 for operation; wherein, make Q3 less than Q1, and / or, make Q4 less than Q2.

[0061] For the case where the air conditioner includes a plurality of baffles 40, in step S32, it means that when the plurality of baffles 40 rotate from their respective initial positions by a first angle to open the preset opening 33, turn on the main fan 11 and increase the speed of the main air duct motor 12 to Q3 for operation; when the plurality of baffles 40 rotate from their respective initial positions by a first angle to open the preset opening 33, and when the shielding portion 25 rotates from the initial position by a second angle to put the air inlet channel 21 in a communicating state, turn on the fresh air fan 22 and increase the speed of the fresh air fan 22 to Q4 for operation.

[0062] The value range of the first angle is greater than or equal to a first preset value, and the value range of the second angle is greater than or equal to a second preset value.

[0063] In this embodiment, the air conditioner control method further includes: controlling the rotation speed of the main air duct motor 12 to control the rotation speed of the main blower 11; controlling the rotation speed of the fresh air motor 24 to control the rotation speed of the fresh air blower 22.

[0064] Specifically, by turning on the main air duct motor 12, the main blower 11 is turned on; by raising the rotation speed of the main air duct motor 12 to R1 for operation, the rotation speed of the main blower 11 is raised to Q1 for operation; by raising the rotation speed of the main air duct motor 12 to R3 for operation, the rotation speed of the main blower 11 is raised to Q3 for operation; by making R3 less than R1, Q3 is made less than Q1.

[0065] Specifically, by turning on the fresh air motor 24, the fresh air blower 22 is turned on; by raising the rotation speed of the fresh air motor 24 to R2 for operation, the rotation speed of the fresh air blower 22 is raised to Q2 for operation; by raising the rotation speed of the fresh air motor 24 to R4 for operation, the rotation speed of the fresh air blower 22 is raised to Q4 for operation; by making R4 less than R2, Q4 is made less than Q2.

[0066] Specifically, in step S12: turn on the main air duct motor 12 and raise the rotation speed of the main air duct motor 12 to R1 for operation; do not start the fresh air motor 24.

[0067] Specifically, in step S21, turn on the fresh air motor 24 and raise the rotation speed of the fresh air motor 24 to R2 for operation; do not start the main air duct motor 12.

[0068] Optionally, the value range of R1 is 600 r / min to 1200 r / min; the value range of R2 is 500 r / min to 2000 r / min. Wherein, r / min is revolutions per minute.

[0069] Specifically, R1 - R3 = ΔR1; R2 - R4 = ΔR2. Optionally, the value range of ΔR1 is 0 to 1200 r / min; the value range of ΔR2 is 0 to 2000 r / min.

[0070] Specifically, the value range of the first preset value is 30 degrees to 50 degrees; the value range of the second preset value is 20 degrees to 40 degrees.

[0071] According to the above air conditioner control method, regardless of whether the air conditioner operates in the conventional mode, fresh air mode, or linkage mode, when the air conditioner is turned on, the baffle 40 will first act to open the preset opening 33. The purpose of this setting is to make the fresh air motor 24 and / or the main air duct motor 12 turn on later than the baffle 40, so as to effectively avoid the problem that when the motor starts, there is wind, but the baffle 40 blocks the preset opening 33, resulting in the wind not being able to blow out, thereby generating noise or causing problems with the reliability of use.

[0072] In addition, by adopting the air conditioner control method of the present application: 1. It can effectively avoid the problem that the fresh air motor 24 and / or the main air duct motor 12 start when the shielding part 25 and / or the baffle 40 are not opened, resulting in large fluctuations in the motor load and affecting the service life of the motor; 2.

[0075] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0076] In the air conditioner provided by the present invention, the air conditioner includes a housing 30, a main air component 10, a fresh air component 20, and a baffle 40. The housing 30 has an air conditioner air outlet part 31, a fresh air outlet part 32, and a preset opening 33. The air conditioner air outlet part 31 and the fresh air outlet part 32 are independently arranged. Both the air conditioner air outlet part 31 and the fresh air outlet part 32 are located inside the preset opening 33, and both the air conditioner air outlet part 31 and the fresh air outlet part 32 communicate with the preset opening 33, so that the air conditioner air blown out by the air conditioner air outlet part 31 and the fresh air blown out by the fresh air outlet part 32 both pass through the preset opening 33 and are blown to the outside of the air conditioner. The air conditioner air outlet part 31 and the fresh air outlet part 32 are distributed along a first direction. The baffle 40 is movably arranged at the preset opening 33 to open or close the preset opening 33. The main air component 10 includes a main air blower 11. The main air blower 11 is oppositely arranged with the air conditioner air outlet part 31 and is rotatably arranged, so that under the action of the main air blower 11, the air conditioner air outlet part 31 blows out air conditioner air. The fresh air component 20 includes a fresh air blower 22, an air inlet channel 21, and a shielding part 25. The outlet of the air inlet channel 21 is communicated with the inlet of the fresh air blower 22. At least part of the fresh air component 20 is oppositely arranged with the fresh air outlet part 32, so that under the action of the fresh air component 20, the fresh air outlet part 32 blows out fresh air. The shielding part 25 is rotatably arranged in the air inlet channel 21, so that the shielding part 25 stops in the air inlet channel 21, or the end of the shielding part 25 is spaced from the inner wall of the air inlet channel 21, and further the shielding part 25 is in a blocking state or a yielding state, so that the air inlet channel 21 is in a disconnected state or a connected state.

[0077] In the air conditioner of the present application, the air conditioner air outlet part 31 and the fresh air outlet part 32 are independently arranged and share the baffle 40, that is, only by the baffle 40 can the air outlet of both the air conditioner air outlet part 31 and the fresh air outlet part 32 be controlled at the same time, which simplifies the overall structure of the air conditioner, is beneficial to controlling the cost of the air conditioner and improving the manufacturing efficiency of the air conditioner, and solves the problem that the overall structure of the air conditioner in the prior art is complicated when the fresh air outlet and the main air duct outlet are independently arranged.
