Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a control method and device for an air conditioner and an air conditioner. Background Art

[0002] With the improvement of living standards and technological advancement, people's demand for air conditioning is not just simple cooling and heating, but they have higher requirements for air conditioning comfort.

[0003] Specifically, an air guide plate is provided at the air outlet of the air conditioner. The rotation angle of the air guide plate is adjusted to change the outlet direction of the airflow guided from the air outlet to the indoor environment. However, most of the wall-mounted air conditioners on the market nowadays are only equipped with a single air duct, resulting in that the air conditioner can only use the same air duct when operating the cooling or heating function. Combined with the actual situation that hot air flows upward and cold air flows downward, the air guide plate cannot effectively adjust the outlet direction of the hot air flow and the cold air flow, thereby reducing the user experience. Summary of the invention

[0004] The technical problem solved by the present invention is that most of the wall-mounted air conditioners on the market today are limited to the situation that only a single air duct is provided, resulting in that the air conditioner can only use the same air duct when operating the cooling or heating function, making it impossible for the air guide plate to effectively adjust the air outlet direction of the hot air flow and the cold air flow, thereby reducing the user experience.

[0005] To solve the above problems, the present invention provides an air conditioner, comprising: a shell, a plurality of air ducts are arranged in the shell, and an air outlet is arranged at the bottom of the shell; an air guide plate, the air guide plate is rotatably connected to the air outlet, and can be switched between a first state and a second state relative to the air outlet to change the air outlet direction of the air flow guided out by the air outlet; when the air guide plate is in the first state, the air outlet is connected to the plurality of air ducts at the same time, and when the air guide plate is in the second state, it is used to prevent the air outlet from being connected to any one of the plurality of air ducts.

[0006] Compared with the prior art, the technical effect achieved by adopting the technical solution is as follows: in combination with the characteristic that the air conditioner has multiple air ducts, the air guide plate can be adjusted to open the air duct with the air duct opening facing vertically downward or obliquely downward, so as to facilitate the introduction of the hot air flow into the lower position of the indoor environment at the first time, effectively preventing the feeling of hot head and cold feet, thereby effectively improving the user experience; in addition, when the air conditioner is running the cooling function, for example, when the operation stage is the startup stage, in order to achieve rapid cooling of the indoor environment in a short time, the air guide plate can be kept in the first state to open all the air ducts; and when the air conditioner enters the steady-state stage, that is, when the indoor temperature of the indoor environment is close to the set temperature of the air conditioner, the air guide plate can be adjusted to remain in the second state to close at least one of the multiple air ducts. On the one hand, by reducing the air outlet, the indoor temperature is prevented from being too low; on the other hand, the air guide plate can be closed with the air duct arranged in the horizontal direction or obliquely in front, thereby effectively reducing the air outlet distance of the air conditioner to the user side, effectively avoiding the situation of direct blowing of cold air, and further improving the user experience. Therefore, in combination with the above content, the present technical solution can flexibly adjust the coordination relationship between the air guide plate and the multiple air ducts according to the actual operating function of the air conditioner, thereby improving the heat exchange efficiency between the air conditioner and the indoor environment to meet the actual needs of the user, and effectively avoiding the situation in which the air conditioner is operating the cooling or heating function, while still using the same single air duct without fully combining the diffusion direction of the hot air flow and the cold air flow, thereby reducing the use efficiency of the air conditioner.

[0007] In one example of the present invention, when the air guide plate is in the first state, the air outlet is divided into a first air outlet and a second air outlet; the first air outlet is connected to any one of the multiple air ducts, and the second air outlet is connected to any one of the remaining multiple air ducts.

[0008] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: Specifically, the separation effect of the air guide plate is used to effectively prevent the airflows in multiple air ducts leading to the indoor environment from affecting each other, such as reducing the air outlet distance, thereby reducing the heat interaction efficiency between the air conditioner and the indoor environment. It can be understood that the air duct outlets of multiple air ducts are arranged at an angle to achieve air supply in different directions to the indoor environment, and the blocking effect of the air guide plate prevents the air outlet direction of one of the air ducts from being different from that of the others, thereby preventing the two from interacting with each other, such as mixing with each other, thereby reducing the air supply distance, resulting in a reduction in the heat exchange efficiency between the air conditioner and a distant location.

[0009] In an example of the present invention, when the air guide plate rotates relative to the shell while maintaining the first state, the size of the air outlet diameter of the first air outlet and / or the second air outlet is changed.

[0010] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: while keeping multiple air ducts in an open state, the air volume and air outlet direction of the corresponding air ducts are adjusted by rotating the air guide plate, so as to achieve refined control of the air volume and air outlet direction, thereby improving the user experience.

[0011] In an example of the present invention, when the air guide plate is in the second state, the air outlet direction is vertically downward or horizontally.

[0012] Compared with the prior art, the technical effect achieved by adopting this technical solution is: for example, when the air conditioner is combined with the heating function, the air outlet direction can be set vertically downward, thereby effectively ensuring the heat exchange of the air conditioner to the area below it, thereby effectively avoiding the hot air flow from being unable to interact with the heat in this area and diffusing to the upper area of ​​the air conditioner.

[0013] In one embodiment of the present invention, multiple fans are provided in the multiple air ducts, and the multiple fans are matched with the multiple air ducts one by one; or, a single fan is provided in the shell, and the fan is provided at one end of the multiple air ducts away from the air outlet.

[0014] Compared with the prior art, the technical effect achieved by adopting this technical solution is: for example, the number of fans can be multiple, so that the air volume can be increased through the coordinated operation of multiple fans, thereby improving the heat exchange efficiency between the air conditioner and the indoor environment.

[0015] In one embodiment of the present invention, the number of multiple air ducts is two, one of which is defined as the first air duct and the other as the second air duct; a partition for forming the first air duct and the second air duct is provided in the shell; an air guide plate is located between the first air duct and the second air duct, and the air guide plate is driven by a driving component of the air conditioner to switch between the first state and the second state; wherein, when the shell is installed to the indoor environment through a hanging plate, the air duct outlet of the one of the first air duct and the second air duct that is located in a higher vertical position faces vertically downward.

[0016] Compared with the prior art, the technical effect achieved by adopting this technical solution is: the heat exchange efficiency between the air conditioner and the indoor environment is further improved.

[0017] On the other hand, the present invention also provides a control method for an air conditioner, which is applied to an air conditioner as in any of the above examples; the control method includes: after the air conditioner is turned on, determining whether the air conditioner receives a heating operation function instruction; if so, controlling the air guide plate to open an air duct having a vertical downward air duct opening; and controlling the operation of the fan in the air duct that is in the open state.

[0018] Compared with the prior art, the technical effect achieved by adopting this technical solution is that it can realize the technical effect corresponding to any technical solution in the above-mentioned air conditioner example, which will not be repeated here.

[0019] In one example of the present invention, an air duct having an air duct opening facing vertically downward is defined as a first air duct, and the fan inside the air duct is the first fan; the remaining air ducts among the multiple air ducts are second air ducts, and the fans inside the air ducts are the second fans; the air guide plate is controlled to open the air duct having the air duct opening facing vertically downward, including: when T1>Tn, the air guide plate is controlled to be in a first state, and the first fan and the second fan are controlled to operate; when T2>Tn≥T1, the air guide plate is controlled to be in a second state to close the second air duct, and open the first air duct and start the first fan; when Tn≥T2, the air guide plate is controlled to be in the second state to close the second air duct, and open the first air duct and start the first fan, and turn off the outdoor compressor of the air conditioner; wherein Tn is the indoor temperature value, and T1 and T2 are preset values ​​respectively.

[0020] Compared with the prior art, the technical effect achieved by adopting this technical solution is: the heat exchange efficiency between the air conditioner and the indoor environment is further improved.

[0021] In one example of the present invention, an air duct having a vertical downward air duct opening is defined as a first air duct, and the fan inside the air duct is a first fan; the remaining air ducts among the multiple air ducts are second air ducts, and the fans inside the air ducts are second fans; judging whether the air conditioner receives a heating operation function instruction includes: if not, judging whether the air conditioner runs a cooling function; if so, when Tn>T3, controlling the air guide plate to be in a first state, and controlling the first fan and the second fan to run simultaneously; when T3≥Tn>T4, controlling the air guide plate to be in a second state to close the first air duct and the first fan, and to open the second air duct and to start the second fan; when T4≥Tn, controlling the air guide plate to be in a second state to close the first air duct and the first fan, and to open the second air duct and to start the second fan, and to turn off the outdoor compressor of the air conditioner; wherein Tn is the indoor temperature value, and T3 and T4 are preset values ​​respectively.

[0022] Compared with the prior art, the technical effect achieved by adopting this technical solution is: the heat exchange efficiency between the air conditioner and the indoor environment is further improved.

[0023] On the other hand, the present invention also provides a control device for an air conditioner, which is applied to an air conditioner as in any of the above examples; the control device includes: a judgment module, the judgment module is used to judge whether the air conditioner receives a heating operation function instruction; a control module, the control module is used to control the air guide plate to open the air duct with a vertical downward air duct opening when determining that the air conditioner receives the heating operation function instruction, and control the operation of the fan in the air duct in the open state.

[0024] Compared with the prior art, the technical effect achieved by adopting this technical solution is that it can realize the technical effect corresponding to any technical solution in the above-mentioned air conditioner example, which will not be repeated here.

[0025] After adopting the technical solution of the present invention, the following technical effects can be achieved:

[0026] (1) The coordination relationship between the air guide plate and the multiple air ducts is flexibly adjusted according to the actual operating function of the air conditioner, thereby improving the heat exchange efficiency between the air conditioner and the indoor environment to meet the actual needs of the user, and effectively avoiding the situation in which the air conditioner still uses the same single air duct during the cooling or heating operation without fully combining the characteristics of the diffusion direction of the hot air flow and the cold air flow, thereby reducing the efficiency of the air conditioner;

[0027] (2) The air guide plate's separating function effectively prevents the airflows in multiple air ducts from affecting each other, such as reducing the air outlet distance, thereby reducing the heat exchange efficiency between the air conditioner and the indoor environment. It is understandable that the air outlets of multiple air ducts are arranged at an angle to achieve air supply to the indoor environment in different directions, and the air guide plate's blocking function prevents the air outlet direction of one air duct from being different from the others, thereby preventing the two from interacting, such as mixing, with each other, thereby reducing the air supply distance, resulting in a reduction in the heat exchange efficiency between the air conditioner and a distant location.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] An air duct is arranged inside the conventional air conditioner 100, and an air outlet 11 connected to the air duct is provided. The airflow introduced into the air conditioner 100 from the air inlet 61 is compressed by the operation of the fan 40 inside the air conditioner 100, and then introduced into the indoor environment through the air outlet 11 through the air duct. Combined with the heating function of the air conditioner 100, heat exchange between the air conditioner 100 and the indoor environment is realized.

[0038] Specifically, in order to improve the heat exchange efficiency between the air conditioner 100 and different areas of the indoor environment, an air guide plate 20 is often set at the position of the air outlet 11, and the air guide plate 20 is adjusted to rotate to achieve the change of the outlet direction of the airflow introduced into the indoor environment from the air outlet 11. However, combined with the specific setting of the air guide plate 20 at the air outlet 11, for ease of understanding, when the air conditioner 100 is hung on the wall, the side facing the user is defined as the user side 101, that is, the position of the front panel, and the side that cooperates with the hanging plate is defined as the wall hanging side 102. Therefore, the air guide plate 20 is set at the bottom of the air conditioner 100 and is located between the wall hanging side 102 and the user side 101. The side of the air guide plate 20 close to the wall hanging side 102 is defined as the connecting part, and the side away from the wall hanging side 102 is defined as the matching part. The air guide plate 20 is rotated with the air conditioner 100 through the connecting part to be connected to the air conditioner 100, and as the air guide plate 20 rotates, the matching part opens or closes the air outlet 11.

[0039] Furthermore, since the traditional air conditioner 100 is only provided with a single air duct, the air conditioner 100 can only use the same air duct when operating the cooling or heating function. Combined with the actual situation that the hot air flow rises and the cold air flow falls, the air guide plate 20 cannot effectively adjust the air outlet direction of the hot air flow and the cold air flow, thereby reducing the user experience.

[0040] For example, in winter, when the air conditioner is heating, the density of the hot air blown out through the air outlet 11 is lower than the density of the indoor air, so the hot air is mostly concentrated in the upper part of the room, which easily makes people feel hot head and cold feet, affecting people's comfort experience. Although some ventilation equipment is provided with multiple air guide plates 20 at the air outlet, each air guide plate 20 needs to be independently controlled to move, which makes the air guide plate 20 device structure complex, the control process cumbersome, occupies a large space and the movement is unstable.

[0041] Therefore, in combination with this technical solution, see Figure 1 , which is a structural diagram of an air conditioner 100 provided in an embodiment of the present invention, combined with Figure 2-Figure 3The air conditioner 100, for example, includes a shell 10 and an air guide plate 20; a plurality of air ducts are provided in the shell 10, and an air outlet 11 is provided at the bottom of the shell 10; the air guide plate 20 is rotatably connected to the air outlet 11, and can be switched between a first state and a second state relative to the air outlet 11 to change the air outlet direction of the airflow guided by the air outlet 11; when the air guide plate 20 is in the first state, the air outlet 11 is connected to the plurality of air ducts at the same time, and when the air guide plate 20 is in the second state, it is used to stop the air outlet 11 from being connected to any one of the plurality of air ducts.

[0042] Specifically, since the connection or closure between the multiple air ducts and the air outlet 11 is realized by a single air guide plate 20, the overall structure of the air conditioner 100 is simplified. In addition, the connection or closure between the multiple air ducts and the air outlet 11 can be adjusted by the air guide plate 20 according to the actual operation function of the air conditioner 100.

[0043] Furthermore, in the process of adjusting the air guide plate 20 to open or close the multiple air ducts and the air outlet 11, the air outlet direction is changed, that is, the air outlet direction is different when the air guide plate 20 is maintained in the first state or the second state. Combined with the situation that the hot air flow rises when the air conditioner 100 runs the heating function, the air guide plate 20 can be adjusted to the first state or the second state according to the actual heating demand.

[0044] Based on the above content, in a specific example, in order to prevent or reduce the hot air flow from diffusing upward within the first time when it is guided out from the air outlet 11 and failing to heat the area of ​​the indoor environment located below the air conditioner 100, combined with the characteristic of the air conditioner 100 having multiple air ducts, the air guide plate 20 can be adjusted to open an air duct with an air duct opening facing vertically downward or obliquely downward, thereby facilitating the introduction of the hot air flow into the lower position of the indoor environment at the first time, effectively preventing the feeling of hot heads and cold feet, thereby effectively improving the user experience.

[0045] Furthermore, if the indoor temperature of the indoor environment is too low, in order to further improve the heat exchange efficiency between the air conditioner 100 and the indoor environment, the air guide plate 20 can also be maintained in the first state to open all the multiple air ducts, thereby increasing the air output to improve the heat exchange efficiency, and being able to discharge air at multiple angles at the same time, so that heat exchange can be performed on different areas of the indoor environment.

[0046] In contrast, if the indoor temperature of the indoor environment is high, the air guide plate 20 can be maintained in the second state, that is, at least one of the multiple air ducts is closed to reduce the air output of the air conditioner 100 and avoid the indoor environment maintaining a high temperature and affecting the user experience.

[0047] Of course, in another specific example, when the air conditioner 100 operates the cooling function, the air guide plate 20 is adjusted to switch between the first state and the second state according to the operation stage of the air conditioner 100. For example, when the operation stage is the startup stage, in order to achieve rapid cooling of the indoor environment in a short time, the air guide plate 20 can be kept in the first state to open all the air ducts; and when the air conditioner 100 enters the steady state stage, that is, when the indoor temperature of the indoor environment is close to the set temperature of the air conditioner 100, the air guide plate 20 can be adjusted to remain in the second state to close at least one of the multiple air ducts. On the one hand, by reducing the air volume, the indoor temperature is prevented from being too low; on the other hand, specifically, the air guide plate 20 can be made to close the air duct with a horizontal direction or an oblique front setting, thereby effectively reducing the air outlet distance of the air conditioner 100 to the user side 101 thereof, effectively avoiding the situation of direct blowing of cold air, and further improving the user experience.

[0048] Therefore, in combination with the above content, the present technical solution can adjust the coordination relationship between the air guide plate 20 and multiple air ducts according to the actual operating function of the air conditioner 100, thereby improving the heat exchange efficiency between the air conditioner 100 and the indoor environment to meet the actual needs of users, and effectively avoids the situation in which the air conditioner 100 is running a cooling or heating function, and still uses the same single air duct without fully combining the diffusion direction of the hot air flow and the cold air flow, thereby reducing the utilization efficiency of the air conditioner 100.

[0049] Preferably, when the air guide plate 20 is in the first state, the air outlet 11 is divided into a first air outlet 112 and a second air outlet 114; the first air outlet 112 is connected to any one of the multiple air ducts, and the second air outlet 114 is connected to any remaining one of the multiple air ducts.

[0050] Specifically, the airflows in the multiple air ducts leading to the indoor environment are effectively prevented from influencing each other by the separation effect of the air guide plate 20, such as reducing the air outlet distance, thereby reducing the heat exchange efficiency between the air conditioner 100 and the indoor environment. It is understandable that the air duct outlets of the multiple air ducts are arranged at an angle to achieve air supply in different directions to the indoor environment, and the air guide plate 20 is used to block the air flow, thereby preventing the air outlet direction of one of the air ducts from being different from the others, thereby preventing the two from interacting, such as mixing with each other, thereby reducing the air supply distance, resulting in a reduction in the heat exchange efficiency between the air conditioner 100 and a distant location.

[0051] Preferably, when the air guide plate 20 rotates relative to the housing 10 while maintaining the first state, the diameter of the air outlet 11 of the first air outlet 112 and / or the second air outlet 114 is changed. The linkage between the air guide plate 20 and the first air outlet 112 and the second air outlet 114 is improved. Specifically, when multiple air ducts are kept in an open state, the air volume and air outlet direction of the corresponding air ducts are adjusted by rotating the air guide plate 20, so as to achieve refined control of the air volume and air outlet direction, thereby improving the user experience.

[0052] Preferably, when the air guide plate 20 is in the second state, the air outlet direction is vertically downward or horizontally. For example, when the air conditioner 100 is operating the heating function, the air outlet direction can be set vertically downward, thereby effectively ensuring the heat exchange of the air conditioner 100 to the area below it, thereby effectively preventing the hot air flow from being unable to thermally interact with the area and diffusing to the area above the air conditioner 100.

[0053] Preferably, multiple fans 40 are provided in the multiple air ducts, and the multiple fans 40 cooperate with the multiple air ducts one by one; or, a single fan 40 is provided in the shell 10, and the fan 40 is arranged at one end of the multiple air ducts away from the air outlet 11.

[0054] Preferably, the number of the plurality of air ducts is two, one of which is defined as the first air duct 111 and the other as the second air duct 113; a partition 30 for forming the first air duct 111 and the second air duct 113 is provided in the housing 10; the air guide plate 20 is located between the first air duct 111 and the second air duct 113, and the air guide plate 20 is driven by the driving component of the air conditioner 100 to switch between the first state and the second state; wherein, when the housing 10 is installed to the indoor environment through the hanging plate, the air duct outlet of the one of the first air duct 111 and the second air duct 113 that is located at a higher vertical position is vertically downward. The heat exchange efficiency between the air conditioner 100 and the indoor environment is further improved.

[0055] In a specific example, an evaporator 50 is provided in the shell 10, and the evaporator 50 is located on the side of the fan 40 away from the air outlet 11, and the portion of the shell 10 corresponding to the wall-hanging side 102 is an arc-shaped surface, and an air inlet grille 60 with multiple air inlets 61 is formed on the arc-shaped surface, and a filter cover is provided at the position corresponding to the air inlet grille 60, so that dust can be effectively blocked by the filter cover.

[0057] Step S1, after the air conditioner 100 is turned on, determining whether the air conditioner 100 receives a heating operation function instruction;

[0058] Step S2: If yes, control the air guide plate 20 to open the air duct with the air duct opening facing vertically downward;

[0059] Step S3, controlling the fan 40 in the air duct in the open state to operate. This embodiment can achieve the corresponding technical effects in any of the above technical solutions, which will not be described in detail here.

[0061] Preferably, judging whether the air conditioner 100 receives the heating operation function instruction includes: if not, judging whether the air conditioner 100 runs the cooling function; if so, when Tn>T3, controlling the air guide plate 20 to be in the first state, controlling the first fan and the second fan to run simultaneously; when T3≥Tn>T4, controlling the air guide plate 20 to be in the second state to close the first air duct 111 and the first fan, and opening the second air duct 113 and turning on the second fan; when T4≥Tn, controlling the air guide plate 20 to be in the second state to close the first air duct 113 and the first fan, and opening the second air duct 113 and turning on the second fan, and turning off the outdoor compressor of the air conditioner 100; wherein Tn is the indoor temperature value, and T3 and T4 are preset values ​​respectively.
