Description

[Technical Field]

[0001] This invention claims priority from Chinese patent invention No. 202122088990.7, titled "Indoor unit and air conditioner," filed with the State Intellectual Property Office of the People's Republic of China on August 31, 2021, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to the technical field of air conditioning, and more particularly to an air conditioner. [Background technology]

[0003] In currently available air conditioner indoor units, after a user issues a command to adjust the angle of the air guide plate via a remote control, the air guide plate is installed inside the air outlet, making it difficult to observe the rotation process. Therefore, the user must wait a certain amount of time and then determine whether the angle of the air guide plate has been adjusted to the desired angle based on the feeling of the air blowing on their skin, which is extremely inconvenient.

[0004] Furthermore, since the air guide plate is built-in, its size is limited by the size of the air outlet, which reduces the air guide effect and affects the user experience. Summary of the Invention [Means for solving the problem]

[0005] To solve the problem that the rotation process of the air guide plate is not visible and the air guide effect is low in the conventional air conditioner, the present invention provides an air conditioner and uses the following technical solutions:

[0006] An air conditioner comprising a housing and an external air guide plate, an air outlet opened in the housing, the external air guide plate rotatably installed at a position on an outer wall of the housing corresponding to the air outlet to guide air blown through the air outlet, a rotary shaft installed on one side of the external air guide plate, the rotary shaft installed outside the air outlet and positioned above the air outlet, and the external air guide plate rotatably installed on the outer wall of the housing via the rotary shaft.

[0007] By using the above technical solution, users can observe the rotation angle of the outer air guide plate and then adjust the air flow according to their needs. Furthermore, since the rotation axis of the outer air guide plate is external, the air flow guidance effect is stronger and the user experience is improved.

[0008] As an option, a rotating part is provided on the outer wall of the housing at a position corresponding to the upper part of the air outlet, and the rotating shaft is rotationally engaged with the rotating part.

[0009] By using the above technical solution, the rotation of the outer air guide plate is completed by installing the rotation shaft and the rotation part, allowing the outer air guide plate to rotate by a larger angle, making it easy to control the outer air guide plate, and visualizing the rotation process and rotation angle.

[0010] Alternatively, the length of the outer air guide plate is greater than the length of the air outlet, and / or the width of the outer air guide plate is greater than the width of the air outlet.

[0011] By using the above technical solution, it is easy to guide the airflow by the outer air guide plate, and when the air conditioner is not in use, the outer air guide plate can cover the air outlet, thereby reducing the situation where dust gets into the air outlet when the outer air guide plate approaches the air outlet when rotating.

[0012] As an option, the device may further include an air guide mechanism, which is installed on the housing and, together with the outer air guide plate, is surrounded by an air guide passage that changes the air blowing direction, thereby guiding the air blown through the air outlet.

[0013] By using the above technical solution, the air guide by the outer air guide plate has directionality, and the air guide mechanism and the outer air guide plate work together to guide the air and change the air direction, which further satisfies the needs of users and improves the usage effect.

[0014] As an option, the air guide mechanism includes an inner air guide plate, which is rotatably mounted on the housing, and the outer air guide plate and the inner air guide plate are both surrounded by an air guide passage to guide the air at the air outlet.

[0015] By using the above technical solution, the inner air guide plate cooperates with the outer air guide plate to most easily realize the guidance of the airflow, and the airflow direction can be changed according to the user's needs.

[0016] As an option, the inner air guide plate is rotatably installed on a side wall of the inside of the air outlet that is separated from the outer air guide plate.

[0017] By using the above technical solution, the outer air guide plate and the inner air guide plate are installed on both sides of the air outlet, and the air blown from the air outlet is guided by the outer air guide plate and the inner air guide plate, thereby achieving a higher air guide effect.

[0018] As an option, a rotatable crank arm is provided on one side of the inner air guide plate, and an end of the rotatable crank arm away from the inner air guide plate is rotatably connected to a side wall inside the air outlet away from the outer air guide plate, and the rotatable crank arm drives the inner air guide plate to rotate in and out of the air outlet.

[0019] By using the above technical solution, the rotation angle of the inner air guide plate can be made larger by installing a rotatable crank arm, and the inner air guide plate can be easily controlled, which makes it easier to guide the airflow by the inner air guide plate.

[0020] As an option, the maximum shielding area of ​​the outer air guide plate is greater than the maximum shielding area of ​​the inner air guide plate.

[0021] By using the above technical solution, the shielding areas of the inner and outer air guide plates are different, so that the inner and outer air guide plates are less likely to interfere with each other during operation.

[0022] As an option, when the air conditioner is in an off state, the inner air guide plate is accommodated in the air outlet, and the outer air guide plate covers the air outlet.

[0023] By using the above technical solution, the outer air guide plate and the inner air guide plate are less likely to interfere with each other during operation, and the outer air guide plate blocks the air outlet in the off state, which reduces the situation where dust enters the air outlet and provides a certain protection for the inner air guide plate.

[0024] As an option, when the air conditioner switches from an off state to a heating mode, the inner air guide plate rotates to the outside of the air outlet, and the outer air guide plate rotates by a first angle, thereby guiding the airflow blown out from the air outlet to flow diagonally downward.

[0025] By using the above technical solution, since the hot air rises, the outer air guide plate and the inner air guide plate are adjusted during heating to make the air flow diagonally downward, thereby reducing the pressure on the hot air and improving the heating effect, and the inner air guide plate is rotated to the outside of the air outlet to avoid blocking the air outlet and hindering the reduction of the hot air pressure.

[0026] As an option, when the air conditioner is switched from an off state to a cooling mode, the inner air guide plate rotates to the outside of the air outlet, and the outer air guide plate rotates by a second angle, the second angle being greater than the first angle.

[0027] By using the above technical solution, cold air is different from hot air, and when it needs to be transported farther during cooling, the angle of the cold air cannot be made obliquely downward. Therefore, in this case, when installing the outer air guide plate and the inner air guide plate, the second angle is larger than the first angle, making it difficult for the cold air to flow obliquely downward and allowing it to be adjusted to a more obliquely upward angle, which is more conducive to long-distance transport of the cold air. In addition, since the outer air guide plate is installed outside the air outlet, it can be adjusted to a larger size, which improves the concentration effect of the cold air and further extends the blowing distance of the cold air, preventing the cold air from quickly falling and accumulating below the air conditioner, thereby improving the cooling effect.

[0028] Alternatively, the outer air guide plate and the inner air guide plate are both arranged in an arc shape, and when operating in the operating mode, the concave arc surface of the outer air guide plate faces the concave arc surface of the inner air guide plate.

[0029] By using the above technical solution, when the air conditioner is operating, the concave arc surfaces of the outer air guide plate and the inner air guide plate face each other, ensuring that the air is blown intensively at the air outlet, improving the air blowing process and further improving the air guidance effect.

[0030] In summary, the present invention includes at least one of the following beneficial technical effects: First, because the outer air guide plate of the air conditioner is rotatably installed on the outer wall of the housing, the rotation process and rotation angle can be observed, allowing the user to quickly determine whether the air guide angle of the outer air guide plate is adjusted to a desired angle. Furthermore, because the outer air guide plate is installed outside the air outlet, its size is not limited by the size of the air outlet and can be adjusted to a larger size, thereby achieving a better air guide effect. Therefore, the air conditioner has the characteristics of a higher air guide effect and a better user experience. Secondly, by installing the inner air guide plate, the entire air guide passage is controlled by the cooperation of the outer air guide plate and the inner air guide plate, and when heating or cooling, different adjustment methods are used to change the air direction, thereby improving the heating or cooling effect and better satisfying the needs of the human body.

[0032] In order to make the above objects, features and advantages of the present invention more clear and understandable, the present invention will be described in more detail below with reference to FIGS.

[0033] An embodiment of the present invention discloses an air conditioner. Referring to Figure 1, the air conditioner 100 includes a housing 110 and an outer air guide plate 130. The housing 110 has an air outlet 111. The outer air guide plate 130 is rotatably mounted on the outer wall of the housing 110 to guide air through the air outlet 111, and the mounting position of the outer air guide plate 130 corresponds to the position of the air outlet 111. A pivot shaft 131 is mounted on one side of the outer air guide plate 130, and the pivot shaft 131 is mounted outside the air outlet 111 and located above the air outlet 111. The outer air guide plate 130 is rotatably mounted on the outer wall of the housing 110 via the pivot shaft 131. The length of the outer air guide plate 130 is greater than the length of the air outlet 111 and / or the width of the outer air guide plate 130 is greater than the width of the air outlet 111.

[0034] Because the outer air guide plate 130 is rotatably mounted on the outer wall of the housing 110, its rotation process and rotation angle can be observed, allowing the user to quickly determine whether the air guide angle of the outer air guide plate 130 is adjusted to a desired angle. Furthermore, because the outer air guide plate 130 is mounted outside the air outlet 111, its size is not limited by the size of the air outlet 111 and can be adjusted to a larger size, thereby achieving a better air guide effect. Because the length and / or width of the outer air guide plate 130 are larger than those of the air outlet 111, the outer air guide plate 130 can completely block the air outlet 111 and all of the airflow at the air outlet 111 can be guided by the outer air guide plate 130, thereby improving the air guide effect of the outer air guide plate 130 and reducing dust that enters the air outlet 111 when the air conditioner 100 is not in use, thereby extending the service life of the air conditioner 100.

[0035] A rotating part 113 is provided on the outer wall of the housing 110 at a position corresponding to the top of the air outlet 111, and a rotating shaft 131 is rotatably engaged with the rotating part 113. In this embodiment, in order to increase the rotation frequency of the outer air guide plate 130 and prevent condensation from forming on the outer wall of the housing 110, a groove is provided in the rotating part 113, and the rotating shaft 131 provided on the outer air guide plate 130 is fitted into the groove and rotatably engaged with the groove.

[0036] By installing the rotating shaft 131 and the groove, the external air guide plate 130 is always installed in close contact with the groove when rotating, and the air blown from the air outlet 111 is guided along the external air guide plate 130, making it less likely to come into contact with the outer wall of the housing 110 at the rotating point.

[0037] To further improve the utilization rate of the external air guide plate 130, in this embodiment, the grooves are connected to the upper edge of the air outlet 111 and extend parallel to the extending direction of the upper edge of the air outlet 111. By connecting to the upper edge of the air outlet 111 and extending parallel to it, the external air guide plate 130 can ensure a wider area for providing the air guide effect after being attached to the grooves, and the air guide utilization rate of the external air guide plate 130 is further improved.

[0038] After the external air guide plate 130 is attached to the groove, it can completely cover the housing 110 in the horizontal direction and prevent any gaps from forming on the surface of the housing 110 that could cause condensation. To ensure this, in this embodiment, one end of the groove is opened on one horizontal end wall of the housing 110 and the other end of the groove extends to the other horizontal end wall of the housing 110. That is, the groove passes through both ends of the housing 110 in the horizontal direction.

[0039] After the external air guide plate 130 is installed in the groove, it must be able to rotate smoothly, and it must also ensure a tight fit between the external air guide plate 130 and the housing 110 without creating an excessively large gap. In this embodiment, the cross section of the groove is semicircular.

[0040] The pivot shaft 131 is fitted into the groove, thereby realizing a rotatable engagement between the external air guide plate 130 and the housing 110, and since the groove is recessed into the outer wall of the housing 110, protrusion of the connection point between the external air guide plate 130 and the housing 110 is avoided, improving the aesthetics of the entire air conditioner 100.

[0041] To ensure the dew condensation prevention effect, the lengths of the rotating shaft 131 and the outer air guide plate 130 correspond to the length of the groove and are both greater than the length of the air outlet 111. That is, when the rotating shaft 131 is fitted into the groove, both ends of the rotating shaft 131 are flush with the end walls of the groove, respectively, and both ends in the length direction of the outer air guide plate 130 are flush with the end walls of the groove, respectively.

[0042] Referring to Figure 1, air conditioner 100 further includes an air guide mechanism, which is installed in housing 110 and, together with outer air guide plate 130, is surrounded by an air guide passage that changes the air flow direction, thereby guiding the air at air outlet 111. In the prior art, the air flow direction is fixed in the direction of air outlet 111 and is guided only by outer air guide plate 130, without changing the air flow direction. By installing the air guide mechanism, the air guide mechanism and outer air guide plate 130 work together to change the air flow direction in a direction that provides the optimal effect, allowing air conditioner 100 to achieve the optimal effect during use and meeting the user's needs.

[0043] The air guide mechanism includes an inner air guide plate 150, which is rotatably installed in the housing 110, and the outer air guide plate 130 and the inner air guide plate 150 are both surrounded by an air guide passage to guide the air that flows through the air outlet 111. The outer air guide plate 130 and the inner air guide plate 150 work together. The inner air guide plate 150 can be flexibly rotated following the outer air guide plate 130, thereby achieving the purpose of changing the air direction.

[0044] The inner air guide plate 150 is rotatably installed on a side wall of the air outlet 111 that is away from the outer air guide plate 130. A rotatable crank arm 151 is installed on one side of the inner air guide plate 150, and the end of the rotatable crank arm 151 that is away from the inner air guide plate 150 is rotatably connected to the side wall of the air outlet 111 that is away from the outer air guide plate 130. The rotatable crank arm 151 widens the rotation angle range of the inner air guide plate 150, allowing the inner air guide plate 150 to rotate completely out of the air outlet 111 and obtain a larger air guide angle.

[0045] 2, the maximum air blocking area of ​​the outer air guide plate 130 is larger than the maximum air blocking area of ​​the inner air guide plate 150. When the air conditioner 100 is in the off state, the inner air guide plate 150 is housed in the air outlet 111, and the outer air guide plate 130 shields the air outlet 111. This prevents the outer air guide plate 130 and the inner air guide plate 150 from interfering with each other, and also provides a certain level of protection for the inner air guide plate 150 even in the off state.

[0046] 2 and 3, the outer air guide plate 130 and the inner air guide plate 150 are both installed in an arc shape, and when the air conditioner 100 switches from an off state to a heating mode, the inner air guide plate 150 rotates to the outside of the air outlet 111, and the outer air guide plate 130 rotates by a first angle, and the outer air guide plate 130 and the inner air guide plate 150 are surrounded by an air guide passage that faces diagonally downward, causing the airflow blown out from the air outlet 111 to flow diagonally downward along the side of the outer air guide plate 130 that is closer to the inner air guide plate 150, and at this time, the concave arc surface of the outer air guide plate 130 faces the concave arc surface of the inner air guide plate 150. The outer air guide plate 130 and the inner air guide plate 150 are both installed in an arc shape, with the concave surface of the outer air guide plate 130 facing the side of the outer air guide plate 130 closer to the air outlet 111, and the concave surface of the inner air guide plate 150 facing the side of the inner air guide plate 150 closer to the air outlet 111.

[0047] In the prior art, the air guide plate is installed inside the air outlet 111, so its air guide dimensions are limited by the dimensions of the air outlet 111, limiting its air guide effect. When the air conditioner 100 is operating in heating mode, hot air immediately rises up after being blown out of the air outlet 111, causing a large amount of hot air to gather at the top of the room, resulting in a user's head being hot and their feet being cold, reducing the overall heating effect for the room. In this embodiment, the outer air guide plate 130 is installed outside the housing 110, so its dimensions are not limited by the dimensions of the air outlet 111. This allows it to guide all of the air coming out of the air outlet, providing a greater hot air downward pressure effect and improving the overall heating effect for the room. Furthermore, the outer air guide plate 130 is an arc-shaped plate with drooping ends, which more effectively downward pressures the hot air.

[0048] 2 to 4, when the air conditioner 100 switches from an off state to the cooling mode, the inner air guide plate 150 rotates to the outside of the air outlet 111, and the outer air guide plate 130 rotates by a second angle, and at this time, the concave arc surface of the outer air guide plate 130 faces the concave arc surface of the inner air guide plate 150, the outer air guide plate 130 and the inner air guide plate 150 are surrounded by a substantially horizontal air guide passage, and the second angle is greater than the first angle.

[0049] Because the airflow distribution of hot air and cold air is different, the cold air needs to be transported farther to improve the cooling effect. Because the outer air guide plate 130 is installed outside the housing 110, its dimensions are not limited by the dimensions of the air outlet 111 and can be arranged with a longer dimension, ensuring that the cold air is blown out farther and improving the cooling effect. In cooling mode, the inner air guide plate 150 is an arc-shaped plate with raised ends, which further contributes to the long-distance transport of cold air.

[0050] In summary, in the air conditioner 100 of this embodiment, in actual application, the outer air guide plate 130 is installed on the outer wall of the housing 110, so its rotation process and rotation angle are visible, and the user can quickly determine whether the outer air guide plate 130 is adjusted to the desired angle by visual observation during the air guide angle adjustment process, ensuring a good user experience. Moreover, because the outer air guide plate 130 is installed outside the air outlet 111, it can be adjusted to a larger size, thereby achieving a better air guide effect and preventing condensation from occurring.

[0051] The principle of operation of the embodiment of the present invention is that when air conditioner 100 needs to be used, it is started, and at this time, outer air guide plate 130 rotates and unfolds, and after outer air guide plate 130 is unfolded, inner air guide plate 150 rotates and unfolds, thereby opening an air guide passage between outer air guide plate 130 and inner air guide plate 150. When operating in heating mode, outer air guide plate 130 and inner air guide plate 150 rotate to form a hot air downward pressure passage, causing the airflow blown out from air outlet 111 to flow obliquely downward, improving the heating effect. When operating in cooling mode, outer air guide plate 130 and inner air guide plate 150 rotate to form a cool air upward passage, allowing the airflow blown out from the air outlet to transport cool air over long distances, improving the cooling effect. When the air conditioner 100 is finished being used, the air conditioner 100 is turned off, and at this time, the inner air guide plate 150 first rotates and returns to the inside of the housing 110 , and then the outer air guide plate 130 rotates and covers the air outlet 111 .

[0052] The above are preferred embodiments of the present invention, and do not limit the scope of protection of the present invention based on them. Therefore, any equivalent modifications made based on the structure, shape, and principle of the present invention should be included within the scope of protection of the present invention.
