An air conditioner

Abstract

This invention provides an air conditioner, including a housing, an air outlet, an air inlet, an indoor unit heat exchanger, a fan, and a baffle plate. The baffle plate is rotatably connected to the housing. The baffle plate is configured to rotate to the air inlet and cover it, and also to rotate to contact and compress an air guide plate. The air guide plate has multiple air outlets, each containing a first flexible baffle and a second flexible baffle. The first and second flexible baffles are configured to separate and expose the air outlets, and also to contact and close them. When the air conditioner is not running, the baffle plate rotates to the air inlet and covers it, closing the air outlets, and the air guide plate covers the air outlets. When the air conditioner is running, the baffle plate rotates towards the air guide plate. The air guide plate, compressed by the baffle plate, compresses the first and second flexible baffles, exposing the air outlets. Air flows through the air outlets, disperses, and is then blown out, reducing the draft and improving user comfort.

Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0002] Air conditioners are a very common household appliance, bringing users great comfort. Therefore, users are placing increasingly higher demands on the overall performance of air conditioners, especially regarding the airflow experience and quality of the indoor unit. Air conditioners tend to blow directly onto users, particularly when operating in cooling mode, where the cold air blown directly onto the body can easily cause discomfort. Furthermore, the air inlet is located on the top of the air conditioner, leading to dust accumulation there and severely affecting the cleanliness of the delivered air.

[0003] To address the issues of direct airflow from air conditioners and dust accumulation, existing air conditioner indoor units include a casing, an air guide plate, and a multi-functional panel. The multi-functional panel includes a first air deflector and a second air deflector. The first air deflector has a first air diffuser hole, and the second air deflector has a second air diffuser hole. The first and / or second air deflectors are designed to move to the air inlet for dust prevention, and to disperse the airflow when they move to the vicinity of the air outlet. While this avoids both direct airflow and dust accumulation at the air outlet, it requires three panels—the air guide plate, the first air deflector, and the second air deflector—in the indoor unit, increasing costs. Summary of the Invention

[0004] In view of this, the present invention aims to provide an air conditioner that solves the problems of increased cost, poor air delivery experience, and easy dust accumulation in existing air conditioners.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] An air conditioner includes a housing, an air outlet, an air inlet, an indoor unit heat exchanger, and a fan. The air outlet is located at the lower front of the housing, and the air inlet is located at the top of the housing. A guide vane is provided at the air outlet. The air conditioner also includes a baffle plate, which is rotatably connected to the housing. The baffle plate is configured to rotate to the air inlet and cover it. The baffle plate is also configured to rotate to contact the guide vane and compress the guide vane with a first strength. The guide vane has multiple air outlets, each of which includes a first flexible baffle and a second flexible baffle. The first and second flexible baffles are configured to separate and expose the air outlet. The first and second flexible baffles are also configured to contact and close the air outlet. The guide vane, the first flexible baffle, and the second flexible baffle are all flexible components. When the air conditioner is not running, the baffle rotates upwards to cover the air inlet, preventing dust from entering the casing. Due to the contact between the first and second flexible baffles, the air outlet is closed, and the air guide plate covers the air outlet, preventing dust from entering the casing. The baffle and air guide plate effectively address the issue of dust easily entering the casing, preventing dust from affecting airflow and cooling / heating performance, thus improving the user experience. When the air conditioner is running, the baffle rotates downwards towards the air guide plate. The air guide plate, compressed by the baffle, forces the first and second flexible baffles to expose the air outlet. Air from inside the casing is then dispersed and blown out through the air outlet, reducing the draft and improving user comfort.

[0007] Furthermore, after the baffle plate rotates to contact the air guide plate, it can continue to rotate towards the air guide plate and compress the air guide plate with a second intensity greater than the first intensity. This causes the air guide plate to be compressed to different degrees. The degree of compression of the air guide plate can be used to change the exposure level of the air outlet, i.e., the size of the air outlet, thereby changing the intensity of the airflow to meet different user needs.

[0008] Furthermore, the left end of the first flexible baffle is a first connecting end, and the right end is a first air guide end. The right end of the second flexible baffle is a second connecting end, and the left end is a second air guide end. The first connecting end is connected to the air outlet and is used to connect the first flexible baffle to the air guide plate. The second connecting end is connected to the air outlet and is used to connect the second flexible baffle to the air guide plate. The first air guide end and the second air guide end are in contact to close the air outlet. Under the squeezing action of the baffle, the first air guide end and the second air guide end separate, exposing the air outlet. Multiple air outlets can disperse the airflow, thereby reducing the feeling of wind.

[0009] Furthermore, the multiple air outlets are arranged in an array on the air guide plate to ensure effective air dispersion and uniform airflow.

[0010] Furthermore, the wind deflector is rotatably connected to the housing via a fixed base. The wind deflector includes a support and a rotating shaft, with the rotating shaft connected to the wind deflector via the support. The support increases the contact area between the support and the wind deflector, improving the tightness of the connection between the rotating shaft and the wind deflector.

[0011] Furthermore, the fixed base includes a rotating rod, side plates, and a crossbar. Two side plates are provided and are arranged opposite each other. A side plate is connected to each of the left and right sides of the crossbar for mounting the crossbar onto the fixed base. One side of the rotating rod is rotatably connected to the crossbar, and the other side is connected to a rotating shaft. The rotating rod rotates around the crossbar, thereby driving the wind deflector to rotate.

[0012] Furthermore, the side of the rotating rod facing the crossbar is the second mounting part, and the side of the rotating rod away from the crossbar is the first mounting part. The second mounting part is sleeved on the outside of the crossbar, and the first mounting part is sleeved on the outside of the rotating shaft. The first mounting part facilitates the connection and assembly of the rotating shaft and the fixed seat, and the second mounting part facilitates the connection and assembly of the rotating rod and the crossbar, as well as the rotation of the rotating rod.

[0013] Furthermore, two rotating shafts are provided and symmetrically distributed on the left and right sides of the wind deflector, and two fixed seats are provided accordingly to facilitate the rotational stability of the wind deflector.

[0014] Furthermore, the side plate and the housing are connected for mounting the mounting bracket onto the indoor unit of the air conditioner.

[0015] Furthermore, the mounting base also includes a positioning rod, which is located on the upper side of the mounting base. The left and right sides of the positioning rod are connected to the side plates respectively. When the rotating rod is rotated upwards until the wind deflector is at the air inlet, the rotating rod will stop rotating in the direction of the positioning rod upon contact with it. This ensures that the wind deflector is at and covers the air inlet, preventing displacement of the wind deflector and improving the dustproof effect of the air conditioner. Simultaneously, the positioning rod and rotating rod enhance the overall strength of the mounting base, preventing deformation of the side plates during prolonged use.

[0016] Compared with the prior art, the air conditioner of the present invention has the following advantages:

[0017] (1) By using the structure of the air guide plate and the combination of the air guide plate and the wind deflector, the dual purpose of dust prevention and wind reduction can be achieved, and costs can be saved.

[0018] (2) During the rotation of the baffle, the baffle is pressed against the air guide plate with different strengths, thereby changing the exposure degree of the air outlet and the intensity of the airflow to meet the different needs of users.

[0019] (3) The air outlet is covered by the air guide plate and the air inlet is covered by the air baffle plate to prevent dust from entering the interior of the air conditioner's indoor unit casing from the air outlet and air inlet, thus ensuring clean air output and heat exchange effect.

Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0031] Example 1

[0032] like Figure 1 As shown, the air conditioner of the present invention includes a housing 6, an air outlet 3, an air inlet 4, an indoor unit heat exchanger, and a fan. The air outlet 3 is located at the lower front of the housing 6, and the air inlet 4 is located at the top of the housing 6. Outside air enters the interior of the housing 6 through the air inlet 4, exchanges heat with the heat exchanger inside the housing 6, and is then blown out from the air outlet 3 by the action of the fan, thereby changing the indoor temperature.

[0033] like Figure 2-5 As shown, an air guide plate 2 is provided at the air outlet 3. The air conditioner also includes a baffle plate 1, which is rotatably connected to the housing 6. The baffle plate 1 is configured to rotate to the air inlet 4 and cover the air inlet 4. The baffle plate 1 is also configured to rotate to contact the air guide plate 2 and compress the air guide plate 2 with a first strength. The air guide plate 2 is provided with multiple air outlets 23. Each air outlet 23 includes a first flexible baffle 21 and a second flexible baffle 22. The first flexible baffle 21 and the second flexible baffle 22 are configured to separate and expose the air outlet 23. The first flexible baffle 21 and the second flexible baffle 22 are also configured to contact and close the air outlet 23. The air guide plate 2, the first flexible baffle 21 and the second flexible baffle 22 are all flexible components. Preferably, the air guide plate 2, the first flexible baffle 21 and the second flexible baffle 22 are made of rubber. When the air guide plate 2 is not compressed, the first flexible baffle 21 and the second flexible baffle 22 are in contact, and the air outlet 23 is closed. When the air guide plate 2 is compressed, the first flexible baffle 21 and the second flexible baffle 22 are separated by compression, and the air outlet 23 is opened. When the baffle plate 1 is away from the air guide plate 2, the air guide plate 2 is not compressed. Because the air guide plate 2 is a flexible component, the baffle plate 1 can contact and compress the air guide plate 2.

[0034] When the air conditioner is not in operation, the baffle 1 rotates upwards to the air inlet 4 and covers it, preventing dust from entering the housing 6 through the air inlet 4. Due to the contact between the first flexible baffle 21 and the second flexible baffle 22, the air outlet 23 closes, and the air guide plate 2 covers the air outlet 3, preventing dust from entering the housing 6 through the air outlet 3. The baffle 1 and air guide plate 2 effectively address the problem of dust easily entering the housing 6, preventing dust from affecting the airflow and cooling / heating performance, thus improving the user experience. In existing technologies, to reduce the airflow intensity of an air conditioner, air outlets 23 are typically created directly on the air guide plate 2, using multiple distributed air outlets 23 to disperse and weaken the airflow. While this reduces the perceived airflow, when the air conditioner is not in use, the air outlets 23 connect the indoor environment and the interior of the indoor unit, making it easy for dust to enter the housing 6 through the air outlets 23, which is detrimental to the lifespan of the air conditioner and the user's health. This invention effectively avoids this problem by using the first flexible baffle 21 and the second flexible baffle 22 to close the air outlets 23. When the air conditioner is running, the deflector 1 moves downward and rotates towards the air guide 2. After the air guide 2 is squeezed by the deflector 1, the first flexible baffle 21 and the second flexible baffle 22 are squeezed, thus exposing the air outlet 23. The air inside the housing 6 reaches the air outlet 23 through the air outlet 3 and is dispersed before being blown out, thereby reducing the feeling of wind and improving the user's comfort.

[0035] Furthermore, after the baffle 1 rotates to contact the air guide plate 2, it can continue to rotate towards the air guide plate 2 and compress the air guide plate 2 with a second intensity greater than the first intensity, causing the air guide plate 2 to be compressed to different degrees. The degree of compression of the air guide plate 2 can change the exposure of the air outlet 23, thereby changing the intensity of the airflow to meet different user needs. The smaller the exposed area of ​​the air outlet 23, the weaker the airflow, avoiding discomfort caused by the air conditioner blowing directly on the user. The air conditioner of the present invention can adjust the intensity of the airflow by utilizing the structure of the air guide plate 2 itself and the cooperation of the baffle 1 and the air guide plate 2. The structure is simple and can meet different user needs.

[0036] Furthermore, the left end of the first flexible baffle 21 is a first connecting end 211, and the right end is a first air guide end 212. The right end of the second flexible baffle 22 is a second connecting end 221, and the left end is a second air guide end 222. The first connecting end 211 is connected to the air outlet 23 to connect the first flexible baffle 21 to the air guide plate 2. The second connecting end 221 is connected to the air outlet 23 to connect the second flexible baffle 22 to the air guide plate 2. The first air guide end 212 and the second air guide end 222 are in contact to close the air outlet 23. Under the squeezing action of the baffle plate 1, the first air guide end 212 and the second air guide end 222 separate, exposing the air outlet 23. Multiple air outlets 23 can disperse the airflow, thereby reducing the feeling of wind.

[0037] Furthermore, the multiple air outlets 23 are arranged in an array on the air guide plate 2 to ensure effective air dispersion and uniform airflow. Since the air guide plate 2 has multiple air outlets 23, the use of the first flexible baffle 21 and the second flexible baffle 22 helps to improve the overall strength of the air guide plate 2 and extend its service life. Even further, in the width direction of the air guide plate 2, i.e., the vertical direction, adjacent air outlets 23 in the same row contact each other, reducing the distance between adjacent air outlets 23. When the baffle plate 1 rotates to contact the air guide plate 2, the baffle plate 1 is located on the upper side of the air guide plate 2, i.e., the baffle plate 1 presses against the air guide plate 2 from above, and adjacent air outlets 23 in the same row contact each other, which helps to ensure that the first flexible baffle 21 and the second flexible baffle 22, which are far from the baffle plate 1, are also subjected to a compressive effect.

[0038] Furthermore, the main body of the casing 6 is rectangular, and both the air outlet 3 and the air inlet 4 are rectangular to increase the air volume of the indoor unit of the air conditioner and improve the cooling or heating efficiency. The shape of the air guide plate 2 matches the shape of the air outlet 3, and the shape of the baffle plate 1 matches the shape of the air inlet 4.

[0039] Example 2

[0040] like Figure 5-6 As shown, the wind deflector 1 is rotatably connected to the housing 6 via a fixed base 5. The wind deflector 1 includes a support 11 and a rotating shaft 12, and the rotating shaft 12 is connected to the wind deflector 1 via the support 11. By providing the support 11, the contact area between the support 11 and the wind deflector 1 is increased, thereby improving the tightness of the connection between the rotating shaft 12 and the wind deflector 1. The mounting base 5 includes a rotating rod 51, side plates 52, and a crossbar 53. Two side plates 52 are provided and arranged opposite each other. The side plates 52 are connected to the housing 6 and are used to install the mounting base 5 onto the indoor unit of the air conditioner. A side plate 52 is connected to each of the left and right sides of the crossbar 53, allowing the crossbar 53 to be mounted onto the mounting base 5. One side of the rotating rod 51 is rotatably connected to the crossbar 53, and the other side is connected to the rotating shaft 12. The rotating rod 51 rotates around the crossbar 53, thereby driving the wind deflector 1 to rotate. This allows the wind deflector 1 to rotate to the air inlet 4 to cover the air inlet 4 for dust prevention, and also allows the wind deflector 1 to rotate to the air guide plate 2 to disperse the airflow. The rotating rod 51 is connected to a motor, which drives the rotating rod 51 to rotate. The motor provides the power for the rotation of the rotating rod 51.

[0041] Furthermore, the side of the rotating rod 51 facing the crossbar 53 is a second mounting part 56, and the side of the rotating rod 51 away from the crossbar 53 is a first mounting part 55. The second mounting part 56 is sleeved on the outside of the crossbar 53, and the first mounting part 55 is sleeved on the outside of the rotating shaft 12. The first mounting part 55 facilitates the connection and assembly of the rotating shaft 12 and the fixed seat 5, and the second mounting part 56 facilitates the connection and assembly of the rotating rod 51 and the crossbar 53, as well as the rotation of the rotating rod 51.

[0042] Furthermore, two rotating shafts 12 are provided, and they are symmetrically distributed on the left and right sides of the wind deflector 1 (in Figure 5 (Only one side of the rotating shaft 12 is shown in the image). Correspondingly, two fixing bases 5 are also provided to improve the rotational stability of the wind deflector 1.

[0043] Furthermore, the fixed base 5 also includes a positioning rod 54, which is disposed on the upper side of the fixed base 5. The left and right sides of the positioning rod 54 are respectively connected to the side plate 52. The positioning rod 54 is used to position the rotation angle of the rotating rod 51. When the rotating rod 51 rotates upward until the baffle plate 1 is at the air inlet 4, the rotating rod 51 cannot continue to rotate in the direction towards the positioning rod 54 after hitting the positioning rod 54, ensuring that the baffle plate 1 is at the air inlet 4 and covers the air inlet 4, preventing the baffle plate 1 from shifting position and improving the dustproof effect of the air conditioner. At the same time, the positioning rod 54 and the rotating rod 51 can improve the overall strength of the fixed base 5 and prevent the side plate 52 from deforming during long-term use.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
