Description

Technical Field

[0001] The invention relates to the field of air conditioner accessories, in particular to an adjustable diffuser and an air conditioner. Background Art

[0002] With the continuous improvement of people's living standards, household appliances such as air conditioners have become an indispensable appliance in people's lives and work. Air conditioners are cooling and heating equipment that send cold air or hot air to indoor rooms that need to adjust the temperature through pipes. However, it is not possible to blow the cold air or hot air generated by the air conditioner directly into the user's room through ventilation ducts. Generally, the air outlet of the air conditioner is set on the ceiling and a diffuser is set at the end of the air outlet. Generally, the diffuser disperses the airflow in a fixed direction, which will make the indoor temperature adjustment uneven, the heat exchange efficiency is low, and it cannot meet the human body's requirements for comfort.

[0003] Among them, the diffuser is the terminal air outlet of the air conditioner, which can make the air outflow flow in multiple directions. It is generally used to supply air to large areas such as halls so that the fresh air is evenly distributed, which is convenient for the rapid and uniform mixing of air, and will not produce excessive local wind speed. The main function of the diffuser is to change the direction of air movement, maintain the air flow rate, and enable the air to quickly mix with the indoor air or reach a certain place; in the air-conditioned room, the air discharged by the diffuser will inevitably cause the flow of indoor air after the heat and mass exchange with the indoor air, and different air flow conditions have different temperature adjustment effects. Therefore, the shape and structure of the diffuser need to be based on the air flow temperature and flow characteristics of the corresponding working conditions in different seasons, so that a relatively uniform and stable air flow is formed in the air-conditioned area to meet the human comfort. This is also a technical problem that technicians in this field need to solve. However, the diffuser blade structure improved by others in the prior art is fixed, and the air flow direction is fixed, which leads to excessive concentration of cold wind in summer and ineffective fall of hot wind in winter. It cannot effectively improve the heat exchange efficiency and air flow mixing uniformity, which greatly reduces the human comfort. Summary of the invention

[0004] In view of the above problems existing in the prior art, the object of the present invention is to provide an adjustable diffuser and an air conditioner using the adjustable diffuser to overcome the defects of the prior art and to achieve uniformity of air outflow according to the temperature and corresponding flow characteristics of the air under different working conditions.

[0034] An embodiment of the present invention provides an adjustable diffuser, which is arranged at the end of the air supply duct of the air conditioner, such as Figure 1 and Figure 2As shown, the adjustable diffuser includes: a hot air diffuser cylinder, a cold air guide hole cylinder 3 and a channel conversion component 5, the hot air diffuser cylinder includes a vertically hollow straight cylinder 1 and a guide cylinder 2 arranged at the lower part of the straight cylinder 1 and connected to the straight cylinder 1, wherein the outer surface of the guide cylinder 2 facing the straight cylinder 1 is arranged in an arc shape to guide the blown air; the cold air guide hole cylinder 3 is sleeved on the straight cylinder 1 and a cold air diffuser channel 4 arranged around the straight cylinder 1 is formed between the cold air guide hole cylinder 3 and the straight cylinder 1; the channel conversion component 5 is used to control the air flow of the hot air diffuser cylinder 1 arranged in the straight cylinder 1. The first baffle 9 at the air inlet of the body 1 and the second baffle 10 at the air inlet of the cold air diffusion channel 4, when hot air is blown out from the air outlet, the channel conversion component 5 controls the second baffle 10 to block the air inlet of the cold air diffusion channel 4, controls the first baffle to open, so that the hot air is blown out through the straight cylinder 1 and the inside of the guide cylinder 2; when cold air is blown out from the air outlet, the channel conversion component 5 controls the first baffle 9 to block the air inlet of the straight cylinder 1, controls the second baffle 10 to open, so that the cold air is blown out after passing through the cold air diffusion channel 4 and the outer surface of the guide cylinder 2.

[0035] It can be seen from the above technical scheme that it sets a hot air diffusion cylinder and a cold air guide hole cylinder 4 separated from each other, and sets a first baffle 9 at the air inlet of the straight cylinder 1 of the hot air diffusion cylinder and a second baffle 10 at the air inlet of the cold air diffusion channel 4, so that when hot air is blown out at the air outlet, the channel conversion component 5 controls the second baffle 10 to block the air inlet of the cold air diffusion channel 4, controls one baffle to open, so that the hot air is blown out through the straight cylinder 1 and the guide cylinder 2, and when cold air is blown out at the air outlet, the channel conversion component 5 controls the first baffle 9 to block the air inlet of the straight cylinder 1, controls the second baffle 10 to open, so that the cold air passes through the cold air diffusion channel 4 and is blown after the guide on the outer surface of the guide cylinder 2 That is, the adjustable diffuser can adjust the first baffle 9 and the second baffle 10 according to the different air supply types of the air conditioner in summer or winter, so as to realize the hot air being supplied vertically downward through the straight cylinder 1 and the guide cylinder 2, so that the hot air can reach a farther distance, thereby avoiding the situation in which warm air accumulates in the top space for a long time in winter and cannot be supplied downward. At the same time, the adjustable diffuser can blow out the cold air through the cold air diffusion channel 4 and guide the cold air through the outer surface of the guide cylinder 2, thereby avoiding the situation in which cold air accumulates in the bottom space for a long time in summer and cannot flow evenly and dispersedly in all directions, thereby improving the air mixing uniformity and greatly improving the user experience and comfort.

[0036] In order to better guide the cold air and improve the efficiency of air mixing, Figure 1As shown, in some embodiments of the present invention, the cold air guide hole cylinder 3 is provided with a lower end surface on the side close to the guide cylinder body 2, and a plurality of outlets 6 are provided on the lower end surface, so that the cold air can be blown out through the plurality of outlets 6, thereby increasing the wind speed of the outlet air.

[0037] In order to properly filter the air blown out by the air conditioner and ensure people's health, in some embodiments of the present invention, a filter screen 7 is provided at the lower end of the straight cylinder 1 for filtering the air flowing through.

[0038] Further, in some embodiments of the present invention, Figure 1 As shown, the lower end of the guide cylinder 2 is provided with a guide plate 8 for guiding the air, and the guide plate 8 is provided with a plurality of guide ports, so that when the hot air is guided, the hot air can be blown more directly to the bottom area, thereby improving the efficiency of air mixing.

[0039] Furthermore, in some embodiments of the present invention, Figure 1 As shown, the shape of the internal guide cavity and the outer surface of the guide cylinder 2 is a trumpet shape with a gradually increasing circumference from the upper end connected to the straight cylinder 1 to the end of the guide cylinder 2. On the one hand, it allows the hot air to be blown to the bottom area with a larger area. On the other hand, it enables the outer surface of the guide cylinder 2 to better guide the cold air and minimize the resistance to the flow of cold air.

[0040] In some embodiments of the present invention, the channel conversion component 5 includes a first adjusting member 11 for controlling the first baffle 9 to rotate along a first circle away from the air inlet of the straight cylinder body 1 and a second adjusting member 12 for controlling the second baffle 10 to rotate along a second circle away from the air inlet of the cold air diffusion channel 4, wherein the first adjusting member 11 and the second adjusting member 12 can be adjusted manually, that is, when cold air is needed in summer, the first baffle 9 can be adjusted to a position to block the air inlet of the straight cylinder body 1 through the first adjusting member 11, and the second baffle 10 can be opened through the second adjusting member 12; in winter, the second baffle 10 can be adjusted to a position to block the air inlet of the cold air diffusion channel 4 through the second adjusting member 12, and the first baffle 9 can be opened.

[0041] Of course, in order to improve the adaptability of the adjustable diffuser, in some embodiments of the present invention, a detection component is provided in the channel conversion component 5, and the detection component is used to detect the ambient temperature of the environment in which it is located and the temperature of the air blown out of the air outlet. If after a preset time period, such as after 5 minutes of detection, it can also be 3 minutes or 1 minute, etc., which is not clearly limited here, the ambient temperature is lower than the air temperature, then the second baffle 10 is controlled to block the air inlet of the cold air diffusion channel 4, and the first baffle is controlled to open. If the ambient temperature is greater than the air temperature, then the first baffle 9 is controlled to block the air inlet of the straight cylinder 1, and the second baffle 10 is controlled to open. The ambient temperature detection can be the ambient temperature detected when the air conditioner is turned on or the ambient temperature detected when the air conditioner mode is switched, and the detected air temperature blown out of the air outlet is the temperature detected at the preset time. For the detection after a long time, if the ambient temperature detected first is 28 degrees Celsius, and after 3 minutes, the air temperature blown out of the air outlet is detected to be 22 degrees Celsius, then at this time, the first baffle 9 is controlled to block the air inlet of the straight cylinder 1, and the second baffle 10 is controlled to open. If the first baffle 9 is already in a blocking state, the first baffle 9 is not controlled to move. Similarly, if the second baffle 10 is already opened, the second baffle 10 is not controlled to move. If the ambient temperature detected first is 15 degrees Celsius, and after 3 minutes, the air temperature blown out of the air outlet is detected to be 26 degrees Celsius, the second baffle 10 is controlled to block the air inlet of the cold air diffusion channel 4, and one baffle is controlled to open. At this time, if the first baffle 9 is already in an open state, the first baffle 9 is not controlled to move. Similarly, if the second baffle 10 is already in a blocking state, the second baffle 10 is not controlled to move.

[0042] The present invention further provides an air conditioner, comprising: the above adjustable diffuser, wherein the adjustable diffuser is arranged at the end of an air supply duct of the air conditioner.

[0043] The air conditioner is an air conditioner that adopts the above-mentioned adjustable diffuser, and it has all the beneficial effects of the adjustable diffuser, that is, it can adjust the first baffle 9 and the second baffle 10 of the adjustable diffuser according to the different air supply types of the air conditioner in summer or winter, so as to realize the hot air being supplied in a vertical downward manner through the straight cylinder 1 and the guide cylinder 2, so that the hot air can reach a farther distance, avoiding the situation in which warm air accumulates in the top space for a long time in winter and cannot be supplied downward. At the same time, its adjustable diffuser can blow out cold air through the cold air diffusion channel 4 and guide the cold air through the outer surface of the guide cylinder 2, thereby avoiding the situation in which cold air accumulates in the bottom space for a long time in summer and cannot flow evenly and dispersedly in all directions, thereby improving the air mixing uniformity and greatly improving the user experience and comfort.

[0044] Furthermore, in some embodiments of the present invention, the adjustable diffuser includes a controller, which is communicatively connected to the processor of the air conditioner and can obtain mode information of the air conditioner through the processor, and control the first baffle 9 of the adjustable diffuser to block and open the air inlet of the straight cylinder body 1 of the adjustable diffuser and the second baffle 10 to block and open the air inlet of the cold air diffusion channel 4 of the adjustable diffuser according to the mode information, thereby further improving the adaptability of the adjustable diffuser and the air conditioner, having a certain intelligent effect, being more convenient for users to use, and improving the user experience.

[0045] In addition, in order to further improve the practicality of the air conditioner, in some embodiments of the present invention, if the mode information detected by the controller is a fresh air model, the controller controls the first baffle 9 and the second baffle 10 to be in a semi-open state, wherein the semi-open state includes the first baffle 9 blocking 40%-60% of the cross-sectional area of ​​the air inlet of the straight cylinder 1, and the second baffle 10 blocking 40%-60% of the cross-sectional area of ​​the air inlet of the cold air diffusion channel 4. That is, the air conditioner using the above-mentioned adjustable diffuser can adapt to the air supply under different seasonal conditions and change the air supply direction; not only can the air supply mode be switched between winter and summer, but also the first baffle 9 and the second baffle 10 can be controlled in a semi-open state in the transition season, so that the fresh air is blown out from the outlet 6 and the guide cylinder 2, and better mixed with the indoor air. In addition, the air supply requirements under different working conditions in summer, winter and transition seasons can be met, the air flow mixing uniformity is increased, and the human comfort is improved.
