Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioning indoor unit and also to an air conditioner using the air conditioning indoor unit. Background Art

[0002] At present, most air conditioners on the market are wall-mounted air conditioners, which are mainly used in rooms with small areas. Using air conditioners will cause the human body to have a significant sense of wind, and the direct blowing of cold wind can easily cause discomfort to the human body. Traditional air conditioners can reduce the discomfort of direct blowing of cold wind by adopting the upper air outlet method. Although the upper air outlet method of the air conditioner has a better blowing feeling than the lower air outlet method, it cannot completely avoid direct blowing of cold wind. Traditional air conditioners can also use air conditioner wind shields. Users can buy wind shields by themselves and install them at the air outlet of the air conditioner to cover the air outlet. The cold air can be sent out from the multiple micropores designed on the wind shield panel. Although it can make the air outlet more uniform and reduce the stiff wind feeling, it will cause a large loss of air volume, reduce the heat exchange rate inside the room, and make the user experience poor. There is also a wall-mounted air conditioner with a second air guide plate designed on the air guide plate. The second air guide plate is provided with a plurality of ventilation holes penetrating in the thickness direction thereof. The wind in the shell can pass through the ventilation holes of the second air guide plate and blow into the room. Although it can achieve non-sensing wind, it reduces the wind speed of the air outlet, which reduces the indoor heat exchange efficiency.

[0003] Therefore, it is necessary to consider how to solve the problem of obvious airflow from the air conditioner and strong wind sensation on the human body while ensuring heat exchange efficiency. Utility Model Content

[0005] The second object of the utility model is to provide an air conditioner which can solve the problem of direct air blowing from the air outlet and ensure indoor heat exchange efficiency.

[0006] In order to achieve the above-mentioned first purpose, the air-conditioning indoor unit provided by the utility model includes a shell body, in which an air duct is arranged; a wind disturbance channel is also arranged in the shell body, and the wind disturbance inlet and the wind disturbance outlet of the wind disturbance channel are both communicated with the air duct, the wind disturbance outlet is located on the side close to the air outlet of the air duct, and the wind disturbance inlet is located on the side away from the air outlet of the air duct; a wind disturbance device for changing the air outlet direction of the wind disturbance outlet is installed at the wind disturbance outlet.

[0007] It can be seen from the above scheme that the air-conditioning indoor unit of the utility model is provided with a wind disturbance channel in the shell, and a wind disturbance device for changing the air outlet direction of the wind disturbance outlet is installed at the wind disturbance outlet, so that the wind disturbance device can adjust the flow direction of the disturbed wind, thereby disturbing the air outlet direction of the air outlet of the air-conditioning indoor unit, reducing the wind feeling, and at the same time, reducing the air outlet obstruction, ensuring the heat exchange efficiency inside the room, and effectively meeting the user's demand for a comfortable indoor environment.

[0008] In a further solution, the wind-disturbing device includes a wind-disturbing blade and a driving device, and the driving device drives the wind-disturbing blade to swing.

[0010] In a further solution, the length direction of the wind-disturbing air outlet is parallel to the length direction of the air outlet of the air duct; and the rotating shaft of the wind-disturbing blade is arranged along the length direction of the wind-disturbing air outlet.

[0011] It can be seen that the rotating shaft of the wind-disturbing blade is arranged along the length direction of the wind-disturbing outlet, which can optimize the wind-disturbing outlet direction and improve the wind-disturbing effect.

[0012] In a further scheme, the wind disturbance channel includes an air inlet portion, a duct portion and an air outlet portion, the air inlet portion is connected to the first end of the duct portion, and the air outlet portion is connected to the second end of the duct portion; the wind disturbance inlet is located at the air inlet portion, and the wind disturbance outlet is located at the air outlet portion; the air flow channel of the air inlet portion gradually decreases from the wind disturbance inlet portion toward the duct portion.

[0013] It can be seen that the air flow channel of the air inlet part gradually decreases from the disturbed air inlet to the duct part, which can increase the air inlet area and ensure diversion from the cross-flow fan blades. At the same time, the disturbed air inlet is wide at first and narrow at the end in order to increase the air inlet area and air volume, and ensure that the disturbed airflow is sufficient to disturb the outlet airflow. The duct part is narrowed in order to speed up the air flow rate in the duct part, so that the disturbed airflow can pass smoothly and quickly, thereby achieving a certain pressurization effect.

[0014] In a further solution, the air flow channel of the air outlet portion gradually increases in size from the duct portion toward the wind-disturbing outlet.

[0015] It can be seen that the air flow channel of the air outlet portion gradually increases from the pipe portion to the direction of the wind disturbance outlet, making the air outlet portion narrow at first and then wide, in order to increase the disturbed air outlet area, and provide an installation position for the spoiler blades and adjust the spoiler angle, thereby maximizing the wind disturbance effect.

[0016] In a further solution, the number of the wind-disturbing channels is more than two; and the more than two wind-disturbing air outlets are arranged along the length direction of the air outlet.

[0017] It can be seen that setting up multiple wind disturbance channels and arranging the wind disturbance outlets along the length direction of the outlets can help to individually control the wind disturbance direction of each wind disturbance channel, increase the diversity of wind disturbance, and improve the wind disturbance effect.

[0018] In a further solution, a lower cover plate detachably mounted on the shell is provided on one side of the air duct close to the air outlet; and the wind-disturbing air outlet is provided on the lower cover plate.

[0019] It can be seen that a detachable lower cover is provided on the side of the air duct close to the air outlet to facilitate subsequent maintenance or cleaning of the wind disturbance channel.

[0021] It can be seen that the second end of the fixed column is engaged with the edge of the lower cover plate by setting a clamping part, and when the lower cover plate is installed, the clamping part can clamp the lower cover plate tightly to avoid the lower cover plate from shaking when the flow rate of the wind disturbance throttling is large. At the same time, the second end of the fixed column is provided with a avoidance groove on the side facing away from the clamping part, and when the lower cover plate is disassembled, the avoidance groove can be turned to the direction of the lower cover plate, so that the lower cover plate can be loosened. Since the installation space of the fixed column is small, this structural setting can facilitate operation.

[0022] In a further solution, the shell is provided with a mounting groove, and a limiting portion is provided on the inner peripheral wall of the mounting groove; a limiting ring is provided on the outer peripheral wall of the fixing column, and the limiting ring cooperates with the limiting portion in a limiting manner.

[0023] It can be seen that the fixing column can be installed in the installation groove by arranging the limiting part and the limiting ring to cooperate with each other.

[0038] In this embodiment, a wind disturbance channel 3 is further provided in the housing 1, and the wind disturbance inlet 311 and the wind disturbance outlet 331 of the wind disturbance channel 3 are both communicated with the wind duct 2, the wind disturbance outlet 331 is located on the side close to the outlet of the wind duct 2, and the wind disturbance inlet 311 is located on the side away from the outlet 4 of the wind duct 2. A wind disturbance device 5 for changing the outlet direction of the wind disturbance outlet 331 is installed at the wind disturbance outlet 331.

[0039] In this embodiment, the wind disturbance channel 3 includes an air inlet 31, a duct portion 32 and an air outlet 33.

The wind disturbance inlet 311 is located at the air inlet 31, and the wind disturbance outlet 331 is located at the air outlet 33. The air flow channel of the air inlet 31 gradually decreases from the wind disturbance inlet 311 to the duct portion 32, and the air flow channel of the air outlet 33 gradually increases from the duct portion 32 to the wind disturbance outlet 331. The airflow passage of the air inlet 31 gradually decreases from the wind-disturbing air inlet 311 to the direction of the duct 32, which can increase the air inlet area and ensure diversion from the cross-flow blades. At the same time, the air inlet 31 is first wide and then narrowed in order to increase the air inlet area and air volume, and ensure that the wind-disturbing airflow is sufficient to disturb the airflow outflow. The duct 32 is narrowed in order to speed up the air flow rate in the duct 32, so that the wind-disturbing airflow can pass smoothly and quickly, and achieve a certain pressurization effect. The airflow passage of the air outlet 33 gradually increases from the duct 32 to the direction of the wind-disturbing air outlet 331, so that the air outlet 33 is first narrow and then wide, in order to increase the wind-disturbing outlet area, and to provide an installation position for the wind-disturbing blades, and to adjust the wind-disturbing angle, so as to maximize the wind-disturbing effect.

[0040] In this embodiment, the wind disturbance device 5 includes a wind disturbance blade 51 and a driving device 52, and the driving device 52 drives the wind disturbance blade 51 to swing. Preferably, the driving device 52 is a motor. By setting the driving device 52 to drive the wind disturbance blade 51 to swing, it is helpful to adjust the air outlet direction of the wind disturbance outlet 331.

[0041] The length direction of the wind-disturbing outlet 331 is parallel to the length direction of the outlet 4 of the air duct 2. The rotating shaft of the wind-disturbing blade 51 is arranged along the length direction of the wind-disturbing outlet 331. The rotating shaft of the wind-disturbing blade 51 is arranged along the length direction of the wind-disturbing outlet 331, which can optimize the wind-disturbing outlet direction and improve the wind-disturbing effect.
