Description

Technical Field

[0001] This utility model relates to the field of air conditioning, and in particular to an air temperature detection structure for an indoor unit of an air conditioner. Background Technology

[0002] A fresh air conditioner is an intelligent air conditioner that achieves indoor-outdoor air exchange through a built-in fresh air system, combining temperature control and air purification functions. Air conditioners with a fresh air function can deliver fresh outdoor air into the room, effectively improving the air quality of a closed indoor environment. Generally, a fresh air conditioner includes two main air channels: a fresh air channel and an intake air channel. The fresh air channel is used to introduce fresh outdoor air into the room, while the intake air channel introduces indoor air into the indoor unit to regulate the air temperature.

[0003] When a fresh air conditioning system is operating, it needs to obtain the temperature of the introduced fresh air as a parameter for adjusting the system's operation. Current methods obtain the fresh air temperature by using a temperature sensor located on the outdoor unit. However, if the outdoor unit is installed in a location with louvers, and the introduced fresh air is exposed to the outside, the louvers will inevitably obstruct the view, leading to a significant difference between the temperature reading from the outdoor unit's temperature sensor and the actual temperature of the introduced fresh air. This renders the temperature reading from the outdoor unit unusable as the fresh air's detection temperature. Furthermore, if a separate temperature sensor is installed for the fresh air duct, it will remain idle when the fresh air is not in use or when temperature monitoring is not required for extended periods, resulting in low utilization of the temperature sensor and increased overall system cost. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an air temperature detection structure for an air conditioning indoor unit that can detect the air temperature in the fresh air duct and the air intake duct separately using the same temperature sensor.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an air temperature detection structure for an air conditioning indoor unit, including a fresh air channel and an air inlet channel, including a connecting port, wherein the connecting port connects the fresh air channel and the air inlet channel;

[0006] The system includes a sealing plate structure, which comprises a first sealing plate and a second sealing plate, which are intersecting each other and are rotatably disposed at the communication port.

[0007] Includes a temperature sensor, which is disposed between the first sealing plate and the second sealing plate;

[0008] When it is necessary to detect the temperature of the fresh air in the fresh air duct, the rotating sealing plate structure allows the first sealing plate to seal the connection port, thereby placing the temperature sensor inside the fresh air duct; when it is necessary to detect the temperature of the incoming air in the air intake duct, the rotating sealing plate structure allows the second sealing plate to seal the connection port, thereby placing the temperature sensor inside the air intake duct.

[0009] Furthermore, the fresh air duct includes a fresh air volute, and the connecting port is disposed on the fresh air volute.

[0010] Furthermore, the fresh air volute includes a rotating shaft hole, which is disposed on the inner wall of the communication port, and the sealing plate structure includes a rotating shaft, which is rotatably disposed within the rotating shaft hole.

[0011] Furthermore, the intersection line formed by the first sealing plate and the second sealing plate is coaxially arranged with the axis of the rotating shaft.

[0012] Furthermore, the fresh air duct includes a fresh air inlet and a fresh air outlet, and the fresh air volute connects the fresh air inlet and the fresh air outlet, which are located on the rear shell of the indoor unit.

[0013] Furthermore, the sealing plate structure includes a limiting baffle, which is respectively disposed on the first sealing plate and the second sealing plate; when the first sealing plate seals the connection port, the limiting baffle restricts the first sealing plate from continuing to rotate, and when the second sealing plate seals the connection port, the limiting baffle restricts the second sealing plate from continuing to rotate.

[0014] Furthermore, the included angle between the first sealing plate and the second sealing plate is less than or equal to 90 degrees.

[0015] Furthermore, it includes a stepper motor, which has forward and reverse rotation capabilities, and is connected to the sealing plate structure. The stepper motor is used to drive the sealing plate structure to rotate.

[0016] The beneficial effects of this utility model are as follows: 1. By constructing a rotating sealing plate structure within the connecting port, when it is necessary to detect the temperature of the fresh air in the fresh air duct, rotating the sealing plate structure allows the first sealing plate to seal the connecting port, thus placing the temperature sensor within the fresh air duct; when it is necessary to detect the temperature of the incoming air in the intake air duct, rotating the sealing plate structure allows the second sealing plate to seal the connecting port, thus placing the temperature sensor within the intake air duct, thereby achieving the detection of both the fresh air temperature and the intake air temperature. This solution enables the temperature sensor to switch between the fresh air duct and the intake air duct, requiring only one temperature sensor to detect the temperature of both the fresh air in the fresh air duct and the air in the intake air duct. Simultaneously, the first and second sealing plates can work together to seal the connecting port, ensuring the accuracy of temperature detection. 2. By designing the volute housing and integrating the connecting port onto it, the number of internal components is greatly reduced, allowing for more spacious internal layout of the indoor unit. Third, by setting limiting baffles on the first and second sealing plates respectively, when the first sealing plate seals the connection port, the limiting baffle restricts the first sealing plate from continuing to rotate; when the second sealing plate seals the connection port, the limiting baffle restricts the second sealing plate from continuing to rotate, thereby preventing the first and second sealing plates from rotating excessively and failing to seal the connection port. This utility model is particularly applicable to the detection of fresh air temperature in the indoor unit of a fresh air conditioning system. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figures 1 to 8 As shown, the indoor unit's outer casing is formed by fastening together a front casing 2 and a rear casing 1. The outer casing of the indoor unit is cylindrical, and the hollow interior is used to house the corresponding heat exchange equipment. An air outlet 21 is provided on the front casing 2, through which air after heat exchange is blown forward. An air inlet 11 is provided on the rear casing 1, used to introduce indoor air into the indoor unit, thereby achieving heat exchange for cooling or heating within the indoor unit.

[0028] As a fresh air conditioning system, there are also fresh air ducts used to introduce fresh air from the outside, such as... Figure 1 and Figure 8 As shown, the fresh air duct is composed of a fresh air inlet 12, a fresh air volute 4, and a fresh air outlet 13 connected in sequence. The fresh air inlet 12 and the fresh air outlet 13 are located on the rear shell 1. The fresh air inlet 12 is directly connected to the outside atmosphere through a duct, thereby introducing fresh outside air into the room, which is then delivered to the room through the fresh air outlet 13. Both the fresh air inlet 12 and the fresh air outlet 13 are located below the inlet 11. The top of the fresh air volute 4 has a connecting opening 41, which can be a notch created at the top of the fresh air volute 4. The bottom of the connecting opening 41 is connected to the fresh air volute 4, that is, to the fresh air duct. The top of the connecting opening 41 is connected to the inlet 11 through the air intake duct 14. Thus, the upper part of the connecting opening 41 receives the air intake from the inlet 11, and the lower part receives the fresh air from the fresh air inlet 12.

[0029] Figure 6 The illustration shows an embodiment of the sealing plate structure 5, which includes a first sealing plate 51 and a second sealing plate 52. The shapes of the first sealing plate 51 and the second sealing plate 52 are similar to... Figure 5The shape of the connecting port 41 of the fresh air volute 4 is matched to ensure that when the first sealing plate 51 or the second sealing plate 52 rotates into the connecting port 41, the connecting port 41 can be sealed, reducing the airflow between the fresh air channel and the air inlet channel 14 and improving the accuracy of temperature detection. In this embodiment, the first sealing plate 51 and the second sealing plate 52 are rectangular in shape and intersect each other. The intersection line is located on the side of the first sealing plate 51 and the second sealing plate 52. A rotating shaft 53 is provided in the direction of the intersection line, that is, the axis of the rotating shaft 53 is coaxial with the intersection line. The rotating shaft 53 is rotatably disposed in the rotating shaft hole 42 of the fresh air volute 4. Generally, such as Figure 2 and Figure 4 As shown, the included angle between the first sealing plate 51 and the second sealing plate 52 can be less than or equal to 90 degrees, and the temperature sensor 6 is disposed within the included angle region formed by the first sealing plate 51 and the second sealing plate 52. Each of the first sealing plate 51 and the second sealing plate 52 is provided with its own limiting baffle 54. Taking the first sealing plate 51 as an example, the limiting baffle 54 protrudes along the extension direction of the first sealing plate 51 and is disposed on the edge of the first sealing plate 51, such as... Figure 4 As shown, when the first sealing plate 51 rotates to seal the connecting port 41, the limiting baffle 54 contacts the edge of the connecting port 41 and prevents the first sealing plate 51 from continuing to rotate. The rotating shaft 53 is connected to the output shaft of the stepper motor, which can achieve forward and reverse rotation, and drives the sealing plate structure 5 to rotate.

[0030] like Figure 1 and Figure 2 The diagram shows the second sealing plate 52 sealing the connection port 41, allowing the temperature sensor 6 to be positioned within the air inlet channel. At this time, the stepper motor rotates clockwise, driving the sealing plate structure 5 to rotate counter-clockwise. When the limiting baffle 54 of the second sealing plate 52 is tightly engaged with the connection port 41, the sealing plate structure 5 stops rotating, sealing the connection port 41. Both the first sealing plate 51 and the temperature sensor 6 are located within the air inlet channel 14, allowing the temperature sensor 6 to detect the temperature of the incoming air within the air inlet channel 14.

[0031] like Figure 3 and Figure 4The diagram shows the first sealing plate 51 sealing the connection port 41, allowing the temperature sensor 6 to be positioned within the fresh air duct. At this time, the stepper motor reverses, driving the sealing plate structure 5 to rotate clockwise. When the limiting baffle 54 of the first sealing plate 51 is tightly engaged with the connection port 41, the sealing plate structure 5 stops rotating, sealing the connection port 41. The second sealing plate 52 and the temperature sensor 6 are now both located within the fresh air volute 4 of the fresh air duct, allowing the temperature sensor 6 to detect the temperature of the fresh air within the duct.
