This application proposes a window air conditioner.

In the embodiment of the present application, as shown in FIGS. 2 and 4 to 9, the window air conditioner includes a casing 100 and an indoor ambient temperature sensor 410. The casing 100 is provided with an air inlet 131; the electric control box 300 is installed in the casing 100. The indoor ambient temperature sensor 410 is installed on the casing 100 and is located in the direction of the air inlet 131.

In this embodiment, the shape of the casing 100 can be square, cylindrical, etc., and can be selected according to specific usage requirements, and is not specifically limited here. Generally, in order to facilitate manufacturing and molding, the shape of the casing 100 is roughly square. The casing 100 can be specifically composed of a chassis 120 and a front box body 130 and a rear box body 140 provided on the chassis 120. The front box body 130 and the rear box body 140 may be arranged at intervals, in close contact with each other, or integrally arranged. The chassis 120 is installed in the window, the front box 130 is placed indoors to form the indoor side of the window air conditioner, and the rear box 140 is placed outdoors to form the outdoor side of the window air conditioner. An indoor heat exchange duct is formed in the front box 130, an indoor heat exchanger 210 and an indoor fan can be arranged in the indoor heat exchange duct, an outdoor heat exchange duct is formed in the rear box 140, and an outdoor heat exchange duct is arranged in the outdoor heat exchange duct. 220 and outdoor fan.

The casing 100 is also provided with an air inlet 131 and an air outlet, the air inlet end of the indoor heat exchange air duct is connected with the air inlet 131, and the air outlet end of the indoor heat exchange air duct is connected with the air outlet.

The air outlet may be provided on the front side surface, the top surface or the connection between the front side surface and the top surface of the front box 130. Generally, in order to ensure the air inlet area and the blowing effect, the air inlet 131 is arranged on the front side of the front box 130, and the air outlet is arranged at the junction of the front side and the top surface, so that the air flow from the air outlet is blown upward obliquely. Thereby, the air intake volume is increased, and the radiation range of the air flow blowing from the air outlet is wide, and the air supply distance is long.

It can be understood that the indoor environment temperature sensor 410 is used to detect the temperature of the indoor environment. In actual use, the window air conditioner also includes an electric control box 300 and a display box. The electric control box 300 can be installed in the front box 130 or the rear box 140.

In an embodiment, the indoor ambient temperature sensor 410 is electrically connected to the electric control box 300. In another embodiment, the indoor ambient temperature sensor 410 is electrically connected to the circuit board of the display box. Since the indoor air inlet 131 is provided on the front box body, the display box is also provided on the front box body 130. By electrically connecting the indoor ambient temperature sensor 410 to the display box, the indoor ambient temperature sensor 410 is closer to the display box than the electric control box 300, so that the electrical connection line of the indoor ambient temperature sensor 410 is shorter, which simplifies the wiring structure.

The indoor ambient temperature sensor 410 can transmit an electric signal to the electric control box 300 or the display box to serve as a reference temperature when the whole system is running. The indoor ambient temperature sensor 410 can be installed on the casing 100 by means of buckles, screws, straps, magnetic attraction, bonding, etc., as long as the indoor ambient temperature sensor 410 can be installed on the casing 100, here There is no restriction on the specific installation method. The indoor ambient temperature sensor 410 may be specifically installed at the air inlet 131 of the casing 100, such as the edge of the air inlet 131, the middle of the air inlet 131, etc., or in the direction of the air inlet 131, so that the indoor ambient temperature sensor 410 is installed on the machine. The casing 100 is downstream or upstream of the air inlet 131.

Interval.

The window air conditioner of the present application installs the indoor ambient temperature sensor 410 on the cabinet 100, compared to directly installing the indoor ambient temperature sensor 410 on the indoor heat exchanger 210, ensuring that the indoor ambient temperature sensor 410 can detect the indoor environment. Under the premise of temperature, it will not be affected by the temperature of the indoor heat exchanger 210, thereby improving the measurement accuracy of the indoor ambient temperature sensor 410. In addition, by arranging the indoor environment temperature sensor 410 in the air inlet direction of the air inlet 131 of the cabinet 100, the indoor airflow first flows through the indoor environment temperature sensor 410, and then flows into the indoor heat exchanger 210, thereby further improving the indoor environment. The detection accuracy of the temperature sensor 410. And because the airflow blown into by the air inlet 131 is a real-time indoor airflow, the indoor ambient temperature sensor 410 can also realize real-time detection of the indoor ambient temperature, thereby ensuring the stable operation of the system.

In a preferred embodiment, as shown in FIGS. 4 to 6, a supporting rib 150 is provided at the air inlet 131, and the indoor ambient temperature sensor 410 is provided on the supporting rib 150. The air inlet 131 is usually provided with a supporting rib 150 for supporting the filter screen. The indoor ambient temperature sensor 410 may be specifically fixed on the supporting rib 150 by means of straps, magnetic attraction, buckles, bonding, or the like. By arranging the indoor ambient temperature sensor 410 on the supporting ribs 150, the supporting ribs 150 can be fully utilized, and no additional supporting frame is needed to install the indoor ambient temperature sensor 410, thereby simplifying the overall structure. At the same time, arranging the indoor ambient temperature sensor 410 on the support rib 150 in the middle of the air inlet 131 can avoid the blind area of air flow exchange compared to arranging the indoor ambient temperature sensor 410 on the edge of the air inlet 131 or upstream or downstream of the air inlet 131 , Making the measurement of the indoor ambient temperature sensor 410 more accurate.

In another embodiment, please refer to FIGS. 7-9 together. The window air conditioner further includes a first waterproof cover 510, and the first waterproof cover 510 includes a first waterproof cover 510 corresponding to the supporting rib 150. In section 511, the indoor ambient temperature sensor 410 is provided in the first section 511 of the first waterproof jacket 510, and the extending direction of the first section 511 is consistent with the extending direction of the supporting rib 150, and is connected On the supporting rib 150.

In this embodiment, the temperature sensing probe of the indoor ambient temperature sensor 410 is arranged in the first section 511 of the first waterproof jacket 510, that is, arranged at the air inlet 131, so as to be more favorable for detecting the indoor ambient temperature. The first waterproof jacket 510 can be a plastic tube, which plays a role of waterproofing and insulating. The first waterproof jacket 510 can wrap the indoor ambient temperature sensor 410 and its leads, so as to ensure the working reliability of the indoor ambient temperature sensor 410. Specifically, the first waterproof jacket 510 may be a PVC pipe with a thickness of 1 mm. It should be noted that the extension direction of the first section 511 of the first waterproof jacket 510 is consistent with the extension direction of the support rib 150, where the consistency can be completely the same, or there can be a certain angle deviation, for example, the extension direction of the two The difference does not exceed 10 degrees and so on. In this way, the supporting rib 150 can partially or completely shield the first waterproof jacket 510 provided on the supporting rib 150. The supporting ribs 150 may specifically extend horizontally, vertically, obliquely, etc., as long as the filter screen and the indoor ambient temperature sensor 410 can be installed.

By making the extension direction of the portion of the first waterproof cover 510 corresponding to the support rib 150 consistent with the extension direction of the support rib 150, the support rib 150 is fully utilized. On the one hand, the indoor ambient temperature sensor 410 is directly located on the air inlet 131, and more Close to the room, the indoor environment temperature detected is more accurate. On the other hand, the support ribs 150 can shield the indoor environment temperature sensor 410, thereby preventing users from directly observing the indoor environment temperature sensor 410, maintaining the overall appearance consistency, and improving user use Experience.

On the basis of the above-mentioned embodiment, further, as shown in FIGS. 4 and 5, the supporting ribs 150 are arranged to extend transversely, and the first waterproof jacket 510 further includes a second waterproof jacket 510 connected to the first section 511. In section 512, the second section 512 extends from the supporting rib 150, and the housing 100 is further provided with a buckle card 600, and the second section 512 is clamped to the buckle card 600.

In this embodiment, the lead wire of the indoor ambient temperature sensor 410 needs to be electrically connected to the electric control box 300 from the front side of the front box 130 through the end of the indoor heat exchanger 210 (which may be the bottom end, the top end, or the side end); Or, the lead wire of the indoor ambient temperature sensor 410 is directly led from the front side of the front box 130 to the display box. Therefore, the first waterproof jacket 510 needs to be adapted to the length of the lead. That is, the first waterproof jacket 510 extends horizontally and hides behind the supporting ribs 150, and then runs the wire longitudinally to the position where the side of the front wall surface of the front box 130 does not have an air outlet, passes through the buckle card 600, and then from The end of the indoor heat exchanger 210 is connected to the electric control box 300 or directly lead to the display box. Therefore, in addition to the first section 511 corresponding to the supporting rib 150, the first waterproof cover 510 is also provided with a second section 512 connected to the electric control box 300 or the display box. The extension direction of the second section 512 can be determined according to the actual routing, for example, it can be horizontal extension, vertical extension, diagonal extension, bending extension, and so on. The structure of the buckle card 600 can be the same as or different from that of the buckle structure 110. A conventional buckle structure, a wire clamp, or a buckle structure on the housing 100 can be used to restrict the first waterproof jacket 510 from being separated from the front box 130 . The buckle card 600 may specifically be one, two, multiple, and so on. By fixing the first section 511 of the first waterproof jacket 510 on the supporting rib 150 and the second section 512 clamped on the buckle cord 600, the first waterproof jacket 510 has a fixing structure in the length direction, thereby The wiring of the first waterproof jacket 510 on the casing 100 is more tidy, and the connection with the front box 130 is more stable. By extending the supporting ribs 150 in the transverse direction, the space in the length direction of the casing 100 can be fully utilized, and the filter screen and the first waterproof cover 510 can be easily installed.

In one embodiment, referring to FIGS. 4 to 9, the inner wall surface of the supporting rib 150 is provided with a buckle structure 110, and the indoor ambient temperature sensor 410 is clamped to the buckle structure 110.

In this embodiment, the buckle structure 110 provided on the casing 100 may be integrally provided with the casing 100 or separately. In order to maintain connection stability, the buckle structure 110 and the casing 100 may be integrally provided. The buckle structure 110 may be one or more, as long as the indoor ambient temperature sensor 410 can be clamped to the supporting rib 150. By snapping the indoor ambient temperature sensor 410 to the housing 100 through the buckle structure 110, compared to installing the indoor ambient temperature sensor 410 on the refrigerant tube of the heat exchanger through the sensor fixing clip, the setting of the buckle structure 110 is less The molding is more convenient, and there is no need to mold the sensor fixing card separately, which improves the overall efficiency, and the installation space 112 is larger, which makes the installation of the sensor convenient and easier to operate. It is understandable that when the indoor ambient temperature sensor 410 is wrapped in the first waterproof sleeve 510, the first waterproof sleeve 510 should be clamped on the buckle structure 110, so that the indoor ambient temperature sensor 410 is clamped and fixed to the supporting rib. 150 on.

Specifically, referring to Figures 4 to 7, the buckle structure 110 includes two opposite and spaced apart holding arms 111, an installation space 112 is formed between the two holding arms 111, and the indoor ambient temperature sensor 410 is clamped to the installation space 112, and the distance between the two clamping arms 111 gradually changes from the connecting wall of the supporting rib 150 and the buckle structure 110 toward the free end of the buckle structure 110 Decrease the setting.

In this embodiment, by designing the two clamping arms 111 of the clamping structure to have a small entrance and a large internal structure, it is possible to prevent the indoor ambient temperature sensor 410 from popping up after being clamped to the clamping structure, so that the indoor ambient temperature sensor 410 and The connection of the casing 100 is more stable and reliable. The indoor ambient temperature sensor 410 can be inserted into the installation space 112 from the side of the buckle structure 110, and the two clamping arms 111 can also have a certain degree of flexibility. When the indoor ambient temperature sensor 410 needs to be installed, only two The clamping arm 111 is opened, and the indoor ambient temperature sensor 410 is put into the installation space 112, and then the clamping arm 111 clamps the indoor temperature sensor tightly to prevent it from loosening.

An outdoor ambient temperature sensor 420, the outdoor ambient temperature sensor 420 is installed in the electric control box 300 and is at least partially exposed outside.

In this embodiment, the outdoor environment temperature sensor 420 is used to detect the temperature of the outdoor environment. Since the electrical control box 300 requires external wiring, the temperature sensor can be extended to the outdoors through the wiring port of the electrical control box 300, and the temperature of the outdoor environment can be detected. The electric control box 300 can receive the electric signal of the outdoor ambient temperature sensor 420. Through the received temperature values of the outdoor ambient temperature sensor 420 and the indoor ambient temperature sensor 410, the electronic control box 300 can make a comprehensive analysis of the temperature values to obtain data required for system operation, and improve product stability and reliability. By installing the outdoor environment temperature on the electric control box 300, compared to installing the outdoor environment temperature sensor 420 on the refrigerant pipe of the outdoor heat exchanger 220, on the one hand, the outdoor environment temperature sensor 420 is placed far away from the outdoor heat exchanger 220. Therefore, the temperature of the outdoor heat exchanger 220 is prevented from affecting the detection value of the outdoor ambient temperature sensor 420, thereby making the measurement accuracy of the outdoor temperature sensor higher. On the other hand, the outdoor ambient temperature sensor 420 is directly set on the electric control box 300, Make the wiring shorter, thereby avoiding complicated wiring and simplifying the overall wiring structure.

In another embodiment, the window air conditioner further includes an electric control box 300 and an outdoor ambient temperature sensor 420 electrically connected to the electric control box 300, and the outdoor ambient temperature sensor 420 is installed in the cabinet 100 It is located in the direction of the outdoor side of the cabinet 100 in the wind inlet direction. At this time, the electric control box 300 may be arranged in the front box 130.

In this embodiment, the outdoor ambient temperature sensor 420 can be installed on the casing 100 by means of buckles, screws, straps, magnetic attraction, bonding, etc., and it only needs to be able to install the outdoor ambient temperature sensor 420 on the casing 100. Just go ahead, and the specific installation method is not limited here. The rear box 140 of the casing 100 is provided with an outdoor air inlet, and the airflow enters the rear box 140 from the outdoor air inlet to dissipate heat from the outdoor heat exchanger 220.

The outdoor ambient temperature sensor 420 can be specifically installed at the outdoor air inlet of the cabinet 100, such as the edge of the outdoor air inlet, the middle of the outdoor air inlet, etc., or in the direction of the outdoor air inlet, so that the outdoor ambient temperature sensor 420 is installed In the downstream or upstream of the outdoor air outlet of the cabinet 100, such as the rear wall panel, the rear side panel, the left and right side panels of the rear box body, and the like. In order to further reduce the influence of the outdoor heat exchanger 220 on the detection accuracy of the outdoor ambient temperature sensor 420, the outdoor ambient temperature sensor 420 can be arranged at a position farther away from the outdoor heat exchanger 220, or it may have a certain relationship with the outdoor heat exchanger 220. Interval.

By installing the outdoor ambient temperature sensor 420 on the casing 100, compared to installing the outdoor ambient temperature sensor 420 directly on the outdoor heat exchanger 220, it is not necessary to ensure that the outdoor ambient temperature sensor 420 can detect the outdoor ambient temperature. It will be affected by the temperature of the outdoor heat exchanger 220, thereby improving the measurement accuracy of the outdoor ambient temperature sensor 420. In addition, by arranging the outdoor ambient temperature sensor 420 in the direction of the air intake on the outdoor air inlet side of the cabinet 100, since the airflow blown from the outdoor air inlet is a real-time outdoor airflow, the outdoor ambient temperature sensor 420 can also achieve real-time Detect the outdoor ambient temperature to ensure the stable operation of the system
