[0035] Figure 1 is a schematic view of a cabinet type air conditioner indoor unit 20 according to an embodiment of the utility model; Figure 2 is Figure 1 a schematic sectional view of the cabinet type air conditioner indoor unit 20 shown in Fig. Figure 3 is Figure 1 a schematic view of the wind baffle of the cabinet type air conditioner indoor unit 20 shown in Fig.

[0036] Referring to Figure 1 and Figure 2 , the embodiment provides a cabinet type air conditioner indoor unit 20, which comprises a shell 21, a supply fan 22 and a wind baffle 23. The front upper side of the shell 21 is provided with an air outlet 21A. The supply fan 22 is arranged on the inner lower side of the shell 21 and has a supply air outlet 22A facing upward. The wind baffle 23 is arranged between the front end of the supply air outlet 22A and the lower end of the air outlet 21A. And the wind baffle 23 has an arc-shaped part 231 gradually bent rearward from bottom to top.

[0037] The existing indoor unit 20 of the cabinet air conditioner either does not have a baffle 23 arranged between the air outlet 22A of the air supply fan 22 and the air outlet 21A inside the cabinet 21, or has a baffle 23 in the form of an integral flat plate. The applicant has found through a large number of researches and experiments that the baffle 23 having an arc-shaped portion 231 gradually bent rearward from bottom to top can guide the airflow blown out from the air outlet 22A of the air supply fan 22 and effectively reduce the noise generated by the indoor unit 20 of the cabinet air conditioner during air supply.

[0038] The air supply fan 22 in the embodiment can generally be a centrifugal fan.

[0039] Figure 4 is Figure 1 is a schematic cross-sectional view of the baffle 23 of the indoor unit 20 of the cabinet air conditioner.

[0040] The applicant has found that when the ratio of the horizontal projection distance to the vertical projection distance of the upper and lower ends of the arc-shaped portion 231 of the baffle 23 is controlled to be greater than or equal to 1:20 and less than or equal to 1:8, or further controlled to be greater than or equal to 1:15 and less than or equal to 1:10, the noise generated by the indoor unit 20 of the cabinet air conditioner during air supply can be further reduced.

[0041] Herein, the horizontal projection of the upper and lower ends of the arc-shaped portion 231 refers to the projection of the upper and lower ends of the arc-shaped portion 231 on the same horizontal plane, and the vertical projection of the upper and lower ends of the arc-shaped portion 231 refers to the projection of the upper and lower ends of the arc-shaped portion 231 on the same vertical plane. Referring to Figure 4 As shown in the figure, the horizontal projection distance of the upper and lower ends of the arc-shaped portion 231 in the embodiment is a, and the vertical projection distance is b.

[0042] In some optional embodiments, the baffle 23 further has a transition portion 232 extending downward from the lower end of the arc-shaped portion 231 from front to rear.

[0043] Referring to Figure 4 As shown in the figure, the arc-shaped portion 231 and the transition portion 232 in the embodiment together form a concave cavity with an opening facing rearward, which causes more airflow blown out from the air outlet 22A of the air supply fan 22 to be pulled forward and guided by the arc-shaped portion 231 of the baffle 23, and further reduces the noise generated by the indoor unit 20 of the cabinet air conditioner during air supply.

[0044] In some optional embodiments, referring to Figure 4 As shown in the figure, the horizontal projection distance of the lower end of the transition portion 232 and the lower end of the arc-shaped portion 231 is less than the horizontal projection distance of the upper end of the arc-shaped portion 231 and the lower end of the arc-shaped portion 231.

[0045] In other words, in the present embodiment, the lower end of the transition portion 232 is located more forwardly than the upper end of the arc-shaped portion 231, or in other words, the upper end of the arc-shaped portion 231 is located more rearwardly than the lower end of the transition portion 232.

[0046] In some alternative embodiments, the wind deflector 23 further has a connecting portion 233 extending vertically downward from the lower end of the transition portion 232.

[0047] In the present embodiment, the connecting portion 233 extends vertically downward from the lower end of the transition portion 232 and extends to a position near the front end of the air supply port 22A of the air supply fan 22, or the lower end of the connecting portion 233 can also be fixed at the front end of the air supply port 22A of the air supply fan 22.

[0048] In some alternative embodiments, the cabinet-type air conditioner indoor unit 20 can further include a heat exchanger 24, as shown in Figure 2 As shown, the heat exchanger 24 is obliquely arranged in the casing 21 and located between the air supply port 22A of the air supply fan 22 and the air outlet 21A on the casing 21, and the lower end of the heat exchanger 24 is near the joint between the connecting portion 233 of the wind deflector 23 and the front end of the air supply port 22A of the air supply fan 22.

[0049] In some alternative embodiments, the wind deflector 23 further has two side plate portions 234 located on the lateral sides of the arc-shaped portion 231. The side plate portions 234 of the present embodiment constitute the side walls of the concave cavity defined by the arc-shaped portion 231 and the transition portion 232, and assist in guiding the airflow.

[0050] Further, in some alternative embodiments, the two side plate portions 234 respectively extend obliquely from back to front to the lateral inner sides of the arc-shaped portion 231.

[0051] In the present embodiment, the two side plate portions 234 respectively extend obliquely from back to front to the lateral inner sides of the arc-shaped portion 231 means that the distance between the two side plate portions 234 gradually decreases from back to front, and the two side plate portions 234 are preferably two straight plates that are left-right symmetrical.

[0052] In some alternative embodiments, the wind deflector 23 further has two fixing portions 235 respectively extending from the rear ends of the two side plate portions 234 to the lateral outer sides. The surfaces of the two fixing portions 235 can form various fixing structures such as screw holes, buckles, etc., to facilitate the fixing of the wind deflector 23 with other parts of the cabinet-type air conditioner indoor unit 20.

[0053] The noise generated by the indoor unit 20 of the cabinet air conditioner is often caused by the superposition of multiple factors. The applicant found through experimental measurement that, without changing other structures of the indoor unit 20 of the cabinet air conditioner, the indoor unit 20 of the cabinet air conditioner combining the above embodiments can reduce the noise by about 0.4 decibels (under the condition of different air volume of the air blower 22) compared with the conventional indoor unit 20 of the cabinet air conditioner provided with the whole flat baffle 23.

[0054] Figure 5 is a schematic view of an air conditioner 10 according to an embodiment of the present application.

[0055] Referring to Figure 5 The present embodiment also provides an air conditioner 10. The air conditioner 10 comprises the indoor unit 20 of the cabinet air conditioner of any of the above embodiments.

[0056] The air conditioner 10 is used for adjusting indoor air, and specifically can comprise one or more functions of adjusting the temperature, humidity, air quality of air, humidifying, dehumidifying, introducing fresh air, etc. of indoor air. It can be understood that, in terms of temperature adjustment, the indoor unit 20 of the cabinet air conditioner of the present embodiment can have other air supply modes not described in addition to the partial air supply modes already listed, and the partial air supply modes listed in the present embodiment are only used to explain specific air supply modes and are not limited to the types of air supply modes.

[0057] The air conditioner 10 can be composed of an evaporator, a condenser, a compressor, a throttling device and other necessary elements to form a vapor compression refrigeration cycle system, so as to output cold air / warm air through the indoor unit 20 of the cabinet air conditioner to achieve refrigeration and heating of the indoor environment.

[0058] At this point, those skilled in the art should recognize that, although the present application has been shown and described in detail in the above embodiments, many other variations or modifications can be determined or deduced directly according to the disclosure of the present application without departing from the spirit and scope of the present application.
