And, through setting up the ratio scope between width d and the height h of spiral case air outlet 22 to be greater than 0.7 and be less than 1.3, reduced the size difference between width d and the height h of spiral case air outlet 22, effectively increased the angle of sweeping wind of this device, improved the coverage area in body feeling air-out area and the room to effectively improved the heating or refrigeration effect and the user experience of window air conditioner.

The width d direction of the volute air outlet 22 is parallel to the arrangement direction of the two air ducts 23, and after the window type air conditioner is installed, the width d of the volute air outlet 22 is parallel to the horizontal plane. The height h of the volute air outlet 22 is perpendicular to the width d direction of the volute air outlet 22, and after the window type air conditioner is installed, the height h of the volute air outlet 22 is parallel to the vertical direction.

Specifically, the ratio of the width to the height of the volute outlet 22 ranges from greater than 0.7 to less than 1 or from greater than 1 to less than 1.3.

Specifically, the ratio range may be 1.1, 1.2.

As shown in fig. 3 to 5, in some embodiments, at least one partition plate 3 is disposed in the scroll casing 2 near the scroll casing outlet 22, and the partition plate 3 is used for dividing the outlets of the two air ducts 23.

That is to say, set up baffle 3 in the spiral case air outlet 22 to separate the air outlet of two wind channels 23, avoid the air-out of two wind channels 23 to disturb, lead to appearing surging phenomenon, thereby improve the air-out stability of window air conditioner.

The partition plate 3 can extend to the volute air outlet 22, and the end part of the partition plate 3 is flush with the opening of the volute air outlet 22 so as to completely separate the two air channels 23 and realize complete independence of the two air channels 23; or, the end of the partition plate 3 is located inside the volute air outlet 22, so that the gas in the two air channels 23 is converged at a position close to the volute air outlet 22 in the volute 2 and then discharged, and after the gas flow is converged, a farther air supply distance can be obtained, thereby improving user experience.

Specifically, the number of the partition boards 3 is two, the two partition boards 3 are arranged in parallel, and a set distance is provided between the two partition boards 3.

When two partition boards 3 are arranged, the end parts of the two partition boards 3 can be extended to be flush with the end surface of the volute air outlet 22, so that the two air ducts 23 are completely independent. And, set up the distance through setting for between two baffles 3 for have between two wind channels 23 and set for the interval, make spiral case air outlet 22 department form two air outlets along the width direction of indoor side casing 1, in order to improve the wind range of sweeping of window type air conditioner.

And the set distance is less than one third of the width size of the volute air outlet, so that the air sweeping range of the window type air conditioner is improved, and meanwhile, the space corresponding to the area between the indoor space and the two air outlets can be covered by the outlet air of the window type air conditioner.

In some embodiments, each wind channel 23 is provided with a wind wheel 4, and the wind outlet speed can be adjusted by adjusting the rotation speed of the wind wheel 4. That is, when the wind speeds in the two wind channels 23 are different, the wind speeds can be adjusted to be different by adjusting the wind wheels 4. The larger the rotation speed of the wind wheel 4 is, the faster the air outlet speed is.

And, by adopting the double air duct 23, the double air duct 23 works at the same time. Under the condition of achieving the same air output, compared with a single-air-duct 23-window type air conditioner, the rotating speed of each wind wheel 4 in the double-air-duct 23-window type air conditioner is reduced, so that the unilateral load is effectively reduced, the noise of the whole air conditioner is obviously reduced, and the motor can be designed to reduce the air output.

In the indoor side housing 1, the side surface provided with the housing air inlet 11 is perpendicular to the front panel provided with the housing air outlet 12, and the air duct 23 in the volute 2 communicating the housing air inlet 11 and the housing air outlet 12 needs to change the air flow transmission direction once in the air duct 23 in the air flowing process. In this embodiment, the turning of the air duct 23 is provided with a large radian, and the wind wheel 4 is arranged at the turning of the air duct 23 to realize the change of the air flow direction.

In some embodiments, the number of the partition boards 3 is one, the intersection point of a parallel line parallel to the central connecting line of the wind wheels 4 and the partition board 3 at the position where the volute tongue of the volute 2 is closest to the central connecting line of the two wind wheels 4 is the first end of the partition board 3, and the distance a between the first end and the free end of the partition board 3 ranges to be larger than the diameter of the wind wheels 4.

When the number of the partition plates 3 is one, the partition plates 3 are arranged between the two air channels 23 to separate the two air channels 23, so that the phenomenon of surging caused by interference of air outlet of the two air channels 23 is avoided, and the air outlet stability of the window type air conditioner is improved.

That is to say, the minimum distance between the first end of the partition board 3 and the free end thereof needs to be greater than the diameter of the wind wheel 4, so as to ensure that the airflows in the two air channels 23 do not affect each other when converging in the volute 2, avoid the surge phenomenon, and ensure the stability of the airflows generated after the two air channels 23 converge in the volute 2.

In some embodiments, the ratio of the length H to the radius R of each rotor 4 ranges from greater than 2.4 to less than 5.

When the ratio of the length H to the radius R of the wind wheel 4 exceeds 5, the wind wheel 4 is too long, and the air outlet effect is influenced. When the ratio of the length H to the radius R of the wind wheel 4 is less than 2.4, the proportion of the areas with poor work doing at the two axial ends of the wind wheel 4 in the whole wind wheel 4 is too large, so that the system efficiency is reduced.

Specifically, the wind wheel 4 is a cross-flow wind wheel 4.

The wind wheel 4 is set to be the cross flow wind wheel 4, and the cross flow wind wheel 4 has a far air supply distance, so that the air supply distance of the window type air conditioner can be increased, the coverage area of the air outlet of the window type air conditioner is increased, and the heating or refrigerating effect of the window type air conditioner is improved. So that a through-flow duct 23 is formed in the scroll casing 2. And the cross flow wind wheel 4 has the advantage of uniform air outlet, and can improve the uniformity of the air outlet of the window type air conditioner.
