Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model. In the description of the present utility model, the meaning of "a plurality" includes two or more unless specifically defined otherwise.

In this application, the term "exemplary" is used to mean "serving as an example, instance, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is presented to enable any person skilled in the art to make and use the utility model. In the following description, details are set forth for purposes of explanation. It will be understood by those of ordinary skill in the art that the present utility model may be practiced without these specific details. In other instances, well-known structures and processes have not been shown in detail to avoid unnecessarily obscuring the description of the utility model. Thus, the present utility model is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles disclosed herein.

It should be noted that, for example, in the volute structure of an air conditioner, the diameter of the air inlet pipe connected to the volute is generally above 75mm, and in order to adapt to the air inlet pipe, the thickness of the air inlet cavity needs to be above 75mm, so that the thickness of the air inlet cavity is very thick, which affects the volute structure and the size of the air conditioner. More specifically, the size of the air conditioner directly influences the installation space of the whole machine, and a user needs a larger suspended ceiling space to meet the installation of the air conditioner, so that the space utilization rate is reduced.

Therefore, the application improves the traditional air inlet structure, the volute and the air conditioner based on the air inlet structure and the volute.

Referring to fig. 1, fig. 1 shows a schematic structure of a volute 500 provided in the present embodiment. The present embodiment is a volute 500, where the volute 500 includes an air inlet structure and a fan blade cavity 300, and the fan blade cavity 300 is communicated with the air inlet structure.

Wherein, the fan blade cavity 300 is provided with fan blades to provide power for the air flow flowing from the air inlet structure to the fan blade cavity 300.

In some embodiments, referring to fig. 2, the air intake structure includes an air intake chamber 100 and an air intake duct 200. One end of the air inlet cavity 100 is communicated with the fan blade cavity 300 through an air outlet, and the other end is communicated with the air inlet duct 200. Wherein the air inlet duct 200 may be used to connect with an air inlet duct.

The air inlet cavity 100 includes a first side wall 110 and a second side wall 120 disposed opposite to each other, and a first air channel is defined between the first side wall 110 and the second side wall 120. That is, the air flow in the air inlet chamber 100 may flow along the first air channel.

The intake stack 200 has a first opening 240 and a second opening 230. The first opening 240 communicates with the first air duct. The second opening 230 is for connecting an air inlet duct. The opening area of the first opening 240 is smaller than the opening area of the second opening 230. That is, the size of the first opening 240 is smaller than that of the air inlet duct.

Currently, the thickness of the intake chamber 100 is limited by the size of the intake duct. On the other hand, in the embodiment of the present application, the second opening 230 is adapted to the air inlet pipe, so as to meet the installation requirement of the air inlet pipe. On the other hand, the size of the first opening 240 may be smaller than that of the air inlet duct, and the size of the first opening 240 is reduced with respect to the conventional art. Thereby enabling a reduction in the spacing between the first and

second sidewalls

110, 120, thereby reducing the thickness dimension of the air intake chamber 100.

In some embodiments of the present application, with continued reference to fig. 2, at least a portion of the air intake duct 200 is configured in a tapered configuration along the first direction a. The first direction a is the flow direction of the air flow in the air inlet duct 200 from the second opening 230 to the first opening 240. It can be appreciated that the tapered structure is beneficial to improving the flow smoothness of the air flow when the air flows in the air inlet duct 200, and is beneficial to avoiding the conditions of high wind pressure and high noise caused by abrupt change of the air flow.

In a more specific embodiment, referring to fig. 2, an air outlet is disposed on the first sidewall 110, and the air outlet is in communication with the first air duct. It will be appreciated that in the construction of the volute 500 or other similar duct component, other components are typically provided in addition to the air outlet. For example, the fan blade, etc. are disposed on a side of the air outlet facing away from the air inlet chamber 100.

The air inlet duct 200 has a third sidewall 210, and the third sidewall 210 is disposed on the same side as the first sidewall 110. For example, in the example structure of fig. 2, the third side wall 210 and the first side wall 110 are both located to the left of the air intake structure.

Wherein at least a portion of the third sidewall 210 is disposed in a tapered configuration along the first direction a. It can be understood that in the structure shown in fig. 2, the third sidewall 210 is protruded to the left, and since other components are also provided to the left of the air outlet, it is possible to avoid increasing the thickness of the scroll case 500 while enlarging the air intake. The thickness of the scroll 500 is understood as the length of the left end to the right end of the scroll 500 in fig. 2.

In some embodiments, referring still to fig. 2, the first side wall 110 and the third side wall 210 meet. The air flow may transition directly from the third side wall 210 to the first side wall 110, which may be advantageous to improve the smooth flow of the air flow. And the tapered structure is disposed at an end of the third sidewall 210 near the first sidewall 110. Because the area of the first opening 240 is small, the airflow is easier to break when flowing into the air inlet cavity 100, so that the tapered structure is arranged close to the first side wall 110, which is also beneficial to improving the stability of the airflow entering the air inlet cavity 100.

In another possible embodiment, the first side wall 110 and the third side wall 210 may not meet. A transition structure may be provided between the first side wall 110 and the third side wall 210 to smoothly transition the airflow from the intake stack 200 into the intake chamber 100.

In some embodiments, referring to fig. 3, a transition boss 130 is disposed on the first sidewall 110 along a direction approaching the second sidewall 120. When the airflow enters the air inlet cavity 100 through the tapered air inlet duct 200, the airflow direction forms an angle with the first side wall 110, and the airflow cannot completely flow along the first side wall 110, so that noise is easily generated. The transition boss 130 can play a buffering role.

With continued reference to fig. 3, the transition boss 130 is provided with a transition curved surface 131 along a direction away from the third sidewall 210, and the transition curved surface 131 is connected with the tapered structure. The transition surface 131 is advantageous for improving the flow smoothness of the air flow.

In some possible examples, the transition curve 131 is a rounded curve to reduce airflow resistance.

In some embodiments, the third sidewall 210 tapers along the rounded curve 211 to form a tapered structure. Is beneficial to reducing the air flow resistance.

In some embodiments of the present application, a support and a filter screen are disposed in the air inlet chamber 100, the filter screen is mounted on the support, and one end of the support is disposed near the transition boss 130, which is beneficial to reducing windage of air flow entering the filter screen and reducing air loss.

In some embodiments of the present application, referring to fig. 4 and 5, the air intake duct 200 has a fourth side wall 220, and the fourth side wall 220 is connected to the second side wall 120. The airflow may transition from the fourth sidewall 220 to the second sidewall 120, which may facilitate reducing airflow resistance.

The junction between the fourth sidewall 220 and the second sidewall 120 is provided with a transition section 400, and the transition section 400 is configured as a diverging structure along a second direction b, where the second direction b is a direction in which the fourth sidewall 220 points to the second sidewall 120. The divergent structure is favorable for increasing the air inlet quantity, reducing the air inlet pressure and further reducing the noise.

In one possible example, the fourth sidewall 220 and the second sidewall 120 are disposed coplanar, which is advantageous for further reducing windage.

In another possible embodiment, the fourth side wall 220 may not be connected to the second side wall 120, and a transition structure may be provided between the second side wall 120 and the fourth side wall 220, so as to smoothly transition the airflow from the air inlet duct 200 into the air inlet cavity 100.

In some embodiments of the present application, please refer to fig. 2 and 4, the length of the transition section 400 in the third direction c gradually increases along the second direction b. The second direction b and the fourth direction d define a first plane, the third direction c is perpendicular to the first plane, and the fourth direction d is a direction in which the first sidewall 110 points to the second sidewall 120. The thickness of the air inlet cavity 100 is not increased, and the air inlet quantity of the air inlet cavity 100 is increased.

In some embodiments, the transition section 400 tapers along the second direction b.

In a more specific embodiment, referring to fig. 4 and 6, the cross section of the transition section 400 in the second plane or the plane parallel to the second plane is an elliptical arc structure 410, the cross section of the air inlet duct 200 in the second plane or the plane parallel to the second plane is an arc structure, and the projection of the arc structure on the elliptical arc structure 410 is tangential to the elliptical arc structure 410; wherein the second plane is perpendicular to the second plane and the second plane is coplanar with the fourth direction d. The thickness of the air inlet chamber 100 is advantageously compressed while ensuring the amount of the air inlet air, so as to reduce the overall thickness.

In some embodiments, the minor half axis of the elliptical arc structure 410 may be smaller than the radius of the circular arc structure.

In some embodiments, the intake stack 200 and the intake chamber 100 are provided as a unitary structure. The structural stability between the air inlet duct 200 and the air inlet cavity 100 is improved.

In some embodiments of the present application, the volute 500 further includes a motor, a motor accommodating chamber is provided on the fan blade, the motor is disposed in the motor accommodating chamber, and a depth of the motor accommodating chamber is not less than a length of the motor. That is, the motor is mounted in the motor housing chamber, and the motor height is not higher than the opening height of the motor housing chamber. So as to reduce the thickness of the vane chamber 300 and thus the thickness of the scroll 500.

It should be noted that, after the motor is installed in the motor accommodation cavity, a gap is provided between the motor and the cavity wall of the motor accommodation cavity so as to avoid interference.

The embodiment of the application also provides an air conditioner, which comprises the volute 500.

In some embodiments, the air conditioner may be an air duct machine.

It should be noted that the volute 500 of the present application may be applied to other fresh air devices.
