Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.

The drying tunnel assembly provided by the embodiment of the application is detachably arranged on the clothes treatment equipment, the clothes treatment equipment can be a clothes dryer, a washing and drying integrated machine and the like, and for more clearly describing the structures of the drying tunnel assembly and the clothes treatment equipment, the drying tunnel assembly and the clothes treatment equipment are described below with reference to the accompanying drawings.

The fan 20 of the drying tunnel assembly 100 is generally installed above the laundry treating apparatus 200 under the size limitation of the laundry treating apparatus 200, the fan 20 is composed of an impeller, a volute part 101, a collector and other structures, when the fan 20 works, air flow axially enters a blade space from the fan 20, the volute part 101 collects air flowing out from the impeller to flow to an air outlet, and when the motor drives the impeller of the fan 20 to rotate at a high speed, the air between blades on the impeller obtains centrifugal force, and the air is rotated out from an opening between the blades. The gas being spun out hits the volute section 101, increasing the kinetic energy of the gas. Since the volute section 101 is spiral, the flow cross section of the air is gradually increased, kinetic energy is converted into static pressure energy, and then the static pressure energy is converted into kinetic energy in response to the pressurization of the fluid, so that the gas is input into the air channel section 102. When the gas is pressed out, the pressure in the center part of the impeller is reduced, the gas is sucked from the suction inlet of the volute part 101, and the gas is driven by the impeller to rotate along with the impeller on the one hand, and the energy is increased under the action of inertia on the other hand, and leaves the impeller in the radial direction, so that the gas flow is circularly conveyed. However, due to the offset between the volute portion 101 and the air channel portion 102, there is a "climbing" process of the air flow at the air outlet, and the "climbing" process makes the air outlet of the volute portion 101 generate vortex, so that the flow of the fan 20 is reduced, and the full pressure and full pressure efficiency of the fan 20 are reduced in the air flow internal circulation process.

In the present application, the fourth air deflector 304 is provided to break up the vortex at the air outlet, so that the flow velocity of the air flow is increased. Referring to fig. 1-3, fig. 1 is a schematic structural diagram of a drying tunnel assembly according to an embodiment of the present application, fig. 2 is a schematic structural diagram 2 of the drying tunnel assembly shown in fig. 1, and fig. 3 is a partial enlarged view of the drying tunnel assembly 100 shown in fig. 2. The drying tunnel assembly 100 provided by the application comprises a shell 10 and a fan 20, wherein the shell 10 comprises a volute part 101 and a wind channel part 102 which are connected with each other, the volute part 101 comprises a bottom wall 1011 and a volute tongue 1012, and the fan 20 is installed in the volute part 101. The drying tunnel assembly 100 further comprises a guiding structure 30, the guiding structure 30 is at least partially located at one end of the bottom wall 1011 near the air channel portion 102, the guiding structure 30 comprises a first air deflector 301, a second air deflector 302, a third air deflector 303 and a fourth air deflector 304, the first air deflector 301 is close to the volute tongue 1012, the second air deflector 302 and the third air deflector 303 are sequentially arranged at intervals on one side of the first air deflector 301 far away from the volute tongue 1012, and the fourth air deflector 304 is connected to the first air deflector 301 and the second air deflector 302 and is obliquely arranged towards the bottom wall 1011 and the air channel portion 102. Specifically, referring to fig. 4-7 in conjunction with fig. 2, fig. 4 is a flow rate diagram of air flow in a drying tunnel in a state where the guide structure 30 is not provided, fig. 5 is a flow rate diagram of air flow in a drying tunnel in a state where the guide structure 30 is not provided, fig. 6 is a flow rate diagram of air flow in a drying tunnel in a state where the guide structure 30 is provided, fig. 1 is a flow rate diagram of air flow in a drying tunnel in a state where the guide structure 30 is provided, and fig. 7 is a flow rate diagram of air flow in a drying tunnel in a state where the guide structure 30 is provided. Fig. 4 and 6 are airflow velocity diagrams in a top view, and fig. 5 and 7 are airflow velocity diagrams in a cross-sectional view, wherein the darker the color is, the lower the flow velocity is. As shown in the figure, when the guiding structure 30 is not provided, the dark color area is more, and particularly, the dark color area is concentrated at the air outlet, and after the fourth air deflector 304 is set, the fourth air deflector 304 is obliquely arranged towards the bottom wall 1011 and the direction of the air channel part 102, so that the original vortex flow direction is scattered, the turbulence degree of the air is improved, the air channel flow of one side of the first air deflector 301 deviating from the second air deflector 302 and one side of the second air deflector 302 deviating from the first air deflector 301 is obviously improved, and the low flow velocity area is reduced. Experimental data shows that after the guide structure 30 is arranged, the outlet flow of the fan 20 is improved by 8.91%, the full pressure is improved by 5.14%, the full pressure efficiency is improved by 2.37%, the flow speed and the flow rate are improved, the noise generated in the drying tunnel is reduced, the temperature of the air duct is reduced, and the effect of the drying tunnel assembly 100 in the clothes treatment equipment 200 is better.

For example, please refer to fig. 8 in conjunction with fig. 3, fig. 8 is a schematic diagram of the guiding structure shown in fig. 2. The first air deflector 301 includes a first side facing the fan 20, the second air deflector 302 includes a second side facing the fan 20, and the fourth air deflector 304 is partially connected to the first side and the second side. Specifically, the fourth air deflector 304 is partially connected to the first side and the second side at an end of the second side remote from the bottom wall 1011. During the process of passing through the fan 20, the air flow is combined by the impeller and the volute part 101, a vortex is formed at the position of the volute part 101 close to the volute tongue 1012, and according to the position formed by the vortex, the center of the geometric figure corresponding to the fourth air deflector 304 is close to the position of the center of the vortex, so that the vortex is better dispersed. Wherein the first air deflector 301 and the second air deflector 302 are approximately rectangular, the fourth air deflector 304 is partially connected to the first side edge and the second side edge, in some embodiments, the fourth air deflector 304 may not be connected to the first side edge or the second side edge, and the direction towards the bottom wall 1011 and the air channel portion 102 is the lower left, and the fourth air deflector 304 may be disposed above the middle of the first air deflector 301 and the second air deflector 302 and connected to the first air deflector 301 and the second air deflector 302, so as to guide the flow direction of the air current. In some embodiments, the fourth air deflection 304 is an arcuate structure. When the fourth air deflector 304 is in an arc structure, the center of the circle shared by the arc structure is close to the center point of the vortex, so as to better break up the vortex. Compared with a linear structure, when the air deflector is of an arc-shaped structure, the arc-shaped structure can better reduce wind resistance and improve wind flow velocity.
