As shown in fig. 1a, 1b and 1c, the present invention provides an indoor air treatment device, which comprises an air suction unit 13, wherein the air suction unit 13 is provided with an air suction inlet 1311 for sucking air, a guide cover 12 is covered on the air suction inlet 1311, and a plurality of guide holes 1221 are formed in the guide cover 12; an airflow channel 15 is formed between the air guide sleeve 12 and the air suction unit 13; when the air suction port 1311 sucks air, a part of the air enters the air suction port 1311 through the diversion hole 1221, and another part of the air enters the air suction port 1311 through the airflow passage 15.
In the indoor air treatment device, as the air suction inlet 1311 of the air suction unit 13 is covered with the air guide cover 12, the air guide cover 12 is provided with a plurality of air guide holes 1221, and an air flow channel 15 is formed between the air guide cover 12 and the air suction unit 13; when the air suction port 1311 sucks air, a part of the air enters the air suction port 1311 through the diversion hole 1221, and the other part of the air enters the air suction port 1311 through the airflow channel 15, so that the airflow flows to different parts of the air suction port 1311 from two paths respectively. Thus, the air flow uniformly flows into the suction unit 13 of the indoor air treatment device 1 from the suction inlet 1311, so that the indoor air flow is uniform, and the use comfort of users is improved. In addition, since the air guide sleeve 12 covers the air suction inlet 1311, a user cannot directly observe the internal structure of the indoor air treatment device 1 from the air suction inlet 1311, thereby improving the aesthetic property of the product; but also can reduce noise.
In the indoor air treatment device of the present invention, the air guide cover 12 covered on the air suction inlet 1311 of the air suction unit 13 enables air flow to enter the air suction inlet 1311 from the air guide hole 1221 and the air flow channel 15, as shown in fig. 2a, 2b, 2c and 2d, the air guide cover 12 includes a bottom plate 121 and a first air guide shroud 122, the first air guide shroud 122 and the bottom plate 121 enclose an air flow cavity 14, the opening of the air flow cavity 14 faces the air suction inlet 1311, and the air guide hole 1221 is disposed on the first air guide shroud 122 and is communicated with the air flow cavity 14; the air suction unit 13 comprises a second flow guiding baffle 1312, the second flow guiding baffle 1312 surrounds an air suction inlet 1311, and the air flow channel 15 is positioned between the first flow guiding baffle 122 and the second flow guiding baffle 1312; when the suction port 1311 sucks air, a part of the air flow directly enters the suction port 1311 from the air flow passage 15, and the part of the air flow flows into the suction unit 13 from the edge portion near the suction port 1311; another part of the air flows from the air flow hole 1221 into the air flow cavity 14 and flows from the air flow cavity 14 into the air suction port 1311 again, as shown in fig. 1a, the upper edge of the first air flow guiding shroud 122 gathers towards a position close to the center of the air suction port 1311, so that the air flow flowing from the air flow cavity 14 into the air suction port 1311 is distributed at a position close to the center of the air suction port 1311; therefore, the air flow directly flowing into the air suction inlet 1311 from the air flow channel 15 is distributed at a position close to the edge of the air suction inlet 1311, and the air flow flowing into the air suction inlet 1311 through the air flow guide hole 1221 and the air flow containing cavity 14 is distributed at a position close to the center of the air suction inlet 1311, so that the air flow in the air suction inlet 1311 is uniformly distributed, the air flow pressure at the air suction inlet 1311 is uniform, more air quantity is conveniently sucked, and noise generated by the air flow can be reduced.
As described above, in an indoor air treatment apparatus according to the present invention, the first baffle 122 encloses the airflow accommodating chamber 14 on the bottom plate 121, and the second baffle 1312 is disposed around the air suction inlet 1311, and the opening of the airflow accommodating chamber 14 faces the air suction inlet 1311, so that the airflow can smoothly flow into the air suction inlet 1311 under the guidance of the first baffle 122 and the second baffle 1312. As shown in fig. 2d, the cross section of the first baffle 122 cut along the center line 1311a of the inlet 1311 is a pair of first arc structures 1222 spaced on both sides of the center line 1311a of the inlet 1311, and the surface of the first baffle 122 facing the side of the second baffle 1312 protrudes toward the bottom plate 121; the second baffle 1312, which is cut along the center line 1311a of the inlet 1311, has a pair of second arc-shaped structures 1312a spaced apart on both sides of the center line 1311a of the inlet 1311, and the surface of the second baffle 1312 facing the side of the first baffle 122 is recessed toward the bottom plate 121, so that the cross section of the air flow channel 15 between the first arc-shaped structures 1222 and the second arc-shaped structures 1312a smoothly transitions, facilitating smooth flow from the air flow channel 15 into the inlet 1311.
In order to enable the airflow to enter the airflow cavity 14 uniformly, as shown in fig. 2b and 2c, a plurality of flow guiding holes 1221 are distributed on the side wall of the first flow guiding coaming 122, and the flow guiding holes 1221 may have a hole-shaped structure with smooth edges, such as a circular or oval shape, so that the airflow flows from each flow guiding hole 1221 into the airflow cavity 14 respectively, and the flow of the airflow is relatively uniform.
In an indoor air treatment apparatus of the present invention, the air flow path 15 may be provided in a structure having equal width throughout, and as a preferred embodiment, the first arc-shaped structure 1222 and the second arc-shaped structure 1312a may be provided concentrically, so that the air flow path 15 has equal width throughout and smoothly transits. As shown in fig. 2d, the end of the first arc structure 1222 near the center line 1311a of the air inlet 1311 is an end a, the end of the second arc structure 1312a near the center line 1311a of the air inlet 1311 is an end B, and as a preferred embodiment, the distance between the end a and the center line 1311a of the air inlet 1311 is greater than the distance between the end B and the center line 1311a of the air inlet 1311, so that the opening of the airflow cavity 14 surrounded by the first baffle 122 gathers towards the center line 1311a of the air inlet 1311, and the airflow flowing from the airflow cavity 14 to the air inlet 1311 is distributed towards the center of the air inlet 1311. In order to allow the airflow from the airflow channel 15 to the suction port 1311 to be partially distributed towards the center of the suction port 1311, as shown in fig. 2d, the angle between a tangent 1222a of the first arc-shaped structure 1222 near one end (i.e. the a end) of the center line 1311a of the suction port 1311 and the center line 1311a of the suction port 1311 is 50 ° -70 °, preferably 60 °; thus, under the guidance of the end of the first arc 1222A, a portion of the airflow in the airflow channel 15 is distributed toward the center of the inlet 1311 near the tangential line 1222A of the end a, so as to avoid the airflow from the airflow channel 15 to the inlet 1311 from being excessively concentrated at the edge of the inlet 1311. As shown in fig. 2e, the air flow is calculated from simulation and calculated to enter the air suction inlet 1311 from the air flow channel, and the arrows in the figure represent the air flow, and as the air suction inlet 1311 is covered with the air guide cover 12, the air flow is uniformly distributed in each area of the air suction inlet 1311, the air suction inlet 1311 can suck more air flow, and the air flow is not excessively gathered at the edge of the air suction inlet 1311, and is free from turbulence, and the air flow can smoothly flow into the air suction inlet, so that the noise is smaller, and the introduced air flow is uniform.
In an indoor air treatment apparatus of the present invention, the air flow channel 15 may be further configured to have a width gradually changed, as a preferred embodiment, as shown in fig. 2d, a side of the air flow channel 15 near a center line 1311a of the air suction inlet 1311 is a first air flow port 151, and a side of the air flow channel 15 far from the center line 1311a of the air suction inlet 1311 is a second air flow port 152; the width of the airflow channel 15 increases from the first airflow port 151 to the second airflow port 152, the second airflow port 152 is further away from the exhaust fan 132a in the air suction unit 13, and the wider arrangement of the second airflow port 152 can enable the airflow to be sucked into the airflow channel 15 more easily, so that dust in the airflow channel can be cleaned conveniently. As shown in the foregoing, the airflow channel 15 may have an equal width, or the airflow channel 15 may be configured to gradually increase from the first airflow port 151 to the second airflow port 152, and generally, the ratio of the width of the first airflow port 151 to the width of the second airflow port 152 is greater than or equal to 0.5 and less than 1, so that the airflow flowing into the airflow channel is smooth, and the appearance of the airflow channel is good in aesthetic appearance.
In order to enable the airflow to be uniformly distributed at each position of the air suction inlet 1311, as shown in fig. 2a and 2b, the air suction inlet 1311 is provided with an air guide grid 1313, and the air guide grid 1313 can enable the airflow to be dispersed and be more uniformly distributed at each position of the air suction inlet 1311, so that the air suction inlet 1311 is facilitated to suck more air quantity. On the other hand, the air guide grid 1313 can prevent the user from carelessly inserting fingers into the air suction port 1311 to be cut by the air discharge fan 132a in the air discharge air chamber 16, and the air guide grid 1313 can also prevent foreign matters from entering the air discharge air chamber 16 from the air suction port 1311 and colliding with the running air discharge fan 132a to affect the normal running of the air discharge fan 132 a.
Referring to fig. 2a, 2b, 2c and 2d, the first baffle 122 and the second baffle 1312 each enclose an annular structure, the gap between the first baffle 122 and the second baffle 1312 forms the air flow channel 15, if the air flow channel 15 is directly directed to the user, the air flow direction of the air flow channel 15 will cause the user to feel a distinct feeling of blowing, which may cause discomfort to the user, and in order to avoid this, as shown in fig. 1a, 1b and 2c, a connecting plate 1211 is connected to one side edge of the bottom plate 121, and the connecting plate 1211 covers part of the second air flow opening 152. The side of the second airflow opening 152 that is covered is directed in the direction in which the user is constantly moving, so that the user does not feel a noticeable feeling of wind. In addition, compared with the case that the second airflow port 152 is not covered at all, the second airflow port 152 is covered partially, so that the airflow flowing to the air suction port 1311 is smooth, the impedance is low, the noise is low, the air return quantity is ensured, the user can not directly observe the airflow channel 15, and the attractiveness of the indoor air treatment device 1 is ensured.
