3 is a schematic view of the three-dimensional structure of FIG. 3 and the exploded structure of FIG. 4, and in conjunction with FIG. 1 and FIG. 2, the air-conditioning air supply device 1 of the embodiment includes three circular air guiding bodies, respectively The toroidal air guiding body 11, the first intermediate toroidal air guiding body 13, and the rear end annular air guiding body 12. Each of the three toroidal air guiding bodies arranged in sequence is a single component and is independently formed. Wherein, the front end circular annular air guiding body 11 is penetrated in the middle, and has two front and rear openings, the front opening is an air outlet 111, the rear opening is an air inlet 112; the first intermediate circular air guiding body 13 is continuous in the middle, and has two front and rear sides. The front opening is an air outlet 131, the rear opening is an air inlet 132; the rear circular air guiding body 12 is continuous in the middle, and has two front and rear openings, the front opening is an air outlet 121, and the rear opening is an air inlet 122, and the opening The air inlet 122 is a non-heat exchange air inlet of the air conditioning air blower 1. Front end annular air guiding body 11, The first intermediate toroidal air guiding body 13 and the rear end circular air guiding body 12 are arranged one behind the other, and a through air passage (not shown) that penetrates all three circular air guiding bodies in the front and the rear is formed in the middle. Moreover, a first circular heat exchange air duct 14 is formed between the front end annular air guiding body 11 and the first intermediate circular air guiding body 13, and the first intermediate circular air guiding body 13 and the rear end are formed. A second circular heat exchange air duct 15 is formed between the annular air guiding bodies 12. When the air conditioning air blowing device 1 is applied to the air conditioner, the internal air duct 4 in the air conditioner passes through the first circular heat exchange air duct 14 and the second circular heat exchange air duct 15 and the air conditioning air blowing device The through air passages in 1 are connected.

Further, an air flow distribution unit 16 extending into the first circular heat exchange air duct 14 and the second circular heat exchange air duct 15 is disposed on the first intermediate toroidal air guiding body 13. Moreover, for ease of processing, the air distribution assembly 16 is preferably integrally formed with the first intermediate toroidal air deflector 13. Of course, it is also possible to form a split body, and then the air distribution unit 16 is mounted and fixed on the first intermediate toroidal air guide body 13.

As shown in FIG. 2, when the air-conditioning air supply device 1 is assembled into the air conditioner, the rear end annular air-guiding body 12 will be fixed to the air-conditioning back plate 3, and the first intermediate circular air-guiding body 13 first The front end circular air guiding body 11 is fixed by screws, and then the front end circular air guiding body 11 to which the first intermediate circular air guiding body 13 is fixed is fixed to the front panel 2 of the air conditioner. After being fixed in position, the air outlet 111 of the front end annular air guiding body 11 serves as an air outlet of the entire air-conditioning air supply device 1, and will be closedly assembled with the mixed air outlet 21 on the front panel 2; and the rear end annular air guiding body The air inlet 122 in the 12 is used as a non-heat exchange air inlet of the entire air-conditioning air supply device 1, and is closed and assembled with the non-heat exchange air inlet 31 on the rear plate 3.

When the air-conditioning air blower 1 of the above configuration is used in the air conditioner, the indoor air enters the air conditioner during the air-conditioning operation, and the air blows toward the heat exchanger 5 to perform heat exchange by the blower. The heat exchange air after the heat exchange is blown from the internal duct 4 to the air-conditioning air blower 1. The heat exchange wind uniformly enters the first circular heat exchange air duct 14 and the second circular heat exchange air duct 15 in the circumferential direction under the distribution of the air distribution unit 16, and then exchanges the air through the heat exchange. The passage enters the through air passage, and is blown out from the air outlet 111 on the front end circular air guide body 11 and the mixed air outlet 21 on the front panel 2 via the through air passage. Due to heat exchange from the wind The larger internal air duct 4 is blown into the annular heat exchange air duct having a smaller area, so that the speed of the heat exchange wind blown from the annular heat exchange air duct becomes larger, so that the surface pressure of the corresponding annular air deflector is reduced. A negative pressure is formed in the through air passage, and the indoor air outside the air conditioner is used as the non-heat exchange air, and under the action of the negative pressure, the non-heat exchange air inlet 31 and the rear end annular air guide body 12 from the rear back plate 3 are The air inlet 122 enters the through air passage, forms a mixed air with the heat exchange air blown by the circular heat exchange air passage, and is smoothly sent to the room together under the diversion of the expanded mixed air flow guiding portion 113.

At a certain fan speed, the air volume test and the temperature detection of the vertical air conditioner, after the air conditioning air supply device 1 is used, the non-heat exchange air introduced is about 1. 1 times the heat exchange air volume, and the obtained mixed air volume is The air-conditioning airflow is increased by about 1. 1 times compared with the air-conditioning air supply of the air-conditioning air supply device 1 in the same condition. Further, if the room temperature is about 26 ° C, the air blown by the air conditioner that does not use the air-conditioning air blower 1 is heat-exchanged air, and the temperature is about 13 ° C; and after the air-conditioning air blower 1 is used, the air conditioner feeds the mixture. The wind is about 19. 5 ° C, the temperature of the mixed wind is more in line with the requirements of human body temperature and temperature comfort. This kind of mixing wind is softer, and it will feel more comfortable when it is blown to the user, which improves the user's comfort experience. Moreover, the air that is not heat-exchanged outside the suction portion is taken into the final air outlet of the air conditioner by the negative pressure generated by the air blowing device 1, which increases the overall air intake of the air conditioner, accelerates the flow of the indoor air, and further improves the flow. The overall uniformity of the indoor air.

In this embodiment, the air-conditioning air blowing device 1 is constructed by combining a plurality of annular air-conducting bodies in the form of a plurality of single-piece components, so that the structure of each of the circular air-conducting bodies can be flexibly controlled according to the air blowing requirement, and is conveniently processed. Each of the circular air guiding bodies having different structures is provided to ensure the uniformity of the air supply and the air blowing speed. Moreover, since each of the toroidal air guiding bodies is a single component, the assembly mode of the entire air conditioning air supply device 1 in the air conditioner can be flexibly selected, thereby improving the application range of the air conditioning air blowing device 1 and the production efficiency of the air conditioning. Further, by providing the air distribution means in the heat exchange air duct, the air distribution means can be used to distribute the heat exchange air entering the air supply means in the circumferential direction, thereby improving the air supply uniformity of the air supply means.

As shown in the radial cross-sectional structural diagram of FIG. 5, in this embodiment, in order to improve the air guiding performance of the air-conditioning air supply device 1, especially the air-conducting ability of the heat-exchanged wind, so that the mixed air is along the annular air guiding body. The surface of the three annular air-conducting bodies is uniformly curved, and each of the circular air-conducting bodies is tapered from the air inlet to the air outlet thereof to form a thick and thin structure, and each The inner diameter of the air inlet of the toroidal air guiding body is larger than the inner diameter of the air outlet. That is, taking the first intermediate toroidal air guiding body 13 as an example, the inner diameter of the air inlet 132 is larger than the diameter of the air outlet 131.

Moreover, the three annular air guiding bodies are coaxially disposed, and the inner diameter of the air outlet of each of the circular air guiding bodies is along the air inlet 122 from the rear end annular air guiding body 12 to the front end annular air guiding body. The direction of the air outlet 111 of 11 is gradually increased. That is, from the front to the rear, the inner diameter of the air outlet 111 of the front end annular air guiding body 11 is larger than the inner diameter of the air outlet 131 of the first intermediate circular air guiding body 13, and the first intermediate circular air guiding body The inner diameter of the air outlet 131 of the body 13 is again larger than the inner diameter of the air outlet 121 of the rear end annular air guide body 12. The inner diameter referred to herein means the inner circumference of the circular opening.

In order to increase the smoothness of the airflow, in particular, the smooth flow of the mixed air, the air-conditioning air supply device 1 may further include a mixed air guiding portion 113 at the front end of the front end annular air guiding body 11, that is, the mixed air guiding portion 113 is located between the front end annular air guiding body 11 and the air conditioning front panel 2. Preferably, the front end annular air guiding body 11 and the mixed air guiding portion 113 are integrally formed to form a seamless joint to ensure the continuity of the surface and facilitate the flow of the air.

The front end annular air guiding body 11 is a main component for guiding the heat exchange wind, and its surface is a curved surface to guide the heat exchange wind along the front end circular air guiding body 11 into the through air passage. The mixed air guiding portion 113 serves as a main component for guiding the mixed air obtained by mixing the heat exchanged air and the non-heat exchanged air, and adopts a structure in which the surface is a flat surface or a micro-arc surface (a curved surface having a large radius of curvature). Preferred is a plane. Further, the mixed air guiding portion 113 is gradually expanded outward from the rear to the front to form a bell mouth shape, and the mixed air can be smoothly drained from the through air passage to the front opening 1131, and further from the mixed air outlet on the air conditioning front panel 2. Blow out in the 21st.

In addition, in order to facilitate the assembly of the air-conditioning air supply device 1 on the air conditioner, a mounting portion 124 is further provided at the rear end of the rear end annular air guiding body 12, and the mounting portion 124 is a flanged structure, and preferably and a rear end. The toroidal air guiding body 12 is integrally formed. Wherein, the rear end annular air guiding body 12 is used as a main component for guiding heat exchanged wind and non-heat exchanged wind, and adopts a surface curved surface structure to guide heat exchange wind and non-heat exchange. The air change enters the through air duct along the inner and outer air guiding surfaces. The mounting portion 124 preferably adopts an outer flange structure with a flat surface to facilitate installation and fixation with the back panel 3 of the air conditioner.

The air-conditioning air blower 1 that can send the mixed air of the air-conditioning heat exchanger heat exchange air and the external non-heat exchange air is essential for reducing the wind resistance, reducing the pressure loss, and reducing the noise. Further, the air volume of the external non-heat exchange air sucked by the air-conditioning air supply device and the temperature of the mixed air outlet air are affected, and the structure of the heat exchange air duct mainly depends on two adjacent circular rings forming the air passage. The relative positional relationship of the air guiding body and the structure of the air guiding body itself. Therefore, the heat exchange air passages of the air-conditioning air supply device 1 of this embodiment are specifically configured as shown in Fig. 6.

Figure 6 is a simplified block diagram of Figure 5 with the air distribution assembly 16 removed. Any of the heat exchange air ducts is disposed under the following conditions: a first circular heat exchange air duct 14 formed between the front end annular air guiding body 11 and the first intermediate circular air guiding body 13 For example, the air passage has an air outlet end 142 that is close to the through air duct of the air conditioner air blower 1 and an air inlet end 141 that is away from the through air duct and located on the opposite side of the air outlet end 142, and the first circular heat exchange The wind tunnel 14 tapers from its air inlet end 141 to the air outlet end 142.

Specifically, the front end annular air guiding body 11 and the first intermediate circular air guiding body 13 are disposed such that the surfaces of the two air guiding bodies in the first circular heat exchange air duct 14 are located. The diameter of the tangent circle is tapered from the air inlet end 141 to the air outlet end 142 at a reduction ratio of 5-25%, and is preferably tapered at a non-equal rate of reduction. A more preferable reduction ratio is 10-20%. For example, as shown in FIG. 6, there are three tangent circles in the first toroidal heat exchange air duct 14, which are 143, 144, and 145, respectively. Wherein, the tangent circle 143 is a tangent circle at the inlet end 141, defined as a tangent circle at the inlet end, and has a diameter D1; a tangent circle 145 is an intermediate tangent circle having a diameter D2; a tangent circle 144 The tangent circle at the outlet end 142 is defined as a tangent circle at the outlet end and has a diameter of D3. The following relationship is satisfied between the diameters: D3/D2 = [ l - (5-25%) ] , D2 / D1 = [ 1- (5 - 25%) ]. Preferably, D3/D2=[1-(10-20%)], D2/D1=[1-(10-20%)], and D3/D2≠D2/D1. Further, in this embodiment, the relationship between the diameter D1 of the tangential circle 143 of the inlet end and the diameter D3 of the tangential circle 144 of the outlet end is also satisfied: D3/Dl=60-70 More preferably, D3/ Dl=65 Similarly, there are three tangent circles in the second toroidal heat exchange air duct 15, which are respectively tangent to the air inlet end of the air inlet end 151 and tangent to the air outlet end of the air outlet end 152. 154 and an intermediate tangent circle 155 in the middle, the diameter relationship of the three tangent circles also satisfy the above conditions.

Moreover, in this embodiment, the diameter of the air inlet end tangent circle 153 of the second toroidal heat exchange air duct 15 is larger than the tangent circle 143 of the air inlet end of the first toroidal heat exchange air duct 14 The diameter of the tangential circle 154 of the outlet end of the second toroidal heat exchange air duct 15 is larger than the diameter of the tangential circle 144 of the outlet end of the first toroidal heat exchange air duct 14. Therefore, the volume of each of the heat exchange air ducts is gradually changed from the non-heat exchanged air inlet 122 of the rear end annular air guide body 12 to the mixed air outlet 111 of the front end circular air guide body 11 .

After the annular heat exchange air ducts are arranged according to the above structure, the direction of the heat exchange wind can be changed, so that both the heat exchange air and the non-heat exchange air are blown along the surface of the annular air guide body, thereby effectively avoiding the wind passing through the two parts of the wind. The surface of the non-annular air deflector in the channel meets at the surface to reduce the wind speed and cause condensation.

Referring again to the schematic rear view of FIG. 7, the airflow distribution assembly 16 of this embodiment is implemented using a plurality of air distribution plates. The air distribution assembly 16 of this embodiment includes a total of four pairs, eight air distribution plates, respectively, a main air distribution plate 161 and 162, first auxiliary air distribution plates 163 and 164, and second auxiliary air distribution plates 165 and 166. The third auxiliary air distribution plates 167 and 168. All air distribution plates are curved distribution plates with the same bending direction, and the surface of each air distribution plate is curved curved surface, which can effectively guide the wind direction and reduce the pressure loss and noise of the airflow during the shunting process, achieving low High-speed air supply under the premise of noise. The four pairs of air distribution plates are sequentially in the order of the primary air distribution plates 161 and 162, the first auxiliary air distribution plates 163 and 164, the second auxiliary air distribution plates 165 and 166, and the third auxiliary air distribution plates 167 and 168. The left and right sides are symmetrically distributed in the circumferential direction of the first toroidal heat exchange air duct 14 and the second toroidal heat exchange air duct 15. That is, in the direction of the bottom-up heat exchange air supply, the left side of the air-conditioning air supply device 1 (the left and right sides in the rear view direction) is provided with the main air distribution plate 161 from the bottom, and the first The auxiliary air distribution plate 163, the second auxiliary air distribution plate 165 and the third auxiliary air distribution plate 167, and the main air distribution plate 162, the first auxiliary air distribution plate 164, The second auxiliary air distribution plate 166 and the third auxiliary air distribution plate 168 are disposed on the right side of the air-conditioning air blower 1 in a bilaterally symmetrical manner. Moreover, the bending direction of each air distribution plate is opposite to the heat exchange air blowing direction. That is, the heat exchange air blowing direction is from bottom to top, and the bending reverse direction of each air distribution plate will be the reverse air blowing direction, that is, the counterclockwise bending as shown in FIG.

The heat exchange air from the heat exchanger can be divided into left, middle, and right by the main air distribution plates 161 and 162 by providing the air distribution assembly 16 formed by a plurality of curved air distribution plates radially distributed symmetrically in the heat exchange air duct. In the three parts, the heat exchange winds on the left and right sides can be diverted again by the auxiliary air distribution plates, and finally the uniformity of the air and air in the circumferential direction of the heat exchange air duct of the air conditioning air supply device 1 is realized. The air supply uniformity of the air-conditioning air supply device 1 is improved.

Of course, the air distribution unit 16 can be implemented in addition to a plurality of curved air distribution plates, and other configurations can be employed as long as it is possible to uniformly distribute the heat exchange air from the heat exchanger 5 in the circumferential direction.

For each air distribution plate, its shape, area, and location in the heat exchange air duct are critical factors influencing the uniformity of the air supply. In this embodiment, the shape and area of the paired air distribution plates are the same. However, for a plurality of air distribution plates on one side, the area of the main air distribution plate 161 or 162 is larger than the area of the first auxiliary air distribution plate 163 or 164 from the bottom to the top, the first auxiliary air distribution plate 163 or The area of 164 is greater than the area of the second auxiliary air distribution plate 165 or 166, which in turn is larger than the area of the third auxiliary air distribution plate 167 or 168.
