The air conditioner generally includes a casing, a heat exchanger assembly and a blower assembly, wherein the casing has an air inlet, an air outlet, and an air passage between the air inlet and the air outlet, and the heat exchange component and the air supply assembly are disposed in the air duct. .

The specific structure of the positive and negative ion generator will be mainly described below.

Referring to FIGS. 2 through 4, in an embodiment of the present invention, the positive and negative ion generator 200 includes a generator body 210, a baffle 220, a connecting arm 230, and a probe 240 for generating ions. One end of the connecting arm 230 is fixedly connected to the baffle 220, and the other end is fixedly connected to the generator body 210. The generator, the baffle 220 and the connecting arm 230 enclose a flow channel 201, and the probe 240 is located in the flow channel 201. A first spoiler hole 231 communicating with the flow channel 201 is defined in the connecting arm 230.

Specifically, in the embodiment, the shape of the baffle 220 can be many. In the case of a rectangular plate, the shape of the connecting arm 230 can be many. The long connecting plate is taken as an example. The generator body 210 is arranged in a similar rectangular parallelepiped shape, one surface of which is an outwardly convex curved surface. The flow direction of the airflow in the flow passage 201 is various, and the flow direction of the airflow is parallel to the width direction of the baffle 220, and is parallel to the height direction of the generator body 210, that is, the airflow direction and the convex surface of the generator body 210 The direction is the same. One end of the probe 240 is connected to the end surface of the generator body 210, and the other end extends into the flow path 201. The shape of the first spoiler hole 231 is not particularly limited herein, and may be a circular shape, a polygonal shape, or the like, and a circular shape is taken as an example. When the airflow passes through the flow passage 201, due to the arrangement of the first spoiler hole 231, the airflow enters the flow passage 201 from the first spoiler hole 231, so that the local pressure of the position of the directly blown probe 240 is equivalent to the pressure of the periphery, thereby The airflow of the probe 240 and the other air outlet positions are made to be equalized, and the airflow vortex negative pressure zone M is formed at the top corresponding to the end surface of the generator body 210, thereby avoiding condensation formation in the vortex negative pressure zone M.

When the airflow directly blows the probe 240 and passes through the flow channel 201, the pressure in the region of the probe 240 is increased, and at this time, the airflow is compensated from the spoiler hole into the flow channel 201 to balance the internal pressure, thereby uniformly flowing the airflow to the generator. The periphery of the body 210 avoids forming a vortex negative pressure zone M at the periphery of the generator body 210, thereby avoiding the formation of condensation on the generator body 210, which is advantageous for the user to better use the positive and negative ion generator 200.

In order to better coordinate the pressure inside the air duct, the first spoiler hole 231 is disposed at a centroid of the connecting arm 230 corresponding to the probe 240. In this embodiment, by opening the first spoiler hole 231 corresponding to the probe 240, the external airflow can quickly enter the flow channel 201 and flow to the periphery of the probe 240, so that the air pressure around the probe 240 can be quickly reduced, thereby being more effective.

By opening the first spoiler hole 231 at the centroid of the connecting arm 230, the airflow enters the flow path 201 from a moderate position, so that the pressure in the flow path 201 is more effectively adjusted, which is advantageous for improving the efficiency of the pressure adjustment.

In order to better adjust the direction of the airflow outflow channel 201, the airflow is more uniformly flowed to the periphery of the generator body 210, and the baffle 220 is provided with a second bypass hole communicating with the flow channel 201. The shape of the second spoiler hole 221 is not particularly limited herein, and may be a square, a polygon, or a circle, and a circular shape is taken as an example. The second spoiler hole 221 is disposed corresponding to the probe 240, and the aperture of the second spoiler hole 221 is larger than the maximum radial dimension of the probe 240. By arranging the second spoiler hole 221 corresponding to the probe 240 and setting the aperture to be larger than the radial dimension of the probe 240, the airflow outside the flow path 201 can quickly enter the flow channel 201 and flow to the periphery of the probe 240, thereby being fast The air pressure around the probe 240 is lowered, so that the pressure can be adjusted more effectively and quickly, thereby changing the flow direction of the airflow in the flow path 201, and avoiding the formation of the vortex negative pressure zone M.

Referring to FIG. 5 to FIG. 7 , in order to better adjust the direction of the airflow outflow channel 201 to make the airflow flow more uniformly to the periphery of the generator body 210, the connecting arm 230 is open to communicate with the flow channel 201. The first spoiler 232. The shape and the extending direction of the first spoiler 232 may be paired to extend along the width direction of the connecting arm 230 as an example. By setting the first spoiler 232, the airflow outside the flow channel 201 can quickly enter the flow channel 201 and flow to the periphery of the probe 240, so that the air pressure around the probe 240 can be quickly reduced, thereby enabling more efficient and rapid adjustment. The pressure, in turn, changes the flow direction of the gas flow in the flow path 201, avoiding the formation of the vortex negative pressure zone M.

In order to better adjust the direction of the airflow outflow channel 201, the airflow is more uniformly flowed to the periphery of the generator body 210, and the baffle 220 is provided with a second spoiler slot 222 communicating with the flow channel 201. . The length direction of the second spoiler 222 is the same as the extending direction of the flow channel 201. By setting the second spoiler 222, the airflow outside the flow channel 201 can quickly enter the flow channel 201 and flow to the periphery of the probe 240, so that the air pressure around the probe 240 can be quickly reduced, thereby enabling more efficient and rapid adjustment. The pressure, in turn, changes the flow direction of the gas flow in the flow path 201, avoiding the formation of the vortex negative pressure zone M.

In order to avoid the formation of eddy currents in the flow passage 201, the positive and negative ion generator 200 further includes a partition 250 to which opposite sides of the partition 250 are respectively coupled to the baffle 220 and the generator body 210. The partition 250 separates the air duct into a first air duct and a second air duct. The number of the probes 240 is two, and the two probes 240 are respectively located in the first air passage and the second air passage. The partition 250 is exemplified by a rectangular plate having a length corresponding to the width of the baffle 220 and the height of the generator body 210.
