Fig. 1 to 14 show drawings of an embodiment of the present invention.

A dual-purpose cooling and heating apparatus, as shown in FIGS. 1 to 4, includes a mounting case 10, an air blowing module 20 rotatably coupled to the mounting case 10, and the air blowing module 20 rotatably coupled to the mounting case 10. One side of the mounting shell 10 is provided with a cold air port 11, and the other side is provided with a hot air port 12. The air outlet of the hot air port 12 is provided with a heating piece 13. The blower module 20 rotates relative to the mounting case 10, so that the blower module 20 is provided with an air outlet end 21 opposite to the cold air port 11 or the hot air port 12. When the air outlet end 21 of the air blowing module 20 is opposite to the cold air port 11, cold air or normal temperature air is blown out; when the air outlet end 21 of the air blowing module 20 is opposite to the hot air port 12, the heating element 13 is powered on, so that hot air is blown out.

For ease of installation, the mounting case 10 includes an upper case 106 and a lower case 107. The inner sides of the upper shell 106 and the lower shell 107 are provided with the convex blocks 100. The upper case 106 is disposed opposite to the boss 100 of the lower case 107, and is fixedly coupled by screws.

The blower module 20 is provided with an air inlet end 22, and the air inlet end 22 and the air outlet end 21 form a set angle. Wherein the set angle is 90 ° or 180 °, or other angles. The air outlet end 21 of the rotary air blowing module 20 is opposite to the cold air port 11 or the hot air port 12, different air is blown out, and after the rotary air blowing module rotates for a set angle, the air inlet end 22 can be communicated with the air duct on the mounting shell 10.

In order to make the structure more compact, the air blowing module 20 rotates by a set angle, and the air inlet end 22 is communicated with or opposite to the cold air port 11 when the air outlet end 21 is opposite to the hot air port 12; the air inlet end 22 is communicated with or opposite to the hot air port 12 when the air outlet end 21 is opposite to the cold air port 11. In this case, the rotation angle of the blower module 20 may be set to 90 °.

When the air is communicated, the air inlet end 22 is communicated with the cold air port 11 or the hot air port 12 through a gap between the mounting shell 10 and the blower module 20. In this case, the rotation angle of the blower module 20 may be set as desired.

As shown in fig. 3, the blower module 20 includes a wind scooper 23, a wind drum 24 rotatably coupled to the wind scooper 23, and a power member 25 fixed to one end of the wind scooper 23. Preferably, the power member 25 is a motor and the air drum 24 is a fan. The power member 25 is in transmission connection with the wind drum 24. The air inlet end 22 and the air outlet end 21 are both arranged on the air guide cover 23 and are positioned on different side surfaces. The power member 25 drives the wind drum 24 to generate air flow, and air enters from the air inlet end 22 and is blown out from the air outlet end 21 through the action of the wind drum 24.

Specifically, as shown in fig. 3, 5 and 6, the wind scooper 23 is divided into two parts: the first part is a mount 231 for mounting the air drum 24. The fixing frame 231 is of an arc structure and has an air guiding function. The other part is a mounting plate 232 for mounting the air outlet end 21. The mounting plate 232 is disposed on one side of the fixing frame 231 to form the wind scooper 23, and is divided into two parts for easy processing and installation.

The air outlet end 21 is disposed on the mounting plate 232, and the air inlet end 22 is formed by an open opening on one side of the fixing frame 231 and the mounting plate 232. The cross-sectional area of the air outlet end 21 is smaller than that of the air inlet end 22, so that the air outlet speed is higher. The air inlet end 22 and the air outlet end 21 are disposed on two side surfaces of the air guiding cover 23, so that an included angle between the air inlet end 22 and the air outlet end 21 can be 90, 180 or other angles. The air drum 24 is rotatably connected inside the air guiding cover 23, the power piece 25 is fixed outside the air guiding cover 23, and one end of the air drum 24 extends to the outside of the air guiding cover 23 and is connected with the power piece 25.

Arc rotating blocks 233 are fixed at two ends of the wind scooper 23, and the mounting shell 10 is provided with a rotating round hole 103 matched with the arc rotating blocks 233. The arc rotary block 233 is rotatably connected to the rotary circular hole 103 to switch the air outlet 21 with the hot air outlet 12 and the cold air outlet 11. In order to allow the smooth rotational movement of the blower module 20, the circular arc rotary block 233 is circular and rotatably coupled to the rotary circular hole 103.

Preferably, for the convenience of installation, the mounting case 10 is provided inside with a rotating bracket 14, and the rotating circular hole 103 is provided in the rotating bracket 14. The arc runner 233 is rotatably coupled to the rotating bracket 14.

As shown in fig. 3, 4, 6, and 7, the blower module 20 is provided at one end with a rotary button 26, and the mounting case 10 is provided with a rotary slot 108 rotatably coupled with the rotary button 26. The rotation plate 230 is disposed between the rotation button 26 and the arc rotation block 263 of the blower module 20, and the rotation plate 260 is fixedly coupled to the rotation button 26. The rotary button 26 and the arc rotary block 233 at one end of the air blowing module 20 slide axially, so that the arc rotary block 233 is sleeved in the rotary plate 260, the rotary button 26 rotates to drive the rotary plate 260 to rotate, the rotary plate 260 rotates to drive the air blowing module 20 to rotate through the arc rotary block 233, and finally, the air outlet end 21 is switched with the cold air outlet 11 or the hot air outlet 12.

Preferably, a spring member 27 is provided between the rotating plate 260 and the arc rotary block 233, so that the rotating plate 260 receives an elastic force of the spring member 27. One end of the spring member 27 abuts against the end surface of the arc rotary block 233, and the other end abuts against the rotary plate 260, so that the elastic force of the spring member 27 makes the rotary plate 260 and the arc rotary block 233 not transmit power. When the rotary button 26 is pressed, the spring member 27 is pressed, so that the rotary plate 260 is in transmission connection with the arc rotary block 233, and further, the rotary button 26 is rotated, and the rotary plate 260 drives the air blowing module 20 to rotate, so that the air outlet end 21 of the air blowing module 20 is switched with the cold air outlet 11 or the hot air outlet 12.

The installation of the spring member 27 is not limited as long as the rotary button 26 is pressed and then the rotary button 26 is rotated, thereby rotating the blower module 20. Therefore, a spring member 27 is provided between the rotary knob 26 and the mounting case 10. One end of the spring member 27 is stopped against the mounting case 10, and the other end is stopped against the rotation button 26, so that the elastic force of the spring member 27 makes the rotation plate 260 and the arc rotation block 233 not transmit power. When the rotary button 26 is pressed, the spring member 27 is pressed, so that the rotary plate 260 is in transmission connection with the arc rotary block 233, and further, the rotary button 26 is rotated, and the rotary plate 260 drives the air blowing module 20 to rotate, so that the air outlet end 21 of the air blowing module 20 is switched with the cold air outlet 11 or the hot air outlet 12. The description in this paragraph may be implemented as additional embodiments.

The rotary button 26 is rotatably coupled to the mounting case 10, and the rotary button 26 has an axial movement with the mounting case 10 such that when the rotary button 26 is pressed, the rotary button 26 is rotated to bring the blower module 20 into a rotational movement.

Specifically, as shown in fig. 3 and 7, the rotating plate 260 is provided with a fitting cavity 261 for accommodating the arc rotating block 233. When the spring member 27 is compressed, the rotary plate 260 moves axially along the wind drum 24 so that the arcuate rotary block 233 is inserted into the engagement cavity 261. The fitting cavity 261 is provided with a limiting portion 262 for limiting the axial rotation of the arc rotary block 233, so that when the arc rotary block 233 is located in the fitting cavity 261, the rotary button 26 is rotated to drive the blower module 20 to rotate circumferentially. The rotary knob 26 is pressed by the spring member 27 so that the engagement cavity 261 does not transmit power to the arcuate rotary block 233. When the rotation switching of the blower module 20 is required, the rotation button 26 is pressed to clamp the limit portion 262 of the rotation plate 260 with the arc rotation block 233, so that the rotation button 26 drives the blower module 20 to rotate through the arc rotation block 233. In order to enable the arc rotary block 233 to be accurately inserted into the matching cavity 261, generally, the arc rotary block 233 and the rotary plate 260 are both rotated to a limit position and then inserted.

Specifically, as shown in fig. 6 and 7, a planar limiting portion 262 is disposed in the mounting cavity, and the arc rotating block 233 is provided with a notch 2331. When the arc rotary block 233 is sleeved in the matching cavity 261, the planar limiting portion 262 is opposite to the notch 2331, so that the arc rotary block 233 does not rotate circumferentially relative to the rotary plate 260, and the arc rotary block 233 can be driven to rotate.

As shown in fig. 12, one end of the rotation block 260 extending into the mounting case 10 is provided with an axial stopper 2601, so that the rotation block 260 can only push the blower module 20 under the action of the rotation button 26, and cannot make the rotation block 260 fall out of the rotation groove 108 of the mounting case 10. The rotation plate 260 or the rotation button 26 is provided with a circumferential stopper 263, and the mounting case 10 is provided with a stopper groove 109 matched with the circumferential stopper 263 (the stopper groove 109 is formed between the upper case 106 and the lower case 107). When the air blowing module 20 is switched between the cold air port 11 and the hot air port 12, the circumferential limiting block 263 moves in the limiting groove 109, and the included angle between the two ends of the limiting groove 109 is the switching corner of the cold air port 11 and the hot air port 12. When the circumferential limiting block 263 is located at the position of the limiting groove 109, it is a switching position of the cold air port 11 or the hot air port 12 to prevent the air blowing module 20 from further rotating in the circumferential direction.

As shown in fig. 8, the casing is provided with a micro switch 265, and the wind scooper 23 or the arc rotating block 233 is provided with at least two contact blocks 264 to rotate the blower module 20 by a set angle, and the contact blocks 264 are linked with the micro switch 265 to cut off or energize the micro switch 265.

As shown in fig. 12, the position setting of the microswitch 265 may be variously changed, and another form may be adopted. The inner wall of the mounting shell 10 is provided with a micro switch 265, and the micro switch 265 is arranged at two moving ends of the axial limiting block 2601, so that when the rotating plate 260 rotates, the axial limiting block 2601 touches the micro switch 265. The microswitch 265 can be opened when the blowing module 20 is positioned at the two ends of the limit of the circumferential rotation, so that the power part 25 is electrified at the two ends of the limit, and the wind drum 24 can rotate and be in a normal working state after the switching is finished; similarly, in the middle position of the switching, the microswitch 265 is not turned on, so the power member 25 is not energized and the wind drum 24 is not rotated, to ensure safety.

As shown in fig. 11, the arc runner 233 is provided with a positioning structure 28. The positioning structure 28 includes an elastic member 281 and a positioning groove 282. The elastic member 281 is disposed on the arc rotating block 233, the positioning slot 282 is disposed on the rotating bracket 14 or the positioning block 283, and when the blower module 20 is switched to the position of the cold air inlet 11 or the hot air inlet 12, the elastic member 281 is stopped against the positioning slot 282 to position the blower module 20, thereby preventing the blower module 20 from shaking during operation. The number of the positioning slots 282 is at least two, and the positioning slots are used for positioning at the positions of the cold air inlet 11 or the hot air inlet 12 respectively. The positioning block 283 is fixed to the inner wall of the mounting case 10.

Or the like, or, alternatively,

as shown in fig. 13, the elastic element 281 is fixedly disposed on the arc-shaped rotating block 233, and the positioning slot 282 is disposed on the rotating bracket 14 or the positioning block 283. When the blower module 20 is switched to the position of the cold air inlet 11 or the hot air inlet 12, the elastic member 281 is stopped against the positioning groove 282 to position the blower module 20.

Specifically, the elastic member 281 is composed of a ball and a spring, and when the ball needs to be clamped, the spring stops the ball to be clamped in the positioning groove 282; when the rotary knob 26 rotates the arc rotary block 233 by the rotary plate 260, the ball presses the spring to enable smooth rotation.

As shown in fig. 3 and 4, a first air duct 15 is disposed between the hot air port 12 of the mounting case 10 and the air outlet end 21 of the blower module 20. The heating member 13 is disposed in the first air guide duct 15. The first air duct 15 enables the air outlet end 21 of the blower module 20 to be aligned with the hot air port 12, and does not allow the air emitted from the blower module 20 to leak.

A second air guide duct 16 is arranged between the cold air outlet 11 of the mounting case 10 and the air outlet end 21 of the air blowing module 20.
