DETAILED DESCRIPTION

[0030] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0031] See also Figure 1-Figure 6 The present invention provides a heating structure, which is installed on an air conditioner 1, wherein the heating structure includes a heating unit 2, and the heating unit 2 in a working state can realize radiant heating. The air conditioner can be a wall-mounted air conditioner, and the heating structure is installed on the indoor unit of the wall-mounted air conditioner. The heating unit 2 can be an electric heater. By arranging the electric heater on the existing air conditioner, it is used to radiate heating around the air conditioner, which improves the efficiency of indoor temperature rise compared with the existing air conditioner which can only perform wind heating.

[0032] In addition, it should be noted that the heating mode of the air conditioner 1 and the heating unit 2 can be turned on at the same time to achieve a rapid increase in indoor temperature; or only the heating mode of the air conditioner 1 can be turned on, and the heating unit 2 does not work at this time; or only the heating unit 2 can be turned on, and the air conditioner 1 does not run.

[0033] As an optional implementation of the embodiment of the present invention, the heating structure further includes a heat insulation board 3, and the heat insulation board 3 is arranged between the heating unit 2 and the air conditioner 1. Figure 1 , schematically shows the heat insulation board 3, which is a polyurethane foam board. The setting of the heat insulation board 3 is used to reduce the damage to the air conditioner casing caused by the heat generated by the heating unit 2, thereby improving the safety of the air conditioner casing. The heat insulation board 3 can be installed on the two long blocks 42 by screws.

[0034] As an optional implementation of the embodiment of the present invention, the heating structure is connected to the air conditioner 1 through a rotation drive device, and the rotation drive device can drive the heating structure to rotate. For example: when the air conditioner 1 is heating, the heating structure can be rotated to a suitable position without affecting the hot air output of the air conditioner 1; when the room needs to be cooled, the heating structure can be rotated to a position away from the air outlet of the air conditioner 1, so that the cold air can be output from the air conditioner to the indoor environment.

[0035] As an optional implementation method of the present invention, see Figure 1-Figure 4 , schematically shows a rotation drive device: the rotation drive device includes a support frame 4, a power device 5 and a connection structure 6. The support frame 4 is rotationally connected to the air conditioner 1. The power device 5 is fixed in position. The power device 5 can be an electric cylinder. The housing of the power device 5 can be fixed to the air conditioner 1 by screws. The power device 5 is connected to the support frame 4 through the connection structure 6. When the power device 5 is in motion, the support frame 4 can be driven to rotate through the connection structure 6. The power device 5 is connected to the multi-button switch through a wire, and then the multi-button switch is connected to an external power supply through a wire. By manipulating the multi-button switch, the action of the power device 5 is controlled.

[0036] See also Figure 1 and Figure 3 , schematically shows the specific structure of the support frame 4: the support frame 4 includes a support plate 41 and a long block 42, the two long blocks 42 are rotatably connected to the left and right ends of the air conditioner 1, the support plate 41 connects the two long blocks 42, the support plate 41 can be welded to the two long blocks 42, the heating unit 2 is arranged on the support plate 41, and each long block 42 is connected to a power device 5. When the long block 42 needs to rotate counterclockwise, the multi-button switch is operated to extend the length of the power device 5 until the heating structure rotates to a predetermined position, and the multi-button switch is operated to cut off the power of the power device 5 to facilitate the discharge of cold air / hot air from the air conditioner to the room; when the long block 42 needs to rotate clockwise, the multi-button switch is operated, and after the power device 5 is powered on, the length of the power device 5 shrinks until the heating structure rotates to a predetermined position, and the multi-button switch is operated to cut off the power of the power device 5 to achieve the reset of the power device 5.

[0037] As an optional implementation of the embodiment of the present invention, the left and right ends of the air conditioner 1 are fixed with mounting blocks 43, the interior of the mounting blocks 43 is interference-fitted with a bearing member 44, the inner ring of the bearing member 44 is provided with a fixed shaft 45 interference-fitted with the bearing member 44, and the fixed shaft 45 is connected to the corresponding long block 42. Figure 2 , Figure 4 and Figure 6The mounting block 43 can be mounted on the outer shell of the air conditioner 1 by screws. A groove is provided on the mounting block 43. A bearing member 44 is tightly mounted inside the groove. A fixed shaft 45 is tightly mounted on the inner ring of the bearing member 44. One end of the long block 42 is mounted on the end of the fixed shaft 45 by screws. The long block 42 can rotate relative to the mounting block 43, thereby realizing the rotational connection between the support frame 4 and the air conditioner 1.

[0038] As an optional implementation scheme of the embodiment of the present invention, the connecting structure 6 includes an upper limit portion 61, a lower limit portion 62 and a connecting portion 63. The upper limit portion 61 is connected to the lower limit portion 62 via the connecting portion 63. The connecting portion 63 is connected to the power device 5. The upper limit portion 61 and the lower limit portion 62 are respectively used to cooperate with the upper and lower surfaces of the long strip block 42, and when the long strip block 42 is in a horizontal state, the distance between the upper limit portion 61 and the lower limit portion 62 is greater than the distance between the upper and lower surfaces of the long strip block 42.

[0039] In order to ensure the stability of the movement of the support frame 4, the upper and lower end faces of the long block 42 are provided with guide grooves 421 extending along the length direction of the long block 42. The guide groove 421 arranged at the bottom cooperates with the lower limit portion 62, and the guide groove 421 arranged at the top cooperates with the upper limit portion 61.

[0040] When the support frame 4 rotates counterclockwise, the lower limit portion 62 contacts the lower surface of the long block 42 (the lower surface is the bottom surface of the guide groove 421 arranged below), and the length of the power device 5 is extended, driving the lower limit portion 62 and the upper limit portion 61 to move upward together. Since the lower limit portion 62 contacts the lower surface of the long block 42, the long block 42 is rotated counterclockwise and the lower limit portion 62 moves along the guide groove 421. At this time, the upper limit portion 61 does not contact the bottom surface of the guide groove 421 arranged above, and the maximum counterclockwise rotation angle of the support frame 4 is that the upper limit portion 61 contacts the bottom surface of the guide groove 421 arranged above.

[0041] When the support frame 4 rotates clockwise, the length of the power device 5 shrinks, and the support frame 4 presses against the lower limit portion 62 under the action of gravity, and the long block 42 moves downward with the lower limit portion 62. In addition, it should be noted that if the support frame 4 does not move downward with the lower limit portion 62, the upper limit portion 61 will press against the upper surface of the long block 42 to make the long block 42 rotate clockwise.

[0042] As an optional implementation scheme of an embodiment of the present invention, the connecting portion 63 includes a first connecting plate 631, a second connecting plate 632 and a third connecting plate 633.

The first connecting plate 631 can be arranged horizontally, the second connecting plate 632 can be arranged vertically and the second connecting plate 632 connects the first connecting plate 631 and the third connecting plate 633. The third connecting plate 633 can be arranged horizontally, and the lower limit portion 62 is arranged on the side of the third connecting plate 633 facing the upper end surface of the long strip block 42.

[0043] As an optional implementation of the embodiment of the present invention, the upper limit portion 61 has the same structure as the lower limit portion 62, or the upper limit portion 61 has different structures from the lower limit portion 62. The upper limit portion 61 can be a universal ball, and the connecting end of the upper limit portion 61 is connected to the connecting portion 63. The ball of the upper limit portion 61 can cooperate with the corresponding guide groove 421. The lower limit portion 62 can be a columnar member, and the lower limit portion 62 and the first connecting plate 631 can be connected by screws.

[0044] As an optional implementation method of the present invention, see Figure 5 The heating structure also includes a metal pipe 7, on the outer circumferential side of the metal pipe 7, heat dissipation fins 8 are arranged, and the heat dissipation fins 8 are spaced apart along the circumferential direction of the metal pipe 7, and the heating unit 2 is inserted into the metal pipe 7.
