[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0037] like Figures 1 to 10 As shown, the present invention provides an electric heating component 2, which is arranged in a housing 100 of an electrical device. The electric heating component 2 includes: a rotating shaft 8, which is rotatably arranged on the housing 100; an electric heating body 6, which includes a heating position located in the housing 100 to heat the intake air flow and a avoidance position located outside the housing 100 to avoid the intake air flow. The electric heating body 6 is fixedly connected to the rotating shaft 8 to rotate with the rotating shaft 8 to switch between the heating position and the avoidance position; wherein, an avoidance groove 7 is provided on the housing 100, and the avoidance groove 7 is located on the movement path of the electric heating body 6 to avoid the movement of the electric heating body 6.
[0038] In this way, the electric heating component 2 of the present invention is installed on an air conditioner with heating requirements. When the air conditioner is heating, the electric heating body 6 can be moved to the heating position, that is, the air outlet side of the fan, to realize the function of heating the incoming air flow. When the air conditioner is cooling, the electric heating body 6 can be moved to the avoidance position to keep the air duct of the air conditioner smooth, reduce the air volume loss during cooling, improve the cooling efficiency, and avoid the occurrence of condensation water on the electric heating component in the cooling mode. It solves the problem in the prior art that the electric heating device of the air conditioner is prone to condensation water when the air conditioner is in the cooling mode, thereby causing electric heating failure. When repairing and replacing the electric heating component, there is no need to remove the entire panel of the air conditioner, which improves the efficiency of repairing and replacing the electric heating component, and can cut off the power to the electric heating component when it fails to avoid burning other components, thereby protecting other components of the air conditioner.
[0039] like Figures 1 to 8As shown, the electric heating assembly 2 also includes: an isolation plate 5, the isolation plate 5 includes a non-isolation position for avoiding the electric heating body 6 located in the heating position and an isolation position for isolating the electric heating body 6 located in the avoidance position; an isolation plate driving component 14, the isolation plate driving component 14 is driven and connected to the isolation plate 5 to drive the isolation plate 5 to move between the non-isolation position and the isolation position.
[0040] In this way, when the isolation plate 5 is in the isolation position, the electric heating body 6 can be isolated from the interior of the air conditioner, preventing the electric heating component 2 from burning the entire air conditioner when a failure occurs.
[0041] like Figures 1 to 8 As shown, the first end of the isolation plate 5 is hinged to the side of the electric heating body 6 away from the rotating shaft 8; the isolation plate driving component 14 includes a telescopic connecting rod 4, the first end of the telescopic connecting rod 4 is hinged to the second end of the isolation plate 5, and the second end of the telescopic connecting rod 4 is movably arranged on the electric heating body 6 along a predetermined trajectory.
[0042] like Figures 1 to 8 As shown, the electric heating body 6 is provided with a slide groove 11 extending along a predetermined track; the isolation plate driving component 14 includes a pulley 15, which is movably installed in the slide groove 11 and hinged to the second end of the telescopic connecting rod 4.
[0043] The isolation plate driving component 14 of the present invention includes a locking component, which includes a locking position for locking the pulley in the slide groove 11 and an unlocking position for avoiding the movement of the pulley in the slide groove 11. The locking component is movably arranged on the pulley to switch between the locking position and the unlocking position.
[0044] like Figure 9 and Figure 10 As shown, the locking component includes a locking pin 17, and a mounting cavity for accommodating the locking pin 17 is provided on the pulley 15. The locking pin 17 can be movably set on the pulley to extend out of the mounting cavity to stop the movement of the pulley or retract into the mounting cavity to avoid the movement of the pulley; a pin groove 16 for inserting one end of the locking pin 17 is provided on the groove wall surface of the slide groove 11. There are two pin grooves 16, and the two pin grooves 16 are respectively arranged to correspond to the positions of the pulley 15 when the electric heating body 6 is in the heating position and the avoidance position, so that when the electric heating body 6 moves to the heating position or the avoidance position, one end of the locking pin on the pulley 15 can be inserted into the corresponding pin groove 16 to fix the position of the pulley 15.
[0045] Specifically, one of the extending and retracting actions of the locking pin 17 is driven by hydraulic pressure, and the other is driven by an elastic return member provided in the installation cavity.
[0046] like Figures 1 to 8As shown, the electric heating component 2 also includes a protective shell 12, which is located outside the outer shell 100 and is detachably mounted on the outer shell 100. The protective shell 12 includes an avoidance cavity 10 connected to the avoidance groove 7 for accommodating the electric heating body 6, and the avoidance position is located in the avoidance cavity 10.
[0047] like Figures 1 to 8 As shown, the protective shell 12 includes a main shell 121 and a plurality of connecting plates 122 arranged in sequence around the circumference of the main shell 121 and connected to the main shell 121. Each connecting plate 122 is connected to the outer shell 100 through a fastener.
[0048] like Figures 1 to 8 As shown, the electric heating assembly 2 includes a motor 9 , which is mounted on the housing 100 and is drivingly connected to the rotating shaft 8 to drive the rotating shaft 8 to rotate.
[0049] like Figures 1 to 8 As shown, the present invention provides an air conditioner, comprising a housing 100 and a fan 1 and an evaporator 3 arranged in the housing 100. The air conditioner also includes the above-mentioned electric heating component, which is arranged on the housing 100; wherein, when the electric heating component is in the heating position, the electric heating component is located between the fan 1 and the evaporator 3; when the electric heating component is in the avoidance position, the electric heating component is located between the housing 100.
[0050] like Figure 11 As shown, the present invention also provides an electric heating component control method, which is applicable to the above-mentioned electric heating component 2, and the electric heating component 2 is installed in the air conditioner. The electric heating component control method includes: when the air conditioner switches from a heating mode to a cooling mode, first, cutting off the connection between the power supply of the electric heating body 6 and the power supply of the air conditioner, then controlling the electric heating body 6 to move from the heating position to the avoidance position, and finally connecting the connection between the power supply of the electric heating body 6 and the power supply of the air conditioner; when the air conditioner switches from a cooling mode to a heating mode, first, cutting off the connection between the power supply of the electric heating body 6 and the power supply of the air conditioner, then controlling the electric heating body 6 to move from the avoidance position to the heating position, and finally connecting the connection between the power supply of the electric heating body 6 and the power supply of the air conditioner; when a fault occurs in the electric heating body 6 and the electric heating body 6 is in the heating position, first, a fault alarm is issued, then cutting off the connection between the power supply of the electric heating body 6 and the power supply of the air conditioner, and finally controlling the electric heating body 6 to move from the heating position to the avoidance position.
[0051] When the air conditioner switches from heating mode to cooling mode, the connection between the power supply of the electric heating body 6 and the power supply of the air conditioner is first disconnected, and the motor 9 driven by the rotating shaft 8 is started to control the electric heating body 6 to move from the heating position to the avoidance position; the locking component is controlled to move to the unlocked position so that the pulley can move in the slide rail. Through the movement of the pulley and the extension and contraction of the telescopic connecting rod, the isolation plate 5 moves to the isolation position along with the electric heating body 6; when the electric heating body 6 reaches the avoidance position, the motor 9 is turned off, the locking component is controlled to move to the locked position, and the connection between the power supply of the electric heating body 6 and the power supply of the air conditioner is connected; the entire air conditioner is started, and the air conditioner is switched from heating mode to cooling mode. Compared with the air conditioner with electric heating function in the prior art, the air conditioner of the present invention gives up the air duct when cooling, increases the air volume, and improves the cooling efficiency. In addition, because the electric heating body 6 is in the avoidance position and isolated from the interior of the air conditioner, no condensation water will appear on the electric heating body 6 in the cooling mode, reducing the probability of failure of the electric heating body 6.
[0052] When the air conditioner switches from cooling mode to heating mode, first cut off the connection between the power supply of the electric heating body 6 and the power supply of the air conditioner, start the motor 9 connected to the rotating shaft 8 to control the electric heating body 6 to move from the avoidance position to the heating position; control the locking component to move to the unlocking position so that the pulley can move in the slide rail, and through the movement of the pulley and the extension and retraction of the retractable connecting rod, the isolation plate 5 moves to the non-isolated position with the electric heating body 6; when the electric heating body 6 reaches the heating position, turn off the motor 9, control the locking component to move to the locking position, and connect the power supply of the electric heating body 6 and the power supply of the air conditioner; the controller controls the electric heating body 6 and the air conditioner to start, thereby realizing the conversion of the air conditioner from the cooling mode to the heating mode.
[0053] When the electric heating body 6 fails and the electric heating body 6 is in the heating position, a fault alarm is first issued, then the connection between the power supply of the electric heating body 6 and the power supply of the air conditioner is cut off, and the motor 9 driven by the rotating shaft 8 is started to control the electric heating body 6 to move from the heating position to the avoidance position; when the electric heating body 6 reaches the avoidance position, the motor 9 is turned off and the power to the motor 9 is cut off; due to the presence of the isolation plate 5, the electric heating body 6 can be completely isolated from the entire air conditioner, protecting other components from damage when the electric heating body 6 fails. Secondly, in the cooling mode of the air conditioner, the isolation plate 5 also plays a role in establishing an air duct, preventing the intake air flow from forming turbulence due to entering the avoidance position, thereby interfering with the normal operation of the air conditioner and causing the loss of air volume.
[0054] In addition, when the electric heating body 6 fails or needs to be replaced, the electric heating body 6 can be directly removed and replaced by simply removing the screws 13 and opening the protective shell 12. There is no need to remove the entire outer shell 100 of the air conditioner, which reduces the difficulty of repairing and replacing the electric heating body 6.
[0055] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
[0056] The electric heating component 2 of the present invention is arranged in the housing 100 of the electrical equipment, and the electric heating component 2 includes: a rotating shaft 8, which is rotatably arranged on the housing 100; an electric heating body 6, which includes a heating position located inside the housing 100 to heat the intake air flow and a avoidance position located outside the housing 100 to avoid the intake air flow. The electric heating body 6 is fixedly connected to the rotating shaft 8 to rotate with the rotating shaft 8 to switch between the heating position and the avoidance position; wherein, an avoidance groove 7 is provided on the housing 100, and the avoidance groove 7 is located on the movement path of the electric heating body 6 to avoid the movement of the electric heating body 6. In this way, the electric heating component 2 of the present invention is installed on an air conditioner with heating requirements. When the air conditioner is heating, the electric heating body 6 can be moved to the heating position, that is, the air outlet side of the fan, to realize the function of heating the incoming air flow. When the air conditioner is cooling, the electric heating body 6 can be moved to the avoidance position to keep the air duct of the air conditioner smooth, reduce the air volume loss during cooling, improve the cooling efficiency, and avoid the occurrence of condensation water on the electric heating component in the cooling mode. It solves the problem in the prior art that the electric heating device of the air conditioner is prone to condensation water when the air conditioner is in the cooling mode, thereby causing electric heating failure. When repairing and replacing the electric heating component, there is no need to remove the entire panel of the air conditioner, which improves the efficiency of repairing and replacing the electric heating component, and can cut off the power to the electric heating component when it fails to avoid burning other components, thereby protecting other components of the air conditioner.
