Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary devices for air conditioners, and in particular to an auxiliary ceramic insulating electric heater for air conditioners. Background Art

[0002] In modern air conditioning systems, the need to heat and maintain the temperature of liquid and gaseous media is extremely common. Auxiliary electric heaters for air conditioners are key to achieving this goal. By guiding the medium under pressure through the heating chamber, they apply the principles of fluid thermodynamics to evenly remove the heat generated by the heating element, thereby raising the temperature of the heated medium to the user's process requirements.

[0003] However, existing auxiliary electric heaters for air conditioners have exposed numerous practical problems. Some products have complex structural designs, which not only increases the difficulty and cost of the manufacturing process but also leads to cumbersome installation procedures, making it difficult for maintenance personnel to quickly locate faulty components. Furthermore, the heating components of traditional electric heaters are often fixed in place. Failure or performance degradation often requires extensive disassembly of the entire unit, resulting in time-consuming repairs and severely impacting the normal operation of the air conditioning system.

[0004] Many electric heaters lack flexible and effective control mechanisms for media flow direction, making it difficult to precisely adjust the flow rate and direction of the media according to different operating conditions. This results in low heating efficiency and energy waste. Furthermore, when heating components need to be replaced or maintained, traditional electric heaters cannot guarantee that they can be operated in a power-off state, which can easily lead to the risk of electric shock and pose a safety hazard to maintenance personnel.

[0005] To address these problems, it has become an urgent task in the industry to develop an air-conditioning auxiliary electric heater with a reasonable structural design, controllable costs, easy installation, precise control of medium flow direction, convenient replacement of heating components, and high safety.

[0032] like Figure 5 As shown, the specific structure of the interchangeable heating mechanism 4 includes a heat-conducting seat 41, a heat-conducting sheet 42, a heating rod 43, a clamping mechanism 44, a ceramic cover 45, a plug 46 and a socket 47; the outer upper side of the heat-conducting seat 41 is connected to the inner upper side of the outer shell 1 through the clamping mechanism 44, the inner lower side of the heat-conducting seat 41 is fixedly connected to the heating rod 43, and the two outer side surfaces of the lower side of the heat-conducting seat 41 are fixedly connected to a number of heat-conducting sheets 42; the center of the lower side of the ceramic cover 45 is fixedly connected to the top of the heat-conducting seat 41, the inner lower left side of the ceramic cover 45 is fixedly connected to the plug 46, and the upper side of the plug 46 is electrically connected to the heating rod 43 through a wire; the socket 47 is fixedly connected to the inner upper side of the outer shell 1, and the upper side of the socket 47 is electrically connected to the lower side of the plug 46.

[0033] like Figure 6As shown, the specific structure of the clamping mechanism 44 includes a clamping slot 441, a latch 442, a second guide hole 443, a spring 444, a connecting slot 445 and an operating rod 446; the clamping slot 441 is opened on the upper right side of the thermal conductive seat 41; the second guide hole 443 is arranged inside the upper side of the outer shell 1, and a connecting slot 445 is opened on the upper right side of the second guide hole 443; the outside of the latch 442 is laterally movably connected to the inside of the second guide hole 443, the outside of the left side of the latch 442 is connected to the inside of the clamping slot 441, the upper right side of the latch 442 is fixedly connected to the operating rod 446, and the outside of the operating rod 446 is movably connected to the inside of the connecting slot 445, and a spring 444 is provided between the right side of the latch 442 and the right side of the inside of the second guide hole 443.

[0034] A handle is provided at the center of the upper side of the ceramic cover 45 ; and a slope is provided on the upper left side of the latch 442 .

[0035] The usage status of the present invention is as follows: the present invention has a reasonable and simple structure, low production cost, and easy installation. When in use, the medium to be heated is first introduced through the input connector 9, and the medium enters the cutting and changing mechanism 3 through the connecting hole 8, and then is heated by the interchangeable heating mechanism 4, and finally the heated medium is output from the output connector 6. The interchangeable heating mechanism 4 can be replaced as needed, and the cutting and changing mechanism 3 is used to control the flow direction of the medium. When in use, the medium to be heated first enters the connecting hole 8 from the input connector 9. Since the connecting hole 8 is connected to each cutting and changing mechanism 3, the medium will enter each cutting and changing mechanism 3 in turn for heating. Here, the guide housing 34 of the cutting and changing mechanism 3 can be moved up and down by the switching device 31. When the medium needs to be introduced into a certain interchangeable mechanism, When the heat exchanger 4 is under the lower part, the operator uses an Allen wrench to insert the Allen wrench into the Allen hole in the center of the lower side of the switching head 315, and rotates the switching head 315 to rotate the screw 314. When the screw 314 rotates, the guide block 313 threadedly connected to the screw 314 will move vertically in the guide hole 1 312, thereby driving the guide housing 34 to move up and down. When the guide housing 34 moves downward to the bottom, the medium can enter the space under the interchangeable heating mechanism 4 through the guide groove 35. The bottom surface of the guide groove 35 is in an arc shape, which is conducive to the flow of the medium and enables the medium to enter the lower part of the interchangeable heating mechanism 4 more smoothly. After the medium enters the lower part of the interchangeable heating mechanism 4, the heating rod 43 is energized and starts heating. The heat generated by the heating rod 43 is transferred to the medium through the installation heat-conducting seat 41 and the heat-conducting sheet 42. The quality increases the temperature of the medium. When replacing or cleaning the replaceable heating mechanism 4, first drive the guide shell 34 to move up to the top through the switching device 31. The sealing ring 36 at the edge of the top surface of the guide shell 34 can prevent external medium from entering the guide groove 35 and affecting the replacement of the replaceable heating mechanism 4. When the guide shell 34 moves to the top, the corresponding guide hole 7 position on the lower side will also be connected, which ensures that the medium will bypass the replaceable heating mechanism 4 that needs to be replaced. Then the operator pulls the operating rod 446, and the operating rod 446 drives the latch 442 to move to the right, compressing the spring 444, so that the left side of the latch 442 disengages from the slot 441. At this time, the handle in the center of the upper side of the ceramic cover 45 can be held to remove the replaceable heating mechanism 4 from the outer shell 1 for replacement. When the plug 46 is out, the power will be disconnected from the socket 47 to ensure safety during replacement. Then, when installing a new or cleaned replaceable heating mechanism 4, the heat-conducting seat 41 is aligned with the installation position on the upper side of the outer shell 1. Since the upper left side of the latch 442 is provided with a slope, when the heat-conducting seat 41 is pressed down, the latch 442 will be automatically squeezed to the right, and the spring 444 will be compressed. When the slot 441 is aligned with the latch 442, the spring 444 returns to its original state, and the latch 442 pops out to the left and is inserted into the slot 441, fixing the replaceable heating mechanism 4 on the outer shell 1. At the same time, the plug 46 will be inserted into the socket 47 to energize it, and then the switching device 31 will drive the guide housing 34 to move to the bottom, and then the medium can re-enter the guide groove 35 to be heated.This improves the convenience of replacement.
