[0002] Central air conditioners usually have an auxiliary heating function, which requires the use of an auxiliary heating device. Existing conventional auxiliary heating devices generally include a cylinder with a water inlet and a water outlet and a heating pipe arranged in the cylinder. The water in the cylinder is heated by the heating pipe to achieve hot water output.

[0003] The existing patent authorization number is: CN217423608U, which discloses a central air-conditioning auxiliary heater, including a vertically arranged cylinder, a heating tube located in the cylinder, and a water inlet near the bottom of the cylinder and a water outlet near the top of the cylinder arranged on the side wall of the cylinder. The heating tube extends vertically from the bottom of the cylinder into the inner cavity of the cylinder and the heating end of the heating tube is fixedly installed on the bottom of the cylinder; the above-mentioned heater avoids part of the heating tube from being exposed to the air, causing the heating tube to burn dry, thereby damaging the heating tube, and even causing safety accidents such as explosion. However, after analyzing the auxiliary heater, it was found that the way to prevent the heating tube from burning dry is to always keep the water level line on the upper side of the end of the heating tube. The premise for its realization is that it is necessary to ensure that there is sufficient water in the cylinder and the length of the heating tube should not be too long. However, in the actual operation process, it is not easy to always keep sufficient water in the cylinder. There is often a lack of water. Therefore, this structure has certain defects when used.

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a high-efficiency and energy-saving central air-conditioning auxiliary heater. Utility Model Content

A group of water level regulating plates are provided, which pass through the heating tube and transfer vertically. The water input into the heating cylinder is placed on the upper side of the water level regulating plate. When the water level regulating plate moves, the water level is adjusted to keep the heating tube immersed in water according to the amount of water to prevent it from burning empty. A group of lifting regulating cylinders are connected to the bottom of the heating cylinder. A lifting regulating mechanism for controlling the height of the water level inside the heating cylinder is provided inside the lifting regulating cylinder. The top of the lifting regulating mechanism is fixedly connected to the bottom of the water level regulating plate, so that the height of the water level regulating plate can be adjusted quickly and accurately according to requirements, thereby realizing automatic adjustment of the water level inside the heating cylinder.

[0007] Compared with the existing technology, the beneficial effect of the present invention is: on the basis of the existing heating tube inside the heating cylinder, a water level adjustment plate that moves up and down is set on the outside of the heating tube, and the water level adjustment plate is used to adjust the height of the water level inside the heating cylinder. According to the amount of water entering, the heating tube is controlled to be completely immersed in water, so as to achieve sufficient heating, while avoiding the heating tube being exposed to the air for empty burning, causing waste of resources and affecting the heating efficiency.

[0016] See also Figure 1-Figure 3, an efficient and energy-saving central air-conditioning auxiliary heater, comprising a heating cylinder 10, a water inlet 11, and a water outlet 12; the heating cylinder 10 is vertically arranged and one side of which is fixed by multiple sets of mounting brackets 13, the water inlet 11 and the water outlet 12 are respectively arranged on the lower side wall and the upper side wall of the heating cylinder 10 distributed relative to the mounting bracket 13, and a plurality of heating pipes 15 are vertically distributed inside the heating cylinder 10, and the bottom ends of the heating pipes 15 are commonly connected to a junction box 26, which is connected to the junction box 26 to drive the heating pipes 15 to generate heat, thereby heating the water input into the heating cylinder 10 along the water inlet 11, and then outputting it through the water outlet 12 to realize the heating process, and a set of water pipes 15 are arranged in a lifting manner inside the heating cylinder 10 The water level regulating plate 17 is vertically transferred through the heating tube 15, and the water input into the heating cylinder 10 is placed on the upper side of the water level regulating plate 17. When the water level regulating plate 17 moves, the water level is adjusted to keep the heating tube 15 immersed in water according to the amount of water to prevent it from burning empty. A group of lifting regulating cylinders 16 are connected to the bottom of the heating cylinder 10. A lifting regulating mechanism for controlling the height of the water level inside the heating cylinder 10 is provided inside the lifting regulating cylinder 16. The top of the lifting regulating mechanism is fixedly connected to the bottom of the water level regulating plate 17. In this way, the height of the water level regulating plate 17 can be adjusted quickly and accurately according to requirements, thereby realizing automatic adjustment of the water level inside the heating cylinder 10.

[0017] In the embodiment of the present invention, a pressure relief valve 14 is provided on the top of the heating cylinder 10. The pressure relief valve 14 is mainly used to protect the heating cylinder 10 from damage caused by excessive pressure. When the pressure exceeds the set safety value, the pressure relief valve will automatically open to release the pressure. Due to the abnormal increase in pressure, if there is no pressure relief valve, the heating cylinder may rupture due to excessive pressure, resulting in equipment damage and potential safety accidents.

[0018] A plurality of fixing rods 27 are installed at equal intervals in a ring on the outer wall of the junction box 26. The ends of the fixing rods 27 are fixed to the inside of the heating cylinder 10 to keep the position of the junction box 26 and the heating tube 15 fixed. A heating tube hole 19 is opened at the movable connection between the heating tube 15 and the water level adjustment plate 17. A buffer sealing layer is provided on the inner side of the heating tube hole 19 to ensure smooth sliding between the heating tube 15 and the water level adjustment plate 17 while preventing the flow of liquid on the upper and lower sides. At the same time, a sealing ring 18 is installed on the circumferential outer wall of the water level adjustment plate 17, and the sealing ring 18 is in sliding and sealing contact with the inner wall of the heating cylinder 10.

[0019] In one embodiment of the present invention, the operating range of the water level regulating plate 17 is set between the water inlet 11 and the bottom of the heating cylinder 10 to prevent the water level regulating plate 17 from crossing the water inlet 11 and the water input along the water inlet 11 from being placed under the water level regulating plate 17, thereby affecting the return movement of the water level regulating plate 17.

[0020] It should be noted that in order to keep the water inside the heating cylinder 10 heated by the heating tube 15 in a short time, it is also necessary to keep the heating tube 15 at a certain length. Therefore, for the operation of raising and lowering the water level regulating plate 17 and adjusting the water level inside the heating cylinder 10, the water content also needs to be kept within a certain range.

[0021] As a preferred embodiment of the present invention, the lifting and adjusting mechanism includes support rods 20 fixedly installed and evenly distributed on the bottom of the water level line adjusting plate 17. The bottom ends of the support rods 20 are connected to a positioning ring 21. One side of the positioning ring 21 is connected to a nut 24 through a connecting rod 22. The nut 24 is provided with a guide device for limiting its rotation. A vertical screw 23 is threadedly connected to the middle part of the nut 24. The top of the screw 23 is rotatably connected to the inner wall of the lifting and adjusting cylinder 16 through a bearing, and a servo motor 25 is connected to the bottom end. A heat-insulating protective shell is provided on the outside of the servo motor 25. The servo motor 25 is started to drive the screw 23 to rotate, thereby driving the nut 24 to move up and down along the screw 23. In this way, under the connection of the connecting rod 22, the positioning ring 21 and the support rod 20, the height of the water level line adjusting plate 17 placed inside the heating cylinder 10 is adjusted.

[0022] The working principle of the present utility model is: in the idle part of the device, all the above-mentioned driving parts, which refer to power elements, electrical components and adaptive power supplies, are connected through wires, and the electrical connections are completed in a working order. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control. During operation, according to the amount of water input into the heating cylinder 10 from the water inlet 11 and the height of the heating tube 15, when the water inlet cannot completely immerse the heating tube 15, the servo motor 25 is started to drive the screw 23 to rotate, and then the nut 24 is driven to control the water level adjustment plate 17 to move upward. At this time, as the water level adjustment plate 17 moves, the water level inside the heating cylinder 10 gradually rises until the heating tube 15 is immersed. Then, as the junction box 26 is powered on, the heating tube 15 is controlled to operate, the immersed water is heated, and then discharged through the water outlet 12, and then cooperated with the air conditioner to perform auxiliary heating.
