Description

TECHNICAL FIELD

[0001] The utility model belongs to air source heat pump hot air fan technical field, specifically relates to an air source heat pump hot air fan. BACKGROUND

[0002] With the continuous improvement of people's living standards and the pursuit of indoor environmental comfort, air source heat pump hot air fan as a kind of efficient, energy-saving air conditioning equipment, has been widely used in family, commercial and industrial fields.

[0003] In the operation process of air source heat pump hot air fan, in order to ensure the cleanliness inside the equipment and normal work, filtering the air entering the hot air fan is a crucial link. The traditional air source heat pump hot air fan is usually installed at the air inlet to block the dust, impurities and other pollutants in the air.

[0004] However, these traditional filter screen design has many obvious shortcomings. On the one hand, the traditional filter screen is mostly fixed installation and cannot be automatically replaced. With the growth of using time, a large number of impurities in the air will gradually accumulate on the surface of the filter screen, block its filter hole. This not only will seriously reduce the filtering effect of the filter screen, make the dirty air into the hot air fan, pollute and damage the internal components, but also will significantly reduce the air intake of the hot air fan. The reduction of air intake directly affects the working efficiency of the hot air fan, leads to its heating or cooling effect greatly discounted, can not meet the user's demand for indoor temperature.

[0005] On the other hand, in order to solve the problem of filter screen blockage, users often need to regularly manually disassemble and replace the filter screen. This process is not only cumbersome, time-consuming and laborious, but also requires users to have certain operation skills and tools. Moreover, frequent disassembly and installation operation is easy to cause the wear and tear of equipment components, such as the installation of filter screen, the connection part of air inlet, etc. The wear and tear of these components will increase the risk of failure of hot air fan in the running process, reduce the reliability and stability of the equipment, shorten its service life.

[0006] In addition, due to the traditional filter screen cannot effectively handle the blockage problem in time, the air intake efficiency of the hot air fan is difficult to be guaranteed. In the process of gradually blocking the filter screen, the air inlet resistance increases, and the air volume continues to decrease. This will lead to the hot air fan unable to stably output the required heat or cold, so that the indoor temperature fluctuates greatly, affects the user's experience, and also increases the energy consumption of the equipment.

[0007] To this end, the air source heat pump hot air machine is provided, which can automatically replace the filter surface, does not need to frequently disassemble and replace the filter screen, achieves the effect of saving time and effort, avoids the possible component wear caused by frequent disassembly and replacement of the filter screen, reduces the potential failure risk in the maintenance process of the hot air machine, improves the reliability and stability of the equipment, and ensures that the hot air machine always maintains good air inlet efficiency, so that the air volume is not reduced due to the blockage of the filter screen, thereby maintaining stable heating or cooling effect.

[0029] The working principle is as follows: firstly, the hot air fan body 1 is started, so that the air outside is filtered through the filter screen cloth 6, enters the hot air fan body 1 inside through the air inlet 2 and works; at this time, the impurities in the air are filtered (intercepted dust and impurities in the air) through the filter screen cloth 6, so that the clean air enters the hot air fan body 1 inside; after a period of filtering, the impurities in the air will cause the filter screen cloth 6 filter hole to be blocked; at this time, if it is not replaced, it may affect the normal operation of the equipment; at this time, the two rotating assemblies are rotated, one rotating assembly drives the corresponding winding roller 5 to wind the filter screen cloth 6, and the other rotating assembly drives the corresponding winding roller 5 to unwind the filter screen cloth 6, so that the filter screen cloth 6 moves in the first through slot 4, so as to achieve the effect of replacing the filter surface; the device can not only automatically replace the filter surface, but also does not need to frequently disassemble and replace the filter screen, so as to save time and effort, and at the same time, the possible part wear caused by frequent disassembly and replacement of the filter screen is avoided, the potential fault risk in the hot air fan maintenance process is reduced, the reliability and stability of the equipment are improved, and the hot air fan can always maintain good air inlet efficiency and stable heating or cooling effect without causing air volume reduction due to filter screen blockage.

[0030] The air inlet assembly comprises a shell 7 arranged at the position of the air inlet 2, a support is arranged in the shell 7, a first motor 8 is arranged on the support, a fan blade 9 is mounted at the output end of the first motor 8, the first motor 8 is supported by the support, and the fan blade 9 is driven to rotate by the first motor 8, so that the air outside enters the hot air fan body 1 inside for work.

[0031] The width of the first through slot 4 is greater than the width of the air inlet 2, which can cover the entire air inlet 2 with the filter screen cloth 6 inside the first through slot 4, so that all the air will pass through the filter screen cloth 6 before entering the device, which can better filter out dust and impurities.

[0032] The thickness of the first through slot 4 is the same as the thickness of the filter screen cloth 6, which can move smoothly inside the first through slot 4 without additional resistance from the side wall of the through slot because the thickness of the filter screen cloth 6 matches the thickness of the through slot.
