Background Art

[0002] The essence of an air source heat pump is to use heat exchange with the air to cool or heat a building. The compressor conveys the medium to flow in the coil and contact the air. For example, the air source heat pump evaporator and air source heat pump with the announcement number CN110388767B in the prior art are used to solve the problems of the fast frost formation speed on the fin surface of the air source heat pump evaporator in the prior art, the fast frost layer blocking the channel speed, and the short defrost cycle. The air source heat pump evaporator includes a refrigerant pipe and a plurality of fins mounted in series on the refrigerant pipe. The design method is to design a guiding structure on the windward side of the fin that can guide the water vapor in the air to liquefy rather than condense, so that the water vapor in the air freezes instead of frosts, so as to achieve the purpose of extending the defrosting cycle, reducing the defrosting energy consumption, and improving the overall performance of the unit. The defrost cycle of the air source heat pump evaporator of the present invention under the same working conditions and defrosting conditions is about three times the original one, which greatly extends the defrost cycle and improves the working efficiency of the air source heat pump. The invention has a simple and reasonable structure, low cost, easy implementation, and has no effect on the normal operation of the system; Another example is an air source heat pump evaporator tower and air source heat pump system with announcement number CN110411069B.

Evaporator modules are arranged at intervals on the first cylindrical body and the second cylindrical body, and an air channel is arranged between the first cylindrical body and the second cylindrical body. The invention has a built-in soundproof wall to reduce the noise generated by the operation of the equipment. Adding a blower can greatly increase the circulation of air during the operation of the equipment, fix the direction of the wind flow, and reduce the impact of backflow. The spray structure on the evaporator module can greatly improve the working efficiency during refrigeration.

However, since this type of heat pump needs to frequently contact with the air for heat exchange when used outdoors, a large amount of dust is easily accumulated on the surface of the coil. Although the operation of the fan will carry away some of the dust through the airflow, the dust in the gaps cannot be effectively cleaned, and long-term accumulation will also lead to a decrease in the overall heat exchange efficiency of the coil.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 12 , the present invention provides the following technical solutions: Embodiment 1: In this embodiment, in order to solve the problems existing in the prior art, the following solution is disclosed, and the content of the solution is reflected in how to improve the effect of linkage dust prevention to ensure that a large amount of dust will not accumulate on the surface of the heat exchange tube after long-term use to affect the heat exchange effect. Figure 1-Figure 2 As shown, it includes a heat exchange area arranged on the body 1, and the side and top of the heat exchange area are a grille 3 and an air exchange port 2 respectively, and the coil 4 is also located in the heat exchange area. The fan in the air exchange port 2 runs to introduce airflow into the heat exchange area and exchange heat with the coil 4. The heat exchange area also includes a mobile cleaning mechanism, which is driven by a motor 9 installed on the body 1 and cleans the gap of the coil 4 through reciprocating movement. At the same time, the mobile cleaning mechanism also includes an airflow mechanism. The airflow mechanism generates linkage power and generates airflow to clean the coil 4 through the movement of the mobile cleaning mechanism. In actual use, it can be The program or manual control motor 9 is started at a fixed time. During the startup process, the screw 8 rotates synchronously, and the rotation effect generated by it drives the mobile cleaning mechanism to move back and forth along the surface of the coil 4 through the threaded transmission, thereby producing a cleaning effect. Moreover, when the mobile cleaning mechanism performs contact cleaning on the surface of the coil 4, it will also generate airflow through the effect of its own movement, and act on the surface of the coil 4 through the airflow mechanism, thereby achieving a better linkage dust prevention effect. The specific mobile cleaning mechanism includes the following contents: As mentioned above, the composition of the mobile cleaning mechanism is further disclosed in this scheme, as always Figure 1-Figure 3 As shown, the mobile cleaning mechanism includes a cleaning rod 5 slidably mounted on the body 1, and the top end of the cleaning rod 5 is threadedly connected to the screw 8 connected to the motor 9, and the cleaning rod 5 and the coil 4 are distributed parallel to each other as a whole. The surface of the cleaning rod 5 is installed with a cleaning piece 6 with bristles 7 on the inner wall. When the cleaning rod 5 moves back and forth, the bristles 7 are embedded in the gap of the coil 4. During the operation of the motor 9, the screw 8 rotates synchronously. At this time, under the threaded transmission action of the cleaning rod 5 and the cleaning rod 5, the cleaning rod 5 itself will reciprocate along the distribution direction of the coil 4. During the movement, the cleaning piece 6 installed on the cleaning rod 5 will move synchronously. Since the bristles 7 will be in the gap of the coil 4, the accumulated dust that is usually difficult to be directly cleaned will be cleaned more efficiently, thereby achieving a mobile cleaning effect.

[0020] Embodiment 2: This embodiment further discloses the following solution, namely, a solution for increasing the contact dimension between the cleaning member 6 and the coil 4, the specific contents are as follows: Figure 4 and Figure 6As shown, the cleaning rod 5 is divided into three sections, upper, middle and lower, wherein the upper section is used for threaded connection with the screw rod 8, and the lower section is slidably installed in the body 1, the upper and lower sections are fixedly connected, and the middle section is rotatably installed between the two sections and connected to the rotating mechanism, wherein the cleaning member 6 is also installed on the rotatable middle section, and the rotating mechanism is used to drive the middle section to rotate when the cleaning rod 5 moves horizontally, thereby improving the cleaning effect, and the rotating mechanism includes a rack 10 installed in the body 1, and the rack 10 is also meshed with a gear 11, and the gear 11 is installed on the rotating section of the cleaning rod 5. The reason why the cleaning rod 5 is designed into three sections is to enable the middle section to rotate in sections. In this way, after the gear 11 is installed on the middle section, during the overall movement of the cleaning rod 5, the meshing transmission between the gear 11 and the rack 10 can achieve the effect of allowing the middle section of the cleaning rod 5 to rotate around its own axis. Therefore, the cleaning member 6, especially the bristles 7 installed on the cleaning member 6, can improve the cleaning efficiency by fully moving on the surface of the coil 4.

[0021] In the present embodiment, a self-rotating mechanism is further provided in the cleaning rod 5, wherein the self-rotating mechanism is used to drive the cleaning member 6 to rotate around its own axis when the middle section of the cleaning rod 5 revolves. The reason for adopting the self-rotating mechanism is, on the one hand, to improve the cleaning effect of the bristles 7 on the coil 4, and on the other hand, when the bristles 7 as a whole follow the high-speed self-rotation of the cleaning member 6, the centrifugal force can be used to remove dust from the surface or gaps of the bristles 7, so as to avoid dust or other impurities with high viscosity from remaining in the bristles 7 and affecting the cleaning effect. The specific scheme is shown in the following content: In the present scheme, if Fig.10 As shown, the rotation mechanism includes a core shaft 13 whose two ends are respectively fixed to the upper and lower sections of the cleaning rod 5. The core shaft 13 movably penetrates the middle section of the cleaning rod 5, and the cleaning member 6 rotates to penetrate into the inside of the cleaning rod 5. At the same time, the bevel teeth 14 installed on the core shaft 13 mesh with the bevel teeth 14 on the inner end of the cleaning member 6. The middle section of the cleaning rod 5 is in a rotating state during the horizontal movement, and the core shaft 13 is in a relatively fixed state. At this time, since the cleaning rod 5 will drive the cleaning member 6 to revolve synchronously when rotating, the bevel teeth 14 installed at the inner end of the cleaning member 6 will be in a state of mutual meshing and transmission with the bevel teeth 14 on the core shaft 13. At this time, the cleaning member 6 will drive the bristles 7 to be in a synchronous rotation state, and the rotation speed is directly related to the rotation speed of the middle section. During the rotation of the bristles 7, the dust and debris attached to the surface of the bristles 7 will be directly thrown out, and in this way, the coil 4 can be more fully mechanically cleaned.

[0022] In this embodiment, the airflow mechanism is further disclosed in detail. Figure 10-12As shown, the airflow mechanism includes a fan blade 16 located inside the lower section of the cleaning rod 5, and the fan blade 16 is fixed to the bottom end of the fan shaft, and the fan shaft movably passes through the top wall of the lower section and extends to be fixed at the bottom end of the middle section. The cavity 15 where the fan blade 16 is located is connected with a swivel 18 through a connecting pipe 17. The swivel 18 rotatably installed on the outside of the middle section is connected with the internal space of the middle section of the cleaning rod 5 through a through hole provided on the middle section of the cleaning rod 5, and an air cavity 19 is provided inside the cleaning member 6, and the air cavity 19 is connected with the inside of the cleaning rod 5 through a first through hole 20, and the airflow also enters and exits from the second through hole 21 on the mounting surface of the bristle 7 on the cleaning member 6. The rotation of the middle section of the cleaning rod 5 will drive the fan shaft at its bottom end to rotate synchronously at high speed, so the fan blade 16 will have an airflow conveying effect under the synchronous rotation condition. Under normal conditions, the fan blade 16 rotates inside the lower section of the cleaning rod 5, and the airflow is transmitted through the connecting pipe 17 is transported to the rotating ring 18 and enters the middle section of the cleaning rod 5 through the through hole. Further airflow will enter the air cavity 19 through the first through hole 20 and finally be ejected from the second through hole 21. The ejected airflow has two functions. On the one hand, it can directly act on the coil 4 to improve the cleaning effect. On the other hand, it can utilize the characteristics of its revolution and the blown airflow to prevent dust from remaining in the space between the grille 3 and the coil 4. Moreover, during the return movement of the cleaning rod 5, the middle section will rotate in the opposite direction, that is, the synchronous rotation of the fan blades 16 will change the second through hole 21 from blowing to suction. In this way, in a complete moving process of the cleaning rod 5, the cleaning member 6 can achieve more modes of cleaning effects, and only needs to adopt a blade structure with a characteristic shape. Since it is fully disclosed in the prior art, it is not further limited in this application.

[0023] In this embodiment, a solution for further cleaning the bristles 7 is also disclosed. At the same time, the revolution of the bristles 7 can be used to realize the deformation and release of the bristles 7 and to strike and clean the coil 4. The specific contents are as follows: Figure 6-Figure 9 As shown, a baffle 12 fixed between the upper and lower sections is also provided on the back of the middle section of the cleaning rod 5. The inner wall of the baffle 12 is a non-planar structure. At the same time, the shortest distance between the two ends of the baffle 12 cross section and the axis of the cleaning rod 5 is less than the length of the bristles 7. During the rotation of the bristles 7 following the cleaning member 6, the inner ends thereof will intermittently contact the inner wall of the baffle 12, and the non-planar structure of the baffle 12 will fully contact the bristles 7, thereby realizing the self-cleaning of the bristles 7, and during the continuous revolution of the bristles 7, the bristles 7 will gradually be compressed by the inner wall of the baffle 12 and deformed, until they are out of contact, and the bristles 7 will instantly rebound and knock on the surface of the coil 4, thereby realizing the linkage multi-dimensional dust-proof cleaning purpose of the coil 4.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
