Description

Technical Field

[0001] This utility model relates to the field of heat pump equipment technology, and in particular to an air source heat pump heating component. Background Technology

[0002] An air source heat pump is an electric motor-driven device that utilizes the vapor compression refrigeration cycle principle to produce cold or hot air or cold or hot water using ambient air as a cold or heat source. Its main components include heat exchange equipment on the heat side, heat source side heat exchange equipment, and a compressor. The air source heat pump uses the heat in the air as a low-temperature heat source, which undergoes heat exchange through the condenser or evaporator of a traditional air conditioner. Then, through a circulation system, it extracts or releases heat energy, transferring it into the building to meet users' needs for domestic hot water, underfloor heating, or air conditioning.

[0003] Patent document CN219414953U discloses an air source heat pump heating assembly, including a heat pump main unit, a fixing mechanism, and a dustproof mechanism. A fan is installed on the upper part of the heat pump main unit. The dustproof mechanism includes a mounting base, which is fixedly installed on the side wall of the heat pump main unit, and a first filter screen is fixedly installed on the side wall of the mounting base; a mounting bracket, which is slidably installed in the inner cavity of the mounting base, and sliders are symmetrically fixedly installed on the side wall of the mounting bracket; a first sliding groove, which is symmetrically opened on the side wall of the mounting base and is slidably connected to the sliders; and a second filter screen, which is fixedly installed on the side wall of the mounting bracket, and the diameter of the second filter screen is smaller than that of the first filter screen.

[0004] Although the aforementioned air source heat pump heating components can solve the corresponding technical problems, if the filter screen is not cleaned in time during use, dust may clog the filter screen, which may reduce the heat dissipation performance of the equipment and thus affect the normal use of the equipment. There is still room for improvement.

[0005] Therefore, an air source heat pump heating component is proposed. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 An embodiment of this utility model provides an air source heat pump heating component, including: an air source heat pump main unit, a cleaning mechanism 2 disposed on the top of the air source heat pump main unit 1, and a sealing mechanism 3 for fixing the filter screen 4. A slot 101 is provided on one side of the air source heat pump main unit 1, and the filter screen 4 is inserted into the slot 101. A forward and reverse motor 106 is installed on the other side of the air source heat pump main unit 1, and fan blades are installed on the forward and reverse motor 106.

[0024] A metal mesh 105 is installed at the motor of the forward and reverse motor 106 on one side of the air source heat pump unit 1. By installing the metal mesh 105, it can prevent rats from entering the air source heat pump unit 1 and causing equipment failure, thus greatly ensuring the normal operation of the equipment.

[0025] The sealing mechanism 3 includes a housing 302, which is fixedly connected to a slot 101 on one side of the air source heat pump unit 1. A sealing plate 303 is slidably connected inside the housing 302, and the sealing plate 303 is used to fix the filter screen 4. A handle 304 is fixedly connected to one end of the sealing plate 303, and the handle 304 slides in the middle of the housing 302. By setting up the sealing mechanism 3 and using the sealing plate 303 to slide in the slot 101, it can seal one side of the filter screen 4 inserted in the slot 101, preventing edge gaps from causing dust to enter the interior of the air source heat pump unit 1, thereby reducing the performance of the equipment.

[0026] The cleaning mechanism 2 includes support plates 202, which are symmetrically fixed to one side of the top of the air source heat pump unit 1. A screw 205 is rotatably connected between the two support plates 202. A slider 204 is screwed onto the surface of the screw 205. A brush strip 208 is mounted on one side of the slider 204 via bolts 209, and the bristles on one side of the brush strip 208 abut against one side of the filter screen 4. By setting up the cleaning mechanism 2, the rotation of the screw 205 drives the slider 204 to move on the screw 205, thereby driving the brush strip 208 mounted on the slider 204 to clean the surface of the filter screen 4, thus removing the dust filtered from the surface of the filter screen 4. This significantly extends the equipment's maintenance time, reduces maintenance operations by personnel, and saves time and effort.

[0027] One end of the screw 205 passes through one of the support plates 202 and is fixedly connected to the rotating shaft of the motor 206. The motor 206 is fixedly installed on one side of the air source heat pump unit 1. The motor 206 is electrically connected to the controller 207 via wires. The controller 207 is also fixedly installed on one side of the air source heat pump unit 1. By setting the controller 207 to control the forward and reverse rotation of the motor 206, the brush strip 208 can reciprocate on the filter screen 4, thereby cleaning the surface of the filter screen 4. The controller 207 can operate automatically under the program, which greatly extends the maintenance time of the equipment.

[0028] Among them, the controller 207 adopts a DSP controller with the model number TMS320F2812.

[0029] The slider 204 has a guide rod 203 slidably connected to its middle section. Both ends of the guide rod 203 are fixed to the support plate 202, and a protective cover 201 is installed on the top of the support plate 202. By setting the guide rod 203, the slider 204 can drive the brush strip 208 to operate stably on the air source heat pump unit 1. The protective cover 201 installed on the top of the support plate 202 protects the moving parts from damage caused by debris.

[0030] The working principle of this utility model is as follows: When in use, the equipment is stably fixed on the platform. After the air source heat pump host 1 has been running for a period of time, the cleaning mechanism 2, under the control of the controller 207, starts the motor 206 to drive the slider 204 to reciprocate on the screw 205, thereby driving the brush strip 208 installed at one end of the slider 204 to clean the surface of the filter screen 4. At the same time, the forward and reverse motor 106 at one end of the air source heat pump host 1 works in coordination to blow the dust on the filter screen 4 in the opposite direction, thereby removing the dust filtered on the surface of the filter screen 4, which greatly extends the maintenance time of the equipment, reduces the maintenance operations of the staff, and saves time and effort.

[0031] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
