Description

[0001] The present invention relates to the technical field of air source heat pump maintenance, and particularly to a defrosting device and an air source heat pump. Background Art

[0002] An air source heat pump is an energy-saving device that uses high-level energy to make heat flow from a low-level heat source (such as air) to a high-level heat source. It can be used for heating and cooling and is a form of heat pump that can convert low-level heat energy that cannot be directly utilized (such as the heat contained in air, soil, and water) into high-level heat energy that can be utilized, thereby achieving the purpose of saving some high-level energy (such as coal, gas, oil, electric energy, etc.). When an air source heat pump unit operates in a low-temperature environment, frosting will occur. When the frost accumulates to a certain extent, the frost needs to be removed; otherwise, it will affect the normal operation and service life of the air source heat pump.

[0017] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] When the air source heat pump works in a low-temperature environment, it is easy to frost. The existing methods for defrosting the air source heat pump basically rely on manual cleaning, which not only increases the workload of people, but also is easy to be forgotten, thus affecting the normal use of the air source heat pump and reducing the service life of the equipment. To solve this technical problem, the present invention provides a defrosting device and an air source heat pump with the defrosting device. It can be understood that the defrosting device can also be used for defrosting other devices similar to the air source heat pump. The present invention only takes the application of the defrosting device to the air source heat pump as an example for illustration, and the principle of applying the defrosting device to other devices is the same as that of the present invention. Any direct substitution made on the basis of the present invention is within the protection scope of the present invention.

[0019] Figure 1 The overall structural schematic diagram of the defrosting device 100 of the present invention installed on the air source heat pump is given, as Figure 1 shown, the defrosting device 100 provided by the present invention includes a fixing component 110 and a heating component 120. One end of the fixing component 110 is installed on the air source heat pump; the heating component 120 is installed on the fixing component 110, and the heating component 120 forms a heating surface, and the heating surface contacts the outer side surface of the air source heat pump to melt and remove the frost on the air source heat pump.

[0020] In the above technical solution of the present invention, it can be first fixed on the air source heat pump through the fixing component 110, and then the heating surface formed by the heating component 120 can bake and melt the frost on the outer side of the air source heat pump, achieving the defrosting effect. Therefore, the defrosting device 100 provided by the present invention can replace manual defrosting of the air source heat pump, reducing people's workload and avoiding the adverse effects on the air source heat pump caused by people forgetting to defrost.

[0021] In addition, the heating component 120 can also increase the temperature of the surrounding air, playing a role in delaying frosting.

[0022] In actual use, since frosting occurs on the outer side of the air source heat pump, although the above technical solution of the present invention can play a defrosting role, the defrosting range is limited. Therefore, it is necessary to make the heating component 120 have a movable function. In this way, a larger range of defrosting can be performed on the outer side of the air source heat pump.

[0023] Based on this, in one embodiment, the defrosting device 100 further includes a moving component 130 and a driving component 140. The two ends of the moving component 130 are respectively slidably connected to the upper and lower sides of the frame 112. The driving component 140 is installed on the side of the frame 112 and is in transmission connection with the moving component 130. The heating component 120 is arranged on the moving component 130. The heating component 120 moves left and right on the frame 112 through the action of the moving component 130, so that the heating surface can contact the outer side of the air source heat pump at different positions to melt and remove the frost at each position, achieving the purpose of thorough defrosting.

[0024] The structure of the defrosting device provided by the present invention will be described in detail below.

[0025] As Figure 2 shown, the fixing component 110 includes a connecting block 1111, a fixing block 1112, and an adsorption magnet 1113. The two ends of the connecting block 1111 are respectively connected to the frame 112 of the fixing block 1112, specifically connected to the top of the vertical rod 1121. The adsorption magnet 1113 is arranged on the side of the fixing block 1112 close to the air source heat pump. Since the outer side of the air source heat pump is mostly a metal surface, the defrosting device can be adsorbed on the outer side of the air source heat pump through the adsorption magnet 1113.

[0026] In one embodiment, the frame 112 is a rectangular structure formed by sequentially connecting two vertical rods 1121 and two horizontal rods 1122 end to end. The fixing components 110 are respectively arranged at the tops of the two vertical rods 1121. Slide grooves 1122a are formed on the opposite surfaces of the two horizontal rods 1122. The two ends of the moving component 130 are respectively slidably connected in the two slide grooves 1122a. The heating component 120 is arranged on the moving component 130, and the driving component 140 is arranged on one of the vertical rods 1121.

[0027] In this embodiment, the moving component 130 can move in the slide groove 1122a driven by the driving component 140, thereby driving the heating component 120 to move left and right on the frame 112.

[0028] In one embodiment, the heating component 120 includes an electric heating block 121 and a wiping cotton cloth 122. The electric heating block 121 is arranged on the moving component 130. The electric heating block 121 is equipped with its own power supply device. The surface of the electric heating block close to the air source heat pump forms the heating surface. The wiping cotton cloth 122 is also arranged on the moving component 130 and is located on both sides of the heating surface. When the electric heating block 121 melts the frost on the air source heat pump into water, and under the movement of the moving component 130, the wiping cotton cloth 122 can wipe off the melted water to protect the air source heat pump. Further, the electric heating block 121 is a common electric heating element in the art.

[0029] In one embodiment, the moving component 130 includes a slider 131 and a moving rod 132. The slider 131 is slidably connected to the slide groove 1122a. The two ends of the moving rod 132 are respectively fixedly connected to the two sliders 131 and are connected to the driving component 140. The heating component 120 is arranged on the side of the moving rod 132 close to the air source heat pump.

[0030] In one embodiment, the moving rod 132 includes a first moving rod 1321 and a second moving rod 1322. The driving component 140 includes a first driving component and a second driving component. The first driving component and the second driving component are respectively arranged on the two vertical rods 1121. The first moving rod 1321 and the second moving rod 1322 are arranged side by side. The first moving rod 1321 is connected to the first driving component, and the second moving rod 1322 is connected to the second driving component.

[0031] It should be noted that in this embodiment, the first moving rod 1321 and the second moving rod 1322 have the same structure, and the first driving component and the second driving component also have the same structure. Therefore, only the first moving rod 1321 and the first driving component will be described below, and the structures of the second moving rod 1322 and the second driving component can be referred to those of the first moving rod 1321 and the first driving component.

[0032] As Figures 3 - 7 shown, in one of the embodiments, the first driving component includes a storage battery 141, a wire drum 142, a power connection seat 143, a first conductive contact 144, a power connection slip ring 145, a second conductive contact 146, a spring 147, an electromagnet 148, and a permanent magnet 149. The storage battery 141 and the permanent magnet 149 are sequentially arranged inside the vertical rod 1121 from near the fixing component 110 to away from the fixing component 110. The electromagnet 148 is arranged inside the first moving rod 1321. The moving component 130 further includes a sleeve rod 133 arranged in the chute 1122a. The wire drum 142 is arranged inside the sleeve rod 133 and is connected to the vertical rod 1121 at one end. The power connection seat 143 is arranged at the end of the wire drum 142 away from the vertical rod 1121 and is connected to the storage battery 141 through an electric wire. The first conductive contact 144 is arranged at the end of the power connection seat 143 away from the wire drum 142.

[0033] An opening 1331 is formed on one side of the sleeve rod 133. The slider 131 is sleeved outside the end of the sleeve rod 133 with the opening 1331. The power connection slip ring 145 is arranged inside the end of the sleeve rod 133 with the opening 1331. The outer wall of the power connection slip ring 145 is slidably connected to the inner wall of the sleeve rod 133 and the inner wall of the slider 131 respectively. The second conductive contact 146 is arranged on the side of the power connection slip ring 145 close to the first conductive contact 144. The electromagnet 148 is electrically connected to the second wire contact 156 through the power connection slip ring 145. The spring 147 is sleeved outside the wire drum 142 and is fixedly connected to the power connection slip ring 145 and the vertical rod 1121 at both ends respectively.

[0034] In one of the embodiments, the magnetic poles of the opposite faces of the two electromagnets 148 inside the first moving rod 1321 and the second moving rod 1322 are the same. The magnetic poles of the opposite faces of the electromagnet inside the first moving rod 1321 and the permanent magnet 149 inside the vertical rod 1121 close to it are the same. The magnetic poles of the opposite faces of the electromagnet inside the second moving rod 1322 and the permanent magnet 149 inside the vertical rod 1121 close to it are the same.

[0035] In one embodiment, a limiting component 150 is further included. The limiting component 150 is specifically a limiting block, and the limiting component 150 is sleeved on the outside of one end of the opening 1331 close to the wire cylinder 142.

[0036] In a second aspect, as Figure 1 shown, the present invention further provides an air source heat pump, which includes an air source heat pump main body 200 and at least one defrosting device 100. The defrosting device 100 is arranged on the outer side surface of the air source heat pump main body 200 through the fixing component 110.

[0037] In summary, the specific process of using the defrosting device provided by the present invention for defrosting the air source heat pump is as follows: First, place the fixing block 1112 on the top of the air source heat pump main body 200. The fixing block 1112 can be adsorbed on the top of the air source heat pump main body 200 through the fixing adsorption magnet 1113, so as to complete the installation of the defrosting component 100 on the outside of the air source heat pump main body 200. Then, turn on the storage battery 141 inside the two vertical rods 1121 to supply power to the first conductive contact 144. After that, the electricity is transmitted to the power receiving slip ring 145 through the second conductive contact 146 in contact with the first conductive contact 144, and then the current is transmitted to the built-in electromagnets 148 inside the first moving rod 1321 and the second moving rod 1322, so that the built-in electromagnets 148 have magnetism. And under the action of the instantaneous repulsive force of the corresponding built-in permanent magnets 149, the first moving rod 1321 and the second moving rod 1322 move on the outside of the air source heat pump main body 200. And when moving, the spring 147 can be stretched through the slider 131. When the spring 147 deforms to the topmost end, the spring 147 restores deformation and pulls the slider 131 to drive the first moving rod 1321 and the second moving rod 1322 to move back, so that the first moving rod 1321 and the second moving rod 1322 move reciprocally on the outside of the air source heat pump main body 200, driving the electric heating block 121 to move on the outside of the air source heat pump main body 200. The electric heating block 121 has its own power supply device, and will emit heat after being turned on, so as to heat the periphery of the air source heat pump main body 200, bake and melt the frost that has condensed on the surface of the air source heat pump main body 200, reduce the workload of the staff, and the wiping cotton cloth 122 can remove the water stains, and the defrosting effect is good, thereby increasing the service life of the air source heat pump unit; on the other hand, it can heat the surrounding air and delay frosting.

[0038] In addition, the limiting component 150 provided can limit the return position of the slider 131 to prevent the slider 131 from moving back and hitting the first conductive contact 144 with the second conductive contact 146.

[0039] The specific embodiments of the present invention described above do not limit the protection scope of the present invention. Any other corresponding changes and modifications made according to the technical concept of the present invention shall be included in the protection scope of the claims of the present invention.
