Description

Technical Field

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

[0002] An air source heat pump is an energy-saving device that transfers heat energy from a low-temperature heat source to a high-temperature heat source by consuming a part of high-grade energy (mechanical energy, electric energy or high-temperature heat energy) as compensation, and its efficiency is directly proportional to the heat exchange efficiency of the evaporator. Compared with traditional air-conditioning systems, air source heat pumps have advantages such as high efficiency and energy saving, safety and environmental protection. Air source heat pumps are usually installed outdoors and do not occupy indoor space. However, due to site restrictions, some air source heat pumps installed outdoors are directly exposed to the open-air environment, resulting in the equipment inside the air source heat pump being extremely vulnerable to extreme weather such as heavy rain. Over time, the aging speed of the equipment is accelerated, leading to a shortened service life of the air source heat pump.

Filtering the air entering the air source heat pump avoids the accumulation of floating dust and other sundries in the air source heat pump, so that the heat dissipation and operation of the equipment in the air source heat pump are not affected by floating dust and other sundries; however, there are still the following defects in the implementation process:

[0004] In the implementation process of the above patent document, although it solves the problems that the air source heat pump is directly exposed to the open-air environment, affected by extreme weather such as heavy rain and filtering the air to avoid the accumulation of floating dust and other sundries in the air source heat pump, there are problems that the filtering components of the device are not easy to clean and the device is prone to frosting in cold weather.

Detailed implementation manners

[0033] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] Example 1, as Figure 1-2 shown, an air source heat pump device includes four support legs 1. The upper ends of the four support legs 1 are fixedly connected to a body group 2 together. An exhaust top 5 is provided on the upper side of the body group 2. A filter protective cover 3 is provided on the upper part of the outer surface of the body group 2. A cleaning mechanism 4 is provided on the outer surface of the filter protective cover 3. A shielding mechanism 6 is provided jointly on the upper sides of the cleaning mechanism 4 and the exhaust top 5. Electric telescopic rods 7 are provided on the lower parts of the left and right sides of the body group 2 respectively. The output ends of the two electric telescopic rods 7 are fixedly connected to the lower parts of the left and right sides of the cleaning mechanism 4 respectively.

[0035] It should be noted that the exhaust top 5 is composed of a top cover and an exhaust fan. In the present invention, the specific installation method, the connection method of the circuit and the control method of the exhaust fan and the electric telescopic rod 7 are all conventional designs and are the conventional design means of designers.

[0036] First, by installing four support legs 1, the device is raised above the ground to prevent excessive water accumulation at the bottom from penetrating into the device for too long and corroding the internal components of the device. The body group 2 and the exhaust top 5 are used in cooperation to complete the absorption of heat in the air and transfer the absorbed heat to the water that needs to be heated. This process is repeated until the water temperature reaches the predetermined temperature. By installing the shielding mechanism 6, the device is prevented from being directly exposed to the open environment, which may cause the equipment in the air source heat pump to be extremely vulnerable to extreme weather such as heavy rain. At the same time, by setting up the filter protection cover 3, floating dust and other debris in the air are prevented from entering the device, which may affect the heat dissipation and operation of the device. When the air humidity is too high, part of the moisture in the air can also be filtered to prevent water vapor in the air from condensing into frost on the surface of the evaporator 24 when the environmental temperature is lower than the lowest working temperature set by the device, which may affect the working efficiency of the device. At the same time, by setting up the cleaning mechanism 4, under the drive of the shielding mechanism 6 and the electric telescopic rod two 7, the dust and frost on the filter protection cover 3 are removed.

[0037] To achieve the transfer of the heat absorbed from the air to the water that needs to be heated, as Figure 3 shown, the body group 2 includes a body shell 21 fixedly connected to the upper ends of the four support legs 1. The bottom wall of the inner cavity of the body shell 21 is provided with a circulation component 22. The upper side of the inner cavity of the body shell 21 is provided with an evaporator 24. The evaporator 24 and the circulation component 22 are connected by a conduit. The lower side of the middle part of the front end of the body shell 21 is provided with a shell door 23. The lower sides of the left and right ends of the body shell 21 are respectively fixedly connected to the lower sides of the closer ends of the two electric telescopic rods two 7.

[0038] It should be noted that the specific installation methods and connection methods of the circuit and control methods of the circulation component 22 and the evaporator 24 in the present invention are all conventional designs, which are the conventional design means of designers. Among them, the circulation component 22 includes devices such as a compressor, a condenser, an expansion valve, and a pipeline connected to an external water tank.

[0039] By setting up the evaporator 24, the contact area with the air is increased, and the working efficiency of the device is improved. In cooperation with the circulation component 22 and the exhaust top 5, the liquid working medium first absorbs heat in the air in the evaporator 24 and evaporates to form steam. Then the steam is compressed into a high-temperature and high-pressure gas by the compressor, enters the condenser to release heat to the water that needs to be heated, and then condenses into a liquid state. The liquid working medium expands through the expansion valve and then returns to the evaporator 24 again, continues to absorb heat in the air and transfers the absorbed heat to the water that needs to be heated. This process is repeated until the water temperature reaches the predetermined temperature.

[0040] Example 2, on the basis of Example 1, to prevent the device from being directly exposed to the open environment, which may cause the equipment in the air source heat pump to be extremely vulnerable to extreme weather such as heavy rain, as Figure 4As shown in the figure, the shielding mechanism 6 includes two L-shaped plates 61, and the two L-shaped plates 61 are symmetrically arranged left and right. Fixed groups 66 are provided on the upper sides of the opposite surfaces of the two L-shaped plates 61. Electric telescopic rods 62 are provided at the upper ends of the two L-shaped plates 61 in the horizontal direction. Tooth engaging components 63 are provided at the output ends of the two electric telescopic rods 62. The middle parts of the two tooth engaging components 63 are respectively meshed and connected with the middle parts of the two fixed groups 66. A front flip cover group 65 is jointly provided on the front sides of the two fixed groups 66, and a rear flip cover group 64 is jointly provided on the rear sides of the two fixed groups 66.

[0041] It should be noted that the tooth engaging component 63 is composed of a rectangular plate and two rack plates, and the two rack plates are installed at the diagonal corners of the upper end of the rectangular plate. In the present invention, the specific installation method, circuit connection method, and control method of the electric telescopic rod 62 are all conventional designs and are the conventional design means of designers.

[0042] When the device is not in use or in extreme weather such as heavy rain, it is necessary to shield the upper part of the device. Therefore, fixed groups 66 need to be installed on the left and right sides of the upper end of the exhaust top 5. By starting the electric telescopic rods 62 on both sides, the tooth engaging components 63 are driven to move upward, and then the front flip cover group 65 and the rear flip cover group 64 are driven to rotate and unfold between the two fixed groups 66. At this time, when the device is in use, the air circulation is smooth. In non-extreme weather such as heavy rain, such operations can be performed. When the front flip cover group 65 and the rear flip cover group 64 need to be closed, the electric telescopic rods 62 on both sides are started to drive the tooth engaging components 63 to move downward, and then the front flip cover group 65 and the rear flip cover group 64 are driven to rotate and close between the two fixed groups 66 to protect the device.

[0043] Furthermore, as Figure 5 shown, each of the two fixed groups 66 includes a mounting plate 661. The middle parts of the mutually remote ends of the two mounting plates 661 are respectively fixedly connected to the two L-shaped plates 61. Ring-shaped guide rail frames 662 are provided on the mutually remote sides of the upper ends of the two mounting plates 661. Support frames 663 are provided in the middle of the inner surfaces of the two ring-shaped guide rail frames 662. Transmission components 664 are provided in the middle of the two support frames 663. The outer surfaces of the two transmission components 664 are respectively meshed and connected with the two tooth engaging components 63. The lower ends of the two mounting plates 661 are respectively fixedly connected to the left and right sides of the upper end of the exhaust top 5.

[0044] It should be noted that both of the two transmission components 664 are composed of a long rod and two gears. The two gears can rotate on the long rod and are adapted to the gear teeth component 63. The long rod in the transmission component 664 is fixedly installed in the middle of the support frame 663. At the same time, the gear on the side close to the annular guide rail frame 662 is fixedly connected to the front flip cover group 65 on the same side, and the gear on the side far from the annular guide rail frame 662 is fixedly connected to the rear flip cover group 64 on the same side. Therefore, when the gear teeth component 63 moves up and down, it will drive the two gears in the transmission component 664 to rotate in the opposite direction on the long rod, and then drive the rear flip cover group 64 and the front flip cover group 65 to rotate around the long rod in the transmission component 664 as the center and rotate and unfold or close in the inner cavity of the annular guide rail frame 662.

[0045] Furthermore, as Figure 6 shown, the front flip cover group 65 includes two symmetrically arranged connecting frames two 652. One ends of the two connecting frames two 652 close to each other respectively penetrate through the inner cavities of the two annular guide rail frames 662 and are jointly fixedly connected with a front cover body 651. A second slot 653 is arranged on the upper side of the inner surface of the front cover body 651. The inner cavities of the two connecting frames two 652 are respectively rotationally connected to one sides of the outer surfaces of the two transmission components 664 close to each other.

[0046] Specifically, the sides of the connecting frames two 652 far from each other are respectively fixedly connected to the gears on the side of the transmission component 664 close to the annular guide rail frame 662, and the connecting frames two 652 are sleeved on the long rod in the transmission component 664 and can drive the gears in the transmission component 664 to rotate on the long rod. Therefore, when the gear teeth component 63 moves up and down, it will drive the gears fixedly connected to the connecting frames two 652 to rotate, and then the connecting frames two 652 drive the front cover body 651 to rotate.

[0047] Furthermore, as Figure 7 shown, the rear flip cover group 64 includes two symmetrically arranged connecting frames one 641. One ends of the two connecting frames one 641 close to each other respectively penetrate through the two annular guide rail frames 662 and are jointly fixedly connected with a rear cover body 642. A first slot 643 is arranged on the upper side of the outer surface of the rear cover body 642. The inner cavity of the first slot 643 fits with the inner cavity of the second slot 653. The inner cavities of the two connecting frames one 641 are respectively rotationally connected to the middle parts of the outer surfaces of the two transmission components 664.

[0048] Specifically, the two sides of the first connecting frame 641 that are far away from each other are respectively fixedly connected to the gears on the side of the transmission component 664 that is far away from the annular guide rail frame 662. Moreover, the first connecting frame 641 is sleeved on the long rod in the transmission component 664 and can drive the gears in the transmission component 664 to rotate on the long rod. Therefore, when the gear tooth component 63 moves up and down, it will drive the gears fixedly connected to the first connecting frame 641 to rotate, and then the first connecting frame 641 drives the rear cover body 642 to rotate, so that the front cover body 651 and the rear cover body 642 rotate and unfold or rotate and close. And by setting the second slot 653 and the first slot 643, when the front cover body 651 and the rear cover body 642 are closed, it can prevent rainwater from passing through the closing part of the front cover body 651 and the rear cover body 642 and then entering the device through the exhaust top 5, which will affect the service life of the device.

[0049] Embodiment 3. On the basis of Embodiment 1 and Embodiment 2, this embodiment is to clean the dust on the surface of the attached filter protective cover 3 and the frost formed in cold weather, as Figure 8 shown. The cleaning mechanism 4 includes two L-shaped rods 46 respectively fixedly connected to the front and rear sides of the lower ends of the two gear tooth components 63. The opposite surfaces of the two symmetrically arranged L-shaped rods 46 are fixedly connected with a first cleaning plate 41 together. The front side and the rear side of the lower end of the first cleaning plate 41 are both provided with symmetrically arranged first connecting rods 42 on the left and right. The lower ends of the four first connecting rods 42 are jointly provided with a second cleaning plate 43. The front side and the rear side of the lower end of the second cleaning plate 43 are both provided with symmetrically arranged tooth plates 44 on the left and right. The lower sides of the four tooth plates 44 are jointly provided with a cleaning component 45. Both the first cleaning plate 41 and the second cleaning plate 43 are sleeved on the upper side of the outer surface of the filter protective cover 3.

[0050] First of all, it should be noted that the first cleaning plate 41 and the second cleaning plate 43 are arranged in a rectangular shape and sleeved on the upper side of the outer surface of the filter protective cover 3. The two L-shaped rods 46 on the same side are respectively fixedly connected to the front and rear sides of the lower end of the gear tooth component 63 on the same side. Through the up and down movement of the gear tooth component 63, the L-shaped rods 46 are driven to move up and down. With the cooperation of the four first connecting rods 42, the first cleaning plate 41 and the second cleaning plate 43 are driven to move up and down, so that the first cleaning plate 41 and the second cleaning plate 43 clean the upper and middle parts of the outer surface of the filter protective cover 3. Through the second cleaning plate 43, the four tooth plates 44 are driven to move up and down. Through the four tooth plates 44, the electric telescopic rods 7 on both sides are started at the same time, so that the cleaning component 45 moves up and down on the lower and middle parts of the outer surface of the filter protective cover 3 and then cleans, and at the same time knocks on the outer surface of the filter protective cover 3, making the cleaning of the outer surface of the filter protective cover 3 more thorough.

[0051] Furthermore, as Figure 9 and Figure 10As shown in the figure, the cleaning component 45 includes a third cleaning plate 451. Sliding grooves 453 are symmetrically arranged on the left and right sides of the rear side of the front end and the front side of the rear end of the third cleaning plate 451. On the upper left and right sides of the third cleaning plate 451, symmetric second connecting rods 452 are arranged front and back. The upper ends of the four second connecting rods 452 are fixedly connected to a fourth cleaning plate 455 together. Installation grooves 456 are symmetrically arranged on the left and right sides of the rear side of the front end and the front side of the rear end of the fourth cleaning plate 455. In the inner cavities of the four installation grooves 456, third gears 457 are arranged. The four third gears 457 are respectively meshed with four toothed plates 44. The mutually remote ends of the two third gears 457 on the same side respectively penetrate through the inner cavity of the installation groove 456 and are fixedly connected with first bevel gears 458. On the front and back sides of the fourth cleaning plate 455, cleaning groups one 454 are symmetrically arranged. On the left and right sides of the fourth cleaning plate 455, cleaning groups two 459 are symmetrically arranged. The third cleaning plate 451 and the fourth cleaning plate 455 are both sleeved on the lower side of the outer surface of the filter protection cover 3. The middle parts of the lower left and right sides of the two third cleaning plates 451 are respectively fixedly connected to the output ends of two second electric telescopic rods 7.

[0052] Specifically, it should be noted that the third cleaning plate 451 and the fourth cleaning plate 455 are arranged in a rectangular shape and sleeved on the lower side of the outer surface of the filter protection cover 3. By starting the second electric telescopic rods 7 and cooperating with the four second connecting rods 452, the third cleaning plate 451 and the fourth cleaning plate 455 are driven to move up and down at the middle and lower parts of the outer surface of the filter protection cover 3 and clean the filter protection cover 3. At the same time, by the downward movement of the four toothed plates 44, the four third gears 457 are respectively driven to rotate. Through the rotation of the third gears 457, the first bevel gears 458 fixedly connected to the third gears 457 are driven to rotate and the cleaning groups one 454 are driven to knock on the outer surface of the filter protection cover 3. Through the rotation of the first bevel gears 458, the cleaning groups two 459 are driven to knock on the outer surface of the filter protection cover 3, making the cleaning of the filter protection cover 3 more thorough.

[0053] To realize knocking on the front and rear ends of the filter protection cover 3, as Figure 11 shown, the two cleaning groups one 454 both include first installation shells 4541 fixedly connected to the front and back sides of the fourth cleaning plate 455 respectively. On the mutually close sides of the inner cavities of the two first installation shells 4541, four first springs 4544 are arranged. The other ends of the four first springs 4544 on the same side are fixedly connected to a first knocking frame 4542 together. On the mutually remote sides of the two first knocking frames 4542, first convex rods 4543 are arranged. The left and right ends of the two first convex rods 4543 penetrate through the fourth cleaning plate 455 and are respectively fixedly connected to the third gears 457 on the same side.

[0054] It should be noted that the mating surfaces of the first knocking frame 4542 and the first convex rod 4543 are adapted to each other. The first knocking frame 4542 can slide back and forth in the inner cavity of the first mounting shell 4541. The left and right ends of the two first mounting shells 4541 are respectively mounted on the left and right sides of the concave surfaces on the front and rear sides of the fourth cleaning plate 455, and there is a gap between the front-side first mounting shell 4541 and the rear side wall of the front-side concave surface. The dust and frost to be cleaned can pass through the middle. Through the rotation of the third gear 457, the first convex rod 4543 is driven to rotate and cooperate with the first spring 4544, so as to reciprocally compress the first knocking frame 4542, achieving the purpose of reciprocally knocking the outer surface of the filter protection cover 3, oscillating the attachments such as dust or frost remaining on the outer surface of the filter protection cover 3, and making the cleaning more thorough.

[0055] To achieve knocking on the left and right ends of the filter protection cover 3, as Figure 12 shown, the two second cleaning groups 459 both include the second mounting shells 4592 respectively fixedly connected to the left and right sides of the fourth cleaning plate 455. On the side close to each other in the inner cavities of the two second mounting shells 4592, two second springs 4593 are fixedly connected. The other ends of the two cleaning components 45 on the same side are commonly fixedly connected to the second knocking frame 4591. On the sides far away from each other of the two second knocking frames 4591, there are second convex rods 4594. The front and rear ends of the two second convex rods 4594 respectively penetrate through the inner cavities of the second mounting shells 4592 and are fixedly connected with second bevel gears 4595. On the sides far away from each other of the two second bevel gears 4595 on the same side, they are respectively meshed and connected with the two first bevel gears 458.

[0056] It should be noted that the mating surfaces of the second knocking frame 4591 and the second convex rod 4594 are adapted to each other. The second knocking frame 4591 can slide left and right in the inner cavity of the second mounting shell 4592. The two second mounting shells 4592 are respectively mounted on the left and right ends of the fourth cleaning plate 455, and there is an interval between the second mounting shell 4592 and the fourth cleaning plate 455. The dust and frost to be cleaned can pass through the middle. Through the rotation of the third gear 457, the first bevel gear 458 is driven to rotate. Through the first bevel gear 458, the second bevel gear 4595 is driven to rotate, and then the second convex rod 4594 is driven to rotate and, in cooperation with the second spring 4593, the second knocking frame 4591 is reciprocally compressed, achieving the purpose of reciprocally knocking the outer surface of the filter protection cover 3, oscillating the attachments such as dust or frost remaining on the outer surface of the filter protection cover 3, and making the cleaning more thorough.
