Description

Technical Field

[0001] The invention relates to the technical field of air heat source heating, and in particular to an air heat source heating system. Background Art

[0002] The air heat source heating system is a heating system that uses air as a heat source to provide heating or hot water. The commonly used equipment is the air source heat pump. Its principle is: to heat the gas or liquid by absorbing heat from the air through the refrigerant. It is often used in cold areas in the north.

[0003] The air source heat pump works intermittently during use. When the set temperature is reached, it will be in standby mode with an open top. If it rains or snows, snow and frost will cover the refrigerant pipe, making it difficult to exchange heat with the outside gas. When the heat pump is restarted, its working efficiency is greatly reduced. If the snow stops and the heat pump needs to be used later, it is necessary to manually clear the snow, which increases the difficulty of using it on rainy and snowy days. Not only that, due to the cold weather, there is a risk of freezing the pipes after the snow freezes. Summary of the invention

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure. Embodiment 1

[0035] See also Figure 1-2 , an air heat source heating system, comprising an air source heat pump body 1 and a heat preservation water tank, the air source heat pump body 1 and the heat preservation water tank are connected by a water pipe, the air source heat pump body 1 comprises a box body 11, an evaporator, a compressor, a circulation pump and a condenser are arranged in the box body 11, an air inlet 12 is opened at the outer end of the box body 11, an exhaust fan 14 is arranged on the top of the box body 11, and a snow shielding component 2 is arranged on the top of the box body 11;

[0036] In the prior art, the principle of the air source heat pump is: by absorbing heat from the air and transferring it to the room to heat the liquid, specifically, the evaporator is responsible for absorbing heat energy from the external air, the evaporator comprises a refrigerant pipe 13, the refrigerant pipe 13 is double-layered, and a special refrigerant (such as R410A, R32, etc.) is arranged in the outer layer. The refrigerant can absorb heat from the surrounding air at a lower temperature, and the inner layer is the water that needs to be heated. After the outer layer refrigerant exchanges heat with the air, it enters the compressor. The compressor is responsible for pressurizing the gas and raising the temperature. The condenser is responsible for releasing the heat energy of the heated gas and heating the water to the set temperature. The circulating pump is responsible for circulating the water of the air source heat pump with the water of the insulation water tank to raise the temperature again and again until it rises to 50-65 degrees. Its work is intermittent, and when the set temperature is reached, it will enter the standby state.

[0037] The snow shielding component 2 includes a tripod 21, an air outlet 22 is provided on the tripod 21, dust filters are provided in the air inlet 12 and the air outlet 22, a snow shield 23 is rotatably connected to the tripod 21, an elastic member 24 is provided between the snow shield 23 and the tripod 21, and the elastic member 24 can be an elastic rope. The tripod 21 is provided with a rain and snow sensing component 3;

[0038] The rain and snow sensing component 3 includes a snow storage hopper 31, and a driving component 4 is arranged under the snow storage hopper 31. When the snow storage hopper 31 is lowered by the gravity of rain and snow, the driving component 4 drives the snow shield 23 to rotate;

[0039] The snow shield 23 has three states, including a first state, a second state and a third state;

[0040] The first state is a vertical state, and the air outlet 22 is fully open; the second state is a horizontal state, and the air outlet 22 is half open, preventing rain and snow falling in a vertical direction from entering the box body 11; the third state is an oblique downward state, and the air outlet 22 is closed, preventing rain and snow falling in all directions from entering the box body 11.

[0041] When the machine enters the standby mode, if it snows lightly, the snow storage hopper 31 can store a certain weight of rain and snow, so that the snow shield 23 remains horizontal, preventing a large amount of rain and snow from falling vertically. If it continues to snow, the snow shield 23 will be tilted downward, completely blocking the air outlet 22, preventing rain and snow from entering the box body 11, thereby achieving the purpose of preventing rain and snow from entering the box body 11 when it snows, and effectively preventing rain and snow from covering the refrigerant pipe of the evaporator and reducing its heat exchange efficiency.

[0042] In an embodiment further provided by the present invention, the rain and snow sensing component 3 also includes a telescopic rod 32 arranged at the bottom of a snow storage hopper 31, and the number of the snow storage hoppers 31 is multiple. The bottom of the snow storage hopper 31 is fixedly connected to a top rod 33, and the bottom of the top rod 33 is fixedly connected to a wedge plate 34.

[0043] The telescopic rod 32 includes a hollow rod fixedly connected to the top of the tripod 21, a movable rod is slidably connected inside the hollow rod, the movable rod is fixedly connected to the bottom of the snow storage bucket 31, and the movable rod is fixedly connected to the inner bottom of the hollow rod.

[0044] Specifically, the number of the snow storage hopper 31 can be three, and the telescopic rod 32 is fixedly connected to the bottom of the snow storage hopper 31.

[0045] See also Figure 3-4 Furthermore, the driving component 4 includes a driving rod 41, a pair of sliders 42 are fixedly connected to the bottom of the driving rod 41, a plurality of guide grooves 43 are opened on the tripod 21, the sliders 42 slide inside the guide grooves 43, a pressure spring 44 is arranged between the sliders 42 and the guide grooves 43, and the pressure spring 44 is initially in a compressed state. A limiting component 5 is arranged on the driving component 4, which is responsible for preventing the driving rod 41 from sliding down.

[0046] The driving rod 41 is made of metal and is heavy. It cooperates with the pressure spring 44 to overcome the elastic member 24 and drive the snow shield 23 to rotate.

[0047] The limiting component 5 includes a special-shaped rod 51, and a reset telescopic component 52 is fixedly connected to the top of the tripod 21. The side end of the reset telescopic component 52 is fixedly connected to a limiting block 53. An inclined groove 54 is provided on the top of the limiting block 53. When the wedge plate 34 descends, the special-shaped rod 51 moves, driving the limiting block 53 to separate from the driving rod 41, thereby completing the purpose of self-rotation of the snow shielding plate 23.

[0048] The resetting telescopic member 52 includes a telescopic block with a telescopic structure, and a resetting spring is arranged inside.

[0049] Furthermore, the number of the resetting telescopic parts 52 and the limit blocks 53 is at least two, the special-shaped rod 51 includes a Z-shaped rod body 511, and the side end of the rod body 511 is connected to multiple wedge blocks 512, the wedge blocks 512 are in conflict with the inclined grooves 54 of the limit blocks 53, and when the driving rod 41 reaches the position of the second limit block 53, the snow shield 23 is in a horizontal state.

[0050] Specifically, the end of the rod body 511 is beveled and fits against the bevel of the wedge block 512. As can be seen from the figure, the volume of the second limiting block 53 is larger than that of the first limiting block 53. That is, when the first limiting block 53 moves, although the second limiting block 53 moves synchronously, it does not completely move out of the guiding groove 43. If the driving rod 41 approaches the second limiting block 53, it will still be blocked by the second limiting block 53.

[0051] The snow storage hopper 31 with an upward-opening frustum-shaped structure collects the falling rain and snow. When it reaches the first weight, the snow storage hopper 31 drives the ejector rod 33 and the wedge plate 34 to descend. The wedge plate 34 pushes the special-shaped rod 51 to slide obliquely downward. When the special-shaped rod 51 moves downward, it drives the wedge block 512 to move, causing the wedge block 512 to move the limiting block 53 a short distance, enabling the driving rod 41 to slide downward. Using the elastic force of the compression spring 44, the snow shielding plate 23 is pushed to rotate to the horizontal state, and the driving rod 41 stops when it reaches the next limiting block 53.

[0052] At this time, if it continues to snow or there is a tendency for the rain and snow to become heavier, the snow storage hopper 31 will drive the wedge plate 34 to continue to descend, squeezing the second limiting block 53 to move. When the second limiting block 53 separates from the driving rod 41, the driving rod 41 can continue to slide. At this time, the center of gravity of the snow shielding plate 23 is downward, and with the elastic force of the compression spring 44, the driving rod 41 will force the snow shielding plate 23 to continue to rotate until it fits against the inclined surface of the triangular frame 21 to block the air outlet 22. Embodiment 2

[0053] Please refer to Figure 5-7 , the difference between Embodiment 2 and Embodiment 1 is that the following technical features are added: A spare ventilation component 6 is arranged outside the box body 11. The spare ventilation component 6 includes a baffle 61 and a snow blocking cover 62 that are slidably connected to the outside of the box body 11. The bottom of the snow blocking cover 62 is open and is provided with a snow prevention net 63. The mesh holes of the snow prevention net 63 are smaller than those of the dust filter net. The baffle 61 and the snow blocking cover 62 are fixedly connected. A locking component 7 is arranged on the baffle 61, which is responsible for locking the position of the baffle 61 initially.

[0054] Specifically, a spare ventilation opening is also opened on the outside of the box body 11. Initially, the baffle 61 blocks the spare ventilation opening, and a snow prevention net 63 can also be arranged on the inner wall of the spare ventilation opening.

[0055] The locking component 7 includes a pull rod 71 fixedly connected to the top of the baffle 61. A top column 72 is fixedly connected to the bottom of the snow shielding plate 23. A locking block 73 is slidably connected to the triangular frame 21. A groove 74 is opened on the locking block 73. The pull rod 71 is in an inverted L shape and is initially hung on the locking block 73.

[0056] If at this time, the air source heat pump body 1 still wants to continue working (when the rain and snow are not heavy), it is necessary to open the backup channel. When the snow shield 23 falls, it brings the top column 72 down with it. The top column 72 is in free fall motion. After hitting the locking block 73, it pushes the locking block 73 to move, causing the pull rod 71 to lose the support of the locking block 73, thereby causing the baffle 61 and the snow cover 62 to fall. At this time, the fan is turned on to draw the internal cold air out through the backup vent. Through negative pressure, the outside gas enters the box body 11 through the bottom opening of the snow cover 62, thereby completing the purpose of ventilation. At this time, the heat of the outside air can still be used to exchange heat with the refrigerant. However, if the rain and snow continue to increase, you can choose to close the air source heat pump body 1.

[0057] In this embodiment, even when the air outlet 22 is completely blocked by the snow shield 23, the air source heat pump body 1 can still be operated for a period of time, and whether to continue to use it can be determined according to actual needs.

[0058] Furthermore, a support plate 64 is fixedly connected to the side end of the snow blocking cover 62, and a cleaning brush 65 is fixedly connected to the side end of the support plate 64 for cleaning impurities adhering to the dust filter.

[0059] If there is snow accumulation on the dust filter net, the cleaning brush 65 can be made to sweep the snow off when sliding downward, and a drainage hole is provided at the bottom of the casing 11. Embodiment 3

[0060] See also Figure 8 The difference between Example 3 and Example 2 is that the following technical features are added: a snow discharge component 8 is provided on the snow storage hopper 31, and the snow discharge component 8 includes a movable disk 81. The bottom of the snow storage hopper 31 is open (here it is different from the above), and is fixedly connected with a first magnetic ring 82. An annular groove is provided on the movable disk 81, and a second magnetic ring 83 is fixedly connected to the annular groove. Initially, the first magnetic ring 82 is magnetically connected to the second magnetic ring 83. When the snow storage hopper 31 reaches the set gravity, the first magnetic ring 82 is separated from the second magnetic ring 83 to pour out the rain and snow.

[0061] Specifically, a compression spring is fixedly connected between the snow storage hopper 31 and the movable rod, and the top of the movable plate 81 is semicircular.

[0062] When the snow storage hopper 31 is full of rain and snow, the weight reaches the rated value, and under the action of gravity, the first magnetic ring 82 and the second magnetic ring 83 are separated, and the rain and snow are finally poured out, and then the snow storage hopper 31 can return to the initial position.

[0063] Subsequently, it is only necessary to manually push the snow shield 23 up, and the snow shield 23 will rise with the driving rod 41 , and will successively squeeze the two limit blocks 53 until it is stuck on the first limit block 53 .

[0064] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
