Description

Technical Field

[0001] The utility model relates to the technical field of heat pump equipment, in particular to a heat pump device with a flow guide structure. Background Art

[0002] An air source heat pump is an energy regeneration device that uses air thermal energy for heating. It is frequently used in cold water water heaters, hot and cold air conditioners, and heating systems. For example, the hot water for bathing that we use daily requires an air source heat pump so that the water temperature can rise in a very short time. Another example is the heating state of the air conditioner, which is also inseparable from the air source heat pump.

[0003] However, the structure of the air source heat pump in the prior art generally takes in air from the back and discharges air on the left and right sides of the front panel. In order to increase the air outlet area, some designs also add air outlets on the top of the equipment, so that the heat pump can not only discharge air from the left and right sides, but also from the top at the same time when running, thereby optimizing the heat exchange effect of the heat pump equipment and improving the heat dissipation performance of the heat pump.

[0004] However, in actual use, since there is an air outlet on the top of the heat pump equipment, rain or water droplets will fall through the air outlet into the heat pump equipment and directly fall onto the turbine blades inside the heat pump, which will destroy the dynamic balance of each turbine blade during operation, and in severe cases may even damage the entire turbine fan.

[0046] like Figures 1 to 7As shown, a heat pump device with a guide structure in this embodiment includes a housing 1, an upper air outlet 2 is formed on the top of the housing 1, a turbine fan 3 is installed inside the housing 1, the turbine fan 3 is located below the upper air outlet 2, and a guide structure for shielding the top of the turbine fan 3 is installed below the upper air outlet 2, and the water falling from the upper air outlet 2 is shielded by the guide structure and guided to flow out from a position away from the turbine fan 3. It can be understood that by adding a guide structure inside the housing 1 of the heat pump, the guide structure is arranged below the upper air outlet 2 and shields the top of the turbine fan 3, and the water falling from the upper air outlet 2 is shielded by the guide structure and guided to flow out from a position away from the turbine fan 3, the external water can be effectively blocked from dripping down onto the turbine fan inside the heat pump device, and the turbine fan is effectively protected to ensure the stable operation of the turbine fan and each turbine blade on the turbine fan.

[0047] In one embodiment, specifically, the guide structure includes a baffle plate 4 and a guide plate 5, the baffle plate 4 is installed between the upper air outlet 2 and the turbine fan 3, the guide plate 5 is installed below the baffle plate 4, and the baffle plate 4 extends downwardly and obliquely to the top of the guide plate 5, and the guide plate 5 and the turbine fan 3 are staggered in the lateral direction. The guide plate 5 and the turbine fan 3 are staggered in the lateral direction, which can be understood as the outer edge of the projection of the guide plate 5 on the horizontal plane protrudes from the outer edge of the projection of the turbine fan 3 on the horizontal plane.

[0048] It can be understood that since the baffle plate 4 is installed between the upper air outlet 2 and the turbine fan 3, the baffle plate 4 can be used to effectively block the water droplets falling from the upper air outlet 2, preventing the water droplets from falling downward into the turbine fan 3, and since the baffle plate 4 is tilted downward and extends above the guide plate 5, the baffle plate 4 can guide the falling water droplets to flow along the inclined surface of the baffle plate 4 and drip onto the guide plate 5. Furthermore, since the guide plate 5 and the turbine fan 3 are staggered from each other in the lateral direction, the water that falls into the guide plate 5 will not drip onto the turbine fan 3 when it continues to flow downward, thereby effectively guiding the water to flow out to a position away from the turbine fan 3.

[0049] In one embodiment, specifically, the upper surface edge of the shielding plate 4 is integrally formed with a first flange 6 that is bent upward, so the first flanges 6 at the edge of the shielding plate 4 can be used to limit the dripping water from overflowing to the surrounding areas. In addition, the shielding plate 4 is provided with a notch 7, which is located at the lower end of the inclined surface of the shielding plate 4 and above the guide plate 5, so that the water can be effectively guided to automatically flow to the notch 7 along the inclined surface of the shielding plate 4 and continue to drip smoothly from the notch 7 to the guide plate 5.

[0050] In one embodiment, specifically, a first side air outlet 8 and a second side air outlet 9 are respectively formed on the left and right sides of the outer shell 1, and the number of the baffles 4 is several. Optionally, in this embodiment, the number of the baffles 4 is three, and each baffle 4 is arranged in parallel along the length direction of the guide plate 5, and each baffle 4 forms a guide gap 10 between each other, and the upper outlet of the guide gap 10 is inclined toward the upper air outlet 2, and the lower outlet of the guide gap 10 is inclined toward the first side air outlet 8. In addition, an air guide plate 11 is installed at a position close to the second side air outlet 9. After the air guide plate 11 is extended obliquely along the diameter direction of the turbine fan 3, the air guide plate 11 is close to the outer edge of the turbine fan 3.

[0051] It can be understood that in the above structure, by forming the first side air outlet 8 and the second side air outlet 9 on the left and right sides of the shell 1, the air outlet area of ​​the heat pump can be significantly increased, thereby improving the heat exchange effect and heat dissipation performance of the heat pump. At the same time, by setting the number of shielding plates 4 to be multiple, and arranging the shielding plates 4 in parallel with each other, and forming guide gaps 10 between the shielding plates 4, when the turbo fan 3 drives the air to flow inside the heat pump, the airflow inside the heat pump can smoothly flow upward through the guide gaps 10, so that each shielding plate 4 can not only shield the water droplets for the turbo fan 3, but also ensure that the airflow generated by the turbo fan 3 flows out smoothly, and avoid the shielding plate 4 at the top of the turbo fan 3 blocking the upward outflow of the airflow. In addition, since the upper outlet of the guide gap 10 is inclined toward the upper air outlet 2, and the lower outlet of the guide gap 10 is inclined toward the first side air outlet 8, when the airflow moving in the heat pump hits the inclined surface of the baffle plate 4, a part of it can be guided to flow directly to the upper air outlet 2 along the guide gap 10, and a part of it can be guided to flow directly to the first side air outlet 8 along the guide gap 10. The airflow inside the heat pump can be made to flow out more smoothly; furthermore, since the two ends of the inclined air guide plate 11 are respectively close to the second side air outlet 9 and the turbine fan 3, the air guide plate 11 can play a role in guiding the flow of air between the second side air outlet 9 and the turbine fan 3. Therefore, when the airflow generated by the turbine fan 3 hits the surface of the air guide plate 11, the air guide plate 11 can guide the airflow to flow directly to the second side air outlet 9, so that the airflow inside the heat pump can be made to flow out more smoothly from the other side. Through the above-mentioned flow guide structure, it can be ensured that the moving airflow inside the heat pump flows out more smoothly and quickly from the upper side, left side and right side of the heat pump, so as to effectively improve the heat exchange effect and heat dissipation performance of the heat pump.

[0052] In one embodiment, specifically, each side edge of the guide plate 5 is integrally formed with a second flange 12, a third flange 13 and a fourth flange 14, wherein the second flange 12 and the third flange 13 are both extended upward at the edge of the guide plate 5, the third flange 13 is located on the side close to the turbine fan 3, and the second flange 12 is provided with two, the two second flanges 12 are distributed at opposite ends of the third flange 13, and the two second flanges 12 are respectively butted with the third flange 13, so when the water falls downward onto the surface of the guide plate 5, the two second flanges 12 can be used to The edge 12 limits the overflow of water to the left and right sides, and the third flange 13 can also be used to limit the overflow of water in the direction of the turbine fan 3, ensuring that the water can be discharged in a directional manner. At the same time, since the fourth flange 14 is located on the side of the guide plate 5 away from the turbine fan 3, and the fourth flange 14 extends downward, the fourth flange 14 extending downward can be used to guide the water to continue to flow downward. Therefore, when the water drops onto the surface of the guide plate 5, the water can continue to flow along the surface of the fourth flange 14, effectively guiding the water to flow out to a position away from the turbine fan 3.

[0053] In one embodiment, preferably, a plurality of water flow holes 15 are opened on the guide plate 5, and each water flow hole 15 is arranged along the length direction of the guide plate 5, so that the water dripping onto the surface of the guide plate 5 can continue to be discharged downward through each water flow hole 15, and because each water flow hole 15 is far away from the turbine fan 3 in the lateral direction, that is, the outer edge of the projection of each water flow hole 15 on the horizontal plane protrudes beyond the outer edge of the projection of the turbine fan 3 on the horizontal plane, each water flow hole 15 can effectively guide the water to flow out to a position away from the turbine fan 3.

[0054] In one embodiment, preferably, the water flow hole 15 is an L-shaped hole, and the L-shaped hole spans from the surface of the guide plate 5 to the fourth flange 14. Therefore, when the water on the guide plate 5 flows out along the surface of the fourth flange 14, it can also continue to be discharged downward through the L-shaped hole at the same time.

[0055] In one embodiment, specifically, a drain board 16 is installed at the bottom of the outer shell 1, and the drain board 16 corresponds to the bottom of the guide plate 5, and a plurality of drain holes 17 are opened on the drain board 16, so that the water dripping downward from the guide plate 5 can be uniformly collected by the drain board 16 and can be discharged outward through the plurality of drain holes 17 on the drain board 16, effectively avoiding the accumulation of water inside the heat pump equipment.

[0056] In one embodiment, specifically, a plurality of supporting feet 18 are fixedly installed on the bottom of the outer shell 1, and the drain board 16 is lifted upward by each supporting foot 18, so as to ensure that a ground clearance is formed between each drainage hole 17 on the drain board 16 and the ground, thereby ensuring that the water can be smoothly discharged from the heat pump equipment.

[0057] In one embodiment, specifically, the housing 1 includes an air inlet mesh plate 19 installed on the rear side and an air outlet mesh plate 20 installed on the front side, the upper air outlet 2 is formed at the top of the air outlet mesh plate 20, and the first side air outlet 8 and the second side air outlet 9 are formed on the left and right sides of the air outlet mesh plate 20. Therefore, when the turbine fan 3 inside the heat pump is running, the air inside the heat pump is continuously discharged from the upper air outlet 2, the first side air outlet 8 and the second side air outlet 9 of the air outlet mesh plate 20, and the external air continuously and automatically enters from the mesh holes of the air inlet mesh plate 19 and is replenished to the interior of the heat pump. At the same time, a fin heat exchanger 21 and a fan mounting frame 22 are installed in the housing 1. The fan mounting frame 22 is located between the fin heat exchanger 21 and the air outlet mesh plate 20, and the fin heat exchanger 21 is close to the air inlet mesh plate 19. Therefore, when the external air enters the heat pump through the air inlet mesh plate 19, the fin heat exchanger 21 can be used to exchange heat with the airflow, and the turbo fan 3 is installed on the fan mounting frame 22, and the fan mounting frame 22 is used to support and connect the turbo fan 3. Furthermore, an air baffle 23 is also installed between the turbo fan 3 and the air outlet mesh plate 20, and the opposite sides of the shielding plate 4 are respectively connected to the fan mounting frame 22 and the air baffle 23, so that the shielding plate 4 is stably installed between the fan mounting frame 22 and the air baffle 23, and one side of the guide plate 5 is connected to the air baffle 23 to ensure the stable installation of the guide plate 5. In addition, since the air shielding plate 23 is added between the turbo fan 3 and the air outlet mesh plate 20 , the heat exchange with the air outlet mesh plate 20 can be reduced, thereby helping to reduce the formation of condensed water inside the heat pump and on the air outlet mesh plate 20 .

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
