Description

Technical Field

[0001] This utility model relates to the field of heat pump units, specifically a washing machine heating device based on heat pump electric water heating. Background Technology

[0002] With increasing environmental awareness and the promotion of energy conservation and emission reduction policies, the industrial laundry sector has higher and higher requirements for the energy-saving and environmentally friendly performance of hot water supply methods. Heat pump units, with their high efficiency and energy-saving characteristics, have become an important choice to meet this demand.

[0003] Heat pump units heat water by absorbing heat from the air and transferring it to the water. This heating method is not only energy-saving and environmentally friendly, but also provides a continuous and stable supply of hot water to meet the hot water needs of industrial laundry.

[0004] Existing heat pump units typically operate in outdoor environments. During use and observation, it has been found that dust and other impurities tend to accumulate on the surface of the radiator fins. These impurities can affect the heat exchange function between the fins and the air, thereby impacting the operation of the heat pump unit.

[0005] Therefore, a washing machine heating device based on heat pump electromechanical water heating is proposed to address the above problems. Utility Model Content

[0008] Preferably, a vertical rod is fixedly connected to the inner wall of the heat pump unit body; a baffle is fixedly connected to the end of the vertical rod; the baffle is located at the top of the cleaning pipe; a rotating wheel is rotatably connected to both sides of the baffle; the rotating wheel and the cleaning pipe are in contact; by setting the baffle, the water holes at the top of the cleaning pipe are blocked when the cleaning pipe rotates, reducing the interference of water flow diffusion on the axial flow fan, and also accelerating the flow rate of water sprayed from the other water holes, thereby improving the cleaning effect of the device on the radiator.

[0009] Preferably, multiple connecting rods are fixed to both sides of the baffle; the connecting rods and water holes are correspondingly arranged; multiple guide plates are fixed to the middle of the connecting rods; the guide plates are staggered; the guide plates are located between the cleaning pipe and the radiator; after the cleaning water is sprayed out of the water hole, it will pass through the connecting rod. Because the guide plate is inclined, the water will diffuse under the guidance of the guide plate when it passes through the connecting rod, further increasing the distribution range of water flow in the heat pump unit and improving the cleaning effect of the water flow on the radiator.

[0010] Preferably, a drain plate is fixed to the bottom of the radiator; the drain plate has a frustum structure; a drain pipe is provided in the middle of the heat pump unit body; the wastewater after cleaning the radiator will fall onto the surface of the drain plate. Because the drain plate has a frustum structure, the water will flow along the surface of the drain plate. This wastewater will be discharged through the drain pipe, reducing the wastewater accumulation in the heat pump unit body.

[0011] Preferably, the top of the drainage plate has a plurality of first drainage holes; the middle part of the drainage plate has a plurality of second drainage holes; the first drainage holes and the second drainage holes are connected; through the cooperation of the first drainage holes and the second drainage holes, the wastewater accumulated on the surface of the drainage plate will be discharged from the second drainage holes through the first drainage holes, reducing the water stains remaining on the surface of the drainage plate, and further reducing the wastewater accumulated in the heat pump unit.

[0012] Preferably, a filter screen is provided inside the connecting flange; the turbine is located between the cleaning pipe and the filter screen; by setting the filter screen, the cleaning water is filtered by the filter screen before entering the cleaning pipe through the connecting flange, and the filter screen will filter the impurities in the cleaning water, reducing the pollution effect of the impurities carried in the cleaning water on the radiator.

[0024] 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 scope of protection of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1 to 6 As shown in the figure, a washing machine heating device based on heat pump electric water heating according to an embodiment of the present invention includes a heat pump unit body 1. Multiple axial flow fans 12 are installed on the top of the heat pump unit body 1. Radiators 13 are symmetrically arranged inside the heat pump unit body 1. A connecting flange 14 is fixedly connected to the middle of the heat pump unit body 1. A cleaning pipe 15 is connected to the middle of the connecting flange 14. The cleaning pipe 15 is located between a pair of radiators 13. A turbine 16 is provided in the middle of the connecting flange 14. The turbine 16 and the cleaning pipe 15 are fixedly connected. Multiple water holes 17 are opened in the middle of the cleaning pipe 15. A water outlet pipe 18 is installed in the middle of the heat pump unit body 1. A compressor, condenser, and expansion valve are provided at the bottom of the heat pump unit body 1. The radiators 13 include fins and heat absorption pipes. The heated hot water is supplied to the intermediate water tank through the water outlet pipe 18. (Note: The valves shown in the figure are not explicitly stated.) As shown, the above are all common existing technologies. When it is necessary to clean the dust and impurities on the surface of the radiator 13, an external water pump can be connected to the connecting flange 14 to allow water to flow through the connecting flange 14 into the cleaning pipe 15. During the water flow, it will come into contact with the turbine 16. The turbine 16 will rotate under the impact of the water flow, and the cleaning pipe 15 will rotate with the turbine 16. After the water flows into the cleaning pipe 15, it will be sprayed out from the water hole 17 along with the rotating cleaning pipe 15. The water flow sprayed from the water hole 17 can spread to the surface of the radiator 13 to wash and clean the surface impurities, so as to achieve the cleaning work of the device on the surface fins of the radiator 13. Through the cooperation of the cleaning pipe 15 and the turbine 16, the cleaning pipe 15 will rotate with the turbine 16 under the action of the clean water flow, so as to expand the distribution range of the water flow in the heat pump unit body 1, so that the clean water will clean the surface of the radiator 13 evenly.

[0027] Please see Figures 3 to 5As shown, a vertical rod 2 is fixedly connected to the inner wall of the heat pump unit body 1; a baffle 22 is fixedly connected to the end of the vertical rod 2; the baffle 22 is located at the top of the cleaning pipe 15; a rotating wheel 23 is rotatably connected to both sides of the baffle 22; the rotating wheel 23 and the cleaning pipe 15 are in contact; when the axial flow fan 12 is working, it will generate cooling airflow to cool the internal components of the heat pump unit body 1, and when the cleaning water is sprayed out from the inside of the cleaning pipe 15 through the water hole 17, the water hole 17 located at the top will be blocked by the baffle 22, so that the water will not enter the inside of the axial flow fan 12 when it diffuses, thus reducing the interference of the water flow on the axial flow fan 12. When the top water hole 17 is blocked, the flow rate of the cleaning water at the remaining water holes 17 will increase due to the constant water pressure inside the cleaning pipe 15, thus enhancing the cleaning effect of the cleaning water on the radiator 13. At the same time, when the cleaning pipe 15 rotates, it will come into contact with the rotating wheel 23 and cause the rotating wheel 23 to rotate. The rotating wheel 23 will reduce the friction between the baffle 22 and the cleaning pipe 15. By setting the baffle 22, the top water hole 17 will be blocked when the cleaning pipe 15 rotates, reducing the interference of water flow diffusion on the axial flow fan 12. At the same time, it will also increase the flow rate of the water sprayed from the remaining water holes 17, thereby improving the cleaning effect of the device on the radiator 13.

[0028] Please see Figure 5 As shown, multiple connecting rods 3 are fixed to both sides of the baffle 22; the connecting rods 3 and the water holes 17 are correspondingly arranged; multiple guide plates 32 are fixed to the middle of the connecting rods 3; the guide plates 32 are staggered; the guide plates 32 are located between the cleaning pipe 15 and the radiator 13; after the cleaning water is sprayed out from the water hole 17, it will pass through the connecting rods 3. Because the guide plates 32 are inclined, the water will diffuse under the guidance of the guide plates 32 when it passes through the connecting rods 3, further increasing the distribution range of water flow in the heat pump unit body 1 and improving the cleaning effect of the water flow on the radiator 13.

[0029] Please see Figure 3 and Figure 6 As shown, a drain plate 4 is fixed to the bottom of the radiator 13; the drain plate 4 has a frustum structure; a drain pipe 42 is provided in the middle of the heat pump unit body 1; the wastewater after cleaning the radiator 13 will fall onto the surface of the drain plate 4. Because the drain plate 4 has a frustum structure, the water will flow along the surface of the drain plate 4. This wastewater will be discharged through the drain pipe 42, reducing the wastewater accumulation in the heat pump unit body 1.

[0030] Please see Figure 6As shown, the top of the drainage plate 4 is provided with a plurality of first drainage holes 5; the middle part of the drainage plate 4 is provided with a plurality of second drainage holes 52; the first drainage holes 5 and the second drainage holes 52 are connected; through the cooperation of the first drainage holes 5 and the second drainage holes 52, the wastewater accumulated on the surface of the drainage plate 4 will be discharged through the first drainage holes 5 and the second drainage holes 52, reducing the water stains remaining on the surface of the drainage plate 4, and further reducing the wastewater accumulated in the heat pump unit body 1.

[0031] Please see Figure 3 As shown, a filter screen 6 is provided inside the connecting flange 14; the turbine 16 is located between the cleaning pipe 15 and the filter screen 6; by setting the filter screen 6, the cleaning water will be filtered by the filter screen 6 before entering the cleaning pipe 15 through the connecting flange 14. The filter screen 6 will filter the impurities in the cleaning water, reducing the pollution effect of the impurities carried in the cleaning water on the radiator 13.

[0032] Working principle: The bottom of the heat pump unit 1 is equipped with a compressor, condenser, and expansion valve. The radiator 13 includes fins and heat absorption tubes. The heated water flows to the water tank through the outlet pipe 18. Other valves are not shown in the diagram. All of the above are common existing technologies. When cleaning dust and impurities from the surface of the radiator 13, an external water pump can be connected to the connecting flange 14 to allow water to flow through the flange 14 into the cleaning pipe 15. During the water flow, it will come into contact with the turbine 16, which will rotate under the impact of the water flow. The cleaning pipe 15 will also rotate along with the turbine 16. The rotating cleaning pipe 15 causes water to enter and then spray out through the water hole 17. The water sprayed from the water hole 17 can spread to the surface of the radiator 13 to wash away impurities, thus cleaning the fins of the radiator 13. When the axial fan 12 is working, it generates cooling airflow to cool the internal components of the heat pump unit 1. When the cleaning water is sprayed out from the cleaning pipe 15 through the water hole 17, the water hole 17 at the top is blocked by the baffle 22, preventing the water from entering the axial fan 12 during diffusion and reducing the water flow's impact on the axial fan 12. The top water hole 17 is obstructed, but the remaining water holes 17 will have a faster flow rate of cleaning water due to the constant water pressure inside the cleaning pipe 15, thus enhancing the cleaning effect of the cleaning water on the radiator 13. Simultaneously, the rotating cleaning pipe 15 will contact the impeller 23, causing it to rotate. The impeller 23 will reduce the friction between the baffle 22 and the cleaning pipe 15. After the cleaning water flows out of the water hole 17, it will pass through the connecting rod 3. Because the guide plate 32 is inclined, the water flow will diffuse under the guidance of the guide plate 32 as it passes through the connecting rod 3, further increasing the water pressure inside the heat pump unit body 1. The distribution range of the flow; the wastewater after cleaning the radiator 13 will fall onto the surface of the drain plate 4. Because the drain plate 4 is a truncated pyramid structure, the water will flow along the surface of the drain plate 4. This wastewater will be discharged through the drain pipe 42. Through the cooperation of the first drain hole 5 and the second drain hole 52, the wastewater accumulated on the surface of the drain plate 4 will be discharged through the first drain hole 5 and the second drain hole 52, reducing the water stains remaining on the surface of the drain plate 4. By setting the filter screen 6, the cleaning water will be filtered by the filter screen 6 before entering the cleaning pipe 15 through the connecting flange 14. The filter screen 6 will filter the impurities in the cleaning water.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
