A dishwasher capable of recovering heat energy from wastewater

Abstract

This utility model relates to the field of dishwasher technology, and in particular to a dishwasher capable of recovering heat energy from wastewater. It includes a dishwasher body, a dishwasher door rotatably mounted on the front side of the dishwasher body, and a groove formed on the front side of the dishwasher door. A support assembly is installed within the inner cavity of the groove. Wastewater generated during washing in the dishwasher body flows into a wastewater tank through a water pipe. The wastewater is collected in the wastewater tank, and during collection, oil stains in the wastewater are filtered through an oil filter. The filtered water remains at the bottom of the wastewater tank's inner cavity. When it is necessary to dry and heat the dishes inside the dishwasher body, a pump extracts the hot wastewater from the wastewater tank.

[0022] Please see Figures 1-5A dishwasher capable of recovering heat energy from wastewater includes a dishwasher body 1, a dishwasher door 2 rotatably mounted on the front side of the dishwasher body 1, a groove 3 formed on the front side of the dishwasher door 2, a support assembly 22 disposed within the inner cavity of the groove 3, a wastewater tank 9 bolted to the bottom of the dishwasher body 1, a water guide pipe 15 connected to the bottom of the dishwasher body 1, a heating box 16 bolted to the bottom of the dishwasher body 1, a baffle 18 bolted to the right side of the heating box 16, and an installation groove 13 formed on the rear side of the dishwasher body 1. The wastewater tank 9 is equipped with a first heat pipe 17 and a pump body 21 is bolted to the rear side. A second heat pipe 19 is installed in the inner cavity of the heating box 16. The pump body 21's suction pipe is connected to the wastewater tank 9 through a pipe. The pump body 21's outlet pipe is connected to a three-way solenoid valve 20 through a pipe. The rear side of the three-way solenoid valve 20 is connected to the first heat pipe 17 through a pipe. The rear side of the wastewater tank 9 is connected to the first heat pipe 17 through a pipe. The left side of the three-way solenoid valve 20 is connected to the second heat pipe 19 through a pipe. The right side of the second heat pipe 19 is connected to the wastewater tank 9 through a pipe.

[0023] Please see Figure 1 and Figure 2 The support assembly 22 includes a rotating block 4. The inner cavity of the groove 3 is rotatably connected to the rotating block 4. A storage tube 5 is installed at the bottom of the rotating block 4. A threaded sleeve 6 is rotatably connected to the bottom of the storage tube 5. A threaded rod 7 is provided through the bottom of the threaded sleeve 6. By setting the rotating block 4, the storage tube 5, the threaded sleeve 6 and the threaded rod 7, it is convenient to support the dishwasher door 2 when it is opened, and it is convenient to keep the dishwasher door 2 stable. The surface of the threaded rod 7 is threadedly connected to the threaded sleeve 6. A reinforcing rod 8 is welded to the opposite side of the storage tube 5.

[0024] Please see Figure 1 The bottom of the dishwasher body 1 is connected to a support leg 12 by bolts. By setting the support leg 12, the dishwasher body 1 can be supported and kept stable. The bottom of the support leg 12 is connected to an anti-slip plate by bolts. By setting the anti-slip plate, the friction between the support leg 12 and the ground can be increased and the support leg 12 can be kept stable.

[0025] Please see Figure 1 and Figure 4 The inner cavity of the wastewater tank 9 is connected to an oil filter screen 11 by bolts. By setting the oil filter screen 11, it can filter oil and facilitate the removal of oil stains from the wastewater, thus facilitating the treatment of wastewater. The front side of the dishwasher door 2 is provided with a pull groove, which facilitates the pulling of the dishwasher door 2 and makes it easy to open and close the dishwasher door 2.

[0026] Please see Figure 1The front side of the wastewater tank 9 is connected to a sealing plate 10 by bolts. By setting the sealing plate 10, the wastewater tank 9 can be sealed, which can effectively prevent wastewater from leaking out of the wastewater tank 9. The right side of the wastewater tank 9 is connected to a sewage pipe.

[0027] Please see Figure 1 and Figure 5 A water inlet pipe is connected to the top of the rear side of the heating box 16, and a drain pipe is connected to the bottom of the rear side of the heating box 16. By setting up the water inlet pipe and the drain pipe, it is easy to replace the water in the heating box 16 and to heat more water in the heating box 16.

[0028] Please see Figure 1 and Figure 3 A protective plate 14 is bolted to the rear side of the dishwasher body 1. By setting the protective plate 14, the mounting groove 13 can be sealed, the first heat conduction pipe 17 in the mounting groove 13 can be protected, and the first heat conduction pipe 17 can be effectively prevented from being damaged. The front side of the first heat conduction pipe 17 is in contact with the front side of the inner cavity of the groove 3.

[0029] In use, the device is controlled by an external controller. Wastewater generated during washing in the dishwasher body 1 flows into the wastewater tank 9 through the water pipe 15. The wastewater is collected in the wastewater tank 9. During the collection process, oil stains in the wastewater are filtered through the oil filter screen 11. The filtered water remains at the bottom of the inner cavity of the wastewater tank 9. The drain pipe is connected to an external valve, and the water pipe is connected to the water inlet pipe and the drain pipe. When it is necessary to dry and heat the dishes in the dishwasher body 1, the hot wastewater in the wastewater tank 9 is drawn out by the pump body 21. Then, the outlet pipe of the pump body 21 is connected to the first heat conduction pipe 17 through the three-way solenoid valve 20, and the hot wastewater is injected into the first heat conduction pipe 17 through the pump body 21. The dishwasher body 1 is heated and dried by hot water in the first heat pipe 17. When it is necessary to heat the clean water, the water outlet pipe of the pump body 21 is connected to the second heat pipe 19 through the three-way solenoid valve 20. The hot wastewater in the second heat pipe 19 heats the water in the heating box 16, thereby recovering the heat in the wastewater. When the dishwasher door 2 is opened, the threaded sleeve 6 is rotated to drive the threaded rod 7 to move up and down, and the extension length of the threaded rod 7 is adjusted. After the dishwasher door 2 is fully opened, the bottom of the threaded rod 7 contacts the ground. The dishwasher door 2 is supported by the rotating block 4, the storage cylinder 5, the threaded sleeve 6 and the threaded rod 7, which makes it easy for the dishwasher door 2 to remain stable.

[0030] In summary, this dishwasher capable of recovering heat energy from wastewater solves the problem that, through the baffle 18, the second heat pipe 19, the three-way solenoid valve 20, the pump body 21, and the support assembly 22, the device can only collect wastewater during use. However, since the dishwasher usually uses hot water for washing, it cannot recover and reuse the heat from the wastewater, resulting in resource waste and inconvenience for users.
