Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and more specifically, to a dishwasher with a water purification and circulation function. Background Technology

[0002] Dishwashers have demanding operating environments, requiring specific water inlet and outlet locations. For example, they rely on the consumer's home's tap water inlet for water intake and share a drain outlet for drainage. If a consumer didn't plan to install a dishwasher before kitchen renovation and didn't pre-install a water inlet, the dishwasher will be unusable later. Alternatively, a temporary T-junction pipe can be added, but this exposes the inlet pipe, affecting the aesthetics of the renovation. Another option is to use an external container for water intake and drainage, but this requires filling with clean water each time and emptying the wastewater container afterward, potentially causing contamination or dirt in other areas, making it very inconvenient.

[0003] Therefore, a new solution is needed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dishwasher with a water purification and circulation function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dishwasher with water purification and circulation function includes a dishwasher body and a purification base station connected to the dishwasher body. The purification base station includes a clean water tank, a distillation mechanism, and a condensation mechanism. The drain outlet of the clean water tank is connected to the water inlet of the dishwasher body, and the clean water tank is used to supply water to the dishwasher body. The water inlet of the distillation mechanism is connected to the drain outlet of the dishwasher body, and heats and vaporizes the wastewater after the dishwasher body is used to form water vapor. The water vapor is transferred to the condensation mechanism, and the drain outlet of the condensation mechanism is connected to the water inlet of the clean water tank, where the water vapor is condensed to form clean water, which is then transferred to the clean water tank.

[0007] Furthermore, the distillation mechanism includes a wastewater tank, in which a heating pump and a residue box are installed. The inlet of the wastewater tank is connected to the drain outlet of the dishwasher body, and the vent of the wastewater tank is connected to the steam inlet of the condensation mechanism. The heating pump is used to heat and vaporize the wastewater in the wastewater tank to form water vapor, and the residue box is used to collect residue from the wastewater.

[0008] Furthermore, a filter screen is installed at the inlet of the wastewater tank.

[0009] Furthermore, the exhaust port of the wastewater tank is connected to a first copper pipe, which is also connected to the steam inlet of the condensation mechanism.

[0010] Furthermore, the condensation mechanism includes a second copper tube, a compressor, and a heat sink. The two ends of the second copper tube are respectively connected to a distillation mechanism and a purified water tank. The second copper tube is in contact with the heat sink. The compressor delivers refrigerant to the heat sink, and the heat sink condenses the water vapor in the second copper tube to form purified water.

[0011] Furthermore, the purification base station also includes a duct and an exhaust fan. One end of the duct is used to connect to the purified water tank, and the other end of the duct is connected to the outside air. The exhaust fan is used to draw outside air into the duct, and the condensation mechanism condenses the moisture in the air inside the duct to replenish the purified water tank.

[0012] The beneficial effects of this utility model are:

[0013] 1. In this utility model, by setting up a purification base station, the dishwasher body and the purification base station are combined to form a closed loop. The wastewater after the dishwasher body is used is heated and vaporized by the distillation mechanism to form water vapor. The water vapor is condensed by the condensation mechanism to form clean water. The clean water is used to clean the dishwasher body. This cycle is repeated to achieve the effect that the dishwasher can be used permanently after adding water once.

[0014] 2. In this utility model, by setting up an air duct and an exhaust fan, the exhaust fan draws outside air into the air duct, and the condensation mechanism condenses the moisture in the air in the air duct to replenish the water tank, so that the dishwasher has sufficient water supply.

Detailed Implementation

[0018] 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 protection scope of the present utility model.

[0019] Example: A dishwasher with water purification and circulation function, such as Figure 1 As shown, the system includes a dishwasher body 1 and a purification base station 2 connected to the dishwasher body 1. The purification base station 2 is used to heat and vaporize the wastewater after the dishwasher body 1 is used to form water vapor, and then condense the water vapor to form clean water. The clean water is used to clean the dishwasher body 1. This cycle is repeated to achieve the effect that the dishwasher can be used permanently after adding water once.

[0020] Specifically, the purification base station 2 includes a clean water tank 21, a distillation mechanism 22, and a condensation mechanism 23. The drain outlet of the clean water tank 21 is connected to the water inlet of the dishwasher body 1, and the clean water tank 21 is used to supply water to the dishwasher body 1. The water inlet of the distillation mechanism 22 is connected to the drain outlet of the dishwasher body 1, and heats and vaporizes the wastewater after the dishwasher body 1 is used to form water vapor. The water vapor is transferred to the condensation mechanism 23, and the drain outlet of the condensation mechanism 23 is connected to the water inlet of the clean water tank 21, and the water vapor is cooled and condensed to form clean water. The clean water is transferred to the clean water tank 21 and used for cleaning the dishwasher body 1. This cycle repeats continuously.

[0021] Furthermore, the distillation mechanism 22 includes a wastewater tank 221, which stores wastewater after the dishwasher body 1 has been used. A heating pump 222 and a residue box 223 are installed inside the wastewater tank 221. The wastewater tank 221 has a water inlet and a steam outlet. The water inlet of the wastewater tank 221 is connected to the drain outlet of the dishwasher body 1, and the steam outlet of the wastewater tank 221 is connected to the steam inlet of the condensation mechanism 23. The heating pump 222 heats the wastewater in the wastewater tank 221 until it is completely vaporized to form water vapor. The water vapor enters the condensation mechanism 23 through the first copper pipe 225. The residue box 223 collects residue from the wastewater. The heating pump 222 and the residue box 223 can be installed at the bottom of the wastewater tank 221 or at any other location within the wastewater tank 221 as needed, but it must be ensured that the heating pump 222 can heat and vaporize the wastewater, and that the residue box 223 can collect the residue remaining after the wastewater has been heated. The residue box 223 is a pull-out residue box 223, which makes it easy to clean the residue inside the residue box 223.

[0022] Preferably, a filter screen 224 is installed at the inlet of the wastewater tank 221. The filter screen 224 filters the wastewater after the dishwasher is used, removing water-insoluble and large-volume residues, while smaller, water-insoluble residues pass through the mesh of the filter screen 224 and enter the wastewater tank 221 with the wastewater. The filter screen 224 can be a fine filter screen 224 to improve the filtration effect. At the same time, the filter screen 224 is installed in a detachable manner at the inlet of the wastewater tank 221 to facilitate cleaning of the filter screen 224 and prevent excessive residue from clogging the mesh of the filter screen 224, thereby affecting the discharge of wastewater from the dishwasher body 1.

[0023] Preferably, the exhaust port of the sewage tank 221 is connected to a first copper pipe 225, and the steam inlet of the condensing mechanism 23 is connected through the first copper pipe 225. The first copper pipe 225 uses its thermal conductivity to initially cool the water vapor formed by heating and vaporizing the sewage, so as to reduce the energy consumption of the condensing mechanism 23 and the loss of refrigerant.

[0024] Furthermore, the condensing mechanism 23 adopts the condensing principle of the existing compressor 232, including a second copper pipe 231, a compressor 232, and a heat sink 233. One end of the second copper pipe 231 is connected to the first copper pipe 225, and the other end of the second copper pipe 231 is connected to the clean water tank 21. The second copper pipe 231 and the heat sink 233 are in contact. In use, the compressor 232 delivers refrigerant to the heat sink 233, and the heat sink 233 condenses the water vapor in the second copper pipe 231 to form clean water. The clean water is transferred to the clean water tank 21 for use by the dishwasher body 1 for cleaning.

[0025] When using a dishwasher, such as Figure 2 As shown, water is added to the clean water tank 21 to at least meet the water intake of the dishwasher body 1 for a single use. The drain outlet of the clean water tank 21 and the inlet of the wastewater tank 221 are connected to the inlet and drain outlet of the dishwasher body 1, respectively, so that the water in the clean water tank 21 can be transferred into the dishwasher body 1, and the wastewater after the dishwasher body 1 is used can be transferred into the wastewater tank 221. The filter screen 224 filters out the residue that is insoluble in water and has a large volume. The filtered wastewater is transferred into the wastewater tank 221. The heating pump 222 heats the wastewater in the wastewater tank 221 until it is completely vaporized to form water vapor. The water vapor enters the second copper pipe 231 through the first copper pipe 225. The residue remaining after the wastewater is heated is left in the residue box 223. The compressor 232 delivers refrigerant to the heat sink 233. The heat sink 233 condenses the water vapor in the second copper pipe 231 to form clean water. The clean water is transferred into the clean water tank 21 for the dishwasher body 1 to be used for cleaning again. During the above-mentioned use, the dishwasher body 1 and the purification base station 2 combine to form a closed loop. The wastewater after the dishwasher body 1 is used is heated and vaporized to form water vapor. The water vapor is condensed to form clean water, which is then used to clean the dishwasher body 1. This cycle repeats continuously.

[0026] The aforementioned purification base station also includes a duct 24 and an exhaust fan 25. The duct 24 and exhaust fan 25 are used to replenish the water tank 21, compensating for the water lost during distillation. Specifically, one end of the duct 24 is connected to the water tank 21, and the other end is connected to the outside air. The exhaust fan 25 draws outside air into the duct 24, and the condensation mechanism 23 condenses the moisture in the air inside the duct 24 to replenish the water tank 21, achieving the effect of the dishwasher being usable permanently after a single water refill.

[0027] Preferably, one end of the air duct 24 can be connected to a third copper pipe, and the third copper pipe is connected to the water tank 21. The third copper pipe abuts against the heat sink 233 in the condensation mechanism 23. The heat sink 233 condenses the moisture in the air inside the third copper pipe to form water. The water is transferred to the water tank 21 to replenish the water lost during the distillation process, so that the dishwasher has sufficient water.

[0028] Alternatively, one end of the duct 24 can be connected to the second copper pipe 231, sharing the same second copper pipe 231 with the water vapor generated from the heating and vaporization of wastewater. Water in the air within the second copper pipe 231 is condensed by heat sinks 233 to form water, which is then transferred to the clean water tank 21 to replenish the water lost during distillation. With this design, the condensation of air into water and the heating and vaporization of wastewater are carried out separately. A one-way valve is installed on the second copper pipe 231 to prevent air from entering the wastewater tank 221. Simultaneously, when the exhaust fan 25 draws in outside air, the air must be filtered to prevent the introduction of impurities.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
