Fig. 1 is a schematic view of a heat recovery energy-saving device of a dishwasher according to a preferred embodiment of the present invention.
Detailed Description
The technical contents of the preferred embodiments of the present invention will be more clearly understood and appreciated by referring to the drawings attached to the specification. The present invention may be embodied in many different forms of embodiments, and the scope of the invention is not limited to the embodiments described herein.
In the drawings, structurally identical elements are represented by like reference numerals, and structurally or functionally similar elements are represented by like reference numerals throughout the several views. The size and thickness of each component shown in the drawings are arbitrarily illustrated, and the present invention is not limited to the size and thickness of each component. The thickness of the components may be exaggerated where appropriate in the figures to improve clarity.
As used herein, "above" refers to a location close to the steam heat recovery body, and "below" refers to a location far from the steam heat recovery body.
As shown in fig. 1, the heat recovery energy saving device of the dishwasher includes a temperature increasing device 1, a steam heat recovery body 2, a waste water heat recovery body 3, a first connection pipe 4 and a second connection pipe 5. The waste water heat recovery main body 3 comprises a waste hot water storage tank and a cold water preheating pipe. The waste hot water storage tank is provided with a waste hot water inlet, a cold water inlet, a waste hot water outlet and a preheated water outlet. The waste hot water inlet is positioned above the waste hot water storage tank, and the waste hot water outlet is positioned below the waste hot water storage tank. A water inlet valve is arranged at the waste hot water inlet, and the inlet of the waste hot water is controlled by screwing the water inlet valve. The waste hot water inlet is connected with a waste water outlet of the dish-washing machine, and the washed waste water enters the waste hot water storage tank through the waste hot water inlet. And a water outlet valve is arranged at the waste hot water outlet, and waste hot water is discharged by screwing the water outlet valve. The waste hot water outlet is connected with the sewage pipe, and the waste hot water after heat recovery is discharged to the sewage pipe through the waste hot water outlet. The cold water inlet is positioned at the first side of the waste hot water storage tank and communicated with the cold water storage device. The preheating water outlet is positioned at the second side of the waste hot water storage tank and is connected with the steam heat recovery main body 2 through a first connecting pipe 4. Cold water from the cold water reservoir enters the cold water preheating pipe in the waste water heat recovery main body 3 through the cold water inlet. The cold water preheating pipe is positioned inside the waste hot water storage tank, and the waste hot water storage tank stores a large amount of waste hot water. The cold water preheating pipe is immersed in the waste hot water and penetrates through the waste hot water storage tank. The loops of the cold water preheating pipes are arranged in a parallel mode, so that the contact area between the cold water preheating pipes and the waste hot water is increased, and the heat energy of the waste hot water is absorbed when cold water flows through the cold water preheating pipes. The first connection pipe 4 connects the waste water heat-recovery main body 3 and the steam heat-recovery main body 2. The steam heat recovery body 2 is located above the temperature booster 1 and the waste water heat recovery body 3, i.e., at the top of the dishwasher. The heat exchange pipe loop is arranged in a parallel mode, the contact area between the heat exchange pipe loop and the waste steam is increased, when preheated water flows through the heat exchange pipe, the heat energy of the waste steam is absorbed, and the temperature is further increased. The second connection pipe 5 connects the steam heat recovery main body 2 and the temperature increasing unit 1. The temperature increasing device 1 is arranged in a dish washing machine. The temperature of the cold water passing through the waste water heat recovery main body 3 and the steam heat recovery main body 2 is remarkably increased due to the absorption of a large amount of heat energy, and the temperature of the cold water reaching the temperature rising device is 25-30 ℃ higher than the temperature of the cold water directly entering the temperature rising device.
When the dishwasher is in use or after use, the water inlet valve is opened, so that the waste hot water enters the waste hot water storage tank of the waste water heat recovery main body 3 and exchanges heat with the cold water in the cold water preheating pipe. The cold water warmed up in this process is called preheated water. The preheated water enters the first connecting pipe 4 and is pumped into the steam heat recovery main body 2 under the action of the water pump. The preheated water is heat-exchanged with the hot steam through the steam heat recovery main body 2 to be further heated. The preheated water obtained at this stage is further warmed up and called hot water. Hot water enters the temperature rising device along with the second connecting pipe 5 under the action of gravity, and can reach preset high temperature only by carrying out partial temperature rising, and dishes are washed continuously.
The cold water may originate from a cold water storage device, which may be a closed or open circulation tank.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the teachings of this invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
