Cleaning device and heat recovery system thereof

Abstract

A cleaning device used for cleaning tableware and provided with a waste heat recycling device comprises a water input unit used for inputting water at a first temperature, a heating unit used for heating water from the water input unit into hot water at a third temperature, a water output unit used for outputting the hot water for cleaning work, and the heat recycling device which is communicated with the hot water and/or steam fluid generated from the hot water so as to receive, store, transfer and/or adjust waste heat of the hot water and/or the steam. At least part of the water input unit is connected with the heat recycling device so as to receive the waste heat from the heat recycling device and/or the hot water and/or the steam, and the water in the water input unit is adjusted to a second temperature before being heated by the heating unit. According to the technical scheme, the cleaning device is simple in structure and capable of saving energy, energy consumption is greatly reduced, the heating waiting time is greatly shortened, a heater with low power can be selected and used, and thus the use cost is reduced.

Description

technical field [0001] The present invention relates to a cleaning device, more particularly to a cleaning device with a heat recovery device / system. Background technique [0002] There are various cleaning devices currently on the market, such as dishwashing machines, which generally use heaters to heat incoming water at room temperature (temperature about 25°C) to 70-95°C to rinse and / or rinse the dishes. Due to the long heating time and high heating cost, there is a long-term need in the art for an improved dishwasher that can reduce heating time and cost. [0003] specific reference Figure 1-2 , showing a prior art sealed two-stage cleaning machine / equipment 1 for cleaning tableware 50 (such as bowls, plates, plates, chopsticks, spoons, knives, forks and / or cups, etc.), which includes : a casing 60 generally in a substantially sealed state with an input end and an output end; an automatic conveying mechanism 40 having an input end 401 and an output end 402, including a...

AI Technical Summary

Problems solved by technology

Although this type of dishwasher can utilize the thermal energy of waste water to some extent, it requires additional space to store and transfer waste water and additional time for preheating, so its overall cost, operating time / efficiency and performance Limited advantage
