Description

  The present invention is a dishwasher waste that improves the efficiency of use by improving the efficiency of use of the washer by reusing the waste heat energy contained in the waste wash water that is discarded after the end of use in the automatic dishwasher. The present invention relates to a thermal energy reuse device.

  Usually, if the water temperature of the raw cleaning water (rinse water) used in the dishwasher cannot be maintained at a temperature of about 82 ° C. or higher, good cleaning power and reliable sterilization effect cannot be obtained.

  Therefore, the washing raw water (rinse water) supplied to the automatic dishwasher is directly heated to 82 ° C or higher of an appropriate washing water temperature by a gas heating water heater or an electric heating water heater and supplied to the automatic dishwashing machine. I use it.

To explain further, the dishwasher that has been used in the past is a low-temperature washing raw water (rinsing water) that is carried in from a raw water pipe in order to heat the washing raw water (rinsing water) flowing into the washing machine to an appropriate temperature. ) Is introduced into a gas or electric heating / hot water apparatus, heated to an appropriate temperature by the heating / water heater, and then supplied to the dishwasher for use.

  In the conventional heating raw water (rinse water) heating method, since the raw raw water (rinse water) at about 8 ° C. must be rapidly raised to 82 ° C. or more, excessive heating energy is consumed, and gas or electric heating hot water is used. The workability is reduced due to the time delay it takes for the raw cleaning water (rinse water) to reach the proper temperature level in the vessel, and only when the proper temperature is maintained, the good cleaning power and the best sterilization effect are maximized. The current situation is that there are various problems due to the characteristics of automatic dishwashers.

  Therefore, the present invention has been devised to solve the above-mentioned conventional problems, and waste heat energy for dishwashers that reuses waste heat energy contained in waste wash water that has been used. The purpose is to provide a recycling device.

It flows out to the waste water exit 47.

  Furthermore, the raw water inlet 42 is connected to one end of the outer pipe of the double corrugated pipe 44 through the outer pipe of the double pipe nipple 48b, and the low temperature washing raw water (rinse water) flowing from the raw water inlet 42 is: The waste water heat is absorbed while flowing back along the raw water endothermic pipe B which is the outer pipe of the double corrugated pipe 44, and the low temperature raw water at 8 ° C is preheated to the heated hot water at about 40 ° C, and the washing raw water (rinse water) is The primary heating water heater 60 led to the endothermic water outlet 43b connected to the other end of the outer pipe of the double corrugated pipe 44 via the outer pipe of the double pipe nipple 48b and connected to the endothermic water outlet 43b. Is heated to high temperature water of about 60 ° C., led to the heated water inlet 43a, and flowed into the secondary heating water heater 70 installed in the lower part of the dishwasher, where the washing water has an appropriate water temperature. This is heated to 82 ° C or higher and then supplied to the cleaning room. It will serve as the rinse water for the next purpose.

  Therefore, the waste washing water discarded for use is repeatedly recycled by the reuse system, and the amount of heat it has naturally, that is, the heat of about 40 ° C., which is two-thirds of 60 ° C., is supplied to the raw water endothermic tube B. Conducting waste heat reuse system for dishwashers continuously by conducting to low-flow raw wash water (rinse water) that is newly introduced.

  (Example of reuse device for continuous use of washing machine)

  As shown in the table above, economic loss due to excessive waste of time and energy until low temperature raw water of 8 ° C enters and reaches the appropriate water temperature of 82 ° C via the primary heater and the secondary heater. Many problems have occurred, such as reduced workability due to delay in heating time, reduced dishwashing power due to non-uniform water temperature deviation, and reduced sterilization effect. Was able to be solved at once.

  In particular, the waste heat energy recycling system of the present invention can be easily mounted on the lower rear side of the dishwasher because the apparatus itself has a very simple structure.
