Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher using an apparatus for recycling waste heat generated from a process of heating rinsing water and washing water, which is the source of cleaning water, and washing the waste water of the wastewater discharged out of the dishwasher. After the primary heated raw water (rinsing water) is introduced into the waste gas heat saving booster (7) built into the lower part of the washing machine by means of the gas instantaneous water heater (5) installed hereafter (hereinafter referred to as 'primary gas hot water heater'). The secondary electric hot water heater (7-1-3) is configured to be used as washing and rinsing water by pumping this water when the proper temperature is reached after the second heating. Since the temperature of the rinsing water firstly heated by the primary gas warm water heater 5 is very low as the rinsing hot water, it is heated by the secondary electric warm water heater 7-1-3. As a result, the secondary electric hot water heater 7-1-3 is heated with electric energy. This method is inefficient and inefficient, which consumes excessive electric energy and requires a lot of time, and the more the dishwasher is used, the lower the temperature of the rinsing water, leading to poor washing and rinsing power. The present invention aims to improve such economic loss and inefficient operation, and to realize the improvement, in the primary gas hot water heater (5), the waste heat energy inherent in the waste gas, which has played its role, is washed and The waste heat energy inherent in the rinsing waste water after recycling and rinsing is also recycled to realize a more powerful, economical and innovative ultra-low-power energy washing system, preventing customers' satisfaction and economical energy waste, as well as preventing national economic losses.

The present invention relates to a dishwasher using a waste heat saving device that utilizes waste heat in order to heat washing water (rinsing water) introduced into the washing machine to an appropriate temperature for washing and rinsing in an automatic dishwasher. In detail, energy is saved by recycling waste heat in waste gas in the apparatus for recycling wastewater heat energy with washing wastewater discharged to the outside of the washer and the primary gas hot water heater (5) used to supply hot water to the dishwasher. Of course, the present invention relates to an ultra-low power type washer that can prevent the rinsing water temperature and the washing power from being lowered due to the continuous use of the dishwasher.

In general, the water temperature of the rinsing water used in the automatic dishwasher is maintained only at a temperature of 82 ℃ or more, while the strong washing power and a reliable rinsing, sterilization and drying effect can be obtained, while the raw water of the conventional dishwasher (rinse Water) heating method is generally about 10 ℃ rinsing water (rinse water) when the primary heating the primary gas hot water heater (5) is about 40 ℃ rinsing water, this rinse water is again converted into electrical energy The secondary electric hot water heater (7-1-3) used is heated and used to raise the temperature of the rinsing water to 82 ° C or higher. In many cases, the dishwasher is continuously used. However, in order to increase the rinsing water to an appropriate temperature, excessive electric energy is required for an instantaneous temperature rise. In addition, the prior art, there is a Republic of Korea Patent Publication No. 10-2004-0073230 'waste heat energy recycling device for dishwasher'. This device is characterized by a double corrugated pipe. Looking at the characteristics of the waste heat energy recycling device using the double fold pipe, the rinsing water after the rinsing flows into the wash tub and flows into the drain corrugated pipe inside the double corrugated pipe, the waste heat energy recycling device, through the washing waste drain inlet at the top of the wash tub. After passing through the letter 'd', it slowly flows down to the bottom drain of the washer to maximize thermal efficiency. In this method, the drainage is not desired in the continuous use, so the washing water rises up to the washing nozzle, which lowers the washing power.The drainage inlet of the washing tub is located at the top of the washing tub. On the other hand, it will discharge the rinsing water with low pollution and reduce the washing power and the rinsing power.In contrast with the high waste heat energy of washing waste water, it is not expected to recover high heat energy. Not only the economic burden, but also the constant and excessive gas and electricity costs greatly reduce the great benefits of dishwashers, which reduce the sanitary safety and labor costs of the kitchen. Furthermore, no one can deny that they are wasting a lot of energy nationally.

The present invention was created to solve the above problems, by maximizing and recycling the energy efficiency of the various means for heating up the washing water (rinse water), that is, the raw water (rinse water) to be supplied to the dishwasher Waste gas heat energy of the primary gas hot water heater (5) operating to heat and the washing and rinsing heat discharged to the outside of the washing machine after the washing and rinsing work are recycled. For this purpose, the primary gas hot water is used. Tap water flowing into the heater (5), that is, washing raw water (rinsing water) is heated, and the rinsing water heat and waste tub of the waste gas heat saving booster (7) by the waste gas thermal energy of the primary gas water heater (5) It is to provide an ultra-low power dishwasher with 30% of the maximum power consumption and less than 10% of the power consumption compared to the conventional dishwasher by heating the washing water.

The present invention as described above is installed on the front of the waste gas heat saving booster (7) of the primary gas hot water heater (5) installed outside to supply the raw water (rinse water) of the dishwasher, 1 The flue gas induced by the waste gas of the hot water heater (5) is passed through the waste gas heat saving booster (7) inside the washer and passed through the washer (11) to be discharged, and the heat energy of the washing waste water is installed on the side of the washer. By passing through the waste water heat saving chamber 1, the primary gas hot water is conducted to the washing raw water (rinsing water) flowing into the heater 5 with high efficiency as a technical problem.

The dishwasher using the two waste heat saving apparatuses according to the present invention has the heat energy of the waste gas of the primary gas hot water heater (5) used to heat the raw water and the washing waste water discharged out of the dishwasher after the washing. It is characterized by using the thermal energy.

In order to achieve the above object, the present invention is configured to be built in a dish storage basket (rack) that can hold a variety of sorting, such as, the interior is configured in the form of a space and the spray nozzle is installed inside On the lower side, the waste gas heat saving booster after the primary heating of the water supply source of the dishwasher having a main body having various washing means, that is, the washing water (rinse water) with the primary gas temperature water heater (5) (7). In the dishwasher which is used as the raw water for washing after storing in the rinsing water tank and heating it with a secondary electric hot water heater (7-1-3) to raise it to an appropriate temperature and then pumping it with a washing pump.

The endothermic wrinkle tube in the form of a continuous 'S' in which the wastewater heat saving chamber 1 is mounted on the lower side of the dishwasher and the washing water is supplied to the chamber source inlet port 1-3 of the wastewater heat saving chamber 1. 1-5) is connected to the connection portion, and the waste gas heat saving booster (7) in front of the waste gas heat saving booster (7), which is configured in connection with the washing tank 11, is installed in connection with the waste water heat saving chamber (1), The lower portion of the inner side of the washing tank 11 is connected to the wastewater heat saving chamber 1, and the wastewater heat saving chamber 1 is connected to the waste water draining chamber 1 again. Typically, in the automatic dishwasher, the water temperature of the rinsing water used is only maintained at a temperature of 82 ℃ or more, it is possible to obtain a strong washing power and a reliable rinsing, sterilization and drying effect. In the conventional method of heating the rinsing water of the dishwasher, when a washing source (rinsing water) of about 10 ° C. is first heated through the primary gas hot water heater 5, the rinsing water is about 40 ° C., and this washing is performed. The raw water (rinse water) is heated again with a secondary electric hot water heater (7-1-3) using electric energy and used to raise the temperature of the washing raw water (rinse water) to 82 ° C or higher. In many cases, the dishwasher is continuously used. However, in order to raise the raw water (rinse water) to an appropriate temperature, excessive electric energy is required for the instantaneous temperature rise as well as for many hours. Ultra-low power dishwashers are made by using waste heat saving devices.

 Explaining the configuration and operation of the respective devices, the wastewater heat saving of the wastewater heat saving chamber (1-3) in which the washing water is supplied to the upper right side of the waste water heat saving chamber (1) of the dishwasher The chamber waste outlet 1-2, which is an outlet discharged out of the chamber 1, is connected, and the lower left side of the waste water heat saving chamber 1 is a passage through which the washing water is drained out of the waste water heat saving chamber 1, Chamber waste inlet (1-1), which is connected to the gas hot water heater (5), and the suction wastewater which is sucked into the waste water heat saving chamber (1), which is inside the washing tub (11). ) Is connected to the wastewater heat saving chamber (1), and the endothermic corrugated pipe (1-5) connected to the chamber source inlet (1-3) has a continuous 'S' shape from the top to the bottom of the wastewater path plate (1--1). 6) are routed in order to connect and connect with the chamber member outlet (1-4). The wastewater path plate (1-6) is sequentially moved from the lower part of the ice chamber (1) to the upper part. (5-1) enters the primary gas hot water heater (5) through a pipe connected to the heating and discharged to the heater outlet (5-1) through the water supply solenoid valve 31, the booster water supply port (7-1) -1) The water is supplied to the upper front of the waste gas heat saving booster (7). At this time, the waste gas generated after burning the gas in order to heat the washing water in the primary gas hot water heater (5) has a lot of heat energy communication tube, that is, booster waste gas communication (7-5), washing waste gas communication (7- 3) passing the washing raw water of the waste gas heat saving booster (7) is heated, and when the raw water is full in the waste gas heat saving booster (7), the washing water supply pipe (7-4-1) to the washing tank (11) When the water is supplied, the raw water from the washing water supply pipe (7-4-1) is dropped into the washing waste gas communication (7-3) is heated again. When the water level of the washing tank 11 is full, the air rod 10-1 of the water drain check valve 10 is lifted by buoyancy, and the configuration of the water drain check valve is air rod 10-1 and the support part. The connecting portion 10-2 for connecting the 10-3 is coupled to the fixing portion 10-4, and the check portion 10-2 is fixed to the connecting portion 10-2 by being configured to be connected. , Washing tub side fluid inlet and outlet (10-9) and check ball housing (10-8), piping connection side fluid inlet and outlet (10-6) is configured, the level of the washing tank (11) when the water level of the check ball (10- 10) This check rod 10-5 is not interfered with. Therefore, after the rinsing after washing, the raw water (rinsing water) enters the washing container 11, and the washing water of the washing container 11 is located at the position of the chamber waste outlet 1-2 located above the waste water heat saving chamber 1. The water level becomes higher, and the force of the generated potential energy is opened by moving the check ball 10-10 of the water drain check valve 10 in the B direction, and the water level of the washing tank 11 and the waste water heat saving chamber (1). ) Until the water level is equal. Of course, the heat energy of the washing wastewater accumulated in the wastewater heat saving chamber 1 is conducted to all of the raw water in the endothermic wrinkle pipe 1-5 and overflows to the chamber waste outlet 1-2 so that it flows to the washing tub drain 21. When washing, the water level in the washing tank 11 is temporarily lowered than the wastewater heat saving chamber 1 by pumping the washing pump, and the washing wastewater in the wastewater heat saving chamber 1 having low potential energy, which has lost heat energy, is washed again. When it is possible to move to the tub 11, when it is moved and combined with the washing water of the washing tub 11, the temperature of the washing water is lowered, a phenomenon that the thermal efficiency is lowered. In order to prevent this, the drainage check valve 10 check ball (10-10) that the washing waste water of the waste water heat saving chamber (1) moves in the C direction, that is, the washing tub 11 direction check ball packing portion 10 -12), making it impossible to move, thereby increasing the thermal efficiency. In addition, when the wash water drainage of the washing tank 11, the air rod (10-1) of the water drain check valve 10 is lowered without buoyancy, so the check ball mill (10-5) check ball (10-10) It is pushed to drain all the contaminated washing wastewater in the wastewater heat saving chamber 1, so that the waste heat saving system can be implemented with the cleanliness and high energy efficiency of the wastewater heat saving chamber 1.

That is, the washing raw water (rinsing water), which is about 10 ° C., is first heated by the waste water heat saving chamber 1 and rises to about 40 ° C. or more, and the washing raw water thus raised is 2 of the primary gas hot water heater 5. It is raised again to about 70 ℃ by the secondary heating, the washing raw water (rinsing water) stored in the waste gas heat saving booster (7) is in communication with the waste gas having the high thermal energy of the primary gas hot water heater (5) penetrates again, The high temperature wash water (rinse water) of about 82 ° C. or more suitable for washing water (rinsing water) is heated by the booster waste gas communication (7-5) to the secondary electric hot water heater (7-1-3). It can be realized by recycling waste heat without consuming heating energy. Thus, even if the capacity of the secondary electric hot water heater (7-1-3), which is a secondary heating source, is higher than 3KW / h, the water temperature of the raw water for washing (rinsing water) is 60 ° C or lower in continuous use. By using two waste heat saving devices, the second heating source provides a dishwasher that can supply the raw water (rinse water) to a high temperature of 82 ° C or higher without the secondary electric hot water heater (7-1-3). You can do it. In the foregoing detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims that follow, but also by the equivalents thereof.

As described above, according to the present invention, the waste heat saving apparatus using waste heat discarded in the air and into the sewage system has 90% of the high two waste heat energy inherent in the waste gas heat and the washing waste water from the primary gas hot water heater (5). By recovering the abnormalities and conducting and heating the washing raw water (rinsing water), the electrical energy of the secondary wastewater for heating the washing raw water (rinsing water) is not required even with these two waste heat energy alone. That is, the capacity of the secondary electric hot water heater (7-1-3) that requires excessive power can be reduced to about 0.8 kw / h, which can reduce the total maximum power consumption of the dishwasher to 0.8 kw / h. Of course, even if the primary gas hot water heater (5) is washed continuously, the temperature does not fall anymore, even when the dishwasher is continuously operated, even if the secondary electric hot water heater (7-1-3) does not operate the two waste heat saving The device can raise the temperature by more than 82 ℃, which is the proper temperature of the raw water (rinsing water), which saves energy, improves the work force and reduces the rinsing water by the simple installation of the ultra-low power type washer and the shortening of the heating time. By maintaining the temperature, it can be said to be a very useful invention that can maximize the rinsing power, sterilization power, drying, including washing power.
