Description

[Detailed explanation of the idea]

0001

[Industrial application field]

In this invention, dishes are placed in a washing tank and washed with washing liquid, and then This invention relates to a dishwasher that dries dishes.

0002

[Conventional technology]

Conventional dishwashers use cleaning liquid to wash dishes placed in a washing tank. After rinsing with water several times, perform a final rinse with hot water to raise the temperature inside the cleaning tank. The residual heat was used to dry the dishes.

0003 Also, when drying dishes, air is supplied from outside the washing tank and the air is heated with a heater. A fan is used to forcefully blow air onto the dishes in the washing tank, and this warm air dries the dishes. There was one that allowed the humid air to be exhausted after the air was drained.

0004

[Problem that the idea aims to solve]

If drying is performed using residual heat as described above, air circulation within the cleaning tank will be reduced. Because this process was not carried out, sufficient drying was not carried out. Also, if drying is performed using warm air generated by a heater or fan, high humidity may occur. The system kit There was a problem of damaging furniture such as chin. Odors and bacteria are generated from the remaining water and leftover food in the cleaning tank, so food It was not possible to store the container for a long time.

[0005] The dishwasher of this invention was designed in consideration of the above problems, and the dishwasher in the washing tank is The air is circulated through the drying path of the air circulation path to dehumidify the moisture in the air and dry the dishes. After drying is completed, ozone-containing air is circulated in the storage path of the air circulation path. The purpose is to deodorize and sterilize the inside of the cleaning tank using ozone and store tableware. It is.

[0006]

[Means to solve the problem]

In order to achieve the above objectives, the dishwasher of the present invention has the following features: Place the dishes in the washing tank, wash the dishes with the washing liquid, and then dry the dishes. In the dishwasher An ozone generator is installed to generate ozone to deodorize and sterilize the cleaning tank. The cleaning tank is provided with an intake port and an exhaust port, An air circulation path that communicates the intake port and the exhaust port to circulate the air in the cleaning tank. established, branching the air circulation path into a drying path and a storage path; A dehumidifier is installed in the drying path to cool the circulating air and remove moisture from the circulating air. , A catalyst that decomposes ozone is installed in the storage path, The circulating air passage is selectively cut into the drying passage and the storage passage in the air circulation passage. A switching valve is provided to change the

[0007]

[Effect]

In the dishwasher with the above configuration, after the dishes are washed with the washing liquid, air flows into the drying path. The air in the cleaning tank is circulated and the moisture in the air is removed by switching the switching valve so that the Use a dehumidifier to dehumidify and dry dishes. After the dishes are completely dried, the switching valve is turned on and the ozone generator generates ozone. This ozone is used to deodorize and sterilize the inside of the cleaning tank. Air containing excess ozone is circulated to the storage path, and this excess ozone is decomposed by a catalyst. The tableware is then collected and stored in a washing tank.

[0008]

【Example】

An embodiment of the dishwasher of the present invention will be described with reference to FIGS. 1 to 3. The dishwasher of the present invention has a washing liquid at the bottom of the washing tank 1 of the washing machine body (not shown). A water storage part 2 is provided to store water for rinsing, and a jet to discharge cleaning liquid into the cleaning tank 1 is provided. A discharge nozzle 3 is provided to discharge cleaning liquid from the discharge nozzle 3 into the water storage section 2. A second cleaning pump 4 is connected, and the cleaning pump 4 and the jet nozzle 3 are connected through a communication pipe 5. Connected. The cleaning liquid and rinsing water are heated at the bottom of the cleaning tank 1, and the water inside the cleaning tank 1 is heated during drying. A heater 6 is provided to heat the air, and ozone is supplied to the water storage section 2 of the cleaning tank 1 to remove ozone. An ozone generator 7 is provided to remove odors and sterilize the air.

[0009] The cleaning tank 1 is provided with an intake port 8 and an exhaust port 9, and the intake port 8 and the exhaust port 9 are provided. An air circulation path 10 is provided to communicate with the cleaning tank 1 to circulate the air in the cleaning tank 1. A circulation fan 11 is provided in the ring path 10. This air circulation path 10 is branched into a drying path 12 and a storage path 13. The hot air that evaporates the water adhering to the dishes is cooled, and the steam of this hot air is condensed and becomes water again. A cooling water injection nozzle 14 is installed to dehumidify the air, and a cleaning tank is installed in the storage path 13. A catalyst 15 is provided to decompose excess ozone after deodorizing and sterilizing the inside. A drying path switching valve 16 for opening and closing the drying path 12 is provided in the drying path 12, and The storage path 13 is provided with a storage path switching valve 17 that opens and closes the storage path 13. Opening/closing operation of road switching valve 16 and storage road switching valve 17 by valve drive unit (motor) 18 do. One of the drying path switching valve 16 and storage path switching valve 17 is open. When the other side is closed, only one side is open.

0010 To explain the operation of the dishwasher with the above configuration, the cleaning liquid in the water storage section 2 is pumped into the cleaning pump 4. Wash the dishes by discharging from the pumping jet nozzle 3, and after washing, drain the washing liquid. Rinse dishes with rinse water.

[0011] Next, in the drying process, the valve driving unit 18 opens the drying path switching valve 16 and the storage path switching valve 16 is opened. The switching valve 17 is closed. The air in the cleaning tank 1 is heated by the heater 6 and the air adheres to the dishes. Water is evaporated and the steam is circulated within the cleaning tank 1 by a circulation fan 11. this cycle The air is cooled by cooling water injected from the cooling water injection nozzle 14 of the air circulation path 10. The moisture in the circulating air is dehumidified and the dry air is exhausted into the cleaning tank 1 from the exhaust port 9. and dry dishes efficiently.

0012 After this drying process is completed, the valve drive unit 18 closes the drying path switching valve 16 and The switching valve 17 is opened. The ozone generator 7 generates ozone and removes the remaining water in the water storage section 2. The leftover food is deodorized and sterilized, and the air inside the cleaning tank 1 is transferred to the storage path 13 by the circulation fan 11. circulate through. Excess ozone contained in this circulating air is decomposed by catalyst 15. This prevents the effects on the human body and enables storage of tableware in the washing tank 1.

[0013]

[Effect of the idea]

Since the dishwasher of the present invention has the above-mentioned configuration, the humid air is removed from the dishes. You can efficiently dry dishes without exhausting air into the room where the washing machine is installed. This can prevent damage to furniture such as system kitchens. What's more, the remaining water and leftover food in the washing tank is deodorized and sterilized, so you can remove the dishes from the washing tank. It can be stored for a long time while inside.
