The present invention relates to a hot air recirculation structure of the dish dryer, and more particularly, the outside air sucked by the blower fan provided in the hot air supply chamber of the dish dryer is heated by a heater, and then the heated hot air is introduced into the drying room to dry the dishes. By discharging only a part of the hot air and recirculating most of it in the process of discharging the hot air in the drying room to the outside, it is possible to improve the drying performance even when the heater capacity is small, and to reduce the power consumption in comparison with the conventional method. The hot air ash circulation structure of the dish dryer to have a.

In general, the dish dryer belongs to a home appliance that is capable of sterilizing a container with a drying action by forcibly drying water by a high temperature of a heater generated by electric resistance by receiving power from the dish after washing.

Today, as the overall level of public hygiene is increasing, more households have dish dryers, and the demand is gradually increasing.

As the demand is gradually increased in homes and restaurants in recent years, the development of dish dryers having more advanced functions and competitive prices is accelerating, and as a result, various kinds of dish dryers having higher functions are gradually increasing. It is commercially available.

One of such dish dryers is a high temperature hot air dish dryer having both the above washing and drying functions, and using high temperature hot air for drying.

This high temperature hot air dish dryer can dry dishes automatically using high temperature hot air, which makes it more hygienic and reduces housework labor than removing the moisture of each dish using dishcloth which is highly contaminated. have.

The high temperature hot air dish dryer has already been proposed and used in various forms, one example of which is as shown in FIGS. 1 and 2.

That is, a typical high temperature hot air dish dryer has a main body 100 forming an appearance and a drying chamber 120 for storing dishes to be dried on the upper side of the main body 100.

At this time, a drying rack (not shown) such as a shelf on which the dishes to be dried are placed is mounted in the drying chamber 120.

In addition, the drying chamber 120 is sealed by a door 130 that can be opened and closed, and a hot air supply chamber 140 for supplying hot air to the drying chamber 120 is formed under the drying chamber 120.

In addition, an exhaust port 210 is provided at one side of the upper end of the drying chamber 120 so as to flow into the drying chamber 120 to discharge the hot air drying the wet dishes.

One side of the hot air supply chamber 140 is provided with an intake hole 150 for sucking outside air from the outside, and the other side is provided with a discharge hole 160 formed through the drying chamber 120.

In addition, a hot air supply pipe 170 having one end communicating with the intake hole 150 and the other end communicating with the discharge hole 160 is installed inside the hot air supply chamber 140.

At this time, the inside of the hot air supply pipe 170 is driven by the fan motor 200 is supplied with power, respectively, the blowing fan 180 that can suck the outside air and the heater 190 that can heat the sucked outside air is Is placed.

And, although not shown, a drip tray for receiving the water falling on the wet dishes (dry goods) in the drying chamber and the condensate water condensed by the moisture generated during the drying process is disposed on the bottom side of the drying chamber.

Therefore, the operation state of the conventional high temperature hot air dish dryer having the configuration as described above is as follows.

First, by operating a switch provided in the main body 100 of the dish dryer and setting the operating time, and then supplying power to the dish dryer, the blower fan 180 is driven to the outside through the intake hole 150 The air is sucked, and at the same time, the heater 190 generates heat, thereby heating the sucked outside air.

In addition, the outside air sucked by the blower fan 180 is heated to a high temperature while performing heat exchange by the heat generated by the heater 190, and then flows into the drying chamber 120 through the discharge hole 160. As a result, the dried dishes are dried.

After drying dishes in the drying chamber 120 by hot air, the hot air is discharged to the outside through the exhaust port 210.

However, in the general dish dryer having the above configuration has the following problems.

That is, a predetermined time is required for the temperature of the hot air supplied according to the capacity of the drying chamber 120 of the conventional dish dryer to be raised to an appropriate temperature. In particular, when the hot air is blown out, the drying chamber 120 is inside. The temperature rise time of has a relatively long time has a problem that the drying effect and sterilization effect is reduced.

In other words, in the conventional dish dryer, after drying the dishes (not shown) in the drying chamber 120, the hot air is always sucked freshly to make hot air for drying the wet dishes while discharging all the hot hot air to the outside through the exhaust port 210. A lot of power is consumed in the process of heating and supplying the external air to the heater 190.

As such, as the heater 190 generates heat, the heat generation time of the heater 190 increases so that the heater 190 reaches a minimum hot air temperature suitable for drying the dishes (blood to be stored) stored inside the drying chamber 120. There was a problem being consumed.

In particular, the greater the amount of heat discharged to the outside, the more time it takes for the temperature inside the drying chamber 120 to reach a constant state, which may not satisfy the desire of the consumer for fast drying.

As such, the conventional dish dryer has to set a relatively long time for drying for stable drying and sterilization, which causes unnecessary waste of power, and prevents the effect of drying and sterilization from occurring within a set time. There has been a problem of lowering the reliability of the user.

The present invention is designed to solve the above problems, an object of the present invention is to heat the outside air sucked by the blowing fan provided in the hot air supply chamber of the dish dryer in the heater, and then introduced the heated hot air into the drying room to By drying and discharging only a part of the hot air in the process of discharging the hot air in the drying room to the outside, and recirculating most of the hot air, the drying performance can be improved even when the heater capacity is small, and the power consumption can be relatively reduced. It is to provide a hot air recirculation structure of the dish dryer so as to secure the consumer's reliability by improving the function of the product to have the advantage.
