Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a dish dryer that dries dishes using hot air from a heater.

BACKGROUND OF THE INVENTION Conventionally, this type of dish dryer has been constructed as shown in FIG. That is, a heater box 103 having a quartz tube type heater 101 (hereinafter abbreviated as heater) is installed in the inner bottom of the main body 104 of the dish dryer, and a heater box 103 is installed at the top of the heater box 103 to uniformly discharge the hot air inside the heater box 103 to the top. An exhaust plate 102 is provided, and a water receiver plate 106 is screwed (not shown) to the main body 104 adjacent to the exhaust plate 102.
The heater 101 heats the dishes 106 while raising the internal temperature of the upper drying chamber 106 to dry the dishes 108 in the dish basket 107. Furthermore, since a larger amount of radiant heat is generated than the heater 1o1, if the heater box 103 is made thinner, the exhaust plate 102 will also be locally overheated, and the water tray 105 will also be locally overheated, so the heater box 103 has sufficient dimensions.

Problems to be Solved by the Invention In such a conventional configuration, there were problems in that the heater 1o1 was energized intermittently to prevent local overheating and that the drying time of the tableware was extended.

The present invention solves these conventional problems.
The purpose is to provide an easy-to-use dish dryer that eliminates local overheating while reducing the thickness of the heating section, equalizes the average temperature of the dishes in the water tray, and shortens drying time. It is.

Means for solving the problem In order to solve this problem, the present invention uses an expansion metal to disperse the heat rays radiated from the heater and to effectively generate convective heat. A hot plate is installed between the heater and the water tray.

Function: With this configuration, the radiant heat generated from the heater passes through the diagonal direction between the expansion metals due to the directionality of the expansion metal mesh, and the water receiver heats parts of the dish that are far away from the heater. , Most of the radiant heat in the upper direction of the heater is blocked, and the radiant heat is consumed in heating the expansion metal, and is transmitted inside the expansion metal as conduction heat, and flows from the gap in the expansion metal to the upper part of the wide area as convection heat. The heat generated by the heater can be used to heat the water tray with little temperature gradient.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In FIG. 1, reference numeral 1 denotes the main body of the dish dryer, which is equipped with a heater box 1o equipped with a quartz tube heater 7 at the inner bottom, and above the heater box 10 is a water tray 2.
A dish basket 4 on which tableware 3 is placed is placed above the water tray 2. Furthermore, the opening at the top of the main body 1 of the dish dryer is covered with a lid 6 having an exhaust hole 6. A heat equalizing plate 8 is provided between the quartz tube heater 7 and the water tray 2, and this heat equalizing plate 8 is made of expansion metal with good thermal conductivity. The direction of the hole in the expansion metal is such that the water receptacle is directed toward the low slope side of the dish 2. Further, a heat ray reflecting plate 9 is provided at the lower part of the heater 7 to reflect the radiant heat to the upper heat equalizing plate 8 to prevent the heater box 10 from overheating. In addition, the water receptacle in the main body 1 of the dish dryer is provided with a vent 1 in the supporting part of the dish 2 through which convective heat can rise.
1 is provided.

In the above configuration, when the heater 7 is energized, radiant heat and convection heat are generated from the heater 7. The heat rays radiated downward are reflected by the reflection plate 9 and directed upward, and the heat rays radiated upward are directed toward the upper part of the heater 7 and the higher slope side of the dish 2 by the soaking plate 8. This is prevented by the directionality of the metal holes, and the water receiver is irradiated only on the low slope side of the dish 2. Therefore, the low slope portion of the dish 2 of the water tray is heated by the radiant heat. On the other hand, the radiant heat blocked by the heat equalizing plate 8 heats the heat equalizing plate 8 and generates secondary radiant heat from the surface of the heat equalizing plate 8.
Heat a large area. On the other hand, the convection heat from the heater 7 flows from the center of the heater to the high slope side of the dish 2, and the water dish heats the dish 2, thereby reducing the difference in temperature between the surfaces of the water dish. The convection heat flowing along the back surface of the dish 2 in the water tray enters the drying chamber containing the tableware 3 through the vent 11.

The heated water tray generates radiant heat and convection heat from the surface of the dish 20, enters the drying chamber containing the dishes 3, and dries the dishes 3, and the moisture is released outside the chamber through the exhaust hole 6 of the lid body 6. Ru. As mentioned above, by dispersing the heat from the heater 7 to the water tray 2, the heating section can be made thinner and the amount of heat dissipated can be increased, making the inside of the drying cabinet with a short drying time more effective. It is possible to provide a usable dish dryer.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, radiant heat can be dispersed by interposing an exonoshiron metal heat equalizing plate between the dish and the quartz tube heater.
Even if the distance between the heater and the water tray is shortened, the water tray can reduce the difference in the surface temperature distribution of the tray, and the amount of heat generated by the heater can also be increased, making the temperature distribution inside the refrigerator more uniform and increasing the temperature inside the refrigerator. The effects of shortening the drying time and making the interior of the dish drying chamber larger as the heating section can be designed to be thinner can be achieved.
