Description

  The present invention relates to a steamer, and more particularly, to a steamer that prevents water droplets generated by steam for humidifying and keeping warm of a display product from dropping from the top surface of a main body case constituting the steamer onto the display product.

In recent years, for example, in order to heat and sell so-called Chinese buns such as cooked buns and meat buns at stores such as convenience stores, steamers having a humidification and heat retention function have been installed.
The steamer as described above is configured to steam steamed buns, meat buns, and the like placed on food display shelves in the steamer main body constituting the steamer by generating steam from below the steamer main body by steam generating means (for example, Patent Document 1).

However, in the steamer disclosed in the above Patent Document 1, the steam generated by the steam generating means is filled in the steamer main body and adheres to the inner surface of the top plate of the steamer main body. It becomes.
If that happens, the water drops will go nowhere, and will drip from the inner surface of the top board onto products such as Anman and Meatman. As a result, buns and meat buns have no value as commodities and cannot be sold.

  Therefore, as shown in FIG. 9, water droplets generated by the steam hang down on the product display shelf 150 at a position near the top plate 125 between the top plate 125 of the main body case 111 and the uppermost product display shelf 150. In order to avoid this, the steamer 110 provided with the drip-proof glass 114 may be used.

The drip-proof glass 114 in the steamer 110 is installed in an inclined shape with a predetermined angle so that the front side becomes lower from the back side to the front side of the main body case 111. And when the vapor | steam which generate | occur | produced with the vapor | steam generation means 140 arrange | positioned at the lower part of the main body case 111 hits the inner surface of the top plate 125 and becomes a water droplet, the water droplet falls on the upper surface of the drip-proof glass 114. It is supposed to be.
Water droplets flow down from the tip of the drip-proof glass 114 along the inner surface of the inner glass 116 constituting the double-glazed glass container 115 having a U-shaped cross section, and in the main body case 111, It is configured to be collected in a water droplet collection part (not shown) provided on the lower end side.
