It is desirable that the product storage section be provided with preheating means for preheating the product.

The preheating means is preferably divided into a low temperature portion on the opening side of the housing and a high temperature portion on the opposite side.
The preheating means is not particularly limited, but a plate heater can be used, for example.

In the open showcase as described above, the air curtain is basically not formed during heating. Further, since the heating means is provided for each of the product display shelves for displaying the products, the product on the product display shelf is directly, efficiently, quickly and accurately heated to the set temperature by the heating means. be able to. In addition, a product storage unit is formed between the lowermost product display shelf and the inner bottom of the housing, and a cover member that covers the front surface side of the product storage unit (that is, the opening side of the housing) is provided. . Therefore,
For example, it is possible to reliably avoid a situation in which a user such as an infant accidentally puts his / her hand in the bottom of the housing. Also,
By installing the cover member, the product display space is substantially reduced, but by forming the product storage section in the inner bottom of the housing, the inner bottom can be effectively used without forming a dead space. . That is, the amount of products stored in the housing does not decrease.

The products in the product storage section formed as described above are heated to a certain extent by the radiant heat from the heating means of each product display shelf, the heat transfer in the warehouse, etc., but the product storage section is provided with preheating means. With this, the inside of the product storage unit can be heated substantially independently to a desired temperature.

The preheating means includes a low temperature portion (for example, about 37 ° C., which is approximately the same as human body temperature) on the housing opening side and a high temperature portion (for example, a drinkable temperature of 50 to 60 ° C.) on the opposite side. By dividing into, it is possible to surely prevent an unexpected situation even if the user accidentally puts his or her hand in the product storage unit. Further, by taking out the product to be replenished to the product display shelf from the high temperature side, the temperature can be set to the optimum temperature or a temperature close thereto in advance, so that the user or the like can always be provided with the product in the optimum heating state.

Since the heating means and the preheating means can be constituted by, for example, a general-purpose plate heater or the like,
There is no significant increase in cost due to the increase in the number of parts. Further, since basically the same heating means such as a plate heater can be used for each display shelf, cost reduction can be achieved by promoting the sharing of parts.
