Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an open show case with a humidifier used in supermarkets, particularly for displaying fruits and vegetables and soft vegetables to be eaten raw.

[Conventional technology]

Hitherto, open show cases have been humidified by ultrasonic humidifiers to maintain the quality of products and to display them, and a conventional open show case with the above structure is shown in FIG. 3.

A cooling air passage 3 is formed inside the case body 1 of this show case, and the cooling air in the cooling air passage 3 is blown out from the air outlet 4 to the product takeout opening 2 to form an air curtain A. Inlet 5
The air is sucked in from the air, passes through a fan 6, is cooled by a cooler 7, and is blown out from an air outlet 4 again.

By the way, the upper plate 1a of the case body 1 is provided with a humidifier 8 that uses ultrasonic waves to turn moisture into a mist. It is inserted into the upper passage 3a of the air passage 3 and provides moisture to the cooling air for forming the air curtain from the spray nozzle 8b.

In such a conventional show case, a portion of the cooling air containing mist moisture 9 blown out from the air curtain outlet 4 enters the case on the way to the inlet 5 and disturbs the products on the shelves 9a and 9b. Although it cools and humidifies, most of the cooled air is directly sucked into the suction port 5, and as a result, the humidified air is not evenly distributed over the products on display, making it impossible to achieve the purpose of maintaining the freshness of leafy vegetables. Ta.

Furthermore, the conventional show case has the following drawbacks.

(a) The cooling air coming out of the air outlet becomes a vortex on the top surface of the shelf board, and mist of moisture adheres to the display mirror 10, causing it to become cloudy, and the product's display effect is lost.

(b) Since a mist of air is ejected from the top of the case, users do not actually have to worry about getting wet, but it creates the illusion that they are getting wet, making them hesitant to put their hands inside the case, which can lead to sales promotion. purpose cannot be achieved.

(c) Most of the sprayed humidified air is not absorbed by the product, but is inhaled into the inlet and enters the cooler, which tends to cause condensation on the cooler, reducing the operating efficiency of the cooler.

[Problem that the invention attempts to solve]

In order to solve the above-mentioned drawbacks, the present invention introduces a part of the cooling air for forming the air curtain into a kind of chamber inside the case, where the mist moisture and cooling air are mixed, and the cooling air is mixed with the cooling air from the back of the case. By ejecting it onto the top surface of the plate, the above-mentioned drawbacks can be eliminated.

[Structure of the present invention]

The open show case with a humidifier of the present invention has a product takeout opening formed in the front part, and an air outlet for forming an air curtain to the product takeout opening at the upper edge of the product takeout opening. is,
and an air inlet for sucking air from the air outlet is formed at the lower edge of the product take-out opening, and an air passage for blowing out the air curtain air sucked from the air inlet again from the air outlet. In the open case where a cooler is arranged in the air passage, the upper part of the inner case is supplied with mist moisture from the humidifier, and the lower part is a chamber with an outlet for humidified cooling air. In addition, a baffle plate is provided in the air passageway to invert a part of the air from the cooler and introduce it into the chamber in the inner case through the cooling air hole in the back plate of the inner case, and a baffle plate is provided in the air passage to invert a part of the air from the cooler and introduce it into the chamber in the inner case through the cooling air hole in the back plate of the inner case. The cooling air containing moisture is blown out onto the shelf board.

[Effect]

An air curtain is formed at the product take-out opening using the cooling air that does not contain mist moisture, and the cooling air containing moisture can be flowed from the back of the case to the upper surface of the shelf board.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to a specific example shown in the accompanying drawings.

In FIG. 1, the same components as those in FIG. 3 are given the same reference numerals, and explanations of these components will be omitted.

As shown in FIG. 1, a humidifier 8 is installed in the upper part of the case body, and the spray port 8b of the humidifying pipe 8a from the humidifier 8 is connected to the back plate 11 of the inner case and the ceiling plate 1.
2 and the mirror 10.
It is open inside.

Further, a cooling air hole 14 is formed in the upper part of the back plate 11 to communicate the cooling air passage 3 and the chamber 13, and in this part, a part of the cooling air flow rising in the cooling air passage is made a U-turn. A baffle plate 15 is provided to allow the water to flow into the chamber.

FIG. 2 shows the detailed structure around the chamber. The upper end of the mirror 10 is attached to a mirror retainer 16a.
The inner case is attached to the ceiling plate 12 by
The lower end of the mirror 10 is supported by a mirror retainer 16b, and this retainer is attached to the rear plate 11 by screws or the like via spacers 18, with outlets 13a opened at appropriate intervals, and louvers 17a, 17b, and 17c are provided at the aforementioned intervals.

In the embodiment described above, the cooling air cooled by the cooler 7 passes through the cooling passage 3, is blown out from the outlet 4, forms an air curtain A, and is sucked in through the suction port 5, repeating the circulation. At this time, a part of the cooling air in the cooling air passage 3 is reversed by the baffle plate 15 and blown into the chamber 13 through the cooling air hole 14.

By the way, moisture that has been atomized by the humidifier 8 is blown out from the spray port 8b into the chamber 13, and the cooling air that has entered the chamber 13 through the cooling air holes 14 is mixed with the atomized moisture 9 and released into the chamber 13. The product is sent into the case (product storage room) from the lower outlet 13a of the product. At this time, the louvers 17a, 17
The cooling air deflected by b and 17c has directionality, and part of it flows over the top surface of the shelf board 19a to supply moisture to the products, and part of it flows through the through holes 20 provided in the back plate attachment part of the shelf board 19a. Pass through the lower shelf board 1
9b, and the products on each shelf are sprayed with moisture from the back of the shelf.

[Effects of this invention]

As described above, according to the present invention, since the cooling air containing moisture can be flowed from the back of the shelf along the surface of the shelf board, moisture can be uniformly and sufficiently supplied to the products on the shelf board. In addition, the louvers blow out directional cooling air from the bottom of the mirror onto the shelf, which prevents the louvers from fogging up and also prevents customers from feeling wet when approaching the case. , enhances the presentation effect of the product and promotes sales.

Furthermore, since the air curtain is formed by cooling air that does not contain much moisture, excess moisture does not cause dew condensation on the cooler, increasing the operating efficiency of the cooler.
