Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial hoarfrost display device. 2. Description of the Related Art A conventional artificial rime generating apparatus has a cooler in which trees are arranged in a sealed cooling chamber, and a cooling coil and a blower are connected to a refrigerator installed outside the cooling chamber by a reciprocating refrigerant pipe. The cooling air generated in the cooling chamber is blown into the cooling chamber, the cooling chamber is directly cooled to a predetermined temperature, and water and compressed air are simultaneously blown into the cooling chamber via a two-fluid nozzle from a water tank and an air compressor installed outside the cooling chamber. , Spouting fog,
Compressed air generated by another air compressor installed outside the cooling chamber is blown into the cooling chamber to generate an airflow, and the mist is sprayed on the tree by being carried on the airflow, and a means is provided for icing to generate rime ice. Artificial rime generators are known. [0003] However, the artificial rime generator has the following problems. (1) The compressed air blown into the cooling chamber collides with the side wall, the ceiling, etc. of the cooling chamber, and is reflected and becomes a reflected wave, which is a complex airflow in which these are combined, and a strong wind in a constant direction blows in the natural world. It is not possible to achieve the directional hoarfrost that can sometimes occur. (2) Since expensive equipment such as an air compressor must be installed, equipment costs increase. (3) Since the cooler is installed in the high-humidity cooling room, the moisture lands around the fins of the cooling coil, and the gap between the fins is closed. , Cooling efficiency is reduced. [Patent Document 1] JP-A-2000-146388 [Patent Document 1] JP-A-2000-146387 [Patent Document 1] JP-A-2000-146386 [Patent Document 1] JP-A-2000-146377 SUMMARY OF THE INVENTION The present invention has been made to solve the problems described in the background art, and has a relatively low facility cost and a low cooling efficiency. It is an object of the present invention to provide an artificial hoarfrost display device capable of generating directional hoarfrost that can be generated when a strong cross wind blows in a certain direction without reducing it. [0006] An artificial hoarfrost display apparatus of the present invention is a box-shaped refrigerator having an opening at the front and having a rectangular cross section made of a cool air conducting member at predetermined intervals in the left, right, up and down directions. At the rear end of the cylinder,
Airtightly attached to the back of the freezer, sealing the opening at the rear of the cylinder, at the front of the cylinder, spaced from the left and right side walls of the cylinder inward, and more than the depth of the cylinder Left and right air conditioning walls of a width that is short by a predetermined length are erected, walls are fixed to the rear ends of the left and right air conditioning walls, and a blower is provided in a space formed by the walls, the cylindrical body, and the back of the freezer. In addition to installing a fog outlet for ejecting the fog generated by the fog generator, installing a cooler in the cooling room of the freezer, forming the left and right air conditioning walls and the floor and ceiling of the cylindrical body The opening provided is sealed with a glass window, and the remaining opening between the cylindrical body and the freezer except for the glass window is sealed with a heat insulating wall. (1) A crosswind containing fog of a certain direction and a certain speed is blown onto an exhibit such as a tree or a grass arranged in an exhibition room,
Directional rime can be attached. (2) Since no mist flows into the cooling chamber where the cooler is installed and the humidity does not become high, icing of the cooling coil of the cooler on the fins can be prevented or reduced, and thus the cooling efficiency of the cooler is reduced. Reduction can be prevented. (3) Since expensive equipment such as an air compressor is not required and only a blower is required, the equipment cost is not increased. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Directional hoarfrost that can be generated when a strong cross wind blows in a certain direction can be generated with relatively low equipment cost and without reducing cooling efficiency. The purpose of providing an artificial rime ice display device was realized by indirectly cooling the exhibition room to a predetermined temperature and blowing a crosswind containing fog in a certain direction and at a constant speed from one of the left and right wind regulating walls of the exhibition room. An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a rear end of a box-shaped refrigerator 2 having a rectangular cross section made of a cooling air conducting member is placed on a box-shaped refrigerator 1 having a front opening at predetermined intervals in the left, right, up and down directions. And the opening at the rear of the cylinder 2 is sealed. The cold air conducting member is a metal plate made of a copper plate, an aluminum plate, a stainless steel plate, a galvanized steel plate, or the like. Also,
The cylindrical body 2 does not need to have a tubular structure in which the left and right side walls a, a, the floor b, and the ceiling c are integrally continuous and have no joint, and the left and right side walls a, a, the floor b, and the ceiling c Any structure may be used as long as they are individually joined, airtightly treated with putty or the like, and finished in a tubular shape so that the mist 9 does not leak outside from the joints. [0010] The predetermined intervals vertically and horizontally include, for example,
As shown in FIG. 3, the space for installing the cooler 12 on the left side of the freezer 1 is provided.
This is an interval for circulating the cooling air of No. 2 in the flow indicated by the arrow X. In FIGS. 1 and 3, reference numeral 15 denotes a column serving as a spacer for obtaining a lower space. As a matter of course, the cooler 12 may be installed on the right side of the freezer 1. The left and right side walls a,
The left and right wind regulating walls 4 and 4 having a width W shorter than the depth L of the cylindrical body 2 by a predetermined length are spaced from the inner side from a, and the wall 5 is fixed to the rear ends of the left and right wind regulating walls 4 and 4. are doing. The width W shorter than the depth L of the cylindrical body 2 by a predetermined length is, for example, as shown in FIG.
A space portion 6 formed by the wall 5, the cylindrical body 2, and the back surface 3 of the freezer 1 is provided, and a fog outlet 10 for blowing out the fog 9 generated by the blower 7 and the fog generator 8 is provided in the space portion 6. Is a width W necessary to secure a space that can be used. The reason why the air conditioner walls 4, 4 are erected from the left and right side walls a, a of the cylindrical body 2 with an interval therebetween is to secure a gap acting as a wind tunnel. As shown in FIG. 4, for example, as shown in FIG. 4, the air-conditioning walls 4 are arranged in a grid pattern at intervals, and when the air passes through the air-conditioning walls 4, the wind is directed in a certain direction. It is conditioned. The air conditioning walls 4 and 4 shown in FIG. 4 are merely examples, and the present invention is not limited to this configuration. Any wall provided with a mechanism capable of adjusting the wind in a certain direction can be applied. For example, as shown in FIG. 2, a blower 7 is installed in a space 6 formed by the wall 5, the cylindrical body 2 and the back surface 3 of the freezer 1, and a mist 9 generated by a mist generator 8 is formed. Is provided. In FIG. 2, reference numeral 17 denotes an intake pipe which prevents the pressure of the fog generating chamber 18 from dropping and the pressure of the space 6 and the exhibition room A from rising when the fog 9 is ejected, and facilitates the ejection of the fog 9. Then, the valve 17a of the intake pipe 17 is opened to bring the intake air. When the blower 7 is driven to eject the mist 9 into the space 6, for example, as shown in FIG. 2, when the mist 9 rides on the wind indicated by the arrow Y and passes through the right regulating wall 4, Exhibit room A
To hit the exhibit B and land on it, generating directional rime ice. As the mist generator 8, a commercially available ultrasonic humidifier capable of generating fine water vapor can be used. The amount of the sprayed mist is adjusted by adjusting the degree of opening and closing of the valve 8a of the mist generator 8. The openings formed by the left and right air conditioning walls 4 and 4 and the floor b and ceiling c of the cylindrical body 2 are sealed with a glass window 13 as shown in FIG. The remaining opening between the cylinder 2 and the freezer 1 is sealed by a heat insulating wall 14, as shown in FIG. In addition, it is preferable to use a glass window having a function of preventing dew condensation so that the glass window 13 can be easily observed. [Industrial Applicability] [0018] Directional rime which can be generated when a strong constant crosswind blows in the natural world can be generated and displayed, so that it can be used for learning in educational institutions and the like.
