Fog machines are devices that emit a dense vapor used to simulate fog or smoke. Typically fog machines are used for entertainment and decorative purposes. For example, fog machines may be used to create fog effects for concerts, plays, haunted houses, Halloween displays, etc.
One challenge that exists with fog machines relates to issues with creating a realistic fog effect in view of the fact that the vapor tends to rise from the ground more quickly than actual fog would rise from the ground. This can cause the vapor to be thinner than desired and to be at a height that is higher than desired. One method that has been used to overcome this is to not use a fog machine at all, but rather to use sublimating dry ice to create a fog effect. However, dry ice is expensive, is difficult to handle because of extreme cold temperatures, and creates an asphyxiation hazard if used in confined spaces.
The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as those described above. Rather, this background is only provided to illustrate one exemplary technology area where some embodiments described herein may be practiced.
One embodiment illustrated herein includes a vapor chiller. The vapor chiller includes a chiller vessel configured to store a cooled substance. The chiller vessel includes a plurality of chambers. Each chamber in the plurality of chambers is configured to concentrate the cooled substance at a bottom of the chamber. The vapor chiller further includes a fan coupled to the chiller vessel. The fan is configured to direct vapor through the chiller vessel across the cooled substance in the bottoms of the chambers.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
Additional features and advantages will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the teachings herein. Features and advantages of the invention may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. Features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.
In order to describe the manner in which the above-recited and other advantages and features can be obtained, a more particular description of the subject matter briefly described above will be rendered by reference to specific embodiments which are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments and are not therefore to be considered to be limiting in scope, embodiments will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
Embodiments illustrated herein relate to a vapor chiller configured cool vapors from fog machines. In particular, the vapor chiller is configured to store a cooled substance (such as ice). The chiller vessel includes a plurality of chambers. Each of the chambers in the plurality of chambers is configured to concentrate the cooled substance at a bottom of the chamber. The vapor chiller further comprises a fan coupled to the chiller vessel. The fan directs vapor through the chiller vessel across the cooled substance in the bottoms of the chambers.
An example embodiment is illustrated in
The vapor chiller vessel 101 includes a plurality of interconnected chambers 106-1, 106-2, and 106-3. While three chambers are shown in the example of
Each of the chambers is configured in size and shape to concentrate a cooled substance 112 at the bottom of the chamber. In some embodiments, the cooled substance 112 may be ice. Alternatively, or additionally, the cooled substance may be dry ice, a mixture of water, ice, and salt (to facilitate cooling below the normal freezing temperature of water), or other cooled substances. In the example illustrated in
In the example illustrated in
The vapor chiller 100 further comprises a fan 120. For example, the fan 120 is configured to assist with forcing the vapor 110 through, and out of, the vapor chiller 100. In some embodiments, the fan 120 may be coupled to a controller configured to vary the speed of the fan. Varying the speed of the fan can be used to control how thick the vapor is that is output from the vapor chiller 100. Slower speeds can be used to output a thicker vapor, while faster speeds can be used to output a thinner vapor.
With reference now to
The lid 122, in some embodiments, further comprises a baffle 126. The baffle 126 is configured in size and shape to extend into one or more of the chambers in a fashion that forces vapor towards the cooled substance 112.
In some embodiments, the vapor chiller 100 includes one or more drains 128. The drains may be included to allow for draining the cooled substance 112 when in liquid form whether due to melting or otherwise.
Other configurations may be implemented. For example,
The vapor chiller vessel 501 includes a plurality of interconnected chambers 506-1, 506-2, and 506-3. While three chambers are shown in the example of
Each of the chambers 506-1, 506-2, and 506-3 is configured in size and shape to concentrate a cooled substance at the bottom of the chamber. In
In the example illustrated in
The vapor chiller 500 further comprises a fan 520 between a vapor chamber 506-4 and the chamber 506-3. The vapor chamber 506-4 is formed by including an internal wall structure 533. The fan 520 is configured to assist with forcing the vapor through, and out of, the vapor chiller 500, through a vent 530 in the front wall 532. In some embodiments, the fan 520 may be coupled to a controller configured to vary the speed of the fan. Varying the speed of the fan can be used to control how thick the vapor is that is output from the vapor chiller 500. Slower speeds can be used to output a thicker vapor, while faster speeds can be used to output a thinner vapor.
With reference now to
Note that while in previously illustrated embodiments, the lid 122 included a baffle 126, in the illustrated example, the baffle 526 is part of the vapor chiller vessel 501. The baffle 526 is configured in size and shape to force vapor towards the cooled substance. Note that in this example, the vapor chiller vessel 501 comprises a space 534 between the baffle 526 and the bottom 504. For example, the space may be 1 inch in height. Similarly, a space 536 may be implemented between the baffle 508 and the bottom of the lid 522. The space 536 may be 1 inch in height. Note that other dimensions may be used in other embodiments. The baffle 526 may be coupled to the sides 502 to cause the baffle 526 to be tight to the lid 522 when the lid 522 is installed on the vapor chiller vessel 501.
