This application claims priority to Korean Patent Application No. 10-2023-0144983, filed on Oct. 26, 2023 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
The present disclosure relates to an experimentation table integrated with a harmful gas reduction and air purification system, and more particularly to an experimentation table integrated with a harmful gas reduction and air purification system capable of discharging harmful gases generated from a workbench through a lower space of a chemical shelf of the table and an inner space of a pillar thereof.
Generally, a laboratory table used in a laboratory or an experimental room is provided with a basic table for performing chemical experiments using various chemicals and a shelf space where reagents required for an experiment can be placed. Since various experimental equipment is placed on a laboratory table during the experiment, it is equipped with an upper plate with a larger area than a typical study or office desk.
Accordingly, existing laboratory tables are generally composed of a table frame forming a basic frame, side plates supporting both sides of the table frame, and an upper plate installed on the top of the table frame.
All experiments require various reagents. Among the various reagents required for experiments, reagents that generate harmful gases are stored separately by installing a closed reagent storage device which is a separate, expensive storage device, and a structure for filtering and exhausting pollutants is installed. However, considering the limitations of laboratory space and the movement of an experimenter to a storage device to move reagents needed for each experiment, there has been inefficiency and inconvenience in time utilization.
Accordingly, for convenience of management, reagents needed for general experiments are displayed and stored on a shelf above a laboratory table after experiments, which is inconvenient in that odors are generated there.
Meanwhile, in laboratories with multiple laboratory tables, a fume hood is usually installed to exhaust harmful gases and cross-contamination gases, which may be generated during experiments, through ducts installed outside the laboratory. An exhaust device to generate power is often installed to exhaust harmful gases and cross-contamination gases generated in a limited, partially enclosed space to the outside through a fume hood.
However, such a duct-type fume hood is not equipped with an exhaust device, but the exhaust device is installed to exhaust harmful gases from the limited space of a hood. Accordingly, even when the generation of harmful gases and cross-contamination gases is small or an experiment is conducted only on some of laboratory tables, harmful gases must be discharged throughout the entire laboratory, so there are frequent cases where the experiment is just performed due to the inconvenience of operating a fume hood.
Accordingly, Korean Patent No. 10-0956016 has proposed a simple laboratory table for conducting low-risk experiments equipped with an individual exhaust device that can quickly discharge harmful substances generated during experiments.
However, as this technology has a limitation in that the suction power of harmful gases and cross-contamination gases is concentrated on the front of an experimentation table and the suction power does not reach both sides of the experimentation table, there is a problem with harmful gases and cross-contamination gases remaining on both sides of an experimentation table, especially in the corners, which threatens the health of an experimenter.
In addition, the technology has the problem of polluting the atmospheric environment as hazardous substances are discharged in an unpurified state.
Therefore, the present disclosure has been made in view of the above problems, and it is an object of the present disclosure to provide an experimentation table integrated with a harmful gas reduction and air purification system capable of discharging harmful gases generated from a workbench through a lower space of a chemical shelf and an inner space of a pillar.
It is another object of the present disclosure to provide an experimentation table integrated with a harmful gas reduction and air purification system which has a simple appearance, can provide a comfortable environment, and has excellent space utilization because an air purification system is not exposed to the outside.
It is still another object of the present disclosure to provide an experimentation table integrated with a harmful gas reduction and air purification system wherein a dust collection device can be placed in the form of a drawer at the bottom of a workbench, and when necessary, the dust collection device can be separated from an intake duct and moved, so an arrangement structure can be freely changed and it is convenient to use and manage.
It is still another object of the present disclosure to provide an experimentation table integrated with a harmful gas reduction and air purification system which can improve suction efficiency by installing a fluid guide plate that forms an outward slope between the left and right walls of a filter box and a filter module to guide suction fluid (harmful gases) to concentrate on a filter module.
It is still another object of the present disclosure to provide an experimentation table integrated with a harmful gas reduction and air purification system which has a grill surface, which extends along the transverse direction of a workbench, provided to form an inclined surface from the upper rear side of the workbench toward the lower front side of the workbench, thereby being capable of suctioning and removing harmful gases and cross-contamination substances from a wide area.
It is yet another object of the present disclosure to provide an experimentation table integrated with a harmful gas reduction and air purification system wherein various utilities, including electrical outlets, chemicals/gases, and water piping, are arranged in vertical lines on the pillars of a profile structure, so the appearance of the experimentation table can be configured simply, the risk of contact with harmful gases and cross-contamination gases generated during work can be avoided, and the utility usability of workers can be improved.

In addition, the intake grill may form an inclined surface such that a grill surface extending along a transverse direction of the workbench faces from a rear upper side of the workbench to a front lower side thereof.

Embodiments of the disclosure are provided to more fully explain the present disclosure to those of average skill in the art. Therefore, the shapes and sizes of elements in the drawings may be exaggerated for clearer explanation.
Referring to
According to the present disclosure, harmful gases generated from the workbench 110 are discharged from a lower space of the medicine shelf 120 and an inner space of the pillar parts 130, so there is an advantage of not having to have a separate purification facility, which greatly contributes to cost reduction.
In addition, the present disclosure is to prevent the air purification system from being revealed to the outside, so the experimentation table 100 has a simple appearance, can provide a pleasant environment and provides excellent space utilization.
Referring to
The intake grill 210 may be formed using a lower space of the medicine shelf 120. The intake grill 210 may an inclined surface such that the grill surface 211 extending along a transverse direction of the workbench 110 is directed from a rear upper side of the workbench 110 to a front lower side thereof.
Such a structure of the intake grill 210 allows for the suction and removal of harmful gases and cross-contaminants over a large area above the workbench.
The intake duct 220 may be installed to communicate with the intake grill 210 using the inner space of the pillar parts 130. The intake duct 220 may have an external appearance such as a cylindrical tube body (see
The dust collection device 230 may be installed in the lower space of the workbench 110 and connected to the intake duct 220.
In the present disclosure, the dust collection device 230 may be placed in the form of a drawer at a lower part of the workbench 110, and when necessary, it may be separated from the intake duct 220 and moved, so the arrangement structure can be freely changed, making it convenient to use and manage.
Hereinafter, the dust collection device 230 is described in more detail.
The dust collection device 230 may be moved in a state of being separated from the intake duct 220 by installing a moving caster 232 at a lower part of a device case 231. Here, the moving caster 232 may include a position-fixing means.
The dust collection device 230 may include a purification part 240; and an exhaust fan 260.
The purification part 240 may be installed inside the device case 231 to be connected to the intake duct 220, thereby providing a construction of filtering harmful gases.
The exhaust fan 260 may be installed on an exhaust side of the purification part 240 to discharge purified air to the outside.
The purification part 240 may include a filter box 241; an intake port 242; and a filter module 250.
The filter box 241 may be provided in the form of a hexahedron forming a closed space inside, and the intake port 242 is formed to be connected to the intake duct 220 on the filter box 241.
In addition, the filter module 250 is installed to be spaced apart from the left and right side walls and upper wall of the filter box 241 at a certain distance. Here, a suction fluid distributed to the left and right through a distribution passage 243 at an upper part of the filter box 241 may be collected on sides of the filter module 250 by installing a fluid guide plate 244, which forms an inclined surface in the outward direction, between each of the left and right sides of the filter box 241 and the filter module 250.
A suction fluid (harmful gases) is guided to be concentrated in the filter module 250 by installing the fluid guide plate 244 in a such manner, so that suction efficiency may be improved and the purification efficiency of polluted air may be increased.
The filter module 250 may include a multi-filter 251; a filter housing 252; and an exhaust port 254.
The multi-filter 251 may be provided in a module form consisting of multiple filters including a pre-filter, a carbon filter, and a HEPA filter.
The filter housing 252 may serve as a structure to secure a back pressure-forming part 253 of a certain space by symmetrically installing the multi-filters 251 on opposite left and right sides thereof and spacing apart the multi-filters 251 from each other.
Here, the back pressure-forming part 253 prevents a suction fluid passing through the multi-filter 251 from being concentrated towards the exhaust port 254, thereby providing a vacuum space so that a constant pressure is formed in the entire space.
The filter housing 252 on the lower side of the back pressure-forming part 253 may include the exhaust port 254 formed to communicate with the exhaust fan 260.
In addition, a plasma module 255 that generates negative ions may be installed on one side of the exhaust port 254. Here, the plasma module 255 performs secondary air purification of air, primarily purified from harmful gases and cross-contamination substances through the multi-filter 251, according to a pulse used in a synchronization method of a negative ion generator. Here, the air secondary purified by the plasma module 255 may purify 85% to 99.9% of E. coli, Staphylococcus aureus, and pneumonia bacteria.
However, in the case of the flow distribution plates 245a, 245b and 245, the size of holes placed in an upper part where the flow speed is relatively high is made small to allow small and light particles to pass, and the size of holes placed in a lower part where the flow speed is relatively slow is made large to allow large and heavy particles to pass, thereby improving the purification ability by the multi-filter 251 by controlling an internal flow rate and fluid flow.
Referring to
Here, the module frame 131 may be provided as a profile structure in which one of the four sides is open. In addition, a rail structure is formed at opposite ends of the opening to guide rail combination with the frame cover 132.
In addition, various utilities 133a, 133b and 133c including electric outlets, faucets, gas valves, air valves, cocks, LCD module panels, and power ON/OFF switches may be installed using the frame cover 132 of the parts 130.
By arranging these various utilities (133a, 133b, 133c) in vertical lines on the pillar parts 130 of the profile structure, the appearance of the experimentation table may be configured simply, harmful gases and cross-contamination gases generated during work may be eliminated, the risk of contact with harmful gases and cross-contamination gases generated during work may be avoided, and work efficiency may be improved by improving the utility usability of workers.
The utilities installed on the frame cover 132 may be freely changed depending on the field of use, and assembly may be improved through a slide combination with the module frame 131, allowing for easy attachment and detachment, thereby increasing user convenience.
Referring to
The length of the pillar extension 130 may be cut to suit spaces with different internal heights, such as offices, research institutes, and laboratories.
Here, a supply line includes all utilities including 220V power lines and chemical utilities such as gas pipes, air pipes, and water pipes. The supply line is a structure that comes down from a ceiling, and the organization of utilities can be simplified by forming a line inside the module frame 131 to connect to various utilities. In addition, as the supply line is installed inside a module frame where the power source and various pipes below the table come down to the ceiling, it is possible to avoid safety accidents such as electric shorts due to contact with moisture.
In addition, since there is no need to install piping at the bottom of the workbench, there is no interference with the movement of workers and a safe laboratory environment can be established.
As apparent above, the present disclosure provides an air purification system allowing harmful gases generated from a workbench to be discharged through a lower space of a chemical shelf and an inner space of a pillar. Accordingly, there is a cost-saving effect because there is no need to install a separate purification facility, a simple appearance and comfortable environment can be provided because the air purification system is not exposed to the outside, and space utilization is excellent.
In addition, a dust collection device can be placed in the form of a drawer at the bottom of a workbench, and when necessary, the dust collection device can be separated from an intake duct and moved, so an arrangement structure can be freely changed and it is convenient to use and manage.
In addition, the present disclosure can improve suction efficiency by installing a fluid guide plate that forms an outward slope between the left and right walls of a filter box and a filter module to guide suction fluid (harmful gases) to concentrate on a filter module, and can improve the purification efficiency of polluted air.
In addition, the present disclosure provides a grill surface, which extends along the transverse direction of a workbench, provided to form an inclined surface from the upper rear side of the workbench toward the lower front side of the workbench, thereby being capable of suctioning and removing harmful gases and cross-contamination substances from a wide area.
In addition, the present disclosure is characterized by arranging various utilities, including electrical outlets, chemicals/gases, and water piping, in vertical lines on the pillars of a profile structure, so the appearance of the experimentation table can be configured simply, the risk of contact with harmful gases and cross-contamination gases generated during work can be avoided, and the utility usability of workers can be improved, thereby improving work efficiency.
The present disclosure has been described with reference to an embodiment shown in the accompanying drawings, but this is merely illustrative, and those skilled in the art can understand that various modifications and other equivalent embodiments can be made therefrom. Therefore, the true scope of protection of the present disclosure will be determined solely by the scope of the appended claims.
