Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to the interior environment of an outdoor self-standing box-type facility similar to each room of a general house, a kitchen, an attic, an apartment, an office building, an air conditioner room, a substation room and the like. It is a ventilation system related to improvement and general.

[0002]

2. Description of the Related Art In the past, hooded ventilators were used for emergency smoke exhaust on kitchen exterior walls with many doors, windows and gaps. Even if buildings and lifestyles have changed and air conditioning has become widespread, and even if each room has become a compact closed space, almost the same type of ventilation will continue. Finally, under several oxygen depletion accidents, a separate air supply port was added to the kitchen and a duct fan was added to the basement for public use to ensure thorough ventilation. However, most of the large architectural uses (both people and substations) require continuous ventilation, and if the old natural ventilation function is secured and the fans do not mainly back up, they are healthy, Energy-saving operation is difficult. With the simple attitude remaining after the window was almost completely opened in the past, the country suddenly shifted to relying on mechanical power and overconfidence. In modern architecture, it is extremely difficult to change or remodel later, including cost factors.In addition, examples of improper positioning of the air supply and exhaust ports, examples of drawing hot air behind the hood under the sunshine into the room, air supply ports There are too many examples of placing furniture and fixtures inside the room. In other words, it seems that there are still many problems to be solved in the current response.

[0003]

[Problems to be Solved by the Invention] It is a human living environment that continuously converts oxygen into carbon dioxide gas and waste heat from body temperature.
Also, if not exhausted quickly, it will be a gas that will settle out when it cools down, an essential condition for a healthy environment. As long as there is a ventilating fan, the air supply is almost the same as in the times when the gap could be supplemented. In particular, the current state of the substation room in the corner of the factory is almost always higher than the outside temperature by more than 10 degrees Celsius, and as soon as the door is opened, everyone can point out the disappointment and the shameful appearance continues.

[0004] 2. In the past, fans were mostly outward-facing fans, and the hoods were guides for their exhaust and eaves to keep out the rain. Recent high-pressure high-power fans are released from a cup-shaped hood at the end of a pipe with a cross section of about 40% of the fan, and have little natural ventilation function in the past due to countermeasures against headwinds, small animals, fire prevention, and the like. That is, when first entering a general apartment, office, meeting place, etc.,
Many people feel the lingering sound of the previous use, and the ventilation of basal metabolic expression is not established as a whole, and seems to be unhealthy.

[0005] 3. It can be said that modern architecture lacks effective and sufficient air supply and exhaust from the time of planning. First, if the air supply behind the fan is insufficient, the noise, the amount of emission, and the motor current decrease, causing the motor to spin. And, in spite of the fact that it is always greater than ever, there are few examples of confirming the suitability of power consumption and operation time. Even if the planner wants a cautious model room, confirmation of the site and measurement and disclosure of data, first of all, the means of management and measurement is not established.

[0006] 4. First of all, noise and crime, including long non-operation hours, are self-discharged by using indoor hot air as a power source with windows and doors closed. It requires meticulous structural measures, and even with a small slope toward the exhaust port, the objectives go a long way, but with little consideration or investment. It is difficult to achieve such a problem due to insufficient air supply, a hood-type reverse slope, or a high temperature caused by sunshine to block the flow. After all, stagnant and stagnant spaces are common.

[0007] 5. Mainly in a substation room, a natural exhaust port and a forced exhaust port for detecting room temperature are often provided in parallel. When the latter fan is turned, the former becomes an air supply port, and the cooling effect on the transformer is very small. Further, when the detected temperature is low, the fan rotates almost continuously, so that if the temperature is set high, the situation becomes similar to a constant temperature room at that temperature. After all, its parallel installation is questionable.

[0008]

[Means for Solving the Problems] An inverted L-shaped square "air supply duct" is provided which is inserted in contact with the bottom of the "through duct" which slightly penetrates the outer wall through the upper side of the room and whose inner wall faces the floor. 2. A front lid-like box-shaped “outer cover” that seals the through-duct and the outer wall and maintains a small gap parallel to the outer wall. The common outer covering of the plurality of through ducts is optional. 3. Hot air is led upward from the ceiling hole (in the kitchen and substation room, the inner hood ceiling). The fan is set so as to be embedded in the downright duct. 4. An opening adjustment is provided at the lower end of the air supply duct. It measures and manages indoor ventilation, and controls air conditioning. Of course, it is not necessary for the substation room or the air conditioning machine room. 5. It is standard that a plurality of the air supply / exhaust sets are dispersed in a large room and concentrated in an inner hood on a transformer in a substation room. The kitchen will be installed alone on a firearm.

(Explanation of the above items) The hot air at the exhaust port is approximately 1 at the sky discharge section of the through duct.
0x speed 1/10 cross section, approximately 3x speed 1 at the entrance of exhaust port
The passage in the / 3 section can be expected. In other words, by utilizing the "buoyancy waterfall" phenomenon, the gap between the outer cover and the outer wall can also be used to prevent blowing and measures against small animals, and the outer cover can be selected with excellent sound insulating material and a design that is in harmony with the outer wall.

[0010] 2. The supply and exhaust volumes are almost equal. Efficiency is involved in the exhaust, but if you hold your hand over the lower end of the air supply duct, you can grasp the ventilation status almost exactly. In addition, high-level operation, such as the state of natural ventilation by the anemometer, the time for replacing the inside and outside air by the fan, and the adjustment of air conditioning conditions, can be achieved for the first time. There is no danger of putting things in front and blocking them, so the ducts can be decorated inside.

3. The updraft in the room draws in the air supply and is accelerated by the air supply, and the heavy cool air in the duct descends like a siphon and re-accelerates its circulation. In addition, air supply from a high position has a low degree of pollution, and is excellent in sound insulation and safety of facilities that generate loud noises such as a substation room and a machine room. Moreover, this tendency is very effective only in highly sensitive modern buildings.

4. The lobby of the hotel has many large rooms with high vaulted ceilings, which is a prerequisite for maintaining a large number of comfortable environments. In this method, air is first supplied from under the wall of the room, and the ceiling is exhausted a little near the center.If the set is placed well, the ceiling is not so high and the room size is arbitrary,
A plan close to the lobby environment according to the number of people becomes possible.

5. In general buildings, there are many strip-shaped designs that represent each floor. In other words, with the outer cover of the present invention, it can be aimed at a building in a healthy environment with minimal power without relying on windows and looking good. Although it is completely separate from air conditioning, it is necessary to pay attention to excess air supply during heating for the air supply port. If it is fully closed, it is almost the same as the conventional one.

FIG. 1 shows an embodiment of the present invention.
It is a front perspective view of a ventilation apparatus. FIG. 2 is a sectional view of the ventilation device. 1 and 2, 1 is a through duct.
An air supply port 3a and an exhaust port 1a are provided. 2 is an inner hood, 3 is an air supply duct, and 3b is an air volume control. Reference numeral 4 denotes an outer cover, which is omitted in FIG. Reference numeral 4a is a stopper for the outer cover. 5 is an inner wall, 6 is an outer wall, 7 is an exhaust fan, and 7a is an exhaust pipe of the exhaust fan. The dashed line 8a indicates the supply air flow, and 8b indicates the exhaust flow. 9 indicates a ceiling of the room.

FIG. 1 is a perspective view and FIG. 2 is a cross-sectional view showing a state in which the present ventilating apparatus is attached to a building. 6 is the outer wall of the building. A square hole is made in the outer wall 6 in the high part of the chamber, into which the through duct 1 is inserted and fixed. An air supply port 3a of an L-shaped air supply duct 3 is arranged in the through duct 1.
The other part is the exhaust port 1a. The through duct 1 is connected to the inner hood 2, and the air supply port 3a is connected to the air supply duct 3, and the air supply duct 3 extends along the inner wall to the lower part of the chamber. The exhaust port 1a and the air supply port 3a of the through duct 1 slightly protrude from the outer wall surface of the outer wall 6. An outer cover 4 is attached so as to cover the exhaust port 1a and the air supply port 3a with a slight gap from the outer wall surface.

As shown by the dashed line in FIG. 2, in the ventilation, a supply air flow 8a and an exhaust air flow 8b are formed. Outside air having a low temperature enters the room through the air supply port 3a, and is guided by the air supply duct 3 to a floor portion of the room where the temperature is low. Due to the suction effect due to the low air pressure in the room and the lowering effect of the cool and heavy air in the air supply duct 3, vigorous air supply is performed. The supply air guided to the lower floor portion of the room is warmed, rises in the room, is guided to the inner hood 2 along the ceiling 9, and is discharged to the outside through the exhaust port 1a. As described above, the ventilation air flow path circulating between the outside and the inside of the room is formed, so that sufficient ventilation is performed.

When the indoor heat generation is large, an exhaust fan can be used together. As shown in FIG.
An exhaust fan 7 is mounted in the inner hood 2, and an exhaust pipe 7a is protruded from the outer cover 4 to exhaust air. With such a structure, natural ventilation and forced ventilation by the exhaust fan are performed in parallel, and therefore, circulation of the ventilation flow is increased, and strong ventilation is performed. Conversely, when large ventilation is not required, an air volume adjustment 3b can be provided at the lower outlet of the air supply duct 3 to reduce the air supply amount.

[0018]

Advantages of the Invention Setting of air supply port (a) The ventilation volume can be measured indoors by the anemometer at the lower end of the air supply port, and the foundation of healthy environmental management is established for the first time.
Because the temperature difference from the outside air and the natural ventilation volume data and the forced exhaust also serves as the forced air supply, it is possible to manage the time of replacement. After all, it is possible and effective only in a modern building with a high degree of sealing. (B) In the case of a kitchen. Fans are almost unnecessary for small cooking, and the usage time is less than half. In the living room, it is used for ventilation of the whole room. Conversely, it completely eliminates the relationship between wind and flame in the case of window-opening cooking and the danger of forgetting to close. (C) Substation room. The fan will be dedicated to emergency overloads and will be cooled to ambient temperature by natural ventilation. Considering the general working hours and the general load of rush hours when commuting, most transformers should have the capacity of one step lower. It saves energy equivalent to a yen. 2. Outer covering and others (a) For general buildings. A building with a magnificent air supply / exhaust port that doubles as an exterior design is also conceivable, and in the end, it is expected that a rare, healthy and energy-saving building, room and equipment will be born. In other cases, an inconspicuous design that is almost perfectly fitted to the exterior will eventually look high and should be recommended.
