Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a reforming ventilator that is installed in place of an existing ventilator, and more particularly to a reforming ventilator in which outside air is always introduced into a room and indoor air is always kept clean.
[0002]
[Prior art]
In recent years, housing has become highly airtight and highly insulated, and the concentration of carbon dioxide becomes too high unless sufficient ventilation is provided, and the concentration of formaldehyde and volatile organic compounds (VOCs) is particularly high in newly built houses. May be too high. In addition, inadequate ventilation can result in increased humidity, mold and ticks, and allergies.
[0003]
For this reason, in order to maintain clean air in an airtight apartment such as a condominium, it is desirable to ventilate frequently by using a ventilator that has been installed in the house. Conventionally, sufficient ventilation has not been performed to dislike operating noise and save electricity bills.
As a result, in extreme cases, an open heater was used without ventilation for a long time in a closed room, which resulted in a lack of oxygen. Further, even when a heater is not used, the carbon dioxide concentration exhausted by breathing during long sleep may increase the indoor carbon dioxide concentration, causing a headache and the like. Furthermore, especially in new constructions, the concentration of formaldehyde and VOC generated from building materials such as carpets, flooring, cloths, etc. may rise to levels that cannot be achieved by neglecting ventilation in the initial stage after moving in. Moreover, when furniture other than building materials is purchased or curtains are cleaned, these concentrations may increase.
[0004]
In order to prevent these problems, a ventilation system that ventilates for 24 hours with a low air volume using a ventilator such as a bathroom or a washroom in an apartment house in recent years (for example, Japanese Patent Application No. 9-9 No. 353134 and Japanese Patent Application No. 10-88329, both unpublished) are attracting attention. These ventilation systems, as illustrated in FIG. 5, comprises a fan 1 can be operated at all times ventilation rate N _l and ordinary ventilation speed N _h, high winds volume when using the bathroom lavatory or toilet (usually ventilation rate) It is ventilated and usually ventilated for 24 hours with a low air volume (normal ventilation speed) with low operating noise and low electricity bill. This is because in modern apartment houses (for example, condominiums) that have become denser, even if the airflow is low, continuous ventilation provides a flow of ventilation not only in the bathroom and washroom, but also in the entire dwelling unit. This is because it has become clear. In FIG. 5, 2a, 2b, and 2c are switches for switching the normal ventilation air volume, for switching on and off the normal ventilation, and for switching the normal ventilation air volume, respectively, and 3 is a step-control motor.
[0005]
[Problems to be solved by the invention]
On the other hand, ventilation devices such as bathrooms, washrooms, and toilets in existing apartment houses generally have a simple structure in which a ventilation fan is operated by an ON-OFF switch. This type of ventilator has a large air volume but is noisy, so it is not normally operated continuously and is switched off after being activated only during use. However, due to the recent health orientation, when replacing a ventilation fan such as a failure or a remodeling, it has become desirable to replace the ventilation device that can be applied to the 24-hour ventilation system described above.
[0006]
However, if the existing ventilation device is replaced with the ventilation device for 24-hour ventilation illustrated in FIG. 5, the following problem occurs particularly in a housing complex such as an apartment.
{Circle around (1)} One is a problem of wiring modification. In typical apartments, as shown schematically in Fig. 6, the interior corridors, washrooms, toilets, etc. have double ceilings due to the need for piping space for ventilation ducts, and the ceiling part is relatively easy However, the partition wall 4 that partitions each room is in a state in which it is difficult to modify the wiring because the wooden shaft running vertically and horizontally in the wall obstructs. In this figure, 5 is a unit bath and 6 is an existing ventilation device installed above the unit bath.
By the way, as shown in FIG. 7, the wiring of the existing ventilation device is provided with ON-OFF ventilation switches 7a and 7b in the middle of the power supply wiring to the ventilation device 6 (for example, the bathroom and the toilet). Wiring for operating the ventilator 6 by opening and closing. Therefore, if the ventilator 6 is replaced with a new 24-hour ventilator (see Fig. 5) and the wiring is simply connected, if the contacts are opened at the toilet or toilet switch 7a, 7b, the power source 8 Is not supplied and the ventilation device cannot be operated for 24 hours. Moreover, even if it tries to redo these wiring, since a part of wiring is wired in the wall and the existing ventilation switches 7a and 7b are provided on the wall surface, the partition wall 4 is broken and newly installed. Renovation is impossible unless major construction work is performed.
[0007]
(2) One problem is that, as illustrated in FIG. 8, in the conventional ventilation device 6, there are many examples in which an anchor is provided on a concrete ceiling slab and is fixed by two-point suspension from the anchor by suspension bolts 6a. . In this case, since the ventilation device for 24-hour ventilation is a box shape that requires four-point suspension, a new anchor for bolts should be formed on the concrete ceiling slab using a small space in the ceiling. However, there are many problems that the ventilator cannot be operated by breaking the ceiling of the bathroom.
[0008]
The present invention has been developed to solve the above-described problems. In other words, the main purpose of the present invention is to replace the existing ventilation device without carrying out a major construction, to make the conventional ventilation operation by utilizing the existing wiring and switch as it is, and to perform the desired 24-hour ventilation. An object of the present invention is to provide a ventilator for remodeling that can be performed reliably. Furthermore, another object is to provide a renovation ventilator that can be installed easily and reliably using the existing two suspension bolts as they are, without providing a new suspension bolt anchor on the ceiling slab.

The contacts 3 to 5 of the motor 12 are connected to the three contacts (for example, strong, medium, and weak) of the normal ventilation air volume changeover switch 21a of the remote controller 21 via terminals T1 to T3, respectively. The switch 21a can be set to an OFF state that is not connected to any of the three contacts.
[0017]
The constant ventilation air volume changeover switch 13 is a manual switch for setting the air volume in the normal ventilation, and is switched in advance to either 1 or 2 according to the ventilation area (for example, the size of the apartment).
The mode switching relay 14 is composed of an electromagnetic solenoid R1 and its contact point 1a. When the mode switching switch 21b of the remote control 21 is turned ON / OFF, the contact point 1a is turned ON / OFF, and the power supply to the contact points 1 and 2 of the motor 12 is turned ON.
