Abstract

PURPOSE:To make possible drying, heating, ventilation, and air supply of two rooms by means of a unit of apparatus of low cost, by providing on a partition plate a damper which selectively changes over the air flow to either a first room or a second room. CONSTITUTION:A second discharge port 5 is closed by means of a damper 9 and a heater 8 and a fan 3 are energized. Air is drawn from a bathroom A and the outside 1 to the fan 3, heated with a heater 8 and discharged through a first discharge port 4 into the bathroom A, where said bath room A is utilized as a drying rom usingheated air. An opening 12 on a partition plate 11 is closed by means of the damper 9 and the heater 8 and the fan 3 are energized. Then, air in the bathroom A and the outside 1 is drawn to the fan 3, heated with the heater 8, and dischaged through a second discharge port 5 into a toilet room B, where said toilet room is heated with heated air. As described above, ventilation, drying, heating and air supplying of two rooms can be performed by means of a unit of ventilation apparatus by changing over a damper.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ventilation device that is attached to the ceiling of a bathroom, washroom, or toilet and performs ventilation, drying, heating, ventilation, etc. of the bathroom, washroom, or toilet. It is.

BACKGROUND OF THE INVENTION Conventionally, this type of ventilation system has generally had a configuration as shown in FIG. 2 or 3, although no specific literature can be cited.

In other words, the one shown in Fig. 2 uses a blower 10 to blow the air in the room.
3, the air is sucked into the ventilator main body 101 through the suction port 102, some of the air is heated by the heater 104, and circulated into the room through the second discharge port 106, and the other air is sucked into the ventilator body 101 through the first discharge port 105. Exhaust the air to the outside. Since a part of the air taken in in this way is exhausted to the outside E through the first discharge port 105, the inside of the room becomes negative pressure, and the air from the outside E is supplied to the room through the air supply port 107'i. I care. Moreover, the air in the room C is exhausted to the outside E through the discharge port 109 by the blower 108 regardless of the ventilation device 101.

Furthermore, in the case shown in Fig. 3, when drying or heating room G, the first electric damper 1 in the discharge path to room F is used.
21 is closed, and the second electric damper 122 in the discharge path to the room G is opened. In this state, the blower 120 blows the air from the room G through the third duct 115, and the air from the outside H through the fourth duct 117.
0, heated by the heater 119, and discharged into the room G through the second duct 113. In addition, since air is supplied from the outdoor H, the pressure inside the room G becomes ■, and the exhaust port 12
3, the air in the room G is exhausted to the outside H. Also,
When drying or heating room F, use the first electric damper 1.
By opening the damper 21 and closing the second electric damper 122, the room F can be dried and heated.

Ventilation and air blowing can be achieved by operating the blower 120i without powering on the heater 119.

Problems to be Solved by the Invention This conventional configuration has the following drawbacks.

(1) Since one equipment is required for each room, the equipment cost is relatively high, and each room requires space to install the equipment.

(2) Since duct piping is required for each piece of equipment, construction costs are relatively high and duct space is also required.

(3) In the example shown in Fig. 3, equipment costs for the electric damper are required, making it relatively expensive.

(4) In the example shown in FIG. 3, a control circuit for interlocking the electric damper is required.

The present invention solves these problems by reducing equipment costs and drying and heating two rooms with one unit.

The object of the present invention is to provide a ventilation device that can perform ventilation and blowing.

Means for Solving the Problems In order to solve this problem, the present invention provides a blower having a heater at its discharge port inside the main body of the ventilation device, and the discharge side of the blower is connected to a first room communicating with the first room. a second discharge port that communicates with the second chamber via a side duct from a surface other than the first discharge port; and a partition plate that partitions the first discharge port and the second discharge port. , the first part provided on this partition plate
The air blower has a damper that selects air blowing to either the room or the second room, and the air blower suction side has a first suction port that communicates with the first room, and a damper that is connected to the duct from a surface other than the first suction port. The ventilator has a second suction port that communicates with the outside through the ventilator.

Function: In this configuration, the damper can select the air to be sent to either the first room or the second room to dry, heat, ventilate, or blow air to either the first room or the second room. It becomes possible.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIG. In FIG. 1, reference numeral 1 denotes a ventilation device main body that houses a blower 3 attached to a partition plate 2 that partitions the blower discharge side and the blower suction side, and a first outlet 4 that communicates the blower discharge side with the bathroom A. , a second discharge port 5 that communicates the blower discharge side and the washroom B via a duct, and the blower suction side and the bathroom A.
A first suction port 6 that communicates with A damper 9 is installed at either location B to select the type of air blowing. The bathroom A and the outdoor room I are communicated with each other through an exhaust port 1o, and a first discharge port and a second discharge port are separated by a partition plate 11.

This partition plate 11 is provided with an opening 12.

When drying the bathroom Ai in the upper dC1 configuration, a changeover switch (not shown) closes the second discharge port 6 with the damper 9 and energizes the heater 8 and the blower 3. In this state, air is sucked into the blower 3 from the bathroom A and the outside I, heated by the heater 8, and discharged into the bathroom A through the first outlet 4. This heated air blows the inside of the bathroom A. It can be used as a drying room.

Here, some air is supplied to bathroom A from outside I, and the pressure inside bathroom A becomes ■, so a part of the air discharged into bathroom A is exhausted to outside I through exhaust port 1o. Ru.

Furthermore, when taking a bath in the bathroom, the heated air can be used as preliminary heating before taking a bath in winter.

In addition, the blower 3 is not powered on to the heater 8.
By running the fan I for ventilation, and in the summer
It can be used as an air blower instead of a T machine.

Next, when heating the washroom B, the damper 9 closes the opening 12 of the partition plate 11, and the heater 8 and the blower 3 are energized. In this state, air from the bathroom A and outside I is sucked into the blower 3, heated by the heater 8, and discharged into the washroom B through the outlet 6 of the snore 2. can be heated.

Note that when the heater 8 is not powered on, the blower 3
By operating the fan, it can be used as a ventilation fan in the summer.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, by switching dampers, one ventilation device can ventilate, dry, heat, and blow air into two rooms, and the equipment per room can be reduced. This has the effect of reducing costs, duct construction costs, etc.
