Description

[Detailed Description of the Invention] This invention relates to a range ventilation fan that is mainly used for local ventilation in the kitchen.

This type of ventilation fan described above is basically configured such that the ventilation fan body is assembled inside a hood-shaped blower case, and is connected to an exhaust duct to exhaust the dirty air introduced into the blower case to the outdoors. There is.
However, with conventional types, it is often difficult to connect to the exhaust duct when the installation space is specified by a hanging cabinet, etc. In such cases, the connecting part of the exhaust duct can be clearly seen from inside the room, It often spoils the aesthetic appearance.

This invention not only facilitates connection with the exhaust duct and maintenance of the relevant part, but also fits well into the space specified by hanging cabinets, etc., and also has an air intake structure for general ventilation, contributing to improving the aesthetic appearance of the kitchen. The purpose of the present invention is to provide a ventilation fan for a microwave oven.

Next, the configuration of the present invention will be specifically explained based on an embodiment shown in the drawings.

The range ventilation fan as an application example of the present invention shown in the figure is a ventilation fan equipped with a fan casing 2 on the back side, which is the installation side, inside a hood-shaped blower case 1 with an open bottom and a front side expanded toward the bottom. The main body 3 is assembled, and the suction port 2A formed by the fan casing 2 of the ventilation fan main body 3 forms a bell mouth 2B inside the blower case 1 and opens toward the front, and the discharge port 2C forms a bell mouth 2B inside the blower case 1. The exhaust chamber 4 is connected to an exhaust chamber 4 that extends through the top plate of the exhaust chamber and projects above the top plate. The opening at the bottom of the blower case 1 is an intake port that introduces smoke and steam rising from the cooking area, etc., and is equipped with a removable filter 5.
is installed. In addition to this intake port, the blower case 1 has a slit-shaped intake hole 6 formed in the front for taking in indoor air, so that the air taken in through the intake hole 6 performs general ventilation as well as local ventilation. It's summery. As shown in Fig. 1, the exhaust chamber 4 installed on the top plate of the blower case 1 is located slightly toward the rear of the center of the top plate and extends all around within the planar area of the top plate. It is installed with plenty of room to cross. This exhaust chamber 4 is formed with a duct connection port that can be opened as needed on the back and both sides, and the duct connection port 7 that is opened as necessary is connected to the indoor side of the exhaust duct 8 that connects to the outdoors. A connecting flange 9 is fitted, with which the ends can be connected in a fitted manner. Blower case 1
In addition to the above-mentioned exhaust chamber 4, a box-shaped intake chamber 10 is attached to the top plate of the vehicle. The intake chamber 10 has a side surface and a front surface that correspond to the blower case 1 and are formed to have dimensions that are almost flush with each other, an intake hole 11 is formed in the front surface, and the bottom surface communicates with the inside of the blower case 1 through a communication hole. . The appearance of the intake chamber 10 is designed to harmonize with the blower case 1 in terms of design, and is designed to look like a part of the blower case 1. The intake chamber 10 and the blower case 1 are hinged with a hinge 12 at a matching portion on the front side thereof,
The intake chamber 10 can thereby be rotated until its front surface comes into contact with the front surface of the blower case 1. The intake chamber 10 is the blower case 1
When in the upper position, the exhaust chamber 4 is covered from the front by the intake chamber 10, and from the front is covered by the intake chamber 1.
Only 0 is visible.

As shown in FIG.
Even in a small space defined by the wall 15, the back side of the blower case 1 can be fixed to the wall 15 with screws or the like through the intake port at the bottom, and the exhaust duct 8 passing through the wall 15 can be used to exhaust air. It can be fitted into the connection flange 9 of the chamber 4 and communicated with the duct connection port 7. That is, the connection operation between the exhaust duct 8 and the exhaust chamber 4 is performed by connecting the exhaust duct 8 and the exhaust chamber 4.
This can be done from the outside by making use of the front, rear, right and left gaps of the exhaust chamber 4 that appear by rotating the blower case 0 forward, and there is no need to disassemble the structure inside the blower case 1. However, since the exhaust chamber 4 protrudes upward at the center of the top plate portion of the blower case 1, even if the top surface of the exhaust chamber 4 is mounted close to the ceiling plate 13, the above-mentioned exhaust duct 8 cannot be connected. A gap that is useful for operation may be visible from the front, and the connecting portion of the exhaust duct 8 may be exposed into the room. Therefore, in the case of this example, it is equivalent to raising the intake chamber 10, which has a standing dimension approximately equal to the height dimension of the exhaust chamber 4, and extending the front of the blower case 1 and part of the left and right side surfaces upward. This makes it possible to cover the front of the exhaust chamber 4 with the intake chamber 10. The intake chamber 10 is formed with an intake hole 11 on its front surface, and the dirty air that tends to accumulate on the ceiling side is introduced from the intake chamber 10 into the blower case 1 and exhausted to the outside. Ventilation can be carried out. The presence of the intake chamber 10 eliminates unevenness in the space in the kitchen, making the area around the range ventilation fan neat and clean, thereby enhancing the aesthetic appearance of the kitchen.

In the figure, reference numeral 16 indicates a fan motor fixed to the back surface of the blower case 1 by means of mounting legs 17, and 18 indicates a switchbox.

As is clear from the above description of the embodiments, the range ventilation fan of the present invention has an exhaust chamber protruding from the hood-shaped blower case with multiple connection ports for connecting exhaust ducts, and The outlet of the ventilation fan body configured in the interior faces this exhaust chamber, and the front upper end of the blower case covers the front of the exhaust chamber, and the intake chamber, which is connected to the blower case at the bottom, is routed to the front of the blower case. Since it is hinged so that it can move, the communication between the exhaust duct and the exhaust chamber can be made from the outside without disassembling the inside of the blower case even after the blower case is installed. The components on the blower case, such as the exhaust chamber, can be covered with the intake chamber so that they cannot be seen from the indoor side, improving the aesthetic appearance of the kitchen. It can also contribute to the improvement of
Furthermore, it is also possible to take in dirty air from the ceiling side through the intake chamber to perform general ventilation.
