본 고안은 화장실 또는 주방에 환풍기가 없는 장소에 주로 설치사용하도록 구성된 환풍기 이동장치에 관한 것으로, 화장실 또는 주방의 창문을 통하여 내실의 공기가 단시간에 환기될수 있도록 하기 위하여 창문을 열은 다음 열린창문 앞에 환풍기가 이동정치되도록 하고 환풍기의 전원스위치를 온시켜 환풍기를 가동하게 하므로 환풍기 없는 장소에 유효한 환풍기 이용과 간단한 설치수단으로 이용되게 할 목적에 있다.The present invention relates to a ventilator moving device configured to be installed and used mainly in a place without a ventilator in a bathroom or a kitchen. The window of the toilet or the kitchen is opened in front of an open window in order to allow air in the room to be ventilated in a short time. It is intended to be used as a simple means of installation and effective use of the ventilator in a place without a ventilator because the ventilator is moved to the stationary position and the power switch of the ventilator is turned on to operate the ventilator.

일반적으로 환풍기는 화장실 또는 주방에 창문과는 별개로 실내의 벽면에 환풍구멍을 뚫어서 외부로 실내공기를 배출시키기 위한 환풍기를 환풍구멍에 고정식으로 설치되어 있다.Generally, the fan is fixedly installed in the vent hole to exhaust the indoor air to the outside by drilling a vent hole in the wall of the room separately from the window in the bathroom or kitchen.

그러나 이는 환풍기를 가동시킬 때 환기되고 가동되지 않을시에는 역으로 외부의 바람이 환풍구멍 및 환풍기를 통해 실내로 불필요한 외부공기가 실내로 유입되므로 환풍기의 불가동시 환풍구멍을 닫아주는 개폐문을 별개로 설치 이용한 것도 있었다. 그러므로 이런 기존의 설치수단으로 환풍기가 없는 곳에 설치이용하기 위하여 벽면을 뚫어서 환풍기를 새로히 설치 이용하기란 설치수단에 있어 어려움이 있고 또 고가의 수공비를 요구하므로 이미 설치되어 있는 창문을 열어서 환기되도록 하고 있었으나 단시간에 환기되지 못한 결함이 있었다. 또 창문은 필요에 따라 열고 닫아야 하므로 창문에 고정식 환풍기의 설치는 구조적으로 어려운 문제점이 있었다.However, this is ventilated when the fan is started and when the fan is not running, the external wind flows into the room through the vent hole and the fan, and the door is closed separately to close the vent hole when the fan is inactive. Some used. Therefore, to install and use a new fan by drilling a wall in order to use it where there is no ventilator, the existing installation means has difficulty in installation means and requires expensive manual expenses. There was a defect that was not ventilated in a short time. In addition, because the window must be opened and closed as needed, the installation of a fixed fan in the window had a difficult structural problem.

본 고안은 종래와 같은 결함과 문제점을 감안하여 환풍기가 없는 화장실 및 주방에 창문을 이용하여 가장 적당하고 간단한 구성으로 설치이용 될수 있도록 한 것이다.The present invention is to allow the installation and use in the most suitable and simple configuration using a window in the bathroom and kitchen without a vent in view of the defects and problems as in the prior art.

본 고안은 창문 및 실내벽의 위치에 따라서 환풍기 설치에 따르는 이동수단을 3가지 방식으로 구성하였다. The present invention is constructed in three ways by means of moving the ventilation fan according to the position of the window and the interior wall.

첫째는 도 1, 도 2, 도 3에 도시한 바와같이 창문의 측벽면에 고정시킨 힌지에 삽입 장착시킨

Figure 112005071438529-utm00005
형 회동봉에다 공기흡입식의 환풍기 뒷면주위에 고정시킨 고정테를 연결편으로 연결 고정설치하여서 환풍기가 회전이동되게 하였다.First, as shown in Fig. 1, Fig. 2, and Fig. 3 is inserted into the hinge fixed to the side wall surface of the window
Figure 112005071438529-utm00005
The fan was rotated by attaching and fixing the fixed frame connected to the back of the air suction-type fan by the connecting piece.

둘째는 도 4, 도 5에 도시한 바와같이 창문의 상부 벽면에 양측의 힌지에

Figure 112005071438529-utm00006
자형 회동봉을 설치하여 환풍기 뒷면에 고정시킨 고정테와 연결편으로 회동봉을 연결 고정하므로 환풍기가 상부쪽으로 회전 이동되도록 하였다.Second, as shown in Figs. 4 and 5, hinges on both sides of the upper wall of the window are shown.
Figure 112005071438529-utm00006
The rotating rod was connected by a fixed frame and a connecting piece fixed to the back of the fan by installing a shaped rotating rod, so that the fan was rotated upward.

셋째는 도 6, 도 7에 도시한 바와같이 창문의 양측벽면에 레일봉을 상하에 고정축수로 고정설치하고 환풍기 뒷면에 고정시킨 고정테 상하에 한쌍의 걸고리를 각각 고정하여서 환풍기를 걸고리로서 레일봉에 걸어 연결설치하므로 환풍기가 좌, 우이동되게 하였다.Third, as shown in Figs. 6 and 7, the rail rods are fixed on both sides of the window with fixed shafts at the top and bottom, and a pair of hooks are fixed at the top and bottom of the fixed frame fixed to the rear side of the fan, respectively. The fan was moved to the left and right as it was installed on the wall.

이런 구성은 환풍기 사용시와 사용않을시에 이동시키게 함으로 평소 창문이용에 지장이 없고 또 환풍기 이용시에는 창문을 열고 환풍기를 이동설치하여 이용토록 하므로 이용에 편리하고 또 이는 설치수단이 간편하고 누구나 손쉽게 설치이용 할수 있으므로 유효하고 편리하도록 함에 있다.This configuration is convenient for use because it moves the fan when not in use and does not interfere with the usual window use, and when the fan is used, it opens the window and moves and installs the fan to use it. It is to make it effective and convenient.

본 고안의 구성과 작용은 다음과 같다.The construction and operation of the present invention are as follows.
