Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a blower, and more specifically, it is used in a general household, etc., and is capable of generating cool air from a blower fan and warm air from a blower fan and heater by switching between them. This article relates to improvement of the louver part of the blower.

(B) Conventional technology A conventional blower has a main body case with an air outlet on the front, and the air outlet is movable up and down to adjust the direction of the air coming out of the outlet up and down. A type of louver is known that includes a louver and a louver link that is attached to the louver so as to be movable up and down and moves up and down to rotate the louver.

Inside the main case of this blower are 2. A blower fan, a motor that drives the blower fan, a main switch that operates the motor, and a heater that heats the air are provided. Further, a heater switch and a switching knob for operating the heater are provided on the outside of the blower. This switching knob turns the heater switch on and off when the main switch is turned on, in order to obtain hot or cool air.

In such a blower, the louver is rotated by manually operating a louver link connected to the louver when changing the direction of the air coming out of the outlet into upward, horizontally forward, or downward directions.

(c) Problems to be Solved by the Invention In the above-mentioned blower, since warm air rises, when efficiently heating a room in cold weather,
It was necessary to generate warm air by pointing the louver downward. In other words, if you forget to set the louvers facing down, or if you have them facing down in advance but the louvers end up facing horizontally or upwards due to a child's play or vibration, heating efficiency will deteriorate. There was a problem.

This invention has been made in view of the above-mentioned circumstances, and its purpose is to provide an air blower in which the louvers face downward when hot air is blown out.

(d) Means and operation for solving the problem This invention includes a main body case having an air outlet on the front surface, and a main body case that is arranged in front of the air outlet so as to be movable up and down so that the direction of the air coming out from the air outlet can be adjusted up and down. A louver to be adjusted, a louver link that is attached to the louver so as to be movable up and down and moves up and down to rotate the louver, a blower fan disposed within the main body case, and a heater disposed within the main body case; It includes a heater switch that operates the heater, and a switching means that can turn the heater switch on and off to generate hot air or cool air when the blower fan is activated, and further, the switching means is configured to generate warm air. This blower includes a louver operation section that moves a louver link downward in conjunction with a switching operation, thereby holding the louver in a downward position.

That is, in the blower according to the present invention, when blowing hot air, the direction of the louver is checked, and if the louver is not facing downward, the louver is held downward by moving the louver link downward by hand. Instead of the conventional system, a louver operating section is provided as a switching means for obtaining hot air or cool air. Then, the louver link is moved downward in conjunction with the switching operation to generate warm air, and the louver is held downward.

The means for switching between warm air and cool air is equipped with a vertical or horizontal shaft that has a part for turning on and off the heater switch, and a switching knob or switching lever that is attached to this shaft and rotates the shaft. Things such as te are used.

As the louver operating portion formed on the switching means, a triangular rib that is vertically protruding from the end of a shaft that is a part of the switching means is used. For example, when the switching knob as a switching means is turned to the hot air side, the tip of the louver link that was in contact with the slope of the rib slides on the slope of the rib, and the louver link moves downward. shall be.

By turning the switching knob, the tip of the louver link pressed by the sloped surface of the rib moves downward along the sloped surface.

Then, when the switching knob is switched to the hot air side, the louver link reaches the lowest position and the louver is held downward.

Thus, by operating the switching means toward the hot air generation side, it becomes possible to blow out the hot air downward without manual operation of the louver.

(E) Example The present invention will be described in detail below based on an example shown in the drawings. Note that this invention is not limited to this.

In FIGS. 1 to 4, a motor 1 of a blower F is screwed to a left air kite 3 via a motor supporter 2, and connected to a shaft portion of an axial blower fan 4. As shown in FIGS.

The left air guide 3 covers the outer periphery of the blower fan 4, rectifies the wind generated by the rotation of the blower fan 4, and directs it to the air outlet 19.
This is the book that will lead you to.

This left air guide 3 is provided with a heater accommodating portion 3a for accommodating a heater 5. When the hot air/cool air switching knob 6 is turned to the warm air side, a heater link 16 connected to the switching knob 6 rotates 90 degrees clockwise. Due to this rotation of the heater link 16, the heater 5 connected to the heater link 16 comes out of the heater accommodating part 3a, and the second
Covers the air outlet 19 in front of the left air guide 3 as shown by the two-dot chain line in the figure. This allows warm air to blow out towards the moe.

Reference numeral 7 denotes a right air guide, which together with the left air guide 3 forms a ventilation path from the suction port to the outlet 19. This right air guide 7 has the function of preventing wind from escaping to the rear.

In front of these air guide units (left air guide 3 and right air guide 7), a panel unit 11
is provided. The panel unit 11 has a wind outlet 19, and ten horizontal louvers 8 that are vertically movable to guide the wind in the vertical direction, a louver link 9 that vertically moves the horizontal louvers 8, and a wind blower. It has five vertical louvers lO that guide the left and right direction. The panel unit 11 and the air guide unit are connected to the front case 1.
2, rear case 13, stand base 14
, and covered by the switch case 15.

Next, the operation of this ventilation IP will be explained.

When the switching knob 6 is turned to the hot air side, the heater 5 rotates via the heater link 16 attached to the switching knob 6 and comes out to the air outlet 19. The outer peripheral surface of the heater link 16 has three partially protruding cam-shaped parts (16a, 1
6b, 16c) Yes.

+6a is a cam-shaped portion for a heater switch I8 that operates the heater 5. 16b is a heater switching spring 1 that switches the heater 5 to a position where warm air or cool air is generated.
It is a cam-shaped part that comes into contact with 7.

Reference numeral 16c is a cam-shaped portion consisting of a triangular forward rib, which is closely related to the present invention, and will be explained below based on FIG. 4.

When the louver link 9 is held at the uppermost position, the tip 9a of the louver link 9 is close to the lower inclined surface of the triangular prism rib 16c. At this time, a cool breeze is generated. Here, when the switching knob 6 is turned 90 degrees to the hot air generation side (right side), the tip 9a of the louver link 9 adjacent to the triangular prism rib 16c is pushed by the lower slope of the rib 16c, and as shown in FIG. Move downward as shown by the arrow. Therefore, when the switching knob 6 is switched to the hot air generation position, the louver link 9
is fixed in a depressed position.

The tip end 9a of the louver link 9 is spherical in order to smooth the sliding of the louver link 9. Furthermore, silicone grease or the like is applied to the ribs 16c to improve sliding.

With the above structure, when a cool breeze is generated, the position of the horizontal louver 8 can be adjusted upward or downward.

(F) Effects of the Invention According to this invention, since the louver is configured to be held downward when hot air is generated, the hot air is blown downward and efficient heating can be performed at any time.

In addition, inefficient heating is no longer caused by forgetting to turn the louver downward, or by causing the louver to turn upward due to a child's play or vibration.

Furthermore, since the louver is lowered in conjunction with switching the switch knob to the hot air side, there is no need to manually lower the louver when hot air is generated.

In addition, the louvers can be adjusted up and down freely when a cool breeze occurs.
