Description

TECHNICAL FIELD The present invention relates to an air cleaner with an electric warmer incorporating an electric heater as a heat source.

[Conventional technology]

FIG. 3 is a cross-sectional view showing a conventional stationary air purifier with an electric warmer, in which (1) is an upper case covering the main body operation switch and the control board, and (2) is a fan (3).
And a motor (4) with a blower attached to the middle case, (5) an air intake panel with an air inlet, (6) a filter capable of collecting dust of several microns, and (7) a lower air outlet. A lower air passage for guiding air to (8), (9) is a lower case, (13) is a rear case, (15) is an electric heater, and (16) is a base for fixing the main body.

Next, the operation will be described. When the fan (3) is rotated by driving the motor (4), air is sucked from the intake port of the intake panel (5). The sucked air passes through a filter (6) provided inside the intake panel (5), whereby dust contained in the air is collected by the filter (6). The purified air passes through the lower outlet air passage (7), the electric heater (15), and is blown out from the lower outlet (8) while cooling the motor (4). At this time, when the operation is used as heating, the electric heater (15) is energized to warm the air and blow it out as warm air when the air passes between the electric heaters (15). Also, when the operation is dedicated to air cleaning, the air passes between the electric heaters (15), but at that time, the electric heaters (15) are blown out without being energized.

[Problems to be Solved by the Invention]

Since the conventional air purifier with an electric air blower is configured as described above, even when it is used exclusively for air cleaning, it is necessary to blow out the clean air from the lower part, and therefore the dust accumulated on the floor is taken up. However, there is a problem in that efficient air cleaning cannot be performed.

The present invention has been made to solve the above problems, and an object thereof is to obtain an air purifier with an electric warm air blower that can efficiently use heating and air purification.

[Means for solving the problem]

An air purifier with an electric warmer according to the present invention has a main body provided with an intake port on the front face, a first blowout port near the upper back face, and a second blowout port on the lower front face. A blower provided inside the main body to face the intake port and blows air downward, a filter provided between the blower and the intake port, and a lower end provided in the main body is opened to a lower part inside the main body. An upper outlet air passage that extends upward and communicates with the first outlet, and an electric heater that is provided in the main body and is equipped with one end open to the lower inside of the main body and the other end communicates with the second outlet. And a wind-path switching device that is formed in an arcuate shape in the lower part of the main body and is rotatively displaced to select either the upper-flow air passage or the lower-flow air passage. is there.

[Action]

When the air purifier with an electric warm air blower according to the present invention is used exclusively for air purifying by the air passage switching device, it purifies air upward from the first outlet provided at the upper portion of the main body. Further, when used as heating, the purified air is discharged from the second outlet provided in the lower part of the main body, so that efficient air cleaning and heating can be performed.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a side sectional view of the air purifier with a stationary electric air blower according to an embodiment of the present invention when heating, and FIG. 2 is a side sectional view of the air purifier dedicated to air cleaning. In the figure,
(1) is an upper case that covers the main body operation switch and the control board, (2) is a middle case (5) having a fan composed of a fan (3) and a motor (4), and an intake panel having an intake port, (6) is a filter capable of collecting dust of several microns, (7) is a lower outlet air duct that guides air to the lower outlet (8), (9) is a lower case (10), and a microswitch (1
1) is attached to the upper casing to form an air duct for introducing air to the fan casing and the upper outlet (12), (13) is the rear case, and (14) is the air passage switching device, which has an arc shape. The center of a circle forming an arc is pivotally attached to the main body and is provided in the lower part of the main body, and is rotationally displaced to provide either the upper air passage (10) or the lower air passage (7). Is to be selected.
(15) is an electric heater in the lower air passage (7),
Semiconductor heaters, nichrome heaters, etc. (16) is a base for supporting the main body.

Next, the operation will be described. When the fan (3) is rotated by driving the motor (4), air is sucked from the intake port of the intake panel (5). The suctioned air is collected by the filter (6) provided inside the intake panel (5) to collect dust contained in the air up to several microns. The purified air once flows downward while cooling the motor (4). At this time, when the operation is heating, as shown in FIG. 1, the air passage switching device (14) is closed so as to prevent the outflow of air into the upper air passage (10). At this time, the micro switch (11) provided below the upper blowing air passage (10) is pushed by the air passage switching device (14) to turn on the electric heater (15). The purified air passes through the lower blowing air passage (7) and the electric heater (15). At this time,
The air is warmed, and is blown as warm air from the lower outlet (8) to warm the room above the floor. When the operation is used only for air cleaning, the air passage switching device (14) is hermetically sealed to prevent air from flowing out to the lower air passage (7) as shown in Fig. 2. The purified air is guided to (10). At this time, the micro switch (11) provided below the upper air passage (10) is opened, so that the electric heater (15) is not energized. The air guided to the upper outlet air duct (10) is blown out from the upper outlet (12) and circulates in the room, so that the air in the room can be cleaned without directly blowing air to the human body.

Although the electric heater (15) is energized by the airflow switching device (14) in the above-described embodiment, the electric heater (1
The power of 5) may be turned on and off with an operation button by incorporating a circuit in the control board. The upper outlet is located right above the main body in FIGS. 1 and 2, but may be on the upper side of the main body, and the same effect as in the above-described embodiment can be obtained.

Further, although the upper outlet (12) is directed upward as in the above-mentioned embodiment, it may be directed obliquely upward.

〔The invention's effect〕

As described above, according to the air purifier with an electric warmer of the present invention, the air outlet is changed by the air passage switching device which is formed in a circular arc shape and rotates, so that it is used exclusively for air cleaning. In this case, since the purified air is discharged upward from the first outlet provided near the rear surface of the upper part of the main body, the air can circulate in the room without directly hitting the human body and an efficient air cleaning action can be obtained. . Further, when used as heating, since the purified air is discharged from the second outlet provided in the lower part of the main body, efficient air cleaning and heating can be performed.
