Description

The present invention relates to a blower device such as an electric fan, which is installed indoors or outdoors and is used for reducing the sensible temperature by direct airflow and circulating air in the room.

Conventionally, in this type of blower, an impeller and a motor are enclosed in a base that serves as a pedestal, and air is circulated by blowing out from a ring-shaped blower provided at the upper part of the base in a horizontal direction with the floor surface. And a household blower that produces an air flow is known (see, for example, Patent Document 1).

Hereinafter, the blower will be described with reference to FIGS. 8 and 9.

FIG. 8 shows a front view of the blower assembly 100, and FIG. 9 shows a cross-sectional view of a main part of the blower assembly 100. The blower assembly 100 has an annular nozzle 101 that defines a central opening 102. Inside the base 116 of the blower assembly 100, a blower device that generates an air flow through the annular nozzle 101 is arranged. In the blower, the impeller (impeller) 130 is connected to a rotary shaft extending outward from the motor 122 arranged together with the motor housing 126, and the diffuser 132 is positioned downstream of the impeller 130. The motor 122 is connected to an electrical connection and a power source (not shown), and the user can operate the blower assembly 100 by the plurality of selection buttons 120 shown in FIG.

With the above configuration, the blower assembly 100 operates as follows.

When the user selects a favorite button from the plurality of selection buttons 120 and the motor 122 is activated, air is sucked into the blower assembly 100 through the air inlet 124. Air flows through the outer casing 118 to the inlet 134 of the impeller 130. The airflow exiting the outlet 136 of the diffuser 132 and the exhaust section of the impeller 130 is divided into two airflows traveling in opposite directions through the internal passage 110. The air flow is throttled as it enters the mouth 112 and is further throttled at the outlet 144 of the mouth 112. This throttle creates pressure in the annular nozzle 101.

The airflow thus created overcomes the pressure generated by the throttle and exits through outlet 144 as a primary airflow. The primary airflow is focused or focused towards the user by the arrangement of the guide portion 148. The secondary airflow is generated by suction of air from the external environment, in particular the region around the outlet 144 and around the outer edge of the annular nozzle 101. This secondary airflow passes through the central opening 102, where a total airflow that mixes with the primary airflow and is discharged forward from the blower assembly 100 is generated.

As a result, when the fluctuating airflow from the lower outlet has a higher airflow velocity than the steady airflow from the upper outlet, the surrounding air is attracted in the direction of the airflow with a higher airflow velocity, so that the air blown from the blower The flow goes downward on the fluctuating airflow side. In addition, when the fluctuating airflow from the lower outlet is smaller than the steady airflow from the upper outlet, the surrounding air is attracted in the direction of higher airflow velocity, so the flow of air blown from the blower. Will go upward on the steady airflow side. Therefore, when the user wants to circulate the air in the room without being exposed to a direct strong wind, a more natural wind is provided by blowing a fluctuating air flow with a change in velocity or wind direction to the user.

As a result, a steady air flow with a high wind speed is blown from the upper part, and not from the lower part. It is also possible to suppress unevenness.

Further, in the blower device according to the present invention, the control unit may be controlled to blow the same fluctuating wind from the upper outlet and the lower outlet so as to have different phases as the blown airflow. As a result, both the upper and lower parts blow out fluctuating airflow, so you can feel comfortable and more natural without feeling unpleasant stress such as a decrease in body temperature due to long-term exposure to steady wind. Can be obtained and air circulation in the room can be promoted.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. It should be noted that the following embodiments are examples that embody the present invention and do not limit the technical scope of the present invention. Further, in order to avoid duplication, the same parts are designated by the same reference numerals throughout the drawings, and the second and subsequent explanations are omitted.

(Embodiment 1)
First, the blower 1 according to the first embodiment of the present invention will be described with reference to FIGS . 1, 2, and 3. FIG. 1 is a perspective view of a blower device 1 installed in a living room, FIG. 2 is a detailed perspective view of the blower device 1, and FIG. 3 is a front view of the blower device.

The blower device 1 blows airflow toward the living room, and as shown in FIG. 1, a plurality of pillars 13 of equal length (6 in the present embodiment) standing up from a floor surface which is one wall surface of the living room. Pieces) are provided. Each pillar 13 has a rectangular cross-sectional shape, and the upper portions of the plurality of pillars 13 are connected by a top plate 32. The upper part of the pillar 13 may not be connected by the top plate 32, and the gaps between the plurality of pillars 13 may be opened at the upper part. Further, the pillar 13 may be projected downward from the ceiling surface. Further, the pillars 13 may have different lengths and cross-sectional shapes.

As shown in FIG. 2, of the six pillars 13, the upper blower pillar 13a is arranged in the central two, and two lower blowout pillars 13a are arranged on the outside of the upper blowout pillar 13a, for a total of four lower blowout pillars 13b. Is placed. The upper blowout pillar 13a blows out air in a direction perpendicular to the standing direction. On the other hand, the lower outlet pillar 13b is provided with an outlet 5b for blowing air in a direction perpendicular to the standing direction on the housing 2 side of the outlet 5a of the upper outlet pillar 13a.

In the upper outlet pillar 13a, an outlet 5a is provided above the central portion in the height direction from the central portion to one end (hereinafter referred to as an upper end) different from the housing 2, and in the lower outlet pillar 13b, the outlet 5a is provided. An outlet 5b is provided below the central portion in the height direction from the central portion to the end portion on the housing 2 side (hereinafter referred to as the lower end portion). Here, the outlet 5a and the outlet 5b are the upper half and the lower half of the pillar 13, respectively, but the outlet 5a and the outlet 5b may have dimensions of more than half of the pillar 13 so as to overlap the central portion. That is, the outlet 5a may have a dimension of not more than half from the upper end of the upper outlet pillar 13a, and the outlet 5b may have a dimension of more than half from the lower end of the lower outlet pillar 13b. The upper outlet pillar 13a and the lower outlet pillar 13b are provided with a gap as an attracting air passage 6 between the adjacent pillars 13 and the same plane so that the outlets 5a and the outlet 5b are in the same direction. It is placed on top. Here, the same plane means a state in which the side surfaces of all the pillars 13 having the outlets 5a and 5b and the side surfaces facing the outlets 5a and the outlets 5b are aligned and arranged in a straight line.

Further, as shown in FIG. 2, the housing 2 is provided with a suction port 7 for taking in air on a side surface facing the air outlet 5a and the air outlet 5b. Further, as shown in FIG. 3, three chambers 10a, 10b, and 10c are provided on the inner upper side of the housing 2 downstream of the outlet of each fan 8 (fan 8a, fan 8b, fan 8c) . Each chamber 10 communicates with one fan 8 and two pillars 13. In the present embodiment, the combination of one motor, one fan, one chamber, and two pillars is set as one blower unit, but a configuration in which each is combined one by one and a plurality of each component are used. It may be configured as a combination of.

Further, although the space in which the fan 8 and the motor 9 are arranged is regarded as one space, a partition is provided inside the housing 2 to provide a plurality of spaces, for example, in the case of the present embodiment, one for each of the fan and the motor. It may be divided into three spaces.

Further, in the housing 2, a control unit 11 for controlling the air flow blown from the air outlet is arranged on the side surface of the housing 2. In order to control the airflow blown from the upper blowout pillar 13a and the lower blowout pillar 13b, the control unit 11 has a motor 9b of the fan 8b of the upper blowout pillar 13a, a motor 9a of the lower blowout pillar 13b, and a motor 9a of the lower blowout pillar 13b. An electric signal for controlling the number of revolutions is transmitted to 9c. These electric signals are transmitted to the motors 9a, motors 9b, and motors 9c via information arithmetic processing such as a microprocessor and a memory provided on the circuit board constituting the control unit 11.

Next, the operation of the blower 1 will be described with reference to FIGS. 3, 4, and 5. 4 and 5 show side views of the blower 1. The control unit 11 blows the airflow from the upper blower pillar 13a and the blown airflow from the lower blower pillar 13b under different airflow controls. When the control unit 11 drives the fans 8a, the fans 8c, the motors 9a, and the motors 9c that communicate with the lower blowout pillar 13b, the fans 8a and the fans 8c rotate, and the indoor air flows from the suction port 7 to the housing 2. It is taken inside. The taken-in air passes through the fans 8a and 8c and flows into the chambers 10a and 10c. The air flowing into the chambers 10a and 10c is diverted into two lower blowout pillars 13b in the chambers 10a and 10c, passes through the inside of the lower blowout pillars 13b, and is blown out from the outlet 5b into the indoor space. The air flow becomes 14.

The control unit 11 blows the airflow from the upper blowout pillar 13a and the blown airflow from the lower blowout pillar 13b under different airflow controls. The different airflows are airflows having different wind speeds and volumes of airflows sent from the upper outlet 5a and the lower outlet 5b. Further, in the case of a fluctuating airflow in which a weak airflow that blows a small amount of air and a strong airflow that blows a large amount of air alternately are generated, it is possible to blow different airflows by making the phases of the fluctuations different. By appropriately setting the rotation speeds of the respective motors 9a and 9c, different airflows can be sent from the upper outlet 5a and the lower outlet 5b. In the present embodiment, separate fans 8a and 8c are provided in order to blow different airflows from the upper outlet 5a and the lower outlet 5b, but even if it is one fan, the upper outlet is provided. By providing ducts in 5a and the lower outlet 5b, it is possible to blow different airflows.

The air outside the attracting air passage 6 and the outermost lower blowing pillar 13b shown in FIG. 3 is attracted by the blowing airflow 14 to become the attracting airflow 15. The blown airflow 14 and the attracted airflow 15 merge in front of the blowing direction of the blowing device 1, and a surface airflow having a substantially uniform wind speed can be blown over a wide range.

Further, as shown in FIG. 3, when the control unit 11 drives the fan 8b and the motor 9b that communicate with the upper blowout pillar 13a, the fan 8b rotates, and the indoor air flows from the suction port 7 to the inside of the housing 2. Is taken in by. The taken-in air passes through the fan 8b and flows into the chamber 10b. The air flowing into the chamber 10b is diverted from the chamber 10b to the two upper blowout pillars 13a, passes through the inside of the upper blowout pillars 13a, and is blown out from the outlet 5a into the indoor space to become the blowout airflow 14. The airflow outside the attracting air passage 6 and the outermost lower blowing pillar 13b is attracted by the blowing airflow 14, and becomes the attracting airflow 15. The blown airflow 14 and the attracted airflow 15 are merged in front of the blowing direction of the blowing device 1, and a surface airflow having a substantially uniform wind speed can be blown over a wide range even above the blowing device 1.

As shown in FIG. 4, the control unit 11 blows out a steady airflow 22 from the upper outlet 5a and a fluctuating airflow 23 from the lower outlet 5b.

According to such a configuration, as shown in FIG. 4A , the fluctuating airflow 23 and the attracted airflow 15 from the lower outlet 5b are more airflows than the steady airflow 22 and the attracted airflow 15 from the upper outlet 5a. When the speed is high, the surrounding air is attracted in the direction of the high air flow speed, so that the air flow 24 blown from the blower device 1 goes downward on the fluctuating air flow 23 side.

Further, as shown in FIG. 4B , when the fluctuation airflow 23 and the attracted airflow 15 from the lower outlet 5b are smaller than the steady airflow 22 and the attracted airflow 15 from the upper outlet 5a, the airflow is airflow. Since the surrounding air is attracted in the direction of higher speed, the air flow 24 blown from the blower device 1 is directed upward on the steady air flow 22 side. Further, since the fluctuating airflow 23 from the lower outlet 5b changes its velocity with time, the air flow 24 changes its direction upward or downward in this way.

By controlling the motor by changing the air volume from each of the upper and lower blowout pillars 13 to blow air, it is possible to blow air to obtain a cool feeling and to circulate the air in the room, which is preferred by the user each time. There is an effect. For example, in spring or autumn, when it is desired to circulate the air in the room without being exposed to a direct strong wind, the airflow can be controlled as shown in FIG. 4 (b). By controlling the airflow as shown in FIG. 4B , it is possible to provide a natural wind to the sitting user by the fluctuating airflow 23 having a speed change. On the other hand, the upper blowing pillar can promote the air circulation in the room by blowing the steady air flow 22 of the steady wind. Therefore, the user can obtain a comfortable fluctuating wind without feeling unpleasant stress such as a decrease in body temperature by being exposed to a steady wind for a long time, and can promote air circulation in the room.

The control unit 11 may control that the fluctuating airflow 23 is always slower or faster than the steady airflow 22. As a result, the air flow 24 blown from the blower device 1 always goes downward or upward.

As shown in FIG. 5A, the control unit 11 may control to blow out the steady airflow 22 from the upper outlet 5a and not to blow air from the lower outlet 5b. As a result, when the blower device 1 is operated, for example, in winter, when the control unit 11 drives the motor 9b of the fan 8b communicating with the upper blowout pillar 13a, the fan 8b rotates. As a result, the indoor air is taken into the inside of the housing 2 from the suction port 7. The taken-in air passes through the fan 8b and flows into the chamber 10b. The air that has flowed into the chamber 10b is diverted into the two upper blowout pillars 5a in the chamber 10b, passes through the inside of the upper blowout pillar 5a, and becomes the blowout airflow 14 that is blown out from the upper blowout port 5a into the indoor space. Blowout airflow 14
As a result, the air in the attracting air passage 6 formed between the two upper blowing pillars 13a and the attracting air passage 6 formed between the upper blowing pillar 13a and the adjacent lower blowing pillar 13b is attracted. The attracting airflow is 15. Therefore, since the steady airflow 22 is blown from the upper part and not from the lower part, the temperature in the room is uneven by more efficiently circulating the air in the room and stirring the air without directly hitting the user. It is also possible to suppress.

Further, as shown in FIGS. 5 (b) and 5 (c), the control unit 11 may control to blow the same fluctuating airflow 23 from the upper outlet 5a and the lower outlet 5b so as to have different phases. .. Further, as shown in FIG. 5B, when the fluctuation airflow 23 and the attracted airflow 15 from the lower outlet 5b are smaller than the fluctuation airflow 23 and the attracted airflow 15 from the upper outlet 5a, the airflow is airflow. The surrounding air is drawn in the direction of the high-velocity airflow. Therefore, the air flow 24 blown from the blower device 1 heads upward on the fluctuation airflow 23 side from the upper air outlet 5a.

Further, as shown in FIG. 5 (c), when the fluctuation airflow 23 and the attracted airflow 15 from the lower outlet 5b are larger than the fluctuation airflow 23 and the attracted airflow 15 from the upper outlet 5a, the airflow is airflow. Since the surrounding air is attracted in the direction of higher speed, the air flow 24 blown from the blower device 1 goes downward on the fluctuating airflow 23 side of the lower air outlet 5b. Further, since each fluctuation airflow 23 changes its velocity with time, the air flow 24 thus changes its direction and velocity upward and downward. As a result, the fluctuation airflow 23 having a different phase and velocity is blown out from both the upper outlet 5a and the lower outlet 5b, so that unpleasant stress such as a decrease in body temperature due to long-term exposure to steady wind is felt. A comfortable fluctuating wind can be obtained without any need, and indoor air circulation can be promoted. Further, the air moving in the room by blowing out the fluctuating airflow 23 from both the upper outlet 5a and the lower outlet 5b makes it possible for the user to feel more natural.

A flowchart is shown in FIG. 6, and a control method will be described below. When the user turns on the operation switch in S1 shown in FIG. 6, the power is turned on to the blower device 1 , and the user selects the current season (S2), for example, with the remote controller of the blower device 1. When a season is selected, the microcomputer determines the ventilation mode (S3, S4) according to the season, issues instructions to the motors 8a, 8b, and 8c, and the ventilation is started. For example, if the season is determined to be winter, the air is blown in the upper / constant airflow mode of S5 (an example of the first airflow control), and if the season is determined to be summer, both the upper and lower sides of S6 are fluctuating winds. If it is determined that the airflow is in the mode and the season is other than winter or summer, the airflow is performed in the upper steady / lower fluctuation wind mode (an example of the first airflow control) of S7. Further, when the user selects, for example, to stop the remote controller (S8), all the motors are stopped in S9, and the ventilation is also stopped in S10. As a result, the user can easily change the ventilation mode with a remote controller or the like according to each season, and can spend time in a more comfortable indoor space.

By providing a temperature sensor, a notch control that can change the blowing speed depending on the room temperature or the like may be installed. As a result, the user can obtain a more comfortable feeling by making the wind speed relatively faster or slower when the temperature in the room is high and low.

Although the season is selected by the remote controller, the current temperature, the airflow mode, and the like may be assigned to the judgment criteria of S3 and S4, not limited to the season.

As shown in FIG. 7, the blower device 1 also has a configuration in which a fan motor 18 composed of an impeller for generating high-pressure air and a motor for driving the impeller is provided inside the underfloor 40. good. An outlet 19 for blowing out high-pressure air generated by the fan motor 18 is provided in one direction perpendicular to the direction in which the pillar 13 is erected. The air outlet 19 is provided on the side surface on the short side of the pillar 13, and the inside of the pillar 13 is provided with a duct 20 for guiding the high-pressure air generated by the fan motor 18 to the air outlet 19. The duct 20 has at least the same number as the pillars 13. Chambers 21a and 21b for distributing high-pressure air to the duct 20 of each nozzle 13 are provided under the floor 40 between the fan motor 18 and the duct 20.

Further, as shown in FIG. 7, the high-pressure air generated by the fan motor 18 is guided to the chamber 21a through the flow path 12a for the upper blowout pillar 13a under the floor 40, and is diverted to each duct 20. .. Similarly, the high-pressure air generated by the fan motor 18 is guided to the chamber 21b via the flow path 12b for the lower blowout pillar 13b under the floor 40, and is diverted to each duct 20. According to such a configuration, when the blower device 1 is operated by a command from the control unit 11, the fan motor 18 is driven and the impeller rotates to generate high-pressure air, and a plurality of chambers 21a and 21b are generated. The air flow is divided into the duct 20 of the above, and air is blown from the upper air outlet 5a and the lower air outlet 5b, and each air can be blown by the first air flow control. The fan motor 18 and the chamber are provided under the floor 40, but the present invention is not limited to this, and the fan motor 18 and the chamber may be provided in whole or in part, for example, in the ceiling.

Further, in the present embodiment, all the pillars 13 are provided in parallel with the blowing direction, but the direction and the number of pillars 13 are not particularly limited. However, the wide-angle lens may be provided so that the air blowing direction is separated from the central pillar 13 toward the pillar 13 provided on the outside from the center of the pillar 13. As a result, the phenomenon that the airflow gathers in the central portion of the blower device 1 can be suppressed up to a certain distance from the blower device 1, and the range of the wind can be widened.

Further, in the present embodiment, the number of pillars 13 is 6, but there is no particular limitation on these design values. However, the user can appropriately change the width of the blower 1 and the number of pillars 13 depending on the space and design.

The blower and the blower according to the present invention are useful as a blower in which the user can appropriately change the range of the wind.
