Description

  The present invention relates to a cooler such as a fan or a ceiling fan that is installed on a ceiling or a wall in a living room and is used to reduce the temperature of the sensible temperature due to direct wind or to circulate indoor air.

  Conventionally, this type of cool air blower has an impeller and a motor enclosed in a base that serves as a pedestal, and air circulates in such a manner as to blow out horizontally from an annular air blower provided at the top of the base. Household blowers that produce air flow are also known. (For example, refer to Patent Document 1).

  Hereinafter, the blower will be described with reference to FIGS. 10 and 11.

  FIG. 10 is a projection view of the blower assembly 100 as viewed from the front, and FIG. 11 is a cross-sectional projection view of the blower assembly 100. The blower assembly 100 has an annular nozzle 101 that defines a central opening 102. A motor 122 that creates an air flow through the annular nozzle 101 is disposed within the base 116 along with the motor housing 126. Further, the impeller (impeller) 130 is connected to a rotating shaft extending outward from the motor 122, and the motor 122 in which the diffuser 132 is positioned downstream of the impeller 130 is connected to an electrical connection unit and a power source. A plurality of selection buttons 120 allow the user to operate the blower assembly 100.

  In the above configuration, the above-described blower assembly 100 operates as follows. The motor 122 is driven by the user appropriately selecting from a plurality of selection buttons 120. Thus, the motor 122 is activated and air is drawn 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 air flow that exits the outlet 136 of the diffuser 132 and the exhaust portion of the impeller 130 is divided into two air flows that travel 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 throttling creates pressure in the system. The air flow thus created overcomes the pressure produced by the restriction and the air flow exits through the outlet 144 as the primary air flow. The primary air flow is concentrated or focused toward the user depending on the arrangement of the guide portion 148. The secondary air flow is generated by entrainment of air from the outside environment, particularly from the area around the outlet 144 and around the outer edge of the annular nozzle 101. This secondary air flow passes through the central opening 102 where there is a total air flow that mixes with the primary air flow and is discharged forward from the blower assembly 100.

  In such a conventional cool air blower, because the nozzle is closed in an annular shape, the air flow blown from here has a high-speed wind speed distribution in a closed annular shape. The wind speed distribution can be widened to obtain a cool wind feeling over a wide range. However, when the nozzle blowing direction is widened with the conventional configuration, the air in the ring is attracted from the back of the annular outlet. Since there is a limit to the amount of air attracted in the configuration that is sent forward, the inside of the ring becomes negative pressure, and it is not possible to have a wide wind speed distribution against the negative pressure. There was a problem that it could not be obtained (FIG. 4 described later).

  Then, this invention solves the said conventional subject, and it aims at providing the air blower which can acquire a cool wind feeling in a wide range.

  In order to achieve this object, the present invention includes a high-pressure air generating part of a box containing an impeller and an electric motor, and a plurality of blowing parts having a slit nozzle that blows out high-pressure air to generate an air flow in one direction. A blower comprising a connection part as a ventilation path for the blowing part and the high-pressure air generating part, wherein a slit nozzle of each blowing part is connected to the shaft on an arbitrary axis and a plane perpendicular thereto. It is arranged in an annular shape so as to surround and provide a space therebetween, and the blowing direction of the slit nozzle is outward with respect to the shaft, wherein the blowing portion is an arbitrary shaft, A plurality of slit nozzles are annularly arranged on a plane perpendicular to this so as to surround and surround the shaft, and the slit nozzle blowing direction is outward with respect to the shaft. Also a blower , And the thereby is to achieve the intended purpose.

  According to the present invention, the feeling of anxiety due to contact can be eliminated by enclosing the impeller, and a feeling of cool breeze can be obtained in a wide range by an appropriate nozzle configuration, thereby improving comfort.
