Further, the impeller device 120 includes a body 122a formed by laminating a plurality of plate members; And upper and lower covers 122b and 122c covering upper and lower parts of the body 122a. It is understood that the upper and lower covers may be omitted, if necessary.

In the meantime, the term housing according to the present invention includes the body 122a and the upper and lower covers 122b and 122c, and when the upper and lower covers 122b and 122c are omitted, the housing includes only the body 122a do. Such a configuration is not a central theme of the present invention, and a person skilled in the art will be able to variously realize such a configuration, and a detailed description thereof will be omitted.

3 is an exploded perspective view of an impeller apparatus 120 according to an embodiment of the present invention, which includes an impeller 121; A hollow support base 123 connecting the housing 122 with the impeller 121 to the control box and connecting the impeller to the control box, And an axis 124 extending in the longitudinal direction from the impeller 121 and connecting the motor provided in the controller with the impeller 121.

The housing 122 includes a housing body 122a formed by stacking a plurality of plate members of the same shape and upper and lower covers 122b and 122c covering upper and lower portions of the housing body 122a .

Each of the plate members (and the cover) is thinner than the conventional body, so that it is possible to manufacture the plate member (and the cover) through processes such as punching of a plate member, sheet metal plate, As a result, the burden on the mold production cost is reduced. Further, it becomes easy to change the shape as necessary.

Here, the body 122a has an impeller receiving space surrounded by a wall of the body formed by vertically stacking a plurality of plate members 122a1 to 122a3 having the same shape, and the opened upper and lower surfaces thereof And covered with upper and lower covers 122b and 122c.

In the drawing, the plate members of the plurality of plate members 122a1 to 122a3 are shown to be formed in the same shape, but basically, only the positions of the accommodating spaces formed in each plate member and / It should be understood that they may be formed symmetrically and other portions may be formed differently. Accordingly, the shape of the impeller apparatus shown in a substantially pentagonal shape can be variously changed.

On the other hand, as the fastening holes for fastening are formed on the body 122a formed by laminating the plurality of plate materials 122a1 to 122a3 and the upper and lower covers 122b and 122c, the state in which the impeller 121 is placed in the inner housing space , They can be fastened together by fastening means such as bolts and nuts to be integrated. Meanwhile, in the present invention, it is to be understood that the fastening means can be not only a bolt nut, but also various methods known to those skilled in the art in the current technology of screwing, welding, adhesion and the like.

The upper cover 122b has an outlet 122b1 communicating with the protruding space formed on the plate members 122a1 through 122a3 and the accommodation space in which the impeller is located. A support opening 122b2 for communicating with the support 123 is formed at the substantially center of the upper cover so that the support 123 is coupled to the upper cover 122b, 124 are screwed, for example, to the impeller 121 located in the receiving space. On the other hand, the connection between the support table 123 and the support opening 122b2 can be achieved by welding or screwing.

Also, at least one inlet 123a is formed on the support 123 in the vicinity of the top cover.

When the heater 110 and the impeller device 120 are filled with water at a predetermined height through the control box 130 after the water is filled in the bathtub 200, The heated water is introduced into the support base through the inlet 123a of the support base 123a and is then introduced into the interior of the body 122a through the inlet 123a of the support base 123a as the impeller 121 of the impeller device rotates, And then flows into the bathtub through the protruding space and the outlet 122b1, and as the operation is repeated, the water in the bathtub is circulated continuously.

On the other hand, during this operation, the water that flows into the support table 123 does not move to the receiving space in which the impeller is located, but rather rises, for example, by pulsation, along the hollow inside the support, There is a risk of flowing into the control box through the connection part of the control box 124. In order to prevent this, in the present invention, the auxiliary outlet 123b is formed on the support 123 so as to be spaced apart from the inlet 123a. When the auxiliary outlet 123b is formed, the water rising through the support can be discharged again into the bathtub, so that damage to the control box due to the inflow of water can be prevented.

The wings 121b have an area defined by the width w1 and the length and the impeller 121 having the wings 121b having an increased width as the number of laminations of the plurality of plate materials 122a1 to 122a3 increases, The capacity of the impeller device can be increased.

Conversely, as the number of laminations of the plurality of plate members 122a1 to 122a3 decreases, the capacity of the impeller apparatus can be reduced by replacing the impeller 121 having the blade 121b having a reduced width. On the other hand, w1 + work tolerance has a relation of = W.

On the other hand, in Fig. 4, the blades 121b having different areas, for example, are detachably attached to the disk portion 121a by fastening means such as bolts. However, in one embodiment, a plurality of impellers attached by welding to blades having different areas are welded. Depending on the increase or decrease in the number of laminations of the plurality of plate members 122a1 to 122a3, an impeller may be selectively used .

Hereinafter, an assembling method according to an example of the impeller apparatus will be described.

First, the plurality of plate materials 122a1 to 122a3 and the upper and lower covers 122b and c are manufactured through a sheet metal, for example.

The impeller 121 is fixed on the shaft 123 with the upper cover 122b fixed to the support base 123 through the support opening 122b2.

The plurality of plate members are stacked to form a body 122a in which a housing space for housing the impeller 121 is formed.

Then, the lower cover 122c is attached to the lower surface of the body 122a to close the lower surface of the accommodation space.

The lower cover 122c and the body 122a are coupled to the upper cover by using fastening means in a state where the impeller 121 coupled to the motor via the shaft is positioned in the accommodating space.

Meanwhile, the subject of the assembling method according to the present invention is that a plurality of plate materials and covers are manufactured through sheet metal and the manufactured members are laminated, and various assembling methods can be adopted within a range where such a theme is not changed to be.
