Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention is a device that injects water into a water tank built into the body of an appliance such as a cooling fan or humidifier from outside the body. Related to water injection devices used for things.

(Prior Art) Cooling fans, humidifiers, and the like that have a built-in water tank consume a lot of water and require frequent replenishment of water into the water tank, so there is a need to make this task easier. Therefore, water can be poured directly into the water tank from the opening provided in the outer wall of the main body without having to take the water tank in or out.

For example, in the device disclosed in Japanese Patent Publication No. 56-36337, water can be poured into a water tank by providing a water injection container that can be horizontally rotated to open and close the window hole provided in the main body of the device. I'm letting you do it.

In addition, the device disclosed in Publication of Utility Model Publication No. 62-38165 is the same as the above case in that an opening is provided on the side of the outer box so that it can be opened and closed by a door, but the door has a lower end side. It has a single-opening structure that is pivotally mounted and can move up and down, and in the open state, a water injection guide that opens corresponding to the upper opening of the built-in water tank is formed on the inner side of the door to enable water injection. It is.

These have the effect that when the water injection window hole is opened, a part of the water injection guide protrudes outside the main body, making it easy to inject water from the outside. However, in order to obtain a water filling guide function for each, it is a prerequisite that the above-mentioned members are positioned above the upper edge of the opening of the built-in water tank. In addition, all of the above have a structure in which the water injection window opening in the side wall of the main body is integrated and also serves as the door body for opening and closing, so that the door body and the water injection guide can be used in common. In addition, there is also the restriction that the water injection window must be located above the water tank.

This makes it impossible to check the water level directly from the side of the tank, so it is necessary to look into the tank from above through the window hole to check the water level during water replenishment work. Not only is it difficult to confirm, but also the above-mentioned
With the method disclosed in Publication No. 38165, it is almost impossible to confirm this, and there is also the problem that a separate window must be provided for confirming the water level.

As a countermeasure for this, a large window hole is made in the side wall of the main unit that faces the entire length of the water tank in the vertical and depth direction, and a door body that opens on one side is installed in this window hole, and a water injection guide is integrated into the upper part of the window hole. For example, if the configuration disclosed in Japanese Utility Model Publication No. 57-31234 is used, the side wall surface of the water tank faces the window hole, so
Even with this configuration, the above-mentioned disadvantages can theoretically be solved by making the water tank transparent or by installing a separate water level gauge.

(Problem to be solved by the invention) However, similar to the conventional configuration described above, in order to operate in conjunction with the above-mentioned one by cooperating,
In addition to integrating the door body and the water injection guide, this water injection guide is particularly advantageous because the door body has a single-opening configuration, so the water injection guide has an L-shaped bent shape, which is integrated with the door body. The mold would be complicated if it were to be constructed as one part using a mold, so in this case, the two parts mentioned above had to be molded separately and then combined in post-processing. The number of assembly steps involved in the work increases, leading to increased costs.

Furthermore, even when periodically cleaning the inside of the aquarium, the bottom of the water filling guide and the opening edge of the aquarium (humidifying container) are always in contact with each other, regardless of whether the door body is opened or closed. It is unavoidable that the work of separating and connecting the water injection guide and the water tank becomes complicated, and improvements in these areas have been desired.

This invention not only makes it easy to check the water level during water injection, but also eliminates the need to integrate the water injection guide body and the door body, which is the case with conventional configurations that are subject to manufacturing and assembly constraints. While the water injection guide body remains separated, a part of the water injection guide body can be moved in and out through the water injection opening that opens in the main body in conjunction with the opening and closing of the door body, providing a water injection device that is highly practical in use. The purpose is to

[Structure of the device] (Means for solving the problem) The present invention has a water injection guide body, a water injection opening covered with a door body that can be opened and closed on the outer wall of the device body, and a water injection guide body built into the main body. In a device that opens the door body and injects water into the water tank from outside the main body via the water injection guide, the water injection opening provided on the outer wall of the main body is connected to the water level of the water tank. facing the side wall surface in the horizontal direction, opening in the vertical direction, and disposing a door body that can be opened and closed outward on one side by pivoting one side end side or the bottom end side to this opening, Above water injection guide body,
One end is positioned above the water tank as a pivot part, and the other end extends outward, and its tip part moves up and down with the pivot part as a pivot point so as to face the water injection opening. The tip of the other end of this water injection guide body is brought into contact with the back surface of the door body, and when the door body is closed, it is rotated upwardly, and when it is opened, it is rotated downwardly by its own weight. This is a water injection device in which the water injection guide body is associated with the opening/closing operation of a door body so as to be freely retractable from the opening of the door body.

(Function) The present invention is equipped with the above-mentioned configuration means, so that when the door is closed, the water injection guide body rotates upward with its tip abutting the back surface of the door, and the main body When the door body is opened to inject water, the object stored inside the tank is released from contact with the tip part in conjunction with the opening operation, and the pivot point on one end side on the water tank is used as a fulcrum. The other end is allowed to rotate downward due to its own weight, and its tip protrudes outward from the water injection opening, allowing water to be poured from the outside of the main body.

Further, the water injection opening has a large opening facing the side wall surface of the water storage tank, and the tip of the water injection guide protruding from the opening is also positioned above the opening and stopped. Therefore, the water level can be directly viewed from the side of the water tank through the opening from at least the bottom of the guide body, and thereby the water filling operation can be performed while checking the water level.

After the water injection is completed, when the door body is closed, the tip of the water injection guide body comes into contact with the back side of the door body, and is pushed upward while resisting its own weight and stored and held within the main body.

In this way, the door body and the water injection guide body can be operated in conjunction with each other without daring to integrate them.

(Example) Hereinafter, an example of this invention will be described with reference to drawings in which it is used in a cooling fan.

In FIG. 3, an outer wall 2 forming the instrument body 1
A vertically open air outlet 3 is provided on the front side of the air blower, and a vertical louver 4 for changing the left and right air direction is provided in the air outlet 3.

Further, a back cover 6 with an open suction port 5 is detachably attached to the rear side of the main body 1. Inside the air outlet 3, a heating element 7 is disposed facing the vertical louver 4 side, and behind it a blowing fan 9 connected to a blowing drive motor 8 is placed. External air sucked from the suction port 5 by the fan 9 undergoes heat exchange within the main body 1 as will be described later, and then flows through the air outlet 3 to the main body 1.
A ventilation passage 10 for circulation to exhaust air to the outside is provided in the main body 1.
It is beginning to form within itself.

Furthermore, a water storage tank 11 formed of a transparent material is built in the lower part of the device body 1.
A part of the lower side of an endless belt-shaped water absorption filter 12, which is arranged to face the suction port 5 and cross the ventilation path 10, is inserted into the interior and immersed in the water in the water storage tank 11. It is becoming more and more common. Further, the water absorption filter is stretched between a driving roller 13 and a driven roller 14 which are arranged above and below, and when cold air is supplied, the driving roller 13
A filter drive motor 15 connected to the filter drive motor 15 is driven to draw out the water-absorbing filter 12 containing water from the water storage tank 11 to the ventilation passage 10 and return it to the water in the water storage tank 11 for circulation. Ru. The water impregnated in the water absorption filter 12 comes into contact with the air sucked into the blower fan 9 while passing through the blower passage 10 and is evaporated. The air that has been taken away and whose temperature has decreased is discharged from the blower outlet 3 as cold air.

The above-mentioned heating element 7 is provided so that warm air or warm humidified air can be supplied instead of the cold air, and the desired function can be obtained by selecting a switching means (not shown) in conjunction with cold air blowing. It's getting old.

Next, to explain the water supply-related configuration which is the main part of the invention, on the water tank 11 mentioned above, there is a top lid 16 that covers the entire opening thereof, and its outer peripheral edge 16a is fitted with the top end of the water tank 11. At the same time, the water absorption filter 12 is attached to the upper lid 16.
An insertion port 17 and a water injection port 18 through which the lower end of the water injection port 18 is inserted are respectively opened.

Further, this water inlet 18 has an opening close to the inner surface of the outer wall 2 of the main body 1, and a support wall 19 that stands upward in an inverted U-shape and surrounds the three sides thereof is integrally formed. , this supporting wall 19
The one-end pivot portion 21 of the water injection guide body 20, which has support shafts 20a, 20a protruding from the outside of the base, is positioned and held in place. As shown in FIGS. 1 and 2, the water injection guide body 20 is formed in the shape of a gutter and has an opening 20b at one end located between the inner walls of the support wall 19, so that the water injection guide body 20 is provided above the water storage tank 11 with an opening 20b. The support shaft 2 is made to face through the opening 18 and has its other end extended outward.
0a and 20a are used as rotational fulcrums to freely move up and down, and the other end side is tilted diagonally upward so that its own weight, which is constantly biased to rotate downward, is used for water injection as described later. The extending tip portion 20c is brought into contact with the back surface of the door body 23 that closes the opening 22 of the door body 23, and the two are in a relationship in which they can be freely moved toward and away from each other by opening and closing the door body 23.

The above-mentioned water injection port 1 is provided on the outer wall 2 of the appliance body 1.
The water injection opening 22 is provided adjacent to the water injection guide body 8 and is covered by the door body 23 in an openable and closable manner. The upper end is slightly upward facing the extending tip 20c which is rotated and tilted to the side, and the lower end is opened vertically as the lower half facing the side wall surface of the water tank 11. The width of the opening may be at least slightly larger than the width of the water injection guide body 20, but in the illustrated example, the opening is relatively wide so that the water level can be checked from both sides of the water injection guide body 20. ing.

The water injection opening 22 is pivoted to the upper and lower ends of the door body 23 as pivot parts 21 so as to be opened to one side in the lateral direction.

Therefore, when the door body 23 is opened, as shown in FIG. It is untied and rotated downward, and is projected outward through the water injection opening 22, so that water can be poured into the water tank 11.

That is, when the tip 20c of the water injection guide body 20 projects outward from the opening 22, the back surface of the bottom side of the water injection guide body 20 comes into contact with the outer peripheral edge 16a of the top lid 16, and the pivot portion 21 Since it is stopped and held at an inclined angle with one end side opening 20b facing downward, the water flows smoothly when water is poured.

Also, the water level in the water tank 11 can be checked by opening the water injection opening 22 by opening the door body 23.
is largely opened in the vertical direction across the lower half facing the side wall surface of the water tank 11.
2, the state of the water can be easily checked while pouring water, and there is no possibility of water overflowing during pouring.

On the other hand, after completing water injection, it is sufficient to simply close the door body 23, and in the middle of closing, the rear surface of the door body 23 and the extending tip portion 2 on the other end side of the water injection guide body 20
0c is brought into contact with the body 1 again, and the water injection guide body 20 is pushed in while rotating upward against its own weight.
It can be stored inside.

As shown in the third figure, an insertion/removal port 25 covered with a lid 24 through which the water storage tank 11 can be inserted/removed is provided on the outer wall 2 facing the rear side of the water storage tank 11. When the inside of the tank 11 needs to be cleaned, the lid 24 is opened and the water tank 11 can be pulled out from the insertion/removal port 25.
In this case, after first removing the above-mentioned back cover 6 and pulling out the water absorption filter 12, the water tank 11 can be pulled out from the insertion/removal port 25. At this time, the water filling guide body 20 is attached to the top lid 16 of the water tank 11, so if the water filling guide body 20 is tilted inward so that it does not become an obstacle when drawing out the water tank 11, the top lid 16 along with the water tank 11
6 can be withdrawn at the same time. Moreover, the installation after cleaning can be done by simply inserting the top cover 16 into the normal position from the insertion/removal port 25 in the reverse order as described above, and by simply turning the water injection guide body 20 outward, the tip of the Since the portion 20c is brought into contact with the back surface of the door body 23 described above, the insertion and removal of the water tank 11 can be done by simply changing the direction of the water injection guide body 20, and no special adjustment work such as positioning is required.

In addition, in the above-described embodiment, the door body 23 for opening and closing the water injection opening 22 is pivoted so as to open one side in the lateral direction, but both sides of the lower end are pivoted so that the door body 23 opens one side downward. Even if it is a configuration, there is no problem.

[Effects of the invention] As described in detail above, according to the invention, one end of the water injection guide body is positioned on the water tank as a pivot joint, and the extending tip of the other end is positioned on the water tank with the pivot joint as a rotation fulcrum. Since the turning power is applied to the water injection guide by its own weight, the extending tip of the water injection guide can be attached to the back side of the door without integrating the door and the water injection guide as in the conventional structure. By just making contact, the water injection guide body can be moved in and out of the water injection opening in conjunction with the opening and closing operations of the door body, which not only eliminates the need for connection work for the above-mentioned interlocking operation. , all of the conventional restrictions associated with integration have disappeared,
The water injection device is highly practical in use, as the opening for water injection can be opened opposite the side of the water tank, and the water level can be easily checked through this opening during water injection work. Can be provided.
