Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a floor-standing fan coil unit, and in particular,
The present invention relates to a structure for mounting an air filter on a casing.

[Prior art and its problems]

Conventionally, a fan coil unit is often used in a place requiring a large number of air conditioners on the room side, such as a hospital or a hotel, because of the ease of individual control and the high degree of freedom in arrangement and installation. The fan coil unit has various advantages as described above, but on the other hand, it also has the disadvantage of requiring many maintenance inspections such as cleaning the air filter, clogging of valves, air vents, and drain pipes. There is. In particular, regarding the cleaning of the filter, it is necessary to remove the filter from the casing first, but this operation itself has a problem that it is a very troublesome work. This means that this operation is performed almost by hand, and that the filter should not be dropped on the floor or come into contact with the casing so as not to scatter dust adhering to the filter during the removal work. This is due to things such as having to be handled carefully. In addition, when actually cleaning the filter, for example, in a place where there are many places where the unit is installed, it is common to remove the filter from the unit body and then collect these in a cleaning place. In addition to the very troublesome work of attaching and detaching the filter itself, the filter must be transported, and for this reason, a considerable amount of time is spent on the cleaning work. In addition, when trying to operate the fan coil unit even during cleaning work, more troublesome work such as mounting a spare filter is required, but operation is often performed with the filter removed, and There is a risk that the fins may be clogged and the unit may be adversely affected. On the other hand, the cleaning work is often carried out at the place where the unit is installed, but even in that case, the attachment and detachment operation of the filter is still a troublesome work. Further, as a concrete method of the cleaning work that is usually performed, basically, vacuum suction is performed on the filter surface by using an electric vacuum cleaner or the like. It is performed by holding it with one hand so that it stands on the floor, and applying the suction port of the vacuum cleaner to the filter surface with the other hand. In such a work mode, especially when a large fan coil unit and a large filter are used, the work is extremely difficult to perform.

[The purpose of the device]

The present invention was created in order to effectively solve the above-mentioned problems of the prior art. Therefore, an object of the present invention is to provide a fan coil unit having such a filter mounting structure that allows the filter to be taken out from the casing by a simple operation and can be easily mounted on the casing when cleaning the filter. To do.

[Means for Solving the Problems]

The fan coil unit according to the present invention is configured as follows to achieve the above object. That is, the fan filter unit is a floor-standing type fan coil unit in which the periphery of the filter medium is held by a frame member, and an air filter formed in a substantially plate shape is arranged on the lower surface of the casing. It is held by a free filter holding member and is attached to the casing via the filter holding member. The filter holding member is provided at a position projecting to the outside of the casing from a first position in which the filter surface of the air filter is directed downward to a second position in which the filter surface is directed forward or upward. The rotation is allowed and the second
It is provided with a support means capable of supporting the position of the air filter in that position.

[Action]

In the floor-standing fan coil unit having the above configuration, the attachment / detachment operation for cleaning the air filter is performed as follows. First, when removing the air filter from the casing,
Pull out not the air filter itself, but the filter holding member to the outside of the casing. Since the air filter is held by the filter holding member and attached to the casing, the air filter is pulled out to the outside of the casing while being held by the filter holding member by this operation.
However, in this operation, since the filter surface is simply pulled out from the casing, the filter surface in that state remains as it was when it was mounted on the casing, that is, the filter surface was directed downward or toward the floor surface, and cleaning was performed. Inadequate to do the work. Therefore, as the next operation, in order to turn the downward facing filter surface forward or upward,
Turn the air filter to turn it over. This rotation is
The process may be performed while being axially supported by the filter holding member, or may be performed after being once removed from the filter holding member. However, the air filter in the inverted position, that is, the second position is supported by the filter holding member in that posture. For example, the lower end of the air filter may be supported by the filter holding member and the upper end may be leaned against the front panel of the casing. Further, in the above structure, the air filter can be easily housed in the casing by performing the operation in the reverse order of the operation for taking out the air filter.

[Effect of device]

As is clear from the above description, the present invention has the following excellent effects. That is, when performing the cleaning work of the air filter, it becomes possible to easily and promptly attach / remove the air filter to / from the casing. Further, since the filter holding member holds the filter that is taken out of the casing and is ready for cleaning, the operator can clean the filter without holding the filter. Therefore, particularly in the case of a unit having a large filter, the efficiency is significantly improved by simplifying the work.

【Example】

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3. FIG. 1 is a vertical sectional view showing an air filter housing portion of a floor-standing fan coil unit, and FIG. 2 is a sectional view taken along line II-II thereof. In this fan coil unit, an air filter 3, a blower 2, and a cold / hot water coil (not shown), which are sequentially arranged from the bottom to the top, are housed in a casing 1 having a blower opening (not shown) at the top thereof. It is a thing. The casing 1 has a front surface, a rear surface, an upper surface, and both side surfaces each made of a panel material, and a combination of these in a box shape is located below each side panel and faces a pair of bases. It is placed on 1c and configured. As shown in FIG. 2, the air filter 3 has a filter medium 3a
A frame member 3b framed by the channel member 3g and the frame member 3b
Expanded metal 3c and frame attached to the upper surface of
It is held by a small-diameter wire rod 3d attached to the lower surface of 3b, and has a substantially plate-like shape as a whole. And frame material
As shown by the broken line in FIG. 1, elongated holes 3e are formed in the channel-shaped members 3g forming 3b on both sides which are short sides, as shown by the broken line in FIG. . Further, among the groove-shaped members 3g constituting the frame member 3b, which is the longer one and is located on the front panel side, as shown in FIG. 3, the outside of the groove-shaped member is covered with a filter. A rubber sheet 3f is attached so as to prevent the front panel from being damaged when it is leaned against the front panel. Although not shown, this rubber sheet 3f is not adhered over the entire length of the groove member 3g in the longitudinal direction, and has a width dimension of about the protrusion amount of the flange with respect to the web of the groove member 3g. The object is attached at two positions, which divide the entire length of the channel member 3g into approximately three equal parts. The air filter 3 configured as described above is the above wire rod.
Through the filter holding member 4 formed of metal or synthetic resin so that the surface through which the 3d is passed becomes the filter surface, that is, the surface that most absorbs dust first and fulfills the filter function. Mounted on the lower surface of the casing 1. In this filter holding member 4, the rear end portions of the respective groove-shaped members 4a arranged so that the grooves formed therein face each other have a substantially ladle-shaped cross section and a portion corresponding to the handle of the ladle is formed. It is connected by a stopper member 4b that serves as a stopper when the filter is attached and detached, and its front end is
The upper surface flanges are connected to each other and the lower surface flanges are connected to each other with a round bar 4c to form a frame shape. Channel member
4a is formed such that the width dimension of the groove (dimension between each flange) is slightly larger than the thickness dimension of the filter so that the air filter 3 can be housed therein, and the length of the member itself is equal to that of the filter 3. It is formed to have almost the same length as the depth direction. Further, the channel member 4a is formed with a long hole 4d from substantially the center thereof toward the front.
A through hole 4e having a diameter larger than the width (short diameter) of the elongated hole 4d is formed at the front end portion of the. The air filter 3 is housed inside by the filter holding member 4 configured as described above. In the housed state, the long holes 3e and 4d formed in the filter holding member 4 and the air filter 3 are The filter holding member 4 overlaps only at a substantially central position. A screw 5 is inserted in the portion where the long holes 3e and 4d overlap each other, and a nut 6, a washer 7, and a spacer 8 are used so that the filter holding member 4 and the air filter 3 are in the groove direction of each groove-shaped member, that is, each. The long holes 3e and 4d are slidably engaged along the long diameter direction. It should be noted that the filter material 3a has substantially the same length as the frame material 3b between both sides of the filter material 3a and the frame material 3b so that the filter material 3a does not become entangled with the threaded end portion of the screw 5 when the screw 5 is tightened. The resin plate 9 is stored, and the filter medium 3a and screws 5
Contact with is cut off. Here, the casing 1 to which the air filter 3 is attached will be described. First, in order to support the filter holding member 4 from below, angle steel is fixed to the center of the uppermost portion of the base 1c as the filter support member 1d so that its supporting surface is formed on the upper side. A plate 1e is fixed to the rear panel 1b so as to form a supporting surface on the same surface as the supporting surface. Further, a positioning member 1f, which is bent as a U-shape and formed as a leaf spring, is fixed to the lowermost end of the front panel 1a, and a filter holding member with respect to the above supporting surface is provided immediately above the positioning member 1f. The plate 1g is fixed with a space slightly larger than the thickness of 4. The air filter 3 housed inside the filter holding member 4 is positioned by urging the filter holding member 4 on each support surface and urging the U-shaped positioning member 1f toward the rear panel side 1b. As a result, it is attached to the casing 1. A case where the air filter 3 is taken out of the casing 1 in the air filter mounting structure of the fan coil unit configured as described above will be described. First, the round bar 4c provided on the lower surface of the front end portion of the filter holding member 4 is grasped and pulled down, and then pulled forward obliquely downward. At that time, as shown in FIG. 3, the stopper 4f of the filter holding member 4 comes into contact with the filter support member 1d fixed to the upper portion of the base 1c to position the filter holding member 4 on the pull-out side. Further, at this time, the upper surface of the filter holding member 4 contacts the lower end of the front panel 1a and the case of the blower 2 almost at the same time, and the inclination angle thereof is kept substantially constant. On the other hand, since the air filter 3 is slidably held by the filter holding member 4, up to the position indicated by the imaginary line in the figure,
That is, it is possible to pull out to the position where the filter holding member 4 and the air filter 3 are engaged with each other at the ends of the elongated holes 3e, 4d. When pulled out in this way, the filter surface remains facing the floor, but when its front end is lifted upwards,
The screw 5 can change the direction of the filter surface while moving along the inner peripheral surface of the through hole 4e formed in the front end portion of the filter holding member 4. The attitude of the filter 3 is such that the rubber sheet 3f attached to the front end of the filter 3 is in contact with the front panel 1a of the casing 1, that is, the filter is leaned against the front panel 1a as shown in FIG. The work of taking out No. 3 is completed. If a magnet is provided at a portion of the front panel 1a which the filter 3 contacts, the posture of the filter 3 can be kept leaning against the front panel 1a. On the other hand, the air filter 3 and the filter holding member 4 in this state can be easily mounted at a predetermined position in the casing by operating in the reverse procedure of the above-mentioned take-out operation. As described above, according to the above configuration, the work of taking out, cleaning, and mounting the filter 3 is performed by a semi-automatic operation in a continuous operation, so that it can be performed extremely easily and quickly. In particular, the work can be performed without holding the filter 3 by hand, and the cleaning work can be performed easily with one hand. The present invention is not limited to the above embodiment,
It can be implemented in various other modes. As one mode, it may be configured as follows. First, the length of the angle steel fixed to the casing as the filter support member is extended toward the front panel side of the casing until it substantially contacts the front panel. Then, an opening means such as a sliding door or an opening door is provided at the lower end of the front panel to form an opening through which the filter holding member can pass. When this opening means is used as a sliding door, rails may be provided on both sides of the casing so that the door portion can slide along the front surface of the front panel, and the door may be held in this rail. When the opening means is an open door, one of the upper and lower surfaces of the door may be connected to the front panel by a hinge. When the fan coil unit has such a configuration, the air filter 3 is pulled straight out forward of the casing together with the filter holding member through the opening formed at the lower end of the front panel by the opening means. As described above, according to this modification, when the filter is taken out as in the above-described embodiment, it is necessary to perform a complicated operation such that the front end portion of the filter holding member is once pulled down and then taken out to the front of the casing. The filter can be taken out and attached more easily. Further, for example, the filter holding member of the above-mentioned embodiment may be divided into two members, a first member and a second member, which will be described next. First, the first member is formed as a frame member located around the filter, and the rear end portion of the first member and the rear end portion of the filter are rotated using, for example, screws as in the above-described embodiment. It suffices to rotatably support the shaft. However, the first
The range in which the member is allowed to rotate the filter is from the first position in which the filter surface faces downward to the second position in which the filter surface faces forward or forward and upward, and in this respect, the embodiment described above is used. Is the same as. Next, the second member is configured to allow the first member to slide along the filter surface within the second member, and to be retractable in front of the casing. For example, the second member may be configured to have a relationship with the first member so as to have a relationship similar to the relationship of the filter holding member with respect to the air filter in the above-described embodiment. Specifically, the groove members facing each other may be formed. A member, a stopper member that connects the rear end of the groove-shaped member, and a round bar that connects the upper surface flanges and the lower surface flanges of the front end of the groove-shaped member to each other in a frame shape. It is sufficient to store one member. If the air filter and the filter holding member are configured as described above, the filter moves together with the first member when being pulled out from the casing or attached to the casing, and when the filter is pulled out from the casing, the first filter is moved. Only the filter rotates with respect to the first member while the member is fixed with respect to the second member. According to the above configuration, only a simple operation such as only rotation or only sliding is performed between the air filter and the first member or between the first member and the second member, so that the attachment / detachment operation is easier. It will be done. Further, in the above-described embodiment and its modified example, the reversal of the filter surface was allowed only when the entire filter was positioned in front of the casing, but for example, the reversal axis was set at the center of the filter or slightly more than that. If it is formed on the rear side, it is possible to reverse the filter surface with the rear side of the filter left in the casing. However, as a condition to make the filter reversible, make the size from this reversal axis to the rear end of the filter smaller than the distance between the position of the reversal axis and the floor when it is pulled out to the position where the filter is reversed. In addition, in order to avoid interference between the filter and the filter holding member during its rotation, for example, the lower surface side flanges of the groove-shaped members on both sides of the filter holding member are partially cut out and their cross sections are reversed. It is necessary to make it L-shaped. However, with such a configuration, the filter can be taken out with a smaller movement amount, that is, with a simpler operation. Furthermore, the filter and the filter holding member do not necessarily have to be fixedly connected with a screw or the like. For example, a state in which the filter is once pulled out to the front of the casing together with the filter holding member and then completely separated from the filter holding member, and in this state, the filter is erected with respect to the filter holding member protruding to the front surface of the casing. You may put it on it. In the case of such a configuration, as the filter supporting means, the receiving surface for supporting the filter end portion may be formed on the filter holding member.
