The first embodiment will be described with reference to the drawings. FIG. 1 shows a floor-standing air conditioner 1 according to Embodiment 1, and a top panel 2 that covers the top surface of the air conditioner 1 and is formed of iron, resin, or the like, and an air conditioner. A substantially rectangular casing is formed by two side panels 3 that cover both side surfaces of 1, a front panel 4 that covers the front surface of the air conditioner 1, and a rear panel (not shown) that covers the back surface of the air conditioner 1. Forming. Here, the air conditioner 1 is described as a device having a width of about 1400 mm, a height of 2000 mm, and a depth of about 800 mm, but the shape is not limited thereto.

  Although not shown in the figure, the main parts include a blower fan for sucking air, a fan motor for driving the fan, a dust filter for removing dust contained in the sucked air, and heat for exchanging the sucked air. The main drain pan that catches the drain water that has been generated and dropped in the heat exchanger, the electrical box that contains the control board that controls the electrical parts such as the fan motor and solenoid valve, and the refrigerant piping are applied. The air conditioner is appropriately arranged based on the specifications of the air conditioner. As an air conditioner to be applied, for example, as in the first embodiment, a type that sucks air from the front surface or side surface and blows out heat-exchanged air from the top surface, or conversely, air from the top surface. There are various types of air conditioners, such as those that inhale and heat-extracted air from the front or side, so that each unit is arranged according to the type of air conditioner.

  The top panel 2 is provided with an air outlet 6, and the front panel 4 is provided with a service panel 5 that is opened when an operator performs work such as maintenance inside the air conditioner 1. Attached to the front panel 4.

  Further, the service panel 5 is provided with an air suction port for sucking air from the front surface of the air conditioner 1, and the sucked air is heat-exchanged by a blower fan and a heat exchanger provided inside the casing, It blows out from the air blower outlet 6 provided in the panel 2. FIG. In the first embodiment, the inside of the casing of the air conditioner 1 itself is configured as an air path.

  In the first embodiment, the service panel 5 is provided with a detachable panel in the form of a single sheet metal, but may be of a door type, and if so, the air conditioner 1 The front surface can be easily opened, and the labor for maintenance work is reduced. In addition, the position where the service panel 5 is attached is not limited to the front panel 4. For example, when the air conditioner 1 faces only the back surface to the wall surface and the side space is not restricted, the service panel 5 is attached to the side panel 3. May be installed.

  Furthermore, the base 7 is attached to the air conditioner 1 integrally with four support pillars 11 as shown in FIG. 4 at the bottom of the bottom surface of the air conditioner 1, and the upper surface of the base 7 is the air conditioner 1. It has the same area as the bottom surface. When the air conditioner 1 is installed on the floor surface 100, a first nut 82 and a second nut 83 are fastened to a fixing bolt 80, which will be described later, using the base 7 in order to prevent a fall due to an earthquake or the like. The air conditioner 1 is fixed to the floor 100 by raising it. In addition, the support column 11 is integrally formed as a frame forming a housing as the entire air conditioner 1.

  The base 7 has a width and depth that are smaller than the outer dimensions of the casing of the air conditioner 1, so that the space for installing the bolts and nuts does not occupy the space for installation work, and the corner portion surrounded by the wall surface In the case of installation in a gap, the gap with the wall surface can be reduced.

  Moreover, in this Embodiment 1, although the housing | casing is comprised with the iron material, it does not prevent comprising with another material. Further, for example, each panel constituting the casing other than the frame or the like that requires strength may be formed of a resin molded product, and by doing so, the air conditioner 1 can be reduced in weight.

  Further, in the first embodiment, the base 7 is formed of a resin molded product, and polypropylene is used as a material in consideration of oil resistance. However, the base 7 is made of a material having a strength capable of supporting the air conditioner 1. It is desirable to be.

  The structure of the base 7 will be described with reference to FIGS. FIG. 2 shows the overall structure of the base 7, and FIG. 3 shows an enlarged view of a portion A in FIG. The base 7 has a substantially box-like shape, and mounting holes 8 for fixing to the floor surface 100 with fixing bolts 80, first nuts 82, and second nuts 83 are provided on the bottom surfaces near the corners of the four corners. The wall member 9 is welded and fixed to the base 7 so as to surround the periphery or part of the periphery of the mounting hole 8.

  When the first nut 82 and the second nut 83 are tightened in the mounting hole 8, the service panel 5 is opened, and the operator enters the air conditioner 1. In order to tighten the nut 83 with the torque wrench 84, the size and height of the wall member 9 are set so that a sufficient space for the torque wrench 84 to enter the periphery of the mounting hole 8 can be secured. The area in which the wall member 9 surrounds the attachment hole 8 may be an area that allows the torque wrench 84 to be rotated with respect to the nut. For example, the area may be about 300 mm square. Moreover, the height of the wall member 9 is good to be the same height as the sub-drain pan 10 mentioned later.

  In the first embodiment, the torque wrench 84 is used to tighten the first nut 82 and the second nut 83, but any tool for tightening the nut may be used. For example, a monkey wrench, It is also possible to use a spanner or the like.

  If it is not installed in the corner portion, it is highly likely that the installation work from the inside of the air conditioner 1 is troublesome, so that the work can be done by looking through the mounting hole 8 from the side surface of the base 7. In addition, the work hole 70 opens in the wall surface of the base 7 in the vicinity of the mounting hole 8. That is, two work holes 70 are provided in the vicinity of the four mounting holes 8.

  Providing each of such work holes 70 facilitates installation at any location and saves time and labor for considering the work space, thereby greatly reducing the labor and time required for the installation by the operator. In the first embodiment, the base 7 is provided at the bottom bottom of the air conditioner 1 as shown in FIG. 1, but the casing of the air conditioner 1 is configured to cover the periphery of the base 7. At this time, the work hole 70 is provided on at least one of the wall surface of the base 7 or the casing of the air conditioner 1.

  Each of the work holes 70 is detachably provided with a closing plate 71 that closes the opening. In the first embodiment, the air conditioner 1 uses the entire inside of the housing as an air path. Therefore, by maintaining airtightness and preventing wind leakage from the work hole 70, it is possible to prevent wind bypass and prevent a decrease in air conditioning capability and dew condensation inside the housing. If the air conditioner 1 is a type of air conditioner that does not use the entire interior of the housing as an air passage as in the first embodiment, the closing plate 71 is not particularly necessary and may or may not be provided.

  The work hole 70 has such a size that a tool for tightening a nut can be moved, for example, a width of about 200 mm and a height of about 100 mm, and can be easily removed with a screw or the like. The hole 70 may not be a square hole as described in the first embodiment, but may be any hole as long as it can work, such as a circular or elliptical hole.

  In the first embodiment, two work holes 70 are provided at each corner of the air conditioner 1 so that the work can be performed from the front, rear, left, and right of the air conditioner 1. For example, the air conditioner 1 When 1 is installed in a gap surrounded by a corner or a wall, the work holes 70 at the two corners on the back side are not necessary. Further, for example, the mounting holes 8 at the two corners on the front side do not need to be provided at the corners, but are provided closer to the front side from the corners of the base 7 and the work hole 70 is provided on the front side. Can be improved.

  In Embodiment 1, the shape is such that the upper part of the mounting hole 8 is opened at the four corners of the base 7 so that the work can be performed from the inside of the air conditioner 1. With respect to the mounting holes 8 provided at the two corners disposed in the space, the work space does not pose a problem, so that the work can be performed from the inside or the outside of the air conditioner 1 or from either one. It may be a simple shape.

  Further, as shown in FIG. 2, a sub drain pan 10 is placed in a space in the center of the base 7 surrounded by the inner wall of the base 7 and the four wall members 9, and the wall member 9 is a sub drain pan. 10 has a structure capable of preventing water from entering. The shape of the sub-drain pan 10 is not limited to this. For example, the sub-drain pan 10 can be configured as a sub-drain pan by forming the base 7 into a thick plate shape and providing a concave portion in the center.

  The sub drain pan 10 has a shape in which the bottom surface is inclined so that the drain water that has fallen flows in one direction. A mouth 12 is provided.

  In the first embodiment, an operator such as a user opens the drain port 12 from the front of the air conditioner 1 and manually drains the drain water stored in the sub-drain pan 10. However, if the drain port 12 is opened on the bottom surface of the base 7 and the pipe is placed under the floor to drain the drain water, the maintenance work of the sub-drain pan 10 is reduced. Further, at this time, an antibacterial agent or the like is preferably kneaded so that the inside of the drainage port 12 or the pipe lined under the floor is not clogged with dust or mold.

  As such a structure, when the drain water overflows from the main drain pan, or when the water falls due to condensation on the heat exchanger or the refrigerant pipe, the sub drain pan 10 is provided on the base 7 to function as an emergency seed pan. Thus, it is possible to prevent water that has been generated and dropped in the housing or the base 7 from flowing around the attachment hole 8 and leaking from the attachment hole 8 to the outside of the air conditioner 1.

  In the first embodiment, the base 7 is provided with a separate sub-drain pan 10 so that the base 7 has a function as an emergency seed ren pan. However, the sub-drain pan 10 is not provided, and the structure of the base 7 does not leak water. The base 7 itself may have a function as a drain pan. By doing so, it is possible to simplify the assembly of the air conditioner 1 and reduce the cost by not providing the sub-drain pan 10.

  Further, when the air conditioner 1 is installed tilted or when the wall member 9 is shaken due to an earthquake or the like, the water accumulated in the sub-drain pan 10 overflows, and water enters the room from the mounting hole 8. It is provided so as not to leak and has a height that does not flow into the mounting hole 8. Therefore, the wall member 9 only needs to have at least a height that does not allow water to overflow, and usually has a height of 20 mm or more.

  FIG. 4 is a diagram showing a simplified diagram when the air conditioner 1 and the base 7 are integrally attached. 4A is a diagram showing the positional relationship of each member when viewed from above the base 7, and FIG. 4B is an enlarged view of the portion B in FIG. 4A. FIG.

  The air conditioner 1 and the base 7 are integrally assembled by a support column 11. The support column 11 has a length from the top panel 2 of the air conditioner 1 to the bottom surface of the base 7, and is an L-shaped one. These iron members are provided at the four corners of the air conditioner 1 and are welded to and attached to the air conditioner 1 and the base 7.

  Further, the relationship between the distance Y from the corner portion to the closing plate 71 and the length X occupied by the support column 11 is designed such that Y> X. This is so that the support column 11 does not get in the way when inserted and operated.

  Next, tightening of the fixing bolt 80, the first nut 82, and the second nut 83 will be described with reference to FIG.

  Before installing the air conditioner 1, fixing bolts 80 are embedded in the floor surface 100 in advance, and the fixing bolts 80 are passed through the mounting holes 8 provided in the base 7. 100.

  Further, since the fixing bolt 80 protrudes from the mounting hole 8, the base 7 is fitted using the first nut 82 and the second nut 83 that are passed through the washer 81 from the top and then screwed to the fixing bolt 80. Further, the torque wrench 84 is used to tighten it from above the mounting hole 8.

  Similarly, the other three mounting holes 8 are fastened by a washer 81, a first nut 82, and a second nut 83, and the base 7 is fixed.

  The sizes of the first nut 82 and the second nut 83 are generally those having an outer diameter of about 100 to 120 mm (M10 to 12).

  It should be noted that the fan motor and the blower fan constituting the inside of the air conditioner 1 are arranged in the center, and further, the refrigerant and water pipes are designed not to be arranged below, so that the operator can see from the front of the air conditioner 1. Hands and bolt tightening tools are arranged so that they can reach the mounting holes 8 provided on the rear surface and work can be performed, and each component is arranged as appropriate. By arranging these units with a space in the information of the base 7, it becomes easy to insert the torque wrench 84 into the inside of the apparatus, and workability is improved.

  In the first embodiment, the mechanism for performing the installation work of the apparatus by simply tightening the first nut 82 and the second nut 83 in the mounting hole 8 has been described. However, a large shake such as an earthquake occurs or the air conditioner Because the vibration of the compressor and blower of the air is transmitted to the floor surface 100 through the bolt and the base, the air conditioner may vibrate and the housing may be shaken and damaged. An anti-vibration material may be provided between the base surface at the bottom of the hole and the floor surface 100.

  Moreover, you may raise the intensity | strength of installation fixation by using another member for a ceiling surface or a wall surface.

  The actual installation work of the air conditioner 1 will be described.

  First, after the air conditioner 1 with the base 7 already attached thereto is underfloor work such as piping and wiring, it is transported to the installation location by a lift device or the like, and is provided on the floor surface in advance and protrudes from the floor surface. The fixing bolt 80 is adjusted and placed so as to be inserted into the mounting holes 8 provided at the four corners of the base 7.

  Next, the service panel 5 is opened, and the worker himself enters the inside of the casing, or the operator's arm is put into the casing with the torque wrench 84, or only the torque wrench 84 is encased. The washer 81, the first nut 82, and the second nut 83 are attached to the fixing bolt 80 as shown in FIG. In this case, as a matter of course, the service panel 5 has good workability if it is of a size that allows the operator himself to enter the inside of the casing, and further facilitates maintenance work after installation.

  However, the service panel 5 may have a size that allows at least a tool for tightening a nut such as the torque wrench 84 to reach the mounting hole 8 provided on the back side due to design restrictions and the like.

  Furthermore, depending on the installation location, work from the outside may be possible, and at that time, the work from the work hole 70 is naturally acceptable.

  With the above configuration, the air conditioner 1 can be installed from inside or outside the air conditioner 1, and wall installation, in particular, the corner portion, and further, the back surface and both side surfaces are surrounded by walls. Even in the installation work in the gap, the restriction condition of the installation work is reduced, and the effect of being easy to install even if the work space is small is obtained.

  In the first embodiment, the floor-standing air conditioner has been described. However, the present invention can also be applied to an air conditioner or a refrigeration apparatus having the same configuration.
