Description

[Technical Field]

[0001] The present invention relates to a mounting structure for housing equipment to be installed in a pipe shaft of an apartment building. [Background technology]

[0002] In apartment buildings, pipe shafts are generally installed as storage spaces for water pipes and gas pipes that run vertically. At the opening of the pipe shaft, a metal frame is installed to support an openable door or panel, and residential equipment such as a gas water heater is typically fixed to the metal frame. Because typical household gas water heaters are small, it is relatively easy to fix them to the metal frame of the pipe shaft.

[0003] In recent years, there has been a demand for high-efficiency water heaters, such as heat pump water heaters and water heaters that utilize the exhaust heat of fuel cells, which are more energy efficient than combustion-type water heaters, to be installed in pipe shafts.High-efficiency water heaters are larger and more complex in configuration than gas water heaters, so they are divided into multiple functional units and installed in pipe shafts.

[0004] The multiple functional units of a high-efficiency water heater have narrow widths (lengths in the left-right direction) so that they can be fixed to the metal frame of the opening, and the depth (lengths in the front-to-back direction) is increased to ensure the size necessary to install the functional components. These functional units are often larger and heavier than gas water heaters, and because of the increased depth, the center of gravity of the functional units is further to the rear than that of gas water heaters. Therefore, to improve earthquake resistance, as in Patent Document 1, for example, the functional units are fixed via mounting frames (mounting brackets) to a frame (metal frame of the opening) to which support members that extend in the depth direction and support the functional units are fixed.

[0005] [Patent Document 1] Japanese Patent Publication No. 2023-079874 Summary of the Invention [Problem to be solved by the invention]

[0006] In Patent Document 1, when fixing a functional unit to an opening metal frame, the lifted functional unit is inserted into a mounting bracket attached to the opening metal frame, facing inward toward the pipe shaft, and placed on a support member, and the functional unit is then fixed to the mounting bracket with screws. Because the functional unit is supported by the support member, the screw fixing work is easy.

[0007] However, because the bottom of the functional unit has multiple pipe connectors protruding downward, these connectors must be inserted so as not to interfere with the mounting hardware. Since the heavy functional unit is usually lifted from the outside of the pipe shaft, it is not easy to insert the lifted functional unit into the fixing position. Therefore, the labor required to install the home appliance is significant, and improvements were needed.

[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a mounting structure for housing equipment that allows housing equipment to be easily installed in a pipe shaft. [Means for solving the problem]

[0009] The mounting structure for residential equipment of the invention of claim 1 is a mounting structure for residential equipment that fixes residential equipment to an opening metal frame installed in a pipe shaft of an apartment building via mounting brackets, wherein the mounting brackets have a pair of left and right pillar members fixed to the opening metal frame, an upper beam member connecting the upper ends of these pillar members, a pair of left and right support members that extend from the lower ends of the pillar members inward into the pipe shaft to support the bottom of the residential equipment, and a reinforcing member connecting the ends of these support members, wherein the support members are configured to support the residential equipment placed between the pillar members fixed to the opening metal frame while allowing the residential equipment to slide, and the residential equipment that has slid inward into the pipe shaft is configured to be fixed to the upper beam member.

[0010] With the above configuration, a portion of the lifted household appliance can be inserted into the pipe shaft between the pillars, its bottom placed on the support member, and the appliance can be slid into the pipe shaft while supported by the support member. Therefore, the household appliance can be easily moved from the outside of the pipe shaft to its fixed position, reducing the workload.

[0011] The mounting structure for home appliances of the invention of claim 2 is characterized in that, in the invention of claim 1, a lower beam member is fixed to the front lower part of the home appliance, and both left and right end portions of the lower beam member are fixed to the pillar member. With the above-described configuration, the lower front portion of the appliance is secured to the mounting bracket by the lower beam member, providing a strong connection to the appliance. Furthermore, because the lower beam member slides along with the appliance, the appliance can be slid without the lower beam member colliding with the connecting brackets provided at the bottom of the appliance for connecting external piping.

[0012] The mounting structure for home appliances of the invention of claim 3 is characterized in that, in the invention of claim 1 or 2, the support member has a sliding member on the upper surface that abuts the bottom of the home appliance to reduce friction. According to the above-described configuration, the sliding member allows the household appliance placed on the support member to be easily slid with little force, thereby reducing the workload. [Effects of the Invention]

[0013] According to the mounting structure for housing equipment of the present invention, housing equipment can be easily installed in the pipe shaft. [Brief explanation of the drawings]

[0015] Hereinafter, the mode for carrying out the present invention will be described based on examples. [Example]

[0016] In an apartment building, as shown in Figure 1, a pipe shaft PS is installed in each unit as a storage space for water pipes, gas pipes, etc. The pipe shaft PS is installed, for example, facing a common corridor, and household appliances are installed inside the pipe shaft PS. Note that the arrows F, L, and U in the figure indicate the front, left, and top of the pipe shaft PS, respectively, and also indicate the front, left, and top of the household appliances installed inside the pipe shaft PS.

[0017] A high-efficiency hot water supply system composed of multiple functional units is installed as a residential equipment in the pipe shaft PS. For example, a hot water supply system 1 with a heat source (power generation unit 2) that uses heat generated when a fuel cell generates electricity, a hot water storage tank 3, and a backup combustion-type heat source (combustion unit 4) is installed as functional units. This hot water supply system 1 stores high-temperature water heated by the power generation unit 2 in the hot water storage tank 3, and supplies hot water by adjusting the temperature by mixing the high-temperature water drawn from the hot water storage tank 3 with clean water. If the heat capacity of the hot water in the hot water storage tank 3 is insufficient, the combustion unit 4 heats the water and supplies hot water.

[0018] An opening metal frame 9 having a frame body 6, horizontal bars 7, and vertical bars 8 is fixed to the opening of the pipe shaft PS in order to support doors 5a and 5b for opening and closing this opening. Exhaust gas from the power generation unit 2 during power generation and exhaust gas from the combustion unit 4 during combustion are discharged toward the front of the pipe shaft PS. To prevent this exhaust gas from hitting people, the power generation unit 2 and the combustion unit 4 are fixed to the opening metal frame 9 and installed at the top of the pipe shaft PS. The door in front of the power generation unit 2 is not shown in the illustration.

[0019] The power generation unit 2 and combustion unit 4 have a small width (length in the left-right direction) so that they can fit into the upper part of the pipe shaft PS, and a depth (length in the front-to-back direction) greater than the width, ensuring the size necessary to mount functional components. In order to support the power generation unit 2 and combustion unit 4, which are heavy objects and have a large depth that has shifted the center of gravity to the rear, the opening metal frame 9 is divided into two sections at the top by horizontal beams 7 and vertical beams 8. The front parts of the power generation unit 2 and combustion unit 4 are fixed to the opening metal frame 9 via mounting brackets 20.

[0020] The hot water tank 3 is installed behind the power generation unit 2 and the combustion unit 4. Gas piping and multiple hot and cold water piping are connected to the bottom of the power generation unit 2 and the combustion unit 4.

[0021] 1 and 2, the power generation unit 2 has a box-shaped case 10 whose depth is greater than its width, an exhaust pipe 11 that protrudes forward, and a plurality of connectors 12a-12d that protrude downward from a bottom 10a of the case 10 for connecting external piping such as gas piping and hot and cold water piping. Functional components such as a fuel cell stack and an exhaust heat recovery device are housed inside the case 10.

[0022] Case 10 has a flange portion 10b formed by protruding outward from the front portion of case 10 so as to surround the entire front portion of case 10 in order to be fixed to opening metal frame 9 via mounting bracket 20. A lower beam member 14 for closing the gap between cross beam 7 and case 10 is fixed to flange portion 10b on the front side of bottom portion 10a of case 10 with, for example, screws. Lower beam member 14 is formed by bending a plate-shaped metal material, and the lower end of lower beam member 14 is located lower than the lower ends of connecting brackets 12a to 12d.

[0023] 3, the mounting bracket 20 has a pair of left and right pillar members 21 fixed to the opening metal frame 9, an upper beam member 22 connecting the upper ends of these pillar members 21, a pair of left and right support members 23 extending horizontally rearward from the lower ends of the left and right pillar members 21, and a reinforcing member 24 connecting the ends (rear ends) of these support members 23. The reinforcing member 24 maintains the distance between the rear ends of the left and right support members 23.

[0024] The mounting bracket 20 is fixed to the opening metal frame 9 by, for example, screws at the upper beam member 22, the front end portion of the left-side pillar member 21 bent to the left, the front end portion of the right-side pillar member 21 bent to the right, and the lower end portions of the left and right pillar members 21 bent inward. Then, the flange portion 10b of the power generation unit 2 is fixed to the upper beam member 22 by, for example, screws.

[0025] The pair of left and right support members 23 supports the bottom 10a of the case 10 of the power generation unit 2, which is inserted between the left and right pillar members 21 and placed thereon. The left and right support members 23 each have a horizontal upper surface 23a formed by bending the upper end portion into a stepped shape that is positioned higher toward the inside (the side closer to the other support member 23). The upper surfaces 23a of the left and right support members 23 abut against the bottom 10a to support the power generation unit 2. The support members 23 are formed with a vertical width sufficient to ensure the strength to support a heavy load, and are further strengthened by being bent into a stepped shape and by the rear end being connected by a reinforcing member 24, making them less susceptible to deformation. The vertical width of the support members 23 is greater than the protruding length of the connecting fittings 12a-12d disposed on the bottom 10a of the power generation unit 2.

[0026] The top surface 23a is formed with a narrow width over substantially the entire length of the support member 23 so as to function as a sliding member that reduces friction with the bottom portion 10a. The top surface 23a may be equipped with a sliding member made of, for example, a lubricating synthetic resin to further reduce friction.

[0027] In order to prevent the power generation unit 2 placed on the left and right support members 23 from shifting in the left-right direction, the left and right support members 23 may each be equipped with a guide member 25 as shown in Fig. 4, for example. The upper ends of the guide members 25 extend above the upper surface 23a of the support members 23 and come into contact with the lower end portions of the left and right side surfaces of the case 10 to prevent the power generation unit 2 from shifting left and right.

[0028] Next, the installation of the power generating unit 2 in the pipe shaft PS will be described. The mounting bracket 20 shown in Fig. 3 is inserted into the opening metal frame 9 from the front of the pipe shaft PS and fixed thereto. The power generation unit 2 shown in Fig. 2 is lifted outside the pipe shaft PS, and the rear of the power generation unit 2 is inserted between the left and right pillar members 21 toward the inside of the pipe shaft PS as shown in Figs. 5 and 6. A portion of the rear side of the bottom 10a of the case 10 is then supported by the upper surface 23a of the support member 23. At this time, for example, the connecting bracket 12d on the rear side of the bottom 10a fits between the left and right support members 23, but because there are no members between the left and right support members 23 that interfere with the connecting bracket 12d, the power generation unit 2 can be easily inserted.

[0029] Then, with a portion of the rear side of the bottom 10a supported by the upper surface 23a of the support member 23, the power generation unit 2 is slid inward (rearward) of the pipe shaft PS and inserted to the fixed position (see FIG. 1). At the fixed position, the lower beam member 14 attached to the flange portion 10b abuts against the front and upper surface of the cross beam 7, and both left and right ends of this lower beam member 14 abut against the lower ends of the left and right column members 21. There are no members between the left and right support members 23 that will interfere with the connecting fittings 12a to 12d, and the upper surface 23a of the support member 23 is formed to reduce friction, so the power generation unit 2 can be easily inserted to the fixed position.

[0030] The power generation unit 2 placed in the fixed position is fixed to the upper beam member 22 with screws. In addition, the lower beam member 14 is fixed to the left and right column members 21 with screws. Furthermore, the lower beam member 14 may be fixed to the cross beam 7 with screws, or the lower beam member 14 and the mounting bracket 20 may be fastened together to the opening metal frame 9 for fixation. Although explanation will be omitted, the combustion unit 4 can also be fixed to the opening metal frame 9 of the pipe shaft PS in the same manner as the power generation unit 2. Note that the combustion unit 4 may be fixed via conventional mounting brackets if no support members are required.

[0031] The operation and effect of the mounting structure for the housing equipment, in which the housing equipment is mounted on the opening metal frame 9 of the pipe shaft PS via the mounting bracket 20, will be described. The mounting bracket 20 comprises a pair of left and right column members 21 fixed to the opening metal frame 9, an upper beam member 22 connecting the upper ends of these column members 21, a pair of left and right support members 23 supporting the bottom 10a of the power generation unit 2, which is a residential equipment, and a reinforcing member 24 connecting the rear ends of the support members 23. The left and right support members 23 are configured to support the power generation unit 2 placed between the left and right column members 21 fixed to the opening metal frame 9, while allowing the power generation unit 2 to slide. The power generation unit 2 that has slid inward of the pipe shaft PS is fixed to the upper beam member 22.

[0032] The rear of the lifted power generation unit 2 is inserted between the pillar members 21 into the inside of the pipe shaft PS, and its bottom 10a is placed on the support members 23. The power generation unit 2 can then be slid into the inside of the pipe shaft PS while supported by the support members 23. This allows the power generation unit 2 to be easily moved from the outside of the pipe shaft PS to its fixed position, reducing the workload. Furthermore, because the power generation unit 2 is supported by the support members 23, it is easy to fix the power generation unit 2. This allows for easy installation of household appliances in the pipe shaft.

[0033] Furthermore, the lower beam member 14 is fixed to the lower front portion of the power generation unit 2, and both left and right end portions of the lower beam member 14 are fixed to the pillar members 21, thereby firmly securing the power generation unit 2. The lower beam member 14 slides together with the power generation unit 2, so the power generation unit 2 can be slid without collision between the lower beam member 14 and the connecting fittings 12a-12d disposed on the bottom 10a of the power generation unit 2 for connecting external piping.

[0034] The support member 23 has a sliding member for reducing friction on the upper surface 23a that abuts against the bottom 10a of the power generation unit 2. The sliding member allows the power generation unit 2 placed on the support member 23 to slide easily with little force, thereby reducing the workload.

[0035] In a hot water storage type water heater in which a heat pump type heat source unit and a backup combustion type heat source unit are each functional units, they can be configured to be fixed to the opening metal frame 9 of the pipe shaft PS in the same manner as above. In addition, a person skilled in the art can implement the above embodiment in various modified forms without departing from the spirit of the present invention, and the present invention includes such modified forms.
