Description

  The present invention relates to a hot water storage type hot water supply apparatus configured by connecting a heat source unit to a tank unit.

  Conventionally, hot water generated using heating means such as a heat pump is stored in a hot water storage tank, and hot water is stored using an auxiliary heat source such as a gas water heater when the hot water storage tank runs out. A type hot water supply apparatus is known (see Patent Document 1 below).

  This hot water storage type hot water supply apparatus includes a tank unit and a heat source unit. The tank unit includes a hot water storage tank and a plurality of pipes extending from the hot water storage tank, and the hot water storage tank and the pipes are accommodated in a tank housing. The heat source unit includes a heat source device, which is a so-called gas water heater, and a plurality of pipes that extend below the heat source device. The heat source unit is placed on and connected to the support base, and the heat source is provided inside the support base. A plurality of pipes extending downward from the machine are accommodated. The heat source unit is assembled adjacent to the tank unit to form an integral composite unit.

JP 2011-158128 A

  However, in the thing of patent document 1, not only the shape of a hot water storage tank and a heat source machine is different, but the positions of piping and other equipment are also different between the tank unit and the heat source unit. For this reason, simply connecting the tank unit and the heat source unit not only unnecessarily exposes the boundary line along the connecting portion, but also the tank unit and the heat source unit have no appearance, and the appearance quality is low. There is an inconvenience.

  Furthermore, when a gas water heater is used as a heat source device, for example, as shown in FIG. 5, a case 14 is provided in which a vessel body 15 containing a heat source portion is closed with a lid 16. However, a flange 17 for abutting the outer peripheral end of the lid 16 is provided on the container 15 so as to project outward. For this reason, even when the heat source unit is connected to the tank unit, the flange 17 of the case 14 of the heat source unit 11 becomes conspicuous, and there is a disadvantage that the appearance is remarkably deteriorated.

  In view of the above points, an object of the present invention is to provide a hot water storage type hot water supply apparatus with high appearance quality.

  In order to achieve such an object, the present invention includes a main body formed by connecting a heat source unit to a tank unit, and the tank unit stores a hot water storage tank for storing hot water heated by an external heating means, and the hot water storage tank. The heat source unit includes a heat source unit in which a heat source unit is accommodated in a case, and a plurality of pipes that extend below the heat source unit. A box-shaped container having a support surface for supporting the heat source device from below so that the top surface and the top surface of the tank unit are located on the same plane; A body and a lid body whose outer peripheral end abuts against a flange projecting outward from the peripheral edge of the open surface of the container body and closes the open surface of the container body, and the heat source apparatus includes: The opposite side surface is in contact with the tank unit. In the hot water supply apparatus, when the lid side of the heat source device is the front side of the main body, a decorative cover is provided to cover at least one side surface of the left and right sides of the main body. The decorative cover includes a rectangular panel and the panel A front molding provided along the front edge of the panel, and a rear molding provided along the rear edge of the panel. The front molding has a flange corresponding to the flange of the heat source machine. And a flange covering portion that covers the outer peripheral end of the lid, and the panel includes an overhanging portion that protrudes inward along the top surface of the main body, and is provided on the top surface or upper side surface of the main body. And a cover connecting means for detachably connecting the decorative cover through the overhanging portion.

  According to the present invention, since the panel of the decorative cover covers the boundary line formed by the connecting portion between the tank unit and the heat source unit, a clean aesthetic appearance can be obtained and the appearance of the hot water storage type hot water supply device can be improved. . Further, since the front molding of the decorative cover is provided with the flange covering portion, the flange covering portion can cover the flange formed on the case of the heat source machine, and the flange of the heat source machine becomes inconspicuous so that the appearance is improved. Can be improved.

  Here, when attaching the decorative cover, the protruding portion of the panel is lowered from above the main body toward the top surface, and the protruding portion is connected by the cover connecting means. Thereby, the decorative cover is attached so that the overhanging portion is hooked on the top surface or the upper side surface of the main body. At this time, the cover connecting means is provided on the top surface or upper side surface of the main body and is not easily seen, and is covered with the overhanging portion of the panel, so that the decorative cover can be attached without deteriorating the appearance.

  In the present invention, it is preferable that the front molding includes an upper extension that extends along a flange on the top surface side of the heat source machine. According to this, the external appearance of the hot water storage type hot water supply apparatus is improved by covering the flange of the heat source machine from the top surface through the corners. Furthermore, when the projecting portion of the panel is connected to the cover connecting means, the upper extension portion of the front molding can be positioned by engaging the top surface side and the corner portion of the flange of the heat source machine. Thereby, even if the said cover connection means is provided in the top | upper surface or upper side surface of a main body and it is hard to see, the attachment operation | work of a decorative cover can be performed smoothly.

  In the present invention, the decorative cover is composed of an upper cover portion that covers the upper side of the side surface of the main body, and a lower cover portion that covers the lower side of the side surface of the main body, and the flange covering portion is The upper cover part and the lower cover part are provided in a front molding of the upper cover part, and the upper cover part and the lower cover part are mutually connected via a boundary line extending in a horizontal direction along a boundary between the heat source unit and the support base of the heat source unit. It is characterized in that it is connected in a divideable manner.

  The upper cover part and the lower cover part are constituted by the upper cover part and the lower cover part so that they can be separated from each other, so that the upper cover part and the lower cover part can be selectively removed according to the maintenance target part in maintenance work or the like. Can do.

  And since the boundary line of the division | segmentation position of an upper cover part and a lower cover part is a line extended in a horizontal direction, the external appearance of a decorative cover hardly deteriorates.

  Further, the piping of the heat source unit is accommodated in the support base of the heat source unit, and the piping of the tank unit is concentrated in the lower half of the main body corresponding to these pipings. At this time, since the boundary line is formed along the boundary between the heat source unit of the heat source unit and the support base, piping connection work and maintenance work can be performed only by removing the lower cover part. High workability.

  Furthermore, it is preferable that the said upper cover part is provided with the connection part extended below the said boundary line and connected with the said main body detachably on the back surface side of the said lower cover part. According to this, the connection part of an upper cover part is concealed by the lower cover part, and is not exposed, and the external appearance fall by a connection part can be prevented.
