Description

  The present invention relates to a hot water supply apparatus having a heat insulating material that reduces the amount of heat released from a hot water storage can body.

Conventionally, this type of hot water supply device has been designed to keep warm the hot water stored in the hot water storage can body by surrounding the outer shell of the hot water storage can body with a plurality of molded heat insulating materials. And according to this structure, compared with the case where glass wool is wound as a heat insulating material around a hot water storage can body, the man-hour at the time of manufacture assembly is reduced significantly, and workability | operativity improved. (For example, refer to Patent Document 1).
Japanese Patent Laid-Open No. 08-247554

  By the way, considering the small housing situation in Japan, it will be required to reduce the size of the entire hot water supply device, but the capacity of the hot water storage can itself will be reduced accordingly. If the capacity of the hot water storage can is reduced, the hot water problem that the hot water to be discharged in the hot water storage can be exhausted easily occurs, so the effect of the temperature drop due to the heat dissipation of the stored hot water becomes serious. Keeping warm water in the body is an important issue.

  In order to meet the above requirements, the present invention is characterized in that, in the hot water supply apparatus, a hollow space layer is provided above the hot water storage can body of the foam heat insulating material. According to the space layer, only the foam heat insulating material is provided. Not only the heat insulation effect by the space layer but also the amount of heat released from the upper part of the hot water storage can body can be suppressed.

  According to the present invention, since the hollow space layer is provided above the hot water storage can body of the foam heat insulating material, the amount of heat released from the upper portion of the hot water storage can body can be particularly suppressed.

  1st invention is a hot water storage apparatus, the hot water storage can body to which the several piping was connected, the heating apparatus which heats water, the foam heat insulating material which covered the hot water storage can body from the circumference | surroundings, a hot water storage can body, and foaming An exterior body for housing the heat insulating material is provided, and a hollow space layer is provided above the hot water storage can body of the foam heat insulating material.

  According to this, the heat radiation amount from the upper part of the hot water storage can body can be particularly suppressed by the heat insulating effect by the space layer as well as the foam heat insulating material.

  According to a second invention, in particular, in the first invention, the foam heat insulating material is composed of at least a front surface side heat insulating material, a rear surface side heat insulating material, and a top surface heat insulating material, and the hollow space layer includes a front surface side heat insulating material and a rear surface heat insulating material. It is formed by combining a side heat insulating material and a top surface heat insulating material.

  According to this, since a hollow air layer is formed by combining the components without forming the foam heat insulating material in a hollow shape, the molding process of the foam heat insulating material is facilitated.

  According to a third aspect of the invention, in particular, in the second aspect of the invention, the top heat insulating material has a concave space forming portion for forming a hollow space layer and a pipe shape connected from above the hot water storage can body. And a pipe heat insulating part having a shape.

  A plurality of pipes are connected to the hot water storage can body, and if a through hole for piping is simply provided in the space forming portion above the hot water storage can body, heat is radiated from the through hole, and no matter how much the space forming portion is provided. Heat dissipation occurs from the space layer, and a sufficient heat insulating effect cannot be obtained. Then, by providing an independent space formation part and piping heat insulation part in a top | upper surface heat insulating material, the thermal radiation from the space layer by piping can be suppressed and the heat insulation effect can be heightened.

  In a fourth aspect of the invention, in particular, in the third aspect of the invention, vertical columns having the same height are provided at the uppermost portions of the front side heat insulating material and the rear side heat insulating material.

  By installing a vertical column with the same height at the top of the front and rear insulations, the product rigidity in the vertical direction is improved, and even if people are placed on the top surface due to electrical work during product installation, etc. Therefore, it can be safely operated and can be stacked vertically when products are stored, so that a larger number can be stored with less space.

  In a fifth aspect of the invention, in particular, in the fourth aspect of the invention, a raised ridge is provided in a semi-annular form on the back side of the front side heat insulating material and the rear side heat insulating material, and the ridge and rear side formed on the front side heat insulating material. The height positions of the raised portions formed on the heat insulating material are different.

  Providing a raised ridge between the foam heat insulating material and the hot water storage can body not only enhances the heat insulation effect by forming a space layer, but also allows the hot water storage can to be stably installed by the ridge.

  An embodiment of the present invention will be described below with reference to the drawings. In addition, this invention is not limited by a present Example.

(Embodiment)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a front surface of a hot water supply apparatus with the front plate removed. Inside an exterior body 200 constituting the hot water supply apparatus 100, a foam heat insulating material 300 covering a hot water storage can body (not shown), There are a water supply pipe 201 for supplying water into the hot water storage can and a hot water discharge pipe 202 for discharging hot water stored in the hot water storage can. A heat exchanger 203 is provided in front of the exterior body 200, and is used for heat exchange between hot water circulating as bathtub water or hot water for floor heating and water in the hot water storage can body. In addition, although the structure which uses a heat pump cycle as a heat source is shown in FIG. 1, the hot water supply apparatus of the form which heats the low temperature water in a hot water storage can with an electric heater may be sufficient.

  Next, details of the foam insulation 300 will be described with reference to FIGS. The foam heat insulating material 300 is formed by combining the foam heat insulating material (front) 310 and the foam heat insulating material (rear) 320, and further covers the ceiling side with the foam heat insulating material (top side) 330. Further, the bottom of the hot water storage can body is covered with a foam heat insulating material (bottom side) 340.

  Furthermore, as shown to Fig.3 (a), the protruding part 350 is formed in the semi-annular form along the horizontal direction inside the foaming heat insulating material (front) 310 which faces a hot water storage can body. In FIG. 3, the raised portion 350 is formed of the same material as the foam heat insulating material (front) 310, but a material different from the foam heat insulating material (front) 310 may be added. Similarly, as shown in FIG. 3B, a semicircular raised portion 360 is also formed along the horizontal direction inside the foam heat insulating material (rear) 320 facing the hot water storage can body.

Here, the raised portion 350 and the raised portion 360 are formed at different heights so that the raised portion 350 and the raised portion 360 do not form an annular shape, but this allows hot water storage to store hot water. Even if the foam heat insulating material (front) 310 and the foam heat insulating material (rear) 320 surrounding the can body are slightly thermally expanded and deformed, the hot water storage can body can be stably supported. Further, since a slight space layer is formed between the hot water storage can and the foam heat insulating material (front) 310 or the foam heat insulating material (rear) 320, the heat retaining effect is also improved.

  Further, as shown in FIG. 3, the top surface of the exterior body 200 is held by forming a vertical column 311 and a vertical column 321 at the upper ends of the foam heat insulating material (front) 310 and the foam heat insulating material (rear). Therefore, the rigidity in the vertical direction is improved. Furthermore, since it is formed higher than the height of the foam heat insulating material (top side) 330, even if a load is applied from the top surface of the exterior body 200, the load is not directly applied to the foam heat insulating material (top side) 330.

  This makes it difficult for humans to deform even when they are placed on the top surface during construction work of the product, and allows the product to be stacked on the product when it is stored in the warehouse. The number can be stored.

  Also, as shown in FIG. 4, the back surface side of the foam heat insulating material (top side) 330 is formed along the shape of a space forming portion 331 formed by a recess, a hot water discharge pipe 202 above the hot water storage can body, and the like. There is a pipe heat insulating unit 332. In a hot water supply device that stores hot water in a layered form according to the hot water temperature, there are many occasions where high-temperature hot water is stored in the upper part of the hot water can body, but the upper side of the hot water can body rather than simply contacting the heat insulating material. The heat insulation effect is further increased by forming a space layer on the surface. Therefore, since the space layer is formed between the foam heat insulating material (front) 310, the foam heat insulating material (rear) 320, and the space forming portion 331 of the foam heat insulating material (top side) 330, the heat insulating effect is improved. .

  In addition, piping is installed on the front side of the exterior body 200 in consideration of work efficiency such as maintenance, but the piping of the hot water discharge pipe 202 and the like connected to the upper part of the hot water storage can body is complicated in shape. It was difficult to suppress the amount of heat released by covering. Then, since the pipe heat insulation part 332 is comprised by the shape along piping shape, such as the tap hot water pipe 202, the thermal radiation amount from piping is suppressed.

  As described above, according to the present embodiment, since the raised portions 350 and 360 are formed inside the foam heat insulating material (front) 310 and the foam heat insulating material (rear) 320, the foam heat insulating material (front) 310 is formed. And sufficient heat retention is obtained with respect to the thinness of the foam heat insulating material (rear) 320, and even if the entire hot water supply apparatus is downsized, the amount of heat radiation is alleviated and the occurrence of running out of hot water can be suppressed. Furthermore, since the raised portion 350 and the raised portion 360 are formed at different heights so that the raised portion 350 and the raised portion 360 do not form an annular shape, the hot water storage can body is stably supported. be able to.

  Further, by forming the vertical column 311 and the vertical column 321 at the upper ends of the foam heat insulating material (front) 310 and the foam heat insulating material (rear), the top surface of the exterior body 200 is held, so that the rigidity in the vertical direction is increased. improves. Furthermore, since it is formed higher than the height of the foam heat insulating material (top side) 330, even if a load is applied from the top surface of the exterior body 200, the load is not directly applied to the foam heat insulating material (top side) 330.

  This makes it difficult for humans to deform even when they are placed on the top surface during construction work of the product, and allows the product to be stacked on the product when it is stored in the warehouse. .

  In addition, since a space layer is formed above the hot water storage can body between the foam insulation material (front) 310, the foam insulation material (rear) 320, and the space formation portion 331 of the foam insulation material (top side) 330, The heat insulation effect is improved.

  As described above, the hot water supply apparatus according to the present invention can achieve both the thinness of the heat insulating material and the heat retaining property, and achieves downsizing of the entire hot water supply apparatus, and is not limited to a heat pump water heater. It can be applied to hot water storage type water heaters such as.
