JP2012-0799994

  Generally, in a hot water supply apparatus, a filter is provided on the downstream side of a water inlet, and foreign matters are removed from water supplied through the water inlet. However, in general, the connection portion between the water inlet and the hot water outlet has a common shape or an approximate shape, so that they may be misconnected during construction or maintenance, and foreign matter may enter the instrument.

  As a measure for making it difficult to cause such an erroneous connection, for example, a method of marking characters in the vicinity of each of the water inlet and outlet in the case of a hot water supply device, etc. can be mentioned, but the character hidden behind the case is hidden. It is difficult to see visually, and there is a risk of troublesome confirmation or oversight.

  On the other hand, although it does not relate to an erroneous connection between a water pipe and a hot water pipe, a technique such as Patent Document 1 has also been proposed as a technique for preventing an erroneous connection between pipes. However, the technique of Patent Document 1 has a problem that it takes time and labor to perform the confirmation work because the pipe cannot be identified unless the control unit performs a control operation.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an identification tool for a hot water supply device that can clearly show a water inlet and a hot water outlet.

An identification tool for a hot water supply apparatus according to one aspect of the present invention,

A second display member attached to the second exposed conduit or a portion connected to the second exposed conduit, and representing at least one of a symbol or a figure indicating hot water;
Have

  Since the identifier for the hot water supply apparatus can be configured as a member different from the case of the hot water supply apparatus, it is easy to improve the visibility as compared with the structure in which the case is engraved. Therefore, it becomes easier for the related person to quickly recognize that the first exposed pipeline is a pipeline related to water and the second exposed pipeline is a pipeline related to hot water. Therefore, when the person concerned confirms which is the pipe line related to water and which is the pipe line related to hot water, it becomes easy to perform the confirmation work more quickly and accurately.

The identification tool 100 for a hot water supply device shown in FIGS. 3, 4, etc. can be configured as a member different from the case 5 of the hot water supply device 1. Easy to increase. Therefore, it becomes easy to make a person concerned recognize quickly that the 1st exposure pipeline 15 is a pipeline about water, and the 2nd exposure pipeline 17 is a pipeline about hot water. Therefore, when the person concerned confirms which is the pipe line related to water and which is the pipe line related to hot water, it becomes easy to perform the confirmation work more quickly and accurately.

  For example, if the first external pipe 191 and the second external pipe 192 are erroneously connected, the first external pipe is connected to the outlet (the tap outlet 18) of the tap pipe 10, which is a pipe without the water filter 35. If the channel 191 is erroneously connected and water is supplied from the first external pipe 191 in this state, foreign matter mixed in the water enters the hot water supply device via the hot water discharge pipe 10. There is a risk of it. However, if the above-described discriminating tool 100 is used, the person concerned can surely confirm which is a pipe related to water and which is a pipe related to hot water, so that such erroneous connection can be prevented. As a result, intrusion of foreign matter due to erroneous connection can be effectively prevented.

  As shown in FIG. 3, the first display member 110 includes a first plate-like member 112 configured in a plate shape, and a plurality of penetrations formed so as to penetrate the first plate-like member 112 in the thickness direction. The part 112a represents a symbol (specifically, a Chinese character) indicating “water”. The 2nd display member 120 has the 2nd plate-shaped member 122 comprised by plate shape, and "hot water" by the some penetration part 122a formed so that it might penetrate in the thickness direction in the 2nd plate-shaped member 122. (Specifically hiragana) is shown. The identification tool 100 configured in this way can represent a symbol indicating water or hot water in a simpler configuration in each of the first display member 110 and the second display member 120. Moreover, since a symbol can be represented by a plurality of penetrating portions, the symbol represented can be recognized when viewed from either the front side or the back side.

  In the identification tool 100 shown in FIGS. 3 and 4, the surface portion of the first plate-like member 112 is represented by the first color, and the surface portion of the second plate-like member 122 is different from the first color. It is represented by the color. In this way, each of the first display member 110 and the second display member 120 can also be distinguished by color, and those who know which color indicates which display member, which is a tube related to water It is possible to confirm which of the pipes is a pipe related to hot water more quickly and more accurately.
