Submergence detecting device
The submergence detecting device includes a submergence detecting terminal and a submergence judging device. The submergence detecting terminal is composed of at least two conductive sections disposed within a case. The submergence detecting terminal detects a submergence state by coming into contact with water that has infiltrated a predetermined area within the case. The submergence judging device is disposed within the case. At least a signal related to submergence detection is inputted into the submergence judging device from the submergence detecting terminal. The submergence judging device then judges whether or not submergence has occurred. The submergence detecting terminal is disposed in a position away from the submergence judging device in the downward direction.
1. A submergence detecting device, comprising:
a submergence detecting terminal which is composed of at least two conductive sections disposed within a case and detects a submergence state at a predetermined area within the case;
a control board on which a submergence judging device disposed within the case is mounted, the submergence judging device being configured to receive at least a signal relating to submergence detection from the submergence detecting terminal and judge whether or not submergence has occurred; and
a resin member that covers and insulates a portion of the submergence detecting terminal, wherein
the submergence detecting terminal is disposed in a position away from the submergence judging device, mounted on the control board, in a downward direction,
the submergence detecting terminal is supported by the resin member,
the resin member is supported by a wall of the case, and
the resin member is disposed in a position spaced apart from the control board.
2. The submergence detecting device according to claim 1 , wherein the submergence detecting terminal has at least three conductive sections, wherein a lowest position of one of the conductive sections is disposed higher up than that of others of the conductive sections.
3. The submergence detecting device according to claim 1 , further comprising a fluid guiding section provided in a bottom portion within the case so as to guide fluid which has infiltrated into the case to an area directly below the submergence detecting terminal.
4. The submergence detecting device according to claim 2 , further comprising a fluid guiding section provided in a bottom portion within the case so as to guide fluid which has infiltrated into the case to an area directly below the submergence detecting terminal.
5. The submergence detecting device according to claim 1 , wherein the submergence detecting terminal is mounted away from the control board.
6. The submergence detecting device according to claim 1 , further comprising a sensor board on which the submergence detecting terminal is mounted, the sensor board being separate from the control board and mounted below the control board in the downward direction.
