Description

A Bidet System and A Control Method for the Bidet System The present invention relates to a bidet system and a method for controlling the bidet system. A bidet is a device installed in a toilet bowl that can automatically perform anal cleansing and female genital cleansing by spraying cleansing water through a nozzle equipped on the bidet. Recently, a system has been developed and is in use in which, when a user terminal and a bidet establish a wireless communication connection, bidet usage information stored in the bidet's memory is transmitted to the user terminal, allowing the user to view a usage report containing this information through an application installed on the terminal. The usage report includes details on how the bidet was operated using specific control information, enabling the user to intuitively check their bidet usage patterns. To generate a bidet usage report, not only the bidet control information but also the time at which the control occurred is required. However, in situations where power is not supplied to the bidet due to a power outage, cleaning, or malfunction, the time information is not updated in real time; instead, it is updated only when power is restored, which presents a problem where the time information transmitted to the user terminal differs from the real-time time information. A review of conventional patent literature reveals the following. Korean Registered Patent Document No. 10-2626641 discloses a technology in which a bidet can be operated by a remote control and/or a user terminal, and state values including the temperature of the washing water or warm air and the intensity of the washing water or warm air are stored in a storage unit equipped in the bidet, and bidet usage information including the stored state values can be transmitted to the user terminal. Although a user using the user terminal can determine bowel habits or usage frequency based on the bidet usage information from the bidet, the aforementioned document does not allow verification of exactly when the bidet was used because the bidet usage information is matched with time information. Furthermore, there is no instruction or suggestion regarding time correction in situations where accurate time information cannot be obtained from the bidet due to circumstances such as a power outage. Korean Published Patent Document No. 10-2014-0134029 discloses a technology in which, when a user terminal is connected to a bidet control device via short-range communication, bidet information is received from the bidet control device and the received bidet information is displayed on the user terminal, thereby wirelessly controlling the operation of the bidet on the displayed screen. Given that the purpose of the wireless communication connection between the bidet and the user terminal is to control the operation of the bidet, no teaching or indication related to time information regarding the time of bidet use can be found. FIG. 1 is a schematic diagram illustrating a bidet system according to an embodiment of the present invention. FIG. 2 is a block diagram illustrating a bidet system according to an embodiment of the present invention. FIG. 3 is a flowchart for explaining signals and information transmitted between components forming a bidet system according to an embodiment of the present invention. Figure 4 is a flowchart explaining the process of correcting time information when the remote control is operating normally but the bidet is not operating normally. Figure 5 is a flowchart explaining the process of correcting time information when the bidet is operating normally but the remote control is not operating normally. FIG. 6 is a diagram illustrating sterilization, hot water tank preheating, and drying operations that can be performed in a bidet according to time information or correction time information. In some cases, to avoid obscuring the concept of the present invention, known structures and devices may be omitted or illustrated in the form of a block diagram focusing on the core functions of each structure and device. Throughout the specification, when a part is described as "comprising" or "including" a component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Furthermore, terms such as "...part," "...unit," and "module" as used in the specification refer to a unit that processes at least one function or operation, and this may be implemented in hardware, software, or a combination of hardware and software.
