  2. In Article 1, A multi-tap having a status display function, characterized in that when the main power switch (140) is turned ON, the above-mentioned processing unit (170) loads the accumulated power consumption and accumulated usage time stored in the storage unit (190), calculates the current power consumption using the voltage and current values measured by the power monitoring unit (160), updates the accumulated power consumption and accumulated usage time and displays them on the display unit (180), and stores the accumulated power consumption and accumulated usage time of the storage unit (190).
  3. In Article 1, A multi-tap having a status display function, characterized in that the above-mentioned calculation processing unit (170) calculates usage status information including current voltage, current power consumption, cumulative power consumption, and cumulative usage time, displays it in real time on the display unit (180), and periodically stores the updated cumulative power consumption and cumulative usage time in the storage unit (190).
  4. In Article 1, The above calculation processing unit (170) displays the current power consumption in a normal lighting state on the display unit (180) if the current power consumption, cumulative power consumption, and cumulative usage time, which are usage status information of the multi-tap (100), do not exceed the set values of recommended power consumption, recommended power consumption, and recommended cumulative power consumption. A multi-tap having a status display function, characterized in that the above-mentioned operation processing unit (170) displays the current power consumption in a blinking state on the display unit (180) when the current power consumption exceeds the recommended power consumption, displays the accumulated power consumption in a blinking state on the display unit (180) when the accumulated power consumption exceeds the recommended accumulated power consumption, and displays the accumulated usage time in a blinking state on the display unit (180) when the accumulated usage time exceeds the recommended accumulated usage time.

Description

Multi-tap with usage status display function The present invention relates to a multi-tap having a usage status indicator function, and more specifically, to a multi-tap that prevents fires and enables safe use by displaying various status information of the multi-tap to prevent the user from excessively connecting electrical and electronic devices to the multi-tap and to check the replacement time of the multi-tap, thereby allowing the user to recognize and respond to the usage status. With the widespread adoption of various types of electrical and electronic devices (hereinafter referred to as "electrical and electronic devices") due to the influence of industrialization and technological advancements, multi-taps of various structures are being used as a means to receive and distribute power from outlets embedded in the walls of offices or residential buildings. Most of these power strips have a structure in which multiple outlets for distributing AC power are equipped in a single casing. Meanwhile, in the past, a multi-tap capable of checking whether the allowable power consumption is exceeded in a general multi-outlet has been proposed. Related prior art includes "a multi-tap equipped with a power consumption display means" in Public Utility Model No. 20-2009-0000333 (Reference 1) and "a multi-tap equipped with a USB including a power consumption checking function" in Registered Patent No. 10-1462871 (Reference 2). However, the power strips proposed in references 1 and 2 only display power usage through the power strip, so users can check power usage information either on the power strip itself or at a remote location. When the power strip is used by connecting plugs of multiple various electrical and electronic devices, users cannot directly check the real-time power consumption (kW) or the cumulative power consumption (kWh) directly on the power strip in real-time. Furthermore, when conventional power strips are used with multiple electrical and electronic devices connected and exceeding the maximum allowable current limit, there is a high risk of fire and explosion due to reduced durability caused by deterioration. Therefore, manufacturers of power strips recommend that users (or consumers) replace these power strips with new ones for safe use after a certain period of time (e.g., 1 to 2 years from the date of manufacture or use) has passed since purchase. However, conventional power strips lack the functionality to provide various information that allows users (or consumers) to check the replacement timing. FIG. 1 is a perspective view of a multi-tap having a status indicator function according to one embodiment of the present invention. FIG. 2 is a diagram showing the connection status of a multi-tap having a status display function according to one embodiment of the present invention. FIG. 3 is a diagram showing the disconnected state of a multi-tap having a status indicator function according to one embodiment of the present invention. FIG. 4 is a control configuration diagram of a multi-tap having a status display function according to one embodiment of the present invention. FIG. 5 is a drawing illustrating an example of a status information display of a multi-tap having a status display function according to an embodiment of the present invention. Hereinafter, a multi-tap having a status indicator function according to the present invention will be described in detail with reference to the attached drawings. Furthermore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all technical concepts of the present invention; therefore, at the time of filing this application, there may be various equivalents and modifications that can replace them. FIGS. 1 to 4 are drawings illustrating a multi-tap having a status indicator function according to an embodiment of the present invention. According to this, the multi-tap (100) of the present invention can be used to supply power to various electrical and electronic devices such as smartphones, laptops, and PCs while standing upright on a floor or table in an office or residential building, and can receive household power and distribute it to multiple plug sockets, and one or more other multi-taps (200) (hereinafter referred to as 'extension taps') can be connected and disconnected. This multi-tap (100) is supplied with household power and connected to another extension tap (200), and one or more other extension taps (200) can be connected (or assembled) in succession to the extension tap (200). Therefore, when a plurality of extension taps (200) are connected in succession to the upper part of the multi-tap (100) to form a tower type, it can perform the function of a tower-type multi-tap that can be placed on the floor or table of an office or residential building and used. Of course, the main function of the multi-tap (
