Description

  The present invention relates to a stationary water purifier that is used in the vicinity of a sink or the like.

  As a water purifier for filtering tap water, a faucet directly connected water purifier that is directly attached to a faucet is widely used. The faucet-directly connected water purifier can be used easily without taking up space with a sink or the like.

  In addition to the removal of trash such as lime and iron rust in tap water, there is a growing interest in removing harmful substances, and the development of water purifier cartridges with an increased number of substances to be removed is also progressing.

  The faucet-directly connected water purifier is compact and easy to use in the sink, but there is a limit to the increase in size of the cartridge, and on average it requires regular replacement for several months.

  From such a point, a medium-to-large water purifier has been proposed and put into practical use that can increase the size of the cartridge to maintain a long life and secure a sufficient amount of water.

  For example, a built-in type in which the cartridge is stored under the sink and directly connected to the faucet, or a stationary water purifier in which only the switching valve is attached to the faucet and the cartridge and the water discharge part are installed around the sink are proposed. It has been put into practical use.

  On the other hand, from the viewpoint of improving convenience, a water purifier having a function of displaying an appropriate combination of a lamp, a buzzer, an LCD, an LED, or the like has been proposed as a function of notifying the replacement timing of the cartridge.

  For example, a faucet-directly connected water purifier is provided with an LCD display unit and a movable part that can stand up the LCD display unit is provided (Patent Document 1), or a flow meter and a display function are unitized. The thing (patent document 2) etc. which were made to attach according to the aspect of this is proposed.

  However, in the case of the faucet direct-coupled water purifier as proposed in Patent Document 1, since it is used by being fixed to the faucet, when a fluorescent lamp or sunlight near the faucet is inserted and the display part such as an LCD becomes difficult to see, Although moving parts that can be installed upright are effective, they were not compatible with stationary water purifiers.

  On the other hand, when it becomes a large water purifier such as a stationary water purifier, the display unit moves the water purifier main body when the display unit is attached to the base of the water discharge pipe as proposed in the water purifier main body or Patent Document 2. For example, the display unit must be viewed.

In addition, in the case of a large water purifier such as the stationary water purifier proposed in Patent Document 2, the installation location around the sink is often limited, and the display unit is difficult to see or completely visible. In many cases, there was no choice but to use it.
