Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier that filters tap water through various filters to obtain purified water.

[0002]

2. Description of the Related Art A water purifier obtains purified water by filtering through various filters. Types of filters include activated carbon, hollow fiber membranes, ceramics, reverse osmosis membranes, etc., and are used singly or in combination. Of which
The present invention relates to a water purifier using a filter made of a reverse osmosis membrane.

[0003] A reverse osmosis membrane filter is used by applying pressure to the osmosis membrane from the opposite side. Since the flow rate becomes extremely small at the water pressure of the tap water, the filter is usually used by applying pressure with a pressure pump. The water purified by the reverse osmosis membrane filter is stored in a water storage tank and supplied by a water pump. Therefore, it is necessary to electrically control the operation of the pump, the water level gauge of the water storage tank, and the like.

For this reason, in a conventional water purifier equipped with a reverse osmosis membrane filter, as shown in FIGS. 4 and 5, an electric component A such as a circuit breaker is incorporated in a panel closing portion in the water purifier main body 1. An electric box B is provided, and a monitoring / operation device D such as a water level indicator light L and an operation switch S / timer T is provided on a front openable / closable panel 2 of the water purifier main body 1, and the monitoring / operation device D is connected to an electric device. The box B is connected to the box B by a lead wire C as shown in FIG.

In FIGS. 4 and 5, reference numerals 3 and 4 denote carbon filters for filtering tap water, 5 denotes a sediment filter, 6 denotes a reverse osmosis membrane filter for purifying filtered water, and 7 denotes a reverse osmosis membrane filter. Reference numeral 6 denotes a pressurizing pump for applying reverse osmotic pressure to the osmosis membrane, and reference numeral 8 denotes a water storage tank for storing water purified by the reverse osmosis membrane filter 6.

[0006]

The conventional water purifier has the following problems. Since the monitoring / operation devices D such as the water level indicator L and the operation switch S / timer T are exposed on the outer surface of the front obstruction panel 2 of the water purifier main body 1 as shown in FIG. Wiring by a lead wire C from the electrical box B to the monitoring / operation device D is necessary, which requires a cost for parts and man-hours. Since the electrical parts are scattered, it takes time and effort to waterproof, and is not perfect. Operation tests cannot be performed until all components such as piping and electrical equipment are completed, and it takes time and effort to disassemble and maintain when there is a problem. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and has as its object to reduce a failure / breakage rate, increase safety, and improve assemblability.

[0007]

In order to solve the above-mentioned problems, a water purifier of the present invention comprises an electric equipment box having monitoring and operating devices such as an indicator light and an operation switch at a panel closing portion in a main body of the water purifier. The monitoring and operation equipment of the electrical box is arranged and can be confirmed and operated from a window hole provided in a front closing panel of the water purifier main body.

[0008]

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be specifically described with reference to FIG. In the figure, reference numeral 1 denotes an electric control type water purifier main body having a front obstruction panel 2 that can be opened and closed.
Conventional carbon filters 3, 4, sediment filter 5, reverse osmosis membrane filter 6, pressure pump 7,
Water storage tank 8, float switch 8a, water pump 9,
Hollow fiber membrane filter 10, water supply port 11a and water purification port 11
b etc.

According to the present invention, a monitoring and operating device D such as a water level indicator light L, a circuit breaker E and a timer T is mounted on an electrical box B, and the electrical box B with the monitoring and operating device D is attached to a water purifier. It is arranged in the panel closed part in the main body 1 and the monitoring and operating equipment D of this electric equipment box B is confirmed and checked through the window hole 12 provided in the front closing panel 2 of the water purifier main body 1.
It is characterized in that it can be operated, and a transparent cover plate 13 that can be opened and closed and fixed by a hinge 14 is provided in the panel window hole 12 as shown in FIG.

[0010]

The water purifier of the present invention has the gist of the structure described in claim 1 and has the following effects. (1) Monitoring on the outer surface of the front obstruction panel 2 of the water purifier body 1
Since the operating device D does not appear, there is no problem of breakage or erroneous operation. (2) Since the monitoring and operation device D is attached to the electrical component box B, there is no need for wiring as in the related art, and the cost for parts and the number of work steps are reduced. (3) Since the electrical components are in the electrical component box B, they are easily waterproofed. (4) Since the electrical box B can be manufactured independently, if only one electrical box B is provided, an operation test can be performed only by connecting a connector, and no labor is required for disassembly work and maintenance.
