In general, a hot water heating system is supplied to a boiler that heats water to generate hot water, a heating pipe installed on the floor of a heating place such as a room or a living room so that hot water heated to a predetermined temperature is circulated by the boiler, and a heating pipe is supplied. It is provided with a hot water distributor for selectively controlling the flow of hot water to be heated to the desired heating place.

1 is a view for explaining a conventional hot water distributor, the hot water distributor as shown there is a hot water supply pipe (2) and hot water recovery pipe (3) horizontally between the fixed side plate (1) disposed on both sides It is installed along the direction.

The hot water supply pipe 2 is formed by a plurality of branch pipes which are connected to the supply pipe body of the hot water supply side heating pipe 4 is integrally protruded, formed in a pipe shape, to control the hot water flow of the heating pipe 4 to the branch pipe. Control valve is installed. In the hot water collecting pipe 3, a plurality of branch pipes to which the hot water collecting side heating pipe 4 is connected are integrally protruded and formed in a hot water supply pipe body formed in the form of a pipe.

In addition, the hot water supply pipe (2) and hot water recovery pipe (3) is provided with an air vent to remove the air injected or formed in the heating pipe (4).

The conventional hot water dispenser distributes the hot water supplied from the boiler (not shown) and supplies it to the heating pipe, and recovers the cooled water through the heating process, so that an effective heating operation is performed. When used for a long time, scale (hereinafter referred to as 'foreign material') is formed in hot water distributor or heating pipe by inorganic or foreign substances included in hot water, so circulation of hot water becomes difficult, heating efficiency decreases, energy consumption increases, heating cost Not only is it increased, but it is also acting as an increase factor of air pollution due to excessive consumption of energy. In addition, the impurities contained in the hot water shorten the life of the boiler and cause a failure, thereby increasing the maintenance cost.

In order to solve this problem, Korean Utility Model Publication No. 20-0058554 discloses a hot water dispenser for heating installed with a strainer 7 inserted therein to filter foreign matter into the opening of the hot water supply pipe 2.

In addition, the Republic of Korea Registered Utility Model Publication No. 20-0200099 discloses a distributor for hot water boiler in which a tubular filter mesh 3 made of stainless steel is installed in the vacancy 1 "of the distributor body 1.

In addition, the Republic of Korea Utility Model Registration No. 20-0263677 discloses a hot water distribution system in which a strainer 4 is installed in the first distribution header 3 of the hot water distributor body (1).

The above-mentioned registered utility model registration Nos. 20-0058554 and 20-0200099 have a strainer (filtration net) inserted and installed inside the hot water supply pipe to filter foreign substances therein, and the registered utility model 20-0200099. Although the arc has the effect of filtering strainers in the distribution header to filter foreign matter therein, it causes various serious problems as described in detail below, so that the arc cannot be practically applied. Hot water distributors of the type shown are generally used.

First, the registered utility model registration Nos. 20-0058554 and 20-0200099 have a structure in which a strainer is built into the inside of a hot water supply pipe, and a registered utility model No. 20-0200099 has a strainer on a distribution header in which hot water flows. As the structure is installed, a large resistance is generated that hinders the smooth flow of hot water, which makes it difficult to circulate the hot water, which lowers the heating efficiency and causes an overload in the circulation pump of the boiler that circulates the hot water, resulting in shortening or failure of the service life. .

Second, Utility Model Registration Nos. 20-0058554, 20-0200099, and 20-0200099 should be made of expensive corrosion-resistant materials to filter foreign matter and install the filter network confidentially or Since various accessories are required for mounting, the manufacturing cost is excessively increased, and the structure is complicated. Therefore, a large amount of time is required for inspection or maintenance.

 Third, since the registered utility model registration Nos. 20-0058554, 20-0200099, and 20-0200099 have a structure in which a filtering network (strainer) for filtering foreign substances is embedded in the hot water supply pipe or the metal strainer body. Since it is impossible to check the degree of accumulation of foreign matters from the outside, there is a disadvantage in that heating is not possible because the flow path is blocked by foreign matters accumulated in the filtering network.

Fourth, the above mentioned Utility Model Registration Nos. 20-0058554, 20-0200099, and 20-0200099 are required to separate the strainer from the hot water supply pipe or distribution head when impurities are accumulated in the strainer and cleaned or replaced. However, at this time, since all the hot water filled in the heating pipe is discharged, it is difficult and time-consuming to work, and also causes a serious pollution of the surrounding environment. In addition, when the strainer is replaced, hot water is unnecessarily wasted, and thus the hot water discharged as described above needs to be refilled.

In particular, the above-described conventional hot water distributor has a serious problem that the heating can not be performed at all at the time of maintenance because the structure is decomposed from the hot water supply pipe or hot water collection pipe when the strainer is replaced. In other words, in order to remove foreign substances in cold weather such as winter season, the boiler should be shut down and the hot water supply pipe or hot water recovery tube of the hot water distributor must be disassembled.
