Description

Distributor with integrated meter}

The present invention relates to a meter integrated dispenser.

In general, a bathtub, a washbasin, and a toilet seat requiring water are installed in bathrooms of buildings such as apartments or villas, and water is supplied by burying water supply pipes in walls or floors of buildings.

And a distribution pipe connecting each water supply pipe supplying water to the bathtub, washbasin and toilet seat is installed.

The distribution pipe is built into the floor or wall of the building by a pit box buried in the floor or wall, and serves to distribute water supplied to the water supply pipe to a bathtub or washbasin.

When the distribution pipe is buried in the floor of a building, if a defect such as rupture occurs, the room floor or floor must be broken down and inspected individually, and after repair work, it must be buried in the room floor or floor again, so the work is very difficult. Since there are problems such as inconvenience, in recent years, a method of embedding in a wall near each demand place such as a bathroom or toilet has been adopted. Of course, the distribution pipe is accommodated in the burial box and buried in the wall.

On the other hand, a meter for measuring water usage is connected to the pipe, and since this meter is accommodated in a meter box separate from the distributor and installed on an external wall, there is a problem in that the meter freezes and bursts in winter when the temperature is low.

In addition, in order to install the meter box separately from the distributor box, since the pipe must be installed separately, it not only causes trouble in construction, but also has various problems such as an increase in the amount of pipe used and an increase in construction cost.

4 is a front view showing the inside of a meter-integrated dispenser according to a third embodiment of the present invention.

The meter-integrated distributor according to the present embodiment further includes a heat pipe module 70 connecting the cumulative opening/closing valve 41 and the cold water meter 20.

Since the heat pipe module 70 transfers heat by moving a working fluid, maintenance is not required.

A heat pipe is a heat exchanger that efficiently transfers heat between interfaces of two solids by integrating the principles of thermal conductivity and phase transition.

Since the working fluid of the heat pipe is used to prevent the chilled water meter 20 from freezing, ammonia (213-373K), alcohol (methanol (283-403K) or ethanol (273-403K)) having a lower freezing point than water can be used.

The heat pipe module 70 includes a first flow path 71 and a second flow path 72 through which the working fluid moves, and the working fluid circulates through the first flow path 71 and the second flow path 72. configured to be able to

When the working fluid circulates through the first flow path 71 and the second flow path 72, it can circulate through condensation-expansion-evaporation. ) can be moved.

The heat pipe module 70 includes a protective case 76 disposed to surround the cold water meter 20, a first flow path 71 and a second flow path 72 through which the working fluid flows, and one end of the heat pipe module 70 is formed. It includes a heat pipe body 73 coupled to the cumulative opening/closing valve 41 to receive heat and the other end coupled to the protective case 76 to transfer heat.

An installation hole 75 penetrating the partition plate 17 in a vertical direction is formed, and the heat pipe body 73 is disposed to pass through the installation hole 75 .

One end of the heat pipe body 73 is disposed in the upper space 10a, and the other end is disposed in the lower space 10b.

The inside of the protective case 76 may be filled with a liquid or electrolyte having a lower freezing point than water and a large heat capacity, which is defined as a heat storage material 77 in the present embodiment.

The heat accumulation material 77 may be salt water in which salt is dissolved in a high concentration.

The working fluid exchanges heat with the heat storage material 77 inside the protective case 76, and in this process, the heat of the working fluid may be stored in the heat storage material 77.

In this embodiment, the salt water may be formed at a concentration of 50 permil to 100 permil, and through this, the heat transferred from the heat pipe body 73 can be effectively accumulated to prevent the chilled water meter 20 from freezing and bursting.

In particular, in this embodiment, the hot water meter 30 side and the heat pipe module 70 are not connected, and the cold water meter 20 freezes and breaks using waste heat from the calorimeter 40 disposed in the upper space 10a. used to prevent

When the hot water supplied from the district heating passes through the accumulating calorimeter 40, the user is charged a fee, but when it does not pass through the accumulating calorimeter 40, the user is not charged.

That is, even if the heat pipe module 70 exchanges heat with the accumulative opening/closing valve 41, which is the input side of the accumulating calorimeter 40, and the temperature of the accumulating opening/closing valve 41 is slightly lowered, the lowered hot water is stored in the accumulating calorimeter 40. , there is no difference in the fee charged to the user.

Since this embodiment does not use an electric heater such as a heater, and uses the heat of supplied hot water to prevent freezing of the cold water meter, the reliability of the installation structure is very high and the possibility of repair or damage is very low.

In addition, since the heat pipe module 70 transfers heat while the working fluid continuously flows even in a situation where hot water and cold water do not flow, there is an advantage in that it can be operated regardless of whether water is used or not.

On the other hand, it is okay to add the air circulation structure through the fan of the second embodiment.

Since the rest of the configuration is similar to that of the first embodiment, a detailed description thereof will be omitted.

5 is a front view showing the inside of a meter-integrated dispenser according to a fourth embodiment of the present invention.

Unlike the third embodiment, in the meter-integrated distributor according to the present embodiment, the second heat pipe module 170 connecting the cold water flow control valve 24 and the hot water flow control valve 34 is further disposed.

To differentiate from the second heat pipe module 170, the heat pipe module 70 of the third embodiment is defined as the first heat pipe module 70.

The second heat pipe module 170 may have the same structure as the first heat pipe module 70 .

The second heat pipe module 170 connects the hot water flow control valve 34 and the cold water flow control valve 24 to provide waste heat from the hot water flow control valve 34 to the cold water flow control valve 24, Through this, the temperature of the cold water flow control valve 24 may be increased.

One end 171 of the second heat pipe module 170 is connected between the cold water flow control valve 24 and the cold water meter 20, and the other end 172 of the second heat pipe module 170 controls the flow rate of hot water. It is connected between the control valve 34 and the hot water meter 30.

A temperature transmitted through the second heat pipe module 170 may be lower than a temperature transmitted through the first heat pipe module 70 .

In winter, hot water supplied indoors may be continuously circulated even when hot water is not supplied from the outside. The second heat pipe module 170 may increase the temperature of the cold water meter 20 by using waste heat of hot water circulating indoors.

The second heat pipe module 170 supplies heat between the cold water flow control valve 24 and the cold water meter 20 to quickly raise the temperature of the heat storage material 77, and the heat storage material 77 ) can be minimized.

Since the rest of the configuration is similar to that of the third embodiment, a detailed description thereof will be omitted.

In the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments and should not be defined, but should be defined by not only the scope of the claims to be described later, but also those equivalent to the scope of these claims.
