Description

Technical Field

[0001] The utility model relates to the field of heating equipment, in particular to an exposed top-water inlet and top-water return bathroom radiator. Background Art

[0002] The vertical pipes and horizontal pipes of the existing water-heating bathroom radiator equipment are all interconnected, and the inlet and return water ports are located at the lower ends of the vertical pipes on both sides. The tops of the vertical pipes are respectively provided with exhaust valves and plugs. In order to hide the inlet and return pipes of the existing exposed bathroom radiators, the inlet and return pipes are generally laid from the ceiling. When connecting the bathroom radiator, it is necessary to lead the pipes to the bottom end of the existing bathroom radiator and connect its inlet and outlet to allow the bathroom radiator to circulate and dissipate heat normally. However, the inlet and return pipes are led from the ceiling to the lower end of the heating equipment, which is a long distance and the exposed pipes are long. If they are installed openly, it will affect the appearance, and the installation is cumbersome and the workload of concealed installation is large. If the inlet and return pipes are directly connected to the top water outlet of the existing bathroom radiator vertical pipe, the internal water channel structure of the existing radiator is all interconnected. The hot water in the bathroom radiator is light in weight and accumulates in the upper part of the heating equipment, while the low-temperature water accumulates in the lower part. The low-temperature water in the lower part cannot be brought out from the top of the bathroom radiator, and water circulation cannot be achieved. Moreover, if the two top water outlets are occupied by the water inlet and return pipes, it is impossible to install an exhaust valve for exhaust, resulting in air blockage in the heating equipment and failure to achieve water circulation. The heating effect cannot be achieved. Utility Model Content

[0019] The beneficial effects of the utility model are:

[0020] The bathroom radiator is equipped with an independent upper return water riser, upper water inlet, and upper return water outlet. When laying exposed pipes from the ceiling downward, they can be directly connected to the water inlet and return outlet at the top of the bathroom radiator to circulate heat normally. This solves the problem of exposed pipes running from the ceiling to the bathroom radiator, which requires laying exposed pipes to the bottom of the bathroom radiator, which is a long distance, has long exposed pipe lengths, and is cumbersome to install. It also reduces the length of exposed pipes and the unsightly appearance of exposed pipes, making the decoration more beautiful and the installation more convenient.

[0021] The first vertical pipe, the second vertical pipe, the third vertical pipe and several horizontal heat dissipation pipes are arranged vertically. The upper end of the first vertical pipe is connected to the upper water inlet. The first vertical pipe and the second vertical pipe are connected to the several horizontal heat dissipation pipes. The bottom of the second vertical pipe and the third vertical pipe are connected. The upper end of the third vertical pipe is connected to the upper return water inlet. The top of the second vertical pipe or the first vertical pipe is also provided with an exhaust valve to discharge the gas in the bathroom radiator. When in use, the water inlet pipe is connected to the upper water inlet at the top of the bathroom radiator. The water flows from the upper water inlet through the upper water inlet transverse pipe to the first vertical pipe. The first vertical pipe is connected to the second vertical pipe through several horizontal heat dissipation pipes. The top of the second vertical pipe is provided with an exhaust to discharge the gas in the radiator. The heat dissipation circulates normally. After the heat dissipation cycle, the warm water gathers at the bottom of the bathroom radiator and is brought out to the upper return water transverse pipe through the bottom of the third vertical pipe. The upper return water inlet at the top is connected to the return water pipe to bring the warm water out of the radiator for heat exchange. The interior is equipped with independent upper water inlet and return risers, which are not connected to the heat dissipation pipes. The water channel connection structure design allows the exposed pipe to be directly connected to the top of the bathroom radiator for normal circulation and heat dissipation. This solves the problem of exposed pipes running from the ceiling to the bathroom radiator, which requires laying exposed pipes to the bottom of the bathroom radiator, which is a long distance, has long exposed pipes, and is cumbersome to install.

[0022] An upper water inlet transverse pipe is connected between the upper end of the first vertical pipe and the upper water inlet. The upper water inlet transverse pipe is arranged behind the uppermost heat dissipation transverse pipe. The left end of the upper water inlet transverse pipe is connected to the first vertical pipe, and the right end of the upper water inlet is connected to the upper water inlet. An upper return water transverse pipe is connected between the upper end of the third vertical pipe and the upper return water outlet. The upper return water transverse pipe is arranged behind the uppermost heat dissipation transverse pipe. The right end of the upper return water transverse pipe is connected to the third vertical pipe, and the left end of the upper return water transverse pipe is connected to the upper return water outlet. The establishment of the upper water inlet transverse pipe brings the upper water inlet and return water outlet together at the middle rear side of the radiator, making it easier for subsequent exposed installation to hide the exposed water inlet and return pipes in the same pipe groove, making the decoration more beautiful.

[0023] An adjusting valve core is set in the third vertical pipe, which utilizes the effective combination of the inner cavity and the valve core of the bathroom radiator, saves production costs, is more convenient to install, effectively adjusts the water flow rate, and then adjusts the heat dissipation to achieve the effect of regulating the indoor temperature.

[0024] An exhaust valve is installed at the top of the second vertical pipe. When the exposed pipe is connected to the water inlet and return port at the top of the bathroom radiator, the top of the second vertical pipe can also exhaust the air in the radiator, allowing it to circulate and dissipate heat better.
