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] An exposed top-inlet and top-return bathroom radiator is internally equipped with independent top inlet pipes, top return pipes, top water inlet, and top return outlet. When laying exposed pipes from the ceiling downward, they can be directly connected to the top water inlet and return outlet of the bathroom radiator for normal circulation and heat dissipation. This solves the problems of requiring exposed pipes from the ceiling to the bathroom radiator to be connected to the bottom of the bathroom radiator, which is a long distance, has long exposed pipe lengths, and is cumbersome to install. It reduces the laying length of exposed pipes and the unsightly appearance of exposed pipes, making the decoration more beautiful and the installation more convenient.

The upper end of the first pipe is connected to the water inlet. The right vertical pipe includes a third pipe and a fourth pipe arranged vertically.

Several heat dissipation transverse pipes are horizontally connected between the second pipe and the fourth pipe. When in use, the water inlet pipe is connected to the upper water inlet of the bathroom radiator. Water flows from the upper water inlet into the first pipe. The first pipe is connected to the bottom of the second pipe and enters the second pipe. The second pipe is connected to the fourth pipe through several heat dissipation transverse pipes. Gas is discharged from the top of the fourth pipe. The fourth pipe is connected to the bottom of the third pipe. The warm water gathered at the bottom of the bathroom radiator after the heat dissipation cycle is brought out to the upper return water outlet at the top through the bottom of the third pipe and connected to the return pipe. The warm water after heat dissipation is brought out of the radiator for heat exchange. The internal structure is designed with independent upper inlet and return water pipes. The upper inlet and return water outlet are not interconnected with the heat dissipation pipe. The water channel connection structure design allows the top of the bathroom radiator to be directly connected to the normal circulation and heat dissipation when the exposed pipe is laid. It solves the problems of exposed pipes from the ceiling to the bathroom radiator, which need to be laid to the bottom of the bathroom radiator, the distance is long, the exposed pipes are long, and the installation is complicated.

The left end of the upper water inlet transverse pipe is connected to the first 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 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 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 and the upper return water transverse pipe brings the upper water inlet and the upper return water outlet together at the middle and rear side of the radiator, making it convenient to subsequently hide the radiator water inlet and return pipes in the same pipe groove and extend them to the ceiling, making the decoration more beautiful.

[0022] By setting a regulating valve core in vertical pipe 6 and vertical pipe 7, the effective combination of the inner cavity and the valve core of the bathroom radiator is utilized, which saves production costs and makes installation more convenient. It can effectively adjust the water flow rate and then adjust the heat dissipation to achieve the effect of regulating the indoor temperature.

[0023] The exhaust valve is provided at the upper end of the second pipe or the fourth pipe. When the exposed pipe is connected to the water inlet and return port at the top of the bathroom radiator, the top can simultaneously exhaust the air in the radiator, allowing it to circulate and dissipate heat better.
