Description

A gas central energy-saving water heater

technical field

The utility model relates to a water heater, in particular to a gas central energy-saving water heater.

Background technique

Hotels, restaurants, schools, institutions, and enterprises all need hot water or boiling water, so they need devices that generate hot water or boiling water. The existing hot water or boiling water devices have slow heating speed, low heat conversion efficiency, and high energy consumption. , But the utilization rate is low and other defects.

Contents of the invention

The utility model aims at the deficiencies in the prior art, and provides a gas central energy-saving water heater.

The utility model is realized through the following technical solutions: a gas central energy-saving hot water machine, including a casing, an inner tank, and an air extraction device, the inner tank is connected to an external water supply device, and a water supply device is provided between the external water supply device and the inner tank Valves, the bottom of the casing is provided with a gas channel and a sewage channel, the gas pipeline is provided with a gas valve, the bottom of the inner tank is provided with a gas fire row, the gas channel is connected to the gas fire row, and the inside of the inner tank is equipped with evenly distributed curved fire pipes. The upper and lower ends of the fire pipe are respectively sealed and connected with the upper and lower ends of the inner tank. There is a power distribution box inside the casing. The power distribution box is equipped with inner tank water temperature detection devices, water level detection devices, opening and closing gas valves, and water supply valves. control device.

Among them, the curved fire tubes after multiple bendings are preferably used, and the number can be determined according to the specific size of the inner tank. For a normal hot water machine, preferably 26 curved fire tubes are divided into two rows and evenly distributed in the Inside the liner.

As a preference for the above scheme, the bottom of the inner tank is provided with an inverted funnel-shaped sewage outlet, and the inverted funnel-shaped sewage outlet is connected to the sewage channel. Drain the scale.

As a preference of the above solution, an LCD display device connected to the power distribution box and a control button located below the LCD display device are provided on the surface of the casing.

The utility model has the advantages that: the device can timely monitor the temperature of the water in the inner tank, detect the water level in the inner tank in time through the water level detection device, and automatically determine whether to open or close the gas valve and the water supply valve according to the water temperature and water level. There is an LCD display device and control buttons on the casing, which can automatically control the water temperature according to the needs.

Detailed ways

Below in conjunction with specific embodiment the utility model is further described.

As shown in Figure 1 and Figure 2, a gas central energy-saving water heater includes a casing, an inner tank, and an air extraction device. The inner tank is connected to an external water supply device, and a water supply valve is provided between the external water supply device and the inner tank. There are gas passages and sewage passages at the bottom of the shell, gas valves on the gas pipes, gas fire row at the bottom of the inner tank, the gas channel is connected to the gas fire row, and there are two rows of twenty-six evenly distributed bends inside the inner tank. The fire pipe, the upper and lower ends of the curved fire pipe are respectively sealed and connected with the upper and lower ends of the inner tank. There is a power distribution box inside the casing. The power distribution box is equipped with a inner tank water temperature detection device, a water level detection device, and a gas The control device for valves and water supply valves. There is an LCD display device connected to the power distribution box on the surface of the casing and a control button located below the LCD display device. According to specific needs, the gas valve can be automatically opened or closed for heating or cooling. When the water level of the tank drops to a certain level, the water supply valve is automatically controlled for water supply or water cut-off.

In addition, there is an inverted funnel-shaped sewage outlet at the bottom of the tank bottom. The inverted funnel-shaped sewage outlet is connected to the sewage channel. Under the action of its own gravity and water flow, the scale gathers to the funnel mouth, and the scale can also be discharged while the sewage is being discharged.

The above descriptions are only preferred embodiments embodying the principles of the present invention, and do not limit the protection scope of the present invention. All equivalent changes and modifications made according to the present invention are within the scope of patents covered by the present invention.
