Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a condenser and a gas water heater device. Background Art

[0002] The condenser is generally connected to the fan of the gas water heater. The heat exchange tubes are arranged inside the condenser and exchange heat with the high-temperature flue gas to form condensed water. Since the condensed water is acidic, it is easy to corrode the condenser. To solve this problem, a condensation neutralizer is generally used. The condensed water is connected to the condensation neutralizer through a connecting pipe. An alkaline neutralizing substance is installed in the condensation neutralizer, and the condensed water is discharged from the whole machine after being neutralized. Although the acidity of the condensed water can be neutralized, the neutralized condensed water still affects the condenser, making the metal shell and internal metal components of the condenser prone to rust. Content of the Utility Model

[0017] Referring to Figures 1 to 5 , a condenser of the present invention includes a housing 10, a cover plate 12, and a condensation heat exchanger 11 arranged in the housing 10. An electric heating element 20 is provided at the bottom of the housing 10. The top of the housing 10 is open, and the cover plate 12 is connected to the housing 10 to seal the top of the housing 10. The open top of the housing 10 facilitates the installation and disassembly of the condensation heat exchanger 11 and the electric heating element 20. The electric heating element 20 provided at the bottom of the housing 10 can heat the condensed water until it is completely vaporized, avoiding the rusting of metal parts. There is no need to use a condensation neutralizer, saving costs. And the process of vaporizing the condensed water is an exothermic process, which can further transfer heat to the condensation heat exchanger 11, improving the thermal efficiency of the whole machine and saving energy.

[0018] As shown Figure 2 in the figure, it further includes a sealing ring 13, and the sealing ring 13 is arranged at the connection between the outer shell 10 and the cover plate 12 and abuts against the outer shell 10 and the cover plate 12 respectively to improve the sealing performance.

[0019] As shown Figure 3 and Figure 4 in the figure, the electric heating element 20 is arranged in a rectangular or disc shape, and it can also be of other shapes.

[0020] In some embodiments, an installation groove is provided at the bottom of the outer shell 10, and the electric heating element 20 is arranged in the installation groove, which is convenient for the installation and fixation of the electric heating element 20. The electric heating element 20 can be directly in contact with the condensed water and heat it to vaporize.

[0021] As shown Figure 5 in the figure, in some embodiments, it further includes a heat conducting plate 14, and the heat conducting plate 14 is arranged in the installation groove and above the electric heating element 20, which plays a role in heat conduction, can avoid the contact between the electric heating element 20 and the condensed water, and improve the reliability.

A smoke exhaust port 110 and an air inlet 120 communicated with the blower are respectively provided on the outer shell 10, and a cold water inlet 121 and a warm water outlet 122 respectively communicated with the condensation heat exchanger 11 are provided on the cover plate 12. The warm water outlet 122 is communicated with the water inlet end of the main heat exchanger. A plurality of liquid level sensors 30 (such as low, medium and high liquid level sensors 30) respectively electrically connected to the controller are arranged in the outer shell 10 at different liquid level heights. The controller adjusts the power of the electric heater in real time according to the liquid level height of the condensed water in the outer shell 10, so as to adjust the vaporization speed of the condensed water. For example, when the high liquid level sensor 30 detects the water level, the controller controls the electric heating element 20 to heat with high power to accelerate the vaporization of the condensed water. When the water level becomes low, the controller controls the electric heating element 20 to heat with a smaller power until all the condensed water is vaporized, and then the controller controls the electric heating element 20 to stop working, saving electric energy while achieving the vaporization purpose.
