Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a condensation atomization device and a gas water heater. Background Technology

[0002] Existing condensing gas water heaters produce weakly acidic condensate during operation. This condensate contains carbonic acid, nitrite, and sulfurous acid, which are corrosive. It requires a condensate collection box to collect the condensate, neutralizes it with alkaline filter media, and then drains it into the sewer via a pre-installed drain pipe in the user's home. The installation of this condensate drain pipe affects the aesthetics of the water heater. Users without a pre-installed drain pipe can either choose to drain the condensate through a separate drain pipe to the outside of the balcony, which not only affects the aesthetics of the water heater but also causes dripping from a height, or install a collection box on the outside of the water heater and manually empty the condensate periodically, which is inconvenient.

[0003] Therefore, there is an urgent need for a condensation atomization device to solve the above problems. Utility Model Content

[0041] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0042] Please refer to Figures 1-5This utility model provides a condensation atomizing device, including a shell, an atomizer 3, and a condensation heat exchanger 4. The shell contains a cavity; a water storage cavity 104 is located at the lower part of the cavity, and an exhaust cavity 105 communicating with the water outlet cavity 104 is located at the upper part of the cavity. The shell has an inlet port 101 and an outlet port 122 communicating with the exhaust cavity 105, and a condensate inlet port 106 communicating with the water storage cavity 104. The atomizer 3 is installed in the water storage cavity 104 to atomize the condensate in the water storage cavity 104. The condensation heat exchanger 4 is installed on the outside of the shell. The outlet port of the condensation heat exchanger 4 communicates with the inlet port 101, and a condensate drain port is located at the bottom of the condensation heat exchanger 4, communicating with the condensate inlet port 106.

[0043] The condensation atomization device provided by this utility model has a condensation heat exchanger 4 installed at the flue gas outlet of the main heat exchanger 9 of the gas water heater. The high-temperature flue gas from the main heat exchanger 9 enters the condensation heat exchanger 4 for heat exchange and forms low-temperature flue gas that enters the exhaust chamber 105. The condensate formed in the condensation heat exchanger 4 enters the water storage chamber 104 through the condensate drain port and the condensate inlet port 106. The atomizer 3 operates to atomize the condensate in the condensate atomization chamber. The water mist formed after atomization is discharged with the low-temperature flue gas through the exhaust chamber 105 to the flue gas outlet port 122, thereby realizing automatic treatment of condensate. Users do not need to clean the condensate regularly or install a condensate drain pipe to discharge the condensate. The structure is simple and compact.

[0044] Optionally, a mist-collecting hood 2 is also included. The mist-collecting hood 2 includes a housing 21 and a mist-collecting chamber 200 disposed within the housing 21. The housing 21 is disposed in the exhaust chamber 105 and is spaced apart from the inner wall of the exhaust chamber 105 to form an exhaust channel. The upper end of the mist-collecting chamber 200 is connected to the exhaust port 122, and the lower end of the mist-collecting chamber 200 is connected to the water storage chamber 104. By providing the mist-collecting hood 2, water mist is prevented from being discharged into the condensing heat exchanger 4 through the exhaust port 101. Specifically, when the low-temperature flue gas in the exhaust chamber 105 is discharged from the exhaust port 122, a negative pressure is formed at the exhaust port 122, causing the water mist at the exhaust port 122 to be discharged from the exhaust port 122 simultaneously. Specifically, the flue gas and water mist move along... Figure 1 The flow is in the direction indicated by the middle arrow.

[0045] Optionally, a smoke passage 22 is provided at the lower part of the cover 21. The smoke passage 22 connects the mist collection chamber 200 and the smoke exhaust channel, so that some low-temperature flue gas can enter the mist collection chamber 200 through the smoke passage 22, and drive the water mist in the mist collection chamber 200 to be discharged to the smoke outlet port 122, so that the water mist can be discharged more smoothly.

[0046] Optionally, the smoke passages 22 are evenly distributed on the periphery of the bottom of the cover 21.

[0047] Optionally, a first connecting part is provided on the periphery of the cover 21, and a second connecting part corresponding to the first connecting part is provided on the inner wall of the exhaust chamber 105. The first connecting part and the second connecting part are detachably connected, thereby realizing the stable installation of the fog cover 2 in the exhaust chamber 105.

[0048] Optionally, a smoke guide plate 23 is provided in the smoke exhaust channel near the smoke inlet port 101. The smoke guide plate 23 is located above or above the smoke inlet port 101. The smoke guide plate 23 has multiple smoke outlet holes 230 opened in the vertical direction. By setting the smoke guide plate 23 and setting multiple smoke outlet holes 230 on the smoke guide plate 23, the low temperature flue gas can flow evenly from the periphery of the cover 21 upwards, so that the flue gas can flow relatively evenly from the smoke passage hole 22 into various parts of the mist collection chamber 200, thereby driving the water mist located in various parts of the mist collection chamber 200 to be evenly discharged to the smoke outlet port 122.

[0049] Optionally, the outer casing includes an outer casing 11, a top cover 12, and a cover plate 13. A smoke inlet port 101 is located on the outer casing. A connection port 102 is located at the upper end of the outer casing. The top cover 12 includes a cover body 121, and a smoke outlet port 122 is located on the cover body 121. The cover body 121 covers the connection port 102 and connects to the outer casing 11. An installation port 103, communicating with a water storage chamber 104, is located at the lower part of the outer casing 11. The atomizer 3 is installed into the water storage chamber 104 through the installation port 103. The cover plate 13 covers the installation port 103 and is sealed to the outer casing 11. The separate outer casing consisting of an outer casing 11, a top cover 12, and a cover plate 13 facilitates both the installation of the smoke hood into the exhaust chamber 105 via the connection port 102 and the installation of the atomizer 3 into the water storage chamber 104 via the installation port 103.

[0050] Optionally, the outer casing 11 is integrally molded, which has a simple structure and good sealing effect.

[0051] Optionally, the top of the cover 21 is provided with a water mist outlet 201, and the bottom of the cover 21 is provided with a water mist inlet. The water mist inlet is connected to the water storage chamber 104. The water mist outlet 201 is set lower than the cover 121 so that the low-temperature flue gas in the exhaust channel can flow out to the exhaust port 122 through the gap between the water mist outlet 201 and the cover 121.

[0052] Optionally, the atomizer 3 includes an atomizer body 31, an atomizing plate 32 and an atomizing switch 33 disposed on the atomizer body 31. When the condensate water level in the water storage chamber 104 is higher than the atomizing switch 33, the atomizing switch 33 is triggered, the atomizer 3 operates, the atomizing plate 32 vibrates, and atomizes the condensate water into water mist; when the condensate water level in the water storage chamber 104 is lower than the atomizing switch 33, the atomizing switch 33 is not triggered, and the atomizer 3 stops operating.

[0053] Optionally, the atomizer 3 also includes a wire 34, on which a sealing ring 35 is fitted. The cover plate 13 is provided with a wire hole 130 corresponding to the wire 34. The wire 34 extends out of the outer shell from the wire hole 130. The sealing ring 35 is located between the wire 34 and the wire hole 130 to seal the gap between the wire 34 and the wire hole 130, preventing condensate in the water storage chamber 104 from overflowing from the gap.

[0054] Optionally, a liquid level sensor 6 is also included, which is installed in the exhaust chamber 105 and positioned below the smoke inlet port 101. When the atomizer 3 malfunctions, the condensate in the water storage chamber 104 will continue to rise and overflow from the water storage chamber 104. When the water in the water storage chamber 104 overflows to the liquid level sensor 6, the liquid level sensor 6 is triggered, which in turn causes the gas water heater to issue an alarm, indicating that the atomizer 3 has malfunctioned, and simultaneously shutting down the gas water heater to prevent the condensate from continuing to rise and flowing back into the main heat exchanger 9 of the gas water heater.

[0055] Optionally, the lowest point of both the flue gas outlet and the lowest point of the flue gas inlet of the condensing heat exchanger 4 are set higher than the condensate drain port. This allows the condensate inside the condensing heat exchanger 4 to collect at the condensate drain port and flow out.

[0056] Optionally, the lowest point of the flue gas outlet of the condenser heat exchanger 4 and the lowest point of the flue gas inlet of the condenser heat exchanger 4 are both set higher than the water storage chamber 104, so that the condensate in the condenser heat exchanger 4 can flow into the water storage chamber 104 by means of the communicating vessel principle, and at the same time, the condensate will not overflow from the condenser heat exchanger 4.

[0057] Optionally, it also includes a condensate collection box 51, which is located below the condensing heat exchanger 4. The inlet of the condensate collection box 51 is connected to the condensate drain port, and the outlet of the condensate collection box 51 is connected to the condensate inlet port 106.

[0058] Optionally, the condensate collection box 51 is also provided with filter media 52 for neutralizing the condensate.

[0059] Optionally, the system also includes a condensate inlet pipe 71 and a condensate outlet pipe 72. The upper end of the condensate inlet pipe 71 is connected to the condensate drain port, and the lower end of the condensate inlet pipe 71 is connected to the inlet of the condensate collection box 51. The condensate in the condensing heat exchanger 4 flows out through the condensate inlet pipe 71 into the condensate collection box 51. The lower end of the condensate outlet pipe 72 is connected to the outlet of the condensate collection box 51, and the upper end of the condensate outlet pipe 72 is connected to the condensate inlet port 106. The condensate in the condensate collection box 51 flows out through the condensate outlet pipe 72 into the water storage chamber 104.

[0060] Optionally, the inlet of the condensate collection box 51 is located at the upper end of the condensate collection box 51, and the outlet of the condensate collection box 51 is located at the lower end of the periphery of the condensate collection box 51.

[0061] Please refer to Figure 6 In another aspect, this utility model provides a gas water heater, including a main heat exchanger 9, a hot water exchange pipe passing through the heat exchanger, and the aforementioned condenser atomizing device. The flue gas inlet of the condenser heat exchanger is connected to the flue gas outlet of the main heat exchanger 9, and the flue gas outlet of the condenser heat exchanger is connected to the flue gas inlet port 101. The hot water exchange pipe includes a cold water section 81 and a hot water section 82. One end of the cold water section 81 is connected to the water supply pipe outside the gas water heater, and the other end of the cold water section 81 is connected to the water inlet of the condenser heat exchanger. One end of the hot water section 82 is connected to the water outlet of the condenser heat exchanger, and the other end of the hot water section 82 passes through the main heat exchanger 9 and is connected to a hot water point outside the gas water heater. The cold water in the cold water section 81 first undergoes preliminary heat exchange through the condenser heat exchanger, then enters the main heat exchanger 9 for final heat exchange before flowing out to the hot water point.

[0062] Optionally, it also includes a fan 10, which is located between the exhaust port of the main heat exchanger 9 and the inlet port of the condensing heat exchanger. The fan 10 is used to generate negative pressure to blow the high-temperature flue gas generated in the main heat exchanger 9 into the condensing heat exchanger, and then discharge the low-temperature flue gas after heat exchange in the condensing heat exchanger through the exhaust chamber 105 to the exhaust port 122, thereby discharging it to the outside of the gas water heater.

[0063] The above descriptions are merely some embodiments of this utility model.
