Abstract
Description
Technical Field
[0001] This utility model belongs to the field of household appliance technology, specifically relating to a condensing gas water heater and its atomizing water removal mechanism. Background Technology
[0002] Condensing gas water heaters are a type of highly efficient and energy-saving water heater equipment that produces acidic condensate during operation.
[0003] Currently, atomizing acidic condensate and discharging it with flue gas is one of the trends in condensate treatment. The applicant previously disclosed a condensate treatment device for gas water heaters and the water heater itself, including a water collection chamber and an atomizing head. The atomizing head has a three-way structure, including an air inlet connected to an air pump, a water inlet connected to the water collection chamber, and a mist outlet facing the exhaust pipe of the gas water heater. The air pump compresses air and pumps it into the air inlet of the atomizing head. Condensate in the water collection chamber enters the water inlet of the atomizing head through the water inlet pipe, and the water mist sprayed from the mist outlet is discharged through the exhaust pipe. Practical application has revealed that for some high-flow condensing gas water heaters, the distance between the water collection chamber and the atomizing head is relatively far, resulting in a longer condensate delivery distance compared to conventional condensing gas water heaters. This leads to larger or uneven atomized particles, resulting in reduced atomization efficiency. Therefore, to address these problems and technical requirements, a new structure needs to be developed to efficiently discharge condensate from high-flow condensing gas water heaters. Summary of the Invention
[0004] To address the aforementioned problems, the purpose of this utility model is to provide a condensing gas water heater and its atomizing water removal mechanism, which uses a needle-type atomizing head combined with a pressure pump to atomize the condensate water, without being limited by the water delivery distance, and can efficiently discharge the condensate water.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A condensing gas water heater includes a condenser, a flue pipe, and an atomizing mechanism; the condenser is connected to the flue pipe; the atomizing mechanism is located on the flue gas flow path formed by the connection between the condenser and the flue pipe; the condenser includes a water storage box; the atomizing mechanism includes a needle-type atomizing head and a pressure pump; the water inlet of the needle-type atomizing head is connected to the water storage box through the pressure pump.
[0007] A water atomizing mechanism for a condensing gas water heater includes a condenser, a flue pipe, and an atomizing mechanism; the condenser is connected to the flue pipe; the atomizing mechanism is located on the flue gas flow path formed by the connection between the condenser and the flue pipe; the condenser includes a water storage box; the atomizing mechanism includes a needle-type atomizing head and a pressure pump; the water inlet of the needle-type atomizing head is connected to the water storage box through the pressure pump.
[0008] In actual production, a section of pipe is left on the upper surface of the condenser. The exhaust pipe can be directly connected to the pipe on the upper surface of the condenser, or it can be connected through an additional pipe. When the exhaust pipe is directly connected to the pipe on the upper surface of the condenser, the atomizing mechanism can be located inside the pipe on the upper surface of the condenser or inside the exhaust pipe. When the exhaust pipe is connected to the pipe on the upper surface of the condenser through an additional pipe, the atomizing mechanism can be located inside the pipe on the upper surface of the condenser, inside the exhaust pipe, or inside the additional pipe. Preferably, the exhaust pipe is connected to the pipe on the upper surface of the condenser through an additional pipe, and the atomizing mechanism is located inside the additional pipe. With this structure, the original internal structure of the condensing gas water heater can be maintained.
[0009] Furthermore, the water storage box is either the bottom part of the condenser or a separate container connected to the condenser.
[0010] Preferably, the water storage box is equipped with a filter and / or a water level sensor. The filter is used to filter impurities in the condensate to prevent clogging of the atomizing head's mist outlet. The water level sensor is used to monitor the condensate water level in the storage box. When the set water level is reached, a water level signal is transmitted to the central controller of the condensing gas water heater. The central controller then controls the start and stop of the atomizing head to prevent it from running for extended periods and to extend the service life of the components.
[0011] Furthermore, the striker-type atomizing head has a two-way structure, including a water inlet connected to the water storage box and a mist outlet. Compared to a two-fluid atomizing head driven by an air pump, the striker-type atomizing head has only one pipe connected to it, which can reduce obstruction of the flue gas.
[0012] Preferably, the atomizing head of the impact pin is positioned so that the direction of the mist output is consistent with the direction of the flue gas flow, which facilitates the flue gas carrying away the atomized condensate and discharging it through the exhaust pipe.
[0013] Furthermore, the water inlet of the atomizing head is connected to the water outlet of the pressure pump via a water pipe; the water inlet of the pressure pump is connected to the water storage box via a water pipe.
[0014] Preferably, an auxiliary fan is provided on the flue gas flow path formed by the connection between the condenser and the exhaust pipe to accelerate the exhaust gas and carry out the atomized condensate, thereby increasing the discharge speed of the condensate.
[0015] As is common knowledge, the condensing gas water heater also includes a combustion chamber, a combustion control fan, and other basic components of the condensing gas water heater, such as a central controller, water pipes, and a heat exchanger. The combustion chamber and combustion control fan are also basic components of the condensing gas water heater. The combustion control fan and auxiliary fan are controlled separately, and the connection method between the specific components and the control method of the central controller are conventional technologies.
[0016] Due to the application of the above technical solutions, the beneficial effects of this utility model compared to the prior art are as follows: Users do not need to frequently empty water or reserve additional condensate drain outlets. By setting up an atomizing mechanism, condensate is transformed into atomized condensate for discharge. In particular, this utility model uses a needle-type atomizing head combined with a pressure pump to atomize the condensate, which is not limited by the water delivery distance and can efficiently discharge the condensate, making it applicable to high-flow-rate condensing gas water heaters. Furthermore, compared to a two-fluid atomizing head driven by an air pump, the needle-type atomizing head only has one pipe, reducing obstruction to the flue gas. Further, by providing an auxiliary fan in the flue gas flow path formed by the connection between the condenser and the exhaust pipe, the flue gas can be accelerated to carry the atomized condensate out, increasing the condensate discharge speed.
