Description

Technical Field

[0001] The patent of this invention relates to the technical field of heating and hot water heaters, specifically a rainproof and evaporation-proof self-exhaust gas heating and hot water heater. Background Art

[0002] Winter heating demand in southern my country is increasing rapidly, and a heating system suitable for the southern climate is a small split-unit hot water radiator heating system. Like split-unit air conditioners, split-unit hot water heating systems consist of an outdoor unit and an indoor unit. The outdoor unit, a small, high-efficiency gas-fired hot water heater, is a key component of the split-unit heating system and must be installed outdoors, outside the room being heated. The hot water radiator is installed indoors. Currently, gas-fired hot water heaters use the same exhaust structure as household gas-fired wall-mounted boilers or gas-fired water heaters. The smoke collection and exhaust are located above the heater, with the exhaust pipe extending from the top of the heater housing. However, the installation location of gas-fired hot water heaters differs from that of household gas-fired wall-mounted boilers or gas-fired water heaters, requiring consideration for outdoor installation. When installing gas-fired hot water heaters outdoors, rain protection is essential. Therefore, the exhaust vent should not be located on the top of the heater housing, but rather on the side of the upper portion. This is one of the background technologies of this patent. Secondly, the water inlet of current gas-fired heating and water heaters is located on the top of the housing, which doesn't meet rain protection requirements and needs to be relocated to the upper side. Furthermore, the presence of a smoke exhaust pipe and a water inlet extending from the top is aesthetically pleasing. To ensure that gas-fired heating and water heaters are rainproof and aesthetically pleasing when installed externally, and to facilitate the growing adoption of split-unit room heating systems in southern China during winter, it was necessary to develop a rainproof, aesthetically pleasing gas-fired heating and water heater. Summary of the invention

[0003] The purpose of the present invention is to provide a rainproof and evaporation-proof self-exhaust gas heating water heater to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solution: a rain-proof and evaporation-proof self-exhausting gas heating radiator, comprising a radiator housing, wherein a smoke exhaust port and a water injection pipe are provided on the upper side of the radiator housing, a smoke collecting hood is provided in the inner cavity of the radiator housing, the smoke collecting port of the smoke collecting hood is opened at the lower part and sleeved on the smoke outlet of the gas heat exchanger, the smoke exhaust port of the smoke collecting hood is opened on the left side and inserted into the smoke exhaust port fixing frame on the upper left side of the inner cavity of the gas heating radiator housing, the water injection pipe is a pluggable horizontal square pipe provided on the upper right side of the radiator housing, the right end plate of the square pipe is sealed, the left end is open, and a water injection port is opened on it. The water injection pipe penetrates through the upper part of the right side of the gas heating radiator housing and is inserted into the water injection sleeve from the outside. The left end of the horizontal water injection sleeve is blocked, the lower part of the left end is open, and a small round pipe is welded at the opening. The small round pipe penetrates through the expansion water tank in the inner cavity of the gas heating radiator from the upper part and is inserted into the water seal cup. The water seal cup is welded at the top of the inner cavity of the expansion water tank, and a notch is opened on the upper edge of the water seal cup. The right end of the water injection sleeve is inserted into the water injection pipe fixing frame on the upper right part of the inner cavity of the gas heating radiator housing.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the gas heating radiator has a rain-proof function and can be hung outdoors for use. At the same time, the water seal in the expansion water tank can greatly reduce the evaporation loss of hot water, thereby reducing the number of water injections.

[0014] Next, the technical solutions in the embodiments of the invention patent will be described clearly and completely in conjunction with the embodiments of the invention patent Figure 2 , it is obvious that the described embodiments are only a part of the embodiments of the invention patent, rather than all the embodiments. Based on the embodiments in the invention patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the invention patent.

[0015] Please refer to Figure 2 , the invention patent provides a rainproof and waterproof technical solution: a rainproof, anti-evaporation and self-exhausting gas heating radiator, including the outer shell 18 of the radiator. The upper part of the left side of the outer shell 18 of the radiator is provided with a smoke exhaust port 22, and the upper right side is provided with a drawer-type water injection pipe 6. The drawer-type water injection pipe 6 is only pulled out outward during water injection until the water injection port is exposed for water injection, and is received in the water injection sleeve 4 at other times, and the right end face is flush with the right side face of the outer shell 18 of the radiator. When it rains, there is no opening or gap on the top surface of the outer shell 18 of the radiator, and the rainwater will flow along line A and be discharged outside the outer shell 18 of the radiator without entering the interior of the radiator, thus playing a rainproof role. Regarding waterproofing, there are two places in the radiator where condensate will be generated. One is that the main component of the combustion products of gas, water vapor, will condense into water when encountering cold air, and the other is that the water in the expansion tank 3 will evaporate due to high temperature, and the vapor will also condense into water when encountering cold at the right end of the water injection sleeve 4. In the invention patent, the fixed frame 23 not only fixes the smoke collecting hood 1, but also induces the condensed water to be discharged outside the outer shell 18 of the radiator along path B. The condensed water at the right end of the water injection sleeve 4 will drip into the fixed frame 5 of the water injection sleeve 4 and be discharged outside along the gap between the end face of the water injection pipe 6 and the outer shell 18 of the radiator along path C.

[0016] Still please refer to Figure 2, this invention patent provides an anti-evaporation self-exhaust technical solution: a rain-proof and anti-evaporation self-exhaust gas heating radiator, including an expansion tank 3, and a water seal cup 7 is provided at the upper part of the inner cavity of the expansion tank 3. Due to the condensation of water vapor, whether it condenses in the water seal cup 7 or the reverse flow of condensation in the water injection sleeve 4, water will form a water seal in the water seal cup 7. The water vapor in the expansion tank 3 is dissipated from the right end through the tiny gap between the water injection pipe 6 and the water injection sleeve 4, and the water seal can prevent a large amount of directly dissipated water vapor evaporated in the expansion tank 3. When the water level in the expansion tank 3 rises, the air pressure accumulated in area D will increase, and the air will pass through the water seal and enter area E, and finally automatically discharge from the gap between the water injection sleeve 4 and the water injection pipe 6.

[0017] Although the embodiments of the invention patent have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the invention patent. The scope of the invention patent is defined by the appended claims and their equivalents.
