Description

Technical Field

[0001] This utility model relates to the field of air source water heater technology, specifically an antifreeze air source water heater. Background Technology

[0002] Currently, there are three common types of water heaters on the domestic market: gas water heaters, electric water heaters, and solar water heaters. Gas water heaters may emit toxic gases due to incomplete combustion during use, which can cause safety accidents. Electric water heaters are bulky, take up a lot of indoor space, are prone to limescale buildup, waste a lot of electricity, and are prone to electrical leakage. Solar water heaters are complicated to install, and improper installation can affect the appearance and quality of the house and the city's urban landscape.

[0003] Regarding air source heat pump water heaters, refer to patent number CN208222834U, a low-temperature resistant and freeze-proof air source heat pump water heater, which can adapt to low-temperature and cold weather, especially in the severe cold weather of Northeast China, providing strong heating, energy saving and environmental protection, and is suitable for hotels, universities, guesthouses, hospitals, etc.

[0004] However, in the air source heat pump water heaters mentioned above, the fins on the outside of the fan in the extraction chamber are generally fixed. As the extraction chamber continuously draws air from the outside, the airflow will enter the extraction chamber in a continuous straight line. Therefore, some impurities and dust will enter the extraction chamber, thus affecting the safety of the extraction chamber.

[0005] Therefore, we propose an antifreeze air source water heater. Utility Model Content

[0013] Preferably, the canopy and the roof are arranged in a stepped manner, and the slot is horizontally aligned with the roof.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides an antifreeze air source water heater, which has the following beneficial effects:

[0016] 1.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-4 An antifreeze air source water heater includes a water heater body 1. An air extraction chamber 2 is fixedly installed on the front surface of the water heater body 1. A fan blade body 3 is rotatably installed on the inner surface of the air extraction chamber 2. Electric telescopic rods are fixedly installed on both the left and right sides of the upper surface of the air extraction chamber 2. A plurality of rotating rods 5 are rotatably arranged between the left and right inner walls of the air extraction chamber 2. A lever 6 is fixedly connected to the outer surface of the plurality of rotating rods 5. Gears 7 are fixedly installed at both ends of the plurality of rotating rods 5. An inner groove 8 is opened on the front surface of the air extraction chamber 2. A sliding groove 9 is opened on both the left and right surfaces of the inner groove 8. A slot hole 10 is opened on both the left and right inner walls of the air extraction chamber 2. A sliding plate 11 is slidably arranged on both the left and right inner walls of the inner groove. A toothed plate 12 is fixedly connected to the rear surface of the sliding plate 11.

[0027] Specifically, through the cooperation between the water heater body 1, the air extraction chamber 2, the fan blade body 3, the electric telescopic rod 4, the rotating rod 5, the lever 6, the gear 7, the inner groove 8, the sliding groove 9, the slot 10, the sliding plate 11, and the toothed plate 12, the lever 6 on the outside of the fan in the air extraction chamber 2 of the air source water heater can be intermittently flipped and blocked to prevent the air drawn into the air extraction chamber 2 from flowing in a straight line, thereby reducing the entry of dust and impurities into the air extraction chamber 2 and ensuring the safe use of the air source water heater's air extraction chamber 2.

[0028] In this embodiment: the output end of the electric telescopic rod 4 is fixedly connected to the upper surface of the corresponding side slide plate 11, and the slide plate 11 and the slide groove 9 are slidably arranged accordingly.

[0029] Specifically, the electric telescopic rod 4 can drive the slide plate 11 to slide horizontally up and down within the slide groove 9.

[0030] In this embodiment: the toothed plate 12 meshes with the gear 7, and the rotating rod 5 rotates in a corresponding manner with the slot 10.

[0031] Specifically, the toothed plate 12, through the up-and-down movement of the slide plate 11, can engage the gear 7 to rotate the rod 5 and the paddle 6 in both directions.

[0032] Working principle: When the water heater body 1 circulates odorous air through the fan blade body 3 in the air extraction chamber 2, the two electric telescopic rods 4 at the top of the air extraction chamber 2 drive the sliding plates 11 on both sides to cooperate with the sliding grooves 9, and slide stably up and down in the inner groove. At the same time, the sliding plates 11 drive the toothed plates 12 to mesh with the gears 7 on both sides of the rotating rod 5, so that the rotating rod 5 drives the paddle 6 to rotate in both directions in the slot 10. This can ensure that the operation of the fan blade body 3 in the air extraction chamber 2 is not affected, while reducing the amount of dust and impurities entering the air extraction chamber 2 through straight flow. It can also make the air entering the air extraction chamber 2 swing and flow, thereby ensuring stability.

[0036] Specifically, through the cooperation between the support legs 13, the canopy 14, the canopy 15, and the slot 16, the top of the air source heat pump can be protected by a tiered canopy 14, thus protecting the air source heat pump water heater.

[0037] In this implementation plan: the canopy 14 and the roof 15 are arranged in a stepped manner, and the slot 16 is arranged horizontally corresponding to the roof 15.

[0038] Specifically, the canopy 14 and the roof 15 work together to form a stepped protective shield, and the slot 16 can reduce the material consumption of the canopy 14.

[0039] Working principle: When the water heater body 1 is in operation, the support legs 13 at the top of the water heater body 1 support the canopy 14 and the roof 15 on the top of the water heater body 1 to protect the water heater. The slot 16 can reduce the weight of the canopy 14. The stepped canopy 14 and the roof 15 can effectively protect the water heater body 1 in rainy or snowy weather.
