Detailed Description

The present invention is illustrated by the following examples, but the present invention is not limited to these examples. To the embodiment of the present invention, modify or replace some technical features, without departing from the spirit of the present invention, it should be covered in the technical solution scope of the present invention.

Referring to fig. 1-4 and showing the utility model discloses a drain pan subassembly, including drain pan 1 and division board 2, division board 2 detachable installs on drain pan 1 with form air cavity 3 between the division board 2, the degree of depth of air cavity 3 is 8-15mm form air inlet district 4 on the drain pan 1 form air outlet district 5 on the division board 2 in the air cavity 3 air inlet district 4 with form air inlet channel between the air outlet district 5, air inlet channel is the shape of buckling.

In the gas water heater, a certain amount of air is needed for gas combustion, so that external air needs to be introduced through the bottom shell 1, the combustion requirement of a system is met, and the introduction of the air easily causes air flow disturbance, so that noise is generated. In order to reduce the noise that this process produced, the utility model provides a drain pan 1 subassembly drain pan 1 with form air cavity 3 between the division board 2, just air cavity 3's degree of depth is 8-15mm, avoids air cavity 3 degree of depth too shallow and causes the air to be difficult to get into, also avoids air wall degree of depth too deep and causes the air to get into too much, influences gas heater's gas normal combustion. When air enters through the air inlet area 4 of the bottom shell 1, the air passes through the air cavity 3 for buffering and then flows out through the air outlet area 5, so that noise caused by air flow disturbance due to air flow entering is avoided.

The air inlet wind channel is the shape of buckling, makes the air be in after the air inlet district 4 of drain pan 1 gets into obtain effectual buffering in the air cavity 3, the air inlet district 4 is in projection on the division board 2 with the air-out district 5 does not overlap, avoids the air inlet district 4 to be in projection on the division board 2 with the air-out district 5 overlaps and leads to the air to flow from the air-out district 5 perpendicularly after getting into from the air inlet district 4, does not obtain effectual buffering in the air cavity 3, forms great noise.

In some embodiments, the air cavity 3 may be formed by pressing a certain height outward on the bottom case 1. In some embodiments, the air cavity 3 may be formed by pressing a certain height on the partition plate 2 in a direction away from the bottom case 1. In some embodiments, the air cavity 3 may be formed by pressing a certain height outward on the bottom case 1 and pressing a certain height in a direction away from the bottom case 1 on the partition plate 2.

In this embodiment, the air inlet area 4 is disposed at a position of the bottom case 1 close to the center line, and the air outlet area 5 is disposed at the left and right sides of the partition board 2.

In other embodiments, the air inlet area 4 may be disposed at a position projected on the partition plate 2 at a center position of the partition plate 2, and the air outlet areas 5 are disposed at four corners of the partition plate 2.

The air inlet area 4 comprises a plurality of air inlet holes, the air inlet holes are formed in the bottom shell 1 in the vertical direction, the air outlet area 5 comprises a plurality of air outlet holes, and the air outlet holes are formed in the partition plate 2 in the transverse direction.

The peripheral edge of the air inlet hole extends outwards to form an air inlet and guiding structure, and the peripheral edge of the air outlet hole extends outwards to form an air outlet and guiding structure. The air inlet air guide structure's setting makes the air follow the air inlet air guide structure is followed inside the fresh air inlet of air inlet district 4 enters into gas heater, effectively reduces the air inlet noise, the setting of air-out air guide structure makes the air follow the air-out air guide structure and follows the exhaust vent of air-out district 5 flows to gas heater's combustion system in, effectively reduces the air-out noise.

The partition board 2 is provided with a fixing lug 21, the bottom case 1 is provided with a fixing clamping groove 11, and the partition board 2 is detachably mounted on the bottom case 1 through the matching of the fixing lug 21 and the fixing clamping groove 11. In order to realize simple installation of the partition board 2, the air partition board 2 is provided with the upper fixing lugs 21, and the bottom shell 1 is provided with the fixing clamping grooves 11 on the main body, so that the air partition board can be quickly inserted and connected, is convenient to install and is also convenient to disassemble and maintain. In this embodiment, the fixing clamp slot 11 is arranged at the upper end of the air cavity 3, so that the air cavity 3 is not affected.

The improved structure of the LED lamp is characterized in that side baffles are further arranged at the left end and the right end of the bottom shell 1, a face shell is further arranged above the bottom shell 1, and the face shell is connected with the side baffles so as to connect the bottom shell 1 with the face shell together.

And a sealing strip is also arranged at the joint of the face shell and the side baffle.

When the whole gas water heater normally operates, noise generated by operation needs path transmission, and numerous noise test data show that the matching surface of the bottom shell 1 and the face shell of the gas water heater is one of key noise transmission paths, and the noise is prevented from being transmitted from the matching surface of the shell, so that a sealing strip is arranged at the connecting part of the side baffle plates at the two sides of the bottom shell 1 and the face shell, and the sealing strip enables a closed cavity to be formed between the face shell and the bottom shell 1, and the noise generated by the operation of the whole gas water heater can repeatedly vibrate in the closed cavity, and the noise energy is attenuated after multiple times of vibration, so that the noise generated by the operation is effectively controlled in the transmission process, and passive noise reduction is realized.

The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
