Description

Technical Field

[0001] The utility model relates to the technical field of gas equipment, in particular to a wind-resistant water heater. Background Art

[0002] Existing gas water heaters are usually installed indoors or in a semi-open environment, and the probability of the flame of the internal burner being extinguished due to the influence of wind flow is not high. Therefore, the air inlet of the existing gas water heater is usually arranged at the bottom of the shell to facilitate the wind flow to enter the shell from the air inlet to provide the burner with the air required for combustion. However, for gas water heaters used in outdoor environments, when the external wind flow is large, the wind flow enters from the bottom of the shell, which can easily cause the flame to be extinguished. Therefore, some gas water heaters used outdoors have a small ventilation cross-sectional area of ​​the air inlet, and various wind shielding structures need to be installed. If the gas water heater with this structure is used indoors, it will lead to insufficient oxygen supply to the burner and incomplete combustion.

[0003] It can be seen that gas water heaters used indoors and outdoors need to be configured with different structures. Manufacturers need to produce different models according to different application scenarios, and users also need to choose different models according to their own usage environment, which leads to inconvenience in use and high cost. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a wind-resistant water heater, which can be compatible with indoor or outdoor application scenarios, is convenient and reliable to use, and has reduced production costs.

[0005] According to the first aspect of the utility model, a wind-resistant water heater comprises: a shell having a cavity therein; a combustion module arranged in the shell and located in the cavity, the combustion module comprising a heat exchange component and a burner, the heat exchange component being provided with a smoke exhaust port connected to the outside, the burner being used to be connected to a gas source and the combustion end of the burner being able to output flames, a heat collecting port being provided below the heat exchange component, the heat exchange component being covered above the combustion end of the burner through the heat collecting port and an air inlet interval connected to the cavity being provided between the inner side wall of the heat collecting port and the burner; wherein the shell is provided with a first air inlet connected to the cavity, a gap being provided between the inner wall of the shell and the outer side wall of the heat exchange component to form at least part of an air guide channel, the air guide channel being connected to the air inlet interval, and the first air inlet being located above the burner and connected to the air guide channel.

[0006] A wind-resistant water heater according to an embodiment of the utility model has at least the following beneficial effects:

[0007] The utility model is a wind-resistant water heater. When used outdoors, the wind flow is strong. The wind flow enters the cavity from the first air inlet. At this time, the wind flow needs to be transmitted downward along the wind guide channel. The wind flow is blocked by the wall surface of the heat exchange component and the inner wall of the shell. The strength of the wind flow will be attenuated to a certain extent, and then enters the air inlet interval to provide the burner with combustion output flame. Compared with the traditional air inlet arranged at the bottom of the shell, since the heat collecting port covers the top of the combustion end of the burner, the wind flow entering from the first air inlet is not easy to blow directly to the flame and cause the flame to be extinguished.

When the flame burns, oxygen will be consumed, and the heat will cause the exhaust gas to rise and be discharged from the smoke exhaust port. Negative pressure is formed in the area covered by the heat collecting port. The outside wind flow is affected by the negative pressure and will continue to enter from the first air inlet to supplement the air required for combustion for the combustion end of the burner.

[0029] like Figure 1-Figure 4As shown, according to the first aspect of the utility model, a wind-resistant water heater includes a shell 100 and a combustion module. The shell 100 is provided with a cavity 110. The combustion module is arranged in the shell 100 and is located in the cavity 110. The combustion module includes a heat exchange component and a burner 400. The heat exchange component is provided with a smoke exhaust port 210 connected to the outside. The burner 400 is used to be connected to a gas source and the combustion end of the burner 400 can output flames. A heat collection port 220 is provided below the heat exchange component. The heat exchange component is provided with a smoke exhaust port 210 connected to the outside. The burner 400 is used to be connected to a gas source and the combustion end of the burner 400 can output flames. 20 is covered above the combustion end of the burner 400 and there is an air inlet section 230 between the inner wall of the heat collecting port 220 and the burner 400 and connected to the cavity 110, wherein the shell 100 is provided with a first air inlet 120 connected to the cavity 110, and there is a gap between the inner wall of the shell 100 and the outer wall of the heat exchange component to form at least part of the air guide channel 140, and the air guide channel 140 is connected to the air inlet section 230, and the first air inlet 120 is located above the burner 400 and is connected to the air guide channel 140.

[0030] Generally speaking, the shell 100 can be in a rectangular or barrel shape, the combustion module is arranged in the shell 100, the burner 400 is connected to the gas source, the smoke exhaust port 210 extends from the top of the shell 100 to the outside, the heat exchange component can be made of plate materials such as metal or alloy, water can pass through the heat exchange component, the burner 400 heats the heat exchange component and thus transfers the heat to the water to heat the water, the burner 400 ignites the gas, and the exhaust gas generated by the reaction of the gas with oxygen in the air can be discharged from the smoke exhaust port 210, and the plate material of the heat exchange component can form a wall surface, thereby, the air guide channel 140 can be surrounded by the inner wall of the shell 100 and the outer wall of the heat exchange component.

[0031] In some embodiments of the present invention, Figure 2 , Figure 3 As shown, the heat exchange component includes a smoke exhaust hood 200 and a heat exchanger 300, the heat exchanger 300 is located in the smoke exhaust hood 200, the heat collection port 220 is arranged at the lower end of the smoke exhaust hood 200, the smoke exhaust hood 200 is covered above the combustion end of the burner 400 through the heat collection port 220, the combustion end of the burner 400 outputs flame to heat the heat exchanger 300, and the smoke exhaust port 210 is arranged above the smoke exhaust hood 200.

[0032] A water pipe is provided in the heat exchanger 300. The flame output by the burner 400 heats the heat exchanger 300, thereby heating the water flowing through the water pipe. The smoke exhaust hood 200 is made of plate materials such as metal or alloy. A combustion chamber is enclosed inside the smoke exhaust hood 200. The heat collecting port 220 covers the combustion end to prevent the wind flow from blowing out the flame, and the exhaust gas generated by the combustion can rise to the top and be discharged from the smoke exhaust port 210.

[0033] The utility model is wind-resistant and can be installed outdoors or indoors according to actual needs. When used outdoors, the wind flow is strong, and the wind flow enters the cavity 110 from the first air inlet 120. At this time, the wind flow needs to be transmitted downward along the wind guide channel 140. The wind flow is blocked by the wall surface of the heat exchange component and the inner wall of the shell 100, and the strength of the wind flow will be attenuated to a certain extent. Then, the wind flow passes through the air inlet interval 230 and is provided to the burner 400 to burn and output flames. Compared with the traditional air inlet set at the bottom of the shell 100, since the heat collecting port 220 covers the top of the combustion end of the burner 400, the wind entering from the first air inlet 120 It is not easy for the wind to blow directly towards the flame and cause the flame to go out. When used indoors, the combustion end of the burner 400 can still maintain a large ventilation cross-sectional area with the outside world through the air inlet section 230, the air guide channel and the first air inlet 120. The flame consumes oxygen when burning, and the heat causes the exhaust gas to rise and be discharged from the smoke exhaust port 210. Negative pressure is formed in the area covered by the heat collection port 220. The outside wind flow is affected by the negative pressure and will continue to enter from the first air inlet 120 to supplement the air required for combustion for the combustion end of the burner 400. This design can be compatible with indoor or outdoor application scenarios, is easy and reliable to use, and reduces production costs.

[0034] In order to prevent the top wind flow from pouring in from the smoke exhaust port 210, thereby affecting the burning of the flame, in some embodiments of the present invention, such as Figure 1 , Figure 2 As shown, a wind shield 500 is provided on the top of the shell 100 , a smoke exhaust cavity 510 is provided in the wind shield 500 , a ventilation port group connected to the smoke exhaust cavity 510 is provided between the wind shield 500 and the shell 100 , and the smoke exhaust port 210 is connected to the smoke exhaust cavity 510 .

[0035] The wind shield 500 provides a certain degree of shielding for the smoke exhaust port 210 , and external wind can enter from the vent group, and then carry the waste gas output from the smoke exhaust port 210 out from the vent group, thereby reducing wind intensity and preventing wind from entering from the smoke exhaust port 210 .

[0036] Specifically, the wind shield 500 can be a flat or convex arc-shaped top cover plate, and a plurality of support rods are provided on the bottom surface of the wind shield 500, and the bottom ends of the support rods are provided on the shell 100, so as to support the wind shield 500 above the smoke exhaust port 210, and the inner wall of the wind shield 500 and the top end surface of the shell 100 form a semi-closed smoke exhaust cavity 510, and the interval between the inner wall of the wind shield 500 and the top end surface of the shell 100 forms a ventilation port group.

[0037] In some embodiments of the present invention, Figure 2 , Figure 4 As shown, a partition plate 600 is disposed on the shell 100 or the heat exchange assembly, and the partition plate 600 is used to separate the receiving cavity 110 and the smoke exhaust cavity 510 .

[0038] The partition plate 600 separates the containing cavity 110 and the smoke exhaust cavity 510, so that the wind flows entering from the first air inlet 120 and the ventilation port group are isolated from each other, ensuring that the wind flow entering from the first air inlet 120 will not be too large to affect the normal combustion of the flame.

[0039] Specifically, the partition plate 600 is annular and is sleeved on the heat exchange assembly. The outer edge of the partition plate 600 is combined with the inner wall of the shell 100 to separate the containing cavity 110 and the smoke exhaust cavity 510 .

[0040] It should be noted that there may still be a partial gap or opening between the inner edge of the partition plate 600 and the outer wall of the heat exchange assembly or the outer edge of the partition plate 600 and the inner wall of the shell 100, which can still be considered as separating the cavity 110 and the smoke exhaust cavity 510.

[0041] In some embodiments of the present invention, Figure 1 , Figure 2 As shown, the vent group includes at least a first vent 520 and a second vent 530 , the first vent 520 and the second vent 530 are relatively arranged on both sides of the smoke exhaust cavity 510 , and the smoke exhaust port 210 is located between the first vent 520 and the second vent 530 .

[0042] Since the first vent 520 and the second vent 530 are relatively arranged on both sides of the smoke exhaust chamber 510, the wind can enter the smoke exhaust chamber 510 from the first vent 520, carry the exhaust gas discharged from the smoke exhaust port 210 and then blow out from the second vent 530, and the wind enters from the first vent 520 and then blows out from the second vent 530 directly opposite, where a negative pressure can be formed at the exhaust port, further guiding the exhaust gas generated by the flame combustion to be discharged.

[0043] In some embodiments of the present invention, Figure 2As shown, the outer wall of the smoke exhaust hood 200 and the inner wall of the housing 100 are spaced apart to form at least a portion of the air guide channel 140 , and the first air inlet 120 faces the outer wall of the smoke exhaust hood 200 .

[0044] The first air inlet 120 faces the outer wall of the smoke exhaust hood 200. When the wind flows into the cavity 110 from the first air inlet 120, the wind flows directly against the outer wall of the smoke exhaust hood 200, so that the intensity of the wind flows rapidly decays. Then the wind flows downward along the air guide channel and passes through the air inlet section 230, further preventing the wind flow from extinguishing the flame.

[0045] In some embodiments of the present invention, Figure 1 , 2 As shown, there are multiple first air inlets 120, and the multiple first air inlets 120 are arranged around the smoke exhaust hood 200. The multiple first air inlets 120 are arranged circumferentially around the smoke exhaust hood 200, so that in an environment with relatively small indoor wind flow, air from all directions enters into the cavity 110 from the first air inlets 120 around the smoke exhaust hood 200, thereby supplementing sufficient oxygen for the combustion of the burner 400.

[0046] In order to prevent the burner 400 from burning insufficiently due to the small air flow entering from the first air inlet 120 when installed indoors, thereby reducing the combustion efficiency and causing the generation of carbon monoxide, in some embodiments of the present invention, such as Figure 3 As shown, the housing 100 is provided with a second air inlet 130 communicating with the cavity 110 below the burner 400 , and a ventilation cross-sectional area of ​​the second air inlet 130 is smaller than a ventilation cross-sectional area of ​​the first air inlet 120 .

[0047] By setting a second air inlet 130, auxiliary air intake is provided to meet the air required by the burner 400. It should be noted that the second air inlet 130 here can be a microhole set on the shell 100 or a gap between the plates enclosing the shell 100. The ventilation cross-sectional area of ​​the second air inlet 130 is much smaller than the ventilation cross-sectional area of ​​the first air inlet 120. Therefore, when installed outdoors, wind flow will not enter at the second air inlet 130 and form a strong wind flow, which will affect the burning of the flame.

[0048] Specifically, the second air inlet 130 is arranged on the bottom surface of the shell 100. When installed outdoors, the wind flow usually hits the side of the shell 100. Compared with the second air inlet 130 arranged on the side of the shell 100, the wind flow intensity flowing through the second air inlet 130 arranged on the bottom surface of the shell 100 is lower. When installed indoors, the second air inlet 130 arranged on the bottom surface of the shell 100 can also meet the demand for air passing through.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
