Description

Technical Field

[0001] The utility model belongs to the technical field of water heaters, and particularly relates to a gas water heater. Background Art

[0002] like Figure 1 As shown, when the gas water heater is working, it is affected by the internal negative pressure and will take in air from the air inlet on the upper part of the shell 1 for use by the combustion 21. Due to the obstruction of the fan 23, the heat exchanger 22 and the burner 21, after the air enters the shell 1, most of the air will flow within the range of area B, and the air diffuses downward, passing through the fan, the heat exchanger and the wall of the burner facing area B in turn, and finally enters the interior of the burner 21 through the bottom end of the burner 21. In this way, the air intake in area A will be very small; since the air intake in area A is very small, it cannot take away the heat from the surface of the heat exchanger and the wall of the burner facing area A, causing heat accumulation in area A to form high temperature, and area A is close to the front of the shell, and is easily discolored due to high temperature, which reduces the quality of the gas water heater. Electronic components such as display panels are also placed on the front of the shell. The life of electronic components is easily shortened at high temperatures, which reduces the quality of the gas water heater. Utility Model Content

[0003] In order to overcome the above technical defects, the utility model discloses a gas water heater, which aims to solve the problem that the high temperature in zone A reduces the quality of the gas water heater.

[0023] In order to better illustrate the present invention, the present invention is further described in detail below with reference to the accompanying drawings.

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0025] In order to better illustrate the present invention, the present invention is further described in detail below with reference to the accompanying drawings.

[0026] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present application. The singular forms "a," "the," and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0027] Combine Figures 2 to 4 As shown, the utility model discloses a gas water heater, comprising:

[0028] A housing 1, wherein an air inlet is provided on the rear side of the housing 1; electronic components are mounted on the front side of the housing 1;

[0029] A main functional component is installed in the housing 1. The main functional component includes a burner 21, a heat exchanger 22, and a fan 23 arranged in the housing 1 from bottom to top. A first spacing section 11 is defined between the front side of the main functional component and the housing 1, and a second spacing section 12 is defined between the rear side of the main functional component and the housing 1.

[0030] The guide member 3 is installed in the shell 1, and the guide member 3 has an air accommodating cavity 31, a first air outlet portion 32 and a second air outlet portion 33. The air accommodating cavity 31 is connected to the air inlet, and the first air outlet portion 32 and the second air outlet portion 33 are both connected to the air accommodating cavity 31. The first air outlet portion 32 faces the first interval section 11, and the second air outlet portion 33 faces the second interval section 12.

[0031] Compared with the prior art, the utility model discloses a gas water heater, in which outside air enters the air cavity 31 of the guide member 3 from the air inlet on the rear side of the shell 1, and is then discharged through the second air outlet portion 33 and the first air outlet portion 32, thereby controlling the air flow through the first interval 11 and the second interval 12, allowing more air to enter the existing first interval 11, effectively reducing the temperature of the first interval 11, reducing the temperature difference between the first interval 11 and the second interval 12, avoiding the discoloration of the shell surface on the front side of the shell 1 due to high temperature, and reducing the life of electronic components installed on the front side of the shell 1 due to high temperature, thereby effectively improving the product quality of the gas water heater.

[0032] This structure also reduces the buildup of condensation in the heat exchanger pipes within the second compartment. By diverting the air flow, the air flow in the second compartment decreases, resulting in a higher temperature than before. This prevents the large amount of air carrying away heat from the second compartment, creating a low-temperature zone. This can lead to condensation in the heat exchanger pipes when the gas water heater is running at low heat.

[0033] It should be noted that the first interval 11 corresponds to Figure 1 In area A, the second interval 12 corresponds to Figure 1 Area B in.

[0034] In one embodiment, the guide member 3 is located in the middle of the housing 1, so that air can diffuse rapidly downward from the middle position, allowing the air to flow through the outer walls of the heat exchanger and the burner, removing heat. Preferably, the height positions of the first air outlet and the second air outlet are adapted to the height position of the heat exchanger, allowing the air to enter the housing through the first air outlet and the second air outlet, quickly contact the wall of the heat exchanger, remove heat from the heat exchanger wall, and then diffuse downward to contact the burner wall, remove heat from the burner wall, and then enter the burner through the bottom of the burner to supply oxygen.

[0035] In one embodiment, since the distance between the first air outlet 32 ​​and the air inlet is greater than the distance between the second air outlet 33 and the air inlet, after the air enters the interior of the guide member 3 through the air inlet, the air will first pass through the second air outlet 33 to enter the second interval 12, and then pass through the first air outlet 32 ​​to enter the first interval 11, that is, the speed and flow of air entering the first interval 11 are smaller than those of the second interval 12; therefore, in order to speed up the speed of air entering the first interval 11 and increase the air flow rate entering the first interval 11, the utility model sets the opening area of ​​the first air outlet 32 ​​to be larger than the opening area of ​​the second air outlet 33, so that the air can flow more easily to the first air outlet 32, and then flow into the first interval 11.

[0036] In one embodiment, the first air outlet portion 32 is composed of a plurality of first air outlets, which has a simple structure. Furthermore, providing a plurality of first air outlets on the air guide 3 can better ensure the structural strength of the air guide 3 compared to providing a single large air outlet. Preferably, the plurality of first air outlets are arranged in a lattice pattern.

[0037] In one embodiment, the second air outlet portion 33 is composed of a plurality of second air outlets, which has a simple structure. Furthermore, providing a plurality of second air outlets on the air guide 3 can better ensure the structural strength of the air guide 3 compared to providing a single large air outlet. Preferably, the plurality of second air outlets are arranged in a lattice pattern.

[0038] It should be noted that the first air outlet portion 32 and the second air outlet portion 33 may also be composed of one opening.

[0039] In one embodiment, the guide member 3 also has a movable baffle 34, which is used to change the air outlet area of ​​the first air outlet portion 32 and the second air outlet portion 33 to increase the versatility of the guide member 3. In this way, the same guide member 3 can be used to meet the use of gas water heaters of various specifications. According to the gas water heaters of various specifications, the position of the baffle 34 is adjusted, and then the area of ​​the opening of the first air outlet portion 32 and the second air outlet portion 33 covered by the baffle 34 is adjusted.

[0040] Furthermore, the baffle 34 includes a first baffle 34 and a second baffle 34. The first baffle 34 is used to change the air outlet area of ​​the first air outlet portion 32, and the second baffle 34 is used to change the air outlet area of ​​the second air outlet portion 33. Two baffles 34 are used to respectively change the air outlet areas of the first air outlet portion 32 and the second air outlet portion 33, so that the first air outlet portion 32 and the second air outlet portion 33 are relatively independent, and the air outlet area is easy to adjust.

[0041] The guide member 3 is provided with a guide rail 35 to guide the movement of the first and second baffles 34. The guide rail 35 can be positioned vertically or horizontally. When the guide rail 35 is positioned vertically, the first and second baffles 34 move vertically; when the guide rail 35 is positioned horizontally, the first and second baffles 34 move horizontally. Because the vertical space within the housing 1 is ample, and given the limited space along the thickness of the housing 1, the guide rail 35 in this embodiment 2 is positioned vertically to avoid interference between the two baffles 34.

[0042] Preferably, a strip hole for a fastener to pass through is designed on the baffle 34. When the baffle 34 is moved to a desired position, the fastener is passed through the strip hole and then threadedly connected to the guide member 3 to fix the baffle 34.

[0043] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and any modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience of description only and do not constitute any limitation to the present invention.
