DETAILED DESCRIPTION

[0027] ​​​​In the following description, numerous specific details are provided in order to provide a thorough understanding of the present application. One of ordinary skill in the art will realize, however, that the application can be practiced without one or more of the specific details, or with other methods, components, materials, and so on. In other instances, well-known structures have not been described in detail in order to avoid obscuring aspects of the present application.

[0028] In order to thoroughly understand the embodiments of the present application, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can have other embodiments.

[0029] The embodiments of the present application provide a gas water heater. Hereinafter, a gas water heater according to the embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0030] With reference to Figures 1 to 5 , the gas water heater 1 can include a housing 10, a burner 20 and a heat exchanger 30. The housing 10 can enclose a receiving cavity 40. The heat exchanger 30 and the burner 20 can be arranged in the receiving cavity 40 in an up-down manner. The housing 10 can have a front shell 110. The front side of the heat exchanger 30 and the front side of the burner 20 can jointly form a reference surface. An installation space 410 can be formed between the front shell 110 and the reference surface. A partition plate 50 can be arranged in the installation space 410. The projection of the burner 20 and the heat exchanger 30 towards the direction of the front shell 110 can fall into the partition plate 50.

[0031] The gas water heater 1 of the present application, by arranging the partition plate 50 in the installation space 410 formed between the front shell 110 and the reference surface, and the projection of the burner 20 and the heat exchanger 30 towards the direction of the front shell 110 falling into the partition plate 50, the heat radiated outward can be blocked by the partition plate 50, avoiding the problem of user's accidental touch scalding caused by the temperature of the front shell 110 being too high, at the same time, improving the thermal efficiency and reducing the noise generated during work.

[0032] It should be noted that the front shell 110 is located on the side of the housing 10 closer to the operator.

[0033] With reference to Figures 2 to 4The partition plate 50 can have a plate body 510. A gap 60 can be formed between the plate body 510 and the reference surface. The gap 60 can have a size L1, L1≥4mm. For example, the size L1 can be 4mm, 6mm, 9mm, etc. In this way, the gap 60 is formed between the partition plate 50 and the reference surface, which facilitates the air flow into the burner 20, on the one hand, ensures the combustion efficiency of the burner 20; on the other hand, the air entering from the outside can absorb part of the heat in the process of the burner 20, thereby further reducing the heat radiated to the front shell 110, and further reducing the temperature of the front shell 110.

[0034] With reference to Figures 3 to 5 The outer edge of the plate body 510 can extend in the direction of the burner 20 and the heat exchanger 30 to form a flange portion 511. In this way, not only is the heat in the gap 60 radiated outward from both sides of the partition plate 50 avoided, but the combustion efficiency is also ensured. The flange portion 511 and the plate body 510 form an integral structure, and the flange portion 511 can be formed by stamping process or by bending the plate body 510, as long as it is convenient to process the flange portion 511.

[0035] In some embodiments, the flange portion 511 can be provided on different positions of the outer edge of the plate body 510.

[0036] Exemplarily, the flange portion 511 can be provided on the outer edge of the plate body 510 located on the left and right sides of the burner 20 and the heat exchanger 30. At this time, the heat in the gap 60 is radiated outward from both sides of the partition plate 50 is avoided, and air can enter the gap 60 through the edges of the plate body 510 located on the upper and lower sides of the burner 20 and the heat exchanger 30, ensuring the combustion efficiency of the burner 20, further reducing the heat radiated to the front shell 110, and further reducing the temperature of the front shell 110.

[0037] Exemplarily, the flange portion 511 can be provided on the outer edge of the plate body 510 located on the left side, the right side and the upper side of the burner 20 and the heat exchanger 30.

[0038] Exemplarily, the flange portion 511 can be provided on the outer edge of the plate body 510 located on the left side, the right side and the lower side of the burner 20 and the heat exchanger 30.

[0039] Exemplarily, the flange portion 511 can be provided on the outer edge of the plate body 510 around the plate body 510, but an opening is provided on the outer edge located on the left and right sides of the heat exchanger 30.

[0040] Exemplarily, the flange portion 511 can be provided on the outer edge of the plate body 510 around the plate body 510, and an opening is provided on the flange portion 511 located on the left and right sides of the burner 20.

[0041] Again with reference to Figures 3 to 5The flange portion 511 can have a size L2, L2≥L1. When the size L1 and the size L2 have this relationship, not only the strength of the partition plate 50 can be increased, but also heat radiation from both sides of the partition plate 50 outward is further avoided. In some embodiments, L2=L1, at this time, not only heat radiation from both sides of the partition plate 50 outward is avoided, but also material is saved.

[0042] Again, referring to Figures 3 to 5 , L2≥5mm. For example, the size L2 can be 5mm, 6mm, 7mm, etc. L2 is in this range, further increasing the strength of the partition plate 50, and avoiding heat radiation from both sides of the partition plate 50 outward.

[0043] Again, referring to Figures 3 to 5 , the flange portion 511 can extend a connecting portion 512 thereon. The connecting portion 512 can be provided with a connecting hole 5121 for a fastener to pass through. In this way, the partition plate 50 is convenient to install, and the structure is simple. The connecting portion 512 can be formed in an integral structure with the flange portion 511 by integral molding, welding, etc., which is convenient for processing the connecting portion 512.

[0044] Specifically, the flange portion 511 can be provided with a plurality of connecting portions 512. The plurality of connecting portions 512 can be arranged at intervals on the flange portion 511. In this way, the firmness of the connection is effectively enhanced. In some embodiments, the outer edge of the plate body 510 can also extend a connecting portion 512 thereon. Understandably, in the direction perpendicular to the plate body 510, the size of the connecting portion 512 extending from the outer edge of the plate body 510 is not less than the size of the connecting portion 512 extending from the flange portion 511 plus the size of the flange portion 511.

[0045] Referring to Figures 2 to 5 , the plate body 510 can have a first plate portion 513 and a second plate portion 514 connected below the first plate portion 513. The projection of the heat exchanger 30 in the direction of the front shell 110 can fall into the first plate portion 513. The projection of the burner 20 in the direction of the front shell 110 can fall into the second plate portion 514. In this way, the first plate portion 513 and the second plate portion 514 can respectively shield the heat exchanger 30 and the burner 20 from the front, to adapt to different use scenarios, effectively avoiding the problem of user mis-touching and being scalded by the front shell 110 being too hot.

[0046] Understandably, the first plate part 513 and the second plate part 514 can be a split structure. The first plate part 513 and the second plate part 514 can shield the heat exchanger 30 and the burner 20 respectively. The user can select to install the first plate part 513 or the second plate part 514 alone or select to install the first plate part 513 and the second plate part 514 simultaneously according to the use scenario, improving the user experience. Of course, the first plate part 513 and the second plate part 514 can be formed into an integrated structure through a bending process or a stamping process.

[0047] Again in combination with reference to Figures 2 to 5 , the second plate part 514 can be farther away from the front shell 110 than the first plate part 513. The first plate part 513 and the second plate part 514 can be connected through the first bending part 515. In this way, not only can the heat exchanger 30 and the burner 20 be adapted, but also the structural strength of the partition plate 50 can be improved.

[0048] In some embodiments, a third plate part 516 can be provided above the first plate part 513. The projection of the upper part area of the heat exchanger 30 in the direction in which the front shell 110 is located can fall within the third plate part 516. In this way, the third plate part 516 can shield the upper part area of the heat exchanger 30, avoiding the problem that heat is radiated from the upper part area of the heat exchanger 30 to the front shell 110, causing the user to be scalded by mistake due to the high temperature of the front shell 110. The third plate part 516 can form a split structure with the first plate part 513. When the working power of the gas water heater 1 is too high and a large amount of heat is generated, the user can install the third plate part 516 to block the heat. When the working power of the gas water heater 1 is not high and a small amount of heat is generated, the user can disassemble the third plate part 516.

[0049] Specifically, the third plate part 516 can be farther away from the front shell 110 than the first plate part 513. The third plate part 516 can be connected to the end of the first plate part 513 away from the second plate part 514 through the second bending part 517. In this way, not only can the heat exchanger 30 and the upper part area of the heat exchanger 30 be adapted, but also the structural strength of the partition plate 50 can be improved.

[0050] Reference Figure 2 , except for the edge connected to the first plate part 513, the first distance D1 between the remaining edges of the second plate part 514 and the edges of the burner 20 can be D1≥1.5mm. For example, the first distance D1 can be 1.5mm, 2mm, 4mm, etc. The first distance D1 in this range effectively ensures that the second plate part 514 can completely shield the burner 20 from the front.

[0051] Again in combination with reference to Figure 2The second distance D2 between the remaining edges of the first plate part 513 and the edges of the heat exchanger 30, except the edge connected with the second plate part 514, can be 1.5mm or more. For example, the second distance D2 can be 1.5mm, 2mm, 4mm, etc. The second distance D2 in this range effectively ensures that the first plate part 513 can completely shield the heat exchanger 30 from the front.

[0052] With reference to Figure 2 and Figure 5 The second plate part 514 can be provided with a fire observation hole 5141. In this way, the user can observe the flame of the burner 20, and the fire observation hole 5141 can also provide the air required for combustion of the burner 20, thereby ensuring the combustion efficiency of the burner 20. The fire observation hole 5141 can be configured as a row of small holes, which facilitates observation by the user while avoiding the problem of excessive heat loss due to the large size of the fire observation hole 5141. It should be understood that the front shell 110 can be provided with a transparent structure at a position corresponding to the fire observation hole 5141, so that the user can observe the flame of the burner 20 through the front shell 110.

[0053] In an embodiment not shown, the front shell 110 can also be provided with an observation hole at a position corresponding to the fire observation hole 5141, so that the user can observe the flame of the burner 20 through the observation hole in the front shell 110. Further, the observation hole can be provided with a transparent baffle, which can protect the user and will not block the user's view.
