DETAILED DESCRIPTION

[0044] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0045] The embodiment of the present invention provides a mounting assembly 100 for an electric control panel 300 of a water heater 1, such as Figure 1-Figure 8As shown, the mounting assembly 100 is applied to the water heater 1 described below, and the mounting assembly 100 is used to mount the electric control board 300 inside the water heater 1 and located at the air inlet of the fan 200. The mounting assembly 100 can mount the electric control board 300 at the air inlet of the fan 200, and take away the heat of the electric control board 300 through air convection to dissipate heat and cool the electric control board 300. This heat dissipation method can effectively dissipate heat using the air intake of the fan 200, and has low cost.

[0046] The embodiment of the present invention provides a water heater 1, such as Figure 1-Figure 4 As shown, the water heater 1 includes a fan 200, an electric control board 300 and a mounting assembly 100. The fan 200 is installed inside the water heater 1 and is used to inhale air into the inside of the water heater 1; the electric control board 300 is installed inside the water heater 1 through the mounting assembly 100 and is located at the air inlet of the fan 200. By installing the electric control board 300 at the air inlet of the fan 200, the heat of the electric control board 300 is taken away by air convection to dissipate heat and cool the electric control board 300. This heat dissipation method can effectively dissipate heat using the incoming air of the fan 200 and is low in cost. In addition, being located at the air inlet can reduce the space on the left and right sides, and the width of the whole machine is smaller.

[0047] Specifically, the electric control board 300 may be a control board of the water heater 1, and the fan 200 may be an air inlet fan 200 of the water heater 1 in the prior art, and the fan 200 may draw air into the water heater 1 for combustion. The fan 200 includes an air inlet and an air outlet, and the air outlet may be connected to the combustion chamber 400 of the water heater 1, and the air enters the fan 200 through the air inlet and flows from the air outlet to the combustion chamber 400.

[0048] like Figure 1 and Figure 2 As shown, the fan 200 is installed at the bottom of the water heater 1, and the electric control board 300 is installed at the bottom of the water heater 1 through the mounting assembly 100; and in the thickness direction D of the water heater 1, the fan 200 and the electric control board 300 are arranged opposite to each other. The fan 200 can generate stronger air intake, thereby forming a stronger convection effect, thereby improving the heat dissipation effect. Specifically, the water heater 1 is a balanced water heater 1, and the air inlet channel 10 and the air outlet channel 20 of the water heater 1 are both located at the top of the water heater 1. The air inlet channel 10 is arranged around the air outlet channel 20, and the fan 200 is installed at the bottom of the water heater 1. The air enters from the air inlet channel 10 at the top and flows to the air inlet of the fan 200 located at the bottom. The electric control board 300 is arranged in front of the air inlet and is located on the air inlet flow path. In this arrangement, the air flow path is longer, and the electric control board 300 can also be located on the air flow path, thereby forming a stronger air convection and improving the heat dissipation effect.

[0049] like Figure 1 and Figure 2 As shown, the water heater 1 includes a housing 30, a combustion chamber 400 is provided above the fan 200, the upper end of the mounting assembly 100 is connected to the housing 410 of the combustion chamber 400, and the lower end of the mounting assembly 100 is connected to the bottom of the housing 30. The mounting assembly 100 and the electric control board 300 mounted thereon can be reliably installed inside the combustion chamber 400. Specifically, in the balanced water heater 1, the housing 30 is usually a substantially closed structure, and the space inside it is used to install the combustion chamber 400, the fan 200 and other functional components of the water heater 1, and the above-mentioned air inlet channel 10 and air outlet channel 20 are provided on the top plate of the housing 30. The mounting assembly 100 can be connected with the housing 30 of the water heater 1 by using the housing 410 of the combustion chamber 400.

[0050] In the width direction W of the water heater 1, at least one of the two opposite sides of the mounting assembly 100 is provided with a main air inlet channel M; and / or, in the thickness direction D of the water heater 1, the mounting assembly 100 is provided with an auxiliary air inlet channel F. The main air inlet channel M and / or the auxiliary air inlet channel F are provided on the mounting assembly 100, so that air can enter the mounting assembly 100 to dissipate heat from the electric control board 300, thereby improving the heat dissipation effect. In specific implementation, Figure 5 and Figure 6 As shown, the main air inlet channel M and the auxiliary air inlet channel F can be formed by setting an opening 101, a hole 102 on the wall of the installation component 100, etc. The opening 101 and the hole 102 can be a through hole set on the wall, or an open part generated by the contour on the wall.

[0052] The wall of the mounting assembly 100 is also provided with a harness hole 1131, and in the height direction H of the water heater 1, the position of the harness hole 1131 is staggered from the fan 200. By providing the harness hole 1131, the position where the harness is led out through the harness hole 1131 can be limited, so that the harness is prevented from being drawn into the air inlet and blocking the fan 200, thereby preventing the fan 200 from operating abnormally.

[0054] like Figure 5 and Figure 6 As shown, the first installation shell 110 is connected to the second installation shell 120 to form a receiving space, and the electric control board 300 is arranged in the receiving space. Thus, the electric control board 300 is installed and effectively protected. The side wall of the first installation shell 110 and the side wall of the second installation shell 120 are connected by a buckle structure 130. Specifically, in the width direction W of the water heater 1, the two side walls of the first installation shell 110 and the two side walls of the second installation shell 120 are connected by the buckle structure 130.

[0055] The first installation shell 110 and the second installation shell 120 both include a panel and a side wall. Figure 5-Figure 8As shown, the first mounting shell 110 has a first panel 111, a first left side wall 112, a first right side wall 113, a first upper side wall 114 and a first lower side wall 115, and the first left side wall 112, the first right side wall 113, the first upper side wall 114 and the first lower side wall 115 are respectively connected to the four edges of the first panel 111. The second mounting shell 120 has a second panel 121, a second left side wall 122 and a second right side wall 123, and the second left side wall 122 and the second right side wall 123 are respectively connected to the left and right edges of the second panel 121.

[0056] The first left side wall 112 and the second left side wall 122 are connected by a buckle structure 130. Figure 6 As shown, the second left side wall 122 and the second left side wall 122 are provided with two buckle structures 130, and the two buckle structures 130 are arranged at intervals in the height direction H of the water heater 1. The first right side wall 113 and the second right side wall 123 are connected by the buckle structure 130, as shown in FIG. Figure 5 As shown, the upper portions of the first right side wall 113 and the second right side wall 123 are provided with a snap-fit ​​structure 130 .

[0057] In addition, if Figure 7 As shown, the first panel 111 is provided with a fixing hole 1111 for installing the electric control board 300, and support feet 1112 are provided between the first panel 111 and each side wall, and the electric control board 300 is embedded in the space formed by these support feet 1112. The fixing hole 1111 and the support feet 1112 facilitate the installation and fixation of the electric control board 300.

[0058] Furthermore, in a specific implementation, there are many ways for the first mounting shell 110 and the second mounting shell 120 to form the main air inlet flow channel M and / or the auxiliary air inlet flow channel F. Figure 5-Figure 8 Some specific implementations are provided.

[0059] The side wall of the first installation shell 110 and / or the side wall of the second installation shell 120 is provided with an opening 101, so that the side wall of the first installation shell 110 and the side wall of the second installation shell 120 are connected to form a main air inlet flow channel M. Preferably, both side walls of the first installation shell 110 and the second installation shell 120 in the width direction W of the water heater 1 are provided with an opening 101.

[0060] like Figure 6 and Figure 8As shown, the portion other than the snap-fit ​​structure 130 provided on the first left side wall 112 and the second left side wall 122 can form a main air inlet channel M. Specifically, an opening 101 in the form of a through hole is provided above the first left side wall 112, and an opening 101 in the form of an open outline is provided above the second left side wall 122. When the first left side wall 112 and the second left side wall 122 are connected, the two openings 101 overlap on the left side of the installation component 100 to form the main air inlet channel M.

[0061] like Figure 5 and Figure 7 As shown, the first right side wall 113 is provided with an opening 101 in the form of a vertically extending through hole. In addition, the edge of the first right side wall 113 near the second right side wall 123 is also provided with an opening 101 in the form of an open outline. The opening 101 preferably extends downward from the top of the first right side wall 113. Specifically, the opening 101 is formed in a manner of reducing the wall length of the first right side wall 113. The second right side wall 123 is provided with an opening 101 in the form of an open outline in the portion other than the snap-fit ​​structure 130, so that when the first right side wall 113 and the second right side wall 123 are connected, a main air inlet flow channel M with a larger flow area is formed on the right side of the installation assembly 100.

[0062] Preferably, an opening 101 is further provided at the top of the mounting assembly 100, and the opening 101 can be used as a reserved air intake space.

After the pipe 500 of the water outlet pipe extends horizontally, it extends vertically. The second panel 121 is a baffle 1211 at a position corresponding to the pipe 500 of the water outlet pipe, so that the second panel 121 forms an opening 101 in the form of an open profile at the edge close to the inside of the water heater 1. The opening 101 can correspond to the high temperature heating area of ​​the electric control board 300, thereby further improving the heat dissipation effect. And, as Figure 7 As shown, a flange 1212 is further provided on the upper portion of the second panel 121 , and the flange 1212 can be used as a baffle 1211 , thereby improving the protection effect of the electric control board 300 .
