Description

Technical Field

[0001] The utility model relates to the technical field of electronic control boxes, and particularly relates to an electronic control box structure for preventing condensed water and a gas-fired heating and hot water boiler thereof. Background Art

[0002] A gas-fired heating and hot water boiler, also simply referred to as a wall-mounted boiler, is mainly used for winter heating and domestic hot water. With the promotion of the national coal-to-gas project, gas-fired heating and hot water boilers have been widely used and popularized. A gas-fired heating and hot water boiler mainly consists of systems such as control, combustion, and heat exchange. It uses natural gas as fuel, and transfers the heat generated by combustion to the circulating water of the system through the heat exchange system to provide domestic hot water and heating heat for users.

[0003] The main control board of a gas-fired heating and hot water boiler is generally installed in an electronic control box assembly. Most of the electronic control box assemblies of gas-fired heating and hot water boilers on the market do not have a design for preventing condensed water or water vapor. The installation of a hot water boiler requires a gas supply. Most users install it in the kitchen and nearby locations. And the hot water boiler is mainly used in cold regions. In the north, the cooking habit is to steam food, so a large amount of water vapor is easily generated in the kitchen. When the water vapor in the indoor air meets the relatively low-temperature sheet metal shell of the hot water boiler, it will condense to form condensed water and gather into water droplets. The water droplets will flow along the shell wall and seep into the fastening gap between the front and rear covers of the electronic control box, resulting in the main board being burned out and causing unnecessary losses. On the other hand, when the hot air in the room meets the cold shell, it will also condense, and it is also easy to form water droplets on the shell wall of the hot water boiler and drip into the electronic control box and seep into the installation gap, resulting in the main board being short-circuited and burned out. Therefore, it is necessary to make a structure for preventing condensed water in the electronic control box assembly to reduce the risk of condensed water gathering and dripping onto the main board. Content of the Utility Model

Specific embodiments

[0033] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following specifically describes the embodiments of the present utility model in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0034] In the description of the present utility model, it should be understood that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0035] In the description of the present utility model, it should be understood that when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be intermediate elements present simultaneously. In contrast, when an element is referred to as being "directly" connected to another element, there are no intermediate elements.

[0036] Please refer to Figures 1 - 12 , which is a structure of an electronic control box for preventing condensation water in a preferred embodiment of the present utility model. It is used to be installed on devices such as a gas-fired heating and hot water boiler and a water heater, and is used to prevent condensation water and water vapor from entering the electronic control box to avoid short-circuit phenomena of the main control board 30. Specifically, the electronic control box structure includes a front cover 10, a rear cover 20, a main control board 30 and a display board 40 installed in the front cover 10 and the rear cover 20.

[0037] The front cover 10 is arranged at the front of the electronic control box, and the rear cover 20 is arranged at the rear of the electronic control box. The front cover 10 and the rear cover 20 are combined to form an inner cavity for installing the main control board 30 and the display board 40.

[0038] Such as Figures 6 - 7In [the device], in terms of the top part, a water baffle strip 11 in an inverted L shape is provided at the top of the front cover 10, and a long strip-shaped protrusion 21 is provided at the top of the rear cover 20. The protrusion 21 cooperates with the water baffle strip 11 to form a top water-proof structure. On the one hand, it raises the fitting surface gap between the two, and on the other hand, it changes the flat gap into a side gap, playing a role in changing the structure of the fitting surface gap. Moreover, the inverted L-shaped water baffle strip 11 can cover the vertically dripping water droplets from entering the gap, preventing the condensed water droplets from dripping and accumulating and seeping into the fitting surface gap of the electric control box installation, thereby preventing the water droplets formed by the accumulation of condensed water or water vapor on the outer shell wall from dripping onto the main board, resulting in the risk of burning out the main board. It also plays a role in blocking the water droplets on both sides of the top water-proof structure and guiding the water droplets to drain out of the electric control box.

[0039] As Figures 10 - 11 In [the device], in terms of the installation surface, a peripheral groove 12 is provided on the installation surface of the front cover 10, and a sealing flange 22 is provided on the installation surface of the rear cover 20. During installation, the sealing flange 22 is embedded in the peripheral groove 12 to form a sealed structure on the installation surface, improving the sealing effect of the connection surface between the front cover 10 and the rear cover 20 and preventing water vapor or dripping water droplets from entering the main control board 30 inside the electric control box through the gap. The combination of the sealed structure on the installation surface and the top water-proof structure achieves a comprehensive anti-condensation effect on the electric control box.

[0040] In this embodiment, as Figures 4 - 6 、 Figure 8 shown, a hook 13 is provided on the side of the front cover 10, and a buckle 23 is provided on the side of the rear cover 20. During assembly, the buckle 23 is buckled on the hook 13 to fix the structure of the front cover 10 and the rear cover 20, reducing screw assembly and improving assembly efficiency. In some other embodiments, a plurality of fixing pillars 14 are further provided inside the front cover 10, and a plurality of screw holes are provided on the rear cover 20. Each fixing pillar 14 is correspondingly arranged with each screw hole, facilitating the fixation of the fixing pillar 14 of the front cover 10 and the screw hole of the rear cover 20 by screws in case the buckle 23 or the hook 13 is damaged and fails.

[0041] As Figure 3 shown, a fixing ear 24 is further provided on the top of the rear cover 20. A fixing hole is provided on the fixing ear 24. Through the fixing hole and accessories such as bolts, the electric control box is fixed on the water heater. A drain hole 240 is provided at the bottom of the fixing ear 24, and the drain hole 240 is axially penetrated, such as penetrating through the fixing ear 24 from front to back, enabling the water droplets dripping in front of and behind the fixing ear 24 to be easily drained out, reducing the accumulation of water droplets on the electric control box. In another embodiment, the fixing ear 24 further includes a receiving block, and the receiving block is fixed on the rear cover 20 by welding or other means and cooperates with the structure of the fixing ear 24 to have a large bearing capacity, capable of supporting the electric control box fixed on the water heater.

[0042] As Figure 2 、 Figure 10 、Figure 12 As shown, a flipping part is provided on the front cover 10, and flipping shafts 15 for movably connecting with a water heater are provided on opposite sides of the flipping part. For example, Figure 2 is the structure of the electric control box before flipping. For example, Figure 12 is the structure of the electric control box after flipping. It flips outwards from the water heater, which is convenient for subsequent disassembly of accessories such as the rear cover 20 and the main display board 40.

[0043] For example, Figure 4 and Figure 10 As shown, a plurality of first clamping parts 16, second clamping parts 17, first mounting posts 18 and second mounting posts 19 are further provided inside the front cover 10. The first clamping part 16 cooperates with the second clamping part 17 and the first mounting post 18 to fix the display board 40, and the second mounting posts 19 are evenly distributed to fix the main control board 30. Among them, the height of the second mounting post 19 is greater than the height of the first mounting post 18 / the first clamping part 16 / the second clamping part 17, so that after the main control board 30 and the display board 40 are assembled, there is a heat dissipation gap between the main control board 30 and the display board 40.

[0044] Another example is Figure 5 As shown, a display window and key holes are provided on the front cover 10. A display lens is installed on the display window, and a control key is installed on the key holes. Both are positioned by the pillars of the front cover 10 of the electric control box and the display glass and the key are fixed to the front cover 10 of the electric control box by melting the pillars. In some other embodiments, a knob hole is provided on the front cover 10, and a knob is installed on the knob hole to cooperate with some controls on the display board 40.

[0045] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0046] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
