Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to a plastic water tank. Background Technology
[0002] With the development of automobiles, in order to reduce vehicle weight, some vehicles have combined the front cabin drainage channel and air conditioning intake duct into a single plastic drainage channel. This requires that the plastic drainage channel have a drainage structure to prevent liquid from accumulating inside.
[0003] When the vehicle's air conditioning is turned on, hot air will enter the plastic drainage channel through the drainage holes, resulting in high air intake temperature for the air conditioning system, which affects the air conditioning's cooling efficiency and increases the vehicle's energy consumption. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide a plastic drainage channel for allowing hot air to enter the plastic drainage channel from the drainage hole, thereby improving the air conditioning cooling efficiency and reducing vehicle energy consumption.
[0005] A plastic water tank includes a tank body and a valve plate. The tank body has a liquid collection groove and multiple drain holes. The drain holes are located at the lowest position of the liquid collection groove along its height direction. The valve plate is installed in the drain holes and has a deformation degree of freedom that allows it to deform away from the drain holes. The valve plate includes a sealed state that seals the drain holes and a drain state that is separated from the drain holes. When the valve plate is in the drain state, liquid is discharged out of the tank body through the drain holes.
[0006] Furthermore, along the height direction of the liquid collection groove, the valve plate is located at the bottom of the water tank body.
[0007] Furthermore, a mounting bracket is formed inside the drain hole, and the valve plate is mounted inside the drain hole through the mounting bracket.
[0008] Furthermore, along the height direction of the liquid collection groove, at least one limiting ring is formed at the bottom of the water tank body, the limiting ring corresponds one-to-one with the drain hole, and the drain hole is located inside the limiting ring.
[0009] Furthermore, the inner diameter of the limiting ring is greater than or equal to the diameter of the drain hole.
[0010] Furthermore, the outer edge of the valve plate is located outside the largest outer edge of the drain hole.
[0011] Furthermore, the valve disc includes a valve disc body, and along the height direction of the liquid collecting groove, the thickness of the valve disc body decreases from the edge of the valve disc to the center of the valve disc body.
[0012] Furthermore, the valve plate also includes a connecting post, which is located in the middle of the valve plate body.
[0013] Furthermore, along the height direction of the liquid collection groove, a guide pipe is also formed at the bottom of the water tank body; multiple drainage holes are located inside the guide pipe.
[0014] Furthermore, the liquid collecting groove includes a drainage surface and multiple guide surfaces, with the multiple guide surfaces respectively connected to the drainage surface; along the height direction of the liquid collecting groove, the drainage surface is connected to the lowest position of the guide surfaces.
[0015] By installing a valve plate inside the drain hole, the valve plate deforms when drainage is needed to facilitate the discharge of liquid from the plastic drainage channel. When the air conditioner is running, the valve plate seals the drain hole to prevent hot air from entering the plastic drainage channel, thereby improving the air conditioning cooling efficiency and reducing vehicle energy consumption.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0023] like Figure 1 and Figure 2As shown, as one implementation, this application provides a plastic water tank, including a water tank body 1 and a top cover 3. The top cover 3 is installed on the water tank body 1 to form a cavity 4 between the top cover 3 and the water tank body 1. Air and rainwater enter the plastic water tank through an opening on one side of the cavity 4.
[0024] The main body 1 of the water tank has a liquid collection groove 1-1 and multiple liquid discharge holes 1-2. Along the height direction of the liquid collection groove 1-1, the liquid discharge holes 1-2 are located at the lowest position of the liquid collection groove 1-1. The liquid entering the cavity 4 is stored in the liquid collection groove 1-1 and then discharged from the outside of the main body 1 of the water tank through the liquid discharge holes 1-2, thereby realizing the discharge of liquid to the outside of the cavity 4.
[0025] As one implementation, the plastic water tank also includes a valve plate 2, which is installed on the drain hole 1-2 and has a deformation degree of freedom that deforms away from the drain hole 1-2.
[0026] During the use of the plastic water tank, the valve plate 2 has a degree of freedom of deformation that is opposite to the drain hole 1-2, so the valve plate 2 includes a sealing state and a draining state.
[0027] When valve plate 2 is in a sealed state, valve plate 2 seals the drain hole 1-2 to prevent hot air from entering the water tank body 1 through the drain hole 1-2.
[0028] When the valve plate 2 is in the draining state, the valve plate 2 deforms away from the drain hole 1-2, causing the valve plate 2 to separate from the drain hole 1-2 at least partially, thereby causing the drain hole 1-2 to open at least partially, so that the liquid in the liquid collection groove 1-1 can be discharged to the outside of the plastic water tank.
[0029] Under normal conditions, valve plate 2 is in a sealed state.
[0030] When the vehicle's air conditioning is turned on, the airflow velocity in cavity 4 increases, causing the air pressure in cavity 4 to be lower than atmospheric pressure. Under the action of atmospheric pressure, valve plate 2 further abuts against drain hole 1-2, thereby sealing drain hole 1-2.
[0031] When liquid accumulates in the liquid collection groove 1-1, under the action of the liquid's gravity, the valve plate 2 deforms away from the drain hole 1-2, causing the drain hole 1-2 to open at least partially, thereby allowing the liquid to be discharged outside the plastic water tank.
[0032] It should be noted that when the vehicle's air conditioning is turned on and liquid accumulates in the liquid collection groove 1-1, the valve plate 2 will deform away from the drain hole 1-2 under the action of the liquid's gravity, thereby discharging the liquid out of the plastic drain channel.
[0033] To facilitate a clearer description of the technical solution of this application, the following definitions are provided: Figure 1The upward and downward directions are shown. The direction along the height of the liquid collection groove 1-1 refers to... Figure 1 The up and down directions in the middle.
[0034] like Figure 2 and Figure 3 As shown, in one implementation, along the height direction of the liquid collection groove 1-1, the valve plate 2 is located at the bottom of the water tank body 1, so that the valve plate 2 can deform in the direction away from the drain hole 1-2, so that the drain hole 1-2 is at least partially opened.
[0035] As one implementation method, a mounting bracket 1-3 is formed inside the drain hole 1-2, and the valve plate 2 is installed inside the drain hole 1-2 through the mounting bracket 1-3, thereby improving the installation convenience of the valve plate 2.
[0036] Specifically, along the height direction of the liquid collection groove 1-1, the mounting bracket 1-3 is located above the valve plate 2 so that the valve plate 2 can deform downward under the gravity of the liquid.
[0037] Meanwhile, by setting up the mounting brackets 1-3, it is easy to limit the valve plate 2, so that when the cavity 4 is in a negative pressure state, the valve plate 2 cannot deform upward, thereby preventing the valve plate 2 from deforming into the water tank body 1, and thus improving the stability of the valve plate 2 in use.
[0038] As one implementation method, the outer edge of the valve plate 2 is located outside the maximum outer edge of the drain hole 1-2, ensuring that the valve plate 2 can completely wrap the drain hole 1-2, thereby sealing the drain hole 1-2.
[0039] It should be noted that the drain hole 1-2 is divided into multiple unit holes by the mounting bracket 1-3. Under normal conditions or when the vehicle air conditioner is turned on (the cavity 4 is in a negative pressure state), the valve plate 2 is in contact with the mounting bracket 1-3, and the valve plate 2 seals all the unit holes in one drain hole 1-2 to prevent hot air from entering the cavity 4 through the unit holes.
[0040] like Figure 3 and Figure 4 As shown, in one implementation, the valve plate 2 includes a valve plate body 2-1 and a connecting post 2-2 that are connected to each other. The connecting post 2-2 is located in the middle of the valve plate body 2-1. The connecting post 2-2 is inserted into the insertion hole in the middle of the mounting bracket 1-3, which ensures that the edge of the valve plate body 2-1 can be deformed, so as to separate the valve plate body 2-1 from the unit hole, thereby facilitating the discharge of liquid to the outside of the plastic water tank.
[0041] In this implementation, the cross-section of the valve plate body 2-1 is circular. Along the height direction of the liquid collection groove 1-1, the thickness of the valve plate body 2-1 decreases from the edge of the valve plate 2 towards the middle of the valve plate body 2-1, ensuring that the edge of the valve plate 2 has sufficient strength to prevent the edge of the valve plate 2 from breaking during deformation, and also ensuring that the valve plate 2 can return to its initial position after deformation.
[0042] Specifically, the upper surface of the valve plate body 2-1 is a plane, and the lower surface of the valve plate body 2-1 has a conical groove structure, so that the thickness of the valve plate body 2-1 decreases from the edge to the middle.
[0043] The valve plate body 2-1 is made of rubber or other elastic materials.
[0044] It should be noted that the valve plate body 2-1 can be cylindrical or cuboid, etc.
[0045] like Figure 3 As shown, as one implementation method, at least one limiting ring 1-4 is formed at the bottom of the water tank body 1 along the height direction of the liquid collection groove 1-1. The limiting ring 1-4 corresponds one-to-one with the drain hole 1-2. That is, a limiting ring 1-4 is provided below each drain hole 1-2. The drain hole 1-2 is located inside the limiting ring 1-4. The limiting ring 1-4 limits the valve plate 2 to prevent the valve plate 2 from deforming in the height direction perpendicular to the liquid collection groove 1-1, thereby improving the stability of the valve plate 2 in use.
[0046] Specifically, the height of the limiting ring 1-4 is greater than or equal to the maximum thickness of the valve plate body 2-1, ensuring that the limiting ring 1-4 can stably limit the valve plate body 2-1 and improve the stability of the valve plate 2 in use.
[0047] Meanwhile, the limiting ring 1-4 can protect the valve body 2-1, prevent external factors from causing deformation of the valve body 2-1, and further improve the stability of the valve body 2 in use.
[0048] As one implementation method, the inner diameter of the limiting ring 1-4 is greater than or equal to the diameter of the drain hole 1-2, ensuring that the drain hole 1-2 is completely located within the limiting ring 1-4, so that the valve plate 2 can stably seal the drain hole 1-2.
[0049] Furthermore, the valve body 2-1 and the limiting ring 1-4 are in clearance fit or transition fit, which facilitates the valve body 2-1 to seal the drain hole 1-2 and also improves the stability of the valve body 2 in sealing the drain hole 1-2.
[0050] like Figure 1 and Figure 2As shown, as one implementation method, a guide pipe 1-5 is also formed at the bottom of the water tank body 1 along the height direction of the liquid collection groove 1-1, and multiple drain holes 1-2 are located in the guide pipe 1-5 so as to guide the liquid discharged through the drain holes 1-2 through the guide pipe 1-5.
[0051] like Figure 5 As shown, in one implementation, the liquid collecting groove 1-1 includes a drainage surface 1-6 and multiple guide surfaces 1-7, with the multiple guide surfaces 1-7 respectively connected to the drainage surface 1-6; along the height direction of the liquid collecting groove 1-1, the drainage surface 1-6 is connected to the lowest position of the guide surface 1-7, and the drain holes are evenly distributed in the drainage surface 1-6.
[0052] The liquid is guided by the flow guide surface 1-7, which facilitates the accumulation of liquid above the drainage surface 1-6, increases the overall gravity of the liquid, and facilitates the deformation of the valve plate 2, so that the liquid is discharged through the drain hole 1-2 to the outside of the water tank body 1. At the same time, it can effectively prevent the liquid from remaining in the liquid collection groove 1-1, and prevent the liquid from flowing into the air conditioner with the airflow when the air conditioner is turned on.
[0053] like Figure 2 As shown, as one implementation, the main body 1 of the water tank also has a baffle plate 1-8. The baffle plate 1-8 is connected to the inner wall of the liquid collection groove 1-1 near the cavity 4 and near the outlet 4-2 to prevent liquid from flowing out of the cavity outlet 4-2 with the airflow.
[0054] As one implementation, an extension 3-1 is formed inside the upper cover 3, which extends toward the liquid collection groove 1-1, thereby making the cavity 4 U-shaped, thus preventing the liquid from flowing directly out of the cavity 4 with the airflow when the vehicle air conditioner is turned on.
[0055] As one implementation, the cavity 4 includes an inlet 4-1 and an outlet 4-2, and the lowest part of the extension 3-1 is lower than the lowest position of the outlet 4-2, thereby further preventing liquid from flowing directly out of the cavity 4 with the airflow.
[0056] like Figure 2 As shown, the working principle of this plastic water tank is as follows:
[0057] When the vehicle's air conditioning is not turned on, liquid flows into cavity 4 from inlet 4-1. Under its own weight, the liquid flows to drain surface 1-6. Due to the weight of the liquid, valve plate 2 deforms downwards, causing it to separate at least partially from drain hole 1-2. The liquid then flows out of the plastic drain channel from drain hole 1-2, and the liquid flows in the following direction: Figure 2 As shown by the dashed line in the image.
[0058] When the vehicle's air conditioning is turned on, air flows into cavity 4 from inlet 4-1 and out of cavity 4 from outlet 4-2. The high air velocity inside cavity 4 causes a decrease in air pressure. Under atmospheric pressure, valve plate 2 abuts against drain hole 1-2, sealing drain hole 1-2. The airflow direction is as follows: Figure 2 As shown by the dotted line in the diagram. During this process, the liquid flows into the cavity 4 from the inlet 4-1. Under its own weight, the liquid flows to the drain surface 1-6. When the weight of the liquid is greater than the force exerted by atmospheric pressure on the valve plate 2, the valve plate 2 deforms downward, and the liquid flows out of the plastic water tank from the drain hole 1-2.
[0059] Finally, it should be noted that the above are only some preferred embodiments of this application and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
