Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration equipment technology, specifically to a refrigerated truck compartment that facilitates the drainage of cold water. Background Technology
[0002] The core function of a refrigerated truck compartment is to maintain a low-temperature environment for freezing or preserving goods. Therefore, during the operation of a refrigerated truck, due to the low temperature inside the compartment, when the temperature of the inner walls of the compartment is lower than the dew point temperature of the air, water vapor in the air will condense into liquid water on the inner walls of the compartment.
[0003] Although condensation will flow downwards due to gravity after forming on the walls, the right-angle structure of the top and side walls of the refrigerated truck compartment hinders the smooth dripping of water. As a result, the condensed liquid water is affected by surface tension at the corners and tends to adhere to the gaps in the corners, gradually accumulating.
[0004] If this accumulated water is not cleaned up promptly, it can cause numerous damages to the refrigerated truck compartment. For example, the interior walls of refrigerated truck compartments are mostly made of metal (such as stainless steel and aluminum alloy), and accumulated water will directly contact the metal surfaces at the corners. Especially when the water mixes with residual juices and salt from goods (such as seafood and meat), it will form an electrolyte, exacerbating electrochemical corrosion. Over time, rust spots, perforations, and even a decrease in structural strength may appear at the corners. In addition, refrigerated truck compartments usually have sealing strips or welded seams at the corners. Long-term immersion in water can cause the sealing strips to age and fall off, or the welds to rust and loosen. Utility Model Content
[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a refrigerated truck compartment that facilitates the drainage of cold water, so that water accumulated at the corner between the top side wall and the side side wall of the refrigerated truck compartment can be cleaned in a timely manner.
[0006] To achieve the above objectives, this utility model provides a refrigerated truck body that facilitates cold water drainage, comprising a truck body body and a water drainage assembly, wherein the water drainage assembly includes:
[0007] A capillary water-guiding layer, which is a fiber fabric made of a highly hydrophilic and low-temperature resistant material, is disposed on the side wall of the main body of the carriage and fixedly connected to the main body of the carriage, and the top of the capillary water-guiding layer extends to the corner of the side wall and the top wall of the main body of the carriage; and

[0013] Furthermore, the water intake assembly also includes a liquid level sensor, which is disposed on the water collection tank;
[0014] The control valve is a solenoid valve, and the control valve and the liquid level sensor are electrically connected to the controller.
[0015] The liquid level sensor is used to detect the liquid level information in the water collection tank and convert the detected information into a corresponding electrical signal and transmit it to the controller.
[0016] The controller is used to convert the received electrical signal into a corresponding control signal and transmit it to the solenoid valve to control the working state of the solenoid valve.
[0017] Furthermore, the water intake assembly also includes a filter device. The bottom side wall of the water collection tank is provided with an installation groove, which is connected to the outlet of the water collection tank. The filter device is disposed in the installation groove.

[0024] The beneficial effects of this utility model are:
[0025] The refrigerated truck body provided in this embodiment, which facilitates cold water drainage, utilizes a capillary drainage layer to guide water accumulated at the corners of the side and top walls of the truck body. Its simple structure requires no modification to the existing truck body while achieving cold water drainage. It also requires no additional power equipment and effectively drains water from the corners of the side and top walls, resulting in low energy consumption.

[0040] like Figure 1-5As shown, this utility model provides a refrigerated compartment that facilitates cold water diversion, including a compartment body 100 and a water diversion assembly, which includes a capillary water diversion layer 210 and a water collection tank 220.
[0041] The capillary water-guiding layer 210 is a fiber fabric made of a highly hydrophilic and low-temperature resistant material. Specifically, the capillary water-guiding layer 210 is a capillary polyester fiber felt with a thickness of 5-10 mm. The capillary water-guiding layer 210 is disposed on the side wall of the carriage body 100 and fixedly connected to the carriage body 100. The top of the capillary water-guiding layer 210 extends to the corner of the side wall and the top wall of the carriage body 100.
[0042] During operation, due to the small pores of the capillary water-guiding layer 210, the condensate water collected at the corners of the top and side walls of the main body 100 of the carriage will rapidly diffuse and penetrate downwards along the pores between the fibers of the capillary water-guiding layer 210 under the action of surface tension. This guides the condensate water collected at the corners of the top and side walls of the main body 100 of the carriage downwards to the side walls of the main body 100 of the carriage, thereby achieving the purpose of timely guiding away the water accumulated at the corners of the top and side walls of the main body 100 of the carriage, so as to avoid water accumulation at the corners of the top and side walls of the main body 100 of the carriage.
[0043] Preferably, the capillary water-guiding layer 210 is bonded to the side wall of the carriage body 100 to facilitate assembly.
[0044] Preferably, the capillary water-conducting layer 210 is specially treated (e.g., by adding antifreeze) so that it remains hydrophilic at temperatures below -20°C and does not freeze or become clogged.
[0045] The water collection tank 220 is installed on the bottom side wall of the main body 100 of the carriage, and is located at the corner between the bottom side wall and the side wall of the main body 100 of the carriage. During operation, the capillary water guiding layer 210 guides the water accumulated on the side wall of the main body 100 of the carriage, as well as the water that was originally condensed on the side wall of the main body 100 of the carriage, to flow along the side wall of the main body 100 of the carriage and into the water collection tank 220 under the action of gravity, thereby achieving the purpose of collecting condensate.
[0046] The refrigerated truck body provided in this embodiment, which facilitates cold water drainage, has a simple structure. It achieves cold water drainage without requiring modifications to the existing truck body 100, and requires no additional power equipment. It can also drain water accumulated at the corners of the side and top walls of the truck body 100, resulting in low energy consumption. Even when the truck body is stationary or has minimal water accumulation, capillary action can still effectively guide water away from the corners of the side and top walls of the truck body 100. Furthermore, it can be installed on an existing truck body 100, offering greater versatility without occupying internal space.
[0047] like Figure 1 and Figure 3 As shown, in this embodiment, the water intake assembly also includes a water collection tank 230, a water intake pipe 231, and a drain pipe 232.
[0048] A water collection tank 230 is located below the water collection trough 220 and is fixedly connected to the main body 100 of the carriage. The inlet end of the water inlet pipe 231 is connected to the outlet end of the water collection trough 220, and the outlet end is connected to the inlet end of the water collection tank 230. A drain pipe 232 is connected to the water collection tank 230, and a control valve 233 is installed on the drain pipe 232. It should be noted that the control valve 233 can be either manual or electric.
[0049] During operation, the condensate collected in the water collection tank 220 enters the water collection box 230 through the water inlet pipe 231 under the action of gravity. Opening the control valve 233 allows the water in the water collection box 230 to be discharged from the drain pipe 232. At the same time, closing the control valve 233 can prevent outside air from entering the main body 100 of the carriage through the drain pipe 232, the water collection box 230, the water inlet pipe 231, etc.
[0050] like Figure 1 , Figure 3 and Figure 5 As shown, in this embodiment, the water intake assembly also includes a liquid level sensor 234, which is disposed inside the water collection tank 230.
[0051] The control valve 233 is a solenoid valve, and the control valve 233 and the liquid level sensor 234 are electrically connected to the controller 235. Specifically, the liquid level sensor 234 is electrically connected to the signal input circuit of the controller 235, and the control valve 233 is electrically connected to the signal output circuit of the controller 235.
[0052] The level sensor 234 is used to detect the level information of the water collection tank 230 and convert the detected information into an electrical signal, which is then transmitted to the controller 235. The controller 235 is used to convert the received electrical signal into a corresponding control signal and transmit it to the solenoid valve to control the working state of the solenoid valve.
[0053] Specifically, during operation, when the level sensor 234 detects that the liquid level in the water collection tank 230 is greater than or equal to the first preset value, the level sensor 234 transmits the detected information to the controller 235, thereby controlling the control valve 233 to open, so as to drain the water accumulated in the water collection tank 230; when the level sensor 234 detects that the liquid level in the water collection tank 230 is less than or equal to the second preset value, the level sensor 234 transmits the detected information to the controller 235, thereby controlling the control valve 233 to close, so as to seal the drain pipe 232.
[0054] like Figure 1 and Figure 3 and Figure 4 As shown, in this embodiment, the water intake assembly also includes a filter device 240. The bottom side wall of the water collection tank 220 is provided with an installation groove, which is connected to the water outlet of the water collection tank 220. The filter device 240 is installed in the installation groove.
[0055] During operation, the filter device 240 filters out impurities in the accumulated water, thereby preventing pipe blockage.
[0056] Specifically, the filter device 240 includes a mounting base 241 and a filter screen 242.
[0057] The mounting base 241 is provided with a water outlet hole and is adapted to the mounting groove. A permanent magnet 243 is provided on the mounting base 241. The permanent magnet 243 fixes the mounting base 241 in the mounting groove, facilitating disassembly and installation. It also allows for timely removal and cleaning of the filter device 240 to remove impurities. The filter screen 242 is located at the water outlet hole.
[0058] like Figure 1 and Figure 2 As shown, in this embodiment, the water-guiding assembly further includes a siphon tube 250, which is disposed at the bottom of the capillary water-guiding layer 210. The first end of the siphon tube 250 is fixedly connected to the bottom of the capillary water-guiding layer 210, and the second end extends downward. The connection between the siphon tube 250 and the capillary water-guiding layer 210 is kept sealed.
[0059] During operation, once a certain amount of water accumulates at the bottom of the capillary water-guiding layer 210, as the water enters the siphon tube 250, the air inside the siphon tube 250 is gradually expelled, creating a localized vacuum environment. Under atmospheric pressure, the water on the capillary water-guiding layer 210 is continuously drawn into the siphon tube 250 and flows rapidly along the pipe to the bottom of the carriage body 100, thereby improving the water-guiding effect.
[0060] In the water-guiding assembly provided in this embodiment, by setting a siphon tube 250 at the bottom of the capillary water-guiding layer 210, the capillary effect of the capillary water-guiding layer 210 and the siphon effect of the siphon tube 250 are combined, thereby achieving the purpose of improving the water-guiding effect.
[0061] Preferably, the siphon tube 250 is a silicone tube with a diameter of 10-15mm.
[0062] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
