Description

Technical Field

[0001] This utility model relates to the field of RV water tanks, and in particular to an RV water tank. Background Technology

[0002] With the development of society, motorhomes are becoming increasingly popular. Many people enjoy traveling in motorhomes. The fresh water tank in a motorhome is usually located in a low, center position (under the floor or bed) to lower the center of gravity and facilitate pipe connections. The fresh water tank generally stores clean drinking water and domestic water for cooking, washing vegetables, brushing teeth, showering, etc. However, when a motorhome is driven to a colder region or in winter, the fresh water tank is prone to freezing, rendering it unusable.

[0003] Therefore, the applicant designed a motorhome water tank structure that can utilize warm air to circulate outside the water tank while simultaneously preventing the water tank from freezing. Utility Model Content

[0004] This application provides a water tank for a motorhome, employing the following technical solution:

[0005] A mobile home water tank includes a shell, inside which a water tank is disposed. A limiting and fixing boss is provided on the side of the water tank, and the limiting and fixing boss contacts and fits against the inner side of the shell. A water inlet and a water outlet are provided on the side of the water tank, and an air inlet and an air outlet are provided on the side of the shell. Warm air enters from the air inlet, and the incoming warm air quickly circulates in the gap between the water tank and the shell, and the circulating warm air is blown out from the air outlet.

[0006] Optionally, a water level gauge is installed on the water tank to display the water level inside the tank.

[0007] Optionally, the water tank is also equipped with a vent to expel air from inside the tank.

[0008] Optionally, an air guide protrusion is provided on the bottom side of the water tank, and the air guide protrusion contacts the shell.

[0009] Optionally, the air guide protrusion can be arc-shaped.

[0010] Optionally, a water tank fixing hole is provided on the outer side of the shell, and the water tank fixing hole is connected and fixed to the RV.

[0011] Compared with existing technologies, the advantages of this utility model are as follows: A limiting and fixing protrusion is provided between the shell and the water tank to ensure stability. Simultaneously, this protrusion allows for a gap between the water tank and the shell, enabling the flow of warm air while preventing overheating and ice formation inside the water tank. The entire process delivers warm air generated by the air conditioner or engine into the shell, allowing it to circulate through the gap between the shell and the water tank, thus heating the entire water tank and achieving warm air circulation within the shell, thereby realizing the multi-functionality of the RV.

[0019] The technical solutions of various embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] An embodiment of this utility model provides a water tank for a motorhome.

[0023] Example: Figure 1-5 As shown, a RV water tank includes a housing 1, within which a water tank 2 is housed. A limiting and fixing protrusion 4, cylindrical in design, is provided on the side of the water tank 2. The protrusion 4 contacts and fits snugly against the inner side of the housing 1 to prevent the water tank 2 from swaying within the housing 1. An inlet 301 and an outlet 302 are provided on the side of the water tank 2. A water level gauge 201 is installed on the water tank 2 to display the water level. An vent 202 is also provided on the water tank 2 to expel air from within, allowing for better water intake and exhaust. The inlet 301 and outlet 302 of the water tank 2 extend beyond the outer side of the housing 1 and are connected to the water inlet and outlet pipes of the RV.

[0024] An air inlet 501 and an air outlet 502 are provided on the side of the housing 1. The air inlet 501 is connected to the air conditioning vent of the RV. The warm air blown out by the air conditioner enters through the air inlet 501 and flows quickly through the gap between the water tank 2 and the housing 1. As the warm air flows between the water tank 2 and the housing 1, it can raise the temperature of the water tank 2, thereby raising the internal temperature of the water tank 2 and preventing the inside of the water tank 2 from freezing. The warm air in the housing 1 finally comes out through the air outlet 502. At the same time, an air guide protrusion 401 is provided on the bottom side of the water tank 2. The air guide protrusion 401 contacts the housing 1. The air guide protrusion 401 can also be set in an arc shape to guide the warm air.

[0025] A water tank fixing hole 101 is provided on the outer side of the shell 1. The water tank fixing hole 101 is connected and fixed to the RV, thereby fixing the shell 1 to the bottom of the RV.

[0026] Working principle: The housing 1 is fixed to the bottom of the RV through the water tank fixing hole 101. The limiting fixing boss 4 and the air guide boss 401 set on the water tank 2 fit and fix the entire water tank 2 inside the housing 1, thereby preventing the water tank 2 from shaking inside the housing 1. The water inlet 301 is located on the upper side of the water tank, and the water outlet 302 is located on the bottom side of the water tank. Water is introduced into the water tank 2 through the water inlet 301 and at the same time, warm air, that is, the air conditioner's warm air, enters through the air inlet 501. The warm air flows through the gap between the housing 1 and the water tank 2, heating the outside of the water tank 2. The warm air is discharged from the air outlet 502.

[0027] Water tank 2 is usually made of plastic, which can effectively conduct heat.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects. The scope of this invention is defined by the appended claims, not by the foregoing description, and is therefore intended to encompass all variations falling within the meaning and scope of equivalents of the claims. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
