Description

Technical Field

[0001] The present invention relates to the field of accessories for recreational vehicles, and more particularly, to a modular kitchen device for recreational vehicles. Background Art

[0002] With socioeconomic development and shifting leisure preferences, the RV lifestyle, which combines home and travel, is becoming increasingly popular. As mobile homes, interior space in RVs is extremely valuable. To address the issues of cooking inside vehicles, including fumes and heat buildup, as well as the limited living space occupied, extending kitchen functions outside the vehicle has become a widely adopted technical solution. The current mainstream solution in the market is the pull-out external kitchen.

[0003] For example, patent publication number CN210478509U discloses a utility model device for an externally extendable kitchen for recreational vehicles. This device can be pulled out from a storage compartment and used outside the vehicle, free from space constraints within the vehicle. It is easy to operate, and the resulting fumes do not contaminate the interior. The stovetop slides in and out of the storage compartment via telescopic rails, making it very convenient to use and store. Furthermore, support rods provide strong support for the stovetop, allowing multiple gas stoves to be installed on the stovetop and used simultaneously with pots and pans. While this device provides external cooking capabilities, its structure is relatively rigid and its functionality is limited. It lacks the integration and flexible configuration of different kitchen modules. Simply pulling out the stovetop does not integrate other necessary kitchen features, such as a sink, worktop, or storage. Users still need to prepare and arrange other kitchen supplies, which is inconvenient. Furthermore, the simple linear pull-out method limits the layout of the operating area, and in confined external spaces, it may not provide the optimal operating angle and flow.

[0004] For example, Publication No. CN222793365U discloses a side-pull integrated stove for RVs. The side-pull main frame design significantly saves interior space. When not in use, the stove can be completely retracted into the side of the vehicle, freeing up more room for movement. Pre-set standardized stove mounting slots allow users to flexibly select and replace stoves based on their personal preferences and cooking needs, enhancing the ability to customize kitchen facilities. While emphasizing space savings and stove interchangeability, the design primarily focuses on the integrated stove and does not fully consider other kitchen modules. The side-pull design also presents the problem of limited operating space. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a modular kitchen device for a recreational vehicle, which has the capabilities of integration, diversified functions, flexible layout and easy use.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0008] The main frame is installed in the RV and has at least two upper and lower sliding rails inside the main frame, which are used to carry different kitchen modules respectively;

[0009] The kitchen module can be pulled out along the slide rails so that the kitchen module extends from the main frame to the outside of the RV for kitchen operation outside the RV;

[0010] At least one kitchen module is rotatable relative to the other kitchen modules,

[0011] The kitchen module includes storage units and operating units.

[0012] The storage unit is provided with a plurality of storage compartments, and the operating unit includes a water tank module and a gas stove module, and the gas stove module and the water tank module are rotatably connected via a rotating member.

[0013] The present invention is further configured as follows: the sink module includes a box body with a plurality of functional cavities and a bowl rack, a special-shaped drawer and a water filter rack placed in the corresponding functional cavities.

[0014] The bowl rack, the special-shaped drawer and the water filter rack are all movably connected to the box body.

[0015] The present invention is further configured as follows: the bowl rack includes a unit trough, two staggered storage frames, a cover plate and a rotating assembly.

[0016] The rotating assembly includes a short rod, a first rod, and a second rod symmetrically arranged on both sides of the storage frame. One end of the first rod and the second rod are rotatably connected to the groove wall of the unit groove. The first rod and the second rod are close to the groove wall of the unit groove, and the first rod and the second rod are arranged obliquely.

[0017] One end of the short rod is connected to the cover plate through an L-shaped piece, and the other end is synchronously connected to one end of the first rod and one end of the first storage frame through a first pin shaft.

[0018] The other end of the second rod is movably connected to the other end of the first storage frame through a second pin shaft.

[0019] The two ends of the second storage frame are movably connected to the first rod and the second rod through the third pin shaft and the fourth pin shaft respectively.

[0020] The present invention is further configured such that: the first pin and the second pin are on the same horizontal line, and the third pin and the fourth pin are on the same horizontal line.

[0021] The present invention is further configured as follows: the rotating part includes a channel steel hanger and a connector, a rotating shaft is provided on the channel steel hanger, a movable cavity for the rotating shaft to pass through is provided on the connector, one end of the connector is fixed to the gas stove module, and when the gas stove module is pushed, the connector rotates relative to the rotating shaft so that the gas stove module and the sink module form an angle.

[0022] The present invention is further configured as follows: a water filter rack is provided below the water tank module, and the water filter rack is movably connected to the water tank module so that the water filter rack can be pushed and pulled together with the water tank module.

[0023] The present invention is further configured such that a portable waterway quick connector for connecting to a waterway is provided at the bottom of the water tank module.

[0024] The present invention is further configured such that a portable gas quick connector for connecting to a gas line is provided at the bottom of the gas stove module.

[0026] Compared with the shortcomings of the prior art, the beneficial effects of the present invention are:

[0027] The unique design of the kitchen module, which is supported by upper and lower sliding rails within the main frame and can be pulled out and extended along the rails, allows the entire kitchen unit to be extended from the interior to the exterior of the RV. This breaks the limitations of the RV's interior space and provides users with a spacious and well-ventilated outdoor cooking environment. This is especially true for frying, stir-frying, and deep-frying, which prevents fumes from contaminating the interior of the RV, greatly improving cooking comfort and health.

[0028] The gas stove module can be rotated relative to the sink module. Combined with the limit device, the sink and gas stove can form a variety of operating layouts such as L-shaped, T-shaped or parallel, effectively improving the utilization efficiency and ergonomic comfort of the operating table, and avoiding the rigidity and inconvenience of traditional fixed kitchens.

[0029] The bowl rack's ingenious rotating component design allows the rack to be hidden under the sink when stored, taking up no countertop space. When in use, it automatically rises and unfolds, making it easier for users to place and retrieve dishes, and retracts smoothly after the operation, achieving a perfect combination of space utilization and ease of use, far exceeding traditional fixed bowl racks or simple drawer-style bowl baskets.

[0036] Reference Figures 1 to 6 An embodiment of a modular kitchen device for a recreational vehicle according to the present invention is further described, which specifically includes a main frame and a kitchen module.

[0037] The main frame serves as the supporting base of the entire modular kitchen device and is firmly installed at a specific position inside the RV, such as the side wall of the RV or the floor of the carriage. Its main function is to provide stable support and precise guidance for the kitchen module. At least two upper and lower layered slide rails 2 are arranged inside the main frame. In this embodiment, in order to ensure the load stability and smooth operation, two sets of heavy-duty telescopic slide rails 2 are arranged inside the main frame, which are respectively located on the upper and lower sides of the main frame.

[0038] The internal structure of the kitchen module is divided into a storage unit 4 and an operating unit. The main function of the storage unit is to provide necessary storage space for cooking tools, ingredients, tableware, etc., and a number of storage compartments 5 are provided on it.

[0039] The operating unit includes the core equipment for cooking and cleaning operations, namely the sink module 6 and the gas stove module 7. The two are designed to rotate, making them compact when stored and flexible when operated.

[0040] The design of the sink module 6 fully considers the needs of cleaning and draining. It mainly includes a box with several functional cavities, as well as a bowl rack 13, a special-shaped drawer 12 and a water filter rack 11 placed in the corresponding functional cavities. These components are movably connected to the box to achieve maximum flexibility and space utilization.

[0041] The bowl rack 13 comprises a unit trough body, two staggered storage frames (21, 22), a cover plate 20 and a rotating assembly. This structure enables the bowl rack to be automatically lifted and unfolded from a storage state (retracted in the unit trough) through a simple operation, making it convenient for users to take and place dishes. After the operation is completed, the bowl rack can be easily retracted to save space.

[0042] The first storage frame 21 is above the second storage frame 22 and slightly in front. When unfolded, the two can rise and extend forward at the same time. The cover 20 not only serves as a dust cover for the bowl rack, but also serves as the entrance to the operating mechanism. The bowl rack can be activated by lifting or pressing the cover 20. The cover has an integrated chopping board function.

[0043] The rotating assembly includes:

[0044] One end of the short rod 101 is connected to the cover 20 through the L-shaped piece 100, and the other end is synchronously connected to one end of the first rod 102 and one end of the first storage frame 21 through the first pin 201, which means that when the cover is lifted, the L-shaped piece and the short rod are linked.

[0045] The first and second rods 102, 103 are arranged at an angle, each with one end fixedly connected to the wall of the unit slot, allowing for rotation. The two rods are positioned close to the wall to maximize internal storage space. The other end of the first rod 102 is connected to the first pin 201. The other end of the second rod 103 is movably connected to the other end of the first storage frame 21 via the second pin 202. The second storage frame 22 is movably connected to the first and second rods 102, 103 at both ends via the third and fourth pins 103, 104, respectively.

[0046] The first pin 201 and the second pin 202 are on the same horizontal line, and the third pin 203 and the fourth pin 204 are on the same horizontal line. This horizontal line constraint ensures the stability of the mechanism movement, so that the storage frame remains relatively stable during the lifting process and avoids tilting.

[0047] When the user lifts the cover 20, it drives the L-shaped member and short rod 101 to rotate upward, lifting the other end of the short rod 101 upward (simultaneously driving the first rod 102 and the first storage frame upward). Because the fixed fulcrums of the first and second rods 102 are located below the unit slot wall, and the first and second pins are on the same horizontal line, when the first and second pins are pulled upward, the first and second rods 102, 102 will rotate upward about their fixed fulcrums. The first storage frame is connected to the short rod 101, first rod 102, and second rod 102 via the first and second pins, respectively, so their motion trajectories are pulled together.

[0048] The second storage frame is connected to the first and second rods 102, 102, via third and fourth pins (the third pin is on the first rod 102, and the fourth pin is on the second rod 102). Therefore, its motion trajectory is also controlled by the rotation of the first and second rods 102, 102. By carefully designing the lengths of the rods and the relative positions of the pins, when the cover 20 is raised, the two storage frames rise synchronously from the unit slots in a nearly horizontal or slightly upwardly tilted position and pop outward, making it easy to remove and place dishes. To store dishes, press down on the cover 20, the mechanism moves in the opposite direction, and the storage frames smoothly fall back into the unit slots, where they are completely covered by the cover 20, achieving ultimate space utilization and dustproofing.

[0049] The rotating part is a component that realizes the rotation of the gas stove module relative to the sink module, including a channel steel hanger 71 and a connector 72. The channel steel hanger 71 is fixed on one side of the sink module to provide a base for rotation. A rotating shaft is provided on the channel steel hanger 71, and the rotating shaft is vertically installed on the channel steel hanger 71 as the center of rotation.

[0050] One end of connector 72 is securely welded or bolted to the bottom frame of the gas stove module. The other end of connector 72 defines a movable cavity. This cavity is designed as a circular hole with an inner diameter slightly larger than the outer diameter of the rotating shaft, allowing the shaft to pass through. When stored, the gas stove module is parallel to the sink module. When ready to use, the user gently pushes the gas stove module, and connector 72 rotates in a plane about the rotating shaft to a predetermined angle, such as a 45-degree or 90-degree L- or T-shaped worktop, to optimize cooking space. A limiter is installed on the gas stove module to ensure that it can be tilted against the vehicle after being rotated into position, ensuring stability.

[0051] The special-shaped drawer 12 is a special design on the sink module 6. It is movably connected to the sink module 6 and can be pulled and pulled. Its special shape is that its shape is not a standard rectangle, but is designed according to the irregular space inside the sink module 6 or the shape of specific items. The purpose is to maximize the use of every inch of space under or on the side of the sink to store items that are usually difficult to place regularly.

[0052] The portable water quick connector 14 is provided at the bottom of the water tank module 6 for quickly connecting to the RV's external water supply system (such as a water tank pump pipe) or an external water source.

[0053] The portable gas quick connector 15 is provided at the bottom of the gas stove module 7 and is used for quickly connecting to the gas supply system (such as a liquefied gas tank) inside the RV.

[0054] The drain rack 11 is located below the sink module 12 and is designed as a push-pull drawer structure for draining washed vegetables or dishes.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
