Description

Technical Field

[0001] This utility model belongs to the technical field of RV kitchen equipment, specifically relating to a kitchen ventilation system for RVs. Background Technology

[0002] The kitchen ventilation system of an RV is an air circulation and purification device specifically designed for RV kitchens. It achieves air circulation, removes fumes, odors and moisture in the kitchen through mechanical or natural means. It is one of the core devices to ensure a safe and comfortable RV kitchen environment. Its structure and function need to be adapted to the characteristics of RVs, such as small space, multiple mobile scenarios and limited energy.

[0003] Currently, most RVs on the market install fans directly above the stove when configuring kitchen ventilation systems. This method exhausts cooking fumes and heat from the kitchen to the outside, achieving basic ventilation. While this design can solve the air circulation problem in the kitchen to some extent and ensure fresh air during cooking, its shortcomings cannot be ignored. First, this outward exhaust mode often lacks a flexible sealing mechanism and cannot be effectively adjusted and controlled according to actual needs. This means that the system remains open when ventilation is not needed. Second, since the exhaust vents are directly connected to the outside, dust and odors from the outside environment can easily enter the kitchen through the vents. This not only affects the cleanliness of the kitchen but may also threaten food hygiene and safety. In rainy weather or during insect-prone seasons, the open ventilation system cannot effectively prevent rainwater and insects from entering, which will undoubtedly further deteriorate the cooking environment and even directly affect the food preparation process and final food safety. Utility Model Content

[0004] The purpose of this invention is to provide a kitchen ventilation system for RVs that can tightly seal the exhaust vent when not in use, effectively isolating external dust, odors, rainwater, and insects, thereby maintaining the cleanliness of the kitchen and the hygiene and safety of food, and providing RV users with a healthier and more comfortable cooking environment.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A kitchen ventilation system for a motorhome includes a kitchen back panel, a ventilation plate fixedly connected to one side of the kitchen back panel, a fan rotatably connected to the inner side of the ventilation plate, closure components provided on both sides of the kitchen back panel near the ventilation plate, and detachable components provided on the ventilation plate.

[0007] Preferably, the closing assembly includes strip grooves formed on both sides of the kitchen back panel near the ventilation panel, and rectangular grooves formed at the bottom of the two strip grooves. Two bidirectional lead screws are rotatably connected to the inner walls of the rectangular grooves. A motor is fixedly installed on one side of the kitchen back panel, and the output end of the motor is fixedly connected to the bidirectional lead screw. Two sets of sliders are slidably connected to the surface of the bidirectional lead screw and located in the rectangular groove. Baffles are fixedly connected to the top two sides of each set of sliders, and the surface of the baffles is inserted into the strip groove.

[0008] Preferably, one set of the baffles has a strip-shaped slot on the side near the ventilation plate, and the other set of the baffles has a strip-shaped protrusion fixedly installed on the side near the strip-shaped slot.

[0009] Preferably, the detachable component includes threaded grooves at the four corners on both sides of the ventilation plate, each threaded groove being threaded with a screw, and protective covers being threadedly connected to both sides of the ventilation plate via the screws.

[0010] Preferably, a protective net is fixedly installed on the back of the kitchen back panel and on the side near the ventilation panel, and the protective net has a rectangular structure.

[0011] Preferably, a cabinet is installed at the bottom of the kitchen back panel, and a stove is fixedly installed at the top of the cabinet.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a kitchen ventilation system for RVs. By incorporating a closing component and a detachable component, a drive motor rotates a bidirectional lead screw within a rectangular slot. This rotation causes sliders on both sides to slide relative to or opposite to each other on the lead screw's surface. This movement of the sliders, along with the relative or opposite movement of baffles, closes or opens the ventilation openings. When the baffles are closed relative to each other, a sealed space is formed inside the kitchen, effectively blocking external environmental interference. When the baffles move away from each other, the fan inside the ventilation panel is activated, opening the ventilation openings and allowing air circulation. Protective covers can be easily installed on both sides of the ventilation panel by rotating the screw, or removed for cleaning or replacement of the fan. This device can tightly seal the exhaust vents even when not in use, effectively isolating external dust, odors, rain, and insects, thus maintaining kitchen cleanliness and food hygiene, providing RV users with a healthier and more comfortable cooking environment.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figure 1 - Figure 4 As shown, a kitchen ventilation system for a motorhome includes a kitchen back panel 1, a ventilation plate 2 fixedly connected to one side of the kitchen back panel 1, a fan 3 rotatably connected to the inner side of the ventilation plate 2, closing components provided on both sides of the kitchen back panel 1 near the ventilation plate 2, and detachable components provided on the ventilation plate 2.

[0022] The kitchen back panel 1 supports the closure assembly, ventilation panel 2, and detachable assembly. The ventilation panel 2 and fan 3 are designed to ventilate the RV's kitchen. The ventilation panel 2, as the main structure of the ventilation system, has a fan 3 connected to its inner side that can adjust the opening and closing of the vents, thereby effectively controlling the airflow inside the kitchen. The closure assembly further ensures that the kitchen remains relatively closed when the ventilation system is not in use, preventing external dust and odors from entering. The detachable assembly design not only facilitates cleaning and maintenance of the ventilation system but also improves the flexibility and practicality of the entire system, meeting the ventilation needs of the RV kitchen and providing RV users with a more comfortable and healthy cooking environment.

[0023] like Figure 2 and Figure 3As shown, the closing assembly includes strip grooves 4 on both sides of the kitchen back panel 1 near the ventilation panel 2. Rectangular grooves 5 are provided at the bottom of the two strip grooves 4. Two bidirectional lead screws 6 are rotatably connected to the two sides of the inner wall of the rectangular grooves 5. A motor 7 is fixedly installed on one side of the kitchen back panel 1, and the output end of the motor 7 is fixedly connected to the bidirectional lead screw 6. Two sets of sliders 8 are slidably connected to the surface of the bidirectional lead screw 6 and located in the rectangular grooves 5. Baffles 9 are fixedly connected to the top two sides of each set of sliders 8, and the surface of the baffles 9 is inserted into the strip grooves 4.

[0024] Specifically, the drive motor 7 drives the bidirectional lead screw 6 in the rectangular groove 5 to rotate. The rotation of the bidirectional lead screw 6 causes the sliders 8 on both sides to slide relative to or opposite to each other on the surface of the bidirectional lead screw 6, thereby causing the baffles 9 on the two sets of sliders 8 to move relative to or opposite to each other, thus closing or opening the vent. When the two sets of baffles 9 move relative to each other and close, a closed space is formed inside the kitchen to effectively block interference from the external environment. When the two sets of baffles 9 move away from each other, the fan 3 in the ventilation plate 2 is activated, and the vent opens accordingly, allowing the air inside the kitchen to circulate and achieving the effect of ventilation.

[0025] like Figure 3 As shown, one set of baffles 9 has a strip-shaped slot 10 on the side near the ventilation plate 2, and another set of baffles 9 has a strip-shaped protrusion 11 fixedly installed on the side near the strip-shaped slot 10.

[0026] When the two baffles 9 approach each other, the strip protrusion 11 is inserted into the strip slot 10 to completely close the vent, thus enhancing the airtightness of the kitchen.

[0027] like Figure 1 As shown, the detachable component includes threaded grooves 12 at the four corners on both sides of the ventilation plate 2, and a screw 13 is threaded into each threaded groove 12. Protective covers 14 are threaded to both sides of the ventilation plate 2 through the screws 13.

[0028] Specifically, the protective cover 14 is used to protect the kitchen fan 3 and prevent it from being damaged by bumps during travel. The protective cover 14 is made of a lightweight and sturdy alloy material, which can effectively resist external impacts without adding too much weight to the RV. Users can easily install the protective cover 14 on both sides of the ventilation plate 2 by rotating the screw 13, or remove it to clean or replace the fan 3.

[0029] like Figure 3 As shown, a protective net 15 is fixedly installed on the back of the kitchen back panel 1 and on the side near the ventilation panel 2. The protective net 15 has a rectangular structure.

[0030] The protective net 15 is designed to prevent foreign objects or insects from entering the kitchen through the ventilation openings, ensuring the cleanliness and safety of the kitchen environment. The protective net 15 adopts a fine mesh structure, which can effectively block the entry of insects as small as mosquitoes, while not affecting the normal air circulation.

[0031] like Figure 3 As shown, a cabinet 16 is installed at the bottom of the kitchen back panel 1, and a stove is fixedly installed on the top of the cabinet 16.

[0032] Specifically, Cabinet 16 is designed to be both practical and aesthetically pleasing. The stove installed on its top makes it convenient for users to cook in the RV. Cabinet 16 has multiple storage compartments inside, which can be used to store tableware, seasonings and other kitchen utensils in a categorized manner, making the kitchen space neat and orderly.

[0033] The working principle of this utility model is as follows: First, the drive motor 7 drives the bidirectional lead screw 6 in the rectangular groove 5 to rotate. The rotation of the bidirectional lead screw 6 causes the sliders 8 on both sides to slide relative to or opposite to each other on the surface of the bidirectional lead screw 6, thereby causing the baffles 9 on the two sets of component sliders 8 to move relative to or opposite to each other, thereby closing or opening the ventilation opening. When the two sets of baffles 9 move relative to each other and close, the internal space of the kitchen is sealed off.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
