Description

Technical Field

[0001] This utility model belongs to the field of steam oven technology, specifically relating to a steam uniform distribution device for a single-door gas-fired steam oven. Background Technology

[0002] In traditional single-door gas steam ovens, the uniformity of steam distribution directly affects the heating efficiency and taste of food. In existing technologies, steam typically enters the cooking chamber through nozzles in fixed positions or airflow in a single direction. Fixed nozzles make it difficult to dynamically adjust the steam spray direction according to the placement of the food, resulting in a lack of concentrated steam supply to the food area. Consequently, a large amount of steam escapes directly into the empty area, increasing gas consumption. Utility Model Content

[0003] The purpose of this invention is to provide a steam uniform distribution device for a single-door gas-fired steam oven, which can concentrate steam to heat food more evenly, reduce heat energy waste, and reduce gas consumption.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A single-door gas-fired steam oven with uniform steam distribution device includes a gas-fired steam oven body, a steam heating chamber inside the gas-fired steam oven body, an opening on the front side of the gas-fired steam oven body that communicates with the steam heating chamber, and a door installed on the front side of the gas-fired steam oven body.

[0006] The steam heating chamber is fixedly connected to a main frame, and a row of positioning strips is fixedly connected to both sides of the main frame. The two rows of positioning strips are paired one to one to form a group.

[0007] The gas-fired steam oven is equipped with a steam generator inside. The steam generator is connected to two steam discharge groups via hoses. The two steam discharge groups are located on both sides of the main frame.

[0008] The steam discharge assembly includes multiple nozzle mounting plates installed inside the steam heating chamber. Multiple steam nozzles are fixedly connected to the nozzle mounting plates. The hoses are connected to the steam nozzles. The nozzle mounting plates can be installed at different heights inside the steam heating chamber.

[0009] Furthermore, two vertically arranged rods are fixedly connected inside the steam heating chamber and on both sides of the main frame. The nozzle mounting plate is slidably connected to the outside of the two rods. The nozzle mounting plate at the top and the nozzle mounting plate at the bottom are both end plates. A vertical adjustment component that can adjust the height of the end plate is fixedly connected to one side of the gas steam box body. An adaptive spacing adjustment component is provided between two adjacent nozzle mounting plates.

[0010] Furthermore, the adaptive spacing adjustment component is a return spring, which is fixedly connected between two adjacent nozzle mounting plates and sleeved on the outside of the vertical rod.

[0011] Furthermore, the vertical adjustment component includes two servo motors fixedly connected to the gas-fired steam oven body. The two servo motors are located on the upper and lower sides of the steam heating chamber, respectively. The output end of the servo motor is fixedly connected to a threaded rod located inside the steam heating chamber. A limit plate is threadedly connected to the outer side of the threaded rod, and the limit plate is slidably connected to the outer side of the vertical rod.

[0012] Furthermore, another return spring is fixedly connected between the limiting plate and the end plate.

[0013] Furthermore, electric push rods are fixedly connected to both sides of the gas-fired steam oven body, and the piston rods of the electric push rods are fixedly connected to a reinforcing plate located on one side of the multiple nozzle mounting plates.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention relates to a single-door gas-fired steam oven with a uniform steam distribution device. The device adjusts the steam outlet position according to the food placement location, allowing the steam to be concentrated in the area where the food is stored. Furthermore, by uniformly setting the steam nozzles, the steam can be evenly distributed in the area where the food is stored, thereby concentrating the steam to heat the food more evenly, reducing heat energy waste, and lowering gas consumption.

[0022] 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.

[0023] like Figures 1-4 As shown, a single-door gas-fired steam oven with uniform steam distribution device includes a gas-fired steam oven body 1, a steam heating chamber is provided inside the gas-fired steam oven body 1, a box opening 2 connected to the steam heating chamber is provided on the front side of the gas-fired steam oven body 1, and a box door 3 that can seal the box opening 2 is installed on the front side of the gas-fired steam oven body 1.

[0024] The steam heating chamber is fixedly connected to a main frame 4. A row of positioning strips 5 is fixedly connected to both sides inside the main frame 4. The two rows of positioning strips 5 are paired one to one to form a group. At this time, the food tray is placed on any group of positioning strips 5, and multiple trays are placed on multiple groups of positioning strips 5 respectively.

[0025] The storage tray is a rectangular tray with fixed strips on both sides. The two fixed strips on both sides can be placed on the two positioning strips 5 in the same group to complete the positioning.

[0026] The gas-fired steam oven 1 is equipped with a steam generator inside. The steam generator is connected to two steam outlet groups through a hose 9. The two steam outlet groups are located on both sides of the main frame 4. At this time, the steam generator is heated by gas combustion to generate steam. Then, the steam is blown onto the food on the tray through the hose 9 and the steam outlet groups to heat the food.

[0027] In order to concentrate heat energy to heat food, this technical solution improves the structure of the steam discharge unit, as detailed below. Figure 2 and Figure 4 As shown, the steam discharge assembly includes multiple nozzle mounting plates 7 installed inside the steam heating chamber. Multiple steam nozzles 8 are fixedly connected to the nozzle mounting plates 7. The hoses 9 are connected to the steam nozzles 8. The nozzle mounting plates 7 can be installed at different heights inside the steam heating chamber, thereby adjusting the height of the steam nozzles 8 and the discharge position of the steam. This allows the steam to be concentrated in the area where food is stored. Furthermore, by uniformly setting the steam nozzles 8, the steam can be evenly distributed in the area where food is stored, thereby concentrating the steam to heat the food more evenly, reducing heat energy waste and lowering gas consumption.

[0028] There are multiple ways to install the nozzle mounting plate 7, such as fixing a magnet or a clip to the nozzle mounting plate 7, and magnetically attaching or clipping it to different heights on the side wall of the gas steam oven body 1.

[0029] like Figures 2-4 As shown, in this technical solution, two vertically arranged rods 6 are fixedly connected inside the steam heating chamber and on both sides of the main frame 4. The nozzle mounting plate 7 is slidably connected to the outside of the two rods 6. The nozzle mounting plate 7 at the top and the nozzle mounting plate 7 at the bottom are both end plates. A vertical adjustment component that can adjust the height of the end plates is fixedly connected to one side of the gas steam box body 1. An adaptive spacing adjustment component is provided between two adjacent nozzle mounting plates 7. After the positions of the two end plates are adjusted, the positions of the remaining nozzle mounting plates 7 can be adjusted by the adaptive spacing adjustment component, so that the multiple nozzle mounting plates 7 are evenly distributed, thereby making the steam nozzles 8 on the multiple nozzle mounting plates 7 evenly distributed, and automatically adjusting the position of the steam nozzles 8 so that the steam nozzles 8 are vertically evenly distributed.

[0030] Specifically, the adaptive spacing adjustment component can be a spring or a magnet, preferably a return spring 13. The return spring 13 is fixedly connected between two adjacent nozzle mounting plates 7, and the return spring 13 is sleeved on the outside of the vertical rod 6. The return spring 13 can be positioned by the setting of the vertical rod 6 to reduce the offset of the return spring 13.

[0031] like Figure 2 and Figure 4 As shown, the vertical adjustment component includes two servo motors 12 fixedly connected to the gas-fired steam oven body 1. The two servo motors 12 are located on the upper and lower sides of the steam heating chamber, respectively. The output end of the servo motor 12 is fixedly connected to a threaded rod 11 located inside the steam heating chamber. The outer side of the threaded rod 11 is threadedly connected to a limiting plate 10. The limiting plate 10 is slidably connected to the outer side of the vertical rod 6. At this time, by starting the servo motor 12 to drive the threaded rod 11 to rotate, the limiting plate 10 can be pushed, so that the limiting plate 10 pushes the end plate and adjusts the height of the end plate.

[0032] Another return spring 13 can be fixedly connected between the limiting plate 10 and the end plate. When the limiting plate 10 moves to the end of the steam heating chamber, the return spring 13 can make the end plate maintain a certain distance from the upper and lower side walls of the steam heating chamber, so that the steam nozzles 8 on the multiple nozzle mounting plates 7 can be evenly distributed inside the steam heating chamber.

[0033] Electric push rods 14 are fixedly connected to both sides of the gas-fired steam oven body 1. The piston rod of the electric push rod 14 is fixedly connected to a reinforcing plate 15 located on one side of the multiple nozzle mounting plates 7. After the nozzle mounting plate 7 is moved, the electric push rod 14 can be activated to move the reinforcing plate 15 to abut against the nozzle mounting plate 7, thereby locking the position of the nozzle mounting plate 7 and improving the positioning stability of the steam nozzle 8.

[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.
