Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam oven technology, and in particular to a gas-fired steam oven. Background Technology
[0002] High-temperature steam ovens, also known as superheated steam ovens, are steam ovens that use steam exceeding 100°C above the guide rails to steam food. High-temperature steam penetrates food more easily, retains its nutrients, and enhances its taste.
[0003] When using the above technology, the following technical problems were found in the existing technology: the existing steam ovens mainly use gas heating to add water to generate steam. When the steam oven generates a large amount of water vapor, it will cause the steam oven pressure to be too high and the internal environment of the steam oven to be too humid, which will lead to safety hazards such as explosion and damage to the steam oven. Therefore, it is necessary to release the water vapor at a constant pressure. However, the released water vapor cannot be recycled, so it is necessary to add water repeatedly, which is quite troublesome. To this end, we designed a gas-fired steam oven to provide another technical solution to the above technical problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A gas-fired steam oven includes a box body, a gas heater mounted at the bottom of the box body, a water outlet pipe fixed at the bottom of the box body and above the gas heater, several guide rails at both ends of the box body, partitions slidably connected to the inner side of the guide rails, an air suction hopper fixed at the top of the box body, a collection hood fixed through the top of the air suction hopper, a door rotatably connected to one side of the box body, and a circulation mechanism for discharging and recovering water vapor inside the box body at the top of the collection hood.
[0006] In a preferred embodiment of the gas-fired steam oven provided by this utility model, the circulation mechanism includes a water tank, a water pump, and a suction motor. The water tank is fixed to one end of the oven body, and the suction motor is fixed to the top of the collection hood. The output end of the suction motor is fixed to the water tank through a conduit, and the input end of the suction motor is fixed to the collection hood.
[0007] In a preferred embodiment of the gas-fired steam oven provided by this utility model, a valve is fixed to one side of the bottom of the water tank, the bottom of the valve is fixed to the water outlet pipe through a conduit, a water pump is fixed to one end of the tank body, the output end of the water pump is fixed to the water outlet pipe through a conduit, and the input end of the water pump is fixed to the water tank.
[0008] In a preferred embodiment of the gas-fired steam oven provided by this utility model, a water inlet pipe is provided at the top of the water tank, a drain pipe is fixed at the bottom of one side of the water tank, and a manual valve is fitted on the outside of the drain pipe.
[0009] In a preferred embodiment of the gas-fired steam oven provided by this utility model, a connecting block is fixed to one end of one side of the oven body. The connecting block is provided with a snap-fit mechanism, which includes a plug and a spring. Plugs are fixed to the top and bottom ends of the connecting block. Springs are fixed to the ends of the two plugs that are close to each other. The ends of the two springs that are close to each other are fixed to the connecting block, and the ends of the two plugs that are far apart from each other are slidably connected to the oven door.
[0010] In a preferred embodiment of the gas-fired steam oven provided by this utility model, the side of the two inserts that is far away from each other is arc-shaped.
[0011] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.
[0012] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:
[0013] This utility model provides a gas-fired steam oven. By injecting water into the water tank, a water pump is activated to transport the water inside the tank to the outlet pipe for evaporation, forming steam. The steam effectively moistens the food. However, excessive steam can lead to high pressure, requiring the activation of a suction motor to release the steam and pressure inside the oven. The suction motor transports the steam and pressure along the suction duct back into the water tank for recycling. The exhaust pipe on the water tank effectively releases the pressure and air, while the condensed water from the steam is collected. This cycle effectively saves a significant amount of water.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0022] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0024] Existing steam ovens primarily use gas heating to generate steam by adding water. When a large amount of steam is produced, it can cause excessive pressure and humidity inside the oven, potentially leading to safety hazards such as explosions or damage. Therefore, it's necessary to release the steam at constant pressure. However, the released steam cannot be recycled, requiring repeated water refills, which is quite cumbersome.
[0025] Please refer to Figures 1-4 A gas-fired steam oven includes a box body 1. A gas heater 12 is installed at the bottom of the box body 1. A water outlet pipe 13 is fixed at the bottom of the box body 1 and above the gas heater 12. Several guide rails 10 are provided at both ends of the box body 1. A partition 11 is slidably connected to the inner side of the guide rails 10. An air suction bucket 14 is fixed at the top of the box body 1. A collection hood 3 is fixed through the top of the air suction bucket 14 and passes through the box body 1. A box door 2 is rotatably connected to one side of the box body 1. A circulation mechanism for discharging and recovering water vapor inside the box body 1 is provided at the top of the collection hood 3.
[0026] When food needs to be cooked, the sliding partition 11 slides along the corresponding guide rail 10 according to the size of the food, making it easy to place food of different sizes inside the cabinet 1 for cooking. Then, the gas heater 12 is turned on to heat and cook the food. Water flows inside the water outlet pipe 13, which improves the taste and moisture of the food. During the cooking process, the water heating will generate a lot of water vapor. A lot of water vapor needs to be released in time to avoid excessive pressure caused by water vapor, which may lead to safety hazards.
[0027] The circulation mechanism includes a water tank 5, a water pump 9, and a suction motor 4. The water tank 5 is fixed to one end of the housing 1, and the suction motor 4 is fixed to the top of the collection cover 3. The output end of the suction motor 4 is fixed to the water tank 5 through a conduit, and the input end of the suction motor 4 is fixed to the collection cover 3. A valve 18 is fixed to one side of the bottom of the water tank 5. The bottom end of the valve 18 is fixed to the outlet pipe 13 through a conduit. The water pump 9 is fixed to one end of the housing 1. The output end of the water pump 9 is fixed to the outlet pipe 13 through a conduit, and the input end of the water pump 9 is fixed to the water tank 5. An inlet pipe 7 is opened at the top of the water tank 5, and a drain pipe 6 is fixed to the bottom of one side of the water tank 5. A hand valve is installed on the outside of the drain pipe 6.
[0028] Specifically, by injecting water into the water tank 5, the water pump 9 is activated to transport the water inside the water tank 5 to the water outlet pipe 13 for evaporation to form water vapor. The water vapor effectively moistens the food. However, excessive water vapor can lead to excessive pressure. Therefore, the suction motor 4 needs to be activated to discharge the water vapor and pressure inside the box 1. The suction motor 4 transports the water vapor and pressure along the suction hopper 14 to the water tank 5 for recycling. The exhaust pipe 8 on the water tank 5 effectively discharges the pressure and air, and the water vapor condenses and is collected. This cycle can effectively save a lot of water.
[0029] A connecting block 15 is fixed to one end of one side of the box 1. The connecting block 15 is equipped with a snap-fit mechanism, which includes a plug 16 and a spring 17. The top and bottom ends of the connecting block 15 are both fixed with plug 16. The side of the two plug 16 that is far away from each other is arc-shaped. The side of the two plug 16 that is close to each other is fixed with a spring 17. The side of the two springs 17 that are close to each other is fixed to the connecting block 15 respectively. The side of the two plug 16 that is far away from each other is slidably connected to the box door 2.
[0030] Specifically, when the door 2 needs to be sealed and closed with the body 1, the door 2 is rotated and slid with the connecting block 15. At this time, the door 2 presses against the insert block 16. When the door 2 passes through the insert block 16, the elasticity of the spring 17 drives the insert block 16 to lock the door 2, so that the door 2 and the body 1 can be sealed and connected.
[0031] When it is necessary to open the box door 2, the toggle block 16 is moved in a direction that brings them closer together, which effectively rotates and opens the box door 2.
[0032] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to specific implementations. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
