Description

Technical Field

[0001] This utility model relates to the technical field of steam ovens, specifically a multi-layer steam oven. Background Technology

[0002] A steam oven is a device that uses the heat of steam to achieve heat exchange. For example, in the process of heating pasta, the pasta is placed in a steam oven and heated by hot steam in a sealed space, making it easier to eat. In the existing technology, the water supply of the steam oven is relatively inconvenient due to frequent manual water addition. Automatic water supply controlled by microcomputer is costly. In addition, the existing steam oven lacks water droplet recycling, which causes water droplets to accumulate on the top of the oven and eventually fall down, affecting the processing quality. Therefore, in order to solve this problem, this paper was developed to design a multi-layer steam oven. Utility Model Content

[0003] The purpose of this invention is to provide a multi-layer steam oven with upward steaming to solve the problems mentioned in the background art.

A fixed cylinder 14 is installed on one side inside the steam box 5, and a vertical rod 15 is installed inside the fixed cylinder 14. The top of the vertical rod 15 penetrates the top of the fixed cylinder 14 and is connected to a float ball 16. A cabinet is installed inside the insulated shell 3. The cabinet 1 has a flow-rectifying grille 2 installed at the bottom inside the cabinet 1. Multiple perforated plates 12 are installed at equal intervals inside the cabinet 1. Pads 18 are installed at the top of both sides inside the cabinet 1. A sliding groove 19 is opened on one side of the pad 18. A collection box 11 is set at the top of the pad 18. A slider 17 is installed at the bottom of the collection box 11. A steam collection hood 9 is installed at the top of the cabinet 1. Two guide plates 10 are installed at the middle position of the top of the steam collection hood 9. Cabinet doors 13 are hinged to both sides of one end of the cabinet 1.

[0021] The bottom of the guide plate 10 is positioned directly above the collection box 11, and the two guide plates 10 are arranged in a V-shape in space.

[0022] The slider 17 is L-shaped, and one side of the slider 17 passes through one side of the pad 18 and extends into the inside of the groove 19. The thickness of the inside of the groove 19 is the same as the thickness of one side of the slider 17. The top of the groove 19 is in contact with the bottom of the collection box 11.

[0023] One end of the water inlet pipe 6 passes through the heat insulation shell 3 and one side of the steam box 5 and extends into the steam box 5, and the horizontal height of the water tank 7 is higher than the horizontal height of the steam box 5.

[0024] The float 16 is positioned directly below one end of the water inlet pipe 6, with the top of the float 16 in contact with the bottom of the water inlet pipe 6, and the diameter of the float 16 is larger than the internal diameter of the water inlet pipe 6.

[0025] The fixing cylinder 14 is positioned above the electric heating grid 4, and the inner wall of the fixing cylinder 14 is in contact with the outer side of the vertical rod 15;

[0026] The cabinet 1 is made of heat-insulating metal material, and the top of the steam box 5 passes through the bottom of the cabinet 1 and extends into the interior of the cabinet 1. The heat-insulating shell 3 is made of heat-insulating metal material.

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in the operation of this device, firstly, the device has a steam box 5 and a water tank 7. Water is pre-filled into the water tank 7 via the water inlet pipe 8. Then, guided by the water inlet pipe 6, the water is automatically transported into the steam box 5. Inside the steam box 5, an electric heating grid 4 is installed. An external power source can be used to heat the electric heating grid 4, thereby heating the water inside the steam box 5 and generating hot steam, which is then transported into the cabinet 1. Because the cabinet 1 has a flow-regulating grille 2, the hot steam flows through... During the process, the guiding effect of the rectifier grille 2 allows the hot steam to move evenly and vertically upwards after passing through the interior of the rectifier grille 2, thereby heating the interior of the cabinet 1. Therefore, food requiring heating can be placed above the perforated plate 12 and heated by the hot steam, thus achieving the basic function of this device. To ensure the efficiency and quality of the device, a float ball 16 is incorporated. When the device uses the electric heating network 4 to heat the water inside the steam box 5, the evaporation of water causes the water level to drop, resulting in buoyancy for the float ball 16. The function of the float 16 moves downwards synchronously, thereby releasing the seal on the inlet pipe 6. This allows water from the water tank 7 to automatically be added to the steam tank 5 through the inlet pipe 6, causing the water level to rise again until the float 16 is blocked again at one end of the inlet pipe 6. This achieves the automatic water addition effect of the device, ensuring a continuous supply of hot steam and guaranteeing the efficiency and quality of the device. Furthermore, the device also features a steam collection hood 9 and a guide plate 10. As the hot steam moves upwards, it accumulates at the top of the steam collection hood 9, resulting in a large number of water droplets on the surface of the top of the steam collection hood 9. This facilitates the... The device treats water droplets by incorporating a guide plate 10. The guide plate 10 directs the water droplets along its surface, allowing them to fall automatically into the collection box 11 for collection. This effectively prevents water droplets from falling vertically onto the heated food and causing damage. Furthermore, the collection box 11 is slidably connected to the pad 18 via a sliding structure of slider 17 and groove 19, facilitating easy installation and removal of the collection box 11 for transferring the collected water droplets. The device is simple to operate, structurally stable, low-cost, and offers good processing quality and efficiency.
