Description

Technical Field

[0001] This utility model belongs to the field of commercial kitchen equipment, and in particular relates to a display steamer platform for food that is heated evenly. Background Technology

[0002] A steamer is a large commercial kitchen appliance that uses heat sources such as electricity, gas, or electromagnetic induction to generate steam for cooking food. Its interior typically uses multiple layers of stainless steel steaming trays as containers, achieving efficient and even heating through steam penetration. It is suitable for cooking a variety of ingredients, including rice, noodles, seafood, and meat. Due to its high efficiency, energy saving, and large capacity, steamers are widely used in large canteens and catering establishments such as hotels, schools, factories, and hospitals to meet the needs of group catering.

[0003] However, existing steam cabinet designs primarily focus on their cooking functions. For example, the multi-functional commercial steam cabinet disclosed in utility model patent CN217471710U generally lacks an integrated food display platform. This deficiency leads to significant limitations in modern dining environments such as open kitchens. In open kitchen settings, customers expect to see the finished products directly for selection. Existing steam cabinets, being enclosed and opaque, prevent diners from directly observing the type, color, and state of the food inside, thus failing to provide this intuitive and transparent dining experience. This makes it difficult for diners to accurately select their desired food, potentially leading to ordering errors and food waste. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the present invention provides a display steamer platform for food to be heated evenly, including a steamer body, a display stand on the top of the steamer body, a steam outlet for releasing steam at the bottom of the display stand, a display board on the top of the display stand, and an external air hole on the display board.

[0005] The display panel is evenly spaced with external air holes of various diameters. The external air holes closer to the steam outlet have smaller diameters, while the external air holes farther from the steam outlet have larger diameters.

[0006] The steam outlet is located on the central axis of the bottom of the display stand. A steam distribution groove is also fixedly installed at the corresponding position of the central axis on the bottom of the display stand. The steam distribution groove covers the steam outlet and has internal air holes on both sides of the steam distribution groove parallel to the central axis. The display panel is continuously spliced ​​together from several steam plates. The external air holes are set on the steam plates. The diameter of the external air holes closer to the central axis is smaller, and the diameter of the external air holes farther away from the central axis is larger.

[0007] The bottom of the display stand is provided with a fixing hook, and the top of the air distribution channel is provided with a snap-fit ​​strip hole that matches the fixing hook. The fixing hook passes through the snap-fit ​​strip hole from bottom to top and detachably snaps and fixes the air distribution channel to the display stand.

[0008] The bottom of the display stand is equipped with a drain pipe for draining water to the outside of the display steamer platform, and the drain pipe extends to the outside of the display steamer platform.

[0009] The main body of the steamer includes a cabinet shell, inside which a water tank and several steam boxes are fixedly installed. The water tank is equipped with a heating structure to form a steam generator, and the water tank is connected to each steam box through a separate steam pipe.

[0010] The water tank extends upwards to the display stand, and the water inlet of the water tank is located inside the display stand, with a water tank cover installed at the water inlet.

[0011] The display stand has N steam outlets and X steam chambers inside the cabinet, where N = X + 1. One steam outlet is directly connected to the water tank via a steam pipe, and the other steam outlets are connected to the top of the steam chambers via steam pipes.

[0012] The display stand is equipped with a drain pipe at the bottom for draining water to the outside of the display steamer platform. The drain pipe is equipped with a drain valve and extends to the outside of the display steamer platform. A circulating water pipe is also provided at the bottom of the display stand, which is connected to a water tank.

[0013] The beneficial effects of this utility model are as follows: Based on the traditional horizontal steamer structure, an improvement is made by adding a display stand to the top of the steamer. This display stand is connected to the core steam generating structure of the steamer through a steam diversion channel. A portion of the steam generated by the steamer itself is used to continuously maintain the heat of the food displayed on the display stand, thus connecting the three core functions of efficient steaming, intuitive display, and constant temperature protection. While increasing the visual display capability of the steamer, it effectively avoids the sudden temperature drop and taste deterioration caused by food exposure, and significantly enhances the applicability of the steamer in open kitchen environments that emphasize transparency and real-time selection.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] As attached Figure 1-8 The steamer platform shown includes a steamer body 1, which is the main structure supporting the heating function. The steamer body 1 includes a stainless steel shell, inside which a water tank 2 and three steam chambers 3 are fixedly installed. The three steam chambers 3 and the water tank 2 are arranged sequentially along the central axis of the long side. The water tank 2 contains a heating structure that forms a steam generator. The water tank 2 is connected to each steam chamber 3 via individual steam pipes. The heating structure in the water tank 2 converts electrical energy into heat energy, causing liquid water to rapidly vaporize into steam. The steam is delivered to each steam chamber 3 through separate pipes. The steam supply path for each steam chamber 3 is independent. By adjusting the valve opening of the corresponding pipe, the steam pressure and flow parameters can be adjusted according to the different types or volumes of food in different steam chambers 3. This structure ensures that the uniformity of steam distribution within each steam chamber 3 is not affected by the operating status of other steam chambers 3, avoiding pressure fluctuations that occur when multiple steam chambers 3 share a single steam channel.

[0024] The main body 1 of the steam cabinet has a display stand 4 on top. The water tank 2 extends upwards to the display stand 4, and the water inlet of the water tank 2 is located inside the display stand 4, allowing the operator to directly access the water inlet while standing. The opening of the water tank 2 is equipped with a water tank cover, which is an openable and closable component covering the water inlet. Specifically, it can form a sealed space by cooperating with a rubber sealing ring and a flange groove. The display stand 4 has three steam outlets 5 arranged along the central axis of its long side at the bottom for releasing steam. At the same time, the display stand 4 also has a fourth steam outlet 5a near the center of its bottom. That is, the display stand 4 has a total of four (N=4) steam outlets 5 and 5a. There are three (X=3) steam chambers 3 inside the cabinet, N=X+1. One steam outlet 5a near the center of the bottom of the display stand 4 is directly connected to the water tank 2 through a steam pipe, and the other three steam outlets 5 arranged along the central axis of their long side are connected to the top of their respective steam chambers 3 through steam pipes. When steamer 3 heats food, the waste steam collected at its top is guided through steam pipes to the corresponding steam outlet 5 of display stand 4, forming the main steam supply source. Waste steam from each steamer 3 can be directionally recovered and utilized. When the main steam supply is insufficient to maintain the heat retention of display stand 4, the independent steam outlet 5a directly connected to water tank 2 is activated, supplementing the supply with fresh steam not used for heating in steamer 3. When steamer 3 is not heating food, the independent steam outlet 5a connected to water tank 2 can be used as a separate steam source. By establishing two steam supply paths, both directional recovery of waste steam and the preservation of an independent fresh steam replenishment channel are achieved, maintaining a stable temperature for display stand 4 while reducing energy waste.

[0025] The bottom of the display stand 4 is also equipped with two drain pipes 6 for draining water to the outside of the display steamer platform. Each drain pipe 6 has a drain valve and extends outside the platform to direct the discharge of condensate or cleaning wastewater. The bottom of the display stand 4 also has two circulating water pipes 7, both connected to the water tank 2, to guide uncontaminated condensate back to the tank for reuse. Steam condenses into liquid water within the display stand 4. When wastewater needs to be discharged, the drain valve opens, allowing water to flow through the drain pipes 6 to the external drainage system, preventing water accumulation that could corrode components or breed bacteria. Uncontaminated condensate flows back to the water tank 2 through the circulating water pipes 7, where it is heated and converted back into steam, forming a closed-loop water resource system. The drain valve can be configured as a solenoid valve and linked to a water level sensor, automatically opening to drain water when the water level exceeds a threshold. The circulating water pipes 7 can be equipped with a filter to intercept impurities before being transported to the water tank 2.

[0026] At the bottom of the display stand 4, corresponding to the central axis, a gas distribution groove 8 is fixedly installed. The gas distribution groove 8 covers the steam outlet 5, the inlet of the drain pipe 6, and the inlet of the circulating water pipe 7. Specifically, the bottom of the display stand 4 is provided with four fixing hooks 9, arranged in a square array and symmetrically arranged in pairs on both sides of the central axis. The top of the gas distribution groove 8 is provided with four locking strip holes that correspond one-to-one with the fixing hooks 9. The fixing hooks 9 pass through the locking strip holes from bottom to top and detachably lock the gas distribution groove 8 to the display stand 4. Specifically, the locking strip hole refers to the elongated hole on the top of the gas distribution groove 8 that matches the shape of the fixing hook 9. It can be a straight or L-shaped slot, and its length direction is parallel to the axis of the gas distribution groove 8. This design allows the gas distribution groove 8 to move in a specific direction during installation to achieve locking or detachment. On both sides of the steam distribution trough 8 parallel to the central axis, there are multiple evenly spaced internal air holes 10. The internal air holes 10 are used to divert steam laterally to the areas on both sides of the display panel. The lateral diversion function of the steam distribution trough 8 can prevent the steam from being released in a concentrated manner along the central axis, which would cause the central area to overheat. The internal air holes 10 can be implemented by using equally spaced circular holes or strip holes. The top of the display platform 4 is provided with a display panel, which is composed of three steam plates 11 continuously spliced ​​together. The splicing structure of the steam plates 11 allows for the individual disassembly and replacement of damaged units during maintenance without the need to remove the entire display panel. Each steam plate 11 is evenly spaced with external air holes 12 of various diameters. The diameter of the external air holes 12 is smaller the closer to the central axis and larger the further away from the central axis, so as to achieve the effect that the diameter of the external air holes 12 is smaller the closer to the steam outlet 5 and larger the further away from the steam outlet 5. The high-pressure steam at steam outlet 5 experiences flow restriction as it passes through the small-diameter external vent 12, preventing steam accumulation in localized areas. As the steam diffuses further outwards, the pressure gradually decreases, and the larger-diameter external vent 12 compensates for the increased steam flow by increasing the cross-sectional area. This structure, through dynamic matching of vent diameter and steam pressure, enables the steam to form a uniformly distributed laminar flow on the display panel, eliminating differences in steam coverage caused by pressure gradients.

[0027] If the display panel uses pores with uniform aperture, excessive steam will escape near steam outlet 5 due to excessive pressure, while the far area will form a steam blind zone due to insufficient pressure. This solution establishes a negative correlation between aperture and steam pressure to achieve adaptive adjustment of steam flow, thus solving the technical defect of uneven steam distribution. The double-layer flow distribution structure of the steam distribution trough 8 and the steam plate 11 forms a symmetrical steam distribution path, ensuring a balanced steam supply to all areas of the display panel.

[0028] Through the above technical solution, this application effectively balances the diffusion intensity of steam on the display board plane, ensuring that food placed anywhere on the display board receives equal amounts of steam heating. This avoids overcooking or undercooking in certain areas, ensuring that the food maintains a uniform level of doneness and appearance during the display process. In practical applications, a transparent display cover made of tempered glass and a metal frame can also be installed above the display stand 4 to cover the display board and the food placed on it.

[0029] Compared to existing technologies, traditional steamers lack display functionality due to their complete enclosure. This invention provides a display steamer platform that, through the construction of a top display stand 4, achieves visual display while maintaining steam heating. Steam is evenly distributed to the displayed food through external vents 12, preventing temperature drops or localized overheating caused by open exposure. Customers can directly observe the food's condition on the display stand 4, overcoming the technical obstacle of traditional steamers being unusable in open environments, while simultaneously ensuring the food's quality stability during the display process.

[0030] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
