Description
Technical Field
[0001] This utility model relates to the technical field of kitchen equipment, and in particular to a steamer structure and a breakfast cart with the steamer structure. Background Technology
[0002] Steamers, widely used cooking appliances in kitchens, work by heating a water tank to generate steam, which is then used to cook food inside. In the current market, gas-fired steamers hold a significant position due to their efficient energy supply; however, their water tank interior design still has certain limitations.
[0003] Existing steam cabinets generally use a flat-bottomed structure for the water tank inner liner, with a gas flame heating point located below the inner liner. When the gas flame is ignited, it acts directly on the bottom of the inner liner. Due to the large volume of the water tank, the gas flame needs to heat the entire tank, resulting in significant heat loss during the transfer process, making it impossible to achieve precise and efficient heating.
[0004] Furthermore, when existing steam cabinets are used in outdoor mobile scenarios, such as breakfast carts, the proportion of heat loss along the walls increases significantly compared to indoor use, resulting in a large amount of energy waste and making it difficult to meet the high-efficiency and energy-saving requirements of steam cabinets in modern mobile scenarios.
[0005] In view of this, the inventor has specifically designed a steamer structure and a breakfast cart with the steamer structure, which leads to this invention. Utility Model Content
[0006] To solve the above problems, one of the technical solutions of this utility model is as follows:
[0007] A steam cabinet structure includes a steam cabinet body, the steam cabinet body having a steam chamber with an upper opening, a heat collection area protruding towards the steam chamber formed at the bottom of the steam cabinet body, a plurality of heat pipes with internal cavities provided in the heat collection area, the cavities being connected to the steam chamber via the side wall of the heat collection area, and an insulation wall surrounding the outer periphery of the steam cabinet body.
[0008] Preferably, the heat pipes are at the same horizontal level and distributed in parallel.
[0009] Preferably, the heat pipe has at least two pipes.
[0010] Preferably, the heat pipe has at least one variable diameter region that extends outward.
[0011] Preferably, one end of a plurality of heat pipes is connected to the side wall of the heat collection area and the other end is connected to a heat collection plate. The heat collection plate is provided with a heat collection cavity, which is connected to the steam chamber through a cavity.
[0012] Preferably, the bottom edge of the insulation wall extends inward to form a folded edge that penetrates the gap between the insulation wall and the main body of the steamer.
[0013] Preferably, the main body of the steamer is square.
[0014] Preferably, the main body of the steamer is cylindrical.
[0015] Preferably, the bottom of the main body of the steamer is provided with a drain pipe that connects to the steaming chamber.
[0016] The second technical solution of this utility model is as follows:
[0017] A breakfast cart that includes a steamer structure.
[0018] The beneficial effects of this utility model are as follows:
[0019] The recessed heat collection area at the bottom of the main body of the steamer significantly increases the heating area of the steam chamber compared to the traditional flat-bottom structure. Combined with the internal heat pipes, it heats up rapidly through heat conduction. The water in the internal cavity is heated and then enters the steam chamber to provide auxiliary heating for the water inside the steam chamber. This forms a dual heating mode with the direct heating of the heat collection area, reducing heat transfer loss and greatly improving the heating efficiency of the steam chamber.
[0020] The insulation wall surrounding the main body of the steamer, combined with the folded edge extending inward from the bottom, forms a three-dimensional insulation structure that effectively retains the heat dissipated from the steam chamber wall. The folded edge also reduces heat loss from the bottom of the gap, thus minimizing energy waste.
[0021] The main body of the steamer can be designed as square or cylindrical. The square structure is suitable for rectangular steaming chambers, which facilitates the placement of multiple steaming racks and increases the amount of steaming per batch. The cylindrical structure optimizes heat flow distribution and is suitable for centralized heating scenarios and compact layouts of small equipment.
[0022] The bottom drain design makes cleaning easy.
[0023] In particular, when this steamer structure is applied to a breakfast cart, its efficient heating and excellent heat preservation performance enable rapid steaming of breakfast foods, shortening preheating time, reducing gas consumption, ensuring food insulation, and significantly improving the operational efficiency and user experience of the breakfast cart.
[0024] In summary, on the one hand, this utility model increases the heating area of the steam chamber by forming a concave heat collection area at the bottom of the main body of the steam cabinet. At the same time, it uses heat pipes to provide additional auxiliary heating for the water in the steam chamber, thereby improving the heating efficiency of the steam chamber. On the other hand, by wrapping an insulation wall around the outer periphery of the main body of the steam cabinet, the heat dissipated from the wall of the steam chamber is retained, and the heat from the wall is rapidly dissipated along the outer wall of the main body of the steam cabinet, thus achieving comprehensive optimization of the overall heating performance of the steam cabinet.

[0038] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, 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 only used to explain this utility model and are not intended to limit this utility model. Example 1
[0039] Please see Figures 1 to 5 This is a steamer structure, which is the preferred embodiment of the present utility model. It includes a steamer body 100, and the steamer body 100 has a steaming chamber 110 with an upper opening.
[0040] In this embodiment, the main body 100 of the steamer is square, and the steaming chamber 110 is a square inner cavity formed by a downward indentation along the upper side of the main body 100 of the steamer. The opening of the steaming chamber 110 is also provided with a step edge 120, and the corresponding steaming tray, lid, etc. can be installed on the upper part of the steaming chamber 110 using the step edge 120.
[0041] Specifically, such as Figure 2 , 3 As shown in Figure 4, the bottom of the main body 100 of the steamer forms a heat collection area 200 that protrudes towards the steam chamber 110.
[0042] In this embodiment, the heat collection area 200 is square in shape similar to the steam chamber 110, and is formed by four side walls 210 integrally formed on the vertical upper edge of the bottom of the steam cabinet body 100 and a top wall 220 covering the top of the four side walls 210. An opening is formed at the bottom of the heat collection area 200 so that heating points can be arranged below the heat collection area 200, and the bottom of the steam cabinet body 100 and the heat collection area 200 can be heated by an external heat source.
[0043] like Figure 2 , 4 As shown, the heat collection zone 200 is provided with several heat pipes 300 with cavities 310 inside, and the cavities 310 are connected to the steam chamber 110 through the side wall 210 of the heat collection zone 200.
[0044] In this embodiment, the heat pipe 300 is a circular pipe integrally welded between the two opposite side walls 210 of the heat collection area 200. The inner side of the heat pipe 300 has a cavity 310 for water flow. Flow holes 211 opposite to the cavity 310 are opened through the two opposite side walls 210 to realize the communication between the cavity 310 and the steam chamber 110.
[0045] By adding a heat pipe 300, water in the steam chamber 110 can be introduced for synchronous heating. The water in the internal cavity 310 is heated rapidly through heat conduction and then transferred into the steam chamber 110, thus achieving auxiliary heating of the water in the steam chamber 110. This forms a dual heating mode with the direct heating of the heat collection area 200, reducing heat transfer loss and significantly improving the heating efficiency of the steam chamber 110.
[0046] like Figure 2 , 4As shown in Figure 5, in order to enhance the heating effect, at least two heat pipes 300 are provided. In this embodiment, four heat pipes 300 are provided, and they are arranged side by side in parallel with each other. The four heat pipes 300 are at the same horizontal height.
[0047] like Figure 2 , 4 As shown in Figure 5, the main body 100 of the steamer is surrounded by an insulation wall 400.
[0048] In this embodiment, the insulation wall 400 is integrally formed with the main body 100 of the steamer. The four edges of the upper end of the main body 100 of the steamer extend vertically downward to form four insulation boards 410. The edges of adjacent insulation boards 410 are welded and fixed to form an integral whole. Finally, a square sleeve-shaped structure with an opening at the bottom is formed on the outer periphery of the main body 100 of the steamer, which completely covers the main body of the main body 100 of the steamer.
[0049] Specifically, the lower edge of the insulation wall 400 extends to a position flush with the lowest point of the lower end face of the steamer body 100, or may extend further to a position lower than the lower end face of the steamer body 100, thereby forming a good covering of the steamer body 100 and maintaining a certain insulation effect.
[0050] At this time, a certain gap 420 is formed between the main body 100 of the steamer and the insulation wall 400. Although the hot air carrying heat is blocked by the insulation wall 400, some of it can still overflow along the opening on the lower side of the gap 420, causing a certain amount of heat loss. Therefore, the bottom edge of the insulation wall 400 extends inward to form a folded edge 430 that invades the gap 420 between the insulation wall 400 and the main body 100 of the steamer.
[0051] In this embodiment, the folded edge 430 is formed by vertically bending the bottom of the insulation board 410. Adjacent folded edges 430 are connected and fixed by a 45° cut edge 431, thereby forming a ring at the bottom opening of the insulation wall 400 to block the gap 420, thereby reducing the blocking structure of the opening below the gap 420, thus blocking the hot air escaping along the opening to a certain extent, and further improving the heat retention rate.
[0052] like Figure 2 , 3As shown in Figure 4, the bottom of the steam cabinet body 100 is provided with a drain pipe 500 that connects to the steam chamber 110. In this embodiment, the heat collection area 200 is designed at the center of the inner bottom of the steam cabinet body 100. Therefore, a rectangular bottom area is reserved around the periphery of the heat collection area 200. This bottom area serves as the bottom surface of the steam chamber 110, and the drain pipe 500 is connected to it. The water flow is controlled by a ball valve 520 and other control components on the drain pipe 500. The ball valve 520 and the drain pipe 500 are connected and fixed by an external thread 510 reserved on the outer periphery of the bottom of the drain pipe 500. This facilitates the convenient drainage of residual water in the steam cabinet when cleaning or water changing is required.
[0053] Specifically, in this embodiment, the main body 100 of the steam cabinet, the heat collection area 200, the heat pipe 300, the insulation wall 400, and the folded edge 430 are all made of stainless steel plates, and the overall shape of the steam cabinet structure is formed by bending, welding and other operations. Example 2
[0054] Please see Figure 6 This is a steamer structure as an embodiment 2 of the present invention. The difference from embodiment 1 is that the heat pipe 300 has at least one variable diameter region that extends outward.
[0055] Specifically, in this embodiment, the heat pipe 300 is a variable diameter pipe, with an outwardly expanding diameter section 320 (i.e., variable diameter region) formed in its middle, and the expansion section 320 and the two ends of the heat pipe 300 are smoothly transitioned.
[0056] Thus, by increasing the heating area of the heat pipe 300 through the enlarged diameter section 320, the heating efficiency of the water by the external heat source is further improved. Example 3
[0057] Please see Figure 7 This is a steamer structure as embodiment 3 of the present utility model. The difference from embodiment 1 is that the main body 100 of the steamer is cylindrical.
[0058] In this embodiment, the main body 100 of the steamer is cylindrical in shape, the shape of the steaming chamber 110 is similar to that of the main body 100 of the steamer and is also cylindrical, the heat collection area 200 is a corresponding cylindrical concave structure, and the heat pipes 300 are arranged in parallel between the inner ring walls of the heat collection area 200 (not shown in the figure).
[0059] In this embodiment, the heat collection area 200 comprises an inner ring wall formed by bending a stainless steel plate and connecting its ends to form an annular shape, and a top wall 220 covering the top of the inner ring wall (not shown in the figure).
[0060] In this embodiment, the insulation wall 400 is composed of annular wall surfaces distributed around the circumference of the main body 100 of the steamer, and the folded edge 430 is correspondingly annular in shape.
[0061] Therefore, the main body of the steamer 100 can be designed as square or cylindrical. The square structure is compatible with the rectangular steaming chamber 110, which facilitates the placement of multiple steaming racks and increases the amount of steaming per batch. The cylindrical structure optimizes the heat flow distribution and is suitable for centralized heating scenarios and compact layouts of small equipment. Example 4
[0062] Please see Figure 8 This is a steamer structure as embodiment 4 of the present utility model. The difference from embodiment 3 is that the heat pipe 300 is a variable diameter pipe, and an outwardly expanding section 320 is formed in the middle of it. The expansion section 320 and the two ends of the heat pipe 300 are smoothly transitioned. Example 5
[0063] Please see Figure 9 This is a steam cabinet structure as embodiment 5 of the present utility model. The difference from embodiment 3 is that one end of several heat pipes 300 is connected to the side wall 210 of the heat collection area 200 and the other end is connected to a heat collection plate 600. A heat collection cavity (not shown in the figure) is provided in the heat collection plate 600. The heat collection cavity is connected to the steaming chamber 110 through the cavity 310.
[0064] Furthermore, the above structure can also be directly applied to the square-shaped steamer body 100, without any restrictions. Example 6
[0065] A breakfast cart comprising a steamer structure as shown in Example 1.
[0066] In this embodiment, the breakfast cart includes at least a cart body, a steamer structure, and an external heat source. An opening for installing the steamer structure is cut into the cart body. An external heat source, such as a portable gas stove (preferably a split portable gas stove) (not shown in the figure), is arranged below the heat collection area 200 of the steamer structure, so that the steamer structure can adapt to the steaming and cooking work in a mobile scenario.
[0067] The beneficial effects of this utility model are as follows:
[0068] In summary, on the one hand, this utility model increases the heating area of the steam chamber 110 by forming a concave heat collection area 200 at the bottom of the steam cabinet body 100. At the same time, it uses heat pipes 300 to provide additional auxiliary heating for the water in the steam chamber 110, thereby improving the heating efficiency of the steam chamber 110. On the other hand, by wrapping an insulation wall 400 around the outer periphery of the steam cabinet body 100, the heat dissipated from the wall of the steam chamber 110 is retained, and the heat from the wall is rapidly dissipated along the outer wall of the steam cabinet body 100, thus achieving comprehensive optimization of the overall heating performance of the steam cabinet.
[0069] In particular, when this steamer structure is applied to a breakfast cart, its efficient heating and excellent heat preservation performance enable rapid steaming of breakfast foods, shortening preheating time, reducing gas consumption, ensuring food insulation, and significantly improving the operational efficiency and user experience of the breakfast cart.
[0070] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
