Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to an energy-saving bun steaming machine. Background Art

[0002] Bun steamers are a common type of cooking equipment in modern food processing, widely used in the catering industry, supermarkets, and homes. Currently, water-based bun steamers on the market consist of two main components: a heating chamber and a steam chamber. The heating chamber is located below the steam chamber, housing a stainless steel barrel with a built-in heating pipe. This barrel is connected to an external water inlet pipe, which fills the barrel with water. Water is then heated by the heating pipe, generating steam that enters the steam chamber, where it is used to steam the food above, such as buns and steamed bread.

[0003] In actual use, the heating blocks of the bun steamer are usually in a continuous working state until the food is fully steamed. There are two major problems with the insulation function of the bun steamers currently on the market: First, when the bun steamer enters the insulation state after the food is steamed, it usually still keeps multiple heating blocks working, which consumes a lot of energy and affects the energy saving effect of the equipment. Second, some equipment will completely cut off the power and stop heating after the food is steamed. Although this avoids the waste of electricity, the lack of any heating support causes the temperature of the food to drop rapidly, affecting the user experience and food quality. In order to improve the energy efficiency of bun steamers, how to effectively reduce energy consumption while maintaining the temperature of the food has become an urgent problem to be solved.

[0004] Therefore, there is an urgent need in the prior art for a steamed bun machine design that can effectively keep food warm after steaming and save electricity during the heat preservation process, so as to solve the problems of high energy consumption or poor heat preservation effect of existing equipment. Utility Model Content

[0005] The purpose of the utility model is to provide an energy-saving bun steamer to solve the problems of high energy consumption or poor heat preservation effect of existing equipment mentioned in the background art.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] An energy-saving bun steamer comprises a base and a cabinet, wherein the cabinet has a chamber for placing food therein and at least partially extends into a water storage chamber in the base. The invention is characterized in that at least two heating elements are provided in the water storage chamber, and liquid water in the water storage chamber is evaporated by heat transfer from the heating elements. The water storage chamber is provided with a steam outlet, which is communicated with the chamber in the cabinet; the heating element is electrically connected to a control module, and the control module can control only one heating element to operate.

[0008] Preferably, a water storage box and an inner chassis are provided in the base, the inner chassis cover is provided on the water storage box to form the water storage chamber, and the steam outlet is located in the middle of the inner chassis.

[0009] Preferably, the water storage box has at least one isolation cover, and at least one heating element is located in the isolation cover. The upper end of the isolation cover cooperates with the inner bottom plate to form a steam channel, and a gap for liquid water to flow is left between the lower end of the isolation cover and the inner bottom surface of the water storage box.

[0010] And / or the lower end of the isolation cover has a first water hole or a first water gap for liquid water to flow;

[0011] And / or the isolation rib is provided with a second water hole or a second water gap for liquid water to flow.

[0012] Preferably, the upper end of the isolation cover extends through the inner chassis into the chamber, and the steam outlet is provided at the portion of the isolation cover extending above the inner chassis.

[0013] Preferably, the upper end of the isolation cover is open, the upper end of the isolation cover is clamped with the inner chassis, and the upper end of the isolation cover does not exceed the inner chassis. The upper surface of the inner chassis is covered with a steam cover, and the steam outlet is provided on the steam cover.

[0014] Preferably, the steam cover and the inner chassis are integrally formed.

[0015] Preferably, when a plurality of isolation covers are provided, the plurality of isolation covers are integrally formed.

[0016] Preferably, the steam outlet is located on the side of the portion of the isolation cover extending above the inner chassis, or the steam outlet is located on the side of the steam cover.

[0017] Preferably, the middle portion of the inner chassis is higher than the surrounding edges, and the edges of the inner chassis have first drainage holes.

[0018] Preferably, a recycled water box is provided at the lower part of the base to receive the recycled water discharged from the first drainage hole, or the first drainage hole is connected to the guide pipe to directly discharge the recycled water.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. Significant energy saving: Through the intelligent control module, the steamer only activates one heating element when keeping the food warm, rather than keeping multiple heating elements running simultaneously. This effectively reduces energy consumption, especially when keeping the food warm for a long time, and greatly improves the energy efficiency of the equipment.

[0021] 2. Better heat preservation effect: Different from the design of complete power off, this utility model maintains the temperature of food through the continuous supply of a small amount of steam, which not only avoids the rapid drop in food temperature, but also reduces the need for frequent reheating, ensuring that the food can still maintain good taste and quality during the heat preservation period.

[0022] 3. Improved User Experience: Users no longer have to worry about food cooling quickly after steaming, eliminating the pressure of rushing to eat. Furthermore, the energy-saving design allows users to conserve electricity during the heat preservation period, thereby reducing equipment operating costs.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Example 1

[0031] The invention discloses a steamed bun machine, which aims to improve the use efficiency of the steamed bun machine, reduce energy consumption and solve the problem of inconvenience in cleaning.

[0032] Combine Figure 1-4 As shown, the steamed bun machine includes a base 1 and a cabinet 2. The cabinet 2 is preferably a glass cabinet with a chamber inside for arranging shelves to place foods such as buns and steamed bread that need to be heated and steamed.

[0033] The base 1 includes an outer housing 11 that fits within the cabinet. A water storage box 12 is housed within the outer housing 11. An inner chassis 13 is located above the water storage box 12. The inner chassis 13 and the water storage box 12 cooperate to form a water storage chamber. In this embodiment, the water storage box 12 is completely contained within the outer housing 11. In another embodiment, the upper end of the water storage box 12 may extend upward and protrude beyond the outer housing 11 of the base 1.

[0034] A heating element 14 is located within the water storage chamber. Preferably, heating element 14 is a heating tube or a heating block. The upper end of heating element 14 is positioned within the water storage chamber, while the lower end extends downward from the water storage box 12 and is electrically connected to the control module. The connection between heating element 14 and water storage box 12 is sealed to ensure no water leaks during operation. The lower end of heating element 14 is also electrically connected to the control module, which intelligently controls the heating and heat preservation functions by adjusting the operating state of heating element 14. Heat transfer from heating element 14 evaporates the liquid water within the water storage chamber. A steam outlet 131 is located in the middle of the inner chassis 13, connecting the water storage chamber to the chamber within the cabinet 2. Those skilled in the art will appreciate that steam outlet 131, located in the middle of the inner chassis 13, allows steam generated in the water storage chamber to quickly enter the chamber within the cabinet 2, directly affecting the food. The steam outlet 131 is designed in the middle of the inner chassis 13 to ensure that the steam can be evenly diffused throughout the chamber, fully heating the food. At the same time, the central design also helps to prevent steam from accumulating at the edges and reduce the backflow of condensed water at the edges. By concentrating the position of the steam outlet 131, this design optimizes the flow path of the steam, thereby shortening the heating time, allowing the steam to act on the food more quickly, and improving the overall heating efficiency of the equipment. At the same time, the intelligent control module can adjust the operation of the heating element 14 in a timely manner according to the operating status of the steamed bun steamer, thereby effectively reducing energy consumption during the insulation stage.

[0035] At least two heating elements 14 are provided, and in this embodiment, three heating elements 14 are provided, distributed at different positions in the water storage chamber. The provision of multiple heating elements 14 can quickly heat the liquid water in the water storage chamber, generating sufficient steam to ensure that the food is heated quickly and evenly during the cooking process.

[0036] The control module is electrically connected to each heating element 14 and is capable of individually controlling the operating status of each heating element 14. The control module can utilize a traditional manual switch or an intelligent control system. The intelligent control module automatically adjusts the number and duration of heating elements 14 operating based on the steamer's usage phase. For example, during the steaming phase, the control module activates multiple heating elements 14 to ensure rapid steam generation and accelerate the cooking process. During the keep-warm phase, the control module may activate only one heating element 14 to reduce energy consumption while maintaining an appropriate temperature and preventing the food from cooling rapidly.

[0037] The steamer's intelligent control system allows it to flexibly adjust the operating status of the heating elements 14 at different stages. During the steaming phase, multiple heating elements 14 work together to quickly cook the food; during the warming phase, only one heating element 14 is active, significantly reducing power consumption and improving the device's energy efficiency. This flexible control not only saves energy but also prevents food from losing its flavor due to overheating.

[0038] The control module can be a separate switch, allowing the user to manually adjust the operating state of the heating element 14 according to needs, or an intelligent control module can be used to enable the device to automatically adjust the number and operating time of the heating elements 14 according to the state of the food. This automated control improves user convenience and optimizes the energy saving effect of the steamed bun machine.

[0039] The water storage box 12 has at least one isolation cover 15, each housing at least one heater 14. In this embodiment, three isolation covers 15 are provided, each housing a heater 14. The multiple isolation covers 15 are integrally formed. The upper end of the isolation cover 15 cooperates with the inner chassis 13 to form a steam passage, while a gap is left between the lower end of the isolation cover 15 and the inner bottom surface of the water storage box 12 for liquid water to flow.

[0040] The main function of the isolation cover 15 is to isolate a portion of the water around the heating element 14 from other liquid water in the water storage chamber. Each heating element 14 is only responsible for heating a small portion of the water in the isolation cover 15, and will not directly heat all the liquid water in the entire water storage chamber. This design effectively reduces the amount of water that needs to be heated, allowing the water to reach boiling point faster, thereby generating steam more quickly. This allows the steamer to generate steam faster during use, shorten heating time, and improve work efficiency. The water in the isolation cover 15 is continuously heated and evaporated into steam. As steam is generated, the water level in the isolation cover 15 will drop, and the water in the water storage chamber will gradually enter the isolation cover 15 through the water holes or gaps provided, replenishing new water. In this way, steam can be generated continuously to maintain a stable cooking environment.

[0041] Those skilled in the art will appreciate that the vent and the isolation cover 15 may also be staggered, and the steam may be directed through a steam channel provided at the bottom of the inner chassis 13 .

[0042] Specifically, in this embodiment, the upper end of the isolation cover 15 is open, and a vent is provided on the inner chassis 13. The upper end of the isolation cover 15 is clamped with the inner chassis 13 so that the vent is connected to the isolation cover 15. The upper end of the isolation cover 15 does not exceed the inner chassis 13. The upper surface of the inner chassis 13 is covered with a steam cover. The steam cover and the inner chassis 13 are integrally formed, and a steam outlet 131 is provided on the side of the steam cover.

[0043] The upper end of the isolation cover 15 may also extend through the inner chassis 13 into the chamber, and a steam outlet 131 is provided on the side of the portion of the isolation cover 15 extending above the inner chassis 13 .

[0044] Those skilled in the art should understand that the lower end of the isolation cover 15 has a first water hole or a first water gap for liquid water to flow, or the isolation rib is provided with a second water hole or a second water gap for liquid water to flow, which can replace the gap between the lower end of the isolation cover 15 and the inner bottom surface of the water storage box 12.

[0045] The middle of the inner chassis 13 is higher than the surrounding edges. The edge of the inner chassis 13 has a first drainage hole 133. The lower part of the base 1 is provided with a recycled water box 3 to receive the recycled water discharged from the first drainage hole 133, or the first drainage hole 133 is connected to the guide pipe 16 to directly discharge the recycled water.

[0046] Example 2

[0047] A steamed bun machine, combined with Figure 1-4 As shown, by designing multiple diversion grooves and drainage holes, the recycled water can be smoothly diverted to the recycled water box 3, making it easy to clean and drain, thereby improving the convenience and hygiene of the steamer. This recycled water structure has excellent drainage and recycling capabilities, effectively avoiding water accumulation and reducing maintenance difficulties.

[0048] Inner chassis 13 and drainage trough design: A first drainage trough 132 is provided around the upper edge of the inner chassis 13 to collect condensed water generated during the food cooking process. This design effectively concentrates the condensed water, preventing it from spilling onto other components. A first drain hole 133 is located at the bottom of the trough to ensure smooth drainage of the condensed water.

[0049] Drainage mechanism: The first drain hole 133 is located at the lowest point of the inner chassis 13, ensuring that condensed water can flow naturally to the drain hole, reducing water accumulation and improving drainage efficiency. This design avoids condensed water residue and further reduces cleaning workload.

[0050] Design of the water storage box 12: The top edge of the water storage box 12 is designed with an integral horizontal extension structure. This extension structure, through its unique height difference and guide groove design, helps guide and drain condensed water. The horizontal extension structure is equipped with a second guide groove 122 and a third guide groove 124. The bottom of the second guide groove 122 is equipped with a second drainage hole 123.

[0051] The first drainage hole 133 is designed to be located above the second guide groove 122, or correspondingly located above the second drainage hole 123. This coordinated design of the drainage holes allows condensed water to flow smoothly from the first guide groove 132 into the second guide groove 122 and then be discharged to the recovered water box 3, ensuring a smooth drainage path.

[0052] Specifically, the transverse extension structure consists of a first extension surface 1211 and a second extension surface 1212 of different relative heights, with the second extension surface 1212 being higher than the first extension surface 1211. This height difference provides a natural path for water flow and diversion. The outer edge of the first extension surface 1211 is provided with an upwardly bent annular connecting portion 1213, which connects to the second extension surface 1212 to ensure structural stability. The inner side of the first extension surface 1211 is provided with an upwardly extending annular ridge 1214, which cooperates with the annular connecting portion 1213 to form a second diversion groove 122 on the first extension surface 1211.

[0053] The second extension surface 1212 is further provided with a third diversion trough 124, which communicates with the second diversion trough 122. This trough 124 is primarily designed to collect condensed water from the glass cabinet. During operation of the steamed bun steamer, steam comes into contact with the cooler glass surface, generating condensed water. To prevent this condensed water from flowing into or out of the machine and potentially impacting it, the third diversion trough 124 is strategically designed to collect and divert this condensed water. The third diversion trough 124 is located below the glass cabinet, ensuring that condensed water from the glass cabinet flows naturally into the third diversion trough 124. The third diversion trough 124 communicates with the second diversion trough 122. After being collected by the third diversion trough 124, the condensed water flows smoothly into the second diversion trough 122 and is ultimately directed through the drainage holes into the water recovery box 3, preventing condensed water from accumulating on or within the machine. This diversion design allows for centralized treatment of condensed water, reducing water stains and accumulation during use of the steamed bun steamer, effectively improving the cleanliness and service life of the machine.

[0054] Design of the recycled water box 3: A pull-out water box is provided at the lower part of the base 1, below the water storage box 12, for receiving recycled water. The second drain hole 123 guides the recycled water into the recycled water box 3 through the guide tube 16. The recycled water box 3 is designed with a water inlet hole 31 on the upper end surface, which is opposite to the lower end of the guide tube 16 to ensure that water can enter the water box smoothly. The guide tube 16 is fixedly installed below the transverse extension structure, located on the outside of the water storage box 12, to ensure that the structure is stable and does not affect the installation and use of other components. Pull design and pouring port 33: A handle 32 is provided on the outer end of the recycled water box 3 to facilitate users to easily remove the water box. A pouring port 33 is designed on the top surface of the water box, located on the side corner close to the handle 32, so that users can easily pour out the recycled water when cleaning the water box, reducing the risk of spillage.

[0055] To ensure smooth drainage, the water storage box 12 and the inner chassis 13 are both tilted, with the tilt angle allowing condensed water to flow naturally toward the drain hole. Alternatively, the second guide groove 122 and the first guide groove 132 have a gradient depth structure, allowing the first drain hole 133 to be located at the lowest point of the inner chassis 13, while the second drain hole 123 is located at the lowest point of the transverse extension structure. This design optimizes the drainage path and prevents water accumulation.

[0056] Those skilled in the art should understand that the flow guide tube 16 can be an integral tubular structure, or can be formed by splicing or plugging a plurality of tubes.

[0057] This water recovery structure, through the coordinated operation of the diversion trough, drainage holes, diversion tube 16, and water recovery tray 3, solves the water recovery and cleaning issues of traditional bun steamers, particularly the accumulation of condensed water and poor drainage. Through a rationally angled design and diversion system, this structure effectively prevents condensed water from accumulating, preventing bacterial growth and odor generation, thereby improving the steamer's hygienic performance. Furthermore, the pull-out water tray simplifies cleaning, making it easy for users to maintain the equipment and further enhancing the steamer's user experience.

[0058] Example 3

[0059] Combine the heating structure of multiple heating elements in Example 1 and the condensed water recovery structure in Example 2.

[0060] Example 4

[0061] The difference between this embodiment and embodiment 2 is that the water recovery box and the water storage box are both located in the base, and the water recovery box is located on one side of the water storage box.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
