Description

Technical Field

[0001] The utility model relates to the technical field of steam systems, in particular to a steam system of a bun steamer. Background Art

[0002] Steamed bun machines are a common food processing device, primarily used for steaming various types of pasta, such as baozi and steamed buns. They operate by heating water through a heating element, generating steam that is then transferred to a steamer chamber, where the food is cooked under high temperature and pressure. Their simple design makes them easy to operate; users simply add water, place the food, and set the timer. They are suitable for a variety of settings, including homes, tea restaurants, Western restaurants, beverage shops, and Chinese restaurants.

[0003] Currently, commercially available steamed bun machines, such as those found in convenience stores, use a boiler to generate steam. For example, a heating tube or plate heats water in the boiler, which then turns into steam. Once the steam enters the steamer, the food is heated by the high-temperature, high-pressure steam. The heat energy in the steam is transferred to the food, evenly heating it throughout the entire food, achieving the desired steaming effect.

[0004] After studying commercially available products, we found that there are still some shortcomings in the steamed bun machine. Due to the violent boiling of water in the boiler, the water flows into the steamed bun cavity through the nozzle on the top of the boiler. When the steam steams the food in the steamed bun cavity, the steam is sprayed directly onto the food, causing the surface of the food to be cooked too quickly while the inside is still hard, affecting the uniformity of food heating. At the same time, when the steam encounters the colder steamer or bun surface, it will condense into water droplets, causing the surface of the bun to be moist, bubbling, pitting or damaged, affecting the appearance and taste of the finished product.

[0005] Therefore, the present application aims to reduce the amount of steam sprayed toward the surface of food, which causes uneven heating of the food, while improving the integrity of the food's appearance and taste. Utility Model Content

[0006] The main purpose of the present invention is to provide a method for reducing the risk of steam being sprayed toward the surface of food, causing uneven heating of the food, while improving the integrity of the food's appearance and taste.

[0007] In order to achieve the above-mentioned object, the present invention provides a steaming system for a bun steamer, comprising a bun steaming cavity, and further comprising:

[0008] Liquid supply device;

[0009] a heating assembly, wherein the liquid inlet end of the heating assembly is connected to the liquid outlet end of the liquid supply device and heats the input liquid to generate steam, and the heating assembly is provided with one or more steam outlets at the connection end of the steamer cavity to introduce the steam into the steamer cavity; and

[0010] The steam nozzle is arranged at the steam outlet, and the steam spraying direction deviates from the heated part of the steamer cavity.

[0011] Furthermore, the spraying direction of the steam nozzle is flat spraying.

[0012] Furthermore, the angle between the steam jetting direction and the opening of the steamed bun cavity is 0-45°.

[0013] Furthermore, part of the steam outlets spray steam toward the door opening of the steamer cavity, and the angle between the steam outlets and the door opening of the steamer cavity is 0-15°.

[0014] Furthermore, the heating component adopts a steam generator, the water inlet end of the steam generator is connected to the liquid supply device, and the steam outlet end of the steam generator is connected to the steam nozzle.

[0015] Furthermore, a support is installed at one end of the steamer cavity close to the ground, a condensation seat with an opening toward the steamer cavity is also installed in the support, and a drainage piece is also installed at the condensed water outlet end of the condensation seat.

[0016] Furthermore, the steam nozzles are evenly installed on a side of the condensation seat facing the steamer cavity.

[0017] Furthermore, the liquid supply device includes a water storage component and a water pump, the water inlet of the water pump is connected to the water storage component through a pipeline, and the water outlet of the water pump is connected to the water inlet end of the heating component.

[0018] Furthermore, the water storage component includes a water tank, a solenoid valve provided at the water inlet end of the water tank, and a water level switch installed on the water tank.

[0019] The above technical solution has the following advantages:

[0020] The utility model adopts a method in which the steam outlet is offset from the heated component in the steamer cavity, and the spraying direction of the steam nozzle can be evenly arranged in the steamer cavity. The spraying method can fully fill the steamer cavity with steam, so that the outside of the food is heated more evenly, and it is avoided that the steam is sprayed onto the surface of the food, so that the sprayed surface of the food is easily cooked while the rest of the food is not cooked through, resulting in uneven heating and different taste of the food. At the same time, it also avoids the sprayed surface of the food from being easily damaged in the cooked state due to being cooked through too quickly, which affects the overall appearance.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not constitute a limitation to the present invention.

[0029] A steam system for a bun steamer includes a bun steaming cavity 10 and a support 30 installed at the bottom of the bun steaming cavity 10. The support 30 is used to support the bun steaming cavity 10. The support 30 includes an upper cover, a lower cover and a surrounding plate, so that the support 30 can enclose a cavity for a storage device. A heating component and a liquid supply device are provided in the cavity. The heating component can be an instant heating module block, and preferably a steam generator 501 is used to provide dry steam to reduce the moisture content of the steam flowing into the bun steaming cavity 10. One end of the liquid supply device pumps water, and the other end is connected to the water inlet end of the steam generator 501 to provide liquid to the steam generator 501, so that the liquid passing through the steam generator 501 evaporates to form steam. At this time, the evaporation temperature is 150℃-180℃, and the steam at this temperature flows into the steaming bun cavity 10 through a pipe, so that the dry steam steams the food in the steaming bun cavity 10, thereby reducing the moisture content of the steam in the steaming bun cavity 10, reducing the time required for steaming the buns, and also improving the taste of the steamed buns. The liquid supply device can adopt an electric pump or an air pump, preferably a water pump 505, which is used to pump in liquid and supply the liquid into the steam generator 501. The heated liquid adopts water, usually tap water, and salt water, spice water, broth, juice, wine, etc. can also be added, which can be added as needed.

[0030] like Figure 2and Figure 4 As shown, a water storage component 60 and a control circuit board 40 are also installed in the support 30. The water storage component 60 includes a water tank 601 and a solenoid valve 604 connected to the water inlet of the water tank 601. External pure water is connected to the solenoid valve 604 through a pipeline. When the power is turned on, the control circuit board 40 controls the entire system, the solenoid valve 604 opens, and water is added to the water tank 601. A water level switch 603 is provided on the water tank 601. When the water level reaches the upper limit, the water level switch 603 is triggered to close the water inlet. After a certain working cycle, the system prompts to perform a descaling program to clean the heating pipe through the control circuit board 40. At this time, the upper cover of the water tank 601 needs to be opened and the descaling agent is put into the water tank 601. Press the cleaning button on the control circuit board 40 and the system automatically cleans the pipe until the program ends. A pressure relief device is installed between the water pump 505 and the steam generator 501, preferably a pressure relief valve 506. When the pressure in the pipe exceeds 120Kpa, the pressure relief valve 506 opens to relieve the pressure, effectively protecting the entire pipeline system; the water tank 601 is also provided with a water quality monitor 602, which is used to monitor the water quality of the water tank 601. Specifically, TDS water quality testing can be used. A fixing seat 504 is installed around the steam generator 501, and the water pump 505 is installed on the fixing seat 504. The water pump 505 draws the liquid in the water tank 601 into the water inlet end of the steam generator 501.

[0031] like Figure 3 As shown, a temperature detector 502 and a temperature controller 503 are also installed on the steam generator 501. The temperature detector 502 can adopt NTC temperature detection to detect the temperature of the steam generator 501 and transmit the temperature signal to the control circuit board 40. The temperature controller 503 preferably adopts a jump type temperature controller to ensure the safety of the steam generator 501.

[0032] like Figure 2 and Figure 3 As shown, a condensation member 20 is also installed in the support 30, and the condensation member 20 includes a condensation seat 201 with an opening toward the steamer cavity 10 and a drainage member 202 connected to the condensation water outlet of the condensation seat 201. The condensed water in the steamer cavity 10 will flow from the opening of the condensation seat 201 to its inner wall, and slowly flow on its inner wall, and finally flow out from the drainage member 202. The inner wall of the condensation seat 201 can be set to be bowl-shaped, and the inner wall is provided with a stepped or spiral guide groove so that the condensed water can be hindered by the guide groove, that is, the condensed water flows along the spiral guide groove, or flows layer by layer along the stepped guide groove, so that the flow of the condensed water is blocked, thereby dissipating heat. The drainage member 202 can be connected to a pump body and a pipeline, which discharges the condensed water collected in the condensation seat 201.

[0033] like Figure 2-Figure 4As shown, the specific installation method is as follows: one or more steam nozzles 507 are installed on the condensation seat 201, and then fastened to the reserved holes of the upper cover, and a sealing structure is formed by a seal. The seal can be made of rubber. After completion, the upper cover and the enclosure are assembled to form a cavity; then the solenoid valve 604, water tank 601, water pump 505, steam generator 501, and pressure relief valve 506 are assembled in the cavity and connected through pipes. The drainage component 202 is connected to the condensation seat 201 through the drainage pipe, and the control circuit board 40 is also installed on the enclosure; finally, the upper and lower covers and the steamed bun cavity 10 are installed to form a whole.

[0034] like Figure 2 and Figure 5 As shown, a single steam nozzle 507 is used, and it is only necessary to ensure that the direction of the steam nozzle 507 is away from the door surface; the steam can be sprayed flatly from the steam outlet, or it can be sprayed obliquely in the direction of the support 30, but the spraying method needs to be adjusted accordingly to reduce the contact between the sprayed steam and the condensation seat 201, which not only reduces the heat loss, but also reduces the contact area between the steam and the condensed water, and avoids the condensed water from emitting wet steam due to the increase in temperature, that is, the steam temperature is insufficient and the water content is high, so that it can deviate from the heating element of the steamer cavity 10; in addition, it can also be tilted in the direction of the heating element, so that the steam rises from the side wall of the steamer cavity 10 and gradually wraps around the outside of the heating element. The heating element preferably refers to food, and tea sets and tableware can also be placed. The steam spray direction is the same as that of the steamer cavity 10. The angle of the opening surface of the steamer cavity 10 is an acute angle. Multiple steam nozzles 507 can be sprayed towards each other to reduce the steam impulse. Preferably, multiple spray directions are clockwise or counterclockwise to increase the steam flow rate in the steamer cavity 10 and accelerate the fluidity in the steamer cavity 10. Preferably, two steam nozzles 507 are installed on the circumferential surface of the condensation seat 201. In addition, they can also be evenly arranged at the bottom of the steamer cavity 10 in an equidistant manner, specifically symmetrically arranged on both sides of the bottom of the steamer cavity 10, and the spray directions of the steam nozzles 507 on both sides are relatively set to improve the uniformity of distribution; they can also be arranged in a vortex shape at the bottom of the steamer cavity 10, and the spray directions are all clockwise or counterclockwise, so as to drive the steam to rise evenly in the steamer cavity 10.

[0035] Among them, when two steam nozzles 507 are used, one of the steam nozzles 507 is inclined toward the door opening of the steam bun cavity 10, with a specific angle of 0-15 degrees, to ensure that the steam nozzle 507 does not directly spray steam toward the user at the door opening to avoid burns; the other steam nozzle 507 is opposite to the door opening of the steam bun cavity 10, with a specific angle of 0-45 degrees, so as to ensure that the two steam nozzles 507 spray steam in a circular shape in the steam bun cavity 10, and the steam rises evenly on the side of the steam bun cavity 10, so that the surface of the food is evenly contacted with the rising steam, ensuring that the food is heated evenly and will not be affected by the direct steam injection, thereby ensuring the integrity of the taste and appearance of the food. Figure 5 The direction of the arrow is the door opening direction; when multiple steam nozzles 507 are provided, the steam nozzle 507 can be deviated to the side close to the door opening surface of the steam bun cavity 10, and the specific deviation angle can be selected within the range of 0-15°. Specifically, the closer the steam nozzle 507 is to the door opening direction, the smaller the deviation angle is, so as to avoid the steam nozzle 507 from spraying directly at the user, and at the same time accelerate the annular flow of steam in the steam bun cavity 10.

[0036] like Figure 2-Figure 4 As shown, when the liquid supply device is operating, water pump 505 pumps water from water tank 601 and supplies water to steam generator 501. Steam generator 501 heats the liquid, vaporizing it into steam at 150°C-180°C. This steam is then delivered to steam bun cavity 10 through steam nozzle 507 for heating and baking. When the water level in water tank 601 reaches its lower limit, water level switch 603 is triggered, triggering solenoid valve 604 to replenish water in the water tank 601. This cycle continues. During this process, a TDS (Telescopic Determination of Water) test automatically checks water tank 601. If the TDS value exceeds 100, the system issues a warning, prompting the user to check the incoming water and determine if the filter cartridge needs replacement. If the TDS value exceeds a certain level, the system is forced to shut down, thus monitoring the water quality in water tank 601.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
