Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, and in particular to a baking oven. Background Technology

[0002] An oven is a device that uses heating elements to generate heat to bake food. The heat from an oven can be transferred to the surface and interior of the food through radiation, conduction, and convection, which allows the food to cook evenly. The high-temperature environment inside the oven can cause the Maillard reaction to occur rapidly on the surface of the food, forming a caramelized layer and preventing over-drying. The high-temperature environment of an oven is highly controllable, and a variety of types and flavors of food can be processed using an oven. Therefore, it has been widely used in both commercial and household applications.

[0003] Utensils used in oven food processing can be broadly categorized into two types: those that come into direct contact with the heat source and those that do not. Utensils that come into direct contact with the heat source include grill skewers, racks, and baking trays, while those that do not include plates, knives, forks, and chopsticks. Since oven utensils may come into contact with raw meat and may carry pathogens such as Salmonella or E. coli, direct contact with cooked food without sterilization can lead to cross-contamination. After prolonged use, food residue can easily accumulate in the crevices of the grill rack and baking tray, fostering mold growth and posing health risks. Therefore, utensils should be cleaned and sterilized before and after each use. Current technologies typically require separate sterilization equipment using methods such as boiling, steaming, or ultraviolet light, which are inconvenient and have low sterilization efficiency. Utility Model Content

The second end of the valve stem is located outside the furnace cavity and connected to the second valve plate. The elastic element is disposed between the second valve plate and the outer wall of the furnace body and always exerts an elastic force on the second valve plate towards the outside of the furnace cavity. The valve closes the first communication port through the elastic force of the elastic element to form a normally closed valve.

[0013] In one embodiment, the valve opening structure includes a pusher formed on the tableware sterilization container, the pusher being used to press against the second valve plate to open the valve when the tableware sterilization container is set in a preset position.

[0014] In one embodiment, a first guide portion is formed on the furnace body, and a second guide portion is formed on the tableware sterilization container. The first guide portion and the second guide portion cooperate to guide the tableware sterilization container to the preset position.

(See attached diagram.) Figures 1 to 2 An embodiment of the present invention provides an oven, comprising:

[0036] The furnace body 100 includes a heating source 110 and a furnace cavity 120. The heating source 110 is used to heat the furnace cavity 120. The furnace cavity 120 has a first communication port 121. A valve 130 is provided on the first communication port 121. The valve 130 is used to open or close the first communication port 121. The valve 130 is a normally closed valve 130.

[0037] The tableware sterilization container 200 has a second communication port 210 and includes a valve opening structure. The valve opening structure is used to open the valve 130 when the tableware sterilization container 200 is set in a preset position on the furnace body 100 so that the furnace cavity 120 and the inner cavity of the tableware sterilization container 200 are interconnected through the first communication port 121 and the second communication port 210.

[0038] The oven body 100 refers to the main structure of the oven, used to house or install the heating source 110, oven frame, controller, and other related components. The oven cavity 120 refers to the cavity inside the oven body 100, which can be used to place food to be processed. The heating source 110 refers to the component used to generate heat to heat the oven cavity 120, thereby achieving the baking of the food inside. It can be an electric heating component, a gas heating component, or an electromagnetic heating component, etc. The tableware sterilization container 200 refers to the container used to place tableware to be sterilized. The first connecting port 121 is opened on the wall of the oven cavity 120, and the second connecting port 210 is opened on the wall of the tableware sterilization container 200. The two are used to form a physical communication path between the oven cavity 120 and the tableware sterilization container 200. The first connecting port 121 and the second connecting port 210 can be set as regular-shaped openings such as circles or squares. Valve 130 refers to the control component installed on the first communication port 121, used to open or close the connection between the oven cavity 120 and the outside. Normally closed means that valve 130 is in the closed state by default, which reduces heat loss or gas leakage during oven operation. The valve opening structure refers to a mechanical, magnetic, or electronic device installed on the tableware sterilization container 200, such as a push rod, latch, microswitch, or infrared sensor. When the positional relationship between the tableware sterilization container 200 and the oven body 100 meets preset conditions, such as when the tableware sterilization container 200 is placed in a specific position on the oven body 100, it can mechanically press the valve 130, thereby opening the valve 130 and allowing heat, steam, or gas to enter the tableware sterilization container 200 from the oven cavity 120 to achieve the purpose of sterilizing the tableware inside the container.

[0039] The oven integrates tableware sterilization, eliminating the need for additional sterilization equipment, saving space and reducing energy consumption for separate sterilization. By placing the tableware sterilization container 200 in the preset position, valve 130 is opened via the valve opening mechanism. The oven generates hot air through a heat source, which flows through the oven cavity 120 into the tableware sterilization container 200, sterilizing the tableware inside at high temperature. This process requires no manual switching, reducing operational complexity. Valve 130 is normally closed, preventing the oven cavity 120 from connecting to the outside when no sterilization container is placed, thus ensuring the cooking performance of the oven cavity 120 and preventing contamination from external dust, maintaining the cleanliness of the oven cavity 120. The simple structure facilitates maintenance and improves the convenience and efficiency of tableware sterilization.

[0040] Figure 3 This is a schematic diagram illustrating the working principle of an oven valve when closed, according to an embodiment of the present invention. Figure 4 for Figure 3 A magnified view of a section at point A in the middle; Figure 5 This is a schematic diagram illustrating the working principle of an oven valve when it is opened, according to an embodiment of the present invention. Figure 6 for Figure 5 See the enlarged view of section A in the middle. Figure 1-6 In one exemplary embodiment, the valve 130 includes a first valve plate 131 and an elastic structure. One end of the elastic structure extends into the furnace cavity 120 and is connected to the first valve plate 131. The elastic structure can use elastic force to close the first communication port 121 through the first valve plate 131. The first valve plate 131 is located inside the furnace cavity 120, and the area of ​​the first valve plate 131 is larger than the area of ​​the first communication port 121, enabling the first valve plate 131 to close the first communication port 121. The elastic structure refers to the structure that controls the position of the first valve plate 131 through elastic force. When the tableware sterilization container 200 is not installed in place, the elastic structure is in its original state. It keeps the first valve plate 131 in close contact with the inner wall of the furnace cavity 120 through its own restoring force, ensuring that the first valve plate 131 can reliably close the first connecting port 121. When the tableware sterilization container 200 is installed in place, a force is applied to the elastic structure to overcome its own elastic force, so that there is a gap between the first valve plate 131 and the first connecting port 121, thereby enabling the valve 130 to be opened.

[0041] In an exemplary embodiment, the elastic structure includes a second valve plate 132, a valve stem 133, and an elastic element. The first valve plate 131 and the second valve plate 132 are respectively disposed at the first end and the second end of the valve stem 133. The first end of the valve stem 133 passes through the first communication port 121 and extends into the furnace cavity 120 to connect with the first valve plate 131. The second end of the valve stem 133 is located outside the furnace cavity 120 and connected to the second valve plate 132. The elastic element is disposed between the second valve plate 132 and the outer wall of the furnace body 100 and always exerts an elastic force on the second valve plate 132 toward the outside of the furnace cavity 120. The valve 130 closes the first communication port 121 under the elastic force of the elastic element through the first valve plate 131 to form a normally closed valve. The first valve plate 131, the second valve plate 132, and the valve stem 133 form a piston-type structure that can slide axially along the first communication port 121. This structure can transmit the thrust of the elastic element and the external triggering force. The elastic element is located between the second valve plate 132 and the outer wall of the furnace cavity 120. When the tableware sterilization container 200 is not installed, the elastic element can be in a compressed state. At this time, the restoring force of the elastic element itself causes the second valve plate 132 to tend to move away from the furnace body 100, thereby keeping the first valve plate 131 on the first communication port 121 and achieving the normal closure of the valve.

[0042] In an exemplary embodiment, the valve-opening structure includes a pusher portion 221 formed on the tableware sterilization container 200. The pusher portion 221 is used to press against the second valve plate 132 to open the valve 130 when the tableware sterilization container 200 is positioned in a preset position. The pusher portion 221 is a structure that can contact the second valve plate 132 and apply force to it when the tableware sterilization container 200 is positioned in the preset position. Under the gravity of the tableware sterilization container 200, the pusher portion 221 can act as a valve-opening structure to push the second valve plate 132, and can be a protruding or recessed structure. By providing the pusher portion 221, reliable opening of the valve 130 can be achieved.

[0043] In an exemplary embodiment, a first guide portion is formed on the furnace body 100, and a second guide portion is formed on the tableware sterilization container 200. The first guide portion and the second guide portion cooperate to guide the tableware sterilization container 200 to the preset position. The first and second guide portions restrict the movement direction of the tableware sterilization container 200 during placement, precisely guide it to the preset position, and ensure reliable contact between the push portion 221 and the valve 130. The first and second guide portions can be mating structures formed on the furnace body 100 and the tableware sterilization container 200, respectively, such as protrusions and guide grooves / holes, or may include components such as guide rails. When installing the tableware sterilization container 200, aligning the positions of the first and second guide portions achieves precise installation of the tableware sterilization container 200, reducing operational difficulty.

[0044] In an exemplary embodiment, the first guide portion includes a protrusion 122 formed on the upper wall of the furnace body, the protrusion 122 protruding from the upper wall of the furnace cavity 120 outwards. The second guide portion includes a recess 220 formed on the bottom surface of the tableware sterilization container 200, the recess 220 recessing from the bottom surface of the tableware sterilization container 200 inwards. When the tableware sterilization container 200 is placed in the preset position, the protrusion 122 is accommodated in the recess 220. The first communication port 121 is opened on the top surface of the protrusion 122, and the outer diameter of the protrusion 122 is greater than or equal to the outer diameter of the spring 134. The cooperation of the protrusion 122 and the recess 220 can easily achieve guidance between the tableware sterilization container 200 and the furnace body 100. The outer diameter of the protrusion 122 being greater than or equal to the outer diameter of the spring 134 can provide stable support for the spring 134 and improve the reliability of the valve 130.

[0045] In an exemplary embodiment, the elastic element is a spring 134 sleeved on the outside of the valve stem 133. The inner diameter of the spring 134 is smaller than the outer diameter of the second valve plate 132 and larger than the inner diameter of the first communication port 121. The valve stem 133 can restrict the movement path of the spring 134, allowing it to only compress or elongate axially and not easily bend. The inner diameter of the spring 134 is smaller than the outer diameter of the second valve plate 132, so that both ends of the spring 134 can directly abut against the second valve plate 132 and the outer wall of the furnace cavity 120, forming a stable and reliable axial support and preventing the spring 134 from falling off.

[0046] In an exemplary embodiment, the pushing part 221 is formed on the bottom surface of the recess 220, and the depth of the recess 220 is greater than the height of the protrusion 122. The pushing part 221, formed on the bottom surface of the recess 220, allows the tableware sterilization container 200 to be installed correctly during installation. Through the cooperation of the first guide part and the second guide part, not only can the tableware sterilization container 200 be installed in place, but the pushing part 221 can also be aligned with the second valve plate 132, reducing the difficulty of installation and positioning. The pushing part 221 can be located at the center of the bottom surface of the recess 220, or multiple pushing parts 221 can be symmetrically arranged on the bottom surface of the recess 220, so that the pushing part 221 can transmit a uniform vertical force to the first valve plate 131, preventing the valve stem 133 from tilting and affecting the opening degree of the valve 130. The depth of the recess 220 is greater than the height of the protrusion 122. This allows the protrusion 122 to be fully inserted into the recess 220, ensuring a tight fit between the bottom surface of the tableware sterilization container 200 and the oven surface. A sealing ring can be installed at the bottom of the container, and the vertical pressure after the two parts are inserted will compress the sealing ring, preventing steam leakage, improving airtightness, and thus enhancing sterilization efficiency. Furthermore, it ensures that the valve opening structure located in the recess 220 can contact the second valve plate 132, thereby opening the valve 130 and improving the reliability of the connection.

[0047] In one embodiment, the second communication port 210 is formed on the bottom wall and / or side wall of the recess, and the second valve plate 132 has a through hole 1321. The through hole on the second valve plate 132 can increase the cross-sectional area of ​​the airflow passage when the valve is open, making it easier for hot air to enter the tableware sterilization container 200. The second communication port 210 is formed on the bottom surface of the recess 220, which can shorten the flow path of airflow from the furnace chamber 120 to the tableware sterilization container 200 when the valve 130 is open, improve the tableware sterilization efficiency, and eliminate the need for additional piping.

[0048] In one embodiment, the pushing part 221 protrudes from the bottom wall of the recess 220 in the direction toward the second valve plate 132. When the pushing part 221 presses against the second valve plate 132, it can create a gas flow gap between the second valve plate 132 and the recess 220. By pressing the second valve plate 132 with the pushing part 221 and creating a gas flow gap between it and the recess 220, the position and size of the second connecting port 210 and the through hole 1321 can be flexibly set according to actual needs. During the production process, it is not necessary to precisely align the positions of the second connecting port 210 and the through hole 1321, which reduces the precision requirements for opening the hole and thus reduces the production difficulty.

[0049] In one exemplary embodiment, the spring 134 is fixedly connected to the second valve plate 132. The first end of the spring 134 is fixedly connected to the second valve plate 132, and the second end abuts against the furnace body 100. When no external force is applied, the spring 134 is in a naturally extended state. The elastic force of the spring 134 pushes the second valve plate 132 and drives the first valve plate 131 to close the first connecting port 121. When the valve opening structure is not activated, such as when the tableware sterilization container 200 is not placed in the preset position, the elastic force of the spring 134 can ensure that the valve 130 is tightly closed, preventing the leakage of high-temperature gas, fuel gas or steam in the furnace cavity 120 and avoiding safety hazards. When the valve opening structure pushes the valve plate to open, the spring 134 will be compressed and store elastic potential energy, opening the passage between the first connecting port 121 and the second connecting port 210. When the sterilization container is removed or deviates from the preset position, the elastic force of the spring 134 loses its external force and pulls back the valve plate to close the valve 130. By fixing the spring 134 and the second valve plate 132, the valve 130 can be automatically opened and closed by mechanical structure alone, without the need for electronic components, which is highly reliable and has a fast response speed.

[0050] In an exemplary embodiment, a plurality of second communication ports 210 are provided on the bottom surface of the recess 220. By providing a plurality of second communication ports 210 on the bottom surface of the recess 220, the cross-sectional area of ​​the airflow path between the tableware sterilization container 200 and the furnace body 100 can be increased, allowing heat to be transferred to the tableware sterilization container 200 more effectively and evenly, increasing the heating rate, and thus improving the efficiency of tableware sterilization.

[0051] In one exemplary embodiment, a temperature sensor is installed inside the tableware sterilization container 200, and the oven also includes a timer. The temperature sensor and the timer are electrically connected to the oven's controller. The temperature sensor can be a thermocouple, a resistance temperature detector (RTD), or a semiconductor thermistor, and can be installed on the inner wall or bottom of the tableware sterilization container 200 to ensure direct contact with the air and steam inside the container. The controller may include a microprocessor, input and output modules, and a power supply module. The controller acquires the temperature value inside the sterilization container based on the signal collected by the temperature sensor. When the temperature reaches a preset temperature, the timer starts timing. After the predetermined heating time has elapsed, the timer issues a prompt signal, and the controller can control the heating source 110 to stop heating based on this prompt signal.

[0052] In an exemplary embodiment, the heating source 110 is a gas heating source 110. The gas heating source 110 may include components such as a gas source, gas pipeline, valve 130, burner, and igniter. The gas heating source 110 has high heating efficiency, fast heating speed, and low operating cost. Using the gas heating source 110 as the heat source of the oven can not only improve cooking efficiency, but also improve the efficiency of tableware disinfection and reduce the cost and energy consumption of tableware disinfection.

[0053] In one exemplary embodiment, an oven is provided, including a tableware sterilization box, a heat flow piston valve, and a gas oven. When the tableware sterilization box is not placed, the heat flow piston valve, due to the elastic force of the compression spring 134, pulls the upper cover of the oven body 100 closed, and the heat flow is confined within the upper cover of the oven body 100. When the tableware sterilization box is placed, the heat flow piston valve, due to the compression spring 134 caused by the protrusion of the tableware sterilization box, pushes open the upper cover of the oven body 100 due to its own weight, allowing the heat flow to flow into the tableware sterilization box through the upper cover of the oven body 100, causing the temperature to rise. When the temperature rises to approximately 100 degrees Celsius, setting a timer to ignite for 15 minutes will effectively sterilize the tableware. This oven can sterilize tableware used during grilling, ensuring dining safety during grilling.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the 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.
