Description

Technical Field

[0001] This utility model relates to the field of electric oven technology, and in particular to an oven with independent temperature control in different zones. Background Technology

[0002] An oven is a sealed appliance used for baking food or drying products. It is divided into household ovens and industrial ovens. Household ovens can be used to process some pasta. Industrial ovens are equipment used in industry to dry products; they can be electric or gas-fired and are also called baking ovens or drying boxes. Electric ovens use the radiant heat emitted by electric heating elements to bake food. They can be used to make roast chicken, roast duck, bake bread, pastries, etc. Depending on the needs of the food being baked, the temperature of an electric oven can generally be adjusted within the range of 50-250℃.

[0003] Some existing ovens typically feature an integrated oven chamber for baking food. However, integrated oven chambers have higher power consumption, resulting in higher energy consumption when baking a small number of foods, which is wasteful of energy. Furthermore, integrated oven chambers are not convenient for baking different foods at different temperatures, making them inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing ovens, which are usually set up with an integrated oven chamber for baking food. However, the integrated oven chamber has a large power consumption, and when there are few foods to be baked, the energy consumption of the integrated oven chamber is high, which is wasteful of energy. In addition, the integrated oven chamber is not convenient for baking different foods at different temperatures, and is not convenient to use. The invention provides an oven with independent temperature control in different zones.

[0005] The purpose of this utility model is achieved through the following technical solution: an oven with independent temperature control in partitions, including an outer shell, a furnace chamber inside the outer shell, three sets of baking chambers arranged at equal distances inside the furnace chamber, a baking tray installed at the bottom of each set of baking chambers, and heating tubes installed at the top and bottom of each set of baking chambers, with the bottom and top of two adjacent sets of baking chambers sharing the same set of heating tubes.

[0006] The outer casing is equipped with four controllers, each corresponding to a heating element. These controllers regulate the temperature of the heating elements. Each baking chamber is equipped with a temperature sensor, which is electrically connected to the controllers corresponding to the two heating elements within its chamber. By configuring the baking trays and two heating elements within each chamber, each baking chamber in the oven has independent temperature control capabilities. When temperature control is needed for one of the baking chambers, the controller corresponding to the two baking trays in that chamber is rotated to adjust the desired baking temperature. When the temperature sensor in the baking chamber detects that the temperature inside is lower than the set temperature, it controls the corresponding controller to activate the heating element for heating. This allows for independent temperature control of the baking chambers within the oven, enabling the use of only the heating elements in the corresponding baking chamber when baking a small quantity of food, effectively saving energy. Furthermore, the three baking chambers allow for baking foods at different temperatures on the top and bottom layers, improving the equipment's versatility.

[0007] A further technical solution is to place the heating element at the bottom of each baking chamber below the baking tray. This placement of the heating element at the bottom of the baking chamber facilitates heat conduction to the baking tray and improves the heating effect at the bottom of the baking chamber.

[0008] A further technical solution is to install lighting inside the baking chamber, and to install opening and closing doors on the outer shell corresponding to the oven chamber. Each opening and closing door is equipped with three sets of transparent observation windows, each corresponding to one of the three baking chambers. The transparent observation windows facilitate observation of the baking process of the food in the corresponding baking chamber.

[0009] A further technical solution is to install an exhaust vent corresponding to the oven chamber on the upper part of the door. By opening the exhaust vent, the moisture generated during baking can be discharged, preventing the moisture from affecting the baking effect of the food and also preventing the moisture from damaging the electrical components inside the oven chamber.

[0010] A further technical solution is to install sealing gaskets on the outside of the baking chamber that correspond to the opening and closing doors. The installation of sealing gaskets improves the sealing effect between the oven chamber and the opening and closing doors, thus preventing heat loss.

[0011] A further technical solution is to install a bracket at the bottom of the outer casing, install a tray shelf on the bracket, and install a baffle corresponding to the tray shelf on the back of the bracket. By setting up the tray shelf, it is convenient to store food trays and improve the convenience of operation, and the baffle limits the movement of the food trays.

[0012] A further technical solution is to install universal self-locking wheels at the bottom of the bracket. These universal self-locking wheels enable the equipment to move, improving ease of use.

[0013] A further technical solution is that the baking tray includes a stainless steel support and an iolite slab. The iolite slab is placed on the upper part of the stainless steel support. The iolite slab has good thermal conductivity, as well as good heat resistance and heat retention, which can make the baked food more natural in flavor and richer in taste, and preserve the natural flavor of the food to the greatest extent.

[0014] A further technical solution is to install indicator lights on the outer casing that correspond to the controller. These indicator lights illuminate when the controller controls the heating element to heat, making it easier to observe the working status of the controller and the heating element.

[0015] A further technical solution is to design the heating element in an arc shape. This arc shape allows the heating element to have good heat dissipation, resulting in more even heat distribution within the baking chamber and improved baking performance.

[0016] This invention has the following advantages: By setting a baking tray and two sets of heating tubes in the baking chamber, each baking chamber in the furnace has the ability to independently control the temperature. When baking a small amount of food, only the heating tube in the corresponding baking chamber needs to be activated, which effectively saves energy. At the same time, setting three sets of baking chambers can bake food at different temperatures at the top and bottom, improving the applicability of the equipment. Attached Figure Description

[0028] like Figures 1-3As shown, an oven with independent temperature control in each zone includes an outer shell 1, a furnace chamber inside the outer shell 1, and three sets of baking chambers 3 arranged at equal intervals inside the furnace chamber. Each set of baking chambers 3 has a baking tray 2 installed at the bottom, and heating tubes 4 installed at the top and bottom of each set of baking chambers 3. The bottom and top of two adjacent sets of baking chambers 3 share the same set of heating tubes 4. For example, the bottom heating tube of a baking chamber is also the top heating tube of the baking chamber below it. The heating tubes 4 are tubular electric heating elements.

[0029] Four controllers 6, each corresponding to a heating element 4, are installed on the outer casing 1. The controllers 6 are responsible for regulating the temperature of the heating elements 4. Each baking chamber 3 is equipped with a temperature sensor 5, which is electrically connected to the controllers 6 corresponding to the two heating elements 4 in its respective baking chamber 3. By setting the baking trays 2 and the two heating elements 4 in the baking chamber 3, each baking chamber 3 in the oven has the ability to independently control the temperature. When it is necessary to control the temperature of one of the baking chambers 3, the controllers 6 corresponding to the two baking trays 2 in that baking chamber 3 are rotated to adjust to the required baking temperature. When the temperature sensor 5 in the baking chamber 3 detects that the temperature in the baking chamber 3 is lower than the set temperature, the corresponding controller 6 is controlled to start the heating element 4 for heating. This allows the baking chambers 3 in the oven to have independent temperature control capabilities. When baking a small amount of food, only the heating element 4 in the corresponding baking chamber 3 needs to be activated, effectively saving energy. At the same time, setting up three baking chambers 3 allows for baking food at different temperatures at the top and bottom, improving the applicability of the equipment.

[0030] The heating pipe 4 at the bottom of each baking chamber 3 is located below the baking tray 2. Setting the heating pipe 4 at the bottom of the baking chamber 3 can facilitate heat conduction to the baking tray 2 and improve the heating effect at the bottom of the baking chamber 3. The outer shell 1 is equipped with insulation cotton 17 corresponding to the furnace chamber.

[0031] The baking chamber 3 is equipped with a light 9, and the outer shell 1 is equipped with an opening and closing door 8 corresponding to the furnace. The opening and closing door 8 is equipped with three sets of transparent observation windows 10 corresponding to the three baking chambers 3 respectively. The transparent observation windows 10 are set to facilitate the observation of the baking status of the food in the corresponding baking chamber 3.

[0032] The upper part of the opening and closing door 8 is equipped with an exhaust port 11 corresponding to the oven chamber. By opening the exhaust port 11, the water vapor generated during baking can be discharged, preventing the water vapor from affecting the baking effect of the food and also preventing the water vapor from damaging the electrical components inside the oven chamber.

[0033] The baking chamber 3 is equipped with a sealing gasket 12 corresponding to the opening and closing door 8. The sealing gasket 12 improves the sealing effect between the oven chamber and the opening and closing door 8 and avoids heat loss. The sealing gasket 12 can also be replaced with an oven sealing rope.

[0034] A bracket 13 is installed at the bottom of the outer casing 1, and a tray plate 14 is installed on the bracket 13. A baffle 15 corresponding to the tray plate 14 is installed on the back of the bracket 13. By setting the tray plate 14, it is convenient to store food trays and improve the convenience of operation. The baffle 15 limits the food tray.

[0035] The bottom of the bracket 13 is equipped with universal self-locking wheels 16. The universal self-locking wheels 16 enable the equipment to move and improve the ease of use.

[0036] Baking tray 2 includes a stainless steel support and an iolite slab. The iolite slab is placed on top of the stainless steel support. The iolite slab has good heat conduction properties, as well as good heat resistance and heat retention, which can make the baked food more natural in flavor and richer in taste, and preserve the natural flavor of the food to the greatest extent.

[0037] An indicator light 7 corresponding to the controller 6 is installed on the outer casing 1. The indicator light 7 can light up when the controller 6 controls the heating tube 4 to heat. The indicator light 7 is set up to facilitate observation of the working status of the controller 6 and the heating tube 4.

[0038] The heating element 4 is arranged in an arc shape, which enables the heating element 4 to have a good heat dissipation effect, thereby making the heat distribution in the baking chamber 3 uniform and improving the baking effect.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
