Description

Technical Field

[0001] This utility model relates to the field of heating element technology, specifically to a sleeve-type heating element and a cooking utensil. Background Technology

[0002] An air fryer is a machine that uses air to "fry" food. It mainly uses air to replace the hot oil in a frying pan to cook the food. At the same time, the hot air blows away the moisture on the surface of the food, giving the food an effect similar to deep-frying. Air fryers are generally equipped with heating elements that heat the air that comes in from the outside, thereby heating the food.

[0003] However, existing heating elements generally only have a single heating function, which means they can only be used to match a single type of appliance and cannot be used to match multiple appliances at the same time. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a sleeve-type heating element and a cooking appliance.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A sleeve-type heating tube includes a hollow heating outer tube and a heating inner tube inserted inside the heating outer tube. The heating inner tube and the heating outer tube have a certain gap and form a heating cavity.

[0007] The heating outer tube has an inlet end for water to enter and an outlet end for water to exit. The inlet end and the outlet end are connected to the heating chamber. Water is placed in along the inlet end and heated by the heating inner tube before being discharged from the outlet end.

[0008] Preferably, the inlet end is provided with an inlet pipe for input water, and the outlet end is provided with an outlet pipe for discharging heated water. Through these improvements, water is injected through the inlet pipe, entering the heating chamber between the inner and outer heating tubes. After being heated by the inner heating tube, the water is discharged through the outlet pipe, thus achieving water heating. This allows the entire heating element to heat not only the external space but also the water, enhancing the versatility of the heating element's functions.

[0009] Preferably, the outer diameter of the heating outer tube is greater than 10mm. These improvements not only ensure effective heating of the external space but also guarantee sufficient space within the internal heating chamber to heat a adequate amount of water.

[0010] Preferably, the length of the heating outer tube is 0.5-2m. These improvements not only increase the heating area to enhance the external heating effect, but also increase the space within the internal heating chamber, thereby increasing the amount of water heated at one time.

[0011] Preferably, the outlet end is connected to a reversing solenoid valve, and the reversing solenoid valve has an inlet connected to the outlet end and several outlets for discharging hot water. Through these improvements, by using the reversing solenoid valve to control the direction of hot water, hot water can be delivered to different structures, allowing the heating element to work with multiple structures simultaneously, achieving functional diversity.

[0012] Preferably, the heating outer tube is coiled, and a certain air passage gap is formed on the heating outer tube. Through these improvements, the overall heating area is increased, and air can move through the air passage gap, further improving heating efficiency.

[0013] A cooking appliance includes a main body with a cooking cavity for cooking food and a brewing cavity for brewing coffee. An outer heating tube is inserted into the cooking cavity, and a water outlet is connected to the brewing cavity. This improvement allows the inner heating tube to heat the outer heating tube, enabling the outer heating tube to heat the cooking cavity. Furthermore, the heating cavity can heat water for brewing coffee in the brewing cavity, making the appliance more versatile and enhancing the user experience.

[0014] Preferably, a cleaning nozzle is provided inside the main body, and the outlet of the reversing solenoid valve is connected to both the cleaning nozzle and the brewing chamber. Through these improvements, hot water can not only be used to brew coffee under the action of the reversing solenoid valve, but can also be injected into the cleaning nozzle to clean the entire surface of the heating element, improving the convenience of cleaning the heating element surface.

[0015] Preferably, a water supply tank is provided inside the main body, and the water supply tank is connected to the water inlet. With the above improvements, water from the water supply tank can be pumped into the heating element via a water pump, thereby achieving water delivery.

[0016] Preferably, a blower assembly is provided inside the cooking cavity, and the blower assembly is located above the heating outer tube. Through this improvement, the blower assembly draws in outside air and directs it through the heating outer tube. The heated air then circulates within the cooking cavity, achieving the baking of the food.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] By placing the inner heating tube inside the outer heating tube with a certain gap between them to form a heating chamber, water enters the heating chamber and is heated by the inner heating tube. In addition, as the inner heating tube heats up, the outer heating tube can also heat the external space. Thus, the entire heating tube not only has a heating function but also a water heating function, making the heating tube more versatile and allowing it to be matched with a variety of electrical appliances at the same time, thereby improving the user experience.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0025] like Figure 1-2 As shown, a sleeve-type heating tube includes a hollow heating outer tube 1 and a heating inner tube 2 inserted inside the heating outer tube 1. The heating inner tube 2 and the heating outer tube 1 have a certain gap and form a heating cavity 3.

[0026] Specifically, the heating outer tube 1 has an inlet end 4 for water to enter and an outlet end 5 for water to exit. The inlet end 4 and the outlet end 5 are connected to the heating chamber 3. Water is placed in along the inlet end 4 and heated by the heating inner tube 2 before being discharged from the outlet end 5.

[0027] By placing the inner heating tube 2 inside the outer heating tube 1 with a certain gap between them, a heating chamber 3 is formed. Water enters the heating chamber 3 and is heated by the inner heating tube 2. In addition, as the inner heating tube 2 heats up, the outer heating tube 1 can also heat the external space. Thus, the heating tube can be used to heat food or water, making its functions more versatile and allowing it to be matched with multiple electrical appliances at the same time, thereby improving the user experience.

[0028] like Figure 1-3 As shown in the further explanation of the implementation method in this embodiment, the water inlet end 4 is provided with a water inlet pipe 6 for input, and the water outlet end 5 is provided with a water outlet pipe 7 for discharging heated water. Water is injected into the water inlet pipe 6, so that the water enters the heating chamber 3 between the heating inner tube 2 and the heating outer tube 1. After being heated by the heating inner tube 2, the water is discharged from the water outlet pipe 7, thereby realizing the heating of water. This allows the entire heating tube to not only heat the external space, but also heat the water, thus improving the versatility of the heating tube's functions.

[0029] Furthermore, the outer diameter of the heating outer tube 1 is greater than 10mm, which not only ensures the heating effect on the external space, but also ensures the space inside the internal heating chamber 3, ensuring that a sufficient amount of water can be heated.

[0030] In addition, the length of the heating outer tube 1 is 0.5-2m, which not only increases the heating area to enhance the heating effect on the outside, but also increases the space inside the internal heating chamber 3, thereby increasing the amount of water heated at one time.

[0031] like Figure 3 As shown, in some other embodiments, the outlet 5 is connected to a reversing solenoid valve 8, and the reversing solenoid valve 8 has an inlet 9 connected to the outlet 5, and a plurality of outlets 10 for discharging hot water.

[0032] After the water is heated by the heating element, the hot water enters the reversing solenoid valve 8. The reversing solenoid valve 8 controls the direction of the hot water, which can be delivered to different structures. This allows the heating element to work with multiple structures simultaneously, achieving a variety of functions.

[0033] For example, the heating element 1 can be placed inside a cooking chamber for cooking, and the outlet 10 of the reversing solenoid valve 8 can be connected to a tea bar machine, coffee machine, or other structures, so that two different electrical appliances can be combined and the heating element can simultaneously serve as the heating structure for multiple electrical appliances.

[0034] Preferably, the heating outer tube 1 is coiled and has a certain air passage gap 11, which increases the overall heating area and the movement distance of water in the heating chamber 3, thereby improving the heating effect. In addition, when the heating tube heats the outside, the air can move through the air passage gap 11, thereby further improving the heating efficiency.

[0035] like Figures 1 to 3 As shown, as a further explanation of the implementation of the heating element in the cooking appliance of this application, the cooking appliance includes a main body 12, a cooking cavity 13 for cooking food and a brewing cavity 14 for brewing coffee are formed in the main body 12, the heating outer tube 1 is placed in the cooking cavity 13, and the water outlet 5 is connected to the brewing cavity 14.

[0036] During the use of the cooking appliance, the inner heating tube 2 can heat up inside the outer heating tube 1, thereby allowing the outer heating tube 1 to heat the food inside the cooking cavity 13. The heating cavity 3 can also heat water to brew coffee inside the brewing cavity 14, making the entire cooking appliance more versatile and enhancing the user experience.

[0037] Specifically, a water supply tank 16 is installed inside the main body 12. The water supply tank 16 is connected to the water inlet 4. Water can be pumped from the water supply tank 16 into the heating tube to achieve water delivery.

[0038] Furthermore, a blower assembly 17 is provided inside the cooking cavity 13, and the blower assembly 17 is located above the heating outer tube 1. The blower assembly 17 draws in external air and makes it pass through the heating outer tube 1. The heated air will circulate inside the cooking cavity 13 to bake the food.

[0039] Preferably, a cleaning nozzle 15 is provided inside the main body 12. The cleaning nozzle 15 is located above the heating element, and the outlet 10 of the reversing solenoid valve 8 is connected to the cleaning nozzle 15 and the brewing chamber 14 respectively. Hot water can not only be used to brew coffee under the action of the reversing solenoid valve 8, but also injected into the cleaning nozzle 15 to clean the entire surface of the heating element, improving the convenience of cleaning the surface of the heating element.

[0040] Hot water enters the cleaning nozzle 15, which sprays out high-temperature steam. The high-temperature steam acts on the heating element, thereby dissolving the oil stains on the heating element and cleaning it.

[0041] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
