Description

TECHNICAL FIELD

[0001] The present application belongs to the field of pellet barbecue oven, and refers to a door handle structure of a pellet oven. BACKGROUND

[0002] The pellet oven is a heating device that burns pellets, mainly uses agricultural and forestry processing waste such as sawdust, straw, rice husk, tree bark and other biomass as raw materials, and through pretreatment and processing, the biomass is solidified into high-density pellet fuel, and then heated by burning. Since the biomass pellet fuel is a renewable resource, it does not contain sulfur and phosphorus, and does not produce sulfur dioxide and phosphorus pentoxide during combustion, which will not cause acid rain and air pollution. The CO2 emitted by biomass during combustion is as much as that absorbed during photosynthesis, so from the perspective of recycling, the net emission of CO2 to the air by biomass combustion is zero, effectively reducing the emission of atmospheric pollutants. The environmental protection monitoring emission detection is qualified, the thermal efficiency is high, the energy consumption is low, the energy is saved and the emission is reduced, and it is a new type of environmental protection energy product vigorously promoted by the government.

[0003] With the continuous innovation of pellet oven technology, pellet ovens are increasingly used in food making, mainly for baking food. The existing pellet oven is mainly used in the following way: the upper cover is opened to bake food. The locking and opening mode of the cover body is a combination of a handle and a buckle. Please refer to the technical solution disclosed in patent CN307954128S.

[0004] However, the above-mentioned pellet oven has some problems or can be improved: first, the simple structure of the pellet oven leads to single function, causing inconvenience in use. For example, when baking foods such as pizza that require high temperature, the upper cover needs to be closed to maintain high temperature. At this time, the food material needs to be put in by opening the upper cover, which is relatively laborious for the pellet oven, causing inconvenience to the user. Therefore, it is necessary to consider setting a labor-saving and flexible movable window structure. After setting the movable window structure, the handle operation of the cover body and the movable window needs to be simplified to set a handle to operate the opening and closing of the cover body and the movable window. In addition, the existing pellet oven generally uses a buckle structure to lock the cover body, which is not only not beautiful, but also very cumbersome to operate. Therefore, it is necessary to set a function-rich and convenient oven opening and closing structure, as well as a labor-saving and efficient locking structure and handle.

[0005] Therefore, the present application will provide a solution to the above technical problems. SUMMARY

[0006] The purpose of the present application is to provide a door handle structure of a pellet oven, which is provided with a more simplified and reasonable movable window locking structure, so that the function is more complete, a separate handle structure is provided to operate the opening and closing of the cover body and the movable window, which is labor-saving and convenient to use.

[0007] The objective of this invention is achieved as follows: a door handle structure for a pellet furnace includes a housing, a top cover, and a movable window. A handle is provided on the outer side wall of the movable window, and a locking element is provided on the inner side wall of the movable window. The handle is connected to the locking element and can drive the locking element to rotate. The locking element is integrally formed with a first locking part and a second locking part. The first locking part is located on the bottom side of the locking element, and the second locking part is located on the side of the locking element. During the rotation of the handle and the locking element, the locking state between the locking element and the housing and the top cover is changed.

[0008] In the aforementioned door handle structure of the pellet furnace, a connecting hole is provided in the middle of the locking member, and the handle drives the locking member to rotate through the connecting hole.

[0009] In the aforementioned door handle structure of the pellet furnace, the first locking part is in the shape of a long rod.

[0010] In the above-mentioned door handle structure of the pellet furnace, a locking block is provided at the bottom of the first locking part.

[0011] In the aforementioned pellet furnace door handle structure, the second locking part is in the form of a locking tooth.

[0012] In the above-mentioned door handle structure of the pellet furnace, a positioning grid is provided on the inner side of the handle, and a corresponding positioning element is provided on the locking element. The locking element locks the position of the handle by screwing the positioning element into the positioning grid.

[0013] In the aforementioned door handle structure of the pellet furnace, the positioning grid includes three spherical grids arranged in an arc.

[0014] In the aforementioned pellet furnace door handle structure, the locking member is provided with a receiving groove for accommodating the positioning member.

[0015] In the aforementioned door handle structure of the pellet furnace, the positioning element includes a spring and a steel ball, with the spring abutting against the steel ball within the positioning compartment.

[0016] In the above-mentioned door handle structure of the pellet furnace, the connecting hole forms a limiting facet, and the handle drives the locking element to rotate through the limiting facet.

[0036] The present invention will be further described below with reference to specific embodiments:

[0037] like Figures 1-11 As shown, a pellet furnace includes a shell 1, a top cover 2, and a pellet bin 3. The top cover 2 has a downwardly extending peripheral sidewall. The rear end of the top cover 2 is hinged to the shell 1. A crossbeam 23 is provided at the bottom of the front end of the top cover 2. A movable window 4 is hinged to the crossbeam 23. Torsion springs 24 are provided on both sides of the front end of the top cover 2. The movable window 4 is provided with a limiting groove 41 corresponding to the torsion spring 24. The torsion spring 24 assists the movable window 4 to open outward. A corresponding locking structure is provided between the movable window 4 and the peripheral sidewall of the top cover 2 and the upper edge of the shell 1. In this technical solution, the main part of the pellet furnace is formed by hinged connection of the shell 1 and the top cover 2. The top cover 2 has a downwardly extending sidewall aligned with the upper edge of the shell 1. A movable window 4 is provided on the front sidewall of the top cover 2. The movable window 4 is hinged to the crossbeam 23 at the bottom front end of the upper cover 2. The movable window 4 can be pulled outwards. When baking foods requiring high temperatures, such as pizza, the upper cover needs to be closed to maintain a high temperature, approximately 600°F. To add ingredients, the upper cover must be opened, which is inconvenient for the user due to the difficulty of opening and closing the upper cover of the pellet oven. Therefore, with the movable window structure, the user does not need to open the upper cover 2; they can simply push the movable window 4 in, making operation much easier. When the movable window 4 is opened, the torsion spring 24, located at both ends of the crossbeam 23, will propel the movable window 4 outwards through the abutment limiting groove 41. The operating principle of the torsion spring 24 can be found in the instruction manual. Figure 5 Included with instruction manual Figure 6 It is worth noting that the instruction manual includes... Figure 5 The torsion spring 24 in the picture shows the state after installation. (See instruction manual attached.) Figure 6 The torsion spring 24 is in a relaxed state and has not yet been engaged in the limiting groove 41.
