Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a drawer-type cooking device. Background Technology

[0002] Cooking appliances, such as electric ovens and microwave ovens, are equipped with a cooking cavity and a door assembly. After cooking, users open the door assembly and reach into the cooking cavity to remove the heated food. However, since the door assembly of existing cooking appliances is mostly located on the front and is hinged to the cooking cavity, users need to hold the food and move it horizontally a certain distance before reaching it out, which is inconvenient. In addition, if the temperature inside the cooking cavity is high, users may suffer burns when reaching into the cavity to remove food, affecting the user experience.

[0003] Drawer-type cooking appliances allow food to be pulled out of the cooking chamber along with the drawer, making it easy for users to take out the cooked food directly from the drawer. Due to their convenience, drawer-type cooking appliances have gradually begun to dominate the market.

[0004] However, the oven walls of existing drawer-type cooking appliances have a certain degree of thermal conductivity, causing some heat inside the oven cavity to be conducted to the outside. This leads to the following problems:

[0005] 1. As heat is transferred from the furnace cavity to the electrical cavity, the heat dissipation load of the electrical cavity will undoubtedly increase, which may easily lead to excessively high temperature inside the electrical cavity, or even cause high-temperature damage to electrical components.

[0006] 2. When cooking at extremely high temperatures (such as grilling), as some of the heat inside the oven cavity is conducted to the outside, the heating rate inside the oven cavity will slow down, and it may even be difficult to reach the required cooking temperature, affecting cooking efficiency and cooking results.

[0007] Therefore, this application is hereby submitted. Utility Model Content

[0008] In view of this, the present invention aims to propose a drawer-type cooking device to solve the problems in the prior art where heat in the oven cavity is conducted outward, resulting in increased heat dissipation load on the electrical cavity or slower heating rate in the oven cavity.

[0009] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0010] A drawer-type cooking device includes a drawer and a heat-insulating cavity assembly. The drawer is connected to the heat-insulating cavity assembly and is movable relative to the heat-insulating cavity assembly. The heat-insulating cavity assembly includes an inner cavity assembly and a heat-insulating frame assembly arranged sequentially from the inside to the outside. A heat-insulating element is disposed between the inner cavity assembly and the heat-insulating frame assembly. The heat-insulating element is detachably connected to the heat-insulating frame assembly, and the heat-insulating frame assembly is detachably connected to the inner cavity assembly.

[0011] Furthermore, the drawer-type cooking device includes a movable rail and a fixed rail. The movable rail is connected to the drawer, and the fixed rail is connected to the outer wall of the heat insulation rack assembly. The movable rail is connected to the fixed rail and can slide along the fixed rail.

[0012] Furthermore, at least a portion of the structure of the heat insulation frame assembly is connected to the inner cavity assembly by fasteners, and an assembly space is formed between the side of the heat insulation frame assembly facing the inner cavity assembly and the outer side wall of the inner cavity assembly, in which the heat insulation element is disposed.

[0013] Furthermore, a limiting piece is provided on the side of the heat insulation frame assembly facing the inner cavity assembly, and the heat insulation element is engaged with the limiting piece, and / or, the heat insulation frame assembly and the heat insulation element are connected by fasteners.

[0014] Furthermore, the drawer-type cooking device includes a heating component disposed between the inner cavity component and the heat insulation component.

[0015] Furthermore, an assembly plate is provided on the top of the left side wall and / or the top of the right side wall of the inner cavity assembly, and the heating assembly is detachably connected to the assembly plate.

[0016] Furthermore, the heating assembly includes a heater and an assembly cover, the assembly cover being connected to an assembly plate, an assembly cavity being formed between the assembly cover and the assembly plate, and the heater being disposed in the assembly cavity and connected to the assembly cover.

[0017] Furthermore, a heat insulation cover and a mounting cover are sequentially arranged on the outside of the assembly cover. The heat insulation cover covers the outside of the assembly cover, and the mounting cover covers the outside of the heat insulation cover. The assembly cover, the heat insulation cover, and the mounting cover are connected by fasteners.

[0018] Furthermore, the heat insulation component between the top plate of the inner cavity assembly and the top frame of the heat insulation frame assembly is referred to as the top heat insulation component, and the heating assembly is disposed between the top plate and the top heat insulation component.

[0019] Furthermore, the heat insulation component between the bottom plate of the inner cavity assembly and the bottom frame of the heat insulation frame assembly is referred to as the bottom heat insulation component, and the heating component is disposed between the bottom plate of the inner cavity assembly and the bottom heat insulation component.

[0020] Compared with the prior art, the drawer-type cooking device of this utility model has the following advantages:

[0021] The drawer-type cooking device described in this utility model has heat insulation components surrounding the outer wall of the entire inner cavity assembly, and is assembled and fixed by a heat insulation frame assembly to form a heat-insulated cavity assembly. Compared with the oven cavity of conventional cooking devices, this effectively prevents heat transfer from the oven cavity to the outside. On the one hand, it provides heat insulation and prevents heat transfer from the oven cavity to the electrical cavity of the cooking device, avoiding excessive heat load in the electrical cavity due to heat transfer, and even the possibility of excessive temperature in the electrical cavity and high-temperature damage to electrical components. On the other hand, it can effectively concentrate heat in the oven cavity, ensuring a good heating rate and reaching the required cooking temperature (such as the extremely high temperature cooking requirements under the grilling function) relatively quickly, which helps to improve cooking efficiency and ensure cooking results. Correspondingly, this application also reduces energy loss and waste caused by heat transfer from the oven cavity to the outside, and can effectively reduce power consumption under the same cooking conditions.

Detailed Implementation

[0033] The inventive concepts of this disclosure will be described below using terminology commonly used by those skilled in the art to convey the essence of their work to others skilled in the art. However, these inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments described herein.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Example 1

[0037] To address the problems in existing drawer-type cooking appliances where heat is conducted outwards from the oven cavity, leading to increased heat dissipation load on the electrical cavity or slower heating rate within the oven cavity, this embodiment proposes a drawer-type cooking appliance, as shown in the attached diagram. Figure 1-8 As shown, the drawer-type cooking device includes a drawer 101 and a heat-insulating cavity assembly 1. The drawer 101 is connected to the heat-insulating cavity assembly 1 and is movable relative to the heat-insulating cavity assembly 1. The heat-insulating cavity assembly 1 includes an inner cavity assembly 11 and a heat-insulating frame assembly 2 arranged sequentially from the inside to the outside. A heat-insulating element 20 is provided between the inner cavity assembly 11 and the heat-insulating frame assembly 2. The heat-insulating element 20 is detachably connected to the heat-insulating frame assembly 2, and the heat-insulating frame assembly 2 is detachably connected to the inner cavity assembly 11.

[0038] The inner cavity assembly 11 can have the same structure as the inner cavity of a conventional cooking device, including a top plate 111, a U-shaped main cavity 112, and a rear plate 114. The connection between the various plates, and whether they are integrated or separate, can be referenced from existing technologies and will not be elaborated further. Regarding the material of the heat insulation component 20, it can be conventional heat insulation cotton or other conventional heat insulation materials; this application does not impose specific limitations on it. In this application, heat insulation components 20 can be installed on the outer walls of the top plate 111, the outer side of the left side wall 1121 of the main cavity 112, the outer side of the bottom plate of the main cavity 112, the outer side of the right side wall 1122 of the main cavity 112, and the outer wall of the rear plate 114, and are assembled and fixed by the heat insulation frame assembly 2.

[0039] Therefore, this application surrounds the outer wall of the entire inner cavity assembly 11 with heat insulation element 20, and assembles and fixes it with heat insulation frame assembly 2 to form heat insulation cavity assembly 1. Compared with the oven cavity of conventional cooking equipment, this can effectively prevent the heat in the oven cavity from being transferred to the outside. On the one hand, it provides heat insulation and heat resistance, preventing the heat in the oven cavity from being transferred to the electrical cavity of the cooking equipment, and avoiding excessive heat dissipation load in the electrical cavity due to heat transfer, or even the situation of excessive temperature in the electrical cavity and high temperature damage to electrical components. On the other hand, it can effectively concentrate heat in the oven cavity, ensuring that the oven cavity has a good heating rate and can reach the cooking temperature (such as the extremely high temperature cooking requirements under the grilling function) relatively quickly, which helps to improve cooking efficiency and ensure cooking effect. Correspondingly, this application also reduces the energy loss and energy waste caused by heat transfer from the oven cavity to the outside, and can effectively reduce the consumption of electricity under the same cooking conditions.

[0040] At least a portion of the structure of the heat insulation frame assembly 2 is connected to the inner cavity assembly 11 via fasteners. An assembly space is formed between the side of the heat insulation frame assembly 2 facing the inner cavity assembly 11 and the outer wall of the inner cavity assembly 11. The heat insulation element 20 is disposed within this assembly space, thereby enabling a relatively secure assembly between the heat insulation frame assembly 2 and the inner cavity assembly 11, and also ensuring a relatively secure placement of the heat insulation element 20 between them. Since the heat insulation element 20 often possesses a certain degree of deformation capability, it is interference-fitted into the assembly space to further ensure its stable placement.

[0041] For the assembly of the heat insulation component 20, a limiting piece is provided on the side of the heat insulation frame assembly 2 facing the inner cavity assembly 11. The heat insulation component 20 is engaged with the limiting piece, and / or, the heat insulation frame assembly 2 and the heat insulation component 20 are connected by fasteners, thereby achieving a detachable connection between the heat insulation component 20 and the heat insulation frame assembly 2. The entire heat insulation frame assembly 2 includes at least one of the left side frame 22, base frame 23, right side frame 24, rear frame 25, and top frame 26. Any one of these frame structures can be connected to the inner cavity assembly 11 by fasteners and is also connected to the corresponding heat insulation component 20. Of course, any two adjacent frame structures can also be connected by fasteners.

[0042] Preferably, the heat insulation rack assembly 2 of this application includes a left side rack 22, a bottom rack 23, a right side rack 24, a rear rack 25, and a top rack 26, so that heat insulation components 20 are provided on all five sides of the cooking equipment except for the front side, so as to improve the heat insulation, heat resistance, and heat concentration effects.

[0043] The drawer-type cooking device includes a movable rail 1011 and a fixed rail 1012. The movable rail 1011 is connected to the drawer 101, and the fixed rail 1012 is connected to the outer wall of the heat insulation rack assembly 2. The movable rail 1011 is connected to the fixed rail 1012 and can slide along the fixed rail 1012, thereby allowing the drawer 101 to move relative to the heat insulation cavity assembly 1 without affecting the heat insulation of the heat insulation component 20 and the heat insulation rack assembly 2 on the inner cavity assembly 11.

[0044] In addition, the drawer-type cooking appliance also includes a front panel 107, which is connected to the front side of the inner cavity assembly 11. One end of the movable rail 1011 is connected to the drawer 101, and the other end can pass through the front panel 107 and be connected to the fixed rail 1012. Correspondingly, the heat insulation rack assembly 2 can also be connected to the front panel 107 to improve the assembly reliability between the heat insulation rack assembly 2 and the inner cavity assembly 11.

[0045] Correspondingly, the drawer-type cooking device also includes a shell structure, such as a top shell 102, a rear shell 103, a base 104, a left shell 105, and a right shell 106. Since the shell structure can be directly referred to the prior art, it will not be described in detail.

[0046] Example 2

[0047] This embodiment is a further introduction based on Embodiment 1, specifically addressing the problem that conventional cooking equipment has difficulty providing extremely high temperature cooking functions (such as grilling functions) or has poor extremely high temperature cooking effects.

[0048] The drawer-type cooking device includes a heating element 12, which is disposed between the inner cavity assembly 11 and the heat insulation member 20. Therefore, by placing the heating element 12 between the inner cavity assembly 11 and the heat insulation member 20, this embodiment enables the cooking device to provide higher cooking temperatures, achieving ultra-high temperature cooking. Furthermore, by heating the inner cavity assembly 11 and then conducting the heat to the oven cavity, the uniformity of temperature distribution within the oven cavity is improved, ensuring the ultra-high temperature cooking effect on food and preventing localized burning.

[0049] Regarding the configuration of the heating component 12, this embodiment proposes the following configuration methods.

[0050] Form 1

[0051] As attached Figure 1-5 As shown, an assembly plate 113 is provided on the top of the left side wall 1121 and / or the top of the right side wall 1122 of the main cavity 112. The heating assembly 12 is detachably connected to the assembly plate 113. Specifically, the heating assembly 12 includes a heater 121 and an assembly cover 122. The assembly cover 122 is snapped onto the assembly plate 113 and / or connected by fasteners, forming an assembly cavity between the assembly cover 122 and the assembly plate 113. The heater 121 is disposed in the assembly cavity and connected to the assembly cover 122. This facilitates the disassembly and maintenance of the heating assembly 12 and avoids direct contact with the heater 121. Furthermore, placing the heater 121 in a relatively enclosed assembly cavity, in addition to the heat insulation effect of the heat insulation frame assembly 2, the assembly cover 122 also provides a certain heat-concentrating and heat-insulating effect, forming an almost double-layer heat insulation structure, reducing heat conduction outward, and helping to further improve cooking efficiency and ensure cooking results. In addition, by connecting the heater 121 to the assembly cover 122, direct contact between the heater 121 and the inner cavity assembly 11 is avoided, thus preventing electric shock accidents to users caused by the heat insulation cavity assembly 1 being electrified.

[0052] Correspondingly, since the heating component 12 occupies a certain space, in order to avoid spatial interference with the heat insulation cavity component 1, the structure of the heat insulation cavity component 1 is also improved in this embodiment.

[0053] Specifically, a heat insulation cover 201 and a mounting cover 21 are sequentially arranged on the outer side of the assembly cover 122. The heat insulation cover 201 covers the outside of the assembly cover 122, and the mounting cover 21 covers the outside of the heat insulation cover 201. The assembly cover 122, the heat insulation cover 201, and the mounting cover 21 are connected by fasteners. Thus, by setting the heat insulation cover 201 and the mounting cover 21, which are adapted to the assembly cover 122, the heat insulation frame assembly 2 still maintains its enclosure and heat insulation of the heating component 12 and the inner cavity component 11, while avoiding spatial interference with the heating component 12, facilitating actual production assembly. It should be noted that the heat insulation cover 201 is a heat insulation component 20 installed on the heating component 12; it is simply named "heat insulation cover" for easier description. Correspondingly, the mounting cover 21 is part of the frame structure of the heat insulation frame assembly 2.

[0054] For the mounting cover 21, a first flange 211 is provided on the lower side of the mounting cover 21. The first flange 211 is connected to the left side frame 22 or the right side frame 24 of the heat insulation frame assembly 2, depending on whether the mounting cover 21 is located on the left or right side. The mounting cover 21 located on the left side of the inner cavity assembly 11 is connected to the left side frame 22, and the mounting cover 21 located on the right side of the inner cavity assembly 11 is connected to the right side frame 24. In addition, a second flange 212 is provided on the rear side of the mounting cover 21. The second flange 212 is connected to the rear plate 114 of the inner cavity assembly 11, thereby ensuring that the heat insulation structure and heat insulation frame structure at the heating assembly 12 have good assembly stability.

[0055] Form Two

[0056] As attached Figure 6-8 As shown, the heat insulation component 20 between the top plate 111 of the inner cavity assembly 11 and the top frame 26 of the heat insulation frame assembly 2 is referred to as the top heat insulation component 202, and the heating component 12 is disposed between the top plate 111 and the top heat insulation component 202.

[0057] The heating assembly 12 includes a first insulating sheet 123, a heating element 124, and a second insulating sheet 125 arranged sequentially from top to bottom. The heating element 124 can be a conventional heating wire, heating plate, etc. Thus, while ensuring the provision of heating function, the first insulating sheet 123 is placed between the top heat insulation component 202 and the heating element 124, and the second insulating sheet 125 is placed between the top plate 111 and the heating element 124, preventing the heat insulation cavity assembly 1 from becoming electrified and causing electric shock accidents to users.

[0058] Both the first insulating sheet 123 and the second insulating sheet 125 are preferably mica sheets, which have good insulation properties.

[0059] Form 3

[0060] The heat insulation component 20 between the bottom plate of the main cavity 112 and the bottom frame 23 of the heat insulation frame assembly 2 is referred to as the bottom heat insulation component, and the heating assembly 12 is disposed between the bottom plate of the main cavity 112 and the bottom heat insulation component.

[0061] The specific structure of the heating component 12 is the same as that of Form 2, except that its position is between the base plate and the bottom insulation component, which will not be described in detail.

[0062] This embodiment is not limited to the above three forms. Any one of the above three forms can be used, or any two or more can be used at the same time. Of course, other existing heating component settings in conventional cooking equipment can also be used.

[0063] Based on the heating component 12, a heat insulation structure is provided on the outer side of the heat insulation frame assembly 2 to further improve the heat insulation and heat resistance of the inner cavity assembly 11. The heat insulation structure can either surround and cover the entire outer wall of the heat insulation frame assembly 2, or it can be provided only on the side of the heat insulation frame assembly 2 corresponding to the heating component 12. For example, in Form 1, a heat insulation cover is provided outside the mounting cover 21; in Form 2, a heat insulation structure (upper heat insulation layer 27) is provided on the upper side of the top frame 26; and in Form 3, a heat insulation structure is provided on the lower side of the base frame 23.

[0064] The drawer-type cooking device described in this embodiment can be a microwave oven, an electric oven, an electric steamer, etc. Correspondingly, the drawer-type cooking device can also include conventional structures such as electronic control components and heat dissipation components. Since these conventional structures can be directly referred to in the prior art, they will not be described in detail.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
