Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a door handle, a door body component and a cooking device. Background Art

[0002] Many cooking devices such as ovens and steamers include a cooking chamber, in which a heating unit is arranged, which can generate a large amount of heat in the cooking chamber, so that the food in the cooking chamber is cooked. Ideally, the cooking device's cabinet and door have strong thermal insulation properties to ensure that all heat is trapped in the cooking chamber, so that food is cooked faster and the heat utilization rate is high.

[0003] However, due to the limitations of processing conditions, material properties and processing costs, it is difficult for cooking devices to achieve absolute thermal insulation, and the heat in the cooking chamber will continue to diffuse outward. In particular, in order to facilitate users to observe the situation inside the cooking chamber, the door is usually made of glass, which is difficult to better insulate, resulting in the temperature of the glass outside the door and the handle installed on the door being relatively high, which can easily burn the user. In order to solve the problem of scalding, door handles are usually made of materials such as plastics with poor thermal conductivity and good strength. The heat on the glass outside the door will not be fully transferred to the door handle, making it safer to use.

[0004] The defects of existing door handles include: no matter whether the door handle is arc-shaped or L-shaped in cross section, its end is connected to the outer glass of the door, and the door handle and the outer glass of the door together form a gripping space. When opening the door, the user needs to put his fingers between the door handle and the outer glass of the door to hold the door handle stably. At this time, the back of the user's fingers and the back of the hand are easy to stick to the hot outer glass of the door, causing burns; in order to avoid contact with the hot outer glass of the door when grasping the door handle, the door handle can be designed to be far away from the outer glass of the door, which occupies a large space. The user is easy to bump into the door handle when moving in the kitchen, posing a safety hazard. Utility Model Content

[0036] This embodiment discloses a door handle, a door assembly including the door handle, and a cooking device including the door assembly. The cooking device may be, but is not limited to, a steamer, an oven, a microwave oven, or the like that can cook at high temperatures. Figure 1 As shown, the cooking device comprises a box body 6, a cooking chamber 7 for placing food to be cooked is formed in the box body 6, a heating element is arranged in the cooking chamber 7, and the heat generated by the heating element can cook the food to be cooked in the cooking chamber 7. The door assembly is connected to the box body 6, and the door assembly can open and close the cooking chamber 7 by swinging around the connection.

[0037] like Figures 1 to 4 As shown, the door assembly includes a door handle 1, an outer door body 2, an inner door body 3 and a door body fixing member 4. The outer door body 2 is bonded to the door body fixing member 4, and the inner door body 3 and the door body fixing member 4 are buckled. The outer door body 2 and / or the door body fixing member 4 form a mounting base for the door handle 1 to be connected. Connectors such as screws pass through the inner side of the door assembly to the outside and then fix the door handle 1 to the outer side of the door assembly.

[0038] like Figures 2 to 4 As shown, a handle portion 11 is formed inside the door handle 1, and the handle portion 11 includes at least one opening (not shown) for connecting to the external space of the door handle 1. The user can partially grasp the door handle 1 by inserting his hand into the handle portion 11 through the opening.

[0039] After the door handle 1 is connected to the mounting base, part of the wall of the door handle 1 separates the handle portion 11 from the mounting base. That is, the entire handle portion 11 (or gripping space) is surrounded by the door handle 1, and there is no need to use the outer surface of the door body assembly to surround the handle portion 11 like the existing handles. When the user's hand is inserted into the handle portion 11, the back of the hand and the back of the fingers touch the door handle 1, and will not touch the high-temperature outer door body 2 and / or door body fixing member 4, thus avoiding burns and making it safer to use.

[0040] The door handle 1 separates the handle portion 11 from the high-temperature outer door body 2, or the handle portion 11 and the door body fixing part 4, so that the user can avoid contact with the high-temperature outer door body 2 and / or the door body fixing part 4 without increasing the volume of the door handle 1 or increasing the distance protruding from the outer door body 2 and / or the door body fixing part 4, which is safer to use; it occupies a small space, and avoids the user from being hit by the door handle 1 when moving around the cooking device.

[0041] The specific material of the door handle 1 is not limited, as long as it has sufficient strength to open and close the door. For safer use, in this embodiment, the door handle 1 is made of a material with a low heat transfer coefficient such as plastic. The outer door body 2 and / or the door body fixing 4 are usually made of a material with a heat transfer coefficient greater than that of plastic, such as glass. The temperature limit for a user to get burned by contacting plastic parts is higher than the temperature limit for getting burned by contacting glass products. Even if the temperature on the outer door body 2 and / or the door body fixing 4 is fully transmitted to the door handle 1, it is not easy for the user to get burned.

[0042] The specific structure of the door handle 1 is not limited, as long as part of its wall surface can separate the handle portion 11 from the installation base after installation. In this embodiment, the door handle 1 includes a handle body 12 and a connected wall surface 13, and the connected wall surface 13 is connected to the end of the handle body 12 facing the installation base surface. The handle body 12 and the connected wall surface 13 form the handle portion 11, and the door handle 1 is connected to the installation base surface through the handle body 12 and / or the connected wall surface 13. The connected wall surface 13 is separated between the handle portion 11 and the installation base surface. When the user opens and closes the door, the back of the hand and the back of the fingers may abut against the inner surface of the connected wall surface 13, and will not directly contact the high-temperature outer door body 2 and / or the door body fixing part 4, which is safer to use.

[0043] The handle body 12 and the connecting wall 13 form a groove-shaped structure with an opening facing downward, and its cross section is an inverted U-shaped. In this structure, the upper side is the direct contact force-bearing part, and after the user's hand is inserted into the buckle handle 11, the fingers need to force against the position close to the upper side to better apply force.

[0044] In order to avoid scalding fingers and provide a better user experience, the upper side of the structure needs to be kept as far away from the high-temperature outer door body 2 and / or door body fixings 4 as possible, thereby reducing the temperature of the upper side of the structure. To achieve this goal, in the present embodiment, the minimum distance between the buckle handle portion 11 and the mounting base surface gradually increases along the direction from the opening of the buckle handle portion 11 to the inside of the buckle handle portion 11. Specifically, the connected wall surface 13 is inclined in the direction away from the mounting base surface, which can not only reduce the temperature of the upper side of the door handle 1, but also avoid excessive compression of the volume of the buckle handle portion 11 as much as possible. Hands of various sizes can comfortably fit into the buckle handle portion 11, and the scope of application is wider.

[0045] On the basis of the above structure, the door handle 1 is provided with a heat dissipation hole 14, which is located between the buckle portion 11 and the mounting base. In this embodiment, the heat dissipation hole 14 is located on the conjoined wall surface 13, and the heat dissipation hole 14 connects the buckle portion 11 to the mounting base. The heat between the mounting base and the conjoined wall surface 13 can be dissipated to the outside of the door handle 1 through the heat dissipation hole 14 and the buckle portion 11, thereby preventing the user from being scalded by high temperature.

[0046] The specific number, arrangement and shape of the heat dissipation holes 14 are not limited, and can be determined according to the area and shape on the connected wall surface 13, as long as the purpose of heat dissipation can be achieved. The specific size of the heat dissipation holes 14 is not limited. In order to avoid the user's fingers from being inserted by mistake, the diameter of the heat dissipation holes 14 is less than 6 mm, which is safer to use and prevents the user's fingers from passing through the heat dissipation holes 14 and contacting the high-temperature outer door body 2 and / or the door body fixing member 4.

[0047] On the basis of the above structure, the door assembly also includes a heat insulation structure that can block heat conduction, and the heat insulation structure is arranged between the door handle 1 and the heat source. The heat insulation structure has a good heat preservation effect and can reduce the cooking chamber 7 (such as Figure 1 The heat in the door handle 1 is transferred to the door handle 1 through the door body assembly, thereby preventing the user from being scalded and making it safer to use.

[0048] The specific structure of the heat insulation structure is not limited, and it can be a single device or a combination structure formed by multiple devices. Figures 5 to 7 As shown, the heat insulation structure is a single heat insulation member 5. The door body fixing member 4 faces the cooking chamber 7 (as shown in FIG. Figure 1 A mounting groove (not shown) is provided on one side of the door body, and a heat insulating member 5 is arranged in the mounting groove. The door handle 1 and the heat insulating member 5 are correspondingly located on both sides of the door body fixing member 4, thereby blocking the cooking chamber 7 (as shown in FIG. Figure 1 The heat in the door handle 1 is transferred to the door handle 1.

[0049] In order to improve the thermal insulation effect, the dimensions of the installation groove and the thermal insulation component 5 are slightly larger than the contact surface dimensions of the door handle 1 and the outer door body 2 and / or the door body fixing component 4. The thermal insulation component 5 can more fully insulate the door handle 1 and ensure that the temperature in a certain range around the door handle 1 is not too high.

[0050] The specific material for preparing the heat insulating member 5 is not limited, as long as it can effectively insulate. In this embodiment, the heat insulating member 5 is made of materials with low heat transfer coefficients such as super cotton fiber and rubber material, and has a good heat insulating effect.

[0051] The specific structure of the heat insulating member 5 is not limited. In this embodiment, the heat insulating member 5 includes a semiconductor cooling sheet. Semiconductor materials have a Peltier effect. When direct current passes through a couple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the couple. Specifically, the cooling end of the semiconductor cooling sheet faces the door handle 1, and the hot end of the semiconductor cooling sheet faces the cooking chamber 7 (such as Figure 1 As shown), the heat on the door handle 1 can be transferred to the cooking chamber 7 (as shown Figure 1 As shown), the temperature of the door handle 1 is reduced to avoid scalding the user.

[0052] On the basis of the above structure, the door assembly further includes a protective layer (not shown) capable of reducing heat radiation, and the protective layer is located on the side of the heat insulation structure facing the heat source. In this embodiment, the protective layer is made of low-radiation glass. The low-radiation glass firstly Figure 1 The heat radiation of the door handle 1 is reflected by the first layer to reduce the heat conduction. Then the heat insulation member 5 performs the second layer of physical heat insulation, which can effectively reduce the temperature on the door handle 1.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, but may also include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
