Description

Oven with heat emission structure

Technical Field

The present utility model relates to the field of household appliances for food processing. More particularly, the present utility model relates to an oven having a heat emitting structure.

Background

Nowadays, with the explosion of the baking industry, ovens are becoming an important cooking role in the home kitchen. The oven is a closed electric heating appliance for baking food, utilizes heat radiation emitted by a heating device to bake food materials, and has the characteristics of gentle cooking process, full food fermentation time, unique flavor of the food and the like. The oven can be used for processing some wheaten food such as bread and pizza, and also can be used for making desserts such as egg tarts and biscuits, and also can be used for cooking meat.

It is known that ovens provide a heating function mainly by means of a plurality of heating tubes arranged inside a cavity. In most ovens on the market, a plurality of heating pipes and a tray located below the plurality of heating pipes are provided in a cavity of the oven, wherein the tray is used for placing food to be baked. Because the distances between the heating tube and each position on the tray are unequal, the position of the tray right below the heating tube is heated more relative to the positions of the tray on two sides of the heating tube, so that the heating tube can bake food unevenly, and the taste and the appearance of the food are affected. Therefore, the temperature uniformity is an important index for evaluating the performance of the oven.

In the patent application publication number CN107049056a, an electric oven is provided which promotes uniformity of heating by a blower assembly. The fan assembly is arranged on the upper surface of the top plate and is used for supplying air to the central vent hole and sucking air from the vent hole of the outer ring so as to form air circulation in the cooking cavity. However, relying solely on the blower assembly obviously fails to deliver the airflow to any location within the cooking cavity, and has limited uniformity of heating the food.

In the patent application publication No. CN217723288U, an oven is provided which provides for more uniform heating of the food by reflecting a portion of the heat radiation emanating downwardly from the heat generating tube. The oven is provided with the heat reflecting piece in the cooking cavity, the heat reflecting piece is provided with the reflecting part at least partially positioned under the heating pipe, the reflecting part is utilized to reflect the heat radiation downwards dispersed by the heating pipe outwards, and the heat radiation of the heating pipe to the area under the heating pipe is reduced, so that the heat radiation received by all the positions in the cooking cavity is relatively uniform. However, the heat reflecting member disposed in the cooking cavity occupies a portion of the space of the cooking cavity, so that the space utilization of the cooking cavity is greatly reduced.

In view of the above, there is a need to provide an improved oven that enables uniform heating of food and has a high space utilization.

Accordingly, the following detailed description and drawings are merely illustrative of the utility model and are not intended to be exhaustive or to limit the utility model to the precise form disclosed.

Terms of orientation such as up, down, left, right, front, rear, front, back, top, bottom, etc. mentioned or possible to be mentioned in the present specification are defined with respect to the configurations shown in the drawings, which are relative concepts, and thus may be changed according to different positions and different use states thereof. These and other directional terms should not be construed as limiting terms. Furthermore, the terms "first," "second," "third," and the like are used for descriptive and distinguishing purposes only and are not to be construed as indicating or implying a relative importance of the corresponding components.

Referring first to fig. 1, there is shown a perspective view of an oven having a heat emitting structure according to an embodiment of the present utility model. As shown, the oven of this embodiment has a substantially rectangular parallelepiped shape and mainly includes a door assembly 1, a body assembly 2, and a base assembly 3. The door assembly 1 may be configured to move between an open position and a closed position. In particular, in the open position, a user can access a cavity (not shown) of the body assembly 2 for placing or removing food in or from the cavity; in the closed position, the door assembly 1 serves to close the cavity of the fuselage assembly 2 to ensure the safety of the toasting process. In addition, in order to facilitate the user to control the operation of the oven, the door assembly 1 may be further provided with an operation interface for man-machine interaction. In the embodiment shown in fig. 1, the base assembly 3 is positioned below the door assembly 1 and the body assembly 2 for stably supporting them on a supporting surface such as a dining table.

Turning now to fig. 2, an exploded view of the oven shown in fig. 1 is shown to illustrate in detail the oven, and in particular the internal components of the fuselage assembly 2. As shown, the body assembly 2 includes a cavity 212 defining a toasting space for receiving and toasting food. A plurality of trays (not shown) on which food to be toasted may be placed in the cavity 212. As shown in fig. 2, in an embodiment of the present utility model, the cavity 212 is provided at the top thereof with a plurality of grooves protruding upward from the top surface of the cavity 212 and extending along the length direction of the top surface. In the embodiment shown in fig. 2, three grooves are shown at the top of the cavity 212; however, it should be understood that any other suitable number of grooves are within the scope of the present utility model.

To perform the toasting function of the toaster, the body assembly 2 further comprises a heat emitting structure for heating the food item. As shown in fig. 2, the heat emitting structure includes a plurality of heating pipes 203 and a glass plate 228 positioned below the plurality of heating pipes 203. In this embodiment, the heating tube 203 is made of metal or quartz glass. In most ovens on the market, the heating tube is usually mounted at the top of the cavity of the oven, in particular below the top surface of the cavity. In such ovens, the heating tube located above the cavity occupies a portion of the toasting space, resulting in reduced space utilization of the cavity. In an embodiment of the utility model, each of the plurality of heating tubes 203 is positioned at least partially in a respective tongue at the top of the cavity 212. Preferably, the plurality of grooves are shaped and sized such that each of the plurality of heating tubes 203 can be completely accommodated in the corresponding groove. In this way, the heating tube 203 located in the convex groove does not occupy the baking space under the convex groove at all, so that the space utilization of the cavity 212 reaches 100%. Those skilled in the art will recognize that the number of heat pipes 203 corresponds to the number of grooves at the top of the cavity 212. In the embodiment shown in fig. 2, three heating pipes 203 are shown; however, it should be understood that any other suitable number of heat generating tubes 203 is within the scope of the present utility model, so long as the number of heat generating tubes 203 corresponds to the number of grooves.

With continued reference to fig. 2, and with simultaneous reference to fig. 3, fig. 3 shows an interior view of the oven shown in fig. 1. In fig. 3, the door assembly 1 has been removed for clarity. Fig. 3 clearly shows the assembled state of the heat emitting structure of the oven in the cavity 212 of the body assembly 2. In the embodiment of the present utility model, the plurality of heating tubes 203 are fixed to the cavity 212 by the heating tube fixing member 204. Preferably, the plurality of heating pipes 203 are arranged in parallel to each other in the respective convex grooves and positioned in the same plane parallel to the bottom surface of the cavity 212, i.e., positioned at equal vertical distances from the bottom surface of the cavity 212, which is advantageous in improving the uniformity of the oven. As shown in fig. 3, the glass plate 228 is fixed below the plurality of heating pipes 203 by a glass plate fixing frame 229. Preferably, the glass plate 228 is arranged parallel to the bottom surface of the cavity 212, and thus also parallel to the plane in which the plurality of heating tubes 203 lie, so that the vertical distances of the plurality of heating tubes 203 to the glass plate 228 are equal, which further ensures the temperature uniformity of the oven.

With further reference to fig. 3, the glass sheet 228 has a shape and size that substantially conforms to the cross-section of the cavity 212 (taken in a direction parallel to the bottom surface of the cavity 212). The design is such that the plurality of heating pipes 203 located above the glass plate 228 and the baking space located below the glass plate 228 are isolated by the glass plate 228. The heating tube can prevent a user from being scalded due to accidental touch with the heating tube when the user puts food into the heating tube, and can prevent foreign matters from falling into the food placed in the cavity after the heating tube is used for a long time.

With continued reference to fig. 2, and with simultaneous reference to fig. 4, fig. 4 shows a side cross-sectional view (taken in a direction perpendicular to the bottom surface of cavity 212) of the oven shown in fig. 1. The positioning of the plurality of heating tubes 203 and glass plate 228 relative to the plurality of grooves at the top of the cavity 212 can be clearly seen in fig. 4. In an embodiment of the present utility model, the plurality of grooves are shaped and sized such that each of the plurality of heating tubes 203 can be completely received in the corresponding groove. When the oven is powered on, the baking function is started, the heating tube 203 starts to heat, and the heat emitted by the heating tube 203 can be reflected by the oblique sides of the convex grooves, so that a global heat energy circulation loop is formed through the glass plate 228 positioned below the heating tube 203. As shown by the arrows in fig. 4, the heat emitting structure of the toaster according to the embodiment of the present utility model can generate a uniform heat distribution, so that foods located at different positions in the toasting space are heated uniformly, thereby greatly improving the uniformity of the temperature of the toaster.

To achieve precise control of the temperature inside the cavity 212, the body assembly 2 of the oven may also include at least one Negative Temperature Coefficient (NTC) thermistor. An NTC thermistor is a sensor resistor whose resistance value decreases with an increase in temperature. As shown in fig. 2, in an embodiment of the present utility model, at least one NTC thermistor 227 is provided at the top of the cavity 212 for precisely controlling the temperature inside the cavity 212, thereby ensuring that the food is baked uniformly without color cast.

In addition, to reduce heat dissipation and prevent users from being burned by touching the oven housing, the body assembly 2 of the oven may also include a plurality of heat shields. As shown in fig. 2, in an embodiment of the present utility model, the fuselage assembly 2 includes a top insulation panel 202, a left insulation panel 209, and a right insulation panel 216. The top insulating panel 202 is positioned over the top of the cavity 212. To better fit the top of the cavity 212, the top insulating panel 202 may have a plurality of grooves complementary to the plurality of grooves at the top of the cavity 212. In addition, left heat shield 209 and right heat shield 216 may be attached to the left and right sidewalls of cavity 212, respectively.

With continued reference to fig. 2, and with simultaneous reference to fig. 5, fig. 5 shows a rear view of the oven shown in fig. 1. In an embodiment of the present utility model, the body assembly 2 of the oven may further include a baking assembly 205 for assisting a baking function, a back cover plate 207 for closing and a louver 206 provided above the back cover plate 207, a cavity inner heat dissipation plate 208 for dissipating heat, and the like. The structure and function of these components are well known in the art and will not be described in detail herein.

In summary, compared with the prior art, the oven with the heat emission structure provided by the utility model has the technical effects of accurate temperature control, uniform heating, high space utilization rate, better protection of people and food and the like.

It should be understood that all of the above preferred embodiments are exemplary and not limiting, and that various modifications or variations of the above-described specific embodiments, which are within the spirit of the utility model, should be made by those skilled in the art within the legal scope of the utility model.
