Description

Embedded oven

Technical Field

The utility model relates to the technical field of household appliances, especially, relate to an embedded oven.

Background

With the improvement of living standard, the embedded oven gradually enters the home of common people. The embedded oven not only can enable the kitchen to be cleaner and tidier, but also can save more operation spaces of the table board.

The embedded oven is internally provided with a heating tube, the heating tube heats to raise the temperature in the inner container, and the food in the inner container is cooked by high temperature. However, since the heat in the inner container is easy to diffuse to the periphery, high temperature is also existed around the inner container, and especially the diffused high temperature is easy to damage the control panel above the inner container and various electrical components connected with the control panel, which affects the service life of the control panel, a flow guide cavity is arranged on the upper part of the inner container, and cold air is discharged from the flow guide cavity through a cross flow fan to take away the heat.

However, crossflow blowers are generally large in size and therefore lose space inside the inner bladder. Also, the cross flow fan itself is costly, thus resulting in a high cost of the drop-in oven.

SUMMERY OF THE UTILITY MODEL

In order to at least partially solve the problems of the prior art, according to an aspect of the present invention, there is provided a built-in oven including: the heat dissipation channel is positioned between the shell and the inner container of the embedded oven, and the control element of the embedded oven is positioned in the heat dissipation channel; and a centrifugal fan in the heat dissipation channel and close to the control element for discharging hot air in the heat dissipation channel.

Through setting up heat dissipation passageway and centrifugal fan for embedded oven, can reduce the influence of the heat that is radiated by the inner bag to control element, improve control element's life. Compared with the prior art using a crossflow blower, the centrifugal blower is relatively low in cost and low in noise. Meanwhile, the centrifugal fan can occupy smaller space while ensuring that the heat dissipation effect is not reduced. Therefore, the volume of the embedded oven can be made smaller under the condition that the used volume is not changed, and the cost of the product is further reduced.

Illustratively, the number of the centrifugal fans is multiple. Therefore, the air outlet quantity can be increased, more heat can be discharged in unit time, and the heat dissipation efficiency is improved.

Illustratively, the centrifugal fan is a direct flow centrifugal fan. The heat dissipation device has the characteristics of low cost, small size and the like, and particularly has obvious advantages in a narrow heat dissipation channel of an embedded oven.

Illustratively, the centrifugal fan is disposed near the inner container, wherein the air inlet of the centrifugal fan is located at a side of the centrifugal fan facing away from the inner container. Therefore, when the centrifugal fan works, the air inlet is far away from the inner container, so that the sucked air is cold air with relatively low temperature, and is discharged through the heat dissipation channel, and meanwhile, the heat in the heat dissipation channel is taken away.

The embedded oven also comprises a flow guide cavity, wherein the flow guide cavity is arranged in the heat dissipation channel, and an inlet of the flow guide cavity is communicated to the centrifugal fan and an outlet of the flow guide cavity is communicated to an air outlet of the heat dissipation channel.

The diversion cavity is used for guiding the mixed cold and hot air to the air outlet and then discharging the mixed cold and hot air. Therefore, the efficiency of taking away heat by cold air can be improved, and the control element can be better protected.

Illustratively, the number of the centrifugal fans is plural, and the baffle chamber has inlets corresponding to the number of the centrifugal fans so as to communicate each of the centrifugal fans to the corresponding inlet.

Therefore, on one hand, air turbulence caused by the operation of the centrifugal fans 300 can be reduced, and the air exhaust efficiency is improved. On the other hand, the inlets 510 corresponding to the number of the centrifugal fans 300 are provided, so that the installation and connection of the inlets and the diversion cavity 500 are facilitated, and the disassembly and the maintenance are more convenient.

Exemplarily, the diversion cavity is trumpet-shaped, the export in diversion cavity is located the jumbo size end in diversion cavity, centrifugal fan sets up the small-size end in diversion cavity.

Therefore, when the gas discharged by the centrifugal fan is blown to the large-size end from the small-size end, the flow velocity of the gas is reduced because the cross-sectional area of the flow guide cavity is increased, and the pressure of the gas is reduced from the small-size end to the large-size end. The temperature of hot gas is reduced, the damage to the control element caused by the high-temperature gas is reduced, and the service life of the control element is prolonged. And because the air inlet is usually arranged on the front side of the embedded oven, the air pressure is reduced, so that the influence of a user on the user when the user is on the front side of the embedded oven can be avoided. And the fan sets up the small-size end in the water conservancy diversion chamber, under the condition that can improve centrifugal fan's the effect of airing exhaust, has still saved the material, the cost is reduced.

Exemplarily, the built-in oven further comprises a partition plate arranged at the outer side of the inner container, a cover plate is arranged on the partition plate, and the cover plate and the partition plate form the diversion cavity.

The baffle plate and the cover plate form the flow guide cavity, so that the structure of the embedded oven is simpler and the embedded oven is easy to process and manufacture.

Illustratively, the control panel of the built-in oven is spaced apart from the door panel to form the air outlet of the heat dissipation channel. Therefore, the air outlet is provided for the heat dissipation channel under the condition that the overall appearance of the embedded oven is not damaged, so that the overall structure is more compact and attractive.

Illustratively, the heat dissipation channel is located above the inner container. The control panel of the built-in oven and its electronic components are typically disposed above the inner container. In addition, since the hot air is easily diffused upward, it is very advantageous to provide a heat dissipation member above the inner container.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the present invention and are not intended to limit the invention to the particular embodiments described herein. Based on the embodiments of the present invention described in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

The utility model provides an embedded oven. Built-in ovens are typically mounted within a cabinet with only the front of the built-in oven where the door panel is located exposed. A control panel is usually further disposed around the door panel, and the control panel is used for controlling the operation mode, parameters and the like of the built-in oven. The control panel is typically integrated with the electronics for control, however, these electronics may be separate from the control panel. Based on this, they are collectively referred to as control elements. When the embedded oven works, heat generated in the inner container of the embedded oven can radiate outwards. This heat, if not even evacuated to the outside, may cause damage to the control elements.

As shown in fig. 1 and 3, the control panel 130 of the built-in oven 100 and its electronic components are generally disposed above the inner container 120. In addition, since the hot air is easily diffused upward, it is very advantageous to provide a heat dissipation member above the inner container 120. Thus, the principles of the present invention are described below and illustrated in the drawings by way of example with the control elements and heat dissipation elements disposed above the inner bladder. However, those skilled in the art will appreciate that the control elements and heat dissipation components can be located elsewhere, such as on the sides or below the liner, if desired.

As shown in fig. 1-2, the heat dissipating components mentioned above may include heat dissipating channels 200 and a centrifugal fan 300. The heat dissipation channel 200 is located between the housing 110 and the inner container 120 of the built-in oven 100, for example, between a top wall of the inner container 120 and a top wall of the housing 110. The control elements of the built-in oven 100 are located within the heat dissipation channel 200. The heat dissipation channel 200 may be collectively formed by the case 110, the inner container 120, and the control panel 130. The intake vent 210 of the heat dissipation channel 200 may be disposed on the housing 110. The air outlet 220 is typically disposed in front of the recessed oven 100 to vent hot air to the environment. When the built-in oven 100 is in operation, heat generated in the inner container 120 is radiated into the heat dissipation channel 200.

Illustratively, the control panel 130 may be disposed in a spaced apart relation from the door panel 140 of the toaster oven 100, with the air outlet 220 of the heat dissipation channel 200 being located in the space therebetween. Therefore, the air outlet 220 is provided for the heat dissipation channel 200 without damaging the overall appearance of the built-in oven 100, so that the overall structure is more compact and beautiful.

For example, the air inlet 210 of the heat dissipation channel 200 may be located at the rear of the housing 110 (see fig. 1) and at the side of the housing 110 (see fig. 3). The rear and side surfaces of the housing 110 may be provided with the air inlets 210 at upper and lower portions thereof. Therefore, when the centrifugal fan 300 works, not only the heat can be dissipated above the inner container 120, but also the heat can be dissipated to the back and the side of the inner container 120, thereby prolonging the service life of the cabinet of the built-in oven 100.

The centrifugal fan 300 is disposed in the heat dissipation passage 200, and adjacent to the control panel 130, for discharging hot air in the heat dissipation passage 200. The centrifugal fan 300 is also called a radial fan, i.e. the air flow direction is perpendicular to the fan's axis of rotation. When the centrifugal fan 300 works, the impeller is driven by the motor to rotate, the blades in the impeller force the gas to rotate, the gas applies work to increase momentum, the gas is thrown out to the periphery of the impeller under the action of centrifugal force, kinetic energy is converted into pressure energy through the scroll casing, after the gas in the impeller is discharged, the pressure in the impeller is lower than the pressure in the air inlet pipe, new gas is sucked into the impeller under the action of pressure difference, and the gas is continuously discharged from the fan. In this way, the cooling air can be sucked in by the centrifugal fan 300 and discharged from the heat dissipating passage 200, and the heat radiated from the inner container 120 in the heat dissipating passage 200 can be taken away.

Preferably, centrifugal fan 300 may be a direct flow centrifugal fan. The centrifugal fan 300 suitable for application to the built-in oven 100 is a small centrifugal fan because of a limited space therein. Typically, the small centrifugal fan is a dc centrifugal fan. The working voltage of a common direct current centrifugal fan is 12V or 24V, and of course, other specifications exist, which are not illustrated here. It has characteristics such as with low costs, small, especially in embedded oven 100's narrow and small heat dissipation channel, has obvious advantage.

By providing the built-in oven 100 with the heat dissipation channel 200 and the centrifugal fan 300, the influence of the heat radiated from the inner container 120 on the control element can be reduced, and the service life of the control element can be improved. Centrifugal fan 300 is relatively low cost and less noisy than prior art cross-flow fans. Meanwhile, the centrifugal fan 300 can occupy a smaller space while ensuring that the heat dissipation effect is not reduced. Therefore, the volume of the built-in oven 100 can be made smaller without changing the volume of the used oven, and the cost of the product is further reduced.

For example, the centrifugal fan 300 may be plural, for example, two, three or more, in order to achieve better heat dissipation effect. A plurality of centrifugal fans 300 may be installed side by side in the heat dissipation passage 200. Therefore, the air outlet quantity can be increased, more heat can be discharged in unit time, and the heat dissipation efficiency is improved. The number of centrifugal fans 300 may be selected by one skilled in the art based on such parameters as the power rating of the centrifugal fans 300 and the power rating of the built-in oven. Further, the plurality of centrifugal fans 300 may be disposed close to each other or may be disposed at a large interval from each other. In the illustrated embodiment, the air inlet of the centrifugal fan 300 extends in a vertical direction, for example, the air inlet may face upward or downward. And the outlet is directed toward the front of the toaster 100. When a plurality of centrifugal fans 300 are provided, it is desirable that the vortex flow generated by each centrifugal fan 300 can uniformly bring the hot air out of the heat dissipation passage. Therefore, the positions of the plurality of centrifugal fans 300 may be arranged according to the distribution of the air inlets of the heat dissipation passage.

Illustratively, the centrifugal fan 300 is disposed adjacent to the inner container 120, wherein the air suction opening 310 of the centrifugal fan 300 is located on a side of the centrifugal fan 300 facing away from the inner container 120, as shown in fig. 1. For the centrifugal fan 300 shown in the figures mounted above the inner container 120, the air suction opening 310 of the centrifugal fan 300 may be directed upward. When the centrifugal fan 300 is installed at a side, the air inlet of the centrifugal fan 300 may be outward in a horizontal direction. Thus, when the centrifugal fan 300 is operated, the air inlet 310 is far away from the inner container 120, so that the sucked air is relatively low-temperature cold air, and is discharged through the heat dissipation channel 200, and simultaneously takes away heat in the heat dissipation channel 200.

Illustratively, the recessed oven 100 further includes a deflector cavity 500. The diversion cavity 500 is disposed in the heat dissipation channel 200, an inlet 510 of the diversion cavity 500 is communicated to the centrifugal fan 300, and an outlet 520 is communicated to the air outlet 220 of the heat dissipation channel 200. The diversion cavity 500 may be disposed close to the inner container 120, or may be spaced apart from the inner container 120 by a certain distance. Preferably, for installation convenience, the diversion cavity 500 is tightly attached to the inner container 120. As shown in fig. 1, when the centrifugal fan 300 is operated, air may flow along the path of arrows a-B, and the centrifugal fan 300 sucks cold air through the air inlet 210 to mix with hot air in the heat dissipation channel 200, blows the cold air through the inlet 510 of the baffle chamber 500, and then is discharged out of the built-in oven 100 through the outlet 520 and the air outlet 220 of the baffle chamber 500 in sequence. In fact, the diversion cavity 500 functions to guide the mixed cold and hot air to the air outlet 220 and then to be discharged. Therefore, the efficiency of taking away heat by cold air can be improved, and the control element can be better protected.

For example, in the case where the number of the centrifugal fans 300 is plural, the baffle chamber 500 has inlets 510 corresponding to the number of the centrifugal fans 300, so that each centrifugal fan 300 communicates to the corresponding inlet 510. The centrifugal fans 300 may be respectively disposed at the corresponding inlets 510. Therefore, on one hand, air turbulence caused by the operation of the centrifugal fans 300 can be reduced, and the air exhaust efficiency is improved. On the other hand, the inlets 510 corresponding to the number of the centrifugal fans 300 are provided, so that the installation and connection of the inlets and the diversion cavity 500 are facilitated, and the disassembly and the maintenance are more convenient.

Illustratively, the diversion cavity 500 is trumpet-shaped, the outlet 520 of the diversion cavity 500 is located at the large-sized end, and the centrifugal fan 300 is disposed at the small-sized end of the diversion cavity 500.

Because the specification of the centrifugal fan 300 has a uniform standard and is not particularly large, in order to enable the centrifugal fan 300 to generate a good negative pressure effect in the diversion cavity 500, the size of the centrifugal fan 300 is matched, and the connecting end of the diversion cavity 500 and the centrifugal fan 300 is set to be a small-size end. Under the condition of improving the air exhaust effect of the centrifugal fan 300, the material is saved, and the cost is reduced.

And the outlet 520 of the baffle chamber 500 is disposed at the large-sized end. The reason is that when the gas discharged from the centrifugal fan 300 is blown from the small-sized end to the large-sized end, the flow velocity of the gas will be reduced because the cross-sectional area of the baffle cavity 500 is increased, and the pressure of the gas is also reduced from the small-sized end to the large-sized end. The temperature of hot gas is reduced, the damage to the control element caused by the high-temperature gas is reduced, and the service life of the control element is prolonged. And since the air inlet 210 is generally disposed at the front of the recessed oven 100, the reduction of the air pressure can avoid the influence of the user on the user when the user is at the front of the recessed oven 100.

Typically, the outer surface of the inner container 120 is wrapped with an insulation layer 400. The heat insulating layer serves to prevent heat from radiating to the outside of the inner container 120 to some extent. Insulation layer 400 generally has a softer texture. Based on this, a partition 600 is provided, and the partition 600 is disposed at the outer side of the inner container 120, as shown in fig. 2. A cover plate 530 is disposed on the partition 600, and the cover plate 530 and the partition 600 form a diversion cavity 500. The spacer 600 may be provided only at a position corresponding to the cap plate 530 to save materials. The partition 600 may be coupled to a frame of the drop-in oven 100, such as to a door frame, a housing, and/or a liner of the drop-in oven 100. Thereby providing support for the cover plate 530.

The baffle plate 600 and the cover plate 530 form the baffle cavity 500, so that the structure of the built-in oven 100 is simpler and the manufacture is easier.
