detailed description

The present invention is described below based on examples, but the present invention is not limited to these examples.

Referring to FIG. 1 ( FIG. 1 is a schematic structural diagram of a cooker according to the first embodiment of the present invention), the cooker includes a panel and a bottom case 1 , and the panel is arranged on the bottom case 1 .

The panel includes a middle board 2 and a cover board 3 . That is, the panel is implemented as a double-layer panel structure including the middle panel 2 and the cover panel 3 . The positions and sizes of the panel holes (that is, the burner through holes) of the middle plate 2 and the cover plate 3 are consistent, so as to facilitate the installation of the burner. The middle plate 2 is fixed (for example, by screws) on the bottom case 1 . The cover plate 3 is fixed on the middle plate 2 (for example, as shown in Figure 1, the cover plate 3 can be sleeved on the middle plate 2), so that there is a gap between the middle plate 2 and the cover plate 3, which is suitable for heat dissipation and / or insulation. The cooking range also includes a wind wheel assembly 4 (corresponding to the exhaust device of the present invention) which is suitable for discharging the hot air inside the cooking range. cavity (ie, the set-up space as will be further described below). Here, it should be pointed out that other suitable exhaust devices can also be used instead of the wind wheel assembly 4 .

A cavity is formed between the bottom case 1 and the middle plate 2 , and the middle plate 2 is provided with an exhaust hole 12 , thereby forming an exhaust channel 5 from the cavity to the gap via the exhaust hole 12 . In a preferred example, the exhaust hole 12 is a gap disposed in the middle of the middle plate 2 , extending along the front-to-rear direction, and located between the two burner through-holes 13 .

In the illustrated example, the bottom shell 1 is a disc-shaped member with an open upper side and notches are provided at the side ends (for example, left and right side ends) of the bottom shell 1, and gaps are provided at the side ends (such as left and right side ends) of the middle plate 2. A first bending part 11 is provided, and a second bending part 14 is provided at the side ends (for example, left and right side ends) of the cover plate 3, so that at the side ends (for example, one or all of the left and right side ends) of the cooker Two side ends) form an installation space defined by the bottom shell 1 , the middle plate 2 and the cover plate 3 , the installation space is directly connected to the gap and separated from the cavity by the first bent portion 11 .

The air exhaust device (such as the wind wheel assembly 4) is arranged in the installation space, so that when the air exhaust device operates, the gas is forced to flow from the air vent 9 provided at the bottom shell 1 (such as two holes on the rear side of the bottom shell) mouth) into the cavity, flow to the installation space through the exhaust channel 5, and then be discharged from the installation space to the outside of the cooker. In this way, effective heat dissipation is achieved on the one hand, and sufficient supply of primary air is improved on the other hand (ie, fresh air is promoted to enter the interior of the cooker from the vent hole 9, thereby providing sufficient primary air at the nozzle).

In some examples, an air outlet is provided at the second bent portion 14 of the cover plate 3 (for example, the air outlet may be located at the lower end of the second bent portion 14 so as to be adjacent to the upper surface of the bottom case 1 ), the gas is discharged from the installation space to the outside of the cooker through the exhaust port.

In the illustrated example, the wind wheel assembly 4 has a wind wheel 7 and a support seat 8 , and the wind wheel assembly 4 is fixed to the bottom shell 1 through the support seat 8 without interfering with the middle plate 2 and the cover plate 3 . For example, two support seats 8 are provided for the wind wheel 7 to support the two ends of the wind wheel 7 . Thus, since the wind wheel assembly 4 does not interfere with the middle plate 2 and the cover plate 3 and is only installed on the relatively strong bottom shell 1 , the vibration of the middle plate 2 and the cover plate 3 due to the operation of the wind wheel assembly 4 can be avoided.

The wind wheel assembly 4 also includes a motor 6 for powering the wind wheel 7 , and the motor 6 is mounted on the bottom case 1 . In some examples, unlike the wind wheel 7 of the wind wheel assembly 4 installed in the installation space, the motor 6 of the wind wheel assembly 4 can be installed in the cavity between the bottom shell 1 and the middle plate 2 away from the wind wheel 7 .

In some examples, the motor 6 is connected to the rotary switch of the cooker, so that the motor 6 is started synchronously or with a predetermined time delay when the rotary switch is turned on, and is turned off synchronously or with a predetermined time delay when the rotary switch is turned off.

5, in the cooker according to the second embodiment of the present invention, the cooker further includes a temperature sensor 15, and the motor 6 is connected to the temperature sensor 15, so that the motor 6 is started when the temperature sensed by the temperature sensor 15 is higher than the first predetermined threshold. And when the temperature sensed by the temperature sensor 15 is lower than the second predetermined threshold, the motor 6 is turned off (here, the first predetermined threshold may be higher than the second predetermined threshold). In this way, intelligent and controllable cooling can be realized, and at the same time, it is beneficial to save energy. In a preferred example, the temperature sensor 15 is disposed on the middle plate 2 , especially, the temperature sensor 15 may be disposed at or near the furnace head (the through hole of the furnace head) between the middle board 2 and the cover plate 3 . In this way, the temperature or the maximum temperature in the hob can be reliably monitored.

The middle plate 2 is provided with a downwardly recessed channel 16 (for example, an arc-shaped channel extending on the entire middle plate 2 along the front-rear direction of the cooker). A temperature sensor 15 may be arranged at the channel 16 . In addition, the burner head through holes on the middle plate 2 can be arranged at the channel 16 . Thus, since the recessed channel is provided and the burner through-hole with higher temperature is arranged at the channel, it is possible to avoid excessive rise in temperature of internal parts due to untimely heat removal.

Here, it should be pointed out that although the cooktops in the first embodiment and the second embodiment both include an exhaust assembly in the above description, it can be understood that the exhaust assembly can be dispensed with. In this case, since the panel is improved from a single-layer panel structure to a double-layer panel structure, the insulation effect of the middle plate can still prevent excessive heat from spreading into the cavity between the bottom shell 1 and the middle plate 2, Critical components arranged in the cavity can thus be protected from excessive temperature rise.

In a word, according to the present invention, since the single-layer panel is changed into a double-layer panel, most of the heat can be discharged before it reaches the inside of the cooker, greatly reducing the internal temperature of the cooker, and protecting important components in the cooker from being damaged. Moreover, since heat is continuously exported to the cooker, the temperature of the cover plate and the knob can also be reduced, increasing user comfort. In addition, a temperature sensor is installed at the through hole of the burner between the middle plate and the cover plate. When the air temperature between the cover plate and the middle plate reaches a certain level, the signal is transmitted to the motor to drive the wind wheel to start working. When it is lower than a certain value, it will stop working, so as to save resources and unnecessary loss. In addition, the air flow inside the cooker can be enhanced to facilitate the supply of primary air.

The above descriptions are only exemplary embodiments and modifications of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have many different modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
