Example 1:

referring to fig. 1 to 7, the present embodiment provides a door comprising a door body, a shutter 2, and a thermal deformation member 3.

The door body comprises a side plate 13, a first door plate 11 and a second door plate 12 which are oppositely arranged, the side plate 13 is positioned between the first door plate 11 and the second door plate 12, and the first door plate 11 and the second door plate 12 are fixedly connected through the side plate 13. The first door panel 11, the second door panel 12, and the side panels 13 enclose a heat dissipating cavity 14. In this embodiment, the second door panel 12 is located on a side of the first door panel 11 away from the steaming and baking integrated machine, and in other embodiments, the first door panel 11 may also be located on a side of the second door panel 12 away from the steaming and baking integrated machine.

The door body is provided with a heat dissipation opening 131, and the heat dissipation opening 131 is communicated to the heat dissipation cavity 14 so as to improve the heat dissipation performance of the door body. In the present embodiment, the heat dissipation port 131 is located on the side plate 13, so that the heat dissipation port 131 is located at the top of the door body, thereby facilitating the hot air to be exhausted from the heat dissipation chamber 14. The shape of the heat dissipation port 131 is not limited, and may be circular, positive, or other shapes, such as rectangular in the present embodiment.

The shutter 2 is located in the heat radiation chamber 14 and is movable so as to change the relative positional relationship with the heat radiation port 131. Depending on the relative positions between the shutter 2 and the heat radiation port 131, the shutter 2 has a shielding state and a dodging state.

The thermoform 3 is also mounted on the door body, more specifically inside the heat dissipation chamber 14 and at the side plates 13. The thermal deformation member 3 and the shielding member 2 keep a connection relationship, so that the thermal deformation member 3 can actively control the shielding member 2 through self thermal deformation action. The material of the thermal deformation member 3 may be nickel-titanium alloy, or may be other materials with a larger thermal expansion coefficient, such as aluminum alloy.

When the steaming and baking integrated machine is in a baking mode, the temperature of the first door plate 11 can rise to about 200 ℃, the temperature is higher at this time, the heat absorption capacity of the thermal deformation piece 3 is larger, so that the deformation capacity of the thermal deformation piece 3 is also larger, and the shielding piece 2 can move a larger distance relative to the initial position of the thermal deformation piece, so that the thermal deformation piece is in an avoidance state. When the shielding member 2 is in the avoidance state, the shielding member 2 can completely avoid or partially avoid the heat dissipation opening 131, so that the heat dissipation opening 131 is ensured to have enough area for the hot air in the heat dissipation cavity 14 to be discharged, and the heat dissipation effect of the oven door in the baking mode is ensured.

On the contrary, when the steaming and baking integrated machine is in the steaming mode or the normal temperature state, the temperature of the first door plate 11 is generally lower than 100 ℃ or at the room temperature, and at this time, the whole temperature of the first door plate 11 is not high, the corresponding thermal deformation piece 3 absorbs less heat, and the deformation amount is less or no deformation. The shutter 2 is thus moved little or no relative to its initial position, whereby the shutter 2 is in the blocking state. When the shielding member 2 is in the shielding state, the shielding member 2 shields the heat dissipation opening 131 partially or completely, so that the area of the heat dissipation opening 131 capable of supplying gas is reduced, water vapor outside the door cannot enter the heat dissipation cavity 14 or only slightly enters the heat dissipation cavity 14, and therefore the formation of condensed water in the heat dissipation cavity 14 is reduced, and the sealing effect of the door in the steaming mode is improved.

The steaming and baking integrated machine is gradually warmed up from a steaming mode or a normal temperature state to be changed into a baking mode, and the heat absorption capacity and the deformation capacity of the heat deformation member 3 are gradually increased in the process, so that the shielding member 2 is gradually changed from a shielding state to an avoiding state. In the gradual heating process of the door body, the deformation of the thermal deformation member 3 is gradually increased, and the area of the corresponding heat dissipation opening 131 for gas supply flow is also gradually increased, so that the area of the heat dissipation opening 131 for hot air and/or water vapor flow is always matched with the current door body temperature, thereby balancing the heat dissipation effect and the sealing effect of the door.

On the contrary, the steaming and baking integrated machine gradually reduces the temperature from the baking mode to the steaming mode or the normal temperature state, the thermal deformation piece 3 gradually releases heat, the deformation amount is reduced, and the shielding piece 2 is gradually converted into the shielding state from the avoiding state. Also, in this process, the area of the heat dissipation port 131 through which the hot air and/or the water vapor can flow is gradually changed and always matched with the current door body temperature, thereby balancing the heat dissipation effect and the sealing effect of the door.

In this embodiment, at least two heat dissipation ports 131 are provided and are spaced apart in the first direction. The shielding member 2 comprises a baffle plate extending along a first direction, and a plurality of avoiding openings 21 are formed in the baffle plate and matched with the distribution mode of the radiating openings 131. The number of the avoiding openings 21 is also generally plural, and is not less than the number of the heat dissipation openings 131, so as to ensure that each heat dissipation opening 131 has a corresponding avoiding opening 21. It will be readily appreciated that the larger the overlapping area of the heat dissipation port 131 and the corresponding escape port 21, the larger the area of the heat dissipation port 131 capable of supplying gas flow, the closer the shielding member 2 is to the escape state, the smaller the overlapping area of the heat dissipation port 131 and the corresponding escape port 21, the larger the area of the heat dissipation port 131 shielded by the shielding member 2, the smaller the area of the heat dissipation port 131 capable of supplying gas flow, and the closer the shielding member 2 is to the shielding state.

In this embodiment, the heat dissipation ports 131 are rectangular in shape, and have n number and b width. If the shutter 2 is moved by a distance a so that the area of the single heat radiation port 131 where the gas flows is changed by a×b, the total area change amount of the holes in the door where the gas flows is n×a×b. Even if the absolute value of a is small, the value of n×a×b is large as long as n is large. Correspondingly, in the case of a low thermal expansion coefficient of the thermal deformation member 3, the adjustable amount of the area of the door body through which the gas can flow is also extremely large.

In order to maximize the heat radiation performance of the heat radiation port 131 when the shield 2 is in the retracted state, the shield 2 has a complete retraction effect on the heat radiation port 131, and therefore the length (in the first direction) of the retraction port 21 is not smaller than the length (in the first direction) of the heat radiation port 131.

The length of the heat dissipation port 131 is m ₂ The distance m between two adjacent avoidance ports 21 ₁ In order to prevent water vapor from entering the heat dissipation cavity 14 to the maximum extent when the shielding member 2 is in the shielding state, the shielding member 2 can completely shield the heat dissipation opening 131, namely m ₁ ≥m ₂ 。

In order to ensure that the gas flow area of all the heat dissipating ports 131 is simultaneously increased and simultaneously decreased, it is necessary to ensure the length m of the heat dissipating ports 131 ₂ Spacing m between two adjacent heat dissipation ports 131 ₄ Length m of the avoidance port 21 ₃ Spacing m between two adjacent avoidance ports 21 ₁ Are all constant and m ₂ ＝m ₃ ，m ₁ ＝m ₄ . Further, in order to ensure that the conduction area of the heat dissipation port 131 can be changed by moving the shutter 2, m needs to be satisfied ₂ ＝m ₃ ＝m ₁ ＝m ₄ 。

The inner wall department of heat dissipation chamber 14 is provided with locating part 141, and the locating part 141 is a rib for one in this embodiment, and the locating part 141 plays spacing effect to shielding member 2 for shielding member 2 is laminated with the inner wall of heat dissipation chamber 14 all the time, and when shielding member 2 played the shielding effect to thermovent 131, the shielding member 2 can not exist the gap between the part that shields thermovent 131 and thermovent 131, is difficult to the gas to flow, so ensure that shielding member 2 effectively shelters from thermovent 131.

Further preferably, the limiting member 141 and the inner wall of the heat dissipation cavity 14 enclose a guiding groove 142, the shielding member 2 and the thermal deformation member 3 are both at least partially positioned in the guiding groove 142, the deformation direction of the thermal deformation member 3 is limited by using the guiding groove 142, and the moving direction of the shielding member 2 and the deformation direction of the thermal deformation member 3 are ensured to be consistent, so that the effectiveness of the thermal deformation member 3 on the movement control of the shielding member 2 is ensured.

Because the thermal deformation member 3 is in the heat dissipation cavity 14 and cannot directly contact with the inside of the box body of the steaming and baking integrated machine to absorb heat and directly contact with the outside of the heat dissipation cavity 14 to release heat, the heat absorption and release efficiency is affected to a certain extent, and therefore, the thermal deformation member 3 can have certain hysteresis on the movement control of the shielding member 2 along with the temperature change in the box body. To solve this problem, the door of the present embodiment further includes a heat conducting member 4, wherein a portion of the heat conducting member 4 is located at the junction between the side plate 13 and the first door panel 11, and another portion is located in the heat dissipating cavity 14 and contacts the heat deformable member 3. Under the roast mode, first door plant 11 just is just steaming and baking the box inside of all-in-one, and the inside heat of box can be directly conducted to heat conduction spare 4 that heat conductivility is good through first door plant 11, is conducted the heat to thermal deformation spare 3 by heat conduction spare 4 for thermal deformation spare 3 can deform more fast, with the inside temperature rise process of quick response box. When the box door is opened on the box body, the side plate 13 is farthest from the box body, so that the heat conducting piece 4 can conduct heat on the thermal deformation piece 3 to the side plate 13 rapidly, the heat is dissipated through the side plate 13, the cooling efficiency of the thermal deformation piece 3 is accelerated, the shielding piece 2 seals the heat dissipation opening 131 more rapidly, and condensed water is reduced to enter the heat dissipation cavity 14.

Wherein the heat conducting member 4 is positioned on the side plate 13 and/or the first door panel 11, for example, in this embodiment, it is clamped on the side plate 13, so as to inhibit thermal deformation of the heat conducting member 4. Both ends of the thermal deformation member 3 are provided on the heat conductive member 4 and the shielding member 2, respectively. Under the condition that the thermal deformation of the heat conducting piece 4 is restrained, the thermal variable of the thermal deformation piece 3 can be always converted into the displacement of the shielding piece 2 to the maximum extent, and therefore the movement control precision of the thermal deformation piece 3 on the shielding piece 2 is improved.

It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
