Description

Technical Field

[0001] The invention relates to the field of cooking equipment, and in particular to a cooking liner structure with a baking function and a steam oven. Background Art

[0002] A steam oven is a cooking device that has both steaming and baking functions. In order to achieve better cooking effects during both steaming and baking functions, two exhaust ports are generally provided, one of which is a normally open exhaust port and the other is a variable exhaust port. For example, the Chinese utility model patent "A steaming and baking exhaust structure and steam oven" with patent number ZL202121478954.5 (authorization announcement number CN216293800U)

[0003] Furthermore, in the prior art, the opening and closing of the variable exhaust port is generally controlled by a wax motor. For example, the exhaust port is closed during the steaming function, and steam is discharged from the normally open exhaust port. When baking food that is sensitive to moisture, the openable and closable exhaust port is opened to enhance the dehumidification capacity of the inner pot. However, when baking food with a high moisture content (baking cakes, chicken wings, etc.), even if the two exhaust ports are opened at the same time, the demand for rapid dehumidification cannot be met (due to the size limitation of the top wall of the inner pot and the need to seal the inner pot during the steaming function, the size of the exhaust port cannot be made too large), which results in poor baking effect of the existing steam oven for food with high moisture content. Summary of the invention

[0004] The first technical problem to be solved by the present invention is to provide a cooking pot structure with good dehumidification effect and baking function in view of the prior art.

[0005] The second technical problem to be solved by the present invention is to provide a steam oven including the above-mentioned cooking liner structure in view of the prior art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a cooking liner structure with a grilling function, comprising:

[0007] Inner liner, front opening;

[0008] The door body is used to cover the opening of the inner container; it is characterized in that it also includes a humidity control component, which includes:

[0009] A humidity control chamber capable of exchanging heat with the interior of the inner tank;

[0010] The first substance is contained in the humidity control chamber and can be vaporized under heating to increase the internal pressure of the humidity control chamber;

[0011] A push rod is arranged along the front-to-back direction, and the rear end thereof is passed through the through hole of the wall of the humidity control chamber, while the front end thereof is located outside the humidity control chamber and can abut against the inner surface of the door body;

[0012] Furthermore, in the initial state, the door body covers the opening of the inner pot. In the baking mode, when the temperature inside the inner pot rises to the set temperature, the push rod moves forward under the action of the front and rear pressure difference to push the door body and form a moisture-desorption gap between the door body and the opening edge of the inner pot.

[0013] Furthermore, the humidity control chamber is arranged outside the inner liner, which facilitates the arrangement of the humidity control chamber and does not affect the internal volume of the inner liner.

[0014] Furthermore, it also includes a block-shaped humidity control seat, which is attached to the outer surface of the inner liner and is hollow to form the humidity control cavity, so that the humidity control cavity structure can be formed well and heat exchange between the humidity control cavity and the inner liner can be facilitated.

[0015] Furthermore, the humidity control seat is attached to the outer surface of the front upper part of the inner pot, and the moisture removal gap is formed between the upper end of the door body and the upper edge of the inner pot opening. On the one hand, the door body of the cooking device is generally arranged to rotate up and down, so the above arrangement can extend the force arm of the push rod, thereby facilitating the push rod to push the door body open; on the other hand, hot air has the characteristic of rising upwards, and the moisture removal gap is arranged at the upper end to ensure the moisture removal effect.

[0016] Furthermore, the humidity control seat is attached to the junction of the left wall or right wall of the inner liner and the top wall, and the attached surface of the humidity control seat connected to the inner liner matches the outer surface of the inner liner at that location, thereby increasing the contact area between the humidity control seat and the inner liner surface, thereby improving the heat exchange efficiency between the humidity control cavity and the inner liner, and thus improving the response speed of the push rod.

[0017] Furthermore, the shape of the humidity control seat is square and is arranged horizontally, and the lower inner side thereof is concave to form the above-mentioned arc-shaped attachment surface, and an upper mounting piece is fixed on the inner side surface of the humidity control seat, and the upper mounting piece is horizontally arranged on the top surface of the above-mentioned inner liner and is fixed to the first mounting seat arranged on the top surface of the inner liner through a first fastener, and a lower mounting piece is fixed on the bottom surface of the humidity control seat, and the lower mounting piece is vertically arranged outside the left side wall or right side wall of the inner liner and is fixed to the mounting seat arranged on the outer side surface of the inner liner through a second fastener. Thereby, the humidity control seat can better form the above-mentioned attachment surface, and at the same time, the humidity control seat can be stably arranged on the inner liner.

[0018] Furthermore, the through hole is provided on the front side wall of the humidity control seat, and a return spring is sleeved on the push rod.

[0019] In the initial state, the reset spring is in a naturally extended state, and when the temperature inside the inner tank rises to a set temperature, the reset spring is compressed, causing the push rod to move backward and reset, thereby achieving automatic reset of the push rod.

[0020] Furthermore, the push rod is cylindrical in shape and includes a mounting portion at the rear end and a supporting portion at the front end. The radius of the supporting portion is smaller than that of the mounting portion. The mounting portion is inserted into the through hole and can move forward and backward relative to the edge of the through hole. A clamping annular surface is formed at the junction of the supporting portion and the mounting portion.

[0021] In addition, a mounting cover extending forward and backward is provided on the front side of the humidity control seat at the through hole, the push rod is arranged in the mounting cover along the central axis direction of the mounting cover, and a mounting hole for the top holding part of the push rod to pass through is provided on the front end wall of the mounting cover, and the reset spring is clamped between the inner end surface of the mounting cover and the clamping annular surface. Thus, the reset spring can be stably arranged, and the push rod can also move forward and backward smoothly.

[0022] Furthermore, a mounting boss is convexly provided on the front surface of the humidity control seat, the edge of the through hole extends outwardly in the circumferential direction and penetrates the mounting boss to form a guide channel, the mounting portion of the push rod is inserted in the guide channel and can move back and forth along the guide channel, and the mounting cover is covered on the mounting boss. In this way, the push rod can move forward and backward more smoothly.

[0023] Furthermore, a limiting rod is transversely arranged in the inner port of the guide channel, and in an initial state, the rear end of the push rod abuts against the limiting rod, thereby stably limiting the push rod in the initial state.

[0024] Furthermore, a door lining is provided around the opening edge of the inner container, and a guide hole is provided on the door lining for the front end of the push rod to pass through and the size of which matches the front end of the push rod. On the one hand, the front end of the push rod can smoothly abut against the inner surface of the door body, and on the other hand, the push rod can move forward and backward more smoothly through the guidance of the guide hole.

[0025] Furthermore, the first substance is water, so that when the temperature in the humidity control chamber exceeds 100°C, the water vaporizes and increases the internal pressure of the humidity control chamber, thereby pushing the push rod forward; when the temperature in the humidity control chamber drops, the vaporized water re-liquefies and the internal pressure of the humidity control chamber drops.

[0026] The technical solution adopted to further solve the second technical problem mentioned above is: a steam oven, characterized in that it includes the cooking inner pot structure with baking function as described above.

[0027] Compared with the prior art, the present invention has the advantages that the humidity control chamber can exchange heat with the interior of the inner pot, and the first substance contained in the humidity control chamber can be vaporized under heating to increase the internal pressure of the humidity control chamber. Therefore, in the baking mode, when the temperature inside the inner pot rises to the set temperature, the push rod moves forward under the pressure difference between the front and rear to push the door body and form a dehumidification gap between the door body and the opening edge of the inner pot, thereby accelerating the dehumidification speed of the inner pot and improving the dehumidification effect.

[0035] The present invention is further described in detail below with reference to the accompanying drawings.

[0036] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0037] A steam oven, comprising: Figures 1 to 3The cooking liner structure shown comprises an inner liner 1 with an opening at the front side and a door body 2 for covering the opening of the inner liner 1. In this embodiment, the lower end of the door body 2 is hinged to the box body of the steam oven through hinges on the left and right sides (conventional setting mode, not shown).

[0038] Furthermore, it also includes Figures 4 to 7 The humidity control assembly shown includes a humidity control chamber 30 capable of heat exchange with the interior of the inner pot 1, a first substance (not shown) and a push rod 6. The first substance is contained in the humidity control chamber 30 and can be vaporized under heating to increase the internal pressure of the humidity control chamber 30. In this embodiment, specifically, the first substance is water, which is easy to realize and safe and reliable. When the temperature in the humidity control chamber 30 exceeds 100°C, the water vaporizes and increases the internal pressure of the humidity control chamber 30, thereby pushing the push rod 6 forward. When the temperature in the humidity control chamber 30 drops, the vaporized water re-liquefies and the internal pressure of the humidity control chamber 30 drops. In this way, in the steaming mode, the internal pressure of the humidity control chamber 30 does not change much, while in the baking mode, when the internal temperature of the inner pot 1 rises to above 100°C, the internal pressure of the humidity control chamber 30 changes greatly.

[0039] Furthermore, the push rod 6 is arranged along the front-to-back direction, and the rear end is penetrated through the through hole 31 of the wall of the humidity control chamber 30, while the front end is located outside the humidity control chamber 30 and can abut against the inner surface of the door body 2. In addition, in the initial state, the door body 2 covers the opening of the inner pot 1, and the front end of the push rod 6 is in contact with the inner surface of the door body 2 or has a front-to-back gap (preferably, the two are in front-to-back contact but the push rod 6 does not act on the inner surface of the door body 2); in the baking mode, when the temperature inside the inner pot 1 rises to the set temperature, the push rod 6 moves forward under the action of the front-to-back pressure difference to push the door body 2 and form a moisture-discharging gap (not shown) between the door body 2 and the opening edge of the inner pot 1.

[0040] In the present invention, the humidity control chamber 30 can exchange heat with the interior of the inner pot 1, and the first substance contained in the humidity control chamber 30 can be vaporized under heating to increase the internal pressure of the humidity control chamber 30. Therefore, in the roasting mode, when the temperature inside the inner pot 1 rises to the set temperature, the push rod 6 moves forward to push the door body 2 under the pressure difference between the front and rear to form a dehumidification gap between the door body 2 and the opening edge of the inner pot 1, thereby accelerating the dehumidification speed of the inner pot 1 and improving the dehumidification effect.

[0041] Furthermore, the humidity control chamber 30 is arranged outside the inner liner 1. The arrangement of the humidity control chamber 30 is convenient, and the internal volume of the inner liner 1 is not affected. Specifically, a block-shaped humidity control seat 3 is also included, and the humidity control seat 3 is attached to the outer surface of the inner liner 1, and the humidity control seat 3 is hollow to form the humidity control chamber 30. Thus, the structure of the humidity control chamber 30 can be well formed, and heat exchange between the humidity control chamber 30 and the inner liner 1 can be facilitated.

[0042] Furthermore, the above-mentioned humidity control seat 3 is attached to the outer surface of the upper front part of the inner pot 1, and the above-mentioned moisture removal gap is formed between the upper end of the door body 2 and the upper edge of the opening of the inner pot 1. On the one hand, the door body 2 of the cooking device is generally arranged to rotate up and down, so the above arrangement can extend the force arm of the push rod 6, thereby facilitating the push rod 6 to push open the door body 2; on the other hand, hot air has the characteristic of rising upward, and the moisture removal gap is arranged at the upper end to ensure the moisture removal effect. Preferably, the above-mentioned humidity control seat 3 is attached to the junction of the left side wall and the top wall of the inner pot 1, and the attachment surface 34 of the humidity control seat 3 connected to the inner pot 1 matches the outer surface of the inner pot 1 at that place. Thereby, the contact area between the humidity control seat 3 and the surface of the inner pot 1 can be increased, thereby improving the heat exchange efficiency between the humidity control cavity 30 and the inside of the inner pot 1, thereby improving the response speed of the push rod 6.

[0043] The specific structure of the humidity control seat 3 can be implemented in many ways. Preferably, the humidity control seat 3 is square in shape and is arranged horizontally, and its lower inner side is concave to form the arc-shaped mounting surface 34.

[0044] In addition, an upper mounting piece 35 is fixed on the inner side surface of the humidity control seat 3, and the upper mounting piece 35 is horizontally arranged on the top surface of the inner liner 1 and fixed to the first mounting seat 71 arranged on the top surface of the inner liner 1 through the first fastener 81, and a lower mounting piece 36 is fixed on the bottom surface of the humidity control seat 3, and the lower mounting piece 36 is vertically arranged outside the left side wall of the inner liner 1 and fixed to the second mounting seat 72 arranged on the outer side surface of the inner liner 1 through the second fastener 82. Thus, the humidity control seat 3 can better form the above-mentioned attachment surface 34, and at the same time, the humidity control seat 3 can be stably arranged on the inner liner 1.

[0045] Furthermore, the through hole 31 is provided on the front side wall of the humidity control seat 3, and the push rod 6 is sleeved with a reset spring 5. In the initial state, the reset spring 5 is in a naturally extended state, and when the internal temperature of the liner 1 rises to the set temperature, the reset spring 5 is compressed so that the push rod 6 has a tendency to move backward and reset, thereby realizing the automatic reset of the push rod 6. Specifically, the push rod 6 is cylindrical in shape and includes a mounting portion 61 at the rear end and a supporting portion 62 at the front end, the radius of the supporting portion 62 is smaller than that of the mounting portion 61, the mounting portion 61 is inserted into the through hole 31 and can move forward and backward relative to the edge of the through hole 31, and a clamping annular surface 63 is formed at the junction of the supporting portion 62 and the mounting portion 61. In addition, a mounting cover 4 extending forward and backward is provided on the front side of the humidity control seat 3 at the through hole 31, the push rod 6 is arranged in the mounting cover 4 along the central axis direction of the mounting cover 4, and a mounting hole 41 for the top holding portion 62 of the push rod 6 to pass through is provided on the front end wall of the mounting cover 4, and the reset spring 5 is clamped between the inner end surface of the mounting cover 4 and the clamping annular surface 63. Thus, the reset spring 5 can be stably arranged, and the push rod 6 can also be moved forward and backward smoothly.

[0046] Preferably, a mounting boss 33 is convexly provided on the front surface of the humidity control seat 3, the hole edge of the through hole 31 extends outwardly in the circumferential direction and penetrates the mounting boss 33 to form a guide channel 330, the mounting portion 61 of the push rod 6 is inserted in the guide channel 330 and can move back and forth along the guide channel 330, and the mounting cover 4 is covered on the mounting boss 33. In this way, the push rod 6 can move forward and backward more smoothly. Further preferably, a limit rod 32 is horizontally provided in the inner port of the guide channel 330, and in the initial state, the rear end of the push rod 6 is against the limit rod 32, so that the push rod 6 can be stably limited in the initial state. In addition, a door lining plate 11 is circumferentially provided outside the opening edge of the inner liner 1, and a guide hole 111 is provided on the door lining plate 11 for the front end of the push rod 6 to pass through and the size matches the front end of the push rod 6. On the one hand, the front end of the push rod 6 can smoothly abut against the inner surface of the door body 2 , and on the other hand, the push rod 6 can move forward and backward more smoothly through the guidance of the guide hole 111 .
