Description

Heating cooking device

Technical Field

The present invention relates to the field of household appliances, in particular to a heating and cooking device.

Background

With the development of technology, people's lives are becoming increasingly busy, and demands for cooking automation are increasing, and in order to perform automatic cooking more and more, various detectors are installed in more and more cooking appliances.

For example, the cooking device can perform cooking suitable for a menu selected by a user by using temperature values or temperature changes such as a temperature of food and a temperature rise degree in a heating chamber, by using a weight detector to obtain a weight of the food, and by using a weight detector to detect an amount of steam emitted from the food during heating.

In particular, in a microwave oven, since food is heated by microwaves generated from a magnetron, heating time, heating intensity, and the like can be controlled relatively accurately. In order to implement more menu functions, various detectors are provided in the microwave oven.

In recent years, an infrared detector is generally provided in a microwave oven, and thus a detection hole is required to be provided in a heating chamber through which infrared rays are transmitted to the infrared detector. However, dew condensation formed by steam generated by heating in the heating chamber may pass through the detection hole to contaminate the lens serving as the detection portion of the infrared detector.

In a microwave oven equipped with a heater, a hole such as an exhaust port or a gap is usually provided to allow heat to be exhausted. Although the object to be heated is often covered with a film or a cover, if the user carelessly puts the article covered with the case into a microwave oven to be heated, or puts the sealed article into a microwave oven to be heated, a large crack is likely to occur, and the heating chamber is likely to be filled with the residue.

The user can clean the wall surface in the heating chamber, but it is difficult to clean the inside of the hole such as the exhaust port or the intake port provided in the heating chamber. The detection holes used in the infrared detector are also difficult to clean, as are the holes.

In addition, the detection hole is generally opened to be large in order to allow the detection infrared ray to pass smoothly. Since the hole for infrared detection has a larger diameter than the diameter of the exhaust port, the intake port, and the like, the possibility of food flying debris and the like entering the hole increases when food is suddenly scattered due to overheating and the like.

In order to prevent heat generated in the heating chamber and scattered matter such as food scraps and dew drops from contaminating the infrared detector, it is known to protect the infrared light receiving unit with a shielding plate or the like. When the device is used, the shielding plate is opened, so that the object to be measured in the heating chamber can be observed through the detection hole, and the shielding plate is closed at other time, thereby preventing scattered objects from entering the infrared detector through the detection hole to pollute the lens.

in addition, the following technical solutions are also disclosed in the prior art: an air guide duct is provided in front of the fan, and part of the air for electric cooling of the fan flows to the infrared detector. However, since the wind is easily diffused in the electric room during the diversion process, the flow of the scattered matter such as food scraps and dew drops cannot be effectively suppressed. Therefore, the contamination of the lens portion of the infrared detector is becoming serious with the use of the microwave oven, and the sensitivity of detection is decreasing.

Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, the use of directional words such as "upper, lower, left and right" generally means upper, lower, left and right as viewed with reference to the accompanying drawings; "inner and outer" refer to the inner and outer relative to the profile of the components themselves. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

The invention provides a heating cooking device, comprising a heating chamber 10 for accommodating food to be heated; a heating unit 20 for heating food placed in the heating chamber 10; a detection unit 30 for detecting the state of the food in the heating chamber 10; a detector fixing stand 40 for fixing the detecting unit 30 to the heating chamber 10, and a fan 60.

As shown in fig. 1 to 6, the fan 60 used in the heating cooking apparatus of the present invention can generate a straight blowing side blow with the detector fixing stand 40 on the downwind direction side of the side blow. By forming the air passage 51 and the air port hole 52 communicating with the air passage 51 in the detector fixing base 40, the side-blown air passes through the air passage 51 and the air port hole 52 to form a rectified air having a direction intersecting the penetration direction of the detection hole 16 of the detection unit 30.

It is easily understood that the fan 60 used in the present invention, when rotated, is blown in a direction perpendicular to the rotating shaft 64, in addition to the forward direction, i.e., perpendicular to the rotating shaft 64, and also blown downward, upward, leftward, and rightward, i.e., perpendicular to the rotating shaft 64 of the fan 60. Also, since the wind generated by the fan 60 has a certain divergence, the parallel and perpendicular directions described in the present invention describe a general flow direction of the wind.

Further, since the plurality of blades of the fan 60 are provided so as to stand up relative to each other, and the detection unit 30 is horizontal to the blades as viewed from the top F of fig. 1, the detector fixing base 40 provided in the horizontal direction to the fan blades can block the passage of the contaminants to the detection unit by the wind.

According to the present invention, the structure of the detector fixing base 40 allows the wind generated by the fan 60 to enter the vicinity of the mounting surface of the detector unit 30, and the cross-flow wind entering the detector fixing base 40 passes through the wind path 51 to form the rectified wind, the wind force is enhanced, and the wind can pass through the wind opening 52 in front of the wind path 51 of the detector fixing table 40, the air port hole 52 is communicated with the air passage 51, and the rectified wind smoothly flows through the detector fixing base 40, and the formed rectified wind flows along the inner surface of the detector fixing base 40 (i.e., the surface facing the fixing surface described below), the wind direction of the detection unit 30 intersects with the penetrating direction of the detection hole 16, so that the scattered matters such as food flying slag and dew drops generated in the heating process can be prevented from entering the detector from the detection hole 16, the lenses and the like in the detection unit 30 are contaminated, so that the detection unit 30 can maintain stable detection accuracy for a longer time.

As a specific embodiment, as shown in fig. 3, the heating chamber 10 includes a bottom plate 11, a left side plate 12 and a right side plate 13 connected to the bottom plate 11, an exhaust hole 14 is provided on one of the left side plate 12 and the right side plate 13, and an intake hole 15 and a detection hole 16 are provided on the other of the left side plate 12 and the right side plate 13. In order to obtain the state change of the food during the heating process, the detection unit 30 needs to be able to always obtain the state in the heating chamber 10 through the detection hole 16, and therefore the detection hole 16 needs to be able to always communicate with the inside of the heating chamber 10.

As shown in fig. 3, the diameter of the detection hole 16 is generally larger than the diameters of the exhaust hole 14 and the intake hole 15, and therefore, water drops during heating or contaminants such as food debris generated by irregular operation or excessive heating are more likely to enter the detection hole 16. Although the detection hole 16 is covered with a shield cover or the like, entry of contaminants can be avoided during shielding. However, when the detection unit 30 is required to perform detection, the shielding cover needs to be opened, and at this time, contaminants can still enter through the detection hole 16.

With the structure of the detector fixing stand 40 of the present invention, a rectified wind intersecting the penetrating direction of the detection hole 16 of the detection unit 30 can be formed. The rectified wind can form enough wind pressure at the detection hole 16 during the detection of the detection unit 30, and force the pollutant not to pass through the detection hole 16, so that the pollutant can be effectively prevented from entering the detection hole 16 in the whole heating process and even in a certain time after heating.

As shown in fig. 4 to 6, the detector fixing base 40 has a first fixing portion 48 and a second fixing portion 49 that can be fixed to a fixing surface (i.e., the right side surface 13), and the detector fixing base 40 is preferably disposed above the fan 60 by the first fixing portion 48 and the second fixing portion 49. Specifically, the air passage 51 can be formed by the first wall portion 46 disposed between the first fixing portion 48 and the second fixing portion 49, and the fixing side plate 45 for fixing the detection unit 30. That is, the air passage 51 is formed by forcing the side-blow air to flow through the gap formed between the first wall portion 46, the fixed side plate 45, and the fixed surface.

In addition, in order to guide the flow of the side blow air without causing the side blow air to form a turbulent flow in the gap, the air inlet hole 52 may be formed in the vicinity of the fixing surface of the fixing side plate 45. The air inlet hole 52 is preferably provided near the detector 31 so that the cross-wind flows more easily, and effectively forms a blocking flow between the detector 16 and the detector 31, that is, a flow direction of the cross-wind flowing along the air passage 51 is orthogonal to a penetrating direction of the detector 16, thereby blocking a passage of contaminants to the detector.

Further, it is preferable that the detector fixing table 40 further has a second wall portion 47, the second wall portion 47 being located between the first wall portion 46 and the fixing side plate 45 and being parallel to the first wall portion 46, the strength of the rectified wind entering the detector fixing table 40 can be increased by the second wall portion 47, and the flow rate of the cross wind flowing toward the detection section 31 can be brought by rectifying the side wind by the first wall portion 46 and the second wall portion 47 which are parallel to each other. Further, a plurality of second wall portions 47 may be provided according to the width of the detector fixing base 40 and the fan 60.

Specifically, the top portion 44 is connected between the second wall portion 47 and the first wall portion 46, the fixed side plate 45 is inclined with respect to the second wall portion 47 and is connected to the second wall portion 47 at an acute angle, and the air inlet hole 52 includes a top air inlet hole 521 provided in the top portion 44, and a first air inlet hole 522 and a second air inlet hole 523 provided in the fixed side plate 45. The first and second tuyere holes 522 and 523 are arc holes.

The fixed side plate 45 is provided with a gap support 41 so that a first gap 531 is defined between the fixed side plate 45, the second wall portion 47 and the fixed surface. The gap support 41 is preferably formed in an L-shape, that is, a passage is opened in a portion facing the detection unit 31.

As shown in fig. 5, in which the air passage 51 is indicated by an arrow, the first gap 531 has a lower opening, and the lower opening is preferably positioned above the fan 60. With this arrangement, the first air passage 511 is formed by the fixed side plate 45, the gap support portion 41, the second wall portion 47, the first air port hole 522, the second air port hole 523, and the fixed surface, and the rectified air flowing through the first air passage 511 enters from the lower opening of the first gap 531, flows through the fixed side plate 45, and flows out from the first air port hole 522 and the second air port hole 523. Similarly, the second duct 512 enters from the lower opening of the second gap 532, passes through the fixed surface, and flows out from the top tuyere hole 521.

In order to allow as much cross-wind as possible to enter the detector fixing base 40 and form a rectified wind, as shown in fig. 6, the detector fixing base 40 further includes a guide portion 43, and the guide portion 43 is connected between the first wall portion 47 and the second wall portion 46 and is connected to the ceiling portion 44. The guide portion 43 can guide the side blowing air by making a lower opening of a second gap 532 described below large and inclining the second mounting portion 49 (fixing surface) from below, thereby effectively preventing the air from spreading, making the air flowing through the detection hole 16 have sufficient air pressure, and preventing scattered matters such as food flying slag and dew drops from contaminating the detection portion 31 through the detection hole 16. As shown in fig. 4, a side plate hole 42 may be provided on the outer side surface of the second wall portion 46, and the side plate hole 42 may be used to fix the detection unit housing case 70. The detection unit housing case 70 is provided with corresponding fixing holes, and the detection unit housing case 70 is fixed to the detector fixing base 40 by fasteners such as bolts.

With the above configuration, as shown by the arrow in fig. 6, the top portion 44, the second wall portion 47, the first wall portion 46, and the fixing surface are engaged with the guide portion 43, so that the air passage 512 can be formed by the enclosed second gap 532. That is, the second gap 532 has a lower opening which is located above the fan 60, and the wind of the fan 60 can enter along the guide portion 43, join with the wind indicated by the arrow in fig. 5, form a strong wind force, and intersect with the penetrating direction of the detection hole 16, thereby reliably preventing the scattered matters such as food flying slag, dew drops, and the like from entering the detection unit 30 from the detection hole 16, so that the detection unit 30 can maintain stable detection accuracy for a long time.

In the present invention, it is preferable that a bracket fan including a fan blade portion 61, a fan guide 62 for fixing the fan blade portion 61, and a fan suspension 63 is used as the fan 60, and the detector fixing base 40 is disposed in contact with the fan guide 62, so that the air blown to the fan guide 62 can be made to flow along the fan guide 62 into the air passage 51 of the detector fixing base 40, thereby further improving the wind force. And the fan guide plate 62 can prevent the wind from spreading.

Specifically, the detecting unit 30 is an infrared detecting device which is mounted on the detector fixing table 40 through the accommodating case 70 of the detecting unit 30, and the accommodating case 70 of the detecting unit 30 and the detector fixing table 40 are each provided with an infrared hole so that infrared rays transmitted and received by the detecting portion 31 of the infrared detecting device can pass through the detecting hole 16 and enter and exit the heating chamber 10.

As shown in fig. 1-2, the heating cooking device is a microwave oven, the heating unit 20 includes a magnetron device 22 for generating microwaves, and a power supply 21 for supplying power to the magnetron device 22, the heating unit 20 is disposed in front of a straight air blower, and the detector fixing stand 40 is disposed in front of a side air blower.

The heating chamber 10 is surrounded by a bottom plate 11, left and right side plates 12 and 13 connected to the bottom plate 11, a top plate 17, and a door 19 hinged to the bottom plate 11 to be opened and closed, and a magnetron device 22 is provided outside the heating chamber 10.

Specifically, when food is heated by a microwave oven, the power supply 21 supplies power to apply a high voltage to the magnetron device 22 in order to radiate microwaves in the heating chamber 10. Thereby, the food placed in the heating chamber 10 starts to absorb the microwave. At the same time, the fan 60 for cooling the power supply 21, the magnetron device 22, and other electric components starts to operate, and starts to blow air to each part.

According to the present invention, the infrared detection device provided in the direction substantially perpendicular to the fan 60 is provided by the detection unit 30 housing case 70 and the detector fixing stand 40. The fan 60 can blow not only in the forward direction but also a straight blow by the rotational movement. The fan 60 can also blow air to the surroundings, and the fan guide 62 provided in a substantially horizontal direction allows the substantially horizontal air to reach the detection unit 30 of the infrared detection device, the housing case 70, and the detector fixing base 40. Since the inner surface of detector fixing base 40 to which detection unit 30 is fixed in housing case 70 has a gap, that is, includes first gap 531 and second gap 532, the flow of air generated by fan 60 can be rectified by providing a plurality of walls parallel to the direction of the air, that is, first wall 47 and second wall 46.

As is apparent from the above description, the detector fixing stand 40 of the present invention is constructed and installed in such a manner that the wind generated from the fan 60 can effectively reach the vicinity of the installation surface of the infrared ray detection device as the detection unit 30, not only effectively preventing the wind from spreading, the wind is effectively rectified to enhance the wind force, the side blow of the fan 60 smoothly flows through the first air passage 511 and the first air passage 512, and by providing the air outlet holes (the ceiling air outlet hole 521, the first air outlet hole 522 and the second air outlet hole 523, so that the cross-wind flows more easily to the air flow of the fan 60 for cooling the electric parts, scattered matters such as food flying residues and dew drops are effectively prevented from polluting the lens and the like of the detector 31 in the whole process of heating the food, so that the detection unit 30 can keep stable detection precision for a long time.

The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, numerous simple modifications can be made to the technical solution of the invention, including combinations of the specific features in any suitable way, and the invention will not be further described in relation to the various possible combinations in order to avoid unnecessary repetition. Such simple modifications and combinations should be considered within the scope of the present disclosure as well.
