Technical Field

[0002] Cooking equipment (such as steamers and ovens) typically requires maintaining a high steam density during operation. Existing technologies typically use humidity sensors to detect the steam density within the cooking device cavity and feed this density back to the control system for temperature and water level control. However, humidity sensors have a narrow detection range and can only measure relative humidity when the steam density is not saturated. They cannot detect steam density at saturated humidity, which affects the taste of the food. Furthermore, humidity sensors are installed inside the cooking device cavity, where they are exposed to high temperatures and high humidity for extended periods, resulting in a short service life. Therefore, designing a steam density detection device with a wide detection range and a long service life is particularly important. Utility Model Content

[0033] For cooking equipment that utilizes steam, such as steamers and ovens, it is necessary to detect the steam density inside the cooking equipment and adjust the temperature and water level of the cooking equipment based on the steam density detection results to ensure the normal operation of the cooking equipment. Typically, a humidity sensor is used to detect the steam density of the cooking equipment. However, the humidity sensor has a small detection range and can only measure the relative humidity when the steam density is not saturated. It cannot detect the steam density at saturated humidity, which affects the taste of the cooking. In addition, the humidity sensor is installed inside the cavity of the cooking equipment and is exposed to high temperature and high humidity for a long time, resulting in a short service life. To this end, the embodiments of the present application provide a steam density detection device, a control system, and a cooking device for cooking equipment.

[0034] See Figure 1 On the one hand, the utility model discloses a steam density detection device for a cooking device, which is arranged outside the cavity of the cooking device; the steam density detection device includes a steam density calculation device 1, a steam density detection light emitting device 2 and a steam density detection light receiving device 3; the steam density calculation device 1 is electrically connected to the steam density detection light emitting device 2 and the steam density detection light receiving device 3 respectively; the steam density calculation device 1 includes a steam density calculation module 13, a detection light control module 11 and an electric signal acquisition module 12; the steam density calculation module 13 is electrically connected to the detection light control module 11 and the electric signal acquisition module 12 respectively; the detection light control module 11 is electrically connected to the steam density detection light emitting device 2, and the electric signal acquisition module 12 is electrically connected to the steam density detection light receiving device 3; the steam density detection light receiving device 3 includes a photoelectric signal conversion module 31 and a steam density detection light receiving module 32; the photoelectric signal conversion module 31 is electrically connected to the electric signal acquisition module 12 and the steam density detection light receiving module 32 respectively.

[0035] Optionally, the cooking equipment includes but is not limited to a steamer, a steam oven, etc.

[0036] For example, Figure 2 As shown, the steam density detection device is arranged outside the cavity of the cooking equipment, thereby avoiding direct contact between the steam density detection device and the steam density, avoiding the steam density detection device from working in a high temperature and high humidity environment, extending the service life of the steam density detection device, and ensuring food safety.

[0037] It should be noted that Figure 2 Only part of the structure of the steam density detection device is shown.

[0038] For example, Figure 1As shown, the steam density detection device includes a steam density calculation device 1, a steam density detection light emitting device 2, and a steam density detection light receiving device 3. The steam density calculation device 1 is electrically connected to the steam density detection light emitting device 2 and the steam density detection light receiving device 3. The steam density detection device is used to complete steam density detection inside the cavity of the cooking device.

[0039] Illustratively, the steam density detection light emitting device 2 is used to emit detection light into the cavity of the cooking device under the drive of the detection light control module 11 in the steam density calculation device 1. After the detection light propagates inside the cavity of the cooking device, it will be partially absorbed by water vapor and small droplets.

[0040] Optionally, the detection light intensity includes light of multiple wavelength bands, the steam density detection light emitting device 2 and the detection light control module 11 are electrically connected, and the detection light control module is further used to select a specific wavelength band of the detection light.

[0041] Illustratively, the steam density detection light receiving device 3 includes a photoelectric signal conversion module 31 and a steam density detection light receiving module 32. The steam density detection light receiving module 32 is configured to receive the detection light that has passed through the cavity of the cooking device and been partially absorbed. The photoelectric signal conversion module 31 then converts the received light signal into an electrical signal.

[0042] Exemplarily, the photoelectric signal conversion module 31 is electrically connected to the electrical signal acquisition module 12 in the steam density calculation device 1, and is used to transmit the electrical signal to the electrical signal acquisition module, so that the steam density calculation module 13 completes the calculation of the steam density based on the detection light emitted by the steam density detection light emitting device 2 and the detection light re-received by the steam density detection light receiving module 3.

[0043] Alternatively, the absorption of the probe light by water vapor and liquid droplets follows the Beer-Lambert law:

[0044]

[0045] Wherein, I represents the detection light intensity re-received by the vapor density detection light receiving module 3, I0 represents the detection light intensity, K represents the absorption coefficient, b represents the optical path, and c represents the vapor density concentration.

[0046] In the above formula, the detection light intensity and the detection light intensity re-received by the steam density detection light receiving module 3 are based on values obtainable by the steam density calculation device 1. The optical path b is the fixed light transmission path selected during the manufacturing of the cooking device. The absorption coefficient K can be calibrated and adjusted based on temperature and air pressure. Therefore, the steam density calculation module 13 can calculate the steam density according to the Beer-Lambert law.

[0047] The embodiment of the present invention realizes contactless testing of the steam density of the cooking device by arranging a steam density detection device outside the cavity of the cooking device, so that the device has the advantages that the steam density testing process does not affect the safety of the cooking device body and food and has a long service life; by electrically connecting the steam density calculation device to the steam density detection light emitting device and the steam density detection light receiving device respectively, a steam density calculation module, a detection light control module and an electrical signal acquisition module are provided in the steam density calculation device, and a photoelectric signal conversion module and a steam density detection light receiving module are provided in the steam density detection light receiving device, it is realized that the detection light emitting device is used to emit detection light into the cavity of the cooking device, and the steam density detection light receiving device is used to receive the detection light carrying steam density and convert the optical signal into an electrical signal, so that the steam density calculation device calculates the steam density inside the cavity of the cooking device according to the electrical signal. The device can be used to detect unsaturated steam and the steam density of saturated steam, and has the advantages of a large detection range and high accuracy.

[0048] In some embodiments, the steam density detection light emitting device 2 includes a preset number of independent light sources 21 , and the preset number of independent light sources 21 are electrically connected to the detection light control module 11 .

[0049] In some embodiments, the preset number of independent light sources 21 includes a preset number of detection light sources and a preset number of reference light sources.

[0050] Exemplarily, the steam density detection light emitting device 2 includes a preset number of independent light sources 21. Each independent light source 21 works independently without interfering with each other, thereby ensuring the stability of the light source and the stability of the test. The preset number of independent light sources 21 includes a preset number of detection light sources and a preset number of reference light sources.

[0051] Optionally, the principle for selecting the detection light source is a light source that can be absorbed by water vapor or small droplets, and the detection light source is used to emit detection light.

[0052] Optionally, the reference light source is selected to emit reference light in a light range that is not absorbed by water vapor and small droplets. Normally, the reference light is not absorbed by the light range absorbed by water vapor and small droplets. However, if the reference light experiences light loss before or after passing through the cooking device cavity, the steam density calculation process can be calibrated based on the light loss of the reference light.

[0053] Optionally, the detection light source is infrared light and visible light, preferably near-infrared light with two waveguides of 1.1 um and 1.4 um.

[0054] Optionally, the reference light source is infrared light and visible light.

[0055] This embodiment of the utility model incorporates a predetermined number of independent detection and reference light sources within the steam density detection device. These independent light sources do not interfere with each other, improving the stability of the light sources and the stability of the steam density test. By utilizing the principle of light absorption by water vapor, the steam density detection device can detect not only unsaturated steam but also the density of saturated steam, offering the advantages of a wide detection range and high accuracy. Furthermore, the predetermined number of independent light sources are positioned outside the cooking cavity, enabling contactless testing of the steam density of the cooking device. This ensures that the steam density test process does not affect the safety of the cooking device itself or food, and provides a long service life.

[0056] In some embodiments, as Figure 2 As shown, a lens 4 and a light-transmitting window 5 are provided on the detection light propagation path 3 between the steam density detection light emitting device 2 and the steam density detection light receiving device.

[0057] For example, to improve the propagation effect of the detection light, a lens 4 and a light-transmitting window 5 are provided on the detection light propagation path between the steam density detection light emitting device 2 and the steam density detection light receiving device 3. The lens 4 is used to transmit the detection light through the light-transmitting window 5 into the interior of the cooking device cavity. It is also used to transmit the detection light that has passed through the cooking device to the steam density detection light receiving module 32. The light-transmitting window is used to allow the detection light to enter and exit the interior of the cooking device cavity through the light-transmitting window 5.

[0061] Exemplarily, the lens 4 includes a transmitting lens 41 and a receiving lens 42. A light-transmitting window 5 is disposed between the transmitting lens 41 and the receiving lens 42. The light-transmitting window 5 includes a first light-transmitting window 51 and a second light-transmitting window 52. The transmitting lens 41 is configured to transmit detection light through the first light-transmitting window 51 into the interior of the cooking device cavity, while the receiving lens 42 is configured to transmit the detection light passing through the cooking device to the steam density detection light receiving module 32. The transmitting lens 41 is disposed on one side of the exterior of the cooking device cavity, while the receiving lens 42 is disposed on the other side of the exterior of the cooking device cavity. Furthermore, the first light-transmitting window 51 and the second light-transmitting window 52 are disposed on the surface of the cooking device cavity to allow the detection light to enter and exit the interior of the cooking device cavity.

Figure 2 As shown by the middle dotted line, the detection light emitted by the steam density detection light emitting device 2 passes through the emitting lens 41, the first light-transmitting window 51, the inside of the cooking equipment cavity, the second light-transmitting window 52, and the receiving lens 42 in sequence, and is finally received by the steam density detection light receiving module 32 in the steam density detection light receiving device 3, and is converted into an electrical signal by the photoelectric conversion module 31 for steam density calculation.

Specifically, the steam density detection light emitting device 2 and the steam density detection light receiving device 3, and the number of light-transmitting windows 5 can be two or three, and a first light-transmitting window 51 is set on the same side as the steam density detection light emitting device 2, and a second light-transmitting window 52 is set on the other side. At this time, the detection light emitted by the steam density detection light emitting device 2 passes through the emitting lens 41, the first light-transmitting window 51, the inside of the cooking device cavity, the second light-transmitting window 52 in sequence, and is then emitted by the receiving lens 42 and passes through the first light-transmitting window 51 again, and is finally received by the steam density detection light receiving module 32 in the steam density detection light receiving device 3, and is converted into an electrical signal by the photoelectric conversion module 31 for steam density calculation.

[0065] The embodiment of the utility model improves the stability of the light source and the stability of the steam density test by arranging an emitting lens, a receiving lens and a light-transmitting window in the steam density detection device to realize the propagation of the detection light.
