Description

Technical Field

[0001] The present invention relates to the technical field of steam ovens, and particularly to a residual water treatment device and a control method for a steam oven. Background Art

[0002] In the prior art, when using a steam oven to cook food, it is very easy to accumulate residual water, oil stains and food residues on the evaporation tray at the bottom of the inner cavity. If the user does not clean the evaporation tray at the bottom of the inner cavity in time, the mixture of food residues, oil stains and residual water will cause bacteria to grow on the evaporation tray, resulting in a taste mixing problem when cooking food next time. There is no device in the prior art steam oven to treat the residual water generated after cooking food. Although some steam oven cavities are provided with bottom heating devices at the bottom, they cannot effectively remove the residual water at the bottom of the inner cavity in time. Moreover, in order to reduce the residual water at the bottom of the steam oven, the cooking temperature of the steam oven can be increased. However, high-temperature cooking in the steam oven is extremely likely to cause deformation of the stainless steel inner liner, and the characteristic of stainless steel is that when it is at a relatively high temperature for a long time, the oxidation and yellowing of the stainless steel surface will be accelerated.

[0049] Embodiment 1

[0050] Aiming at the problems in the prior art that after the steaming oven finishes cooking, there will be residual water in the evaporation pan at the bottom of the steaming oven cavity, and the high-temperature cooking in the steaming oven will cause the inner liner of the steaming oven to deform or discolor, the present invention provides a residual water treatment device for the steaming oven to solve the above problems.

[0051] Specifically, as Figures 1-3As shown in the figure, the residual water treatment device provided by the present invention includes a heating plate 1 and a temperature measuring component. The upper side of the heating plate 1 is installed on the outer side of the bottom of the steaming box cavity 101. A heating element 2 is provided on the lower side of the heating plate 1. The heating element 2 is arranged around the center of the heating plate 1. This arrangement of the heating element 2 can increase the effective contact area between the heating element 2 and the bottom of the steaming box cavity 101, and can also make the bottom of the steaming box cavity 101 heat more evenly. The temperature measuring component includes a first temperature detecting element 3, a second temperature detecting element (not shown in the figure) and a third temperature detecting element (not shown in the figure). The first temperature detecting element 3 is installed on the lower side of the heating plate 1, and the detecting end of the first temperature detecting element 3 is placed between the center of the heating plate 1 and the heating element 2. A plurality of second temperature detecting elements are used to detect the temperatures at multiple positions on the heating plate 1. The third temperature detecting element is installed at a position corresponding to the center of the heating plate 1 on the bottom of the steaming box cavity 101.

[0052] In the residual water treatment device of the steaming box provided in this embodiment, the heating plate 1 is installed on the outer side of the bottom of the steaming box cavity 101. A heating element 2 is provided on the heating plate 1. The heating of the heating element 2 can effectively remove the condensed water accumulated in the evaporation pan 103 at the bottom of the steaming box cavity 101 during the operation of the steaming box, avoiding the breeding of bacteria in the steaming box cavity 101 caused by the mixing of accumulated water with oil and food residues, which affects the color, aroma, taste and nutrition of the cooked food in the steaming box cavity 101. Moreover, it can also assist the steam generator to generate enough steam for cooking food, making the steaming of the steaming box faster, and helping to lock in the nutrition of the food; the first temperature detecting element 3 and the second temperature detecting element are provided to detect the temperature of the heating plate 1. The first temperature detecting element 3 is arranged between the center of the heating plate 1 and the heating element 2, and can detect the average temperature of the heating plate 1. The second temperature detecting element is arranged at multiple positions on the heating plate 1 and can collect the temperatures at different positions of the heating plate 1. The third temperature detecting element is arranged at the bottom of the steaming box cavity 101 and corresponds to the center of the heating plate 1. The temperature detecting elements arranged at different positions provide multiple reference comparison values for the precise control of the temperature of the inner cavity of the steaming box, so as to realize the real-time detection of the temperature of the heating plate 1 while removing the residual water, avoiding the deformation or discoloration of the inner liner of the steaming box caused by the too high temperature of the inner cavity 101 of the steaming box, and extending the service life of the steaming box.

[0053] In this embodiment, the heating element 2 is evenly distributed on the heating plate 1 in a spiral shape. Preferably, the two ends of the heating element 2 are arranged close to each other. The spiral distribution of the heating element 2 further increases the effective contact area between the heating element 2 and the heating plate 1, making the bottom of the steaming chamber 101 heat more evenly. Further, the heating element 2 is disposed directly below the evaporation tray 103 in the steaming chamber 101, further improving the removal effect of the condensed water accumulated in the evaporation tray 103 at the bottom of the steaming chamber 101 during the operation of the steaming box. Still further, the heating element 2 coils around the center of the heating plate 1 for one circle, and one end of the heating element 2 is placed inside the other end of the heating element 2, so that the two ends of the heating element 2 overlap and are concentrically arranged, facilitating the simultaneous detection of whether the two ends of the heating element 2 can work properly.

[0054] In order to accurately measure the temperature of the heating plate 1, in this embodiment, as Figure 3 shown, the detection end of the first temperature detection element 3 is installed at the middle position between the heating element 2 and the center of the heating plate 1. The purpose is to ensure that the detection end of the first temperature detection element 3 is not too close to the heating element 2 to cause too high a detected temperature, nor too far from the heating element 2 to cause too low a detected temperature, thereby improving the accuracy of detecting the temperature of the heating plate 1. The temperature value detected by the first temperature detection element 3 will be displayed on the display screen of the steaming box for the user to monitor. Further, since the heating element 2 is distributed on the heating plate 1 in a spiral shape, in order to accurately collect the temperature of the heating plate 1, preferably, the first temperature detection element 3 is installed at the middle position between the inner circle of the heating element 2 and the center of the heating plate 1.

[0055] The waste water treatment device of the steaming box provided in this embodiment further includes a temperature limiter 4. The temperature limiter 4 can forcibly control the heating element 2 to turn off to ensure the safety of the heating element 2 during operation. Usually, in order to further improve the use safety of the waste water treatment device, two temperature limiters 4 are provided. One temperature limiter 4 is installed at the middle position between the heating element 2 and the center of the heating plate 1, and one temperature limiter 4 is installed between the two ends of the heating element 2. Since the space between the two ends of the heating element 2 is small, mounting plates are provided on the upper sides of the two ends of the heating element 2, and the temperature limiter 4 is installed on the mounting plates.

[0056] The setting of the installation position of the temperature limiter 4 provides a reference for the distribution of the second temperature detection elements. In this embodiment, it is preferably to set two second temperature detection elements, and one second temperature detection element is installed at each of the two temperature limiters 4. One of the second temperature detection elements will not be too close to the heating element 2 to cause the detected temperature to be too high, nor will it be too far from the heating element 2 to cause the detected temperature to be too low, which improves the accuracy of detecting the temperature of the heating plate 1. The other second temperature detection element can detect whether both ends of the heating element 2 can work properly. Therefore, in order to improve the detection accuracy and facilitate the detection, the two ends of the heating element 2 are arranged close to each other. The distribution of the two second temperature detection elements can detect the temperatures at different positions on the heating plate 1, improving the accuracy of the temperature detection of the heating plate 1. Preferably, the above-mentioned third temperature detection element and the second temperature detection element are both thermocouples.

[0057] Through the first temperature detection element 3, multiple second temperature detection elements and the third temperature detection element, the temperature of the heating plate 1 can be accurately detected from different positions, providing multiple reference comparison values for the accurate control of the temperature of the inner cavity of the steaming oven, and then accurately controlling whether the heating element 2 works, effectively avoiding problems such as deformation or discoloration of the inner cavity of the steaming oven due to too high temperature in the steaming oven cavity 101.

[0058] In this embodiment, the upper surface of the heating plate 1 is coated with thermal conductive silicone grease, and the thermal conductive silicone grease is evenly smeared on the surface of the heating plate 1. The heating plate 1 is fixed to the outer side of the bottom of the steaming oven cavity 101 with screws, which can ensure that the outer side of the bottom of the steaming oven cavity 101 is closely attached to the heating plate 1, enabling the heat dissipated by the heating element 2 to be fully transferred into the steaming oven cavity 101, improving the effect of the remaining water treatment at the bottom of the steaming oven cavity 101. In this embodiment, the material of the heating plate 1 is aluminum, which has good heat dissipation effect and improves the heating efficiency.

[0059] Embodiment Two

[0060] This embodiment provides a control method for the remaining water treatment device of a steaming oven, which is applied to the remaining water treatment device of the steaming oven provided in Embodiment One. As Figure 4 shown, the control method mainly includes: judging whether to start the heating element 2 according to the temperature detected by the first temperature detection element 3 and the temperature of the inner cavity 101 of the steaming oven; judging whether to turn off the heating element 2 according to the temperature detected by the first temperature detection element 3 or the temperature of the inner cavity 101 of the steaming oven or the temperature detected by any one of the second temperature detection elements. The control method provided in this embodiment judges whether to turn off the heating element 2 according to the temperature detected by the first temperature detection element 3 or the temperature of the inner cavity 101 of the steaming oven or the temperature detected by any one of the second temperature detection elements. After any one of the conditions is met, the heating element 2 can be turned off, ensuring that there is no remaining water on the evaporation tray 103 in the steaming oven after the steaming oven finishes cooking, and also preventing the temperature in the steaming oven from being too high to cause deformation or discoloration of the inner liner of the steaming oven, making the remaining water treatment device work more accurately and improving the user experience.

[0061] Figure 5 The following is a detailed step flowchart of the control method for the residual water treatment device of the steam box. The control method will be introduced in detail below in combination with Figure 5 this.

[0062] The control method for the residual water treatment device of the steam box includes the following steps:

[0063] Step 1: When the steam box starts and the heating element 2 starts to work, it is determined whether the temperature detected by the first temperature detection element 3 is greater than the seventh preset value. If so, the heating element 2 stops working.

[0064] Specifically, after the pre-operation of the steam box is completed, the heating element 2 starts to work and dry-heats the heating plate 1, so that the temperature in the steam box cavity 101 rises rapidly, improving the steaming efficiency of the steam box. However, in order to prevent the inner liner of the steam box cavity 101 from deforming or discoloring due to excessive temperature in the steam box cavity 101, the heating plate 1 stops heating after reaching a certain temperature. In this embodiment, when the temperature detected by the first temperature detection element 3 is greater than the seventh preset value, the heating element 2 stops working, achieving the purpose of dry-heating the heating plate 1. In practical applications, the fifth preset value is set according to the actual working parameters of the steam box. The seventh preset value in this embodiment can be set to 130 - 135 °C.

[0065] Step 2: It is determined whether the temperature detected by the first temperature detection element 3 is less than or equal to the first preset value and whether the temperature of the inner cavity 101 of the steam box is less than the second preset value. If so, the heating element 2 starts to work.

[0066] Specifically, after the heating element 2 stops working, the steam generator of the steam box continues to work and generates steam to steam food. At this time, water vapor will be generated in the cavity of the steam box, and the water vapor will condense into water when it falls on the evaporation tray 103 at the bottom of the steam box cavity 101, and the condensed water has a certain cooling effect. When there is a large amount of condensed water at the bottom of the steam box cavity 101, the temperature of the heating plate 1 will decrease. Therefore, the first temperature detection element 3 is required to collect the temperature value of the heating plate 1 in real time. At the same time, the temperature sensor 102 provided in the inner cavity 101 of the steam box is also required to collect the temperature of the inner cavity 101 of the steam box in real time (refer to Figure 6 ), and the heating element 2 can only heat when the temperature of the inner cavity 101 of the steam box and the temperature of the heating plate 1 meet the requirements, effectively avoiding excessive water accumulation at the bottom of the steam box cavity 101 and excessive temperature in the inner cavity 101 of the steam box, and realizing precise control of the operation of the heating element 2.

[0067] In this embodiment, when the temperature detected by the first temperature detector 3 is less than or equal to the first preset value and the temperature of the inner cavity 101 of the steam box is less than the second preset value, it proves that there is accumulated water in the evaporation tray 103 at the bottom of the inner cavity 101 of the steam box, and the temperature of the inner cavity 101 of the steam box is not very high. Then, the heating element 2 is started to heat, so that the accumulated water evaporates to generate water vapor, which can not only remove the accumulated water but also assist in steaming food, improving the working efficiency of the steam box. In this embodiment, the first preset value is preferably set to 100-105 °C, and the second preset value is preferably set to the cooking temperature of the steam box set by the user + (1 °C - 3 °C).

[0068] Step 3: Determine whether the temperature detected by the first temperature detector 3 is greater than the third preset value, or whether the temperature of the inner cavity 101 of the steam box is greater than or equal to the fourth preset value, or whether the temperature detected by any one of the second temperature detectors is greater than the temperature control value of the thermostat. If so, the heating element 2 stops working.

[0069] Specifically, after the heating element 2 is restarted to heat in Step 2, it is also necessary to continuously detect the temperature of the heating plate 1 and the temperature of the inner cavity 101 of the steam box in real time to ensure that the temperature of the inner cavity 101 of the steam box does not become too high while removing the accumulated water. In this embodiment, the first temperature detector 3 and the second temperature detectors collect the temperature of the heating plate 1, and the temperature sensor 102 in the steam box collects the temperature of the inner cavity 101 of the steam box. When the temperature detected by the first temperature detector 3 is greater than the third preset value, or the temperature of the inner cavity 101 of the steam box is greater than the fourth preset value, or the temperature detected by any one of the second temperature detectors is greater than the temperature control value of the thermostat, as long as one of the conditions is met, the heating element 2 stops heating.

[0070] When the value calculated from the temperature detected by the first temperature detector 3 and the temperatures detected by the two second temperature detectors is greater than the fourth preset value, the thermostat 4 will force the heating element 2 to continue heating, causing the heating element 2 to stop working, ensuring the safety of using the steam box. Using the values calculated from the temperature values at four different detection positions to judge the temperature of the heating plate 1 has high accuracy. While avoiding the generation of accumulated water at the bottom of the inner cavity 101 of the steam box, it also prevents dry burning. When the temperature of the inner cavity 101 of the steam box is greater than the second preset value, it means that the temperature of the inner cavity 101 of the steam box is too high, and the heating element 2 needs to be turned off. In this embodiment, three judgment conditions are used to control whether the heating element 2 is turned off, which can ensure that there is no accumulated water inside the steam box after cooking and can accurately control the temperature of the inner cavity 101 of the steam box so as not to affect the components inside the steam box due to excessive temperature. In this embodiment, the third preset value is set to 130-135 °C, and the fourth preset value is set to the cooking temperature of the steam box set by the user + (1 °C - 3 °C).

[0071] Among them, the temperature control value of the thermostat is the maximum value between the average value of the temperatures detected by the two second temperature detectors and the average value of the temperatures detected by the first temperature detector 3 and the third temperature detector during different heating stages. During the operation of the steaming box, when the temperature detected by any one of the second temperature detectors is greater than the above maximum value, the thermostat 4 forces the heating element 2 to stop working. The thermostat 4 has a protection function, which improves the safety of using the steaming box.

[0072] Specifically, when the temperature detected by the first temperature detector 3 reaches the fifth preset value, the temperatures detected by the two second temperature detectors are t1 and t2 respectively, and the temperature detected by the third temperature detector is t3; when the temperature detected by the third temperature detector reaches the sixth preset value, the temperatures detected by the two second temperature detectors are t4 and t5 respectively, and the temperature detected by the first temperature detector is t6; the average values of t1 and t4, t2 and t5, and t3 and t6 are taken to obtain T1, T2, and T3 respectively, and the maximum value among T1, T2, and T3 is the temperature control value of the thermostat. Among them, the fifth preset value is 130°C, and the sixth preset value is 200°C. Since the temperature collected by the third temperature detector is higher than the temperatures detected by the first temperature detector 3 and the second temperature detectors, in order to ensure the safety of using the steaming box, when the temperature detected by the third temperature detector reaches the sixth preset value, the temperatures collected by other temperature detectors are collected as reference comparison values, and the data collected twice are averaged as the reference comparison value, which improves the accuracy of data comparison, can accurately control the closing of the heating tube, prevent the temperature in the steaming box from being too high, and can also make there be no remaining water at the bottom of the steaming box cavity 101.

[0073] In this step, if the heating element 2 meets the condition for shutting down, the heating element 2 stops working, and then step two is executed, and this cycle continues until the steaming of the steaming box is completed.

[0074] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
