Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a high-temperature steam test operation method for a cooking device and a cooking device. Background Art

[0002] Before the steam cooking product is completed in the factory, it is necessary to conduct a high-temperature steam inspection on the steam pipeline of the steaming function to prevent problems such as steam pipeline air leakage and poor inner tank sealing.

[0003] Most of the existing products turn on the steaming function to generate steam and then observe whether there is air leakage in the whole machine. After the inspection, the remaining water in the cooking cavity is drained, and the water stains in the cooking inner tank are wiped clean with a water-absorbing sponge, and then compressed air is used to dry the water stains inside the cooking cavity.

[0004] In order to make the cavity wall of the cooking cavity of the steam cooking product easier to clean, a glass plate assembly is used to block the upper heating tube on the top side to prevent oil stains from adhering to the upper heating tube during cooking, so that users do not need to clean the oil stains on the upper heating tube. However, the upper heating tube accommodation cavity formed by enclosing between the glass assembly and the top side of the cooking cavity will be filled with a large amount of high-temperature steam during the steam inspection. After the high-temperature steam inspection is completed, the high-temperature steam will condense into water and accumulate in the upper heating tube accommodation cavity, resulting in difficult cleaning of the condensed water.

[0005] Therefore, there is an urgent need for a high-temperature steam test operation method for a cooking device to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve at least one of the problems existing in the related art to a certain extent. For this purpose, the present invention provides a high-temperature steam test operation method for a cooking device. When performing the airtightness test of the cooking device, the upper heating tube is controlled to operate to heat the heating tube accommodation cavity, so that the high-temperature steam provided by the evaporator is vaporized at high temperature when entering the heating tube accommodation cavity, avoiding the condensation of the high-temperature steam into liquid water in the heating tube accommodation cavity. Thus, after the test is completed, it is not necessary to disassemble the top plate shielding assembly to clean the condensed water in the heating tube accommodation cavity, improving the test efficiency.

[0039] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed by the present invention.

[0040] Please refer to Figures 1-4 The present invention provides a high-temperature steam test operation method for a cooking device, wherein the cooking device comprises a cooking cavity 1, an evaporation component arranged outside the cooking cavity 1 and connected to the cooking cavity 1, and a side heating pipe and an upper heating pipe 2 arranged in the cooking cavity 1, wherein the evaporation component comprises an evaporator (not shown in the figure) and a water pump (not shown in the figure), wherein a top plate shielding component 4 is arranged on the top side of the cooking cavity 1, wherein a heating pipe accommodating cavity is formed between the top plate shielding component 4 and the top side of the cooking cavity 1, wherein an upper heating pipe 2 is arranged in the heating pipe accommodating cavity, and the high-temperature steam test operation method for the cooking device comprises the following steps:

[0041] S1: Turn on the upper heating tube 2, the side heating tube and the evaporator, and the upper heating tube 2, the side heating tube and the evaporator operate according to the preheating stage program (this stage lasts about 3 minutes);

[0042] S2: Determine whether T1>T2. If so, turn off the side heating tube, and the upper heating tube 2 runs according to the pre-cooking stage program and enters S3 (this stage lasts about 5 minutes). If not, repeat S2;

[0043] S3: Determine whether T1>T3. If so, turn off the upper heating pipe 2, vaporize the high-temperature steam by preheating the heat pipe chamber, and facilitate cooling of the heat pipe chamber in subsequent steps. The evaporator runs according to the cooking stage program (this stage lasts about 5 minutes to 10 minutes) and enters S4. If not, repeat S3.

[0044] S4: After cooking is finished, the evaporator is turned off, and the water pump is turned on to pump the condensed water in the cooking chamber 1 and the remaining water in the high-temperature steam delivery pipe to the evaporator;

[0045] S5: The evaporator enters the dry-burning stage to evaporate the remaining water in the evaporator;

[0046] S6: Determine whether the dry-burning stage is completed. If so, turn off the evaporator and the test program ends. If not, repeat S6;

[0047] Wherein: T1 is the real-time temperature in the cooking cavity 1, T2 is the first preset temperature, T3 is the second preset temperature, and T2 < T3.

[0048] For the high-temperature steam test operation method of the cooking device provided by the present application, when performing the airtightness test of the cooking device, by controlling the operation of the upper heating tube 2 to heat the heating tube accommodating cavity, so that the high-temperature steam provided by the evaporator is vaporized at a high temperature when entering the heating tube accommodating cavity, avoiding the condensation of the high-temperature steam into liquid water in the heating tube accommodating cavity. Thus, after the test is completed, there is no need to disassemble the top plate shielding assembly 4 to clean the condensed water in the heating tube accommodating cavity, improving the test efficiency.

[0049] Further, in S6, when the dry-burning stage is completed and the evaporator is turned off, the operator can use a compressed air gun and a water-absorbing sponge to clean the inner wall of the cooking cavity 1.

[0050] Further, in S6, when the dry-burning stage is completed and the evaporator is turned off, start a 15s countdown. When the 15s countdown ends, the test program ends and an end prompt is issued to notify the operator to perform the next operation, so as to avoid the problem that the operator is scalded when starting to use a compressed air gun and a water-absorbing sponge to clean the inner wall of the cooking cavity 1 while the temperature in the cooking cavity 1 is still relatively high just after the evaporator ends.

[0051] Optionally, S5 includes the following steps:

[0052] Judge whether T11 < T12. If so, turn on the evaporator. If not, repeat S5, where T11 is the real-time temperature in the evaporator and T12 is the third preset temperature, and T12 > T3.

[0053] Optionally, S6 includes the following steps:

[0054] Judge whether T11 > T12. If so, it means that the dry-burning is completed and the remaining water in the evaporator has been evaporated. At this time, turn off the evaporator. If not, repeat S6.

[0055] Optionally, 65°C < T2 < 75°C, 93°C < T3 < 123°C, 130°C < T12 < 140°C.

[0056] It should be noted that in S3, when T1 > T3, the temperature in the heating tube accommodating cavity is approximately between 93°C and 123°C. At this time, the upper heating tube 2 is turned off. Under the action of the residual heat, the temperature in the heating tube accommodating cavity slowly rises to about 100°C to 137°C, and then gradually decreases to about 100°C to 115°C, so that when the evaporator operates according to the cooking stage program, the temperature in the heating tube accommodating cavity is always at a relatively high temperature, ensuring that the high-temperature steam in the heating tube accommodating cavity can be vaporized until the cooking stage program ends and the evaporator stops delivering high-temperature steam into the cooking cavity 1.

[0057] Optionally, in S1, the preheating stage program includes the following steps:

[0058] S11: The upper heating tube 2 operates for a first preset time t1;

[0059] S12: The upper heating tube 2 cycles on and off with a duty ratio of closing for t2 minutes and opening for t3 minutes per minute to rapidly increase the temperature in the heat pipe accommodating cavity. At the same time, the side heating tube and the evaporator are turned on to prepare to provide high-temperature steam for the cooking cavity 1, and at the same time, the temperature in the cooking cavity 1 is relatively high to maintain the continuous existence of high-temperature steam in the cooking cavity 1.

[0060] Optionally, in S2, the pre-cooking stage program includes the following steps:

[0061] The upper heating tube 2 cycles on and off with a duty ratio of closing for t2 minutes and opening for t3 minutes per minute to further increase the temperature in the heat pipe accommodating cavity so that the high-temperature steam in the heat pipe accommodating cavity can be vaporized.

[0062] Optionally, t2 is 40s and t3 is 20s.

[0063] Optionally, in S3, the cooking stage program includes the following steps:

[0064] The evaporator cycles on and off with a duty ratio of closing for t4 minutes and opening for t5 minutes per minute.

[0065] Optionally, t4 is 15s and t5 is 45s.

[0066] On the other hand, the present invention provides a cooking device. During the airtightness test before leaving the factory, the cooking device operates using the high-temperature steam test operation method of the above cooking device.

[0067] Optionally, the top plate shielding assembly 4 includes a microcrystalline glass 41 and a metal frame 42 provided on the periphery of the microcrystalline glass 41.

[0068] Optionally, a buckle 3 connected to the metal frame 42 is further provided on the top side of the cooking cavity 1, so as to install the top plate shielding assembly 4 on the top side of the cooking cavity 1.

[0069] Optionally, the side heating tube is arranged at the rear side of the cooking cavity 1.

[0070] The above are only some embodiments of the present invention.
