[0002] At present, the existing evaporators generally detect the water level height of the evaporator by means of float water level detection. The control logic of the evaporator with float water level detection is as follows: when water enters, the float is placed at the high water level, which is regarded as the evaporator being full of water, and then heating starts to release steam. When the water in the evaporator is used up and empty, the float drops to the low water level, the evaporator is empty, and the work stops for water replenishment. The high and low water levels of the float will send signals to the controller, and the controller will then send pumping and draining instructions to the pumping and draining system.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Currently, existing evaporators generally use the method of float water level detection to detect the water level height of the evaporator. Evaporators with float water level detection all need to place floats, which results in high costs and poor user experience.

[0029] Based on this, a control method and device for an evaporator provided by an embodiment of the present invention specifically provide a control method applied to an integrated evaporator and a pumping and drainage system of an integrated stove, which can determine the water level height of the evaporator based on the water temperature of the evaporator. The evaporator does not need to place an additional float, which can reduce the cost of the evaporator and improve the user experience.

[0030] For the convenience of understanding this embodiment, a control method for an evaporator disclosed in an embodiment of the present invention will be introduced in detail first.

[0031] Embodiment 1:

[0032] An embodiment of the present invention provides a control method for an evaporator, which is applied to an integrated stove all-in-one machine. The integrated stove all-in-one machine is a multi-functional integrated kitchen appliance that integrates devices such as a gas stove, a range hood, a disinfection cabinet, a steamer, an oven, and a storage cabinet through modular design. Among them, the integrated stove all-in-one machine in this embodiment has a steaming function, and the evaporator of the integrated all-in-one machine is controlled by a power board to release steam to participate in cooking.

[0033] It can be seen from Figure 1Schematic diagram of an integrated range hood Figure 1 The evaporator, water tank and pumping and drainage system of the integrated range hood are shown. Among them, the evaporator is provided with a steam outlet, an NTC (Negative Temperature Coefficient) temperature detection area and a heating unit. The pumping and drainage system includes: a water pump, a drainage pump and a water circuit. The motor control signal can control the water pump and the drainage pump to pump water from the evaporator into the water tank or drain water from the water tank into the evaporator through the water circuit. The NTC temperature detection area is used to detect the water temperature of the evaporator, and the heating unit is used to heat the evaporator.

[0034] Among them, the resistance value of the NTC will decrease significantly as the ambient temperature rises. For example, when the temperature rises by 1°C, the resistance value can decrease by 3%-5%. Therefore, the ambient temperature, that is, the water temperature of the evaporator, can be determined by detecting the change in the resistance value of the NTC in real time.

[0035] Reference can also be made to Figure 2 Schematic diagram of the structure of an evaporator Figure 2 The specific positions and structures of the various components inside the evaporator are shown, including: a steam chamber, an NTC, a heating load and a water inlet.

[0036] Based on the above description, reference can be made to Figure 3 Flowchart of a control method for an evaporator. The control method for the evaporator includes the following steps:

[0037] Step S302, after the evaporator is powered on, determine the mode of the evaporator; among them, the mode of the evaporator includes: a working mode, and the working mode includes: a steaming mode and a humidifying mode.

[0038] The evaporator in this embodiment can be an integrated evaporator. In this embodiment, after the evaporator is powered on, the mode of the evaporator can be determined as a stop mode, a descaling mode and a working mode. Among them, the stop mode means that the user wants the evaporator to stop working, and at this time, the heating operation can be controlled to stop; the descaling mode means that the user wants the evaporator to perform descaling; the working mode means that the user wants the evaporator to emit steam. The working mode of the evaporator in this embodiment can include: a steaming mode and a humidifying mode.

[0039] Step S304, if the mode of the evaporator is the working mode, control the evaporator to perform a preheating operation, and obtain the water temperature of the evaporator after the preheating operation.

[0040] If the mode of the evaporator is the working mode, at this time, the evaporator can be controlled to perform a preheating operation first, and the water temperature of the evaporator can be obtained after the preheating operation. Among them, in this embodiment, the water temperature of the evaporator can be detected by the NTC. As Figure 1As shown, the NTC temperature detection area can detect the water temperature of the evaporator in this area and report the detected water temperature to the power board of the integrated range hood.

[0041] Step S306: Determine the water level height of the evaporator based on the water temperature of the evaporator, and control whether the evaporator performs a water addition operation based on the water level height of the evaporator.

[0042] The power board of the integrated range hood can determine the water level height of the evaporator based on the water temperature of the evaporator, and control whether the evaporator performs a water addition operation based on the water level height of the evaporator.

[0043] In some embodiments, if the water temperature of the evaporator is greater than a preset first threshold, it is determined that the water level height of the evaporator is a low water level; if the water temperature of the evaporator is less than a preset second threshold, it is determined that the water level height of the evaporator is a high water level; wherein, the first threshold is greater than the second threshold.

[0044] In some embodiments, if the water level height of the evaporator is a low water level, control the evaporator to perform a water addition operation; if the water level height of the evaporator is a high water level, control the evaporator not to perform a water addition operation.

[0045] For example, the first threshold can be 130°C, and the second threshold can be 115°C. If the water temperature of the evaporator > 130°C, it means that the evaporator is dry burning at this time. It can be considered that the water level height of the evaporator is a low water level, and it is necessary to control the evaporator to perform a water addition operation. The added water will reduce the temperature inside the evaporator.

[0046] As Figure 1 shown, if the water temperature of the evaporator > 130°C, the water intake and drainage system can be controlled to intake water, reducing the water temperature and protecting the evaporator at the same time. When intaking water, the water temperature of the evaporator needs to be detected. If the water intake and drainage system cannot cool down the evaporator, it is necessary to report water shortage in time to remind the user to add water.

[0047] If the water temperature of the evaporator < 115°C, it means that the amount of water added to the evaporator at this time is sufficient. It can be considered that the water level height of the evaporator is a high water level, and there is no need to control the evaporator to perform a water addition operation.

[0048] In summary, if the water temperature of the evaporator > 130°C, it means that the evaporator is dry burning at this time. It can be considered that the water level height of the evaporator is a low water level; if the water temperature of the evaporator < 115°C, it means that the amount of water added to the evaporator at this time is sufficient. It can be considered that the water level height of the evaporator is a high water level. Therefore, in this embodiment, the water level height of the evaporator can be determined based on the water temperature of the evaporator, and the evaporator does not need to be additionally provided with a float, thereby reducing the cost of the evaporator and improving the user experience.

[0049] An embodiment of the present invention provides a control method for an evaporator. After the evaporator is powered on, the mode of the evaporator is determined. Among them, the modes of the evaporator include: working mode, and the working mode includes: steaming mode and humidifying mode. If the mode of the evaporator is the working mode, control the evaporator to perform a preheating operation, and obtain the water temperature of the evaporator after the preheating operation. Determine the water level height of the evaporator based on the water temperature of the evaporator, and control whether to perform a water addition operation on the evaporator based on the water level height of the evaporator. In this way, the water level height of the evaporator can be determined based on the water temperature of the evaporator, and the evaporator does not need to be additionally provided with a float, thereby reducing the cost of the evaporator and improving the user experience.

[0050] Embodiment 2:

[0051] This embodiment provides another control method for an evaporator. This method is implemented on the basis of the above embodiment. Refer to Figure 4 the flowchart of another control method for an evaporator shown in

[0052] Step S402, after the evaporator is powered on, control the evaporator to perform a drainage operation; obtain the mode of the evaporator input by the user through the keypad of the evaporator.

[0053] It can be referred to Figure 5 the schematic diagram of a control logic of an evaporator shown in Figure 5 As shown in

[0054] When the evaporator is powered on, it will enter the stop state. If the evaporator is powered on for the first time, first perform a drainage operation for 30 seconds to empty the accumulated water inside the evaporator. Then continuously wait for the mode sent by the keypad. Among them, the modes of the evaporator in this embodiment include: working mode, and the working mode includes: steaming mode and humidifying mode.

[0055] In some embodiments, the modes of the evaporator further include: stop mode and descaling mode; if the mode of the evaporator is the stop mode, control the evaporator to perform a drainage operation; re-obtain the mode of the evaporator input by the user through the keypad of the evaporator; if the mode of the evaporator is the descaling mode, control the evaporator to perform a descaling operation. Figure 5 As shown in

[0056] In some embodiments, the evaporator can be controlled to perform a water pumping operation and a heating operation in sequence, and determine whether the evaporator fails during the heating operation; if the evaporator does not fail, control the evaporator to perform multiple descaling operations; wherein, each descaling operation includes: a water inlet operation, a heating operation, and a drainage operation performed in sequence.

[0057] As Figure 5 shown, if the mode of the evaporator is the descaling mode, the water pumping operation can be triggered for 5 seconds first, aiming to make the water level height of the evaporator reach the lowest water level line, and then the forced heating operation is performed for 30 seconds, and it is judged whether a failure occurs during the heating operation.

[0058] In some embodiments, the water temperature of the evaporator can be obtained during the heating operation; if the water temperature of the evaporator continuously rises during the heating operation, it is determined that the evaporator does not fail; if the water temperature of the evaporator does not continuously rise during the heating operation, it is determined that the evaporator fails.

[0059] As Figure 5 shown, in this embodiment, the failure judgment can be performed before the evaporator completes preheating: obtain the water temperature of the evaporator through the NTC, and at this time the water temperature has not reached the boiling point and the water temperature should continuously rise. If the water temperature continuously rises, it is determined that the evaporator does not fail; if the water temperature does not continuously rise, it means that the evaporator fails, for example: heating failure or NTC failure.

[0060] As Figure 5 shown, each descaling operation in this embodiment includes: a water inlet operation, a heating operation, and a drainage operation performed in sequence. Assuming that 3 descaling operations need to be performed, this embodiment can set a counter for 3 stages, and the count value is incremented by 1 every time a cycle is completed. After reaching the full count, it jumps to the next stage until it stops working after completion and waits for the keypad to shut down. The process of the cycle can be: a water inlet operation for 20 seconds, a heating operation for 15 seconds, and a drainage operation for 25 seconds.

[0061] In some embodiments, the water temperature of the evaporator can be obtained during the heating operation of each descaling operation; the water level height of the evaporator is determined based on the water temperature of the evaporator; if the water level height of the evaporator is at the low water level, it is determined that the mode of the evaporator is the stop mode.

[0062] As Figure 5 shown, in this embodiment, the failure judgment can be performed during the heating operation of each descaling operation. For example: obtain the water temperature of the evaporator. If the water temperature of the evaporator > 130 °C, it means that the evaporator is dry burning at this time. It can be considered that the water level height of the evaporator is at the low water level and the evaporator is short of water. At this time, it is determined that the mode of the evaporator is the stop mode. At this time, the cycle of the descaling operation needs to be reset, and the descaling status count will not be cleared.

[0063] Step S404, if the mode of the evaporator is the working mode, control the evaporator to perform a preheating operation, and obtain the water temperature of the evaporator after the preheating operation.

[0064] In some embodiments, if the mode of the evaporator is the working mode, control the evaporator to perform a water pumping operation and a preheating operation in sequence, and determine whether the evaporator fails during the preheating operation.

[0065] As Figure 5 shown, if the evaporator enters the working mode for the first time, a 5-second water pumping operation will be triggered to make the water level height of the evaporator reach the lowest water level line. Then, a forced heating operation is performed for 30 seconds, and a fault judgment is carried out simultaneously. The principle is the same as the fault judgment of the descaling operation and will not be elaborated here.

[0066] Before entering the cycle of the working mode, the evaporator can be heated to the boiling point of water, with the aim of preheating the evaporator so that steam can be released in time during operation. In modes such as fermentation, the steam time is short, working 7 seconds per minute and ending before the steam can be released in time, so the evaporator needs to perform a preheating operation.

[0067] Step S406, determine the water level height of the evaporator based on the water temperature of the evaporator, and control whether the evaporator performs a water adding operation based on the water level height of the evaporator.

[0068] As Figure 5 shown, the cycle of the working mode of the evaporator can be divided into 3 stages: a heating operation, a water adding operation, and a temperature detection operation. Heating operation stage: The working mode of the evaporator is controlled by a cooking performance temperature control function. If the water temperature > 130°C, it enters the water adding operation stage. Water adding operation stage: A water pumping operation is performed for 10 seconds, and then it enters the temperature detection operation stage. Temperature detection operation stage: After experiencing the water adding operation stage, if the water temperature of the evaporator drops below 115°C, it indicates that water has been added from the water tank to the integrated evaporator, and the evaporator is not short of water at this time; otherwise, the evaporator is short of water. If the evaporator is not short of water, it re-enters the heating operation stage.

[0069] The above method provided by the embodiments of the present invention can determine the water level height of the evaporator based on the water temperature of the evaporator. The evaporator does not need to be additionally provided with a float, thereby reducing the cost of the evaporator and improving the user experience. The evaporator can cooperate with a pumping and drainage system to generate steam; the evaporator can also automatically detect problems such as water shortage, heating failure, and NTC failure, thereby realizing automatic fault detection of the evaporator.
