Abstract
Description
Technical Field
[0001] This invention relates to the field of kitchen appliance technology, and in particular to a control method for descaling integrated stoves and evaporators. Background Technology
[0002] An integrated cooktop mainly consists of the cooktop body and a lower-level unit, which can include single-cavity steam and grill or dual-cavity steam and grill structures. Specifically, the lower-level unit can have various configurations such as steam + grill, steam and grill combined with steam, and steam and grill combined with microwave steam and grill. To achieve the steaming function, the integrated cooktop needs to be equipped with a steam generator to supply steam to the lower-level unit.
[0003] Existing steam generators typically consist of a steam body and steam delivery pipes. Water is converted into steam in the steam body, and the steam enters the cooking chamber of the lower-level unit through the steam delivery pipes to achieve the steaming function. After a period of use, scale easily forms inside the steam body. To ensure food safety, improve cooking quality, and increase steam processing efficiency, timely descaling is necessary.
[0004] Because of the presence of the steam delivery pipeline, the lower-level machine cannot cook during the descaling process of the existing steam generator. Otherwise, the descaling steam in the steam generator would enter the cooking chamber of the lower-level machine, causing food contamination. In order to avoid food contamination, the lower-level machine cannot cook during the descaling process, resulting in a poor user experience. Summary of the Invention
[0005] The purpose of this invention is to propose a control method for descaling integrated stoves and evaporators, which solves the problem that the lower-level machine cannot cook during existing evaporator descaling, resulting in a better user experience.
[0006] To achieve this objective, the present invention employs the following technical solution:
[0007] An integrated cooktop includes: a box-type cooking device, comprising a box body with a cooking cavity for cooking food formed inside the box; a water tank with a space for adding descaling agent inside; a water inlet pipe with a water pump installed thereon, one end of the water inlet pipe being connected to the water tank, the water pump being used to pump the descaling agent aqueous solution in the water tank into the water inlet pipe; an evaporator assembly connected to the other end of the water inlet pipe, the descaling agent aqueous solution being able to enter the evaporator assembly through the water inlet pipe and be heated to a set temperature to remove scale from the evaporator assembly; and a steam valve assembly disposed between the evaporator assembly and the box-type cooking device, the steam valve assembly being able to prevent steam from the evaporator assembly from entering the box-type cooking device, the box-type cooking device being able to cook food during the descaling process of the evaporator assembly.
[0008] In one preferred embodiment, the integrated stove further includes a pressure relief valve and a pressure relief exhaust pipe connected together. The pressure relief exhaust pipe is connected to the evaporator assembly through the pressure relief valve. When the amount of steam generated during the descaling process of the evaporator assembly is greater than a set value, the excess steam can be discharged through the pressure relief valve and the pressure relief exhaust pipe.
[0009] In one preferred embodiment, the integrated stove further includes a temperature detection device for measuring the heating temperature of the descaling agent aqueous solution in the evaporator assembly.
[0010] On the other hand, the present invention adopts the following technical solution:
[0011] The evaporator descaling control method, based on the aforementioned integrated stove, involves a steam valve assembly cutting off the channel between the evaporator assembly and the box-type cooking device during the descaling process of the evaporator assembly. The descaling operation of the evaporator assembly does not affect the cooking of food by the box-type cooking device.
[0012] In one preferred embodiment, the evaporator descaling control method includes the following steps: adding descaling agent to the water tank and starting the descaling program; starting the water inlet pump to pump the descaling agent aqueous solution into the evaporator assembly through the water inlet pipe; starting the heating element of the evaporator assembly to heat the descaling agent aqueous solution to a set temperature; closing the steam valve assembly to cut off the passage between the evaporator assembly and the box-type cooking device to prevent steam in the evaporator assembly from entering the box-type cooking device; and starting the box-type cooking device to cook food.
[0013] In one preferred embodiment, during the descaling process of the evaporator assembly, when the amount of steam generated by the evaporator assembly exceeds a set value, the excess steam is discharged outside the integrated stove through a pressure relief valve and a pressure relief exhaust pipe.
[0014] In one preferred embodiment, the parameter for determining whether to descale the evaporator assembly is whether the steaming function usage time of the box-type cooking device has reached a set value.
[0015] In one preferred embodiment, during the heating of the descaling agent aqueous solution by the heating tube of the evaporator assembly, a temperature detection device continuously detects whether the temperature of the descaling agent aqueous solution exceeds a set upper limit value.
[0016] In one preferred embodiment, the evaporator assembly includes two sets of heating tubes, one set of which has a lower power than the other set. During the descaling process of the evaporator assembly, the high-power heating tube is not in operation, while the low-power heating tube is used to heat the descaling agent aqueous solution. The sum of the power required for cooking by the box-type cooking device and the power of the low-power heating tube is less than the rated total power of the lower-level machine.
[0017] In one preferred embodiment, the box-type cooking device includes a first cavity with a baking function and a second cavity with a microwave function. After starting the descaling program, if the baking function of the first cavity is started first, the microwave function of the second cavity will be at a medium or low setting; if the microwave function of the second cavity is started first and is at a medium or low setting, the first cavity can start the baking function; if the microwave function of the second cavity is started first and is at a high setting, when the baking function of the first cavity is started, the microwave power of the second cavity switches from high to medium heating.
[0018] The integrated stove disclosed in this invention includes a box-type cooking device, a water box, a water inlet pipe, a water inlet pump, an evaporator assembly, and a steam valve assembly. The steam valve assembly can prevent steam in the evaporator assembly from entering the box-type cooking device. The water box, the water inlet pipe, and the evaporator assembly form a closed fluid channel. During the descaling process of the evaporator assembly, the box-type cooking device can cook food by baking and microwaving, solving the problem that cooking cannot be carried out during the descaling process of the evaporator in existing integrated stoves. This provides a better user experience and is more practical.
[0019] The evaporator descaling control method disclosed in this invention involves a steam valve assembly cutting off the channel between the evaporator assembly and the box-type cooking device during the descaling process of the evaporator assembly, preventing steam in the evaporator assembly from entering the cooking device. The descaling operation of the evaporator assembly does not affect the normal cooking of food by the box-type cooking device, resulting in a good user experience and high cooking efficiency.

[0040] This embodiment discloses an integrated stove, such as... Figures 1 to 5 As shown, the integrated stove includes a box-type cooking device 1, a water box 2 with an internal space for adding descaling agent, a water inlet pipe 3, a water inlet pump 4, an evaporator assembly 5, and a steam valve assembly 6. The water inlet pump 4 is installed on the water inlet pipe 3, and the steam valve assembly 6 is installed between the evaporator assembly 5 and the box-type cooking device 1.
[0041] The box-type cooking device 1 includes a box body, within which a cooking cavity for cooking food is formed. In this embodiment, the box-type cooking device 1 includes a first cavity with a baking function and a second cavity with a microwave function; that is, the integrated stove is equipped with a dual-cavity microwave-steam-bake device. A heating fan assembly 11 is provided on the first cavity to create a high-temperature baking environment within the first cavity; a microwave assembly 12 is provided on the second cavity to generate microwaves within the second cavity. In this embodiment, the first cavity is the left cavity, and the second cavity is the right cavity; "left" and "right" refer to the left and right sides when the user faces the box-type cooking device 1, respectively.
[0042] One end of the water inlet pipe 3 is connected to the water box 2, and the other end of the water inlet pipe 3 is connected to the evaporator assembly 5. The water inlet pump 4 is used to pump the descaling agent aqueous solution in the water box 2 into the water inlet pipe 3, and then into the evaporator assembly 5 through the water inlet pipe 3.
[0043] The descaling agent aqueous solution is heated to a set temperature in the evaporator assembly 5 to remove scale from the evaporator assembly 5. To accurately control the temperature, in this embodiment, the integrated stove also includes a temperature detection device for measuring the heating temperature of the descaling agent aqueous solution in the evaporator assembly 5.
[0044] The steam valve assembly 6 prevents steam from the evaporator assembly 5 from entering the box-type cooking device 1. The water box 2, water inlet pipe 3, and evaporator assembly 5 form a closed fluid channel. During the descaling process of the evaporator assembly 5, the box-type cooking device 1 can cook food by baking and microwaving. That is, during the descaling process of the evaporator assembly 5, the box-type cooking device 1 is only unable to cook by steaming, without any other impact. This solves the problem of not being able to cook during the descaling process of the evaporator in existing integrated stoves, resulting in a better user experience and greater practicality.
[0045] The control method for descaling the evaporator of the integrated stove is as follows: during the descaling process of the evaporator assembly 5, the steam valve assembly 6 cuts off the channel between the evaporator assembly 5 and the box-type cooking device 1, so that the descaling operation of the evaporator assembly 5 does not affect the cooking of food by the box-type cooking device 1.
[0046] The specific structure for achieving "one end of the water inlet pipe 3 connected to the water box 2" is not limited. In this embodiment, the integrated stove also includes a return water pump 9. The water box 2, the water inlet pump 4, and the return water pump 9 are arranged adjacent to each other on one side of the top of the box-type cooking device 1. The water box 2, the water inlet pump 4, and the return water pump 9 share a water inlet and return tee 31. The water box 2 is connected to the water inlet pipe 3 through the water inlet and return tee 31, and the water inlet pipe 3 is connected to the evaporator assembly 5.
[0047] Based on the above structure, the integrated stove also includes a control device, which is connected to the water inlet pump 4, the evaporator assembly 5, and the steam valve assembly 6. In this embodiment, the control device can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program to control the water inlet pump 4, the evaporator assembly 5, and the steam valve assembly 6 to achieve their functions.
[0048] like Figures 4 to 9 As shown, the integrated stove also includes a pressure relief valve 7 and a pressure relief exhaust pipe 8 connected together. The pressure relief exhaust pipe 8 is connected to the evaporator assembly 5 through the pressure relief valve 7. When the amount of steam generated during the descaling process of the evaporator assembly 5 is greater than the set value, the excess steam can be discharged through the pressure relief valve 7 and the pressure relief exhaust pipe 8.
[0049] To simplify the connection structure, the integrated stove also includes an evaporator four-way pipe 53, with four passages connecting the evaporator assembly 5, the first chamber steam valve 61, the second chamber steam valve 62, and the pressure relief valve 7, respectively. The front end of the pressure relief valve 7 is connected to the pressure relief exhaust pipe 8. The steam flow path is simpler and smoother, with less flow resistance and lower energy consumption; all pipelines are rationally designed and occupy less space.
[0050] The first chamber steam valve 61 is installed on the first chamber steam inlet pipe 51. When the first chamber steam valve 61 is open, the steam in the evaporator assembly 5 can enter the first chamber through the first chamber steam inlet pipe 51, and cooking can be carried out by steaming. When the first chamber steam valve 61 is closed, the steam in the evaporator assembly 5 cannot enter the first chamber steam inlet pipe 51.
[0051] Correspondingly, the second chamber steam valve 62 is installed on the second chamber steam inlet pipe 52. When the second chamber steam valve 62 is open, the steam in the evaporator assembly 5 can enter the second chamber through the second chamber steam inlet pipe 52, and cooking can be carried out by steaming. When the second chamber steam valve 62 is closed, the steam in the evaporator assembly 5 cannot enter the second chamber steam inlet pipe 52.
[0052] When the evaporator assembly 5 generates a large amount of steam, and the first chamber steam valve 61 and the second chamber steam valve 62 malfunction simultaneously, the steam in the evaporator assembly 5 is discharged into the pressure relief exhaust pipe 8 through the pressure relief valve 7.
[0053] The specific locations of the aforementioned devices and pipelines are not limited. In this embodiment, the installation height of the first chamber steam valve 61 is parallel to the evaporator four-way pipe 53, and the second chamber steam valve 62 is connected to the evaporator four-way pipe 53 via an elbow. This staggered height arrangement makes full use of space and effectively reduces the volume of the integrated stove. The installation height of the second chamber steam valve 62 can be lower than that of the water inlet pipe 3, ensuring that the water inlet pipe 3 and the second chamber steam inlet pipe 52 will not collide, facilitating disassembly and assembly, and minimizing the overall space required.
[0054] It is understood that the integrated stove also includes existing devices such as the cooktop assembly 100 and the air handling unit assembly 200 to perform the basic functions of an existing integrated stove. After determining the positions of the cooktop assembly 100 and the air handling unit assembly 200, the heating fan assembly 11, the evaporator assembly 5, the magnetron assembly, and the water box 2 are all positioned above the box-type cooking device 1, together forming the lower-level unit. The first chamber exhaust pipe assembly and the second chamber exhaust pipe assembly are respectively connected to the exhaust box to promptly discharge the steam in the first and second chambers.
[0055] The integrated stove has the same device and structure as existing integrated stoves, so it will not be described in detail here.
[0056] like Figure 10 As shown, the control method for evaporator descaling includes the following steps:
[0057] Whether to descale the evaporator assembly 5 depends on whether the steaming function of the box-type cooking device 1 has reached the set value. The specific value of the steaming function usage time is not limited and can be determined according to the actual usage situation.
[0058] Add descaling agent to water tank 2 and start the descaling program.
[0059] The inlet pump 4 starts and pumps the descaling agent solution into the evaporator assembly 5 through the inlet pipe 3 according to the program.
[0060] The heating element of evaporator assembly 5 is activated to heat the descaling agent aqueous solution to the set temperature. The specific power of the heating element is not limited, as long as it meets the usage requirements. In this embodiment, the heating element is 600W, providing high heating efficiency.
[0061] The temperature of the descaling agent aqueous solution is continuously monitored by a temperature detection device to ensure it does not exceed a set upper limit. In this embodiment, the temperature detection device is preferably an NTC (negative temperature coefficient) sensor located at the bottom. The specific value of the set temperature is not limited and can be determined according to actual usage. In this embodiment, when the NTC sensor detects that the temperature inside the evaporator assembly 5 reaches 50°C, the heating element stops heating, and the evaporator assembly 5 enters the soaking stage. When the temperature inside the evaporator assembly 5 is <40°C, the heating element starts heating, and the above process lasts for 30 minutes.
[0062] The return water pump 9 pumps water from the evaporator assembly 5 back to the water box 2, and the number of cycles of the above program is incremented by one. After the number of program cycles accumulates to the set value, the descaling program ends.
[0063] When the heating element of the evaporator assembly 5 heats the descaling agent aqueous solution, the steam valve assemblies 6 corresponding to the left and right chambers are both closed, cutting off the passage between the evaporator assembly 5 and the box-type cooking device 1, thereby preventing steam in the evaporator assembly 5 from entering the box-type cooking device 1. The box-type cooking device 1 is then activated to cook food.
[0064] When the amount of steam generated by the evaporator assembly 5 exceeds the set value, the pressure relief valve 7 is activated to release steam, and the excess steam is discharged outside the integrated stove through the pressure relief valve 7 and the pressure relief exhaust pipe 8.
[0065] In order to ensure that the box cooking device 1 can still cook food during the descaling process of the evaporator assembly 5, in addition to using the steam valve assembly 6 to prevent steam from the evaporator assembly 5 from entering the box cooking device 1, a power distribution scheme is also required to avoid the box cooking device 1 being unable to cook during the descaling process of the evaporator assembly 5 due to insufficient power.
[0066] In this embodiment, the evaporator assembly 5 includes two sets of heating tubes, one set of which has a lower power than the other. During the descaling process of the evaporator assembly 5, the high-power heating tube is not in operation, while the low-power heating tube is used to heat the descaling agent aqueous solution. The specific power values of the two sets of heating tubes are not limited, as long as they meet the needs of heating the descaling agent aqueous solution and normal production steam.
[0067] The purpose of using only a low-power heating element to heat the descaling agent solution is to ensure that the sum of the power required for cooking by the box-type cooking device 1 and the power of the low-power heating element is less than the rated total power of the lower-level machine.
[0068] This embodiment uses a lower-level unit with a rated total power of 3050W as an example. The evaporator assembly 5 has two heating elements, one 600W and the other 1200W. During normal cooking, the 1200W heating element is sufficient. When a large amount of steam is required, both the 600W and 1200W heating elements operate simultaneously. When descaling is needed, the 1200W heating element is turned off, and only the 600W heating element is used to heat the descaling agent solution.
[0069] The left cavity of the box-type cooking appliance 1 is equipped with two heating elements, 900W and 600W respectively. Depending on the heating capacity of the baking function, it is possible to select to activate only the 900W heating element or to activate both heating elements simultaneously. The microwave function of the right cavity of the box-type cooking appliance 1 has three levels: high, medium, and low, corresponding to microwave input powers of 1560W, 900W, and 400W respectively.
[0070] Given that the heating element used to heat the descaling agent solution will consume a certain amount of power after the descaling process is started, the power that can be allocated to each of the two chambers of the box-type cooking appliance 1 will be limited. For example... Figure 11As shown, the left chamber's baking function and the right chamber's microwave function are activated, and the steam valve assemblies 6 of the corresponding left and right chambers are checked to see if they are both closed. At this time, the left chamber's baking function uses both 900W and 600W heating elements simultaneously for heating, while the right chamber's microwave function is set to medium or low speed until cooking is complete. During this time, descaling of the evaporator assembly 5 requires 600W, the baking function requires a total of 1500W, and the microwave function, taking medium speed as an example, requires 900W, totaling 3000W, which does not exceed the rated total power (3050W). Therefore, both chambers can be opened for cooking during the descaling process of the evaporator assembly 5.
[0071] Correspondingly, if the microwave function of the right cavity is activated first and is set to medium or low, the baking function of the left cavity can be activated. That is, in this working mode, the order in which the left and right cavities are activated does not affect the working mode.
[0072] like Figure 12 As shown, the microwave function of the right cavity and the baking function of the left cavity are activated, and the steam valve assembly 6 of the corresponding left and right cavities is checked to see if they are both closed. If the microwave function of the right cavity is activated first and is at the high setting (1560W), the baking function of the first cavity will require at least 900W to activate. In addition, the descaling of the evaporator assembly 5 will require 600W, totaling 3060W, which exceeds the rated total power (3050W). Therefore, the inverter appliance operates, and the microwave power of the right cavity switches from the high setting to the medium setting (900W) for heating.
[0073] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
