The specific meaning of the above terms in the present invention can be understood in a specific case by a worker of ordinary skill in the art.
In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Example 1
Cooking devices such as steam ovens, steam boxes and the like which are sold in the market at present are internally provided with steam generating systems. The steaming oven can be divided into an embedded steaming oven, a desk type steaming oven and the like. At present, most embedded steaming ovens adopt a water boiling type steam generator, such as: the stainless steel plate water boiling type, stainless steel box water boiling type, heating film box water boiling type steam generator and water boiling type steam generator have the functions of descaling and waste water discharge, so that the water boiling type steam generator can be applied to an embedded steaming and baking box to facilitate cleaning work such as descaling and waste water discharge for users. However, the water boiling type steam generator also has certain disadvantages, such as large occupied space, relatively high cost, large energy consumption and low heat efficiency. The instant heating type steam generator has the advantages of small volume, low cost, low energy consumption, large amount of generated steam and the like.
However, in the prior art, when the temperature of the steam generator is too high, in order to prevent the steam generator from being damaged due to the too high temperature and to bring potential safety hazards to cooking equipment and kitchens, the steam generator is generally directly controlled to stop operating when the temperature of the steam generator is higher than a temperature critical point, so that the steam generator is automatically cooled until the temperature is in a normal temperature range.
Therefore, during the cooling period, the stopping of the steam generator can seriously affect the cooking process of the cooking device, affect the mouthfeel of food and bring poorer use experience to users.
In view of the above, the present application provides a control method and a control device for an instant heating type steam generating system, so as to solve the problem that the stopping of the steam generator during the cooling period can seriously affect the cooking process of the cooking device.
Meanwhile, due to the self structural reasons of the instant heating type steam generator, the instant heating type steam generator only has a water inlet and a steam outlet, and has no waste water outlet, scale can be generated after long-time use, and a scale removal process is also needed. Therefore, the instant heating type steam generator is only applied to the table type steam oven at present so as to be convenient for a user to scale and clean, and if the instant heating type steam generator is directly applied to the embedded type steam oven, the user cannot scale and clean the instant heating type steam generator because the embedded type steam oven is inconvenient to move.
The present application therefore also provides an instant heating steam generation system for descaling and cleaning the instant heating steam generation system.
Embodiments of the present application are described below with reference to fig. 1 to 3.
According to a first aspect of the present invention, there is provided a control method of an instant heating type steam generation system, the control method comprising the steps of:
s1, when the instant heating type steam generator 8 is controlled to heat, the current temperature of the instant heating type steam generator 8 is obtained;
when a user uses the steam mode of the instant heating type steam generation system, the water pump 10 conveys purified water in the purified water tank 1 to the instant heating type steam generator 8, and after the instant heating type steam generator 8 works, the other end of the instant heating type steam generator 8 discharges steam. In this embodiment, the starting mode of the steam mode is not limited, for example, the steam mode may be started by a steam button of a touch control screen on the instant heating type steam generating system, or may be started by a steam button separately provided on the instant heating type steam generating system, which may be changed by a person skilled in the art according to actual situations.
When the instant steam generator 8 is heated, the current temperature of the instant steam generator 8 needs to be obtained through the bulb 9. The higher the current temperature of the instant heating type steam generator 8, the higher the efficiency of converting the purified water into steam.
S2, when the current temperature is higher than a preset temperature threshold, controlling a water inlet module to be started, and starting water inlet of the instant heating type steam generator 8;
In the working process, if the current temperature is higher than the preset temperature threshold value, it is indicated that the internal water shortage of the instant heating type steam generator 8 leads to dry heating, so that the instant heating type steam generator 8 needs to be cooled. The conventional cooling mode is to directly stop the operation of the instant heating type steam generator 8 to cool the instant heating type steam generator by itself, but in the embodiment, the water inlet module can be controlled to be opened to allow purified water to flow into the instant heating type steam generator 8, so that the instant heating type steam generator 8 can be cooled by a certain amount of purified water.
S3, when the current temperature is within the preset temperature threshold, controlling the water inlet module to be closed, and stopping water inlet of the instant heating type steam generator 8; the preset temperature threshold is the temperature required by the instant heating steam generator 8 to generate steam.
As the inflow of purified water into the instant heating type steam generator 8 increases, the current temperature of the instant heating type steam generator 8 gradually decreases such that the current temperature falls again within the preset temperature threshold. Since the preset temperature threshold is the temperature required by the instant heating type steam generator 8 to generate steam, the current temperature of the instant heating type steam generator 8 is controlled within the preset temperature threshold. Therefore, water inflow is stopped, and steam can be continuously generated while the temperature is reduced.
So configured, the current temperature of the instant heating type steam generator 8 can be reduced by feeding water into the instant heating type steam generator 8 when the current temperature is higher than a preset temperature threshold. In addition, the instant heating type steam generator 8 can generate steam at the preset temperature threshold, so that the current temperature is controlled at the preset temperature threshold, the steam can be continuously generated while the temperature is reduced, the normal operation of the cooking process is ensured, the taste of food is not influenced, and the use experience of a user is improved.
In an alternative embodiment, in steps S2 and S3, PID adjustment may be performed on the water intake module. In particular, the water inlet time, switching frequency or other parameters of the water inlet module can be adjusted.
For example, in this embodiment, the PID adjustment of the water inlet module specifically includes the following steps:
s4, PID adjustment is carried out on the water inlet module according to the relation between the water inlet speed of the water inlet module and the current temperature so that the water inlet module is opened and closed.
T is the set temperature, si is the pump initial rate, tb is the boiler temperature, tu: the threshold value of the water pump is triggered,
td, stop Water Pump threshold, tp, boiler protection threshold (220-230 ℃ C.)
The PID formula is as follows:
the boiler temperature Tb is in the range from triggering the water pump threshold Tu to (the set temperature T+45), and the water inlet speed= (Tb-Tu)/2+Si;
the working principle is as follows: when the instant heating type steam generator 8 is operating normally, the water pump intake speed=tb boiler temperature-Tu trigger water pump threshold (e.g. 60 ℃) divided by 2+ pump initial rate when the boiler temperature Tb is in the range of trigger water pump threshold Tu (e.g. 60 ℃) to T set temperature (e.g. 60+45 ℃). When the temperature sensed by the temperature sensing bag 9 is reduced to 80 ℃, the water pump stops pumping water.
The mathematical relationship between the water inflow and the current temperature can be summarized through multiple experimental data, so that the mathematical relationship can be simulated through a PID algorithm, the current temperature of the instant heating type steam generator 8 can be maintained at a higher level, and high-temperature steam can be efficiently circulated and continuously output. Of course, a mathematical model can be directly established through a PID algorithm, and the water inflow amount can be adjusted, so that the current temperature of the instant heating type steam generator 8 can be maintained at a higher level.
By means of the arrangement, through PID adjustment on the water inlet module, the water inlet speed of the water inlet module and the temperature required by the instant heating type steam generator 8 for generating steam can be enabled to be within a reasonable range, and the situation that the current temperature of the instant heating type steam generator 8 is low due to excessive water addition, so that the steam generated by the instant heating type steam generator 8 is reduced or no steam is generated is avoided. Therefore, the instant heating type steam generator 8 can efficiently and continuously output high-temperature steam, and the working efficiency of the instant heating type steam generator 8 is improved.
In an alternative embodiment, the preset temperature threshold is between 80 ℃ and 200 ℃. Of course, the present embodiment is merely illustrative of a specific section of the preset temperature threshold, but is not limited thereto, and those skilled in the art may change the section according to actual situations, and may achieve the same technical effects.
In an alternative embodiment, the control method further comprises:
and S5, when the current temperature is higher than the preset temperature threshold and reaches the warning temperature, controlling the instant heating type steam generator 8 to stop working.
So set up, when the current temperature of instant heating type steam generator 8 is higher than preset temperature threshold value and reaches warning temperature, indicate that the water supplementing instant heating type steam generator 8 can not be cooled down, indicate that the working procedure or the working element of instant heating type steam generator 8 is abnormal. At this time, the heating element of the instant heating type steam generator 8 is required to stop working, so as to perform power-off protection on the instant heating type steam generator 8, and prevent the instant heating type steam generator 8 from high temperature, thereby causing hidden danger to the electrical element of the cooking appliance and the personal and property safety of a user.
In an alternative embodiment, the alert temperature is between 220 ℃ and 230 ℃.
Further, when the user feels that the instant heating type steam generating system needs to be descaled, the descaled mode of the instant heating type steam generating system needs to be started, and of course, the starting mode is not limited in this embodiment, for example, the instant heating type steam generating system may be started by a descaled button of a touch control screen, or the instant heating type steam generating system may be started by a descaled button separately provided on the instant heating type steam generating system, and those skilled in the art may change according to practical situations.
In the descaling mode, the control method comprises the following steps:
s6, acquiring a working mode of the instant heating type steam generation system, wherein the working mode comprises a descaling mode;
s7, starting a descaling mode, conveying descaling water into the instant heating type steam generator 8, and controlling the instant heating type steam generator 8 to heat at a preset duty ratio; in this embodiment, the instant steam generator 8 may be alternately heated at a 15:15 duty cycle. Of course, the present embodiment is merely illustrative of specific values of the duty ratio, but is not limited thereto, and those skilled in the art may vary according to actual situations, and may achieve the same technical effects.
S8, stopping heating for a second preset time period after heating for the first preset time period; the first preset duration may be 4 cycles of 2 minutes each. The second preset time period may be 5 minutes, and in the second preset time period, the scale remover is waited to react with the scale, so that the scale in the instant heating type steam generator 8 is softened, dissolved and shed slowly. Of course, the embodiment is merely to illustrate specific values of the first preset duration and the second preset duration, but is not limited thereto, and those skilled in the art may change according to actual situations, so as to achieve the same technical effects.
S9, controlling the instant heating type steam generator 8 to discharge sewage with scale.
After the sewage is discharged, the next round of water pumping by the water inlet pump 10 is carried out for 5 seconds, the instant heating type steam generator 8 heats and softens the scale until the descaling water in the clean water tank is completely pumped, and the total time is about 30 minutes.
Of course, the present embodiment is merely illustrative of the number of cycles and the total time, but is not limited thereto, and those skilled in the art may change the number of cycles according to actual circumstances, and may achieve the same technical effects.
Further, in the descaling mode, the control method thereof includes the steps of:
after step S9, further comprising:
s10, acquiring the actual water level of the descaling water in the water purifying tank 1;
it is necessary to obtain the actual level of the descaling water in the fresh water tank 1 in real time to determine the amount of the remaining amount of the descaling water in the fresh water tank 1.
S11, when the descaling water in the water purifying tank 1 is not contained, automatically supplementing purified water into the water purifying tank 1;
when the clean water tank 1 does not have the descaling water, it means that the descaling water in the clean water tank 1 has been completely pumped, and the instant steam generator 8 needs to be cleaned. Therefore, it is necessary to automatically supply purified water to the purified water tank 1. Of course, it can be manually supplemented. The user needs to take out the fresh water tank 1, add purified water to the highest level of the fresh water tank 1, and then put the fresh water tank 1 back in place.
S12, controlling the water inlet module to be opened, and supplementing the purified water into the instant heating type steam generator 8;
and then, controlling the water inlet module to be opened, and inputting purified water into the instant heating type steam generator 8 for cleaning and heating.
And S13, controlling the instant heating type steam generator 8 to heat purified water and discharging the purified water.
When the water in the instant heating type steam generator 8 reaches 80 ℃, the instant heating type steam generator 8 and the water inlet pump 10 stop working for 10 seconds, and the water is discharged outwards after 10 seconds.
The above is 1 cycle, and a plurality of cycles, for example, 3 cycles, may be performed, and the total time of 3 cycles is about 10 minutes. After 3 cycles, the control panel of the instant heating type steam generation system prompts the descaling to be completed.
Before the descaling mode is started, the method further comprises the following steps:
s14, acquiring accumulated working time of the instant heating type steam generator 8;
s15, when the accumulated working time length reaches a preset accumulated time length, a prompt signal is sent out;
s16, after the instant heating type steam generator 8 is controlled to heat purified water and the purified water is discharged, the accumulated working time is cleared.
For example, after the whole steaming related function is accumulated for 50 hours, the control panel sends a prompt signal, the prompt signal can be that a cleaning icon on the control panel flashes, and a continuous beeping sound is generated along with 5 sounds, so that a user is prompted to remove the scale, after the user operates a complete scale removing program once, the scale removing reminding timing is cleared, otherwise, when the steam related program is entered each time, the cleaning icon can flash and buzzing again, and the user is prompted to remove the scale, so that the safety of the steaming and baking box is ensured.

Example 3
In a third aspect, the present invention further provides an instant heating type steam generation system, and the structure of the instant heating type steam generation system is described below.
The instant heating type steam generation system mainly comprises a clean water tank 1, a water pump 10 and an instant heating type steam generator 8. Specifically, in the embodiment of the present invention, the clean water tank 1 is provided with an opening for adding clean water and descaling water and a water outlet for discharging clean water and descaling water to the outside. For the arrangement of the clean water and the descaling water, for example, the interior of the clean water tank 1 can be directly divided into two cavities, one cavity is used for storing the clean water, and the other cavity is used for storing the descaling water. The clean water tank 1 can be provided with only one cavity, the cavity is used for storing clean water, when a user wants to use the descaling water, the descaling agent is directly put into the clean water in proportion in person, and the descaling agent can be completely dissolved in the clean water within a certain time, so that the descaling water can be formed. Of course, a descaling box specially used for storing the descaling agent can be arranged in the clean water tank 1, and when a user wants to start the descaling mode, the descaling box can be automatically opened only by pressing a descaling button, so that the descaling agent in the descaling box is put into the clean water tank 1, and the quantity of the descaling agent in the descaling box is configured according to the proportion of clean water in the clean water tank 1.
The present embodiment is merely an example of the way to set up the purified water and the descaling water in the fresh water tank 1, but is not limited thereto, and those skilled in the art may vary according to the actual circumstances, and may have the same technical effects.
Further, in the embodiment of the present invention, the first end of the water pump 10 is communicated with the water outlet, one end of the instant heating type steam generator 8 is communicated with the second end of the water pump 10, the other end of the instant heating type steam generator 8 is provided with an air outlet for discharging steam and sewage, and the instant heating type steam generator 8 is in communication connection with the water pump 10.
The instant heating type steam generation system is provided with a steam mode and a descaling mode. The steam mode is to generate steam in the normal cooking process, and the descaling mode is to remove scale from the interior of the instant heating type steam generator 8. Specifically, when the user feels that the instant heating type steam generating system needs to be descaled, the descaled mode of the instant heating type steam generating system needs to be started, and of course, the starting mode is not limited in this embodiment, for example, the instant heating type steam generating system may be started by a descaled button of a touch control screen, or the instant heating type steam generating system may be started by a descaled button separately provided on the instant heating type steam generating system, and those skilled in the art may change according to practical situations. After the start, in the descaling mode, the water pump 10 firstly conveys the descaling water in the clean water tank 1 to the instant heating type steam generator 8, and after the instant heating type steam generator 8 heats the descaling water, the water pump 10 operates again, so that the exhaust port of the instant heating type steam generator 8 can discharge sewage with scale outwards.
In an alternative embodiment, in the steam mode, the water pump 10 delivers clean water from the clean water tank 1 to the instant steam generator 8, and after the instant steam generator 8 is operated, the other end of the instant steam generator 8 discharges steam. Likewise, the starting mode of the steam mode in this embodiment is not limited, for example, the steam mode may be started by a steam button of a touch control screen on the instant heating type steam generating system, or may be started by a steam button separately provided on the instant heating type steam generating system, and those skilled in the art may change according to practical situations.
The descaling mode in this embodiment will be described in detail.
In order to solve the descaling problem of the instant heating type steam generator 8, a user can add descaling water into the clean water tank 1, or can put a descaling agent into the clean water tank according to a certain proportion to prepare descaling water, then the descaling water in the clean water tank 1 is conveyed into the instant heating type steam generator 8 through the water pump 10, and after the instant heating type steam generator 8 is heated, scale in the instant heating type steam generator 8 can be slowly softened and shed. After a while, the water pump 10 is operated again, and because of the structural limitation of the instant heating type steam generator 8, no waste water discharge pipe is provided, water enters from one end of the instant heating type steam generator 8, and steam comes out from the other end of the instant heating type steam generator 8, so that the other end of the instant heating type steam generator 8 can directly discharge sewage with scale. In this way, the instant heating steam generator 8 can be conveniently descaled and cleaned by a user.
So configured, since the instant heating type steam generator 8 has no waste water discharge pipe due to the structural limitation, water enters from one end of the instant heating type steam generator 8, and the other end of the instant heating type steam generator 8 is usually used only for discharging steam, while the instant heating type steam generator 8 of the present embodiment directly discharges sewage with scale by discharging the other end of the instant heating type steam generator 8, the other end of the instant heating type steam generator 8 is an outlet with dual functions, so that steam can be discharged outwards, and sewage with scale can be discharged outwards. The technician does not need to additionally separately provide a drain for discharging scale from the instant steam generator 8, so that modeling costs can be saved.
In an alternative embodiment, the instant heating steam generating system further comprises a timing device in communication with the water pump 10, and in the descaling mode the instant heating steam generator 8 heats the inside descaling water and the temperature of the descaling water in the instant heating steam generator 8 is detected by the temperature detecting device. When the temperature detection device detects that the temperature of the descaling water in the instant heating type steam generator 8 reaches the preset temperature and the timing device detects that the descaling water is kept at the preset temperature for a preset time period, the water pump 10 is started, so that the other end of the instant heating type steam generator 8 discharges sewage with scale. That is, when the temperature of the descaling water reaches a preset temperature, the timing device is controlled to obtain the actual duration of the descaling water maintained at the preset temperature. As for the manner in which the instant heating type steam generator 8 maintains the temperature of the descaling water, PID may also be employed for adjustment. In the present embodiment, the manner in which the temperature of the descaling water is maintained by the instant heating type steam generator 8 is not limited, and may be changed according to the actual situation by those skilled in the art, and the same technical effects may be achieved. When the actual time length is greater than or equal to the preset time length, the water pump 10 is controlled to be started, so that the instant heating type steam generator 8 discharges sewage with scale.
By arranging the timing device, when the descaling water with the descaling agent is heated to the optimal temperature, the timing device can detect the actual reaction time of the descaling water and the scale in the instant heating type steam generator 8 in real time, so that the descaling water with the descaling agent can be ensured to fully react with the scale, and after a certain time period, the scale in the instant heating type steam generator 8 can be slowly softened and shed, so that the removal degree of the scale in the instant heating type steam generator 8 can be improved.
The connection mode, the setting position and the working process of the water level detecting device in the present embodiment are explained in detail as follows.
In an alternative embodiment, a water level detection device is provided in the instant steam generator 8, which is in communication with the water pump 10. In the actual working process, when the water pump 10 is used for conveying the descaling water or the purified water into the instant heating type steam generator 8, the actual water level in the instant heating type steam generator 8 can be obtained through the water level detection device. When the actual water level in the instant heating type steam generator 8 reaches the preset water level, the water pump 10 is controlled to stop operating.
When the water pump 10 supplements water to the instant heating type steam generator 8, the actual water level in the instant heating type steam generator 8 can be detected in real time, and water is prevented from overflowing from the instant heating type steam generator 8 due to excessive water during water supplementing, so that the normal operation of the instant heating type steam generator 8 is ensured.
In the present embodiment, the water level detecting means may be a float-type water level gauge, a pressure-type water level gauge, an ultrasonic water level gauge, or the like. Specifically, the design principle of the float type water level gauge is that the float senses the lifting of the water level, and a common water level gauge with a recording structure is driven in a mechanical mode, so that the float type water level gauge is widely applied or is a mechanical water level gauge at present. The float type water level gauge has the advantages of high measurement precision, good stability, mature technology, most extensive application, no temperature drift and time drift influence and the like.
The pressure type water level gauge is used for measuring the water level by a pressure sensor according to the hydrostatic pressure principle that the pressure is in direct proportion to the water depth. The pressure type water level score is divided into two types, namely a piezoresistive type water level score; the other is a bubble type water level gauge. Although the pressure sensor collects signals and analyzes data to obtain the water level, the pressure sensor of the piezoresistive water level gauge needs to be installed under water, the pressure sensor of the bubble water level gauge is installed inside an onshore instrument, and the whole water level measurement process is realized by blowing air into water through an air blowing pipe.
The ultrasonic water level meter is one kind of reflecting water level meter, and adopts the principle that sound wave is reflected by different interfaces to measure water level, and is divided into two main types of gas medium type and liquid medium type.
Of course, the present embodiment is merely illustrative of a specific type of the water level detecting device, but is not limited thereto, and those skilled in the art may vary according to actual circumstances, and may have the same technical effects.
In an alternative embodiment, a temperature detection device is provided in the instant steam generator 8, which is in communication with the water pump 10. In the actual descaling process, since the instant heating type steam generator 8 needs to heat the descaling water inside, when the temperature detection device detects that the temperature of the descaling water in the instant heating type steam generator 8 reaches the preset temperature, it is indicated that the scale can just fully react with the descaling water at the preset temperature. After the reaction is completed, the water pump 10 is controlled to be started, so that the sewage with scale is discharged outwards from the exhaust port of the instant heating type steam generator 8.
By arranging the temperature detection device, the actual temperature of the descaling water in the instant heating type steam generator 8 can be detected in real time, so that the descaling water with the descaling agent can be heated to the optimal temperature, the descaling water with the descaling agent is ensured to fully react with the scale, and after the instant heating type steam generator 8 is heated, the scale in the instant heating type steam generator 8 can be slowly softened and falls off, so that the removal efficiency of the scale can be improved.
In an alternative embodiment, the descaling mode ends when the temperature detection means detects that the internal temperature of the instant steam generator 8 reaches a dangerous temperature. During operation, when the descaling water in the clean water tank 1 is completely pumped into the instant heating type steam generator 8, the descaling water in the instant heating type steam generator 8 is smaller and smaller along with continuous heating of the instant heating type steam generator 8 and outward discharge of scale, and when the descaling water in the instant heating type steam generator 8 is not available, the instant heating type steam generator 8 is in a dry heating state, and the internal temperature of the instant heating type steam generator 8 is higher and higher. Therefore, when the temperature detecting device detects that the internal temperature of the instant heating type steam generator 8 reaches the dangerous temperature, it indicates that the instant heating type steam generator 8 is already in the dry heating state, so that the descaling mode needs to be ended, the instant heating type steam generator 8 is stopped, the instant heating type steam generator 8 is prevented from being damaged due to dry heating, and the safety of the instant heating type steam generating system is improved.
In an alternative embodiment, the instant heating type steam generation system further comprises a prompting device which is in communication connection with the temperature detection device; when the temperature detection device detects that the internal temperature of the instant heating type steam generator 8 reaches the dangerous temperature, the prompting device sends out a prompting signal which is used for indicating that the water purifying tank 1 is lack of water.
After the prompt device is arranged, when the instant heating type steam generator 8 is in a dry heating state, a prompt signal can be sent out, and after the user senses the prompt signal, if a large amount of water scale still exists in the instant heating type steam generator 8 or the water scale is not removed, the water purifying tank 1 can be timely supplemented with the descaling water, so that the normal operation of the descaling mode in the instant heating type steam generator 8 is ensured. Alternatively, after sensing the alert signal, the user may ignore the alert signal if it is found that the scale in the instant steam generator 8 has been removed.
In an alternative embodiment, the instant heating type steam generation system further comprises a switch valve assembly 4, and the water inlet module may comprise a water pump 10, the switch valve assembly 4 and the water inlet pipe 3. The switch valve assembly 4 is provided with a water inlet end 11, a water outlet end and an air inlet end 2, wherein the water inlet end 11 is communicated with the water outlet through the water inlet pipe 3, and the water outlet end is communicated with the first end of the water pump 10. In the drying mode, the instant heating type steam generator 8 is heated to a drying temperature, the water inlet end 11 of the switching valve assembly 4 is closed, the water outlet end and the air inlet end 2 are opened, and the water pump 10 pumps residual water in the instant heating type steam generator 8 and discharges the water to the outside. In the present embodiment, the on-off valve assembly 4 may be a three-way valve or two-way valves in parallel, and of course, the specific type of the on-off valve assembly 4 is not limited, and the present embodiment is merely illustrative, and those skilled in the art may change according to actual situations, and may have the same technical effects.
In order to prevent that water in the pipeline can not be discharged cleanly in time after steaming is finished each time, the instant heating type steam generation system is not used for producing moss and breeding bacteria for a long time to bring hidden danger to the health of consumers and the service life of the steaming and baking box, the switch valve assembly 4 is adopted, the air inlet end 2 of the switch valve assembly 4 is opened after the user finishes using each time, the water pump 10 can extract air, water in the whole pipeline can be discharged outwards through the other end of the instant heating type steam generator 8, and then the instant heating type steam generation system can be dried quickly, so that the sanitation and the health of the water are ensured when steam is produced.
In an alternative embodiment, the instant heating type steam generating system further comprises a water outlet pipe 5 and a water adding pipe 15, wherein one end of the water outlet pipe 5 is communicated with a water outlet end, and the other end of the water outlet pipe 5 is communicated with a first end of the water pump 10; in the drying mode, the water pump 10 pumps the residual water in the water outlet pipe 5. One end of the water adding pipe 15 is communicated with one end of the instant heating type steam generator 8, and the other end of the water adding pipe 15 is communicated with the second end of the water pump 10; in the drying mode, the water pump 10 pumps residual water in the water feed pipe 15.
Likewise, in order to prevent that the water in the pipeline cannot be discharged cleanly in time after steaming is finished each time, the instant heating type steam generation system is not used for producing moss and breeding bacteria for a long time to bring hidden danger to the health of consumers and the service life of the steaming and baking box, the switch valve assembly 4 is adopted, the air inlet end 2 of the switch valve assembly 4 is opened after the user finishes using each time, the water pump 10 can pump air, so that the water in the whole pipeline can be discharged outwards through the other end of the instant heating type steam generator 8, and then the instant heating type steam generation system can be dried rapidly, and the sanitation and the health of the water are ensured when steam is produced.
Example 4
In a fourth aspect, the present invention also provides an embedded cooking apparatus, comprising: an instant heating steam generation system in any of the above embodiments.
In order to solve the descaling problem of the instant heating type steam generator 8 in the embedded cooking equipment, a user can add descaling water into the clean water tank 1, or can put a descaling agent into the clean water tank according to a proportion to prepare descaling water, then the descaling water in the clean water tank 1 is conveyed into the instant heating type steam generator 8 through the water pump 10, and after the instant heating type steam generator 8 is heated, scale in the instant heating type steam generator 8 can be softened slowly and fall off. After a while, the water pump 10 is operated again, and because of the structural limitation of the instant heating type steam generator 8, no waste water discharge pipe is provided, water enters from one end of the instant heating type steam generator 8, and steam comes out from the other end of the instant heating type steam generator 8, so that the other end of the instant heating type steam generator 8 can directly discharge sewage with scale. In this way, it is possible to facilitate the descaling and cleaning of the instant heating type steam generator 8 in the built-in cooking apparatus by the user. This allows the use of the instant steam generator 8 in an embedded cooking device to be fully achieved. In an alternative embodiment, the built-in cooking apparatus further comprises a cabinet 7, a cooking liner 21 and a chassis 14. Specifically, a cooking liner 21 is provided inside the case 7, and an instant heating type steam generation system is provided on the case 7. The through hole 22 is arranged on the inner wall of the cooking inner container 21, and the through hole 22 is communicated with the exhaust port at the other end of the instant heating type steam generator 8. The bottom plate 14 is disposed at the bottom of the cooking inner container 21, and the bottom plate 14 is located below the through hole 22. In the descaling mode, when the other end of the instant heating type steam generator 8 discharges sewage with scale, the sewage directly flows into the chassis 14 through the through hole 22. The bottom plate 14 may be a grease tray, and can receive oil rubbish and residual water generated in the cooking process of the cooking inner container 21 and sewage with scale. Therefore, the use function of the grease tray can be improved, and a container special for receiving sewage is not required to be additionally arranged, so that two purposes are achieved.
By arranging the bottom plate 14 at the bottom of the cooking inner container 21, the lower part of the through hole 22 in the cooking inner container 21 ensures that the sewage containing the scale remover and the scale after the instant heating type steam generator 8 heats and softens the scale can not flow into the cooking inner container 21, but directly flow into the bottom plate 14. After the descaling is finished, the user only needs to pour the waste water in the chassis 14 and clean the lower chassis 14. The problem that water with a scale remover in the prior art flows to the waste water box through the drain hole at the bottom of the cooking inner container 21 is solved, and after each scale removal, a user needs to clean the cooking inner container 21 to carry out pain points of food cooking in the next step. And the waste water box is also omitted, so that the product cost is reduced to a certain extent.
In an alternative embodiment, in the steam mode, the exhaust port at the other end of the instant heating type steam generator 8 is fed with steam through the through hole 22 into the cooking inner 21. Further, an intake pipe 17 may be provided, one end of the intake pipe 17 communicates with the exhaust port, and the other end of the intake pipe 17 is inserted into the through hole 22.
In an alternative embodiment, the built-in cooking apparatus further comprises a top heating tube 6 and a bottom heating tube 13. Specifically, the top heating tube 6 is provided on the top outer side wall of the cooking inner container 21, and the bottom heating tube 13 is provided on the bottom outer side wall of the cooking inner container 21. When the steam mode is just entered, the top heating tube 6 and the bottom heating tube 13 rapidly preheat the cooking liner 21.
In order to prevent that water in the pipeline can not be discharged cleanly in time after steaming is finished each time, the embedded cooking equipment is free of moss and bacteria for a long time, hidden danger is brought to the health of consumers and the service life of the embedded cooking equipment, the switch valve assembly 4 is adopted, the air inlet end 2 of the switch valve assembly 4 is opened after the user finishes cooking each time, the water pump 10 can pump air, water in the whole pipeline can be discharged to the bottom of the cooking liner 21 through the through hole 22, and then the bottom heating pipe 13 is utilized for quick drying, so that the sanitation and the health of water are ensured when the embedded cooking equipment is used for steaming food.
In an alternative embodiment, the embedded cooking device is any one of an embedded steam box and an embedded steam box.
The overall workflow of the built-in cooking apparatus is described in detail as follows:
as shown in fig. 1, 2 and 3: when the whole embedded cooking apparatus is in a standby state, a user puts the cooked food on a grill 18 or a steaming tray 19 of a cooking liner 21 after preparing the cooked food, checks whether the purified water in the purified water tank 1 is sufficient, and can select a steaming mode, a set time and a temperature through a control panel 20 of the embedded cooking apparatus, or can select a steaming automatic menu for one-key operation. Of course, the control panel 20 of the built-in cooking apparatus may be combined with a touch control screen on the instant heating steam generation system. In this embodiment, the embedded cooking device is exemplified as a steaming oven.
Clicking to start, the steaming oven enters a preheating stage, the top heating tube 6 and the bottom heating tube 13 rapidly preheat the cooking liner 21 of the steaming oven, and the steaming oven enters a heating stage after the temperature of the temperature sensing needle 16 in the cooking liner 21 reaches 60 ℃. At this time, the top heating tube 6 stops operating, and the bottom heating tube 13, the instant steam generator 8, and the on-off valve assembly 4 start operating. Meanwhile, the air inlet end 2 is closed, the water pump 10 pumps the purified water in the purified water tank 1 into the instant heating type steam generator 8, the temperature detection device in the instant heating type steam generator 8 carries out PID algorithm calculation on the sensed temperature, and the temperature detection device can be a temperature sensing bag 9.
Such as: the temperature sensed by the temperature sensing bulb 9 reaches 200 ℃, the switch valve assembly 4 is opened, the switch valve assembly 4 can be a three-way electromagnetic valve, and the water pump 10 starts pumping water. When the temperature sensed by the temperature sensing bag 9 is reduced to 80 ℃, the three-way electromagnetic valve and the water pump 10 are closed, water pumping is stopped, and the circulation is performed.
If the program or the whole machine is abnormal, for example, the temperature sensed by the temperature sensing bag 9 reaches 220 ℃, the temperature sensing bag 9 sends a signal to the main board 12 of the steaming oven, so that the bottom heating pipe 13 and the instant heating type steam generator 8 stop working, power-off protection is carried out, and the high temperature of the instant heating type steam generator 8 is prevented, thereby causing hidden danger to the electric safety of the steaming oven and the personal and property safety of a user.
In the steam mode, steam generated by the instant heating type steam generator 8 reaches the cooking inner container 21, and the temperature sensing bag 9 transmits the sensed temperature of the cooking inner container 21 to the steam oven, so that the steam oven performs PID algorithm calculation. Such as:
the temperature sensed by the temperature sensing bulb 9 reaches 90 ℃, the bottom heating tube 13 works for 10 seconds, stops for 50 seconds, the duty ratio works, the three-way electromagnetic valve, the water pump 10 and the instant heating type steam generator 8 work, and the three-way electromagnetic valve, the water pump 10 and the instant heating type steam generator continuously provide high-temperature steam for the cooking liner 21. When the actual temperature sensed by the bulb 9 reaches the set target temperature: after 100 ℃, the cooking liner 21 enters a temperature maintaining stage.
When the set target temperature is about to be reached, the water inlet end 11 of the three-way electromagnetic valve is closed, the air inlet end 2 is opened, the water pump 10 pumps residual water in the water outlet pipe 5, the water adding pipe 15 and the instant heating type steam generator 8 to be discharged to the bottom of the cooking liner 21, and then the water is quickly dried by the bottom heating pipe 13, so that the situation that a user does not use the steaming oven for a long time, residual water in a pipeline system is caused, moss and bacteria are generated, and the food is steamed, and the physical health of the user is affected.
When the steam oven is required to be descaled regularly, a user adds purified water to the height of a descaled water line of the clean water tank 1, sends a descaled instruction, and puts the descaler into the steam oven according to a proportion so that the descaler is fully dissolved in the clean water tank 1. After 6 minutes, the air inlet end 2 of the three-way electromagnetic valve is closed, the water inlet end 11, the water pump 10 and the instant heating type steam generator 8 start to work, and the water pump 10 pumps the descaling water with the descaling agent in the clean water tank 1 and flows into the instant heating type steam generator 8. And the water level of the instant heating type steam generator 8 is judged in real time through the water level detection device.
The middle upper part of the instant heating type steam generator 8 is provided with a temperature sensing needle 16, and when the mixed water with the descaling agent is heated to about 90 ℃ through the temperature change sensed by the temperature sensing needle 16, scale in the instant heating type steam generator 8 can be slowly softened and shed. After 5 minutes, the water pump 10 starts to operate, and the sewage containing scale in the instant heating type steam generator 8 is discharged into the grease pan at the bottom of the cooking liner 21.
When the water extraction of the instant heating type steam generator 8 containing scale is finished, the instant heating type steam generator 8 is still heated, and at the moment, the temperature of the temperature sensing needle 16 of the instant heating type steam generator 8 is increased to a set value, so that the air inlet end 2 of the three-way electromagnetic valve can be controlled to be closed, and the water inlet end 11, the water pump 10 and the instant heating type steam generator 8 continue to circularly work until the descaling mode is finished.
However, when the user does not pay attention to that the water in the clean water tank 1 containing the descaling agent is completely pumped, the temperature detected by the temperature sensing needle 16 of the instant heating type steam generator 8 rises to 220 ℃, and at the moment, the prompting device reports that the water tank is lack of water, and the descaling mode is finished.
Therefore, the feasibility problem that the instant heating type steam generator 8 is applied to the embedded steaming oven is solved, compared with a traditional boiling type steam generator system, the intelligent steam oven has the advantages of small size, less scale, low power, large steam quantity, high steam generation speed, low steam water content, short waterway pipeline, low cost and the like, and compared with the traditional boiling type steam generator system, the intelligent steam oven has the advantages of reducing the number of important components such as a waste water pump 10, a water pump 10 fixing box and a water level sensing needle, and greatly improving the reliability and market competitiveness of products.
