Description

  The present invention includes high-frequency generating means for outputting a high frequency in a heating chamber that houses an object to be heated, and a steam supply unit that supplies steam to the heating chamber, and supplies at least one of the high frequency and the steam to the heating chamber. The present invention relates to a high-frequency heating apparatus with a steam generation function that heats an object to be heated.

High-frequency heating devices that heat the object to be heated with high frequency include a single-function type that only has high-frequency heating and a composite function type that has an oven function added. These high-frequency heating devices contain the object to be heated. In the heating chamber, the juice or debris of the object to be heated may adhere to the heating chamber, and if left untreated, sticking or scorching will occur and the heating chamber will become dirty. . Such attached dirt not only causes a problem in maintaining the heating chamber in a sanitary manner, but also causes smoke and the like during high-frequency heating. For this reason, the heating chamber is frequently cleaned or the dirt in the heating chamber is removed by a high-temperature burn-out function provided in the heating device itself. However, in recent years, heating steam is further supplied into the heating chamber. There has been proposed a high-frequency heating device with a steam generation function that has a function of adding a steam supply mechanism and capable of cleaning the heating chamber with steam (see, for example, Patent Document 1).

  As an example of the basic heating operation by the high-frequency heating device 100 having the above-described configuration, an operation during steam heating will be described.

  When a steam heating mode is selected from various heating modes such as a high-frequency heating mode, a steam heating mode, and an oven heating mode and the start switch 65 is pressed, as shown in FIG. When the evaporating dish heater 37 is turned on, water in the evaporating dish 35 supplied from the water tank 43 by the pump 55 is heated, and steam S is generated. The steam S rising from the evaporating dish 35 is sucked into the central portion of the circulation fan 17 from the intake vent hole 29 provided in the substantially central portion of the partition plate 27, and passes through the circulation fan chamber 25 to surround the partition plate 27. It blows out toward the inside of the heating chamber 11 from the ventilation hole 31 for ventilation provided in the part.

  The blown-out steam is stirred in the heating chamber 11 and again sucked into the circulation fan chamber 25 side from the intake vent hole 29 at the substantially central portion of the partition plate 27. Thereby, a circulation path is formed in the heating chamber 11 and the circulation fan chamber 25. The generated steam is guided to the intake vent hole 29 without providing the ventilation vent hole 31 below the position where the circulation fan 17 is disposed on the partition plate 27. Therefore, as shown by the white arrow in the figure, the steam circulates through the heating chamber 11, and the steam is efficiently sprayed on the object to be heated M.

  At this time, since the steam in the heating chamber 11 can be heated by the room air heater 19, the temperature of the steam circulating in the heating chamber 11 can be set to a high temperature. Therefore, so-called superheated steam is obtained, and heating cooking with a burnt surface on the surface of the article to be heated M is also possible.

  When performing high frequency heating, the magnetron 13 is turned on and the stirrer blade 33 is rotated to supply high frequency into the heating chamber 11 while stirring. In the high-frequency heating apparatus 100, high-frequency heat treatment combining steam and high-frequency can be performed.

  The above is the heat treatment procedure including normal steam heating. Next, the heating chamber cleaning function, which is a feature of the present invention, will be described below.

  The operation of the high-frequency heating device 100 when the cleaning mode is selected and executed by the input operation unit 61 will be described with reference to the flowchart shown in FIG.

  When the cleaning switch 81 of the input operation unit 61 is pressed (step 1, hereinafter referred to as S1), an input signal is transmitted from the input operation unit 61 to the control unit 83, and the control unit 83 enters a cleaning mode selection standby state (S2). ). Then, the evaporating dish cleaning mode, the heating chamber cleaning mode, or the deodorizing mode is selected by turning the setting dial 82 in this state. When one of the cleaning modes is selected and the start switch 65 is pressed, operation in the selected cleaning mode is started (S3, S4).

  Here, each cleaning mode will be described with reference to the flowcharts shown in FIGS. 11 and 12.

(Evaporation dish cleaning mode)
First, a cleaning solution in which citric acid is dissolved in water is poured into the evaporating dish 35 (S11). In this state, when the evaporating dish cleaning mode is selected and the start switch 65 is pressed, the evaporating dish 35 is heated by the evaporating dish heater 37, and the cleaning liquid in the evaporating dish 35 is heated to about 100 ° C. in about 30 seconds. (S12). The evaporating dish heater 37 is operated intermittently so as to maintain the temperature of the cleaning liquid at about 80 to 95 ° C. (S13). During this time, water is sent from the water tank 43 by a pump 55 at a constant interval (so that the cleaning liquid in the evaporating dish 35 is not lost) (S14). When a predetermined time (for example, about 20 minutes) elapses to maintain the state of about 80 to 95 ° C. (S15). Thereafter, the temperature is lowered to 50 ° C. (S16), and 1 minute before the end (S17) (for example, about 29 minutes from the start of heating), water can be supplied from the water tank 43 into the evaporating dish 35 by the pump 55, and can be wiped off. The temperature is lowered to about 40 ° C. (S18).

  When a predetermined time (for example, about 30 minutes from the start of heating) has passed (S19), in order to notify the end of the cleaning process, a message indicating the end of cleaning is displayed on the display panel 75 together with a sound, an alarm sound, or the like (S20). After confirming the completion of the above cleaning, the door 21 is opened and the evaporating dish 35 is wiped off with a cloth or the like (S21).

  By performing such an evaporating dish cleaning mode, deposits such as calcium and magnesium adhering to the evaporating dish 35 are decomposed by citric acid and can be reliably and easily removed.

  Note that citric acid that is safe for food hygiene and highly effective in decomposing calcium, magnesium, etc. is suitably used as the cleaning liquid, but is not limited to this, and a surfactant or the like is added to the citric acid solution to obtain an oil component. It is also possible to improve the cleaning performance against dirt, and other cleaning liquids may be used.

(Heating chamber cleaning mode)
When the heating chamber cleaning mode is selected and the start switch 65 is pressed, water is intermittently supplied from the water tank 43 into the evaporating dish 35 by the pump 55 (S31). The evaporating dish heater 37 is intermittently operated so as to maintain the temperature of the water in the evaporating dish 35 at about 100 ° C. to generate steam (S32). Further, the drive motor 23 of the circulation fan 17 is intermittently driven (S33). At this time, the drive motor 23 is driven intermittently, for example, for about 2 seconds per 30 seconds. As a result, the circulating air shown in FIG. 9 is obtained, and the generated steam stays in the heating chamber 11 and is distributed without being biased, so that the steam is condensed on the entire inner surface of the heating chamber 11. During this time, water is sent from the water tank 43 by the pump 55 at regular intervals (so that the water in the evaporating dish 35 does not disappear) (S34).

  Then, after the elapse of a predetermined time of about 3 to 5 minutes (S35), the pump 55 and the drive motor 23 are turned off (S36), and the evaporating dish heater 37 maintains the temperature of the water at about 50 ° C. (S37). One minute before the end (S38) (for example, about 29 minutes from the start of heating), the temperature is lowered to about 40 ° C. where water can be supplied from the water tank 43 into the evaporating dish 35 by the pump 55 and can be wiped off (S39). .

  When a predetermined time (for example, about 30 minutes from the start of heating) has elapsed (S40), in order to notify the end of the cleaning process, a message indicating the end of cleaning is displayed on the display panel 75 together with a sound, an alarm sound, or the like (S41). After confirming the completion of the above cleaning, the door 21 is opened and the evaporating dish 35 is wiped off with a cloth or the like (S42).

  By performing such a heating chamber cleaning mode, dirt such as scattered matter from the heated object M sticking to the inner surface of the heating chamber 11 rises from the inner surface of the heating chamber 11. The dirt can be removed all at once by wiping off the attached dirt in a state where the degree of adhesion with the inner surface of the heating chamber is lowered.

  Thus, according to the high-frequency heating device 100 having the above structure, the control unit 83 controls the steam generation unit 15, the water supply pump 55, the circulation fan 17, and the like based on the signal input to the input operation unit 61. By executing a desired cleaning mode, the inner surface of the heating chamber 11 and the evaporating dish 35 can be cleaned by a simple operation, and without performing complicated work, The evaporating dish 35 can be cleaned very easily and can be kept clean.

  That is, in the evaporating dish cleaning mode, a cleaning liquid made of a citric acid solution is poured into the evaporating dish 35 and heated to a predetermined temperature (about 80 to 95 ° C.), whereby dirt such as calcium and magnesium adhering to the evaporating dish 35 is obtained. Is disassembled. Thereby, the deposits can be reliably and easily removed simply by wiping the evaporating dish 35. Further, in the heating chamber cleaning mode, the inner surface of the heating chamber 11 is condensed with steam, and the evaporating dish heater 37 is energized so as to maintain the condensation, so that dirt attached to the inner surface of the heating chamber 11 can be easily lifted. This makes it easy to wipe off the dirt, thereby making the inner surface of the heating chamber 11 clean.

  In each cleaning mode, after the start switch 65 is pressed, the high-frequency heating apparatus 100 automatically performs cleaning, so that the operator does not always have to monitor the high-frequency heating apparatus 100 and is notified of the end of cleaning. Until then, no restraint. In addition, after cleaning is finished, dirt that was usually difficult to remove is in a state that can be removed very easily, and it can be sufficiently wiped off by lightly wiping without applying force, easily obtaining a good cleaning effect be able to.

  The high-frequency heating device according to the present invention is not limited to the above-described embodiments, and appropriate modifications and improvements can be made without departing from the spirit of the invention.

  As described above, according to the high-frequency heating device of the present invention, a complicated operation is performed by executing the designated cleaning mode based on the signal input to the control unit via the signal input means. In addition, it is very easy to clean the inside of the heating chamber where dirt is attached by keeping the temperature of the evaporating dish high, and at the end, the temperature of the water receiving dish can be lowered by supplying water with a pump. Since the cleaning operation can be performed, the present invention can be applied to a cooking device cleaning method other than using a high frequency as a heating means.
