Detailed Description
In order to make the above objects, technical solutions and advantages of the present invention more comprehensible, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments of the present invention described herein are only some of the embodiments constituting the present invention, which are intended to be illustrative of the present invention and not limiting of the present invention, and the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, a schematic perspective view of a cooking appliance according to the present invention is shown, where the cooking appliance includes a heating chamber 1, a heating device 2 disposed in the heating chamber 1, and a steam generator 3 disposed outside the heating chamber 1, the heating device 2 has multiple sets of indoor heat sources distributed in parallel, and the steam generator 3 is provided with a steam heater 31 and a thermostat 32 in a matching manner.
Specifically, the heating device 2 may have a plurality of sets of indoor heat sources distributed in parallel, for example, the heating device 2 may include an upper heating tube 21 and a lower heating tube 22 distributed in parallel. After the multiple groups of indoor heat sources are electrified and run, the temperature in the heating chamber 1 can rise rapidly, and a first thermistor for detecting the temperature T of the heating chamber can be arranged on the wall surface in the heating chamber 1 and/or an external air guide cover. When the heating chamber temperature T detected by the first thermistor rises to a certain temperature, the cooking appliance controls the steam heater 31 to be energized and raised, and the power supply of the cooking appliance may be cut off by the thermostat 32 operated by the rising of the temperature of the steam heater 31, or the heating appliance may be energized only by all the indoor heat sources, that is, the heat sources of the heating device 2.
Unlike the prior art, the present invention will aim to ensure that the energization of all indoor heat sources will be effectively shut off during the above-described shut-off process, or rather, during the entire energization of the steam heater 31, thereby ensuring that abnormal overcurrent does not occur in the cooking appliance. Therefore, the invention provides a heat source electrifying cutting-off method, which comprises the following steps:
s1: judging whether the temperature T of the heating chamber rises to a first set temperature T1;
s2: if yes, all the first heating relays 41 are turned off, wherein each group of indoor heat sources of the heating device 2 is connected in series to correspond to at least one group of the first heating relays 41; if not, returning to the step S1;
s3: judging whether the temperature T of the heating chamber rises to a second set temperature T2, wherein T2 is more than T1;
s4: if so, turning off a second heating relay 42 which controls the heating device 2 in series; if not, returning to the step S3;
s5: the third steam relay 43 for controlling the energization of the steam heater 31 to raise the temperature is turned on to operate the thermostat 32 to cut off the power supply of the electric appliance or to cut off the energization of only the heat sources of all the indoor heat sources.
Specifically, in the present invention, even if the heating chamber temperature T rises to the second set temperature T2 due to the short circuit of the individual first heating relay 41, when T is equal to or greater than T2, since the second heating relay 42 for controlling the heating device 2 in series is turned off before the third steam relay 43 is turned on, any one of the indoor heat sources is not turned on simultaneously with the steam heater 31.
Therefore, by the heat source power-on cutting-off method, abnormal overcurrent does not occur when the heat source power-on cutting-off device cuts off the power supply of the heat source, and the operation of the electrical equipment is ensured to be safer and more reliable.
It should be noted that, of course, in step S5, the purpose of opening the third steam relay 43 is to enable the steam heater 31 to be energized so that it can be quickly warmed up to the third set temperature T3, and then the thermostat 32 is operated to cut off the power supply of the electric appliance, or to cut off the energization of the heat sources of all the indoor heat sources alone, so that the steam generator 3 is not supplied with water during the energization warming of the steam heater 31.
The following description of the heat source energizing shut-off device will be provided in more detail by way of example for the purpose of facilitating a further understanding of the technical solutions of the present application by those skilled in the art. Meanwhile, for convenience of description, the following embodiments of the present invention will be described with reference to the example of "the upper heating tube 21 and the lower heating tube 22 in which the indoor heat sources are distributed in parallel", but those skilled in the art will understand that other indoor heat sources may be provided in more ways.

Of course, if the thermostat 32 is of a type that can be automatically reset, the thermostat 32 can be automatically reset after the operating temperature of the thermostat 32 is reduced below the third set temperature T3, but the energization of all indoor heat sources and thus the electrical power supply will remain in an effectively shut-off state.
Example 2
Referring to fig. 3, the present invention provides another heat source energizing and cutting device for cutting and controlling an indoor heat source, wherein the indoor heat source is an upper heating tube 21 and a lower heating tube 22 distributed in parallel, and the heat source energizing and cutting device comprises:

Specifically, referring to fig. 3, the first heating relay 411 of the first group is RL5 that is simultaneously disposed at the front end of the upper heating tube 21 and the front end of the steam heater 31, and commonly controls the energization of the upper heating tube 21 and the energization of the steam heater 31; the second group of first heating relays 412 are RL6 for independently controlling the energization of the lower heating tubes 22 in series; the second heating relay 42 is RL1 for controlling the upper heating tube 21 and the lower heating tube 22 to be energized together; the third steam relay 43 includes, in addition to the RL5 provided at the front end of the steam heater 31, the RL7 provided at the rear end of the steam heater 31; after the thermostat 32 is operated, the temperature fuse of the steam generator shown in fig. 3 is melted, and thus the heat sources of all indoor heat sources are powered on and even the power of the electric appliances is effectively cut off.
Compared with embodiment 1, embodiment 2 omits RL8, which is advantageous in reducing the heat source energization cutoff device cost. Wherein, RL5 is used as a first relay when RL1 is in the ON state and is used as a third relay when RL1 is in the OFF state. It will be understood by those skilled in the art that the upper heating tube 21 and the lower heating tube 22 may be replaced with equivalent ones.
Example 3
Referring to fig. 4, the present invention provides another heat source energizing and cutting device for cutting and controlling an indoor heat source, wherein the indoor heat source is an upper heating tube 21 and a lower heating tube 22 distributed in parallel, and the heat source energizing and cutting device comprises:
an indoor heat source control loop, which is controlled by a second heating relay 42, wherein one end of the second heating relay 42 is connected in series with the indoor heat source, and the other end is connected in series with the thermostat 32, the front end of the upper heating pipe 21 is connected in series with a first group of first heating relays 411, and the lower heating pipe 22 is connected in series with a second group of first heating relays 412;
the heat source electrifying and cutting-off loop comprises the thermostat 32 and further comprises a steam heater 31 and a first group of third steam relays 431 which are sequentially arranged in series at the rear end of the first group of first heating relays 411 and the front end of the upper heating pipe 21 in series, wherein the first group of first heating relays 411 and the first group of third steam relays 431 form the third steam relays 43 together;
the inversion loop is arranged in parallel with the main control loop, wherein the main control loop comprises the indoor heat source control loop and the heat source electrifying cutting-off loop.

Here, although the inverter circuit may be set in embodiment 2 as compared with embodiment 3, the limitation of embodiment 2 does not exclude that the thermostat 32 is not included in the inverter circuit, and the inverter circuit is likely to be cut off even when the thermostat 32 is operated, that is, the "electric power supply" is likely to be cut off in step S5. In embodiment 3, the main control circuit is set, and the inverter circuit and the main control circuit are defined to be arranged in parallel, so the inverter circuit will not include the thermostat 32, and therefore the inverter side where the inverter circuit is located will not be cut off when the thermostat 32 is operated, i.e. "the heat source power on only all indoor heat sources is cut off" in step S5. Furthermore, embodiment 3 still makes it possible to restore the heat source energization of all indoor heat sources by means of the variable frequency power source to ensure that the cooking appliance can continue to be used.
Therefore, when the cooking appliance is a product integrating functions of baking, steaming and microwave heating, such as a micro-steaming and baking integrated machine, the function of the micro-steaming and baking integrated machine can be ensured to be normally used, wherein the heating mode of the indoor heat source of the cooking appliance can comprise microwave heating.

When the inverter circuit is also connected to the control board 5, the control board 5 is not turned off when the thermostat 32 is operated, so that the normal power supply of the inverter circuit is ensured, corresponding to the "power supply of heat sources only to all indoor heat sources" in step S5. In both embodiments 1 and 2, it is not ensured that the power supply to the control board 5 is not interrupted.
