The utility model provides a pair of household appliance includes container and isolator, and the isolator is formed with gas vent and liquid level restriction face, and inject first cavity between the partly internal surface of liquid level restriction face and container, and first cavity and gas vent are linked together. The isolator can cover the medium, so that the medium is gathered between the liquid level limiting surface and a part of the inner surface of the container to define a first cavity, the space in the first cavity is fixed, the quantity of the medium positioned in the first cavity is limited, and the quantity of the medium to be heated is less influenced by the medium quantity and the medium temperature of the outer area of the isolator.

According to the utility model discloses foretell household appliance can also have following additional technical characterstic:

in the above technical solution, further, the volume of the first chamber is less than or equal to 300 ml.

In the technical scheme, the volume of the first chamber is limited reasonably, so that the volume of the first chamber is less than or equal to 300ml, and effective and reliable structural support is provided for continuously discharging steam. If the volume of the first chamber is more than 300ml, the amount of the medium in the first chamber is large, which increases the time from normal temperature to boiling and generates relatively stable steam, and cannot achieve the purpose of quickly generating high-temperature steam.

In any of the above solutions, further, the distance between the liquid level limiting surface and a part of the inner surface of the container satisfies: 1mm to 20 mm.

The isolator 100 will trap the media, causing the media to pool in the first chamber 110 defined between the level limiting surface and a portion of the interior surface of the vessel 310, since the space in the first chamber 110 is constant, the amount of medium located therein is limited, so that the amount of medium to be heated is less affected by the amount of medium and the temperature of the medium in the region outside the separator 100, in this way, when the household appliance 300 is in operation, most of the heat is absorbed by the medium in the first chamber 110, the medium in the region outside the separator 100, however, absorbs only little heat due to the action of the separator 100, so that by heating the medium in the first chamber 110, the time from normal temperature to boiling of the medium and the generation of relatively stable steam can be greatly shortened, and the temperature rise of the medium in the outer area of the isolator 100 is very small, so that the purpose of quickly generating high-temperature steam can be realized, and the energy loss is avoided.

Further, since the exhaust port 120 is communicated with the first chamber 110, that is, the high-temperature steam generated in the first chamber 110 is exhausted out of the separator 100 through the exhaust port 120, that is, the separator 100 defines a flow path of the generated steam, and has a converging effect on the steam, so that the steam can be concentrated in the area to be cooked, thereby improving the cooking efficiency of the household appliance 300. Further, the isolator 100 forms a liquid level limiting surface, and the liquid level limiting surface can press the medium flowing into the first chamber 110 into a medium layer, so as to increase the contact area between the medium and the heating element 340 of the household appliance 300 under the condition of ensuring a certain medium quantity, thereby being beneficial to quickly generating high-temperature steam and avoiding energy loss.

In detail, by properly defining the volume of the first chamber 110 such that the volume of the first chamber 110 is equal to or less than 300ml, an effective and reliable structural support is provided for the continuous steam discharge. If the volume of the first chamber 110 is greater than 300ml, the amount of the medium in the first chamber 110 is large, which increases the time from normal temperature to boiling and generates relatively stable steam, and cannot achieve the purpose of generating high-temperature steam quickly.

Specifically, the volume of the first chamber 110 is less than or equal to 200 ml; or the volume of the first chamber 110 is less than or equal to 150 ml; or the volume of the first chamber 110 is less than or equal to 100 ml; or the volume of the first chamber 110 satisfies 80ml to 150ml, etc., which are not enumerated herein.

In detail, the distance between the liquid level limiting surface and a part of the inner surface of the container 310 is reasonably limited, so that the distance is 1mm to 20mm, the phenomenon that the amount of the medium to be heated is too small due to the fact that bubbles generated by boiling of the medium are full of the first chamber 110 and local temperature abnormality is easily generated even dry burning is generated can be avoided, and the use safety and reliability of the household appliance 300 can be guaranteed. If the distance between the liquid level limiting surface and a part of the inner surface of the container 310 is less than 1mm, bubbles generated by medium boiling fill the first chamber 110, and local temperature abnormality and even dry burning are easy to occur; if the distance between the liquid level limiting surface and a part of the inner surface of the container 310 is greater than 20mm, the amount of the medium in the first chamber 110 is large, which increases the time from normal temperature to boiling of the medium and generates relatively stable steam, and thus the purpose of generating high-temperature steam rapidly cannot be achieved.

Specifically, the spacing between the liquid level limiting surface and a portion of the interior surface of the vessel 310 satisfies: 2mm to 18 mm; or the spacing between the liquid level limiting surface and a portion of the interior surface of the vessel 310 is such that: 3mm to 7 mm; or the spacing between the liquid level limiting surface and a portion of the interior surface of the vessel 310 is such that: 4mm to 15mm, etc., not to mention one by one.

If the area of the region surrounded by the outer edge of the liquid level limiting surface is less than 5000mm²The heated area of the medium in the first chamber 110 is small, which increases the time from normal temperature to boiling and generates relatively stable steam, and thus the purpose of generating high-temperature steam quickly cannot be achieved.

Specifically, the area of the region surrounded by the outer edge of the liquid level limiting surface satisfies: 6000mm²To 30000mm²(ii) a Or the area of the area enclosed by the outer edge of the liquid level limiting surface satisfies the following conditions: 8000mm²Up to 20000mm²Etc., not to mention them.

The isolation plate 160 is disposed around the isolation portion 150, a gap 170 is formed between the isolation portion 150 and the isolation plate 160, and the gap 170 is communicated with the exhaust port 120, so that steam generated after the medium is boiled can flow to the exhaust port 120 through the gap 170 and then flows out of the isolator 100. The gap 170 is configured to ensure that the medium levels in the inside of the separator 100 and the outside of the separator 100 are the same, so that the space for accommodating the medium in the separator 100 is reduced, and thus, the amount of the medium in the inside of the separator 100 is reduced, thereby greatly shortening the time for the medium in the first chamber 110 to boil from normal temperature and generate relatively stable steam. And the structural arrangement makes the medium in the first chamber 110 less affected by the temperature when the medium level in the outer region of the isolator 100 is high, so that the time from normal temperature to boiling of the medium and the generation of relatively stable steam cannot be obviously prolonged.

In addition, the bottom wall of the isolation portion 150 and the isolation plate 160 define at least part of a liquid level limiting surface, that is, the bottom wall of the isolation portion 150 and the isolation plate 160 cooperate to press the medium flowing into the first chamber 110 into a medium layer, so that the contact area between the medium and the heating element 340 is increased under the condition that the medium quality is ensured to be certain, high-temperature steam is favorably and quickly generated, and the energy loss is avoided.

If the distance between the partition 150 and the partition plate 160 is less than 0.5mm, the gas is not discharged in time, which may cause the pressure generated when the medium is boiled to be too large to lift the separator 100. If the interval between the partition 150 and the partition plate 160 is greater than 10mm, the amount of the medium that cannot be effectively heated is large, resulting in that heat of the steam is absorbed and the generation of the steam is slow.

If the area of the slit 170 is less than 200mm²In this case, the gas is not discharged in time, which may cause the pressure generated when the medium is boiled to be too high to lift the separator 100. If the area of the gap 170 is larger than 2000mm²The amount of the medium that cannot be heated effectively is large, resulting in the heat of the steam being absorbed and the steam being generated slowly.

The heating element 340 supplies heat to the first chamber 110, and the heating element 340 may also supply heat to the first chamber 110 and the third chamber 320.

Specifically, the average heating power of the heating cycle of the heating member 340 satisfies: 150W to 1800W. The average heating power of the heating cycle by reasonably setting the heating member 340 satisfies: 150W to 1800W, the energy consumption of the heating element 340 can be reduced under the condition that the heat generated by the heating element 340 can effectively heat the medium in the first chamber 110, thereby realizing rapid steam discharge.

Wherein, the heating period refers to that the heating member 340 stops working for a second preset time after working for a first preset time. For example, the first preset time is 17s and the second preset time is 15s, for example, the heating element 340 works for 17s, stops for 15s, then works for 17s, and then stops for 15s, which is two heating cycles; as another example, the first predetermined time is 16s, the second predetermined time is 16s, for example, the heating element 340 is operated for 16s, stopped for 16s, then operated for 16s, and then stopped for 16s, which is two heating cycles, and so on, which are not listed here.

Specifically, the average heating power of the heating cycle of the heating member 340 satisfies: 200W to 1000W; the average heating power of the heating cycle of the heating member 340 satisfies: 500W to 1000W; or the average heating power of the heating cycle of the heating member 340 satisfies: 600W to 900W; or the average heating power of the heating cycle of the heating member 340 satisfies: 700W to 800W, etc., which are not enumerated herein.

Example 16:

as shown in fig. 3 and 7, according to an embodiment of the present invention, including the features defined in any of the above embodiments, and further: the household appliance 300 further comprises: a material containing member 350, at least a portion of the material containing member 350 being received in the container 310, the material containing member 350 being positioned above the separator 100.

In detail, by providing the material container 350, the material can be put into the material container 350 to boil the material in the material container 350 using the steam discharged from the exhaust port 120 of the separator 100. Wherein, the material holds 350 and is equipped with concave cavity, and the bottom surface of this concave cavity forms the material and holds the portion, will treat that the culinary art material is placed in the material and holds the portion and steams, can satisfy the demand of different containers 310 through the structure of reasonable concave cavity that sets up, and then be favorable to enlarging the application range of product, specifically, the material holds 350 and can be for food steamer, steaming grid.

Specifically, as shown in fig. 3, the material containing part 350 is provided with at least one drain hole 3502, so that when the material to be cooked placed on the material containing part is cooked, the water condensed on the material containing part can drain the material containing part 350 from the drain hole 3502 under the action of gravity, thereby avoiding the problem that the material to be cooked is wetted due to more accumulated water formed on the material containing part, affecting the cooking effect of the material to be cooked or deforming the material to be cooked, and further ensuring good cooking effect and attractiveness of the material to be cooked.

Specifically, the material container 350 is not provided with the water discharge hole 3502, and the material container 350 may be used for steaming rice or the like.

Wherein arrows in fig. 1, 2, 7, 9 and 10 indicate the flow direction of the steam.

Specifically, the isolator 100 includes any one or combination of the following: metal isolators, plastic isolators, glass isolators, ceramic isolators, and wooden isolators.

Specifically, fig. 1, 2 and 7 indicate the position of the water line 360, when the household appliance 300 is operated, the water line 360 is located above the first chamber 110, the volume of the first chamber 110 is small, that is, when the separator 100 is placed in the container 310, the medium of the first chamber 110 inevitably flows into the second chamber 140 through the first medium channel 130, and the second chamber 140 is filled with the medium, so that the second chamber 140 plays a role of a counterweight to increase the weight of the separator 100, and the separator 100 is not jacked up by bubbles.

Specifically, the separator 100 further includes an insulation structure located outside the first chamber 110. For example, the insulation structure can be disposed on the insulation cartridge 1602 and/or the plate 1604, and further for example, the insulation structure can have a hollow chamber, or the insulation structure can have an insulation cavity with insulation material disposed therein. The heat insulation structure is arranged to enable the quantity of heat in the first cavity 110 to be smaller towards the outside of the isolator 100, and further enable most of heat generated by the heating element 340 to be absorbed by media in the first cavity 110 of the isolator 100, so that the time of the media from normal temperature to boiling and generating relatively stable steam can be greatly shortened by heating the media in the first cavity 110, and therefore the purpose of quickly generating high-temperature steam can be achieved, and the loss of heat is reduced.

In particular, the household appliances are an electric kettle, a steamer, a humidifier, a rice cooker, and the like, which are not listed here. The container is a kettle body, a water tank, a cooking pot and the like, which are not illustrated herein.

The specific embodiment is as follows:

the volume of the first chamber 110 is 80ml to 150ml, and if the volume of the first chamber 110 is too large, the heating is slow, the volume of the first chamber 110 is too small, the water is not supplemented in time, and the first chamber is easy to be dried.

The area of the dielectric layer is,for example, the area of the region surrounded by the outer edge of the liquid level restriction surface downward from the outer edge of the liquid level restriction surface satisfies 5000mm²To 35000mm². Specifically, the plate 1604 has a diameter of 150mm, and the area of the region surrounded by the outer edges of the liquid level restricting surfaces is 17660mm²If the area of the area surrounded by the outer edges of the liquid level limiting surface is too small, the heating area is small, and the heating is slow.

The height of the media layer, e.g., the spacing between the level limiting surface and a portion of the interior surface of the vessel 310, satisfies: 1mm to 20 mm. Specifically, the height of the dielectric layer satisfies 3mm to 7 mm. Specifically, the height of the dielectric layer was 3.5 mm. If the height of the medium layer is too small, bubbles generated by boiling fill the first chamber 110, resulting in no water being heated, and local temperature anomalies are easily generated.

The width of the exhaust passage, e.g., the interval between the partition 150 and the partition plate 160, satisfies 0.5mm to 10 mm. Specifically, the width of the exhaust passage satisfies 1mm to 3 mm; the area of the exhaust passage, i.e., the area of the slit 170 in any cross section of the partition plate 160, satisfies 200mm²To 2000mm². Specifically, the area of the slit 170 satisfies 400mm²To 700mm². Specifically, the width of the exhaust passage is 2mm, and the area of the slit 170 is 500mm². If the area is too small, the exhaust is not timely, and a larger pressure is easily generated to jack up the isolator 100; too large an area, too much water that cannot be effectively heated, results in the heat of the steam being absorbed and the steam generation being slow.

The ratio of the area of the exhaust passage to the area of the medium layer satisfies 0.015 to 0.05. Specifically, the following components: the ratio of the area of the exhaust passage to the area of the medium layer was 0.028.

The ratio of the average power of the heating period to the area of the dielectric layer satisfies 0.03W/mm²To 3.4W/mm². Specifically, the ratio of the average power of the heating period to the area of the dielectric layer satisfies 0.8W/mm²To 1.2W/mm²(ii) a The average power of the heating period satisfies the following conditions: 150W to 1800W. Specifically, the average power of the heating period is 500W to 1000W, wherein the area of the corresponding dielectric layer is 5000mm²。
