Example 1

As shown in fig. 6 to 10, the present embodiment provides a condensation steam discharge assembly for condensing high-temperature steam and discharging condensed water and low-temperature steam generated by condensation. The condensation steam exhaust component comprises a condensation steam exhaust cavity, and a steam inlet 41, a steam exhaust 42 and a water outlet 45 which are communicated with the condensation steam exhaust cavity;

high-temperature steam enters the condensation steam exhaust cavity from the steam inlet 41 and is condensed to generate low-temperature steam and condensed water, the low-temperature steam flows out of the condensation steam exhaust assembly from the steam exhaust port 42, and the condensed water flows out of the condensation steam exhaust assembly from the water outlet 45.

Because the temperature of the condensation steam exhaust assembly is generally lower than that of high-temperature steam entering the condensation steam exhaust cavity, the high-temperature steam is condensed in the condensation steam exhaust cavity to generate low-temperature steam and condensed water; the comdenstion water flows out from outlet 45, and low temperature steam flows out from steam exhaust port 42, if with the condensation steam extraction subassembly of this embodiment use with steam cooking equipment in, can condense from the exhaust high temperature of culinary art intracavity, has so not only reduced the temperature of the steam of discharge steam cooking equipment, but also reduced the water content, the effectual great problem of water content in the exhaust steam that has solved present steam cooking equipment existence.

In order to improve the condensation effect, the steam inlet 41 and the steam outlet 42 are respectively disposed on two opposite sides of the condensation steam exhaust cavity, so as to increase the distance between the steam inlet 41 and the steam outlet 42 as much as possible, and further increase the residence time of the high-temperature steam in the condensation steam exhaust cavity.

As shown in fig. 8, in order to completely discharge the condensed water in the condensed steam discharging cavity, a water outlet 45 is provided at a concave part at the bottom of the condensed steam discharging cavity; or the bottom of the condensation exhaust cavity is an inclined plane, and the lowest part of the inclined plane is provided with a water outlet 45. Preferably, the bottom of the first housing 43 is an inclined surface, and a drain port 45 is opened at the lowest part of the inclined surface.

Example 2

As shown in fig. 2, 3 and 21, the present embodiment provides a steam cooking device, which includes a cooking device body, and the condensation steam exhaust assembly 4 of embodiment 1, wherein the steam inlet 41 of the condensation steam exhaust assembly 4 is communicated with a cooking cavity of the cooking device body, and the steam outlet 42 of the condensation steam exhaust assembly 4 is communicated with the air duct 5 of the cooking device body.

High-temperature steam flowing out of the cooking cavity enters the condensation steam exhaust cavity through the steam inlet 41, and the high-temperature steam is condensed in the condensation steam exhaust cavity to generate condensed water and low-temperature steam because the temperature in the condensation steam exhaust cavity is lower than that of the high-temperature steam; the low-temperature steam flows out from the steam outlet 42 and enters the air duct 5, and is finally discharged out of the steam cooking equipment by the air duct 5, so that the problem that the water content in the discharged steam is large in the conventional steam cooking equipment is solved.

As shown in fig. 21, in this embodiment, a top cover 8 covers the top of the cooking apparatus body to form an accommodating cavity, a condensation steam exhaust assembly 4, a heat dissipation fan 3 and an air duct 5 are installed in the accommodating cavity, and a plurality of air inlet grilles 81 communicated with the accommodating cavity are further formed on the top cover 8; the heat radiation fan 3 is arranged at the air inlet of the air duct 5, and the steam outlet 42 of the condensation steam exhaust component 4 faces the negative pressure area of the heat radiation fan 3 and is used for exhausting low-temperature steam into the air duct 5.

The cooling fan 3 is started, cold air outside the steam cooking equipment enters a negative pressure area of the cooling fan 3 from the air inlet grille, and meanwhile, low-temperature steam condensed by the condensation steam exhaust assembly 4 also enters the negative pressure area of the cooling fan 3 to be mixed with the cold air, so that the low-temperature steam is condensed again to generate ultralow-temperature steam and condensed water; the ultralow-temperature steam is discharged into the air duct 5 by the heat dissipation fan 3 and finally discharged out of the steam cooking equipment through the air duct 5; and the condensed water drops on the heat dissipation fan 3 to cool the heat dissipation fan 3.

Specifically, the condensation steam exhaust assembly 4 is installed on the rack of the heat dissipation fan 3, and the steam exhaust port 42 is in a strip shape, and is used for ensuring that low-temperature steam can be uniformly blown to the heat dissipation fan 3.

In this example, the steam outlet 42 of the condensation steam exhaust assembly 4 communicates with the water collecting device of the cooking apparatus body. Wherein the water collecting means is a water box 6, a steam generator 2 or a waste water tank.

In the embodiment, the steam generator 2 is preferably selected as the water collecting device, so that the waste of water is avoided, the utilization time of single water in the water box 6 is prolonged to a certain extent, and the problem that the service time of once water adding of the water tank of the existing steam cooking equipment is short is solved.

As shown in fig. 1 to 5, in order to further improve the condensing effect, the steam cooking apparatus of the present embodiment further includes a condenser 1 for condensing high-temperature waste steam from the cooking cavity;

the heat radiation fan 3 is arranged at the air inlet of the air duct 5, and the steam outlet end of the condenser 1 is communicated with the condensation steam exhaust cavity of the condensation steam exhaust component 4; the steam outlet 42 of the condensation steam exhaust component 4 faces the negative pressure area of the heat radiation fan 3 and is used for discharging low-temperature waste steam which is condensed by the condenser 1 and the condensation steam exhaust cavity in sequence out of the steam cooking equipment through the air duct 5, and condensed water generated by condensation in the condensation steam exhaust cavity flows to the steam generator 2.

Because the steam inlet end of the condenser 1 is communicated with the cooking cavity, high-temperature steam in the cooking cavity enters the condenser 1 to exchange heat with the condenser 1 to generate low-temperature waste steam and condensed water.

Because the steam outlet end of the condenser 1 is communicated with the condensation steam exhaust cavity through the steam inlet 41 of the condensation steam exhaust component 4, the steam outlet 42 of the condensation steam exhaust component 4 faces the negative pressure area of the heat dissipation fan 3, and the heat dissipation fan 3 is arranged at the air inlet of the air duct 5 to be exhausted, after the low-temperature waste steam condensed by the condenser 1 enters the condensation steam exhaust cavity of the condensation steam exhaust component 4, because the temperatures of the condensation steam exhaust cavity and the condensation steam exhaust component 4 are usually lower than the temperature of the low-temperature waste steam, the low-temperature waste steam can be condensed again to generate second condensed water and lower-temperature waste steam when passing through the condensation steam exhaust cavity; the waste steam with lower temperature flows to the negative pressure area of the heat radiation fan 3 from the steam outlet 42 of the condensation steam exhaust component 4, is mixed with other low-temperature air in the negative pressure area and is condensed again to form ultralow-temperature waste steam and third condensate water, and the ultralow-temperature waste steam enters the air duct 5 and is finally discharged out of the steam cooking equipment. This reduces the amount of steam and the temperature of the steam discharged from the front of the cooking apparatus, and solves the problems of the steam cooking apparatus that the amount of the steam discharged from the front is large and the temperature is high. And the third condensate water is dripped on the cooling fan 3 to play a role in cooling the cooling fan 3. The second comdenstion water then flows into steam generator 2 in through the wet return, just so increased the utilization time of the single water in the water box to a certain extent, has solved the problem that present steam cooking equipment's water tank once adds water live time short.

In the embodiment, in order to further increase the utilization time of the single water in the water box 6, one water outlet channel of the water box 6 is communicated with the steam generator 2 through the condenser 1 for sequentially delivering cold water to the condenser 1 and the steam generator 2; the other path of water outlet channel of the water box 6 is communicated with the steam generator 2 and used for recovering residual water in the steam generator 2.

Because one path of water outlet channel of the water box 6 is communicated with the steam generator 2 through the condenser 1 and is used for sequentially conveying cold water to the condenser 1 and the steam generator 2, the water equivalent to the water box 6 flows into the steam generator 2 after passing through the condenser 1, and at the moment, if high-temperature steam exists in the condenser 1, the cold water and the high-temperature steam exchange heat to increase the condensation efficiency; in addition, water entering the evaporation chamber of the steam generator 2 generates high-temperature steam in the evaporation chamber after the steam generator 2 is started, and the high-temperature steam enters the cooking cavity to exchange heat with food.

Because the steam inlet end of the condenser 1 is communicated with the cooking cavity, high-temperature steam in the cooking cavity enters the condenser 1 to exchange heat with the condenser 1 and/or cold water in the condenser 1 so as to generate low-temperature steam and condensed water.

Because the steam outlet end of the condenser 1 is communicated with the condensation steam exhaust cavity of the condensation steam exhaust component 4, and the steam exhaust port 42 of the condensation steam exhaust component 4 is communicated with the air duct 5 through the heat radiation fan 3, when the low-temperature waste steam condensed by the condenser 1 passes through the condensation steam exhaust component 4, the low-temperature waste steam is condensed again in the condensation steam exhaust cavity to generate second condensed water and lower-temperature waste steam; lower temperature exhaust steam then enters into wind channel 5 under radiator fan 3's effect in, so low temperature exhaust steam can be further condensed in order to produce third condensate water and ultra-low temperature exhaust steam behind radiator fan 3, the exhaust steam cooking equipment behind the ultra-low temperature exhaust steam entering wind channel 5. This reduces the amount of steam and the temperature of the steam discharged from the front of the cooking apparatus, and solves the problems of the steam cooking apparatus that the amount of the steam discharged from the front is large and the temperature is high.

Because a part of the water in the steam generator 2 comes from the cold water flowing out of the water box 6 and through the condenser 1 into the steam generator 2; the other part comes from the condensed water flowing from the condenser 1 to the steam generator 2, so that the recycling of the water is realized; and the evaporation chamber of the steam generator 2 is also communicated with the water box 6 and used for returning the residual water of the steam generator 2 to the water box 6, so that the utilization time of the single water in the water box is prolonged, and the problem that the service time of the water tank of the conventional steam cooking equipment for adding water once is short is solved.

In the embodiment, the steam generator 2 is provided with a high-temperature steam outlet and a water return port 21 which are communicated with the evaporation chamber; the high-temperature steam outlet is communicated with the cooking cavity, and the water return port 21 is communicated with the water outlet end of the condenser 1 and the water inlet end of the water box 6. Preferably, the water return port 21 is provided at the bottom of the steam generator 2.

Because the return water port 21 is arranged at the bottom of the steam generator 2, water flowing out from the water outlet of the condenser 1 has a sealing effect on the return water port 21, and the steam generated by the steam generator 2 is prevented from flowing into the water box 6 through the return water port 21, so that the steam amount in the cooking cavity is reduced.

In this embodiment, the water outlet 45 of the condensing and steam-discharging component 4 is further communicated with the water return port 21, so that the second condensed water condensed in the condensing and steam-discharging cavity flows to the evaporation chamber of the steam generator 2, and the recycling rate of water is further improved.

As shown in fig. 1, in this example, the steam cooking apparatus further includes a pumping unit group 7, and the pumping unit group 7 is disposed on the water outlet passage of the water box 6 at least for pumping the residual water in the steam generator 2 back to the water box 6.

Preferably, the water pumping unit group 7 comprises a first water pumping unit 71 and a second water pumping unit 72; the first water pumping unit 71 is arranged on one path of water flow channel of the water box 6 communicated with the condenser 1 and used for pumping cold water in the water box 6 to the condenser 1; the second pumping unit 72 is disposed on the other water flow path of the water box 6 communicated with the steam generator 2 for pumping the residual water in the steam generator 2 back to the water box 6.

Preferably, the first water pumping unit 71 and the second water pumping unit 72 are both water pumping pumps;

preferably, the water box 6 and the condenser 1 are both disposed at the top of the steam cooking device, and the steam generator 2 is disposed below the rear sidewall of the steam cooking device, so that there is a height difference between the water box 6, the condenser 1 and the steam generator 2, and in order to allow water of the water box 6 to enter into the condenser 1, a suction pump is disposed on a water flow path between the water box 6 and the condenser 1, and cold water entering into the condenser 1 flows back to the steam generator 2 under the action of gravity.

A temperature sensor is arranged at the bottom of the evaporation chamber of the steam generator 2, when the temperature detected by the temperature sensor is not less than a temperature threshold value (namely a temperature value when the steam generator 2 is dry-burned), it indicates that water needs to be added to the steam generator 2, at this time, a first water pumping unit 71 (water pump) is started, cold water stored in a water box 6 is pumped into the condenser 1, and water entering the condenser 1 finally flows into the evaporation chamber of the steam generator 2 under the action of gravity; meanwhile, the water amount added into the steam generator 2 is calculated by controlling the water pumping time and the water pumping flow rate of the first water pumping unit 71, so that the water is prevented from overflowing the steam generator 2.

Since there is a height difference between the water tub 6 and the steam generator 2 is located above the water tub 6, in order to transfer the remaining water in the steam generator 2 back to the water tub 6, it is necessary to install a second pumping unit 72 on a water flow path between the water tub 6 and the steam generator 2.

Preferably, the water inlet end of the second water pumping unit 72 is communicated with the water return port 21 of the steam generator 2 through a water pipe, and the water outlet end of the second water pumping unit 72 is communicated with the water box 6 through a water pipe, so that after the second water pumping unit 72 is started, water in the evaporation chamber of the steam generator 2 returns to the water box 6 through the water return port 21 and the second water pumping unit 72, so as to ensure that bacteria cannot breed in the steam cooking device due to residual water, and the service time of adding water into the water box for one time is prolonged.

As shown in fig. 19 to 20, a plurality of heat dissipation fins 142 are arranged in parallel to each other at intervals on the heat dissipation plate 141 to form wide heat dissipation channels and narrow heat dissipation channels perpendicular to each other for the purpose of enhancing heat dissipation effect.

The working process of the embodiment is as follows:

as shown in fig. 1-5, if the temperature sensor in the evaporation chamber of the steam generator 2 detects that the temperature of the steam generator 2 is higher than the temperature threshold (i.e. dry-heating temperature), the first water pumping unit 71 (water pump) is started, and the water in the water box 6 is pumped into the condensation chamber of the condenser 1 through the water inlet channel 113, and then flows into the evaporation chamber through the water outlet channel 114 to the water return port 21 of the steam generator 2, so as to achieve the purpose of supplying water to the steam generator 2. In the process of pumping water, if high-temperature steam exists in the condensation chamber, the water entering the condensation chamber also has the condensation effect on the high-temperature steam, and the condensed water is mixed with the original water in the condensation chamber and then flows to the evaporation chamber from the water outlet flow channel 114. During the pumping process, the amount of water added to the steam generator 2 is calculated based on the time the first pumping unit 71 is operated and the water flow rate, so as to prevent the water from overflowing the steam generator 2.

After water is filled in the steam generator 2, the steam generator 2 is heated to generate steam, and the steam flows out from a high-temperature steam outlet of the steam generator 2 and directly enters the cooking cavity to exchange heat with food, so that the purpose of cooking the food is achieved; after the high-temperature steam in the cooking cavity flows out from the steam outlet of the cooking cavity, the high-temperature steam enters the condensation cavity through the steam inlet flow channel 111 of the condenser 1, and meanwhile, the cooling fan 131 of the cooling assembly 13 is started to cool the shell assembly 11 and the cooling assembly 14.

The high-temperature steam entering the condensation chamber flows along the wide steam channel and the narrow steam channel of the condensation assembly 12, and because the temperature of the condensation sheet 121 and the temperature of the condensation chamber are lower than that of the high-temperature steam, the high-temperature steam is condensed in the flowing process of the condensation chamber, and low-temperature steam and condensed water are generated.

After the low-temperature steam flows out from the steam outlet flow channel 112, the low-temperature steam enters the condensation steam discharging cavity through the steam inlet 41 of the condensation steam discharging component 4, because the temperature of the condensation steam discharging cavity is also low, the low-temperature steam is condensed again, then enters the air duct 5 through the steam outlet 42 and the negative pressure area of the heat dissipation fan 3, and finally flows out from the front air outlet of the steam cooking device.

The condensed water flows out from the water outlet flow channel 114 again, enters the water return port 21 at the bottom of the steam generator 2 through the water return pipe, seals the water return port 21, avoids that the steam generated by the steam generator directly enters the condenser 1 and the water box 6, reduces the starting times of the first water pumping unit 71 in unit time, and increases the service time of once water adding in the water tank.

After the second water pumping unit 72 (water pump) is started, the condensed water in the water return pipeline and the stored water in the steam generator 2 are pumped back to the water box 6, so that the residual water in the steam cooking device is reduced, and the service time of adding water into the water box for one time is prolonged.

The steam cooking equipment can be a steam box, a steam oven, a steam-baking all-in-one machine, a micro steam box, a micro steam oven and other cooking equipment.
