Description

Technical Field

[0001] The present invention belongs to the technical field of household electrical appliances, and more particularly, to a steam oven. Background Art

[0002] As a commonly used kitchen electrical appliance, steam ovens are becoming increasingly popular among people. However, existing steam ovens usually have some problems in terms of pressure relief. For example, when a high-power steam oven is operating, the pressure inside the cabinet is too high, and steam overflows, affecting the user experience and causing energy consumption waste. The steam at the pressure relief port only relies on natural cooling and condensation, resulting in a problem that the temperature of the sheet metal parts increases during the use of the steam oven, leading to a decrease in the condensation effect. In addition, some steam ovens directly discharge the steam into the oven air duct for cooling and condensation, resulting in a large attachment area of the condensed water in the air duct, making it difficult to collect. The uncollectible condensed water will corrode the sheet metal parts.

[0003] Therefore, how to solve the problem of steam overflow during pressure relief of the steam oven and how to collect and utilize the condensed water are urgent problems to be solved at present. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a steam oven. A condensation part is arranged in the water tank, so that the steam in the oven cavity of the steam oven is discharged through a steam pressure relief pipe and flows into the condensation part from the steam pressure relief pipe. The condensation part cooperates with the water tank to condense the steam.

[0005] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A steam oven, comprising:

[0007] A water tank for storing water;

[0008] A pressure relief pipe for discharging the steam in the oven cavity of the steam oven;

[0009] A condensation part is arranged on the pressure relief pipe, and the condensation part cooperates with the water tank to condense the steam flowing through the condensation part or the pressure relief pipe.

[0010] Further, the condensation part is arranged in the water tank.

[0011] Further, the condensation part extends obliquely upward along the direction of air flow.

[0012] Further, it further comprises a gas-liquid separation box for separating the steam discharged from the pressure relief pipe into condensed water.

[0013] The gas-liquid separation box is communicated with the water tank through a water pipe, and the condensed water separated by the gas-liquid separation box flows into the water tank through the water pipe.

[0014] Further, the pressure relief pipe further includes an exhaust section disposed outside the water tank and communicating with the condensation section.

[0015] The steam in the oven cavity flows from the pressure relief pipe to the condensation section, and part of the steam in the condensation section flows to the exhaust section and is discharged from the exhaust section.

[0016] Further, the condensation section is a pipe communicating with the pressure relief pipe, and the condensation section includes a first section and a second section that communicate with each other.

[0017] The slopes of the first section and the second section are different.

[0018] Further, a first connection port connected to the first section of the condensation section and a second connection port connected to the second section are provided on the wall of the water tank body.

[0019] The first connection port and the second connection port are provided on the same side of the water tank or respectively provided on different side walls.

[0020] Further, the condensation section and the pressure relief pipe are integrally formed.

[0021] Further, the pressure relief pipe further includes a pressure relief section disposed outside the water tank and communicating with the oven cavity.

[0022] The pressure relief section communicates with the first section of the condensation section, and the steam in the oven cavity flows from the pressure relief section to the condensation section.

[0023] Further, one end of the pressure relief section of the pressure relief pipe communicates with the oven cavity, and the other end relative to the oven cavity communicates with the first connection port.

[0024] One end of the exhaust section of the pressure relief pipe communicates with the gas-liquid separation tank, and the other end relative to the gas-liquid separation tank communicates with the second connection port.

[0025] After adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art:

[0026] 1. A condensation section is provided in the water tank, so that the steam in the oven cavity is discharged through the steam pressure relief pipe and flows into the condensation section from the steam pressure relief pipe. The condensation section cooperates with the water tank to condense the steam, and the condensed water flows back to the oven cavity. The steam in the oven cavity is discharged through the pressure relief pipe, avoiding steam overflow. At the same time, it cooperates with the water tank to condense the steam and recover the condensed water, reducing the air pressure in the oven cavity.

[0027] 2. The remaining uncondensed steam flows from the condensation part to the exhaust section of the steam relief pipe, is discharged from the exhaust section into the gas-liquid separation tank, and is further condensed by the gas-liquid separation tank. The condensed water flows into the water tank. Since the water in the steam generator comes from the water tank, the water in the water tank is preheated through the recovery of the condensed water. While recycling the condensed water, it is beneficial to protect the steam generator.

[0036] As a commonly used kitchen electrical appliance, steam ovens are also increasingly favored by people. However, existing steam ovens usually have some problems in pressure relief. For example, when a high-power steam oven is operating, the pressure in the cabinet is too high and steam overflows, affecting the user experience and causing energy consumption waste. The steam at the pressure relief port only relies on natural cooling and condensation, resulting in a problem that the temperature of the sheet metal parts will rise during the use of the steam oven, leading to a decrease in the condensation effect. In addition, some steam ovens directly discharge the steam into the oven air duct for cooling and condensation, resulting in a large attachment area of the condensed water in the air duct, making it difficult to collect, and the uncollected condensed water will corrode the sheet metal parts.

[0037] Therefore, the present invention provides a steam oven. A condensation part is arranged in the water tank, so that the steam in the oven cavity is discharged through a steam pressure relief pipe and flows into the condensation part from the steam pressure relief pipe, and the condensation part cooperates with the water tank to condense the steam.

[0038] The following refers to Figure 1 Describe some embodiments of the steam oven of the present invention.

[0039] As Figure 1 shown, a steam oven includes an oven cavity 10 for cooking food; a steam generator 1 for generating steam and delivering the steam into the oven cavity 10. The oven cavity 10 is connected to the steam generator 1 through a steam pipe 12. It further includes a water tank 2 for storing water to be delivered to the steam generator 1, and the water tank 2 is connected to the steam generator 1 through a water inlet pipe 11. A pressure relief pipe 3 is used to discharge the steam in the oven cavity 10. A condensation part 5 is communicated with the pressure relief pipe 3. It further includes a gas-liquid separation tank 4, and the gas-liquid separation tank 4 is connected to the oven cavity 10 through the pressure relief pipe 3.

[0040] The oven cavity 10 includes a pressure relief port. One end of the pressure relief pipe 3 is connected to the pressure relief port of the oven cavity 10, and the other end is connected to the gas-liquid separation tank 4. The pressure relief pipe 3 is used to discharge the steam in the oven cavity 10.

[0041] A steam oven in this embodiment further includes a condensation part 5 communicated with the pressure relief pipe 3. The condensation part 5 cooperates with the water tank 2 to condense the steam flowing through the condensation part 5. Exemplarily, the condensation part 5 cooperates with the water tank 2 to condense the steam flowing through the condensation part 5 through the water in the water tank 2.

[0042] In some preferred embodiments of the present embodiment, the condensation part 5 is arranged in the water tank.

[0043] In this embodiment, the flow direction of the steam is the air flow direction. Exemplarily, Figure 1 The arrows shown in indicate the flow process of the steam from the steam generator 1 to the gas-liquid separation tank 4, where a, b, c, d, f are the flow paths. b, c, d, e are the processes where the steam flows into the condensation part 5, condenses into water in the condensation part 5, and then returns to the oven cavity 10. The arrow n indicates the water flow process where the condensed water in the gas-liquid separation tank 4 returns to the water tank 2 after the steam flows into the gas-liquid separation tank 4. The arrow m indicates the water flow direction of the water in the water tank flowing into the steam generator 1.

[0044] The water tank 2 is arranged above the oven cavity 10, and the condensation part 5 extends upward obliquely in the water tank 2 along the air flow direction of the steam. Exemplarily, the extending section extending upward obliquely forms an angle with the wall of the water tank 2. Exemplarily, the connection part where the condensation part 5 communicates with the pressure relief pipe 3 is on the side wall of the water tank 2. The condensation part 5 starts to extend from the connection part communicating with the pressure relief pipe 3 into the water tank 2, and the extending section extending obliquely along the air flow direction in the water tank 2 forms an angle with the bottom wall of the water tank 2, which is beneficial to the upward flow of the steam and also beneficial to the condensed water condensed in the condensation part 5 to return to the oven cavity 10.

[0045] The condensation part 5 includes a first section 51 and a second section 52 that are connected to each other. The slope of the first section 51 is less than the slope of the second section 52. And the horizontal position of the first section 51 is lower than the horizontal position of the second section 52. The condensation effect of the first section 51 is greater than that of the second section 52.

[0046] On the wall of the water tank 2, there is a first connection port 21 connected to the first section 51 of the condensation part 5 and a second connection port 22 connected to the second section 52 of the condensation part 5. The first connection port 21 and the second connection port 22 are arranged on the same side wall or different side walls of the water tank 2.

[0047] Taking the example that the first connection port 21 and the second connection port 22 are arranged on the same side wall of the water tank, and further taking the example of being arranged on the right side wall or the left side wall of the box body wall of the water tank 2, the installation position of the first connection port 21 is lower than the installation position of the second connection port 22. The first section 51 of the condensation part 5 extends from the first connection port 21 into the interior of the water tank 2. There is a bent section that bends and extends between the first section 51 and the second section 52, and the bent section is also the connection part between the first section 51 and the second section 52. The air flow direction of the second section 52 of the condensation part 5 is different from that of the first section 51. One end of the first section 51 is connected to the first connection port 21, and the other end is connected to the second section 52. The end of the second section 52 relative to the first section 51 is connected to the second connection port 22. In the above setting method, when there is one bent section, the slope of the first section 51 is smaller than that of the second section 52.

[0048] In some solutions of this embodiment, the first section 51 and the second section 52 can be bent multiple times to form multiple bent sections, that is, the condensation part 5 has a wavy structure. This is beneficial to increasing the condensation time and improving the condensation efficiency.

[0049] Exemplarily, taking the example that the first connection port 21 and the second connection port 22 are arranged on different side walls of the water tank, the first connection port 21 can be arranged on the left side wall of the water tank 2, and the second connection port 22 can be arranged on the right side wall of the water tank. In the horizontal direction, the installation position of the first connection port 21 is lower than that of the second connection port 22. While extending within the maximum range in the water tank 2 to increase the contact area and contact time between the condensation part 5 and the water in the water tank 2, it is beneficial for the steam to flow upward and flow out.

[0050] In some preferred implementation manners of this embodiment, the condensation part 5 and the pressure relief pipe 3 are integrally formed. That is, the condensation part 5 is a part of the pressure relief pipe 3, and a part of the pressure relief pipe 3 is arranged inside the water tank 2 to form the condensation part 5.

[0051] The steam in the pressure relief pipe 3 flows into the condensation part 5, and the steam in the condensation part 5 condenses into water and flows back to the oven cavity 10, reducing the air pressure in the oven cavity 10.

[0052] The gas-liquid separation box 4 of a steam oven described in this embodiment is used to separate the steam discharged from the pressure relief pipe 3 into condensed water and gas. The gas flows out to the outside through the gas pipe 42. The gas-liquid separation box 4 is communicated with the water tank 2 through the water pipe 41, and the condensed water separated by the gas-liquid separation box 4 flows into the water tank 2 through the water pipe 41. This is beneficial to preheating the water in the water tank 2 and improving the working efficiency of the steam generator 1.

[0053] The pressure relief pipe 3 further includes an exhaust section 31 disposed outside the water tank 2 and communicating with the condensation section 5. The steam in the oven cavity 10 flows from the pressure relief pipe 3 to the condensation section 5. Part of the steam in the condensation section 5 flows to the exhaust section 31 and is discharged from the exhaust section 31. Exemplarily, the steam flowing into the condensation section 5 from the pressure relief pipe 3 is condensed into water under the cooperation of the condensation section 5 and the water tank 2 and flows back to the oven cavity 10. However, part of the uncondensed steam in the condensation section 5 flows to the exhaust pipe 31 and is discharged from the exhaust pipe 31 into the gas-liquid separation tank 4, avoiding scalding the user caused by direct discharge to the outside. The gas-liquid separation tank 4 further condenses the steam discharged from the exhaust pipe 31, and the condensed water flows back into the water tank 2 to replenish the water tank 2, and part of the steam is discharged to the outside. The exhaust section 31 is communicatively connected to the gas-liquid separation tank 4.

[0054] The pressure relief pipe 3 in this embodiment further includes a pressure relief section 32 disposed outside the water tank 2 and communicating with the oven cavity 10. The pressure relief section 32 is interconnected with the first section 51 of the condensation section 5. The steam in the oven cavity 10 flows from the pressure relief section 32 of the pressure relief pipe 3 to the condensation section 5. This is beneficial for first relieving and discharging the steam in the oven cavity 10 and then condensing it, avoiding excessive condensed water accumulation entering the oven cavity 10 and affecting the working efficiency of the steam oven.

[0055] One end of the pressure relief section 32 of the pressure relief pipe 3 communicates with the oven cavity 10, and the end opposite to the oven cavity 10 communicates with the first connection port 21;

[0056] One end of the exhaust section 31 of the pressure relief pipe 3 communicates with the gas-liquid separation tank 4, and the end opposite to the gas-liquid separation tank 4 communicates with the second connection port 22.

[0057] In the steam generator 1 provided in this embodiment, the steam generator 1 is communicatively connected to the water tank 2 through a water inlet pipe 11, and the water in the water tank 2 flows into the steam generator 1 through the water inlet pipe 11. The steam generator 1 is communicatively connected to the oven cavity 10 through a steam pipe 12, and steam is delivered into the oven cavity 10 through the steam pipe 12.

[0058] In this embodiment, the condensation section 5 is disposed in the pressure relief pipe 3, and the condensation section 5 cooperates with the water tank 2 to condense the steam flowing through the condensation section 5 or the pressure relief pipe 3. Specifically, when the condensation section 5 is a pipe communicating with the pressure relief pipe 3, the condensation section 5 cooperates with the water tank 2 to condense the steam flowing through the condensation section 5.

[0059] When the condensation section 5 is a cooling component such as a heat sink disposed on the pressure relief pipe 3, the condensation section 5 cooperates with the water tank 2 to condense the steam flowing through the pressure relief pipe 3.

[0060] When the condensation section 5 is a pipe communicating with the pressure relief pipe 3, the condensation section 5 can be a part of the pressure relief pipe 3, and the condensation section 5 is disposed in the water tank 2.

[0061] In this embodiment, another implementation manner is provided in which a condensation part 5 is arranged on the pressure relief pipe 3 to cool the pressure relief pipe 3. The condensation part 5 can be a heat sink with a cooling effect, etc. The condensation part 5 contacts water to cool the pressure relief pipe 3, and at the same time condenses the steam in the pressure relief pipe 3 into water and returns it to the oven cavity 10. Exemplarily, a part of the pressure relief pipe 3 is located inside the water tank 2. The condensation part 5 is arranged on the part of the pressure relief pipe 3 located inside the water tank 2.

[0062] In this embodiment, the cooperation mode between the condensation part 5 and the water tank 2 further includes that the condensation part 5 is a pipeline wound around the outer wall of the water tank. It can also be a pipeline that is connected to the pressure relief pipe 3 and wound around the outer wall of the water tank 2.

[0063] In some implementation manners of this embodiment, the condensation part 5 is connected to the pressure relief pipe 3, and the condensation part 5 cooperates with the water tank 2 to condense the steam flowing through the condensation part 5. The condensation part 5 is arranged inside the water tank 2.

[0064] The gas-liquid separation box 4 is connected to the pressure relief pipe 3 and is used to separate the steam discharged from the pressure relief pipe 3 into condensed water, and the remaining uncondensed steam is discharged from the gas-liquid separation box 4. In this setting mode, the oven cavity 10 is directly connected to the pressure relief pipe 3 for pressure relief. The gas-liquid separation box 4 and the water tank 2 are connected by a water pipe, and the water condensed in the gas-liquid separation box 4 flows back into the water tank 2. The condensation part 5 connected to the pressure relief pipe 3 is arranged inside the water tank 2 to condense the steam flowing through the condensation part 5, and the condensed water flows back into the oven cavity 10, which also plays a role in recycling and utilizing the condensed water.

[0065] In a further preferred manner, the pressure relief pipe 3 includes an exhaust section 31 arranged outside the water tank 2 and connected to the condensation part 5, and the gas-liquid separation box 4 is connected to the exhaust section 31. In this connection mode, the oven cavity 10 is indirectly connected to the gas-liquid separation box 4, reducing costs.

[0066] According to the exemplary embodiments of this specification, there is one or more of the following effects.

[0067] First, by arranging the condensation part in the water tank, the steam in the oven cavity is discharged through the steam pressure relief pipe and flows into the condensation part from the steam pressure relief pipe. The condensation part cooperates with the water tank to condense the steam, and the condensed water flows back into the oven cavity. The steam in the oven cavity is discharged through the pressure relief pipe, avoiding steam overflow. At the same time, it cooperates with the water tank to condense the steam and recover the condensed water, reducing the air pressure in the oven cavity.

[0068] Second, the remaining uncondensed steam flows from the condensation part to the exhaust section of the steam pressure relief pipe and is discharged from the exhaust section to the gas-liquid separation box, where it is further condensed by the gas-liquid separation box, and the condensed water flows into the water tank. Since the water in the steam generator comes from the water tank, preheating the water in the water tank by recycling the condensed water is beneficial to protecting the steam generator while recycling and utilizing the condensed water.

[0069] In a steam oven, when the air pressure in the cavity increases, steam needs to be discharged to relieve the pressure. The steam oven includes a pressure relief valve: when the pressure in the cavity exceeds the set safety value, the mechanically or electronically controlled pressure relief valve will automatically open and directly discharge the excess steam into the external environment.

[0070] During the pressure relief process, the steam first passes through a gas-liquid separator to separate the moisture in the steam, reducing moisture leakage. In this embodiment, the steam first condenses in the condensation part in cooperation with the water tank, and then the uncondensed steam flows into the gas-liquid separation box. The heat exchange between the contacting steam and the water tank preheats the water in the water tank and can also recycle the condensed water to reduce the air pressure in the oven cavity.

[0071] Some of the steam will be guided to a condensation circuit during the pressure relief process. Through heat exchange with a cooling medium, such as cold water in the water tank, the steam condenses into water. The condensed water is collected in the water tank used to generate steam, and the thermal energy is recovered to preheat the water entering the steam generator, improving the working efficiency of the steam generator.

[0072] The effects of the present disclosure may not be limited to the above and other purposes. Those skilled in the art of the embodiments can clearly understand other purposes not yet described through the claims.

[0073] This embodiment of the steam oven can be provided with a pressure relief program. In the pressure relief program, a multi-stage pressure relief method is designed, and a pressure sensor continuously monitors the air pressure in the oven cavity. When the pressure exceeds the first threshold, the first pressure relief program is started. The pressure sensor continuously monitors the pressure in the cavity to ensure that the pressure relief program is started before reaching the safety threshold. Multiple pressure thresholds are set to perform pressure relief step by step, avoiding sudden pressure release that may cause equipment damage.

[0074] In some aspects of this embodiment, the provided steam oven includes one or more of the following components: a processing component, a memory, a power component, a sensor component, a communication component, and a processor.

[0075] The memory is configured to store various types of data to support the operation of the steam oven.

[0076] The power component supplies power to various components of the steam oven. The power component may include a power management system, one or more power supplies, and other components associated with generating, managing, and distributing power for the steam oven.

[0077] The sensor component includes one or more sensors for providing a status assessment of various aspects of the steam oven. In some embodiments, the sensor component may further include a pressure sensor. For example, it can monitor the air pressure inside the steam oven.

[0078] The communication component is configured to facilitate communication between the steam oven and other devices in a wired or wireless manner. The steam oven can access a wireless network based on communication standards, such as WiFi, 2G, or 3G, or a combination thereof.

[0079] In an exemplary embodiment, the steam oven can be implemented by one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic components for performing the control method of the steam oven described above.

[0080] In an exemplary embodiment, a non-transitory computer-readable storage medium including instructions is also provided, such as a memory including instructions, and the above instructions can be executed by a processor of the steam oven to complete the control method of the steam oven. For example, the non-transitory computer-readable storage medium can be a ROM, random access memory (RAM), CD-ROM, magnetic tape, floppy disk, and optical data storage device, etc.

[0081] In another exemplary embodiment, a computer program product is also provided, which includes a computer program executable by a programmable device, and the computer program has a code portion for performing the control method of the steam oven described above when executed by the programmable device.

[0082] The above description is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications using the technical content prompted above into equivalent embodiments with equivalent changes.
