Description

Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to a steam generator and an oven. Background Art

[0002] A steam generator is a device that uses energy to heat water and turn it into steam. Steam generators are used in a variety of household appliances, such as steam ovens, hanging irons, steam mops, and steam cleaners.

[0003] Existing steam ovens usually include an oven body and a steam generator. In the steam oven, water is heated to generate steam. Through the appropriate temperature and humidity control, the moisture and nutrition inside the food are locked, making it more tender and delicious. The high-temperature baking function can form a golden and crispy crust on the surface of the food, keeping the original flavor of the food and preventing the loss of nutrition. The steam generator used in the existing steam oven usually includes a shell and an electric heating tube. The electric heating tube is arranged in the shell. Water enters the boiler from one side of the shell, is heated by the electric heating tube in the shell, and becomes steam and flows out from the other side of the boiler.

[0004] In this type of steam generator, water enters the shell and is heated by the electric heating tubes. The water accumulated in the shell will be sprayed out as the pressure in the boiler increases, so that liquid water is mixed in the water vapor flowing out of the steam generator, affecting the use effect of the steam generator. Moreover, there is only one evaporation process, and the water utilization rate is not high, so the oven needs to be matched with a larger water tank to meet the needs of steaming and baking, which will also make the oven too large, affecting the user experience.

[0005] Therefore, it is necessary to improve the existing steam generator to overcome the defects of the prior art. Utility Model Content

DETAILED DESCRIPTION

[0052] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0053] Example 1

[0054] like Figure 1-Figure 9 As shown, this embodiment provides a steam generator, which includes a first shell 100 and a second shell 200 that are arranged opposite to each other, and an evaporation chamber is formed between the first shell 100 and the second shell 200.

[0055] A partition 300 is arranged in the evaporation chamber, a first heating tube 400 is arranged above the partition 300, a second heating tube 500 is arranged below the partition 300, and a plurality of water leakage holes 310 are arranged on the partition 300, and a plurality of the water leakage holes 310 are arranged opposite to the second heating tube 500.

[0056] The first shell 100 is provided with a water inlet 110 , and the water inlet 110 is located above the partition 300 , so that water can flow through the water leakage hole 310 and fall on the second heating tube 500 .

[0057] Water enters the steam generator from the water inlet 110, and flows on the partition 300 due to the blocking effect of the partition 300. The first heating tube 400 heats the water on the partition 300. The water on the partition 300 flows to the water leakage hole 310 and drips onto the second heating tube 500. The second heating tube 500 heats the water into water vapor, and the water vapor flows out from the steam outlet 120, thereby achieving the output of heating the water into water vapor.

[0058] The first heating tube 400 and the second heating tube 500 are separated by the partition 300, so that water is first heated by the first heating tube 400 on the partition 300, and then drips onto the second heating tube 500 and is quickly heated to become water vapor. This can effectively prevent water from accumulating in the steam generator, better reduce the liquid water contained in the output water vapor, and improve the quality of the output water vapor.

[0059] Specifically, the power of the first heating tube 400 is greater than the power of the second heating tube 500 .

[0060] More specifically, the water inlet 110 and the steam outlet 120 are both disposed on the higher first shell 100 , which can effectively prevent the water inlet 110 from being blocked and also prevent the liquid water in the steam generator from flowing out of the steam outlet 120 due to pressure.

[0061] More specifically, the materials of the first shell 100 and the second shell 200 can be a combination of one or more of carbon steel, copper, aluminum, cast iron, nickel alloy and titanium alloy.

[0062] In this embodiment, the middle portion of the partition 300 bulges upward to form a water dividing peak 320, the length direction of the water dividing peak 320 is the same as the length direction of the partition 300, and along the width direction of the partition 300, water collecting grooves 330 are provided on both sides of the water dividing peak 320;

[0063] The height of the water collecting trough 330 is lower than the height of the top of the water dividing peak 320 , and the water leakage hole 310 is disposed in the water collecting trough 330 .

[0064] The water flow is guided by the partition 300 having the water dividing peak 320 and the water collecting groove 330, so that the water flow is evenly distributed on the partition 300 and finally flows to the water leakage hole 310, thereby avoiding local water accumulation and ensuring that the water can fully contact the second heating tube 500, thereby improving the vaporization efficiency.

[0065] In this embodiment, a steam outlet 120 is further provided on the first shell 100 . The steam outlet 120 is arranged opposite to the water inlet 110 . Along the direction from the water inlet 110 to the steam outlet 120 , the diameter of the water leakage hole 310 gradually increases.

[0066] Near the water inlet 110, the water temperature is low, and a smaller water leakage hole 310 is needed to control the water flow rate to prevent the water from flowing too quickly onto the second heating tube 500 and not being fully vaporized. As the water is gradually heated, the water temperature rises, and the vaporization speed increases, and a larger water leakage hole 310 is needed to ensure that the water can be vaporized in time and improve the vaporization efficiency.

[0067] In this embodiment, the minimum distance between the axis of the water leakage hole 310 close to the water inlet 110 and the inner end of the water inlet 110 is between 10 mm and 40 mm.

[0068] Specifically, the inner end of the water inlet 110 refers to an end of the water inlet 110 located on the inner side of the first shell 100 , that is, an end where water in the water inlet 110 drops to the partition 300 .

[0069] Since the temperature of the heating tube near the water inlet 110 is relatively low, the first water leakage hole 310 near the water inlet 110 is set between 10 mm and 40 mm away from the surface where the water inlet 110 is located. This can effectively ensure that when water drips from the water leakage hole 310 to the second heating tube 500, it can be quickly heated and evaporated, avoiding accumulation at the second heating tube 500.

[0070] In this embodiment, a water retaining plate 340 is provided at one end of the partition 300 away from the water inlet 110 , and the water inlet 110 protrudes upward from the edge of the partition 300 .

[0071] The water baffle 340 protrudes upward at the edge of the partition 300 to separate the evaporation chamber. The water flows into the chamber where the second heating tube 500 is located through the water leakage hole 310, ensuring that the water flows through two heating processes.

[0072] In this embodiment, the partition plate 300 is disposed between the first heating tube 400 and the second heating tube 500;

[0073] The length of the partition 300 is less than the length of the second shell 200 and greater than half the length of the second shell 200;

[0074] The first heating tube 400 is a straight tube type heating tube. Two first heating tubes 400 are provided. Both of the two first heating tubes 400 are arranged along the length direction of the first shell 100.

[0075] The second heating pipe 500 includes two straight pipe sections and a U-shaped bending section. The two straight pipe sections are arranged along the length direction of the second shell 200, and one end of the two straight pipe sections is exposed outside the second shell 200, and the other opposite end is located inside the second shell 200.

[0076] The U-shaped bending section is connected to the ends of the two straight pipe sections, and the U-shaped bending section is located in the second shell 200 .

[0077] The clamping method can effectively fix the partition 300, so that it remains stable during the operation of the steam generator, avoids shaking or displacement, and ensures its normal function. The length of the partition 300 is greater than half the length of the second shell 200, which can ensure that water flows from the water inlet 110 to the steam outlet 120, avoids water short circuit, and improves the vaporization efficiency.

[0078] Specifically, the partition 300 is tilted upward from the water collecting trough 330 to the edge of the partition 300, and elevated frames extend downward from both ends of the water collecting trough 330. The partition 300 is clamped between the first heating tube 400 and the second heating tube 500 through the tilting and the elevated frames, and the elevated frames create a certain distance between the water collecting trough 330 and the second heating tube 500.

[0079] Specifically, the ratio of the length of the partition 300 to the length of the shell can be adjusted according to actual application requirements to achieve optimal heat transfer efficiency and space utilization.

[0080] More specifically, the length of the partition plate 300 is the same as the length of the straight section of the second heating tube 500 in the second housing 200 .

[0081] The two straight heating tubes are arranged in parallel, which increases the heating area of ​​the water and improves the efficiency of the initial heating. The curved end of the U-shaped heating tube is close to the steam outlet 120, so that the water vapor can flow out more quickly, avoiding the accumulation of steam around the heating tube and improving the efficiency of steam generation.

[0082] In this embodiment, a temperature probe 600 is further included. A mounting column 210 is provided in the second shell 200. The mounting column 210 is located in the evaporation chamber. A mounting position is provided on the mounting column 210. The mounting position is located outside the mounting column 210. The temperature probe 600 is arranged in the mounting position.

[0083] The mounting column 210 is arranged on the inner side of the bottom of the second shell 200, and is used to fix the temperature probe 600 and prevent it from directly contacting the heating tube. The mounting position is drilled into the mounting column 210 from the outer side of the bottom of the second shell 200, and is used to accommodate the temperature probe 600 to prevent it from being directly impacted by the water flow. The temperature probe 600 is used to monitor the temperature inside the steam generator in real time and provide data support for the control system.

[0084] The mounting column 210 can transmit the temperature in the steam generator to the temperature probe 600 and can make the temperature acquired by the temperature probe 600 closer to the temperature of the steam.

[0085] In this embodiment, a sealing ring 700 is further included, and the sealing ring 700 is arranged at the joint between the first shell 100 and the second shell 200;

[0086] The sides of the first shell 100 and the second shell 200 are both provided with a joining block, and the first shell 100 and the second shell 200 are connected by the joining block;

[0087] The first housing 100 is further provided with a connection block 130 , and the connection block 130 is used for fixed connection with other devices.

[0088] The sealing ring 700 provided at the joint of the first shell 100 and the second shell 200 effectively prevents steam leakage, improves the safety of the equipment, and reduces energy loss. The design of the joint block makes the connection between the two shells more secure, ensures that the equipment will not loosen or fall off during operation, and enables the first shell 100, the second shell 200 and the sealing ring 700 to be pressure-fitted, thereby improving the sealing performance. The design of the connection block 130 facilitates the connection between the steam generator and other equipment, and improves the stability of the steam generator and other equipment.

[0089] Example 2

[0090] like Figure 1-Figure 9As shown, this embodiment provides a steam generator, which includes a first shell 100 and a second shell 200 that are arranged opposite to each other, and an evaporation chamber is formed between the first shell 100 and the second shell 200.

[0091] A partition 300 is arranged in the evaporation chamber, a first heating tube 400 is arranged above the partition 300, a second heating tube 500 is arranged below the partition 300, and a plurality of water leakage holes 310 are arranged on the partition 300, and a plurality of the water leakage holes 310 are arranged opposite to the second heating tube 500.

[0092] The first shell 100 is provided with a water inlet 110 , and the water inlet 110 is located above the partition 300 , so that water can flow through the water leakage hole 310 and fall on the second heating tube 500 .

[0093] In this embodiment, the middle portion of the partition 300 bulges upward to form a water dividing peak 320, the length direction of the water dividing peak 320 is the same as the length direction of the partition 300, and along the width direction of the partition 300, water collecting grooves 330 are provided on both sides of the water dividing peak 320;

[0094] Specifically, the partition 300 further includes a drainage channel, one end of which is disposed directly below the water inlet 110 , and the other end of which radiates to the water leakage hole 310 .

[0095] More specifically, the drainage channel may be a raised ridge line extending from below the water inlet 110 to the water leakage hole 310 , with grooves formed between the ridge lines to guide the water flow.

[0096] In this embodiment, the liquid water flowing in from the water inlet 110 is drained through the drainage channel, and the water is evenly guided from the water inlet 110 to each water leakage hole 310 to achieve more effective heating and water vapor generation. The raised drainage channel increases the surface area of ​​the partition 300, which can improve the heat conduction efficiency, and the water flow will contact more hot surfaces. The raised drainage channel can provide additional structural strength, especially in steam generators that withstand higher working pressures.

[0097] Example 3

[0098] like Figure 1-Figure 9 As shown, this embodiment provides an oven, which includes the above-mentioned steam generator.

[0099] In the process of generating steam in the oven by the steam generator, it is possible to effectively avoid the spraying of liquid water, thereby preventing the liquid water from affecting the food in the oven.

[0100] In this embodiment, the inner box 800 of the oven is provided with a condensate collecting tank 810, and the condensate collecting tank 810 is arranged on the bottom surface of the inner box 800. The steam generator is arranged on the side of the bottom of the inner box 800 away from the condensate collecting tank 810, and the top surface of the first shell 100 is connected to the bottom of the condensate collecting tank 810.

[0101] Specifically, the condensed water collecting tank 810 is disposed at the center of the bottom surface of the inner box body 800 .

[0102] More specifically, the oven also includes a water tank and a water pump. The water tank is connected to the water pump input end through a pipe, the water pump output end is connected to the water inlet 110 of the steam generator, and the steam outlet 120 is connected to the steam inlet of the inner box body 800 through a pipe. The steam inlet of the inner box body 800 is arranged at the lower part of the side of the inner box body 800, and the upper part of the side of the inner box body 800 is provided with an exhaust hole, and the exhaust hole is connected to the exhaust pipe to the outside of the oven.

[0103] More specifically, a guide ramp is provided at the bottom of the inner box 800 , and the guide ramp allows the condensed water at the bottom of the inner box 800 to flow to the condensed water collecting tank 810 .

[0104] More specifically, the condensate collecting tank 810 and the inner box body 800 may be integrated, or may be two separate components made of different materials or the same material.

[0105] During operation, the water pump pumps the water in the water tank into the steam generator, which is initially heated by the first heating tube 400 and secondarily heated by the second heating tube 500, evaporates to form water vapor, and is discharged into the inner box 800. It diffuses upward at the inlet, heats the objects in the inner box 800 or comes into contact with colder objects, and condenses into liquid water. The first shell 100 of the steam generator is connected to the condensate collecting tank 810. The first heating tube 400 in the first shell 100 heats the liquid water in the condensate collecting tank 810, and the liquid water evaporates into water vapor again, thereby increasing the water vapor content in the inner box 800.

[0106] In this embodiment, by reheating and evaporating the condensed water in the inner box 800, the condensed water in the box can be effectively utilized, and the water vapor content in the box can be increased, thereby improving the utilization rate of water, thereby reducing the amount of water required for steam cooking in the oven, and further reducing the volume of the water tank and the volume of the oven, making the oven more compact and improving the space utilization rate in the oven.

[0107] Example 4

[0108] like Figure 1-Figure 9 As shown, this embodiment provides a method for controlling an oven, and the method for controlling an oven is applied to the above-mentioned oven, comprising:

[0109] Get the cooking mode selected by the user;

[0110] Determining a heating mode of the oven and a steam intensity of the steam generator according to the selected cooking mode;

[0111] According to the determined heating mode and steam intensity, the number of heating tubes to be turned on is determined, and then cooking is performed.

[0112] By obtaining the cooking mode selected by the user, determining the steam intensity of the steam generator, determining the number of heating tubes that are turned on, and improving the degree of matching with the food to be cooked, the cooking effect can be effectively improved.

[0113] Specifically, the user can select the desired cooking mode, such as steaming mode and baking mode, through the oven's operation panel or a mobile phone APP.

[0114] More specifically, in the cooking mode, the steam generator operates at maximum steam intensity to fill the inner box 800 with water vapor as quickly as possible, and then adjusts the steam intensity of the steam generator according to the temperature inside the inner box 800 to keep the temperature inside the inner box 800 in dynamic balance with the target temperature.

[0115] More specifically, in the baking mode, the steam generator operates with a relatively small steam intensity, and at the same time controls the heating tubes in the inner box 800 to heat according to the heating mode.
