Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils, in particular to an air blast device and a steam oven. Background Art

[0002] The blower device of the steam oven is usually installed on the outer wall of the inner pot, and can blow air into the inner pot to quickly discharge the steam in the inner pot. When an abnormal situation occurs, the steam in the inner pot may still leak from the blower device and form condensation water on the blower device and other components outside the inner pot, affecting the normal use of the steam oven.

[0003] In the related prior art, a detection element for detecting steam leakage is usually set on the outer wall of the inner tank. However, due to the high temperature of the inner tank, the selection requirements for the detection element are also high, and the cost is high; and the detection element is slow in detecting steam leakage and has low detection accuracy. Utility Model Content

[0004] Based on this, it is necessary to provide a blast device and a steam oven to address the above problems. The blast device can improve the detection accuracy of steam leakage and reduce costs.

[0005] The utility model first provides an air blowing device, comprising: a bracket; a temperature controller, which is arranged on the bracket; an air blowing member, which is arranged on the bracket and spaced apart from the thermostat, the air blowing member is provided with an air inlet and an air outlet, the air inlet faces the thermostat; and a switch component, which is arranged on the air outlet and is used to control the on and off of the air outlet.

[0006] In the above-mentioned blowing device, when a leak occurs at the switch assembly, the steam in the inner tank will flow into the blowing member through the air outlet and out through the air inlet. Since the air inlet is toward the thermostat, the steam flowing out of the air inlet will flow toward the thermostat. When the thermostat detects gas with a higher temperature, it determines that the steam has leaked and feeds back to the user, thereby enabling the thermostat to detect the steam more quickly, thereby improving the timeliness of the thermostat detection and the accuracy of the detection results, and improving the detection accuracy; and, since the temperature at the air inlet of the blowing member is usually lower, the thermostat can use a thermostat with a lower temperature measurement, thereby reducing the cost of the blowing device.

[0007] In one embodiment, the bracket includes a first frame and a second frame connected to each other, the air blowing member is arranged on the first frame, and the air inlet faces the second frame, and the thermostat is arranged on a side of the second frame away from the air blowing member.

[0008] Such an arrangement can reduce the distance between the second frame and the blowing member, thereby preventing the blowing device from occupying too much space inside the steam oven.

[0009] In one embodiment, the first frame includes a bottom wall and two side walls connected to each other in a U-shape, and two ends of the second frame are respectively connected to one end of the two side walls away from the bottom wall; the blowing member is arranged on a side of the bottom wall facing the second frame.

[0010] With such arrangement, the two side walls can ensure the stability and reliability of the connection between the second frame and the first frame, and the outside air can flow to the air inlet through the position where the side walls are not arranged, so as to ensure the normal use of the blowing member.

[0011] In one embodiment, the second frame is perpendicular to the center line of the air inlet.

[0012] Such an arrangement enables the steam flowing out of the air inlet to vertically rush toward the second frame and the thermostat arranged on the second frame, and the thermostat can detect steam leakage in the first place, thereby improving the timeliness of the thermostat detection and the accuracy of the detection result.

[0013] In one of the embodiments, the projection of the thermostat on the air blowing member covers at least a portion of the air inlet.

[0014] Such an arrangement ensures that at least part of the steam flowing out of the air inlet can directly rush to the thermostat, and the thermostat can more obviously detect the steam leakage, thereby improving the accuracy of the thermostat's detection results and improving the detection precision.

[0015] In one embodiment, the second frame is detachably connected to the first frame, and the blowing member is detachably engaged with the first frame.

[0016] With such arrangement, when the blowing member fails, the second frame can be disassembled from the first frame, so that the user can disassemble or repair the blowing member easily.

[0017] In one of the embodiments, the first frame is provided with a plurality of buckles arranged at intervals along the circumference of the blowing member, and the buckles are engaged with a side surface of the blowing member provided with the air inlet.

[0018] Such a configuration can prevent the air blowing member from sliding radially along the air inlet, which would cause the direction of the air inlet to shift relative to the thermostat and affect the accuracy of the detection result; at the same time, it can prevent the air blowing member from sliding axially along the air inlet, which would cause the distance between the second frame and the thermostat and the air inlet to be too small and affect the normal air intake of the air blowing member.

[0019] In one embodiment, the blowing member is configured as a fan; and / or the switch assembly includes an air valve and a transformer for controlling the opening and closing of the air valve; and / or the blowing member is fixed to the bracket by fasteners.

[0020] With such an arrangement, the fan can generate higher wind pressure and air volume to ensure the efficiency of pressurized and forced exhaust in the inner tank; the transformer can adjust the opening size of the air valve, thereby adjusting the opening size of the air outlet to adjust the wind pressure and air volume discharged into the inner tank by the blowing member as needed; the fasteners can ensure the stability and reliability of the connection between the blowing member and the bracket.

[0021] The utility model also provides a steam oven, comprising the blast device as described above.

[0022] In one of the embodiments, the steam oven further includes an inner pot, the blowing device is disposed on an outer side wall of the inner pot, and an air outlet of the blowing member is connected to the inner pot.

[0023] With such an arrangement, the blower device can detect steam leakage in time, preventing the leaked steam from generating condensation water on the blower device and other components outside the inner tank and affecting the normal use of the steam oven, thereby ensuring the safety of the steam oven.

The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0034] The blower in the steam oven can blow air into the inner pot to quickly discharge the steam in the inner pot. A switch is usually provided at the connection between the blower and the inner pot to disconnect the blower and the inner pot when the blower is not working, so as to prevent the steam in the inner pot from being discharged through the blower. When abnormal conditions such as switch abnormality occur, the steam in the inner pot may still leak from the blower and form condensation water on the blower and other components outside the inner pot, affecting the normal use of the steam oven.

[0035] In the related prior art, a detection element for detecting steam leakage is usually set on the outer wall of the inner pot. However, since the temperature of the inner pot is high during the cooking process, the selection requirements for the detection element are also high, and the cost is high. In addition, the detection element is slow in detecting steam leakage, the detection accuracy is low, and there is a safety hazard.

[0036] In order to solve the above problems, Figures 1 to 3 As shown, the utility model first provides an air blowing device, which can improve the detection accuracy of steam leakage and reduce the cost.

[0037] like Figure 1 to Figure 2 As shown, specifically, the air blowing device includes a bracket 1, a thermostat 2, an air blowing member 3 and a switch assembly 4, wherein: the thermostat 2 is arranged on the bracket 1; the air blowing member 3 is arranged on the bracket 1 and is spaced apart from the thermostat 2, the air blowing member 3 is provided with an air inlet 31 and an air outlet 32, and the air inlet 31 faces the thermostat 2; the switch assembly 4 is arranged at the air outlet 32 ​​and is used to control the on and off of the air outlet 32.

[0038] In the blowing device provided by the embodiment of the utility model, since the temperature controller 2 and the blowing member 3 are arranged at an interval, the normal use of the blowing member 3 will not be affected. When the blowing member 3 is working, the switch component 4 connects the air outlet 32 ​​with the inner pot of the steam-bake machine, and the outside air can flow into the blowing member 3 through the air inlet 31, and flow out into the inner pot through the air outlet 32, so as to quickly discharge the steam in the inner pot, thereby playing the role of pressurized strong exhaust; when the blowing member 3 stops working, the switch component 4 disconnects the air outlet 32 ​​and the inner pot; when a leak occurs at the switch component 4, the steam in the inner pot will pass through the air inlet 31, and the steam in the inner pot will be discharged quickly. The air flows into the blowing member 3 through the air outlet 32 ​​and flows out through the air inlet 31. Since the air inlet 31 faces the thermostat 2, the steam flowing out of the air inlet 31 will flow toward the thermostat 2. When the thermostat 2 detects the gas with a higher temperature, it determines that the steam has leaked and feeds back to the user, so that the thermostat 2 can detect the steam more quickly, so as to improve the timeliness of the detection of the thermostat 2 and the accuracy of the detection result, improve the detection accuracy, avoid the leaked steam from generating condensation water on the blowing device and affecting the normal use of the blowing device, and ensure the safety of the use of the blowing device.

[0039] Furthermore, since the temperature at the air inlet 31 of the blowing member 3 is usually low, the thermostat 2 can use a thermostat with a lower temperature measurement, thereby reducing the cost of the blowing device. Moreover, since the temperature difference between the steam and the environment where the thermostat 2 is located is large, the thermostat 2 can also more clearly detect steam leakage.

[0040] like Figure 1 As shown, the air blowing member 3 is configured as a fan. The fan can generate relatively high wind pressure and air volume to ensure the efficiency of pressurizing and exhausting the inner tank, and the fan has a simple structure and is easy to assemble.

[0041] like Figure 1 As shown, in the illustrated embodiment, the switch assembly 4 includes an air valve 41 and a transformer 42 for controlling the opening and closing of the air valve 41. The transformer 42 can adjust the opening size of the air valve 41, thereby adjusting the opening size of the air outlet 32, so as to adjust the wind pressure and air volume discharged from the air blowing member 3 into the inner tank as needed. Of course, other components can also be used to control the opening size of the air valve 41. In other embodiments, the switch assembly 4 can also be set as a one-way valve, so that under normal circumstances, only the air in the air blowing member 3 can flow to the inner tank through the air outlet 32 ​​and the one-way valve, while the air in the inner tank cannot flow into the air blowing member 3 through the one-way valve.

[0042] like Figure 1 to Figure 2 As shown, the blowing device further includes a connecting pipe 6 for connecting the air outlet 32 ​​and the air valve 41 , and the connecting pipe 6 can ensure the sealing between the air outlet 32 ​​and the air valve 41 to avoid gas leakage.

[0043] like Figure 1 As shown, the bracket 1 includes a first frame 11 and a second frame 12 connected to each other, the air blowing member 3 is arranged on the first frame 11, and the air inlet 31 faces the second frame 12, and the thermostat 2 is arranged on a side of the second frame 12 away from the air blowing member 3. Since the thermostat 2 needs to be arranged at a distance from the air blowing member 3, in order to avoid increasing the overall volume of the bracket 1, the thermostat 2 is arranged on a side of the second frame 12 away from the air blowing member 3 to reduce the distance between the second frame 12 and the air blowing member 3, thereby preventing the air blowing device from occupying too much space inside the steam oven.

[0044] The thermostat 2 may be fixed to the second frame 12 by means of screws, bolts and other elements to ensure the stability and reliability of the connection between the thermostat 2 and the second frame 12 .

[0045] like Figure 1 and Figure 3As shown, in the illustrated embodiment, the first frame 11 includes a bottom wall 111 and two side walls 112 connected to each other in a U-shape, and the two ends of the second frame 12 are respectively connected to one end of the two side walls 112 away from the bottom wall 111; the air blowing member 3 is arranged on a side of the bottom wall 111 facing the second frame 12. The bottom wall 111 is used to install and support the air blowing member 3, and the side wall 112 is used to connect the second frame 12, and enable the air inlet 31 of the air blowing member 3 to face the thermostat 2 on the second frame 12. The two side walls 112 can ensure the stability and reliability of the connection between the second frame 12 and the first frame 11, and prevent the second frame 12 and the thermostat 2 from tilting or deviating relative to the air blowing member 3 to affect the accuracy of the detection result. When the air blowing member 3 is working, the outside air can flow to the air inlet 31 through the position where the side wall 112 is not set, so as to ensure the normal use of the air blowing member 3.

[0046] like Figure 1 to Figure 2 As shown, the second frame 12 is detachably connected to the first frame 11, and the air blowing member 3 is detachably connected to the first frame 11. When the air blowing member 3 fails, the second frame 12 can be removed from the first frame 11, so that the user can disassemble or repair the air blowing member 3. The second frame 12 and the first frame 11 can be connected by snapping, plugging or by screws, bolts and other elements to achieve the detachability of the second frame 12 and the first frame 11 while ensuring the stability and reliability of the connection between the second frame 12 and the first frame 11.

[0047] Specifically, the first frame 11 is provided with a plurality of buckles 113 arranged at intervals along the circumference of the blasting member 3, and the buckles 113 are snap-fitted with a side surface of the blasting member 3 provided with the air inlet 31. The plurality of buckles 113 are arranged at intervals along the circumference of the blasting member 3 to ensure the stability and reliability of the connection between the blasting member 3 and the first frame 11, and at the same time, it can also prevent the blasting member 3 from sliding radially along the air inlet 31, causing the direction of the air inlet 31 to shift relative to the thermostat 2, affecting the accuracy of the detection result. The buckles 113 are snap-fitted with a side surface of the blasting member 3 provided with the air inlet 31, which can prevent the blasting member 3 from sliding axially along the air inlet 31, causing the spacing between the second frame 12 and the thermostat 2 and the air inlet 31 to be too small, thereby affecting the normal air intake of the blasting member 3.

[0048] like Figure 1 to Figure 2 As shown, the air blowing member 3 is fixed to the bracket 1 by a fastener 5 such as a screw or a bolt. The fastener 5 and the buckle 113 realize double fixation to further improve the stability and reliability of the connection between the air blowing member 3 and the bracket 1, and ensure that the air inlet 31 of the air blowing member 3 is always facing the thermostat 2, thereby ensuring the accuracy of the detection result of the thermostat 2.

[0049] Of course, in other embodiments, the air blowing member 3 and the bracket 1 can also be fixed only by fasteners 5 such as screws and bolts, as long as the stability of the air blowing member 3 relative to the bracket 1 and the thermostat 2 can be guaranteed, and the embodiments of the utility model are not specifically limited here.

[0050] like Figure 3 As shown, the second frame 12 is perpendicular to the center line L of the air inlet 31. The steam flowing out of the air inlet 31 can vertically rush to the second frame 12 and the thermostat 2 arranged on the second frame 12, and the thermostat 2 can detect the steam leakage in the first time, thereby further improving the timeliness of the detection of the thermostat 2 and the accuracy of the detection result.

[0051] like Figures 2 to 3 As shown, the projection of the thermostat 2 on the blasting member 3 covers at least part of the air inlet 31. It is ensured that at least part of the steam flowing out of the air inlet 31 can directly rush to the thermostat 2, and the thermostat 2 can more obviously detect the steam leakage, thereby further improving the accuracy of the detection result of the thermostat 2 and improving the detection accuracy. Preferably, the projection of the thermostat 2 on the blasting member 3 completely covers the air inlet 31, at which time the steam flowing out of the air inlet 31 can rush to the thermostat 2, and the detection effect is best.

[0052] The embodiment of the utility model further provides a steam oven, comprising the above-mentioned air blowing device.

[0053] Specifically, the steam oven also includes an inner tank, the blast device is arranged on the outer wall of the inner tank, and the air outlet 32 ​​of the blast member 3 is connected to the inner tank. When the blast member 3 is working, it can flow the outside air into the inner tank through the air inlet 31 and the air outlet 32 ​​in sequence, so as to quickly discharge the steam in the inner tank, and play the role of pressurized strong exhaust; when a leak occurs at the switch component 4, the steam in the inner tank will flow out through the air outlet 32 ​​and the air inlet 31 in sequence, and flow toward the thermostat 2. When the thermostat 2 detects a relatively high temperature gas, it determines that the steam has leaked and feeds back to the user. This ensures that the blast device can detect steam leakage in time, avoids the leaked steam from generating condensed water on the blast device and other components outside the inner tank, and affects the normal use of the steam oven, and ensures the safety of the use of the steam oven.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
