Abstract
Description
Technical Field
[0001] This utility model relates to the field of microwave steam oven technology, and in particular to a steam exhaust structure and a microwave steam oven. Background Technology
[0002] When a microwave steam oven is cooking, steam fills the entire steam-baking chamber. At this time, the pressure inside the chamber is greater than the external air pressure. For safety reasons, a steam vent is usually made on the side wall of the steam-baking chamber to release steam and reduce pressure, allowing the steam inside the chamber to be released into the external environment in a timely manner. Currently, the vent is directly located on the cavity (back panel or side panel), which is inconvenient and costly to drill in such a large area. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a steam exhaust structure and a micro steam oven that is easy to drill and has low cost.
[0004] To achieve the above objectives, the technical solution of this utility model is: a steam exhaust structure, including a steam exhaust hole and a fan fixing plate disposed on the cavity, wherein the steam exhaust hole is disposed on the fan fixing plate.
[0005] With the above structure, this utility model has the following advantages compared with the prior art: the exhaust hole is directly set on the fan fixing plate, so there is no need to drill holes in the large area of the cavity. Drilling is convenient, quick and easy and low cost.
[0006] Preferably, it also includes a steam vent pipe installed at the steam vent, which allows steam to be vented to the outside.
[0007] Preferably, it also includes a connecting sleeve, one end of which is installed on the vent hole, and one end of the vent pipe is sleeved on the other end of the connecting sleeve. The connecting sleeve facilitates fixing the vent pipe to the vent hole.
[0008] Preferably, the outer side of one end of the connecting sleeve is provided with a limiting protrusion protruding from the outer side of the connecting sleeve; when the connecting sleeve is installed in the exhaust hole, the limiting protrusion abuts against the surface of the fan fixing plate. The limiting protrusion prevents the connecting sleeve from being carried away from the fan fixing plate by the exhaust pipe, thus ensuring high reliability.
[0009] Preferably, the connecting sleeve is interference-fitted with the vent hole, ensuring a reliable connection.
[0010] Preferably, the exhaust port is located on the fan mounting plate away from the fan to prevent interference between the exhaust port and the fan.
[0011] A microwave steam oven includes a steam exhaust structure as described in any of the above claims, and further includes a cavity, wherein a fan mounting plate is mounted on the cavity, and a fan is mounted on the fan mounting plate.
[0012] Preferably, the fan mounting plate is located on the top, side, or back of the cavity.
[0013] Preferably, the fan mounting plate is detachably connected to the cavity. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] Figure 1 This is a perspective view of a steam exhaust structure according to this utility model, as shown below. Figure 1 In the embodiment shown, the present invention provides a steam exhaust structure, including a fan fixing plate 2 disposed on the cavity 5, and a steam exhaust hole 1 disposed on the fan fixing plate 2. Only a small area of the fan fixing plate 2 needs to be drilled, which is convenient and quick. It is not necessary to drill holes on a large area plate, so as not to damage the strength of the large area plate.
[0021] As an example, in order not to affect the normal operation of the fan, the exhaust port 1 is located at a position away from the fan on the fan mounting plate 2, so that there is no interference between the exhaust port 1 and the fan.
[0022] Figure 2 This is a perspective view of the connection between the exhaust structure and the exhaust pipe of this utility model, as shown below. Figure 2 In the illustrated embodiment, the exhaust structure also includes an exhaust pipe 3, one end of which is installed at the exhaust port 1, allowing steam to be exhausted to the outside. The fan is bolted to the fan mounting plate 2, and the fan and the exhaust pipe 3 are located on the same side of the fan mounting plate 2.
[0023] Combination Figure 1 and 2 Furthermore, it also includes a connecting sleeve 4, which is snapped onto the vent hole 1, allowing one end of the vent pipe 3 to be fitted onto the connecting sleeve 4. This facilitates the installation and removal of the vent hole 1. Simultaneously, due to the connecting sleeve 4, the vent pipe 3 does not directly contact the steam, preventing it from being damaged by heat and extending its service life. Specifically, the connecting sleeve 4 is made of heat-resistant materials, such as copper, iron, or aluminum.
[0024] As one embodiment, the connecting sleeve 4 and the vent hole 1 are interference fit, so the connecting sleeve 4 is not easy to detach from the vent hole 1, and the connection is reliable.
[0025] Figure 3 This is a perspective view of a steam exhaust structure connecting sleeve according to this utility model, as shown below. Figure 3 In the illustrated embodiment, to prevent the connecting sleeve 4 from detaching from the fan mounting plate 2, a limiting protrusion 410 is provided on the outer side of one end of the connecting sleeve 4. The limiting protrusion 410 protrudes from the outer side of the connecting sleeve 4 and abuts against the side of the fan mounting plate 2. The limiting protrusion 410 and the exhaust pipe 3 are located on the inner and outer sides of the fan mounting plate 2, respectively. In this way, the limiting protrusion 410 can prevent the connecting sleeve 4 from detaching from the fan mounting plate 2 by the exhaust pipe 3 in a direction closer to the exhaust pipe 3. The exhaust pipe 3, being fitted onto the connecting sleeve 4, can also prevent the connecting sleeve 4 from detaching from the fan mounting plate 2 in a direction away from the exhaust pipe 3, resulting in high reliability. Specifically, the limiting protrusion 410 is an annular protrusion, which has a larger contact area with the fan mounting plate 2, resulting in a better limiting effect.
[0026] Figure 4 This is a perspective view of the steam exhaust structure of this utility model applied to a microwave steam oven, as shown. Figure 4 In the illustrated embodiment, it further includes a cavity 5, a fan mounting plate 2 mounted on the cavity 5, and a fan mounted on the fan mounting plate 2. Specifically, the fan mounting plate 2 is mounted on the cavity 5 by bolts.
[0027] Specifically, the fan mounting plate 2 can be located on the top, side or back of the cavity 5.
[0028] Specifically, the principle of this utility model is to directly set the exhaust hole 1 on the fan fixing plate 2, so that there is no need to drill holes in the large area cavity 5. Drilling is convenient, quick and cheap.
[0029] Operation process: First, install the connecting sleeve 4 inside the vent hole 1, at which point the limiting protrusion 410 abuts against the side of the fan fixing plate 2; then, put the vent pipe 3 onto the connecting sleeve 4. In this way, the steam inside the steam oven cavity is discharged to the external environment in a timely manner through the vent hole 1 and the vent pipe 3. There is no need to drill holes in the large area of the cavity 5, drilling is convenient and quick, and does not affect the heating effect.
[0030] Based on the above solutions, if any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
