Description
Technical Field
[0001] This utility model relates to the field of steam oven technology, specifically a steam oven drainage structure. Background Technology
[0002] A steam oven is a multifunctional kitchen appliance that combines steam cooking and baking functions. It can not only bake food like a traditional oven, but also cook food by heating it with steam. It is especially suitable for dishes that need to retain moisture and nutrients, such as vegetables, fish and rice. Through precise temperature control and humidity regulation, steam ovens can achieve a variety of cooking effects, such as crispy on the outside and tender on the inside roasted meat, soft bread and steamed dishes that retain their original flavor. In addition, it can also be used to defrost, ferment dough and heat food. It is an efficient and healthy cooking tool in the modern kitchen.
[0003] When a steam oven is working, the condensate from the steam and the juices from cooking food will be drained through the drain pipe. Most existing steam ovens are equipped with a dedicated drainage system. Users need to clean the drain pan or drain pipe regularly after use to reduce water accumulation, prevent bacteria growth, or prevent water accumulation from affecting the performance of the equipment.
[0004] The existing steam oven equipment still has the following shortcomings: First, after a period of use, the drain hole (connected to a drain pipe for drainage) located on the inner wall of the drain trough at the bottom of the oven often becomes clogged due to the long-term accumulation of oil and water, affecting the normal drainage of the equipment. Summary of the Invention
[0005] Therefore, the purpose of this utility model is to provide a steam oven drainage structure to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a steam oven drainage structure, comprising an oven body, wherein two sets of drainage grooves are symmetrically provided on both sides of the bottom end of the inner wall of the oven body, and two sets of drain holes are symmetrically provided on the inner wall of the drainage grooves, and a cleaning component for cleaning the drain holes is movably installed inside the drainage grooves.
[0007] The cleaning assembly includes a top rod that is movably inserted inside the drain trough. Two sets of sliders are symmetrically fixed to the outer wall of the top rod. Two sets of brushes are symmetrically fixed to the lower surface of each slider, and the bottom end of the brushes is in elastic contact with the bottom end of the inner wall of the drain trough. One side of the oven body is open, and two sets of mounting seats are symmetrically fixed to the outer wall of the oven body near the opening. Gear shafts are rotatably installed inside the two sets of mounting seats.
[0008] By adopting the above technical solution, when the flip cover is rotated open, the gear shaft rotates and meshes synchronously, causing the push rod to move to one side. The push rod simultaneously drives two sets of sliders to move on the inner wall of the drainage channel. The brush scrapes and cleans the surface of the drain hole and the drain outlet. When the flip cover is rotated in the opposite direction to close, the push rod, the two sets of sliders, and the brush move synchronously in the opposite direction to automatically clean the surface of the drain hole and the drain outlet again, preventing oil stains from clogging the drain hole and the drain outlet, ensuring smooth drainage, reducing the manual cleaning steps, and lowering the cleaning difficulty.
[0009] Furthermore, a flip cover is installed on the outer wall of the oven body near the mounting base, and the outer walls on both sides of the flip cover are fixed to the smooth outer wall of the gear shaft by two sets of connecting pieces.
[0010] By adopting the above technical solution, the rotation axis of the flip cover coincides with the central axis of the gear shaft. By rotating the flip cover, the gear shaft can be rotated synchronously, thereby driving the top rod to move back and forth in both directions.
[0011] Furthermore, the slider is slidably connected to the inner wall of the drainage trough, and scraper teeth are fixed at the bottom of the inner wall of the drainage trough and on both sides of the drain hole. Drain outlets are opened on both sides of the outer wall of the scraper teeth.
[0012] By adopting the above technical solution, after the brush cleans the drain hole and the area around the sewage outlet multiple times, a certain amount of water and oil will be attached to its surface. The scraping teeth can remove the dirt when the brush moves to both sides, reducing the attachments on the brush surface. After the attachments are cleaned off, they are swept into the drain hole or sewage outlet by the brush and finally fall into the collection hopper for centralized collection.
[0013] Furthermore, a connecting groove is provided at the bottom of the inner wall of the oven body, and the two sets of drainage grooves are connected through the connecting groove.
[0014] By adopting the above technical solution, the two sets of drainage channels, together with the connecting channel, can expand the area for receiving accumulated water and oil, thus ensuring drainage efficiency.
[0015] Furthermore, both sets of sliders correspond to the positions of the two sets of drain holes. A bucket hole is provided below the mounting base, and the drain hole and the sewage outlet are connected to the inner cavity of the bucket hole. A collection bucket is slidably installed on the inner wall of the bucket hole.
[0016] By adopting the above technical solution, the collecting hopper is tightly fitted to the inner wall of the hopper hole, and a pad for increasing friction is installed at the contact position between the collecting hopper and the inner wall of the hopper hole, which can ensure the connection stability of the collecting hopper and prevent the collecting hopper from sliding out of the hopper hole when the equipment shifts.
[0017] Furthermore, the lower surface of one end of the push rod is provided with teeth, and the push rod penetrates through the oven body and extends into the mounting base, and the toothed part of the push rod meshes with the gear shaft.
[0018] By adopting the above technical solution, the gear shaft consists of a connecting shaft and a gear. The rotation of the flip cover can synchronously drive the gear shaft to rotate, which in turn meshes and drives the top rod, two sets of sliders and brushes to move to one side, thus achieving the effect of automatic cleaning.
[0019] In summary, the present invention has the following main advantages:
[0020] This invention utilizes a mechanism where rotating the flip cover opens the drain, causing the gear shaft to rotate and simultaneously engage, moving the push rod to one side. The push rod then moves two sets of sliders along the inner wall of the drainage channel, while a brush scrapes and cleans the surface of the drain hole and drain outlet. When the flip cover is rotated in the opposite direction to close, the push rod, the two sets of sliders, and the brush move in the opposite direction again to automatically clean the surface of the drain hole and drain outlet, preventing oil stains from clogging them and ensuring smooth drainage. This eliminates the need for manual cleaning and reduces the difficulty of cleaning. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0028] The embodiments of this utility model will be described below based on its overall structure.
[0029] A steam oven drainage structure, such as Figure 1 - Figure 5 As shown, the oven body 1 is provided with two sets of drainage grooves 13 symmetrically opened on both sides of the bottom end of the inner wall of the oven body 1. Two sets of drain holes 131 are symmetrically opened on the inner wall of the drainage grooves 13. A cleaning component 2 for cleaning the drain holes 131 is movably installed inside the drainage grooves 13.
[0030] The cleaning component 2 includes a top rod 21 that is movably inserted inside the drain trough 13. Two sets of sliders 22 are symmetrically fixed on the outer wall of the top rod 21. Two sets of brushes 221 are symmetrically fixed on the lower surface of each slider 22. The bottom end of the brushes 221 is in elastic contact with the bottom end of the inner wall of the drain trough 13. One side of the oven body 1 is open. Two sets of mounting seats 15 are symmetrically fixed on the outer wall of the oven body 1 near the opening. Gear shafts 23 are rotatably installed inside the two sets of mounting seats 15.
[0031] This invention utilizes the principle that when the flip cover 11 is rotated to open, it drives the gear shaft 23 to rotate and simultaneously engages, causing the push rod 21 to move to one side. The push rod 21 simultaneously drives two sets of sliders 22 to move on the inner wall of the drainage groove 13. The brush 221 scrapes and cleans the surface of the drain hole 131 and the drain outlet 132. When the flip cover 11 is rotated in the opposite direction to close, the push rod 21, the two sets of sliders 22, and the brush 221 move in the opposite direction simultaneously to automatically clean the surface of the drain hole 131 and the drain outlet 132 again, preventing oil stains from clogging the drain hole 131 and the drain outlet 132, ensuring smooth drainage, reducing the need for manual cleaning, and lowering the cleaning difficulty.
[0032] Please see Figure 1 - Figure 4 A flip cover 11 is installed on the outer wall of the oven body 1 near the mounting base 15. The outer walls of the flip cover 11 on both sides are fixed to the smooth outer wall of the gear shaft 23 by two sets of connecting pieces. By setting the above structure, the rotation axis of the flip cover 11 coincides with the central axis of the gear shaft 23. By rotating the flip cover 11, the gear shaft 23 can be rotated synchronously, thereby driving the top rod 21 to move back and forth in both directions.
[0033] Please see Figure 1 - Figure 4The slider 22 is slidably connected to the inner wall of the drainage trough 13. The bottom of the inner wall of the drainage trough 13 and both sides of the drain hole 131 are fixed with scraper teeth 24. The outer walls of both sides of the scraper teeth 24 are provided with drain outlets 132. With the above structure, after the brush 221 cleans the drain hole 131 and the area near the drain outlet 132 multiple times, a certain amount of water and oil will be attached to its surface. The scraper teeth 24 can remove the dirt when the brush 221 moves to both sides, reducing the attachments on the surface of the brush 221. After the attachments are cleaned off, they are swept into the drain hole 131 or drain outlet 132 by the brush 221 and finally fall into the collection hopper for collection.
[0034] Please see Figure 1 - Figure 4 The bottom of the inner wall of the oven body 1 is provided with a connecting groove 12, and two sets of drainage grooves 13 are connected through the connecting groove 12. By setting the above structure, the two sets of drainage grooves 13, together with the connecting groove 12, can expand the area for receiving water and oil stains, and ensure drainage efficiency.
[0035] Please see Figure 1 - Figure 5 Both sets of sliders 22 correspond to the positions of the two sets of drain holes 131. A bucket hole 14 is provided below the mounting base 15, and the drain hole 131 and the sewage outlet 132 are both connected to the inner cavity of the bucket hole 14. A collection bucket is slidably installed on the inner wall of the bucket hole 14. By setting the above structure, the collection bucket is tightly fitted to the inner wall of the bucket hole 14, and a pad for increasing friction is installed at the contact position between the collection bucket and the inner wall of the bucket hole 14, which can ensure the connection stability of the collection bucket and prevent the collection bucket from sliding out of the bucket hole 14 when the equipment is shifted.
[0036] Please see Figure 2 - Figure 5 The lower surface of one end of the top rod 21 is provided with teeth, and the top rod 21 passes through the oven body 1 and extends into the mounting base 15. The toothed part of the top rod 21 meshes with the gear shaft 23. By setting the above structure, the gear shaft 23 is composed of a connecting shaft and a gear. The rotation of the flip cover 11 can synchronously drive the gear shaft 23 to rotate, thereby meshing and driving the top rod 21, the two sets of sliders 22 and the brush 221 to move to one side, so as to achieve the effect of automatic cleaning.
[0037] The working principle of this utility model is as follows: When the flip cover 11 is rotated open, it will drive the gear shaft 23 to rotate and simultaneously engage to drive the top rod 21 to move to one side. The top rod 21 simultaneously drives the two sets of sliders 22 to move on the inner wall of the drainage groove 13. The brush 221 is used to scrape and clean the surface of the drain hole 131 and the drain outlet 132. When the flip cover 11 is rotated in the opposite direction to close, the top rod 21, the two sets of sliders 22, and the brush 221 move in the opposite direction to clean the surface of the drain hole 131 and the drain outlet 132 again, to prevent oil stains from clogging the drain hole 131 and the drain outlet 132 and to ensure smooth drainage.
[0038] While the brush 221 moves back and forth, the scraper teeth 24 clean the oil stains attached to the surface of the brush 221. The scraped dirt is then discharged into the collection hopper that is slidably installed in the hopper hole 14 through the drain outlet 132 or the drain hole 131. When it is necessary to deal with the problem, the collection hopper can be pulled out from the hopper hole 14. The cleaning is simple and quick, and it is convenient to centrally treat oil stains and water, thereby improving the cleaning efficiency.
