Description

Technical Field

[0001] This utility model relates to the technical field of self-cleaning oven equipment, specifically to a self-cleaning oven. Background Technology

[0002] An oven is a heating device used in the heating and drying process of a coating, also known as a drying chamber. Different types of ovens have different structures and heating methods. According to their external structure, they can be divided into box type (drying oven), chamber type (drying room), and through type (which is further divided into straight-through type and bridge type). During long-term use, the oven wall will be covered with debris, and the inner wall of the oven needs to be cleaned regularly. As a result, self-cleaning ovens have been introduced to the market.

[0003] In related technologies, most self-cleaning ovens involve adding an inner chamber inside the oven to dry items. After drying, paint residue may remain on the inner chamber wall. To self-clean the oven, the support frame inside the oven is usually disassembled first, and then the inner chamber is heated at high temperature by the heating components inside the oven. This causes the oil or paint residue on the inner chamber wall to carbonize into slag, which can then be wiped off manually to complete the cleaning.

[0004] However, this cleaning method requires manual collection or sweeping of powder residue. Although it makes the cleaning more thorough, the inner wall of the drying chamber becomes overheated after high-temperature drying, making it inconvenient to clean immediately and thus reducing the cleaning speed of the drying oven. To solve this problem, a spray device has been introduced into the market to clean the surface of the self-cleaning oven. This allows for quick self-cleaning of the oven. However, after installing the spray pipe, the water outlet is often open. During the daily drying process of the oven, paint or oil residue will enter the water inlet pipe, affecting the use of the spray device and reducing the service life of the equipment. To solve the above problems, a self-cleaning oven is proposed. Utility Model Content

[0005] In view of this, the present invention provides a self-cleaning oven. The present invention separates the internal threaded cylinder from the external threaded column, thereby removing the rotating shaft and baffle. The nozzle is disassembled through the internal and external threads, and the plug is installed on all water inlet pipes. This prevents oil or paint from entering the water outlet pipe during daily drying, thereby improving the equipment life.

[0006] To solve the above-mentioned technical problems, this utility model provides a self-cleaning oven, including a sealed chamber fixedly installed on the surface of the self-cleaning inner oven, a box body installed on the surface of the sealed chamber, a box door that can be opened and closed on the front of the box body, multiple water outlet pipes are provided on both the left and right sides of the self-cleaning inner oven, and the water inlet ends of the multiple water outlet pipes on each side are connected to a flushing pipe, a booster pump is provided at the water inlet end of the flushing pipe, a water storage tank is connected at the water inlet end of the booster pump, and an internal thread is provided on the inner ring of the water outlet end of each water outlet pipe.

[0007] Each water outlet pipe is equipped with a plug or nozzle at its outlet end. The nozzle is used when the self-cleaning inner furnace is being cleaned, while the plug is used when the self-cleaning inner furnace is not being cleaned. The plug is used to seal the water outlet pipe when it is not dispensing water, and the nozzle is used to spray the water from the water outlet pipe toward the baffle on the rotating shaft.

[0008] The plug includes an external stud for connecting the knob to the internal thread. The external stud is compatible with the internal thread bolt. A knob is located at the end of the external stud away from the outlet pipe. The knob is rectangular.

[0009] The nozzle includes an external stud for connecting the nozzle to an internal thread. The external stud is adapted to the internal thread bolt. The nozzle is located at the end of the external stud away from the water outlet pipe and is truncated cone-shaped.

[0010] Each booster pump has a support frame at its bottom, which connects the booster pump to the sealing chamber and thus fixes the booster pump. Each support frame is connected to the outer wall of the sealing chamber. The booster pump is connected to the water tank through a water supply pipe, and the water tank is connected to the inner wall of the chamber.

[0011] A sealing ring is embedded in the center of the top of the sealed chamber. The sealing ring is used to insert the heat insulation column, allowing the heat insulation column to rotate within the inner ring of the sealing ring. The heat insulation column is rotatably installed inside the sealing ring. The heat insulation column is used to reduce the high temperature in the self-cleaning inner furnace from being transferred to the rotary motor, thereby improving the service life of the rotary motor. A rotary motor is rotatably installed at the upper end of the heat insulation column, which drives the heat insulation column to rotate.

[0012] The lower end of the heat insulation column passes through the top wall of the self-cleaning inner furnace and is equipped with an internal threaded cylinder. The internal threaded cylinder is used to connect the heat insulation column and the external threaded column. An external threaded column is set at the end of the internal threaded cylinder away from the rotating motor. The external threaded column and the internal threaded cylinder are detachably connected. The external threaded column is used to separate the rotating shaft from the internal threaded cylinder. A rotating shaft is fixedly set at the bottom of the external threaded column. The rotating shaft is used to connect the baffle to the external threaded column. The rotating shaft is made of heat insulation material. Multiple baffles are fixedly set on the surface of the rotating shaft. By rotating the rotating shaft, the baffles throw the water ejected from the water pipe, thereby dispersing the water ejected from the water pipe to various corners of the self-cleaning inner furnace. The water outlet angle of each nozzle is towards the baffle.

[0013] A placement box is fixedly installed on one side wall of the housing. The placement box is used to place components such as nozzles, plugs, and shafts. The shaft and baffle can be placed inside the placement box.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. By separating the internal threaded cylinder from the external threaded column, the shaft and baffle can be removed. The nozzle can be disassembled through the internal and external threads, and the plug can be installed on all water inlet pipes. This prevents oil or paint from entering the water outlet pipe during daily drying, thereby improving the equipment's lifespan.

[0015] 2. The heat insulation column is used to reduce the high temperature inside the self-cleaning inner furnace from being transferred to the rotating motor, thereby improving the service life of the rotating motor. The rotating motor is used to drive the heat insulation column to rotate.

[0016] 3. The internal threaded cylinder is used to connect the heat insulation column and the external threaded column. The external threaded column is used to separate the rotating shaft from the internal threaded cylinder. The rotating shaft is used to connect the baffle to the external threaded column. The baffle and the rotating shaft can be connected as one piece. By rotating the rotating shaft, the baffle throws the water ejected from the water pipe, thereby dispersing the water ejected from the water pipe to various corners of the self-cleaning inner furnace.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0020] like Figure 1-6 As shown: This embodiment provides a self-cleaning oven, including a sealed chamber 101 fixedly disposed on the surface of a self-cleaning inner oven 100. The sealed chamber 101 is used to separate the self-cleaning inner oven 100 from the housing 102. The sealed chamber 101 is made of heat-insulating material. The housing 102 is disposed on the surface of the sealed chamber 101. The inner wall of the housing 102 is coated with a heat-insulating layer. A door 103 is disposed on the front of the housing 102 that can be opened and closed. The door 103 is hinged to the housing 102 by a hinge. A handle is provided on the door 103. Multiple water outlet pipes 200 are provided on both the left and right sides of the self-cleaning inner oven 100. Preferably, each side has a pair of water outlet pipes 200 at the top and bottom. The two water outlet pipes 200 located at the top on the same side are connected, and the two water outlet pipes 200 located at the bottom on the same side are connected. Water pipes 200 are connected together, and then flushing pipes 201 connect the four water outlet pipes 200 on the upper and lower layers. The inlet ends of multiple water outlet pipes 200 on each side are connected to a flushing pipe 201. The flushing pipe 201 is used to replenish water to multiple water outlet pipes 200. A booster pump 202 is installed at the inlet end of the flushing pipe 201. The booster pump 202 is used to increase the head of the spray water. The booster pump 202 is connected to a PLC and connected to the oven host to control the water pressure. A water storage tank 203 is connected at the inlet end of the booster pump 202. The water storage tank 203 is used to store hot water. The water storage tank 203 is made of heat-resistant material. Each water outlet pipe 200 has an internal thread 204 on the inner ring of the water outlet end. The internal thread 204 is embedded in the water outlet end of the water outlet pipe 200.

[0021] When the self-cleaning inner furnace 100 is in use, during daily drying operations, the inner threaded cylinder 403 is separated from the outer threaded column 404, thereby removing the rotating shaft 405 and the baffle 406. The nozzle 301 is disassembled through the inner thread 204 and the outer thread, and the plug 300 is installed on all water inlet pipes. This prevents oil or paint from entering the water outlet pipe 200 during daily drying, thereby improving the equipment's lifespan.

[0022] This embodiment provides a self-cleaning oven. like Figure 1 , 2As shown in Figures 3 and 4: Each water outlet pipe 200 is equipped with a plug 300 or a nozzle 301 at its outlet end. Both the plug 300 and the nozzle 301 are made of heat-insulating material. The nozzle 301 is used at the outlet end of the water outlet pipe 200 when the self-cleaning inner furnace 100 is being cleaned, and the plug 300 is used at the outlet end of the water outlet pipe 200 when the self-cleaning inner furnace 100 is not being cleaned. The plug 300 is used to seal the water outlet pipe 200 when it is not dispensing water. The nozzle 301 is used to spray the water from the water outlet pipe 200 toward the baffle 406 on the rotating shaft 405.

[0023] Its effect is as follows: when the water outlet end of the water outlet pipe 200 is cleaned by the nozzle 301, the water outlet end of the water outlet pipe 200 is not cleaned by the plug 300. The plug 300 is used to block the water outlet pipe 200 when it is not dispensing water. The nozzle 301 is used to spray the water from the water outlet pipe 200 toward the baffle 406 on the rotating shaft 405.

[0024] like Figure 1 , 2 As shown in Figures 3 and 5: The plug 300 includes an external stud 302, which is integrally connected to the knob 304. The external stud 302 is used to connect the knob 304 to the internal thread 204. The external stud 302 and the internal thread 204 are bolt-fitted. The knob 304 is provided at the end of the external stud 302 away from the water outlet pipe 200. The knob 304 is convenient for personnel to rotate. The external stud 302 is connected to the internal thread 204. The knob 304 is rectangular.

[0025] Its effect is that the knob allows personnel to easily rotate the external stud 302 to connect with the internal thread 204. The external stud 302 is used to connect the knob 304 with the internal thread 204, thereby enabling the water inlet pipe and the plug 300 to be detachably connected.

[0026] like Figure 1 , 2 As shown in Figures 3 and 5: The nozzle 301 includes an external stud 302, which is integrally connected to the nozzle 303 or threadedly connected. The external stud 302 is used to connect the nozzle 303 to the internal thread 204. The external stud 302 and the internal thread 204 are bolted together. The nozzle 303 is provided at the end of the external stud 302 away from the water outlet pipe 200. The nozzle 303 is frustum shaped and is used to spray water from the water outlet pipe 200 toward the baffle 406 on the rotating shaft 405.

[0027] Its effect is as follows: the external stud 302 is used to connect the nozzle 303 to the internal thread 204, thereby making the water inlet pipe and the nozzle 301 detachably connected, and the nozzle 303 is used to spray the water from the water outlet pipe 200 toward the baffle 406 on the rotating shaft 405.

[0028] like Figure 1 , 2 As shown in Figures 4 and 5: Each booster pump 202 has a support frame 205 at its bottom. The support frame 205 includes a flat plate and two support plates. The booster pump 202 is mounted on the flat plate, which is welded to the two support plates. The support plates are welded and fixed to the outer wall of the sealing chamber 101. The support frame 205 is used to connect the booster pump 202 to the sealing chamber 101, thereby fixing the booster pump 202. Each support frame 205 is connected to the outer wall of the sealing chamber 101. The booster pump 202 is connected to the water tank 203 through a water supply pipe 107. The water tank 203 is connected to the inner wall of the tank body 102.

[0029] Its effect is that the support frame 205 is used to connect the booster pump 202 to the sealing chamber 101, thereby fixing the booster pump 202.

[0030] like Figure 1 , 2 As shown in Figure 5: A sealing ring 400 is embedded in the center of the top of the sealing chamber 101. The sealing ring 400 is made of high-temperature resistant material. The sealing ring 400 is used to insert the heat insulation column 401, so that the heat insulation column 401 can rotate within the inner ring of the sealing ring 400. The heat insulation column 401 is rotatably arranged inside the sealing ring 400. The heat insulation column 401 is made of heat insulation material. The heat insulation column 401 is used to reduce the high temperature in the self-cleaning inner furnace from being transferred to the rotary motor 402, thereby improving the service life of the rotary motor 402. The rotary motor 402 is rotatably arranged at the upper end of the heat insulation column 401. The rotary motor 402 is made of high-temperature resistant shell. The rotary motor 402 is used to drive the heat insulation column 401 to rotate.

[0031] Its effect is as follows: the heat insulation column 401 is used to reduce the high temperature in the self-cleaning inner furnace that is transferred to the rotary motor 402, thereby improving the service life of the rotary motor 402. The rotary motor 402 is used to drive the heat insulation column 401 to rotate.

[0032] like Figure 1 , 2As shown in Figure 5: The lower end of the heat insulation column 401 passes through the top wall of the self-cleaning inner furnace 100 and is provided with an internally threaded cylinder 403. The internally threaded cylinder 403 has an internal thread that matches the thread on the externally threaded column. The internally threaded cylinder 403 and the heat insulation column 401 can be fixed together by bolts. The internally threaded cylinder 403 is used to connect the heat insulation column 401 and the externally threaded column 404. An externally threaded column 404 is provided at the end of the internally threaded cylinder 403 away from the rotating motor 402. The externally threaded column and the internally threaded cylinder 403 are detachably connected. The externally threaded column 404 is used to separate the rotating shaft 405 from the internally threaded cylinder 403. A rotating shaft 405 is fixedly installed at the bottom. The rotating shaft 405 and the external threaded post 404 can be fixedly connected by bolts. The rotating shaft 405 is used to connect the baffle 406 and the external threaded post 404. The rotating shaft 405 is made of heat insulation material. Multiple baffles 406 are fixedly installed on the surface of the rotating shaft 405. The baffles 406 and the rotating shaft 405 can be connected as one piece. By rotating the rotating shaft 405, the baffles 406 throw the water ejected from the water pipe 200, thereby dispersing the water ejected from the water pipe 200 to various corners of the self-cleaning inner furnace 100. The water outlet angle of each nozzle 301 is towards the baffle 406.

[0033] Its effect is as follows: the internal threaded cylinder 403 is used to connect the heat insulation column 401 to the external threaded column 404, the external threaded column 404 is used to separate the rotating shaft 405 from the internal threaded cylinder 403, the rotating shaft 405 is used to connect the baffle 406 to the external threaded column 404, the baffle 406 and the rotating shaft 405 can be connected as a whole, and by rotating the rotating shaft 405, the baffle 406 throws the water ejected from the water outlet pipe 200, thereby dispersing the water ejected from the water outlet pipe 200 to various corners of the self-cleaning inner furnace 100.

[0034] like Figure 1 , 2 As shown in Figures 5 and 6: The bottom of the self-cleaning inner furnace 100 is connected to a water trough 104. The water trough 104 is used to allow the water outlet pipe 200 to carry carbonized waste residue. The bottom of the water trough 104 is provided with a self-flowing slope. Multiple drain outlets 105 are provided in the center of the bottom of the water trough 104. The bottoms of the multiple drain outlets 105 are connected to a drain pipe 106. The drain pipe 106 passes through the bottom of the box 102 and is provided with a valve. A placement box 500 is fixedly installed on one side wall of the box 102. The top of the placement box 500 is provided with a cover that can be opened and closed. The placement box 500 is used to place components such as the nozzle 301, the plug 300, and the rotating shaft 405. The rotating shaft 405 and the baffle 406 can be placed inside the placement box 500.

[0035] Its function is as follows: the placement box 500 is used to place components such as nozzle 301, plug 300, and rotating shaft 405, thereby facilitating the storage of disassembled components.

[0036] Working principle: When the self-cleaning inner furnace 100 is in operation for daily drying, the inner threaded cylinder 403 is separated from the outer threaded column 404, thereby removing the rotating shaft 405 and baffle 406. The spray head 301 is then disassembled via the inner thread 204 and the outer thread, while the plug 300 is installed on all water inlet pipes. This prevents oil or paint from entering the water outlet pipe 200 during daily drying, preventing damage to the water outlet pipe 200 and affecting the spraying device, thus extending the equipment's lifespan. When the self-cleaning inner furnace 100 needs cleaning, the plug 300 is removed via the inner thread 204 and the outer thread. Install the nozzle 301, then connect the inner threaded cylinder 403 to the outer threaded column 404, thereby connecting the rotating shaft 405 to the heat insulation column 401. Then start the rotary motor 402 to rotate the rotating shaft 405 and the baffle 406, which in turn causes the baffle 406 to throw the water ejected from the water outlet pipe 200, dispersing the water ejected from the water outlet pipe 200 to various corners of the self-cleaning inner furnace 100, thereby automatically cleaning the inner wall of the self-cleaning inner furnace 100. This improves the self-cleaning quality of the furnace and also facilitates the protection of the water outlet pipe 200, thus extending the service life of the equipment.

[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
