Description

Gas clothes dryer

Technical Field

The present invention belongs to the technical field of clothes dryers, and in particular, relates to a gas clothes dryer.

Background technique

With the advancement of science and technology, the application of dryers is becoming more and more extensive. Among them, gas dryers need to be connected to an external gas pipe when in use. The air intake pipe inside the dryer is generally connected to the external gas pipe through the air intake port of the air intake pipe. Threads are respectively provided on the air intake port and the gas pipe, and the machine port and the gas pipe are connected through the threads. Therefore, when connecting the gas pipe, the air intake port needs to withstand a certain torque, and the air intake port will transfer the torque it withstands to the entire air intake pipe.

The existing gas dryer air intake pipe often adopts a positioning bracket welded at the air intake port of the air intake pipe to fix the air intake pipe so that the air intake pipe can withstand torque; however, since there are many connection points between the gas valve and the pipeline, it brings great challenges to manufacturing and the manufacturing error is very large, which often causes the gas intake pipe fixing bracket and its matching parts to fail to cooperate normally, and then the connection between the gas valve and the air intake pipe is stressed, affecting the reliability of the connection.

In view of this, the present invention is proposed.

Summary of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a gas dryer. By connecting the air intake port of the air intake pipe with the housing of the dryer and limiting the rotation of the air intake port by the housing of the dryer, the setting of the positioning bracket is eliminated. Relatively speaking, the present invention can allow larger manufacturing errors, avoid stress between the fuel valve and the air intake pipe after installation, and ensure the reliability of the connection.

In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

A gas-fired clothes dryer comprises an air inlet pipe having an air inlet port, the air inlet port passing through a shell of the clothes dryer, a first stop structure being arranged on the air inlet port, a second stop structure being arranged on the shell, the first stop structure being connected to the second stop structure, and being used for limiting the rotation of the air inlet port.

After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

According to a gas dryer of the present invention, the air intake port of the air intake pipe is connected to the shell of the dryer and the rotation of the air intake port is limited by the shell of the dryer, so that the air intake port can withstand torque, thereby eliminating the need for a positioning bracket. Since the gas dryer adopted by the present invention does not need to first match the air intake port with the positioning bracket and then connect it to the shell of the dryer, the air intake port can be adjusted to a larger angle at the dryer shell, which allows for larger manufacturing errors, avoids stress between the fuel valve and the air intake pipe after installation, and ensures the reliability of the connection between the fuel valve and the air intake pipe.

Preferably, the first stop structure is a stop plate provided on the air inlet port, the second stop structure is a through slot that cooperates with the stop plate and penetrates the shell, and the stop plate is engaged in the through slot.

This solution changes the air inlet port into a non-circular structure by providing a stop plate on the air inlet port, and then provides a through groove on the shell, the cross-section of the through groove having the same shape as the cross-section of the non-circular structure. When the stop plate provided on the air inlet port is engaged in the through groove, the air inlet port cannot rotate relative to the shell. Since the shell and the main body of the gas dryer are rigidly connected, the air inlet port can withstand a larger torque.

Furthermore, the stop plate is a square flat plate.

In this solution, the stop plate is set to a plate shape, which is easy to process and manufacture and can effectively save production costs.

Furthermore, the stop plate is welded to the air inlet port.

In this solution, the stop plate is welded to the air inlet port, which simplifies the manufacturing process and helps reduce the manufacturing cost.

Optionally, the first stopping structure is a spline structure provided on the air intake port, and the second stopping structure is a spline groove matched with the spline structure.

Since the spline structure can also transmit torque, the first stop structure in the present invention can also be a spline structure, and the second stop structure is correspondingly set as a spline groove. By adopting this embodiment, the intake port can withstand a larger torque, and the connection between the first stop structure and the intake port is relatively more reliable.

Furthermore, the spline structure is integrally formed with the air intake port.

In this solution, the spline structure is integrally formed with the air intake port, and the spline structure is directly processed when the air intake port is processed, which is beneficial to reduce the number of manufacturing steps and reduce the manufacturing cost.

Furthermore, the shell includes a rear plate and a positioning reinforcement plate connected to the rear plate, a through hole is arranged on the rear plate, and a second stopping structure is arranged on the positioning reinforcement plate corresponding to the position of the through hole.

Furthermore, the positioning reinforcement plate and the rear plate are detachably connected.

In this embodiment, by setting the shell as a detachable structure including a rear plate and a positioning reinforcement plate, after the air intake port is installed, by fine-tuning the positioning reinforcement plate, the rear plate and the positioning reinforcement plate can be clamped to the air intake port, thereby further making the connection between the shell and the air intake port tight.

Furthermore, a valve is provided on the air intake pipe, an air intake pipe fixing plate is provided between the valve and the air intake port, and a bayonet is provided on the air intake pipe fixing plate for clamping the air intake pipe to limit the rotation of the air intake pipe.

Although the first stop structure and the second stop structure are used to enable the intake port to withstand torque, in order to ensure easy installation and allow the installation structure to allow a larger installation error, There is a certain gap between the first stop structure and the second stop structure. When the intake port is subjected to torque, the intake pipe behind the intake port may rotate slightly. In order to further eliminate this rotation, the present invention sets an intake pipe fixing plate between the intake port and the valve.

Furthermore, the air intake pipe fixing plate includes a first plate body and a second plate body, the first plate body is used to connect the clothes dryer, and the bayonet is provided on the second plate body.

The first plate is used to connect with the bottom plate of the clothes dryer, and the second plate is provided with a bayonet for clamping the air inlet pipe. When the air inlet pipe is clamped in the bayonet, it can withstand a small torque, thereby further eliminating the rotation caused by installing an external gas pipe.

The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term " The terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

The gas pipeline installation structure of the clothes dryer 4 provided by the present invention will be described in detail below with reference to FIGS. 1 to 9 .

As shown in Figures 1 to 3, the gas pipeline installation structure of the dryer 4 according to the present invention includes an air intake pipe 1, which has an air intake port 101. The air intake port 101 passes through the shell 2 of the dryer 4 and is connected to the shell 2 of the dryer 4, so that the air intake port 101 can withstand torque.

Specifically, by providing a first stop structure on the air inlet port 101 and then providing a second stop structure corresponding to the first stop structure on the shell 2, the first stop structure is connected to the second stop structure, so that the torque received by the air inlet port 101 can be transmitted to the shell 2. Since the shell 2 is rigidly connected to the main body of the gas dryer 4, in order to rotate the shell 2, the gas dryer 4 must be rotated. The gas dryer 4 is placed on the ground and can therefore withstand a larger torque, thereby causing the air inlet port 101 to withstand a larger torque.

It should be noted that the connection or connection between the first stop structure and the second stop structure mentioned in the present invention does not mean completely preventing the movement of the intake port 101, but limiting the rotation of the intake port 101. Of course, the present invention does not exclude the possibility that the first stop structure and the second stop structure limit other movements of the intake port 101 while limiting the rotation of the intake port 101.

By connecting the air inlet port 101 of the air inlet pipe 1 to the housing 2 of the clothes dryer 4, the rotation of the air inlet port 101 is limited by the housing 2 of the clothes dryer 4, so that the air inlet port 101 can withstand torque, thereby eliminating the need for the positioning bracket. Since the gas pipeline installation structure of the clothes dryer 4 adopted by the present invention does not need to first correspond the air inlet port 101 to the positioning bracket and then connect it to the housing 2 of the clothes dryer 4, the air inlet port 101 can be adjusted at a larger angle at the housing 2 of the clothes dryer 4, which can allow a larger Large manufacturing errors avoid stress between the fuel valve 102 and the intake pipe 1 after installation, thereby ensuring the reliability of the connection between the fuel valve 102 and the intake pipe 1.

Furthermore, the first stop structure is a stop plate 1011 provided on the air inlet port 101, and the second stop structure is a through groove 2012 which cooperates with the stop plate 1011 and passes through the shell 2. In particular, the stop plate 1011 is a square flat plate, wherein the stop plate 1011 is welded to the air inlet port.

In this embodiment, the stop structure of the present invention adopts a fool-proof design, and the stop plate 1011 set in the first stop structure and the corresponding second stop structure are set as a through groove 2012. This not only limits the rotation of the air intake port 101 when connecting to the external gas pipeline, but also facilitates the determination of the angle of the air intake port 101 relative to the shell 2 during installation, thereby avoiding relative misalignment of the air intake port 101 with respect to the valve 102 after installation.

4 to 8 , an embodiment of the present invention using the stop plate 1011 and the through groove 2012 as the connection structure between the air inlet port 101 and the housing 2 will be described in detail.

First, the specific structure of the housing 2 is described with reference to FIGS. 4 to 7 .

As shown in FIG. 4 , the housing 2 includes a positioning reinforcement plate 201 and a rear plate 202 , and the positioning reinforcement plate 201 is detachably connected to the rear plate 202 .

As shown in Figs. 5 to 6, the positioning reinforcement plate 201 includes a first connection hole 2011, a through slot 2012, and a positioning plate 2013. The first connection hole 2011 is used to pass a screw or bolt or other connecting member so that the positioning reinforcement plate 201 is connected to the rear plate 202; the air inlet port 101 can pass through the through slot 2012 to exit the clothes dryer 4; and the positioning plate 2013 is used to connect the positioning reinforcement plate 201 to the rear plate 202 at a unique angle.

Specifically, the through slot 2012 consists of a first through slot 20121 and a second through slot 20122 , the first through slot 20121 accurately corresponds to the stop plate 1011 , and the second through slot 20122 accurately corresponds to the air inlet port 101 , so that the air inlet port 101 can pass through the shell 2 at a unique angle.

As shown in FIG. 7 , the rear plate 202 includes a through hole 2021 , a second connection hole 2022 , and a positioning hole 2023 .

The through hole 2021 corresponds to the through slot 2012 , so that the air inlet port 101 can pass through the through hole 2021 and then pass out of the dryer 4 through the through slot 2012 .

The second connecting hole 2022 corresponds to the first connecting hole 2011, and is used to pass connecting parts such as screws or bolts. After the positioning reinforcement plate 201 and the rear plate 202 are fitted together, connecting parts such as screws or bolts are used to pass through the first connecting hole 2011 and the second connecting hole 2022 in sequence, so as to connect and fix the positioning reinforcement plate 201 and the rear plate 202.

The positioning hole 2023 corresponds to the positioning plate 2013 , so that the positioning reinforcement plate 201 and the rear plate 202 can be connected at a unique angle, thereby ensuring that the through hole 2021 and the through slot 2012 are accurately corresponding.

As shown in Figure 8, a stop plate 1011 is set on the air inlet port 101, wherein the stop plate 1011 is a square flat plate and can be fixed to the air inlet port 101 by welding or other methods; after the air inlet port 101 passes through the through hole 2021 and the through groove 2012 in sequence, the stop plate 1011 is correspondingly located in the first through groove 20121, and the air inlet port 101 is located in the second through groove 20122.

It is worth mentioning that the first through groove 20121 is a square through groove, corresponding to the square structure of the stop plate 1011, and the two sides of the stop plate 1011 are force-bearing edges 10111. When the air intake port 101 receives torque, the force-bearing edges 10111 abut against the upper wall or lower wall on both sides of the first through groove 20121, thereby limiting the rotation of the air intake port 101, so that the air intake port 101 can withstand the torque.

In an optional embodiment of the present invention, the first stopping structure is a spline structure provided on the air intake port 101, and the second stopping structure is a spline groove matched with the spline structure.

Since the spline structure can also transmit torque, the first stop structure in the present invention can also be a spline structure, and the second stop structure is correspondingly set as a spline groove. By adopting this embodiment, the intake port 101 can withstand a larger torque, and the connection between the stop structure and the intake port 101 is also relatively more reliable.

In particular, the spline structure in this solution can be directly formed integrally with the air intake port 101 during manufacturing.

Furthermore, a valve 102 is provided on the intake pipe 1 , and an intake pipe 1 fixing plate is provided between the valve 102 and the intake port 101 . A bayonet 3021 is provided on the intake pipe 1 fixing plate for clamping the intake pipe 1 to limit the rotation of the intake pipe 1 .

Although the first stop structure and the second stop structure are used to enable the intake port 101 to withstand torque, in order to ensure easy installation and allow the installation structure to allow a larger installation error, there will be a certain gap between the first stop structure and the second stop structure. When the intake port 101 is subjected to torque, the intake pipe 1 behind the intake port 101 may rotate slightly. In order to further eliminate this rotation, the present invention sets an intake pipe 1 fixing plate between the intake port 101 and the valve 102.

As shown in Figure 9, the intake pipe fixing plate 3 includes a first plate body 301 and a second plate body 302. The first plate body 301 and the second plate body 302 are vertically arranged. It can be understood that the first plate body 301 and the second plate body 302 form an L-shaped structure, which can be manufactured by a stamping process. At the same time, a reinforcing structure 303 can also be set at the bending position to increase the strength of the intake pipe 1 fixing plate.

The first plate body 301 is used to be connected to the bottom plate 401 of the clothes dryer 4 , and is provided with a clamping plate 3011 , which can be clamped in a long strip through groove provided on the bottom plate 401 .

The clamping plate 3011 includes an abutment plate 30112 and a connecting plate 30111. The abutment plate 30112 can pass through the long strip groove on the base plate 401, and then the upper surface of the abutment plate 30112 abuts against the lower surface of the base plate 401. The connecting plate 30111 is used to connect the abutment plate 30112 and the first plate body 301.

The second plate 302 is provided with a bayonet 3021 for clamping the intake pipe 1. When the intake pipe 1 is clamped in the bayonet 3021, it can withstand a small torque, thereby further eliminating the rotation caused by the installation of an external gas pipe. In particular, the portion where the bayonet 3021 contacts the intake pipe 1 can be provided with a material with greater friction, thereby increasing the friction between the intake pipe 1 and the bayonet 3021.

The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as above in the preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
