Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a clothes dryer. Background Art

[0002] In the existing design of dryers, the connection between the drum front plate and the base is usually achieved through fasteners such as bolts. During the installation process, this connection method requires precise alignment of the position of the bolt connection hole so that the bolt can be screwed on, which will cause some difficulties in the actual assembly process. Therefore, a pre-positioning structure is usually used to pre-position the drum front plate and the base. However, the existing pre-positioning structure has alignment difficulties during the actual installation process, resulting in an unsmooth pre-positioning process and reduced assembly efficiency. In addition, the existing pre-positioning structure also has the problem of unstable position. Even after alignment, the position of the pre-positioning structure may shift due to various factors, resulting in pre-positioning failure. This instability will not only affect the installation of subsequent fasteners, but also reduce the stability and reliability of the entire dryer. Utility Model Content

[0003] In order to solve the problems encountered in the prior art during the assembly of a drum front plate and a base, the utility model provides a clothes dryer, which can realize rapid pre-positioning and connection of the drum front plate and the base, thereby improving assembly efficiency.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A clothes dryer comprises a casing, the casing comprising a base and a drum front plate, the drum front plate standing on the front side of the base, the bottom of the front side of the base protruding forward to form a boss, the boss and the front side of the base form an assembly space for the drum front plate, a first connecting member and a first positioning member are provided on the drum front plate, a second connecting member and a second positioning member are provided on the base, the boss is configured to support the drum front plate while enabling the drum front plate to translate forward and backward relative to the base, the first positioning member and the second positioning member are laterally plugged in and connected for pre-positioning the connection of the first connecting member and the second connecting member.

[0006] In the above technical solution, the bottom of the front side of the base protrudes forward to form a boss, and the boss and the front side of the base form an assembly space for the drum front plate, so that the drum front plate can be translated forward and backward relative to the base, which is convenient for installation and disassembly. At the same time, the lateral plug-in connection of the first positioning member and the second positioning member can pre-position the connection position of the first connecting member and the second connecting member, and the boss provides vertical support for the drum front plate, which effectively avoids the drum front plate from flipping relative to the base. After the first positioning member and the second positioning member are pre-positioned, as long as the drum front plate is not subjected to lateral external forces, it can be stably connected to the base. This design eliminates the need for the assembler to hold the drum front plate all the time during the installation process, freeing up both hands and facilitating the installation of fasteners at the positions of the first connecting member and the second connecting member to fix the drum front plate to the base.

[0007] Preferably, the boss includes a boss body and a plurality of support ribs spaced apart along the left-right direction, the support ribs extending along the front-back direction and arranged on the upper end surface of the boss body, and the support ribs are supported on the lower end surface of the drum front plate.

[0008] In the above technical solution, the plurality of support ribs can provide multi-point support for the front plate of the drum. This multi-point support method can provide a more stable and reliable support effect, so that the front plate of the drum can be more stably assembled and fixed on the base. Compared with the solution of using the entire large plane for support, the support method adopted in this solution can reduce the flatness requirements on the upper end surface of the boss. Only the height and flatness of the support ribs need to be required, thereby reducing the processing difficulty, reducing the processing cost, and improving production efficiency.

[0009] Preferably, the first connecting member is provided with a first connecting hole, the second connecting member is provided with a second connecting hole, and when the drum front plate is predetermined to be located on the base, the first connecting member is pressed against the corresponding second connecting member, and the first connecting hole is aligned with the corresponding second connecting hole.

[0010] In the above technical solution, the first connection hole and the second connection hole are used to install the fastener. When the drum front plate is predetermined to be located at the base, the first connection hole is aligned with the corresponding second connection hole, which can facilitate the rapid alignment and installation of the fastener, reduce assembly time, and improve assembly efficiency.

[0011] Preferably, the left and right edges of the drum front plate are extended backward to form side extension plates, the inner side of the side extension plate is provided with a reinforcement portion composed of a plurality of ribs, the first positioning piece is provided on the inner side of the reinforcement portion, and the second positioning piece is provided on the left and right side walls of the base.

[0012] In the above technical solution, the side extension plate can wrap the base part, and the wrapping effect of the side extension plate makes the connection between the base and the drum front plate more firm, ensuring the stability and reliability of the dryer. At the same time, the design of the reinforcement part can provide additional support to ensure that the connection position of the first positioning member and the second positioning member is more stable and reliable. By arranging the first positioning member on both the left and right sides of the drum front plate, the first positioning member and the second positioning member can be positioned left and right. This design ensures the correct alignment of the dryer during the assembly process and improves the assembly efficiency and accuracy.

[0013] Preferably, the first positioning member is a positioning protrusion, and the second positioning member is a laterally extending positioning groove, the front end of the positioning groove is opened, and when the drum front plate is installed on the base, an avoidance gap is provided between the rear end surface of the first positioning member and the rear end surface of the second positioning member.

[0014] In the above technical solution, after the first positioning member and the second positioning member are pre-positioned, the avoidance gap can prevent them from causing excessive connection to the abutment between the first connecting member and the second connecting member. This design can avoid the problem of over-positioning and ensure the correct abutment between the first connecting member and the second connecting member.

[0015] Preferably, the rear end of the first positioning member extends rearwardly beyond the rear end of the reinforcement portion.

[0016] In the above technical solution, since the rear end of the first positioning member extends backward beyond the rear end of the reinforcement portion, the position of the first positioning member can be easily observed during assembly. This design makes it easier for assemblers to determine the correct position of the first positioning member, thereby more conveniently aligning the first positioning member with the second positioning member, which can reduce errors and unnecessary adjustments during assembly. This design helps to improve assembly efficiency, shorten assembly time, and reduce production costs.

[0017] Preferably, the length of the first positioning member in the vertical direction increases from the rear end to the front end, and the length of the second positioning member in the vertical direction decreases from the front end to the rear end.

[0018] Due to the arrangement in the above technical solution, there is a gap between the first positioning member and the second positioning member in the vertical direction in the initial stage of assembly, and this gap will gradually decrease during the assembly process. Due to the existence of this gap, the first positioning member and the second positioning member can move relative to each other in the initial stage, providing a positioning guide. This design enables the assembler to more conveniently align the first positioning member with the second positioning member and ensure their correct connection. The existence of the gap also allows the first positioning member and the second positioning member to have a certain degree of flexibility during the assembly process, and can adapt to different positions and angles. This flexibility makes the assembly process easier and more convenient, thereby improving assembly efficiency. At the same time, as the gap gradually decreases, the abutment between the first positioning member and the second positioning member becomes more accurate, providing more precise positioning and connection. This further ensures the accurate installation between the front plate of the drum and the base.

[0019] Preferably, the distance between the two second positioning members increases from the front end to the rear end, and the distance between the two first positioning members decreases from the rear end to the front end. When the drum front plate is predetermined to be located on the base, the inner side wall of the first positioning member is in close contact with the bottom side wall of the second positioning member.

[0020] Due to the arrangement in the above technical solution, there is a gap between the first positioning member and the second positioning member in the left-right direction in the initial stage of assembly, and this gap will gradually decrease during the assembly process. Due to the existence of this gap, the first positioning member and the second positioning member can move relative to each other in the initial stage, providing a positioning guide. This design enables the assembler to more conveniently align the first positioning member with the second positioning member and ensure their correct connection. The existence of the gap also allows the first positioning member and the second positioning member to have a certain degree of flexibility during the assembly process, and can adapt to different positions and angles. This flexibility makes the assembly process easier and more convenient, thereby improving assembly efficiency. At the same time, as the gap gradually decreases, the abutment between the first positioning member and the second positioning member becomes more accurate, providing more precise positioning and connection. This further ensures the accurate installation between the front plate of the drum and the base.

[0021] Preferably, the first positioning member is a transversely extending positioning groove, the rear end of which is open, and the second positioning member is a positioning protrusion. The solution can achieve pre-positioning cooperation between the first positioning member and the second positioning member.

[0022] Preferably, the first positioning member is arranged above the boss.

[0023] In the above technical solution, since the first positioning member is arranged above the boss, the first positioning member is relatively far away from the boss, thereby providing better positioning support. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Embodiment 1:

[0032] like Figures 1 to 5 As shown, a clothes dryer includes a casing 10, and the casing 10 includes a base 1 and a drum front plate 2. The drum front plate 2 stands on the front side of the base 1. The bottom of the front side of the base 1 protrudes forward to form a boss 1.3. The boss 1.3 and the front side of the base 1 form an assembly space 1.4 for the drum front plate 2. A first connecting member 2.3 and a first positioning member 4 are provided on the drum front plate 2. The base 1 is provided with a second connecting member 1.1 and a second positioning member 3. The boss 1.3 is constructed to support the drum front plate 2 while enabling the drum front plate 2 to translate forward and backward relative to the base 1. The first positioning member 4 and the second positioning member 3 are laterally plugged in and connected for pre-positioning the connection between the first connecting member 2.3 and the second connecting member 1.1. The first positioning member 4 is arranged above the boss 1.3. In order to facilitate readers to see the structure clearly, Figure 3 The drum front plate and base have part of the structure removed. Figure 4 The drum front plate in the figure has part of its structure cut away.

[0033] In the above technical solution, the bottom of the front side of the base 1 is convex to form a boss 1.3, and the boss 1.3 and the front side of the base 1 form an assembly space 1.4 for the drum front plate 2, so that the drum front plate 2 can be translated forward and backward relative to the base 1, which is convenient for installation and disassembly. At the same time, the lateral plug-in connection of the first positioning member 4 and the second positioning member 3 can pre-position the connection position of the first connecting member 2.3 and the second connecting member 1.1, and provide vertical support for the drum front plate 2 in combination with the boss 1.3, effectively avoiding the drum front plate 2 from flipping relative to the base 1. After the first positioning member 4 and the second positioning member 3 are pre-positioned, as long as the drum front plate 2 is not subjected to lateral external forces, it can be stably connected to the base 1. This design makes it unnecessary for the assembler to hold the drum front plate 2 all the time during the installation process, freeing both hands, and conveniently installing fasteners at the first connecting member 2.3 and the second connecting member 1.1 to fix the drum front plate 2 to the base 1. Since the first positioning member 4 is arranged above the boss 1.3, the first positioning member 4 is relatively far away from the boss 1.3, so as to better perform positioning and support.

[0034] In this embodiment, the boss 1.3 includes a boss body 1.3.0 and a plurality of support ribs 1.3.1 arranged at intervals along the left-right direction, the support ribs 1.3.1 extending along the front-back direction and arranged on the upper end surface of the boss body 1.3.0, and the support ribs 1.3.1 supported on the lower end surface of the drum front plate 2. The plurality of support ribs 1.3.1 can provide multi-point support to the drum front plate 2, and this multi-point support method can provide a more stable and reliable support effect, so that the drum front plate 2 can be more stably assembled and fixed on the base 1. Compared with the scheme of using the entire large plane for support, the support method adopted in this scheme can reduce the flatness requirements for the upper end surface of the boss 1.3. Only the height and flatness of the support ribs 1.3.1 need to be required, thereby reducing the processing difficulty, reducing the processing cost, and improving production efficiency.

[0035] In this embodiment, the number of the first connecting members 2.3 is several, and the number of the second connecting members 1.1 is several and corresponds to the first connecting members 2.3 one by one. The first connecting member 2.3 is provided with a first connecting hole 1.2, and the second connecting member 1.1 is provided with a second connecting hole 2.4. When the drum front plate 2 is predetermined to be located on the base 1, the first connecting member 2.3 is pressed against the corresponding second connecting member 1.1, and the first connecting hole 1.2 is aligned with the corresponding second connecting hole 2.4. The first connecting hole 1.2 and the second connecting hole 2.4 are used to install fasteners. When the drum front plate 2 is predetermined to be located on the base 1, the first connecting hole 1.2 is aligned with the corresponding second connecting hole 2.4, which can facilitate the rapid alignment and installation of the fasteners, and can reduce the assembly time and improve the assembly efficiency.

[0036] Preferably, the edges of the left and right sides of the drum front plate 2 are extended backward to form side extension plates 2.1, and the inner side of the side extension plate 2.1 is provided with a reinforcement part 2.2 composed of a plurality of ribs, and the first positioning member 4 is provided on the inner side of the reinforcement part 2.2, and the left and right side walls of the base 1 are provided with the second positioning member 3. In the above technical scheme, the side extension plate 2.1 can partially wrap the base 1, and the wrapping effect of the side extension plate 2.1 makes the connection between the base 1 and the drum front plate 2 more firm, ensuring the stability and reliability of the dryer. At the same time, the design of the reinforcement part 2.2 can provide additional support to ensure that the connection position of the first positioning member 4 and the second positioning member 3 is more stable and reliable. By arranging the first positioning member 4 on both the left and right sides of the drum front plate 2, the left and right positioning of the first positioning member 4 and the second positioning member 3 can be achieved. This design ensures the correct alignment of the dryer during the assembly process and improves the assembly efficiency and accuracy.

[0037] It can be understood that in one embodiment, the first positioning member 4 is a positioning protrusion, and the second positioning member 3 is a positioning groove extending laterally, and the front end of the positioning groove is open. When the drum front plate 2 is installed on the base 1, an avoidance gap 5 is provided between the rear end face of the first positioning member 4 and the rear end face of the second positioning member 3. The rear end of the first positioning member 4 extends backward beyond the rear end of the reinforcing portion 2.2. The length of the first positioning member 4 in the vertical direction increases from the rear end to the front end, and the length of the second positioning member 3 in the vertical direction decreases from the front end to the rear end. The distance between the two second positioning members 3 increases from the front end to the rear end, and the distance between the two first positioning members 4 decreases from the rear end to the front end. When the drum front plate 2 is predetermined to be located on the base 1, the inner side wall of the first positioning member 4 is in close contact with the bottom side wall of the second positioning member 3.

[0038] In the above technical solution, after the first positioning member 4 and the second positioning member 3 are pre-positioned, the avoidance gap 5 can prevent them from excessively connecting the abutment between the first connecting member 2.3 and the second connecting member 1.1. This design can avoid the problem of over-positioning and ensure the correct abutment between the first connecting member 2.3 and the second connecting member 1.1. Since the rear end of the first positioning member 4 extends backward beyond the rear end of the reinforcing portion 2.2, the position of the first positioning member 4 can be easily observed during assembly. This design makes it easier for assemblers to determine the correct position of the first positioning member 4, so that it is more convenient to align the first positioning member 4 with the second positioning member 3, which can reduce errors and unnecessary adjustments during assembly. This design helps to improve assembly efficiency, shorten assembly time, and reduce production costs. Due to the arrangement in the above technical solution, there is a gap between the first positioning member 4 and the second positioning member 3 in the vertical direction in the initial stage of assembly, and this gap will gradually decrease during the assembly process. Due to the existence of this gap, the first positioning member 4 and the second positioning member 3 can move relative to each other in the initial stage, providing a positioning guide effect. This design enables the assembler to more conveniently align the first positioning member 4 with the second positioning member 3 and ensure their correct connection. The presence of the gap also allows the first positioning member 4 and the second positioning member 3 to have a certain flexibility during the assembly process, and can adapt to different positions and angles. This flexibility makes the assembly process easier and more convenient, thereby improving the assembly efficiency. At the same time, as the gap gradually decreases, the abutment between the first positioning member 4 and the second positioning member 3 is more accurate, providing more precise positioning and connection. This further ensures the accurate installation between the drum front plate 2 and the base 1.

[0039] It is understandable that in another embodiment, the first positioning member 4 is a transversely extending positioning groove, the rear end of the positioning groove is open, and the second positioning member 3 is a positioning protrusion. The solution can achieve pre-positioning cooperation between the first positioning member 4 and the second positioning member 3.
