Abstract
The invention is an appliance, such as an automatic washer, having a tub in which a wash basket is mounted. The tub comprises an upper and a lower tub member, which are connected by an interference connection. The interference connection is formed by one of the tub members being provided with a peripheral channel and the other tub member being provided with a flange adapted to be received within the channel. Multiple protrusions can extend from one or both of the flange or channel side walls to abut and deflect the flange to form the interference connection.
Claims23
An automatic clothes washer comprising:
- a wash tub defining a chamber adapted to receive a wash basket and the wash tub having an upper tub member with a first peripheral rim and a lower tub member with a second peripheral rim;
- a connection between at least a portion of the first and second peripheral rims to secure together the upper and lower tub members to form the tub;
- and
- the upper tub member and lower tub member having at least one flexible tab with an engagement slot and the other of the upper tub member and the lower tub member has at least one engagement hook corresponding to the flexible tab and aligned with and extending through the engagement slot when the upper and lower tub members are connected by the interference connection to further secure together the upper and lower tub members.
An automatic clothes washer comprising:
- a tub defining a chamber adapted to receive a wash basket, the tub comprising an upper tub member and a lower tub member, the upper tub member having a pan-like body with a first peripheral rim, the lower tub member having a pan-like body with a second peripheral rim corresponding to the first peripheral rim;
- first and second spaced circumferential walls connected by a transverse circumferential wall are formed in the first peripheral rim to define a U-shaped channel;
- a circumferential flange with opposing sides corresponding to the first and second circumferential walls is formed in the second peripheral wall and the circumferential flange sized to be received in the U-shaped channel;
- and
- at least one protrusion extending from one of the side wall and corresponding opposing side a sufficient distance to abut the other of the side wall and corresponding side to provide an interference connection between the upper tub member and the lower tub member.
An automatic clothes washer comprising:
- an elongated tub having a horizontally orientated longitudinal axis, the tub comprising an upper tub member and a lower tub member, the upper tub member having a pan-like body with an upper peripheral rim, the lower tub member having a pan-like body with a second peripheral rim corresponding to the first peripheral rim;
- first and second spaced circumferential walls connected by a transverse circumferential wall formed in the first peripheral rim to define a U-shaped channel;
- a resilient flexible circumferential flange with opposing sides formed in the second peripheral rim and the circumferential flange sized to be received in the U-shaped channel;
- and
- multiple ribs extending from one of the first and second walls and the opposing sides a distance sufficient to contact the other of the first and second walls and the opposing sides and the multiple ribs being alternately disposed on the one of the first and second walls and opposing sides to thereby resiliently flex the flange to provide an interference connection to secure the upper tub member to the lower tub member.
A tub for an appliance comprising:
- an upper tub member having a pan-like body with a first peripheral rim;
- a lower tub member having a pan-like body with a second peripheral rim;
- an interference connection between at least a portion of the first and second peripheral rims wherein the first peripheral rim includes a channel having a pair of side walls and the second peripheral rim includes a flange wherein the channel is sized to receive the flange which is received up into the channel;
- and
- at least one protrusion extending away from the flange a sufficient distance to abut one of the side walls when the flange is received in the channel to form the interference connection.
