Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a dishwasher. Background Art

[0002] Dishwashers are divided into two categories: household and commercial. Among them, household fully automatic dishwashers are more suitable for home use, mainly in embedded, tabletop, integrated sink and independent styles. In order to expand the cleaning space, most dishwashers have two or more layers of bowl baskets. Generally, a family consists of about 2-4 people. Therefore, when dining, there are fewer tableware, and only the cleaning space of a single-layer bowl basket can meet the cleaning requirements. However, there are also some special situations of family entertaining, where there are many people dining, resulting in insufficient cleaning space for a single-layer bowl basket. Although the situation of a large number of people dining does not occur frequently, the user experience in these special situations will leave a deep impression on customers due to survivor bias and affect the customer experience. At the same time, these special situations are not common. In most usage scenarios, only a single-layer bowl basket is needed to meet the user's cleaning needs. The space waste and price increase caused by the multi-layer bowl basket are not very cost-effective. Therefore, household dishwashers need to consider how to balance daily use scenarios with occasional special scenarios to improve the customer experience. Utility Model Content

[0027] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. In this specification, the size ratios in the drawings do not represent the actual size ratios, but are only used to reflect the relative position relationship and connection relationship between the components. Components with the same name or the same number represent similar or identical structures and are only for illustrative purposes.

[0028] The utility model provides a dishwasher with a variable cleaning area. The size of the cleaning area can be flexibly adjusted to adapt to different quantities of tableware to be cleaned in different usage scenarios of customers. Figure 1 The figure is an overall schematic diagram of an embodiment of a dishwasher. It includes a cleaning chamber 1 that can be used for washing tableware. The cleaning chamber 1 has an outlet, which is usually arranged on the side or top surface of the cleaning chamber for taking and placing tableware. The cleaning chamber 1 is provided with a door assembly 11 at the outlet, and the door assembly 11 can be sealed with the wall surface 12 around the outlet during operation. Therefore, after the door assembly is closed, when the cleaning operation is performed in the cleaning chamber 1, it can be ensured that all the media for internal cleaning will not spread to the outside of the cleaning chamber. The cleaning chamber 1 has a door assembly 11, which can be closed and sealed with the wall surface 12 of the cleaning chamber 1 during operation. That is, when performing the cleaning operation, after the door assembly 11 is closed, the tableware is cleaned in the cleaning chamber 1 by water and detergent. Among them, the cleaning chamber 1 is also provided with a cleaning area 13 and an extended cleaning area 14. A cleaning basket 131 is provided in the cleaning area 13 for placing tableware for cleaning operations. The extended washing area 14 can be optionally provided with a spare washing basket 141 or a storage box 142. When the spare washing basket 141 is provided, it is used for washing the dishes in the spare washing basket 141, and when the storage box 142 is provided, it is used for storing the dishes in the storage box 142. The switching between the spare washing basket 141 and the storage box 142 can be realized by the user opening the door assembly 11 from the exit, or it can be realized by the device automatically switching according to instructions.

[0029] In daily use, there are fewer people dining at the table, and fewer dishes need to be washed. Only the washing area 13 can be used for washing. At this time, the storage box 142 is placed in the extended washing area 14, and the extended washing area 14 serves as a tableware storage function. The remaining space of the dishwasher is efficiently utilized. In the case of occasional large number of people dining, such as Figure 2 As shown, the storage box 142 can be removed and the tableware stored therein can be used, and then the spare cleaning basket 141 can be placed in the extended cleaning area 14. The extended cleaning area 14 and the cleaning area 13 are both used to clean tableware, ensuring that when the number of tableware is large, all tableware can be cleaned at one time, ensuring the user's usage experience in similar scenarios.

[0030] Figure 3 FIG. 1 is a schematic diagram of the installation of the storage box 142 in the extended cleaning area 14. Figure 4 Schematic diagram of the structure of the spare washing basket 141. Guide rails 21 are provided on the two opposite side walls of the extended washing area 14, and the guide rails 21 extend from the entrance of the extended washing area 14 to the inside of the extended washing area 14. The sides of the spare washing basket 141 and the storage box 142 are provided with support members 22 that can move on the guide rails 21, so that the spare washing basket 141 or the storage box 142 can be in different degrees of opening state (including completely closed state) by the support members 22 staying at different positions on the guide rails 21. The support members 22 are preferably a plurality of rollers provided on both sides of the spare washing basket 141 or the storage box 142. When the spare washing basket 141 or the storage box 142 is pulled out, the rollers roll along the guide rails 21, and the spare washing basket 141 and the storage box 142 can be opened and closed freely. Specifically, in order to ensure that the storage box 142 and the spare washing basket 141 can be stably placed on the guide rail 21 and have a large space for being pulled out and opened, the support member 22 on one side of the storage box 142 or the spare washing basket 141 is preferably provided in three groups: a first roller 22A, a second roller 22B and a third roller 22C. The first roller 22A and the second roller 22B are provided at a certain distance in the pulling direction above the guide rail 21 and at a certain position away from the door assembly 11, and are used to hang the spare washing basket 141 or the storage box 142.

[0031] Since the first roller 22A and the second roller 22B are far away from the door assembly 11, the distance between the first roller 22A, the second roller 22B and the door assembly 11 is sufficient for the spare washing basket 141 or the storage box 142 to be used when it is pulled out, thereby providing a relatively large space for the spare washing basket 141 or the storage box 142 to take and put tableware when it is opened. The second roller 22B is far away from the door assembly 11 relative to the first roller 22A. Another group is arranged below the guide rail 21 and is closer to the second roller 22B relative to the first roller 22A. When tableware is placed in the spare washing basket 141 or the storage box 142, the center of gravity is forward, and the support structure formed by the three groups of support members 22 can ensure that the spare washing basket 141 or the storage box 142 is reliably placed on the support member 22 and will not intrude into the washing area 13 after tilting. In addition, a stopper 211 protruding upward may be provided at one end of the guide rail 21 close to the door assembly 11, and its function is to limit the second roller 22B from sliding out of the guide rail 21, which can prevent the spare washing basket 141 or the storage box 142 from tilting or even falling after the second roller 22B slides out of the guide rail 21. Of course, this does not affect the replacement of the spare washing basket 141 or the storage box 142. When replacing the spare washing basket 141 or the storage box 142, the spare washing basket 141 or the storage box 142 can be lifted to make the second roller 22B leave the guide rail 21, making the stopper 211 invalid, so that the spare washing basket 141 or the storage box 142 can be removed.

[0032] Generally, the dishwasher is also provided with a spray arm 15, which is connected to the extended cleaning area 14 and the cleaning area 13 respectively, and supplies cleaning liquid and the like to the cleaning area 13 and the extended cleaning area 14. In order to adapt to the function switching of the extended cleaning area 14, a valve assembly is provided on the passage of the spray arm 15 connected to the extended cleaning area 14, and the corresponding valve can be opened when the spare cleaning basket 141 is placed in the extended cleaning area 14, so that the cleaning liquid or the gas such as ozone for disinfection can enter not only the cleaning area 13 but also the extended cleaning area 14, that is, the tableware in the spare cleaning basket 141 can be cleaned or disinfected at the same time. In fact, a mechanical switch or an electronic sensing device can also be provided on the side wall of the extended cleaning area 14 or on the door assembly 11 near the extended cleaning area 14, and when the storage box 142 is placed in the extended cleaning area 14, the mechanical switch jumps or the signal of the electronic sensing device jumps, so that the dishwasher senses the existence of the storage box 142 and executes the corresponding program in which the extended cleaning area does not participate in the cleaning. Specifically, a similar switch device may be a mechanical pop-up switch disposed on the wall of the extended washing area 14. When the spare washing basket 141 is used, the pop-up switch is in an open state due to the difference in shape between the spare washing basket 141 and the storage box 142. When the spare washing basket 141 is placed in the storage box 142, the pop-up switch is pressed against to close it, thereby causing the corresponding main control panel to execute a preset lower basket washing procedure. The extended washing area 14 is preferably disposed above the washing area 13, thereby simplifying the design of the washing chamber 1, that is, when only the washing area 13 is used for washing, there is no need to consider the isolation problem between the washing area 13 and the extended washing area 14, because the washing liquid is only concentrated in the washing area 13 due to gravity.

[0033] The storage box 142 may preferably be provided with a detachable storage cover 421, which is used to close the upper opening of the storage box 142, so as to ensure that the internal space of the storage box 142 is relatively independent after being placed in the washing chamber 1, so that the tableware stored therein is not affected by the washing environment in the washing chamber 1. The storage cover 421 can be detachably fixed to the top of the extended washing area 14 when the storage box 142 is loaded, so that the position of the storage cover 421 is relatively fixed and will not move synchronously with the storage box 142, so when the storage box 142 is pulled out to take out and put in tableware, the upper opening of the storage box 142 can be automatically opened. Furthermore, the storage cover 421 is suspended on the top of the extended cleaning area 14 by a rigid rod, such as the bent steel wire in the figure. When the storage box 142 is sent into the storage box 142, the storage cover 421 contacts the sealing strip of the top opening of the storage box 142 and is driven to rotate inward around the fixed point. After the storage box 142 is in place, it rotates to a relatively vertical position of the rigid rod, pressing the storage cover 421 against the opening sealing strip of the storage box 142 to ensure the sealed environment of the storage box 142, thereby ensuring that the internal environment of the storage box 142 is not affected during the cleaning process.

[0034] The dishwasher of the utility model is in a state where the cleaning operation is performed only by the cleaning area 13 during most of the time during its use. At this time, the spare cleaning basket 141 is in an idle state, and the spare cleaning basket 141 needs to be arranged in an additional space. Therefore, in the preferred scheme, the shape and structure of the spare cleaning basket 141 and the cleaning basket 131 can be reasonably designed so that the spare cleaning basket 141 can be stacked in the cleaning basket 131 and as close to the cleaning basket 131 as possible, so that when the cleaning area 13 is usually used for single-area cleaning operations, the spare cleaning basket 141 can be stacked in the cleaning basket 131, and then the tableware is placed on the cleaning basket 131 for cleaning, so that when it is usually used, there is no need to separately accommodate the spare cleaning basket 141. The above embodiment only provides a scheme in which the extended cleaning area 14 is arranged above the cleaning area 13. However, the relative position between the extended cleaning area 14 and the cleaning area 13 does not affect the realization of different functions of the extended cleaning area 14. For example, the cleaning area 13 and the extended cleaning area 14 can also be arranged horizontally side by side. At this time, the cleaning area 13 and the extended cleaning area 14 may not be arranged to be connected as in the above embodiment, but may be isolated from each other, that is, the cleaning control between the cleaning area 13 and the extended cleaning area 14 may be performed without affecting each other, so their position setting does not affect the realization of the above functions.

[0035] The above content is only a description of the preferred implementation mode of the utility model, and does not limit the scope of the utility model. Without departing from the design spirit of the utility model, various modifications and improvements made to the technical solution of the utility model by ordinary technicians in this field should fall within the protection scope determined by the claims of the utility model.
