Description

A kind of cleaning machine

Technical field

It is especially a kind of for the clear of wash up, vegetables or fruit the utility model relates to a kind of kitchen appliances product Washing machine.

Background technique

With the increasingly raising of people's living standard, dish-washing machine as a kind of kitchen appliances product, more and more into Enter family.Dish-washing machine in the market be generally divided into it is desk-top, cabinet type, three kinds of slot type, wherein table dish-washer be monoblock type independence Structure is typically placed on table top and uses；Cabinet type dish washing machine is also a kind of absolute construction, but needs to be embedded into kitchen cabinet and use； Slot type dish-washing machine is combined together with sink, is typically mounted in kitchen cabinet and is used.

Currently, the water tank cleaner structure of comparative maturity is main as Authorization Notice No. is CN104224074B in the market Chinese patent " water tank cleaner " (application number: CN201310750968.1) is described, that is, includes the cabinet for forming scrubbing space, Cabinet includes water trough body and the cover board that is rotatably connected in water trough body, and the bottom of water trough body at least has in central part Recessed draining region is provided with the water that the water in draining region is pumped out to draining overlying regions scrubbing space in draining region Pump, draining region overlay have the drainboard with drain hole, are in fluid communication with water pump, the rotation gushing arm with apopore is then arranged Above the drainboard.It is covered with the draining region of drainboard by being arranged, and water pump is arranged in draining region, thus by water Pump is isolated with washing zone, makes to flow back into the filtering that the water in water pump first passes through drainboard.

The water trough body of above-mentioned existing water tank cleaner is process using stainless steel material, and processing method is mainly by welding It connects and two kinds of drawing.Wherein, for welding procedure, since the welding deformation amount of stainless steel material is larger, it is difficult to control The precision of sink processed dimensionally, limits the moulded of water trough body, causes water trough body structure single, and then constrain The exploitation of water tank cleaner more multifunction structure, also, requirement of the welding procedure to weld mold is high, welding efficiency is low, It is with high costs；For deep-drawing technique, the deformation limit of stainless steel material directly limits the drawing depth of sink, by drawing The sink that deep technique drawing goes out, sink depth are generally less than the opening width of sink, and the technique in worldwide is difficult at present To do the opening width that the drawing depth of screw clamp is greater than groove body, this results in sink to occupy the biggish peace in kitchen during installation Space is filled, and greatly limits the scrubbing space of sink.

Utility model content

For the current state of the art, the technical problem to be solved by the utility model is to provide a kind of using plastics and gold Symbolic animal of the birth year combine groove body so as to deepen groove body depth, reduce production cost cleaning machine.

Another technical problem to be solved in the utility model is the status for the prior art, and providing a kind of can prevent Plastic groove deformation, the cleaning machine for improving condensation effect after cleaning.

Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of cleaning machine, including there is washing The water trough body of chamber, it is characterised in that: the water trough body is plastic material, further includes metalwork, and the metalwork is set to water On the inner wall of slot body upper part, lower part is at least provided with multiple spaced apart protrusions on the inner wall of the water trough body Portion.

Preferably, protrusion is arranged on the internal perisporium of water trough body in array.

Preferably, the flow guide bar extended up and down is convexly equipped on the inner wall of the metalwork.The structure can by condensed water to Lower guidance is conducive to the condensation for accelerating water.

For the ease of installation, accommodation groove circumferentially is offered on the inner wall on the water trough body top, it is described Metalwork be set to the accommodation groove in.The structure is convenient for carrying out location and installation to metalwork.

Preferably, the metalwork is configured in accommodation groove the annular slab extended up and down, the upper edge of the annular slab with The upper limb of the accommodation groove is in contact, and the lower edge of the annular slab is in contact with the lower edge of the accommodation groove.

Further preferably, the upper edge of the annular slab is bent to form the first U-shaped of opening down arrangement into accommodation groove Structure, the outside of first U-shaped structure are in contact with the inner wall of accommodation groove, the lower edge of annular slab bent into accommodation groove At the second U-shaped structure for having opening up arrangement, the outside of second U-shaped structure is in contact with the inner wall of accommodation groove, the ring The first U-shaped structure, the second U-shaped structure on shape plate and the annular slab are formed as the first cavity between accommodation groove inner wall jointly. Since hot water is mainly sprayed after spray arm sprays to the inner wall of water trough body middle and upper part, and hot steam rises to sink On the one hand bodies top, above-mentioned first cavity can be improved the thermal insulation property of water trough body lower part, energy saving, on the other hand, Soundproof effect can be played to a certain extent.

Preferably, it corresponds to be recessed inwardly at flow guide bar in the outside wall surface of the annular slab and is formed with depressed area.At flow guide bar Recessed structure largely enhances the elasticity of annular slab outside convex, and super when cleaning machine enables ultrasonic cleaning equipment Sound wave forms stronger resonance, improves cleaning effect.

Preferably, the region of corresponding accommodation groove is provided with the first reinforcing rib on the periphery wall of the water trough body.Setting The structure improves the rigidity on water trough body top, leads to water trough body deforming tops to avoid high temperature.

Preferably, the open position of the water trough body is at least metal material in the position contacted with mounting plane, The water trough body position of lower section is then plastic material.During installation due to current water trough body, water trough body top is generally used Portion edge is as load-bearing position, using the above structure, to improve the stability of water trough body installation.

For the ease of installing and improving the stability after installation, the open periphery of the water trough body is provided with for installing And the metal assembling frame of load-bearing.

Preferably, the open edge extends outward to form the shelf that can be shelved on mounting plane, the metal dress Open periphery with frame around water trough body arranges that section at least has Z-shape part, wherein Z-shaped following lining is located at Under shelf, Z-shaped vertical edge is disposed around outside the periphery of shelf, and Z-shaped top is then gradually distance from shelf and extends outwardly.The metal The top of the Z-site of assembling frame has the outer vertical edge that bends downward in extending end, the bottom of the outer vertical edge with it is described Z-shaped Position it is following concordant.To further increase the stability after installation.

Preferably, the inner wall of the metalwork and the inner wall of water trough body are flush.

In the above embodiments, the bottom of the water trough body is provided with ultrasonic generator.The structure can be mentioned effectively High cleaning effect, and in the metalwork of plastic groove top setting, and resonance can be generated with ultrasonic generator, further mention High ultrasound cleaning effect.
