Description

Dish washing machine convenient to clean

Technical Field

The invention relates to a kitchen ware, in particular to a novel dish washing machine.

Background

A dishwasher is an apparatus for spraying cold or hot water to dishes waiting for washing to remove dirt adhered thereto for washing. A general dish washer includes a pump and a rotary spray arm to spray washing water, a heater to generate hot water, and the like. In order to save space, many sink-type dishwashers have been developed in the prior art, i.e. the sinks are slightly modified to dishwashers (dishwashers) on the basis of the sinks used in the domestic environment. The existing water tank type dish washer is usually provided with a rotary spray arm at the bottom of the water tank to wash the articles as a water outlet component for washing, and dishes are washed by the water flow sprayed by the rotary spray arm to wait for the washing articles. In most of the existing dish washing machines, if the draining plate needs to be disassembled for cleaning, the draining plate can be taken down after the spraying arm, the water pump and the related connecting structure are disassembled one by one, and the assembly and the disassembly are time-consuming; because the heating element can form dirt such as incrustation scale on the surface after long-term use, the heating element needs to be dismantled for cleaning, and the existing dish-washing machine is designed to cover the draining plate above the bottom of the trough, so that the draining plate needs to be dismantled firstly if the heating element needs to be dismantled, the operation is inconvenient, and the process is complicated; in some existing dish washing machines which utilize an open water pump for water conservancy conveying, the connecting structure between a pump body and a spray arm is complex in design, more in connecting parts, complex in design and inconvenient for opening and assembling products; in addition, although the open water pump reduces the arrangement of the connecting pipeline compared with the traditional water pump, the occupied space of the whole machine is relatively small, but the efficiency of conveying water is limited due to the open space, and the structure of the open water pump still needs to be improved.

Be provided with level sensor and be used for detecting the temperature sensor of internal temperature of cell in basin 1, water inlet assembly 2 is provided with the water injection solenoid valve including the inlet channel 9 that stretches into basin 1 in the inlet channel 9, level sensor and water injection solenoid valve are connected with the controller electricity respectively. In the present embodiment, the heating wire is used as the heating member, and besides the heating wire can be used as the heating member for heating the water tank 1, a heating sheet, a heating paper, and other common heating elements can be used as the heating member. In specific implementation, the heating wires may be disposed on the outer circumference of individual side surfaces of the tank body, i.e., one side surface, two side surfaces, or more side surfaces. Of course, in order to improve the heating effect and efficiency and ensure the uniformity of the heating in the tank body, the heating wires may be disposed on each surface of the periphery of the tank body. The insulating layer can be made of polytetrafluoroethylene or composite silicate heat-insulating coating (manufactured by Chenguan chemical coating Co., Ltd., Tianjin). In specific implementation, the insulating and heat-preserving layer can be attached to the outer side of the heating element and the periphery of the groove body which is not coated by the heating element to preserve heat of the heated groove body. Certainly, the insulating layer also can be the mode spraying of spraying in the heating member outside and by the heat preservation coating of the cell body periphery of heating member cladding, and the thickness of heat preservation coating is 1.5 ~ 10 mm. The water injection electromagnetic valve is a water vapor general type 220V normally closed electromagnetic valve, such as Deleisi 2W 200-20. The heating member is provided to form an oven drying mode in the sink 1 so that the contaminants adhered to the surface of the dishes waiting for washing without being solidified are dried (baked) and then dried to be hardened so as to prepare for the subsequent ultrasonic washing.

Form the purge chamber in basin 1, novel dish washer still sets up the heated air circulation subassembly, the heated air circulation subassembly includes fan 17, connects the hot-blast main 18 between fan and purge chamber, be provided with the heater strip of being connected with the controller electricity in the hot-blast main 18. The purpose that sets up the heated air circulation subassembly is that the drying rate in the basin is accelerated to the steam of utilizing the cell body inner loop hot-blast, taking away the cell body inner loop, and the holistic being heated of cell body is more even for the time of tableware surface filth drying and hardening, has saved abluent total time. When the dish washer is used for washing utensils (dishes and the like) to be washed, if adhesive which is difficult to wash is adhered to the surfaces of the utensils, a heating element arranged on the surfaces of the grooves can be used for heating the grooves, high temperature is formed in the grooves, a hot air circulation assembly is started, water vapor remained in the water grooves is taken away by hot air, the whole bodies in the water grooves are uniformly heated under the assistance of the hot air circulation assembly, residues and other dirt remained on the surfaces of the utensils to be washed are dried and hardened after the water is heated for a certain time, then an ultrasonic generator is started, and the utensils (dishes and the like) to be washed are washed by utilizing the ultrasonic washing principle. The dishwasher of the invention can remove the dirt which has stronger adhesiveness and is difficult to remove, and has better cleaning effect and shorter use time compared with the prior dishwasher. The dish washer is at the in-process of work, utilizes the height of the stoving heating temperature of controller and water level sensor, temperature sensor control cell body and water injection when wasing, and structural design is simple, convenient control.

The upper surface of the tank bottom of the water tank 1 is obliquely arranged so that the upper surface of the tank bottom of the water tank 1 forms a lowest position, a filter hole is formed in the lowest position, a slag basket assembly 10 is installed in the filter hole, and the lower part of the slag basket assembly 10 is communicated with a drain pipe 11. The inclination of the upper surface of the bottom of the water tank 1 means: the upper surface of the bottom of the water tank 1 may be formed of a plurality of inclined slopes, and a connection of the inclined slopes forms a lowest position; alternatively, the upper surface of the tank bottom of the tank 1 may be provided with a conical inclination such that the upper surface of the tank bottom of the tank 1 forms a lowermost position at which the perforations are provided, i.e. at which the slag basket assembly 10 is mounted. The slag basket assembly 10 may be a conventional filter structure (filter residue structure) used in a conventional dishwasher or a dishwasher, and thus, the specific structure of the slag basket assembly 10 will not be described herein. Set up the upper surface of the tank bottom of basin 1 and be the toper slope and enable the upper surface of the tank bottom of basin 1 and form a extreme lower position, the residue filth that washs like this will be along with rivers flow in the unified collection in sediment basket subassembly 10 in the bottom of basin 1, after the dish washer finishes the work, can not remain the residue filth at the tank bottom wall, that is to say follow-up need not to clear up the basin bottom, the basin after the use is cleaner, convenient washing more.

As shown in fig. 7, in order to save the amount of washing water while ensuring the required pumping depth of the pump body, a local depressed area 20 may be formed at the bottom of the water tank 1, and the pump body 25 and the heating member 8 are mounted on the local depressed area 20. After the arrangement, the lower part of the pump body can be ensured to have enough height to extend into water, the using amount of cleaning water for providing water drawing power for the pump body 25 can be effectively saved, the heating speed can be accelerated, the cleaning water can reach the required cleaning temperature in a short time, and the water pump is simple in structural design and efficient in cleaning.
