Description

A mounting structure and dish washer for last sensor of dish washer

Technical Field

The utility model relates to the technical field of dish washers, in particular to a mounting structure of a sensor used on a dish washer and the dish washer.

Background

The existing dish washing machine generally has a storage function, and part of high-end machine types can even replace part of disinfection cabinets, so that tableware can be stored for a long time, and the trouble that the tableware is transferred after washing the dishes is avoided. In general, the dishwasher controls the humidity in the cavity through a hot air drying assembly, such as drying tableware through hot air after washing, such as circulating hot air periodically (time sequence and time timing control) in a storage mode, so as to reduce the risk of moisture regain and avoid odor, bacterial growth and the like. The hot air drying mode has the following problems: firstly, hot air is started periodically to dry (blindly in time sequence), so that the air cannot adapt to differences and changes caused by different areas, climates and floors; secondly, the timed hot air drying is limited by operations such as power on/off/plugging in and out, forgetting to set a storage mode, and not knowing how long to set a storage period is proper (the cleaning storage function needs to be repeatedly started after expiration), so that the customer experience is greatly influenced; thirdly, regular hot air drying brings about the increase of energy consumption, but the drying efficiency is low, and the conditions of humidity increase cannot be accurately met, and the moisture regaining weather with high humidity cannot meet the drying requirements and conditions. Therefore, the function of intelligently adjusting the humidity in the cavity of the cleaning machine is required to be designed, so that the humidity in the cavity is controlled in a range suitable for storing tableware, the energy conservation and emission reduction to a large extent can be realized, and the problems that the storage mode is forgotten to be set and the pain points such as the storage period (the cleaning storage function needs to be repeatedly started after expiration) are not known due to the operations such as power on and off, power supply plugging and unplugging and the like are solved. At present, the humidity of the cavity is generally detected by a humidity sensor, and then the humidity of the cavity is controlled according to the detected signal.

The intelligent cleaning machine comprises an inner container and a door body arranged on the front surface of the inner container, wherein an exhaust component is arranged on the door body, a hot air component and a respirator component are arranged on the side wall of the inner container, the exhaust component and the respirator component both comprise a humidity sensor capable of detecting the humidity of the air inside the inner container, and a temperature sensor capable of detecting the water temperature of the inner container is arranged inside the inner container. However, the humidity sensor is arranged in the exhaust assembly, so that the humidity of the air flow in the washing cavity can be detected, the humidity of the air flow outside the washing cavity cannot be detected, and if the humidity of the external air is high, the phenomenon of moisture regain in the washing cavity is very easy to occur.

Disclosure of Invention

The first technical problem to be solved by the utility model is to provide a mounting structure of a sensor for a dish washer, which can detect the air flow in a washing cavity and the air flow outside the washing cavity.

The second technical problem to be solved by the utility model is to provide a dish washer applying the mounting structure aiming at the current state of the art.

The technical scheme adopted by the utility model for solving the first technical problem is as follows: a mounting structure for a sensor on a dishwasher includes

The mounting plate is provided with an exhaust port which is used for being in fluid communication with a washing cavity of the dish washer;

the exhaust pipe is arranged on the mounting plate and is provided with an air inlet and an air outlet hole which is in fluid communication with the air inlet, and the air inlet is correspondingly communicated with the air outlet;

Therefore, the air flow can quickly reach the air outlet, and the air flow does not have large air flow, so that a large amount of condensed water is not condensed on the sensor.

In order to prevent condensed water from accumulating on the sensor, the sensor is provided with a guide rib which extends vertically and inclines. Therefore, condensed water condensed on the guide rib can flow downwards along the guide rib, and the phenomenon that the condensed water is hung on the sensor to cause inaccurate reading or the sensor is wet for a long time to cause short circuit is avoided.

The mounting plate can be any one side wall of the dish washer, but the side wall of the box body is generally thinner, and a sensor and an exhaust pipe are not convenient to be arranged in the side wall of the box body, so the mounting plate is a door body used for opening and closing an opening of the front side of a washing cavity of the dish washer, the cavity is positioned at the lower part of the door body in a state that the door body closes the washing cavity, and the exhaust pipe extends vertically. The door body is generally thicker, so that a sensor and an exhaust pipe can be conveniently installed in the door body.

In order to be convenient for install the blast pipe, the door body is including setting up side by side and the interior door body and the outer door body that link to each other, the gas vent is located on the interior door body, the blast pipe is located between interior door body and the outer door body, have the clearance formation between the lower part of interior door body and the lower part of outer door body the cavity. If the door body is an integral part, the exhaust pipe and the sensor are not convenient to install in the door body, and the door body is in split design, and the exhaust pipe and the sensor can be firstly installed on the inner door body or the outer door body and then connected with the inner door body and the outer door body.

For being convenient for install blast pipe and sensor, fixedly be equipped with the installed part in the cavity, set up on the installed part and vertically link up and towards outer door body open-ended recess, the part of blast pipe is inlayed and is established in the recess, be equipped with the caulking groove on the installed part in the side of recess, the caulking groove is opened towards one side of outer door body, the sensor part is inlayed and is established in the caulking groove.

In order to limit the sensor in the caulking groove, a buckling foot which can be propped against the sensor is arranged at the opening of the caulking groove facing to the outer door body, and the buckling foot can deflect towards or away from the caulking groove, so that the sensor can be detachably arranged in the caulking groove.

In order to prevent the air current that flows from the apopore, continue to flow upwards after flowing through the sensor, erode the electrical components of installing between interior door body and outer door body, the installed part extends along left and right directions, still be equipped with the sealing strip between installed part and the outer door body, the sealing strip extends along left and right directions, the detection end of sensor is located the below of sealing strip. So that after the air flow reaches the detection end of the sensor, the upward flow is blocked by the sealing strip.

Preferably, the sensor is a temperature sensor or a humidity sensor or a temperature and humidity sensor.
