Description

Technical Field

[0001] The present application relates to the field of dishwashing equipment, and in particular to an air energy heat pump energy-saving dishwasher. Background Art

[0002] A heat pump dishwasher is a dishwasher that uses heat pump technology and can recycle the required heat from the air. Compared with traditional electric heating dishwashers, it uses the heat in the outside air and has lower energy consumption, environmental protection and economy than directly consuming electrical energy. It currently has good application prospects both in home and industrial environments.

[0003] At present, the working principle of the heat pump is to achieve the effect of heating and cooling by circulating refrigerant. In the heat pump dishwasher, it can absorb heat from the environment, increase the water temperature, and then use it for washing and rinsing. For example, the Chinese utility model patent with the announcement number CN215687614U discloses a heat pump dishwasher, which mainly includes a dishwasher body, a heat pump system, a water receiving tray, a drainage device and a control device, wherein the heat pump system includes components such as a condenser, an evaporator, a compressor, an expansion valve and a heat exchanger. When the dishwasher is turned on, the compressor starts to work, sucks in low-temperature and low-pressure steam, and compresses it into high-temperature and high-pressure steam. These high-temperature and high-pressure steams pass through the heat exchanger to transfer heat to water and increase the water temperature. The high-temperature water can decompose stains and improve the dishwashing effect. At the same time, the high-temperature and high-pressure steam in the evaporator exchanges heat with the low-temperature and low-pressure return water in the heat exchanger, so that the steam condenses and releases heat, which is circulated repeatedly. The dishwasher can use the working principle of the heat pump to save energy and improve the efficiency of dishwashing.

[0004] Regarding the above-mentioned related technologies, during the operation of the heat pump, condensation water may be generated on the surface of the evaporator. A water collecting tray is usually used to collect the condensation water. However, the condensation water will cause the air inside the dishwasher to be relatively humid, which may damage the electronic components. Therefore, the existing defects need to be further resolved. Utility Model Content

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] The embodiment of the present application discloses an air energy heat pump energy-saving dishwasher.

[0037] Reference Figure 1 and Figure 2The dishwasher comprises a dishwasher body 1 and a heat pump system 2 arranged in the dishwasher body 1; wherein the dishwasher body 1 mainly comprises a shell 11, a drawer 12 and a cleaning mechanism 13, the drawer 12 is movably arranged in the shell 11, the cleaning mechanism 13 is arranged in the shell 11 and faces the drawer 12, and the drawer 12 is used for placing bowls; in addition, the cleaning mechanism 13 is connected to the heat pump system 2, and the heat pump system 2 comprises components such as a condenser, an evaporator, a compressor, an expansion valve and a heat exchanger. The specific installation methods of the above components are all existing technologies and are not repeated here; wherein an independent installation cavity 112 is also provided inside the shell 11, and the installation cavity 112 is usually close to the back area of ​​the dishwasher body 1, and the heat pump system 2 is accommodated in the installation cavity 112, and the heat pump system 2 provides heat energy for the cleaning liquid to heat up the cleaning liquid, and then the cleaning mechanism 13 is used to spray and clean the bowls, thereby realizing the dishwashing function.

[0038] At this time, since the heat pump system 2 will produce condensed water during the actual operation, the humidity in the installation cavity 112 is high, which affects the electronic components of the heat pump system 2; based on this, the heat pump energy-saving dishwasher also includes an air circulation component 3, and the air circulation component 3 is arranged in the outer shell 11; at the same time, an air flow channel 111 passing through the installation cavity 112 is also opened on the outer shell 11, and the air circulation component 3 discharges the humid gas in the installation cavity 112 by driving the air circulation, so as to reduce the air humidity in the installation cavity 112.

[0039] Continue to refer to Figure 2 In order to provide flow regulation for air circulation, specifically, the air flow channel 111 is mainly divided into two sections, one of which is located at the bottom of the outer shell 11, penetrating from the outside to the inside and extending into the installation cavity 112, and the other corresponding section is located at the top of the outer shell 11, and also penetrates from the outside to the inside and extends into the installation cavity 112. In addition, the opening end of the air flow channel 111 on the outside of the outer shell 11 is preferably on the appearance surface of the dishwasher. It should be noted that the appearance surface specifically refers to the side surface of the outer shell 11 facing the open space. The reason for this setting is that the dishwasher is usually embedded in a confined space, and most of the surface of the outer shell 11 is opposite to the closed cabinet, which may affect the circulation of gas. Based on this, by setting the opening position at the appearance surface of the outer shell 11, gas exchange is facilitated.

[0040] At this time, since the air flow channel 111 is arranged in two sections, the air flow channel 111 is just close to the top and both sides of the bottom of the installation cavity 112, which is conducive to the humid air to form a one-way flow in the installation cavity 112, is not easy to be turbulent, and has a good flow effect; in addition, since the two ends of the air flow channel 111 are respectively opened at the appearance surface of the dishwasher body 1, the gas exchange is efficient and fast.

[0041] Continue to refer to Figure 2In order to drive the airflow to flow in from one end of the air channel 111 and out from the other end, the air circulation component 3 first includes a fan element 32. Usually, the fan element 32 can adopt a silent fan to reduce the noise generated by the structure and achieve a noise reduction effect. When setting the fan element 32, the fan element 32 can be directly fixed in the housing 11, and the fan element 32 can be installed at one of the branch parts of the air channel 111. At this time, the fan element 32 is mainly used to drive the airflow to be drawn out of the housing 11. At this time, negative pressure will be generated in the installation cavity 112. The air will circulate in the installation cavity 112 driven by the negative pressure, and the drier air will be supplemented by the other branch part of the air channel 111 to achieve the air circulation effect. The overall process is efficient and sustainable, with low energy consumption and good energy-saving performance.

[0042] In addition, because there are usually some hair or dust impurities in the external environment, they may flow into the installation cavity 112 with the air flow. If the impurities are deposited on the components, the heat dissipation of the components may be affected. Based on this, the air circulation component 3 also includes a filter component 31 arranged on the dishwasher body 1.

[0043] Specifically, refer to Figure 3 The filter component 31 is mainly located at the opening end of the air flow channel 111 close to the outer side of the shell 11. A group of filter components 31 are respectively provided at the two openings of the air flow channel 111. In this embodiment, one group is selected for description.

[0044] The filter component 31 mainly includes a filter frame 311 and filter cotton 314, wherein the outer edge contour of the filter frame 311 is a rectangular frame structure, and accordingly, it can be combined with Figure 4 A accommodating recess is provided on the surface of the shell 11, the accommodating recess matches the outer contour of the filter frame 311, and the accommodating recess is connected to the air flow channel 111; at this time, the filter frame 311 can be placed in the accommodating recess, and the setting of the accommodating recess can make the appearance smoother and more beautiful.

[0045] In addition, a mesh sheet 312 is also provided inside the frame of the filter frame 311, and a plurality of mesh channels are provided through the mesh sheet 312. The number of mesh channels can be set according to actual needs, and no specific restrictions are made here. At this time, the filter frame 311 is set on the dishwasher body 1, and the mesh sheet 312 can block and cover the opening of the air flow channel 111, and is used to filter some larger impurities such as hair and plastic sheets. In addition, the filter cotton 314 is fixedly installed on the inner wall of the mesh sheet 312 and covers the mesh channel; usually, the filter cotton 314 can use a breathable sponge structure, and at this time, the filter cotton 314 can isolate relatively fine dust, achieve a double isolation effect, and significantly improve the filtering effect.

[0046] Continue to refer to Figure 3 During long-term use, impurities may adhere to the surface of the filter component 31, causing gas flow obstruction. Therefore, in order to ensure that the humid gas can be circulated and discharged smoothly, the filter component 31 is detachably arranged on the housing 11; wherein, the dishwasher body 1 has a male buckle 4, which can be a barb-shaped rod hook, made of plastic material to obtain an elastic buckling effect, and the male buckle 4 can be fixedly installed on the housing 11 by screws. Correspondingly, a female buckle 5 with a concave block structure is fixedly installed at the corresponding position of the filter frame 311, and the female buckle 5 can be movably buckled with the male buckle 4. On the one hand, when the male buckle 4 and the female buckle 5 are buckled with each other, the filter frame 311 is fixedly installed. On the other hand, because the male buckle 4 is elastic, the filter component 31 can be disassembled by peeling the male buckle 4 from the female buckle 5, so as to regularly clean dust and impurities, or replace the filter cotton 314, so as to ensure that the humid air is discharged smoothly, and the convenience of use is improved.

[0047] It should be noted that, in order to ensure that the filter component 31 has good stability during installation, the mutually cooperating male buckles 4 and female buckles 5 can be set in multiple groups, such as two groups, three groups or four groups, wherein the multiple groups of male buckles 4 and female buckles 5 are evenly arranged along the periphery of the filter component 31 to apply multi-directional fixing force to the filter component 31, and the installation stability of the filter component 31 is improved. In this embodiment, the mutually cooperating male buckles 4 and female buckles 5 are set in two groups as an example, and the two groups of mutually cooperating male buckles 4 and female buckles 5 are respectively located on opposite sides of the filter frame 311, and the specific number of male buckles 4 and female buckles 5 is set according to actual needs, and no specific limitation is made here.

[0048] Reference Figure 3 and Figure 5 In order to further improve the accuracy of the installation of the filter frame 311 to the housing 11, a positioning protrusion 113 is integrally connected to the side of the housing 11 facing the housing 11. The positioning protrusion 113 is a cylindrical structure in this embodiment. Correspondingly, a positioning recess 3111 is recessed from the outside to the inside on the surface of the filter frame 311, and the positioning protrusion 113 and the positioning recess 3111 are plugged and matched. Based on this, under the mutual plug-in positioning action of the positioning protrusion 113 and the positioning recess 3111, the assembly position of the filter frame 311 is more accurate and not easy to deviate, which is conducive to the accurate and quick assembly of the filter frame 311, and the portability is improved.

[0049] Reference Figure 6In some areas with high air humidity, the dehumidification effect of the installation cavity 112 may be affected to a certain extent by air circulation alone; based on this, in order to improve the humidity reduction effect, the filter frame 311 is provided with a desiccant placement portion 313, wherein the desiccant placement portion 313 is a cross-bar group structure in this embodiment, and the ends are respectively fixedly connected to the four sides of the filter frame 311, and a storage groove is recessed from the outside to the inside on the desiccant, and a plurality of ventilation holes are also penetrated on the desiccant placement portion 313; at this time, a desiccant can be placed in the desiccant placement portion 313, such as quicklime desiccant, magnesium chloride desiccant, calcium chloride desiccant, soda lime desiccant or phosphorus pentoxide desiccant, silicate desiccant and other desiccant products, and the desiccant dries the humid gas in the airflow through the ventilation holes to reduce the possibility of humid air being inhaled into the installation cavity 112, and the dehumidification effect in the dishwasher body 1 is further improved.

[0050] At the same time, a cover plate 315 is installed at the opening of the storage slot by snapping, and the cover plate 315 can cover the desiccant located in the desiccant placement part 313 to prevent the desiccant from falling off and separating, thereby improving the stability during installation.

[0051] Replay Figure 2 , so that the dishwasher meets the drying working conditions while reducing its energy consumption in the dehumidification process as much as possible. The dishwasher also includes a humidity sensor 6 and a controller 7. The humidity sensor 6 is fixedly installed inside the housing 11 and is located in the installation cavity 112; wherein, the humidity sensor 6 can pre-adjust its settings, for example, when the relative humidity in the air is above 50% or below 50%, different humidity signals will be triggered respectively. At the same time, the controller 7 can be selected as a PLC controller 7, and the controller 7 is electrically connected to the humidity sensor 6 and the fan element 32 in the air circulation component 3 respectively. At this time, the receiving end of the controller 7 can receive the humidity signal, and generate a start-stop signal based on the humidity signal detection value of the humidity sensor 6 and send it to the fan element 32; wherein, when the relative humidity is above 50%, a start signal is issued, and the fan element 32 is controlled to start, so as to realize air circulation dehumidification; in addition, when the relative humidity is below 50%, a stop signal is issued, and the fan element 32 is controlled to stop. Through the cooperation between the controller 7 and the humidity sensor 6, the air flow can be controlled according to the actual situation, and the dehumidification action is more energy-saving and intelligent.

[0052] The implementation principle of the air energy heat pump energy-saving dishwasher in the embodiment of the present application is as follows: by starting the fan element 32 in the air circulation component 3, the air inside the shell 11 can be exchanged with the external circulation, and then the internal humid air is replaced to the outside of the dishwasher body 1. At the same time, after the filtering effect of the filter component 31, dust and impurities are isolated from the outside, and under the action of the desiccant, dry external air is supplemented into the dishwasher body 1, the air humidity inside the dishwasher is reduced, and the working environment of the electronic components is optimized and adjusted.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
