Description

Technical Field

[0001] This utility model relates to the technical field of integrated air conditioners, specifically to a structure for preventing condensate dripping in a kitchen air conditioner. Background Technology

[0002] An all-in-one air conditioner is a device used to regulate temperature. This device is suitable for equipment rooms of various mobile communication operators, research institutes, hospitals, enterprises and other units. With the continuous development of technology, the size of these all-in-one air conditioners is gradually shrinking, so they are no longer limited to commercial use. Some all-in-one air conditioners for home use have also begun to appear on the market.

[0003] The aforementioned integrated household air conditioner is mainly used in smaller spaces such as kitchens and bathrooms, hence it is also called a kitchen air conditioner. Since air conditioners used in kitchens are mainly used for cooling in the summer, their main usage time is often less than half a year. Therefore, compared to fixed, non-removable wall-mounted air conditioners, integrated air conditioners are more flexible and can be moved according to the user's needs.

[0004] Chinese patent ZL202420881119.3 discloses: "An integrated air conditioner, comprising: a shell, the shell forming an indoor air intake zone and an indoor air supply zone; a fan volute, the fan volute being disposed within the installation space enclosed by the shell, the fan volute forming a receiving space, an air inlet zone, and an air outlet zone, the receiving space for accommodating an indoor fan, the air inlet zone and the air outlet zone being connected through the receiving space so that airflow entering through the indoor air intake zone and the air inlet zone is guided by the fan volute to the air outlet zone and the indoor air supply zone; and a liquid storage container, the liquid storage container for storing humidifying liquid, the liquid storage container being disposed on the bottom side of the fan volute, and the liquid inlet of the liquid storage container being connected to the receiving space so that liquid injected from the indoor air supply zone is guided by the fan volute to the liquid storage container. When it is necessary to replenish water to the liquid storage container, no additional operation of the container is required; water can be added directly from the indoor air supply zone to the shell, greatly facilitating the replenishment operation of the liquid storage container."

[0005] When considering solutions including those in the aforementioned patents, existing kitchen air conditioners on the market all share a problem: because kitchen air conditioners lack an outdoor unit and are smaller in overall size compared to regular air conditioners, during the operation of the evaporator, it not only absorbs heat from the air passing through it but also from the surrounding air. This results in condensation forming not only on the surface of the evaporator but also on the inner wall of the air conditioner casing around the evaporator. Due to the inadequate condensate collection and drainage structure inside existing kitchen air conditioners, the condensate on the evaporator and the inner wall of the casing flows down the casing, eventually causing condensate to leak out of the machine and affect the operating environment. Furthermore, if the condensate is not drained in time, it can cause frost to form around the evaporator, affecting the normal operation of the machine. Summary of the Invention

[0006] In order to overcome the shortcomings of existing kitchen air conditioners where the condensate inside the air conditioner cannot be collected and discharged in time when the evaporator is working, which affects the external environment and is prone to frost formation, thus affecting the use of the air conditioner, this utility model provides a structure to prevent condensate dripping in a kitchen air conditioner.

[0007] The technical solution of this utility model to solve its technical problem is: a structure for preventing condensate dripping from a kitchen air conditioner, comprising:

[0008] The housing has an air inlet at its rear end and an exhaust outlet at its front end.

[0009] A refrigeration assembly is disposed within a housing and includes at least a compressor, a heat exchanger, and an evaporator, wherein the evaporator is located inside the air inlet, and the compressor, heat exchanger, and evaporator are connected by refrigerant piping to achieve refrigerant circulation among the three.

[0010] The housing is further provided with a drip-proof structure, which includes:

[0011] A water receiving base is provided below the evaporator, and the water receiving base is also provided with a water receiving groove for collecting the condensate on the evaporator;

[0012] A drain pipe, which is connected to the water receiving base and communicates with the water receiving tank, is used to discharge the condensate in the water receiving tank to the outside of the machine.

[0013] Two water guide strips are provided on both sides of the water receiving base, and the water guide strips are located above the water receiving base. The rear end of the water guide strip is provided with a water drain opening. The water guide strip is connected to the water receiving tank through the water drain opening. The water guide strip can guide the condensate on the inner walls of both sides of the shell into the water receiving tank.

[0014] Furthermore, the water receiving base is arranged horizontally and close to the inner wall of the rear end of the shell, so that the condensate on the evaporator and the inner wall of the rear end of the shell can fall into the water receiving tank; the water guide strip is arranged vertically and close to the inner walls of both sides of the shell, so that the condensate on the inner walls of both sides of the shell can fall into the water guide tank; and the rear end of the water guide strip is located directly above the water receiving tank, so that the condensate on the water guide strip can drip from the drain opening into the water receiving tank.

[0015] Furthermore, the water guide strip is also provided with a water guide groove, and the front end of the water guide strip is set higher than its rear end, so that the water guide groove gradually slopes downward toward the water receiving groove.

[0016] Furthermore, the lower end of the evaporator is embedded in the water receiving tank, and there are drip gaps between the two sides of the evaporator and the two side walls of the water receiving tank. The rear end of the water guide strip is located above the drip gaps, so that the condensate on the water guide strip can drip into the water receiving tank through the drip gaps.

[0017] Furthermore, the anti-drip structure also includes two heat insulation pads, which are attached to the inner walls of the left and right sides of the shell so that the heat insulation pads are located on both sides of the evaporator.

[0018] Furthermore, a column is provided at each of the four corners inside the shell, and a heat insulation sleeve is fitted on the column.

[0019] Furthermore, a partition plate is connected to the inner wall of the housing, which divides the internal space of the housing into an upper cavity and a lower cavity. The compressor is located in the lower cavity, while the evaporator, heat exchanger, and anti-drip structure are all located in the upper cavity.

[0020] Furthermore, the refrigeration assembly also includes a liquid pipeline connected to the heat exchanger, the liquid pipeline being connected to an inlet connector and an outlet connector for connecting to an external liquid source, and the heat exchanger being able to form a liquid circulation with the external liquid source through the liquid pipeline.

[0021] Furthermore, the drain pipe is connected to the liquid pipeline so that condensate can enter the liquid circulation of the liquid pipeline through the drain pipe and be discharged to the outside of the machine through the liquid outlet connector.

[0022] Furthermore, the housing is composed of a rear shell and a front cover connected together, with the air inlet located on the rear shell and the exhaust outlet located on the front cover.

[0023] The condensate drainage process of this utility model:

[0024] First, when the evaporator is working, condensate will condense on its surface. Due to the action of the evaporator, condensate will also condense on the inner wall of the shell and the surface of the column around the evaporator. The condensate on the evaporator surface and the inner wall at the rear end of the shell will fall into the water collection groove of the water collection base under the action of gravity, while the condensate on the column and the inner walls on both sides of the shell will fall into the water guide groove of the water guide strip under the action of gravity. The condensate in the water guide groove will then flow down the water guide groove and drip into the water collection groove through the drain opening. Finally, the condensate collected in the water collection groove can be discharged into the liquid pipeline of the heat exchanger through the drain pipe, and will flow in the liquid pipeline along with the liquid used for heat exchange in the heat exchanger, and finally be discharged together with the liquid from the liquid outlet joint.

[0025] The beneficial effects of this utility model are as follows:

[0026] 1. It is equipped with a drip-proof structure, which can collect and discharge the condensate generated on the inner wall of the air conditioner casing and the evaporator. This prevents the condensate from dripping out of the casing and causing an invisible impact on the environment, and also prevents the condensate from frosting and hindering the operation of the air conditioner.

[0027] 2. Use a water collection base to collect the condensate on the inner wall of the evaporator and the rear end of the casing, and use a water guide strip to collect the condensate on the inner walls of both sides of the casing, thereby further ensuring that all the condensate inside the air conditioner can be collected and discharged in a unified manner.

[0028] 3. A heat insulation pad is installed on the inner wall of the casing, and a heat insulation sleeve is also installed on the column, thereby reducing the generation of condensate on the inner wall of the air conditioner and further reducing the possibility of condensate dripping and frost forming inside the air conditioner.

[0029] 4. The condensate is collected through the drain pipe and discharged into the liquid pipeline of the heat exchanger. This not only saves space inside the air conditioner, but also allows the condensate to be reused. Attached Figure Description
