Technical Field

[0001] This utility model relates to the technical field of elevator ventilation devices, specifically a ventilation device for elevator services. Background Technology

[0002] Elevator air conditioning is an air conditioning system specifically designed for elevator cars. It is mainly used to improve the comfort of the environment inside the elevator, especially in high-temperature, enclosed, or high-traffic environments.

[0003] In the existing technology, elevator air conditioning still has the following problems when in use:

[0004] Elevator cars are mostly made of stainless steel. Stainless steel itself has a low temperature value. When the elevator air conditioner is running, the air conditioner air comes into direct contact with the air outlet on the top of the elevator car, which can easily form condensation and produce water droplets inside the elevator.

[0005] The existing method involves attaching insulation material to the inside of the air outlet to prevent cold air from directly contacting the inner wall of the outlet and causing water droplets. However, in actual use, the insulation material tends to loosen over time due to the reduced adhesive strength, creating gaps between the insulation material and the inner wall of the outlet. Cold air then enters these gaps, affecting the airflow and causing water droplets to form again. Therefore, this paper proposes a ventilation device for elevator services. Utility Model Content

[0006] The purpose of this utility model is to provide an air exchange device for elevator services in order to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an elevator service ventilation device, comprising an elevator air conditioner consisting of an air conditioner body, an air intake, an air exhaust, and a ventilation hose. The air intake and air exhaust are fixed to one end of the air conditioner body and connected to the air conditioning system inside the air conditioner body. The air exhaust is connected to a conical connector via a ventilation hose. A guide component is connected to the front end of the conical connector. The guide component is installed inside the elevator car air outlet to provide airflow for cold air and to separate the cold air from the elevator car air outlet.

[0008] The air guiding assembly includes an air guide cover, a diversion port, and an air outlet protrusion;

[0009] The air guide cover is installed inside the air outlet of the elevator car. The diversion port is opened at the bottom of the docking slot and penetrates the bottom of the air guide cover. The air outlet protrusion is fixed to the bottom of the air guide cover and aligned with the diversion port. The air outlet protrusion penetrates the ventilation slot of the air outlet of the elevator car to the inside of the elevator car.

[0010] The channel formed by the diversion port and the air outlet is used to guide the cold air entering the air guide hood into the elevator car.

[0011] As a further improvement of this utility model: multiple diversion ports are arranged in a matrix at the bottom of the air guide shroud, and the number of air outlet protrusions matches the number of diversion ports;

[0012] Furthermore, the number, position, and shape of the air outlet protrusions correspond one-to-one with the number, position, and shape of the ventilation slots at the air outlets of the elevator car.

[0013] As a further embodiment of this utility model: the front end of the tapered connector is integrally formed with a pair of plugs, and the top of the air guide is fixed with a mating groove seat, wherein the pair of plugs and the inner wall of the mating groove seat are in an interference fit.

[0014] As a further improvement of this utility model: the air guide cover, docking slot, diversion port, and air outlet protrusion are formed by injection molding, and the conical connector and plug are formed by injection molding.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up the air guide component, when the elevator air conditioner is running, the cold air is delivered to the inside of the air guide hood through the exhaust port, ventilation hose, conical connector 105, and butt joint, and then distributed to each air outlet through multiple diversion ports, and finally delivered to the inside of the elevator car through the air outlet. During this process, the cold air does not come into contact with the metal surface of the elevator car, which can effectively avoid the formation of condensation droplets and further improve the user experience of the elevator air conditioner.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 In this embodiment of the utility model, an elevator service ventilation device includes an elevator air conditioner 1 consisting of an air conditioner body 101, an air intake 102, an air exhaust 103, and a ventilation hose 104. The air intake 102 and the air exhaust 103 are fixed to one end of the air conditioner body 101 and are connected to the air conditioning system inside the air conditioner body 101. The air exhaust 103 is connected to a conical connector 105 through the ventilation hose 104. The front end of the conical connector 105 is connected to a guide component 2. The guide component 2 is installed inside the air outlet of the elevator car and is used to guide the cold air and to separate the cold air from the air outlet of the elevator car.

[0021] The air guide assembly 2 includes an air guide cover 201, a diversion port 203, and an air outlet 204;

[0022] The air guide cover 201 is installed inside the air outlet of the elevator car. The diversion port 203 is opened at the bottom of the docking slot 202 and passes through the bottom of the air guide cover 201. The air outlet protrusion 204 is fixed to the bottom of the air guide cover 201 and aligned with the diversion port 203. The air outlet protrusion 204 passes through the ventilation slot of the air outlet of the elevator car to the inside of the elevator car.

[0023] The channel formed by the diversion port 203 and the air outlet 204 is used to guide the cold air entering the air guide hood 201 into the elevator car.

[0024] Multiple diversion ports 203 are arranged in a matrix at the bottom of the air guide shroud 201, and the number of air outlet protrusions 204 matches the number of diversion ports 203.

[0025] Furthermore, the number, location, and shape of the air outlet protrusions 204 correspond one-to-one with the number, location, and shape of the ventilation slots at the air outlets of the elevator car;

[0026] The front end of the tapered connector 105 is integrally formed with a plug 106, and the top of the air guide shroud 201 is fixed with a mating groove seat 202. The plug 106 and the inner wall of the mating groove seat 202 are interference fit.

[0027] In this embodiment, it should be noted that the air conditioning unit 101 uses a common elevator air conditioning model on the market (such as the elevator air conditioning model PYD-32FR). Its internal structure and operating principle are exactly the same. Therefore, the operating principle of the air conditioning unit 101 will not be described in detail here.

[0028] When using this elevator air conditioner 1, first connect the air guide component 2 to the docking plug 106 through the docking slot 202. The docking plug 106 is fully inserted into the docking slot 202. Through the interference fit structure of the two, the connection between the docking slot 202 and the docking plug 106 can be guaranteed to be stable and mutually sealed (after the docking is completed, a layer of sealing material can be wrapped on the outside of the docking for further sealing).

[0029] Next, the air guide assembly 2 is installed from the top of the elevator car to the inside of the elevator car's air outlet (the air guide assembly 2 and the inside of the elevator car's air outlet can be fixed with adhesive). During this process, the air outlet protrusion 204 penetrates the ventilation slot of the elevator car's air outlet into the elevator car interior. (It should be noted that the existing ventilation slots of the elevator car's air outlet are square slots arranged in a matrix, such as...) Figure 2 The air outlet protrusion 204 in the model is a square slot with a matching matrix distribution. Alternatively, the ventilation slot of the elevator car's air outlet may be a straight slot; in this case, the air outlet protrusion 204 corresponding to the straight slot can be selected.

[0030] Subsequently, when the elevator air conditioner 1 is running, the cold air is delivered to the inside of the air guide hood 201 through the exhaust vent 103, ventilation hose 104, conical connector 105, and butt joint 106, and then distributed to each air outlet 204 through multiple diversion ports 203, and finally delivered to the inside of the elevator car through the air outlet 204. During this process, the cold air does not come into contact with the metal surface of the elevator car, which can effectively prevent the formation of condensation droplets and further improve the user experience of the elevator air conditioner 1.

[0031] Please refer to this carefully. Figures 1-3 The air guide cover 201, docking slot 202, diversion port 203, and air outlet protrusion 204 are formed by injection molding, and the tapered connector 105 and plug 106 are formed by injection molding.

[0032] In this embodiment, the air guide component 2 made of plastic and the conical connector 105 can achieve good heat insulation, avoid cold air from directly contacting the elevator metal for heat exchange, and avoid the formation of condensation. In addition, compared with the problem of easy aging of traditional adhesive insulation materials, the air guide component 2 has a longer service life and has good assembly convenience and economy.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
